Description
Technical Field
[0001] This utility model relates to the field of knitting machine needle technology, and in particular to a needle adjustment component for a sweater knitting machine. Background Technology
[0002] When adjusting the stitches on a knitting machine, a stitch adjustment component is often used. This device adjusts the stitch density and length during the knitting process, allowing for flexible changes in stitch size to meet different design requirements. This enables the knitting of sweaters with various styles and functions, satisfying diverse market demands. Using this component improves production efficiency, reduces defect rates caused by inconsistent stitches, and allows designers to realize more complex and intricate patterns and structures.
[0003] The stitch adjustment component of a wool sweater knitting machine mainly involves fine-tuning the stitches of the knitting machine to ensure the knitting quality and effect of the wool sweater. This typically includes checking the current stitch settings, selecting the appropriate stitch specifications according to the knitting requirements, adjusting the stitch position and density, testing the knitting effect, and making necessary fine adjustments until the expected knitting quality standard is achieved.
[0004] In existing technologies, some devices, such as the traditional needle adjustment components of wool sweater knitting machines, have significant technical defects. On the one hand, existing devices struggle to precisely adjust the needle depth. When knitting wool sweaters of different thicknesses and textures, the needle depth directly affects the fabric's density and smoothness. However, existing technologies cannot finely adjust the needle depth according to actual needs, resulting in inconsistent quality of the knitted sweaters. On the other hand, when dealing with complex and varied knitting processes, existing needle adjustment components lack flexibility and cannot change the needle depth promptly and accurately, limiting the diversity of wool sweater designs and hindering the development of innovative designs in the wool sweater industry. Therefore, this paper proposes a needle adjustment component for wool sweater knitting machines to address these issues. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1 to 2 This utility model provides an embodiment of a sweater knitting machine needle adjustment assembly, including a base plate 1, which serves to support and fix the machine, providing a stable mounting base for the bracket 2 and the machine housing 3, ensuring that the entire needle adjustment assembly remains stable during operation, and avoiding the impact on knitting quality and precision due to shaking or displacement. The bracket 2 is fixedly connected to the top side of the base plate 1, serving as a support frame for the adjustment mechanism and tension mechanism, fixing these two key components in a suitable position so that they can work together to achieve precise adjustment of the sweater knitting machine needles. An adjustment mechanism is provided on the outer side of the bracket 2, and a tension mechanism is provided on the outer side of the bracket 2.
[0036] The adjustment mechanism includes a housing 3, which provides a closed protective space for the drive assembly and needle bar crank 5, preventing external dust, debris, etc. from entering and affecting the normal operation of the components. It also serves as a safety protection, preventing operators from accidentally contacting moving parts and causing injury. The drive assembly is fixedly connected to the outside of the housing 3, which is the power source of the adjustment mechanism. The motor transmits power to the needle bar crank 5 through a transmission gear set, thereby driving the entire adjustment mechanism to operate. The operator can control the motor through the control circuit to achieve precise adjustment of the needle bar 9 in the up-down or back-and-forth direction, thereby achieving the purpose of adjusting the stitches of the sweater.
[0037] The output end of the drive component is rotatably connected to the needle bar crank 5, which converts the power output by the drive component into the swinging power of the take-up lever 6. Through its own rotational motion, the take-up lever 6 swings accordingly, thereby adjusting the position of the needle bar 9. This allows the operator to achieve a large range of needle bar adjustment with a small amount of force during operation, improving the efficiency and convenience of adjustment. The outer side of the needle bar crank 5 is rotatably connected to the take-up lever 6. Driven by the needle bar crank 5, the take-up lever 6 swings around the connecting pin to the needle bar crank 5. When it is necessary to adjust the stitches, the operator rotates the adjustment knob 7, and the rotational motion of the adjustment knob 7 is transmitted to the needle bar 9 through the take-up lever 6, thereby changing the position of the needle bar 9 and achieving fine adjustment of the sweater stitches.
[0038] An adjustment knob 7 is fixedly connected to the outer side of the take-up lever 6 for manually adjusting the depth of the stitches. When fine adjustments to the stitches of the sweater are needed, the operator only needs to turn the adjustment knob 7, which will cause the fixed slider 8 to move up and down along the bracket 2 through the thread transmission, thereby driving the needle bar 9 to move accordingly, achieving precise adjustment of the stitch depth. The fixed slider 8 is fixedly connected to the outer side of the adjustment knob 7, providing a stable sliding guide for the needle bar 9, ensuring that the needle bar 9 remains vertical and stable during up and down movement, avoiding tilting or shaking. On the other hand, through cooperation with the nut 10, the position of the needle bar 9 on the bracket 2 can be precisely adjusted, thereby achieving adjustment of the stitch density and depth of the sweater.
