2results about How to "Achieve rotation control" patented technology

This utility model relates to the field of rice processing equipment and discloses a rice processing device with convenient flow rate control. It includes a storage silo, with a feeding pipe fixedly installed at the bottom of the silo. Two rotating shafts are rotatably mounted on the front and rear inner walls of the feeding pipe, and adjusting plates are fixedly mounted on the rotating shafts, the two adjusting plates being adapted to the feeding pipe. A housing is fixedly installed on the front side of the feeding pipe, and a lifting plate is slidably installed inside the housing. A drive seat is fixedly installed at the bottom of the lifting plate, and a moving hole is opened on one side of the drive seat. A moving seat is slidably installed in the moving hole, and two rectangular seats are fixedly installed at the bottom of the moving seat. A drive mechanism is provided between the rectangular seats and the rotating shafts. This utility model has the following advantages and effects: through a dual electric and manual control structure, combined with gear and rack transmission, laser ranging feedback, stirring to prevent accumulation, and intelligent control technologies, it achieves precise adjustment of the feeding flow rate, stable equipment operation, and emergency fault handling, effectively improving rice processing efficiency and quality.

This utility model relates to the field of battery electrode sheets and discloses a self-calibration and positioning device for battery rolling rollers. It includes a positioning platform with a hollow side wall and a lifting frame embedded within it. A top plate is horizontally fixed to the top of the lifting frame. A straight rod is fixedly connected to the top of the positioning platform, and a cylinder is fixedly connected to the middle of the straight rod. A retainer is fixedly connected between the top of the cylinder and the top plate. Slider blocks are sleeved on both sides of the straight rod, and a tripod is hinged to the top of each slider. A connecting seat is hinged to the top of the tripod, and the top of the connecting seat is fixed to the bottom of the top plate. Bearing seats are fixedly connected to the bottom of both sides. This self-calibration and positioning device for battery rolling rollers, by incorporating the lifting frame, achieves stable and adjustable lifting and real-time self-calibration positioning of the upper rolling roller relative to the lower rolling roller, eliminating the need for manual disassembly and assembly. This improves electrode sheet thickness control and solves the problem that traditional drilling positioning structures cannot dynamically adjust the rollers.
