Description

Technical Field

[0001] The present invention relates to the technical field of film printing devices, in particular to a film printing device for designing pharmaceutical packaging. Background Art

[0002] There are many types of pharmaceutical packaging boxes with varying thicknesses. During the design process, the surface of the packaging box needs to be printed with a film, which is often called lamination. The lamination of pharmaceutical packaging boxes has the advantages of being waterproof, moisture-proof, and damage-resistant. The lamination of pharmaceutical packaging boxes also has the advantage of being convenient for subsequent spraying and printing. At present, in order to improve the quality of lamination (the fit between the printed film and the lamination after lamination), it is usually necessary to perform extrusion and exhaust treatment after laminating the outer surface of the pharmaceutical packaging box. Since the thickness of pharmaceutical packaging boxes varies greatly, in order to improve the fit after printing, it is necessary to use a film printing device with an adjustable thickness function to adapt to the lamination processing of pharmaceutical packaging boxes that need to frequently switch between different thicknesses.

By setting the elastic component into an eight-shaped structure consisting of two struts and a torsion spring, the squeezing force of the outer roller on the film pieces of different thicknesses is increased, which is suitable for processing pharmaceutical packaging boxes with different film thicknesses and greatly improves the flatness of the film after printing;
