Description

Technical Field

[0001] This utility model relates to the technical field of circular looms, and in particular to a shuttle for a circular loom and a circular loom. Background Technology

[0002] In existing circular looms, the shuttle drives the weft spindle in a circular motion on the gate assembly, weaving through the warp threads that intersect at different heights, thus achieving weaving. However, after a period of use, the weft yarn on the spindle will be used up, and the machine needs to be stopped to replace it. Since a circular loom typically has four, six, or more shuttles, the speed at which workers replace the weft spindles affects the production efficiency of the weaving company.

[0003] Existing circular looms generally use shuttles to position the weft spindles. Existing shuttles generally include a first tube seat and a second tube seat. The first tube seat and the second tube seat rotate relative to the shuttle body. The two ends of the tube body of the weft spindle are respectively fitted onto the first tube seat and the second tube seat. After the weft yarn is drawn, the weft spindle rotates to unwind the weft yarn and realize weaving. The first tube seat can also be close to the second tube seat relative to the shuttle body to clamp the tube body of the weft spindle, or it can be far away from the second tube seat relative to the shuttle body to disassemble the weft spindle and install a new weft spindle.

[0004] Because the weft spindle rotates at a relatively high speed during the circular loom weaving process, it will vibrate under the pressure released by the weft yarn. In order to ensure the reliability of the weft spindle tube after it is clamped by the first and second tube seats and to prevent the weft tube from detaching from the shuttle body, a spring with a large stiffness coefficient is installed on the first tube seat. When a spring with a large stiffness coefficient is used to ensure the stability of the clamping of the weft spindle by the first and second tube seats, the operator needs to use a lot of force to slide the first tube seat away from the second tube seat and keep the first tube seat away from the second tube seat in order to replace the new weft spindle. This greatly increases the difficulty for the operator to replace the weft spindle. Utility Model Content

[0005] The purpose of this invention is to provide a shuttle for a circular loom and a circular loom, which solves the problem of increased difficulty in replacing weft spindles due to the large spring stiffness coefficient, reduces the difficulty of replacing weft spindles, and thus improves the efficiency of workers in replacing weft spindles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shuttle for a circular loom, comprising a shuttle frame, wherein a first tube seat and a second tube seat are provided on the shuttle frame, the first tube seat and the second tube seat are spaced apart to form an installation space for the weft tube, the first tube seat comprising a seat body and a sleeve, the sleeve being slidably disposed on the seat body along the axial direction of the weft tube, the seat body being provided with a limiting rod extending along the axial direction of the weft tube, the limiting rod being provided with a locking rod, the seat body having a first locking position and a second locking position, when the locking rod is in the first locking position, the limiting rod will abut against the sleeve to stabilize the weft tube between the sleeve and the second tube seat, when the locking rod is in the second locking position, the sleeve slides relative to the mounting seat to disassemble the weft tube between the sleeve and the second tube seat.

[0007] After adopting the above technical solution, this utility model has the following advantages: A first tube seat and a second tube seat are installed on the shuttle frame, forming an installation space for the weft tube between them, ensuring that the weft tube can be installed on the shuttle frame; the first tube seat is configured as a combination of a seat body and a sleeve, with the sleeve axially slidingly installed with the seat body. The axial size of the installation space is adjusted by sliding the sleeve, facilitating the installation and disassembly of the weft tube and reducing the difficulty for workers replacing the weft tube; a limiting rod is provided on the seat body, and a locking rod is provided on the limiting rod. The engagement or unlocking of the limiting rod with the sleeve is adjusted by switching the locking rod between the first and second locking positions; specifically, when the locking rod is in the first locking position, the limiting rod abuts against the back of the sleeve. On one end face away from the second tube seat, a barrier is formed against the sleeve, effectively preventing the sleeve from sliding axially during the operation of the weft tube and affecting its stability. When the locking rod is changed from the first locking position to the second locking position, the limiting rod moves backward toward one end of the sleeve and no longer abuts against the end face of the sleeve away from the second sleeve. The worker can manually drive the sleeve to slide axially away from the second sleeve, which facilitates the disassembly and installation of the weft tube. In the above scheme, an elastic element can be installed between the seat and the sleeve, or it can be omitted. When an elastic element is installed, an elastic element with a relatively small stiffness coefficient can be selected to facilitate the worker to drive the sleeve away from the second tube seat, improve the efficiency of the worker in replacing and installing the weft tube, and reduce the difficulty of the worker in disassembling and installing the weft tube.

