Description

Technical Field

[0001] The invention belongs to the field of processing and manufacturing of synthetic leather, and in particular relates to an opening and closing type spraying mechanism for synthetic leather processing and a spraying process thereof. Background Art

[0002] PU leather is the surface of polyurethane components, which is widely used in the decoration of bags, clothing, shoes, vehicles and furniture. It has been increasingly recognized by the market. Its application range is wide, the quantity is large, and the varieties are many. The quality of PU leather is also good or bad. Good PU leather is even more expensive than genuine leather, and the shaping effect is good and the surface is bright. When preparing the existing synthetic leather, the general structure is composed of a base and a surface layer. The surface layer of polyurethane is sprayed on the upper side of the base cloth to form the basic structure of the synthetic leather. When spraying the surface layer on the base cloth, the base cloth is generally transported through a conveying structure, and then polyurethane is sprayed on the upper side through a spray head. The synthetic leather is formed through the steps of rolling, drying, etc. However, when spraying, the width of different base cloths is generally different. When the base cloth with a smaller width is transported and sprayed, the paint sprayed from the nozzles on both sides above it cannot contact the base cloth, which will cause a waste of raw materials. Therefore, reasonable and convenient adjustment is required. Summary of the invention
