Description

Technical Field

[0001] This invention relates to the field of knitting machinery technology, and more specifically, to a two-color yarn scissor device and control method for a glove machine. Background Technology

[0002] With the upgrading of consumer demand, multi-colored gloves have gradually become the mainstream in the market. However, the motor-driven scissor devices commonly equipped on existing glove knitting machines are designed to only allow for the replacement and cutting of single-color yarns. Even with the addition of auxiliary yarn colors, they can only knit a maximum of two-color gloves. This limitation prevents glove knitting machines from meeting the market demand for at least three-color knitting, thus restricting product diversification and market competitiveness.

[0003] Therefore, it is necessary to improve the existing scissor mechanism to enable it to manage more colors of yarn, thereby enhancing the knitting capacity of the glove machine. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a two-color yarn scissor device and control method for a glove machine. Through innovative design of the mechanical structure, a set of scissor devices can manage two different colors of yarn at the same time, thereby supporting the glove machine to perform mixed weaving of at least three colors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-color yarn cutting device for a glove machine includes a cutting scissor base, a hooking assembly, a cutting scissor assembly, a first clamping assembly, and a second clamping assembly. The cutting scissor base is fixedly mounted on the cutting scissor frame shaft. The hooking assembly is used to hook the yarn and works in conjunction with the cutting scissor assembly to complete the cutting action. The first clamping assembly is used to selectively and continuously clamp or release a first type of yarn. The second clamping assembly works in conjunction with the cutting scissor assembly to clamp or release the yarn after each hooking and cutting. The clamping positions of the first and second clamping assemblies are staggered in the horizontal direction so that the first and second types of yarn can be clamped simultaneously without interfering with each other. The first clamping assembly maintains clamping on the first type of yarn when the second type of yarn enters the weaving state. By controlling the timing of the actions of the first and second clamping assemblies, independent clamping and switching of the first and second types of yarn can be achieved.

[0007] Furthermore, the hook assembly includes a fixed plate, a hook blade, and a pulling plate. The fixed plate is fixedly mounted on the scissor seat, and a first motor is mounted on the fixed plate. A rotating arm is mounted on the output shaft of the first motor. The rotating arm is movably connected to one end of the pulling plate. The hook blade slides up and down inside the scissor seat, and its tail is movably connected to the other end of the pulling plate, so that the hook blade completes one up and down movement for each rotation of the first motor.

[0008] Furthermore, the hook assembly also includes a first magnet mounted on the rotating arm and a first sensor, the first sensor being used to sense the first magnet to control the starting position of the hook blade.

[0009] Furthermore, the scissor assembly includes fixed scissors, movable scissors, an action plate, and a scissor shaft. The fixed scissors are fixedly mounted on the scissor base, and the scissor shaft movably passes through the scissor base and the fixed scissors. The movable scissors are fixedly mounted on the upper end of the scissor shaft, and the action plate is movably mounted on the fixed plate. Its lower end is movably connected to the tail of the hook blade and the other end of the pull plate. When the hook assembly is activated, the action plate synchronously drives the scissor shaft to rotate, thereby causing the movable scissors to rotate. The movable scissors and the fixed scissors work together to complete the cutting of the thread.

[0010] Furthermore, an actuating head is fixedly installed at the lower end of the scissor shaft, and a guide groove adapted to the end of the actuating head is provided on the actuating plate. The guide groove includes a vertical section and an inclined section connected to the vertical section. When the end of the actuating head moves between the vertical section and the inclined section, it drives the scissor shaft 31 to rotate.

[0011] Furthermore, a compression spring is fitted at the lower end of the scissor shaft, and the two ends of the compression spring abut against the actuating head and the scissor seat respectively to ensure that the movable scissors and the fixed scissors are in close contact.

[0012] Furthermore, the first wire clamping assembly includes a fixed base, a second motor, a rack, an upper wire clamping plate a, and a lower wire clamping plate a. The second motor is fixedly mounted on the fixed base, and a gear is mounted on the output shaft of the second motor. A mounting groove adapted to the rack is opened on one side of the fixed base. The rack is slidably connected in the mounting groove and meshes with the gear. The rack is connected to one end of the upper wire clamping plate a through a connecting plate. A notch for the hook head to pass through is opened at the other end of the upper wire clamping plate a. A long groove is opened in the middle of the upper wire clamping plate a. A scissor seat is screwed on after the first axial screw passes through the long groove of the upper wire clamping plate a and the lower wire clamping plate a, thus mounting the upper wire clamping plate a and the lower wire clamping plate a on the scissor seat. The upper wire clamping plate a can move relative to the lower wire clamping plate a along the direction of the long groove.

