DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present utility model with reference to embodiments.

[0023] Please refer to Figures 1-3, the present utility model provides a carton production hole - opening device, including: a bottom plate 1 and a cover plate 2. At both ends of the opposite sides of the bottom plate 1 and the cover plate 2, connecting frames 3 are fixedly connected. On the opposite sides of the symmetric connecting frames 3, first sliding grooves 301 are provided. Threaded shafts 4 are slidably connected to the first sliding grooves 301. At the upper ends of the symmetric threaded shafts 4, a first connecting belt 8 is meshed. The middle of the first connecting belt 8 is meshed with the outer surface of the driving shaft at the output end of the first servo - motor 10. And on the outer surfaces of the lower ends of the symmetric threaded shafts 4, first sliding plates 5 are threadedly connected.

And on the outer surfaces of the upper ends of the symmetric threaded shafts 4, second sliding plates 6 are threadedly connected. An opening cutter 12 is installed at the lower end of the second sliding plate 6.

[0024] Further, as Figure 1 shown, it is specifically noted that guide columns 7 are fixedly connected to the four corners of the opposite surfaces of the bottom plate 1 and the cover plate 2. Through the guide columns 7, the position and movement trajectory of the first sliding plate 5 can be further restricted, increasing the stability during the hole - opening of the carton production.

[0025] Further, as Figure 1 shown, it is specifically noted that on the outer surface of the symmetric threaded shafts 4, baffle plates 401 are provided on both the upper and lower sides of the first connecting belt 8. Through the symmetric baffle plates 401, the position and movement trajectory of the first connecting belt 8 are restricted.

[0026] Further, as Figure 1 shown, it is specifically noted that in the middle of the upper end of the cover plate 2, a fixing frame 9 is provided. The upper end of the fixing frame 9 is fixedly connected to the lower end of the first servo - motor 10. Through the fixing frame 9, it is convenient for the driving shaft at the output end of the first servo - motor 10 to drive the meshed first connecting belt 8 to rotate.

[0027] The working process of this solution is as follows: First, the driving shaft meshed with the output end of the first servo - motor 10 drives the first connecting belt 8 to rotate. The first connecting belt 8 drives the symmetric threaded shafts 4 to rotate. Because the positions and movement trajectories of the first sliding plate 5 and the second sliding plate 6 are restricted, the first sliding plate 5 and the second sliding plate 6 will move relatively as the symmetric threaded shafts 4 rotate. That is, the carton and the opening cutter 12 can be relatively moved to a suitable position. Then, according to the position where the carton needs to be punched, the output end of the second servo - motor 607 drives the rotating sliding shaft 606 to rotate, that is, drives the sliding frame 604 to move left and right on the second sliding plate 6 to a suitable position. At the same time, cooperate with the front - and - back movement of the limiting plate 1101 of the limiting device 11. Then rotate the fixed shaft 1104 to fix the limiting plate 1101 on the upper surface of the first sliding plate 5. Finally, the punching operation can be accurately performed on any position of the carton.

[0028] According to the above working process, it can be seen that: through the guide post 7, the position and movement trajectory of the first sliding plate 5 can be further restricted, increasing the stability during the hole opening in the production of this carton. Through the symmetric baffle 401, the position and movement trajectory of the first connecting belt 8 are restricted.

Through the first sliding plate 5, that is, the driving shaft meshed and connected to the output end of the first servo motor 10 drives the first connecting belt 8 to rotate. The first connecting belt 8 drives the symmetric threaded shaft 4 to rotate. Because the positions and movement trajectories of the first sliding plate 5 and the second sliding plate 6 are restricted, the first sliding plate 5 and the second sliding plate 6 will move relatively as the symmetric threaded shaft 4 rotates, that is, the carton and the hole opener 12 can be relatively moved to a suitable position, so that the carton and the hole opener 12 can be relatively moved, thereby making the hole opening of the carton more convenient, and further increasing the practicability of the carton production hole opening equipment.

Through the limiting device 11, that is, according to the position where the carton needs to be punched, the limiting plate 1101 of the limiting device 11 is moved back and forth in cooperation, and then the fixed shaft 1104 is rotated to fix the limiting plate 1101 on the upper surface of the first sliding plate 5, and finally the punching operation can be accurately performed at any position of the carton, thereby further increasing the practicability of the carton production hole opening equipment.

The sliding shaft 606 penetrates and is slidably connected to the other end of the sliding frame 604 and is meshed and connected to the output end of a second servo motor 607. A second scale 605 is provided at the lower side of the front end of the second sliding plate 6.
