Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a wear-resistant plastic heddle yarn. Background Technology

[0002] Heddle wires are important accessories in looms, usually made of steel wire, steel sheet, or plastic. They have a heddle eye in the center through which the warp yarn passes, and each heddle wire controls one warp yarn. During the weaving process, the heddle wire moves the warp yarn up and down, thus forming the shed, which facilitates the introduction of the weft yarn.

[0003] Compared to steel heddles and steel wire heddles, plastic heddles offer the advantage of significantly reducing the overall load on the loom. This not only improves operational flexibility but also reduces equipment wear. Furthermore, the relatively low production cost of plastic materials makes plastic heddles more economical for large-scale applications. At the same time, plastic heddles are rust-resistant, suitable for humid or chemically rich environments, and can effectively extend their service life. Therefore, they are widely used in the current weaving industry.

[0004] However, due to the low hardness of plastic heddles, the heddle holes are easily worn down by the friction of the warp yarns during use, forming deep grooves. This causes the warp yarns to get stuck when passing through the heddle holes, affecting the smoothness of weaving. If severely worn heddles are not replaced in time, it may lead to problems such as warp yarn breakage or a decline in fabric quality. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant plastic heddle wire to solve the problems in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A wear-resistant plastic heddle wire, comprising:

[0008] A plastic heddle eye includes a heddle frame and a heddle hole defined by the heddle frame;

[0009] A support body is disposed inside the plastic heddle eye, the hardness of the support body is greater than the hardness of the plastic heddle eye, and the support body includes a main body and a through hole formed on the main body;

[0010] Along the axial direction of the heald hole, the projection of the through hole covers the projection of the heald hole, and at least a portion of the projection outline of the through hole coincides with the projection outline of the heald hole.

[0011] In some embodiments, the orthographic projection of the through hole coincides with the orthographic projection of the heddle hole along its axial direction.

[0012] In some embodiments, the plastic heddle eye has a flat structure, including two opposing horizontal surfaces and a side edge surface connecting the two horizontal surfaces, and the heddle hole penetrates the two horizontal surfaces;

[0013] Along the axial direction of the heddle hole, the outer edge projection contour of the support is parallel to the outer edge projection contour of the side surface.

[0014] In some embodiments, the support is an insert injection molded part, and the thickness of the support is less than the thickness of the plastic eyelet.

[0015] In some embodiments, the support body is provided with a reinforcing structure to improve the bonding force with the plastic eyelet.

[0016] In some embodiments, the reinforcing structure is a through-hole that penetrates the support body;

[0017] Alternatively, the reinforcing structure may be at least one recess formed on the support.

[0018] In some embodiments, the width of the plastic heddle gradually decreases from the middle to the ends along its length.

[0019] In some embodiments, along the axial direction of the heald hole, the outer edge projection contour of the side surface includes two symmetrically arranged edge lines. Each edge line includes a straight line segment and a curved segment with non-zero curvature that is symmetrically connected to both ends of the straight line segment. The length of the straight line segment is greater than the length of the heald hole, and the length of the heald hole is 4mm to 5mm.

[0020] In some embodiments, the device further includes two plastic rods integrally formed at both ends of the plastic heddle along its length. The plastic rods are cylindrical in shape and have a diameter of 1 mm to 2 mm.

[0021] In some embodiments, a spring connecting section is provided on the free end of one of the plastic rods, and the spring connecting section is provided with connecting threads;

[0022] Another plastic rod has a wire connecting section on its free end. The wire connecting section has a wire connecting hole. Along the length of the plastic heddle, the wire connecting hole extends away from the plastic heddle to form a wire fixing hole. The connection between the wire connecting hole and the wire fixing hole protrudes inward to form a narrow channel.

[0023] In some embodiments, the support is made of heat-treated steel or heat-treated stainless iron.

[0024] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0025] This application relates to a wear-resistant plastic heddle wire, which enhances its wear resistance by incorporating a high-hardness support within the heddle eye. Axially, the projection of the support's through-hole overlaps the projection of the heddle eye, and at least a portion of the through-hole's projection outline coincides with the heddle eye's projection outline. This means that at least a portion of the support protrudes through the heddle frame and is flush with the surface of the heddle eye; in other words, the surface of the heddle eye is defined by both the heddle frame and the exposed support's through-hole surface.

[0026] During the weaving process, the warp yarns, supported by the through-holes of the support structure, can pass through the heddle holes more stably, preventing deep grooves from forming on the heddle hole surface due to long-term friction, thus extending the service life of the heddle yarns. At the same time, this design can effectively reduce the jamming phenomenon that occurs when the warp yarns pass through the heddle holes, improve the smoothness of weaving, reduce the warp yarn breakage rate, and ultimately improve the quality of the fabric.

[0027] Furthermore, since the support is placed inside the plastic heddle eye, it not only reduces warp damage or plastic heddle eye damage caused by friction between the heddle eye surface and the warp yarn, but also preserves the corrosion resistance of the plastic heddle eye, thereby further improving weaving efficiency and quality.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Please see Figures 1 to 4 One embodiment of this application provides a wear-resistant plastic heddle wire including a plastic heddle eye 1 and a support 2 disposed within the plastic heddle eye 1. The plastic heddle eye 1 includes a heddle frame 11 and a heddle hole 12 defined by the heddle frame 11.