[0013] Furthermore, the first clamping assembly also includes a second magnet mounted on the rack and a second sensor, the second sensor being used to sense the second magnet to control the rotation of the second motor and determine the position of the rack.

[0014] Furthermore, the second wire clamping assembly includes an upper wire clamping piece b and a lower wire clamping piece b. The upper wire clamping piece b is fixed to the scissor shaft together with the movable scissors by a fixing screw to achieve synchronous rotation. The lower wire clamping piece b is mounted on the fixed scissors.

[0015] The present invention also provides a control method for a two-color yarn scissor device of a glove machine, comprising:

[0016] When the machine is started, the first type of yarn is clamped on the first clamping assembly, the second type of yarn is clamped on the second clamping assembly, and the auxiliary yarn is clamped on the auxiliary device. After the machine is started, the second motor rotates and drives the rack to move through the gear. The rack drives the upper clamping plate a to move horizontally through the connecting plate, releasing the first type of yarn. The second motor rotates in the opposite direction, so that the upper clamping plate a is reset and the first type of yarn enters the weaving state.

[0017] When it is necessary to switch from the first type of yarn to the second type of yarn for weaving, perform the following steps:

[0018] The second motor rotates, driving the upper clamping piece a to move so that its notch is directly above the head of the hook knife;

[0019] The first motor rotates, driving the hook knife to rise to hook the first type of yarn. At the same time, the movable scissors and the upper clamping plate b open. When the rotating arm reaches the highest point, the second type of yarn clamped by the second clamping assembly is completely released. The hook knife hooks the first type of yarn and begins to descend. The movable scissors and the upper clamping plate b close, cutting the first type of yarn and clamping it in the second clamping assembly.

[0020] The second motor rotates again, driving the upper clamping piece a to reset. During this process, the first type of yarn is simultaneously clamped by the first clamping assembly and the second clamping assembly, and the second type of yarn enters the weaving state.

[0021] When it is necessary to switch back to the first yarn for weaving, follow these steps:

[0022] The second motor does not operate, and the first wire clamping assembly maintains the clamping state on the first type of yarn.

[0023] The first motor rotates, and the hook blade rises to hook the second type of yarn that is being woven. During this process, the upper clamping plate b in the second clamping assembly opens and closes normally to release the clamped first type of yarn; the hook blade descends to cut the second type of yarn and is then clamped by the second clamping assembly.

[0024] The second motor rotates, driving the rack to move via gears. The rack moves the upper clamping piece a through the connecting plate, releasing the first type of yarn. The second motor rotates in the opposite direction, resetting the upper clamping piece a. At this time, the first type of yarn enters the weaving state.

[0025] When both the first yarn and the second yarn exit the weaving state and an auxiliary yarn is needed to enter the weaving state, the first yarn is held by the first yarn clamping component and the second yarn is held by the second yarn clamping component. At the same time, the first yarn is released by the second yarn clamping component, and both yarns are in a standby state.

[0026] When the first type of yarn is needed to participate in weaving again, the second motor rotates, driving the rack to move through the gears. The rack moves the upper clamping plate a through the connecting plate, releasing the first type of yarn. The second motor rotates in the opposite direction, causing the upper clamping plate a to reset. At the same time, the auxiliary device cuts and clamps the auxiliary yarn.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention achieves independent clamping and on-demand switching management of two different colored yarns through the coordinated operation of the first and second yarn clamping components. This enables the glove machine to support mixed weaving of at least three colors without adding complex mechanisms, resulting in a substantial upgrade in weaving varieties and better adapting to the market demand for multi-colored gloves.

[0029] 2. By dividing the work and cooperating of two sets of yarn clamping components, the present invention achieves the separation of "dynamic switching clamping" and "static holding clamping", so that each yarn can be reliably clamped or released during frequent color yarn switching, effectively avoiding the risk of yarn coming off or getting tangled during frequent switching.