[0008] Furthermore, the seat body includes a mounting base and a limiting seat detachably disposed on the mounting base, with the limiting rod, the first locking position and the second locking position both disposed on the limiting seat.

[0009] Furthermore, the limiting seat is provided with a through hole extending along the weft tube axis, a first locking groove, and a second locking groove. The limiting rod is slidably disposed in the through hole. The first locking groove and the second locking groove are connected. The length of the first locking groove along the weft tube axis is less than the length of the second locking groove along the weft tube axis. The ends of the first locking groove and the second locking groove near the sleeve are flush. The end of the first locking groove away from the sleeve is the first locking position, and the end of the second locking groove away from the sleeve is the second locking position.

[0010] Furthermore, the limiting seat has a protrusion extending toward the sleeve, the protrusion being located between the first locking groove and the second locking groove.

[0011] Furthermore, the locking rod is perpendicular to the limiting rod, and the locking rod protrudes from the outer wall of the limiting seat to form an operating part.

[0012] Furthermore, the limiting seat includes a mounting part connected to the mounting base. The mounting part is provided with a strip-shaped adjustment hole extending along the axial direction of the weft tube. Fasteners pass through the strip-shaped adjustment hole and are fastened to the mounting base, thus securing the mounting part to the mounting base.

[0013] Furthermore, the end of the limiting rod away from the sleeve is provided with a blocking part, and a first elastic element with bias blocking part is provided between the blocking part and the seat body.

[0014] Furthermore, the seat body is provided with a connecting rod, the sleeve is sleeved on the connecting rod, and a second elastic element that biases the sleeve is provided between the seat body and the sleeve.

[0015] Furthermore, the end of the connecting rod away from the mounting base is provided with a blocking block to prevent the sleeve from detaching from the connecting rod.

[0016] To achieve the above objectives, the present invention adopts the following technical solution: a circular loom, including a gate assembly and a shuttle, wherein the shuttle performs circular motion within the gate assembly, and the shuttle is the aforementioned shuttle for a circular loom.

[0017] As can be seen from the above, the shuttle for a circular loom and the circular loom provided by this utility model, through the cooperation of the limiting rod and the locking rod, can stably fix the weft tube when the locking rod is switched to the first locking position, and allow the sleeve to slide to quickly disassemble the weft tube when switched to the second locking position. During the process of disassembling and installing the weft tube, the worker does not need to overcome the elastic force of the high-strength spring, which has the advantages of reducing the difficulty of operation, improving the replacement efficiency and reducing the wear of parts.

[0021] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a shuttle for a circular loom, including a shuttle frame 1. The shuttle frame 1 is provided with a first tube seat 2 and a second tube seat 3. The first tube seat 2 and the second tube seat 3 are spaced apart to form an installation space for the weft tube 4. The weft tube 4 is installed through this installation space, which facilitates its installation and also allows it to rotate and unwind during the operation of the circular loom. Figure 3As shown, the first tube seat 2 includes a seat body and a sleeve 22. The sleeve 22 is slidably mounted on the seat body along the axial direction of the weft tube 4. The axial sliding of the sleeve 22 facilitates the disassembly and installation of the weft tube 4 by workers. The mounting seat 21 is provided with a limiting rod 211 extending along the axial direction of the weft tube 4. The limiting rod 211 can slide relative to the seat body in the axial direction of the weft tube 4. The limiting rod 211 is provided with a locking rod 212. The seat body has a first locking position and a second locking position. The first locking position means that the locking rod 212 is in the position that restricts the movement of the limiting rod 211. At this time, the front end of the limiting rod 211 contacts the end face of the sleeve 22, preventing the sleeve 22 from retracting; when the locking rod 212 is in the second locking position, the limiting rod 211 releases the constraint on the sleeve 22, and the sleeve 22 can slide freely along the axial direction of the weft tube 4; when the locking rod 212 is in the first locking position, the limiting rod 211 will abut against the sleeve 22 to stabilize the weft tube 4 between the sleeve 22 and the second tube seat 3; when the locking rod 212 is in the second locking position, the sleeve 22 slides relative to the seat body to disassemble the weft tube 4 between the sleeve 22 and the second tube seat 3; The positioning lever 211 achieves contact or separation with the sleeve 22 by sliding along the axial direction of the weft tube 4. Specifically, when installing the weft tube 4 between the sleeve 22 and the second tube seat 3, after ensuring that the locking lever 212 is in the second locking position, the worker drives the sleeve 22 to slide away from the second tube seat 3. After placing the weft tube 4 between the sleeve 22 and the second tube seat 3, the locking lever 212 is switched from the second locking position to the first locking position, so that the limiting lever 211 abuts against the end face of the sleeve 22 away from the weft tube 4, effectively... To prevent the sleeve 22 from moving away from the second tube seat 3 during the vibration of the weft tube 4 and affecting the stability of the weft tube 4, in this embodiment, the position of the limiting rod 211 is adjusted by the locking rod 212. The limiting rod 211 restricts the position of the sleeve 22 after the weft tube 4 is installed. An elastic element with a small stiffness coefficient can be selected or no elastic element can be used, thereby reducing the difficulty for workers to replace the weft tube 4, improving the replacement efficiency of the weft tube 4, and also reducing the wear between the sleeve 22 and the mounting seat 21, thus increasing the service life of the shuttle used in the circular loom.

