Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to a durable heald. Background Art

[0002] Heald is one of the accessories of the loom. It is made of thread, steel wire or steel sheet, and has a small hole (heald eye) in the middle for the warp yarn to pass through. Each heald controls a warp yarn. During weaving, it drives the warp yarn to move up and down to form a shed, which is convenient for introducing the weft yarn. The existing heald has a flat elliptical heald eye in the middle of the steel wire, and the two ends of the heald eye are rotated and twisted to form a force-bearing part. This kind of steel wire is mainly used for weaving on rapier looms. However, when producing high-denier products of 50000-90000D, this kind of heald is very easy to break due to friction with the heald frame, and because the heald eye often rubs against the warp yarn, the heald eye will be deformed, affecting its use, and it is very easy to make the warp yarn rough, seriously affecting the product quality. Utility Model Content

[0003] The utility model aims to provide a durable heald, which increases the strength, avoids the breakage caused by friction with the heald frame, and prevents deformation from affecting the use.

[0004] The technical solution adopted by the utility model is a durable heald, comprising a heald main body, a spindle-shaped connecting part is provided in the middle of the heald main body, a heald eye is provided in the center of the connecting part, the heald eye is circular, and is made of stainless steel wire with uniform diameter, the outer walls at the left and right ends of the heald eye are connected to the inner walls at the left and right ends of the connecting part, and the connecting part is divided into an upper through groove and a lower through groove.

[0005] Preferably, a flat sealing piece is arranged in the upper through groove and the lower through groove, and the sealing piece is cast by plastic.

[0006] Preferably, the upper through groove and the lower through groove are symmetrical about the center of the heddle eye.

[0007] Preferably, the connecting portion has a length of 18 mm and a width of 10 mm.

[0008] Preferably, the diameter of the above-mentioned heddle eyelet is 8 mm.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: by improving the heald eyelet and the external structure of the heald eyelet, a circular heald eyelet is adopted, the outside of the heald eyelet is surrounded by a spindle-shaped connecting part, and the connecting part and the heald eyelet are connected by a sealing piece, thereby improving the strength of the heald and the bearing capacity of the yarn, solving the problem that the heald is very easy to break due to friction with the heald frame and the heald eyelet is deformed when producing high-denier products of 50000-90000D, reducing the yarn breakage rate and defect rate, and improving product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the structure of the utility model;

[0011] Markings in the figure: 1, heald body, 2, connecting part, 21, upper through groove, 22, lower through groove, 3, heald eye, 4, sealing piece. DETAILED DESCRIPTION

[0012] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0013] Example 1

[0014] like Figure 1 As shown, a durable heald comprises a heald body 1, a spindle-shaped connecting part 2 is provided in the middle of the heald body 1, a heald eye 3 is provided in the center of the connecting part 2, the heald eye 3 is circular, and is made of stainless steel wire with uniform diameter, which is the same as the skeleton of the connecting part 2, and the diameter of the heald eye 3 is 8 mm. The outer walls at the left and right ends of the heald eye 3 are connected to the inner walls at the left and right ends of the connecting part 2, dividing the connecting part 2 into an upper through groove 21 and a lower through groove 22.

[0015] Furthermore, the connecting portion 2 is centrally symmetrical, with a length of 18 mm and a width of 10 mm. The upper through groove 21 and the lower through groove 22 are centrally symmetrical about the center of the circle of the heddle eye 3. A planar sealing piece 4 is arranged in the upper through groove 21 and the lower through groove 22, and the sealing piece 4 is cast by plastic.

[0016] The heald eye 3 is designed to be circular with a diameter of 8 mm, which is conducive to weaving of high-denier yarn of 50000-90000D after warping. The outside of the heald eye 3 is surrounded by a spindle-shaped connecting part 2, and the outer wall of the heald eye 3 is connected to the inner wall of the connecting part 2. The connecting part 2 has a good supporting effect on the heald eye 2, and the heald eye 3 divides the connecting part into an upper through groove 21 and a lower through groove 22 similar to a triangular shape. Both the upper through groove 21 and the lower through groove 22 are provided with sealing sheets, which improve the support and strengthening effect on the heald eye 3. The heald wire body 1 at the heald wire 3 has high strength and bearing capacity for yarn stress, which effectively solves the problem that the heald wire is easily broken by friction with the heald frame, prevents the heald wire from deforming, reduces the yarn breakage rate and defect rate, and improves product quality.

[0017] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