[0030] 3. This invention makes the most of the existing mature structure. By adding the first wire clamping component and the second wire clamping component, a leapfrog improvement in functionality is achieved. The overall appearance and interface size of the device have not changed significantly, the cost increase is limited, and its assembly, debugging and maintenance methods are the same as the original technology, so the convenience of maintenance is fully preserved.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example: A two-color yarn scissor device for a glove machine, such as Figures 1-7 As shown, the device includes a scissor holder 1, a hook assembly, a scissor assembly, a first clamping assembly, and a second clamping assembly. The scissor holder 1 is fixedly mounted on the scissor frame shaft 10 of an existing glove machine, serving as the mounting base for the entire device. The hook assembly is used to hook the yarn and works in conjunction with the scissor assembly to complete the yarn cutting action. The first clamping assembly is used to selectively and continuously clamp or release a first type of yarn. The second clamping assembly works in conjunction with the scissor assembly to clamp or release the yarn after each hooking and cutting of the current yarn. The clamping positions of the first and second clamping assemblies are staggered in the horizontal direction so that the first and second types of yarn can be clamped simultaneously without interfering with each other, and the first clamping assembly maintains clamping of the first type of yarn when the second type of yarn enters the weaving state. By controlling the timing of the actions of the first and second clamping assemblies, independent clamping and switching of the first and second types of yarn can be achieved. It should be noted that the glove machine has one auxiliary yarn that can participate in weaving. The auxiliary yarn is used in conjunction with the auxiliary device, which is existing technology. This device is used to manage two other types of yarn that can be switched colors (the first type of yarn and the second type of yarn).

[0041] like Figures 1-4As shown, the hook assembly includes a fixed plate 19, a first motor 22, a rotating arm 21, a pulling plate 20, a hook blade 2, and a hook blade cover plate 35. The fixed plate 19 is fixedly mounted on the scissor base 1, and the first motor 22 is fixedly mounted on the fixed plate 19. The output shaft of the first motor 22 is fixedly mounted on the rotating arm 21. One end of the rotating arm 21 is movably connected to the pulling plate 20, and the other end of the pulling plate 20 is movably connected to the tail of the hook blade 2 and the action plate 17 in the scissor assembly. The hook blade 2 is placed in a corresponding vertical groove in the scissor base 1 and can slide up and down. Its outer side is limited by the hook blade cover plate 35 to prevent it from coming off. When the first motor 22 rotates once, the rotating arm 21 drives the hook blade 2 to complete one up-and-down movement via the pulling plate 20.

[0042] Preferably, the hook assembly also includes a first magnet 14 and a first sensor 23. The first magnet 14 is embedded in the rotating arm 21, and the first sensor 23 is fixedly installed on the fixing plate 19. The first sensor 23 is used to sense the first magnet 14 to control the starting position of the hook 2 to be at the bottom.

[0043] like Figures 2-5 As shown, the scissor assembly includes a fixed scissor 30, a movable scissor 29, an actuating plate 17, and a scissor shaft 31. The scissor shaft 31 is movably inserted into a shaft hole in the scissor base 1, allowing free rotation. The fixed scissor 30 is fixedly mounted on the scissor base 1, and has a through hole for the scissor shaft 31 to pass through. The movable scissor 29 is fixed to the upper end of the scissor shaft 31 by a fixing screw 34 and can rotate with the scissor shaft 31. The blade contact surfaces of the movable scissor 29 and the fixed scissor 30 are angled, so that when they are closed, they make line contact rather than surface contact, thereby enhancing the shearing force and ensuring that the yarn can be cut smoothly.

[0044] The action plate 17 has a guide groove 40 of a specific shape, which is movably assembled on the fixed plate 19 by the second axis screw 18 and the transition screw 38, and the lower end is movably connected to the tail end of the hook knife 2 and the other end of the pull plate 20 by special screws, so as to move in conjunction with the hook assembly.

[0045] Furthermore, an actuating head 33 is fixedly installed at the lower end of the scissor shaft 31. The end of the actuating head 33 is provided with an actuating round head, which extends into the guide groove 40 of the actuating plate 17. The movement of the round head within the guide groove 40 realizes the rotation of the movable scissors 29. Specifically, the guide groove 40 includes a vertical section 401 and an inclined section 402. The inclined section 402 is located above the vertical end and is connected to the vertical section 401. During the up-and-down movement of the actuating plate 17 driven by the hook assembly, the end of the actuating head 33 moves along the guide groove 40. When the end moves from the vertical section 401 into the inclined section 402 or in the opposite direction, it drives the scissor shaft 31 to rotate, thereby realizing the rotation of the movable scissors 29.

