Description
Technical Field
[0001] This utility model relates to the field of crushing devices, and in particular to crushing devices for plastic products. Background Technology
[0002] With the increasing global awareness of environmental protection and the emphasis on resource recycling, the problem of plastic waste disposal has become increasingly prominent. Plastic product crushing equipment is an effective means to solve this problem. The equipment uses high-speed rotating blades to cut and tear waste plastic products, breaking them into smaller fragments for subsequent recycling.
[0003] In existing technologies, when crushing waste plastic products, the physical properties and resistance to breakage vary significantly due to differences in material, shape, thickness, and additives. When plastic products are fed into the crushing device, limitations in equipment design or operating parameters often make it difficult to achieve uniform and thorough crushing of all types of plastic products. Some harder or more complex plastic products may only be broken into larger fragments during the initial crushing process, far from meeting the fineness standards required for subsequent processing. These insufficiently crushed plastic products require secondary processing through additional crushing equipment or procedures in subsequent stages, which increases overall costs and reduces production efficiency. More problematic is that during the initial crushing process, plastic products of different sizes are often mixed together after crushing. Workers need to spend a lot of time and effort to effectively separate different types of plastic products through manual sieving or with the help of complex sorting equipment. This process further increases the workload of workers and seriously affects the efficiency of the overall crushing work. Therefore, it is necessary to improve the plastic product crushing device to solve the above problems. Utility Model Content
[0004] To overcome the problem that some plastic products, after being broken, are still too large to be directly processed, but when mixed with normal scrap, they require worker intervention for separation.
[0005] The technical solution of this utility model is as follows: a plastic product crushing device, including a device shell, a fixed bracket, and a crushing mechanism. A support leg for support is fixedly connected to the bottom of the device shell. A crushing mechanism for crushing is provided inside the device shell.

[0011] Preferably, both the first and second grinding wheels are provided with grinding teeth on their outer surfaces, and the grinding teeth are arranged alternately on the outer surfaces of the first and second grinding wheels.
[0012] The beneficial effects of this utility model are as follows: After screening by the screening plate body, larger plastic products are transported by the rotating auger for secondary crushing.

This avoids the problem that some plastic products are still too large to be directly processed after crushing, but are mixed with normal fragments and require manual intervention for separation.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1 - Figure 3This utility model provides an embodiment of a plastic product crushing device, including a device housing 1, a fixed support 21, and a crushing mechanism. A support leg 4 is fixedly connected to the bottom of the device housing 1. A crushing mechanism is installed inside the device housing 1. The fixed support 21 is fixedly connected inside the device housing 1. A connecting frame 22 is installed inside the device housing 1. A screening plate body 211 is fixedly connected inside the connecting frame 22. A first connecting rod 23 is fixedly connected to the outside of the connecting frame 22. A rolling wheel 24 is rotatably connected to the outside of the first connecting rod 23. The rolling wheel 24 is rotatably connected inside the fixed support 21. A first collecting hopper 25 is fixedly connected inside the device housing 1. A connecting... A first connecting pipe 27 is fixedly connected between the outer shell 26 and the first collecting hopper 25. A first motor 28 is fixedly connected inside the outer shell 26, and a pusher auger 29 is fixedly connected to the output end of the first motor 28. The pusher auger 29 is rotatably connected inside the outer shell 26. A first guide plate 210 is fixedly connected to the outside of the outer shell 26. During use, the crushing mechanism crushes the plastic products. After crushing, the plastic products fall into the fixed support 21 and are filtered by the screening plate body 211. Larger plastic products are blocked and then slide into the first collecting hopper 25. The plastic products enter the outer shell 26 through the first connecting pipe 27 and are then passed through the first motor 28. The device operates by rotating the auger 29, which pushes the plastic product upwards. After being discharged through a channel at the upper end of the connecting housing 26, it is guided by the first guide plate 210 and falls back into the crushing mechanism for secondary crushing. The connecting housing 26 has a rotating groove at a position relative to the auger 29. The auger 29 is rotatably connected inside the rotating groove, which restricts its rotation. The rotation of the auger 29 pushes larger plastic products upwards. A second motor 212 is fixedly connected to the outside of the device housing 1. A first rotating disk 213 is fixedly connected to the output end of the second motor 212. A first fixed rod 214 is fixedly connected to the outside of the first rotating disk 213. A first guide rod 214 is fixedly connected to the outside of the connecting frame 22. The first guide block 215 is slidably connected inside the device housing 1, and the first fixed rod 214 is slidably connected inside the first guide block 215. A second collecting hopper 216 is fixedly connected inside the device housing 1. A second motor 212 drives the first rotating disk 213 to rotate, and through the cooperation of the first fixed rod 214 and the first guide block 215, it drives the connecting frame 22 to reciprocate and vibrate, accelerating the screening of the crushed plastic products by the screening plate body 211. A groove is formed in the first guide block 215 at a position relative to the first fixed rod 214. The first fixed rod 214 is slidably connected inside the first guide block 215, and the groove restricts the sliding of the first fixed rod 214, preventing it from detaching from the first guide block 215.This affects the reciprocating vibration of the connecting frame 22.
