Abstract
Description
Technical Field
[0001] This utility model relates to a carton die-cutting device, specifically a die-cutting device for paper packaging boxes, belonging to the field of die-cutting machine technology. Background Technology
[0002] In short, it's a machine used for die-cutting cardboard in the carton forming process. It generally comes in two types: flatbed die-cutting and rotary die-cutting. As packaging is increasingly used to attract consumers beyond just transportation, its market share is growing. Both flatbed and rotary die-cutting machines require peripheral equipment such as pre-feeders, cardboard stacking and separating devices, stackers, and cardboard bundle handling devices to ensure maximum production efficiency in the die-cutting process.
[0003] A search revealed Chinese Patent Publication No. CN214136376U, which discloses a packaging box die-cutting device. This device relates to the technical field of flatbed die-cutting machines for paper products. The clamping mechanism is connected to the drive mechanism and includes an upper clamping plate, a lower clamping plate, and a sliding reset assembly. The upper and lower clamping plates are slidably connected to the clamping mechanism via the sliding reset assembly. Control components are provided on the side plates to control the relative movement of the upper and lower clamping plates. This application enables the cardboard to automatically move onto the cutting mechanism for die-cutting.
[0004] While the above solutions can automatically move to the cutting mechanism for die-cutting, the die-cutting device in the aforementioned patent has difficulty cleaning impurities attached to the surface of the carton. These impurities are pressed into the cardboard fibers during die-cutting, resulting in uneven pressure distribution, rough edges, or uneven cuts, which affects the integrity of the precision die-cut pattern. Therefore, we provide a die-cutting device for paper packaging boxes to solve the above problems. Utility Model Content

The telescopic end of the second electric telescopic rod 11 is slidably connected to the inner wall of the storage box 8. The telescopic end of the second electric telescopic rod 11 passes through the storage box 8 and is installed inside the storage box 8. When the second electric telescopic rod 11 is telescopic, the storage box 8 can prevent the second electric telescopic rod 11 from tilting, thus playing a fixing role. The telescopic end of the second electric telescopic rod 11 is fixedly connected to one side of the push plate 12. The fixing frame 10 is installed on the storage box 8 and can fix the second electric telescopic rod 11, thus playing a fixing role. The push plate 12 is installed on the second electric telescopic rod 11. The second electric telescopic rod 11 can push the push plate 12 to slide inside the storage box 8, thereby pushing the cardboard boxes stored in the storage box 8 out, effectively improving the feeding speed.
[0021] Example 2: The storage box 8 has a second slide groove 9 on its inner side, and a push plate 12 is slidably connected to the inner side of the second slide groove 9. The storage box 8 is installed on the base 6 and serves to fix it. The cardboard boxes that need to be die-cut are placed in the storage box 8 for storage, which can improve the feeding speed. The second slide groove 9 in the storage box 8 can guide the push plate 12 and prevent the push plate 12 from tilting when pushing the cardboard box to one end, thus serving a guiding function.
[0022] A die-cutting machine 7 is fixedly connected to the upper surface of the base 6. Both the support frame 4 and the die-cutting machine 7 are installed on the base 6. The die-cutting machine 7 can perform die-cutting on the carton and also serves to fix it. The inner side of the support frame 4 is provided with a first sliding groove 5. The inner side of the first sliding groove 5 is slidably connected to one end of the lifting plate 1. The first electric telescopic rod 3 is installed between the lifting plate 1 and the support frame 4.

The first sliding groove 5 provided in the support frame 4 can guide the lifting plate 1 and prevent the lifting plate 1 from tilting when it is raised and lowered, thus serving a guiding function.
[0023] Example 3: A cleaning mechanism 2 is provided on the lower surface of the lifting plate 1. The cleaning mechanism 2 includes a first motor 201 fixedly connected to the upper surface of the lifting plate 1. The output shaft of the first motor 201 is rotatably connected to the inner wall of the lifting plate 1. The output shaft of the first motor 201 passes through the lifting plate 1. The first motor 201 is installed on the lifting plate 1. The lifting plate 1 can fix the first motor 201 in operation, thus playing a fixing role.
[0024] Please see Figure 2 and Figure 3 The output shaft of the first motor 201 is fixedly connected to a rotating disk 202. A first rotating shaft 203 is rotatably connected to the lower surface of the rotating disk 202. A connecting rod 204 is fixedly connected to the lower end of the first rotating shaft 203.

The inner wall of the limit block 209 is flush with the outer surface of the sliding plate 206. The surface is slidably connected. The first motor 201 drives the rotating disk 202 to rotate. The rotating disk 202 drives the first rotating shaft 203 mounted on the rotating disk 202 to rotate. The first rotating shaft 203 drives the connecting rod 204 and the second rotating shaft 205 to rotate. The second rotating shaft 205 is installed in the groove of the sliding plate 206. Under the action of the rotating disk 202, the second rotating shaft 205 can slide back and forth in the sliding plate 206, thereby driving the sliding plate 206 to slide left and right. This drives the cleaning brush 208 to clean the surface of the carton, thereby improving the cleaning effect.
[0025] The first motor 201, the first electric telescopic rod 3, the die-cutting machine 7, the second electric telescopic rod 11, and the second motor 14 in this application are all common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.
[0026] Working principle: The first motor 201 is started, which drives the rotating disk 202 to rotate. The rotating disk 202 drives the connecting rod 204 to make circular motion through the first rotating shaft 203. The second rotating shaft 205 at the end of the connecting rod 204 slides in the groove of the sliding plate 206, converting the circular motion into linear reciprocating motion. The sliding plate 206 moves horizontally and reciprocally under the constraint of the limit block 209, which drives the connecting plate 207 and the cleaning brush 208 to swing left and right. The swinging action of the cleaning brush 208 cleans the impurities on the surface of the carton, ensuring that the carton is clean before die-cutting. The carton is stacked in the storage box 8. The second electric telescopic rod 11 pushes the push plate 12 to push the carton to the conveyor belt 16. The second motor 14 drives the third rotating shaft 15, which drives the conveyor belt 16 to transport the carton to the die-cutting station. The first electric telescopic rod 3 adjusts the height of the lifting plate 1 so that the cleaning brush 208 can adapt to cartons of different thicknesses. The cleaned carton enters the die-cutting machine 7 to complete precise die-cutting, realizing the cleaning of impurities attached to the surface of the carton.
