Description

Technical Field

[0001] This utility model belongs to the field of feeding technology for crushers, and specifically relates to a feeding device for a waste plastic crusher. Background Technology

[0002] Plastic products are ubiquitous in our daily lives and agricultural production. When these products reach the end of their lifespan or intended use, they are discarded and become waste plastics. Of course, the sources of waste plastics are not limited to this; waste or discarded products are generated at every stage of plastic synthesis, molding, processing, distribution, and consumption. Currently, in the process of recycling waste plastics, larger plastics need to be pre-cut into smaller pieces using a plastic shearing machine before being fed into the crusher. This is especially true for larger pallets, car bodies, plastic tables, or plastic buckets, etc., which require multiple shearing operations. Furthermore, round or short cylindrical plastics cannot be directly fed into the crusher because they are not easily caught by the crusher's teeth, causing them to accumulate at the feed inlet. Therefore, we have developed a feeding device for a waste plastic crusher to solve these technical problems. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a feeding device for a waste plastic crusher. It has a simple structure and is convenient and practical. The extrusion feeding device bites and presses round or strip plastics, so that the plastics are squeezed onto the crushing gears, thereby achieving the purpose of quickly crushing plastics and reducing the number of shearing processes of the plastic shearing machine.

Detailed Implementation

[0012] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0013] like Figures 1 to 2As shown; a feeding device for a waste plastic crusher includes a housing 1, a crushing device 2, an extrusion feeding device 3, a feed hopper 4, a transmission belt 5, and a power unit. The feed hopper 4 is connected to the housing 1. The crushing device 2 and the extrusion feeding device 3 are connected to the housing 1. Extrusion feeding devices 3 are respectively arranged on both sides of the crushing device 2. The power unit is driven by the crushing device 2. The crushing device 2 is driven by the extrusion feeding device 3 through two transmission belts 5. 2 includes a rotating roller 21, a large-tooth shearing group 22, a small-tooth shearing group 23, a small-tooth shearing cutter holder 24, and a cutter holder 25. The rotating roller 21 is movably connected inside the housing 1, with both ends penetrating the side walls of the housing 1 and connected to a power pulley. The power pulley is connected to a transmission belt 5. Several groups of large-tooth shearing groups 22 are arranged on the rotating roller 21, and several groups of small-tooth shearing groups 23 are arranged between adjacent large-tooth shearing groups 22. The small-tooth shearing groups 23 are arranged on the rotating roller 21. Two cutter holders 25 are respectively provided with... The housing 1, located on both sides of the rotating roller 21, has shearing grooves 26 that mate with the large-tooth shearing group 22. Several small-tooth shearing blade holders 24 are mounted on blade holders 25, and the small-tooth shearing blade holders 24 are arranged between adjacent small-tooth shearing groups 23. The extrusion feeding device 3 includes a drive pulley 31, a hinge rod 32, a pressing nozzle plate 33, a feeding sidewall 34, and a connecting strip 36. Two drive pulleys 31 are movably connected to the housing 1, and one end of each of the two hinge rods 32 is movably connected to the opposite sidewall. The feed sidewalls 34 are connected to the two sides of the housing 1. The feed sidewalls 34 are provided with a number of pressing nozzles 35. A number of pressing nozzles 33 are hinged at one end in the corresponding pressing nozzles 35 and connected to the connecting strip 36 at the other end. The pressing nozzles 33 are triangular and are arc-shaped on the side near the rotating roller 21 and the side near the feed hopper 4. The sidewalls of the pressing nozzles 33 are provided with a number of toothed grooves.

[0014] A power unit drives the rotating roller 21 to rotate, which in turn drives the large-tooth shearing assembly 22 and the small-tooth shearing assembly 23 to pulverize the plastic. Simultaneously, the rotation of the roller 21 drives the power pulleys at both ends, which in turn drive the transmission pulley 31 to rotate via the transmission belt 5. The rotation of the transmission pulley 31 causes one end of the hinge rod 32 to move eccentrically, while the other end of the hinge rod 32 drives the connecting strip 36 to move. The connecting strip 36 drives several pressure plates 33 to bite or press the plastic, forcing the plastic against the large-tooth shearing assembly 22 and the small-tooth shearing assembly 23, thus rapidly pulverizing the plastic. The nozzle plate 33 has convex and concave arc shapes on both sides. The convex arc shape matches the top of the nozzle plate opening 35 so that when the nozzle plate 33 presses the plastic, the plastic particles will not roll out through the nozzle plate opening 35 and leak. The gap between the nozzle plate opening 35 and the nozzle plate 33 needs to be controlled between 0.05mm and 0.15mm to prevent the plastic particles from leaking out. The concave arc end can effectively bite the round plastic to prevent the plastic from being squeezed out. At the same time, the tooth groove can prevent the plastic from slipping and failing to be crushed when it is crushed by the large tooth shearing group 22 and the small tooth shearing group 23.
