Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a plastic extruder filtering device. Background Art

[0002] Plastic extruder filter is a device used to filter plastic melt. Its main purpose is to prevent impurities from entering the extruder and ensure the quality and performance of plastic products. The filter usually includes one or more filter screens, support structures and filter media.

[0003] During the plastic extrusion process, raw materials, plasticizers and additives may be mixed, degraded, crystallized and other changes may occur. These changes may cause the extruded plastic to not meet the design requirements. Therefore, it is necessary to use a plastic extruder filter device to filter the plastic during extrusion. However, the design structure of the traditional plastic extruder filter device is relatively simple, which makes it inconvenient to disassemble and replace the filter plate. This leads to the maintenance and cleaning process becoming difficult if the filter plate cannot be disassembled. This may lead to reduced efficiency of equipment use, because the machine may continue to operate with the filter plate clogged, and in the long run, this may increase the overall maintenance cost, because replacing damaged filter plates may be cheaper than repairing them, especially when the design of the filter plates makes them difficult to repair.
