Degumming device for plastic film for packaging printing

The invention discloses a degumming device for a plastic film for packaging and printing. The degumming device comprises a base body and a degumming mechanism arranged on the base body. A support column is arranged on one side of the base body. A lever arm driven by a motor is hinged to the support column. The degumming mechanism comprises a cross box body connected to the lever arm. One side of the bottom of the cross box body is slidably connected with a vertical box body. Both the cross box body and the vertical box body are of a hollow structure. An inner cavity of the cross box body communicates with an inner cavity of the vertical box body. The cross box body communicates with a liquid inlet pipe of a degumming agent. Opposite plastic plates are correspondingly arranged on the front side and the rear side of the base body. A closed space for containing the plastic film is jointly defined by the plastic plates on the front side and the rear side, the cross box body and the vertical box body, and multiple spray holes are formed in the ends, facing the closed space, of the cross box body and the vertical box body. An ejection unit for pushing the vertical box body to horizontally move along the bottom of the cross box body is mounted on the support column. The degumming device aims at solving the problems that by means of an existing degumming manner, the waste of the degumming agent is caused, the environment is polluted, and the plastic base material is damaged.
