Description

Technical Field

[0001] This utility model relates to heddle eyes and combined jacquard heddle yarns, belonging to the technical field of heddle yarns for jacquard looms. Background Technology

[0002] The quality requirements for slender stainless steel jacquard heddles are a smooth finish. The heddle rod, which forms the base of the jacquard heddles, must first undergo calendering and perforation machining to obtain the ring frame structure. Then, the metal wire heddle loops used for yarn guidance are fitted into this ring frame and fixed by welding or bonding. However, welding or bonding has drawbacks: residues inevitably exist in batches, and the separate heddle loops and ring frame structure may have defects at the joint that hinder warp yarn sliding. In actual high-speed and / or high-tension weaving processes, warp yarns of different fineness experience long-term, intense friction with the heddle loops, and the warp yarns move up and down with the heddle loops, generating stress on the heddle loops. This makes it difficult to reliably fix the heddle loops over a long period. The heddle rod is usually made of two rods welded together, and residues inevitably remain on the welded rod, affecting the smoothness of the product. Utility Model Content

[0003] The purpose of this utility model is to provide a comprehensive eye to address the shortcomings of the existing technology.

[0004] Therefore, this utility model relates to a heddle eye, including two opposite end faces, a heddle eye hole penetrating the two end faces, and grooves respectively provided on the two end faces for accommodating the heddle screw.

[0005] The aforementioned end face is flat and has an upper hole that is spaced above the heddle eye hole for the upper heddle screw to pass through, and a lower hole that is spaced below the heddle eye hole for the lower heddle screw to pass through. The aforementioned groove has two upper grooves that communicate with the upper hole for securing the upper heddle screw, and two lower grooves that communicate with the lower hole for securing the lower heddle screw. The aforementioned upper grooves and lower grooves extend along the vertical axis.

[0006] The aforementioned eyelet has upper and lower pointed heads. The upper pointed head includes two upper side surfaces that form acute angles with each other, an upper arc surface that bridges the upper side surfaces, and upper groove bottom extension surfaces that extend from the bottom of the upper groove along the vertical axis and are opposite to each other. The lower pointed head includes two lower side surfaces that form acute angles with each other, a lower arc surface that bridges the lower side surfaces, and lower groove bottom extension surfaces that extend from the bottom of the lower groove along the vertical axis and are opposite to each other.

[0007] The aforementioned end face has an upper converging side that gradually approaches and connects to the upper side and a lower converging side that connects to the lower side, a main side that extends at least partially straight along the vertical axis and is opposite to each other, an upper inferior arc side that connects the main side and the upper converging side, and a lower inferior arc side that connects the main side and the lower converging side.

[0008] The aforementioned eye is made of zirconium oxide.

[0009] The aforementioned eyelets are manufactured through mixing, granulation and injection molding, sintering, and mirror polishing.

[0010] Another aspect of this utility model relates to a combined jacquard heddle, comprising an upper heddle rod, a lower heddle rod, and heddle eyelets as described above. The improvement is that the upper heddle rod and the lower heddle rod are each a single piece. The upper heddle rod is fitted with an upper hole and respectively locked in an upper groove, and the upper heddle rods are fixedly connected to each other. The lower heddle rod is fitted with a lower hole and respectively locked in a lower groove, and the lower heddle rods are fixedly connected to each other.

[0011] The upper heddle screws are connected by double strands twisted together, and each upper heddle screw abuts against the upper groove to form a locking connection. The groove depth of the upper groove is smaller than the diameter of the upper heddle screw. The lower heddle screws are also connected by double strands twisted together, and each lower heddle screw abuts against the lower groove to form a locking connection. The groove depth of the lower groove is smaller than the diameter of the lower heddle screw. The diameter of the circle containing the upper arc surface is smaller than the diameter of the upper heddle screw, and the diameter of the circle containing the lower arc surface is smaller than the diameter of the lower heddle screw.

[0012] The upper and lower heddle screws mentioned above are made of metal wire, with stainless steel wire being the preferred material.

