Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a yarn weaving device. Background Technology

[0002] In the textile industry, the precision and efficiency of yarn weaving directly determine the quality grade and production efficiency of textiles. As the core production equipment, the rationality of the structural design of the yarn weaving device has a decisive impact on the weft insertion positioning accuracy, the stability of the mechanism operation, and the continuity of processing.

[0003] Traditional textile equipment often uses a single slide rail or gear transmission structure to move the yarn carrier. Its positioning error is typically greater than 0.5mm, far exceeding the precision standards required for high-end knitted fabric production. For example, although some flat knitting machines have reduced the knitting speed error rate to ±3% through electronic control system optimization, the lack of a bidirectional precision drive mechanism in the weft insertion mechanism during complex pattern knitting makes the yarn's movement trajectory in the X and Y axes prone to deviation, leading to defects such as misaligned fabric texture and uneven density. This positioning lag caused by mechanical inertia is particularly pronounced in high-speed knitting scenarios, further exacerbating the product defect rate.

[0004] Secondly, the yarn weft insertion assembly and the beat-up assembly are often designed as separate units, lacking a precise positional matching reference. After the weft insertion assembly completes yarn positioning, the beat-up components (such as beat-up needles and beat-up rollers) need to be calibrated using an additional adjustment mechanism. This not only prolongs the processing cycle but also easily leads to uneven beat-up force due to mechanical backlash. Furthermore, some devices have transmission delay issues in their drive systems. For example, belt-driven weft insertion mechanisms are prone to yarn vibration during start-up and stop, further reducing the synchronization of weft insertion and beat-up actions and affecting the continuity of the weaving operation.

The frame assembly serves as an overall support structure, with a square frame providing a stable mounting reference. A first ball screw drive component provides a power source for the yarn weft insertion assembly in a first direction (e.g., the X-axis direction). A pair of first slide rails parallel to the drive component define the movement trajectory of the yarn weft insertion assembly, ensuring its straightness and stability in the X-axis direction. A base plate is simultaneously mounted on the first slide rail and the first ball screw drive component via a sliding connection structure (e.g., a slider engaging with a slide rail, or a screw nut engaging with a screw) to achieve power transmission.

[0020] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] like Figure 1-7 As shown, this utility model embodiment provides a yarn weaving device, which includes a frame assembly 1, a yarn weft insertion assembly 2, and a weft beating processing assembly 3, wherein: The frame assembly 1 includes a square frame 11, a first ball screw drive component 12 and a first slide rail 13. The first ball screw drive component 12 is horizontally inserted and connected to the middle of the square frame 11. A pair of first slide rails 13 are installed on the upper surface of the square frame 11 and are arranged parallel to the first ball screw drive component 12. The yarn weft insertion assembly 2 includes a base plate 21, a second ball screw drive component 22, and a clamping and positioning module 23. The base plate 21 is slidably connected to the top of a pair of first slide rails 13 and the first ball screw drive component 12. The second ball screw drive component 22 is mounted on the upper surface of the base plate 21. The first ball screw drive component 12 is adapted to drive the base plate 21 to move along a first direction on the first slide rails 13. The second ball screw drive component 22 is arranged perpendicularly to the first ball screw drive component 12, and the second ball screw drive component 22 is adapted to drive the clamping and positioning module 23 to move along a second direction on the base plate 21.

[0022] The weft insertion processing component 3 is installed on one side of the square frame 11, and the weft insertion processing component 3 and the clamping and positioning module 23 are both located on the same side of the second ball screw drive component 22; the weft insertion processing component 3 is suitable for completing the yarn weaving operation under the action of the yarn weft insertion component 2.

[0023] In this embodiment, the frame assembly 1 serves as an overall support structure, wherein the square frame 11 is used to provide a stable mounting reference, the first ball screw drive component 12 is used to provide a power source in a first direction (e.g., the X-axis direction) for the yarn weft insertion assembly 2, and a pair of first slide rails 13 parallel to the drive component define the movement trajectory of the yarn weft insertion assembly 2, ensuring the straightness and stability of its movement in the X-axis direction.

[0024] The base plate 21 is simultaneously mounted on the first slide rail 13 and the first ball screw drive component 12 through a sliding connection structure (such as the slider cooperating with the slide rail, and the screw nut cooperating with the screw) to realize power transmission; the second ball screw drive component 22 is mounted on the base plate 21 perpendicular to the first ball screw drive component 12 (for example, in the Y-axis direction), and its power output end is connected to the clamping and positioning module 23, so that the clamping and positioning module 23 can move on the base plate 21 along the Y-axis direction; the clamping and positioning module 23 is used to clamp the yarn (or yarn carrier) and realize the weft insertion positioning of the yarn through bidirectional movement of the X-axis and Y-axis.

