Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of rubber mixing mills, in particular to automatic cleaning equipment for rubber mixing mills. Background Art

[0002] The rubber mixing mill is one of the commonly used equipment in the production process of rubber products. It is mainly used for rubber plasticizing, mixing, sheeting and other processes. During the rubber processing, rubber residues, additives and other impurities will inevitably adhere to the roller surface of the mixing mill. If these impurities are not cleaned in time, it will affect the quality of subsequent products and even cause equipment failure. Therefore, the rubber mixing mill needs to be cleaned.

[0003] The cleaning of the existing rubber mixing mill mainly relies on manual operation, that is, the operator uses tools such as scrapers and wire brushes to clean the roller surface. Manual cleaning is not only slow, but also labor-intensive. At the same time, it is difficult to completely remove stubborn stains on the roller surface by manual cleaning, and it is easy to leave cleaning dead corners, affecting product quality. A large amount of wastewater and waste will be generated during the manual cleaning process, which cannot be cleaned in time, thereby causing pollution to the environment around the rubber mixing mill.

[0004] According to the announcement number: CN219276321U, an automatic cleaning equipment for a rubber mixing mill is proposed, and the main points of its technical solution are: it includes a rubber mixing mill body, an operating table is fixedly installed on one side of the rubber mixing mill body, a PLC controller is fixedly installed on one side of the operating table, and a moving block is arranged on the top surface of the operating table; a cleaning component is arranged on one side of the moving block, and is used to clean the rubber mixing mill body. The rubber mixing mill body, operating table, moving block, mounting hole, electric hydraulic rod, mounting block, first clamping groove, cleaning plate, moving groove, stepper motor, rotating column, rotating groove, adjusting block, threaded hole and PLC controller are used in coordination with each other, so that the cleaning plate can comprehensively scratch and clean the rotating roller of the rubber mixing mill body to prevent the rubber on the surface of the rotating roller of the rubber mixing mill body from solidifying, which makes it difficult to clean the rotating roller of the rubber mixing mill body.

[0005] According to the above introduction, the rubber mixing mill needs to be cleaned during use. The cleaning of the existing rubber mixing mill mainly relies on manual operation, that is, the operator uses scrapers, wire brushes and other tools to clean the roller surface.

A large amount of wastewater and waste will be generated during the manual cleaning process, and it cannot be cleaned in time, thereby causing pollution to the environment around the rubber mixing mill. In order to solve the above-mentioned problems, an improved automatic cleaning equipment for rubber mixing mill is proposed. Utility Model Content
