[0002] After the conveyor belt is produced, there will inevitably be bumps or burrs on the edge of the conveyor belt. The conveyor belt that has not been cut and trimmed is prone to vibration when passing through the rollers and rollers. This vibration will not only accelerate the wear of the conveyor belt and related components (such as rollers and rollers). Generally, a sharp blade is used to cut the burrs of the conveyor belt, and the burrs can be effectively trimmed.

At this time, the first magnetic block 18 will be aligned with the second magnetic block 19, thereby attracting the first connecting disk 14 to move upward, so that the connecting rod 17 can be disengaged from the limiting groove 16. When the rotating shaft 7 and the connecting shaft 9 need to rotate together, the rotating rod 13 is rotated first, so that the first magnetic block 18 and the second magnetic block 19 on the second connecting disk 15 are misaligned.

Then, when the connecting shaft 9 rotates, the limiting groove 16 will be aligned with the connecting rod 17, so that the connecting rod 17 can enter the limiting groove 16. At this time, when the connecting shaft 9 rotates, it will drive the rotating shaft 7 to rotate synchronously.

[0037] The inner wall of the hollow block 4 is slidably connected with an inclined connecting frame 20, and the inner wall of the connecting frame 20 is fixedly connected with a filter screen 21.

When the driving blade 10 stops rotating, the waste will slide on the inclined filter screen 21, and then enter the collecting box 22 from the discharging trough 23 to be collected.

[0038] A movable groove 29 connected to the discharge trough 23 is provided in the hollow block 4, and a sealing plate 28 for sealing the discharge trough 23 is slidably connected to the inner wall of the movable groove 29, and a second spring is fixedly connected between the bottom surface of the sealing plate 28 and the movable groove 29, and a connecting groove 33 corresponding to the discharge trough 23 is provided on the sealing plate 28, and a moving component for driving the sealing plate 28 to move is provided on the hollow block 4; after the collecting box 22 collects the waste, the suction force generated by the driving blade 10 during rotation can easily suck the waste in the collecting box 22 from the discharge trough 23 to the hollow block 4, and the above mechanism can firstly seal the discharge trough 23 with the help of the sealing plate 28, and then when the driving blade 10 stops rotating, the sealing plate 28 can be moved upward with the help of the moving component, so that the connecting groove 33 is connected with the discharge trough 23, and then the waste can enter the collecting box 22 from the discharge trough 23, and then the sealing plate 28 is driven to move downward with the help of the moving mechanism, so that the sealing plate 28 can seal the discharge trough 23.

[0039] The moving assembly includes a driving groove 35 opened in the hollow block 4 and connected to the moving groove 29, a round rod 34 is slidably connected in the driving groove 35, the top surface of the round rod 34 is fixedly connected to the sealing plate 28, a third spring is fixedly connected between the bottom surface of the round rod 34 and the inner wall of the driving groove 35, the sealing plate 28 is made of magnetic material, and the top surface of the moving groove 29 is fixedly connected to an electromagnet 41 that is magnetically attracted to the sealing plate 28; in the present application, when the sealing plate 28 needs to move upward, the connecting When the groove 33 is aligned with the discharge groove 23, the electromagnet 41 can be started, so that the electromagnet 41 sucks the sealing plate 28 to move upward, so that the connecting groove 33 is aligned with the discharge groove 23, so that the waste on the filter screen 21 can be discharged into the collection box 22. When the electromagnet 41 is turned off, the third spring will pull the round rod 34 to move downward, so that the round rod 34 drives the sealing plate 28 to reset, so that the connecting groove 33 and the discharge groove 23 are misaligned.

The bottom surface of the connecting frame 20 corresponding to the driving block 26 is fixedly connected with a push rod 27. The driving block 26 can be used to push the push rod 27. The side of the driving block 26 close to the push rod 27 is in an inclined shape. The connecting shaft 9 in the present application rotates at high speed When the sliding rod 25 is in the state of being moved, the driving block 26 and the pushing rod 27 are dislocated.

