When the second motor 33 is operated, the second transmission shaft 31 is fixedly connected with the output shaft of the second motor 33, the second transmission shaft 31 starts to rotate, the second universal joint 30 is fixedly connected with the second transmission shaft 31, the rotation of the second transmission shaft 31 drives the second universal joint 30 to rotate, the first universal joint 29 is fixedly connected with the second universal joint 30, the rotation of the second universal joint 30 drives the first transmission shaft 28 to rotate, the first transmission shaft 28 is fixedly connected with the transmission gear 27, the rotation of the first transmission shaft 28 drives the transmission gear 27 to rotate, the transmission gear 27 is in meshing transmission with the arc-shaped rack 26, the rotation of the transmission gear 27 drives the arc-shaped rack 26 to rotate along the circle center direction of the rotating disc 19, because the arc-shaped rack 26 is fixedly connected with the rotating disc 19, the rotation of the arc-shaped rack 26 drives the rotating disc 19 to rotate, and during the meshing process of the transmission gear 27 and the arc-shaped rack 26, one end of the transmission gear 27 is fixedly connected with the first transmission shaft 28, the other end of the arc-shaped rack 26 extends into the rotating disc 19 to abut against the arc-shaped groove 20, at this time, since the two sides of the arc-shaped rack 26 are both provided with the meshing teeth, the transmission gear 27 can move along the two sides of the arc-shaped rack 26, and when the transmission gear 27 moves to the end part of the arc-shaped rack 26 each time, the arc-shaped rack 26 starts to rotate reversely under the meshing action of the transmission gear 27. The rotating disk 19 fixedly connected with the arc-shaped rack 26 rotates reversely, and in the whole process, the linkage disk 21 rotates once along with the rotating disk 19 and regulates the rotation to be positive rotation, and then rotates once again along with the rotating disk 19 to be negative rotation, and when the linkage disk 21 rotates, the cutting mechanism 38 and the linkage disk 21 are fixedly installed, so that the cutting mechanism 38 operates and cuts the PVC-C plastic pipe, and the specific cutting process is as follows: the output ends of the two laser cutting instruments 39 are aligned with the outer wall of the PVC-C plastic pipe for cutting, and along with the rotation of the cutting mechanism 38 along the circumferential direction of the PVC-C plastic pipe, the two laser cutting instruments 39 complete the processing of the PVC-C plastic pipe in the circumferential direction, and the reason for arranging the two laser cutting instruments 39 is that: because the angle of each rotation of the arc-shaped rack 26 is less than 360 degrees, if only one laser cutting instrument 39 is provided, one laser cutting instrument 39 can cut a part of the PVC-C plastic pipe in a missing manner, and two laser cutting instruments 39 are provided, wherein one laser cutting instrument 39 finishes the cutting processing of the major arc part of the outer wall of the PVC-C plastic pipe, the other laser cutting instrument 39 finishes the cutting processing of the minor arc part of the outer wall of the PVC-C plastic pipe, namely the two laser cutting instruments 39 are mutually matched to finish the cutting of the outer wall of the PVC-C plastic pipe at 360 degrees, and through the program setting, in the working process of the laser cutting instruments 39, when the moving direction of the reciprocating movement component 3 is the same as the extrusion direction of the PVC-C plastic pipe, the two laser cutting instruments 39 start to work, and at the moment, the two laser cutting instruments 39 cut the PVC-C plastic pipe, when the moving direction of the reciprocating motion assembly 3 is opposite to the extrusion direction of the PVC-C plastic pipe, the linkage disc 21 reverses at the moment because the cutting work is finished, the two laser cutting instruments 39 stop working, and the PVC-C plastic pipe is prevented from being processed mistakenly in the reversing process of the linkage disc 21. In the rotating process of the transmission gear 27, due to the reciprocating rotation movement of the arc-shaped rack 26, the transmission gear 27 can perform reciprocating movement in the vertical direction, so that the first transmission shaft 28 connected with the transmission gear 27 can also perform reciprocating movement in the vertical direction, the limiting slide block 35 is sleeved on the outer side of the first transmission shaft 28, when the first transmission shaft 28 performs reciprocating movement in the vertical direction, the limiting slide block 35 also performs reciprocating movement in the vertical direction, in the moving process of the limiting slide block 35, the two limiting shafts 34 provide limiting for the movement of the limiting slide block 35, it is ensured that the moving path of the limiting slide block 35 is in the vertical direction, the support base 36 is used for fixing the bottom ends of the two limiting shafts 34, and the limiting and anti-falling plate 37 is used for fixing the top ends of the two limiting shafts 34. And the first universal joint 29 and the second universal joint 30 ensure that the first transmission shaft 28 can receive power provided by the second motor 33 and can move back and forth in the vertical direction at the same time. Throughout the process, the rotating disc 19 is designed to rotate back and forth because the electrical wires of the laser cutting apparatus 39 are connected to a power source (which is conventional and not shown), and if the rotating disc 19 rotates 360 ° in one direction, the electrical wires become entangled and cause a safety hazard and prevent the rotating disc 19 from further rotating.

