The mesh belt-type automatic screen changer is a highly efficient melt filtration device used in the production of chemical fibers, pipes, films, sheets, and pellets.

It consists of a slatted contrast mesh belt (the core filtration component), a filter cartridge, inlet and outlet cooling sections, main flow channel connection sections, heating elements, and an electrical control system.

Operation is based on melt pressure and temperature control. When the melt pressure or elapsed time reaches the preset value, the screen-changing cycle is triggered. Heating elements heat the melt, and the filter screen moves under melt pressure, carrying away impurities. After cooling, the melt solidifies to form a seal, preventing leakage. This cyclic operation enables fully automatic screen changing.

The belt-type automatic screen changer is highly efficient and stable, playing a crucial role in the production of high-quality products.
