The piston rod of the second cylinder (16) pushes the push plate (82) to move. The push plate (82) slides outside the square shaft (11) through the bushing (81). Then the push plate (82) drives the push roller (84) to move through the slider (83) until the push roller (84) touches the end of the forming drum (12) and contacts the curtain (14). Step 3: The piston rod of the second cylinder (16) continues to extend. At this time, the push roller (84) continues to be pushed and folds the curtain (14) in half. The push roller (84) moves in the axial direction of the guide rod (85) through the slider (83) and compresses the second spring (86). Step 4: Then the piston rod of the second cylinder (16) drives the push plate (82) to retract, while the push roller (84) disengages from the curtain (14), and the second spring (86) drives the push roller (84) to reset through the slider (83); Step 5: Start the drive motor (9). The drive motor (9) drives the square shaft (11) to rotate through the connecting sleeve (10). The square shaft (11) then drives the forming drum (12) to rotate through the connecting shaft (13). The square shaft (11) will drive the bushing (81) to rotate, and the bushing (81) will drive the fixing ring (87) to rotate. Since the push plate (82) is restricted by the piston rod of the second cylinder (16), it will not rotate. Step 6: At this time, the first cylinder (4) is started. The piston rod of the first cylinder (4) drives the slide rod (5) to move. The slide rod (5) drives the guide wheel (6) to the edge of the curtain (14). Since the curtain (14) rotates with the forming drum (12), it drives the guide wheel (6) to rotate through friction. At this time, the guide wheel (6) is affected by the reaction force of the curtain (14), causing the slide rod (5) to slide in the piston rod of the first cylinder (4) and compress the first spring (7). Similarly, the elastic force of the first spring (7) will act back on the guide wheel (6). Step 7: Then start the servo motor (31), which drives the positive and negative threaded shaft (32) to rotate. The moving seat (33) is displaced by the threaded movement between the positive and negative threaded shaft (32). Then the moving seat 33 drives the first cylinder (4) to move, so that the guide wheel (6) rolls at the edge of the curtain (14). Then the servo motor (31) reverses. This back and forth rolls the edge of the curtain (14) a second time, making the effect of the curtain (14) more effective when it is wrapped back, and it is not easy for the curtain (14) to be out of loop or folded when wrapped back.
