Detailed Description
The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 6, the grinding wheel gap adjusting device of the pulping machine comprises an adjusting nut 1 and a cover 2, a prompting device 3 is arranged between the adjusting nut 1 and the cover 2, and when a gap exists between the lower surface of the adjusting nut 1 and the upper surface of the cover 2, namely, the gap between the lower surface and the upper surface is larger than zero, the prompting device 3 sends a prompting signal.
The pulping machine in the prior art mainly comprises a machine body provided with a machine cover 2, a static grinding wheel 7 and a movable grinding wheel 8, wherein the static grinding wheel 7 and the movable grinding wheel 8 are arranged in the machine body, the static grinding wheel 7 is connected with a grinding frame 9, one end of the grinding frame 9 extends out of the machine cover 2, an adjusting nut 1 is in threaded connection with the grinding frame 9, and a pressure spring 10 is sleeved on the grinding frame 9. The grinding frame 9 is moved by the rotation of the adjusting nut 1. Due to the structural arrangement, when the adjusting nut 1 rotates, the grinding frame 9 can axially move, and then the static grinding wheel 7 can be driven to move, so that the gap adjusting function is achieved; when the static grinding wheel 7 is stuck to the movable grinding wheel 8, the grinding frame 9 cannot move axially continuously, so that when the adjusting nut 1 is rotated continuously, the adjusting nut 1 moves upwards, the lower surface of the adjusting nut 1 is not in contact with the upper surface of the cover 2, a gap is formed, and when the gap is formed, the prompting device 3 sends a prompting signal to prompt an operator that the static grinding wheel 7 is stuck to the movable grinding wheel 8; an operator can rotate the adjusting nut 1 reversely, so that the adjusting nut 1 drives the static grinding wheel 7 to move upwards, the static grinding wheel 7 is prevented from being attached to the movable grinding wheel 8, and the phenomenon that the motor is burnt out is prevented.
When the adjusting nut 1 is adjusted in a reverse rotation mode, the adjusting nut 1 firstly moves downwards to be in contact joint with the cover 2, and then the static grinding wheel 7 is driven to move upwards. After the adjusting nut 1 is attached to the cover 2, no gap exists between the adjusting nut and the cover, so that the prompting device 3 cannot send out a prompting signal. However, the following phenomena may occur during the conditioning process: that is, when the adjusting nut 1 is rotated reversely, the adjusting nut 1 and the cover 2 are in a fit state (after the prompt signal disappears), but when the static grinding wheel 7 has not moved upward, the static grinding wheel 7 and the movable grinding wheel 8 may still be in close fit, so that it is necessary for the operator to continue to rotate the adjusting nut 1 slightly reversely after the prompt signal disappears.
Furthermore, the prompting device 3 is mainly used for detecting whether a gap exists between the adjusting nut 1 and the cover 2, and if the gap exists, a prompting signal is sent out. Therefore, the prompting device 3 can be realized by adopting various structures, for example, a pressure alarm can be arranged between the adjusting nut 1 and the cover 2, when the adjusting nut 1 is attached to the cover 2, a certain pressure value exists between the adjusting nut 1 and the cover 2, and the pressure alarm does not send out an alarm signal; on the contrary, when a gap is formed between the adjusting nut 1 and the cover 2, the pressure value between the adjusting nut and the cover is smaller or zero, and the pressure alarm sends out an alarm signal.
Example one
The presentation device 3 preferably has the following structure: it includes photoswitch and suggestion component 301, and the power passes through photoswitch and is connected with suggestion component 301, and photoswitch includes photosensitive sensor 300 and control circuit, and photosensitive sensor 300 passes through control circuit and is connected with suggestion component 301, and photosensitive sensor 300 sets up in the recess 200 of cover 2. When a gap is formed between the adjusting nut 1 and the cover 2, light can shine on the light-sensitive sensor 300 through the gap, so that the prompting device 3 sends a prompting signal, and the prompting element 301 can also be fixed on the cover 2 or other suitable positions.
Further, the photosensitive sensor 300 is a photo resistor, and the indication element 301 may be an indicator light and/or a buzzer.
The light sensor 300 is mainly applied to the fields of light-operated small night lights, cameras, monitors, light-operated toys, acousto-optic switches and the like, can sense light and shade changes of light, outputs weak electric signals, and can control L automatic switches of devices such as ED lamps and the like through amplification processing of simple electronic circuits, and is widely applied to automatic control and household appliances, so that specific circuits of the prompting device 3 are well known by persons skilled in the art and can be adjusted according to actual conditions.
In fig. 9, only an indicator light (bulb) is in the prompting element 301: the photoresistor is connected with the resistor R1 in series, and when there is no illumination, namely the voltage at the two ends of the R1 does not reach the starting voltage of the Q1 triode, once the photoresistor is illuminated, the resistance value of the photoresistor rapidly drops, the voltage at the two ends of the R1 rises, the triode is conducted, so that the rear-stage Q2 triode is conducted, the final switch K is turned on, and the bulb works.
In fig. 8, a prompt element 301 is an indicator light and a buzzer, wherein a 555 time-base integrated circuit in the circuit is connected into a typical non-steady-state operation mode, a photoresistor R L and a variable resistor RP form a light-operated trigger circuit, when R L is not irradiated with light, the high resistance state is presented, the voltage division point of R L and RP, namely the 4-pin potential of the 555 time-base integrated circuit is lower, when R L is not irradiated with light, the high resistance state is presented, the voltage division point of R L and RP, namely the 4-pin potential of the 555 time-base integrated circuit is lower, when R L is not irradiated with light, the voltage division point of R L and RP, namely the 4-pin potential of the 555 time-base integrated circuit is lower, (a few time-base circuits are more than 1V), forced reset is released, the circuit immediately oscillates, U1 gives an alarm, and D1 emits light.
