[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These 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.

[0022] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the sliding cutting part of this utility model.

[0023] As attached Figure 1As shown, a bristle-cutting roller brush includes a roller 1 and a roller brush frame 2. The roller 1 is rotatably connected to the roller brush frame 2, and bristle strips are wrapped on the roller 1. The roller brush frame 2 is connected to a fixed blade 6 through a positioning device 5. A sliding cutting part 7 is slidably connected to the roller brush frame 2. A return spring 8 is connected between the sliding cutting part 7 and the roller brush frame 2. A rotating mechanism 3 is installed on the roller brush frame 2, and a cam 4 for pushing the sliding cutting part 7 is installed on the rotating mechanism 3.

[0024] The rotating mechanism 3 includes a motor 31, a driving gear 32, and a driven gear 33. The driving gear 32 is fixed on the output shaft of the motor 31. The driving gear 32 meshes with the driven gear 33. A cam 4 is fixed on the driven gear 33. The driving gear 32 and the driven gear 33 are rotatably connected to the brush holder 2.

[0025] Motor 31 drives the drive gear 32 to rotate, which in turn drives the driven gear 33 to rotate, and the driven gear 33 drives the cam 4 to rotate.

[0026] As attached Figure 2 As shown, the sliding cutting part 7 includes a slider 71 and a moving blade 72. The slider 71 is slidably connected to the roller brush holder 2, and the moving blade 72 is fixed on the slider 71. The slider 71 and the moving blade 72 move linearly synchronously.

[0027] A bearing 9 is connected to the slider 71, and the bearing 9 is attached to the cam 4. The protrusion of the rotating cam 4 pushes the bearing 9 and the sliding cutting part 7 outward, at which time the return spring 8 is in a compressed state. When the protrusion of the cam 4 disengages from the bearing 9, the return spring 8 rebounds and drives the sliding cutting part 7 to move in the opposite direction to reset. The continuously rotating cam 4 can continuously drive the sliding cutting part 7 to move back and forth in a linear motion.

[0028] The positioning device 5 includes a column 51 and a spring 52. The spring 52 connects the column 51 to the roller brush holder 2. The moving blade 72 has an oblong hole 73, through which the column 51 passes. The column 51 presses the fixed blade 6 against the side wall of the roller brush holder 2. The spring 52 provides pressure to the column 51, allowing the column 51 to press the fixed blade 6 firmly against the side wall of the roller brush holder 2.

[0029] The roller brush holder 2 is connected to the arc-shaped transparent cover 10 by a positioning pin, and the roller 1 is located below the arc-shaped transparent cover 10.

[0030] A connecting frame 11 is fixed on the roller brush holder 2. The column 51 passes through the guide hole on the connecting frame 11, and a return spring 8 is connected between the slider 71 and the connecting frame 11. The column 51 can move linearly along the guide hole.

[0031] Both the moving blade 72 and the fixed blade 6 are equipped with toothed rows. The reciprocating moving blade 72, in conjunction with the stationary fixed blade 6, can cut the hair on the roller 1.

[0032] The motor 31 is a dual-head motor. The output shafts at both ends of the motor 31 are respectively fixed with a drive gear 32 and a drive synchronous pulley 12. One end of the roller 1 is fixed with a driven synchronous pulley 13. Both the drive synchronous pulley 12 and the driven synchronous pulley 13 are meshed on the synchronous belt 14.

[0033] The motor 31 can simultaneously drive the drive gear 32 and the drive synchronous pulley 12 to rotate. The drive synchronous pulley 12 drives the driven synchronous pulley 13 and the roller 1 to rotate via the synchronous belt 14.

[0034] The rotating mechanism 3 of this application drives the roller 1 to rotate while pushing the sliding cutting part 7 to move back and forth in a straight line repeatedly through the cam 4 and the return spring 8. The moving sliding cutting part 7, in conjunction with the stationary fixed blade 6, can continuously cut the hair on the roller 1, thereby avoiding hair entanglement.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
