[0022] 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.

[0023] The embodiment of the utility model provides a wear-resistant ring splicing structure for a circular knitting machine needle cylinder.

[0024] like Figure 1 、 2As shown, it includes a needle cylinder body 1, a knitting needle 2 and a sinker 3. The outer side of the top wall of the needle cylinder body 1 is provided with a sinker groove for accommodating the sinker 3, and the lower side of the outer wall of the needle cylinder body 1 is provided with a slide needle 2 groove for accommodating the knitting needle 2. The sinker 3 is slidably connected in the sinker groove, and the sinker 3 slides inside and outside the sinker groove. The knitting needle 2 is slidably connected in the slide needle 2 groove, and the knitting needle 2 slides up and down in the slide needle 2 groove. The inner side of the top wall of the needle cylinder body 1 is provided with an accommodating ring groove, and an upper wear-resistant sheet 4 is bonded in the accommodating ring groove. The upper wear-resistant sheet 4 The upper side protrudes from the top wall of the syringe body 1, and the sinker 3 is overlapped on the upper side of the upper wear-resistant sheet 4; a side ring groove is provided on the lower side of the outer wall of the syringe body 1, and a side wear-resistant sheet 5 is bonded in the measuring ring groove. The side wear-resistant sheet 5 protrudes out of the side wall of the syringe body 1, and the pointer 2 is overlapped on the outside of the side wear-resistant sheet 5. The knitting needle 2 and the sinker 3 are respectively overlapped on the side wear-resistant sheet 5 and the upper wear-resistant sheet 4, supporting the knitting needle 2 and the sinker 3 to be separated from the syringe body 1, avoiding direct contact between the knitting needle 2 and the sinker 3 and the syringe body 1, and protecting the surface of the syringe body 1 from wear.

[0025] like Figure 3 As shown, the upper wear-resistant plate 4 and the side wear-resistant plate 5 both include a number of wear-resistant monomers 6 spliced end to end, and the wear-resistant monomers 6 are made of wear-resistant ceramic or carbon fiber. The end faces of two adjacent wear-resistant monomers 6 are spliced obliquely to each other, and an oblique seam is formed between the upper side surfaces of the obliquely spliced wear-resistant monomers 6, and the oblique seam is set at an angle to the extension direction of the Sinker groove.

[0026] One end of the wear-resistant monomer 6 is polished with a docking block, and the docking block includes an integrally formed upper protrusion 7 and a lower protrusion 8. The outer side of the lower protrusion 8 protrudes from the outer side of the upper protrusion 7 in a step-like shape, and the outer ends of the upper protrusion 7 and the lower protrusion 8 are set as inclined planes. The other end of the wear-resistant monomer 6 is matched with the docking block, and the outer sides of the wear-resistant monomers 6 that are docked with each other will form a vertical splicing seam. The lower protrusion 8 is integrally formed with the wear-resistant monomer 6 and is sealed directly below the splicing seam. During the up and down movement of the knitting needle 2, even if the knitting needle 2 coincides with the vertical splicing seam, it will not be able to enter the vertical splicing seam due to the support of the lower protrusion 8, thereby avoiding the knitting needle 2 from being stuck in the vertical splicing wind and ensuring the normal operation of the circular knitting machine.

[0027] 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, which is not parallel to the extension of the sinker groove. As long as the oblique seam is not parallel to the extension direction of the sinker groove, the sinker piece 3 will not sink into the seam during the sliding of the sinker piece 3 in and out, so that the sinker piece 3 will not get stuck during the operation of the circular knitting machine, thereby ensuring the product quality of the woven fabric.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
