The device includes a machine base, with a warp buffer mechanism at the front end of the machine base. After the warp yarn is fed, it is led out through the warp buffer mechanism. The middle part of the machine base is provided with multiple hem frames, a yarn guide plate, a weft yarn feeding mechanism, and a knitting needle mechanism. The warp yarn is woven into a ribbon through the hem frames, yarn guide plate, weft yarn feeding mechanism, and knitting needle mechanism.

Description

Technical Field

[0001] This invention relates to the field of equipment technology for processing ribbons, and particularly to a heavy-duty ribbon weaving machine. Background Technology

[0002] The ribbons produced by heavy-duty ribbon looms are woven from hundreds or thousands of warp and weft threads. Due to the large number of warp threads, the corresponding hem frames in heavy-duty ribbon looms are equipped with numerous lifting and lowering structures to connect and support the warp threads. This makes the hem frame structure, which provides the lifting and lowering structure for the warp threads to interweave, extremely complex and numerous. The threading of warp threads in the hem frame structure and the re-sorting of broken warp threads have become extremely difficult and cumbersome due to the complex structure of modern ribbon looms, which is not conducive to the rapid change of ribbon loom specifications.

[0003] Furthermore, webbing, especially special webbing with a thickness of 7mm or more, needs to be used in special applications. It is a high-elasticity, high-strength webbing. During the weaving process, it needs to be woven with a predetermined pre-tension to achieve the required elasticity and strength. As a result, during the tape exiting the webbing process, due to the high pre-tension strength of the warp threads, the pre-tensioned warp threads generate a rebound force on the woven tape. Therefore, the woven tape is prone to loosening during the tape exiting process, which affects the elasticity and strength of the tape and is not conducive to maintaining the high elasticity and high strength performance of the woven tape.

[0004] Therefore, for some special webbing with a thickness of 7mm or more, in order to prevent slippage or backing during the weaving process, in addition to making special designs for the weft insertion route, it is also necessary to add relevant mechanisms.

[0005] Therefore, in response to these issues, this invention designs a simple heavy-duty ribbon weaving machine to solve the problems of complex and cumbersome warp threading and warp thread handling after breakage in the prior art, as well as the problem of the ribbon loosening due to the elastic force generated by the pre-tightened warp threads on the woven ribbon during the ribbon exit process, which affects the elasticity and strength of the ribbon, thereby meeting the special requirements of weaving special ribbons with a thickness of more than 7mm. Summary of the Invention

[0006] To address the problems of existing ribbon weaving machines, this invention proposes a heavy-duty ribbon weaving machine, employing the following technical solution: A heavy-duty ribbon weaving machine includes a machine base. The front end of the machine base is equipped with a warp buffer mechanism, through which warp threads are led out after being fed. The middle of the machine base is equipped with multiple vertically movable frame hems, a yarn guide plate, a weft yarn feeding mechanism, and a needle mechanism. Warp threads are woven into a ribbon through the frame hems, the yarn guide plate, the weft yarn feeding mechanism, and the needle mechanism. The rear of the machine base is equipped with a ribbon anti-loosening mechanism to lead out the ribbon. Each frame hem includes a square frame body. Multiple movable thread pieces are vertically mounted inside the frame body. A threading point is opened in the middle of each thread piece. Multiple warp threads pass through the threading holes and then through the yarn guide plate. A lifting plate is located at the bottom of the frame, connected to a lifting structure for the hem frames to move up and down. The lifting structure includes a lifting guide plate with multiple adjustable holes arranged in a row, the number of which is the same as the number of hem frames. A connecting block is correspondingly connected to one of the adjustable holes on the lifting guide plate, and the hem frames are fixedly connected via the connecting block. The hem frames are ordered from front to back according to the sequence number N, and the lifting guide plates are ordered from one side of the base to the other according to the sequence number L. The maximum value of the sequence number N is defined as N0. max Multiple adjustment holes are defined and ordered by number M according to their direction from front to rear after installation. Among the multiple brown frames, those with an odd number of N frames are located on one side of the base, and their landing plates are arranged in a stepped distribution. Furthermore, the connection between the multiple brown frames with an odd number of N frames and the landing guide plate with number L satisfies the formula... On the other side of the base, a plurality of brown frames satisfying N is an even number, and their landing plates are arranged in a stepped distribution. The connection between the brown frames satisfying N is an even number and the landing guide plate numbered L satisfies the formula... Furthermore, the connecting block of the Nth brown frame and the Mth adjusting hole are connected in accordance with the formula M=N. A pressure wheel is rotatably mounted at the first end of each lifting guide plate. The pressure wheel presses against the cam structure, which is movably connected to the base and reciprocates. The lifting structure drives the lifting guide plate to move up and down via the pressure wheel, thereby driving the corresponding brown frame to move up and down through the corresponding lifting plate, thus realizing the up and down movement of the warp threads and the weft threads interlacing to weave the ribbon. The brown frames and lifting structure of this invention form a stepped distribution structure, and the staggered connection structure of odd and even brown frames avoids positional interference between connecting blocks on adjacent brown frames during installation, greatly simplifying the connection structure of the brown frames and lifting structure.

