Description

Extruding machine

Technical Field

The utility model relates to a rubber production facility technical field particularly, relates to an extruder.

Background

The screw extruder depends on the pressure and the shearing force generated by the rotation of the screw, so that materials can be fully plasticized and uniformly mixed and are molded through a neck mold. Its main structure includes: the device comprises six parts, namely a transmission part, a feeding device, a charging barrel, a screw, a machine head, a die and the like.

A filter screen is arranged at an inlet of the neck mold in the extruder and used for filtering impurities in the rubber and improving the quality of a molded product. The filter screen needs to be changed regularly, need dismantle the bush when changing each time, takes out the filter screen that will use again, adorns new filter screen, later fixes the bush again with the feed cylinder. Because the bush is fixed with the charging barrel through a plurality of screws, a large number of screws need to be unscrewed during disassembly, and the disassembled screws need to be unscrewed again during installation, so that the operation is troublesome and the process is complicated when the filter screen is replaced every time.

In view of this, the present inventors have invented an extruder.

Disclosure of Invention
