Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to a device for uniformly coating a mixing film isolation agent with a common sealing rubber ring for water supply and drainage pipes and sewage pipes. Background Art

[0002] Rubber processing is the process of making rubber into rubber products, which usually includes basic processes such as plastication, mixing, calendering or extrusion, molding and vulcanization. The rubber obtained after the molding process has strong plasticity because it has not been vulcanized. Especially at high temperatures, the surface viscosity of the rubber is very high, and it is very easy to stick to each other when stacked. Therefore, people prevent the rubber from sticking to each other by coating the surface of the rubber with a release agent.

[0003] At present, the more common method of coating the release agent is dipping, that is, the film is immersed in the release agent and passed through the release agent, so that the release agent is evenly adhered to the surface of the film. In the production process, it is found that the thickness of the release agent is not easy to control when the release agent is coated on the film by dipping: if too much release agent is applied, it is not easy to air dry, which affects the product quality in the subsequent process; if too little release agent is applied, it cannot effectively prevent the films from sticking to each other.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a device for uniformly coating a mixing rubber sheet and an isolating agent for a universal sealing rubber ring for water supply and drainage pipes and sewage pipes to solve the shortcomings of the prior art. Utility Model Content

[0005] The purpose of the utility model is to avoid the deficiencies of the prior art and to provide a device for uniformly coating a release agent for a general sealing rubber ring mixed rubber sheet for water supply and drainage pipes and sewage pipes. The film to be coated is introduced into the coating frame through a feeding roller installed inside the coating frame, and is guided by a guide wheel to pass through a spraying mechanism and a coating mechanism in sequence, and then dried by a drying frame, and finally discharged from the coating frame. The spraying mechanism can recycle the release agent for spraying, and at the same time, the fan-shaped nozzle with the same width as the rubber strip can spray more comprehensively. The release agent is more evenly coated on the film through the cooperation of the rotating roller and the coating brush in the coating mechanism, and finally the film surface is scraped after being processed by a material-leveling plate, so as to improve the uniformity of the release agent coating and effectively prevent the films from sticking to each other.
