[0026] The following is combined with Figures 1-4 Through specific embodiments and application scenarios, this utility model provides a detailed description of a cutter roller assembly with anti-scratch function and a shredder.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a cutter roller assembly with anti-scratch function, including: a cutter roller 1 and a protective component 2. A plurality of blades 11 are sequentially arranged circumferentially on the cutter roller 1. The protective component 2 includes a protective main plate 21 and a fixing member 22. The protective main plate 21 extends axially along the cutter roller 1. The protective main plate 21 is detachably disposed on the outside of the blades 11 by means of the fixing member 22 to cover the cutting edge 111 of the blades 11.

[0028] In a shredder, multiple blades 11 are arranged circumferentially on the outer wall of the cutter roller 1. During rotation, the cutter roller 1 is cut by these blades 11. To facilitate the feeding of tobacco shreds to the cutter roller 1, at least some of the blades 11 are typically suspended above the cutting window of the shredder. When maintenance personnel need to clean or repair the cutter roller 1, the limited space results in a close proximity to the roller 1, posing a safety risk of being scratched by the blades 11. This invention provides a cutter roller assembly with anti-scratch function, such as... Figure 1As shown in the drawings, the protective main plate 21 is in a long strip shape and extends along the extension direction of the cutting edge 111 of the blade 11. The length of the protective main plate 21 can be consistent with the length of the blade 11 to ensure that the protective main plate 21 can cover the cutting edge 111 of the blade 11. Optionally, the protective main plate 21 can be a steel plate. Optionally, the fixing member 22 can be a magnetic buckle, a screw or a buckle.

[0029] When the knife roll 1 stops working, the fixing member 22 is used to fix the protective main plate 21 at the cutting edge 111 of the blade 11, so that the cutting edge 111 of the blade 11 is covered by the protective main plate 21, thereby avoiding the maintenance personnel from being scratched. When the knife roll 1 needs to cut tobacco, the fixing member 22 is detached from the blade 11, so that the protective main plate 21 and the blade 11 are separated.

[0030] As shown in the drawings, Figure 2 the outer side of the protective main plate 21 is further provided with a plurality of safety marks 26, and the plurality of safety marks 26 are sequentially and spaced apart along the axial direction of the protective main plate 21. The color of the safety mark 26 can be a more eye-catching color such as red, yellow or black. The plurality of safety marks 26 with different colors are alternately arranged, so that the maintenance personnel can timely find the position of the blade 11 and improve the vigilance of the maintenance personnel.

[0031] The utility model provides a kind of knife roll assembly with anti-scratch function, the circumferential direction of knife roll 1 is sequentially provided with multiple blades 11, to be cut by blade 11 in the process of the rotation of knife roll 1 Tobacco, protective main plate 21 extends along the axial direction of blade 11, and protective main plate 21 is detachably arranged on the outer side of blade 11 by fixing member 22, when it is needed to clean or maintain knife roll 1, protective main plate 21 is fixed on the outer side of blade 11 by fixing member 22, so that the cutting edge 111 of blade 11 is covered by protective main plate 21, thereby avoiding maintenance personnel from being scratched by blade 11, and eliminating security risks.

[0032] Further, in some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , the first side edge of the axial direction of the protective main plate 21 has a first bending edge 211, and the first bending edge 211 is used to cover the cutting edge 111 of the blade 11.

[0033] The first bending edge 211 is formed by precise folding process and is designed to cover the cutting edge 111 of the blade 11. The protective main plate 21 is made of high-strength material to ensure that it can effectively cover the cutting edge 111 of the blade 11 during use. The curvature and width of the first bending edge 211 are optimized to tightly fit the blade 11 to provide better protection effect and avoid accidental injury.

[0034] In some embodiments, as shown inFigure 2 As shown, the protection assembly 2 further comprises a telescopic plate 23. The telescopic plate 23 is telescopically arranged at one end of the protection main plate 21. The telescopic plate 23 and the protection main plate 21 are coaxially arranged.

[0035] Optionally, the telescopic plate 23 can be a steel plate. The safety mark 26 is pasted on the steel plate. When the specifications of the knife roll 1 and the blade 11 change, the effective covering length of the protection main plate 21 to the cutting edge 111 of the blade 11 is changed through the telescopic movement of the telescopic plate 23. For example, when the length of the blade 11 is relatively long, the telescopic plate 23 is extended from the protection main plate 21, and the telescopic plate 23 and the protection main plate 21 cover the cutting edge 111 of the blade 11 at the same time, so as to ensure that all areas of the cutting edge 111 of the blade 11 are covered and the safety hazard is eliminated. When the length of the blade 11 is relatively short, the telescopic plate is controlled to retract into the protection main plate 21, so as to ensure that the length of the protection main plate 21 is adapted to the length of the blade 11. Thus, the user can control the extension length of the telescopic plate 23 according to the specifications of the knife roll 1 and the blade 11, so as to ensure that the entire protection assembly 2 can cover the cutting edges of blades of different specifications, and the versatility is good.

[0036] As shown in the Figure 2 The protection assembly 2 further comprises an adjusting piece 24. The protection main plate 21 and the telescopic plate 23 are correspondingly provided with a first strip-shaped hole 212 and a second strip-shaped hole 231. The fixing piece 22 is located on the side of the telescopic plate 23 away from the protection main plate 21. The adjusting piece 24 has an end cap. The adjusting piece 24 is arranged in the first strip-shaped hole 212 and the second strip-shaped hole 231 and is inserted into the fixing piece 22, so as to lock the telescopic plate 23 and the protection main plate 21 to the fixing piece 22, and the fixing piece 22 and the blade 11 are detachably connected.

