Description

Technical Field

[0001] This invention belongs to the field of loom technology, and specifically relates to a warp and weft yarn binding device and binding method for double-sided mesh weaving. Background Technology

[0002] Mesh fabrics, due to their porous and lightweight structural characteristics, are widely used in various fields such as industry, agriculture, construction, and composite materials. The basic weaving structures of this type of fabric include single-sided weave and double-sided weave.

[0003] In traditional double-sided mesh fabrics, although both sides of the fabric are made of interwoven warp and weft yarns forming a mesh surface, there is a lack of stable connection between the warp and weft yarns of the upper and lower mesh fabrics. The integrity is maintained only by the friction between the yarns. This structural defect makes the fabric prone to relative slippage of yarns and loosening of the structure during actual stress, which seriously affects its dimensional stability and mechanical properties.

[0004] In existing technologies, while single-sided heddle devices can be used to enhance the binding effect between warp and weft yarns in single-sided mesh fabrics, their mechanism of action is limited to binding the yarns on only one side of the fabric. Since double-sided mesh fabrics require the simultaneous formation of two independent warp and weft yarn layers during weaving, single-sided heddle devices cannot apply effective binding to both surfaces simultaneously. Therefore, they are unsuitable for overall structural reinforcement of double-sided mesh fabrics, resulting in the inherent problem of deformation and loosening in such fabrics. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a warp and weft yarn binding device and method for double-sided mesh weaving, which enables synchronous and coordinated movement of multiple sets of binding yarns. This not only significantly improves the binding reliability and accuracy of the mesh warp and weft yarns but also optimizes the compactness of the mechanical structure, facilitating high-speed, stable, and efficient weaving production of large-pore double-sided meshes.

[0010] Preferably, the transverse linkage is a parallelogram connector, and one end of the transverse linkage is hinged to the frame, and the other end is hinged to the transverse lifting plate I or transverse lifting plate II.

[0011] A method for binding warp and weft yarns in double-sided mesh knitting, based on setting yarn movement parameters using a binding device, wherein binding yarn I passes through the guide needle of the transverse heald frame I and is led to the upper mesh surface of the fabric; binding yarn II passes through the guide needle of the transverse heald frame II and is led to the upper mesh surface of the fabric; binding yarn III passes through the guide needle of the transverse heald frame III and is led to the lower mesh surface of the fabric; binding yarn IV passes through the guide needle of the transverse heald frame IV and is led to the lower mesh surface of the fabric. The specific method for binding warp and weft yarns is as follows: Step 1, Upper Mesh Surface: Binding yarn I and binding yarn II move laterally above the upper warp yarn and intersect each other; Lower grid surface: Binding yarns III and IV move laterally below the lower warp yarns and intersect each other; Step 2: Upper mesh surface: After the transverse crossing, binding yarn I and binding yarn II descend simultaneously, and the upper warp yarn of the same reed eye forms the upper weave opening II; Lower mesh surface: After the transverse crossing, binding yarns III and IV rise simultaneously, and the lower warp yarn with the same reed eye forms the lower weave opening II; Step 3: Upper mesh surface: The upper weft yarn passes through the alternating upper weft openings I and II, wherein upper weft opening I is formed by the alternating arrangement of upper warp yarns; Lower mesh surface: The lower weft yarn passes through the alternately distributed lower weft openings I and II, wherein the lower weft opening I is formed by the alternating arrangement of lower warp yarns; The weft insertion operation is carried out synchronously by moving the reed; Step 4: Upper mesh surface: After the upper warp yarns move up and down alternately, binding yarn I and binding yarn II rise simultaneously above the upper warp yarns; Lower mesh surface: After the lower warp yarns move up and down alternately, binding yarn III and binding yarn IV descend simultaneously to below the lower warp yarns; Step 5: Upper mesh surface: Binding yarn I and binding yarn II move laterally in the opposite direction to the previous lateral movement above the upper warp yarn to achieve a new intersection; Lower grid surface: Binding yarns III and IV move laterally in the opposite direction to the previous lateral movement below the lower warp yarn, achieving a new intersection; Then repeat steps 2 through 5 in a loop to achieve continuous binding of the warp and weft yarns.

[0012] Preferably, there is at least one upper or lower warp yarn passing through the same reed eyelet.

[0015] Preferably, the relative lateral movement and crossing between binding yarn I and binding yarn II are synchronized with the relative lateral movement and crossing between binding yarn III and binding yarn IV.