[0007] Furthermore, the landing plate has an insertion slot at its end. The connecting block has a first connecting slot at its upper part corresponding to the end of the landing plate, and a second connecting slot at its lower part perpendicular to the first connecting slot. The end of the landing plate is inserted into the first connecting slot. A first fixing screw is provided outside the first connecting slot, and the landing plate is fixedly connected through the insertion slot of the landing plate by the first fixing screw. The landing guide plate is connected to the connecting block through the second connecting slot. A second fixing screw is provided outside the second connecting slot, and a positioning and rotating connection is formed by the second fixing screw through the adjustment hole on the landing guide plate. Through this connection method, the frame is quickly connected to the landing guide plate via the connecting block, resulting in a simple and robust connection structure.

[0008] Furthermore, the lifting guide plate has a counterweight at the end furthest from the pressure roller. The weight of the counterweight is configured such that the connecting block is positioned closer to the adjustment hole on the lifting guide plate, with a heavier counterweight therefrom, and vice versa. A heavier counterweight is used when the counterweight is closer to the adjustment hole, and a lighter counterweight is used when the counterweight is farther from the adjustment hole. This improves the balance of the lifting guide plate and enhances its stability.

[0009] Furthermore, the base includes a top base, with side bases on both sides of the top base. The side bases have brown frame positioning grooves corresponding to the brown frame. The brown frame's frame body is positioned vertically and vertically through the brown frame positioning grooves on both sides. The upper part of the brown frame body is provided with a connecting rope that connects to the top base. The base has a positioning seat on its bottom plate for positioning the lifting guide plate. The positioning seat has a pentagonal structure composed of a rectangle and an isosceles triangle. The positioning seat has multiple lifting positioning grooves corresponding to the lifting guide plate. The lifting guide plate is positioned during the lifting process through the lifting positioning grooves, ensuring the stable lifting and lowering of the lifting guide plate. At the same time, the connecting block connected to the lifting guide plate falls outside the positioning seat.

[0010] Furthermore, a lifting spring is rotatably connected to the lifting guide plate near the pressure wheel. One end of the lifting spring is connected to a connecting rod, and both sides of the connecting rod are fixed to the base. Through the lifting spring, the lifting guide plate is pulled taut in the direction of the connecting rod. The lifting spring and the cam structure work together to form an elastic, mutually balanced connection structure, ensuring a smoother and more stable linkage between the lifting guide plate and the cam structure.

[0011] Furthermore, the cam structure includes a cam assembly, a slider, a slide rail, and a first power mechanism for the reciprocating movement of the cam assembly. The cam assembly consists of multiple sets of cams corresponding to the lifting guide plate. Each cam includes a double-arc plate with annular protrusions on both sides. A balance wheel is fitted onto each protrusion. A cam surface is provided on the edge side of the double-arc plate, and a pressing wheel presses against the cam surface. A cam connecting shaft is fitted inside the cam, and multiple cams are connected as a whole through the cam connecting shaft. The multiple cams are installed at a predetermined angle. Cam supports are provided on both sides of the cam connecting shaft for connection, and the cam connecting shaft is secured by locking screws. The cam assembly is locked and fixed to the cam support. A slider is also provided at the bottom of the cam support. The cam assembly is slidably connected to the slide rail via the slider. An integrally connected connecting plate is provided between the cam supports. The first power mechanism includes a third servo motor and a second concentric wheel coaxially connected to the third servo motor. A second eccentric column is provided on the second concentric wheel, and a cam push rod is rotatably provided on the second eccentric column. The cam push rod is rotatably connected to the connecting plate. Driven by the third servo motor, the cam assembly reciprocates on the slide rail, abutting against the pressure wheel on the cam surface. Therefore, the change in the arc surface of the cam creates a regular up-and-down movement. In this invention, the cam can adjust its installation angle according to the connected frame, thereby achieving different rhythmic changes in the up-and-down movement of the cam to match the weft yarn feeding process.

