Description

Technical Field

[0001] This invention relates to the field of specialized equipment for the textile and light industry, and in particular to a weft feeding device. Background Technology

[0002] Elastic webbing is widely used in industries such as apparel, medical, and sporting goods, and its production quality directly affects the comfort, durability, and aesthetics of the products. In the production process of elastic webbing, the linear speed of the weft yarn is a crucial parameter, directly determining the width, appearance, and texture of the webbing. Ensuring a uniform weft yarn speed is a key task in the production process to guarantee the stability and high quality of webbing production.

[0003] In the production of elastic webbing, the loom manufactures the webbing through the interlacing of warp and weft yarns. Uneven weft yarn speed directly affects the width and appearance of the webbing. Specifically, when the weft yarn speed fluctuates, the width of the webbing becomes unstable, potentially leading to irregular shapes or dimensional deviations in the finished product. Furthermore, fluctuations in weft yarn speed can also cause changes in the width, appearance, and texture of the webbing, affecting its softness, smoothness, and even reducing its strength. Changes in weft yarn tension are also a crucial factor affecting webbing quality. When the weft yarn speed is unstable, the tension of the webbing also fluctuates, affecting its tightness and elasticity, resulting in a less than expected overall performance. Uneven tension not only affects production efficiency but can also cause uneven wrinkles or stretching on the webbing's appearance, and in severe cases, even breakage.

[0004] Traditional weft feeding devices control the weft speed using belts. However, over time, these belts wear down due to friction. This wear not only causes material to fall off, creating a source of contamination, but it can also negatively impact the quality of the webbing. Especially during the production of elastic webbing, contaminants from the belt can easily transfer to the webbing surface, causing contamination and affecting its appearance and quality. Belt slack is another common problem with traditional weft feeding devices. Over time, the belt gradually loses tension, weakening the driving force of the weft feeding device and affecting the linear speed of the weft. This slack problem is exacerbated, especially during high-speed loom operation, leading to uneven weft supply and quality issues. Because traditional weft feeding devices rely heavily on belt drives, friction and vibration between the belt and other components during loom operation can cause the belt to loosen, making it difficult to maintain a constant linear speed. Furthermore, belt wear or loosening can cause fluctuations in the linear speed of the weft feeding device, directly affecting the weft tension and consequently the width, appearance, and texture of the webbing, resulting in inconsistent webbing production quality. Summary of the Invention

[0005] The technical problem to be solved by this invention is to address the issue that the linear speed of the weft yarn in belt conveyors is prone to fluctuation, which in turn affects the quality of the webbing products.

[0006] To solve the above-mentioned technical problems, the present invention provides a weft feeding device, comprising: a mounting plate having a limiting groove; a rotating plate having one end rotatably mounted on the mounting plate and the other end having an upper weft feeding wheel; a follower plate having its center rotatably mounted on the mounting plate and both ends having lower weft feeding wheels, the lower weft feeding wheels being located below the upper weft feeding wheel and their surfaces abutting against the surfaces of the upper weft feeding wheel; and a limiting member having one end mounted on the follower plate and the other end located within the limiting groove, the limiting member being movable along the limiting groove.

[0007] Furthermore, the rotating plate includes a rotating part, a mounting part, and a control part. The rotating part and the control part are respectively disposed on both ends of the mounting part. The first end of the rotating part is rotatably disposed on the mounting plate and connected to the mounting part. The width of the rotating part gradually increases from the first end to the second end. The feed weft wheel is disposed on the mounting part.

[0008] Furthermore, the control unit has a first through hole on its side, and the width of the control unit gradually decreases in the direction away from the mounting part.

[0009] Furthermore, it also includes a stepper motor, which is mounted on the mounting part. The mounting part has a second through hole, and the output end of the stepper motor passes through the second through hole and is connected to the upper feed weft wheel. The stepper motor and the upper feed weft wheel are located on opposite sides of the mounting part.

[0010] Furthermore, it also includes a stepper driver, which is disposed at the bottom of the mounting plate and is electrically connected to the stepper motor.

