The pressure connecting rod 6 further transmits the pressure to the distribution plate 5. The distribution plate 5 distributes the pressure evenly or as needed onto the upper roller shaft 2. The motor 13 is started, and the drive end of the motor 13 drives the fixed plate 18 to rotate. The rotation of the fixed plate 18 causes the elastic top plate 16 to push the pawl 17 to engage the inner ratchet 15.

When it is necessary to reverse the upper roller shaft 2, the motor 13 is stopped. At this time, the elliptical plate 14 rotates in the opposite direction with the reverse rotation of the upper roller shaft 2. Since the power of the motor 13 is lost, the inner ratchet 15 will not be engaged by the pawl 17 during the reverse rotation, allowing the elliptical plate 14 to rotate freely. During the reverse rotation, the pressure of the elliptical plate 14 on the upper roller shaft 2 decreases, which reduces the force of the reverse rotating motor 24, thereby reducing energy consumption.
