The weft knitting circular machine is a kind of textile machinery, and its main components include a machine frame, a cam plate, a spinning wheel, a gear, a threaded guide rod and a raw material drum. Its working principle is to use the friction force between the spinning wheel and the cam plate to wind the raw material on the cam plate, and then guide the thread into the hook through the threaded guide rod, and finally form the finished fabric.

[0003] In the process of weft knitting circular machine processing, a hanging rack is needed to provide knitting thread. The hanging rack is also called a yarn guide.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0032] Please see Figures 1-11 A yarn bobbin hanger structure for a weft knitting circular knitting machine includes a horizontal frame 1, a vertical frame 7, and rollers 8. A fixed frame 3 is provided at equal intervals below the horizontal frame 1. A hook 4003 is provided on one side of the fixed frame 3. The yarn bobbin 5 is sleeved on the outer circumference of the hook 4003. A locking component 4 is provided inside the fixed frame 3. A snap-fit ​​component 9 is provided on one side of the locking component 4. A prompting component 6 for alerting yarn breakage is provided on one side of the snap-fit ​​component 9. The prompting component 6 is fixedly connected to the snap-fit ​​component 9. The prompting component 6 includes a first fixed plate 6001. A reinforcing column 6004 is fixedly connected to one outer wall of the first fixed plate 6001. A second fixed plate 6003 is fixedly connected to the end of the reinforcing column 6004 away from the first fixed plate 6001. A rotating shaft 6005 is rotatably connected to one side of both the first fixed plate 6001 and the second fixed plate 6003. A guide wheel 6002 is fixedly connected to the outer circumference of the rotating shaft 6005. While the yarn bobbin 5 is conveying the yarn, the guide wheel 6002 can provide good guidance for the yarn, avoiding problems such as yarn tangling and uneven yarn guidance during the transmission process. A limiting piece 6007 is provided on one side of the guide wheel 6002. There are two sets of limiting pieces 6007, and both sets of limiting pieces 6007 are fixedly connected to the outer circumference of the rotating shaft 6005. A sleeve is fitted on the outer circumference of the rotating shaft 6005. The sleeve 6006 has both ends in contact with the outer wall of the limiting piece 6007. A warning plate 6008 is fixedly connected to the outer circumference of the sleeve 6006. During the transmission of yarn by the guide wheel 6002, the rotating shaft 6005 will rotate together. When the rotating shaft 6005 rotates, it can drive the sleeve 6006, which is sleeved on its outer wall, to rotate together. At the same time, the rotation of the sleeve 6006 can also drive the warning plate 6008 to make a circular motion. When the yarn breaks, the guide wheel 6002 can no longer transmit yarn, so the rotating shaft 6005 will also stop rotating. When the rotating shaft 6005 stops rotating, the warning plate 6008 will be in a vertical downward position due to gravity and will remain in a different position. This makes it easy for workers to quickly find the broken yarn, thus providing a good warning effect while guiding the yarn. Both sides of the vertical frame 7 are provided with positioning components 2 for fixing the fixed frame 3.

[0033] Preferably, the positioning component 2 includes a sliding post 2006 fixedly connected to one end of the fixed frame 3. A circular plate 2002 is fixedly connected to one end of the sliding post 2006. A first spring 2003 is fixedly connected to one outer wall of the circular plate 2002. A positioning ring plate 2004 is fixedly connected to the end of the first spring 2003 away from the circular plate 2002. The positioning ring plate 2004 abuts against one outer wall of the vertical frame 7. A handle 2005 is fixedly connected to the circumferential outer wall of the positioning ring plate 2004. A circularly spaced handle is inserted into one side of the circular plate 2002. The guide posts 2007 are distributed, and one end of the guide post 2007 is fixedly connected to the outer wall of the positioning ring plate 2004. A sliding groove 2001 is opened on one outer wall of the vertical frame 7. One end of the sliding post 2006 passes through the inside of the sliding groove 2001. The outer circumference of the sliding post 2006 contacts the inner walls on both sides of the sliding groove 2001, which makes it convenient for the staff to adjust the vertical height of the fixed frame 3. After the adjustment is completed, the fixed frame 3 can be locked and fixed by the first spring 2003 in conjunction with the positioning ring plate 2004.

