Description

Technical Field

[0001] This utility model relates to the field of cigarette making machines, specifically a blade guard that facilitates the replacement of the cutting blade. Background Technology

[0002] The ZJ17 cigarette rolling machine is a high-speed rolling and forming equipment widely used in my country's tobacco industry. It is manufactured domestically by Chinese cigarette machine companies after introducing German technology. It integrates mechanical, electrical, pneumatic, and hydraulic technologies and features high production efficiency, strong operational stability, and reliable cigarette quality.

[0003] In the existing technology, the cutter head of the ZJ17 cigarette making machine is usually equipped with a protective cover. When the inner cutter is inspected, the protective cover needs to be opened first. During use and observation, it was found that the protective cover and the machine housing are simply connected by a hinge. Therefore, when disassembling the cutter head, the protective cover needs to be continuously supported or temporarily supported by objects such as paper rings. These support methods have problems such as high manpower consumption or significant safety hazards, and are not convenient for the disassembly of the cutter head.

[0004] Therefore, a blade guard that facilitates blade replacement is proposed to address the above issues. Utility Model Content

The bristles in the cleaning ring 33 can clean the threads on the surface of the screw 15, reduce the debris remaining in the threads on the surface of the screw 15, and ensure stable threaded transmission between the screw 15 and the sleeve 14.

[0024] Please see Figure 5 As shown, the inner wall of the hanging ring 17 is rotatably connected with a ratchet 4, and the ratchet 4 and the hanging ring 17 are connected by a torsion spring; the ratchet 4 has an arc-shaped structure; by setting the ratchet 4, when the hook 16 is inserted into the hanging ring 17, the arc-shaped outer wall of the ratchet 4 will not cause too much obstruction to the hook 16. When the hook 16 has a tendency to sway, the ratchet 4 will provide additional resistance to the hook 16, thereby improving the stability of the hook 16 inside the hanging ring 17. In addition, when it is necessary to remove the hook 16 from the hanging ring 17, the ratchet 4 can be pulled to rotate along the hanging ring 17 and change its angle so that it no longer obstructs the hook 16, and then the hook 16 can be removed from the hanging ring 17.

[0025] Please see Figure 5 As shown, a silicone 5 is fixed to the end of the hook 16; the silicone 5 is used to protect the hook 16 from wear; by setting the silicone 5, the outer wall of the hook 16 has an additional protective layer, which reduces the direct contact between the hook 16 and the hanging ring 17 during frequent insertion and exit, reduces the wear on the end of the hook 16, and extends the service life of the hook 16.

[0026] Please see Figure 3As shown, a sealing strip 6 is fixedly connected to the end of the protective cover 12; the outer wall of the sealing strip 6 has an arc-shaped structure; by setting the sealing strip 6, when the protective cover 12 seals and protects the cutter disc assembly 13, the sealing strip 6 can fill and seal the connection between the protective cover 12 and the cigarette machine housing 1, thereby improving the sealing performance of the protective cover 12 during protection, and at the same time reducing the direct contact and wear between the protective cover 12 and the cigarette machine housing 1 caused by processing errors.

[0027] Working principle: When it is necessary to disassemble and replace the cutter in the cutter assembly 13, the operator can pull the handle on one side of the protective cover 12 to lift the protective cover 12. The protective cover 12 will rotate along the cigarette machine housing 1, exposing the cutter assembly 13. After rotating the protective cover 12 to a suitable operating height, the screw 15 can be rotated to remove the hook 16 from the hook 18. The sleeve 14 and the protective cover 12 can rotate at multiple angles. By rotating the screw 15 several times, it moves along the sleeve 14. After adjusting the length of the rod formed by the screw 15 and the sleeve 14 to correspond with the hanging ring 17, the end of the hook 16 is inserted into the hanging ring 17 by holding the screw 15, thereby causing the protective cover 12 to be subjected to the rolling action. The support provided by the cigarette machine housing 1 to the hook 16 allows the protective cover 12 to be in a fixed position. Subsequently, the cutter assembly 13 can be disassembled from the cigarette machine housing 1 and its internal cutter replaced. It is worth noting that the specific connection method between the cutter assembly 13 and the cigarette machine housing 1 is a mature existing technology, and therefore will not be described in detail here. After the replacement work is completed, the hook 16 can be held inside the hook 18 by directly attaching the screw 15 to the surface of the hook 18 or by screwing it into the sleeve 14 a certain length, and the protective cover 12 can be reset. By setting the support plate 2 and the protrusion 22, when adjusting the length of the screw 15 sliding out relative to the sleeve 14, the operator can hold the screw 15 by holding the support plate 2. For operation control, the protrusion 22 increases the friction area on the surface of the support plate 2, thereby improving the stability of operation when rotating the support plate 2 and reducing slippage when rotating the screw 15. By setting the connecting plate 32 and the cleaning ring 33, after the hook 16 is inserted into the hanging ring 17 and the protective cover 12 is fixed, the connecting plate 32 can be pulled to move the cleaning ring 33 along the exposed threaded portion of the screw 15. The bristles inside the cleaning ring 33 can clean the threads on the surface of the screw 15, reducing residual debris and ensuring stable threaded transmission between the screw 15 and the sleeve 14. By setting the ratchet 4, when the hook 16 is inserted into the hanging ring 17, the arc of the ratchet 4... The outer wall of the hook 16 will not cause too much obstruction. When the hook 16 tends to sway, the ratchet 4 will provide additional resistance to the hook 16, thereby improving the stability of the hook 16 inside the hanging ring 17. In addition, when it is necessary to remove the hook 16 from the hanging ring 17, the ratchet 4 can be pulled to rotate along the hanging ring 17 and change its angle so that it no longer obstructs the hook 16, and then the hook 16 can be removed from the hanging ring 17. By setting the silicone 5, the outer wall of the hook 16 has an additional protective layer, which reduces the direct contact between the hook 16 and the hanging ring 17 during frequent insertion and removal of the hook 16, reduces the wear on the end of the hook 16, and extends the service life of the hook 16.By setting the sealing strip 6, when the protective cover 12 seals and protects the cutter head assembly 13, the sealing strip 6 can fill and seal the connection between the protective cover 12 and the cigarette machine housing 1, thereby improving the sealing performance of the protective cover 12 during protection. It can also reduce direct contact and wear between the protective cover 12 and the cigarette machine housing 1 caused by processing errors.
