Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a crusher for waste plastic buckets. Background Technology

[0002] Waste plastic drum crushers are mechanical devices specifically designed for processing waste plastic drums (such as PE water drums, chemical ton drums, etc.). They crush large-volume plastic drums into small particles or fragments through specific methods, facilitating subsequent recycling, regeneration, or safe disposal. By crushing, the volume of plastic drums is reduced, making them easier to transport, store, or further process. Furthermore, the crushed plastic fragments can be used as recycled raw materials to produce new plastic products, thereby improving resource utilization.

[0003] Patent document CN216732552U discloses a plastic bucket crusher that facilitates the disassembly and assembly of the screen. It discloses that "to address the problem of inconvenient screen disassembly, the following technical solution is provided, including a machine housing, a cutter roller rotatably connected to the machine housing, a hopper connected to the machine housing, a conveying component connected to the hopper for transporting plastic buckets, a screen frame rotatably connected to the machine housing and located below the cutter roller, and a hydraulic cylinder connected to the machine housing for driving the screen frame to rotate. The screen is installed on the screen frame, and a pick-and-place port for replacing the screen is opened on the machine housing. Two screens are provided and pass through the pick-and-place port in sequence as the screen frame rotates. The hydraulic cylinder can drive the screen frame to rotate, and as the screen frame rotates, the screen can pass through the pick-and-place port in sequence, which facilitates the operator to disassemble and replace the screen at the pick-and-place port."

[0004] However, the plastic bucket crushers in the aforementioned publicly available literature that facilitate screen disassembly and replacement mainly consider the convenience for operators to disassemble and replace the screen at the loading and unloading port, but do not facilitate the screening of the crushed material.

[0005] Therefore, it is necessary to develop a classification mechanism that can screen the crushed materials. Utility Model Content

[0006] The purpose of this utility model is to provide a waste plastic bucket crusher to solve the technical problem mentioned in the background art of enabling the waste plastic bucket crusher to have a screening function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crusher for waste plastic buckets, comprising: a crusher body and a discharge port, wherein the outer wall of the crusher body is provided with a sorting mechanism for screening the crushed material;

[0008] The sorting mechanism includes an L-shaped frame, a screening frame, and a screening box. The L-shaped frame is located on the outer wall of the crusher body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a classification mechanism to screen crushed materials. Existing crushers often produce particles of varying sizes after crushing, necessitating improvement. Based on existing knowledge, when injection molding plastic granules, the mesh size is typically 8-12mm, requiring a 12mm coarse screen. For blow molding, the mesh size is typically 4-6mm, requiring a 6mm fine screen. The screening box is then placed below the screening frame, and the material is then... Once the connecting screw is fixed in the connecting screw groove, the screening box and screening frame are assembled. Then, the bottom of the screening box is placed on the rubber pad on the L-shaped frame from top to bottom. The screening box and screening frame are located on one side of the discharge port. Larger particles are located on the coarse screening screen of the screening frame. When the particles are <12mm, they enter the fine screening screen in the screening box. The particles located below the fine screening screen are <6mm. The crushed particles are screened sequentially according to their size, which makes it easier to determine the subsequent use based on the different particle sizes.

[0017] 2. This utility model uses a dust-suppressing mechanism to adsorb dust after material discharge. When materials are crushed and discharged, dust often flies around, so this needs to be improved. The dust-suppressing box can be moved up and down via an electric sliding rail. The purpose is to avoid affecting the placement of the screening box and screening frame on the L-shaped frame. The filter frame is located on one side of the assembly plate, and the assembly screw is fixed into the assembly screw groove. The filter frame is then installed at the bottom of the dust-suppressing box. Subsequently, the adsorption fan works to adsorb the flying dust, which is then filtered through the activated carbon plate and finally discharged through the ventilation groove, thus adsorbing and treating the dust.

A fixed wheel 6 is installed on the inner wall of the crusher body 1. A discharge inclined plate 7 is installed on the inner wall of the crusher body 1. The discharge port 8 is provided on the inner wall of the crusher body 1. First, the plastic bucket is added into the crusher body 1 through the feed frame 2. Then, the crushing motor 4 drives the driving wheel 5 to rotate. The plastic bucket is crushed by high-speed shearing force through the gap between the driving wheel 5 and the fixed wheel 6 and discharged through the discharge inclined plate 7 and the discharge port 8.