[0034] Preferably, the locking assembly 4 includes a housing 4001 disposed inside the fixing frame 3. Pressure plates 4005 are provided on both the upper and lower outer walls of the housing 4001. A second spring 4006 is fixedly connected to one outer wall of the pressure plate 4005. The end of the second spring 4006 away from the pressure plate 4005 is fixedly connected to one outer wall of the housing 4001. The pressure plate 4005 is pressed against the inner wall of the fixing frame 3 by the second spring 4006. A U-shaped rod 4008 is fixedly connected to the bottom of the pressure plate 4005 located above the housing 4001. Both ends of the U-shaped rod 4008 away from the pressure plate 4005 extend from the top of the housing 4001. The U-shaped rod 4008 has two ends fixedly connected to pressing rods 4007. A movable rod 4002 is fixedly connected to the outer wall of one side of the pressure plate 4005 located below the housing 4001. A rotating seat 4009 is fixedly connected to the top of the movable rod 4002. A connecting rod 4011 is rotatably connected to the rotating seat 4009. A support seat 4010 is fixedly connected to the inner wall of the bottom of the housing 4001. The connecting rod 4011 is rotatably connected to the support seat 4010. A docking seat 4013 is fixedly connected to the end of the connecting rod 4011 away from the rotating seat 4009. A pressing column 4012 is fixedly connected to the outer circumference of the U-shaped rod 4008. One end of column 4012 is located inside docking seat 4013. When the operator needs to adjust the yarn transmission position to meet the knitting requirements of the weft knitting circular knitting machine, the operator first presses the pressing rod 4007 to apply downward pressure to the U-shaped rod 4008. When the U-shaped rod 4008 is subjected to downward pressure, it will cause the pressure plate 4005 to drop as a whole. At the same time, the pressing column 4012 below the U-shaped rod 4008 will also apply downward pressure to the docking seat 4013, thereby causing the other end of the connecting rod 4011 to tilt up. When the other end of the connecting rod 4011 tilts up, it can drive the movable rod 4002 to rise together, thereby enabling the adjustment of the yarn transmission position of the weft knitting circular knitting machine. The pressure plate 4005 below the housing 4001 also moves towards the side closer to the housing 4001, thereby effectively releasing the clamping limit of the two sets of pressure plates 4005, allowing the housing 4001 to move within the fixed frame 3, satisfying people's needs for adjusting the position of the housing 4001. After the position of the housing 4001 is adjusted, the operator releases the pressure plate 4005. At this time, the second spring 4006, which is in a compressed state, will once again drive the pressure plate 4005 to press against the inner wall of the fixed frame 3, thereby completing the locking and fixing of the housing 4001 and ensuring the stability of the housing 4001 inside the fixed frame 3.

[0035] Preferably, a side plate 4004 is fixedly connected to one outer wall of the housing 4001. The upper and lower outer walls of the side plate 4004 are in contact with the upper and lower inner walls of the fixing frame 3, which can provide a certain support for the installation of the housing 4001.