[0013] The innovative heddle eye design provided by this utility model is a single part. The structure of the heddle eye hole and the groove can be integrally manufactured into this part, overcoming the shortcomings of existing technologies where heddle eye ring parts are welded or bonded separately, resulting in deformation or loosening and falling off from the ring frame of the heddle product, requiring replacement of the jacquard heddle. The groove design facilitates the reliable accommodation of the heddle rod during subsequent assembly, forming a combined jacquard heddle product. Furthermore, the upper and lower holes are respectively matched with corresponding upper and lower grooves (pairs), allowing the heddle eye of this utility model to form a combined jacquard heddle together with the upper and lower heddle rods. Moreover, the geometric design of this heddle eye effectively reduces the friction between the warp yarns and the adjacent jacquard heddle surfaces during the up-and-down movement of the heddle yarns as they pass through and move in the warp direction. This is particularly evident in the dense weaving of high warp density. In the case of jacquard heddles, the breakage rate can be reduced. The heddles made of zirconia are used in a forward-looking manner. They are highly tough, rust-resistant, and do not stick together. Under high-speed operation or high tension fluctuations, the zirconia heddles can withstand the high-frequency and severe friction of the warp yarns, and bear the stress of ultra-fine denier fibers, coarse yarns, or high-strength yarns. The zirconia heddles are extremely resistant to wear and cracking, have a long service life, and can be formed into upper and lower grooves and upper and lower holes in one step without machining. The heddles have a highly smooth outer edge and heddle hole wall. On the one hand, it can significantly reduce the frictional resistance between the warp yarns and the heddle hole wall, making the warp yarns, especially fine yarns or high-value-added yarns, less prone to pilling or breakage, improving weaving efficiency and fabric quality. On the other hand, during the opening movement, it is beneficial for multiple warp yarns adjacent to the heddles to slide with low resistance friction at the outer edge of the heddles.

[0014] From the upper (lower) connecting hole to the upper (lower) groove, until the bottom of the upper (lower) groove just connects to the extended surface of the bottom of the upper (lower) groove, the entire upper (lower) groove can fully and effectively accommodate the upper (lower) heddle rod. Furthermore, the upper (lower) heddle rod is in a twisted and wound state to overcome the rigidity of the folded heddle rod and is then clamped and locked in the aforementioned upper (lower) groove structure. This has been confirmed by final testing to achieve unexpected technical advantages in the locking performance of the upper (lower) heddle rod, and the assembly efficiency is high. When the diameter of the circle containing the upper (lower) arc surface of the heddle eye is smaller than the diameter of the corresponding upper (lower) heddle rod, it can effectively avoid snagging and multiple weaving defects caused by snagging during the warp lifting process in weaving.

[0022] like Figure 1 As shown, the heddle eye 1, a core component of the assembly P, is used in a jacquard loom. The jacquard loom includes a jacquard loom 7, the assembly P, and the loom itself. The assembly mainly consists of a guide rope 8, a heddle plate, a return spring 81, jacquard heddles connecting the guide rope and the return spring respectively, and a return heddle seat 82 (fixed to the ground) for the return spring to connect. The upper end of the jacquard heddle has a lifting lug, and the lower end has a molded connector (not shown). The upper ends of multiple guide ropes 8 are bundled and molded into quick-connect female parts, which are then inserted into the quick-connect male parts of the jacquard loom's needle assembly. The bundled guide ropes are threaded one by one into the heddle plate, which is placed horizontally above the jacquard heddle. The tail ends of each guide rope passing downwards through the heddle plate are attached to the lifting lug. The molded connector is threaded to the upper end of the return spring 81. The heddle plate has through holes arranged in a quincunx pattern for the guide ropes 8 to pass through. The arrangement has depth and width (i.e., jacquard heddles are arranged closely together in the longitudinal and transverse directions according to the process). Each jacquard heddle eye 1 is threaded with a warp 5L. The warp is withdrawn by the warp beam 91 belonging to the warp feeding mechanism of the loom and moves in the warp direction L. The fabric formed by the reed 92 of the weft insertion mechanism is controlled by the take-up mechanism and wound up on the take-up roller 93. The jacquard machine 7, which is coordinated with the loom movement, controls the opening stroke so that the warp 5L forms upper and lower layers for the weft 6W controlled by the weft insertion mechanism of the loom to interweave.

