The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0031] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0032] A plastic packaging box punching device, as Figure 1 - Figure 5As shown in the figure, it includes a plastic punching machine 1 and a punching punch 2. A punching box 3 is slidably installed in the plastic punching machine 1, and a first coupling shaft 4 is fixedly installed in the punching box 3. A first connecting rod 5 and a second connecting rod 6 are rotatably installed on the outer wall of the first coupling shaft 4. The end of the first connecting rod 5 is rotatably installed with a second coupling shaft 7, and the end of the second connecting rod 6 is rotatably installed with a telescopic rod base 9. A push rod 8 is fixedly installed on the outer wall of the second coupling shaft 7. A telescopic rod 15 is slidably installed in the telescopic rod base 9, and the telescopic rod 15 is fixedly connected to the outer wall of the limiting plate 11. A collecting component for collecting plastic sheets is fixedly installed on the outer wall of the plastic punching machine 1. A driving component for the user to reset the telescopic rod base 9 is installed on the outer wall of the telescopic rod base 9. The punching box 3 starts to slide on the outer wall of the plastic punching machine 1. Under the restriction of the collecting plate 12, the spring 10 is in contact with the outer wall of the collecting plate 12. At this time, the telescopic rod 15 in the telescopic rod base 9 starts to slide in the telescopic rod base 9. When the bottom horizontal plane of the plastic punching machine 1 coincides with the top horizontal plane of the spring 10, the plastic packaging box is cut by the punching punch 2. At this time, the telescopic rod base 9 on the outer wall of the spring 10 drives the first connecting rod 5 and the second connecting rod 6 to rotate in the punching punch 2 under the restriction of the collecting plate 12. Under the restriction of the first coupling shaft 4, the second connecting rod 6 rotatably connected to the telescopic rod base 9 starts to rotate on the outer wall of the first coupling shaft 4. At the same time, the first connecting rod 5 slidably connected to the second connecting rod 6 also rotates on the outer wall of the first coupling shaft 4, thereby driving the second coupling shaft 7 to slide in the punching box 3, so that the push rod 8 slides in the punching box 3. As the plastic punching machine 1 is further pressed, the bottom horizontal plane of the push rod 8 starts to contact the plastic sheet. Then, the plastic sheet cut by the punching punch 2 is pushed by the push rod 8 and smoothly enters the collecting box 13 through the chute provided in the spring 10 due to the restriction of the collecting plate 12.

[0033] Please refer to Figure 2 and Figure 3 , two groups of the first coupling shafts 4 are symmetrically arranged in the punching box 3, and the first connecting rod 5 and the second connecting rod 6 are slidably connected. Moreover, the first connecting rod 5 and the second connecting rod 6 are located on the same straight line, and the first coupling shaft 4 is located at the central position of the straight line of the first connecting rod 5 and the second connecting rod 6. Under the restriction of the punching box 3, the first connecting rod 5 and the second connecting rod 6 can rotate smoothly. At the same time, the first connecting rod 5 and the second connecting rod 6 start to slide on the outer wall of the first coupling shaft 4 to ensure that the first connecting rod 5 and the second connecting rod 6 can rotate better in the punching punch 2.

[0034] Please refer to Figure 2 and 3 the figure. A chute corresponding to the push rod 8 is opened in the punching punch 2, and the push rod 8 is located inside the plastic punching machine 1. By the rotation of the two groups of the first connecting rod 5 and the second connecting rod 6, the second coupling shaft 7 is driven to slide up and down, and at the same time, the push rod 8 is driven to slide up and down to ensure that the two groups of the first connecting rod 5 and the second connecting rod 6 rotate under the drive of the telescopic rod base 9 and at the same time drive the second connecting rod 6 to start to slide in the punching box 3.

[0035] Please refer to Figure 2 and Figure 4 , the telescopic rod base 9 is slidably connected to the stamping box 3, and a spring for resetting the telescopic rod 15 is installed inside the telescopic rod base 9. A chute opposite to the plastic punching machine 1 is opened in the limiting plate 11. Under the limitation of the collecting plate 12, the limiting plate 11 starts to drive the telescopic rod 15 to slide inside the telescopic rod base 9. As the limiting plate 11 continues to move, finally the limiting plate 11 abuts against the outer wall of the limiting block 14 on the outer wall of the telescopic rod base 9, and then pushes the telescopic rod base 9 to start sliding inside the stamping box 3, ensuring that under the setting of the chute in the spring 10, the punching punch 2 can better punch the plastic packaging box, and at the same time, the telescopic rod 15 can be smoothly reset under the action of the spring inside the telescopic rod base 9.

