Description

Technical Field

[0001] The invention relates to the technical field of special devices for textile and light industry, in particular to a weft feeding device. Background Art

[0002] Elastic webbing is widely used in clothing, medical, sporting goods and other industries. Its production quality directly affects the comfort, durability and aesthetics of the product. In the production process of elastic webbing, the linear speed of the weft is a crucial parameter, which directly determines the width, appearance and texture of the webbing. In order to ensure the stability and high quality of webbing production, ensuring the uniform linear speed of the weft is a key task in the production process.

[0003] In the production process of elastic webbing, the loom manufactures the webbing by interweaving the warp and weft yarns. The uneven linear speed of the weft will directly affect the width and appearance of the webbing. Specifically, when the linear speed of the weft fluctuates, the width of the webbing will become unstable, which may cause the webbing to have irregular shapes or dimensional deviations in the finished product. In addition, the linear speed fluctuation of the weft may also cause changes in the width, appearance and texture of the webbing, affect the softness and flatness of the webbing, and even reduce the strength of the webbing. The change of the tension of the weft is also an important factor affecting the quality of the webbing. When the speed of the weft is unstable, the tension of the webbing will also fluctuate, which will in turn affect the tightness and elasticity of the webbing, making the overall performance of the webbing not as expected. Uneven tension not only affects the production efficiency of the webbing, but may also cause uneven wrinkles or stretching in the appearance of the webbing, and even cause the webbing to break in severe cases.

[0004] The traditional weft delivery device uses a belt to control the conveying speed of the weft. However, over time, the belt will wear due to friction. Belt wear not only causes material to fall off and forms a pollution source, but also such wear may have a negative impact on the quality of the webbing. Especially in the process of producing elastic webbing, the pollutants generated by the belt are easily transferred to the surface of the webbing, causing contamination of the webbing, thus affecting the appearance and quality of the webbing. Belt loosening is another common problem of the traditional weft delivery device. The belt will gradually lose tension during long-term use, resulting in a weakening of the driving ability of the weft delivery device, which in turn affects the linear speed of the weft. Especially when the loom is running at high speed, the belt loosening problem will be more serious, resulting in uneven weft supply, which will cause quality problems of the webbing. Since the traditional weft delivery device relies more on belt transmission, during the operation of the loom, factors such as friction and vibration between the belt and other components may cause the belt to loosen, making it impossible for the belt to maintain a constant linear speed. Moreover, the wear or looseness of the belt will also cause the linear speed of the weft delivery device to fluctuate, directly affecting the tension of the weft, and then affecting the width, appearance and texture of the webbing, making the production quality of the weft unstable. Summary of the invention

[0023] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be appreciated by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present invention. Similarly, for clarity and conciseness, 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, comprising: a mounting plate 1, a rotating plate 2, a follower plate 3 and a limiting member 4.

[0025] Among them, the mounting plate 1 is provided with a limiting groove 101; one end of the rotating plate 2 is rotatably set on the mounting plate 1, and the other end of the rotating plate 2 is provided with an upper weft sending wheel 24; the middle part of the following plate 3 is rotatably set on the mounting plate 1, and both ends of the following plate 3 are provided with lower weft sending wheels 31, which are located below the upper weft sending wheel 24, and the wheel surface of the lower weft sending wheel 31 can be against the wheel surface of the upper weft sending wheel 24; one end of the limiting member 4 is set on the following 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 sending device of the present application is configured such that one end of a rotating plate 2 is rotatably set on a mounting plate 1, and an upper weft sending wheel 24 at the other end of the rotating plate 2 is naturally pressed down to a lower weft sending wheel 31 by its own weight, so as to ensure that the upper weft sending wheel 24 is in close contact with the lower weft sending wheel 31, and the weft yarn can be effectively compressed, thereby ensuring the stability of the weft yarn during transportation; the middle part of a follower plate 3 is rotatably set on the mounting plate 1, and a limiter 4 is used to limit the rotation range of the follower plate 3, so that the follower plate 3 can swing freely within a certain range; when there is a gap between the upper weft sending wheel 24 and the lower weft sending wheel 31, the follower plate 3 can automatically adjust its position to eliminate the gap, thereby ensuring that the weft sending wheels are fully fitted together, ensuring the linear speed stability of the weft yarn, and improving the consistency and uniformity of the quality of the weft products.

