The output shaft of the main reducer is transmitted to two lower rollers through a set of gears, and the rotation direction of the roller shaft is changed by the main motor. It consists of an upper roller, two lower rollers, a lifting screw, a worm gear and some auxiliary parts. The lifting roller's lifting movement is realized by the lifting screw moving up and down. Durable, firm, low investment, simple operation, widely adapt to various working conditions and environment, convenient maintenance.
