Problems solved by technology

Chinese invention patent CN101551874A provides a lamination process that has been using electronic label lamination equipment. This process includes collecting and discharging, die-cutting, testing, and waste discharge. However, the lamination process is relatively simple and does not require precise alignment. position, unable to meet the requirements for multiple lamination of flexible films with multi-layer structure

Abstract

The invention discloses a method for continuous laminating of flexible thin films with a multilayer structure, comprising the steps of: (1) carrying out die cutting and waste stripping treatment on a first flexible thin film and a second flexible thin film to make a protective layer on one side of each thin film be stripped and to cut rectangular incisions arranged in an array on a useful layer in the middle of each thin film; (2) taking a third flexible thin film as an intermediate layer for laminating, stripping a protective layer on one side first, then laminating the surface stripped with the first flexible thin film in the preparation stage to obtain a flexible film with a four-layer structure; and (3) stripping a protective layer on the other side of the third flexible thin film and laminating the surface stripped with the second flexible thin film in the preparation stage to obtain a composite film with a five-layer structure. The invention further discloses a device for continuous laminating of flexible thin films with a multilayer structure. With the laminating device and the technological method thereof provided by the invention, half-cut die cutting and accurate counterpoint laminating of flexible thin films with a multilayer structure can be realized effectively.

Description

technical field [0001] The invention relates to the field of film lamination, in particular to a lamination method of a flexible film with a multilayer structure, and equipment for implementing the method for precise feeding and alignment lamination. Background technique [0002] Multi-layer structure film lamination process is widely used in printing, packaging and other industries, mainly involving film conveying, die-cutting, waste discharge, slitting and rewinding, etc. Since the functions of each process are relatively independent, there are many single-function module equipment, such as China Utility model patent ZL 200820092979.X provides a precision die-cutting device, Chinese utility model patent ZL95216846.4 provides a waste discharge machine, Chinese utility model patent CN201849992U provides a waste discharge mechanism, and Chinese utility model patent CN201020184129 provides A slitting machine is developed. In practice, various functional modules can be combined...
