[0027] Embodiment:

[0028] When the die cutting knife body 2 is installed and fixed, first, the mounting plate 17 is inserted into the clamping groove through one side of the clamping groove, until the limiting plate 23 on the mounting plate 17 abuts against the outer wall of the U-shaped block 10, at this time, the through hole, the positioning hole 21 and the positioning groove 22 are on the same axis;

[0029] Next, rotate the knob to drive the lead screw 13 to rotate. With the threaded engagement between the movable plate 14 and the lead screw 13, and the sliding engagement between the movable plate 14 and the guide rod, adjust the two movable plates 14 to stably approach each other. Under the hinge action at both ends of the connecting arm 16, and with the sliding engagement between the lifting plate 15 and the fixed rod 19, the lifting plate 15 is pressed towards the slot and the spring 20 is compressed until the positioning rod 18 passes through the through hole and the positioning hole 21 on the mounting plate 17 and is inserted into the positioning groove 22, fixing the mounting plate 17 in the slot. This achieves the installation and fixation of the die-cutting blade body 2 without the need for multiple screws.

[0030] When performing die-cutting, the material to be die-cut can be placed on the placement plate 25, and the hydraulic rod 11 can be activated to push the U-shaped block 10 downward, thereby driving the die-cutting blade body 2 downward to perform the die-cutting operation.

[0031] When the die-cutting machine needs to be inspected and maintained during operation, the servo motor 27 is started first. The servo motor 27 drives the rotating rod 26 to rotate, which in turn drives the first bevel gear 6 to rotate. Under the meshing action of the first bevel gear 6 and the second bevel gear 7, combined with the rotation of the support shaft 5, the support shaft 5 is driven to rotate. As the support shaft 5 rotates, the support plates 8 on both sides are rotated synchronously. With the cooperation of the horizontal plate 9 and the hydraulic rod 11, the U-shaped block 10 is rotated around the support shaft 5, which in turn drives the die-cutting machine body 2 to rotate synchronously until the die-cutting machine body 2 is rotated to a forward or upward state. This makes it convenient for the staff to inspect and maintain the die-cutting machine body 2, solving the drawback that the existing die-cutting machine's die needs to be installed below the die-cutting mechanism, which is inconvenient for die inspection and maintenance.

[0032] The servo motor 27 is controlled by an external control mechanism to rotate 90° or 180°, thereby adjusting the die-cutting blade body 2 to face forward or upward.

[0033] When the die cutting knife body 2 needs to be disassembled and replaced after maintenance, at this time, the knob is reversely rotated, the lead screw 13 is reversely rotated, the two movable plates 14 are stably adjusted away from each other, under the elastic action of the spring 20, combined with the hinged action of the connecting arms 16 at both ends, the lifting plate 15 is extruded upwards along the direction of the fixed rod 19, the positioning rod 18 is synchronously upwards, until the positioning rod 18 is separated from the positioning hole 21 on the mounting plate 17, under the action of the limiting plate 23, the mounting plate 17 is pulled out from the clamping groove, the die cutting knife body 2 is quickly disassembled, and the die cutting knife body 2 to be replaced is installed on the U-shaped block 10 according to the above steps, so that the knife die of the existing die cutting machine is generally fixed on the knife holder of the die cutting machine through a plurality of screws, when the knife die is installed, fixed and disassembled and replaced, a plurality of screws need to be tightened and loosened one by one, the operation is more troublesome, the labor intensity of workers is increased, the knife die cannot be quickly installed and disassembled, and the defects of affecting the use of the die cutting machine are solved.

[0034] It should be further pointed out that the mounting structure, connection mode or setting mode of each component in the utility model are common mechanical modes, as long as the beneficial effects can be achieved, and the hydraulic rod 11, the die cutting knife body 2 and the servo motor 27 in the utility model are purchased on the market, and the workers in the field can install and use according to requirements;

[0035] The die cutting knife body 2 is driven to move by the hydraulic rod 11 to realize die cutting of materials, which is a common technical means in the field, and the specific operation method will not be repeated here.

[0036] The baffle effectively limits the supporting plate 8, ensures that the supporting plate 8 can stay in a vertical state, and further ensures that the die cutting knife body 2 can stay in a state of facing the placing plate 25, so as to facilitate the implementation of die cutting.