[0021] Please see Figure 2 , Figure 4 - Figure 5 In this embodiment, the crushing mechanism includes a feed inlet 31, which is fixedly connected to the inside of the device housing 1. A second guide plate 32 is fixedly connected inside the feed inlet 31. A third motor 33 is fixedly connected inside the device housing 1. A first rotating rod 34 is fixedly connected to the output end of the third motor 33. A first bevel gear 35 is fixedly connected to the outside of the first rotating rod 34. A second bevel gear 36 meshes inside the first bevel gear 35. The second bevel gear 36 is rotatably connected to the outside of the feed inlet 31. The front of the second rotating rod 37 is fixedly connected to the outside. There is a second rotating disk 38, and a second fixing rod 39 is fixedly connected to the outside of the second rotating disk 38. A second guide block 310 is slidably connected inside the feed inlet 31. The second fixing rod 39 is slidably connected inside the second guide block 310. An extrusion plate body 311 is fixedly connected to the inside of the second guide block 310. The extrusion plate body 311 is slidably connected inside the feed inlet 31. A fixed inner shell 312 is fixedly connected inside the outer shell 1 of the device. A fourth motor 313 is fixedly connected inside the fixed inner shell 312. The output end of the fourth motor 313 is fixedly connected to... A first crushing wheel 314 is rotatably connected inside a fixed inner shell 312. A second gear 317 is fixedly connected to the outside of the first crushing wheel 314. A first gear 316 meshes with the outside of the second gear 317. A second crushing wheel 315 is fixedly connected inside the first gear 316. The second crushing wheel 315 is rotatably connected inside the fixed inner shell 312. Through the cooperation of a second guide block 310 and a second fixed rod 39, it drives the extrusion plate body 311 to extrude plastic products, thereby further improving the efficiency of the crushing operation. The second guide block 310 has a groove at the relative position of the second fixed rod 39. The second fixed rod 39 is slidably connected inside the groove. The groove restricts the sliding of the second fixed rod 39 and prevents the second fixed rod 39 from disengaging from the second guide block 310. Both the first crushing wheel 314 and the second crushing wheel 315 are provided with crushing teeth on their outer surfaces. The crushing teeth are arranged alternately on the outer surfaces of the first crushing wheel 314 and the second crushing wheel 315. The alternating crushing teeth crush the plastic product, thereby reducing the volume of the plastic product for subsequent processing.
[0022] During operation, the plastic product is poured into the feed inlet 31 and guided by the second guide plate 32 to fall onto the extrusion plate body 311. The third motor 33 drives the first rotating rod 34 to rotate, which in turn drives the first bevel gears 35 on both sides to rotate synchronously. The first bevel gears 35 then drive the second bevel gear 36, which in turn drives the second rotating rod 37. The second rotating rod 37 then drives the second rotating disk 38. The second rotating disk 38, through the second fixed rod 39 and the second guide block 310, causes the extrusion plate bodies 311 on both sides to slide mirror-like, thus initially extruding the plastic product. The extruded plastic product continues to fall and enters the inner fixed shell 312. At this point, the fourth motor 313 drives the first crushing wheel 314 to rotate. The rotation of the first crushing wheel 314 drives the second gear 317 to engage with the first gear 316, which in turn drives the second crushing wheel 315 to rotate. The plastic products are crushed and fall into the connecting frame 22. The second motor 212 drives the first rotating disk 213 to rotate. When the first rotating disk 213 rotates, it cooperates with the first fixed rod 214 and the first guide block 215. The first connecting rod 23 rolls outside the fixed bracket 21 to support the connecting frame 22 and drive the connecting frame 22 to sway back and forth. When the connecting frame 22 sways, the crushed plastic products are screened by the screening plate body 211. The qualified plastic products fall through the screening plate body 211 into the second collection hopper 216 and are discharged. The unqualified plastic products slide to the first collection hopper 25 and enter the connecting shell 26 through the first connecting pipe 27. The first motor 28 drives the pusher auger 29 to rotate, thereby pushing the unqualified plastic products upward. After being discharged through the through hole at the top of the connecting shell 26, they are guided by the first guide plate 210 and fall into the feed inlet 31 for secondary crushing.
[0023] Through the above steps, after screening by the screening plate body 211, larger plastic products are transported by the push auger 29 for secondary crushing. This solves the problem that some plastic products are still too large to be directly processed after crushing, but need to be separated by staff when mixed with normal crushed materials.