[0041] Embodiment 2: Figure 7 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a rectangular groove 40 is provided on the inner wall of the feed end of the feed trough 5, a dredging plate 43 is slidably connected to the inner wall of the rectangular groove 40, the dredging plate 43 extends out of the feed end of the feed trough 5 on the side close to the blade 6, a rotating groove 37 is provided in the connecting block 3, a take-up wheel 38 is rotatably connected in the rotating groove 37, a fixed line 42 is fixedly connected to the surface of the take-up wheel 38, the other end of the fixed line 42 is fixedly connected to the dredging plate 43, an elastic rope 36 is fixedly connected between the side of the dredging plate 43 away from the take-up wheel 38 and the inner wall of the feed trough 5, the inner part of the rotating groove 37 The wall is fixedly connected with a motor 39 for driving the take-up wheel 38 to rotate; when the side wall of the conveyor belt is cut and trimmed, some of the waste materials cut off will be in the form of threads, which are relatively long and easy to get stuck in the feed end of the feed trough 5. At this time, the motor 39 can be started intermittently. When the motor 39 drives the take-up wheel 38 to rotate, the fixed line 42 is wound around the take-up wheel 38. At this time, the fixed line 42 will pull the dredging plate 43, so that the dredging plate 43 dredges the feed end of the feed trough 5, ensuring that the waste materials can be normally sucked into the feed trough 5. When the motor 39 is turned off, the elastic rope 36 will pull the dredging plate 43 to reset, thereby achieving the effect of reciprocating dredging.

[0042] like Figure 8 As shown, a conveyor belt trimming method, the method adopts the above-mentioned conveyor belt cutting and trimming equipment, and the method comprises the following steps:

[0043] S1: By moving the connecting plate 2 to the position where the conveyor belt is about to run, and then using the cooperation of the winding roller and the conveying roller, the conveyor belt passes between a pair of connecting blocks 3, and then the movement of the connecting block 3 can be controlled according to the width of the conveyor belt;

[0044] S2: The connecting block 3 moves, so that the rotating shaft 7 rotates, and the connecting rope 8 is wound around the rotating shaft 7, so that the connecting rope 8 pulls the connecting block 3 to move, so that the blade 6 contacts the side of the conveyor belt, and the blade 6 cuts and trims the protrusions and burrs on the side wall of the conveyor belt;

[0045] S3: When cutting and trimming the burrs, the driving blade 10 can be rotated at a high speed, so that the feed slot 5 generates suction to suck the waste into the connecting plate 2, and finally enters the hollow block 4 from the feed hole 11 and falls onto the filter screen 21;

[0046] S4: After the cutting is completed, the waste on the filter screen 21 can be allowed to enter the collection box 22 from the discharge slot 23. After the waste in the collection box 22 is full, the collection box 22 can be disassembled and the waste in the collection box 22 can be cleaned out.

