[0037] The working principle and use process of the utility model are as follows: when it is necessary to punch holes in the packaging box, the moving rod 13 and the abutting plate 14 are moved forward by pulling the pull rod 18. At this time, the moving rod 13 drives the limiting ring 16 to move forward to contract the spring 17. Then, the packaging box is placed on the inner side of the U-shaped frame 6 so that the rear side of the packaging box fits with the rear side of the inner wall of the U-shaped frame 6. Then, the pull rod 18 is released to make the spring 17 rebound and push the limiting ring 16, the moving rod 13 and the abutting plate 14 to move in the direction close to the U-shaped frame 6 to abut and limit the packaging box. Finally, Just start the cylinder 3 to push the puncher 4 to punch holes in the packaging box. By starting the servo motor 83, the output end of the servo motor 83 can drive the screw rod 84 to rotate. The rotation of the screw rod 84 can drive the connecting plate 81 to move. The movement of the connecting plate 81 can drive the placement plate 5 to move left and right, so that the user can punch holes in different positions of the packaging box in the horizontal direction. When it is necessary to punch holes on other surfaces of the packaging box, first pull the pull rod 18 to drive the clamping plate 14 away from the packaging box, and then take out the packaging box and turn it over and use the same steps to position and punch holes in the packaging box.

[0038] To sum up: this packaging box punching device, by setting up a U-shaped frame 6, can temporarily position the packaging box placed inside it, thereby solving the problem that since the device does not have a structure for positioning the packaging box, when the cutting cylinder punches the packaging box, it will produce a certain pressure on the packaging box, which may easily cause a slight displacement of the packaging box, and then cause the punching position to shift, thereby reducing the qualified rate and aesthetics of the finished product and causing irreparable losses.
