Description

Technical Field

[0001] The present invention relates to the technical field of circular looms, in particular to a shuttle for a circular loom and a circular loom. Background Art

[0002] In existing circular looms, the shuttle drives the weft yarn spindle to make a circular motion on the door ring assembly and shuttles through the warp threads that open and close up and down, thereby realizing weaving. After the weft yarn on the weft yarn spindle is used up after a period of use, it needs to be stopped for replacement. Generally, a circular loom has four or six or more shuttles. Therefore, the speed at which workers replace the weft yarn spindle will affect the production efficiency of knitting enterprises.

[0003] Existing circular looms generally use a shuttle to position the weft yarn spindle. 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 yarn spindle are respectively sleeved on the first tube seat and the second tube seat. After the weft yarn is pulled, the weft yarn spindle rotates to unwind the weft yarn to realize weaving. The first tube seat can also move closer to the second tube seat relative to the shuttle body to clamp the tube body of the weft yarn spindle, or move away from the second tube seat relative to the shuttle body to disassemble the weft yarn spindle and install a new weft yarn spindle.

[0004] Due to the relatively fast rotation of the weft yarn spindle during the weaving process of the circular loom, the weft yarn spindle will vibrate under the action of the pressure of the weft yarn release. In order to ensure that the tube body of the weft yarn spindle can be reliably clamped by the first tube seat and the second tube seat and not separated from the shuttle body, a spring with a relatively large stiffness coefficient is provided on the first tube seat. When a spring with a relatively large stiffness coefficient is used to ensure the stability of clamping the weft yarn spindle by the first tube seat and the second tube seat, when replacing the weft yarn spindle, the operator needs to use a relatively large force to slide the first tube seat in the direction away from the second tube seat, and also needs to keep the first tube seat away from the second tube seat to replace the new weft yarn spindle, which greatly increases the difficulty for the operator to replace the weft yarn spindle. Summary of the Invention

[0005] The object to be achieved by the present invention is to provide a shuttle for a circular loom and a circular loom, solve the problem of the increased difficulty of replacing the weft yarn spindle due to the large stiffness coefficient of the spring, reduce the difficulty of replacing the weft yarn spindle, and thereby improve the efficiency of workers replacing the weft yarn spindle.

[0006] To achieve the above object, the present invention adopts the following technical solution: A shuttle for a circular loom, comprising a shuttle frame, on which a first tube seat and a second tube seat are provided. The first tube seat and the second tube seat are spaced apart to form an installation space for a weft yarn tube. An installation seat is provided on the shuttle frame. The first tube seat is arranged on the installation seat and can axially slide relative to the installation seat. The installation seat is provided with a locking position and an unlocking position. A connecting member is hinged on the installation seat. One end of the connecting member away from the installation seat is connected to the first tube seat. A plug-in member is provided on the connecting member. Rotate the connecting member so that the plug-in member cooperates with the locking position or the unlocking position. When the plug-in member cooperates with the locking position, the first tube seat and the second tube seat axially fix the weft yarn tube. When the plug-in member cooperates with the unlocking position, the first tube seat moves away from the second tube seat to release the axial fixation of the weft yarn tube.

