Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco machinery technology, specifically to a titanium-copper chain for a tobacco shredder. Background Technology
[0002] The copper busbar chain of a tobacco shredder is used to transport tobacco leaves. Its surface grooves increase friction. However, traditional copper busbar chains are prone to water accumulation in the through-holes after cleaning, leading to copper rust and contamination of the tobacco leaves. Although existing technology incorporates guide grooves on the underside of the through-holes, the following drawbacks still exist:
[0003] 1. Single-point drainage is inefficient and easily clogged by soot.
[0004] 2. Stress concentration occurs at the connection between the connecting post and the chain body, making it prone to breakage after long-term use;
[0005] 3. Insufficient rust resistance on the surface of copper materials;
[0006] 4. The entire groove needs to be replaced after it wears down, resulting in high maintenance costs. Utility Model Content
[0007] To address the aforementioned problems, this invention provides a titanium-copper chain for a tobacco shredder, which solves the issues of poor drainage, easy corrosion, and insufficient mechanical strength through structural optimization.
[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a titanium-copper chain for a tobacco shredder, comprising a long strip-shaped chain body, connecting posts on both sides of the long strip-shaped chain body, through holes for pin shafts to pass through on the connecting posts, the length direction of the through holes being parallel to the length direction of the long strip-shaped chain body, a groove on the upper surface of the long strip-shaped chain body, an inclined guide groove on the lower side wall of the through holes, the inclined guide groove extending along the length direction of the through holes as a continuous groove, drainage micro-holes penetrating the connecting posts being provided at the bottom of the groove, a titanium-coated anti-rust layer being laminated on the surface of the chain body, and a wear-resistant ceramic strip being embedded in the groove.
[0009] As an improvement, a triangular reinforcing rib is provided at the base of the connecting column.
[0010] As an improvement, the diameter of the drainage micropores is 0.3-0.8 mm, and they are evenly distributed at the bottom of the inclined guide channel.
[0011] As an improvement, the height of the triangular reinforcing rib is 1 / 4 to 1 / 3 of the height of the connecting column, and the material is the same as that of the long strip chain.
[0012] As an improvement, a dovetail groove structure is provided between the wear-resistant ceramic strip and the groove, and the wear-resistant ceramic strip is embedded in the groove through the dovetail groove structure.
[0013] The advantages of this utility model compared with the prior art are as follows:
[0014] 1. Enhanced drainage structure: The inclined guide channel extends into a continuous groove along the length of the through hole, and drainage micro-holes are added to the bottom of the channel to form a "channel + hole" dual-channel drainage.
[0015] 2. Improved mechanical strength: Triangular reinforcing ribs are installed at the base of the connecting column to distribute stress.
[0016] 3. Optimized rust prevention performance: The chain surface is coated with a titanium anti-rust layer.
[0017] 4. Enhanced wear resistance: Wear-resistant ceramic strips are embedded in the grooves and can be replaced individually. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] Combined with appendix Figure 1 and attached Figure 3 :
[0027] A titanium-copper chain for a tobacco shredder includes a long strip chain 1, with connecting posts 2 on both sides of the long strip chain 1. A triangular reinforcing rib 9 is provided at the base of the connecting post 2. The height of the triangular reinforcing rib 9 is 1 / 4 to 1 / 3 of the height of the connecting post 2, and the material is the same as that of the long strip chain 1.
[0028] Through this structure, the triangular reinforcing rib 9 can effectively disperse the stress at the root of the connecting column 2, significantly reducing the risk of fracture caused by long-term use and improving the overall structural strength and service life.
[0029] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5 and attached Figure 6 :
[0030] The connecting post 2 has a through hole 3 for the pin shaft to pass through. The length direction of the through hole 3 is parallel to the length direction of the long strip chain 1. The upper surface of the long strip chain 1 is provided with a groove 4. An inclined guide groove 5 is provided on the lower side wall of the through hole 3. The inclined guide groove 5 extends along the length direction of the through hole 3 into a continuous groove. The bottom of the groove is provided with drainage micro-holes 6 that penetrate the connecting post 2. The diameter of the drainage micro-holes 6 is 0.3-0.8mm, and they are evenly distributed at the bottom of the inclined guide groove 5.
[0031] Through this structure, the inclined guiding channel 5 with continuous groove design and the evenly distributed drainage micro-holes 6 form a dual-channel drainage system: the continuous groove guides the water flow to gather quickly, while the micro-holes with a diameter of 0.3-0.8mm efficiently discharge the accumulated water, completely solving the problems of easy clogging and low efficiency of traditional single-point drainage.
[0032] Combined with appendix Figure 2 and attached Figure 4 :
[0033] The surface of the elongated chain 1 is coated with a titanium anti-rust layer, and a wear-resistant ceramic strip 8 is embedded in the groove 4. A dovetail groove structure 7 is provided between the wear-resistant ceramic strip 8 and the groove 4, and the wear-resistant ceramic strip 8 is embedded in the groove 4 through the dovetail groove structure 7.
[0034] Through this structure, the titanium anti-rust layer inhibits the corrosion of the surface of the long chain 1 from the source, avoiding contamination of the tobacco leaves; the wear-resistant ceramic strip 8 embedded in the dovetail groove structure 7 greatly improves the wear resistance of the groove 4, and can be replaced independently after wear, greatly reducing maintenance costs.
[0035] In specific implementation of this utility model, when the chain is cleaned or encounters water, the liquid quickly gathers along the inclined guide channel 5 on the lower side of the through hole 3, and is discharged bidirectionally through the drainage micro-holes 6 evenly distributed at the bottom of the channel, thus avoiding water accumulation and blockage.
[0036] A triangular reinforcing rib 9 is cast integrally at the base of the connecting column 2, with a height of 1 / 4 to 1 / 3 of the height of the connecting column. The material is copper alloy, just like the long strip chain 1, which significantly disperses stress.
[0037] The surface of the long chain 1 is coated with a titanium anti-rust layer (titanium alloy coating) through electroplating process, covering all exposed copper substrates. The groove 4 is pre-machined with dovetail groove structure 7, and the wear-resistant ceramic strip 8 is slid into the dovetail groove for installation. After wear, only one strip needs to be removed and replaced.
[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