[0016] Beneficial effects: This invention provides a warp and weft yarn binding device and method for double-sided mesh weaving, which has the following advantages: (1) This invention controls the independent heald frames of the upper and lower layers of binding yarns separately, and uses a composite motion actuator such as a lateral lifting mechanism, heald frame lifting mechanism I / II, guide wheel assembly, and lateral linkage to drive the upper binding yarns I and II to perform lateral crossing and lifting movements above the warp yarns, while the lower binding yarns III and IV perform mirror-like lateral crossing and lifting movements below the warp yarns, thereby achieving synchronous cross binding of the upper and lower layers of warp and weft yarns in a double-sided mesh. This method effectively prevents relative displacement, loose structure, or irreversible deformation between the warp and weft yarns.

[0017] (2) This invention converts the single lifting motion of the transverse lifting mechanism into a combined synchronous lifting and reciprocating transverse motion of the transverse heddle lifting plate through a transverse linkage. This combined motion is then transmitted to multiple transverse heddle frames via guide wheel assemblies on the transverse heddle lifting plate, allowing them to independently lift and lower under the drive of the heddle frame lifting mechanism while simultaneously moving laterally using the guide wheels. This structure achieves a high degree of synchronization and coordination among multiple sets of bonded yarns in actions such as crossing, opening, and resetting. This not only significantly improves the reliability of the bonded yarns and the accuracy of the actions but also optimizes the compactness of the mechanical structure, which is beneficial for high-speed, stable, and efficient weaving production.

[0018] (3) This invention overcomes the structural instability problem caused by reduced yarn contact in large-spacing meshes by replacing the traditional friction-dependent method with active mechanical bonding, making it possible to prepare double-sided mesh fabrics with large pores and high stability, and meeting the needs of high-end applications such as high-precision filtration, geogrids and aerospace structures.

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application. Example

[0021] like Figure 1-2 As shown, a warp and weft yarn binding device for double-sided mesh weaving includes a transverse lifting mechanism 1, a transverse heddle lifting plate I 2, a transverse heddle lifting plate II 3, a heddle frame lifting mechanism I, a heddle frame lifting mechanism II, a guide wheel assembly I 5, a guide wheel assembly II 6, a transverse heddle frame I 7, a transverse heddle frame II 8, a transverse heddle frame III 9, and a transverse heddle frame IV 10, wherein... The lifting drive end of the transverse lifting mechanism 1 is hinged to the transverse lifting plate I2 and the transverse lifting plate II3 respectively, driving the transverse lifting plate I2 and the transverse lifting plate II3 to perform synchronous lifting movements; The transverse lifting plate I2 and the transverse lifting plate II3 are distributed on both sides of the frame 4 along the axis. The transverse lifting plate I2 and the transverse lifting plate II3 are connected to the frame 4 through the transverse connecting rod 11. While the transverse lifting plate I2 and the transverse lifting plate II3 are raised and lowered synchronously, they are driven by the transverse connecting rod 11 to perform reciprocating transverse movement. Guide wheel assembly I5 and guide wheel assembly II6 are respectively mounted on transverse lifting plate I2 and transverse lifting plate II3, and move with transverse lifting plate I2 and transverse lifting plate II3 respectively; Both the transverse heddle frame I7 and the transverse heddle frame III9 are installed in conjunction with the guide wheel assembly I5 and move laterally with the guide wheel assembly I5; Both the transverse heald frame II8 and the transverse heald frame IV10 are installed in conjunction with the guide wheel assembly II6 and move laterally with the guide wheel assembly II6; The lifting drive end of the heald frame lifting mechanism I is connected to the transverse heald frame I7 and the transverse heald frame II8 respectively, driving the transverse heald frame I7 and the transverse heald frame II8 to perform synchronous lifting movements; The lifting drive end of the heald frame lifting mechanism II is connected to the transverse heald frame III 9 and the transverse heald frame IV 10 respectively, driving the transverse heald frame III 9 and the transverse heald frame IV 10 to perform synchronous lifting movements.

[0022] In this invention, the guide wheel assembly I5 includes a guide wheel plate 5-1, at least one set of inner double guide wheels 5-2, and at least one set of outer double guide wheels 5-3. The guide wheel plate 5-1 is mounted on the transverse lifting plate I2. Each set of inner double guide wheels 5-2 includes two inner guide wheels 5-21, which are coaxially mounted on the guide wheel plate 5-1 and located on the front and back sides of the guide wheel plate 5-1, respectively. Each set of outer double guide wheels 5-3 includes two outer guide wheels 5-31, which are coaxially mounted on the guide wheel plate 5-1 and located on the front and back sides of the guide wheel plate 5-1, respectively. The rotation center axes of the inner double guide wheels 5-2 and the outer double guide wheels 5-3 are perpendicular to the transverse lifting plate I2. The inner guide wheels 5-21 and the outer guide wheels 5-31 located on the same side are matched one-to-one to form a clamping groove. The structure of the guide wheel assembly II is the same as that of the guide wheel assembly I. In this embodiment 1, there are two sets of inner guide wheels and two sets of outer guide wheels on the same side.

