Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of product filtering, in particular to an automatic filtering device for finished products of a twin-screw base material line. Background Art
[0002] The twin-screw fully automatic production base material line is a highly efficient plastic processing equipment, which is mainly composed of a twin-screw extruder, a metering system, a feeding system, an electronic control system, a heating system, a temperature control system, a cooling system and a vacuum system. The finished products produced by the twin-screw fully automatic production base material line are transported into the base material storage tank through a pipeline.
[0003] An existing twin-screw base material line finished product automatic filtering device, during production, some packaging waste in the product raw materials will enter the production system from time to time when feeding, which will have a certain impact on the appearance of the product. Originally, a single-hole filter plate was used for filtration. As the production time increased, more impurities appeared in front of the filter plate, causing the twin-screw head pressure to be too high, and the filter plate had to be stopped for cleaning. Now a double-hole filter plate is used for filtration, which can automatically interchange the filtration through the upper and lower plate limit recognition and pressure, eliminating the need to stop the machine to change the filter screen during startup.

[0011] Through the above technical solution, the number of the limiting grooves is set to four, which is convenient for limiting the internal double filtering slide plate when the position height is raised or lowered.
