Description

Technical Field

[0001] This utility model relates to the field of PVC plastic granule crushing technology, specifically a crushing device for PVC plastic granule processing. Background Technology

[0002] Polyvinyl chloride (PVC) is the world's third-largest synthetic polymer plastic produced, with an annual output of approximately 40 million tons. PVC is a polymer formed by the free radical polymerization of PVC monomers through initiators such as peroxides, monoterpenes, or other initiators, or under the influence of light and heat. During the production and processing of PVC plastic granules, they usually need to be crushed. When using crushing equipment to crush the raw materials, a set of crushing rollers is usually used. However, a single crushing device is not enough to thoroughly crush the PVC raw materials, and some larger PVC materials are not crushed again, which reduces the efficiency of subsequent melting and plasticizing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a crushing device for processing PVC plastic granules, which solves the problems mentioned in the background art.

A second motor is fixedly installed on one side of the device box, and the output end of the second motor is fixedly connected to the rotating circular block via a coupling. A fixed block is fixedly installed inside the groove, and two compression springs are fixedly installed at the bottom of the fixed block. One end of the two compression springs is connected to a movable block, which contacts the rotating circular block and is slidably connected to the groove. Two movable shafts are fixedly installed on the top of the movable block, and one end of each movable shaft extends through the compression spring to the outside of the fixed block and is fixedly connected to a filter screen plate. Both movable shafts are slidably connected to the fixed block. One side of the filter screen plate is rotatably connected to the device box via a hinge structure. A mating groove is provided on one side of the device box, and the mating groove mates with the filter screen plate.

[0005] Preferably, a mounting box is fixedly installed on one side of the device housing. Two rotating shafts are rotatably connected inside the device housing.

A first motor is fixedly installed on one side of the mounting box. The output end of the first motor is fixedly connected to the rotating shaft via a coupling. Several gears mesh with each other. Starting the first motor causes one of the gears and the rotating shaft to rotate. By utilizing the meshing of the gears, the two crushing rollers rotate simultaneously, thereby achieving the purpose of crushing plastic.

[0006] Preferably, a guide plate is fixedly installed inside the device box, a discharge box is fixedly installed on one side of the device box, a connecting plate is fixedly installed on one side of the device box, two mounting brackets are fixedly installed on the top of the connecting plate and on one side of the device box, an auger is fixedly connected between the two mounting brackets, the auger is fixedly connected to the discharge box, and a guide frame is fixedly installed on one side of the auger. The screened plastic particles roll down the surface of the guide plate into the discharge box through the guide plate, and then roll into the auger through the discharge box. The auger then transports the plastic particles back into the device box, thereby improving the crushing effect of the device on plastic particles.

[0007] Preferably, a baffle is fixedly installed on the top of the filter plate. The baffle contacts one side of the inner cavity of the device box. Through the baffle, some plastic particles placed there are elastic and splash to the outside of the device box after falling through the matching groove, thus avoiding waste.

One end of each rotating shaft 32 extends through the device housing 1 into the interior of the mounting box 3 and is fixedly connected to a gear 33. A rotating shaft 34 is rotatably connected inside the mounting box 3. The outer side of the rotating shaft 34 is fixedly connected to the gear 33. A first motor 2 is fixedly installed on one side of the mounting box 3. The output end of the first motor 2 is fixedly connected to the rotating shaft 34 via a coupling. Several gears 33 mesh with each other. When the first motor 2 is started, one of the gears 33 and the rotating shaft 34 rotate. By utilizing the meshing of the gears 33, the two crushing rollers 22 rotate simultaneously, thereby achieving the purpose of crushing plastic.

[0024] A guide plate 18 is fixedly installed inside the device box 1. A discharge box 9 is fixedly installed on one side of the device box 1. A connecting plate 8 is fixedly installed on one side of the device box 1. Two mounting brackets 13 are fixedly installed on the top of the connecting plate 8 and on one side of the device box 1. An auger 11 is fixedly connected between the two mounting brackets 13. The auger 11 is fixedly connected to the discharge box 9. A guide frame 14 is fixedly installed on one side of the auger 11. The screened plastic particles roll down the surface of the guide plate 18 into the discharge box 9 through the guide plate 18, and then roll into the auger 11 through the discharge box 9. The auger 11 can then transport the plastic particles back into the device box 1, thereby improving the crushing effect of the device on plastic particles.

[0025] A baffle 21 is fixedly installed on the top of the filter plate 19. The baffle 21 contacts one side of the inner cavity of the device box 1. Through the baffle 21, some plastic particles placed there are elastic and splash to the outside of the device box 1 through the matching groove 25 after falling, thus avoiding waste.

[0026] The top of the device box 1 is provided with a feeding groove 24, and a feeding hopper 16 is fixedly installed on the top of the device box 1. The feeding hopper 16 cooperates with the feeding groove 24. Support columns 20 are fixedly installed at the bottom of both the device box 1 and the connecting plate 8. The entire device can be supported by several support columns 20.

[0027] The device box 1 has a discharge trough 23 on one side and a collection frame 5 fixedly installed on one side. A collection box 4 is slidably connected inside the collection frame 5. The collection box 4 cooperates with the discharge trough 23. Through the cooperation of the collection box 4 and the discharge trough 23, the purpose of collecting the plastic particles after the first crushing is achieved.

A control panel 15 is provided on one side of one of the device doors 7. The control panel 15 is electrically connected to both the first motor 2 and the second motor 10. The electrical connection between the control panel 15 and the first motor 2 and the second motor 10 facilitates the worker's control of the first motor 2 and the second motor 10 during use.

[0029] In summary, this PVC plastic granule processing crushing device allows the worker to start the first motor 2 by pressing a button on the control panel 15. This causes the rotating shaft 34 and one of the gears 33 to rotate. The meshing of the gears 33 further rotates the two rotating shafts 32 and the two crushing rollers 22. The interaction between the two crushing rollers 22 achieves the purpose of crushing the PVC plastic granules. Simultaneously, the auger 11 is activated, followed by the second motor 10, causing the rotating block 30 to rotate. The rotating block 30 interacts with the movable block 29, causing the movable block 29 to move up and down, thereby moving the filter plate 19 within the device housing. 1. Moving up and down, the worker feeds PVC plastic granules into the device box 1 through the feed chute 24. During the pouring process, the PVC plastic granules pass between the two crushing rollers 22 and fall onto the surface of the filter screen 19. The crushed PVC plastic granules are screened by the vibration of the filter screen 19. The PVC plastic granules that pass through the holes of the filter screen 19 fall onto the surface of the guide plate 18 and roll down the surface of the guide plate 18 into the discharge box 9. They then roll down into the auger 11 and are transported by the auger 11 to the inside of the guide frame 14. The guide frame 14 then rolls the PVC plastic granules back into the device box 1 for further crushing.
