Description
Technical Field
[0001] The utility model belongs to the technical field of film production, and in particular relates to an equidistant cutting device used in film production. Background Art
[0002] Film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of film is: a 2D material formed by atoms, molecules or ions deposited on the surface of a substrate. Examples: optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. Film is widely used in electronics, machinery, printing and other industries. Film material refers to a thin metal or organic layer with a thickness ranging from a single atom to several millimeters. Electronic semiconductor functional devices and optical coatings are the main applications of thin film technology.
[0003] In the process of film production and processing, sometimes cutting is required. The purpose of cutting is to cut materials with large specifications and widths into materials of small specifications. Therefore, equidistant batch cutting comes into being, which can cut multiple materials of the same specifications at one time. However, during the equidistant cutting process, the cutting device is not equipped with a limit anti-bias holding mechanism for the material before cutting and a cleaning mechanism for the debris on the surface of the material after cutting. Since there is no limit anti-bias mechanism when the material is transported before cutting, it is easy to deviate, which affects the accuracy of the cutting operation. The residual debris after cutting will bring inconvenience to the subsequent production and use. Utility Model Content

Since there is no limiting and anti-bias mechanism when the material is transmitted before cutting, it is easy to deviate, which further affects the cutting operation accuracy. The residual debris after cutting will bring inconvenience to the subsequent production and use.
