The change requires disassembling the screws one by one, which is cumbersome and causes the production line to be shut down for a long time, greatly reducing the efficiency of carton processing. Utility Model Content

[0004] The main objective of this invention is to provide a die-cutting machine for cardboard packaging, which can effectively solve the problem in the background art where workers need to change the die when producing cardboard boxes of different specifications. The change requires disassembling the screws one by one, which is cumbersome and causes the production line to be shut down for a long time, greatly reducing the efficiency of cardboard box processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A die-cutting machine for carton packaging includes two supports, a transmission belt between the two supports, a frame fixedly mounted on the upper surface of the two supports, a rotating drum rotatably mounted between the two sides of the inner wall of the frame via bearings, a plurality of sliding columns slidably arranged through the body of the rotating drum, a rotating plate fixedly mounted at one end of adjacent sliding columns, a die provided on one side of each rotating plate, a limiting plate fixedly mounted at the other end of adjacent sliding columns, and a spring sleeved on the side of each sliding column near the corresponding limiting plate;

[0007] A drive assembly for driving the rotating drum is provided on one side of the frame;

[0008] The upper surface of the frame is provided with a pushing component for pushing the limiting plate.

[0009] Preferably, the drive assembly includes a right-angle frame, which is fixedly installed on one side of the frame. A motor is fixedly installed on one side of the inner wall of the right-angle frame. A gear is sleeved on the output shaft of the motor, and an internal gear ring is sleeved on the inner wall of the rotating drum. The gear meshes with the internal gear ring.

[0010] Preferably, the pushing assembly includes two uprights, which are respectively fixedly installed on both sides of the upper surface of the frame. A top plate is fixedly installed on the upper end of the two uprights. A cylinder is fixedly installed on the upper surface of the top plate. The output end of the cylinder passes through the top plate and is fixedly installed with a lifting frame. The lifting frame is slidably arranged on one side of the two uprights. A pressure rod is fixedly installed between the two sides of the inner wall of the lifting frame.

[0011] Preferably, each of the rotating plates has a limit hole through one side surface, and each of the die-cutting molds has a number of limit posts fixedly installed on one side, with each limit post interlocking with the corresponding limit hole.

[0012] Preferably, each of the rotating plates has a groove on one side surface, two sliders are slidably disposed in each groove, and a right-angle plate is fixedly installed on one side of each slider;

[0013] Each of the limiting holes has a through-hole for a connecting groove on its inner wall surface, and each of the limiting posts has a slot on its body surface. Each right-angle plate has two positioning posts fixedly installed on the side near the corresponding slot, and each positioning post is inserted into and cooperates with the corresponding slot.

[0014] A bidirectional lead screw is rotatably installed between the two sides of the inner wall of each slide groove. A first bevel gear is sleeved in the middle of the body of each bidirectional lead screw. A support block is fixedly installed on one side of each rotating plate.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] like Figures 1-8 As shown, a die-cutting machine for carton packaging includes two supports 1, a transmission belt 2 between the two supports 1, a frame 101 fixedly installed on the upper surface of the two supports 1, a rotating drum 4 rotatably installed between the two sides of the inner wall of the frame 101 via bearings 3, a plurality of sliding columns 5 are slidably arranged through the body of the rotating drum 4, a rotating plate 6 is fixedly installed at one end of adjacent sliding columns 5, a die 7 is provided on one side of each rotating plate 6, a limiting plate 8 is fixedly installed at the other end of adjacent sliding columns 5, and a spring 801 is sleeved on the side of each sliding column 5 near the corresponding limiting plate 8;

[0030] A drive assembly 9 for driving the rotating drum 4 is provided on one side of the frame 101;

[0031] The upper surface of the frame 101 is provided with a pushing assembly 10 for pushing the limit plate 8.

[0032] The drive assembly 9 includes a right-angle frame 901, which is fixedly installed on one side of the frame 101. A motor 902 is fixedly installed on one side of the inner wall of the right-angle frame 901. A gear 903 is sleeved on the output shaft of the motor 902. An internal gear ring 904 is sleeved on the inner wall of the rotating drum 4. The gear 903 meshes with the internal gear ring 904.

