[0002] Carton packaging refers to the packaging of products in paper boxes to protect them, facilitate storage and transportation, and promote sales during the circulation process. Carton packaging is the most widely used packaging method. In the production process, existing cartons are made of cardboard through die-cutting, punching, and gluing. When holes are made on the surface of the carton, special hole-making machines are generally used to complete the process.

[0003] Traditional punching machines for packaging cartons still have certain shortcomings during use: some small semi-automatic punching machines require workers to manually move the cardboard under the pressing block during use, but due to the lack of good positioning function, the positions of the holes opened on different cardboards are different, and since the opening positions on cardboards of different specifications are different, the traditional positioning mechanism is not convenient for rapid adjustment. Secondly, some cartons will have rounded rectangular holes on both sides as handle grooves, and some will have a set of symmetrical circular holes on them. The current small semi-automatic punching machines cannot achieve rapid switching of different hole opening components, and the spacing between the circular holes is not convenient to adjust.

[0004] Therefore, it is necessary to provide a new packaging carton punching device to solve the above technical problems. Utility Model Content

[0039] like Figure 1 As shown, the surfaces of the two sliding members 15 are both provided with scales 13 , and an indicating needle 14 is provided at a position on one side of the scales 13 .

[0040] During the use of some small semi-automatic punching machines, workers need to manually move the cardboard to the bottom of the pressure block to complete the operation. However, due to the lack of a good positioning function, the positions of the holes opened on different cardboards are different. In addition, since the opening positions on cardboards of different specifications are different, it is not convenient for traditional positioning mechanisms to make quick adjustments. Two sets of positioning components 9 are provided in the device to limit the position of the cardboard. At the same time, a transmission rod 19 for adjusting the position of the limiter 12 is provided on one side of the worker's body.

[0045] The working principle of a packaging carton punching device provided by the utility model is as follows:

[0046] Step 1: Some cartons will have rounded rectangular holes on both sides as handle grooves, and some will have a group of symmetrical round holes on them. The current small semi-automatic punching machine cannot realize the rapid switching of different hole-opening components, and the spacing between the round holes is not convenient to adjust. In this device, when the user moves the rack 25 on one side, the rack 25 on the other side will rise, thereby realizing the switching of the first pressing block 23 and the second pressing block 29. After the switching is completed, the limit frame 27 can be plugged into the corresponding socket 28 on the frame using a latch. At the same time, the first pressing block 23 is slidably connected to the first mounting member 6. When the user needs to adjust the spacing between the two round holes on the cardboard, he only needs to loosen the nut and move the position. The overall structure is very convenient to operate, which is conducive to workers' use and switching;

[0047] The second step: During the use of some small semi-automatic punching machines, workers are required to manually move the cardboard to the bottom of the pressing block to complete the process. However, due to the lack of a good positioning function, the positions of the holes opened on different cardboards are different. In addition, since the opening positions on cardboards of different specifications are different, it is not convenient for traditional positioning mechanisms to make quick adjustments. Two sets of positioning components 9 are set in the device to limit the position of the cardboard. At the same time, the transmission rod 19 for adjusting the position of the limiter 12 is set on the side of the worker's body. When the position of the limiter plate needs to be adjusted, it is only necessary to rotate the corresponding transmission rod 19 and control the adjustment distance according to the cooperation of the indicator needle 14 and the scale 13. The structure is very convenient to operate and can accurately position the cardboard to avoid mistakes made by workers.