[0023] Please see Figures 2-4As shown, the heddle eye 1 is a flat, ceramic-based component, comprising two opposing end faces 1A and 1A', a heddle eye hole 10 penetrating the end faces 1A and 1A, and grooves on the end faces 1A and 1A respectively for accommodating the heddle screw. End faces 1A and 1A' refer to two faces extending along the weft direction W; the heddle eye hole 10, formed by passing through one end face to the other, is used for threading, guiding, and supporting the warp thread 5L.

[0024] The heald screws include the upper heald screw 4U and the lower heald screw 4D (see...). Figures 5-7 ),like Figure 2 As shown, compared to the periphery of the heddle eye, end faces 1A and 1A' are flat and ideally parallel to each other, serving as the basis for groove machining and stable locking of the heddle screw. End faces 1A and 1A' are perforated by an upper hole 12U located above the heddle eye hole 10 for the upper heddle screw to pass through, and a lower hole 12D located below the heddle eye hole 10 for the lower heddle screw to pass through. The grooves have upper grooves 11U and 11U' that communicate with the corresponding openings of the upper hole 12U for locking the upper heddle screw, and lower grooves 11D and 11D' that communicate with the corresponding openings of the lower hole 12D for locking the lower heddle screw. The upper grooves 11U and 11U' and the lower grooves 11D and 11D' extend along the vertical axis Z of the three-axis coordinate of the heddle eye.

[0025] The eye has an upper pointed head and a lower pointed head. The upper pointed head includes two upper side surfaces 23U that form acute angles with each other, an upper arc surface 3U that bridges the two upper side surfaces 23U, and upper groove bottom extension surfaces 11U-1 and 11U'-1 that extend from the bottom of the upper grooves 11U and 11U' along the vertical axis Z and are opposite to each other. The lower pointed head includes two lower side surfaces 23D that form acute angles with each other, a lower arc surface 3D that bridges the two lower side surfaces 23D, and lower groove bottom extension surfaces 11D-1 and 11D'-1 that extend from the bottom of the lower grooves 11D and 11D' along the vertical axis Z and are opposite to each other.

[0026] On both sides of end faces 1A and 1A', there are two upper converging sides 22U facing each other and gradually approaching the vertical axis Z, connecting the upper side face 23U and two lower converging sides 22D connecting the lower side face 23D; two main sides 2 extending at least partially straight along the vertical axis Z and facing away from each other; two upper minor arc sides 21U connecting the main sides 2 and the upper converging sides 22U respectively; and two lower minor arc sides 21D connecting the main sides 2 and the lower converging sides 22D respectively. Figure 2 The two main side surfaces 2 are preferably parallel to the vertical axis Z, and the central angles of the upper and lower minor arc side surfaces in the current case are approximately 15°. In order to keep the drawing clean, each pair of side surfaces on both sides of the end face and the side surfaces on both sides of the upper and lower pointed heads are numbered the same, and together with the upper and lower arc surfaces, they form a circumferentially closed single-piece part.

[0027] like Figure 4 As shown, the heddle eye 1 is made of zirconium oxide. In detail, the heddle eye is made by manufacturing a semi-finished product from zirconium oxide powder through intensive mixing, granulation and injection molding of the intensively mixed billet, and sintering, and the outer contour, heddle eye hole wall and hole opening of the semi-finished product are mirror polished to become the finished product.

[0028] The heddle eye 1 is manufactured using low-friction technology. The resulting semi-finished product is mirror-polished to achieve a highly smooth zirconia heddle eye component with a high-gloss finish on both the outer edge and the heddle eye hole. This reduces frictional resistance between the outer surface of the finished heddle eye and the warp yarns, making it suitable for warp yarns of various fineness and strength, and less prone to pilling and warp breakage. This heddle eye can withstand long-term, intense friction with the warp yarns on a jacquard loom under high speed or high tension fluctuations. Figure 5 , 6 The diagram shows that the warp thread passing through one heald eye is lifted and moved towards the upper shed position. During the lifting process, the warp thread rubs against the outer contour of the other heald eye (in the lowered state) with low frictional resistance and smoothly transitions to rub against the upper heald screw 4U with low frictional resistance. At the same time, the warp thread passing through the other heald eye is lowered by the restoring force of the heald return spring 81 and moves along the lower shed position. During the descent, the warp thread rubs against the outer contour of the aforementioned heald eye with low frictional resistance and smoothly transitions to rub against the lower heald screw 4D with low frictional resistance.

