Continuous screen changer-automatic mesh belt screen changer

The automatic mesh belt screen changer is mainly composed of the screen changer, the heating and cooling system, and the electric control system. There is no need of manual operation of the screen changer because the material fluid inside flows by itself under the pressure caused by the melt production.

•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.

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.

•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.
