Description

Multi-column stick packing machine

technical field

The invention relates to a packaging machine, in particular to a multi-row strip packaging machine which continuously performs bag making and packaging through automatic operation.

Background technique

In the prior art, during the packaging process of the strip packaging machine, the film needs to be transported first. In the prior art, the way of transporting the film is mostly to use the film release roller to transfer the film on it to the next process through rotation. The position, wherein the power of the rotation of the film release roller is mostly driven by the frictional force of the parts that are in contact with the film release roller. After the film is transported, it is necessary to cut the size of the film as needed, because the packaging film used as a package is usually large in size when it is transported, and the width needs to be cut first, so it is necessary to set up a cutting knife mechanism . Then the packaging film is processed by the metering mechanism and the bag forming mechanism. After the packaging film processed by the bag forming mechanism passes through the longitudinal sealing mechanism, it will enter the horizontal sealing/mechanism. The function of the horizontal sealing mechanism is to seal the packaging film in the horizontal direction. . Finally, the packaged finished product is cut off by the cutting mechanism.

The problem with existing multi-row packaging machines is that the existing horizontal sealing mechanism mostly adopts a fixed method, and when heat sealing, the heat sealing plate is mostly directly pushed by the cylinder, and the heat sealing plate reciprocates through the curved slider mechanism However, due to the mechanical stress relationship and the error caused by the installation gap during the installation process, the two heat-sealing plates cannot be completely meshed when they are closed, which seriously affects the heat-sealing effect.

For this reason, the application number is CN200720083285.5 in the prior art, the application date is 2007-1-23, and the utility model patent named "vertical packaging machine" is proposed, and its technical scheme is as follows: The present invention relates to a vertical packaging machine Packaging machine, including roll film support mechanism, tape transport support mechanism, bag forming former, longitudinal sealing mechanism, horizontal sealing mechanism and cutter mechanism; bag forming former is composed of former and core tube, with symmetrical Two rubbing wheels, the rubbing wheels are directly driven by two motors respectively; the horizontal sealing mechanism is composed of two pairs of racks and pinions, and the two pairs of gears are respectively driven by two motors, and the racks are equipped with heat-sealing blocks. Due to the adoption of the above structure, the present invention not only has simple mechanism, simple use and convenient maintenance, but also has low energy consumption.

The above-mentioned patents use gears and racks to drive the heating block of the horizontal sealing mechanism to perform relative motion to realize heat sealing. Although the use of gears and racks can better make the two heating blocks reciprocate, it is easy for the two sets of gears and racks to be set separately. The movement on both sides of the horizontal sealing mechanism is inconsistent. If there is a slight deviation in installation or design, it will easily cause the rack and pinion on both sides of the horizontal sealing mechanism to be out of sync or to deviate in direction.

For example, the application number is CN200920158318.7, the application date is 2009-5-22, and the utility model patent named "multi-row packaging machine horizontal sealing and cutting device" has a technical scheme as follows: The present invention relates to packaging machinery, especially a multi-row packaging machine Horizontal sealing and cutting device for column packing machine. Including: mobile platform, horizontal sealing mechanism, cutting mechanism, horizontal sealing mechanism and cutting mechanism are installed in the mobile platform, the mobile platform has a rectangular parallelepiped frame structure, and through holes are respectively set on both sides of the front and rear frames, and the through holes are set There are movable connecting rods; the horizontal sealing mechanism is composed of a front sealing plate and a rear sealing plate. The front sealing plate and the rear sealing plate are respectively fixed on the front support plate and the rear support plate. On the rod, there are fixed seats on both sides below the front support plate, and an air cylinder is arranged between it and the mobile platform; the cutting mechanism is composed of a cutting knife, a cutting cylinder, and a limit cylinder. The cutting knife is placed in the front sealing plate. The cut-off cylinder that is sleeved on the front support plate is connected, and the limit cylinder is installed on the front support plate fixing seat. The device can horizontally seal and cut multiple rows of packaging bags at the same time, so that the work efficiency is greatly increased, the production process is reduced, and the equipment cost is also reduced.

The above-mentioned patent is to use a horizontal guide rod to realize a motor to drive the two horizontal sealing plates to move relative to each other at the same time. Although the problem of guiding is solved to a certain extent, it still does not solve the problem if there is a gap between the two horizontal sealing plates during the heat sealing process. The problem of not fitting.

