Description

Technical Field

[0001] The utility model relates to a rubber processing device, in particular to an open mill used for rubber compound mixing. Background Art

[0002] Rubber refining refers to the operation of kneading raw rubber or rubber compound with a rubber mixer. Kneading raw rubber alone to improve its plasticity is called plastication. Compounded rubber refers to the rubber compound that is mixed with compounding agents in block, granular and powdered raw rubber in an uncrosslinked state and has fluidity. The rubber compound that is kneaded with compounding agents in a rubber mixer according to the formula is called compounded rubber. Compounded rubber is the blank for manufacturing rubber products, that is, semi-finished products. Therefore, the colloidal dispersion quality of compounded rubber is directly related to the quality of the finished product. At the same time, the viscoelasticity and rheology of compounded rubber directly affect the processing performance of the rubber compound and the processing technology of molding, extrusion, calendering, pressing and other processing in the later production.

[0003] An open mixing mill is an open rubber mixing machine, which is used in rubber factories to prepare plasticized rubber, mixed rubber, or perform hot mixing and molding. The main working parts are two hollow rollers or drilled rollers that rotate inward in opposite directions. The one installed on the operator's side is called the front roller, which can be moved back and forth horizontally by manual or electric action to adjust the roller distance to meet the operating requirements; the rear roller is fixed and cannot move back and forth. The two rollers 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 plasticization or mixing. The open mixing mill is also used in plastics processing and other departments. Utility Model Content
