DETAILED DESCRIPTION
[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0032] In order to prevent the problem of uneven quality of woven products caused by unstable yarn tension, to prevent the problem of dust and impurities on the yarn affecting the appearance and quality of the product, and to prevent the problem of poor adaptability of the existing yarn feeding device due to difficulty in flexible adjustment according to different yarn materials and weaving requirements, the stability of product quality, product appearance quality and adaptability of the yarn feeding device are improved. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The top of described sliding panel also has the fixed position that is provided with guide rail, and the bottom of described sliding panel is provided with guide rail, and the bottom of described sliding panel is provided with guide rail.
[0033] A square box 12 is fixedly installed on the top of each of the cross bars 7 away from the slides 9. A first servo motor 13 is fixedly installed on the edge of one end of the square box 12. The inner walls of both ends of the square box 12 are rotatably connected to a worm 14. The output shaft of the first servo motor 13 passes through the square box 12 and is fixedly connected to one end of the worm 14. A slide 15 is rotatably connected to the inner wall of the bottom end of the square box 12, and a worm gear 16 is fixedly connected to the outer upper part of the slide 15. The worm gear 16 is engaged with the worm 14.
[0034] The bottom end of the slide 15 extends to the outside through the square box 12, and a threaded rod 17 is threadedly connected to the lower part of the slide 15. The bottom end of the threaded rod 17 is fixedly connected to the slide 9, and the top inner wall of the slide 9 is fixedly connected to the support plate 18. A slide 19 is slidably connected to the inside of the slide 9 and directly below the support plate 18. Several springs 20 arranged at equal distances are connected between the slide 19 and the support plate 18. The inner walls at both ends of the slide 19 are rotatably connected to the second tension roller 21 and the second cleaning roller 22.
[0035] During use, according to the material of the yarn and the weaving requirements, the height of the crossbar 7 is adjusted by driving the motor 4 so that the yarn is in a suitable position between the first tension roller 11 and the first cleaning roller 31 in the through groove 8. The first servo motor 13 is started to adjust the height of the slide 9 so that the yarn is also in a suitable tension state between the second tension roller 21 and the second cleaning roller 22 in the slide 9.
[0036] The yarn passes through the first cleaning roller 31 and the second cleaning roller 22 in the through slot 8, and then through the first tension roller 11 and the second tension roller 21. During the yarn feeding process, if the yarn tension changes, the carriage 19 will move up and down under the action of the spring 20, automatically adjusting the yarn tension to ensure that the yarn always remains within the appropriate tension range. At the same time, the first cleaning roller 31 and the second cleaning roller 22 clean the yarn, removing impurities and dust from the yarn.
[0037] According to the actual situation during the weaving process, the heights of the crossbar 7 and the slide 9 can be adjusted at any time by the drive motor 4 and the first servo motor 13 to adapt to different yarn tension requirements and weaving conditions.
[0038] For example, Figure 1 As shown, the present invention further includes that the end of the support 1 away from the first side plate 3 is fixedly connected to the second side plate 23 , and the top end and the bottom end inner wall of the second side plate 23 are fixedly connected to a sliding rod 24 .
[0039] When in use, the arrangement of the slide bar 24 provides stable support and guidance for subsequent structures or operations, ensuring that relevant components can maintain accurate positions and motion trajectories during operation.
[0040] For example, Figure 1 As shown, the present invention further includes that a slider 25 is sleeved on the outside of the slide rod 24 , and one end of the slider 25 is fixedly connected to one end of the cross bar 7 .
[0041] When in use, the cross bar 7 is made more stable during movement. The cooperation of the slide bar 24 and the slider 25 provides additional support and guidance for the cross bar 7, ensuring that the cross bar 7 can slide smoothly in a predetermined direction, thereby ensuring the accuracy and reliability of the entire yarn feeding device during operation.
[0042] For example, Figure 1 As shown, the present invention also includes that the bracket 2 is provided with two groups, and the two groups of the brackets 2 are respectively located on both sides of the support 1, and the upper part of the inner wall at both ends of one group of the brackets 2 is rotatably connected to the yarn drum 26.