[0036] Preferably, the snap-fit ​​assembly 9 includes a second fixing post 9016 and a fixing tube 9001 fixedly connected to the inner wall of one side of the housing 4001. A first fixing post 9015 is fixedly connected to one end of the second fixing post 9016. The inner diameter of the first fixing post 9015 is smaller than the inner diameter of the second fixing post 9016. A first trapezoidal block 9003 is fixedly connected to one end of the first fixing post 9015. A second trapezoidal block 9013 and a third trapezoidal block 9014 are slidably connected to the outer circumferential wall of the first fixing post 9015. A mating groove 9004 is provided at one end of the first trapezoidal block 9003, which is adapted to the second trapezoidal block 9013. A second circular groove 9006 and a movable groove 9010 are provided on the inner circumferential wall of the fixing tube 9001. The groove 9006 is connected to the movable groove 9010. A movable column 9007 is inserted into the inside of the second circular groove 9006. A fourth spring 9012 is fixedly connected to the inner wall of one side of the second circular groove 9006. A stop block 9011 is fixedly connected to the end of the fourth spring 9012 away from the second circular groove 9006. The cross-section of the stop block 9011 is a right trapezoid. A through groove 9018 is opened on one side of the housing 4001. One end of the fixed tube 9001 passes through the inside of the through groove 9018. A mounting plate 9017 is fixedly connected to one end of the fixed tube 9001. The mounting plate 9017 is fixedly connected to the first fixed plate 6001. When the operator replaces the hooks 4003 with different inclination angles or thicknesses to meet the feeding requirements of the weft knitting circular knitting machine... The operator can press the fixing tube 9001 to move it into the housing 4001. When the stop block 9011 contacts the second trapezoidal block 9013 and the third trapezoidal block 9014, it can open the stop block 9011 and compress the fourth spring 9012. At this time, the stop block 9011 will be clamped on the outer circumference of the third trapezoidal block 9014 due to the action of the fourth spring 9012. Then the operator pulls out the fixing tube 9001. During the process of pulling out the fixing tube 9001, the stop block 9011 can drive the second trapezoidal block 9013 and the third trapezoidal block 9014 to move together until the second trapezoidal block 9013 is engaged in the mating groove 9004. At this time, one end of the first trapezoidal block 9003 and the third trapezoidal block 9004 are engaged in the mating groove 9004. When one end of the first trapezoidal block 9014 is engaged, and the third trapezoidal block 9014 cannot move further, the stop block 9011 will slide along the outer wall of the first trapezoidal block 9003. At this time, by continuing to pull the fixing tube 9001, it can be quickly pulled out from inside the housing 4001, completing the quick disassembly of the hook 4003. This makes it convenient for people to better handle hooks 4003 of different inclinations or specifications. When replacing a new hook 4003, it is only necessary to insert the fixing tube 9001 into the housing 4001 again. The fixing tube 9001 will drive the stop block 9011 to move together until the stop block 9011 moves to the end of the first trapezoidal block 9003 where the mating groove 9004 is opened. At this time, the first trapezoidal block 9003 can play a good limiting role for the stop block 9011.This design prevents the fixing tube 9001 from detaching from the housing 4001 and falling out, thus facilitating the installation of the hook 4003.

[0037] Preferably, a first circular groove 9002 is formed on one side of the inner wall of the mating groove 9004. A third spring 9005 is fixedly connected to one side of the inner wall of the first circular groove 9002. One end of the third spring 9005 extends to the outside of the first circular groove 9002. When the stop block 9011 is separated from the third trapezoidal block 9014, the third spring 9005 can apply elastic force to the second trapezoidal block 9013 and the third trapezoidal block 9014, separating the second trapezoidal block 9013 and the third trapezoidal block 9014 from the first trapezoidal block 9003, which facilitates the subsequent installation of the hook 4003.

[0038] Preferably, a horizontal plate 9008 is fixedly connected to the outer circumference of the U-shaped rod 4008, and a ring block 9009 is fixedly connected to one end of the fixing tube 9001. The outer circumference of the ring block 9009 abuts against the bottom outer wall of the horizontal plate 9008. During the insertion of the fixing tube 9001, the ring block 9009 can apply an upward squeezing force to the horizontal plate 9008, which further improves the locking effect of the locking assembly 4. This allows the snap-fit ​​assembly 9 to achieve a locking and strengthening effect on the housing 4001 while ensuring the stable installation of the hook 4003.