[0033] The pushing assembly 10 includes two uprights 1001, which are respectively fixedly installed on both sides of the upper surface of the frame 101. A top plate 1002 is fixedly installed on the upper end of the two uprights 1001. A cylinder 1003 is fixedly installed on the upper surface of the top plate 1002. The output end of the cylinder 1003 passes through the top plate 1002 and is fixedly installed with a lifting frame 1004. The lifting frame 1004 is slidably disposed on one side of the body of the two uprights 1001. A pressure rod 1005 is fixedly installed between the two sides of the inner wall of the lifting frame 1004.

[0034] The operator starts the transmission belt 2 to transport the cardboard. After the cardboard moves under the die 7, the operator starts the motor 902, which drives the gear 903 to rotate. The gear 903 then drives the rotating drum 4 to rotate through the internal gear ring 904, causing the target die 7 to rotate to the working position. Then, the operator starts the cylinder 1003, which drives the lifting frame 1004 to descend. This allows the lifting frame 1004 to push the limiting plate 8, which in turn pushes the die 7. This allows the die 7 to die-cut the cardboard, significantly shortening the die 7 replacement time, saving time and effort, and avoiding the situation where long downtime for die 7 replacement leads to a significant reduction in processing efficiency.

[0035] In another embodiment of this utility model, a limiting hole 11 is provided through one side surface of each rotating plate 6, and a plurality of limiting posts 12 are fixedly installed on one side of each die 7, with each limiting post 12 interlocking with the corresponding limiting hole 11.

[0036] Each rotating plate 6 has a groove 13 on one side surface, and two sliders 14 are slidably arranged in each groove 13. A right-angle plate 15 is fixedly installed on one side of each slider 14.

[0037] Each limiting hole 11 has a connecting groove 16 through the inner wall surface, each limiting post 12 has a slot 17 on the post body surface, and each right angle plate 15 has two positioning posts 18 fixedly installed on the side near the corresponding slot 17, and each positioning post 18 is inserted and engaged with the corresponding slot 17.

[0038] A bidirectional lead screw 19 is rotatably installed between the two sides of the inner wall of each slide 13. A first bevel gear 20 is sleeved in the middle of the shaft of each bidirectional lead screw 19. A support block 21 is fixedly installed on one side of each rotating plate 6. A horizontal shaft 22 is rotatably installed through one side of each support block 21. A second bevel gear 23 is sleeved on one end of each horizontal shaft 22. The second bevel gear 23 meshes with the first bevel gear 20. A rotating block 24 is fixedly installed on the other end of each horizontal shaft 22.

[0039] Adjacent sliders 14 are threaded onto both sides of the corresponding bidirectional lead screw 19.

[0040] A through groove 25 is provided on one side of the inner wall of the frame 101.

[0041] The operator can rotate the rotating block 24 through the through slot 25, causing it to drive the horizontal shaft 22 to rotate. The horizontal shaft 22 then drives the second bevel gear 23 to rotate. Under the meshing action of the second bevel gear 23 and the first bevel gear 20, the double-acting screw 19 drives the adjacent right-angle plate 15 to move relative to each other through the screw thread, causing the adjacent positioning pin 18 to disengage from the corresponding slot 17. Then, the operator pulls the die 7, causing the limiting pin 12 to disengage from the corresponding limiting hole 11, making it convenient for the operator to replace the die 7. After installing different die 7s, the operator rotates the rotating block 24 in the opposite direction, causing the limiting pin 12 to re-insert into the corresponding slot 17, thereby quickly installing the new die 7. This allows the operator to quickly replace the die 7 on one side of the rotating plate 6 according to work requirements.

[0042] The working principle of a die-cutting machine for cardboard packaging:

[0043] In operation, the operator starts the transmission belt 2 to transport the cardboard. After the cardboard moves under the die 7, the operator starts the motor 902, which drives the gear 903 to rotate. The gear 903 then drives the rotating drum 4 to rotate through the internal gear ring 904, causing the target die 7 to rotate to the working position. Subsequently, the operator starts the cylinder 1003, which drives the lifting frame 1004 to descend. This allows the lifting frame 1004 to push the limiting plate 8, which in turn pushes the die 7, enabling the die 7 to die-cut the cardboard. This significantly shortens the die 7 replacement time, saving time and effort, and avoiding the situation where long downtime for die 7 replacement leads to a significant reduction in processing efficiency.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