[0025] The weft insertion processing component 3 is installed on one side of the square frame 11 and on the same side as the clamping and positioning module 23. This ensures that after the yarn weft insertion component 2 completes the weft insertion and positioning, the weft insertion components (such as weft insertion needles and weft insertion rollers) can directly act on the positioned yarn to realize the weaving operation.

[0026] Specifically, please refer to Figure 4 As shown, in one embodiment of this utility model, the first ball screw drive component 12 includes a first drive motor 121, a first ball screw 122, and a sliding seat 123. The sliding seat 123 is threadedly connected to the first ball screw 122. The first drive motor 121 is fixedly mounted on the outside of the square frame 11 through a first motor mounting bracket 1211. The first ball screw 122 is rotatably mounted on the square frame 11 through a bearing seat 124, and one end extends out and is fixedly connected to the output shaft of the first drive motor 121 through a first coupling 125. The top of the sliding seat 123 is fixedly connected to the bottom of the base plate 21.

[0027] In this embodiment, the first drive motor 121 is triggered to run by a start control signal, and the motor output shaft rotates, converting electrical energy into rotational mechanical energy. The rotational power of the motor output shaft is transmitted to the first ball screw 122 through the first coupling 125. The first ball screw 122 rotates along its own axis under the support of the bearing seat 124. The rotational motion of the first ball screw 122 is converted into the linear motion of the sliding seat 123 through the screw nut thread pair. Since the sliding seat 123 is fixedly connected to the base plate 21, and the base plate 21 is slidably connected to the first... On a slide rail 13 (which limits the direction of movement of the base plate), the sliding seat 123 cannot rotate synchronously with the lead screw, but can only make directional linear motion along the axis of the lead screw (X-axis); the sliding seat 123 drives the base plate 21 and the yarn weft insertion assembly 2 to move along the first slide rail 13 until the preset weft insertion position is reached, thus completing the positioning in the first direction; if the position needs to be adjusted, the reciprocating movement of the sliding seat 123 can be achieved by controlling the forward and reverse rotation of the first drive motor 121 (changing the direction of rotation of the lead screw), thereby adjusting the position of the yarn weft insertion assembly 2.

[0028] Specifically, please refer to Figure 4 As shown, in one embodiment of the present invention, the first slide rail 13 includes a first slide bar 131 and a first slider 132, with the first slider 132 slidably mounted on the first slide bar 131.

[0029] In this embodiment, the first slide rail 13 serves as a guide and constraint mechanism for the movement of the yarn weft insertion assembly 2 in the first direction (X-axis). In conjunction with the first ball screw drive unit 12, it ensures the straightness, stability, and load-bearing capacity of the movement of the base plate 21 and the yarn weft insertion assembly 2.

[0030] Specifically, please refer to Figure 5 , 6 As shown, in one embodiment of this utility model, the second ball screw drive component 22 includes a support base 221, a second ball screw 222, and a second drive motor 223. Two support seats 221 are fixedly installed in parallel on the upper surface of the base plate 21. The second ball screw 222 is rotatably supported on the support seats 221. The second drive motor 223 is installed on one side of the base plate 21 through the second motor mounting bracket 2231. One end of the second ball screw 222 extends out of the support seat and is fixedly connected to the output shaft of the second drive motor through the second coupling.

[0031] In this embodiment, after the first ball screw drive component 12 completes the initial positioning of the base plate 21 in the X-axis direction, the second ball screw drive component 22 is in standby mode, and the clamping and positioning module 23 is located at the initial position of the second ball screw 222. The second drive motor 223 starts, and the motor output shaft rotates, converting electrical energy into rotational mechanical energy. The rotational power is transmitted to the second ball screw 222 through the second coupling 224, avoiding jamming or stress concentration during power transmission and ensuring smooth rotation of the screw. The second ball screw 222 rotates along its own axis under the constraint of the two support seats 221. Since the clamping and positioning module 23 is connected to the screw through the threaded pair, and the base plate 21 has been limited to displacement in the X-axis direction by the first slide rail 13, the clamping and positioning module 23 cannot rotate synchronously with the screw and can only make directional linear movements along the screw axis (Y-axis). When the clamping and positioning module 23 moves to the preset Y-axis positioning position, the second drive motor 223 stops running. The self-locking characteristics of the screw and the threaded pair (or the motor brake function) stably lock the clamping and positioning module 23 in the target position, completing the precise positioning in the second direction and providing a two-dimensional (XY) positioning reference for subsequent weft insertion operations. After the weft insertion operation is completed, the second drive motor 223 reverses and drives the clamping and positioning module 23 to reset along the Y-axis through the above transmission path, preparing for the next cycle.

