Abstract

The invention discloses an adhesion device for a transparent packaging film. An adhesion interface of the packaging film is smooth, the adhesion intensity is reliable and transparency is good. The adhesion device comprises a rack and a conveyor belt arranged on the rack. Barrier strips are arranged on the two sides of the conveyor belt and used for protecting packaging film folding lapping openings in the two ends of a packaging case and guiding and positioning the packaging case. The two sides of the conveyor belt are each vertically provided with first rotary iron, and the first rotary iron is used for adhesion of the packaging film folding lapping openings in the two ends of packaging case. Second rotary iron is horizontally arranged above the conveyor belt and used for adhesion of a long edge lapping opening of the packaging film of the packaging case. The first rotary iron and the second rotary iron are both driven by a motor. Local air left between two layers of films to be bonded as well as between multiple layers of films at the folding position when existing planar iron and a transparent film adhere integrally can be effectively eliminated, and the problem that adhesion of the film lapping opening is not firm and transparency is not high when air cannot be exhausted is solved.

Description

technical field

[0001] The invention relates to the technical field of transparent film bonding equipment for packaging boxes, in particular to a bonding device for transparent packaging films. Background technique

[0002] The existing mechanical equipment for wrapping the transparent film out of the product packaging box is all bonded by heating, so that when the product packaging box is repeatedly opened and closed by a heated soldering iron, it acts on the joint of the transparent film to be bonded for a certain period of time. The thermal bonding of the lap of the transparent film can be completed; when the area of ​​the lap of the transparent film to be bonded is large or the number of laps at both ends is large, it is often because there is a small amount of air or moisture between the transparent films and the built-in packaging box The surface is uneven, the surface of the soldering iron is not fully bonded to the surface to be packaged, or the electrostatic adsorpt...
