Double-column No-Wobble Screen Changer: It can be said that the screen changer has been reinvented. This invention makes the original single-column screen changers obsolete. The core value of this screen changer is that, with the same cylindrical structure, the filtration area is over 4 times larger, and its functionality is completely different, ensuring high-pressure no-leakage. The screen change is more convenient, with no fluctuations and no blind spots. During the screen change, pressure control automatically extends and retracts, automatically fills material, and can automatically exhaust air. This ensures that the extruder can continue uninterrupted without affecting the quality of the extruded product. It can be used on any extrusion equipment, such as blow film machines, drawing machines, packaging tape machines, pipe extrusion machines, granulators, and fiber spinning equipment, without the need to stop the machine, thereby avoiding waste.
