[0004] When using the above technology, it was found that the following technical problems exist in the prior art: the prior art uses hexagon socket bolts to install the creasing knife, and the hexagon socket bolts are twisted for a long time to replace the creasing knife, which will cause the hexagon socket bolts to slip, so the efficiency of replacing the creasing knife is not perfect, and when the creasing knife is die-cutting the paper box, the creasing knife drives the paper box to move, which is not convenient for the creasing knife to quickly detach from the inside of the paper box. For this reason, we designed a creasing knife mold to provide another technical solution to the above technical problems. Utility Model Content

[0005] Based on this, it is necessary to provide an indentation die to address the above technical problems. When the paper box is placed on the top of the bottom plate according to the required indentation position and size, the output end of the electric push rod drives the sliding shaft and the track groove to slide, so that the upper pressure plate drives the cutting mechanism to indent the paper box.

[0027] Embodiment 1

[0028] Referring to Figures 1-4 , an indentation die cutter includes a workbench 1. A bottom plate 3 is fixed to the top end of the workbench 1. An L-shaped support frame 2 is fixed to one side of the top end of the workbench 1. One side of the bottom plate 3 is rotatably connected to an upper pressure plate 4. An electric push rod 6 is fixed to the top end inside the L-shaped support frame 2. The output end of the electric push rod 6 is rotatably connected to a sliding shaft 7. A track groove 5 is fixed to the top end of the upper pressure plate 4. The inner side of the track groove 5 is slidably connected to the upper pressure plate 4. A cutting mechanism is provided between the bottom plate 3 and the upper pressure plate 4;

[0029] When the paper box is placed on the top end of the bottom plate 3 according to the position and size where indentation is needed, the output end of the electric push rod 6 drives the sliding shaft 7 to slide with the track groove 5, so that the upper pressure plate 4 drives the cutting mechanism to indent the paper box;

[0030] The cutting mechanism includes a docking plate 8. The docking plate 8 is fixed to the bottom end of the upper pressure plate 4. The bottom end of the docking plate 8 is fixed to a connecting seat 9 by bolts. The bottom end of the connecting seat 9 is fixed to a fixing plate 16. An indentation knife 13 is slidably connected inside the fixing plate 16;

[0031] By connecting the connecting seat 9 and the docking plate 8 with bolts, adjustment can be made according to the position where the paper box needs indentation, which is convenient for adjusting the indentation knife 13 according to the position where indentation is needed;

[0032] The cutting mechanism includes a limiting component. Limiting components are arranged at both ends of the bottom end of the fixing plate 16;

[0033] The limiting component includes mounting blocks 10. Mounting blocks 10 are fixed to both ends of the bottom end of the fixing plate 16. Sliding plates 12 are slidably connected to both sides inside the mounting blocks 10. A positive and reverse threaded rod 11 is rotatably connected inside the mounting blocks 10. The two sides of the outer side of the positive and reverse threaded rod 11 are respectively threadedly connected to the sliding plates 12. One ends of the two sliding plates 12 close to each other are clamped to the indentation knife 13. Wheels 17 are fixed to both sides of the positive and reverse threaded rod 11 passing through the mounting blocks 10;

[0034] When the paper box is indented for a long time and the indentation knife 13 is worn and close to being scrapped, it is convenient to replace the indentation knife 13 in time to avoid the indentation knife 13 reducing the indentation effect of the paper box. When replacing the indentation knife 13, by rotating the wheel 17 to drive the positive and reverse threaded rod 11 to rotate, the positive and reverse threaded rod 11 drives the two sliding plates 12 to clamp or disengage from the indentation knife 13 in the direction of moving away from or approaching each other, which is convenient for quickly replacing the indentation knife 13;

[0036] When the indentation knife 13 makes an indentation on the paper box, at this time, the indentation knife 13 drives the push plate 14 to press on the paper box. Furthermore, the push plate 14 drives the guide rod 15 to slide with the fixing plate 16, and the spring 18 between the push plate 14 and the fixing plate 16 is compressed elastically. When the indentation of the indentation knife 13 and the paper box ends, to prevent the indentation knife 13 from driving the paper box to move, the elasticity of the spring 18 drives the push plate 14 to press on the paper box, so that the push plate 14 presses the paper box on the top of the bottom plate 3, facilitating the indentation knife 13 to cleanly and quickly disengage from the inside of the paper box, and preventing the rotating upper pressure plate 4 from driving the indentation knife 13 and the paper box to move, thereby improving the practicability of the device.

[0037] The using process of the indentation knife die provided by the present utility model is as follows: When the paper box is placed on the top end of the bottom plate 3 according to the position and size where indentation is required, the output end of the electric push rod 6 drives the sliding shaft 7 to slide in the track groove 5, so that the upper pressure plate 4 drives the butt joint plate 8, the connecting seat 9, the mounting block 10, the left - right threaded rod 11, the sliding plate 12, the indentation knife 13, the push plate 14, the guide rod 15, the fixing plate 16, the runner 17 and the spring 18 to make an indentation on the paper box;

[0038] When the indentation of the indentation knife 13 and the paper box ends, to prevent the indentation knife 13 from driving the paper box to move, the elasticity of the spring 18 drives the push plate 14 to press on the paper box, so that the push plate 14 presses the paper box on the top of the bottom plate 3, facilitating the indentation knife 13 to cleanly and quickly disengage from the inside of the paper box, and preventing the rotating upper pressure plate 4 from driving the indentation knife 13 and the paper box to move.