[0023] In this embodiment 1, the inner guide wheel 5-21 and the outer guide wheel 5-31 are provided with guide grooves along their circumference, which are used to cooperate with the guide frame I7 / II8 / III9 / IV10 to provide stable guidance and support for the lateral heald frame.

[0024] In this invention, guide wheel assembly I5 (guide wheel assembly II) precisely converts the composite motion of the lateral heald lifting plate into the lateral movement of the lateral heald frame. Through the clamping grooves formed by the corresponding engagement of the inner and outer double guide wheels on the same side, the four sets of lateral heald frames are respectively installed and guided. This structure ensures that while the four sets of lateral heald frames are driven to perform independent lifting movements by the heald frame lifting mechanism, they can also be clamped and driven by the guide wheels, achieving precise and stable lateral displacement.

[0025] In this embodiment 1, the horizontal moving heald frames I 7, II 8, III 9 and IV 10 are arranged sequentially in front of and behind each other. The top of the horizontal moving heald frames I 7 and II 8 are provided with a number of yarn guide needles 12, and the bottom edge of the horizontal moving heald frames III 9 and IV 10 is provided with a number of yarn guide needles 12. The horizontal moving heald frames I 7 and II 8 are respectively hinged to the lifting drive end of the heald frame lifting mechanism I, and the horizontal moving heald frames III 9 and IV 10 are respectively hinged to the lifting drive end of the heald frame lifting mechanism II.

[0026] In this invention, the transverse linkage 11 is a parallelogram connector, and one end of the transverse linkage 11 is hinged to the frame 4, and the other end is hinged to the transverse lifting plate I2 or the transverse lifting plate II3.

[0027] The transverse linkage 11, through its parallelogram motion characteristics, can constrain and guide the transverse lifting plates I2 / II3 to generate precise horizontal displacement synchronously during vertical lifting, thus realizing the composite motion of the transverse lifting plates.

[0028] In this invention, both the heald frame lifting mechanism I and the heald frame lifting mechanism II are existing technologies, and any existing lifting device that can drive the transverse heald frame to make periodic up and down movements is applicable. The transverse lifting mechanism 1 is also an existing technology, and any existing lifting device that can drive the transverse lifting plate I and the transverse lifting plate II to make periodic up and down movements is applicable.

[0029] The working principle of this invention is as follows: In this embodiment 1, the working principle of the warp and weft yarn binding device is as follows: The telescopic drive component 1-1 drives the rotating plate I1-2 to reciprocate through its telescopic movement, which in turn drives the rotating plate II1-3 to rotate synchronously with the rotating plate I1-2 via the drive link 1-4. The movement of the rotating plates I1-2 and II1-3 is ultimately converted into the synchronous lifting and lowering of the adjustable lifting link I1-5 and adjustable lifting link II1-6, thereby driving the transverse lifting plate I2 and transverse lifting plate II3 to perform synchronous reciprocating lifting and lowering movements.

[0030] The lateral lifting mechanism drives the lateral lifting plate I2 and lateral lifting plate II3 to perform synchronous lifting and lowering movements. During the lifting and lowering movement of the lateral lifting plate I2, due to the constraint of the lateral connecting rod 11, the lateral lifting plate I2 performs reciprocating lateral movement. Similarly, the lateral lifting plate II3 performs reciprocating lateral movement under the constraint of the lateral connecting rod 11. During the upward movement of the lateral lifting plates I and II3, they move relative to each other under the constraint of the lateral connecting rod 11. During the downward movement, they move in opposite directions under the constraint of the lateral connecting rod 11. At the same time, the lateral lifting plate I2 drives the lateral heddle frame I7 and the lateral heddle frame III9 to produce lateral displacement through the guide wheel assembly I5. The lateral lifting plate II3 drives the lateral heddle frame II8 and the lateral heddle frame IV10 to produce lateral displacement through the guide wheel assembly II6.

[0031] Under the lifting drive of the heald frame lifting mechanism I, the horizontal heald frame I 7 and the horizontal heald frame II 8 move up and down along the clamping slots of the guide wheel assembly I 5 and the guide wheel assembly II 6, respectively. Under the lifting drive of the heald frame lifting mechanism II, the horizontal heald frame III 9 and the horizontal heald frame IV 10 move up and down along the clamping slots of the guide wheel assembly I 5 and the guide wheel assembly II 6, respectively.

