Description

Technical Field

[0001] The utility model relates to the technical field of composite film processing, in particular to a device for dividing composite films for drug packaging. Background Art

[0002] Pharmaceutical packaging composite film, also known as composite film for pharmaceutical packaging, is a flexible packaging material specially used for pharmaceutical packaging. It is usually composed of two or more materials of different properties through physical or chemical methods to achieve specific packaging performance requirements. In the process of producing pharmaceutical packaging composite film, segmentation is a necessary step. The purpose of segmentation is to segment the composite film according to specific sizes and shapes for subsequent packaging and use.

[0003] Pharmaceutical packaging composite films are usually shipped in the form of rolls. When cutting, the composite film needs to be unrolled from the reel and then cut. However, when unrolling the composite film, the composite film is prone to bend. It is difficult to control the length of the composite film in the bent state when cutting, which affects the accuracy of the cutting and causes the shape of the composite film sheets after cutting to be uneven, affecting the subsequent packaging work. Therefore, a cutting device for pharmaceutical packaging composite films is proposed. Utility Model Content
