[0002] The large circular machine, scientifically known as the knitting circular weft knitting machine, has multiple loop forming systems, high speed, high output, fast pattern change, good fabric quality, fewer processes and strong product adaptability. The large circular machine is composed of a frame, a yarn feeding mechanism, a transmission mechanism, a cleaning mechanism, a control mechanism, a pulling and curling mechanism and an auxiliary mechanism.

[0003] When changing the wire of the existing large circular knitting machine, the staff are mostly required to manually lift the coil and connect the wires. Since the coil itself is heavy, the staff needs to lift the coil to a higher yarn frame. The long-term work consumes a lot of physical energy of the staff. In addition, the yarn will inevitably be a little loose when it is connected, which affects the quality of the finished product. The yarn itself also has a little floating dust, which cannot be removed all by blowing with a fan alone.

[0004] Therefore, a yarn feeding structure of a circular knitting machine is proposed. Utility Model Content

[0027] like Figures 1 to 4 As shown, a specific embodiment of the utility model provides a yarn feeding structure of a large circular knitting machine, comprising a main body 1, a support block 2 is arranged on the outside of the main body 1, a motor 3 is arranged above the support block 2, and a yarn feeder 6 is arranged above the motor 3;

[0028] A lifting mechanism, the lifting mechanism comprises a support platform 4 arranged inside the motor 3, and a lifting platform 5 is arranged on the upper end of the support platform 4;

[0029] The wire feeding mechanism comprises a yarn wheel 7 arranged above the wire feeder 6, a yarn outlet platform 17 is arranged at the lower end of the wire feeder 6, and two groups of automatic telescopic columns 21 are arranged on both sides of the lower end of the wire feeder 6.

[0030] By adopting the above technical scheme, the utility model is designed with a lifting mechanism and a wire feeding mechanism. The lifting mechanism can make the yarn frame 15 perform lifting and lowering movements, which is convenient for the staff to remove the used yarn wheel 7 and put on a new yarn wheel 7, reducing the work intensity of the staff. The wire feeding mechanism can adjust the tightness of the line, which is convenient for tightening the loose yarn and slightly loosening the tight yarn.

[0031] Specifically, Figure 1 and Figure 2 As shown, the support block 2 and the support platform 4 are provided with an inner groove 8, the lower end of the lifting platform 5 is provided with a limit block 9, the size of the limit block 9 is adapted to the lifting platform 5, the upper end of the motor 3 is fixedly connected with a storage platform 10, the output shaft of the motor 3 passes through the storage platform 10 and is fixedly connected with a screw rod 11, the outer side of the upper end of the screw rod 11 is sleeved on the lifting block 13, the upper end of the lifting block 13 is connected with a fixed block 14, two groups of sliding shafts 12 are fixedly connected on both sides of the upper end of the storage platform 10, the two groups of sliding shafts 12 pass through the lifting block 13 and are slidably connected, and the upper ends of the two groups of sliding shafts 12 are fixedly connected with the fixed block 14.

[0032] By adopting the above technical scheme, when working, the motor 3 is started, and the motor 3 drives the screw rod 11 to rotate. Because the lifting block 13 is rotationally connected to the screw rod 11, the sliding shaft 12 is slidingly connected to the lifting block 13, and the sliding shaft 12 is fixedly connected to the fixed block 14, the screw rod 11 drives the lifting block 13 to move up and down. Because the lifting block 13 is fixedly connected to the lifting platform 5 and the yarn rack 15, the lifting block 13 drives the yarn rack 15 to move up and down. Finally, because the limit block 9 is adapted to the size of the lifting platform 5, the lifting range of the lifting block 13 is limited, which is conducive to the placement of the yarn wheel 7 on the yarn rack 15, and it is convenient for the staff to remove the used yarn wheel 7 and put on the new yarn wheel 7, thereby reducing the work intensity of the staff. In addition, the design of the multi-layer yarn rack 15 reduces the number of times the yarn wheel 7 needs to be lifted for replacement, thereby reducing the time cost of production.

[0033] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the interior of the wire feeder 6 is provided with a wire inlet 16 and a brush 18, a first opening 19 is provided below the wire inlet 16, a second opening 20 is provided on the lower right side of the wire inlet 16, two groups of telescopic blocks 22 are fixedly connected to the lower ends of the two groups of automatic telescopic columns 21, a winding shaft 23 is fixedly connected in the middle of the two groups of telescopic blocks 22, the right end of the wire feeder 6 is snap-connected with a cover plate 24, and the front and rear ends of the cover plate 24 are fixedly connected with an opening plate 25.

[0034] By adopting the above technical solution, the yarn is connected from the yarn wheel 7 to the feeder 6, the cover 24 is opened to connect the yarn to the lower end of the wire inlet 16, and then the yarn passes around the winding shaft 23 through the first opening 19 and is connected from the second opening 20. When the machine is started, the brush 18 cleans the yarn as the yarn passes along the above channel. When the tightness of the yarn needs to be adjusted, the automatic telescopic column 21 is started to drive the telescopic block 22 to retract and adjust the yarn to the most suitable tightness, which is conducive to further cleaning of the yarn and is convenient for tightening the loose yarn and slightly loosening the tight yarn. After the cover 24 is opened, the accumulated dust can be cleaned, and the accumulated dust will not be blown into the air to affect the respiratory tract of the staff.

[0035] Working principle: When working, start the motor 3, and the motor 3 drives the screw rod 11 to rotate. Because the lifting block 13 is rotatably connected with the screw rod 11, the sliding shaft 12 is slidably connected with the lifting block 13, and the sliding shaft 12 is fixedly connected with the fixed block 14, the screw rod 11 drives the lifting block 13 to move up and down. Because the lifting block 13 is fixedly connected with the lifting platform 5 and the yarn frame 15, the lifting block 13 drives the yarn frame 15 to move up and down. Finally, because the limit block 9 is adapted to the size of the lifting platform 5, the lifting range of the lifting block 13 is limited, which is conducive to the placement of the yarn wheel 7 on the yarn frame 15, and it is convenient for the staff to remove the used yarn wheel 7 and put a new yarn wheel 7, which reduces the work intensity of the staff. In addition, the design of the multi-layer yarn frame 15 reduces the number of times the yarn wheel 7 needs to be lifted for replacement, thereby reducing the time cost of production.

[0036] The yarn is fed into the feeder 6 from the yarn wheel 7, and the cover 24 is opened to connect the yarn to the lower end of the wire inlet 16. The yarn then passes around the winding shaft 23 through the first opening 19 and is then taken out from the second opening 20. When the machine is started, the brush 18 cleans the yarn as the yarn passes along the above-mentioned channel. When the tightness of the yarn needs to be adjusted, the automatic telescopic column 21 is started to drive the telescopic block 22 to telescope online. Adjusting the yarn to the most suitable tightness is conducive to further cleaning of the yarn, and is convenient for tightening the loose yarn and slightly loosening the tight yarn. After the cover 24 is opened, the accumulated dust can be cleaned, and the accumulated dust will not be blown into the air to affect the respiratory tract of the staff.