[0043] When in use, the yarn drum 26 can rotate freely on the bracket 2, providing a source of yarn for the yarn feeding process. When the yarn feeding device is working, the yarn on the yarn drum 26 is gradually drawn out, and the tension is adjusted and transported through subsequent components to ensure that the yarn can enter the weaving area of the computer flat knitting machine with appropriate tension and speed.
[0044] For example, Figure 1 As shown, the present invention also includes another group of the upper inner walls at both ends of the bracket 2, which are rotatably connected to a first yarn guide wheel 27 and a yarn feeding wheel 28, and the inner walls at both ends of the bracket 2 are rotatably connected to a second yarn guide wheel 29 directly below the yarn feeding wheel 28.
[0045] When in use, the first yarn guide wheel 27, the yarn feeding wheel 28 and the second yarn guide wheel 29 cooperate with each other to guide the direction of the yarn and assist in conveying the yarn during the yarn feeding process. After the yarn is drawn out from the yarn drum 26, it first changes direction through the first yarn guide wheel 27, and then is powered by the yarn feeding wheel 28 for conveying. Finally, it passes through the second yarn guide wheel 29 to further adjust the direction and enter the through slot 8 on the support 1 for subsequent tension adjustment and cleaning.
[0046] For example, Figure 1 As shown, the present invention also includes a second servo motor 30 fixedly mounted on an outer wall of one side of the bracket 2 close to the yarn feeding wheel 28 , and an output shaft of the second servo motor 30 passes through the bracket 2 and is fixedly connected to one end of the yarn feeding wheel 28 .
[0047] When in use, the second servo motor 30 provides power to the yarn feeding wheel 28, enabling it to rotate at a specific speed, thereby achieving stable delivery of the yarn. By controlling the rotation speed of the second servo motor 30, the yarn feeding speed can be adjusted to meet different weaving requirements.
[0048] It should be noted that the utility model is a yarn feeding device for a computerized flat knitting machine. According to the material of the yarn and the weaving requirements, the driving motor 4 is started, and the driving motor 4 drives the screw rod 5 to rotate. The sleeve block 6 on the screw rod 5 drives the cross bar 7 to move up and down, and the height of the cross bar 7 is adjusted so that the yarn is in a suitable position between the first tension roller 11 and the first cleaning roller 31 in the through groove 8; the first servo motor 13 is started, and the first servo motor 13 drives the worm 14 to rotate. The worm 14 engages with the worm gear 16 to drive the slide 15 to rotate, and the threaded rod 17 in the slide 15 drives the slide 9 to move up and down, and the height of the slide 9 is adjusted so that the yarn is in a suitable tension state between the second tension roller 21 and the second cleaning roller 22 in the slide 9; according to the weaving requirements, the rotation speed of the yarn feeding wheel 28 is adjusted by controlling the rotation speed of the second servo motor 30, thereby adjusting the yarn feeding speed;
[0049] The yarn is drawn out from the bobbin 26, changes direction after passing through the first yarn guide wheel 27, and is transported by the yarn feed wheel 28 driven by the second servo motor 30. After passing through the yarn feed wheel 28, the yarn is further adjusted in direction by the second yarn guide wheel 29. The yarn enters the through slot 8 on the support 1, passes through the first cleaning roller 31 and the second cleaning roller 22 in the through slot 8 in turn to be cleaned to remove impurities and dust on the yarn, and then passes through the first tension roller 11 and the second tension roller 21;
[0050] During the yarn feeding process, the yarn tension is monitored in real time. When the yarn tension changes, the slide 19 will move up and down under the action of the spring 20, automatically adjusting the yarn tension to ensure that the yarn always remains within the appropriate tension range. According to the actual situation during the weaving process, the height of the cross bar 7 and the slide 9 can be adjusted at any time by driving the motor 4 and the first servo motor 13 to adapt to different yarn tension requirements; the yarn feeding speed is adjusted by controlling the speed of the second servo motor 30 to meet different weaving conditions.
