Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, and more particularly to a coating machine head and a coating device. Background Art

[0002] Film coating is a process that uses a coating device to process rolled film, paper and other substrates, and evenly coats the surface of the substrate with materials such as glue, coating or ink with specific functions. It is widely used in the production of industries such as tapes, labels, printed textiles and leather.

[0003] The common coating device has a simple structure, which is supported by the feeding equipment of the coating substrate, and the coating is evenly applied through the cooperation of the coating head and the feeding equipment. There are many coating methods in the existing coating methods, such as extrusion coating, blade coating, transfer coating and micro-concave coating. In order to meet different price requirements, different coating heads need to be used for adaptation. Most of the coating devices with simple structures now have only one coating head, so they can only be processed in one way. When facing different processing requirements, the coating head needs to be disassembled and reinstalled, which consumes working time and is inconvenient for workers to work. Moreover, in addition to the processing method, The requirements of different coating structures are different. During the coating structure, the coated cloth substrate and the coating applied on the substrate will have different specifications and thicknesses, so there are different processing requirements. The common coating device has a fixed structure, and the distance between its coating head and the feeding equipment cannot be adjusted, and coating processes of different thicknesses cannot be performed. In addition, when transporting the cloth substrate, the substrate is fed into the coating device, and the coating device is not completely closed. During the transportation process, foreign matter such as dust and lint floating in the air may fall onto the surface of the substrate, resulting in the material covering the foreign matter on the substrate during the coating process, leaving the foreign matter in the coating, affecting the quality of the finished product after the coating process.
