Description

Technical Field

[0001] This utility model relates to the technical field of plastic product recycling, and in particular to a shredder with a feeding structure. Background Technology

[0002] As a key piece of equipment for solid waste treatment and resource utilization, the technological evolution of shredders deeply aligns with the needs of the circular economy and environmental protection strategies. With the acceleration of urbanization and the expansion of industrial production, large quantities of difficult-to-process materials such as waste metals, plastics, rubber, and wood urgently require efficient reduction and disposal. Traditional compaction and landfill methods are no longer sufficient to meet the requirements of green development. Modern shredders, through modular blade design, variable cross-section shearing technology, and intelligent load sensing systems, achieve precise tearing and size control of materials of different materials. Their core lies in the multi-axis linkage shearing-tearing composite action mechanism, combined with a hydraulically driven automatic reverse anti-clogging function, significantly improving processing efficiency and equipment adaptability. This technology is widely used in pre-treatment before waste incineration, recycling of renewable resources, and harmless treatment of hazardous waste, and has become an important node in the closed-loop flow of materials in the construction of "zero-waste cities."

[0003] However, when plastic fiber products (such as plastic woven bags, fishing nets, and transparent plastic bags) are put into the hopper, the plastic fiber products will expand inside the hopper, making them easy to get stuck inside the hopper and unable to be discharged, thus affecting the shredding efficiency.

[0023] Example 1

[0024] Reference Figure 1 This is the first embodiment of the present invention, which provides a shredding mechanism 100 to shred plastic fiber products.

[0025] The shredding mechanism 100 includes a workbench 101, a shredder 102 fixedly connected to the top of the workbench 101, and a feeding hopper 103 fixedly connected to the top of the shredder 102.

[0026] Specifically, starting the shredder 102 drives the internal shredding toothed roller to shred the plastic fiber products.

[0027] Furthermore, when it is necessary to feed and shred plastic fiber products, the plastic fiber products are placed into the feeding hopper 103, and then the shredder 102 is started to drive the internal shredding toothed roller to shred the plastic fiber products.

[0028] Example 2

[0029] Reference Figures 1-3 In the second embodiment of this utility model, an anti-blocking mechanism 200 is provided to realize the extrusion feeding of plastic fiber products.

[0030] The anti-blocking mechanism 200 includes a hydraulic rod 201. The bottom of the inner side of the hydraulic rod 201 is fixedly connected to the bottom of both sides of the feeding hopper 103. A movable plate 202 is provided on the top of the feeding hopper 103. A lower pressure plate 203 is fixedly connected to the bottom of the movable plate 202. Three lower pressure plates 203 are provided and evenly distributed. The two sides of the bottom of the movable plate 202 are fixedly connected to the piston end of the hydraulic rod 201. Limiting components 204 are fixedly connected to the four corners of the top of the feeding hopper 103. The limiting components 204 include limiting rods 204a. The bottom of the limiting rods 204a is fixedly connected to the four corners of the top of the feeding hopper 103. Limiting grooves 204b are provided at the four corners of the bottom of the lower pressure plate 203. The inner wall of the limiting groove 204b is slidably connected to the surface of the limiting rod 204a. A limiting piece 204c is fixedly connected to the top of rod 204a. A meshing groove 205 is provided at the bottom of the lower pressure plate 203. Several meshing grooves 205 are provided and are evenly distributed. A telescopic sleeve 206 is fitted on the top of the surface of the hydraulic rod 201. The top of the telescopic sleeve 206 is fixedly connected to both sides of the bottom of the lower pressure plate 203. A clearing rod 207 is slidably connected inside the meshing groove 205. Movable rods 208 are provided on the front and rear sides of the lower pressure plate 203. The inner side of the movable rod 208 is fixedly connected to the clearing rod 207. Guide rods 209 are fixedly connected to both sides of the front and rear sides of the top of the hopper 103. The top of the guide rod 209 extends through to the top of the movable rod 208 and is slidably connected to the movable rod 208. A spring 210 is fitted on the surface of the guide rod 209.