[0007] After adopting the above technical solution, the present invention has the following advantages: The weft yarn tube is installed through the installation space formed between the first tube seat and the second tube seat provided on the shuttle frame, which facilitates the installation of the weft yarn tube between the first tube seat and the second tube seat and also facilitates the unwinding of the yarn; The sliding setting of the first tube seat axially on the installation seat facilitates adjusting the axial length of the installation space through the axial sliding of the first tube seat, and thus facilitates the installation or disassembly of the weft yarn tube between the first tube seat and the second tube seat; Through the hinged connection of the connecting member and the plug-in member provided on the connecting member, when the plug-in member is matched with the locking position, the first tube seat and the second tube seat axially fix the weft yarn tube, which is convenient for the stable installation of the weft yarn tube and ensures that the weft yarn tube can be stably installed on the shuttle frame. During the process of switching the plug-in member from the locking position to the unlocking position, rotate the connecting member in the direction away from the second tube seat until the plug-in member cooperates with the unlocking position. During the rotation of the connecting member, the first tube seat is driven to move away from the second tube seat, thereby releasing the axial fixation of the weft yarn tube by the first tube seat and the second tube seat, facilitating the removal of the weft yarn tube after the unwinding is completed from the first tube seat and the second tube seat and replacing it with a new weft yarn tube; After the plug-in member cooperates with the locking position, the connecting member remains relatively stationary relative to the installation seat, so that the first tube seat is restricted axially, improving the stability of the first tube seat on the installation seat and avoiding the influence of the jitter generated during the rotation and unwinding of the weft yarn tube on the first tube seat on the stability of the weft yarn tube; When it is necessary to disassemble the weft yarn tube, switch the plug-in member to cooperate with the unlocking position, so that the connecting member drives the first tube seat to axially move away from the second tube seat, facilitating the disassembly and replacement of the weft yarn tube. Compared with the prior art using a spring with a relatively large spring constant, through the cooperation of the plug-in member and the locking position, the axial stability of the first tube seat is improved, and thus the stability of the weft yarn tube is improved; Through the cooperation of the plug-in member and the unlocking position, the stability of the first tube seat during the disassembly and replacement of the weft yarn tube is improved, effectively avoiding the tendency of the first tube seat to move towards the second tube seat and affecting the efficiency of the worker in disassembling and replacing the weft yarn tube.

[0008] Furthermore, the connecting piece is provided with a long guide hole, and the plug-in piece includes a plug-in portion, which is slidably connected to the long guide hole so that the plug-in portion cooperates with the locking position or the unlocking position, or the plug-in portion is disengaged from the locking position or the unlocking position.

[0009] By adopting the above-mentioned technical solution, a long guide hole is set on the connecting part, and the long guide hole provides guidance for the process of the plug-in part engaging with or disengaging from the locking position and the unlocking position, so that workers can drive the plug-in part to slide and engage with the locking position and the unlocking position, or drive the plug-in part to slide and disengage from the locking position and the unlocking position, ensuring that workers can achieve the fixing, disassembly and replacement of the weft yarn tube by switching the position of the plug-in part.

[0010] Furthermore, the plug-in portion includes a guide end and a plug-in end distributed along the plug-in direction. The plug-in portion cooperates with the locking position or the unlocking position, and the guide end fits against the hole wall of the guide long hole to guide the sliding of the plug-in end.

[0011] By adopting the above-mentioned technical solution, the plug-in part is set in the form of a plug-in end and a guide end. By cooperating with the plug-in end and the locking position and the unlocking position, it is ensured that the plug-in part can fix the first tube seat in the axial direction after cooperating with the locking position or the unlocking position, thereby improving the stability of the plug-in end in the locking position or the unlocking position. The guide end is arranged to fit the hole wall of the guide long hole to ensure the stability of the plug-in part sliding in the guide long hole, thereby avoiding shaking of the plug-in part when sliding and affecting the coordination efficiency of the plug-in end with the locking position or the unlocking position.

[0012] Furthermore, the thickness of the plug-in end gradually decreases along the plug-in direction, the locking position is a locking groove, and the unlocking position is an unlocking groove, and the shape of the plug-in portion is adapted to the shapes of the locking groove and the unlocking groove.

[0013] By adopting the above-mentioned technical solution, the thickness of the plug-in end is gradually reduced along the plug-in direction, and the shape of the plug-in part is adapted to the shape of the locking groove and the unlocking groove, ensuring that when the plug-in end is plugged into the locking groove or the unlocking groove, the smaller end is plugged into the larger end of the locking groove or the unlocking groove first, ensuring that the plug-in end can be plugged into the locking groove or the unlocking groove more accurately, thereby improving the accuracy of plug-in, reducing the accuracy of the worker's operation, and thus reducing the difficulty of the worker's operation.

[0014] Furthermore, a first elastic member is provided between the plug-in portion and the connector, and the first elastic member biases the plug-in portion toward a locking position or an unlocking position to maintain the fit.

[0015] By adopting the above-mentioned technical solution, a first elastic member is arranged between the plug-in part and the connecting part, and the plug-in part is biased toward the locking position or the unlocking position by the first elastic member, thereby ensuring the stability of the plug-in part in cooperation with the locking position or the unlocking position, thereby improving the axial stability of the first tube seat.