[0023] In another embodiment, such as Figure 3 and Figure 4 As shown, the base includes a mounting base 21 and a detachable limiting seat 23 on the mounting base 21. The sleeve 22 is located on the mounting base 21, and the limiting rod 211, the first locking position, and the second locking position are all located on the limiting seat 23. The limiting seat 23 and the mounting base 21 are connected in a separable manner, which can be achieved by bolt fixing or a snap-fit ​​structure, so that the limiting seat 23 can be disassembled and assembled independently of the mounting base 21. Specifically, when the size of the weft tube 4 changes slightly, without replacing the shuttle frame 1, the limiting seat 23 can be removed from the mounting base 21 and replaced with a limiting seat 23 that matches the size of the weft tube 4, so that the weft tube 4 can be installed between the sleeve 22 and the second tube seat 3, thereby improving the applicability of the shuttle frame 1.

[0024] To facilitate the disassembly of the limiting seat 23, such as Figure 4 As shown, the limiting seat 23 includes a mounting part 231 connected to the mounting base 21. The mounting part 231 can be formed by stamping metal sheet. The mounting part 231 has a strip-shaped adjustment hole 2311 extending axially along the weft yarn tube 4. Fasteners 2312 pass through the strip-shaped adjustment hole 2311 and are securely connected to the mounting base 21, thus securing the mounting part 231 to the mounting base 21. Specifically, the mounting part 231 forms a slidable connection with the mounting base 21 through the strip-shaped adjustment hole 2311. When the position of the limiting seat 23 needs to be adjusted... First, loosen the fastener 2312, then move the mounting part 231 along the extension direction of the strip-shaped adjustment hole 2311, thereby driving the limiting rod 211 and the locking rod 212 to move axially along the weft tube 4 as a whole; after adjustment, tighten the fastener 2312 again to fix the relative position of the mounting part 231 and the mounting seat 21; this adjustment process allows the limiting rod 211 to adapt to weft tubes 4 of different lengths, ensuring that the clamping distance between the sleeve 22 and the second tube seat 3 matches the size of the weft tube 4; reducing the number of times the limiting seat 23 is disassembled.