[0012] Furthermore, the weft yarn feeding mechanism includes a weft yarn handle and a weft hook. One end of the weft yarn handle is rotatably connected to a first servo motor via a shaft. The weft hook is connected to the other end of the weft yarn handle. The end of the weft hook is provided with a weft yarn hole for yarn feeding. The first servo motor reciprocates at a fixed angle, thereby driving the weft hook to swing from one side of the machine base to the other side of the machine base according to the up and down movement of the frame, thus realizing the feeding of the weft yarn.

[0013] Furthermore, in the yarn feeding structure, one end of the weft hook is connected to a tensioning mechanism. The tensioning mechanism includes a pull rope connected to the weft hook, which is connected to a tension spring via a spring connecting end. The other end of the tension spring is connected to the base plate of the machine base via a spring connecting end. By setting up the tensioning mechanism, the weft hook can move more smoothly and steadily during its movement due to the elastic stretching of the tension spring.

[0014] Further, the knitting needle mechanism includes a knitting needle fixing seat and a knitting needle. The knitting needle includes a knitting needle bar, and a knitting needle hook is provided at the end of the knitting needle bar. A needle withdrawal rod is provided that rotates between the knitting needle hook and the knitting needle bar. The knitting needle hook and the knitting needle bar form an openable or closeable structure. A limiting post is provided on the side of the knitting needle bar away from the needle withdrawal rod. The knitting needle fixing seat includes a first fixing seat, and a push groove is provided on the first fixing seat. A limiting groove corresponding to the limiting post is also provided in the push groove. The knitting needle bar is movably disposed in the push groove and positioned by the limiting groove. One end of the needle bar is connected to a needle arm push rod, and the needle arm push rod is rotatably connected to a push plate. The push plate moves the needle back and forth along the push groove through the needle arm push rod. The needle moves back and forth to pull and untie the weft yarn, thus achieving the interlacing of the weft and warp yarns. A second power mechanism for the reciprocating movement of the needle is also provided at one end of the push plate. The second power mechanism includes a motor and a first concentric wheel coaxially connected to the motor. A first eccentric column is provided on the first concentric wheel and is rotatably connected to the push plate. Through the rotation of the motor, the needle moves back and forth along the push groove.

[0015] Furthermore, the webbing anti-loosening mechanism includes a guide rod assembly, which comprises a first guide rod, a second guide rod, a third guide rod, and a fourth guide rod. The first guide rod, the second guide rod, the third guide rod, and the fourth guide rod are connected to the machine base in a Z-shape. The second guide rod and the third guide rod are rotatably connected to the machine base via a one-way bearing. An anti-loosening rod assembly is also provided between the fourth guide rod and the third guide rod. The anti-loosening rod assembly includes a first anti-loosening rod and a second anti-loosening rod. Both the first anti-loosening rod and the second anti-loosening rod are rotatably connected to the machine base. A second servo is provided on one side of either the first anti-loosening rod or the second anti-loosening rod. The servo motor has a gear coaxially connected to each of the first and second anti-loosening rods on the other side, and the two gears mesh with each other. The rotation of the second servo motor drives the anti-loosening rod assembly to rotate synchronously and in opposite directions. The fourth guide rod is connected to a pre-tension adjustment structure. Through the pre-tension adjustment structure, the gap between the fourth guide rod and the second anti-loosening rod can be adjusted. The webbing forms two turns along the lower surface of the first guide rod and around the outer surfaces of the second and third guide rods. The webbing is led out between the first and second anti-loosening rods and is pressed and led out from the gap between the second and fourth guide rods. The webbing is guided out between the first and second anti-loosening rods via the first, second, and third guide rods. Driven by the second servo motor, the first and second anti-loosening rods squeeze and rotate, providing the power to pull out the webbing. Finally, the compressed webbing is pulled out to the outside via the fourth guide rod. After being tightly wound by the first and second anti-loosening rods, the webbing ensures that the subsequent webbing generates a rebound force during the weaving process, pulling the woven webbing. Moreover, the second and third guide rods are equipped with one-way bearings, allowing them to rotate in the direction of webbing exit. The rebound force generated by the webbing during the weaving process pulls on the second and third guide rods, preventing them from rotating in the opposite direction, further improving the webbing anti-loosening exit.