[0032] Specifically, please refer to Figure 5 , 6 As shown, in one embodiment of this utility model, the clamping and positioning module 23 includes a second lead screw nut 231, a guide rail protective seat 232, a clamp 233, and a double-rod pneumatic cylinder 234. The second lead screw nut 231 is slidably connected to the second ball screw 222, the guide rail protective seat 232 is connected to the second lead screw nut 231, the clamp 233 is installed on the guide rail protective seat 232 and close to the weft punching processing component 3, the double-rod pneumatic cylinder 234 is vertically connected to the guide rail protective seat 232, and the piston rod of the double-rod pneumatic cylinder 234 is fixedly connected to the top of the clamp 233. The double-rod pneumatic cylinder 234 is suitable for driving the clamp 233 to move.

[0033] In the initial state, the clamping and positioning module 23 is in the initial position on the Y-axis along with the second ball screw 222, the piston rod of the double-rod pneumatic cylinder 234 extends, and the clamp 233 is in the open state. The yarn supply mechanism delivers the yarn to be braided to the clamping area of ​​the clamp 233. The control system triggers the double-rod pneumatic cylinder 234 to ventilate, the piston rod retracts, and the clamp 233 closes, achieving flexible clamping of the yarn (the clamping force is adjusted by air pressure to avoid excessive tightness that damages the yarn or excessive looseness that causes the yarn to slip off). The first ball screw drive component 12 drives the base plate 21 to move along the X-axis, driving the clamping and positioning module 23 and the clamped yarn to complete the initial positioning in the X-axis direction; then the second ball screw drive component 22 starts, driving the guide rail protection seat 232 and the clamp 233 to move along the Y-axis through the second screw nut 231, completing the precise positioning of the yarn in the XY plane. After positioning is completed, the weft-beating processing component 3 is activated to weft-beat the positioned yarn. During this process, the double-rod pneumatic cylinder 234 keeps the piston rod in a retracted state, and the clamp 233 continuously and stably holds the yarn to prevent displacement or detachment due to the weft-beating force. After a single weft-beating cycle is completed, the double-rod pneumatic cylinder 234 reverses airflow, the piston rod extends, and the clamp 233 opens to release the yarn. Subsequently, the second ball screw drive component 22 and the first ball screw drive component 12 reset sequentially, driving the clamping and positioning module 23 back to its initial position, ready for the next yarn clamping and positioning cycle.

[0034] Specifically, please refer to Figure 6 As shown, in one embodiment of this utility model, the clamping and positioning module 23 further includes a second slide rail 235 fixedly installed on the upper surface of the base plate 21. The second slide rail 235 is arranged parallel to and perpendicular to the second ball screw 222. The second slide rail 235 includes a second slide bar 2351 and a second slider 2352. The bottom of the second slide bar 2351 is connected to the base plate 21, the second slider 2352 is slidably installed on the second slide bar 2351, and the top of the second slider 2352 is fixedly connected to the bottom of the guide rail protective seat 232.

[0035] In this embodiment, the bottom of the second slide bar 2351 is fixedly connected to the base plate 21, and its length matches the effective stroke of the second ball screw 222, ensuring that the movement range of the clamping and positioning module 23 covers the entire working stroke in the Y-axis direction. The second slide bar 2351 is made of high-precision straight profile (such as hardened and ground alloy steel), and its parallelism with the second ball screw 222 must be guaranteed (error ≤ 0.01mm / m) to provide a precise straight reference for the sliding of the slider. The second slider 2352 is slidably mounted on the second slide bar 2351, and its top is rigidly connected to the bottom of the guide rail protective seat 232 (such as bolt fastening). The rigid connection between the slider and the protective seat ensures that the guiding constraint is directly transmitted to the entire clamping module, avoiding skewing or shaking when the module moves. The second slide rail 235 is arranged parallel to the second ball screw 222, forming a drive on one side and a guide on the other. Power is transmitted through the second screw nut 231 and the trajectory is constrained by the second slider 2352. The two work together to realize the directional linear movement of the clamping and positioning module 23 along the Y-axis, while bearing the weight of the module itself (guide rail protection seat 232, clamp 233, double rod pneumatic cylinder 234) and the yarn clamping load, and dispersing the radial force on the second ball screw 222.

