Transfer printing film adhesive layer coating device

Abstract

The invention discloses a transfer printing film adhesive layer coating device. The transfer printing film adhesive layer coating device comprises an outer shell, a glue spraying unit, a scraper, a conveying unit, a drying oven, a deodorization unit and a control unit, wherein the conveying unit comprises a feeding roller and a discharging roller which are fixed on the outer side of the outer shell through a supporting frame, and the feeding roller and the discharging roller are wound around the two ends of the base material to be coated and are driven by a first motor and a second motor to rotate respectively; the central section of the base material to be coated extends into the interior of the outer shell and is guided by a plurality of first guide rollers to form a coating plane, a second guide roller is arranged on the lower side of the first guide roller, the rear section of the base material to be coated is guided to form a material scraping inclined surface through the second guide roller, and then passes through the drying oven to finally guide back to the discharging roller; the scraper is fixed at the lower side of the material scraping inclined surface and is in contact with the material scraping inclined surface, a spray head and a glue solution tank of the glue spraying unit are arranged on the upper side of the coating plane and the lower side of the scraper respectively, and the surface sizing speed can be adjusted through the spraying speed of the spray head.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of transfer film, in particular to the technical field of a transfer film adhesive layer coating device. [0003] 【Background technique】 [0004] The aluminum gusset is based on the aluminum alloy plate, which is obtained by cutting, cutting corners and molding. There are two main types, one is the integrated aluminum gusset for home decoration, and the other is the engineering aluminum gusset. With the development, integrated aluminum gussets for home improvement have become various, and various processing techniques have been applied to them. Series such as heat transfer printing, glaze, ink printing, mirror surface and 3D are the most popular integrated aluminum gussets for home improvement in recent years. gusset. Heat transfer printing is a process of transferring the decorative pattern on the heat transfer printing onto the surface of the decorated building material by one-time heating of the ...

Problems solved by technology

However, since the gluing mesh roll is directly immersed in the trough, when the speed of the coating machine is increased, the speed of the corresponding gluing mesh roller also needs to be increased synchronously. Under the action of shearing force, it is very easy to accumulate a large amount in the gap between the doctor blade and the coating roller and splash out uncontrollably, which will cause quality problems such as substrate contamination and uneven gluing

Therefore, the start-up speed of the existing gluing device is limited, which inhibits the production efficiency and reduces the yield of the product

In addition, glue waste gas has a pungent smell. If it cannot be collected and discharged efficiently, it will greatly affect the production and working environment of workers