[0011] Furthermore, it also includes a yarn guide limiting member, which is disposed on the mounting plate and has a limiting hole facing the surface of the upper feed weft wheel.

[0012] Furthermore, the yarn guide limiting component includes a base plate and a limiting rod. The base plate is disposed on the mounting plate, one end of the limiting rod is detachably disposed on the base plate, and the limiting hole is disposed on the other end of the limiting rod.

[0013] Furthermore, the distance between the axis of rotation of the follower plate and the axis of rotation of the rotating plate is equal to the distance between the axis of rotation of the feed weft wheel and the axis of rotation of the rotating plate.

[0014] Furthermore, the distance between the rotating shaft of the follower plate and the rotating shafts of the two lower weft rollers is equal, and the height of the rotating shaft of the follower plate is between the heights of the rotating shafts of the two lower weft rollers.

[0015] Furthermore, the follower plate is a triangular plate, and the rotation axis of the follower plate and the rotation axes of the two lower feed weft wheels are respectively located at the three corners of the triangular plate.

[0016] Compared with the prior art, the weft feeding device of this invention has the following advantages: By rotating one end of the rotating plate and setting it on the mounting plate, the upper weft feeding wheel at the other end of the rotating plate naturally presses down to the lower weft feeding wheel by its own weight, ensuring that the upper and lower weft feeding wheels are in close contact, effectively pressing the weft yarn and ensuring the stability of the weft yarn during the feeding process. By rotating the middle part of the follower plate on the mounting plate and using a limiting member to restrict the rotation amplitude of the follower plate, the follower plate can swing freely within a certain range. When there is a gap between the upper and lower weft feeding wheels, the follower plate can automatically adjust its position to eliminate the gap, ensuring complete fit between the weft feeding wheels, ensuring the stability of the weft yarn's linear speed, and improving the consistency and uniformity of the quality of the webbing product.

[0023] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0024] like Figures 1 to 4 As shown, an embodiment of the present invention discloses a weft feeding device, including: a mounting plate 1, a rotating plate 2, a follower plate 3, and a limiting member 4.

[0025] The mounting plate 1 is provided with a limiting groove 101; one end of the rotating plate 2 is rotatably mounted on the mounting plate 1, and the other end of the rotating plate 2 is provided with an upper feeding weft wheel 24; the middle of the follower plate 3 is rotatably mounted on the mounting plate 1, and both ends of the follower plate 3 are provided with lower feeding weft wheels 31, which are located below the upper feeding weft wheel 24, and the wheel surface of the lower feeding weft wheel 31 can abut against the wheel surface of the upper feeding weft wheel 24; one end of the limiting member 4 is provided on the follower plate 3, and the other end of the limiting member 4 is located in the limiting groove 101, and the limiting member 4 can move along the limiting groove 101.

[0026] The weft feeding device of this application rotates one end of the rotating plate 2 onto the mounting plate 1, and the upper weft feeding wheel 24 at the other end of the rotating plate 2 naturally presses down onto the lower weft feeding wheel 31 by its own weight, ensuring that the upper weft feeding wheel 24 and the lower weft feeding wheel 31 are in close contact, effectively pressing the weft yarn and ensuring the stability of the weft yarn during the weft yarn feeding process. By rotating the middle part of the follower plate 3 onto the mounting plate 1 and using the limiting member 4 to limit the rotation amplitude of the follower plate 3, the follower plate 3 can swing freely within a certain range. When there is a gap between the upper weft feeding wheel 24 and the lower weft feeding wheel 31, the follower plate 3 can automatically adjust its position to eliminate the gap, ensuring complete fit between the weft feeding wheels, ensuring the stability of the weft yarn's linear speed, and improving the consistency and uniformity of the quality of the webbing product.

[0027] Weft feeding is achieved by using an upper weft feed roller 24 that naturally presses down onto the lower weft feed roller 31 under its own weight. A follower plate 3 with a rotating shaft structure is also included. When there is a gap between the upper weft feed roller 24 and the lower weft feed roller 31, the follower plate 3 automatically adjusts its position to eliminate these errors, ensuring complete contact between the lower weft feed rollers 31. This allows the weft feeding device to adapt to weft yarns of different thicknesses. This invention eliminates the belt structure, avoiding many problems caused by mechanical adjustments. The adaptive weft feeding method of the upper weft feed roller 24 and the lower weft feed roller 31 has a simple structure, is easy to install, use, and debug, and has high synchronization, effectively ensuring consistency between multiple devices, reducing control differences, and improving product quality.

