AI Technical Summary
In existing screen changing devices, the gap between the drawing plate and the clamping plate cannot be changed, leading to jamming or glue leakage, which affects the stability and efficiency of the extrusion equipment.
A plate-pulling screen changing device was designed, including a clamping mechanism, a pushing mechanism, and a plate-pulling mechanism. The gap between the plate-pulling device and the clamping plate is adjusted by the guide and the driver to achieve a tight connection and smooth movement of the plate-pulling device, avoiding glue leakage and jamming.
It improves the working stability and continuity of extrusion equipment, reduces maintenance costs, and ensures normal melt flow and filtration effect.
