Detailed implementation manners

[0033] 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.

[0034] An embodiment of the present application discloses a punching mechanism that can avoid the collapse of thick materials. There is a base 1, and two support frames 2 are installed at the top end of the base 1. Fixed components are installed inside both of the two support frames 2;

[0035] Both of the two fixed components include a first motor 3. The output end of the first motor 3 is installed with a lead screw 4. The outer side of the bottom end of the lead screw 4 is installed with a movable plate 9. Two limiting rods 8 are fixedly connected inside the movable plate 9. The bottom ends of the two limiting rods 8 are fixedly connected with a pressing plate 6. A connecting rod 5 is fixedly connected between the two pressing plates 6. Rubber pads 7 are fixedly connected to the bottom ends of the two pressing plates 6. Bottom plates 10 are arranged at the bottoms of the two pressing plates 6. Second chutes 22 are opened at both ends inside the base 1. By driving the lead screw 4 to rotate with the first motor 3, the lead screw 4 can drive both ends of the movable plate 9 to slide inside the second chute 22. The two second chutes 22 can provide a supporting force for the movement of the movable plate 9. The movement of the movable plate 9 drives the two limiting rods 8 to move inside the top end inside the base 1. The base 1 is used to provide a limit for the movement of the two limiting rods 8, facilitating the movement of the two limiting rods 8 to maintain stability. The two limiting rods 8 can simultaneously drive the pressing plate 6 to move. Both of the two pressing plates 6 drive the rubber pads 7 to cooperate with the bottom plate 10, facilitating the clamping and fixing of both sides of the material, and effectively preventing the collapse phenomenon of the material during the punching process, enhancing the stability of the material during the punching process.

[0036] Refer to Figure 2 As shown, one side of the top end of the base 1 is fixedly connected with a hydraulic lifting rod 11, and a punching machine body 12 is installed outside the hydraulic lifting rod 11. By the punching machine body 12 moving outside the hydraulic lifting rod 11, it is convenient for the punching machine body 12 to move up and down, so as to punch the material.

[0037] Refer to Figure 4 And6 As shown, a collection groove 13 is provided in the middle of the top end of the base 1. A first sliding groove 14 is provided on one side inside the collection groove 13. A second motor 15 is installed on one side inside the base 1. A gear 16 is installed at the output end of the second motor 15. A rotating rod 17 is fixedly connected to one side of the gear 16. A cleaning rod 18 is fixedly connected to the outside of the rotating rod 17. A slider 19 is fixedly connected to one end of the cleaning rod 18. The second motor 15 is used to drive the gear 16 to rotate, so that the gear 16 can drive the cleaning rod 18 to rotate through the rotating rod 17, thereby cleaning the debris inside the collection groove 13. The slider 19 slides inside the first sliding groove 14, so as to support the cleaning rod 18 to move left and right inside the collection groove 13.

[0038] Refer to Figure 4 As shown, a rack 20 is fixedly connected to one end inside the base 1. A waste material groove 21 is connected to the rear side of the collection groove 13. The top of the rack 20 is meshed with one side of the gear 16, which is convenient for the gear 16 to drive the cleaning rod 18 to move left and right inside the collection groove 13. The waste material groove 21 is used to centrally collect the debris cleaned by the cleaning rod 18, thereby optimizing the working environment of the base 1.

[0039] Working principle of the present utility model: The present utility model designs a punching mechanism that can avoid the collapse of thick materials at the edges. The specific structure is as shown in the attached Figures 1-6 As shown in the figure. In this technical solution, through the mutual cooperation between various structures, when punching materials, first place the materials on the two bottom plates 10, and then start the two first motors 3. The first motors 3 are used to drive the lead screws 4 to rotate, so that the lead screws 4 rotate to drive the movable plate 9. The movable plate 9 slides inside the second sliding grooves 22 on both sides. The two second sliding grooves 22 provide support for the movement of the movable plate 9. At the same time, the movement of the movable plate 9 drives the two limiting rods 8 to move downward inside the base 1. The base 1 can provide stability for the two limiting rods 8. The two limiting rods 8 drive the pressing plates 6 to move downward. The two pressing plates 6 drive the rubber pads 7 to move downward to clamp and fix the materials with the bottom plates 10. Then start the punching machine body 12, and punch the materials through the punching machine body 12. When punching generates debris, start the second motor 15. The second motor 15 is used to drive the gear 16 to rotate, so that the gear 16 drives the rotating rod 17 to rotate. Thus, the rotating rod 17 can drive the cleaning rod 18 to rotate inside the collection groove 13. While the gear 16 rotates, it can be meshed with the top of the rack 20, so as to drive the cleaning rod 18 to move left and right inside the collection groove 13. The cleaning rod 18 slides inside the first sliding groove 14 through the slider 19, which is convenient for supporting the cleaning rod 18 to move inside the collection groove 13. The rotation of the cleaning rod 18 inside the collection groove 13 can sweep the debris generated by punching into the waste material groove 21, so as to keep the outside of the base 1 clean.
