Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a heddle weaving process and equipment for a rapier loom. Background Technology

[0002] Rapier looms are widely used in the weaving of various fabrics due to their advantages of stable weft insertion, wide range of applicable yarns, and high weaving efficiency. Conventional rapier looms are only equipped with ordinary heddles and can only weave fabrics with common weave structures such as plain weave and twill weave.

[0003] Twill weave fabrics rely on the intertwining and binding of twill warp and ground warp yarns to form a stable twill structure. They are characterized by good weft locking performance, a robust structure, and resistance to unraveling, and are commonly used in the production of home textiles, decorative fabrics, and industrial fabrics. However, in existing technologies, directly adding twill heddles to ordinary rapier looms generally results in problems such as unreasonable warp threading, asynchronous heddle movement with the loom's main shaft, and mismatched warp and weft tension. This leads to problems during weaving such as warp yarn disorder, warp breakage, uneven fabric twisting, and weft slippage. Conventional weaving processes cannot meet the demands of high-speed, stable weaving of twill weave fabrics on rapier looms, resulting in low yield and poor weaving stability. Furthermore, traditional weft feeders lack corresponding heat dissipation structures; heat accumulation inside the equipment accelerates component aging, easily triggering cascading failures and shortening the equipment's lifespan. Therefore, this paper proposes a twill heddle weaving process and equipment for rapier looms to address these issues. Summary of the Invention

[0004] In view of the problems mentioned in the background art, the purpose of this invention is to provide a heddle weaving process and equipment for a rapier loom to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is: a heddle weaving process for a rapier loom, comprising the following steps: S1: Warp threading: The warp yarns and ground warp yarns are divided into separate warp sections and then passed through the stop warp piece in sequence; the warp yarns are threaded into the heddles of the movable heddle, and the ground warp yarns are threaded into the heddles of the ground heddle; and each set of corresponding warp yarns and ground warp yarns are threaded into the same tooth of the reed to complete the warp threading arrangement. S2: Installation and commissioning: Install this equipment in the corresponding position on the rapier loom, and calibrate the heddle swing stroke to keep it synchronized with the loom spindle rotation phase; then adjust the warp tension, weft feeder tension and weft feed speed to make the warp and weft tensions suitable for the rapier weaving conditions; S3: Weaving: Start the rapier loom. The loom's main shaft drives the movable heddles to make periodic interlacing reciprocating motions of the warp yarns. The warp yarns and the ground warp yarns cooperate to form regular twill weave openings. The rapier completes the weft insertion action according to a predetermined trajectory. The weft yarn is introduced into the warp opening and locked by the twill twisting structure. The loom runs continuously and gradually weaves the twill weave structure fabric. S4: Finishing after weaving: After the weaving process is completed, the fabric is removed from the loom, impurities and yarn ends are removed from the surface of the fabric, and the finished product is obtained after setting treatment.

[0006] The present invention also provides a device for the heddle weaving process of a rapier loom, including a weft feeder, a weft drum on one side of the weft feeder, a heat dissipation shell on the top of the weft feeder, and a cleaning mechanism on the top of the heat dissipation shell; The heat dissipation shell includes a housing, which is fixedly installed on the top of the weft feeder. A heat-conducting plate is fixedly installed on the inner side of the housing. A heat-conducting rib is fixedly connected to the bottom of the heat-conducting plate. A heat dissipation fin is fixedly installed on the top of the heat-conducting plate through the inner wall of the housing.

[0007] The inner side of the housing has a perforation, and the top of the heat-conducting plate passes through the perforation.

[0008] The heat-conducting ridge is wavy in shape, and its outer surface is coated with graphene.

[0009] The cleaning mechanism includes a mounting shell, which is fixedly mounted on the top of a heat sink. A screw is rotatably connected to the inner side of the mounting shell, and a moving block is threadedly connected to the outer side of the screw. The moving block is slidably connected to the inner side of the mounting shell. A moving frame is fixedly mounted on one side of the moving block, and a cleaning brush is movably mounted on one side of the moving frame. A mounting cavity is opened on the inner side of the mounting shell, and a rotating rod is rotatably connected to the inner side of the mounting cavity. A second bevel gear is fixedly mounted at the end of the rotating rod. A micro motor is fixedly mounted at the bottom of the heat sink. A first bevel gear is fixedly mounted at the output end of the micro motor and at one end of the screw. The first bevel gear at one end of the screw meshes with the second bevel gear at the top of the rotating rod, and the first bevel gear at the output end of the micro motor meshes with the second bevel gear at the bottom of the rotating rod.

[0010] Guide rods are symmetrically fixedly installed on the inner side of the mounting shell, and the moving block is slidably connected to the outer side of the guide rods.

