Description

Technical Field

[0001] This utility model relates to the field of plastic recycling and cleaning technology, specifically a pretreatment device for recycling and cleaning waste plastics. Background Technology

[0002] Against the backdrop of global advocacy for green and sustainable development, plastic recycling has become an important measure to address "white pollution" and conserve resources. As a core component of plastic recycling and cleaning equipment, the sorting mechanism plays a crucial role in separating different types and properties of plastics. Its sorting efficiency directly affects the efficiency of subsequent cleaning and recycling processes and the quality of the products.

[0003] The prior art discloses a waste plastic recycling and pretreatment equipment with announcement number CN220763198U, which includes a cleaning tank. The top of the cleaning tank is integrally equipped with lifting brackets on the middle of opposite sides. There are two lifting brackets. The two lifting brackets are equipped with lifting mechanisms on the side of the two lifting brackets that are close to each other. The lower ends of the lifting mechanisms are located on opposite sides of the cleaning tank. The cleaning tank is equipped with a cleaning tank. A cleaning mechanism is provided on one side of the cleaning tank. A connecting seat is provided on the other side of the cleaning tank. The cleaning mechanism and the connecting seat are both connected to the lifting mechanism. The top of the two lifting brackets is equipped with a cleaning pipe through a frame. The bottom of the cleaning pipe is equipped with several flushing nozzles.

[0004] The aforementioned pretreatment equipment for recycling and cleaning waste plastics has a series of structures that integrate soaking and rinsing functions. The water used for soaking and rinsing is recycled, which is energy-saving and environmentally friendly. The agitation of the plastic in the cleaning tank makes it easy for impurities to fall off, resulting in uniform and thorough cleaning. It is also convenient to lift and rotate the cleaning tank for discharge. However, the angle of the sorting mechanism is not adjustable, which makes it unsuitable for plastic particles of different shapes and densities. As a result, the equipment is not effective in use and needs to be improved. Utility Model Content

A bearing 402 is fixedly connected to the left side of the guide frame 401, and a connecting shaft 403 is fixedly connected to the inner ring of the bearing 402. A sorting plate 404 is fixedly connected to the surface of the connecting shaft 403. A stepper motor 405 is fixedly connected to the top of the guide frame 401, and a rotating shaft 407 is fixedly connected to the output shaft of the stepper motor 405. A gear 406 is fixedly connected to the surface of the rotating shaft 407. The guide frame 401 has a fixedly connected limit seat 409 on the right side inside. The limit seat 409 has a slidably connected rack 408 inside. The gear 406 meshes with the rack 408. The bottom of the sorting plate 404 has a fixedly connected spring 410. The end of the spring 410 away from the sorting plate 404 is fixedly connected to the top of the guide frame 401. The guide frame 401 has a through groove on the left side. The diameter of the through groove is adapted to the diameter of the connecting shaft 403. The thickness of the rack 408 is adapted to the distance between the upper and lower ends inside the limit seat 409.

[0026] The cleaning assembly 3 includes a connecting plate 301, a cleaning fluid storage tank 302, a connecting pipe 303, an intermediate storage tank 304, a connecting box 305, a liquid outlet 306, a plastic inlet box 307, a magnetic sealing plate 308, a magnetic strip 309, and a discharge end 310. The connecting plate 301 is fixedly connected to the top of the processing table 1. The cleaning fluid storage tank 302 is fixedly connected to the top left side of the connecting plate 301. The connecting pipe 303 is fixedly connected to the top of the cleaning fluid storage tank 302. The connecting box 305 is fixedly connected to the right side of the cleaning fluid storage tank 302. The intermediate storage tank 304 is fixedly connected to the inside left side of the box 305. The end of the connecting pipe 303 away from the cleaning fluid storage tank 302 is fixedly connected to the top of the intermediate storage tank 304. The liquid outlet 306 is fixedly connected to the bottom of the intermediate storage tank 304. The plastic inlet box 307 is fixedly connected to the inside right side of the connecting box 305. The magnetic strip 309 is fixedly connected to the top of the plastic inlet box 307. The discharge end 310 is fixedly connected to the bottom of the plastic inlet box 307. The top of the plastic inlet box 307 has a feeding opening. The area of ​​the magnetic sealing plate 308 is larger than the area of ​​the feeding opening. The magnetic sealing plate 308 can seal the top when no material is being fed, controlling the amount of material fed at one time and preventing impurities from entering, which is convenient for subsequent sorting.

Before pouring, the magnetic sealing plate 308 needs to be held and slid forward to separate it from the top of the plastic inlet box 307, exposing the top feed opening slot. Then the plastic can be poured in and placed on top of the guide frame 401 using the discharge end 310 for sorting. A cleaning component is provided on the left side. The cleaning fluid can be delivered into the inner wall of the intermediate storage tank 304 through the cleaning fluid storage tank 302, connecting pipe 303, and internal pump. The cleaning fluid then flows out through the outlet end 306 to aid in cleaning, thus completing the feeding step. The equipment cleaning process after processing requires the use of sorting component 4 during sorting. Sorting can be performed using sorting plate 404. The angle of sorting plate 404 can be adjusted as needed. During adjustment, stepper motor 405 can be activated to drive gear 406 to rotate, which in turn drives rack 408, which meshes with gear 406, to slide forward or backward inside limit seat 409. Sliding forward makes the tilt angle of sorting plate 404 smaller, and sliding backward makes the tilt angle larger until it approaches a vertical state. With the help of spring 410, the adjustment rate can be controlled during angle adjustment, enabling sorting processing. The angle of the flexible sorting plate is adjustable, which can adapt to plastic particles of different shapes and densities.
