Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch drying and crushing, and more specifically, to a polyethylene plastic masterbatch drying and crushing device. Background Art

[0002] Polyethylene plastic masterbatch, also known as PE masterbatch, is an important plastic raw material, mainly composed of the polymer material polyethylene (PE). Polyethylene plastic masterbatch is one of the basic raw materials for plastic products, with its main component being polyethylene, which is a non-toxic and environmentally friendly material with stable properties and is widely used in various fields. In the automotive manufacturing industry, polyethylene masterbatch can be made into automotive exterior parts, interior parts, and functional parts, etc., to meet the usage requirements of automotive components;

[0003] The dried polyethylene plastic masterbatch has better fluidity and is suitable for processes such as high-pressure injection molding. The masterbatch with good fluidity can fill the mold more evenly during molding, reducing the generation of defects. The crushing process can break large plastic masterbatches into smaller particles, facilitating subsequent mixing, conveying, and molding.

[0004] Among them, through retrieval, it is found that the patent with the patent application number CN202022850701.8 discloses a material crushing device for polyethylene resin production, which relates to the field of material crushing for polyethylene resin production, including a tank body. The right side of the top of the tank body is fixedly connected with a feeding hopper, the top of the tank body is fixedly connected with a first motor, the output shaft of the first motor is fixedly connected with a rotating rod through a coupling, the rotating rod penetrates through the top of the tank body and extends downward into the tank body, and the rod wall of the rotating rod is rotationally connected with the upper side wall of the tank body through a first bearing. Both the left and right side walls of the rotating rod are fixedly connected with a plurality of first crushing knives. The left and right sides of the inner wall of the tank body are jointly fixedly connected with a partition plate. An inclined filter screen is arranged inside the tank body, and the right end of the filter screen penetrates through the right side of the tank body and is fixedly connected with a spring;

[0005] When this structure is in use, it can crush the material twice, crush the material thoroughly, and can dry the material to avoid a small amount of material from caking. At the same time, it balances the vibration generated by the tank body and the crushing box. However, when this structure is in use, it is not easy to gather the raw materials, resulting in the raw materials being prone to spreading during crushing, resulting in low crushing efficiency. At the same time, it is not easy to synchronize crushing and heating, resulting in poor crushing effect. Summary of the Utility Model