[0039] In summary, with the aid of the above-mentioned technical solution of the present invention, during use, the operator passes the yarn spool 5 through one end of the hook 4003, and simultaneously connects the yarn wound around the outside of the yarn spool 5 to the weft knitting circular knitting machine, completing the material conveying to the weft knitting circular knitting machine. While the yarn spool 5 conveys the yarn, the guide wheel 6002 provides good guidance for the yarn, preventing problems such as yarn tangling and uneven yarn guidance during transmission. Furthermore, during the transmission of the yarn by the guide wheel 6002, the rotating shaft 6005 rotates together. When the rotating shaft 6005 rotates, it drives the sleeve 6006 fitted onto its outer wall to rotate together. Simultaneously, the rotation of the sleeve 6006 also drives the indicator plate 6008 to perform circular motion. When a yarn breaks, the guide wheel 6002 can no longer transmit power to the yarn, causing the rotating shaft 6005 to stop rotating. When the rotating shaft 6005 stops rotating, the indicator plate 6008 will remain vertically downward due to gravity, allowing workers to quickly locate the broken yarn. This provides a good indication while guiding the yarn. When workers need to adjust the yarn transmission position to meet the requirements of weft knitting circular knitting machines, they first press the pressing lever 4007 to apply downward pressure to the U-shaped rod 4008. When the U-shaped rod 4008 is subjected to downward pressure, it will cause the pressure plate 4005 to descend. At the same time, the pressure column 4012 below the U-shaped rod 4008 will also engage with the docking seat 401. 3. Applying downward pressure causes the other end of connecting rod 4011 to tilt upwards. When the other end of connecting rod 4011 tilts upwards, it drives movable rod 4002 to rise as well. This causes pressure plate 4005, located below housing 4001, to move closer to housing 4001, effectively releasing the clamping limit of the two sets of pressure plates 4005. This allows housing 4001 to move within fixed frame 3, satisfying the need for position adjustment of housing 4001. After the position of housing 4001 is adjusted, the operator releases pressure plate 4005. At this time, the compressed second spring 4006 will again drive pressure plate 4005 to press against the inner wall of fixed frame 3, thus completing the locking and fixing of housing 4001. This ensures the stability of the housing 4001 within the fixed frame 3. When operators need to replace hooks 4003 with different inclination angles or thicknesses to meet the feeding requirements of the weft knitting circular knitting machine, they can press the fixed tube 9001 to move it inwards from the housing 4001. When the stop block 9011 contacts the second trapezoidal block 9013 and the third trapezoidal block 9014, it can open the stop block 9011 (moving it closer to the inner wall of the fixed tube 9001) and compress the fourth spring 9012. At this time, the stop block 9011 will be clamped onto the outer circumference of the third trapezoidal block 9014 due to the action of the fourth spring 9012. Subsequently, the operator can pull out the fixed tube 9001. During the process of pulling out the fixed tube 9001...The stop block 9011 can move the second trapezoidal block 9013 and the third trapezoidal block 9014 together until the second trapezoidal block 9013 is engaged in the mating groove 9004. At this time, one end of the first trapezoidal block 9003 is in contact with one end of the third trapezoidal block 9014, and the third trapezoidal block 9014 can no longer move. The stop block 9011 will slide along the outer wall of the first trapezoidal block 9003. At this time, continuing to pull the fixing tube 9001 can quickly pull it out from the inside of the housing 4001, completing the quick disassembly of the hook 4003. This makes it convenient for people to better handle hooks 4003 of different inclinations or specifications. When replacing a new hook 4003, it is only necessary to insert the fixing tube into the inside of the housing 4001 again. 9001, the fixing tube 9001 moves together with the stop block 9011 until the stop block 9011 moves to the end of the first trapezoidal block 9003 where the mating groove 9004 is opened. At this time, the first trapezoidal block 9003 can effectively limit the stop block 9011, preventing the fixing tube 9001 from detaching and falling out of the housing 4001, thus facilitating the installation of the hook 4003. At the same time, during the insertion of the fixing tube 9001, the ring block 9009 can apply an upward compressive force to the horizontal plate 9008, further improving the locking effect of the locking assembly 4. This allows the snap-fit ​​assembly 9 to achieve a locking and strengthening effect on the housing 4001 while ensuring the stable installation of the hook 4003.
