Description

Technical Field

[0001] This utility model relates to the field of printing film cutting machine technology, and in particular to a printing film cutting machine for in-mold labeling. Background Technology

[0002] In-mold labeling is a technique used in the blow molding or injection molding process of plastic products. Printed label material is placed directly into a mold, and the label is fused to the product surface under high temperature and pressure. This type of label is made of the same material as the product, possessing waterproof, oil-proof, and mildew-proof properties, and is not easily detached or damaged.

[0003] In the prior art, Chinese patent CN202420092830.0 discloses a heat transfer film slitting machine with convenient blade adjustment, relating to the field of heat transfer technology. It includes a work frame with connecting plates symmetrically fixed to both sides of the top of the work frame. Each connecting plate has a second sliding groove in the middle of its opposite surface. A slitting device is fixedly connected to the middle of the top of the connecting plates. The slitting device includes a connecting table and a through slot. The through slot is located on one side of the top of the connecting table. Cylinders are fixedly connected to both sides of the top of the connecting table, and the output ends of two cylinders are fixedly connected to a limiting plate. Four cutting mechanisms are equidistantly and movably inserted within the limiting plate. Each of the four cutting mechanisms passes through the through slot and is movably and interspersed with a rotating roller. Slider blocks are movably connected to both ends of the rotating roller, and a driver is fixedly connected to one end of one slider. This invention allows for rapid adjustment of the cutting blades according to the printing position on the film, adapting to different printing sizes and offering high practicality.

[0004] Although the aforementioned patent allows for rapid adjustment of the cutting blade based on the position of the printed image on the film, thus adapting to different sizes of prints, when the printing film is at the bottom of the cutting mechanism, the lack of support underneath makes it difficult to adjust the cutting depth due to the elasticity of the printing film, affecting the cutting effect.

[0005] Therefore, this utility model proposes an in-mold label printing film cutting machine to solve the problem in the prior art that the elasticity of the printing film makes it inconvenient to adjust the cutting depth during cutting, thus affecting the cutting effect. Summary of the Invention