[0016] Furthermore, the pre-tightening adjustment structure includes a connecting plate, a fixed block, and an adjustment assembly. One end of the connecting plate is connected to the end of the fourth guide rod, and the middle part of the connecting plate is rotatably connected to the fixed block. The other end of the connecting plate is provided with an adjustment groove. The adjustment assembly includes two opposing first fixed posts, which are connected and fixed by a second fixed post. The first fixed posts are provided with sliding grooves, and the first and second adjustment posts are slidably connected between the two sliding grooves. An adjustment spring is provided between the first and second adjustment posts. An adjustment screw is provided in the middle of one of the second fixed posts. The adjustment screw passes through the second fixed post and is threadedly connected to the second adjustment post. A connecting hole is provided on the first adjustment post, and a pin is provided in the adjustment groove. The pin passes through the adjustment groove and connects to the connecting hole. By rotating the adjustment screw, the second adjustment post moves and presses against the first adjustment post through the adjustment spring. The first adjustment post slides and causes the connecting plate to swing around the fixed block as a fulcrum. The fourth guide rod elastically presses the extended webbing onto the surface of the second anti-loosening rod. By adjusting the assembly, the fourth guide rod adjusts and tightens the webbing that the second anti-loosening rod rotates out to the outside.

[0017] This invention, through a rational configuration design of the landing plates of the brown frame from front to rear, forms a stepped distribution structure between the brown frame and the landing structure. The staggered connection structure of odd and even-numbered brown frames avoids positional interference between connecting blocks on adjacent brown frames during installation, greatly simplifying the connection structure between the brown frame and the landing structure. Furthermore, by incorporating a webbing anti-loosening mechanism, this invention effectively prevents the webbing from loosening during the webbing exit process due to the rebound force generated by the pre-tensioned warp threads. Therefore, the high elasticity and high strength of the webbing are maintained, improving the quality of the webbing and broadening its application in special applications such as parachutes and aircraft landing pads. It is particularly suitable for special webbing with a thickness of 7mm or more. Attached Figure Description

Detailed Implementation

[0036] The embodiments of the present invention will now be briefly described with reference to the accompanying drawings.

[0037] In this invention, N, M, and L represent positive integers.

[0038] A heavy-duty ribbon weaving machine, Figures 1-2 The device includes a base 4, with a warp buffer mechanism 1 at the front end of the base 4. The warp buffer mechanism 1 can be referred to in the applicant's prior patent application "A warp buffer device for stopping a heavy-duty weighing machine" (patent application number CN2023209363575). The warp yarn forms a stable warp yarn supply structure for the brown frame 2 of the heavy-duty weighing machine through the warp buffer mechanism 1. After the warp yarn is fed, it is led out through the warp buffer mechanism 1 into the brown frame 2 of the base 4.

[0039] The machine base 4 includes a top base 41, with side bases 42 on both sides of the top base 41. Between the two side bases 42, there are multiple vertically movable palm frames 2. The side bases 42 are provided with palm frame positioning grooves 421 corresponding to the palm frames 2. The palm frame 2 is positioned vertically and vertically through the palm frame positioning grooves 421 on both sides. The machine base 4 is also provided with a yarn guide plate 3, a weft yarn feeding mechanism 5, and a knitting needle mechanism 6. The warp yarn passes through the palm frames 2, the yarn guide plate 3, the weft yarn feeding mechanism 5, and the knitting needle mechanism 6 to weave a webbing 10. The rear of the machine base 4 is provided with a webbing anti-loosening mechanism 7 to guide out the webbing 10.

[0040] Reference Figure 7 Each frame 2 includes a square frame 21. Inside the frame 21, multiple movable thread pieces 22 are installed vertically. Each thread piece 22 has a thread hole 221 in the middle. Specifically, the thread pieces 22 are connected together by two horizontal plates 24 set on the frame 21. Usually, the number of thread pieces 22 is set to 40-60 depending on the size of the webbing 10. The number of warp threads is threaded through the thread hole 221 of each thread piece 22 according to the weaving process of the webbing 10. The upper part of the frame 21 of the frame 2 is provided with a connecting rope 23 connected to the top seat 41 of the machine base 4. At the bottom of the frame 21, there is a lifting plate 211. The end of the lifting plate 211 is provided with a plug groove 212 for connection. The lifting plate 211 is connected to a lifting structure 9 for the frame 2 to lift up and down. The frame 2 lifts up and down through the lifting structure 9. The lifting up and down of the frame 2 drives the warp threads to interweave with the weft threads to weave the webbing 10.

