Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to an anti-blocking device for an extruder used in the production of ABS plastic particles. Background Art

[0002] The production of plastic pellets is to melt the raw materials, extrude them from the extruder to form long strips, and then use an external pellet cutter to collect the strips and cut them into pellets.

[0003] The outlet of the extruder has a small aperture, and the hot-melt plastic material easily adheres to the inner wall and port of the outlet. The general method to clean the outlet is to heat the extruder block to melt the material blocking the outlet and make it flowable. The operator will use an air gun to blow the material out of the outlet. This method can roughly clear the material blocking the outlet, but because it cannot completely clean the inner wall of the outlet, the inner wall will still have residue, and the outlet hole may be blocked again at any time.