[0036] Specifically, please refer to Figure 7 As shown, in one embodiment of this utility model, the weft insertion processing assembly 3 includes a motor mounting base 31, a brushless DC motor 32, a rotating shaft 33, and a yarn disc 34. The motor mounting base 31 is connected to the square frame 11. The brushless DC motor 32 is horizontally mounted on the top of the motor mounting base 31. The rotating shaft 33 is connected to the output shaft of the brushless DC motor 32. The yarn disc 34 is sleeved and mounted on the end of the rotating shaft 33 away from the brushless DC motor 32. The brushless DC motor 32 is suitable for driving the yarn disc 34 to rotate.

[0037] Initially, the brushless DC motor 32 is in standby mode, the yarn tray 34 is stationary, and the clamping and positioning module 23 carries the yarn to complete precise positioning in the XY plane, with the yarn within the working range of the yarn tray 34 (e.g., between the teeth / grooves on the outer circumference of the yarn tray). When the brushless DC motor 32 starts, the motor output shaft rotates, converting electrical energy into rotational mechanical energy. According to weaving requirements (e.g., weaving density, pattern type), the motor can be adjusted to a preset speed and maintain a stable speed. The rotational power of the motor output shaft is transmitted to the yarn tray 34 through the rotating shaft 33, and the yarn tray 34 rotates synchronously with the rotating shaft 33. Since the yarn tray 34 and the positioned yarn are in a preset relative position, the rotating yarn tray applies periodic pressure to the yarn through the outer circumferential structure (e.g., weft insertion teeth), compacting the yarn to the weaving base, while simultaneously achieving the interlacing of adjacent yarns. After a single weft insertion operation is completed (as set according to the weaving cycle), the brushless DC motor 32 can pause or maintain low-speed rotation, and the clamping and positioning module 23 releases the yarn and resets, preparing for the next weft insertion. For continuous weaving, the motor rotates steadily and continuously, with the weft insertion assembly and the weft insertion assembly working in tandem to achieve continuous interlacing. During weaving, the brushless DC motor 32 can dynamically adjust its speed through the control system according to the yarn type (such as thickness and material) or the requirements of the weaving pattern, ensuring that the weft insertion force matches the interlacing rhythm and preventing yarn breakage or uneven weaving density.

[0038] Specifically, please refer to Figure 4 , 6 As shown, in one embodiment of the present invention, a first micro limit switch 14 is connected to the end of the first slide rail 13, and a second micro limit switch 236 is connected to the end of the second slide rail 235.

[0039] Therefore, the first miniature limit switch 14 is fixed to the end of the first slide rail 13 (including the initial position end and the travel limit end), precisely aligned with the movement trajectory of the first slider 132; the second miniature limit switch 236 is fixed to the end of the second slide rail 235, aligned with the movement trajectory of the second slider 2352. The installation height of the limit switches must be adapted to the side / end face of the slider to ensure reliable triggering when the slider moves to the limit position.

[0040] The working process of this device is as follows: In the initial state, the base plate 21 of the yarn weft insertion assembly 2 is located at the initial position of the first slide rail 13, the clamping and positioning module 23 is located at the initial position of the second ball screw drive component 22, and the weft insertion processing assembly 3 is in standby state.

[0041] The clamping and positioning module 23 clamps the yarn to be woven, and the first ball screw drive component 12 is started. Through the screw nut, the base plate 21 is moved along the first slide rail 13 (X-axis direction) to the preset weft insertion position, so as to achieve the initial positioning of the yarn in the X-axis direction.

[0042] The second ball screw drive component 22 is activated, driving the clamping and positioning module 23 to move along the Y-axis, adjusting the position of the yarn in the Y-axis direction, and finally achieving precise positioning of the yarn in the weaving plane (XY plane).

[0043] After the yarn is positioned, the weft insertion processing component 3 is activated. The positioned yarn is compacted and interwoven by the weft insertion component to complete a single weft insertion operation and form a woven structure.

[0044] After the weft insertion is completed, the clamping and positioning module 23 releases the yarn, and the second ball screw drive component 22 and the first ball screw drive component 12 are reset in sequence, driving the clamping and positioning module 23 and the base plate 21 back to the initial position, ready for the next weft insertion-weft insertion cycle, and repeating the above steps to achieve continuous weaving.

[0045] The present invention has been disclosed above, but the scope of protection of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of the present invention.