[0039] The fixed slider 8 is internally connected to a needle bar 9, which, under the action of the drive assembly and adjustment mechanism, drives the needle 14 to move up and down or back and forth, thereby completing the knitting action of the sweater. By adjusting the position of the fixed slider 8, the movement amplitude and position of the needle bar 9 can be changed, thereby adjusting the depth of the sweater stitches. During the knitting process, the stable movement of the needle bar 9 is crucial to ensuring the knitting quality. A nut 10 is fixedly connected to the outer side of the fixed slider 8. By tightening the nut 10, sufficient friction and pressure are generated between the fixed slider 8 and the bracket 2, thereby fixing the fixed slider 8 in a specific position. During the adjustment process, the nut 10 can keep the position of the fixed slider 8 stable and provide reliable support for the movement of the needle bar 9.
[0040] Two needle bar sleeves 11 are fixedly connected to the left and right sides of the needle bar 9. They fit tightly with the needle bar 9 and provide guidance and support for the needle bar 9, ensuring that the needle bar 9 remains vertical or horizontal during movement and avoiding deviation or swaying. A thread take-up lever 12 is rotatably connected to the outer side of the needle bar crank 5. Driven by the needle bar crank 5, the thread take-up lever 12 swings back and forth around the pin shaft, thereby driving the thread take-up lever 13 to move accordingly. A thread take-up lever 13 is fixedly connected to the outer side of the thread take-up lever 12. Driven by the thread take-up lever 12, it swings around the connection point with the thread take-up lever 12, driving the needle 14 to move up and down or back and forth, thereby realizing the take-up and transfer of the knitting thread. Driven by the thread take-up lever 13, the needle 14 can accurately draw the yarn from the yarn supply device and deliver it to the knitting area, ensuring the normal progress of the knitting process.
[0041] A needle 14 is fixedly connected to the bottom of the needle bar 9. Driven by the needle bar 9, the needle moves along a set trajectory to pick up the yarn and form a loop, thus completing the knitting action. During the knitting process, the movement accuracy and stability of the needle 14 directly affect the knitting quality and effect of the sweater. The tension mechanism includes an unwinding roller 17, which is a yarn storage and release device. The unwinding roller 17 releases the yarn evenly, providing a stable yarn supply for the knitting process. The rotation accuracy and stability of the unwinding roller 17 directly affect the unwinding quality of the yarn and the subsequent knitting effect. If the unwinding is uneven, it may lead to defects in the knitted sweater, such as inconsistent loop sizes and disordered patterns.
[0042] A motor 18 is fixedly connected to one side of the inside of the bracket 2. It provides power for the entire tension adjustment process. By precisely controlling its speed and direction, the motor 18 can drive the drive shaft 19 to rotate. Then, through the belt 21, the pulley 20 and other transmission components, the speed of the unwinding roller 17 can be adjusted, thereby controlling the unwinding speed and tension of the yarn. This is crucial to ensuring the knitting quality of the wool sweater. The output end of the motor 18 is rotatably connected to the drive shaft 19, which transmits the power output by the motor 18 to the pulley 20, thereby driving the unwinding roller 17. The speed and direction of the drive shaft 19 directly affect the speed and direction of the pulley 20, and thus affect the unwinding speed and tension of the yarn. Therefore, the transmission accuracy and stability of the drive shaft 19 are required to be high.
[0043] A pulley 20 is rotatably connected to one side of the outer wall of the drive shaft 19. The power transmitted from the drive shaft 19 is transmitted to the unwinding roller 17 via the belt 21. During the transmission process, the pulley 20 drives the belt 21 to move through the friction between the pulley 20 and the belt 21, thereby driving the unwinding roller 17. The rotation speed and direction of the pulley 20 determine the speed and direction of the belt 21, which in turn affects the unwinding speed and tension of the yarn. The belt 21 is coupled to the outer wall of the pulley 20 to connect the pulley 20 and the unwinding roller 17 and transmit the power of the pulley 20 to the unwinding roller 17. The outer wall of the unwinding roller 17 is fixedly connected to one side of the outer wall of the bracket 2. The outer wall of the motor 18 is also fixedly connected to one side of the outer wall of the bracket 2.
