[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0025] For example, see Figure 1 , Figure 1 This is a structural diagram of the optimal embodiment of the sinker structure of the utility model knitting jacquard machine. Figure 1As shown, in order to allow the worn needle cylinder to continue to be used and produce high-quality fabrics, at least one embodiment provides a knitting jacquard machine sinker structure, including: a ground yarn sinker 1 and a wool yarn sinker 2; wherein a thickened portion 11 is provided on one or both sides of the ground yarn sinker 1; and a line pressing area 21 is provided on the wool yarn sinker 2, and a heightened portion 22 is provided at one end of the line pressing area 21. After the ground yarn sinker 1 is thickened, the shaking of the ground yarn sinker 1 in the existing worn needle cylinder can be reduced. Specifically, the thickness of the ground yarn sinker 1 is 0.25mm. The thickness of the thickened portion 11 is 0.05mm. After the wool yarn sinker 2 is heightened, the uneven coil caused by the wear of the needle groove is avoided, and the height of the heightened portion 22 is 0.2mm. Therefore, the heightening and thickening of the sinker structure can improve the quality of the product jacquard machine, extend the service life of the needle cylinder, reduce the cost of replacing spare parts in the workshop, and reduce the generation of defective products. In addition, at least one assembly opening 3 is provided on the yarn sinker 2 .
[0026] For example 2, please refer to Figure 1 .like Figure 1 As shown, in order to allow the worn needle cylinder to continue to be used and produce high-quality fabrics, at least one embodiment provides a knitting jacquard machine sinker structure, including: a ground yarn sinker 1 and a wool yarn sinker 2; wherein a thickened portion 11 is provided on one or both sides of the ground yarn sinker 1; and a line pressing area 21 is provided on the wool yarn sinker 2, and a heightened portion 22 is provided at one end of the line pressing area 21. After the ground yarn sinker 1 is thickened, the shaking of the ground yarn sinker 1 in the existing worn needle cylinder can be reduced. Specifically, the thickness of the ground yarn sinker 1 is 0.25mm. The thickness of the thickened portion 11 is 0.05mm. After the wool yarn sinker 2 is heightened, the uneven coil caused by the wear of the needle groove is avoided, and the height of the heightened portion 22 is 0.2mm. Therefore, the heightening and thickening of the sinker structure can improve the quality of the product jacquard machine, extend the service life of the needle cylinder, reduce the cost of replacing spare parts in the workshop, and reduce the generation of defective products. In addition, at least one assembly opening 3 is provided on the yarn sinker 2 .
[0027] Please continue reading Figure 1 Combined with Figures 2 to 4 , Figure 2 A cross-sectional view of the preferred embodiment of the wool yarn sinker of the utility model; Figure 3 For this utility model Figure 2 The enlarged structural diagram at A in the middle; Figure 4 FIG. 2 is a cross-sectional view of the best embodiment of the convex ring of the utility model. Figures 1 to 4As shown, the inner wall of the assembly port 3 is provided with an oil storage structure 4. The oil storage structure 4 includes two convex rings 41; wherein the convex ring 41 is integrally arranged on the inner wall of the assembly port. The end of the convex ring 41 away from the assembly port 3 is an arc surface 43; wherein the convex ring 41 is coiled against the assembly part through the arc surface 43. Compared with the existing related technologies, the linear offset reduces the assembly contact area, thereby greatly reducing wear. In addition, a relative sealing effect is achieved between the two closed annular coils, so that a cavity that will not leak is formed in the middle of the assembly surface to hold the lubricating oil. Specifically, in order to further enhance the Sun Hua effect, a plurality of pits 42 are provided on the inner wall of the assembly port 3 between the two convex rings 41. The pit 42 is circular or polygonal in vertical section. The pit 42 can store lubricating oil before assembly, and the lubricating oil stored inside can act on the assembly surface to achieve a lubricating effect after use.
[0028] To sum up, after the ground yarn sedimentation plate 1 is thickened, the shaking of the ground yarn sedimentation plate 1 in the existing worn syringe can be reduced; after the wool yarn sedimentation plate 2 is heightened, the coil imbalance caused by the wear of the needle groove can be avoided, the quality of the product is improved, the service life of the syringe is extended, the cost of replacing spare parts in the workshop is reduced, and the generation of defective products is reduced; in addition, an oil storage structure 4 is provided on the inner wall of the assembly port 3 to reduce the assembly contact area, reduce wear, and at the same time improve the oil storage effect and reduce the probability of wear.