[0041] Reference Figure 3 , Figure 4 and Figure 16The lifting structure 9 includes a lifting guide plate 91 with multiple adjustment holes 911 arranged on it. The number of adjustment holes 911 is the same as that of the brown frame 2. A connecting block 93 is connected to one of the adjustment holes 911 on the lifting guide plate 91. The lifting plate 211 of the brown frame 2 is fixedly connected by the connecting block 93. A pressure wheel 96 is rotatably mounted on the first end 913 of each lifting guide plate 91. The pressure wheel 96 presses against the cam structure 8. The cam structure 8 is movably connected to the bottom of the base 4 and moves back and forth. The lifting structure 9 drives the lifting guide plate 91 to move up and down through the pressure wheel 96, and thereby drives the corresponding brown frame 2 to move up and down through the corresponding lifting plate 211 to realize the up and down movement of the warp and the weft to weave the ribbon 10.

[0042] Reference Figure 17 The connecting block 93 has a first connecting groove 931 at its upper part corresponding to the end of the landing plate 211, and a second connecting groove 932 at its lower part that is perpendicular to the first connecting groove 931. The end of the landing plate 211 is inserted into the first connecting groove 931. A first fixing screw 933 is provided on the outside of the first connecting groove 931. The first fixing screw 933 passes through the insertion groove 212 of the landing plate 211 and is fixed and locked at both ends by the first fixing screw 933. The landing guide plate 91 is connected to the connecting block 93 through the second connecting groove 932. A second fixing screw 934 is provided on the outside of the second connecting groove 932. The second fixing screw 934 forms a positioning and rotating connection through the adjustment hole 911 on the landing guide plate 91. The brown frame 2 is quickly connected together by the connecting block 93 and the landing guide plate 91. The connection structure is simple and firm.

[0043] Reference Figure 6 Define multiple brown frames 2 arranged from front to back in sequence number N; define multiple landing guide plates 91 arranged from one side of the base 4 to the other in sequence number L; define the maximum value of the sequence number N as N. max Multiple adjustment holes 911 are defined and ordered by number M from front to rear after installation. Among the multiple brown frames 2, those with an odd number of N frames are located on one side of the base 4, and their landing plates 211 are arranged in a stepped distribution. Furthermore, the connection between the brown frames 2 with an odd number of N frames and the landing guide plate 91 with number L satisfies the formula... Among the multiple brown frames 2, those satisfying N being an even number are located on the other side of the base 4, and their landing plates 211 are arranged in a stepped distribution. The brown frames 2 satisfying N being an even number are connected to the landing guide plate 91 with the sequence number L, satisfying the formula... Furthermore, the connection block 93 connected to the Nth brown frame 2 and the connection to the Mth adjustment hole 911 satisfy the formula M=N.

[0044] In this embodiment, specifically, the number of brown frames 2 is 14, that is, N. max =14, and the corresponding landing guide plates 91 are also 14. The connection relationship between the Nth brown frame 2 and the Lth landing guide plate 91, and between the Nth brown frame 2 and the Mth adjustment hole 911 on the Lth landing guide plate 91, is shown in Table 1 below. M 1 2 3 4 5 6 7 8 9 10 11 12 13 14 L 1 14 2 13 3 12 4 11 5 10 6 9 7 8 For example, the first brown frame 2 is connected and installed on the first adjustment hole 911 of the first lifting guide plate 91, the second brown frame 2 is connected and installed on the second adjustment hole 911 of the fourteenth lifting guide plate 91, and so on to achieve the positioning connection between multiple brown frames 2 and the lifting guide plate 91.

[0045] The above-described connection and installation method forms a stepped distribution structure between the brown frame 2 and the lifting structure 9. The staggered connection structure of the odd and even number of brown frames 2 avoids positional interference between the connecting blocks 93 connected to adjacent brown frames 2 during installation, greatly simplifying the connection structure between the brown frame 2 and the lifting structure 9. Since the connecting blocks 93 can be made larger, the corresponding connection is more secure.