[0016] Furthermore, the connecting member includes a mounting rod and a connecting rod, the mounting rod is hinged to the mounting seat, the long guide hole is provided on the mounting rod, one end of the connecting rod is connected to the first tube seat, and the other end is hingedly connected to the end of the mounting rod away from the mounting seat, and the plug-in member also includes an operating part, one end of the operating part is connected to the plug-in part, and the other end extends to the end surface of one end of the mounting seat to form a gripping part.

[0017] By adopting the above-mentioned technical solution, the connecting piece is arranged in the form of a mounting rod and a connecting rod, so that the worker can drive the axial movement of the first tube seat through the connecting piece when installing or removing the weft rod; one end of the operating part is connected to the plug-in part, and the other end passes through the mounting rod to form a holding part. When the plug-in part needs to be switched from the locked position to the unlocked position, the worker holds the holding part and pulls the holding part away from the mounting seat to drive the plug-in part out of the locked position or the unlocked position; the setting of the holding part makes it convenient for the worker to hold it stably and drive the plug-in part to slide in the guide long hole, thereby making it convenient for the worker to drive the second tube seat to axially fix the weft tube or remove and replace the weft tube.

[0018] Furthermore, the mounting base includes a second base body and a first base body for installing the first pipe base, the second base body includes a support and a connecting plate arranged on the support, the connecting plate has two pieces, and an accommodating space for accommodating the connecting piece is formed between the two connecting plates. The accommodating space avoids the rotation of the connecting piece, and locking positions and unlocking positions are provided on the two connecting plates, and the connector cooperates with the two locking positions or the two unlocking positions at the same time.

[0019] By adopting the above-mentioned technical solution, an accommodating space is formed by two connecting plates, and the connector is accommodated in the accommodating space to improve the stability of the connector during rotation and prevent the connector from shaking or deflecting; in the rotation direction of the connector, the accommodating space also avoids the connector to ensure that the connector can rotate to switch the cooperation between the connector and the unlocking position or the locking position; locking positions and unlocking positions are set on both connecting plates, and the connector cooperates with the locking positions of the two connecting plates at the same time, or cooperates with the two unlocking positions at the same time, so that both sides of the connector are restricted by the locking position or the unlocking position, thereby improving the stability of the connector after insertion, and thereby improving the stability of the first tube seat when fixing the weft yarn tube or removing the weft yarn tube.

[0020] Furthermore, a sleeve is provided between the two connecting plates to form an accommodating space between the two connecting plates, and the two connecting plates and the sleeve are fastened to the bracket by a first fastener.

[0021] By adopting the above-mentioned technical solution, the accommodating space is formed by a sleeve arranged between the two connecting plates, ensuring the stability of the size of the accommodating space, avoiding the shaking of the connecting plates during the circular motion of the shuttle rack, which affects the stability of the size of the accommodating space, and then affects the stability of the connecting piece. The first fastener fastens the two connecting plates and the sleeve to the bracket, improves the stability of the two connecting plates, and then improves the stability of the connection between the two connecting plates and the bracket.

[0022] Further, fixing rods are provided on the two connecting plates and located below the locking position, and the connecting member is rotatably connected to the fixing rods.

[0023] By adopting the foregoing technical solution, by providing fixing rods on the two connecting plates, the strength of the two connecting plates is improved, effectively avoiding the possibility of damage to the two connecting plates during the circumferential movement of the shuttle frame. Moreover, the fixing rods are located below the locking position to ensure that the plug-in member can cooperate with the locking position or the unlocking position during the rotation of the connecting member. The connecting rod is rotatably connected to the fixing rod to ensure that the connecting member can rotate smoothly in the accommodating space, reducing the difficulty for workers to replace the weft yarn tube.

[0024] To achieve the above object, the present invention also adopts the following technical solution: a circular loom, including a door ring assembly and a shuttle, the shuttle makes a circular movement within the door ring assembly, and the shuttle is the shuttle for the circular loom as described above.

