[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a cardboard cutter with a feeding structure, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a base plate 1. A mounting frame 2 and a working plate 12 are fixedly connected to the top of the base plate 1. An electric push rod 3 is fixedly connected to the top of the mounting frame 2. The movable end of the electric push rod 3 extends into the interior of the mounting frame 2 and is fixedly connected to a lifting plate 4. A cutter 5 and a slide cylinder 9 are fixedly connected to the bottom of the lifting plate 4. A slide rod 8 is slidably connected inside the slide cylinder 9. The bottom end of the slide rod 8 extends to the outside of the slide cylinder 9 and is fixedly connected to a pressure plate 6. A spring 7 is fitted on the side surfaces of the slide cylinder 9 and the slide rod 8. The top end of the spring 7 is fixedly connected to the bottom of the lifting plate 4, and the bottom end of the spring 7 is fixedly connected to the top of the pressure plate 6.

[0019] A limiting block 10 is fixedly connected to the side surface of the slide rod 8, and a limiting groove 11 is opened on the side surface of the slide cylinder 9. The limiting groove 11 is connected to the inner cavity of the slide cylinder 9, and the limiting block 10 is inserted into the inside of the limiting groove 11.

[0020] After the cardboard moves to the bottom of the cutter 5, the operator can activate the electric push rod 3. When the electric push rod 3 moves the lifting plate 4 downward, the pressure plate 6 and the cutter 5 will also move downward simultaneously. When the pressure plate 6 contacts the cardboard, the cardboard will squeeze the pressure plate 6, causing the pressure plate 6 to slide the slide rod 8 inside the slide cylinder 9, while compressing the spring 7. When the electric push rod 3 continues to move the lifting plate 4 downward, the counterforce of the spring 7 will push the pressure plate 6, making it stick tightly to the cardboard. The contact area between the pressure plate 6 and the cardboard is large, which enhances the stability of the cardboard and reduces the possibility of the cardboard warping. At the same time, the cutter 5 can cut the cardboard. After the cutting work is completed, when the electric push rod 3 moves the lifting plate 4 upward, the spring 7 will release the pressure and drive the slide rod 8 and the pressure plate 6 to return to their original positions.

[0021] Furthermore, in order for the movable plate 15 to push the cardboard to move, such as Figure 1 , Figure 3 and Figure 4 As shown, a first groove 13 is provided on the top of the working plate 12, and the first groove 13 is connected to the inner cavity of the working plate 12. A second groove 14 is provided on both sides of the working plate 12, and the second groove 14 is connected to the inner cavity of the working plate 12.

[0022] The working plate 12 is slidably connected to a movable plate 15. The top of the movable plate 15 is fixedly connected to a first connecting post 16. The top of the first connecting post 16 extends to the outside of the working plate 12 through a first sliding groove 13 and is fixedly connected to a push plate 17. The two sides of the movable plate 15 are fixedly connected to second connecting posts 18, which are inserted into the inside of the second sliding groove 14.

[0023] A first mounting block 19 is fixedly connected to one side of the working plate 12. A lead screw 20 is rotatably connected to the first mounting block 19. A ball nut 21 is screwed onto the side surface of the lead screw 20. One side of the ball nut 21 is fixedly connected to one end of a second connecting post 18 away from the moving plate 15. A motor 22 is fixedly connected to the top of the base plate 1. The output end of the motor 22 is fixedly connected to one end of the lead screw 20.

[0024] A second mounting block 23 is fixedly connected to the side of the working plate 12 away from the first mounting block 19. A limit rod 24 is fixedly connected to the second mounting block 23. A slider 25 is slidably connected to the side surface of the limit rod 24. One side of the slider 25 is fixedly connected to the end of another second connecting post 18 away from the moving plate 15.

[0025] After the motor 22 is started, the output end of the motor 22 can drive the lead screw 20 to rotate. When the lead screw 20 rotates, the ball nut 21 will drive the moving plate 15 to move inside the working plate 12 due to the influence of the thread engagement. When the moving plate 15 moves, the first connecting column 16 will drive the push plate 17 to move synchronously. When the moving plate 15 moves, it can push the cardboard to move. In addition, when the moving plate 15 moves, the slider 25 will also slide synchronously on the side surface of the limiting rod 24. The slider 25 and the limiting rod 24 provide a limiting effect for the moving plate 15, reducing the possibility of the moving plate 15 deviating during the movement and improving the stability of the moving plate 15.

[0026] In order to improve the smoothness of the movement of the movable board 15, such as Figure 3 , Figure 4 and Figure 5 As shown, the movable plate 15 has an installation groove 26 inside, and a rotating shaft is fixedly connected inside the installation groove 26. A roller 27 is rotatably connected to the side surface of the rotating shaft, and the side surface of the roller 27 is in contact with the bottom inner wall of the working plate 12.

[0027] There is friction between the roller 27 and the inner wall of the working plate 12. When the moving plate 15 moves, the roller 27 will rotate on the shaft due to the influence of friction, thereby assisting the moving plate 15 to move, effectively reducing the friction when the moving plate 15 moves, and improving the smoothness of the moving plate 15.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
