[0021] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, the utility model is an anti-displacement punching device for carton production, comprising a workbench 1, a support frame 2 is provided on one side above the workbench 1, a fixed block 3 is provided in the middle of the support frame 2 close to the workbench 1, a threaded rod 4 is inserted in the middle of the fixed block 3, the threaded rod 4 is threadedly connected to the fixed block 3, both ends of the threaded rod 4 are movably connected to the mounting frame 5, a first motor 6 is provided above the mounting frame 5, the first motor 6 can drive the threaded rod 4 to rotate, when the threaded rod 4 rotates, the threaded rod 4 can move vertically on the fixed block 3, and the mounting frame 5 is also moved by the transmission of the threaded rod 4, and the mounting frame 5 is away from the lower end of the side of the supporting frame 2, a second motor 8 is fixedly installed on the mounting plate 7, the rotating shaft of the second motor 8 passes through the mounting plate 7 and is fixedly connected to the punching punch 9, and when the second motor 8 is working, the second motor 8 drives the punching punch 9 to rotate, When 5 moves in the vertical direction, the rotating punching punch 9 can complete the punching work of the carton. The workbench 1 is provided with L-shaped fixing plates 10 on both sides of the support frame 2, and connecting rods 11 are inserted on both sides of the L-shaped fixing plate 10. The connecting rods 11 and the L-shaped fixing plates 10 are movable between the two connecting rods 11 on the same side of the workbench 1 and are fixedly connected to the pressing plate 12 below. The two connecting rods 11 on the same side of the workbench 1 are fixedly connected by pull rods 13 above. The connecting rods 11 are located between the L-shaped fixing plate 10 and the pressing plate 12 and are sleeved with springs 14. When the pull rods 13 are pulled, the pressing plate 12 is also moved by the transmission of the connecting rods 11. When the carton is located under the pressing plate 12, the pressing plate 12 squeezes the carton under the action of the spring 14. Therefore, the carton can be stably fixed above the workbench 1 through the mutual cooperation between the pressing plate 12 and the workbench 1.

[0023] An anti-slip cover 15 is provided on the outside of the pull rod 13 . The provision of the anti-slip cover 15 effectively increases the friction between the palm and the anti-slip cover 15 , thereby making it easier to pull the pull rod 13 .

[0024] A rubber pad 16 is provided under the pressing plate 12 , and the rubber pad 16 can protect the contact surface between the pressing plate 12 and the carton, thereby reducing the probability of indentation on the carton.

[0027] The rotating shaft of the first motor 6 is fixedly connected to the threaded rod 4 via a coupling 20 . The provision of the coupling 20 effectively increases the rotational stability of the threaded rod 4 .

[0028] When the pull rod 13 is pulled, the pressure plate 12 is also moved through the transmission of the connecting rod 11. When the carton is located under the pressure plate 12, the pressure plate 12 squeezes the carton under the action of the elastic force of the spring 14, so that the carton can be stably fixed above the workbench 1 through the mutual cooperation between the pressure plate 12 and the workbench 1. The first motor 6 can drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, the threaded rod 4 can move vertically on the fixed block 3. The mounting frame 5 is also moved through the transmission of the threaded rod 4. When the second motor 8 is working, the second motor 8 drives the punching punch 9 to rotate. When the mounting frame 5 moves vertically, the rotating punching punch 9 can complete the punching of the carton.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
