Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of piano manufacturing and processing, and particularly relates to a curtain coating device for piano plates. Background Art
[0002] The existing curtain coating devices for piano paint (PE paint) basically adopt double knife heads. One group is for PE paint plus initiator, and the other group is for PE paint plus accelerator, and the curtain coating is carried out by means of layer-by-layer superposition mixing. This has great limitations, and the disadvantages are as follows: First, it is blind coating. It cannot distinguish between the parts that need to be coated and the parts that do not need to be coated. Second, the mixing and curing are uneven, and it is easy to have the problem of film wrinkling.
[0003] If it is mixed in advance and then uniformly curtain coated, problems such as the adhesion loss of the paint on the equipment are difficult to accurately allocate the specific dosage, and more PE paint needs to be mixed additionally; and the storage time of the mixed PE paint is relatively short, and generally it cannot be reserved for continued use the next day. Day after day, this undoubtedly greatly increases the production cost. Summary of the Utility Model