[0046] Furthermore, a compression spring 32 is fitted at the lower end of the scissor shaft 31. The two ends of the compression spring 32 abut against the corresponding holes on the actuating head 33 and the scissor seat 1, respectively. The compression spring 32 provides a downward preload to the scissor shaft 31, so that the movable scissors 29 always tends to close towards the fixed scissors 30, ensuring that the two are in close contact.

[0047] When the first motor 22 drives the hook 2 to move upward, the action plate 17 is moved, and its guide groove 40 pushes the action head 33. The action head 33 is pushed from the inclined section 402 of the guide groove 40 to the vertical section 401, thereby causing the scissor shaft 31 to rotate and the movable scissors 29 to open. When the hook 2 descends, the action head 33 is pushed from the vertical section 401 to the inclined section 402, thereby causing the scissor shaft 31 to rotate and the movable scissors 29 to close and reset, completing the wire cutting action.

[0048] like Figures 2-4 As shown, the first wire clamping assembly includes a fixed base 16, a second motor 15, a rack 12, an upper wire clamping plate a4, and a lower wire clamping plate a6. The fixed base 16 is fixed to the open bending plate 3 and, through the open bending plate 3, to the scissor seat 1. The second motor 15 is fixedly mounted on the fixed base 16, and a gear 13 is mounted on its output end. A mounting groove adapted to the rack 12 is provided on one side of the fixed base 16. The rack 12 is slidably disposed in the mounting groove and meshes with the gear 13.

[0049] Preferably, a pressure plate 11 is installed on the fixing seat 16, and the pressure plate 11 limits the two sides of the rack 12 to prevent the rack 12 from falling out of the mounting groove.

[0050] Preferably, a second magnet 36 is embedded in the rack 12, and a sensor mounting plate 8 is installed on the mounting base 16. A sensor is installed on the sensor mounting plate 8. The sensor is used to sense the second magnet 36 to determine the stroke of the rack 12, thereby controlling the rotation and stopping of the second motor 15. The second sensor 7 is lit when it is in the zero position state.

[0051] A connecting plate 9 is mounted on the rack 12 and is connected to one end of the upper clamping piece a4 through the connecting plate 9. The other end of the upper clamping piece a4 has a notch 39 for the head of the hook knife 2 to pass through. The middle of the upper clamping piece a4 has a long groove 41 along its length direction. Two first shaft screws 5 pass through the long groove 41 and the lower clamping piece a6 and are threaded to the scissor seat 1, so that the upper clamping piece a4 can move without too much gap along the direction of the long groove 41 and cooperate with the lower clamping piece a6 to clamp or release the yarn.

[0052] like Figures 2-5As shown, the second yarn clamping assembly includes an upper clamping plate b26 and a lower clamping plate b27. The upper clamping plate b26 is fixed to the scissor shaft 31 along with the movable scissors 29 by the same fixing screw 34, thus rotating synchronously with the movable scissors 29. The lower clamping plate b27 is located below the upper clamping plate b26 and is mounted on the fixed scissors 30. The upper clamping plate b26 and the lower clamping plate b27 cooperate to clamp the yarn.

[0053] To ensure flexible and non-interfering movement of the stacked components, multiple washers are installed in the device. Specifically: Washer C28 is placed between the fixed scissors 30 and the lower clamping plate B27, and its thickness is slightly greater than that of the movable scissors 29 to prevent the movable scissors 29 from getting stuck when rotating. Washer B25 is placed between the lower clamping plate B27 and the lower clamping plate A6, and its thickness is greater than that of the upper clamping plate B26 to prevent the upper clamping plate B26 from getting stuck when rotating. Washer A24 is located between the lower clamping plate A6 and the scissor seat 1, and its thickness is set to match the sum of the thicknesses of washers B25, B27, C28, and the pressed part of the fixed scissors 30, thereby ensuring the flatness and uniform force distribution of the entire wire clamping assembly mounting surface.

