Description

Technical Field

[0001] The utility model relates to the technical field of rubber. Background Art

[0002] The existing rubber refining machines on the market adjust the distance between a pair of relatively rotating rollers, and drive the left and right bearing seats of the mobile roller through two electric reduction mechanisms to make the roller move radially. The final meshing displacement of the mobile roller needs to be manually checked by the thickness of the rubber on the roller and adjusted repeatedly. There is no numerical display, the thickness of the rubber lagging fluctuates widely, the product stability is low, and the scraper needs to be manually driven to scrape the rubber film of the roller. The degree of automation is low and cannot meet the full-automatic production needs of the equipment. The power unit is driven by a motor to drive a single output shaft reducer. The output shaft of the reducer is connected to the fixed roller through a coupling. The fixed roller and the mobile roller drive the two rollers to rotate relative to each other through a pair of speed ratio gears. The open speed ratio gear transmission has low efficiency, large vibration, high noise, low equipment stability, and safety hazards. Utility Model Content
