Description

Automatic laminating device of panel Technical Field The invention relates to the technical field of laminating equipment, in particular to an automatic laminating device for plates. Background The plate coating is a common surface decoration process, and the glossiness, the wear resistance, the weather resistance and the waterproof performance of the plate can be obviously improved by coating a layer of plastic film on the surface of the plate, the conventional coating technology generally conveys the plate through a conveyor belt, and the conventional coating technology is mainly divided into a film coating mode and a precoating film coating mode according to different coating processes. However, the existing plate laminating technology has a common problem in long-term use that the laminating layer is easy to fall off from the surface of the plate, and the falling off starting point is almost completely concentrated in the edge area of the plate. Specifically, the edge of the plate is subjected to the largest stress concentration by the film coating layer at the edge in the subsequent processing or using process, and the edge of the plate is subjected to moisture absorption and expansion when the ambient humidity changes. These factors work together to cause the coating to progressively peel away from the edges of the sheet and spread toward the central area, ultimately resulting in product failure. Aiming at the edge stripping problem, the prior art mainly adopts the following improvement measures. And a thicker adhesive layer is uniformly coated on the whole surface of the plate so as to indirectly improve the edge adhesion by enhancing the overall adhesive strength. Although the scheme improves edge bonding to a certain extent, severe waste of the adhesive in the central area is caused, and the appearance defects such as orange peel and the like can be caused on the surface of the film due to the excessively thick adhesive layer. And an edge press roller is arranged in the laminating equipment, so that the edges of the plates are additionally pressed. However, due to the height difference between the edges and the central area of the plate, such as chamfer and circular arc edge, the mechanical compaction is difficult to realize uniform pressure application, and the film is easy to damage. Or after the film coating is finished, carrying out secondary gluing or hot-melting edge sealing treatment on the edges of the plates. According to the scheme, additional working procedures and equipment are added, the production efficiency is reduced, an interface exists between the secondarily treated adhesive layer and the original film-covered layer, and the risk of secondary stripping still exists in long-term use. Disclosure of Invention In order to overcome the defects, the invention provides an automatic plate laminating device which can realize the adhesive reinforcement of a plate edge laminating film and prevent the laminating film from falling off.