[0025] By adopting the foregoing technical solution, applying the foregoing shuttle for the circular loom to the circular loom, when the first tube seat and the second tube seat axially fix the weft yarn tube, the stability of the first tube seat is improved through the cooperation between the plug-in member and the locking position, effectively avoiding the shaking of the weft yarn tube during the process of releasing the yarn, which affects the stability of the first tube seat and further affects the stability of the weft yarn tube; when it is necessary to disassemble and replace the weft yarn tube, the plug-in member cooperating with the locking position is switched to cooperate with the unlocking position. During the switching process, the first tube seat is driven away from the second tube seat by the connecting member, thus facilitating the disassembly and replacement of the weft yarn tube; the cooperation between the plug-in member and the unlocking position improves the stability of the first tube seat during the disassembly process, avoiding the tendency of the first tube seat to reset, which affects the efficiency of the worker to disassemble and replace the weft yarn tube, and further reducing the downtime of the circular loom.

[0034] The technical solutions of the present invention will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to the actual situation. For the same or similar concepts or processes, they may not be described again in some embodiments.

[0035] As Figure 1 shown, the present invention provides a shuttle for a circular loom, which includes a shuttle frame 1. A first tube seat 2 and a second tube seat (the second tube seat is not shown in the drawings) are provided on the shuttle frame 1. The first tube seat 2 and the second tube seat are spaced apart to form an installation space for the weft yarn tube. The weft yarn tube is accommodated through the installation space, which facilitates the installation of the weft yarn tube. An installation seat 3 is provided on the shuttle frame 1. The first tube seat 2 is arranged on the installation seat 3 and can axially slide relative to the installation seat 3. The axially sliding arrangement of the first tube seat 2 facilitates making way for the installation, disassembly, and replacement of the weft yarn tube through the axial movement of the first tube seat 2, which is convenient for workers to disassemble and replace the weft yarn tube. In this embodiment, as Figure 1 shown, a locking position 31 and an unlocking position 32 are provided on the installation seat 3. The locking position 31 is located between the second tube seat and the unlocking position 32. A connecting member is hinged on the installation seat 3. One end of the connecting member away from the installation seat 3 is connected to the first tube seat 2. A plug-in member 34 is provided on the connecting member. Rotate the connecting member to make the plug-in member 34 cooperate with the locking position 31 or the unlocking position 32. A plug-in member 34 is provided on the connecting member. Rotate the connecting member to make the plug-in member 34 cooperate with the locking position 31 or the unlocking position 32.

[0036] As Figure 2 shown, when the connector 34 is engaged with the locking position 31, the first socket 2 and the second socket axially fix the weft yarn tube. When the weft yarn tube rotates to release the yarn, although the weft yarn tube will vibrate, through the cooperation of the connector 34 and the locking position 31, the position of the connector 34 is limited, and further the axial position of the connection between the connecting member and the first socket 2 is limited, greatly reducing the axial vibration of the first socket 2, improving the stability of the first socket 2, and further avoiding the axial movement of the first socket 2 when the weft yarn tube vibrates, which affects the stability of the weft yarn tube.

[0037] As Figure 3 shown, when the connector 34 is engaged with the unlocking position 32, the first socket 2 moves away from the second socket to facilitate the worker to disassemble or replace the weft yarn tube; As Figure 2 and Figure 3 shown, when it is necessary to disassemble the yarn tube, the connector 34 engaged with the locking position 31 is switched to be engaged with the unlocking position 32. By the cooperation of the connector 34 and the unlocking position 32, the first socket 2 is stabilized, avoiding the possibility that the first socket 2 moves back towards the second socket after moving axially away from the second socket while the weft yarn tube has not been completely disassembled and replaced. Compared with the existing shuttle, it avoids the spring pressing against the first socket 2 by the second socket, which affects the efficiency of the worker to disassemble the weft yarn tube and replace it with a new one, improves the stability after the weft yarn tube is installed, and at the same time, improves the stability of the first socket 2 during the disassembly and new installation of the weft yarn tube, thereby improving the efficiency of the disassembly and replacement of the weft yarn tube, shortening the downtime of the circular loom due to the replacement of the weft yarn tube, and overall improving the production efficiency of the circular loom.