[0028] Through the coordinated operation of the rotating plate 2 and the follower plate 3, the upper weft feed roller 24 and the lower weft feed roller 31 are always kept in close contact, avoiding the unstable weft delivery caused by poor contact or excessive gaps in the conveyor belt in traditional weft feeding devices, thus ensuring stable weft delivery in the loom. The cooperation between the limiting component 4 and the limiting groove 101 allows the follower plate 3 to automatically adjust its position according to changes in the gap with the upper weft feed roller 24, ensuring optimal contact between the two weft feed rollers and effectively preventing weft feed roller position deviation, thus improving the stability of weft transmission. The free rotation range of the follower plate 3 is limited by the limiting component 4, making the operation of the weft feed rollers smoother, reducing unnecessary friction and fluctuations during weft transmission, thereby improving the product quality of the weft ribbon. Because the stability of the weft feeding device is enhanced, the weft transmission process is more uniform and consistent, the overall quality of the weft ribbon is improved, defects caused by weft feeding problems during production are reduced, and high-quality weft ribbon output is ensured.

[0029] By optimizing the structure of the weft feeding device, excessive wear caused by unstable weft feeding is reduced, thereby extending the device's service life and reducing the frequency of maintenance and repair, further improving production efficiency and reducing production costs. The weft feeding device of this invention effectively solves the shortcomings of traditional weft feeding devices, improves the stability and accuracy of weft feeding during production, thereby increasing weaving production efficiency and making the production process smoother.

[0030] like Figure 1 and Figure 4 As shown, in an optional embodiment of the present invention, the rotating plate 2 includes a rotating part 21, a mounting part 22 and a control part 23. The rotating part 21 and the control part 23 are respectively disposed on both ends of the mounting part 22. The first end of the rotating part 21 is rotatably disposed on the mounting plate 1. The first end of the rotating part 21 is connected to the mounting part 22. The width of the rotating part 21 gradually increases from the first end to the second end. The feed weft wheel 24 is disposed on the mounting part 22.

[0031] By incorporating a control unit 23, operators can better grip the rotating plate 2 to lift the upper weft feed roller 24, facilitating weft yarn replacement or maintenance below the upper weft feed roller 24. The gradually increasing width of the rotating part 21 reduces the rotational contact area of ​​components, minimizing wear and extending the device's lifespan. It also reduces frequent maintenance and repair costs due to excessive wear. The gradually increasing width of the rotating part 21 from the first end to the second end effectively increases the force-bearing area of ​​the mounting part 22 while reducing the rotational contact area of ​​components, enhancing the stability and durability of the rotating part 21. This prevents damage or wear caused by uneven local force distribution, resulting in smoother and more stable operation of the weft feeding device. It effectively reduces potential fluctuations and friction during weft feeding, ensuring uniform weft yarn delivery and thus improving the efficiency and quality of weft production. Specifically, the rotating part 21, mounting part 22, and control unit 23 are integrally formed; the control unit 23 is a triangular plate, and the mounting part 22 is a square plate.

[0032] like Figure 2 and Figure 4 As shown, in an optional embodiment of the present invention, the control part 23 has a first through hole 201 on its side, and the width of the control part 23 gradually decreases in the direction away from the mounting part 22. By making the width of the control part 23 gradually decrease in the direction away from the mounting part 22, the structure of the control part 23 is made more compact, thereby effectively saving space, optimizing the overall structure of the weft feeding device, and making the weft feeding device more flexible in installation and adaptable to different spatial environments. By providing the first through hole 201 on the side of the control part 23, the weight of the control part 23 can be effectively reduced, unnecessary material accumulation can be reduced, and while maintaining its structural strength, the stability of the control part 23 can be enhanced. This helps the operator to hold the control part 23 through the first through hole 201 to control the height of the upper weft feeding roller 24.