Another example is the patent application number CN200820025118.X, the application date is 2008-06-29, and the name is a utility model patent named "horizontal sealing device for vertical strip bag-shaped flexible packaging machine". The technical scheme is as follows: Vertical strip-shaped bag-shaped flexible packaging machine Horizontal sealing device, one end of the two guide posts mounted on a support is connected with a fixed plate, the fixed plate is elastically connected with an outer horizontal seal, and the push plate opposite to the outer horizontal seal is connected with an inner horizontal seal block, the inner transverse seal block is connected with one end of a guide shaft worn on the support, the other end of the two guide posts is connected with a bracket, the other end of the guide shaft is connected with the cylinder body of a cylinder, and the piston rod of the cylinder is connected with the The bracket is connected, and two connecting rods are hinged on the cylinder body and the bracket respectively. The two connecting rods on the cylinder body and the two connecting rods on the bracket are connected with each other respectively to form a parallelogram. A fork is hinged, and the other ends of the two fork are respectively hinged with the support or the parts fixedly connected thereon. The invention has reasonable structure, large working stroke, stable operation, low working noise and long service life.

Another example is the patent application number CN200920187634.7, the application date is 2009-09-18, and the utility model patent named "horizontal sealing mechanism of packaging machine", its technical scheme is as follows: The invention discloses a horizontal sealing mechanism of a packaging machine The sealing mechanism includes a support frame, guide shafts are slidably installed on the two side edges of the support frame, a servo motor is installed on the support frame, a swing arm is installed on the output shaft of the servo motor, and front ends are hinged at both ends of the swing arm. The driven arm, the rear driven arm, and the two sides of the swing arm are respectively provided with a front horizontal seal drive block and a rear horizontal seal drive block which are slidably fitted on the guide shaft, and the other ends of the front follower arm and the rear follower arm are respectively hinged. In the middle of the front horizontal seal drive block and the rear horizontal seal drive block, a stopper is installed on the end of the guide shaft outside the front horizontal seal drive block, and the other end of the guide shaft is fitted with a front horizontal seal slider. A stopper is installed at the end of the guide shaft on the outside; a rear transverse seal slider is slidingly sleeved on the middle part of the guide shaft, and a push rod is connected between the rear transverse seal slider and the rear transverse seal driving block. The invention makes the horizontal sealing of the packaging machine fast and accurate, and improves the equipment efficiency.

The above two patents are realized by the cylinder pushing the connecting rod, and the connecting rod drives the horizontal sealing module to reciprocate. The defect of this structure is that the heat sealing module reciprocates along a single guide rod, although the form of the guide rod can reduce the two The position of the horizontal sealing module is shifted during heat sealing, but it is still difficult to make the two horizontal sealing modules fit together completely during heat sealing. And when there is still a gap when the two heat-sealing modules are closed, an additional cardboard or metal sheet is needed to align the heat-sealing modules. When a large packaging machine is working, this situation will be more prominent, and it is more likely to cause misalignment of the seal during heat sealing, resulting in the problem of lax sealing.

So to sum up, the two horizontal sealing seats of the horizontal sealing mechanism of the existing multi-row packaging machine cannot be completely fitted due to the gap in the horizontal sealing process, resulting in the problem of lax horizontal sealing and poor horizontal sealing effect .

working principle:

The film release motor indirectly drives the film support roller to rotate, conveys the packaging film through the film moving mechanism, and sends the packaging film into the cutting mechanism. When the entire packaging film passes through the cutting knife mechanism, the n+ in the cutting knife mechanism 1 pair of rotating upper and lower cutting knives cut the packaging film according to the actual required width, and the cut n strips of packaging film enter the bag forming mechanism respectively, and the n strips of packaging film entering the bag forming mechanism slow down It slowly becomes a tubular packaging film. After it is fully formed, the vertical sealing mechanism will longitudinally seal n tubular packaging films at the same time under the action of the cylinder. After the longitudinal sealing is completed, it will enter the horizontal sealing mechanism. The packaging film is heat-sealed horizontally for the first time by two horizontal sealing seats along multiple horizontal sealing guide shafts on both sides at the same time. Rotate at a certain angle to compensate for the differential gap between the two, and then the horizontal sealing device pulls down the packaging film for a bag-long distance, and then releases the packaging film and returns to the initial position to perform a second transverse heating on multiple packaging films arranged side by side. Seal, the principle is the same as the first horizontal seal. At this time, the packaging film that has been heat-sealed twice enters the cutting mechanism, and the end of the tubular packaging film is cut along the middle position of the heat-sealing in the transverse direction, thus completing the production of a multi-row complete packaging bag.

