Coating roll assembly of coating machine

Abstract

The invention provides a coating roll assembly of a coating machine, belongs to the technical field of printing and dyeing, and solves the technical problems that the existing coating device is non-uniform in coating, poor in coating effect, poor in adaptability and the like. The coating roll assembly of the coating machine is characterized by comprising an upper roller and a lower roller, the lower roller is axially fixed on a stander in a circumferential rotating manner, the lower roller is arranged in a coating solution trough, the upper roller is axially fixedly arranged right above the lower roller and is against the lower roller in a circumferential rotating manner, the upper roller and the lower roller are parallel to each other, the upper roller is connected with a force application mechanism which is used for enabling the upper roller to contact the lower roller and generating given pressure, and the lower roller is connected with a rotating mechanism capable of driving the lower roller to rotate. The coating roll assembly of the coating machine has advantages of good coating effect, wide application range and the like.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and relates to a coating roller assembly, in particular to a coating roller assembly of a coating machine. Background technique [0002] At present, the surface of base materials such as fabrics and film materials is generally coated with a layer of coating with functions of fire prevention, moisture resistance and sealing to enhance the performance of use. Due to manual brushing, the coating quality and efficiency are low. . In order to solve the above problems, it was found that Chinese patent CN 102019249 A discloses a coating machine, which includes an unwinding roller, a trough, a heating device, and a winding roller, and an anilox roller for coating liquid is arranged above the trough. And the rubber press roller used to transport the BOPET film, and the rubber press roller is located above the anilox roller, the heating device includes several ovens, a preheating oven is arran...

AI Technical Summary

Problems solved by technology

The working principle of the coating machine is to use the rotation of the rubber press roller and the anilox roller to coat the film. Since the relative position of the rubber press roller and the anilox roller is fixed, when it is necessary to adjust the coating of the base material by the lower roller When the cloth is under pressure, the device cannot be realized, and when it is necessary to coat films of different thicknesses, the applicability of the coating machine is limited because the gap between the upper roller and the lower roller is fixed and cannot be adjusted.
