Plastic pellet machine screen changer is suitable for sheet, plate, pipe, laminating, blown film, wire, cable, profiles, pelletizing, etc. Suitable for all thermoplastics.
thermoplastic extruder screen changer
The working principle of thermoplastic extruder screen changer is mainly divided into three steps: conveying of molten plastic, replacement of filter screen and material switching.
1. Molten plastic conveying: Thermoplastic Extruder Screen Changer melts the plastic granules into melt and conveys them into the filter screen by the action of heating and pressure.
2. Filter screen replacement: When it is necessary to replace the filter screen, the hydraulic system will drive the screen changer to perform a fast and accurate action to pull out the old filter screen from the head while inserting the new one into the head.
3. Material switching: while replacing the filter mesh, the screen changer can also realize material switching, i.e., different materials will be transported to the machine head through different pipelines and runners to meet the needs of different production processes.

Plastic granule machine screen changer features
1、The plastic granule machine screen changer adopts the whole structure, which is characterized by small volume and short flow channel, and can be used with different standard extruders.
2、Adopting pressure-driven sealing technology, the sealing gap can be automatically compensated to meet the high extrusion output production of any polymer material without stopping and leaking.
3、Hydraulic pump station is equipped with a pressure storage device, double-station rapid screen change time ≤ 2 seconds.
4、It will not affect its performance under pressure 25-30Mpa and temperature up to 300℃.
5、Filtering area ¢50-¢360mm optional.
