Description

ate

about: 1.. The invention relates to light industrialization and can be used to make blanks for packaging from cardboard webs, for example for packaging finished shoes. A known machine for the manufacture of blanks for packing boxes of cardboard canvases, comprising guiding rolls located on the base, guides, a carriage mounted in the guides, a cutting mechanism arranged on the carriage, including transporting rollers and replaceable gears of the cutting tools, and a carriage movement L L When using Such a machine shows a significant deviation of the width and length of the workpiece from the given ones. The aim of the invention is to improve the quality of the boxes By providing a constant width of the workpiece. To achieve this goal, a machine for the manufacture of blanks for packing boxes of cardboard canvases, comprising roll carriers on the base, guides, mounted in a carriage guide, a cutting mechanism mounted on the carriage, including transporting rollers and interchangeable shears of cutting tools, and a carriage movement actuator It has a means of stabilizing the cardboard web, including rollers, successively located on the carriage in the direction of moving the web between the first roll Ikami mechanism nesting and roll holder. The cutting mechanism contains a means for adjusting the length of the workpiece, including cuts made in one of the mixing gears along an arc and bolts installed in the cuts to secure the gear on the shaft of the cutting mechanism, FIG. 1 shows a machine for the manufacture of blanks for packing cartons of cardboard web, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2; ka fig. 4 shows a section B-B in FIG. I; in fig. 5 is a cross-section of the FIG. one; in fig. 6 is a section DD-D in FIG. I; in fig. 7 — node I in FIG. 6; in fig. 8 is a view E of FIG. 7. 62 A machine for the manufacture of blanks for packaging from cardboard canvases contains located on. base 1 roll holder 2, guides 3 on which a carriage 4 is installed, a nesting mechanism placed on the carriage, including transport rollers 5, interchangeable gears 6, a movable knife 7 and a stationary knife 8, a carriage moving actuator 9. The machine is equipped with a means for stabilizing cardboard sheet in the form of rollers 10, successively located on the carriage 4, between the transporting rollers 5 of the nesting mechanism and the roll holder 2. The nipping mechanism contains means for adjusting the length of the workpiece, including those made on one and interchangeable gears 6 are slotted along the arc and bolts 11 installed in the recesses to fasten gear 6 on the shaft 12 of the cutting mechanism, and five shafts are made to ensure that three replaceable gears 6 are mounted on them. The cutting mechanism is equipped with an actuator 13 having a gearbox 14. On The base 1 is fixed to the frame 15, on which the roll holder mounted in the bearing seats 16 is mounted, and the lever 17, which has a knife 18, freely rotating p with screw 19 about its axis. The rollers 10 are mounted in two cheeks 20, and on the mandrels 21 of the mechanism, cutting sector knives 22 and strips 23 fixed on the rings 24. The frame 25 is provided with a roller 26, and on two shafts 12 and 27 the extruding rollers 28 and transporting rollers 5 are installed. A machine for the manufacture of blanks for packing boxes of cardboard web works as follows. Turning on the drive 13, through the gearbox 14, the shaft 29 is rotated and, through one of the interchangeable gears 6, the shaft 12 is rotated, on which the rollers 28 and the transport rollers 5 are pressed, which are then rotated beyond the roll of cardboard 30 with the roll holder 2. Then the strip is cut off the knife 18 connected with the lever 17. The strip is cut from the roll 30 under the action 3

The transporting rollers 5 are pulled through the stabilizing rollers 10, thereby eliminating the transverse oscillation of the strip during movement into the cutting mechanism.

Next, the strip through the roller 26 enters between the shafts 12 and 27 of the first pair of the cutting mechanism, in which the sector blades 22 execute longitudinal slots on the strip blank, and at the same time using the strips 23 apply the nonepe4iuie creasing.

With the passage of the strip between the shafts 12 and 27 of the second pair, the longitudinal creases are applied by the extrusion rollers 28, then the strip is conveyed by the conveying rollers 5 to the fixed knife 8 and cut off by the movable knife 7 when they are in contact.

During the operation of the machine, the movement of the carriage 4 is carried out by the actuator 9 through the screw 31, the gear coupling 32, the gearbox 33. Col. I2II564

The teeth of the three replaceable gears 6 is calculated so that when the strip is fed by the transporting rollers 5 by an amount equal to the length of the calculated cut, the knife 7 makes one revolution per I second.

To cut a certain width of the strip, the lever 17 with the knife 18 and the mechanism are cut so that the lever 17 with the foot 18 is located At the required distance from the end of the roll, and the axis of the mechanism is cut symmetrically relative to the strip of material in order to withstand required aspect ratio in the transverse direction relative to the strip.

The use of the invention makes it possible to improve the quality of manufacturing packaging boxes made of cardboard canvases by ensuring that the dimensions of the preform are constant in the width direction and that the length is finely adjusted.
