Description

Technical Field

[0001] This utility model relates to the field of production and processing technology, specifically to a plastic batching and granulation equipment. Background Technology

[0002] In daily life and factory production, there is often a lot of waste, among which waste plastic is the most common. If it is discarded directly, it will cause environmental pollution. With the increasing awareness of environmental protection, waste plastic has been well recycled. Currently, the recycled waste plastic is heated and melted, and the molten waste plastic is extruded through a plastic extruder and then pulverized into granules.

[0003] A search revealed application number CN201920304079.5, titled "Plastic Granulation Equipment." This application addresses the issue that some granulators can only process granules of one size. For different product specifications, production requires changing equipment, increasing costs and reducing efficiency. The application addresses this by setting the die plate to be non-fixed and replaceable, allowing for different die plate replacements to meet varying production needs and produce different types of plastic granules. Controlling the blade speed allows for the production of granules of different lengths. The heating layer and heating blocks meet the temperature requirements within the material barrel. Using a multi-hole die plate significantly improves efficiency. However, this application requires a plate resetting and refilling after the material in the barrel is depleted, interrupting granulation and resulting in long waiting times, reduced work continuity and efficiency. Further improvements are needed. Additionally, the application still requires manual die plate replacement, which is not quick or convenient and requires further refinement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
