Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figure 2 , Figure 3 , Figure 5 , an embodiment provided by the present invention: An adjustable PVC hollow board cutter includes a door-shaped frame 5, which serves as the main support structure of the cutter. The design of the door-shaped frame 5 provides a stable foundation for the moving cutting of the cutter. Two housings 6 are respectively fixedly connected to the inner walls on both sides of the door-shaped frame 5. A telescopic block 7 is slidably connected inside the housing 6. One end of the telescopic block 7 is fixedly connected to a horizontal pressing plate 8. After the horizontal pressing plate 8 contacts the PVC middle control board, it drives the telescopic block 7 to slide inside the housing 6, and then adjusts the horizontal clamping of the PVC middle control board by sliding the telescopic block 7 left and right once inside the housing 6. A tooth groove column 1 9 is slidably connected to the top of the housing 6. A limit ring 10 is fixedly connected to the outer wall at the bottom of the tooth groove column 1 9. A spring 11 is fixedly connected to the top of the limit ring 10. The tooth groove column 1 9 makes limited up and down movements inside the housing 6 by the mutual extrusion between the telescopic block 7 and the bottom of the tooth groove column 1 9, and the moving range of the tooth groove column 1 9 is controlled by the elastic force of the spring 11.

[0034] Two fixing plates 12 are fixedly connected to the top of the outer shell 6. On the adjacent sides of the two fixing plates 12, two first connecting shafts 13 are fixedly connected. The fixing plates 12 are used to provide support points for the transmission mechanism that connects the horizontal clamping mechanism and the vertical clamping mechanism in series. One end of the two first connecting shafts 13 is fixedly connected to a support ring 14. The inner wall of one of the support rings 14 is slidably connected to a second toothed groove column 15. The first connecting shaft 13 and the support ring 14 provide a sliding basis for the first toothed groove column 9 and the second toothed groove column 15. The bottom of the second toothed groove column 15 is fixedly connected to a vertical pressing plate 16. The PVC hollow plate is longitudinally clamped by the vertical pressing plate 16, so as to perform two-way clamping of the PVC hollow plate in the horizontal and vertical directions, so that the PVC hollow plate remains stable during cutting, and the cutting accuracy is improved.

[0035] On the adjacent sides of the two fixing plates 12, a second connecting shaft 17 is rotatably connected. A first gear 18 is fixedly connected to the outer wall of the second connecting shaft 17. The second connecting shaft 17 provides a rotation basis for the first gear 18. The outer side of the first gear 18 is meshed with the outer side of the first toothed groove column 9, and the outer side of the first gear 18 is meshed with the outer side of the second toothed groove column 15. When the first toothed groove column 9 moves upward, it drives the first gear 18 to rotate and then transmits to the second toothed groove column 15, so that the second toothed groove column 15 moves downward, thereby driving the vertical pressing plate 16 to move downward to longitudinally clamp the PVC hollow plate. An adjusting assembly for adjusting the cutting trajectory and cutting depth of the cutter is fixedly connected to the inner wall of the portal frame 5.

[0036] Refer to Figure 2 、 Figure 3 、 Figure 6 The adjusting assembly includes a pneumatic guide rail 19. The two ends of the pneumatic guide rail 19 are respectively fixedly connected to the left and right inner walls of the portal frame 5. The pneumatic guide rail 19 is used to provide a sliding path for the pneumatic slider 20. A pneumatic slider 20 is slidably connected to the outer wall of the pneumatic guide rail 19. The pneumatic slider 20 horizontally adjusts the horizontal position of the cutter structure by sliding on the pneumatic guide rail 19. A connecting plate 21 is fixedly connected to the bottom of the pneumatic slider 20. A plurality of support columns 22 are fixedly connected to the bottom of the connecting plate 21. The bottom of the plurality of support columns 22 is fixedly connected to a support plate 23. The support columns 22 are used to connect the support plate 23 and the connecting plate 21 and leave a certain space between the support plate 23 and the connecting plate 21. An air pump 24 is fixedly connected to the top of the support plate 23. The air pump 24 is installed between the support plate 23 and the connecting plate 21 to prevent the operation of the air pump 24 from being affected. The output end of the air pump 24 is fixedly connected to a wire cutter 25. The wire cutter 25 is driven by the air pump 24 to move in the vertical direction, so as to control the cutting depth of the PVC hollow plate.

