[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1-4 As shown, an embodiment of the present invention proposes a punching device for processing plastic products, comprising a base 1, a vertical plate 2 is fixed on the top of the base 1, a supporting frame 3 for supporting the plastic product is fixed on one side wall of the vertical plate 2, an extrusion assembly 4 for extruding and fixing the plastic product is provided on one side wall of the vertical plate 2 and above the supporting frame 3, a lifting assembly 5 is fixed on one side wall of the vertical plate 2, a box body 6 is installed at the bottom end of the lifting assembly 5, a connecting plate 7 is attached to the bottom of the box body 6, a cutter 8 for punching out the excess part of the plastic product is fixed on the bottom of the connecting plate 7, and a cutting knife 8 for punching out the excess part of the plastic product is fixed on the top of the connecting plate 7. Two trapezoidal plugs 9 are symmetrically fixed, and the side walls of the trapezoidal plugs 9 are provided with a card slot 10. The bottom of the box body 6 is symmetrically provided with two sockets 11 adapted to the trapezoidal plugs 9. Springs 12 are fixed to the inner walls of both sides of the box body 6, and a dial plate 13 is fixed to one end of the spring 12. The side walls of the dial plate 13 are fixed with a trapezoidal card block 14 adapted to the adjacent trapezoidal plug 9. The trapezoidal card block 14 is adapted to the corresponding card slot 10. The top of the box body 6 is symmetrically provided with two through-holes 15 for the dial plate 13 to pass through. A storage box 16 for receiving plastic waste is placed on the top of the base 1.

[0024] When it is necessary to cut off the excess part of the plastic box-shaped product, the plastic box-shaped product is first placed on the supporting frame 3, and then the squeezing component 4 is used to squeeze and fix it, and then the lifting component 5 is used to drive the box body 6 to move downward, so as to drive the cutter 8 to move downward to punch out the excess part of the plastic box-shaped product, and the punched excess part will fall into the storage box 16 for storage. When the cutter 8 is damaged and needs to be replaced or repaired, the disassembly process is to squeeze the two dial plates 13 toward the middle, at this time the spring 12 will be stretched, and the dial plate 13 can drive the corresponding trapezoidal block 14 to move toward the middle, so that the trapezoidal block 14 can be disengaged from the card slot 10 on the corresponding trapezoidal plug 9, so that the trapezoidal plug 9 It can be pulled out from the socket 11 at the bottom of the box body 6, so the cutter 8 together with the connecting plate 7 can be removed from the box body 6. When the cutter 8 needs to be installed, it is only necessary to insert the two trapezoidal plug blocks 9 into the corresponding two sockets 11. During the insertion process, when the inclined surface of the trapezoidal plug block 9 is in contact with the inclined surface of the trapezoidal card block 14, the trapezoidal plug block 9 continues to be inserted inward, which will press the trapezoidal card block 14 to move toward the middle. At this time, the spring 12 will be stretched, and when the top of the connecting plate 7 is in contact with the bottom of the box body 6, the inclined surface of the trapezoidal plug block 9 will be separated from the inclined surface of the corresponding trapezoidal card block 14. At this time, under the elastic force of the spring 12, the trapezoidal card block 14 will move outward, thereby being stuck in the corresponding card slot 10, so that the cutter 8 can be fixed.

[0025] like Figure 1 and Figure 4 As shown, in some embodiments, the extrusion assembly 4 includes a fixed plate 401 fixed to a side wall of the vertical plate 2, a first cylinder 402 is fixed to the bottom of the fixed plate 401, and a pressing plate 403 for extruding plastic products is fixed to the ejection end of the first cylinder 402. Two first telescopic sleeves 404 are symmetrically fixed to the bottom of the fixed plate 401, and the bottom ends of the two first telescopic sleeves 404 are fixedly connected to the top of the pressing plate 403, so that the pressing plate 403 can move more stably in the vertical direction. When the plastic box-shaped product needs to be extruded and fixed, the first cylinder 402 can be started, and the ejection end of the first cylinder 402 will drive the pressing plate 403 to move downward, so that the plastic box-shaped product can be extruded and fixed.

[0026] like Figure 1 and Figure 4As shown, in some embodiments, the lifting assembly 5 includes a mounting plate 501 fixed to a side wall of the vertical plate 2, a second cylinder 502 is fixed to the bottom of the mounting plate 501, and the ejection end of the second cylinder 502 is fixedly connected to the top of the box body 6, and two second telescopic sleeves 503 are symmetrically fixed to the bottom of the mounting plate 501, and the bottom ends of the two second telescopic sleeves 503 are fixed with mounting blocks 504, and the two mounting blocks 504 are respectively fixedly connected to the two side walls of the box body 6, so that the box body 6 can move more stably in the vertical direction. When it is necessary to drive the box body 6 to move downward, the second cylinder 502 can be started, and the ejection end of the second cylinder 502 can be extended to drive the box body 6 to move downward.

[0027] like Figure 3 As shown, in some embodiments, a T-shaped guide rod 17 is provided inside the spring 12, one end of the T-shaped guide rod 17 is fixedly connected to the inner wall of one side adjacent to the box body 6, and the shift plate 13 is slidably mounted on the surface of the corresponding T-shaped guide rod 17 so that the shift plate 13 can move more stably in the horizontal direction.
