[0024] It can be seen from this that when it is necessary to cut the PVC sheet, Figure 1 As shown, the staff places the PVC sheet on the extension platform 21 and pushes the PVC sheet toward the support frame 22. At this time, the PVC sheet is pushed to the bottom of the conveying roller 24, and the conveying roller 24 is driven by electricity to convey the PVC sheet toward the first shielding plate 25. Figure 6 As shown, the first rotating rod 311 and the first rotating wheel 32 rotate together under the drive of the motor 31, and the first rotating wheel 32 drives the second rotating wheel 33 to rotate together through the second transmission belt 321, and the second rotating wheel 33 drives the second rotating rod 331 and the cutting wheel 34 to rotate together, at this time, the PVC sheet is cut under the conveyance of the conveying roller 24, and the PVC sheet is conveyed toward the plate outlet 252 of the first shielding plate 25; It should be noted that when it is necessary to cut plates of different thicknesses, the staff controls on the control panel, and the No. 1 threaded rod 123 rotates under the drive of the external motor, and the No. 1 threaded rod 123 drives the sliding block 13 to slide in the direction of the motor 31, and the sliding block 13 pushes the No. 1 connecting rod 131, at this time the No. 1 connecting rod 131 will pry upward, and the No. 1 connecting rod 131 will drive the rotating plate 12 to rotate upward, and in the process of the rotating plate 12 rotating, the No. 2 fixed column 121, the No. 2 rotating rod 331 and the cutting wheel 34 will be driven to tilt upward, so that the cutting wheel 34 cuts plates of different thicknesses; Example

[0026] From this we can see that Figure 7 As shown, with the rotation of the No. 1 rotating rod 311, the No. 1 bevel gear 41 rotates, and at the same time, the No. 1 bevel gear 41 will drive the No. 2 bevel gear 42 and the No. 3 bevel gear 43 on both sides to rotate together, and the No. 2 bevel gear 42 will drive the No. 1 reciprocating screw rod 421, and similarly, the No. 3 bevel gear 43 will drive the No. 2 reciprocating screw rod 431 to rotate. At this time, the rotation of the No. 1 reciprocating screw rod 421 will drive the No. 3 sliding column 422, the No. 2 sliding column 142 and the No. 1 baffle plate 25 to slide toward the direction of the support frame 22. When the No. 1 baffle plate 25 slides to the bottom of the upper limit block 23 of the support frame 22, the buckle 251 is squeezed and pressed down. After the component 251 rebounds, the No. 2 sliding column 142 slides to the end of the No. 1 reciprocating screw rod 421 and slides toward the No. 2 bevel gear 42 again. At this time, the No. 1 baffle plate 25 will be affected by the buckle component 251 to drive the support frame 22 to slide toward the No. 2 baffle plate 26. At this time, the conveying roller 24 slides toward the No. 2 baffle plate 26 together with the conveying PVC board and the support frame 22. At this time, the PVC board is cut when passing through the cutting wheel 34 and is blocked by the No. 1 baffle plate 25, so that the debris is blocked on the inner side of the No. 1 baffle plate 25, and the cleaning rod installed between the support frames 22 is cleaned and brought into the space between the No. 2 baffle plates 26 together; It should be noted that in the process of the No. 1 reciprocating screw 421 driving the No. 1 baffle plate 25 to slide, when the No. 1 baffle plate 25 slides to the position of the support frame 22, it will drive the support frame 22 to slide together through the fastener 251. At this time, the No. 1 baffle plate 25 will slide synchronously with the support frame 22. When the No. 1 baffle plate 25 slides to the position of the support frame 22, the support frame 22 has begun to transport and cut the inner plate. At this time, the position of the No. 1 baffle plate 25 is in the middle position to block the debris. During the cutting process, the No. 1 baffle plate 25 will always be in the rear half of the plate together with the support frame 22 toward the No. 2 baffle plate 26. Then the rear half will block the cutting debris of the rear half of the plate during the cutting process.