[0038] In this embodiment, the locking position 31 is a locking groove, and the unlocking position 32 is an unlocking groove. When the connector 34 is engaged with the locking position 31 or the unlocking position 32, in essence, the connector 34 is inserted into the locking groove or the unlocking groove. By inserting into the locking groove or the unlocking groove, the stability of the connector 34 in the locking position 31 or the unlocking position 32 is improved, and the stability of the first socket 2 after axial fixation is improved. In another embodiment, the locking position 31 can be a locking rib, and the unlocking position 32 can be an unlocking rib. The connector 34 has a groove body for inserting with the locking rib or the unlocking rib. When the connector 34 is engaged with the locking position 31 or the unlocking position 32, it is actually the insertion of the groove body with the locking rib or the unlocking rib.

[0039] In this embodiment, as Figure 3 and Figure 4As shown, the connecting piece is provided with a guiding long hole 331. The plug-in piece 34 includes a plug-in part 341 which is slidably arranged in the guiding long hole 331. When the weft yarn tube is stably installed on the first tube seat 2 and the second tube seat, the plug-in part 341 cooperates with the locking position 31. When it is necessary to disassemble the weft yarn tube to replace it with a new one, the worker manually operates the plug-in part 341 to make the plug-in part 341 disengage from the locking position 31, and the plug-in part 341 is switched to cooperate with the unlocking position 32 as the connecting piece rotates. When the connecting piece rotates, it drives the first tube seat 2 away from the second tube seat, facilitating the disassembly of the weft yarn tube and the replacement of a new weft yarn tube.

[0040] In order to improve the sliding stability of the plug-in part 341 in the guiding long hole 331 and the plugging stability with the locking position 31 and the unlocking position 32, the plug-in part 341 includes a plugging end 3412 and a guiding end 3411. The outer shape of the plugging end 3412 is adapted to the shapes of the locking position 31 and the unlocking position 32. Specifically, in this embodiment, the locking position 31 is a locking groove, and the unlocking position 32 is an unlocking groove. The thickness of the plugging end 3412 gradually decreases along the plugging direction. More specifically, an inclined surface 3413 is provided on the side of the plugging end 3412 facing the second tube seat. The inclined surface 3413 inclines along the direction from the second tube seat towards the first tube seat 2 in the plugging direction of the plug-in part 341, so that the thickness of the plugging end 3412 gradually decreases along the plugging direction, ensuring that when the plugging end 3412 is plugged into the locking groove or the unlocking groove, the smaller end of the plugging end 3412 is plugged into the larger end of the locking groove or the unlocking groove first, ensuring that the plugging end 3412 can be plugged into the locking groove or the unlocking groove more accurately, improving the accuracy of plugging, reducing the precision required for the worker's operation, and thus reducing the operation difficulty of the worker.

[0041] The shapes of the locking groove and the unlocking groove in the distribution direction of the first tube seat 2 and the second tube seat are adapted to the outer shape of the plugging end 3412, so that after the plugging end 3412 is plugged into the locking groove or the unlocking groove, the outer wall of the plugging end 3412 fits with the groove wall of the locking groove or the unlocking groove, reducing the possibility of the plugging end 3412 shaking after plugging, improving the stability of the plugging end 3412 after plugging, and thus improving the stability of the first tube seat 2 on the mounting seat 3. The two side walls of the guiding end 3411 in the distribution direction of the first tube seat 2 and the second tube seat fit with the hole wall of the guiding long hole 331, ensuring that the guiding end 3411 can slide stably in the guiding long hole 331 and preventing the guiding end 3411 from deflecting in the guiding long hole 331 and affecting the plugging of the plugging end 3412 into the locking groove or the unlocking groove. The arrangement of the plugging end 3412 and the guiding end 3411 improves the stability of the plug-in part 341 after being plugged into the locking groove or the unlocking groove, and thus improves the stability of the first tube seat 2 after axial movement.

[0042] In another embodiment, such as Figure 4As shown, in order to further improve the stability of the connection part 341 with the locking position 31 and the unlocking position 32, a first elastic member 343 is provided between the connection part 341 and the connecting member, and the first elastic member 343 biases the connection part 341 toward the locking position 31 or the unlocking position 32 to maintain the connection; specifically, the first elastic member 343 is located on the side of the connection part 341 away from the locking position 31, and the first elastic member 343 is in a compressed state. The first elastic member 343 abuts the connection part 341 toward the locking position 31 or the unlocking position 32, thereby improving the stability of the connection part 341 with the locking position 31 or the unlocking position 32, and effectively preventing the connection part 341 from being separated from the locking position 31 or the unlocking position 32 and affecting the stability of the first tube seat 2 and the weft yarn tube.

