[0020] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Please refer to the attached Figures 1-5 For the axial adjustment device of the high-speed circular knife die-cutting machine provided by the present utility model, it includes a base 1. At both ends of the top of the base 1, support frames 2 are symmetrically fixed. At the top of the side end of the support frame 2, a first reduction motor 3 is fixed. It should be noted that a reduction motor is a motor that converts high-speed input into low-speed output, and is composed of a motor and a reducer. The motor is responsible for providing power, and the reducer reduces the high-speed rotating output of the motor to the required low speed through a series of internal gear transmissions or other transmission mechanisms. The output shaft of the first reduction motor 3 passes through the support frame 2, and a roller 4 is fixed on the output shaft of the first reduction motor 3. The surface of the roller 4 is connected with a plurality of circular blades 5 through an axial adjustment component. That is, when the first reduction motor 3 operates, a plurality of circular blades 5 can be driven to rotate by the roller 4. A feeding roller 6 is connected to the support frame 2 through a height adjustment component. An auxiliary adjustment component is arranged at the top of the support frame 2, and the auxiliary adjustment component is located directly above the plurality of circular blades 5, and the feeding roller 6 is located directly below the plurality of circular blades 5;

[0022] The axial adjustment component includes a plurality of annular connection blocks 7. A plurality of circular blades 5 are respectively fixed on the outer ring surfaces of the plurality of annular connection blocks 7. Horizontally symmetric sliding grooves 8 are opened on the surface of the roller 4 up and down. On the inner ring surfaces of the annular connection blocks 7, sliding blocks 9 are symmetrically fixed up and down. The sliding blocks 9 slide in the sliding grooves 8. That is, a plurality of circular blades 5 can linearly reciprocate horizontally on the surface of the roller 4 through the corresponding annular connection blocks 7, that is, the circular blades 5 can move axially;

[0023] The axial adjustment component further includes an annular fixing block 10. The side end of the annular fixing block 10 is fixed to the side end of the annular connection block 7. Threaded holes 11 are symmetrically opened at the upper and lower ends of the annular fixing block 10. The threaded holes 11 are threadedly connected with tightening bolts 12 on the hole walls. The ends of the tightening bolts 12 are abutted against the inner surface of the sliding groove 8. That is, the annular fixing block 10 can linearly slide synchronously with the annular connection block 7. Specifically, under the tightening action of the tightening bolts 12, the annular fixing block 10 can be fixed on the roller 4, so as to fix the annular connection block 7 on the roller 4, and then the circular blade 5 can be fixed on the roller 4. Therefore, the staff only needs to loosen or tighten the tightening bolts 12 to control the axial spacing of the plurality of circular blades 5 for adjustment, and the adjustment is convenient;

[0024] The height adjustment assembly includes two receiving cavities 13, which are symmetrically arranged at the bottoms of the two support frames 2. At both ends of the top of the base 1, electric push rods 14 are symmetrically and vertically fixed. It should be noted that an electric push rod is a power-driven device that converts the rotational motion of a motor into the linear reciprocating motion of a push rod. At the top ends of the output shafts of the electric push rods 14, lifting plates 15 are fixed. The surfaces of the lifting plates 15 slide on the inner surfaces of the receiving cavities 13. That is, when the electric push rods 14 operate, they can drive the lifting plates 15 to lift and lower within the receiving cavities 13. At the side ends of the lifting plates 15, second reduction motors 16 are fixed. The output shafts of the second reduction motors 16 pass through the lifting plates 15, and the ends of the material conveying rollers 6 are fixedly connected to the ends of the output shafts of the second reduction motors 16. Specifically, when the second reduction motors 16 operate, they can drive the material conveying rollers 6 to rotate, so as to be used to traction and convey the materials to be cut. Moreover, when the electric push rods 14 operate to drive the lifting plates 15 to lift and lower, they can drive the material conveying rollers 6 to lift and lower, so as to conveniently adjust the height distance between the material conveying rollers 6 and the several circular blades 5, thus facilitating the die-cutting process of the several circular blades 5 on materials of different thicknesses;

[0025] The auxiliary adjustment assembly includes two vertically arranged end plates 17. The bottoms of the two end plates 17 are respectively fixed to the tops of the two support frames 2. On the opposite surfaces of the two end plates 17, a scale plate 18 is fixed. Horizontally, scale lines 19 are arranged on the surface of the scale plate 18. The scale plate 18 and the scale lines 19 are located directly above the several circular blades 5. Specifically, under the marking effect of the scale plate 18 provided with the scale lines 19, it can well assist the staff to accurately adjust the distance between the several circular blades 5.

[0026] It should be noted that this device is electrically connected to an external main controller and 220V mains electricity, and the main controller can be an existing technical device such as a control switch that plays a control role.

[0027] The use process of the present utility model is as follows: The staff can, according to the size to be cut, control whether to fix the circular blades 5 on the rotating rollers 4 by tightening or loosening the tightening bolts 12. Then, with the assistance of the scale plate 18 provided with the scale lines 19, accurately adjust the distance between the several circular blades 5, and by operating the electric push rods 14, control and adjust the height distance between the material conveying rollers 6 and the several circular blades 5, so as to facilitate the die-cutting process of the several circular blades 5 on materials of different thicknesses.

[0028] The above is only a preferred embodiment of the present utility model. Any person skilled in the art can modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model all fall within the scope of protection required by the present utility model.