[0027] The weft is sent by setting an upper weft sending wheel 24 that naturally presses down to the lower weft sending wheel 31 by its own weight, and a follower plate 3 with a rotating shaft structure is also set. When there is a gap between the upper weft sending wheel 24 and the lower weft sending wheel 31, the follower plate 3 can automatically adjust the position to eliminate these errors, ensure the complete fit between the lower weft sending wheels 31, and enable the weft sending device to adapt to wefts of different thicknesses. The present invention removes the belt structure and avoids many problems caused by mechanical adjustment. The adaptive weft sending method of the upper weft sending wheel 24 and the lower weft sending wheel 31 has a simple structure, is easy to install, use and debug, and has high synchronization, which can effectively ensure the consistency between multiple devices, reduce control differences, and improve product quality.

[0028] Through the coordination of the rotating plate 2 and the follower plate 3, it is ensured that the upper weft delivery wheel 24 and the lower weft delivery wheel 31 always maintain close contact, avoiding the unstable weft delivery caused by poor contact of the conveyor belt or excessive gap in the traditional weft delivery device, thereby ensuring the stable delivery of the weft in the loom. Through the coordination of the limiter 4 and the limiter groove 101, the follower plate 3 can automatically adjust its position according to the change of the gap between it and the upper weft delivery wheel 24, ensuring that the two weft delivery wheels always maintain the best contact state, effectively avoiding the problem of position deviation of the weft delivery wheel, and improving the transmission stability of the weft. The free rotation range of the follower plate 3 is limited by the limiter 4, which makes the weft delivery wheel work more smoothly, reduces unnecessary friction and fluctuations in the weft delivery process, and thus improves the product quality of the weft. Since the stability of the weft delivery device is enhanced, the weft delivery process is more uniform and consistent, the overall quality of the weft is improved, the defects caused by weft delivery problems in the production process are reduced, and the high-quality output of the weft is ensured.

[0029] By optimizing the structure of the weft delivery device, excessive wear of the device caused by unstable weft delivery is reduced, thereby extending the service life of the device, reducing the frequency of maintenance and repair, further improving production efficiency and reducing production costs. The weft delivery device of the present invention effectively solves the shortcomings of traditional weft delivery devices, improves the stability and accuracy of weft delivery during the production process, thereby improving the efficiency of weaving production 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 arranged on both ends of the mounting part 22, the first end of the rotating part 21 is rotatably arranged 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, and the upper weft feeding wheel 24 is arranged on the mounting part 22.

[0031] By setting the control part 23, the operator can better hold the rotating plate 2 to lift the upper weft delivery wheel 24, so as to facilitate the replacement or maintenance of the weft under the upper weft delivery wheel 24. By gradually increasing the width of the rotating part 21, the rotation contact area of ​​the components is reduced, the wear is reduced, the service life of the device is extended, and the frequent maintenance and repair costs caused by excessive wear are reduced. The width of the rotating part 21 gradually increases from the first end to the second end, which effectively increases the force area of ​​the mounting part 22, while reducing the rotation contact area of ​​the components, enhancing the stability and durability of the rotating part 21, avoiding damage or wear caused by uneven local force, making the operation of the weft delivery device more stable and stable, effectively reducing the fluctuations and friction that may occur during the weft delivery process, ensuring the uniform delivery of the weft, thereby improving the efficiency and product quality of the ribbon production. Specifically, the rotating part 21, the mounting part 22 and the control part 23 are integrally formed, the control part 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, a first through hole 201 is provided on the side of the control part 23, and the width of the control part 23 gradually decreases in the direction away from the mounting part 22. By gradually reducing the width of the control part 23 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 sending device, and making the weft sending device more flexible during 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 is enhanced, which helps the operator to hold the control part 23 through the first through hole 201 to control the height of the upper weft sending wheel 24.