[0043] In order to facilitate the worker to operate the plug part 341 to switch between the locking position 31 and the unlocking position 32, the connecting piece includes a mounting rod 33 and a connecting rod 21. The mounting rod 33 is hinged to the mounting seat 3. One end of the connecting rod 21 is connected to the first pipe seat 2, and the other end is hinged to the end of the mounting rod 33 away from the mounting seat 3. Figure 3 and Figure 4 As shown, the connector 34 also includes an operating portion 342, which is located on the side of the connector 341 away from the locking position 31, and one end of the operating portion 342 is connected to the connector 341, and the other end passes through the end surface of the mounting rod 33 away from the end of the mounting seat 3, and forms a gripping portion 3421 on the end surface of the mounting rod 33. When it is necessary to disassemble and replace the weft yarn tube, the worker holds the gripping portion 3421 and pulls the connector 341 in the direction away from the locking position 31, and drives the connector 341 in the guide slot 33 through the operating portion 342. 1, thereby driving the plug end 3412 of the plug portion 341 out of the locking position 31, and then rotating the mounting rod 33 in the direction away from the second tube seat. When the plug portion 341 is aligned with the unlocking position 32, the worker releases the grip 3421, and the plug portion 341, pushed by the first elastic member 343, engages with the unlocking position 32. During the rotation of the mounting rod 33, the connecting rod 21 drives the first tube seat 2 axially away from the second tube seat, ensuring that the first tube seat 2 no longer abuts the weft tube, allowing the worker to remove and replace the weft tube. The grip 3421 has a limiting step 3422. The limiting step 3422 abuts the end surface of the mounting rod 33 away from the mounting seat 3, preventing the operating portion 342 from entering the guide slot 331 under the action of the first elastic member 343, making it difficult for the worker to use the grip 3421 to drive the plug 34 along the guide slot 331 to disengage from the locking position 31 or the unlocking position 32.

[0044] In another embodiment, if Figure 3 and Figure 5As shown, the mounting base 3 includes a second base body 36 and a first base body 35 for mounting the first tube base 2. The second base body 36 includes a support 361 and a connecting plate 362 provided on the support 361. The support 361 is perpendicular to the axis direction of the first tube base 2 and perpendicular to the first base body 35. There are two connecting plates 362, and the two connecting plates 362 are distributed along the extending direction of the support 361. An accommodation space 363 for accommodating the connecting piece is formed between the two connecting plates 362. When the connecting piece is the mounting rod 33 and the connecting rod 21, one end of the mounting rod 33 is rotatably connected to the two connecting plates 362, and the other end extends out of the accommodation space 363. The accommodation space 363 extends in the rotation direction of the mounting rod 33 to avoid the rotation of the mounting rod 33; more specifically, the two connecting plates 362 are in mutual contact with the two side walls of the mounting rod 33; to prevent the mounting rod 33 from shifting or shaking towards the connecting plate 362 during rotation, and improve the stability of the mounting rod 33; as Figure 4 and Figure 5 As shown, locking positions 31 and unlocking positions 32 are provided on both of the two connecting plates 362, and the insertion part 341 cooperates with the two locking positions 31 or the two unlocking positions 32 at the same time; it can be understood that in this embodiment, the insertion part 341 protrudes from the two side walls of the mounting rod 33 in the distribution direction of the two connecting plates 362, and both ends of the insertion part 341 cooperate with the corresponding two locking positions 31 or the two unlocking positions 32, increasing the contact area between the insertion part 341 and the locking position 31 or the unlocking position 32, and further improving the stability of the insertion part 341.

[0045] In order to ensure the stability of the accommodation space 363, as Figure 5 As shown, a sleeve 364 for forming the accommodation space 363 between the two connecting plates 362 is provided between the two connecting plates 362. Specifically, the two connecting plates 362 abut against both ends of the sleeve 364, so that an accommodation space 363 for accommodating the connecting piece is formed between the two connecting plates 362. By abutting the two connecting plates 362 against both ends of the sleeve 364, the stability of the accommodation space 363 is improved, and effectively preventing the accommodation space 363 from shaking during the circumferential movement of the shuttle frame 1 and affecting the stability of the connecting piece.