[0042] The support body 2 has a higher hardness than the plastic heddle eye 1. The support body 2 includes a main body 21 and a through hole 22 formed on the main body 21. Axially, the projection of the through hole 22 overlaps the projection of the heddle hole 12, and at least a portion of the projection outline of the through hole 22 coincides with the projection outline of the heddle hole 12. That is, at least a portion of the surface of the through hole 22 is exposed and flush with the surface of the heddle hole 12. In other words, the surface of the heddle hole 12 is defined by both the heddle frame 11 and the exposed surface of the through hole 22.

[0043] In this embodiment, the orthographic projection of the through hole 22 coincides with the orthographic projection of the heald hole 12 along its axial direction. This reduces the difficulty and cost of fabrication.

[0044] In some embodiments, the support 2 is an insert injection molded part, and the thickness of the support 2 is less than the thickness of the plastic heddle 1. It should be noted that an insert injection molded part refers to a composite structure formed by pre-placing a material, such as metal, plastic, or other composite material, into a mold during the injection molding process, and then injecting molten plastic material into the mold to surround or combine the insert. This simplifies the preparation of the wear-resistant plastic heddle wire of this application and reduces the manufacturing cost. This is a conventional process and will not be elaborated upon here.

[0045] In some preferred embodiments, the support 2 is made of heat-treated steel or heat-treated stainless iron. This material is not easily deformed and has high stability. Of course, in other embodiments, the support 2 may also be made of alloy steel, stainless steel, or ceramic; this application does not limit this.

[0046] In some embodiments, the support body is provided with a reinforcing structure to improve the bonding force with the plastic eyelet.

[0047] In one embodiment, the reinforcing structure is a through-hole 10 penetrating the support, such as... Figure 3 As shown.

[0048] In another embodiment, the reinforcing structure is at least one recess 20 formed on the support, such as... Figure 4 As shown.

[0049] By incorporating a reinforcing structure, the contact area with the plastic heddle is increased during the injection molding process. This application does not specifically limit the shape or location of the through-hole or recess.

[0050] In some embodiments, the plastic heald eye 1 has a flat structure, including two opposing horizontal surfaces 111 and a side edge surface 112 connecting the two horizontal surfaces 111, with the heald hole 12 penetrating both horizontal surfaces 111. Axially, the outer edge projection contour of the support body 2 is parallel to the outer edge projection contour of the side edge surface 112. This reduces the space occupied during assembly in the loom. Furthermore, positioning the support body 2 in the middle of the plastic heald eye reduces local stress concentration, thereby improving the overall structural stability.

[0051] In some embodiments, the width of the plastic eyelet 1 gradually decreases from the middle to both ends along its length.

[0052] In detail, along the axial direction of the heald hole 12, the outer edge projection contour of the side edge surface 112 includes two symmetrically arranged edge lines. Each edge line includes a straight line segment and a curved segment with non-zero curvature symmetrically connected to both ends of the straight line segment. The length of the straight line segment is greater than the length of the heald hole 12. In this embodiment, the length of the heald hole is 4mm to 5mm. This application does not specifically limit the length and width of the heald hole, and they can be adjusted according to design requirements.

[0053] In this embodiment, the wear-resistant plastic heddle wire also includes two plastic rods 3 integrally formed at both ends of the plastic heddle eye 1 along its length. The plastic rods 3 have a cylindrical structure and a diameter of 1mm to 2mm. This application does not limit the diameter and length of the plastic rods and can adjust them according to design requirements. As can be seen from the above, setting the plastic heddle eye 1 to a spindle-shaped structure facilitates the transition connection between it and the plastic rods 3, improving aesthetics.

[0054] In detail, one of the plastic rods 3 has a spring connecting section 4 at its free end, and the spring connecting section 4 has a connecting thread 5. The other plastic rod 3 has a through-wire connecting section 6 at its free end, and the through-wire connecting section 6 has a wire connecting hole 7. Along the length of the plastic heddle 1, the wire connecting hole 7 extends away from the plastic heddle 1 to form a wire fixing hole 8. The connection between the wire connecting hole 7 and the wire fixing hole 8 protrudes inward to form a narrow channel. This is a conventional structure.

[0055] It is worth noting that in this embodiment, the through wire connecting section 6, the spring connecting section 4, the two plastic rods 3, and the plastic eyelet 1 are integrally injection molded.

[0056] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0057] This application relates to a wear-resistant plastic heddle wire, which enhances its wear resistance by incorporating a high-hardness support within the heddle eye. Axially, the projection of the support's through-hole overlaps the projection of the heddle eye, and at least a portion of the through-hole's projection outline coincides with the heddle eye's projection outline. This means that at least a portion of the support protrudes through the heddle frame and is flush with the surface of the heddle eye; in other words, the surface of the heddle eye is defined by both the heddle frame and the exposed support's through-hole surface.

[0058] During the weaving process, the warp yarns, supported by the through-holes of the support structure, can pass through the heddle holes more stably, preventing deep grooves from forming on the heddle hole surface due to long-term friction, thus extending the service life of the heddle yarns. At the same time, this design can effectively reduce the jamming phenomenon that occurs when the warp yarns pass through the heddle holes, improve the smoothness of weaving, reduce the warp yarn breakage rate, and ultimately improve the quality of the fabric.

[0059] Furthermore, since the support is placed inside the plastic heddle eye, it not only reduces warp damage or plastic heddle eye damage caused by friction between the heddle eye surface and the warp yarn, but also preserves the corrosion resistance of the plastic heddle eye, thereby further improving weaving efficiency and quality.

[0060] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