[0033] like Figure 3 and Figure 4 As shown, in an optional embodiment of the present invention, a stepper motor 5 is also included. The stepper motor 5 is disposed on the mounting part 22. The mounting part 22 is provided with a second through hole 202. The output end of the stepper motor 5 passes through the second through hole 202 and is connected to the upper feed weft wheel 24. The stepper motor 5 and the upper feed weft wheel 24 are respectively located on both sides of the mounting part 22.

[0034] By installing a stepper motor 5 on the mounting section 22, high-precision control is provided, ensuring that the upper weft feed roller 24 of the weft feeding device can accurately execute each action during operation, thus improving the operational accuracy and stability of the weft feeding device. The stepper motor 5 connects to the upper weft feed roller 24 through the second through-hole 202 via its output end, ensuring the compactness and efficiency of the transmission structure. This allows the stepper motor 5 to stably drive the upper weft feed roller 24, enhancing the device's working efficiency. By placing the stepper motor 5 and the upper weft feed roller 24 on opposite sides of the mounting section 22, space is fully utilized, and internal structural congestion is avoided, contributing to the overall compactness and rationality of the device and enhancing its structural stability. Directly mounting the stepper motor 5 on the mounting section 22 and connecting it to the upper weft feed roller 24 reduces unnecessary parts, lowers the risk of mechanical wear, and helps improve the device's service life and reliability. The simple connection structure between the stepper motor 5 and the upper weft feed roller 24 reduces complex mechanical components, simplifies installation and subsequent maintenance, and improves the overall operability of the device.

[0035] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, a stepper driver 6 is also included. The stepper driver 6 is disposed at the bottom of the mounting plate 1 and is electrically connected to the stepper motor 5.

[0036] By electrically connecting the stepper driver 6 to the stepper motor 5, the drive system can more precisely control the movement of the stepper motor 5, improving the overall performance of the weft feeding device. The stepper driver 6 can provide more precise current signals as needed, thereby improving the accuracy and response speed of motor control. The stepper driver 6, located at the bottom of the mounting plate 1, effectively isolates the operating vibrations of the motor and driver, reducing the impact on other mechanical components, thus making the entire weft feeding device operate more smoothly and stably, reducing potential malfunctions or anomalies. The stepper driver 6's location at the bottom of the mounting plate 1 makes efficient use of space and effectively simplifies the overall layout of the weft feeding device. This structure not only makes the device more compact but also improves the convenience of installation and debugging. The electrical connection between the stepper driver 6 and the stepper motor 5 simplifies the wiring of the electrical system, helping to improve the maintenance efficiency and reliability of the electrical components. Operators can more easily perform daily maintenance and troubleshooting, reducing downtime and maintenance costs.

[0037] By setting the stepper driver 6, more precise current regulation can be achieved, improving the response speed of the stepper motor 5 under different operating conditions, ensuring the working efficiency and accuracy of the weft feeding device, and helping to improve product quality and the overall operating efficiency of the production line. The electrical connection scheme between the stepper driver 6 and the stepper motor 5 facilitates integration with other control systems or devices, offering better compatibility and expandability, meeting the needs of different production environments, and improving the adaptability of the device. Setting the stepper driver 6 enables the motor to respond quickly and adapt well to speed changes, ensuring smooth production. The automatic speed change function can be flexibly adjusted according to the actual operating speed of the loom, helping to expand product variety and meet more production process requirements.

[0038] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, a yarn guide limiting member 7 is also included. The yarn guide limiting member 7 is disposed on the mounting plate 1 and has a limiting hole 701 facing the surface of the upper feed weft wheel 24.

