AI Technical Summary
In the existing technology, the texture of the PVB film and the extrusion roller are designed as an integral part, which makes the disassembly process cumbersome when changing the texture and affects the efficiency of operation.
The design incorporates a combination of a mold body, a casting extrusion die head, extrusion rolls, extrusion sheets, a positioning and locking mechanism, and a clamping and locking mechanism to enable convenient disassembly and replacement of the extrusion sheets.
It simplifies the pattern replacement process, saves time, and improves the operating efficiency of PVB membranes.
