Description

Technical Field

[0001] This application relates to the technical field of shuttles, and more particularly to a shuttle for a circular loom. Background Technology

[0002] Currently, most circular loom shuttles use a rigid shaft positioning structure to achieve axial limiting. This structure has a rigid metal shaft fixed to the end of the shuttle, with a wear-resistant alloy slider mounted on the shaft end. The slider directly contacts the inner wall of the annular track. Precision machining ensures the perpendicularity of the rigid shaft to the shuttle body, and the axial displacement of the shuttle is controlled by the clearance between the slider and the track, thereby maintaining axial stability during high-speed shuttle movement.

[0003] However, this rigid positioning structure has obvious limitations. Because it relies entirely on mechanical clearance, the clearance increases rapidly when the slider wears due to long-term friction, leading to increased axial movement of the shuttle. Furthermore, rigid contact cannot buffer the impact loads generated by high-speed motion, easily causing shuttle vibration. This not only affects the flatness of the fabric but also increases yarn tension fluctuations, especially when weaving fine denier yarns, which can easily cause yarn breakage, requiring frequent machine stops to replace the slider to ensure production quality. Summary of the Invention

[0004] This application addresses the shortcomings of existing technologies by providing a circular loom shuttle.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows:

[0006] A circular loom shuttle includes a shuttle body, a mounting seat is provided on the inner side of the shuttle body near its direction of movement, and a spring shaft assembly is provided on the mounting seat for changing the distance between the two ends of the inner side of the shuttle body.

[0007] Furthermore, a weft yarn tube is provided between the two ends of the inner side of the shuttle body. The weft yarn tube is connected to the shuttle body through a spring shaft assembly, which can press the weft yarn tube tightly.

[0008] Furthermore, the spring shaft assembly includes a spring, an adjusting block, and a clamping seat. The adjusting block and the clamping seat are connected by a spring, which is arranged along the length of the shuttle body. The adjusting block is connected to a mounting base, and the clamping seat is used to connect to the weft yarn tube.

[0009] Furthermore, a limiting block is fixed to the outer wall of the adjusting block, and the spring is sleeved on the outer wall of the adjusting block and connected to the limiting block.

[0010] Furthermore, the outer wall of the adjusting block is threadedly connected to the mounting base, and a hexagonal adjusting groove is provided at the end of the adjusting block away from the clamping seat, through which the adjusting block and the mounting base can rotate relative to each other.

[0011] Furthermore, the clamping seat includes a bearing and a clamping block, the bearing and the clamping block are coaxially rotatably connected, the clamping block is connected to the weft yarn tube, and the bearing is fixedly connected to the spring.

[0012] Furthermore, a connecting groove is coaxially provided on the clamping block, and an annular block is fixed at the end of the clamping block away from the spring. The weft yarn tube is connected to the clamping block in a position and shape that are compatible.

[0013] Furthermore, the clamping seat is equipped with a displacement sensor. When the displacement sensor detects axial vibration of the clamping seat, it generates a monitoring signal and sends it.

[0014] Furthermore, the clamping seat is made of silicon carbide ceramic composite material.

[0015] Furthermore, the shuttle body is provided with an elastic baffle, which abuts against the outer wall of the weft yarn tube.

[0016] In summary, compared with the prior art, the beneficial effects of the above technical solution are:

[0017] The circular loom shuttle described in this application, by providing a mounting base with a spring shaft assembly on the inside of the shuttle body, allows for flexible adjustment of the distance between the two ends of the shuttle body, achieving stable clamping of the weft yarn tube. This structure can adapt to yarn tubes of different specifications, reducing yarn loosening or misalignment, improving the stability of weft yarn transport, and reducing problems such as yarn breakage and uneven weave caused by yarn misalignment during the weaving process. Simultaneously, the elastic pressure of the spring shaft assembly can buffer the vibration during high-speed shuttle movement, reducing yarn tube wear, extending component life, and ultimately improving the weaving efficiency and product quality of the circular loom, while enhancing the equipment's operational adaptability.

[0022] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0023] This application discloses a shuttle for a circular loom.

[0024] Reference Figures 1-3 A circular loom shuttle includes a shuttle body 1. A mounting base 2 is located on the inner side of the shuttle body 1 near its direction of movement. A spring shaft assembly is mounted on the mounting base 2, and the spring shaft assembly is used to change the distance between the two ends of the inner side of the shuttle body 1. A weft yarn tube 3 is located between the two ends of the inner side of the shuttle body 1. The weft yarn tube 3 is connected to the shuttle body 1 via the spring shaft assembly, and the spring shaft assembly can press the weft yarn tube 3 tightly.

[0025] A mounting base 2 and a spring shaft assembly are located on the inner side of the shuttle body 1 near the direction of movement. The distance between the two ends of the shuttle body 1 can be adjusted via the spring shaft assembly, providing basic adjustment capability for the installation of the weft yarn tube 3 in different scenarios. This enhances the flexibility and adaptability of the shuttle structure and lays the structural foundation for the subsequent stable fixing of the yarn tube. The weft yarn tube 3 is connected to and pressed against the shuttle body 1 via the spring shaft assembly, which uses the pressure of the spring shaft assembly to stably restrict the yarn tube between the two ends of the shuttle body 1. During movement, the end of the shuttle body 1 furthest from the mounting base 2 can stably hold the weft yarn tube 3 in the desired position, preventing axial movement or loosening of the yarn tube during shuttle movement. This ensures the continuity and stability of weft delivery and reduces weaving defects caused by yarn tube displacement.