[0025] In this embodiment, as Figure 4As shown, the limiting seat 23 is provided with a through hole 232 extending along the axial direction of the weft tube 4, a first locking groove 233, and a second locking groove 234. The limiting rod 211 is slidably disposed in the through hole 232, which facilitates the movement of the limiting rod 211 in the axial direction of the weft tube 4 to abut against or disengage from the sleeve 22. The first locking groove 233 and the second locking groove 234 are connected to each other, which facilitates the changing position of the locking rod 212 in the first locking groove 233 and the second locking groove 234. The length of the first locking groove 233 in the axial direction of the weft tube 4 is less than that of the second locking groove 234. The length of the locking groove 234 along the axial direction of the weft tube 4 is such that the first locking groove 233 and the second locking groove 234 are flush with the ends of the sleeve 22. The end of the first locking groove 233 away from the sleeve 22 is the first locking position, and the end of the second locking groove 234 away from the sleeve 22 is the second locking position. Specifically, when the locking rod 212 is at the far end of the first locking groove 233, the limiting rod 211 is forcibly constrained in the first locking position. At this time, the front end of the limiting rod 211 abuts against the sleeve 22, preventing the sleeve 22 from sliding and the weft tube 4 is stably clamped. When the weft tube 4 needs to be replaced, the worker moves the locking rod 212 from the first locking groove 233 to the entrance of the second locking groove 234 and moves the locking rod 212 to the second locking position. At this time, the limiting rod 211 contacts the axial limit of the sleeve 22, and the worker can move the sleeve 22 axially away from the second tube seat 3 to form sufficient space for the disassembly and installation of the weft tube 4. The length of the second locking groove 234 is greater than the length of the first locking groove 233, and the first locking groove 233 and the second locking groove 234 are flush with the end facing the sleeve 22. This ensures that when the locking rod 212 is in the first locking groove 233, the limiting rod 211 can be in the state of locking the sleeve 22, so as to prevent the sleeve 22 from sliding axially during the operation of the weft tube 4 and affecting the stability of the weft tube 4. At the same time, it also ensures that when the locking rod 212 is in the second locking groove 234, the limiting rod 211 can slide in a direction away from the second tube seat 3 and can slide to the rear side where the limiting rod 211 is in the locked state. This ensures that the sleeve 22 can slide axially at this time to unlock the axial contact with the weft tube 4, thereby realizing the disassembly and replacement of the weft tube 4. This embodiment effectively solves the problem of difficulty in replacing the weft tube 4 caused by the large spring stiffness coefficient. The worker only needs to push the locking rod 212 to complete the switching between the clamping state and the replacement state. The operation steps are reduced and no continuous force is required, which significantly reduces the time cost and labor intensity of replacing the weft tube 4. Meanwhile, the limiting of the first locking groove 233 and the second locking groove 234 ensures that the sleeve 22 always maintains a stable clamping state during the weaving process, avoiding displacement of the weft tube 4 due to vibration.

[0026] To improve the stability of the locking lever 212 in the first and second locking slots, such as Figure 4As shown, the limiting seat 23 has a protrusion 236 extending toward the sleeve 22, and the protrusion 236 is located between the first locking groove 233 and the second locking groove 234. Specifically, the first locking groove 233 and the second locking groove 234 are connected by a connecting groove 235. The protrusion 236 is located on the groove wall of the connecting groove 235 on the side away from the sleeve 22, and the protrusion 236 extends toward the sleeve 22. The protrusion 236 forms a physical obstruction in the movement path of the locking rod 212. Specifically, when the locking rod 212 needs to switch from the first locking position to the second locking position, the worker needs to apply external force to make the locking rod 212 slide along the extension direction of the first locking groove 233. At this time, the protrusion 236 forms resistance to the movement of the locking rod 212. When the locking rod 212 passes the protrusion 236, the resistance disappears and it enters the second locking groove 234. During this process, the protrusion 236 forces the locking lever 212 to move in a preset direction, preventing it from deviating from the target locking position due to vibration or accidental contact. At the same time, the cooperation between the protrusion 236 and the locking groove provides tactile feedback, allowing the worker to judge by touch whether the locking lever 212 has completed the position switch. This prevents the locking lever 212 from entering the second locking groove 234 from the first locking groove 233 during the vibration of the weft tube 4, thus affecting the stability of the weft tube 4 and ensuring the clarity of the locking state.

[0027] To facilitate worker operation of the locking lever 212 to switch between the first locking position and the second locking position, such as... Figure 4 As shown, the locking rod 212 is perpendicular to the limiting rod 211, and the locking rod 212 protrudes from the outer wall of the limiting seat 23 to form the operating part 2121. Specifically, by setting the locking rod 212 perpendicular to the limiting rod 211, the contact area between the locking rod 212 and the groove wall of the first locking groove 233 or the second locking groove 234 is increased, thereby improving the stability of the locking rod 212 when locked. The operating part 2121 is the protruding section of the locking rod 212 that extends outward beyond the side wall of the limiting seat 23. Specifically, it can be implemented by machining the rod end into a flat handle or a spherical end. This structure allows the operator to directly apply pushing or pulling force by touching the operating part 2121 with their fingers, and can complete the switching of the locking state without the aid of tools. The existence of the operating part 2121 enables manual operation, and the orthogonally arranged locking rod 212 eliminates the overlap between the operating direction and the movement trajectory of the component, significantly reducing the probability of misoperation.

[0028] In this embodiment, as Figure 3 and Figure 5As shown, to facilitate the installation of the limiting rod 211 and locking rod 212 with the limiting seat 23, the limiting rod 211 is provided with a threaded hole perpendicular to the limiting rod 211, and the outer wall of one end of the locking rod 212 is provided with threads. During installation, the limiting rod 211 is first inserted into the through hole 232, and the position of the limiting rod 211 is moved so that the threaded hole can be seen from the first locking groove 233 or the second locking groove 234. Then, the locking rod 212 is inserted from the first locking groove 233 or the second locking groove 234 and threadedly connected to the threaded hole, thereby fastening the locking rod 212 and the limiting rod 211 together.