[0046] The base 4 has a base plate 44 with a positioning seat 45 for positioning the lifting guide plate 91, as shown in the figure. Figure 8 The positioning seat 45 has a pentagonal structure composed of a rectangle and an isosceles triangle. The positioning seat 45 has multiple lifting and lowering positioning grooves 451 corresponding to the lifting and lowering guide plate 91. The lifting and lowering guide plate 91 is positioned during the lifting and lowering process through the lifting and lowering positioning grooves 451, which ensures the stable lifting and lowering of the lifting and lowering guide plate 91. At the same time, the connecting block 93 connected to the lifting and lowering guide plate 91 falls outside the positioning seat 45.

[0047] The lifting guide plate 91 has a counterweight 92 at the end furthest from the pressure roller 96. The weight of the counterweight 92 is configured such that the counterweight is heavier when the connecting block 93 is closer to the adjustment hole 911 on the lifting guide plate 91, and lighter when it is farther away. The closer the counterweight 92 is to the adjustment hole 911, the better the balance of the lifting guide plate 91 is achieved, thus improving its stability.

[0048] Among them, the lifting guide plate 91 is rotatably connected to the protruding end 912 near the pressure wheel 96 by a lifting spring 94. One end of the lifting spring 94 is connected to a connecting rod 95. The two sides of the connecting rod 95 are fixed on the base 4. The lifting spring 94 pulls the lifting guide plate 91 taut in the direction of the connecting rod 95. The lifting spring 94 and the cam structure 8 work together to form an elastic and mutually balanced connection structure, which ensures that the linkage between the lifting guide plate 91 and the cam structure 8 is more stable and smooth.

[0049] Reference Figure 14 The cam structure 8 includes a cam assembly 81, a slider 82, a slide rail 83, and a first power mechanism for the reciprocating movement of the cam assembly 81. The cam assembly 81 is composed of multiple sets of cams 811 corresponding to the lifting guide plate 91. (Refer to...) Figure 15 The cam 811 includes a double arc-shaped plate 811a, with annular protrusions 811c on both sides of the double arc-shaped plate 811a. A balance wheel 811b is fitted onto each protrusion 811c. By adding the balance wheel 811b, the mass of the cam 811 can be increased, improving its inertia and enabling the cam 811 to better push the lifting structure 9. A cam surface 811d is provided on the edge of the double arc-shaped plate 811a, and a pressing wheel 96 presses against the cam surface 811d. A cam connecting shaft 813 is fitted inside the cam 811. Multiple cams 811 are connected as one unit via the cam connecting shaft 813. The multiple cams 811 are installed at a predetermined angle using cam fixing screws 811e. The multiple cams 811 can be installed at different angles depending on the lifting structure 9 they abut against, thus enabling the cam 811 to lift and lower the lifting structure 9 in a specific sequence. The cam assembly 81 is connected to the cam connecting shaft 813 by cam supports 812 on both sides, and the cam connecting shaft 813 and the cam supports 812 are locked and fixed by locking screws 814. A slider 82 is also provided at the bottom of the cam support 812. The cam assembly 81 is slidably connected to the slide rail 83 through the slider 82. An integrally connected connecting plate 87 is provided between the cam supports 812. The first power mechanism includes a third servo motor 84 and a second concentric wheel 85 coaxially connected to the third servo motor 84. A second eccentric column 851 is provided on the second concentric wheel 85. A cam push rod 86 is rotatably provided on the second eccentric column 851. The cam push rod 86 is rotatably connected to the connecting plate 87. The third servo motor 84 moves the cam assembly 81 back and forth on the slide rail 83. The pressure wheel 96 abuts against the cam curved surface 811d. Therefore, the change of the arc surface of the cam curved surface 811d of the cam 811 forms a regular up and down movement.

[0050] Reference Figure 4 , Figure 5The weft yarn feeding mechanism 5 includes a weft yarn handle 51 and a weft hook 52. One end of the weft yarn handle 51 is rotatably connected to a first servo motor 56 via a shaft 53. The first servo motor 56 is mounted on a support plate 43 of the base 4. To better achieve the rotatable connection between the first servo motor 56 and the shaft 53, a connecting seat 58 is provided on the support plate 43. A bearing 57 is installed inside the connecting seat 58. The shaft 53 passes through the bearing 57 and is rotatably connected to the first servo motor 56. Thus, the first servo motor 56... 6 can rotate at a fixed angle to drive the weft aluminum hand 51 to swing back and forth. The weft hook 52 is connected to the other end of the weft aluminum hand 51. During the reciprocating swing of the weft aluminum hand 51, the weft hook 52 is driven to swing from one side of the machine base 4 to the other side of the machine base 4. At the end of the weft hook 52, there is a weft hole 521 for guiding the yarn. The weft yarn passes through the weft hole 521. During the reciprocating swing of the weft hook 52, the weft yarn is introduced into the weaving between the multiple warp threads interwoven by the upper and lower hemispheres of the frame 2.

