Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a fixed cutting device of a laminating machine. Background Art

[0002] Lamination is a major process in post-printing processing, which involves bonding a plastic film coated with adhesive to a paper printed matter after heating and pressurizing. The laminated printed matter has a smoother and brighter surface due to an extra layer of thin and transparent plastic film, which not only improves the gloss and fastness of the printed matter and extends its service life, but the plastic film also provides protection against moisture, water, dirt, wear, folding, and chemical corrosion.

[0003] For example, the fixed cutting device of an automatic pre-coating film laminating machine with the authorization announcement number "CN219987857U" pierces the film through a number of cutting blades, making it easy to tear the film off, thereby improving the efficiency of cutting the film. At the same time, the fixed frame is used to lift the film upward, which is convenient for the staff to find the film and pull it, thereby improving the efficiency of product laminating and facilitating the use of the user. The fixed cutting device of the automatic pre-coating film laminating machine passes the film through the bracket and covers it on the movable plate, and then uses the electric telescopic rod to pull the film, but the movable plate cannot clamp and fix the film, resulting in the electric telescopic rod being unable to pull the film and the film being unable to move. At the same time, after each cutting of the film, manual collection operations are required, which reduces the working efficiency of the fixed cutting device of the automatic pre-coating film laminating machine.