[0039] By providing a limiting hole 701 facing the surface of the upper weft feed roller 24, the yarn guide limiting component 7 facilitates the adjustment of the transport direction of the weft yarn passing through the limiting hole 701, and facilitates the clamping of the weft yarn by the upper weft feed roller 24 and the lower weft feed roller 31. The limiting hole 701 on the yarn guide limiting component 7 can effectively adjust the transport direction of the weft yarn, ensuring that the yarn passes stably through the weft feeding device without deviation or interference, guaranteeing smooth yarn delivery, and improving the accuracy in the weaving process. The limiting hole 701 makes the cooperation between the upper weft feed roller 24 and the lower weft feed roller 31 closer, ensuring that the weft yarn is precisely held during the weft feeding process, thereby avoiding yarn slack or slippage, and improving the uniformity and quality of the fabric. Through the setting of the yarn guide limiting component 7, the transport direction of the weft yarn is effectively controlled, reducing the need for frequent adjustments to the weft feeding device, reducing operational complexity, and improving production efficiency. The yarn guide limiting component 7 helps stabilize the working state of the weft feeding device, preventing yarn swaying or irregular operation, enhancing the stability and reliability of the device during high-speed operation, and ensuring the continuity of the production process. Specifically, the height of the limiting hole 701 is located between the shaft height of the lower weft feeding wheel 31 and the shaft height of the upper weft feeding wheel 24.

[0040] In an optional embodiment of the present invention, the yarn guide limiting member 7 consists of two pressing wheels, which are mounted on the mounting plate 1 and the wheel surfaces of the two pressing wheels abut against each other.

[0041] like Figure 1 and Figure 3 As shown, in an optional embodiment of the present invention, the yarn guide limiting member 7 includes a base plate 71 and a limiting rod 72. The base plate 71 is disposed on the mounting plate 1, one end of the limiting rod 72 is detachably disposed on the base plate 71, and the limiting hole 701 is disposed on the other end of the limiting rod 72.

[0042] By employing a base plate 71 and a limiting bar 72, the entire weft feeding device is simplified and compacted, effectively reducing mechanical complexity, improving stability, and facilitating large-scale production and assembly. One end of the limiting bar 72 is detachably mounted on the base plate 71, making its replacement and maintenance more convenient. Operators can perform maintenance or replacement simply by disassembling the limiting bar 72, reducing maintenance difficulty, improving work efficiency, and minimizing downtime, thus ensuring continuous production. The detachable limiting bar 72 allows operators to flexibly adjust its position or replace it with different specifications to meet various weaving process requirements, improving the device's adaptability and meeting diverse production needs. The disassembly structure between the limiting bar 72 and the base plate 71 ensures the stability of the limiting hole 701 during operation. The installation method of the limiting bar 72 prevents loosening or detachment during operation, enhancing the reliability of the yarn guide limiting component 7 and ensuring the weft feeding device maintains good performance even during long-term operation. The limiting hole 701 is located at the other end of the limiting bar 72, which helps to adjust and fix the running direction of the weft yarn. The operator can easily adjust the position of the limiting bar 72 according to actual needs, thereby precisely controlling the feed path of the weft yarn, ensuring smooth yarn transmission and processing effect, and improving weaving quality.

[0043] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the distance between the rotating shaft of the follower plate 3 and the rotating shaft of the rotating plate 2 is equal to the distance between the rotating shaft of the feed weft wheel 24 and the rotating shaft of the rotating plate 2.

[0044] By setting the distance between the rotating shaft of the follower plate 3 and the rotating shaft of the rotating plate 2 to be equal to the distance between the rotating shaft of the upper weft feed wheel 24 and the rotating shaft of the rotating plate 2, the movement of the follower plate 3 and the rotating plate 2 can be synchronized. This ensures that the upper weft feed wheel 24 and the lower weft feed wheel 31 abut against each other, enabling precise coordination between weft yarn delivery and weft wheel control during operation, thereby improving the stability and precision of the weaving process. This distance matching allows the various components of the weft feed device to work more precisely, reducing potential errors during operation. Precise distance matching helps maintain stable weft yarn delivery, avoiding uneven weft yarn or yarn slippage caused by asynchronous component operation, thus improving the quality of woven products. Since the rotating shaft distances between the follower plate 3 and the rotating plate 2 are equal, the balance of each component during movement is ensured, avoiding excessive wear caused by imbalance or uneven friction between components. This helps extend the service life of the weft feed device and reduces maintenance costs due to repair or replacement of parts. Ensuring that the rotational distances of the follower plate 3 and the rotating plate 2 are consistent with other relevant rotational distances makes the adjustment process of the weft wheel more intuitive and convenient. Operators no longer need complex adjustments and can quickly calibrate as needed, improving operational efficiency and reducing downtime during production. Simultaneously, it maintains the overall stability of the weft feeding device, reducing potential weft wheel instability caused by relative displacement between different components. Synchronized rotational shaft coordination makes the interaction between various transmission components smoother, contributing to improved reliability of the entire weaving device and reducing the probability of malfunctions.