Compared with the prior art, the present invention has the advantages of:

1. The present invention can simultaneously cut a large-sized packaging film into a plurality of smaller-sized packaging films of specified size. Under the action of the sealing seat, the production of multiple packaging bags can be completed at the same time, which greatly improves the production efficiency.

2. The present invention connects the horizontal seal seat and the beam slider through the pin shaft. When there is still a gap when the two horizontal seal seats are closed, the horizontal position of the horizontal seal seat can be automatically fine-tuned through the pin shaft. The seat surrounds the pin shaft, and automatically compensates and meshes with the other horizontal seal seat; it adopts the technical scheme of combining multiple guide shafts with rack and pinion. This structure ensures that the horizontal seal seat will The horizontal seal is carried out along the predetermined line, because the guide shaft can make the horizontal seal seat move without deviation, and the meshing rack and pinion can effectively drive the two horizontal seal seats to move oppositely at the same time, which simplifies the structure and improves the efficiency. Horizontal sealing quality and efficiency.

3. The present invention can provide space for fine-tuning the horizontal sealing seat by adopting the elliptical pin hole, and automatically fills the gap, so that the horizontal sealing seat can automatically compensate and engage. Since the floating mechanism is provided, the floating mechanism can drive the horizontal sealing device to reciprocate up and down Movement, in the process of downward movement, if the horizontal seal seat is in the closed state, it will play the role of pulling the membrane, which saves the trouble of setting up an additional membrane pulling device and simplifies the overall structure.

4. When the object to be packaged enters the packaging film, since the object to be packaged falls from a high place, if the packaging film is at rest at this time, the impact force on the object to be packaged is relatively large, which will easily cause the packaging film to be damaged and the packaging If the appearance of the object is damaged, if the floating mechanism drives the horizontal sealing device down, it is equivalent to giving a buffer force to the object to be packaged, which can reduce the impact on it and protect the packaging film and the object to be packaged from damage.

5. The present invention realizes the eccentric movement by adopting the eccentric cam structure, and at the same time can change the eccentric distance by adjusting the rotating handle, and it can be adjusted according to the actual length of the packaging bag required.

6. The film release detection roller of the film moving mechanism of the present invention floats up and down in the vertical guide grooves on the two film moving fixed plates depending on the tension of the packaging film, and can most intuitively reflect the tightness of the packaging film on the initial station. That is to say, when the packaging or cutting station is working, the packaging film is pulled. Since the motor drives the shaft of the film supporting roller to rotate intermittently, when the shaft of the supporting film roller stops rotating, the pulling force of the packaging film at the next station will be pulled The film release detection roller is raised to a certain height, otherwise it will fall to the original position. Compared with the reciprocating motion realized by the pendulum in the comparison document, this linear reciprocating motion has a lower failure rate, simplified structure, and less wear and tear on mechanical parts. Less, and linear reciprocating motion makes the whole film release detection roller more stable when moving.

7. The present invention can simultaneously cut a larger packaging film into a plurality of smaller-sized packaging films of specified size by adopting a slitting knife mechanism. Under the action of the sealing seat and the horizontal sealing seat of corresponding size, the production of multiple packaging bags can be completed at the same time, which greatly improves the production efficiency. The cutter mechanism adopts the upper and lower cutter shafts to respectively drive the cutter to rotate for cutting, and its stability is better. Compared with the case of only one cutter shaft, it can effectively prevent the packaging film from being damaged by the other side. The problem of unsatisfactory film cutting caused by insufficient supporting force.

8. The upper cutting knife and the lower cutting knife of the cutting knife mechanism of the present invention adopt a circular cutting knife, and the circular cutting knife is driven by a shaft to rotate to cut the packaging film, while the ordinary strip cutting knife is Slitting is realized through the up and down reciprocating movement of the blade, and the direction of movement of the rotary slitter cutter is tangent to the direction of movement of the packaging film, so when slitting, its slitting effect is better than that of the strip cutter, and the incision is smoother ,tidy.

9. The present invention overcomes the technical problem of waste caused by too much or too little material in the prior art by adopting the feeding mechanism, and satisfies the working requirements of the automatic operation of the multi-row strip packaging machine, and is easy to operate , avoiding the phenomenon of too much or too little material in the packaging process, avoiding the unqualified finished product, resulting in waste of materials, saving costs, and the feeding effect is very good, further improving the level of integrated operations.