Example two
The prompting device 3 of the first embodiment is arranged on the cover 2, and the arrangement mode needs to process the groove 200 on the cover 2 of the existing equipment, so that the strength of the equipment can be reduced, and the processing is inconvenient. As shown in fig. 12 and 13, a base 302 is added to the first embodiment, and the light control switch and the prompting element are arranged on the base 302. Thus, when mounting, the base 302 is fixed to the cover 2 by bolts, adhesive bonding, or the like. When the base 302 is provided, the cover 2 is provided with the connecting groove (3020) without processing the groove 200
EXAMPLE III
The prompting device 3 can also be realized by adopting the following structure, the prompting device 3 comprises a contact switch and a prompting element 301, the power supply is connected with the prompting element 301 through the contact switch, and the on-off between the power supply and the prompting element is controlled through the switch.
As shown in fig. 10 and 11, the contact switch includes a first conductive plate 11 and a second conductive plate 13, the first conductive plate 11 is conducted with the second conductive plate 13 through a conductive ring 12, the first conductive plate 11 and the second conductive plate 13 are both disposed on the upper surface of the cover 2, and the conductive ring 12 is disposed on the lower surface or the lower side surface of the adjusting nut 1.
When no gap is generated between the adjusting nut 1 and the cover 2, the conducting ring 12 is in contact with the first conducting plate 11 and the second conducting plate 13, the first conducting plate 11 is conducted with the second conducting plate 13, and the power supply supplies power to the prompting element 301; on the contrary, when a gap is generated between the adjusting nut 1 and the cover 2, the conductive ring 12 is not in contact with the first conductive plate 11 and the second conductive plate 13, the first conductive plate 11 is not in conduction with the second conductive plate 13, and the power supply does not supply power to the prompting element 301.
The prompting device 301 may also be a bulb, a buzzer, or the like. Taking a bulb as an example, when the structure is adopted, the bulb is lighted when no gap is generated; otherwise, after the gap is generated, the bulb is turned off, and the turning-off of the bulb is the prompt signal.
Example four
The prompting device 3 in the third embodiment is also arranged on the cover 2, and certain inconvenience exists in the mounting and dismounting process. As shown in fig. 14, by the same means as in the second embodiment, a base 302 is added on the third embodiment, that is, the first conductive sheet 11, the second conductive sheet 13 and the prompting element 301 are disposed on the base (302), so that the whole assembly and disassembly are convenient.
Further, as shown in fig. 15, the above technical solution can effectively avoid the occurrence of the motor burnout phenomenon, but there is no reference when adjusting the gap. Therefore, the cover 2 is provided with a dial 4, and the adjusting nut 1 is provided with a scale pointer 5.
When the prompting signal disappears, the gap between the static grinding wheel 7 and the movable grinding wheel 8 is theoretically zero, but an error inevitably exists due to manual operation, namely the gap between the static grinding wheel and the movable grinding wheel is slightly smaller or slightly larger than zero, so that the speed is relatively slow when the adjusting nut 1 is rotated reversely, and the error can be reduced as much as possible.
Because the adjusting nut 1 is in threaded connection with the grinding frame 9, the nut can axially move by a thread pitch after rotating for a circle, and the moving distance corresponding to the adjusting nut 1, namely the moving distance of the static grinding wheel 7, namely the gap between the static grinding wheel 7 and the movable grinding wheel 8 can be known after rotating for an angle. A plurality of scale marks are evenly distributed on the circumference of the dial 4; after the prompt signal disappears, recording which scale mark on the dial 4 the pointer is opposite to; and then, according to the clearance required to be adjusted, the adjusting nut 1 is rotated reversely, so that the pointer is opposite to the required scale mark.
Further, the above reading mode is a manual identification mode, but a digital display mode can be set for reading according to needs. As shown in fig. 7, the digital display device 6 includes an angle sensor and a display 601, the angle sensor is coupled to the display 601, and the rotation angle of the adjusting nut 1 is measured by the angle sensor. The magnetic grid ring 600 in the angle sensor is arranged on the outer side surface of the adjusting nut 1, and a reading head (not shown in the figure) is arranged on the cover 2. After the prompt signal disappears, the digital display device 6 can be started to measure the rotation angle of the adjusting nut 1, and the moving distance of the adjusting nut can be known after the rotation angle is measured.
The measurement of the rotation angle by the angle sensor is well known to those skilled in the art, and can be adjusted and designed according to the actual situation as long as the digital display of the rotation angle can be realized. Specifically, the structures disclosed in the following documents may be referred to or used: a photoelectric encoder rotary pulse display device 601 as disclosed in patent application No. 201310064181. X; a rotation angle detection device, a rotary machine, and a rotation angle detection method disclosed in patent application No. 200980104613.7; the measurement and calculation of rotation angle based on incremental rotary optical encoders disclosed in patent application No. 201410719578.2; an incremental rotary encoder of the type disclosed in patent application No. 201810522106.6, and the like.
The adjusting method mainly adopts reverse lifting after contact to adjust: namely, after the gap between the static grinding wheel 7 and the movable grinding wheel 8 is zero, the gap is adjusted.
The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
