At this time, the first annular frame is inserted into the first arc-shaped limit slot to prevent the position of the support shaft from changing. The operation of the first motor drives the first screw to rotate. The rotation of the first screw causes the moving seat to move back and forth along the length direction of the screw through the connecting assembly. The cylindrical positioning frame is fastened to the support shaft through screw holes and bolts. The truncated cone limit frame prevents the position of the roll cloth from changing. When the moving seat drives the roll cloth to move to the first lifting cylinder position, the movement is suspended. The operation of the first lifting cylinder drives the support seat to move up. The two ends of the support shaft are inserted into the second arc-shaped placement slot. At this time, the second annular frame is inserted into the second arc-shaped limit slot to prevent the position of the support shaft from changing. The other end of the support shaft corresponding to the setting position of the annular frame extends through the second arc-shaped placement slot. The extended end of the support shaft is manually put on the cylindrical transmission frame, and the cylindrical transmission frame is fastened by screw holes and bolts. The operation of the second motor drives the active roller to rotate, and the active roller and the driven roller cooperate to realize the cloth export. The operation of the second motor drives the supporting shaft to rotate through the first active pulley, the first driven pulley, and the first belt. The rotation of the supporting shaft assists the cloth export. The operation of the second motor drives the first transmission shaft to rotate through the second active pulley, the second driven pulley, and the second belt. The rotation of the first transmission shaft drives the fan blades to rotate. The sponge layer attached to the cleaning rod is used for cleaning the surfaces on both sides of the cloth. The fan blades blow air to blow out the cleaned debris. The dust exhaust port and the dust collecting box are used for collecting the cleaned debris. The fabric is discharged through the first material guide port, the second material guide port, and the third material guide port in sequence. The operation of the third motor drives the second screw on one side to rotate. The second screw drives the second screw on the other side to rotate through the third driving pulley, the third driven pulley, and the third belt. The rotation of the second screw drives the sliding seat to move back and forth along the length direction of the screw through the connecting component, thereby adjusting the distance between the second lifting cylinders. The horizontal movement of the second lifting cylinder adjusts the horizontal distance between the first material guide roller and the second material guide roller. The movement of the piston rods of the second lifting cylinder and the third lifting cylinder is used to adjust the vertical distance between the first material guide roller and the second material guide roller. The operation of the third motor drives the opening roller to move through the fourth driving pulley, the fourth driven pulley, the fourth belt, the worm wheel, the worm, and the second transmission shaft. The rotation of the opening roller assists in the discharge of the fabric. The design of the material guide roller and the opening roller is used to adjust the tension and width of the fabric. When the roll cloth is used up, the first lifting cylinder moves to move the supporting shaft downward and its two ends are stuck in the first arc-shaped placement grooves, and the first screw rod moves again to move the moving seat. The above operations are repeated to facilitate the replacement and loading of the roll cloth.