The specific working process of the reciprocating component 3 is as follows: when the first motor 6 runs, the driving gear 7 is fixedly connected with an output shaft of the first motor 6, the driving gear 7 is meshed with the two driven gears 8, the driving gear 7 drives the two driven gears 8 to rotate, the two driven gears 8 are fixedly connected with the two driven stub teeth 9, the rotation of the two driven gears 8 drives the two driven stub teeth 9 to rotate, at the moment, because the two driven stub teeth 9 are meshed with the transmission rack 10, when one driven stub tooth 9 is meshed with the transmission rack 10, the driven stub teeth 9 can push the transmission rack 10 to the extrusion direction of the PVC-C plastic pipe, after the driven stub teeth 9 are meshed with the transmission rack 10, the transmission rack 10 stops moving, at the moment, the other driven stub tooth 9 is meshed with the transmission rack 10, and along with the meshing of the driven stub teeth 9 and the transmission rack 10, the driven stub teeth 9 can push the transmission rack 10 to the extrusion direction of the PVC-C plastic pipe, the two driven residual teeth 9 are mutually matched to complete the reciprocating movement of the transmission rack 10. When the transmission rack 10 reciprocates, the connecting plate 11 is fixedly connected with the transmission rack 10, the reciprocating motion of the transmission rack 10 drives the connecting plate 11 to move, the connecting plate 11 is connected with the fixed plate 12, the moving of the connecting plate 11 drives the fixed plate 12 to move, the fixed plate 12 is fixedly connected with the upper ends of the two first supporting plates 13, the moving of the fixed plate 12 drives the two first supporting plates 13 to move, the inner sides of the lower ends of the two first supporting plates 13 are fixedly connected with the moving platform 17, the moving of the two first supporting plates 13 can drive the moving platform 17 to move, in the moving process, in order to ensure the fluency of the moving process, the two reciprocating sliders 16 are respectively and fixedly connected with the outer sides of the lower ends of the two first supporting plates 13, in the moving process, along with the moving of the two first supporting plates 13, the two reciprocating sliders 16 reciprocate in the slide rails 14, and the slide seat 15 is fixedly installed at the upper end of the supporting platform 2, the fixed connection between the slide rail 14 and the slide carriage 15 can ensure that the two reciprocating sliders 16 can reciprocate along the slide rail 14, and the cooperation between the reciprocating sliders 16 and the slide rail 14 can improve the fluency when the reciprocating assembly 3 reciprocates. The gear rack structure is adopted in the reciprocating movement so as to ensure that the movement is kept at a constant speed in the moving process, the moving speed of the transmission rack 10 is the same as the extrusion speed of the PVC-C plastic pipe, when the speeds of the transmission rack and the PVC-C plastic pipe are the same, the rotating disc 19 and the PVC-C plastic pipe can be kept relatively still, and the cutting assembly can be used for completely cutting the PVC-C plastic pipe in the circumferential direction. The advancing speed of the reciprocating mechanism 4 can be matched with the extrusion speed of the PVC-C plastic pipes, so that the PVC-C plastic pipe processing device is suitable for PVC-C plastic pipe processing devices with different extrusion speeds.
