The phrase appears in various places in the specification and is not necessarily meant to refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] Please refer to Figures 1-4 , the embodiments provided by the present utility model: A cardboard cutting device, comprising a base 1 and a movable seat 2. A through groove 16 is formed on the surface of the base 1 for two movable seats 2 to slide. The two movable seats 2 are symmetrically distributed for supporting and limiting. The internal dimensions of the through groove 16 are all adapted to the external dimensions of the bottom ends of the movable seats 2, improving the stability of the support of the movable seats 2. A servo motor 1 4 is fixedly provided at the middle position of the side wall of the base 1 through bolts. The output end of the servo motor 1 4 is fixedly provided with a bidirectional lead screw 5 through a coupling. A lead screw slide 1 3 is rotatably connected to the side walls of the two movable seats 2 close to the bidirectional lead screw 5. The two lead screw slides 1 3 are symmetrically threadedly connected to the outer surface of the bidirectional lead screw 5. Two groups of fastening clips 17 are rotatably connected to the surfaces of the movable seats 2 for clamping the edges of the board. A return spring 18 is fixedly provided on the surfaces of the movable seats 2 close to the fastening clips 17. The top ends of the return springs 18 are fixedly provided at the bottom ends of the fastening clips 17 in sequence. The operator can press the fastening clip 17 downward to open the fastening clip 17 to facilitate placing the board on the surface of the movable seat 2, and then release the fastening clip 17. The fastening clip 17 resets under the action of the elastic force of the return spring 18, thus facilitating clamping of boards of different thicknesses. When it is necessary to adjust the horizontal distance between the two fastening clips 17, the operator can drive the bidirectional lead screw 5 to rotate by starting the servo motor 1 4, thereby driving the two movable seats 2 to move towards each other, thus improving the convenience of adjusting the horizontal distance between the two fastening clips 17, and thus facilitating adaptation to cutting cardboard of different sizes, improving the adaptability of the device.

[0022] The surfaces of both movable seats 2 are provided with grooves 8. Inside each groove 8, there is a sliding connection with a slider 10. Both sliders 10 are cubes, and the external dimensions of the sliders 10 are adapted to the internal dimensions of the grooves 8, which improves the stability of the movement of the sliders 10. At the top of each slider 10, a cylinder 11 is fixedly installed through bolts. At the output end of each cylinder 11, a support frame 12 is fixedly installed through a coupling. The support frames 12 are all L-shaped and symmetrically distributed for support and limitation. On the side walls of the support frames 12, a second servo motor 13 is fixedly installed through bolts. The output ends of the second servo motors 13 all penetrate through the support frames 12 and a cutter head 14 is fixedly installed through a coupling. The two cutter heads 14 are symmetrically distributed. Starting the second servo motor 13 can drive the cutter head 14 to rotate. Starting the cylinder 11 can drive the cutter head 14 to move vertically for cutting. On the side walls of both movable seats 2, a third servo motor 15 is fixedly installed. At the output end of each third servo motor 15, a second lead screw 9 is fixedly installed. The other ends of the second lead screws 9 are rotatably connected to the side walls of the movable seats 2. On the outer surfaces of the second lead screws 9, two second lead screw sliders 19 are threadedly connected. The second lead screw sliders 19 are sequentially rotatably connected inside the sliders 10. Starting the third servo motor 15 can drive the second lead screw 9 and the second lead screw sliders 19 to rotate, thereby driving the sliders 10 to slide inside the grooves 8, thus facilitating the adjustment of the position of the cutter head 14.

[0023] On the side walls of both movable seats 2 close to the first lead screw slider 3, two chutes 7 are provided. Inside each chute 7, a round rod 6 is inserted. The two ends of the round rod 6 are sequentially fixedly installed on the inner side walls of the through slots 16, so that the movable seats 2 are slidably connected to the outer surface of the round rod 6, restricting the rotation of the movable seats 2 and improving the stability of the horizontal movement of the movable seats 2.

[0024] At the inner bottom of the through slot 16, a through slot 16 is provided. The through slot 16 penetrates through the bottom end of the base 1, facilitating the collection of debris by dropping.

[0025] Working principle: When this cardboard cutting device is in use, the operator first connects to an external power supply. The operator can press the fastening clip 17 under the box to open the fastening clip 17 to facilitate placing the board on the surface of the movable seat 2, and then release the fastening clip 17. The fastening clip 17 resets under the action of the elastic force of the return spring 18, thereby realizing the clamping of the board. Starting the second servo motor 13 can drive the cutter head 14 to rotate at high speed. Then starting the cylinder 11 can drive the cutter head 14 to move downward to contact the board for cutting. Then starting the third servo motor 15 drives the slider 10 to slide inside the groove 8, thereby driving the cutter head 14 to move horizontally along the edge of the board, thus realizing the cutting of the board. When it is necessary to adjust the distance between the fastening clips 17, starting the first servo motor 4 can drive the bidirectional lead screw 5 to rotate, thereby driving the two movable seats 2 to move towards each other, thus improving the convenience of adjusting the horizontal distance between the two fastening clips 17, thus facilitating the adaptation to cut cardboard of different sizes and improving the adaptability of the device.

[0026] Secondly, the two round rods 6 are symmetrically distributed and slide inside the chute 7 in sequence, so as to limit the rotation of the movable seat 2, thereby improving the stability of the horizontal adjustment of the movable seat 2.
