While the horizontal plate moves downward, it compresses the elastic pad through the vertical rod and the pressure plate, and makes the pressure pad pressed tightly against the outer side of the conveyor roller. At the same time, the horizontal plate moves to the left, thereby driving the conveyor roller to move to the left. The upward movement of the horizontal plate reduces the compression degree of the elastic pad, so that the pressing force of the pressure pad on the conveyor roller is reduced. The horizontal plate continues to move upward, causing the pressure pad to disengage from the conveyor roller, so that the horizontal plate moving to the right will not drive the conveyor roller to move to the right, thereby driving the horizontal plate to continue to move in a counterclockwise circular motion, thereby intermittently pushing the conveyor roller to the left until it is released from the baffle, thereby squeezing the baffle to the left, and sensing the pressure value through the pressure sensor.

At the same time, the rotating motor is started to drive the driving gear to rotate, and the driving gear drives the outer gear ring to rotate by meshing with the outer gear ring, and drives the movable base and the cutting blade to perform circular motion, thereby realizing the cutting work at different circumferential positions of the conveying roller, thereby realizing automatic fixed-length cutting of the conveying roller. After the cutting is completed, the electromagnet is energized and started, thereby generating magnetic attraction to the iron sheet, and driving the square plate and the baffle to move downward, thereby contacting the obstruction of the conveying roller, and then starting the driving motor to continue to intermittently push the conveying roller to the left to move left, thereby realizing the discharge of the cut conveying roller, and driving the adjusting plate to move horizontally by starting the cylinder, thereby driving the baffle to move horizontally, thereby realizing the adjustment of the cutting length;
