Description

Technical Field

[0001] The present application relates to the technical field of pre-coating film production, and in particular to a glue coating device. Background Art

[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film and then compounding it with paper printed products. The pre-coating factory first applies glue on the film according to the specifications and format, and then rewinds it for the user to choose, and then compound it with the printed product. Lamination, that is, film pasting, is to coat the plastic film with adhesive, and heat and pressurize it to bond it together with the paper printed product to form a processing technology of paper-plastic integrated products. At present, most pre-coating film gluing devices have poor gluing uniformity, which affects the use of pre-coating film. At the same time, when gluing, if the glue is left for a long time, it will solidify. If it is glued again, it will be re-processed, which is quite a waste of time.

[0003] In order to solve the above problem, a gluing device is disclosed in the patent document with the announcement number CN218962994U, which includes two support seats and a storage cavity. A feeding cavity is fixedly provided on the upper ends of the two support seats. A pressing plate is provided on the inner side wall of the feeding cavity. A plurality of cylinders are fixedly provided on the upper end of the feeding cavity. The lower ends of the plurality of cylinders are fixedly connected to the pressing plate. A feeding pipe is fixedly connected to the bottom of the storage cavity. A universal tube is fixedly connected to the lower end of the feeding pipe and extends into the feeding cavity. A first nozzle is fixedly connected to the lower end of the universal tube and passes through the pressing plate. A shell is fixedly provided on one side wall of the storage cavity near the upper end. A second motor is fixedly provided on one side of the shell. In the utility model, the gluing device has the function of evenly applying glue, and at the same time, the gluing device has the function of preventing glue from solidifying.

[0004] In actual use, it was found that the above-mentioned related schemes still have at least the following shortcomings: the glue liquid sprayed from multiple second nozzles is sprayed on the surface of the pre-coated film. Since there is a certain distance between the multiple second nozzles, it is easy to cause the glue liquid sprayed on the surface of the pre-coated film to be not uniform and flat, and there is a deviation in the thickness of the applied glue liquid, resulting in poor gluing effect, and when the amount of glue applied is too large, the dripping glue liquid cannot be recovered and reused, resulting in a waste of glue liquid. Therefore, we propose a gluing device for solving the above problems. Utility Model Content
