A center surface winding and slitting machine

Abstract

The invention provides a center surface winding and slitting machine, which includes a receiving seat, a transition aluminum wheel, an air expansion shaft, a circular knife lower knife, a circular knife upper knife, a bow roll, a first winding mechanism, and a second winding mechanism , pushing mechanism, unwinding mechanism, dancing wheel, differential manual adjustment wheel, tapered pulley and winding pressure roller, in the present invention, the setting of the first winding mechanism and the second winding mechanism, the first winding The mechanism and the second winding mechanism carry out the surface and center winding separately, and the surface and the center winding are used together, so that the PVDC sticky casing raw film can be wound to the first winding mechanism after slitting. And on the second winding mechanism; the configuration of active winding shaft and active winding pressure roller can accurately perform ultra-low tension when processing ultra-thin, viscous irregular materials such as PVDC casing film, making the film surface smooth and smooth without stretching No wrinkles and other defects; the center surface winding and slitting machine has a simple structure, convenient and fast operation, and is convenient for market promotion and application.

Description

technical field [0001] The invention is a new type of slitting machine with center and surface winding simultaneously, belonging to the technical field of flexible packaging material processing equipment, especially suitable for the processing of ultra-thin, viscous, irregular and ultra-low tension materials such as PVDC casing film. Background technique [0002] PVDC blown film is an excellent packaging material with high barrier properties. It has excellent properties such as low air permeability, oil resistance, chemical resistance, moisture permeability and fragrance retention. Therefore, it is widely used in video packaging, pharmaceutical packaging, precision instruments It is widely used in packaging and electronic product packaging, and has become one of the three best barrier materials recognized in the world; [0003] On the market, according to the material structure and material characteristics of the material to be cut, different winding methods are required.