[0036] Please refer to Figure 1 and Figure 5 , the collecting assembly includes a collecting plate 12 and a collecting box 13. The collecting plate 12 is fixedly connected to the outer wall of the plastic punching machine 1, and the collecting box 13 is slidably connected to the collecting plate 12. The user can clean the collecting box 13 by taking out the collecting box 13, ensuring that the plastic sheets entering the collecting box 13 can be smoothly cleaned.

[0037] Please refer to Figure 1 and Figure 5 , a chute for collecting plastic sheets is opened in the collecting plate 12, and the collecting box 13 is located on the outer wall away from the stamping box 3. The plastic sheets cut by the punch pass through the chute in the limiting plate 11 under the push of the push rod 8 and enter the collecting box 13, ensuring that the collecting box 13 can smoothly collect the plastic sheets.

[0038] Please refer to Figure 4 , the driving assembly includes a limiting block 14 and a spring 10. A spring 10 is sleeved on the outer wall of the telescopic rod base 9, and a limiting block 14 is fixedly installed at the end of the telescopic rod base 9. The spring 10 is located between the stamping box 3 and the limiting block 14. Under the action of the self-stress of the spring 10, the limiting block 14 is pushed to drive the telescopic rod base 9 to start resetting through the limitation of the stamping box 3, ensuring that the telescopic rod base 9 can be smoothly reset through the setting of the spring 10.

[0039] Please refer to Figures 2 - 4 , the chute opened in the collecting plate 12 is larger than the chute opened in the limiting plate 11. The plastic sheets cut by the punching punch 2 smoothly pass through the chute in the limiting plate 11 and enter the chute in the collecting plate 12 under the push of the push rod 8, ensuring that the collecting box 13 can smoothly collect the plastic sheets cut by the punching punch 2.

[0040] The working principle of the present utility model is as follows: The user drives the punching box 3 through the telescopic motor in the plastic punching machine 1. The user places the plastic packaging box to be punched between the punching head 2 and the spring 10, causing the punching box 3 to start sliding on the outer wall of the plastic punching machine 1. Under the restriction of the collecting plate 12, the spring 10 is in contact with the outer wall of the collecting plate 12. At this time, the telescopic rod 15 in the telescopic rod base 9 starts to slide in the telescopic rod base 9. When the bottom horizontal plane of the plastic punching machine 1 coincides with the top horizontal plane of the spring 10, the plastic packaging box is cut by the punching head 2. At this time, the telescopic rod base 9 on the outer wall of the spring 10 drives the first connecting rod 5 and the second connecting rod 6 to rotate in the punching head 2 under the restriction of the collecting plate 12. Under the restriction of the first coupling shaft 4, the second connecting rod 6 rotatably connected to the telescopic rod base 9 starts to rotate on the outer wall of the first coupling shaft 4. At the same time, the first connecting rod 5 slidably connected to the second connecting rod 6 also rotates on the outer wall of the first coupling shaft 4, thereby driving the second coupling shaft 7 to slide in the punching box 3, causing the push rod 8 to slide in the punching box 3. As the plastic punching machine 1 further punches, the bottom horizontal plane of the push rod 8 starts to contact the plastic sheet. Then, the plastic sheet cut by the plastic punching machine 1 is pushed by the push rod 8 and smoothly enters the collecting box 13 through the chute provided in the spring 10 due to the restriction of the collecting plate 12, ensuring that the user can smoothly collect the plastic sheet;

[0041] With the end of the punching, the plastic punching machine 1 drives the punching box 3 to reset. At this time, under the restriction of the punching box 3, the spring 10 pushes the limiting block 14, thereby driving the telescopic rod base 9 to start sliding in the punching box 3, ensuring that the telescopic rod base 9 resets under the action of the spring 10.