[0054] This embodiment also provides a control method for a two-color yarn scissor device in a glove machine. This method manages two different colored yarns and supports their mixed weaving with auxiliary yarns during the glove machine weaving process. Specifically:

[0055] Initial state confirmation

[0056] Before the device is started, the control system checks whether the first sensor 23 is lit, confirming that the hook 2 and the action plate 17 are in the lowest position; at the same time, it checks whether the second sensor 7 is lit, confirming that the upper clamping plate a4 is in the zero position (its end notch 39 is not directly above the hook 2). At this time, the movable scissors 29 and the fixed scissors 30, and the upper clamping plate b26 and the lower clamping plate b27 are both in a closed state. Then, by manually passing the first type of yarn through its corresponding shuttle device and clamping it on the first clamping assembly, passing the second type of yarn through its corresponding shuttle device and clamping it on the second clamping assembly, and passing the auxiliary yarn through its corresponding shuttle device and clamping it on the auxiliary device.

[0057] After the machine is turned on, the shuttle device corresponding to the first type of yarn is activated by the glove machine's electronic control, causing the knitting head to drive the first type of yarn to participate in knitting. After the knitting needle hooks the first type of yarn, the second motor 15 rotates, driving the rack 12 to move through the gear 13. The rack 12 drives the upper clamping plate a4 to move horizontally through the connecting plate 9, thus releasing the first type of yarn. The second motor 15 then rotates in the opposite direction, causing the upper clamping plate a4 to reset.

[0058] Switch to the second type of yarn weaving

[0059] According to the glove knitting requirements, when the first type of yarn stops knitting and the second type of yarn is used instead, the following steps should be performed:

[0060] In step A1, the second motor 15 rotates and drives the rack 12 to move through the gear 13. The rack 12 drives the upper clamping piece a4 to move horizontally through the connecting plate 9 until the notch 39 at its end is exactly above the head of the hook knife 2. At this time, the shuttle device corresponding to the first type of yarn exits the working state, and the shuttle device corresponding to the second type of yarn is driven by the knitting machine head and enters the working state.

[0061] In step A2, the first motor 22 rotates, and the rotating arm 21 drives the hook 2 to move upward through the pull plate 20. The head of the hook 2 passes through the notch 39 of the upper clamping piece a4 to hook the first type of yarn. At the same time, the rise of the hook 2 drives the action plate 17 to move. The guide groove 40 on the action plate 17 causes the action head 33 to swing, and the scissor shaft 31 rotates, thereby opening the movable scissors 29 and the upper clamping piece b26 simultaneously.

[0062] In step A3, when the rotating arm 21 reaches its highest point, the second type of yarn clamped by the second yarn clamping assembly is completely released, the hook 2 hooks the first type of yarn and begins to descend, and the movable scissors 29 and the upper yarn clamping plate b26 close accordingly; during the descent, the hooked first type of yarn is cut by the movable scissors 29 and the fixed scissors 30, and is simultaneously clamped by the upper yarn clamping plate b26 and the lower yarn clamping plate b27 that have just closed.

[0063] In step A4, the second motor 15 rotates again, driving the rack 12 and the upper clamping plate a4 to reset until the second sensor 7 lights up and the upper clamping plate a4 returns to the zero position. During this translation process, the first type of yarn, which was originally clamped by the second clamping assembly, is clamped by the upper clamping plate a4 and the lower clamping plate a6. That is, the first type of yarn is simultaneously and firmly clamped by two sets of clamping assemblies. At this time, the second type of yarn is fully in the weaving state.

[0064] Switch to the first type of yarn weaving

[0065] When the first type of yarn is needed again for weaving, the specific steps are as follows:

[0066] In step B1, the second motor 15 does not operate, and the upper clamping plate a4 in the first clamping assembly remains at the zero position, continuing to clamp the first type of yarn; at this time, the shuttle device corresponding to the second type of yarn exits the working state, and the shuttle device corresponding to the first type of yarn is driven into the working state by the knitting head.

[0067] In step B2, the first motor 22 rotates and the hook 2 rises again to hook the second type of yarn that is being woven. During this process, the upper clamping plate b26 in the second clamping assembly will open and close normally to release the clamped first type of yarn.

[0068] In step B3, the hook 2 descends, cutting the newly hooked second type of yarn, which is then clamped by the upper clamping plate b26 and the lower clamping plate b27. At this time, the above release action is repeated, the second motor 15 rotates, and drives the rack 12 to move through the gear 13. The rack 12 drives the upper clamping plate a4 to move horizontally through the connecting plate 9, thus releasing the first type of yarn. The second motor 15 rotates in the opposite direction, causing the upper clamping plate a4 to reset. At this time, the first type of yarn is fully in the weaving state.

