Aluminum plastic film production equipment

Abstract

The invention discloses aluminum plastic film production equipment. The aluminum plastic film production equipment comprises an unwinding device, a preheating device, a composite extrusion device, a bonding device and a winding device, the unwinding device is used for unwinding aluminum foil, and the preheating device is arranged on one side of the unwinding device; the composite extrusion device is arranged on the side, away from the unwinding device, of the preheating device and comprises an extruder and a composite mechanism, the extruder is used for extruding a composite film, and the composite mechanism is used for compounding the composite film on the surface of the aluminum foil; the bonding device is arranged on the side, away from the preheating device, of the composite extrusion device and used for bonding the composite film to the surface of the aluminum foil, the winding device is arranged on the side, away from the composite extrusion device, of the bonding device and used for winding the aluminum plastic film, the unwinding device, the preheating device, the composite extrusion device, the bonding device and the winding device drive the aluminum foil to move in the conveying direction through driving rollers. According to the technical scheme, the adhesiveness of the aluminum-plastic film is improved, and the product quality of the aluminum-plastic film is improved.

Description

technical field [0001] The invention relates to the technical field of film coating processing equipment, in particular to an aluminum-plastic film production equipment. Background technique [0002] Aluminum-plastic composite film is the packaging film for pouch batteries, power batteries, etc. While the demand for batteries is increasing, the demand and performance requirements for aluminum-plastic films used for battery packaging are also getting higher and higher. During the production process of aluminum-plastic film, the film is extruded and pasted on the surface of aluminum foil to protect the aluminum foil. In the related technology, after the composite film is attached to the surface of the aluminum foil, the aluminum-plastic composite film is rolled up. The viscosity of the aluminum-plastic composite film produced in this way is not high, which is easy to cause the separation of the film and the aluminum foil, affecting the aluminum-plastic composite film. And th...
