Description

Technical Field

[0001] The utility model relates to the technical field of inner tube production, in particular to an open milling device for inner tube production. Background Art

[0002] The production of inner tubes requires the use of an open mixing device, which is a rubber mixing machine with exposed rollers used to prepare plasticized rubber, mixed rubber, or for hot mixing and molding. The main working parts are two rollers, which are generally the same size and rotate relative to each other at different speeds. The raw rubber or rubber compound is drawn into the gap between the two rollers as the rollers rotate, and is subjected to strong shearing to achieve the purpose of plasticizing or mixing. In the hot summer, butyl rubber may melt, leaving some rubber sticking to the rollers, which will affect the production of inner tubes.

However, in the above case, it is inconvenient to control the squeezing force of the scraper on the roller. When the squeezing force is too large, it is easy to affect the normal rotation of the roller. Moreover, when the scraper cleans the material adhered to the outside of the roller, the material will also adhere to the scraper and accumulate for a long time, which is easy to affect the normal use of the roller.

[0005] Therefore we propose a kind of inner tube production and use open refining device, can solve the above problems. Utility Model Content
