Description

Technical Field

[0001] The invention relates to the technical field of decorative plate processing, and in particular to an automatic side closing device of a decorative plate. Background Art

[0002] Building panels are usually used on the exterior walls of buildings. On the one hand, they can increase the decorative effect of the exterior walls of buildings, and on the other hand, they can increase the thermal insulation performance of the exterior walls of buildings. Panels are usually rectangular in structure. The front of the panels is usually provided with decorative patterns. The back of the panels can usually be fixed directly to the exterior walls of buildings, or fixed to the keels of the exterior walls of buildings through back ribs. When the panels are manufactured, the front and back of the panels are sprayed with UV glue (also called UV paint, a waterproof coating) by equipment for waterproof treatment to enhance the waterproof performance of the panels. However, for the four sides of the panels, since the sides of the panels are in the shape of thin strips, there is currently no special equipment for spraying UV glue on the sides. In addition, since the surface area of ​​the sides is small, and when the panels are installed and used, the gaps between the side panels are filled with waterproof glue, so the existing panels are usually not UV treated on the sides during manufacturing.

[0003] However, after the building panels are installed on the wall, the waterproof glue between the panels will also age due to long-term exposure to rain and sun. When the waterproof glue in the gaps between the panels ages, moisture can easily penetrate into the panels from the sides, eventually causing the panels to swell and fall off locally. As people have higher and higher requirements for the quality of buildings, the panels need to be UV-sealed on the sides during production. Currently, UV glue is usually applied manually. For a panel with a size of 2m*2m, the total length of the side reaches 8 meters. Manual painting is inefficient, and the painting process is uneven, which can easily lead to partial missing parts, thus affecting the waterproof performance of the side of the panel. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides an automatic sealing device for the side of the decorative panel, which can automatically apply sealing glue to the side of the decorative panel, has high processing efficiency, and effectively improves the waterproof performance of the decorative panel.