[0051] During the weft yarn feeding process, to better ensure the stable swing of the weft hook 52, a tensioning mechanism 55 is connected to one end of the weft hook 52 of the feeding structure 5. The tensioning mechanism 55 includes a pull rope 553 connected to the weft hook 52. The pull rope 553 is connected to a tension spring 551 through a spring connecting end 552. The other end of the tension spring 551 is connected to the base plate 44 of the machine base 4 through the spring connecting end 552. In this embodiment, since the swing surface of the weft hook 52 is a horizontal plane and the mounting surface of the tension spring 551 is a vertical plane, the swing surface of the weft hook 52 and the mounting surface of the tension spring 551 are not on the same plane. To ensure that the tension spring 551 can better pass through the horizontal plane, a tensioning mechanism 55 is also connected to the base plate 44 of the machine base 4. Through the elastic stretching of the stretching 553 in conjunction with the back-and-forth swinging of the weft hook 52, a guide plate 431 is provided on the support plate 43 on the base 4. The guide plate 431 is provided with a limiting hole, and two oppositely arranged guide wheel seats 432 are provided on the support plate 43 at the rear of the guide plate 431. An opening is provided between the guide wheel seats 432, and a pull rope guide wheel 54 is rotatably arranged between the guide wheel seats 432. The pull rope 553 is positioned by passing through the limiting hole and is wound inside the pull rope guide wheel 54. The pull rope 553 forms a vertical direction through the pull rope guide wheel 54. Therefore, during the swinging process, the weft hook 52 is more stable and smoother due to the elastic stretching of the tension spring 551.

[0052] Reference Figure 9 , Figure 10 , Figure 11The knitting mechanism 6 includes a knitting needle holder 61 and a knitting needle 62. The knitting needle 62 includes a knitting needle bar 621, with a knitting needle hook 622 at its end. A needle retraction bar 623 rotates between the needle hook 622 and the knitting needle bar 621, forming an openable or closed structure. A limiting post 624 is provided on the side of the knitting needle bar 621 away from the needle retraction bar 623. The knitting needle holder 61 includes a first holder 611 and a cover plate 612. A push groove 613 is provided on the first holder 611, and a limiting groove 614 corresponding to the limiting post 624 is also provided in the push groove 613. The knitting needle bar 621 is movably disposed in the push groove 613 and positioned by the limiting groove 614. One end of the needle bar 621 is connected to a needle arm push rod 63, which is also partially located inside the push groove 613. After the needle arm push rod 63 is connected to the needle bar 621, a cover plate 612 is installed on one side of the first fixed seat 611 with the push groove 613. Thus, the cover plate 612 confines the needle arm push rod 63 and the needle bar 621 inside the push groove 613. The needle arm push rod 63 is rotatably connected to a push plate 64. The push plate 64 moves the needle 62 back and forth along the push groove 613 through the needle arm push rod 63. The back and forth movement of the needle 62 and the back and forth swinging motion of the weft hook 52 cooperate to realize the pulling and unwinding of the weft yarn by the needle 62, thus realizing the interlacing weft and warp yarns.

[0053] A second power mechanism for the reciprocating movement of the knitting needle 62 is also provided at one end of the push plate 64. The second power mechanism includes a motor 66 and a first concentric wheel 65 coaxially connected to the motor 66. A first eccentric column 651 is provided on the first concentric wheel 65. The first eccentric column 651 is rotatably connected to the push plate 64. The rotation of the motor 66 drives the knitting needle 62 to reciprocate along the push groove 613, thereby realizing the pulling and unpulling of the weft yarn by the knitting needle 62.

