[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model provides a cutter protection plate 10 for a shredder, the specific structure of which is as follows:

[0027] A shredder includes guide rollers and several cutters evenly spaced along the circumference of the guide rollers. For example... Figure 1 and Figure 2 As shown, the cutter protection plate 10 for the shredder includes a plate body 11. The plate body 11 is located on the side of the cutter away from the center of the guide roller and abuts against the cutter. It can effectively prevent tobacco residue from accumulating on the surface of the cutter, thereby improving the quality of cigarette products.

[0028] To improve the corrosion resistance and surface smoothness of the cutter protection plate 10, and further reduce the possibility of soot and dust adhesion, an anti-adhesion layer is provided on the plate body 11 to prevent soot adhesion. The anti-adhesion layer can be a chrome-plated layer, a phosphated layer, a Teflon coating, etc., all of which can effectively prevent soot adhesion. Considering economic cost and implementation effect, in this embodiment, the anti-adhesion layer is preferably a chrome-plated layer.

[0029] like Figure 1As shown, the cutter protection plate 10 for the shredder also includes a limiting part disposed on the plate body 11 to limit the displacement of the cutter. The plate body 11 abuts against the first side of the cutter. The limiting part includes a limiting rod 12, which extends along the length of the plate body 11 and abuts against the second side of the cutter. The first side is perpendicular to the second side. The presence of the limiting rod 12 can prevent unnecessary displacement of the cutter during operation, thereby reducing friction between the cutter and the cutter protection plate 10 and extending the service life of the entire equipment. Specifically, the limiting part also includes two fixing grooves 13 disposed on the plate body 11 and fixing blocks 14 disposed in the fixing grooves 13. The two fixing grooves 13 are arranged sequentially along the length of the plate body 11. The fixing blocks 14 are provided with fixing holes for allowing the limiting rod 12 to pass through. The fixing blocks 14 can be through holes or blind holes. In use, the two ends of the limiting rod 12 are respectively disposed in the two fixing holes and abut against the second side of the cutter to prevent the cutter from moving in the vertical direction (within the vertical direction). Figure 1 (Taking the direction shown as an example) the movement occurs.

[0030] To facilitate the replacement and maintenance of the limiting rod 12, the fixing block 14 and the fixing groove 13 are detachably connected. The detachable connection can be achieved through snap-fit, pin-hole connection, etc. For ease of operation, in this embodiment, it is preferable that the fixing block 14 is snap-fitted into the fixing groove 13.

[0031] This utility model also provides a shredder, including the cutter protection plate 10 for the shredder as described above, such as... Figure 2 As shown, it also includes a blade holder 20, with the cutter installed inside the blade holder 20, and the cutter protection plate 10 connected to the blade holder 20.

[0032] To facilitate maintenance and replacement of the cutter protection plate 10, the cutter protection plate 10 and the cutter holder 20 are detachably connected by bolts.

[0033] like Figure 2 As shown, the cutter holder 20 is provided with a cutter feed system 21 for controlling the cutter to extend out of the cutter holder 20 and retract into the cutter holder 20. In order to allow the cutter to move in and out of the cutter holder 20 flexibly, one end of the cutter protection plate 10 is connected to the cutter holder 20, and the other end is provided with a gap 22 between the cutter protection plate 10 and the cutter holder 20 to allow the cutter to move in and out.

[0034] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.