[0026] The spring shaft assembly includes a spring 4, an adjusting block 5, and a clamping seat 6. The adjusting block 5 and the clamping seat 6 are coaxially connected via the spring 4, which is positioned along the length of the shuttle body 1. The adjusting block 5 is connected to the mounting base 2, and the clamping seat 6 is coaxially connected to the weft yarn tube 3. The spring 4's position along the length of the shuttle body 1 allows its elastic force to act directly on the axial direction of the yarn tube. The precise transmission of elastic force is achieved through the cooperation of the adjusting block 5 and the clamping seat 6. Furthermore, the division of labor among the three components facilitates individual maintenance or replacement, reducing the overall maintenance cost of the assembly.

[0027] A limiting block 7 is fixedly provided on the outer wall of the adjusting block 5. The limiting block 7 is circular in shape and arranged along the circumference of the adjusting block 5. The spring 4 is sleeved on the outer wall of the adjusting block 5 and fixedly connected to the limiting block 7. The outer wall of the adjusting block 5 is threadedly connected to the mounting base 2. A hexagonal adjusting groove 8 is provided at the end of the adjusting block 5 away from the pressing base 6. The hexagonal adjusting groove 8 allows the adjusting block 5 to rotate relative to the mounting base 2. The limiting block 7 on the outer wall of the adjusting block 5 can axially limit the spring 4, preventing the spring 4 from radially shifting or falling off during the extension and contraction process, ensuring that the spring force of the spring 4 is always along the length direction of the shuttle body 1, and ensuring stable and reliable pressing force on the yarn tube. The adjusting block 5 is threadedly connected to the mounting base 2 and has a hexagonal adjusting groove 8. By rotating the adjusting block 5, its axial position in the mounting base 2 can be changed, thereby adjusting the preload of the spring 4 and achieving precise control of the pressing force on the yarn tube. The hexagonal adjusting groove 8 is compatible with general tools, facilitating quick operation and improving equipment debugging efficiency.

[0028] The clamping seat 6 includes a bearing 61 and a clamping block 62, which are coaxially rotatably connected. The clamping block 62 is connected to the weft yarn tube 3, and the bearing 61 is fixedly connected to the spring 4. Because the bearing 61 and clamping block 62 are coaxially rotatably connected, when the yarn tube rotates to release the weft, the clamping block 62 can rotate synchronously with the yarn tube. The bearing 61 reduces the relative friction between the clamping block 62 and the spring 4, lowers the rotational resistance of the yarn tube, avoids yarn tube wear or weft tension fluctuations due to excessive friction, and ensures smooth yarn delivery.

[0029] The clamping block 62 has a coaxial connecting groove 9. An annular block 10 is fixed to one end of the clamping block 62 away from the spring 4. The annular block 10 is circumferentially arranged along the outer edge of the clamping block 62, with its outer side shaped like a frustum and its inner side chamfered. The weft yarn tube 3 is connected to the clamping block 62 at a position that matches the shape of the clamping block 62. The matching shape of the connecting groove 9 and the annular block 10 of the clamping block 62 with the connection position of the yarn tube allows for a fitted connection between the yarn tube and the clamping block 62, enhancing their fit and connection strength, preventing relative sliding between the yarn tube and the clamping block 62 during high-speed rotation, and improving the positioning accuracy of the yarn tube installation.

[0030] The clamping seat 6 is equipped with a displacement sensor. When the displacement sensor detects axial vibration in the clamping seat 6, it generates a monitoring signal and sends it to the user's smart terminal, such as a mobile phone. The displacement sensor in the clamping seat 6 can monitor its axial vibration in real time. When abnormal vibration occurs, it generates a signal promptly, allowing operators or the control system to quickly detect equipment malfunctions (such as spring 4 failure, yarn tube wear, etc.), enabling predictive maintenance and reducing downtime losses due to sudden failures.

[0031] The clamping seat 6 is made of silicon carbide ceramic composite material, which has high hardness, high wear resistance and high temperature resistance. It can withstand the friction and impact when the yarn tube rotates at high speed, extending the service life of the clamping seat 6. At the same time, its corrosion resistance can adapt to dust, moisture and other elements in the weaving environment, reducing component wear.

[0032] The shuttle body 1 is provided with an elastic baffle 11, which abuts against the outer wall of the weft yarn tube 3. The elastic baffle 11 abuts against the outer wall of the yarn tube, which can form an auxiliary limit on the yarn tube in the radial direction. Combined with the axial clamping force of the spring shaft assembly, it forms a double fixation in the axial and radial directions, further suppressing the radial sway of the yarn tube. Especially when the shuttle moves at high speed, it can reduce the deviation of the yarn tube caused by centrifugal force and improve the overall structural stability.

[0033] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