[0011] A sleeve is fixedly installed on one side of the cleaning brush, and a through hole is opened on the inner side of the movable frame. One end of the sleeve is threaded through the through hole and connected to a hand-tightening bolt.

[0012] A matching groove is provided on one side of the movable frame, and the rod of the cleaning brush is inserted into the matching groove.

[0013] The advantages of this invention are: 1. This invention limits the insertion of the twill warp and the ground warp into the same reed teeth, which conforms to the inherent mechanism of twill weaving. The twill pattern is regular and uniform, the fabric structure is tight, the weft locking effect is excellent, and the defects of weft slippage and loose fabric surface are effectively avoided.

[0014] 2. This invention synchronizes the phase of the heddle with the main shaft of the loom by calibrating the heddle and optimizing the warp and weft yarn tension parameters, adapting to the high-speed operation characteristics of the rapier loom. The warp yarn runs smoothly during the weaving process, greatly reducing weaving faults such as warp breakage, warp disorder, and poor shedding.

[0015] 3. This invention employs a heat dissipation shell design on the weft feeder. Based on the principle of hot air rising, it utilizes the heat-conducting ridges at the heat-conducting plate inside the shell for efficient heat absorption, quickly transferring the heat inside the weft feeder to the outside of the shell, and then dissipating it rapidly using the heat dissipation fins on the heat-conducting plate. This effectively protects the weft feeder from heat dissipation, thereby extending its service life. 4. This invention adds a cleaning mechanism to the heat sink shell. Given that there are many airborne particles in the textile processing environment, the cleaning mechanism drives the cleaning brush to move back and forth, which can remove the blockages mixed in with the heat sink fins, thereby avoiding the impact of the blockages on the heat dissipation effect of the heat sink fins.

[0020] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail. The heddle weaving process of this rapier loom includes the following steps: S1: Warp threading: The warp yarns and ground warp yarns are divided into separate warp sections and then passed through the stop warp piece in sequence; the warp yarns are threaded into the heddles of the movable heddle, and the ground warp yarns are threaded into the heddles of the ground heddle; and each set of corresponding warp yarns and ground warp yarns are threaded into the same tooth of the reed to complete the warp threading arrangement. S2: Installation and commissioning: Install this equipment in the corresponding position on the rapier loom, and calibrate the heddle swing stroke to keep it synchronized with the loom spindle rotation phase; then adjust the warp tension, weft feeder tension and weft feed speed to make the warp and weft tensions suitable for the rapier weaving conditions; S3: Weaving: Start the rapier loom. The loom's main shaft drives the movable heddles to make periodic interlacing reciprocating motions of the warp yarns. The warp yarns and the ground warp yarns cooperate to form regular twill weave openings. The rapier completes the weft insertion action according to a predetermined trajectory. The weft yarn is introduced into the warp opening and locked by the twill twisting structure. The loom runs continuously and gradually weaves the twill weave structure fabric. S4: Finishing after weaving: After the weaving process is completed, the fabric is removed from the loom, impurities and yarn ends are removed from the surface of the fabric, and the finished product is obtained after setting treatment.

[0021] This application discloses equipment for the heddle weaving process on a rapier loom. (Refer to...) Figures 1-4The equipment used in the heddle weaving process of the rapier loom includes a weft feeder 1, a weft drum 2 on one side of the weft feeder 1, a heat dissipation shell 3 on the top of the weft feeder 1, and a clearing mechanism 4 on the top of the heat dissipation shell 3. The weft feeder 1 also includes a motor and drive system, a tension control device, a braking system, a yarn guide, a sensor and control system, etc. It is a relatively mature existing technology product known on the market, so it will not be described in detail here. The heat dissipation shell 3 includes a shell 301, which is fixedly installed on the top of the weft feeder 1. A heat-conducting plate 302 is fixedly installed on the inner side of the shell 301. A heat-conducting rib 304 is fixedly connected to the bottom of the heat-conducting plate 302. A heat dissipation fin 303 is fixedly installed through the inner wall of the shell 301 on the top of the heat-conducting plate 302. The shell 301 can expand the heat conduction area through the internal wavy heat-conducting rib 304, which can accelerate the heat conduction effect inside the weft feeder 1. At the same time, the heat is transferred to the heat dissipation fin 303 through the heat-conducting plate 302. The heat dissipation fin 303 can help the heat to be quickly dissipated into the air. The cleaning mechanism 4 includes a mounting shell 401, which is fixedly mounted on the top of the heat sink 3. A screw 402 is rotatably connected to the inner side of the mounting shell 401, and a moving block 408 is threadedly connected to the outer side of the screw 402. The moving block 408 is slidably connected to the inner side of the mounting shell 401. A moving frame 403 is fixedly mounted on one side of the moving block 408, and a cleaning brush 6 is movably mounted on one side of the moving frame 403. A mounting cavity 407 is opened on the inner side of the mounting shell 401, and a rotating rod 406 is rotatably connected to the inner side of the mounting cavity 407. A second bevel gear 405 is fixedly mounted on the end of the rotating rod 406. A micro motor 409 is fixedly mounted on the bottom of the heat sink 3. A first bevel gear 404 is fixedly mounted on the output end of the micro motor 409 and one end of the screw 402. The first bevel gear 404 at one end of the screw 402 meshes with the second bevel gear 405 at the top of the rotating rod 406. The micro motor 409 is connected to the first bevel gear 404 at its output end and the second bevel gear 405 at the bottom of the rotating rod 406. The first bevel gear 404 at the output end of the micro motor 409 meshes with the second bevel gear 405 at the bottom of the rotating rod 406, so that the second bevel gear 405 at the top of the rotating rod 406 meshes with the first bevel gear 404 at one end of the screw 402. This allows the screw 402 to rotate in the mounting housing 401. The rotation of the screw 402 causes the moving block 408 connected to its outer thread to slide. At the same time, the moving block 408 drives the cleaning brush 6 through the moving frame 403, which can move back and forth in the gap of the heat dissipation fins 303 to facilitate cleaning of the heat dissipation gaps of the heat dissipation fins 303 and prevent the accumulation of blockages from affecting heat dissipation. The micro motor 409 is controlled by the control module to operate once every certain period of time to remove debris from the gaps of the heat dissipation fins 303.

