[0038] See also Figure 1-5The utility model provides a technical solution: an anti-adhesion structure of a thermoplastic composite material cutting device, the anti-adhesion structure is installed at a corresponding position of the cutting machine, and includes: a knife holder 1 and a blade 4 connected to the knife holder 1; a driving component for driving the blade 4 to rotate to cut the material; the anti-adhesion structure also includes: cleaning components relatively arranged on both sides of the knife holder 1, so as to clean both sides of the blade 4 at the same time, and a brush plate 6 with bristles is provided; a cleaning component for cleaning the bristles; a linkage component, the linkage component is used to synchronously drive the brush plate 6 to contact the blade 4 and the cleaning component alternately when the blade 4 rotates, so that the bristles are cleaned by the cleaning component after cleaning the blade 4;

[0039] The above technical solution can be used to clean the material attached to the surface of the blade 4 after the blade 4 cuts the material. When in use, the driving component drives the blade 4 to rotate, and the blade 4 cuts the thermoplastic composite material. Heat is generated during cutting, so that hot melt appears on the surface of the material, and the hot melt adheres to the surface of the blade 4. Since a linkage component is provided, when the blade 4 rotates, it will synchronously drive the bristles on the surface of the brush plate 6 to move, and the surface of the blade 4 is cleaned by the bristles, thereby transferring the hot melt attached to the surface of the blade 4 to the surface of the bristles. After the bristles come into contact with the cleaning component, the cleaning component cleans the hot melt on the surface of the bristles, thereby maintaining the cleaning effect of the bristles on the blade 4 without attenuation, thereby overcoming the technical problem of the blade 4 sticking to the blade when cutting materials.

[0040] like Figure 1 and Figure 3 As shown, in this embodiment, the driving component includes: a motor bracket 2 connected to the blade holder 1; a driving motor 3 provided on the motor bracket 2, and an output shaft of the driving motor 3 is connected to the blade 4;

[0041] The above technical solution can drive the blade 4 to rotate. During operation, the driving motor 3 drives the blade 4 to rotate. After the blade 4 contacts the material, the material can be cut.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment, the cleaning assembly includes: a fixed plate 17 provided with a cleaning brush 19, the cleaning brush 19 is used to clean the bristles;

[0043] The above technical solution can be used to clean the bristles on the surface of the brush plate 6. When the brush plate 6 contacts the cleaning brush 19 under the action of the linkage assembly, the cleaning brush 19 will clean the bristles.

[0044] like Figure 2 and Figure 3As shown, in this embodiment, the linkage assembly includes: a cover body 5 and a movable plate 10 slidably arranged in the cover body 5. Specifically, sliders 12 are arranged at both ends of the movable plate 10, and the sliders 12 are slidably matched with slide rails 13 provided on the inner wall of the cover body 5. An elastic structure for connecting the movable plate 10 and the brush plate 6 is arranged between the movable plate 10 and the brush plate 6. A movable groove 7 for the bristles of the brush plate 6 to enter and exit is arranged on the side of the tool holder 1; a crank plate 8 connected to the output shaft of the driving motor 3; a rocker 9 movably connected to the crank plate 8 at one end, and a fixed column 11 is arranged between the other end of the rocker 9 and the movable plate 10;

[0046] The above technical solution can ensure that the bristles can clean the blade 4 when the blade 4 is running, and the cleaning effect is stable. When in use, when the output shaft of the driving motor 3 rotates, the crank disk 8 will be driven to rotate synchronously, and the crank disk 8 will drive the movable plate 10 to reciprocate up and down along the slide rail 13 on the inner wall of the cover body 5 through the rocker 9. This structure is a crank rocker structure. When the movable plate 10 moves up and down, it will synchronously drive the brush plate 6 to move along the movable groove 7, thereby cleaning the side of the blade 4, that is, when the movable plate 10 rises, the bristles on the surface of the brush plate 6 will clean the blade 4, and when the movable plate 10 descends, the second inclined surface 20 at the bottom of the brush plate 6 will cooperate with the first inclined surface 18 at the upper end of the fixed plate 17, thereby driving the brush plate 6 to retract into the inner wall of the cover body 5, and the bristles of the brush plate 6 will contact the cleaning brush 19 on the surface of the fixed plate 17, and the cleaning brush 19 will clean the bristles.

[0047] like Figure 2 and Figure 3 As shown, in this embodiment, the cover body 5 is detachably provided with a storage assembly for storing materials inside and directly below the cleaning brush 19; specifically, the storage assembly includes: a material storage box 21 with a storage cavity, a first thread groove 23 is provided on the side of the material storage box 21, and the first thread groove 23 is matched with a second thread groove 22 provided on the side of the cover body 5; a threaded rod 24 for connecting the first thread groove 23 and the second thread groove 22, and a rotating handle 27 is provided on the outer end of the threaded rod 24;

[0048] The above technical solution can be used to collect the material scraped from the blade 4. When a large amount of material is accumulated on the surface of the cleaning brush 19, the material solidifies after cooling and falls into the storage box 21 for collection. When the storage box 21 is full, the handle 27 is turned to drive the threaded rod 24 to rotate, so that the threaded rod 24 is disconnected from the first thread groove 23, so that the storage box 21 can be removed, which is conducive to material recovery.

[0051] Working principle: Before use, first install the anti-adhesion structure at the corresponding position of the cutting machine. When working, the driving motor 3 drives the blade 4 to rotate, and the blade 4 cuts the thermoplastic composite material. Heat is generated during cutting, so that hot melt appears on the surface of the material. The hot melt adheres to the surface of the blade 4. When the output shaft of the driving motor 3 rotates, it will synchronously drive the crank plate 8 to rotate. The crank plate 8 drives the movable plate 10 to reciprocate up and down along the slide rail 13 on the inner wall of the cover body 5 through the rocker 9. This structure is a crank rocker structure. When the movable plate 10 moves up and down, it will synchronously drive the brush plate 6 to move along the slide rail 13 on the inner wall of the cover body 5. As the movable groove 7 moves, the side of the blade 4 is cleaned, that is, when the movable plate 10 rises, the bristles on the surface of the brush plate 6 will clean the blade 4, and when the movable plate 10 descends, the second inclined surface 20 at the bottom of the brush plate 6 will cooperate with the first inclined surface 18 at the upper end of the fixed plate 17, thereby driving the brush plate 6 to retract into the inner wall of the cover body 5, and the bristles of the brush plate 6 will contact the cleaning brush 19 on the surface of the fixed plate 17, and the cleaning brush 19 will clean the bristles, thereby keeping the cleaning effect of the bristles on the blade 4 from being attenuated, thereby overcoming the technical problem of the blade 4 sticking to the knife when cutting materials.