[0033] like Figure 3 and Figure 4 As shown, in an optional embodiment of the present invention, it also includes a stepper motor 5, which is arranged on the mounting portion 22. The mounting portion 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 weft sending wheel 24. The stepper motor 5 and the upper weft sending wheel 24 are respectively located on both sides of the mounting portion 22.

[0034] By arranging the stepper motor 5 on the mounting portion 22, high-precision control is provided to ensure that the upper weft sending wheel 24 of the weft sending device can accurately perform each action during the working process, thereby improving the operating accuracy and stability of the weft sending device. The stepper motor 5 is connected to the upper weft sending wheel 24 through the second through hole 202 through the output end, which ensures the compactness and efficiency of the transmission structure, so that the stepper motor 5 can stably drive the upper weft sending wheel 24, thereby enhancing the working efficiency of the device. By arranging the stepper motor 5 and the upper weft sending wheel 24 on both sides of the mounting portion 22 respectively, the space is fully utilized, and the crowding of the internal structure of the device is avoided, which helps to improve the compactness and rationality of the overall device and enhance the structural stability of the weft sending device. By directly mounting the stepper motor 5 on the mounting portion 22 and connecting it to the upper weft sending wheel 24, unnecessary parts are reduced, the risk of mechanical wear is reduced, and the service life and reliability of the device are improved. The stepper motor 5 and the upper weft sending wheel 24 are transmitted through a simple connection structure, which not only reduces complex mechanical components, but also simplifies the installation and later maintenance process, and improves the operability of the overall device.

[0035] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, a stepper driver 6 is further included. The stepper driver 6 is arranged at the bottom of the mounting plate 1 , and the stepper driver 6 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 accurately control the action of the stepper motor 5 and improve the overall performance of the weft delivery device. The stepper driver 6 can provide a more accurate current signal as required, thereby improving the accuracy and response speed of the motor control. The stepper driver 6 is arranged at the bottom of the mounting plate 1, which can effectively isolate the working vibration of the motor and the driver and reduce the impact on other mechanical components, so that the entire weft delivery device can run more smoothly and stably, reducing possible failures or abnormalities. The stepper driver 6 is located at the bottom of the mounting plate 1, which makes rational use of space and effectively simplifies the overall layout of the weft delivery device. Such a 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 makes the wiring of the electrical system more concise, which helps to improve the maintenance efficiency and reliability of the electrical part. Operators can more conveniently perform daily maintenance and troubleshooting, reducing downtime and maintenance costs.

[0037] By setting the stepper driver 6, more accurate current regulation can be achieved, the response speed of the stepper motor 5 under different working conditions can be improved, the working efficiency and accuracy of the weft feeding device can be ensured, and the production quality of the product and the overall operating efficiency of the production line can be improved. The electrical connection scheme between the stepper driver 6 and the stepper motor 5 is convenient for integration with other control systems or devices, has better compatibility and scalability, can meet the needs of different production environments, and improve the adaptability of the device. By setting the stepper driver 6, the motor responds quickly and can adapt well to changes in speed, ensuring the smooth progress of the production process. The automatic speed change function can be flexibly adjusted according to the actual operating speed of the loom, which helps to expand the 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, it further includes a yarn guide limiter 7, which is arranged on the mounting plate 1 and has a limit hole 701 facing the wheel surface of the upper weft feeding wheel 24.