[0022] Reference Figure 2 and Figure 3The inner side of the housing 301 has a perforation 12, and the top of the heat-conducting plate 302 passes through the perforation 12. The heat-conducting ridge 304 is wavy in shape, and the outer surface of the heat-conducting ridge 304 is coated with graphene 7. The top of the heat-conducting plate 302 can easily pass through the housing 301 through the perforation 12 on the housing 301. The wavy design of the heat-conducting ridge 304 can expand the heat-conducting surface and improve the heat conduction effect. At the same time, the graphene coating 7 is added to the outer surface of the heat-conducting ridge 304. The high thermal conductivity of the material coating can further improve the heat conduction effect of the heat-conducting ridge 304.

[0023] Reference Figure 2 Guide rods 5 are symmetrically fixedly installed on the inner side of the mounting shell 401, and the moving block 408 is slidably connected to the outer side of the guide rods 5. The moving block 408 can slide inside the mounting shell 401 through the guide rods 5 installed on the inner side of the mounting shell 401.

[0024] Reference Figure 4 A sleeve 8 is fixedly installed on one side of the cleaning brush 6. A through hole 9 is opened on the inner side of the moving frame 403. One end of the sleeve 8 passes through the through hole 9 and is threaded with a hand-tightening bolt 10. A mating groove 11 is opened on one side of the moving frame 403. The rod of the cleaning brush 6 is inserted into the mating groove 11. By installing the sleeve 8 on the cleaning brush 6, when installing the cleaning brush 6, the sleeve 8 is passed through the through hole 9 on the moving frame 403 and then connected and fixed with the sleeve 8 by the hand-tightening bolt 10. This facilitates the subsequent disassembly and replacement of the cleaning brush 6. By opening a mating groove 11 on one side of the moving frame 403, when installing the cleaning brush 6 on the moving frame 403, it is inserted into the mating groove 11 and then fixed, resulting in a more stable installation.

[0025] During use, the housing 301 expands the heat conduction area through the internal wave-shaped heat-conducting ridges 304, accelerating the heat conduction effect inside the weft feeder 1. Simultaneously, heat is transferred to the heat dissipation fins 303 via the heat-conducting plate 302. The heat dissipation fins 303 help the heat dissipate quickly into the air. The first bevel gear 404 at the output end of the micro motor 409 meshes with the second bevel gear 405 at the lower end of the rotating rod 406, causing the second bevel gear 405 at the upper end of the rotating rod 406 to mesh with the first bevel gear 404 at one end of the screw 402, thereby enabling the screw 402 to... The screw 402 rotates within the mounting housing 401, causing the sliding block 408, which is threadedly connected to its outer side, to slide. Simultaneously, the sliding block 408 drives the cleaning brush 6 via the moving frame 403, allowing it to move back and forth in the gaps of the heat dissipation fins 303. This facilitates cleaning the heat dissipation gaps of the heat dissipation fins 303, preventing the accumulation of blockages that could affect heat dissipation. When installing the cleaning brush 6, insert it into the mating groove 11 of the moving frame 403. Simultaneously, after the sleeve 8 on the cleaning brush 6 passes through the through hole 9 on the moving frame 403, it is connected and fixed to the sleeve 8 using the hand-tightening bolt 10.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
