[0002] Corrugated cardboard is used in the packaging field. It is light and convenient. Corrugated cardboard needs to be punched during the processing. However, since the structure of corrugated cardboard is relatively soft, punching can easily cause the cardboard to deform and is inconvenient to use.

[0003] At present, a Chinese patent with the announcement number CN210336209U discloses a convenient, fixed and efficient punching device for corrugated cardboard processing, comprising an outer box body, a hydraulic telescopic oil cylinder is fixedly installed on the top of the inner side of the outer box body, a micro motor is fixedly installed on the control output end of the hydraulic telescopic oil cylinder, a drill structure is fixedly installed on the control output end of the micro motor, strip-shaped board entry holes are opened on both sides of the outer box body, a first support plate is fixedly installed inside the outer box body and at the upper end of the board entry hole, a second support plate is fixedly installed inside the outer box body and at the lower end of the board entry hole, and cardboard is placed above the second support plate;

[0004] By spirally adjusting the bolt, the adjusting bolt is tightly pressed on both sides of the upper surface of the cardboard through the buffer washer, and finally a hole can be drilled through a drill bit. Drilling can facilitate the drill bit to drill holes, but because the drill bit needs to move downward along the top of the cardboard to drill holes, the active drill bit will exert a certain pressure on the cardboard when it contacts the cardboard, and the corrugated cardboard as a whole has a certain flexibility, and may produce a certain deformation under the pressure of the drill bit, thereby causing a certain impact on the overall strength of the corrugated cardboard.

[0005] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the drill bit exerts too much pressure on the corrugated cardboard during the drilling process. Therefore, a punching device for corrugated cardboard processing is proposed to solve the above problem. Utility Model Content

[0021] By placing the cardboard body 5 under the support plate 4, the drilling position of the cardboard body 5 is placed directly under the drill bit 2, and the fixed baffle plate 3 acts on the upper surface of the buffer support plate 14 as the drill bit 2 moves, thereby driving the buffer support plate 14 to move downward synchronously, so that the buffer support plate 14 drives the connecting column 12 to move along the inside of the hollow column 11, and then drives the spring 13 to be compressed, so that the compression of the spring 13 buffers the drill bit 2 being pressed downward, reflecting the support effect of the buffer support plate 14 on the drill bit 2.

[0022] Reference Figure 2 and Figure 3The supporting mechanism includes side upright plates 6, which are symmetrically welded at the edges of both sides of the upper surface of the supporting plate 4. A fixing rod 7 is symmetrically welded between the two symmetrical side upright plates 6. A movable block 8 is movably installed on the outer surface of the two fixing rods 7 on the same side. There are circular holes at the edges of both ends of the movable block 8. The outer diameter of the fixing rod 7 is smaller than the inner diameter of the circular hole. One side of the outer surface of the fixing rod 7 is located inside the circular hole. A connecting frame 9 is symmetrically fixed between the two movable blocks 8. A movable plate 10 is movably sleeved on the outer surface of the connecting frame 9. A square hole is opened at the edge of one end of the movable plate 10. The cross-sectional area of ​​the connecting frame 9 is smaller than the cross-sectional area at the opening of the square hole, and one side of the outer surface of the connecting frame 9 is located inside the square hole.

[0023] The movable plate 10 is pulled to drive the movable block 8 to move along the outer surface of the fixed rod 7, and the placement position of the movable plate 10 above the cardboard body 5 is adjusted. At the same time, the hollow column 11 is pulled to move along the outer surface of the movable plate 10, and the placement position of the buffer support plate 14 above the cardboard body 5 is adjusted, so that the buffer support plate 14 is placed at the opening position of the cardboard body 5, which reflects the position adjustment effect of the buffer support plate 14 above the cardboard body 5.

[0024] The implementation principle of the punching device for corrugated cardboard processing in the embodiment of the present application is as follows: by placing the cardboard body 5 under the support plate 4, the drilling position of the cardboard body 5 is placed directly under the drill bit 2, the movable plate 10 is pulled to drive the movable block 8 to move along the outer surface of the fixed rod 7, the placement position of the movable plate 10 above the cardboard body 5 is adjusted, and at the same time, the hollow column 11 is pulled to move along the outer surface of the movable plate 10, and the placement position of the buffer support plate 14 above the cardboard body 5 is adjusted, so that the buffer support plate 14 is placed at the opening position of the cardboard body 5, and the drill bit 2 is pressed down to drill the cardboard body 5, and the fixed rod 7 is pulled to move along the outer surface of the movable plate 10. The fixed baffle plate 3 acts on the upper surface of the buffer support plate 14 as the drill bit 2 moves, thereby driving the buffer support plate 14 to move downward synchronously, so that the buffer support plate 14 drives the connecting column 12 to move along the inside of the hollow column 11, and then drives the spring 13 to be compressed, so that the compression of the spring 13 buffers the drill bit 2 that is pressed downward; compared with the prior art, this solution has the effect of facilitating the reduction of the impact of the drill bit 2 on the cardboard main body 5, reduces the impact effect on the cardboard main body 5 when drilling, solves the problem of deformation of the cardboard main body 5 caused by the drill bit 2, and improves the overall protection effect of the cardboard main body 5 when drilling.
