Abstract

The invention relates to a film cold-pressing device. The film cold-pressing device comprises a rack, a press roll and a bracket, wherein the press roll is rotationally connected to the rack, the bracket is arranged on the rack, a material accommodating groove is formed in the rack and is formed in a feeding end of the press roll, glue is accommodated in the material accommodating groove, a gluing shaft is rotationally connected above the material accommodating groove and is in drive connection with the press roll, a material supply assembly is connected to the material accommodating groove, a material unrolling shaft is arranged on the bracket, and a material rolling shaft for rolling a film is arranged on the bracket. The film cold-pressing device has the advantages as follows: the glue is uniformly applied to paper by the aid of the gluing shaft, the film is unrolled on the paper by means of the material unrolling shaft, the film and the glue are bonded via the press roll, the defect of difficulty in temperature control with an existing hot film pressing process is overcome, the scrappage of paper and films is reduced, and the qualification rate and the yield of products are increased; the material unrolling shaft is arranged right above the gluing shaft, synchronous operation of film feeding and paper gluing can be guaranteed, and the film bonding accuracy is improved.

Description

Technical field [0001] The invention relates to a cold pressing film device. Background technique [0002] Existing packaging bags need to be molded with a layer of plastic film during the production process. The existing plastic film layers are all coated by a hot press molding process during production. In the current production process, due to the level of the operator Differences result in the inability to stably control the temperature during the operation of the hot-pressing film process, causing damage to the plastic film, increasing the scrap rate of the product, and increasing the production cost. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a cold pressing film device, which solves the problem of high rejection rate of the existing plastic film pressing mold. [0004] In order to solve the above technical problems, the present invention is realized through the following technical solutions: a cold pressing fil...
