Plastic extruder facilitating filtering of impurities

Abstract

The invention provides a plastic extruder facilitating filtering of impurities. The plastic extruder comprises a machine head gland, a fine filter screen, an end plate, a material conveying plate, a filter screen, a vibration motor, a filter cartridge, an injection chamber and a spring, wherein the machine head gland is arranged on the annular left side of a machine barrel, the fine filter screenis arranged on the rear side of the inner part of the machine head gland, and the material conveying plate is arranged on the left end face of the fine filter screen; the filter screen is arranged onthe annular side face of the filter cartridge in a sleeving mode, the filter cartridge is arranged on the left end face of the end plate, the injection chamber is formed inside the filter cartridge, and the spring is arranged on the annular side face of the filter cartridge; and the end plate is arranged on the left side of the material conveying plate, and the filter cartridge is arranged on theleft end face of the end plate. The design solves the problems that an original plastic extruder is poor in filtering effect and prone to being blocked, and the plastic extruder facilitating filteringof the impurities is reasonable in structure, good in filtering effect and convenient to clean and maintain.

Description

technical field [0001] The invention belongs to the technical field of plastic processing equipment, and in particular relates to a plastic extruder which is convenient for filtering impurities. Background technique [0002] After waste thermoplastics are recycled, they need to be reprocessed. Although the thermoplastic is cleaned during this process, there are still impurities in it, which will cause the head of the extruder to be blocked during the extrusion molding process; and the flow rate of the plastic melt is unstable during the extrusion process, causing The plastic quality after extrusion is not high. [0003] In the prior art, the filter effect of the existing plastic extruder head is not good, and the filter is easy to clog, and the clogged inside is not easy to clean, especially the clogging will be difficult to deal with during processing, which will directly affect the production efficiency, and at the same time, improper filtration It will affect the proces...

AI Technical Summary

Problems solved by technology

Although the thermoplastic is cleaned during this process, there are still impurities in it, which will cause the head of the extruder to be blocked during the extrusion molding process; and the flow rate of the plastic melt is unstable during the extrusion process, causing The plastic quality after extrusion is not high

[0003] In the prior art, the filter effect of the existing plastic extruder head is not good, and the filter is easy to clog, and the clogged inside is not easy to clean, especially the clogging will be difficult to deal with during processing, which will directly affect the production efficiency, and at the same time, improper filtration It will affect the processing quality, and now there is an urgent need for a plastic extruder that is easy to filter impurities to solve the above problems
