Description

Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene membranes, in particular to low-energy-consumption and uniform composite equipment for polytetrafluoroethylene membranes. Background Art

[0002] Due to its excellent chemical stability, high-temperature resistance, and lubricity, polytetrafluoroethylene (PTFE) membranes are widely used in food packaging, electronics, aerospace, and other fields. However, traditional polytetrafluoroethylene membrane lamination processes suffer from high energy consumption, uneven lamination, and low production efficiency. In particular, significant energy loss during the heating process compromises both the economic and environmental performance of production.

[0003] CN217834781U discloses a PTFE membrane laminating device that combines heat lamination and adhesive lamination into one device, shortening the production cycle, improving production efficiency, and saving labor. CN212549053U discloses a laminating device for high-permeability air purification composite membranes. The laminating process uses a single roller heating and a pressure roller pressurization method to enhance the lamination strength between the nanofiber membrane and the non-woven fabric substrate. CN216122968U discloses an electrostatic eliminator for the PTFE membrane production process. By adding an electrostatic eliminator roller, the surface static of the composite membrane is released, improving production safety. Summary of the Invention

[0011] Furthermore, the transmission speed of the transmission device is the same as that of the winding device.

[0012] Furthermore, the winding device is 1-2 meters away from the hot pressing roller.

[0013] Beneficial Effects: The utility model discloses a low-energy, uniform composite device for polytetrafluoroethylene membranes. The unwinding device is connected to a base for placing the polytetrafluoroethylene membrane and supporting material to be composited. The preheating device preheats the polytetrafluoroethylene membrane and supporting material to improve the mutual adhesion during composite.
