1: Place the tubular plastic part on the conveyor belt 14, start the motor to drive the motor 84, the drive motor 84 drives the drive shaft 12 to rotate, thereby driving the rotating bevel gear 85 to rotate, and the rotating bevel gear 85 drives the revolving gear 86 to rotate to drive the transport shaft 16 Rotation, thereby driving the transport pulley 15 to rotate, the transport pulley 15 rotates to drive the driven pulley 80 and the driven pulley shaft 81 to rotate through the transport belt 14, the transport belt 14 on the upper end of the transport pulley 15 thus moves to the right, and the transport belt 14 Drive the tubular plastic part to move to the right;

2: The rotation of the drive shaft 12 drives the centrifugal mechanism 24 to rotate, and the centrifugal block 90 in the centrifugal mechanism 24 moves in the direction away from the driving gear 23 by centrifugal force. The centrifugal spring 91 is stretched, and the centrifugal block 90 moves to push the translation block 28 to move to the right, The translation block 28 tightens the control rope 29, so that the pressing block 36 is lowered and the vertical spring 32 is compressed, and the driving shaft 12 rotates to drive the driving gear 23 to rotate, thereby driving the transmission gear 42 and the transmission shaft 43 to rotate, thereby driving the lifting friction on the upper side The wheel mechanism 44 and the driven shaft 45 rotate, and the driven shaft 45 drives the eccentric wheel 47 to rotate. Under the elastic force of the compressed control spring 50, the control block 48 performs horizontal reciprocating motion, thereby driving the control rod 49 and the cutting block 55 to reciprocate horizontally. When the cutting block 55 moves to the proper position, manually press the vertical triangular block 34, the vertical triangular block 34 descends to move the pressing cavity 35 to the right, thereby driving the pressing baffle 38 to move to the right and compressing the pressing spring 39, and the pressing The plate 38 moves to the right to loosen the lifting rope 40, so that the upper lifting friction wheel mechanism 44 is lowered and the transmission gear 42 is not meshed, so that the upper lifting friction wheel mechanism 44 and the driven shaft 45 are not rotating, and the eccentric wheel 47 is not rotating. The control block 48 and the cutting block 55 are not moving, so as to control the length of the cutting tubular plastic part;

3: The conveyor belt 14 drives the tubular plastic part to move to the right, contacts the translation stopper 62 and pushes the translation stopper 62 to the right, and the translation stopper 62 moves to the right to drive the connecting plate 63 and the moving block 64 to move to the right and make The reset spring 65 is compressed, and the connecting plate 63 moves to the right to loosen the reset rope 66, so that the lower lifting friction wheel mechanism 44 moves downward under the action of its own gravity to mesh with the rotating gear 73, and the drive shaft 12 drives the drive bevel gear 13 to rotate. Therefore, the driving bevel gear 83 is driven to rotate, thereby driving the driving shaft 82 to rotate, thereby driving the transmission bevel gear 75 to rotate, thereby driving the driven bevel gear 74 to rotate, thereby driving the control shaft 77 to rotate, and the lower lifting friction wheel mechanism 44 rotates The gear 73 is meshed, and the control shaft 77 drives the lower lifting friction wheel mechanism 44 to rotate, thereby driving the rotating gear 73 to rotate, thereby driving the rotating shaft 72 to rotate, and the rotating shaft 72 drives the rotating bevel gear 70 to rotate, thereby driving the rotating bevel gear 87 to rotate, Therefore, the downward movement shaft 71 is driven to rotate, and the downward movement shaft 71 drives the downward movement gear 69 to rotate, thereby driving the fixed rack 67 to move downward, and the downward movement of the fixed rack 67 drives the lifting plate 52 to move downward. Since the fixed plate 51 is fixedly connected There is a gap between the lower pressing plate 97 and the upper end wall of the lifting plate cavity 54 in the lifting plate 52, so the lifting plate 52 first drives the fixing plate 51 to move downward, thereby driving the pressing plate 99 to move downward, thereby driving the pressing block 17 Move downward to compress the tubular plastic part. When the tubular plastic part is pressed, the pressing plate 99 continues to move downward. At this time, the compression spring 20 is compressed and the tubular plastic part will not be compressed and deformed, and the lifting plate 52 drives down. The pressing plate 97 moves downward, and the lower pressing plate 97 drives the lower pressing block 59 to move downward, thereby driving the working block 57 to move downward, thereby driving the working motor 61, the working shaft 60, and the blade 58 to move downward. At this time, the working motor 61 drives the work The shaft 60 rotates, and the working shaft 60 drives the blade 58 to rotate, so that the blade 58 rotates while moving downward to complete the cutting of the tubular plastic part;

4: After the tubular plastic part is cut, it falls into the collection cavity 79, and the translation stopper 62 is no longer pressed to the right side. Under the elastic force of the compressed return spring 65, the moving block 64 and the connecting plate 63 move to the left, thereby pushing The translation block 62 moves to the left to restore the initial position, and the moving block 64 moves to the left to tighten the reset rope 66, so that the lower lifting friction wheel mechanism 44 rises and does not mesh with the rotating gear 73, and no longer drives the rotating gear 73 to rotate, and the rotating shaft 72 no longer rotates, the lifting plate 52 rises to the original position under the elastic force of the compressed support spring 68, thereby driving the fixed plate 51, the pressing plate 99, the pressing block 17, the lower pressing plate 97, the lower pressing block 59 and the working block 57 Return to the original position, the pressing block 17 is not fixing the tubular plastic part, the tubular plastic part continues to move forward under the drive of the conveyor belt 14, and the next cutting is performed. The centrifugal mechanism 24 no longer rotates, and the centrifugal block 90 in the centrifugal mechanism 24 is no longer subjected to centrifugal force. Under the elastic force of the stretched centrifugal spring 91, it moves to the side close to the driving gear 23 and returns to its original position, and the centrifugal block 90 no longer pushes the translation block. 28. Under the elastic force of the compressed horizontal spring 27, the translation block 28 moves to the left to return to the original position, and the translation block 28 moves to the left to relax the control rope 29. Under the elastic force of the compressed vertical spring 32, the pressing block 36 moves upward and returns to its original position, and the upward movement of the pressing block 36 pushes the vertical triangular block 34 to move upward no longer against the horizontal triangular block 33.