[0039] By providing a limiting hole 701 facing the wheel surface of the upper weft delivery wheel 24 on the yarn guide limiting member 7, it is convenient to adjust the transport direction of the weft thread passing through the limiting hole 701, and it is convenient for the upper weft delivery wheel 24 and the lower weft delivery wheel 31 to clamp the weft thread. The limiting hole 701 on the yarn guide limiting member 7 can effectively adjust the transport direction of the weft thread, ensure that the yarn passes through the weft delivery device stably without deviation or interference, ensure the smooth transportation of the yarn, and improve the accuracy during the weaving process. The limiting hole 701 makes the cooperation between the upper weft delivery wheel 24 and the lower weft delivery wheel 31 closer, ensure that the weft thread is accurately supported during the weft delivery process, thereby avoiding the phenomenon of yarn relaxation or slippage, and improving the uniformity and quality of the fabric. Through the setting of the yarn guide limiting member 7, the transport direction of the weft thread is effectively controlled, the need for frequent adjustment of the weft delivery device is reduced, the complexity of operation is reduced, and the production efficiency is improved. The yarn guide limiter 7 helps stabilize the working state of the weft delivery device, prevents the yarn from swinging or running irregularly, enhances the stability and reliability of the device during high-speed operation, and ensures the continuity of the production process. Specifically, the height of the limit hole 701 is between the height of the rotating shaft of the lower weft delivery wheel 31 and the height of the rotating shaft of the upper weft delivery wheel 24.

[0040] In an optional embodiment of the present invention, the yarn guide limiting member 7 is two crimping wheels, and the two crimping wheels are arranged on the mounting plate 1, and the wheel surfaces of the two crimping 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 limiter 7 includes a base plate 71 and a limit rod 72, the base plate 71 is arranged on the mounting plate 1, one end of the limit rod 72 is detachably arranged on the base plate 71, and the limit hole 701 is arranged on the other end of the limit rod 72.

[0042] By adopting the bottom plate 71 and the limiting rod 72, the structure of the entire weft delivery device is simpler and more compact, which can effectively reduce the mechanical complexity, improve the stability of the device, and facilitate large-scale production and assembly. One end of the limiting rod 72 is detachably arranged on the bottom plate 71, making the replacement and maintenance of the limiting rod 72 more convenient. The operator only needs to disassemble the limiting rod 72 for maintenance or replacement, which reduces the difficulty of maintenance, improves work efficiency, and also reduces the downtime of the device, ensuring the continuity of production. Through the detachable limiting rod 72, the operator can flexibly adjust the position of the limiting rod 72 or replace the limiting rod 72 of different specifications according to different production needs, so as to adapt to various different weaving process requirements, improve the adaptability of the device, and meet diversified production needs. The disassembly structure between the limiting rod 72 and the bottom plate 71 ensures the stability of the limiting hole 701 during the working process. The installation method of the limiting rod 72 makes it difficult to loosen or fall off during operation, enhances the reliability of the yarn guide limiting member 7, and ensures that the weft delivery device can still maintain good performance under long-term operation. The limiting hole 701 is arranged at the other end of the limiting rod 72, which helps to adjust and fix the running direction of the weft. The operator can conveniently adjust the position of the limiting rod 72 according to actual needs, thereby accurately controlling the feeding path of the weft, ensuring the smooth transmission and processing effect of the yarn, and improving the weaving quality.

[0043] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the distance between the rotating axis of the follower plate 3 and the rotating axis of the rotating plate 2 is equal to the distance between the rotating axis of the upper weft feeding wheel 24 and the rotating axis 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 delivery wheel 24 and the rotating shaft of the rotating plate 2, the movement synchronization between the follower plate 3 and the rotating plate 2 can be ensured, and the upper weft delivery wheel 24 and the lower weft delivery wheel 31 can be ensured to abut against each other, so that the weft delivery device can accurately match the weft delivery and the weft wheel control during operation, thereby improving the stability and accuracy of the weaving process. This distance matching enables the various components of the weft delivery device to work more accurately and reduces the errors that may occur during operation. Accurate distance matching helps to maintain the stable feeding of the weft, avoid uneven weft or falling off due to asynchronous components, and improve 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 in motion is ensured, and excessive wear caused by imbalance or uneven friction between components is avoided, which helps to extend the service life of the weft delivery device and reduce the maintenance cost increased by repairing or replacing parts. Ensure that the shaft distance between the follower plate 3 and the rotating plate 2 is consistent with the other related shaft distances, making the adjustment process of the entire weft wheel more intuitive and convenient. Operators do not need to make complex adjustments and can calibrate more quickly as needed, which improves operating efficiency and reduces downtime in the production process. At the same time, it can also maintain the stability of the overall structure of the weft delivery device and reduce the instability of the weft wheel that may be caused by the relative displacement between different components. The synchronous shaft coordination makes the interaction between the various transmission components more stable, which helps to improve the working reliability of the entire weaving device and reduce the probability of failure.

