Technical Field

[0001] The utility model relates to the technical field of circular knitting machine accessories, in particular to a double wear-resistant ring structure for a circular knitting machine needle cylinder. Background Art

[0002] Circular knitting machine cylinders are core components of circular weft and hosiery knitting machines. They play a vital role in the knitting industry. Their high-quality manufacturing processes and technical specifications ensure stable operation and efficient production. Circular knitting machine cylinders are typically made of high-grade steel and undergo multiple grinding and polishing processes.

[0003] The circular knitting machine needle cylinder is cylindrical, and its outer circumference and the outside of the top surface are evenly provided with sliding grooves for accommodating knitting needles and sinkers. During long-term operation, under the traction of the fabric, the knitting needles and sinkers will respectively wear the outer wall and top wall of the circular knitting machine needle cylinder, thereby causing defective marks on the surface of the fabric.

[0015] (3) Beneficial effects

[0016] The utility model provides a double wear-resistant ring structure for a circular knitting machine needle cylinder. It has the following beneficial effects:

[0017] 1. In the present invention, two wear-resistant sheets are installed on the upper side and outer side wall of the needle cylinder body respectively, which can prevent the knitting needles and sinker from directly contacting the needle cylinder body, thereby avoiding wear on the needle cylinder body and affecting the quality of the knitted fabric.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] The embodiment of the utility model provides a double wear-resistant ring structure for a circular knitting machine needle cylinder.

[0026] like Figure 1-3 As shown, it includes a needle cylinder body 1, a knitting needle 2 and a sinker 3, and is characterized in that: a sinker groove for accommodating the sinker 3 is provided on the outer side of the top wall of the needle cylinder body 1, an accommodating ring groove is opened on the inner side of the top wall of the needle cylinder body 1, the inner end of the sinker groove extends to the outer edge of the accommodating ring groove, an upper wear-resistant sheet 4 is bonded in the accommodating ring groove, and the accommodating ring groove is arranged at a position without a sinker groove, which can facilitate the grinding of the upper wear-resistant sheet 4 so that the upper wear-resistant sheet 4 remains horizontal, the upper side of the upper wear-resistant sheet 4 protrudes from the top wall of the needle cylinder body 1, and the sinker 3 is overlapped on the upper side of the upper wear-resistant sheet 4;

[0027] A sliding needle groove for accommodating the knitting needle 2 is provided on the lower side of the outer wall of the needle cylinder body 1, and a side ring groove is provided on the lower side of the outer wall of the needle cylinder body 1. A side wear-resistant plate 5 is bonded in the side ring groove, and the lower end of the sliding needle groove extends to the upper edge of the side ring groove. The side ring groove is provided at a position where there is no shear groove, which can facilitate the grinding of the side wear-resistant plate 5 and keep the outer edge of the side wear-resistant plate 5 in a flat state. The side wear-resistant plate 5 protrudes out of the side wall of the needle cylinder body 1, and the knitting needle 2 is overlapped on the outside of the side wear-resistant plate 5.

[0028] Example 1:

[0029] like Figure 3 As shown, the side wear-resistant plate 5 includes several side wear-resistant monomers 51 spliced end to end, and the end faces of two adjacent side wear-resistant monomers 51 are spliced obliquely to each other, and the outer side surfaces of the obliquely spliced side wear-resistant monomers 51 form an oblique seam, and the oblique seam is set at an angle to the extension direction of the sliding needle groove.

[0030] It is further configured that the upper wear-resistant plate 4 includes several upper wear-resistant units spliced end to end, the end faces of two adjacent upper wear-resistant units are obliquely spliced to each other, and an oblique seam is formed between the upper side surfaces of the obliquely spliced upper wear-resistant units, and the oblique seam is set at an angle to the extension direction of the Sinker groove.

[0031] It is further configured that the oblique seam is configured as any one of an inclined straight edge, a wave shape, and an arc shape, and is not parallel to the extension of the sinker groove.

[0032] Through the above technical solution, by setting the structural oblique surfaces of the upper wear-resistant plate 4 and the upper wear-resistant plate 4, the requirement that the splicing seam will not affect the normal operation of the circular knitting machine can be met through simple oblique surface processing, thereby reducing the difficulty of splicing the staggered arrangement of multiple layers of wear-resistant plates and improving the inlaying of wear-resistant plates.

[0033] Example 2:

[0034] like Figure 4 As shown, the two ends of the upper wear-resistant monomer and the side wear-resistant monomer 51 are respectively set as splicing ends and splicing notches 6 that match the splicing ends in a concave-convex manner. The splicing ends include a docking block 7 set on the outer edge of the upper side. The docking block 7 is a triangular pyramid. The upper side and the outer side of the docking block 7 are both set as inclined edges. The splicing notches 6 are provided with docking grooves that match the docking block 7 in a concave-convex manner. The docking block 7 and the docking groove form an oblique seam on the outer edge and the upper side of the upper wear-resistant monomer and the side wear-resistant monomer 51. The oblique seams on the outer edge and the upper side are respectively clamped with the sinker groove and the slide needle groove. Angle setting, the splicing end includes a positioning strip 8 provided on the lower outer edge, the cross-section of the positioning strip 8 is L-shaped, and the splicing notch 6 is provided with a positioning groove that matches the positioning sleeve. The positioning strip 8 on the splicing end forms a mortise and tenon structure with the docking block 7 and the splicing notch 6, which are respectively spliced and riveted on the inner and outer sides of the splicing notch 6 to form a splicing positioning for the spliced upper wear-resistant monomer and the side wear-resistant monomer 51, which facilitates the position alignment of the upper wear-resistant monomer and the side wear-resistant monomer 51, and the wear-resistant requirements of the upper side sinker 3 and the vertical knitting needle 2 can be met by the wear-resistant sheet of the same structure.