[0029] Please see Figure 2 , Figure 3 and Figure 4 The outer wall of the crusher body 1 is equipped with a sorting mechanism for screening the crushed material. The sorting mechanism includes an L-shaped frame 9, a screening frame 12, and a screening box 11. The L-shaped frame 9 is located on the outer wall of the crusher body 1. A rubber pad 10 is installed on the top of the L-shaped frame 9. The screening box 11 is located on the top of the L-shaped frame 9, and the screening frame 12 is located on the top of the screening box 11. A fine screening screen 13 is installed on the inner wall of the screening box 11, and a coarse screening screen 14 is installed on the inner wall of the screening frame 12. A connecting plate 15 is installed on the outer wall of the screening frame 12, and a connecting screw groove 16 is provided on the outer wall of the screening box 11. A connecting screw 17 is installed on the outer wall of the connecting plate 15, and one end of the connecting screw 17 extends into the interior of the connecting screw groove 16. Currently, the existing crusher body 1 often produces particles of varying sizes after crushing the material, thus requiring improvement. Based on existing knowledge, if plastic... When the granules are used for injection molding, the mesh size is usually 8-12mm, so the coarse screening screen 14 has a mesh size of 12mm. If used for blow molding, the mesh size is usually 4-6mm, so the fine screening screen 13 has a mesh size of 6mm. Then, the screening box 11 is placed below the screening frame 12 and then fixed in the connecting screw groove 16 by the connecting screw 17. The screening box 11 and the screening frame 12 are then assembled. Then, the bottom of the screening box 11 is placed on the rubber pad 10 on the L-shaped frame 9 from top to bottom. The screening box 11 and the screening frame 12 are located on one side of the discharge port 8. The larger granules are located on the coarse screening screen 14 of the screening frame 12. When the granules are <12mm, they enter the fine screening screen 13 in the screening box 11. The granules located below the fine screening screen 13 are <6mm. The crushed granules are screened sequentially according to their size to facilitate the determination of their subsequent use based on their size.

[0030] Please see Figure 1 , Figure 5 and Figure 6The outer wall of the crusher body 1 is equipped with a dust suppression mechanism for adsorbing dust after discharge. The dust suppression mechanism includes a dust suppression box 19. An electric slide rail 18 is embedded in the outer wall of the crusher body 1. The dust suppression box 19 is installed at the output end of the electric slide rail 18. The inner wall of the dust suppression box 19 is provided with a ventilation groove 20. An adsorption fan 21 is installed on the inner wall of the dust suppression box 19. A filter frame 22 is installed at the bottom of the dust suppression box 19.

An assembly plate 25 is installed on the outer wall of the dust suppression box 19. An assembly screw 26 is installed on the outer wall of the assembly plate 25. One end of 26 extends into the interior of the assembly screw groove 24. When the material is crushed and discharged, dust often flies up. Therefore, this needs to be improved. The dust collection box 19 can be moved up and down by the electric slide rail 18. The purpose is to avoid affecting the placement of the screening box 11 and the screening frame 12 on the L-shaped frame 9. The filter frame 22 is located on one side of the assembly plate 25. The assembly screw 26 is fixed in the assembly screw groove 24. Then the filter frame 22 is installed at the bottom of the dust collection box 19. Then the adsorption fan 21 works to adsorb the flying dust and filter it through the activated carbon plate 23. Finally, it is discharged through the ventilation groove 20, thereby adsorbing and treating the dust.

[0031] The working principle is as follows: First, the plastic bucket is added into the crusher body 1 through the feed frame 2. Then, the crushing motor 4 drives the rotating wheel 5 to rotate. Utilizing the gap between the rotating wheel 5 and the fixed wheel 6, the plastic bucket is crushed by high-speed shearing force and discharged through the discharge inclined plate 7 and the discharge port 8. Currently, the crusher body 1 often produces particles of varying sizes after crushing, so improvements are needed. Based on existing knowledge, when plastic granules are used for injection molding, the mesh size is typically 8-12mm, so the coarse screening screen 14 has a 12mm aperture. If used for blow molding, the mesh size is typically 4-6mm, so the fine screening screen 13 has a 6mm aperture. Then, the screening box 11 is placed below the screening frame 12 and fixed in the connecting screw groove 16 by the connecting screw 17. The screening box 11 and the screening frame 12 are then assembled. Finally, the bottom of the screening box 11 is placed on the rubber pad 10 on the L-shaped frame 9 from top to bottom. 12 is located on one side of the discharge port 8. Larger particles are located on the coarse screening screen 14 of the screening frame 12. When the particle size is <12mm, the particle enters the fine screening screen 13 in the screening box 11. The particles below the fine screening screen 13 are <6mm. The crushed particles are screened sequentially according to their size to facilitate the determination of their subsequent use based on their size. When the material is discharged after crushing, dust often flies up. Therefore, this needs to be improved. The dust collection box 19 can be moved up and down by the electric slide rail 18. The purpose is to avoid affecting the placement of the screening box 11 and the screening frame 12 on the L-shaped frame 9. The filter frame 22 is located on one side of the assembly plate 25. The assembly screw 26 is fixed in the assembly screw groove 24. The filter frame 22 is installed at the bottom of the dust collection box 19. Then the adsorption fan 21 works to adsorb the flying dust and filter it through the activated carbon plate 23. Finally, it is discharged through the ventilation groove 20, thus adsorbing and treating the dust.
