Problems solved by technology

[0007] In order to solve the above problems, the object of the present invention is to provide a centered air-permeable composite film centered unwinding device and its processing method, which solves the problem of low production efficiency of the centered composite film production equipment, as much as possible on a smaller footprint. The centered composite film production can be carried out efficiently, and at the same time, it can overcome the poor control of the unwinding tension caused by the uneven surface tension caused by the change of the roll diameter during the winding process of the plastic film and its own shrinkage performance during the synchronous production of multiple centered composite films.

Abstract

The invention discloses a centered breathable composite film centered unwinding device and a processing method thereof. The device comprises a rack, a control panel, an actuator and more than one unwinding inflatable short shaft are mounted on the rack, and the control panel is connected with the actuator which is connected with the unwinding inflatable short shafts. The centered breathable composite film centered unwinding device and the processing method thereof solve the problem of low production efficiency of centered composite film production equipment, centered composite film production can be realized to the greatest extent on a small occupied area, and the defect of poor unwinding tension control caused by nonuniform surface tension due to winding diameter changes and contractility of a plastic thin film during winding of the plastic thin film when multiple centered composite films are produced synchronously is overcome.

Description

technical field [0001] The invention relates to a central unwinding device and a processing method for a central air-permeable composite film. Background technique [0002] Breathable film is a kind of microporous film, which has the characteristics of moisture permeability but not water permeability; non-woven fabric, also called non-woven fabric, non-woven fabric, has good air permeability and superior physical strength. The air-permeable film and the non-woven fabric are combined into one by means of gluing, hot pressing, etc., which is called a breathable composite film. Because the breathable composite film combines the unique properties of the breathability of the breathable film and the mechanical strength of the non-woven fabric, it can be widely used, among which diapers are one of the most common application fields. [0003] At present, breathable composite membranes are classified according to their appearance, mainly including full-width and centered. Full-widt...
