Description

Technical Field

[0001] The utility model relates to the technical field of woven bag production and processing equipment, in particular to a surface coating device for chemical woven bags. Background Art

[0002] The coating film is also called paint film. It is a solid continuous film formed by one or more layers of coating applied on the substrate. Usually the coating film is composed of multiple layers of coating, and the number of coating layers is determined according to the requirements of the object to be coated. Generally, it includes a primer layer, an intermediate coating layer and a topcoat layer. At present, when the surface of chemical woven bags is processed, coating processing will be carried out, and then a coating device is needed.

[0003] The utility model with prior art publication number CN216261631U relates to a double-sided coating device for plastic woven bags, which can evenly apply the coating agent to the outer wall of the coating roller, so that the coating roller evenly applies the coating agent to the outer wall of the woven material to achieve a uniform coating effect. The coating operation can be performed on the upper and lower surfaces of the woven material at the same time, thereby improving the coating work efficiency. The coating agent can be intermittently applied to the outer wall of the coating roller, and the use of the coating agent can be reasonably controlled to avoid unnecessary waste and improve resource utilization.

[0004] However, the above device still has the following problems when in use: its paint guide roller structure is single, and its matching paint spraying mechanism is also single. It is difficult to carry out comprehensive chemical woven bag surface coating work only by applying paint with a brush. At the same time, if the brush structure is soft, the paint cannot be applied efficiently, and if the brush structure is hard, it is easy to damage the surface of the chemical woven bag.