[0037] Specifically, the first strip-shaped hole 212 extends along the axial direction of the protection main plate 21. The extension direction of the second strip-shaped hole 231 is parallel to the extension direction of the protection main plate 21. At least part of the telescopic plate 23 is overlapped on the inner side of the protection main plate 21. The fixing piece 22 is located on the inner side of the telescopic plate 23.

[0038] Optionally, the adjusting member 24 is a bolt. The screw rod of the bolt is arranged in the first strip-shaped hole 212 and the second strip-shaped hole 231 and is inserted into and threadedly connected with the fixing member 22. With the screw rod screwed in, the end cap of the bolt tightly abuts the extendable plate 23 and the protection main plate 21 against the fixing member 22, thereby achieving the fixed connection of the extendable plate 23 and the protection main plate 21. When it is necessary to adjust the extended length of the extendable plate 23, the bolt is screwed to make the screw rod retreat to the first strip-shaped hole 212, and then the extendable plate 23 is manually moved to make the extended length of the extendable plate 23 meet the requirement, and then the screw rod and the fixing member 22 are threadedly connected to lock the extendable plate 23 and the protection main plate 21 to the fixing member 22.

[0039] Optionally, the fixing member 22 is a neodymium magnet buckle. As shown in Figure 3 , the neodymium magnet buckle has a through hole 221 for the insertion of the adjusting member 24. Specifically, the adjusting member 24 is inserted into the through hole 221, and with the insertion of the adjusting member 24, the fixing member 22, the extendable plate 23 and the protection main plate 21 are fixed together. The blade 11 is a magnetic metal blade 11, the neodymium magnet buckle and the magnetic metal blade 11 have different magnetic poles, and the neodymium magnet buckle and the magnetic metal blade 11 are magnetically attracted, thereby fixing the protection assembly 2 to the outer side of the blade 11. When it is necessary to disassemble, the neodymium magnet buckle only needs to be removed from the blade 11, and the entire protection assembly 2 can be disassembled from the blade 11, which is very convenient.

[0040] In some embodiments, as shown in Figure 2 , the protection assembly 2 further includes an operating handle 25. The operating handle 25 is fixed to the end cap to facilitate the user to hold and operate the operating handle 25 to manipulate the adjusting member 24 without the aid of a wrench or other tools, thereby improving the operation convenience when adjusting the extended length of the extendable plate 23 and facilitating the use.

[0041] As shown in Figure 4 , the first side edge and the second side edge of the protection main plate 21 in the axial direction respectively have a first bending edge 211 and a second bending edge 213. The first bending edge 211 and the second bending edge 213 respectively slide in contact with the two side edges of the extendable plate 23 in the axial direction to guide the axial movement of the extendable plate 23 along the protection main plate 21.

[0042] The first bending edge 211 and the second bending edge 213 can form sliding contact with the two side edges of the extendable plate 23 in the axial direction. This contact mode can effectively guide the smooth movement of the extendable plate 23 in the axial direction of the protection main plate 21, improve the stability of the extendable plate 23, and also enhance the flexibility and reliability of the entire protection assembly 2, making it more convenient for the user to adjust the extended length of the extendable plate 23.

[0043] In order to achieve the preferable sliding performance of the telescopic plate 23, the surfaces of the first bending edge 211 and the second bending edge 213 are smooth surfaces, so as to reduce the abrasion and resistance during the movement of the telescopic plate 23.

[0044] Further, as shown in Figure 2 and Figure 3 , the first side edge of the telescopic plate 23 in the axial direction has a protection edge 232 for covering the cutting edge 111 of the blade 11. The first side edge of the telescopic plate 23 in the axial direction is located on the same side as the first side edge of the protection main plate 21 in the axial direction. When the protection assembly 2 is installed on the blade 11, the telescopic plate 23 extends out of the protection main plate 21 and is attached to the outer side of one end of the blade 11, so as to cover all areas of the cutting edge 111 by means of the first bending edge 211 and the protection edge 232, thereby ensuring the safety protection of the protection assembly 2 to the maintenance personnel and avoiding the maintenance personnel from being scratched by the blade 11. At the same time, the protection edge 232 is arranged on the first bending edge 211, and the axial movement of the protection edge 232 of the protection main plate 21 is guided by the first bending edge 211, so as to ensure the flexibility of the telescopic plate 23 during the telescopic movement.

[0045] As shown in Figure 2 , the outer side of the telescopic plate 23 is also provided with a safety mark 26, so as to remind the maintenance personnel to pay attention to safety.

[0046] In some embodiments, as shown in Figure 2 and Figure 3 , the telescopic plate 23 has two. The two telescopic plates 23 are respectively and telescopically arranged at opposite ends of the protection main plate 21, so as to further flexibly adjust the effective protection length of the entire protection assembly 2 and improve the universality of the protection assembly 2, thereby ensuring that the effective protection length of the protection assembly 2 can be adapted to different specifications of the knife roller 1 and the blade 11. In this embodiment, the installation modes of the two telescopic plates 23 can be the same, and the specific assembly mode between the telescopic plate 23 and the protection main plate 21 can be referred to the above-described embodiments, which will not be described here.