[0031] Specifically, by slowly moving the lower pressure plate 203 downwards, the lower pressure plate 203 will push the plastic fiber products that are stuck in the feed hopper 103 due to expansion and cannot be discharged downwards, so that the plastic fiber products can contact the shredding tooth roller inside the shredder 102, thereby shredding the plastic fiber products and avoiding the blockage of plastic fiber products.

[0032] Furthermore, when the shredder 102 is started, the synchronously activated hydraulic rod 201 drives the lower pressure plate 203 to move slowly downwards via the movable plate 202. The lower pressure plate 203 then pushes down the plastic fiber products that are stuck in the feed hopper 103 due to expansion, allowing them to contact the shredding rollers inside the shredder 102 and thus shred them. Simultaneously, the meshing groove 205 prevents the shredding rollers inside the shredder 102 from damaging the lower pressure plate 203. If some plastic fiber products become stuck in the meshing groove 205 during use, the movable rod 208 can be pulled along the path on the surface of the guide rod 209. The downward movement causes the movable rod 208 to drive the unblocking rod 207 to scrape out some of the plastic fiber products stuck in the meshing groove 205 and fall into the shredder 102 for shredding. Then, the elastic force of the spring 210 pushes the movable rod 208 to drive the unblocking rod 207 to reset. During the use of the hydraulic rod 201, the telescopic sleeve 206 can protect the surface of the piston rod of the hydraulic rod 201 to prevent foreign objects from adhering and affecting the driving of the hydraulic rod 201. During the movement of the movable plate 202, the sliding cooperation between the limiting rod 204a and the limiting groove 204b can ensure the stability of the movement of the movable plate 202. At the same time, the limiting piece 204c can limit the maximum movement space of the movable plate 202.

[0033] The remaining structure is the same as that in Example 1.

[0034] Example 3

[0035] Reference Figures 1-3 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that this embodiment provides a shredder with a feeding structure.

[0036] When it is necessary to feed and shred plastic fiber products, the plastic fiber products are placed into the feeding hopper 103, and then the shredder 102 is started to drive the internal shredding toothed roller to shred the plastic fiber products.

[0037] When the shredder 102 is started, the synchronously activated hydraulic rod 201 drives the lower pressure plate 203 to move slowly downwards via the movable plate 202. The lower pressure plate 203 then pushes down the plastic fiber products that are stuck in the feed hopper 103 due to expansion, allowing them to contact the shredding rollers inside the shredder 102 and be shredded. Simultaneously, the meshing groove 205 prevents the shredding rollers from damaging the lower pressure plate 203. If some plastic fiber products become stuck in the meshing groove 205 during use, the movable rod 208 can be pulled downwards along the path on the guide rod 209. This causes the movable rod 208 to drive the unblocking rod 207 to scrape out some of the plastic fiber products stuck in the meshing groove 205 and fall into the shredder 102 for shredding. Then, the elastic force of the spring 210 pushes the movable rod 208 to drive the unblocking rod 207 to reset. During the use of the hydraulic rod 201, the telescopic sleeve 206 can protect the surface of the piston rod of the hydraulic rod 201 to prevent foreign objects from adhering and affecting the driving of the hydraulic rod 201. In addition, during the movement of the movable plate 202, the sliding cooperation between the limiting rod 204a and the limiting groove 204b can ensure the stability of the movement of the movable plate 202. At the same time, the limiting piece 204c can limit the maximum movement space of the movable plate 202.

[0038] In summary, the shredding mechanism 100 is activated to shred the plastic fiber products. During the shredding process, the anti-blocking mechanism 200 continuously presses down on the plastic fiber products, ensuring that the plastic fiber products can contact the teeth of the shredding roller in a timely manner and shred the soft plastic fiber products, thus preventing blockage.
