Description

Technical Field

[0001] The utility model relates to the technical field of textile accessories, and more specifically, to a spiral groove cotton feeding roller. Background Art

[0002] Textile accessories include cotton roll rollers, feeding rollers and drafting rollers; rollers are divided into straight rollers and spinning cone rollers, which are shaped like a cylindrical shaft with strip grooves on the surface. Their function is to loosen and mix the fibers to form a uniform mat layer and then feed it into the carding machine to ensure continuous and uniform cotton supply to the carding machine and realize the continuity of the cleaning and carding process.

[0003] Patent application publication number: CN212025520U A cotton feeding roller assembly, a cotton feeding device and cotton processing equipment. Because the length-to-diameter ratio of the cotton feeding roller used in the machine is greater than, when the cotton feeding roller is subjected to local overload impact, the presence of the supporting core shaft can effectively help the cotton feeding roller body share the local overload impact, reduce the bending degree of the cotton feeding roller, and extend the service life of the cotton feeding roller. The shaft head, shaft body, and core shaft are assembled by the press-in method, and the contact position between the shaft head and the shaft body is welded to increase the overall tightness and avoid shaft breakage; the connection between the two end surfaces of the core shaft and the shaft head is welded to consolidate them into one.

[0004] However, when this structure is actually used, when the cotton feeding roller is subjected to overload impact, it will produce large vibrations. Only the supporting core shaft can share the local overload impact, and there is still large vibration as a whole. In addition, the pressure on the cotton feeding roller is insufficient, so its grip on the cotton layer is too small. Then, the fibers will be caught in blocks or large bundles before they are fully combed by the reel, and the desired combing and impurity removal effect cannot be achieved, which also reduces the textile quality.

One end of the two connecting strips 10 is movably connected to the top plate 5 and the bottom plate 6, and is transmitted to the supporting leg 4 through the lower fixing ring 3, and then transmitted to the top plate 5 through the supporting leg 4. The elastic effect generated by the expansion and contraction and reset of the spring 8 driven by the connecting strip 10 achieves a buffering effect, thereby reducing the shock absorption effect of the roller body 1 during operation and meeting people's demand for flexible support of the roller body 1.

[0027] Reference Figure 2 As shown, two fixing blocks 11 are arranged on the top of the lower fixing ring 3, and the surfaces of the two fixing blocks 11 are both provided with a first threaded hole 12, and the surface of the upper fixing ring is provided with a connecting groove 13, and the interior of the connecting groove 13 is provided with a second threaded hole 14, and the interiors of the first threaded hole 12 and the second threaded hole 14 are movably connected with fixing bolts 15, and the upper fixing ring is inserted into the lower fixing ring 3 from top to bottom, so that the fixing block 11 is inserted into the connecting groove 13, and then the fixing bolt 15 is aligned with the second threaded hole 14, and then the fixing bolt 15 is rotated clockwise to enter the second bolt and then continue to rotate, so that the fixing bolt 15 completely passes through the first threaded hole 12, so that the upper fixing ring and the lower fixing ring 3 are installed and fixed.
