Automatic screen changer for plastic machinery
Automatic belt screen changer for plastic extrusion machine
The automatic belt screen changer is a compact, self-contained screen changer that eliminates the need for hydraulics, screen packs, breaker plate cleaning or replacement, with no electric motors or hydraulics.
Features of Automatic screen changer for plastic machinery
•Continuous production with automatic and constant screen changing process, no manual operation.
•Minimized material flow and pressure fluctuation during whole production process, excellent product stability.
•Reducing waste and raw materials consumption.
Benefits of Automatic screen changer for plastic machinery
•It guarantees continuous production, and requires no operator assistance while running.
•Higher Product Quality
•It has no motor or moving mechanical parts. It requires minimum maintenance interventions, continuous production achievable evening during belt screen replacement.
How to work
The screen moves across the flow of plastic melt and a fresh screen enters as the spent filter screen exits; removing the impurities from the raw material. The belt screen changer is fitted between the end flange of the
extruder and the die. A cassette holding a roll of screen filter is attached to the side of the belt screen changer block. The controlling box of belt screen changer is equipped with a pressure sensor, and a pressure warning device, when the pressure is raise to the preset , it will automatically alarm, at the same time, the screen is replaced automatically. And the cooling system begin to work , the impurity is cooled and moved out with the filter screen.