[0069] Switch to auxiliary yarn knitting

[0070] When both the first and second yarns need to exit the weaving state and an auxiliary yarn needs to enter the weaving state, the glove machine's auxiliary device, in conjunction with the corresponding shuttle device, uses an electronic control command to put the auxiliary yarn into the weaving state. At this time, the first yarn is reliably held by the first yarn clamping assembly, the hook 2 hooks the second yarn and is reliably held by the second yarn clamping assembly, and the first yarn is released by the second yarn clamping assembly. Both yarns are in a standby state.

[0071] When the first type of yarn is needed to participate in weaving again, the shuttle device corresponding to the first type of yarn is activated by the glove machine's electronic control, causing the knitting head to drive the first type of yarn to participate in weaving. After the knitting needles hook the first type of yarn and begin weaving, the second motor 15 rotates, driving the rack 12 to move via the gear 13. The rack 12, through the connecting plate 9, drives the upper clamping plate a4 to move horizontally, releasing the first type of yarn. The second motor 15 then rotates in the opposite direction, causing the upper clamping plate a4 to reset. Simultaneously, the glove machine's auxiliary device cuts and clamps the auxiliary yarn.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.

10. A control method for the two-color yarn scissor device of a glove machine as described in any one of claims 1-9, characterized in that, include: When the machine is turned on, the first type of yarn is clamped on the first clamping assembly, the second type of yarn is clamped on the second clamping assembly, and the auxiliary yarn is clamped on the auxiliary device. After the machine is turned on, the second motor (15) rotates and drives the rack (12) to move through the gear (13). The rack (12) drives the upper clamping plate a (4) to move horizontally through the connecting plate (9) to release the first type of yarn. The second motor (15) rotates in the opposite direction to reset the upper clamping plate a (4), and the first type of yarn enters the weaving state. When it is necessary to switch from the first type of yarn to the second type of yarn for weaving, perform the following steps: The second motor (15) rotates, driving the upper clamping piece a (4) to move so that its notch (39) is located directly above the head of the hook knife (2); The first motor (22) rotates, driving the hook (2) to rise to hook the first type of yarn, while the movable scissors (29) and the upper clamping plate b (26) open in conjunction; when the rotating arm (21) reaches the highest point, the second type of yarn clamped by the second clamping assembly is completely released, the hook (2) hooks the first type of yarn and begins to descend, the movable scissors (29) and the upper clamping plate b (26) close, cutting the first type of yarn and clamping it in the second clamping assembly; The second motor (15) rotates again, driving the upper clamping piece a (4) to reset. During this process, the first type of yarn is simultaneously clamped by the first clamping assembly and the second clamping assembly, and the second type of yarn enters the weaving state. When it is necessary to switch back to the first yarn for weaving, follow these steps: The second motor (15) does not operate, and the first clamping assembly maintains the clamping state on the first type of yarn; The first motor (22) rotates, and the hook (2) rises to hook the second type of yarn that is being woven. During this process, the upper clamping plate b (26) in the second clamping assembly opens and closes normally to release the clamped first type of yarn; the hook (2) descends to cut the second type of yarn and is clamped by the second clamping assembly. The second motor (15) rotates and drives the rack (12) to move through the gear (13). The rack (12) drives the upper clamping piece a (4) to move horizontally through the connecting plate (9) to release the first type of yarn. The second motor (15) rotates in the opposite direction to reset the upper clamping piece a (4). At this time, the first type of yarn enters the weaving state. When both the first yarn and the second yarn exit the weaving state and an auxiliary yarn is needed to enter the weaving state, the first yarn is held by the first yarn clamping component and the second yarn is held by the second yarn clamping component. At the same time, the first yarn is released by the second yarn clamping component, and both yarns are in a standby state. When the first type of yarn is needed to participate in weaving again, the second motor (15) rotates and drives the rack (12) to move through the gear (13). The rack (12) drives the upper clamping piece a (4) to move through the connecting plate (9) to release the first type of yarn. The second motor (15) rotates in the opposite direction to reset the upper clamping piece a (4). At the same time, the auxiliary device cuts and clamps the auxiliary yarn.