[0037] Two gears two 26 are rotatably connected to the bottom of the portal frame 5. A motor 27 is fixedly connected to the top of one of the gears two 26. The motor 27 is used to drive one of the gears two 26 to rotate, thereby driving the portal frame 5 to move horizontally in the longitudinal direction, so as to control the longitudinal horizontal position of the wire cutter 25, and the other gear two 26 is used to balance the movement of the entire portal frame 5. A sliding column 28 is fixedly connected to the bottom of the gear two 26. A workbench 1 is slidably connected to the bottom of the portal frame 5. The workbench 1 provides a stable support base for the entire cutting adjustment device. Two chute one 29 are opened at the top of both sides of the workbench 1. The outer wall of the sliding column 28 is slidably connected inside the chute one 29. The sliding of the sliding column 28 in the chute one 29 is used to stably carry out the rotation and movement of the gear two 26 at the same time. Two gear grooves 30 are respectively opened on both sides of the top of the workbench 1. The outside of the gear two 26 is meshed with the outside of the gear groove 30, so that the gear two 26 can move axially along the gear groove 30 when rotating. Two sliding plates 31 are respectively fixedly connected to the bottom of both sides of the workbench 1. Two chute two 32 are opened on the top of the workbench 1. The outer wall of the sliding plate 31 is slidably connected inside the chute two 32. The sliding of the sliding plate 31 in the chute two 32 further stabilizes the longitudinal horizontal movement of the portal frame 5.

[0038] Refer to Figure 1 , Figure 2 , Figure 4 , a cutting table 2 is arranged in the middle of the workbench 1. The cutting table 2 provides a cutting support base for the PVC hollow board. A plurality of through holes are opened on the cutting table 2, so that the waste generated by cutting falls through the through holes on the cutting table 2 for convenient collection. A control panel 3 is arranged at one end of the workbench 1, and a control key 4 is arranged at one end of the workbench 1. The cutting of the PVC hollow board by the cutter is conveniently controlled through the control panel 3 and the control key 4. A collecting plate 33 is slidably connected inside the workbench 1. A collecting groove 34 is opened on the top of the collecting plate 33. A handle 35 is fixedly connected to one end of the collecting plate 33. The collecting groove 34 on the collecting plate 33 is used to collect the waste falling from the through holes on the cutting table 2, and the entire collecting plate 33 can be pulled out by pulling the handle 35 to facilitate the recycling treatment of the waste. A plurality of bottom columns 36 are fixedly connected to the bottom of the workbench 1. A base 39 is fixedly connected to the bottom of the bottom column 36. A fixing ring 37 is fixedly connected to the outer wall of the bottom column 36. A plurality of support rods 38 are fixedly connected to the bottom of the fixing ring 37. The bottom column 36 and the base 39 provide a longitudinal supporting force for the entire cutting device, so that the entire device remains stable in the vertical direction, and the fixing ring 37 and the support rods 38 are used to prevent the cutting device from shaking.

[0039] Working principle: When cutting the PVC hollow board, first place the PVC hollow board on the cutting table 2, turn on the motor 27. The operation of the motor 27 drives the rotation of the second gear 26. The rotation of the second gear 26 drives the entire portal frame 5 to move horizontally longitudinally on the workbench 1 through meshing with the gear groove 30. At the same time, the movement of the portal frame 5 is stabilized by the sliding of the sliding column 28 and the sliding plate 31. Since both ends of the transverse pressing plate 8 are arc-shaped, when the transverse pressing plate 8 contacts the PVC hollow board, the two transverse pressing plates 8 move away from each other, thereby driving the telescopic rod to move into the housing 6, and then squeezing the bottom of the first tooth groove column 9, so that the first tooth groove column 9 moves upward. The upward movement of the first tooth groove column 9 drives the rotation of the first gear 18. The rotation of the first gear 18 is transmitted to the second tooth groove column 15, causing the second tooth groove column 15 to move downward, thereby driving the longitudinal pressing plate 16 to clamp the PVC hollow board longitudinally, so as to ensure that the PVC hollow board remains stable during cutting.

[0040] Then turn on the wire cutter 25, the pneumatic slider 20 and the air pump 24. The movement of the pneumatic slider 20 on the pneumatic guide rail 19 drives the wire cutter 25 to move horizontally transversely through the transmission of the connecting plate 21 and the support plate 23, and the operation of the air pump 24 drives the wire cutter 25 to move in the vertical direction, so as to control the cutting depth, and control the operation of the air pump 24, the pneumatic slider 20 and the motor 27 through the control panel 3 and the control keys 4, so that the wire cutter 25 can cut the PVC hollow board into various shapes according to the established program.

[0041] The waste generated by cutting enters the through hole on the cutting table 2 and falls into the collection groove 34 on the collection plate 33. Then, the collection plate 33 can be pulled out by pulling the handle 35 to recycle the waste. At the same time, the vibration stress generated during cutting is borne by the bottom column 36 and the base 39 for the longitudinal vibration stress, while the fixed ring 37 and the support rod 38 are used to bear the transverse vibration stress to keep the entire cutting device stable.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
