[0019] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please refer to Figure 1-5 A cigarette cutting tool includes a disc-shaped blade 1 made of stainless steel, which has high strength and corrosion resistance, ensuring that it is not easily deformed or damaged during long-term operation. The disc-shaped blade 1 has a cutting edge 14 around its circumference. When the disc-shaped blade 1 rotates at high speed, it cuts the cigarette through the surrounding cutting edge 14. The disc-shaped blade 1 has a mounting hole 11 at its center. A plurality of outwardly extending heat dissipation grooves 12 are arranged around the mounting hole 11. The heat dissipation grooves 12 are connected to the mounting hole 11. A fixing hole 13 is provided between every two adjacent heat dissipation grooves 12.

[0021] When in use, the disc-shaped cutter 1 frequently cuts cigarettes, so the cutter itself will carry a certain amount of heat due to frictional cutting. The multiple heat dissipation grooves 12 can not only reduce the overall weight, but also increase the contact area between the cutter and the air, thereby accelerating the heat dissipation of the cutter and improving the service life of the cutter.

[0022] The heat dissipation groove 12 is elongated, and each heat dissipation groove 12 is eccentrically located around the mounting hole 11; that is, the center of the heat dissipation groove 12 and the center of the mounting hole 11 are not on the same straight line. The multiple heat dissipation grooves are staggered, which can improve the heat dissipation efficiency when rotating.

[0023] To ensure the stability of the disc-shaped cutter 1 during use, an upper cutter holder 2 is provided above the disc-shaped cutter 1. An integrally formed drive shaft 21 is provided on the bottom surface of the upper cutter holder 2. A lower cutter holder 3 is provided below the disc-shaped cutter 1. The drive shaft 21 passes through the lower cutter holder 3 at the mounting hole 11 and extends outward. The upper cutter holder 2, the disc-shaped cutter 1, and the lower cutter holder 3 are fixedly connected at the fixing hole 13 by bolts. In other words, the upper cutter holder 2 and the lower cutter holder 3 clamp and fix the disc-shaped cutter 1, making the three parts a single unit, which facilitates stable rotation and cutting.

[0024] In this embodiment, a drive box 6 is also included to drive the drive shaft 21 to rotate. The surface of the drive box 6 is provided with a fixed tube 5. The drive shaft 21 extends into the drive box 6 inside the fixed tube 5. The bottom end of the drive shaft 21 is rotatably connected to the inner bottom wall of the drive box 6. A drive gear 22 is provided around the circumference of the drive shaft 21. An active gear 71 that meshes with the drive gear 22 is provided inside the drive box 6. The active gear 71 is connected to a motor 7 on the surface of the drive box 6. After the motor 7 runs, it drives the disc-shaped cutter 1 to rotate.

[0025] In other words, the motor 7 drives the drive gear 22 to rotate through the drive gear 71. Since the drive gear 22 is fixed on the circumference of the drive shaft 21, the drive wheel can rotate together with the upper knife holder 2, the disc-shaped cutter 1 and the lower knife holder 3 when the drive wheel rotates, thereby realizing the use of the disc-shaped cutter 1 to cut the cigarette.

[0026] Among them, a reducer or accelerator can be installed on the output shaft of the motor 7 as needed. The reducer can reduce the speed of the motor and improve the stability of the rotation of the disc-shaped tool 1.

[0027] As a preferred embodiment, a semi-circular blade cover 4 is also provided around the disc-shaped cutter 1. The semi-circular blade cover 4 is fitted around the outer circumference of the disc-shaped cutter 1 to provide safety protection and prevent foreign objects from accidentally touching the cutter.

[0028] The blade cover 4 is also provided with an integrally formed semi-circular connecting cylinder 41 below it, and a connecting plate 51 is provided around the port of the fixing tube 5. The connecting cylinder 41 and the connecting plate 51 are fixedly connected by bolts. Since the blade cover 4 and the connecting cylinder 41 are integrally formed, the connecting cylinder 41 and the connecting plate 51 can ensure the stability of the blade cover to meet the safety protection requirements and have strong practicality.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