10. The present invention improves the integrated operation level by adopting the first feeding pipe and the second feeding pipe in the feeding mechanism. The metering mechanism is used in conjunction with the feeding mechanism, which overcomes the technical problem of waste caused by too much or too little material in the prior art. It can be designed in multiple rows for batch production, which further improves the level of integrated operation.

11. The present invention saves the structure of the collar forming device through the bag forming mechanism by adopting the bag forming mechanism composed of bag forming roller, bag forming tube and edge guide, and uses the edge guide to cooperate with the bag forming roller and bag forming tube When used together, the packaging film can be changed from a flat packaging film to a tubular packaging film. The edge guide can protect the film from deformation and avoid the high scrap rate in the production process. The structure is simple and saves production costs. Maintenance and In exchange for convenience. Multiple bag forming tubes are arranged side by side to achieve the effect of bag forming for multiple packaging films at the same time.

Since the film release detection roller 114 can slide up and down in the vertical guide groove on the side of the film moving fixed plate 11, the height of the film release detection roller 114 is changed by the tension of the packaging film. When the film release motor drives the film discharge roller 113 to rotate to drive When the film-holding roller shaft 12 rotates to release the film, the film-releasing detection roller 114 will reach the lower position 16 of the film-releasing electric eye from the upper position 15 of the film-releasing electric eye. Stop rotating, and the film release detection roller 114 stops moving down. Since the follow-up process continues, the horizontal sealing device pulls the film to move downward, and drives the film to pull the film release detection roller 114 to move to the upper position 15 of the film release electric eye. When the film electric eye device 14 detects that the film release detection cylinder 114 arrives at the film discharge electric eye up position 15, the film discharge motor starts, and the film discharge cylinder 113 begins to rotate, and works in a cycle like this.

Specifically speaking, the film-releasing electric eye is a proximity switch. When the film-releasing detection roller 114 rises to the upper position 15 of the film-releasing electric eye along with the drawing die, the film-releasing electric eye at this position detects it, and it feeds back a signal to the programmable controller After the programmable controller receives the signal, it sends the signal to control the motor to rotate, and at this moment, the film of the film detection cylinder 114 is dragged and unclamped. Usually, the packaging film floats up and down with the help of the film release detection roller 114. Its stroke generally only floats up and down in the groove. When it reaches the upper position, the motor releases the film, and the film release detection roller 114 falls to the lower position, that is, the film release motor Transmission, only when there is no film support, the support film detection roller will fall to the lowest point, and the detection electric eye installed at the lowest position, that is, the film-free alarm electric eye 111 detects and then feeds back a signal to the programming controller. After the programming controller receives the signal, it sends out a signal to control the buzzer to alarm.

When the supporting film roller shaft 12 stops rotating, the braking device then suspends the transmission of the film to avoid backflow phenomenon. Brake drum 18 axle ends are connected with magnetic powder brake, and during operation, input voltage controls the buffering start of brake drum 18, and stops. A pressing roller 123 on the upper end of the brake drum 18 is equipped with a spring 124, so that the pressing roller 123 is pressed on the brake drum 18, and the pressing roller 123 cooperates with the one-way bearing. The clutch in the magnetic powder brake is closed to achieve the effect of stopping and braking. When the magnetic powder clutch 112 is in operation, the input voltage controls the damping start and stop of the brake drum 18 . The clutch in the magnetic powder brake is closed to achieve the effect of stopping and braking.

The principle of the deviation correction device is: driven by the deviation correction motor 118, the deviation correction screw 119 rotates, and the deviation correction screw 119 is connected with the deviation correction flange seat 120 in a threaded form, that is, when the motor rotates n times, the deviation correction flange seat 120 drives the fixing plate and fixes it. The plate drives the fixed plate to move a distance of n screw rods in the axial direction of the deviation correcting screw rod 119 . The deflection correcting electric eye used to detect the position of the packaging film is an existing electric eye device, which can be installed on the film running fixed plate 1 or other positions according to the actual situation.

In the present invention, a guide roller 122 and a tension roller 121 are also provided. The tension roller 121 is generally between the two guide rollers 122.

