Description

Technical Field

[0001] This utility model relates to the field of plastic pellet sorting technology, specifically to a plastic pellet processing and sorting device. Background Technology

[0002] Plastic particles, also known as plastic granules, are raw materials used to store, transport, and process plastics in a semi-finished form. Plastics are a type of polymer material. They can be made from petroleum as a raw material, such as ethylene, propylene, vinyl chloride, and styrene. The molecules of these substances can react with each other under certain conditions to form compounds with very large molecular weights, i.e., polymers.

[0003] According to patent document CN218875979U, a plastic particle processing and sorting device is disclosed, which relates to the field of plastic particle auxiliary sorting. It includes a feeding seat, a sorting seat is assembled on the bottom side of the feeding seat, and an upper sorting panel is provided in the sorting seat; the upper sorting panel is fixedly fitted on the top side of the inner side of the sorting seat, and a lower sorting panel is movably fitted in the sorting seat. A side groove adapted to the specifications of the lower sorting panel is opened on the side wall of the sorting seat, and a cylinder seat is assembled on the outer wall of the sorting seat.

[0004] Traditional plastic pellet processing and sorting equipment mostly adopts simple screening structures or manual sorting methods. However, due to factors such as temperature and humidity changes and mutual compression during production, storage and transportation, plastic pellets are prone to sticking together. Traditional equipment is difficult to effectively disperse the sticking plastic pellets, which not only affects the sorting accuracy but also causes screen blockage and reduces production efficiency. At the same time, existing feeding mechanisms are mostly gravity feeding or rough mechanical pushing feeding, which cannot accurately control the feeding speed. When a large number of plastic pellets are fed at the same time, material accumulation is likely to occur, resulting in excessive local load on the sorting equipment and even causing equipment failure. Utility Model Content

At the same time, the existing feeding mechanism is mostly gravity feeding or coarse mechanical pushing feeding, which cannot accurately control the feeding speed. When a large number of plastic pellets are fed at the same time, material accumulation is likely to occur, resulting in excessive local load on the sorting equipment and even causing equipment failure.

The rotating shaft 205 drives the first bevel gear 208 to rotate. 208 drives the second bevel gear 209 to rotate, and the second bevel gear 209 drives the auger 210 to rotate, thereby causing the material to fall at a uniform speed to the top of the screen plate 301, and then roll on the top of the screen plate 301, thus performing sorting work; support columns are fixedly connected to the four corners of the bottom of the material box 201, and the bottom of the support columns is fixedly connected to the shell 1. By setting the support columns, the operation of the material box 201 is stabilized and the material box 201 is supported; synchronous pulleys 206 are fixedly connected to the front of the dispersing roller 203 and the rotating shaft 205, and synchronous belts 207 are meshed on the surface of the synchronous pulleys 206. By setting the synchronous pulleys 206 and synchronous belts 207, the material is sorted. 07.

[0025] Working principle: By setting up the material guiding mechanism 2, the material is placed in the inner cavity of the material box 201. The motor 202 is started by the external controller. The motor 202 drives the dispersing roller 203 to rotate, which breaks up the lumpy material. Then the material enters the inner cavity of the discharge pipe 211 through the guide pipe 212. During the operation of the dispersing roller 203, it also drives the rotating shaft 205 to rotate. The rotating shaft 205 drives the first bevel gear 208 to rotate.