[0054] Reference Figure 3 , Figure 12The webbing anti-loosening mechanism 7 includes a guide rod assembly 71 and an anti-loosening rod assembly 72. The guide rod assembly 71 includes a first guide rod 711, a second guide rod 712, a third guide rod 713, and a fourth guide rod 714. The first guide rod 711, the second guide rod 712, the third guide rod 713, and the fourth guide rod 714 are connected to the machine base 4 in a Z-shape. The first guide rod 711 is rotatably mounted. The second guide rod 712 and the third guide rod 713 are rotatably connected to the machine base 4 via a one-way bearing 73. An anti-loosening rod assembly 72 is also provided between the fourth guide rod 714 and the third guide rod 713. The anti-loosening rod assembly 72 includes a first anti-loosening rod 72. The first and second anti-loosening rods 721 and 722 are rotatably connected to the base 4. A second servo motor 74 is provided on one side of either the first or second anti-loosening rod 721. A gear 75 is coaxially connected to each of the first and second anti-loosening rods 721 and 722 on the other side, and the two gears 75 mesh with each other. The rotation of the second servo motor 74 drives the anti-loosening rod assembly 72 to rotate synchronously but in opposite directions. The fourth guide rod 714 is connected to a pre-tightening adjustment structure, through which the gap between the fourth guide rod 714 and the second anti-loosening rod 722 can be adjusted. Figure 12 After the webbing 10 is woven, it is wound by the webbing anti-loosening mechanism 7. The webbing 10 makes two turns along the lower surface of the first guide rod 711 and around the outer surface of the second guide rod 712 and the third guide rod 713. The webbing 10 is led out between the first anti-loosening rod 721 and the second anti-loosening rod 722, and is pressed out of the outside through the gap between the second anti-loosening rod 722 and the fourth guide rod 714.

[0055] In this embodiment, by setting the webbing anti-loosening mechanism 7, the webbing 10 can be better ejected. The webbing 10 is guided and led out between the first anti-loosening rod 721 and the second anti-loosening rod 722 by the first guide rod 711, the second guide rod 712 and the third guide rod 713. Driven by the second servo motor 74, the first anti-loosening rod 721 and the second anti-loosening rod 722 squeeze and rotate to provide the power to pull out the webbing 10. Finally, the pressed webbing 10 is led out to the outside by the fourth guide rod 714. The webbing 10 passes through the first anti-loosening rod 711. The second anti-loosening rod 722, after being tightened, ensures that the subsequent webbing 10 generates a rebound force during the weaving process, thus pulling the woven webbing 10. Furthermore, the second guide rod 712 and the third guide rod 713, through the setting of a one-way bearing 73, rotate in the output direction of the webbing 10. The rebound force generated by the webbing 10 during the weaving process pulls on the second guide rod 712 and the third guide rod 713, so they will not rotate in the opposite direction, further improving the anti-loosening output of the webbing 10.

[0056] In this embodiment, a pre-tightening adjustment structure is also provided. This structure can adjust the gap between the fourth guide rod 714 and the second anti-loosening rod 722, thereby pressing the webbing 10 out of the belt by the fourth guide rod 714. The pre-tightening adjustment structure includes a connecting plate 77, a fixing block 78, and an adjusting assembly 76. One end of the connecting plate 77 is connected to the end of the fourth guide rod 714, and the middle part of the connecting plate 77 is rotatably connected to the fixing block 78. The other end of the connecting plate 77 is provided with an adjusting groove 771. (Refer to...) Figure 13 The adjusting assembly 76 includes two opposing first fixing posts 761, which are connected and fixed together by a second fixing post 762. Each first fixing post 761 has a sliding groove 767, and a first adjusting post 763 and a second adjusting post 764 are slidably connected between the two sliding grooves 767. An adjusting spring 766 is provided between the first adjusting post 763 and the second adjusting post 764. An adjusting screw 765 is provided in the middle of one of the second fixing posts 762, passing through the second fixing post 762 and threadedly connected to the second adjusting post 764. 3 has a connecting hole 768, and the adjusting groove 771 has a pin 772. The pin 772 is connected to the connecting hole 768 through the adjusting groove 771. When the adjusting screw 765 is rotated, the second adjusting column 764 moves and presses against the first adjusting column 763 through the adjusting spring 766. The first adjusting column 763 slides and drives the connecting plate 77 to swing around the fixed block 78 as the fulcrum. The fourth guide rod 714 elastically presses the exposed webbing 10 onto the surface of the second anti-loosening rod 722 and leads it out. Through the adjusting component 76, the fourth guide rod 714 adjustably presses the webbing 10 out of the second anti-loosening rod 722 and leads it out to the outside.

[0057] The above embodiments merely illustrate implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
