Description

Technical Field

[0001] The utility model relates to the technical field of packaging film printing, and particularly relates to a packaging film printing device. Background Art

[0002] A packaging film refers to a thin film used for packaging items, usually including polyethylene film, biaxially oriented polyester, BOPP film, CPP film, etc., and is mainly used for packaging food, medicine, and textiles. In order to improve the aesthetics of the packaging film, an ink printing device is used to print patterns on the outer surface of the packaging film.

[0003] The existing Chinese patent with the authorized announcement number of CN219988750U discloses a packaging film ink printing device, including a base. Two brackets are fixedly installed on the base. A top plate is fixedly installed on the two brackets together. An ink tank and a suspension bridge are fixedly installed on the top plate. A cover body is fixedly installed on the suspension bridge. An oil absorption cotton is installed in the cover body. The oil absorption cotton penetrates through the cover body and extends into the ink tank. A printing roller is rotatably installed on the cover body. Two telescopic rods are fixedly installed on the base. A backing plate is fixedly installed on the two telescopic rods together. The ink is applied to the printing roller through the oil absorption cotton, which can greatly reduce the concentration of the ink on the printing roller, make the ink on the printed packaging film dry faster, effectively improve the winding efficiency of the packaging film, and at the same time, the pressing force between the pressure roller and the printing roller can be adjusted, which can effectively reduce the probability of unclear printing caused by the loosening of the pressure roller, and has higher practicability.

[0004] The deficiencies of the above existing technical solutions are as follows: During the transportation of the packaging film, the inclination of the packaging film will be caused due to the asynchronous rotation speed of the conveying rollers, resulting in the skewing of the printed pattern. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a packaging film printing device to solve the technical problem that during the transportation of the packaging film in the prior art, the inclination of the packaging film will be caused due to the asynchronous rotation speed of the conveying rollers, resulting in the skewing of the printed pattern.