[0046] In another embodiment, fixing rods 3621 are provided on the two connecting plates 362 below the locking positions 31. The strength of the two connecting plates 362 is improved by the fixing rods 3621, effectively preventing the two connecting plates 362 from shaking during the circumferential movement of the shuttle frame 1; the connecting piece is rotatably connected to the fixing rod 3621, ensuring that the connecting piece is located in the accommodation space 363, and the connecting piece can rotate relatively smoothly relative to the connecting plate 362 to drive the first tube base 2 to axially move, reducing the difficulty for workers to replace the weft tube.

[0047] In order to facilitate the axial sliding of the first tube base 2, as Figure 3 and Figure 5As shown, a guide shaft 351 is provided at the top of the first base body 35. The guide shaft 351 extends towards the second socket. The first socket 2 is slidably sleeved on the guide shaft 351. A second elastic member 352 is provided between the first socket 2 and the first base body 35. The second elastic member 352 biases the first socket 2 towards the second socket; specifically, the second elastic member 352 is in a compressed state between the first base body 35 and the first socket 2, and the second elastic member 352 abuts against the first socket 2 towards the second socket, so that the first socket 2 has a tendency to move towards the second socket to axially fix the weft tube; during the process of switching the plug-in member 34 from the unlocking position 32 to cooperate with the locking position 31, the second elastic member 352 pushes the first socket 2 towards the second socket to ensure that the first socket 2 can axially move and fix the weft tube.

[0048] In this embodiment, as Figure 3 shown, in order to prevent the first socket 2 from axially disengaging from the guide shaft 351, a blocking member 353 is provided at the end of the guide shaft 351 away from the first base body 35. The blocking member 353 axially blocks the first socket 2; through the blocking of the blocking member 353, the first socket 2 is prevented from disengaging from the guide shaft 351.

[0049] In another embodiment, the second base body 36 has a positioning plate located between the mounting rod 33 and the first base body 35. Both the locking position 31 and the unlocking position 32 are located on the positioning plate. The locking position 31 is a locking hole, and the unlocking position 32 is an unlocking hole. The axes of the locking hole and the unlocking hole are parallel to the rotation axis of the mounting rod 33. A plug-in rod is slidably mounted on the mounting rod 33. When the plug-in rod is aligned with the locking hole, the worker drives the plug-in rod to slide relative to the mounting rod 33 to insert it into or disengage from the locking hole. After the plug-in rod disengages from the locking hole and the mounting rod 33 is rotated to align the plug-in rod with the unlocking hole, the worker drives the plug-in rod to slide relative to the mounting rod 33 to insert it into the unlocking hole.

[0050] In another embodiment, the present invention further provides a circular loom, which includes a door ring assembly and a shuttle. The shuttle moves in a circular motion on the door ring assembly. When the shuttle moves in a circular motion, the yarn on the weft yarn tube is released to assist the weaving of the circular loom. The shuttle is the shuttle for the circular loom in the above embodiment. When the shuttle for the circular loom is applied to the circular loom, when the first tube seat 2 and the second tube seat axially fix the weft yarn tube, the cooperation between the plug-in member 34 and the locking position 31 is used to improve the stability of the first tube seat 2, effectively avoiding the shaking of the weft yarn tube during the process of releasing the yarn, which affects the stability of the first tube seat 2 and further affects the stability of the weft yarn tube. When it is necessary to disassemble and replace the weft yarn tube, the plug-in member 34 inserted in the locking position 31 is switched to the unlocking position 32. During the switching process, the rotation of the connecting member drives the first tube seat 2 away from the second tube seat, thereby facilitating the disassembly and replacement of the weft yarn tube. The cooperation between the plug-in member 34 and the unlocking position 32 improves the stability of the first tube seat 2 during the disassembly process, avoiding the reset of the first tube seat 2 and affecting the disassembly and replacement of the weft yarn tube by the worker. It improves the replacement efficiency of the weft yarn tube, shortens the downtime of the circular loom, and thus improves the production efficiency of the circular loom as a whole.

[0051] In addition to the above preferred embodiments, the present invention has other implementation manners. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope claimed by the present invention.
