[0002] With the development of electric power, the erection of cables has also been greatly developed. When erecting high voltage, it is necessary to erect a tower to complete the installation of the cable. When erecting a tower, a large amount of steel plates are required. Since the lengths of the steel plates used for erecting towers at different heights are different, it is necessary to cut different steel plates through a cutting device.

[0003] After retrieval, the utility model with the patent number CN216099140U and the name of sheet cutting device includes a frame, a cutting device and a limiting plate. Through research and analysis, it is found that although the sheet cutting device has advantages such as the function of limiting the sheet at different angles, to a certain extent, there are still the following disadvantages;

[0004] For example: the sheet cutting device lacks a corresponding conveying structure, so that when cutting sheets of different sizes, the user needs to push and position them for cutting, which greatly reduces the efficiency of sheet cutting and has poor practicability. There is no dust removal structure on the cutting device, and waste chips are likely to float around during use, and the generated waste chips cannot be efficiently collected. The waste chips falling on the cutting platform will affect subsequent cutting, and the waste chips falling on other parts of the cutting device may be difficult to clean. To solve the above technical problems, it is very necessary for us to design a sheet cutting device for communication towers to solve the above problems. Summary of the Utility Model

A transmission belt 13 is movably sleeved between the rotating shaft of the motor 12 and the roller shaft 10. A telescopic plate 15 is welded to the top of the workbench 1. An electric telescopic rod 16 is arranged through the surface of the telescopic plate 15. One end of the electric telescopic rod 16 is fixedly connected to a toothed plate 17. The gear 14 and the toothed plate 17 are meshed. The telescopic plate 15 and the top plate 3 are welded, and a driving motor 18 is welded to the surface of the telescopic plate 15.

[0021] Please refer to Figure 2 and Figure 3 , both ends of the screw rod 4 are respectively rotatably connected to the surface of the telescopic plate 15. The rotating shaft of the driving motor 18 passes through the telescopic plate 15 and is fixedly connected to one end of the screw rod 4. By providing the telescopic plate 15, the relative position of the toothed plate 17 can be maintained when it is forced to move, improving the displacement use of the top plate 3.

[0022] Please refer to Figure 2 , a bearing is movably connected between the rotating shaft of the driving motor 18 and the inner wall of the telescopic plate 15. One side of the bearing is fixedly connected to the inner wall of the telescopic plate 15. The bearing is movably sleeved on the surface of the rotating shaft of the driving motor 18. By providing the bearing, the stable connection between the rotating shaft of the driving motor 18 and the inner wall of the telescopic plate 15 can be achieved, facilitating the rotation of the rotating shaft of the driving motor 18.

[0023] Please refer to Figure 1 and Figure 3 , the dust removal mechanism 8 includes a loading frame 19 which is welded to the top plate 3. A chip suction pump 20 is communicated with the top of the loading frame 19. One end of the chip suction pump 20 is communicated with a suction pipe 21. By providing the suction pipe 21, it is convenient for the chip suction pump 20 to be connected to the chip suction hood 22 assembly for realizing the conveying of particles. A chip suction hood 22 is fixedly arranged on the surface of the screw sleeve 5. A telescopic rod 23 is fixedly connected to the surface of the chip suction pump 20 through a cross plate. A clamping plate is welded to the bottom of the telescopic rod 23. By providing the clamping plate, the pressure roller 24 can be horizontally supported, enabling an indirect connection between the telescopic rod 23 and the pressure roller 24. A pressure roller 24 is rotatably connected to the inner cavity of the clamping plate.

[0024] Please refer to Figure 3 , a frame door is movably connected to the surface of the loading frame 19 through a hinge. A handle is welded to the surface of the frame door. By providing the handle, the contact area between the user and the frame door is increased, facilitating the inclined opening and closing of the frame door.

[0025] During use, the staff place the board on the workbench 1, and start the rotation of the shaft of the motor 12 through the peripheral controller to drive the conveyor belt 13 and the gear 14 to rotate cyclically. The rotation of the conveyor belt 13 causes the roller 10 to roll and push the wooden board on the surface to move horizontally, so as to transport the wooden board backward according to the cutting and using area, and start the telescopic movement of the electric telescopic rod 16 through the peripheral controller to push the toothed plate 17 to move horizontally, and adjust and install the distance between the teeth on the surface of the toothed plate 17 and the gear 14. The meshing rotation of the toothed plate 17 and the gear 14 drives the toothed plate 17, the electric telescopic rod 16 and the telescopic plate 15 to move downward. The downward movement of the telescopic plate 15 compresses and drives the top plate 3, the cutting knife 7 and the pressure roller 24 to move downward. Start the rotation of the shaft of the rotation motor 6 through the peripheral controller to drive the cutting knife 7 to cut the board on the workbench 1. When the teeth on the surface of the toothed plate 17 are far away from the gear 14 and disengaged from the meshing by the electric telescopic rod 16, the cutting knife 7 is reset along with the reset of the telescopic plate 15. The rolling of the roller 10 can push the board to move backward continuously for automatic transportation and cutting. Start the rotation of the shaft of the drive motor 18 through the peripheral controller to drive the screw 4 and the nut 5 to be threadedly connected to push the nut 5, the cutting knife 7, the telescopic rod 23 and the pressure roller 24 to move horizontally. The elastic supporting force of the telescopic rod 23 makes the pressure roller 24 tightly contact the surface of the board, so as to buffer, press and limit the board. The displacement of the cutting knife 7 can cut different positions of the board according to requirements. Due to the waste chips generated during cutting, some can directly fall through the chip dropping through hole 9, and some can fall on the workbench 1. Start the chip suction pump 20 through the peripheral controller to form a negative pressure at the chip suction cover 22 and the chip dropping through hole 9, forcing the waste chips to move towards the chip suction cover 22 and be sucked away, and enter the loading frame 19 from the chip suction pump 20 through the suction pipe 21. Therefore, this cutting equipment can clean the waste chips while cutting.

[0026] To sum up: The board cutting equipment for the communication tower solves the problems that workers are prone to fatigue and reduce the efficiency of board cutting, and it is impossible to efficiently collect the generated waste chips through the cooperation of the workbench 1, the conveying mechanism 2, the top plate 3, the screw 4, the nut 5, the rotation motor 6, the cutting knife 7, the dust removal mechanism 8 and the chip dropping through hole 9.
