Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a screening device for processing plastic products. Background Technology

[0002] With the widespread application of plastic products in daily life, construction, packaging, automobiles, and many other fields, the demand for plastic products continues to grow significantly. For example, the global packaging industry alone demands hundreds of millions of tons of plastic packaging products annually. To meet market demand, plastic product manufacturers are constantly expanding their production scale and improving production efficiency. Screening devices, as an important part of the plastic product processing, can quickly and accurately screen plastic raw materials and products, contributing to large-scale, high-efficiency production.

[0003] In publication number CN216936465U, this utility model discloses a metal screening device for processing plastic products. It includes a support base, a conveyor platform on the top inner wall of the support base, a mounting base on the bottom inner wall of the conveyor platform, a vibration mechanism inside the mounting base, a controller on one outer wall of the support base, a support frame on the top outer wall of the support base, grooves on the four inner walls of the support frame, a collection box on one outer wall of the support base, a cylinder on the bottom inner wall of the support frame, a fixed frame at one end of the cylinder, and the fixed frame slidably connected to the groove, a magnetic separation mechanism on the opposite inner wall of the fixed frame, and a limit plate hinged to the opposite inner wall of the conveyor platform. This utility model, by activating the cylinder, causes the fixed frame to slide within the groove, making the height of the fixed frame adjustable. Simultaneously, the fixed frame drives the magnetic separation mechanism to perform magnetic screening, preventing the presence of metal during plastic processing and thus avoiding interference with the processing effect.

[0004] The aforementioned screening device only supports single-scanning, has low efficiency, and has a relatively fixed structure, making disassembly and replacement troublesome. Therefore, there is an urgent need for a screening device for plastic product processing that can perform multi-scanning and is easy to disassemble and replace. Utility Model Content
