Center and surface winding slitter machine

Abstract

The invention provides a center and surface winding slitter machine. The center and surface winding slitter machine comprises a material receiving base, transition aluminum wheels, an air shaft, a lower circular knife slitter, an upper circular knife slitter, an arch-shaped roller, a first winding mechanism, a second winding mechanism, a material pushing mechanism, an unwinding mechanism, a dancing wheel, a differential hand adjusting wheel, a conical pulley and winding compression rollers. According to the center and surface winding slitter machine, through the arrangement of the first winding mechanism and the second winding mechanism, the first winding mechanism and the second winding mechanism are in a winding mode of separately winding the surface and the center, and a winding mode ofwinding the surface and the center simultaneously is adopted, so that a PVDC viscous casing raw film can be separately wound on the first winding mechanism and the second winding mechanism after being slit; and through the configuration of an active winding shaft and active winding compression rollers, ultra-low tension can be accurately executed when ultra-thin and viscous irregular materials such as the PVDC casing film are processed, so that the film surface is flat, smooth, free of stretching, free of wrinkling and the like. The center and surface winding slitter machine is simple in structure, convenient and fast to operate and convenient to popularize and apply in the market.

Description

technical field [0001] The invention is a novel slitting machine with simultaneous winding of the center and the surface, which belongs to the technical field of flexible packaging material processing equipment, and is especially suitable for processing ultra-thin, viscous, irregular, and ultra-low tension materials such as PVDC casing film. Background technique [0002] At present, there are only a few countries in the world that have processing capacity. They are high-tech products in the plastic processing industry. Foreign countries have imposed a technological blockade on my country for a long time. They do not provide technical software and equipment, but only provide high-priced films to my country. Products, PVDC blown film is an excellent packaging material with high barrier properties. It has low air permeability, oil resistance, chemical corrosion resistance, moisture impermeability, and fragrance retention. It is widely used in the packaging of precision instrument...
