Coating method

Abstract

The invention relates to a film coating method. The film coating method comprises the steps of coating glue on one end of a film roll in advance or sticking a bonding adhesive tape; separating a firstfilm roller from a second film roller; covering one end of a film on the film roll on an upper roll rod on the first film roller, and enabling a first pressure head to be abutted against the first film roller so as to realize the compression of one end of the film on the film roll on the upper roll rod; and when the film roll on a lower roller rod is close to be stopped from using, enabling the first film roller and the second film roller to be close to one another by a lifting mechanism, and enabling one end of the film on the film roll on the upper roller rod to be bonded with the upper surface of the film on the lower roller rod which is used in advance; starting a cutting knife to perform cutting operation on the joint of the film on the lower roller rod and the film on the film rollof the upper roller rod; and separating the first pressure head from the first film roller, enabling the first film roller and the second film roller to be far away from one another by the lifting mechanism, enabling one end of the film on the film roll on the upper roller rod to be in a free state, starting other devices of a production line, and performing film coating operation on a plate.

Description

technical field [0001] The invention relates to the technical field of film production, in particular to a film coating method. Background technique [0002] In packaging equipment or film equipment, in order to continuously realize the film supply operation, the roll frame is generally used to support the film roll. During the actual use of the film roll, the film roll is wound into a cylindrical structure, and the film roll is placed on the roll frame. On the roller bar, one end of the film roll is pulled out manually, and then the material is supplied to the film, so that the film can be laid on the packaging or on the board; [0003] When the film roll is used up, the entire system needs to be shut down, and then a new film roll is replaced on the roll stand, and then the new film is pulled out from the film roll again, and the film is passed through various transfer rollers, so that Realize the feeding operation of new film. However, when replacing the film roll, the p...

Problems solved by technology

[0003] When the film roll is used up, the entire system needs to be shut down, and then a new film roll is replaced on the roll frame, and then the new film is pulled out from the film roll again, and the film is passed through various transfer rollers, so that Realize the feeding operation of new film. However, when replacing the film roll, the production efficiency of the system will drop due to the need to stop. When operating on the sheet film, the previously used film cannot be integrated due to the film roll replacement process. Covering a plate will cause the film and film flowers to fail to align, which will directly lead to the scrapping of the plate and part of the film on the production line, directly causing significant economic losses