[0029] In another embodiment, such as Figure 5 As shown, the end of the limiting rod 211 away from the sleeve 22 is provided with a blocking part 2111, and a first elastic member 2112 of the bias blocking part 2111 is provided between the blocking part 2111 and the seat body. Specifically, the first elastic member 2112 is provided between the blocking part 2111 and the limiting seat 23. The blocking part 2111 is provided at the end of the limiting rod 211 and its radial dimension is larger than that of the main body of the limiting rod 211. Specifically, it can be implemented by welding or integrally forming an annular boss. Its function is to limit the sliding stroke of the limiting rod 211 and prevent the limiting rod 211 from completely disengaging from the mounting seat 21. One end of the first elastic member 2112 abuts against the mounting seat 21 and the other end abuts against the blocking part 2111, so that the limiting rod 211 tends to move away from the sleeve 22, ensuring the stability of the locking rod 212 in the first locking position or the second locking position.

[0030] To ensure that the sleeve 22 can be reset and the second tube seat 3 can be used to stabilize the weft tube 4, a connecting rod 24 is provided on the seat body. Specifically, the connecting rod 24 is set on the mounting base 21, such as... Figure 5As shown, the sleeve 22 is fitted onto the connecting rod 24, and the sleeve slides along the axial direction of the weft tube 4 on the connecting rod 24. A second elastic element 241 biasing the sleeve 22 is provided between the mounting base 21 and the sleeve 22. One end of the second elastic element 241 abuts against the mounting base 21, and the other end abuts against the end face of the sleeve 22 away from the second tube seat 3. When it is necessary to disassemble the weft tube 4, the blocking effect of the limiting rod 211 on the sleeve 22 is first released by the locking rod 212. Then, the sleeve 22 is pushed in the direction away from the second tube seat 3. The sleeve 22 compresses the second elastic element 241 so that the sleeve 22 slides on the connecting rod 24, causing the weft tube 4 to disengage from the second tube seat 3. When the weft tube 4 disengages from the second tube seat 3, Afterwards, the weft tube 4 is deflected and removed from the sleeve 22, thus disassembling the weft tube 4. When a new weft tube 4 needs to be installed, the sleeve 22 is brought into contact with the mounting base 21 through the weft tube 4. When the weft tube 4 can fit into the second tube base 3, the weft tube 4 is deflected so that it can fit into the second tube base 3. The sleeve 22 and the weft tube 4 move towards the second tube base 3 under the action of the second elastic element 241, so that the weft tube 4 fits into the second tube base 3. The second elastic element 241 allows the weft tube 4 to maintain a preliminary fit with the second tube base 3. Then, the position of the sleeve 22 is limited by the limiting rod 211, thereby ensuring the stability of the weft tube 4 on the sleeve 22 and the second tube base 3.

[0031] In this embodiment, as Figure 5 As shown, the end of the connecting rod 24 away from the mounting base 21 is provided with a blocking block 242 to prevent the sleeve 22 from detaching from the connecting rod 24; this prevents the sleeve 22 from detaching from the connecting rod 24 under the abutment of the second elastic member 241, thereby improving the stability of the sleeve 22.

[0032] In another embodiment, the present invention also provides a circular loom, including a gate assembly and a shuttle. The shuttle performs circular motion within the gate assembly, and the shuttle is any of the circular loom shuttles described in the above embodiments. When the above-mentioned circular loom shuttle is applied to a circular loom, when the sleeve 22 and the second tube seat 3 axially fix the weft tube 4, the first locking position blocks the locking rod 212, thereby blocking the limiting rod 211 against the sleeve 22. This effectively prevents the weft tube 4 from shaking during the yarn release process, which would affect the stability of the sleeve 22 and thus the stability of the weft tube 4. When it is necessary to disassemble and replace the weft tube 4, the locking rod 212 is switched from the first locking position to the second locking position, so that the limiting rod 211 is separated from the sleeve 22, and the sleeve 22 can slide axially on the weft tube 4, thus facilitating the disassembly and replacement of the weft tube 4. This improves the replacement efficiency of the weft tube 4, shortens the downtime of the circular loom, and thus improves the overall production efficiency of the circular loom.

[0033] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
