Description

Technical Field

[0001] The utility model relates to the technical field of protective film production, in particular to a protective film longitudinal stretching casting device. Background Art

[0002] The protective film longitudinal stretching casting device is a device used to produce protective film. It forms the required protective film by melting, extruding, stretching, cooling and other processes of the raw materials. Its working principle is that first, the raw materials are passed through the heating zone of the extruder to melt the raw materials, and then the molten raw materials are extruded through the extrusion head of the extruder to form the shape of the protective film. Then, the extruded protective film is longitudinally stretched by the stretching device to give the protective film the required strength and toughness. Finally, the stretched protective film is cooled by the cooling device to solidify it. Finally, the protective film is cut into the required length and width by the cutting device.

[0003] Common protective film longitudinal stretching casting devices are usually not equipped with dust collection devices when in use. The dust generated inside the workshop during production may not be removed in time. Dust and debris may adhere to the surface of the protective film, affecting the transparency, strength and toughness of the protective film, thereby reducing product quality and bringing certain adverse effects to people's use process. For this reason, we propose a protective film longitudinal stretching casting device. Utility Model Content
