[0038] It should be noted that, by cooperating with the first drive motor 12 and the bidirectional screw rod 13, by starting the first drive motor 12, the output shaft of the first drive motor 12 rotates to drive the bidirectional screw rod 13 to rotate, and when the bidirectional screw rod 13 rotates, it can simultaneously drive the first movable plate 10 and the second movable plate 11 to move, so that the distance between the first movable plate 10 and the second movable plate 11 can be adjusted, so that the staff can enter the equipment to install and disassemble the die-cutting plate 403.

[0039] In an optional embodiment: a conveying mechanism 14 is provided on the first movable plate 10 and the second movable plate 11, and the conveying mechanism 14 includes a driven wheel 1401, a conveyor belt 1402, a driving wheel 1403, a second drive motor 1404, a connecting rod 1405 and a positioning block 1406, and the driven wheel 1401 and the driving wheel 1403 are both movably installed on the inner side of the first movable plate 10 and the second movable plate 11, and the conveyor belt 1402 is arranged on the lifting plate 401 and the driving wheel 1403.

[0041] In an optional embodiment: the positioning block 1406 is fixedly connected to the connecting rod 1405 , a positioning groove 1407 is defined in the driving wheel 1403 , and the positioning block 1406 is inserted into the positioning groove 1407 .

[0042] It should be noted that, through the cooperation of the positioning block 1406, the connecting rod 1405 and the positioning groove 1407, when the distance between the first movable plate 10 and the second movable plate 11 is adjusted, the driving wheel 1403 can slide on the positioning block 1406 and the connecting rod 1405 through the positioning groove 1407;

[0043] In addition, by cooperating with the positioning slot 1407, when the second driving motor 1404 drives the connecting rod 1405 to rotate, the positioning block 1406 cooperates with the positioning slot 1407 to drive the driving wheel 1403 to rotate, and the driving wheel 1403 cooperates with the driven wheel 1401 and the conveyor belt 1402 to transport the cardboard.

[0044] In an optional embodiment: a support seat 15 is fixedly installed on the top of the base plate 1, a pushing cylinder 16 is fixedly installed on the inner top of the support seat 15, a push plate 17 is fixedly installed on the telescopic end of the push cylinder 16, a first pearl cotton foam board 18 is fixedly installed on the top of the push plate 17, and the first pearl cotton foam board 18 is arranged directly below the die-cutting plate 403.

[0045] It should be noted that, by pushing the cylinder 16 and the push plate 17, the first pearl cotton foam board 18 can contact the bottom of the cardboard. When the die-cutting plate 403 and the die-cutting knife 404 die-cut the cardboard, the push plate 17 can support the cardboard, and the first pearl cotton foam board 18 can prevent the die-cutting knife 404 from contacting with the push plate 17 and being worn.

[0046] In an optional embodiment: a second pearl cotton foam board 19 is fixedly installed on the top of the push plate 17, and the second pearl cotton foam board 19 is arranged directly below the mounting plate 406, and blanking holes 20 are opened on the support seat 15, the push plate 17 and the second pearl cotton foam board 19.

[0047] It should be noted that, through the setting of the second pearl cotton foam board 19, while the cardboard is die-cut by the die-cutting knife 404, the pressing block 407 can press down the die-cut cardboard, so that the packaging box obtained by die-cutting can be pressed up and down and separated from the cardboard, so that the packaging box can fall on the top of the bottom plate 1 through the blanking hole 20 for collection.

[0048] When in use, first place the cardboard on the conveyor belt 1402, start the second drive motor 1404, and the output shaft of the second drive motor 1404 rotates to drive the connecting rod 1405 to rotate, and the connecting rod 1405 rotates to drive the positioning block 1406 to rotate, and the positioning block 1406 rotates to cooperate with the positioning groove 1407 to drive the driving wheel 1403 to rotate, and the driving wheel 1403, the driven wheel 1401 and the conveyor belt 1402 cooperate to transport the cardboard;

[0049] After the cardboard is conveyed to the top of the first pearl cotton foam board 18, the second drive motor 1404 stops working, the push cylinder 16 is started, and the telescopic rod of the push cylinder 16 pushes the push plate 17, so that the push plate 17 drives the first pearl cotton foam board 18 to move. When the telescopic rod of the push cylinder 16 moves to the maximum stroke, the first pearl cotton foam board 18 contacts the bottom of the cardboard, the hydraulic cylinder 3 is started, and the telescopic rod of the hydraulic cylinder 3 pushes the lifting plate 401, so that when the lifting plate 401 moves downward, it drives the die-cutting knife 404 to approach the cardboard, and the cardboard is die-cut by the die-cutting knife 404. After the cardboard is die-cut, the telescopic rod of the hydraulic cylinder 3 retracts to drive the die-cutting knife 404 to return to its original position, and the telescopic rod of the push cylinder 16 retracts to drive the first pearl cotton foam board 18 to return to its original position, and the second drive motor 1404 is started, so that the cardboard can continue to be conveyed;

[0050] When the die-cut cardboard moves to the top of the second pearl cotton foam board 19, and the new cardboard moves to the top of the first pearl cotton foam board 18, the second drive motor 1404 stops working, the push cylinder 16 is started, and the telescopic rod of the push cylinder 16 pushes the push plate 17, so that the push plate 17 drives the first pearl cotton foam board 18 and the second pearl cotton foam board 19 close to the cardboard, and the hydraulic cylinder 3 is started, and the telescopic rod of the hydraulic cylinder 3 pushes the lifting plate 401, so that when the lifting plate 401 moves downward, the die-cutting knife 404 continues to die-cut the cardboard, and the pressing block 407 can press down the die-cut cardboard, so that the packaging box obtained by die-cutting can be separated from the cardboard by pressing up and down, so that the packaging box can fall on the top of the bottom plate 1 through the blanking hole 20 for collection;

[0051] When the die-cutting plate 403 needs to be disassembled and replaced, the screw 6 is rotated so that the screw 6 can drive the stopper 7 to move upward. When the stopper 7 moves upward and away from the mounting block 405, the force of the stopper 7 pressing against the mounting block 405 disappears. The die-cutting plate 403 is pushed so that the die-cutting plate 403 moves in the mounting seat 402 through the plug-in block 408. At this time, the die-cutting plate 403 can be disassembled and replaced.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