[0047] Working principle: When the conveyor belt in the present application is being trimmed, the cooperation of the winding roller and the conveying roller can be used to allow the conveyor belt to pass between a pair of connecting blocks 3. At this time, the rotation of the rotating shaft 7 can be controlled according to the width of the conveyor belt, so that the connecting rope 8 is wound around the rotating shaft 7, so that the connecting rope 8 pulls the connecting block 3 to move, so that the blade 6 contacts the side of the conveyor belt. At this time, if there are burrs or protrusions on the side of the conveyor belt, they will be cut and trimmed by the blade 6, so as to achieve the effect of cutting and trimming conveyor belts of different widths. Workers can move the connecting block 3 to move the connecting block 3 to the side away from the conveyor belt, so as to keep the blade 6 away from the conveyor belt; the blade 6 in the present application will generate waste when cutting the burrs and protrusions of the conveyor belt, and the above-mentioned mechanism drives the blade 6 to contact the side of the conveyor belt through the driving mechanism. After the touch, the driving mechanism can be used to drive the connecting shaft 9 to rotate, so that the driving blade 10 rotates. At this time, the feed trough 5 will generate suction, thereby sucking the waste into the connecting plate 2, and finally entering the hollow block 4 from the feeding hole 11 to collect the waste generated during the cutting process; in the present application, when the rotating shaft 7 needs to be rotated, the connecting shaft 9 can be connected to the rotating shaft 7 by means of the clamping of the connecting rod 17 and the limiting groove 16. At this time, when the motor drives the connecting shaft 9 to rotate, it will drive the rotating shaft 7 to rotate. When only the connecting shaft 9 needs to drive the driving blade 10 to rotate at high speed, the first connecting plate 14 can be driven to move upward by means of the driving assembly, so that the connecting rod 17 is disengaged from the limiting groove 16. At this time, the motor can drive the connecting shaft 9 to rotate at high speed, so that the feeding end of the feed trough 5 generates suction;

[0048] When the connecting shaft 9 needs to rotate alone, the rotating rod 13 can be rotated so that the rotating rod 13 drives the second connecting disk 15 to rotate. At this time, the first magnetic block 18 will be aligned with the second magnetic block 19, thereby attracting the first connecting disk 14 to move upward, so that the connecting rod 17 is disengaged from the limiting groove 16. When the rotating shaft 7 and the connecting shaft 9 need to rotate together, the rotating rod 13 is rotated first so that the first magnetic block 18 and the second magnetic block 19 on the second connecting disk 15 are misaligned. At this time, the first spring will pull the first connecting disk 14 to move the limiting rod downward. Then, when the connecting shaft 9 rotates, the limiting rod 17 is disengaged from the limiting groove 16. The positioning groove 16 will be aligned with the connecting rod 17, so that the connecting rod 17 enters the limiting groove 16. At this time, when the connecting shaft 9 rotates, it will drive the rotating shaft 7 to rotate synchronously; after the waste in the present application is sucked into the hollow block 4, the waste will be filtered by the filter screen 21 to prevent the waste from being entangled on the driving leaf 10 and affecting the use of the driving leaf 10. When the driving leaf 10 generates suction, the waste will be adsorbed on the filter screen 21. When the driving leaf 10 stops rotating, the waste will slide on the inclined filter screen 21 and then enter the collection box 22 from the discharge trough 23 to be collected;

[0049] After the collection box 22 collects the waste, the suction force generated by the driving blade 10 during rotation can easily suck the waste in the collection box 22 from the discharge slot 23 to the hollow block 4. The discharge slot 23 can be sealed with the help of the sealing plate 28 through the above-mentioned mechanism. Then, when the driving blade 10 stops rotating, the sealing plate 28 can be moved upward with the help of the moving assembly so that the connecting slot 33 is connected to the discharge slot 23. At this time, the waste can enter the collection box 22 from the discharge slot 23. Then, the sealing plate 28 is driven downward by the moving mechanism to seal the discharge slot 23. When the sealing plate 28 needs to move upward to align the connecting slot 33 with the discharge slot 23, the electromagnet 41 can be started to make the electromagnet 41 suck the sealing plate 28 to move upward, thereby aligning the connecting slot 33 with the discharge slot 23, so that the waste on the filter screen 21 can be discharged into the collection box 22. When the sealing plate 28 no longer seals the discharge chute 23, the motor can drive the connecting shaft 9 to rotate at a low speed. At this time, the sliding rod 25 will move under the pull of the fourth spring, so that the driving block 26 corresponds to the pushing rod 27. At this time, when the driving block 26 passes through the pushing rod 27, the inclined surface of the driving block 26 will push the pushing rod 27, so that the pushing rod 27 drives the connecting frame 20 to shake, thereby causing the filter screen 21 to shake, so that the waste on the filter screen 21 can be better discharged into the collecting box 22.