[0032] During the lifting and lowering process, the lateral heddle lifters I2 and II3 are constrained in their movement trajectory by the lateral linkage 4: When the lateral heddle frames I7 and II8 rise, lateral heddle lifters I2 and II3 move laterally towards each other, causing the yarns on lateral heddle frames I7 and II8 to cross; simultaneously, lateral heddle frames III9 and IV10 descend, and lateral heddle lifters I2 and II3 move laterally towards each other, causing the yarns on lateral heddle frames III9 and IV10 to cross. Conversely, the yarns on lateral heddle frames I7 and II8, as well as those on lateral heddle frames III9 and IV10, undergo new crossings.

[0033] A method for binding warp and weft yarns in double-sided mesh weaving, based on the binding device of Embodiment 1, sets yarn movement parameters, such as... Figure 3 As shown, binding yarn I 13 passes through the guide needle 12 of the transverse heald frame I 7 and is led to the upper mesh surface of the fabric; binding yarn II 14 passes through the guide needle of the transverse heald frame II 8 and is led to the upper mesh surface of the fabric. Binding yarns I 13 and II 14, in pairs, together with a group of upper warp yarns 18, pass through the same reed eye of the translational reed 17. The axially arranged upper warp yarns alternately form the upper weft opening I, used for passing the upper weft yarn. Binding yarn III 15 passes through the guide needle of the transverse heald frame III 9 and is led to the lower mesh surface of the fabric; binding yarn IV 16 passes through the guide needle 12 of the transverse heald frame IV 10 and is led to the lower mesh surface of the fabric. Binding yarns III 15 and IV 16, in pairs, together with a group of lower warp yarns 19, pass through the same reed eye of the translational reed 17. The axially arranged lower warp yarns alternately form the lower weft opening I, used for passing the lower weft yarn. The specific method of binding the warp and weft yarns is as follows: Step 1: Upper mesh surface: Binding yarn I 13 and binding yarn II 14 move laterally above the upper warp yarn 18 and intersect each other; Lower grid surface: Binding yarns III15 and IV16 move laterally below the lower warp yarn 19 and intersect each other; Step 2: Upper mesh surface: After the transverse crossing, the binding yarn I13 and binding yarn II14 descend simultaneously, forming the upper weaving opening II18-2 with the upper warp yarn 18 of the same reed eye; Lower mesh surface: After the transverse crossing, the binding yarns Ⅲ15 and Ⅳ16 rise simultaneously, and the lower warp yarns with the same reed eye form the lower weave opening Ⅱ19-2; Step 3: Upper mesh surface: The upper weft yarn passes through the alternating upper weft openings I and II; Lower grid surface: The lower weft yarns pass through the alternating lower weave openings I and II; The weft insertion operation is performed simultaneously by shifting the reed 17. Step 4: Upper mesh surface: After the upper warp yarn 18 moves up and down alternately, the binding yarn I 13 and binding yarn II 14 rise simultaneously above the upper warp yarn 18; Lower mesh surface: After the lower warp 19 moves up and down alternately, the binding yarn III 15 and binding yarn IV 16 simultaneously descend below the lower warp 19; Step 5: Upper mesh surface: Binding yarn I 13 and binding yarn II 14 are moved laterally in the opposite direction to the previous lateral movement above the upper warp yarn 18 to achieve a new intersection; Lower grid surface: Binding yarns III15 and IV16 move laterally in the opposite direction to the previous lateral movement below the lower warp 19 to achieve a new intersection; Then repeat steps 2 through 5 in a loop to achieve continuous binding of the warp and weft yarns.

[0034] In this embodiment 1, at least one upper warp yarn 18 or lower warp yarn 19 passes through the same reed eye. Preferably, there are two upper warp yarns 18 located in the same reed eye, moving synchronously. Along the arrangement direction of the upper warp yarns 18, the upper warp yarns 18 alternately form the upper weave opening I. The specific alternating arrangement can be selectively designed by those skilled in the art according to actual needs, for example, alternating between upper and lower warp yarns at intervals. The arrangement of the lower warp yarns 19 is also determined by those skilled in the art according to actual needs.

[0035] In this embodiment 1, the weft angle of upper weft I is greater than or equal to the weft angle of upper weft II, and the weft angle of lower weft I is greater than or equal to the weft angle of lower weft II. This angular relationship ensures that the weft yarn can pass smoothly through all wefts, thereby further guaranteeing the continuity of the weaving process and the integrity of the fabric structure.

[0036] In this embodiment 1, the relative lateral movement and crossing between binding yarn I 13 and binding yarn II 14 are synchronized with the relative lateral movement and crossing between binding yarn III 15 and binding yarn IV 16.

[0037] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
