Abstract

The invention belongs to the technical field of coating machines, and particularly relates to a dual-face coating machine. The dual-face coating machine comprises an air flotation via roller. The airflotation via roller comprises a hollow roller body and an air volume rectifier. The air volume rectifier is fixed into the hollow roller body. An air inlet of the air volume rectifier communicates with an air pipe, and the air pipe is connected with the hollow roller body. The air volume rectifier is provided with multiple first through holes. Gas of the air volume rectifier enters an inner cavity of the hollow roller body through the multiple first through holes. Multiple second through holes are formed on the roller face of the hollow roller body and are evenly arranged in a staggered manner.

Description

technical field [0001] The invention belongs to the technical field of coating machines, in particular to a double-sided coating machine. Background technique [0002] Existing coating machines use plastic guide rollers or metal guide rollers to realize the function of suspending and guiding the substrate to move on the coating machine through mechanical contact. However, in the process of double-sided coating, the plastic guide rollers or metal guide rollers directly contact The substrate will damage the undried coated side. In order to solve the above problems, the patent application publication number CN 105188958A discloses a double-sided coating machine, which supports the substrate by clamping the uncoated area. However, due to the small supporting area, It is difficult to achieve complete support for the substrate, and the substrate is prone to deviation during high-speed coating. Contents of the invention [0003] In view of this, the present invention provides a...
