[0020] The working table 5, power plate 6 and top plate 8 of the die-cutting machine working platform 1 are connected by four fixing columns 7 on all sides. The top plate 8 is fixedly connected to one end of the fixing columns 7 by bolts. The power plate 6 is sleeved in the four fixing columns 7 and moves along the direction of the fixing columns 7. The diameter of the fixing column section between the working table 5 and the power plate 6 is smaller than the diameter of the fixing column section between the power plate 6 and the top plate 8. A spring 4 is provided on the outer sleeve of the fixing column section between the working table 5 and the power plate 6.

[0021] A fixed support block 17 is bolted to one side of the power plate 6 of the die-cutting machine working platform 1, and a speed reducer 12 is bolted to the side away from the power plate 6. The fixed support block 17 has an internal opening. A lower fixed block 18 is bolted to the power plate 6 of the die-cutting machine working platform 1. There are preferably two lower fixed blocks 18, which are respectively fixed on the left and right sides of the power plate 6, and have internal openings. The adjusting mechanism 3 includes an adjusting shaft 13, which passes through the lower fixed block 18 and is rotatably connected to the lower fixed block 18 through a bearing sleeve 16. A limiting groove Ⅱ23 is provided on one side of the adjusting shaft 13. The side of the adjusting shaft 13 with the limiting groove Ⅱ23 passes through the fixed support block 17 and is connected to the key shaft of the speed reducer 12. An adjusting motor 11 is fixedly connected to one side of the speed reducer 12, and the adjusting motor 11 drives the adjusting shaft 13 to rotate.

[0022] The deceleration device 12 is a cross-steering gear.

[0023] A top plate 8 of the working platform 1 of the die-cutting machine is fixedly bolted with upper fixing blocks 21. The upper fixing blocks 21 are preferably two and are respectively fixed on the left and right sides of the top plate 8. The inside of the upper fixing blocks 21 is provided with openings. The power mechanism 2 includes a power shaft 9. The power shaft 9 passes through a lower fixing block 18 and is rotatably connected to the lower fixing block 18 through a bearing sleeve 16. A limiting groove Ⅰ 22 is formed on one side of the power shaft 9. A coupling 15 is sleeved outside the limiting groove Ⅰ 22 of the power shaft 9. The coupling 15 is keyed to the limiting groove Ⅰ 22. One side of the coupling 15 away from the power shaft 9 is fixedly connected with a power motor 10, and the power motor 10 drives the power shaft 9 to rotate.

[0024] The eccentric wheel transmission mechanism 14 includes eccentric wheels 19.

[0026] When a die-cutting device of the present utility model is in use, an adjusting motor 11 drives an adjusting shaft 13 to rotate. Since the adjusting shaft 13 is connected to the eccentric wheel 19 of the eccentric wheel transmission mechanism 14, an eccentric displacement is generated after rotation of the eccentric wheel 19, resulting in an angular deviation between the center lines of the power shaft 9 and the transmission shaft, and changing the vertical distance between the power shaft 9 and the transmission shaft, thereby driving the power plate 6 to move upward or downward. A spring 4 below the power plate 6 will be compressed or restored, which also has a buffering effect. Since the rotation angle of the eccentric wheel 19 is slower after deceleration, the cam displacement angle is smaller after the adjusting shaft 13 rotates, and a higher displacement accuracy can be generated. And because the reduction ratio is large, the adjusting motor 11 can be directly used to lock the adjusting shaft 13, and the locking effect is stable, realizing a fully automatic die-locking effect;

[0027] After adjustment is completed, the power motor 10 is started to drive the power shaft 9 to rotate. After the power shaft 9 rotates, the eccentric wheel transmission mechanism 14 will be driven by the eccentric wheel 19 to generate an up-and-down displacement effect. During the up-and-down displacement process of the eccentric wheel transmission mechanism 14, the power plate 6 will be pushed to move up and down, and the power plate 6 drives the die-cutting tool to complete the work.

[0028] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
