Many modern homes use formed panels. Many formed panels are used for direct interior decoration. Therefore, the surface of many formed panels is required to be smooth and smooth. Many companies have to carry out surface paint treatment on the surface of formed panels. Generally, curtain drenching machines are used for drenching paint. Now the main problems of drenching machines in the drenching process are: 1. There is a certain temperature difference between the surface of the board and the temperature of the paint coating, and tiny air bubbles are likely to be generated after direct drenching, which affects the surface quality. ;2. The speed of the paint coating is not uniform during the process of descending the curtain, and it is easy to splash and cause uneven application; 3. The plate is easy to deviate during transmission

Embodiment Construction
[0025] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0026] Such as Figure 1 to Figure 6 As shown, a panel coating process using an automatic curtain drenching machine for coating. The drenching machine includes a conveyor belt 11 on which the panels 6 are horizontally transported. In this scheme, the panels are transported from right to left, and a shower curtain is set above the conveyor belt. Device 2, the shower curtain device pours the paint onto the surface of the board in the form of a film. There are two conveyor belts described in this plan, and a paint recovery tank 31 is arranged in the middle of the two conveyor belts. The curtain shower device is located directly above the paint recovery tank, because the paint It is a continuous decline, so when the plate does not pass under the curtain device, the falling paint is directly received by the paint recovery tank, and there will be no was...

The invention discloses a plate coating technology based on an automatic flow coating machine. The plate coating technology has the advantages that in the flow coating process, a single circulating system is arranged for coating, and the waste amount of the coating is less; a plate is pre-cooled by a cooling roller before flow coating, and the coating descends to the middle part of the plate and is pre-heated, so the temperature of oil paint is similar to the temperature of the plate in the normal flow coating process, and the bubbling is avoided; by utilizing the technology, the film coating thickness is uniform, the bubbling is avoided, and the waste amount of the coating in the flow coating process is less.
