Description

Technical Field

[0001] The utility model relates to the field of release agent coating, in particular to a polyurethane release agent coating device. Background Art

[0002] Polyurethane release agent is an auxiliary material used in the manufacture of polyurethane products. It can help to easily remove the polyurethane product from the mold after it is cured. This release agent is usually applied to the mold surface in liquid or spray form to reduce the degree of adhesion between the polyurethane and the mold, thereby facilitating the removal of the product. The use of polyurethane release agents can improve production efficiency, reduce losses, and ensure the surface quality of the finished product.

[0003] The existing technology has the following deficiencies: Polyurethane mattresses are bedding made of polyurethane materials. They usually have good support performance and comfort, so they are very popular in the mattress market. In the production process of polyurethane mattresses, a coating device is required to coat the inner wall of the mold with a polyurethane release agent to facilitate the demolding of the polyurethane mattress. The existing coating devices mostly use spraying release agents for coating. During the spraying process, affected by the ambient airflow, the atomized release agent in the mold is easy to overflow the mold with the airflow, and the release agent attached to the outer wall of the mold or the ground is completely useless for the demolding process and belongs to a meaningless redundant loss part. Therefore, the traditional polyurethane release agent coating device has the problem that the sprayed release agent is easy to overflow, resulting in serious waste of release agent.

[0004] Therefore, it is necessary to invent a polyurethane release agent coating device. Utility Model Content