An elliptical pin hole is provided on the beam slider 65 at at least one end of the horizontal seal fixing seat 619 . At this time, an elliptical pin hole can be provided on any one of the sliders at both ends, and the transverse seal guide shafts 68 on both sides of the transverse seal seat 63 are arranged symmetrically with respect to the center of the transverse seal seat 63 . Both horizontal seals 63 are equipped with heating devices. Both ends of the horizontal seal guide shaft 68 are fixed on the horizontal seal fixed plate 610, and the horizontal seal cylinder 69 is also installed on the horizontal seal fixed plate 610, and a plurality of horizontal seal fixed plates 610 and connecting plates 612 surround and connect to form a frame structure. The plurality of horizontal seal guide shafts 68 described in this application means at least two horizontal seal guide shafts 68 . The heating device is a heating rod or a heating structure that can be used for heat sealing in the prior art.

The horizontal sealing floating device 62 is connected with the horizontal sealing device 61 through the floating connecting rod 611 and the connecting plate 612 connected with the floating connecting rod 611 . The horizontal sealing floating device 62 includes a horizontal sealing driving motor 613 and an eccentric cam mechanism 614, and the eccentric cam mechanism 614 is connected with the output shaft of the horizontal sealing motor. Eccentric cam mechanism 614 comprises eccentric machine base 615, eccentric adjusting screw rod 616 in eccentric machine base 615, eccentric adjusting rotating handle 617 and eccentric adjusting fixed nut 618, eccentric adjusting rotating handle 617 is connected with one end of eccentric adjusting screw rod 616, in eccentric adjusting screw rod An eccentric adjustment fixing nut 618 is connected to the 616 , and the other end of the eccentric adjustment fixing nut 618 is connected with the floating connecting rod 611 .

When in use, the packaging film that has completed the vertical sealing enters the horizontal sealing mechanism 6. Driven by the horizontal sealing cylinder 69, the two horizontal sealing seats 63 move in reverse through the cooperation of the gear 67 and the rack 66 to press the packaging film together. Under the action of driving motor 613, the eccentric cam mechanism 614 is driven to rotate to lower the entire horizontal sealing device 61 until the length of a bag is drawn, and the horizontal sealing seat 63 is opened. At this time, a sealing is completed, and the function of pulling the film is realized simultaneously. Then the horizontal sealing cylinder 69 is opened, and at the same time, under the action of the horizontal sealing driving electric 613, the eccentric cam mechanism 614 is driven to rotate so that the entire horizontal sealing seat 63 rises to the highest point. At the same time, the vertical sealing pressing cylinder completes another vertical sealing. So repeat.

Since the width of the horizontal sealing seat 63 is similar to the total width of the plurality of side-by-side bag-forming tubes 42, the plurality of side-by-side tubular packaging films processed from the above steps can be horizontally sealed as a whole at the same time.

Also due to the error in processing and assembly and when the two cylinders cannot be extended synchronously, the two horizontal seal seats 63 may not be completely parallel, and the horizontal seal seat 63 is promoted by the horizontal seal cylinder 69, and the two horizontal seal seats 63 are in the position of the gear 67 and the rack 66. Relative movement under mutual engagement, one end is fully engaged, and the other end has a gap, and the pin shaft 64 in the beam slider 65 at the other end of the horizontal seal holder 619 will be displaced along the X-axis in the oval pin hole, automatically Compensate the differential gap between the two to realize the function of free floating and flexible sealing.

Because the crossbeam slider 65 at the two ends of the horizontal seal holder 619 is provided with a pin hole, and the pin hole of one end beam slider 65 is circular, and its shape matches the bearing pin 64, while the pin hole on the other end crossbeam slider 65 is Ellipse, pin shaft 64 can slide in the pin hole of ellipse. At this time, the horizontal seal fixing seat 619 on one side will rotate around the pin shaft 64 corresponding to the circular pin hole on the beam slider 65 . In addition to the ellipse, the pin hole can also be configured as a strip or other shapes that enable the pin shaft to slide therein.

The above-mentioned solution can solve the problem that the horizontal seal cannot be completely fitted due to mechanical stress or the like. And for the situation that the two horizontal seal seats 63 do not fit together due to the asynchronous guidance of the horizontal seal guide shaft 68, all the pin holes can be set as circular, and at this time all the pin shafts can rotate relative to each other in the pin holes , the pin shaft does not need to slide in the pin hole, and the lamination of the two horizontal seals can be realized by relying on inertia.

After the packaging film after horizontal sealing is cut by the cutting mechanism 7, a finished product is formed.

The coding mechanism 8, the color mark tracking mechanism 9 and the cutting mechanism 7 described in this application are all structures in the prior art.
