[0027] By setting the punching cylinder 5, the punching rod 6 and the punching knife 71 in the connecting assembly 7, the punching operation is performed on the cardboard by moving downward, and the setting of the fixing rod 2 and the fixing plate 4 facilitates the fixing function of the punching cylinder 5.

[0028] like Figure 2 - Figure 3As shown, a T-shaped groove 11 is provided on the left and right sides of the front side of the upper surface of the operating platform 1, a clamping assembly 12 is provided on the front side of the upper surface of the operating platform 1, an L-shaped clamping plate 14 is fixedly connected to the rear side of the upper surface of the operating platform 1, a handle 13 is fixedly connected to the middle of the upper surface of the clamping assembly 12 in the horizontal direction, elastic ropes 15 are provided on the left and right sides of the rear side of the clamping assembly 12 in the horizontal direction, and the rear end of the elastic rope 15 is fixedly connected to the horizontal front side of the L-shaped clamping plate 14, the clamping assembly 12 includes an L-shaped plate 121, the L-shaped plate 121 and the L-shaped clamping plate 14 are mirror-imaged, and the left and right sides of the lower surface of the L-shaped plate 121 in the vertical direction are fixedly connected to T-shaped sliders 122, and the outer surface of the T-shaped slider 122 is aligned with the inner surface of the T-shaped groove 11 Sliding connection, a strip 123 is fixedly connected to the lower part of the inner wall of the L-shaped plate 121 in the vertical direction, and rounded corners 124 are arranged on the upper and lower parts of the rear side of the strip 123, and a strip 125 is fixedly connected to the upper part of the inner wall of the L-shaped plate 121 in the vertical direction, and an inclined surface 126 is arranged on the lower part of the rear side of the strip 125. The strips 123 and 125 are respectively identical in structure to the inner wall of the L-shaped clamping plate 14 in the vertical direction and are arranged in a mirror image. Sockets 128 are opened on the left and right sides of the rear side of the L-shaped plate 121 in the horizontal direction, and a fixing bolt 127 is threadedly connected to the upper part of the inner part of the socket 128. The inner part of the socket 128 is plugged with the front end of the elastic rope 15, and the lower end of the fixing bolt 127 overlaps and fixes the outer surface of the elastic rope 15;

[0029] When it is needed, the handle 13 is pulled to make the T-shaped slider 122 slide outward inside the T-shaped groove 11, thereby driving the elastic rope 15 to stretch. At this time, the elastic rope 15 changes from a contracted state to a stretched state. When the L-shaped plate 121 in the clamping assembly 12 moves to an appropriate position, the cardboard is placed on the upper surface of the operating table 1. By loosening the handle 13, the L-shaped plate 121 is pulled to move under the elastic action of the elastic rope 15 after stretching. Due to the action of the L-shaped clamping plate 14 and the L-shaped plate 121, the cardboard is clamped in position, which facilitates the punching operation of the cardboard. The setting of the fixing bolt 127 and the socket 128 facilitates the fixing and limiting of the elastic rope 15. When the length is reached, When the cardboard is long, the fixing bolt 127 is rotated in the opposite direction and separated from the elastic rope 15 to complete the disassembly, so that the L-shaped plate 121 can be removed and disassembled, which is convenient for punching the cardboard of a long length. The arrangement of the strip block 123 and the strip block 125 makes it convenient to clamp and tighten the cardboards of different thicknesses. The space below the strip block 123 is used to place thinner cardboards, and the space formed between the strip block 123 and the strip block 125 is used to place cardboards of relatively medium thickness. The entire L-shaped plate 121 is used to place thicker cardboards. The arrangement of the inclined surface 126 and the rounded corner 124 makes it convenient to use the cardboard, and effectively prevents damage to the edge of the cardboard when it is clamped and fixed.

[0030] like Figure 4 - Figure 5 As shown, the connecting assembly 7 includes a punching knife 71, the upper end of the punching knife 71 is fixedly connected to a fixing seat 1 72, the upper surface of the fixing seat 1 72 is overlapped with an iron sheet 73, the middle of the lower surface of the iron sheet 73 is provided with a through hole 74 that communicates with each other up and down, the lower surface of the iron sheet 73 is provided with square openings 75 that communicate with each other up and down on both sides, the upper surface of the iron sheet 73 is overlapped with a fixing seat 2 76, the upper surface of the fixing seat 2 76 is fixedly connected to the lower end of the punching rod 6, and the middle of the lower surface of the fixing seat 2 76 is fixed Bolts 77 are connected, and arc-shaped rubber protrusions 78 are fixedly connected to the left and right sides of the fixing seat 2 76. The outer surfaces of the bolts 77 and the arc-shaped rubber protrusions 78 are plugged into the inside of the through hole 74 and the square opening 75. A connecting hole 721 is opened in the middle of the upper surface of the fixing seat 1 72. Limiting grooves 722 are opened on the left and right sides of the upper surface of the fixing seat 1 72. The inside of the connecting hole 721 is threadedly connected to the outer surface of the bolt 77, and the inside of the limiting groove 722 overlaps the outer surface of the arc-shaped rubber protrusion 78.

[0031] When the punching knife 71 needs to be disassembled and replaced with a different type of punching knife 71, the punching knife 71 is rotated in the opposite direction. At the same time, the arc-shaped rubber protrusion 78 is squeezed and contracted by the action of the limiting groove 722, thereby causing deformation, thereby facilitating the disassembly of the punching knife 71. The provision of the iron sheet 73 facilitates the stability of the punching knife 71 during installation. Just like the role of screws and springs in the existing technology, the stability effect is enhanced by the provision of the arc-shaped rubber protrusion 78 and the limiting groove 722.

[0032] The working principle of the cardboard positioning punching device for carton packaging processing is described in detail below.

[0033] When it is needed, the handle 13 is pulled to make the T-shaped slider 122 slide outward inside the T-shaped groove 11, thereby driving the elastic rope 15. When the L-shaped plate 121 in the clamping assembly 12 moves to the appropriate position, the cardboard is placed on the upper surface of the operating table 1. When the handle 13 is released, the L-shaped plate 121 is pulled to move under the action of the elastic rope 15, so that the cardboard is clamped in position for convenient punching operation. The arrangement of the strip block 123 and the strip block 2 125 facilitates the clamping and tightening of cardboards of different thicknesses. When the punching knife 71 needs to be disassembled, the punching knife 71 is rotated in the opposite direction. At the same time, the arc-shaped rubber protrusion 78 is squeezed and contracted by the action of the limiting groove 722, thereby causing deformation, thereby facilitating the disassembly of the punching knife 71. The arrangement of the iron sheet 73 facilitates the improvement of the stability of the punching knife 71 during installation.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
