[0025] The adjusting assembly 6 further includes a linkage unit 62. The linkage unit 62 includes a sprocket 621. The sprocket 621 is fixedly connected to the arc surface of the threaded rod 614. A chain 622 is installed on the surface of the sprocket 621. An anti-slip knob 623 is fixedly connected to the side surface of the threaded rod 614.

[0026] Specifically, a first rubber pad 617 is fixedly connected to the side surface of the positioning frame 612. The first rubber pad 617 is in contact with the side surface of the linkage block 616. A second rubber pad 619 is fixedly connected to the side surface of the clamping plate 618. The second rubber pad 619 is in contact with the side surface of the linkage block 616. Through the cooperation of the first rubber pad 617 and the second rubber pad 619, the resistance between the clamping plate 618, the positioning frame 612 and the linkage block 616 can be increased in the locked state, thereby improving the stability of the linkage block 616.

[0027] Specifically, the positioning frame 612 is fixedly connected to the side surfaces of the guide rails 613. The number of the guide rails 613 is two. The two guide rails 613 are symmetrically arranged about the adapter plate 611 in the left-right direction.

[0028] In this embodiment: The guide rail 613 can guide the moving direction of the clamping plate 618 to ensure that the clamping plate 618 moves along the same direction.

[0029] Specifically, the number of the threaded rods 614 is two. The two threaded rods 614 are symmetrically arranged about the positioning frame 612 in the left-right direction. The threaded rods 614 penetrate through the side surface of the clamping plate 618. Through the cooperation of the threaded rods 614 and the fastening nuts 6110, the position of the clamping plate 618 can be locked.

[0030] In this embodiment: The limiting slider 615 is cross-shaped.

[0032] Specifically, the sprocket 621 is in contact with the side surface of the positioning frame 612. The number of sprockets 621 is two, and the two sprockets 621 are symmetrically arranged about the positioning frame 612. The chain 622 is engaged with the tooth grooves of the sprockets 621. Through the cooperation of the sprockets 621 and the chain 622, when the unilateral anti-slip knob 623 is rotated, the threaded rods 614 on both sides can be driven to rotate.

[0033] Working principle: When punching a packaging carton, place the cardboard of the packaging carton on the table 2 and ensure that the cardboard is located below the processing area. Operate the cylinder 4 switch on the distribution box 5. The cylinder 4 is powered on and works, and cooperates with the adjusting component 6 to push the punching head 7. The punching head 7 moves downward and punches the surface of the cardboard. When the distance between the punching heads 7 needs to be adjusted, rotate the anti-slip knob 623 counterclockwise. The anti-slip knob 623 rotates the threaded rod 614. The threaded rod 614 rotates the sprocket 621. The sprocket 621 is engaged with the chain 622. The chain 622 rotates and is engaged with the other sprocket 621. The other sprocket 621 drives the other threaded rod 614 to rotate. When the threaded rods 614 on both sides are in a rotating state, the threaded rod 614 is engaged with the fastening nut 6110. The fastening nut 6110 pulls the clamping plate 618 under the action of the threaded rod 614. The clamping plate 618 drives the rubber pad 619 to move outward under the guidance of the guide rail 613. During the movement of the clamping plate 618, the clamping effect on the linkage block 616 is lost. When the linkage block 616 is unlocked, adjust the distance between the two linkage blocks 616. The linkage block 616 drives the punching head 7 to move during the movement. When the punching head 7 moves to the position expected by the operator, stop moving the linkage block 616. Rotate the anti-slip knob 623 clockwise. The anti-slip knob 623 rotates the threaded rods 614 on both sides again in cooperation with the sprockets 621 and the chain 622. The threaded rod 614 is engaged with the fastening nut 6110. The fastening nut 6110 pushes the clamping plate 618. The clamping plate 618 moves under the guidance of the guide rail 613 and pushes the rubber pad 619 to re-clamp and lock the position of the linkage block 616 in cooperation with the positioning frame 612 and the rubber pad 617. Then the adjustment operation of the equipment is completed. By setting the adjusting component 6, the unlocking operation of the equipment can be carried out synchronously, thereby reducing the problem that the adjustment operation of the equipment is inconvenient due to the need to perform the unlocking operation separately, and further improving the convenience of the equipment adjustment operation.