[0045] By employing a well-designed shaft distance, the weft feeding device maintains high power transmission efficiency during operation, reducing energy waste caused by uncoordinated component movements. Synchronized movement and precise structure not only improve work efficiency but also help reduce energy consumption during device operation, optimizing energy utilization in the production process and enhancing the overall performance of the weft feeding device. Precise distance matching reduces problems caused by mechanical errors or instability, thereby improving the device's ability to precisely control the weft yarn during high-speed weaving. A more stable weft feeding process contributes to fabric consistency and uniformity, meeting the production requirements of high-quality fabrics.

[0046] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the distance between the rotating shaft of the follower plate 3 and the rotating shaft of the two lower weft rollers 31 is equal, and the height of the rotating shaft of the follower plate 3 is between the heights of the rotating shafts of the two lower weft rollers 31.

[0047] By setting the distance between the rotating shaft of the follower plate 3 and the rotating shaft of the lower weft roller 31 to be equal, and ensuring that the height of the rotating shaft of the follower plate 3 is between the heights of the rotating shafts of the two lower weft rollers 31, more precise weft feeding control can be achieved. This ensures the coordination between the follower plate 3 and the lower weft roller 31, effectively avoiding weft imbalance or uneven feeding caused by inconsistent rotating shaft positions, thereby improving the stability and precision of weaving. The distance and height configuration between the follower plate 3 and the lower weft roller 31 enables more efficient synchronous movement. The close relative position of the follower plate 3 and the lower weft roller 31 reduces mechanical interference between components, ensuring smooth weft feeding and reducing the possibility of mechanical jamming. Optimizing the rotating shaft positions of the follower plate 3 and the lower weft roller 31 helps ensure the smooth feeding of weft into the loom, and the fed weft maintains stable and uniform tension, thereby improving the overall quality of the fabric. Especially in high-speed weaving, it ensures that the fabric surface is free of undulations or uneven weave patterns, guaranteeing the production of high-quality fabrics. The consistent distance between the shafts of the follower plate 3 and the lower weft feed roller 31 further enhances the stability of the weft feeding device. During weaving, all components maintain relative balance and synchronization, enabling the entire weft feeding device to operate stably under different working conditions and reducing operational instability caused by component asymmetry or asynchrony. The matching shaft distance and height between the follower plate 3 and the lower weft feed roller 31 avoids unnecessary energy waste. Because the movements of each component are more coordinated, potential energy losses during mechanical movement are reduced, achieving higher transmission efficiency and effectively lowering the device's energy consumption.

[0048] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the follower plate 3 is a triangular plate, and the rotation axis of the follower plate 3 and the rotation axis of the two lower feed weft wheels 31 are respectively located at the three corners of the triangular plate.

[0049] By employing a triangular plate as the follower plate 3, the triangular shape of the follower plate 3 makes the relative positions between the various rotating shafts more stable, effectively dispersing the force and enhancing the overall structural stability of the weft feeding device. Positioning the rotating shafts of the follower plate 3 and the lower weft feeding wheel 31 at the three corners of the triangular plate ensures coordinated movement of all components of the weft feeding device, improving the smoothness and uniformity of weft feeding. This facilitates more precise control of the weft feeding process, avoiding uneven weft feeding caused by asymmetry or instability between components, thereby improving fabric quality. The triangular plate structure helps to rationally distribute mechanical load, reduce pressure on individual components, decrease wear, extend the device's service life, and adapt to the production needs of different types of fabrics, enhancing the adaptability and flexibility of the weft feeding device in diverse production environments.