[0029] The heddles described in the above embodiments are in the field of jacquard loom assembly technology, that is, according to another aspect of this utility model, please refer to [link to relevant documentation]. Figures 5-7 As shown, a combined jacquard heddle system is provided, including an upper heddle rod 4U, a lower heddle rod 4D, and heddle eyelets 1 as described above. The upper heddle rod 4U and the lower heddle rod 4D are each a single piece. The upper heddle rod 4U passes through the upper hole 12U and is folded in half, respectively fitting into the upper grooves 11U and 11U'. The upper heddle rods are fixedly connected to each other. The groove widths of the upper grooves 11U and 11U' in the weft direction W are respectively adapted to the diameter d4U of the upper heddle rod 4U. The lower heddle rod 4D passes through the lower hole 12D and is folded in half, respectively fitting into the lower grooves 11D and 11D'. The lower heddle rods are fixedly connected to each other. The groove widths of the lower grooves 11D and 11D' in the weft direction W are respectively adapted to the diameter d4D of the lower heddle rod 4D. The fixed connection of the upper heddle rod 4U and the lower heddle rod 4D is not limited to welding (e.g., soldering) or bonding (e.g., epoxy bonding).

[0030] The upper heddle screw 4U is a double-stranded, intertwined connection, allowing it to abut against the upper grooves 11U and 11U' to form a locking engagement. The groove depths of the upper grooves 11U and 11U' in the warp direction L are smaller than the diameter d4U of the upper heddle screw 4U. The lower heddle screw 4D is also a double-stranded, intertwined connection, allowing it to abut against the lower grooves 11D and 11D' to form a locking engagement. The groove depths of the lower grooves 11D and 11D' in the warp direction L are smaller than the diameter d4D of the lower heddle screw 4D. Compared to bonding or welding the upper and lower heddle screws, the intertwined and tightly twisted connection of the upper heddle screws 4U and 4D does not produce any residue that affects their surface finish. Please refer to [link to relevant documentation]. Figure 7 and combined Figure 3 The diameter d3U of the circle containing the upper arc surface 3U is smaller than the diameter d4U of the upper heddle screw 4U, and the diameter d3D of the circle containing the lower arc surface 3D is smaller than the diameter d4D of the lower heddle screw 4D.

[0031] The upper heddle screw 4U and the lower heddle screw 4D are made of metal wire, preferably stainless steel wire, specifically stainless steel wire with a circular or near-circular cross section (such as an elliptical cross section). The cross sections of the upper heddle screw 4U and the lower heddle screw 4D are constant and equal, with an ideal diameter of 0.4 mm. The volume of the heddle eye 1 can be figuratively regarded as the size of approximately four grains of rice.

[0032] In the description of this utility model, it should be noted that the terms upper and lower holes, upper and lower grooves and their bottom extension surfaces, upper and lower converging sides, upper and lower inferior arc sides, upper and lower sides, upper and lower arc surfaces, etc., indicate the orientation based on the orientation shown in the accompanying drawings, and are only for ease of description, not to indicate or imply that the heddle eye must have a specific orientation or be constructed in a specific orientation, and therefore should not be construed as a limitation of this utility model. When the hole is closer to the threaded rope 8 of the device P and when the groove is closer to the threaded rope, then the hole is the upper hole and the groove is the upper groove; when the hole is closer to the heddle return spring 81 of the device P and when the groove is closer to the heddle return spring, then the hole is the lower hole and the groove is the lower groove. Based on this, the upper hole, upper groove and lower hole, lower groove of the heddle eye can be interchanged. Specifically, the lower hole is reversed to become the upper hole and passed through the upper heddle screw; the lower groove is reversed to become the upper groove and locked in place with the upper heddle screw. Similarly, the upper hole is reversed to become the lower hole and passed through the lower heddle screw; the upper groove is reversed to become the lower groove and locked in place with the lower heddle screw. The upper heddle screw can still be hooked to the through wire rope 8, and the lower heddle screw can also be threadedly connected to the return spring 81.
