Description

Technical Field

[0001] The utility model relates to the technical field of film coating equipment, in particular to a color box ultra-vacuum film coating uniform pressure device. Background Art

[0002] In the process of color box processing, it is usually necessary to coat the raw paperboard for producing color boxes to make the paperboard dustproof and waterproof, thereby protecting the paperboard as a whole and making it more practical. For this purpose, a coating process is required to achieve the above functions. The coating process is generally completed on a vacuum coating machine. The principle process of coating is as follows: the formed pulp embryo is placed in a space called a vacuum chamber with an opening on the top, and then the opening of the vacuum chamber is covered with a softened thermoplastic film, and then the vacuum chamber covered with the film is vacuumed. At this time, the film naturally adheres to and adheres to the upward surface of the pulp embryo, and finally the pulp embryo covered with the film is taken out of the vacuum chamber.