[0045] Through reasonable shaft distance, the weft delivery device can maintain good power transmission efficiency during operation, reducing energy waste caused by uncoordinated component movement. Synchronous movement and precise structure not only improve work efficiency, but also help reduce energy consumption during device operation, optimize energy utilization in the production process, and help improve the overall performance of the weft delivery device. Through precise distance matching, problems caused by mechanical errors or instability are reduced, thereby improving the weft delivery device's ability to accurately control the weft during high-speed weaving. A more stable weft delivery process helps the consistency and uniformity of the fabric, meeting the production needs 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 shafts of the two lower weft sending wheels 31 is equal, and the rotating shaft height of the follower plate 3 is located between the rotating shaft heights of the two lower weft sending wheels 31.

[0047] By setting the distance between the rotating shaft of the follower plate 3 and the rotating shaft of the lower weft delivery wheel 31 to be equal, and ensuring that the rotating shaft height of the follower plate 3 is located between the rotating shaft heights of the two lower weft delivery wheels 31, more accurate weft feeding control can be achieved, the coordination between the follower plate 3 and the lower weft delivery wheel 31 is ensured, and the imbalance or uneven feeding of the weft caused by inconsistent rotating shaft positions is effectively avoided, thereby improving the stability and accuracy of weaving, so that the distance and height configuration between the follower plate 3 and the lower weft delivery wheel 31 can achieve more efficient synchronous movement. The relative position relationship between the follower plate 3 and the lower weft delivery wheel 31 is close, which reduces the mechanical interference between the various components, ensures the smooth weft delivery process, and reduces the possibility of mechanical jamming. The optimization of the rotating shaft position of the follower plate 3 and the lower weft delivery wheel 31 helps to ensure the smooth feeding of the weft into the loom, and the fed weft can maintain a stable and uniform tension, thereby improving the overall quality of the fabric. In particular, during high-speed weaving, it is ensured that there is no undulation or uneven weaving pattern on the surface of the fabric, ensuring the production of high-quality fabrics. The consistent distance between the rotating shaft of the follower plate 3 and the rotating shaft of the lower weft delivery wheel 31 further improves the stability of the weft delivery device. During the weaving process, all components maintain relative balance and synchronization, so that the entire weft delivery device can operate stably under different working conditions, reducing the unstable operation caused by asymmetric or asynchronous components. The rotating shaft distance and height matching between the follower plate 3 and the lower weft delivery wheel 31 avoid unnecessary energy waste. Since the movement of each component is more coordinated, the possible energy loss in the mechanical movement can be reduced, and a higher transmission efficiency can be achieved, thereby effectively reducing the energy consumption of the device.

[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 rotating shaft of the follower plate 3 and the rotating shafts of the two lower weft feeding wheels 31 are respectively located at the three corners of the triangular plate.

[0049] By using a triangular plate as the follower plate 3, the triangular plate-shaped follower plate 3 makes the relative position between the various rotating shafts more stable, effectively disperses the force, and enhances the overall structural stability of the weft delivery device. The rotating shaft of the follower plate 3 and the rotating shaft of the lower weft delivery wheel 31 are respectively arranged at the three corners of the triangular plate, which can ensure the coordinated movement of the various components of the weft delivery device, improve the stability and uniformity of the weft delivery, and help to more accurately control the weft delivery process, avoid uneven weft delivery caused by asymmetry or instability between components, and thus improve the quality of the fabric. The triangular plate structure helps to reasonably distribute the mechanical load, reduce the pressure of a single component, reduce wear, and extend the service life of the device. It can adapt to the production needs of different types of fabrics and enhance the adaptability and flexibility of the weft delivery device in a diversified production environment.

[0050] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution disclosed in the present invention can be achieved, and this document does not limit this.

[0051] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the principles of the present invention should be included in the protection scope of the present invention.