[0044] Reference Figures 3 to 4 The drive assembly includes a motor 4, which is externally fixed to the outside of the housing 3. The needle bar crank 5 is externally rotatably connected to the outside of the motor 4. A needle hole 15 is provided on one side of the base plate 1 to ensure that the needle 14 can slide freely in the needle hole 15. The position of the needle hole 15 is precisely designed to match the movement trajectory of the needle 14 and the hook 16, ensuring the smooth progress of the knitting process. The hook 16 is rotatably connected inside the needle hole 15. During the knitting process, the hook 16 plays the role of assisting in taking up the yarn and knitting. When the take-up lever 13 swings, the hook 16 will cooperate with the action of the take-up lever 13 to hook the yarn from the yarn storage device and bring it into the knitting area, so that the yarn is wound on the needle 14 in a certain pattern to form a loop, thereby completing the knitting action. The use of the hook 16 can improve the knitting efficiency and quality, making the knitted sweater more uniform and beautiful.
[0045] The needle 14 is externally slidably connected to the inside of the needle hole 15, and the needle bar crank 5 is externally rotatably connected to the inside of the housing 3. The outside of the housing 3 is fixedly connected to the outside of the bracket 2. A groove 22 is provided on the front inside of the bracket 2 to ensure that the follower block 23 can slide smoothly within the groove 22. Limit devices are provided at both ends of the groove 22 to prevent the follower block 23 from disengaging from the groove 22 during sliding, ensuring the safety and stability of the entire mechanism. The follower block 23 is slidably connected inside the groove 22 and is installed inside the groove 22. It slides along the groove 22 as the yarn tension changes. When the yarn tension changes, the follower block 23 moves within the groove 22, thereby achieving precise control of the yarn tension.
[0046] Reference Figures 5 to 6Two linear slide rails 24 are fixedly connected to the left and right sides of the outer wall of the bracket 2, providing high-precision linear motion guidance for the pneumatic slider 25. During the tension adjustment process, the pneumatic slider 25 moves linearly along the linear slide rails 24, thereby driving the connecting plate 26 and tension roller 27 to move, thus realizing the adjustment of yarn tension. Two pneumatic sliders 25 are slidably connected to the left and right sides of the outer wall of the two linear slide rails 24. Under the action of air pressure, the pneumatic slider 25 can move linearly on the linear slide rails 24. By adjusting the size and direction of the air pressure, the precise position control and speed adjustment of the pneumatic slider 25 can be realized. The movement of the pneumatic slider 25 drives the connecting plate 26 and tension roller 27 to move, thereby adjusting the yarn tension.
[0047] A connecting plate 26 is fixedly connected to one side of the outer wall of the two pneumatic sliders 25, which serves to connect and support the tension roller 27, connecting the tension roller 27 to the pneumatic slider 25 so that the tension roller 27 can move with the movement of the pneumatic slider 25. The tension roller 27 is fixedly connected to one side of the outer wall of the connecting plate 26. During the knitting process of the sweater, the tension roller 27 applies a certain pressure by contacting the yarn, thereby controlling the tension of the yarn. When the yarn passes through the tension roller 27, the yarn is subjected to a certain resistance due to the friction and squeezing action between the tension roller 27 and the yarn, thereby achieving the adjustment of the yarn tension. An auxiliary roller 28 is fixedly connected to one side of the outer wall of the bracket 2. Before assisting the tension roller 27, the auxiliary roller 28 can perform preliminary sorting and guiding of the yarn, so that the yarn can enter the tension roller 27 more smoothly and reduce the yarn tangling and twisting.
[0048] Working principle: When the needle adjustment component of the wool sweater knitting machine is working, motor 4, as the drive component, provides power to the adjustment mechanism. Its power is transmitted to the needle bar crank 5 through the transmission gear set. The needle bar crank 5 rotates, causing the take-up lever 6 and the take-up lever 12 to swing. The operator turns the adjustment knob, and through the take-up lever 6, the rotational motion is transmitted to the needle bar 9 to adjust the position of the needle bar 9. The fixed slider 8 provides a sliding guide for the needle bar 9 and, together with the nut 10, precisely adjusts the position of the needle bar 9 on the bracket 2. The needle bar 9 is fitted with a needle bar sleeve 11 to ensure stable movement. The take-up lever 12 drives the take-up lever 13 to swing, which in turn drives the needle 14 to move, picking up and feeding the yarn. At the same time, the hook 16 rotates in the needle hole 15, working with the take-up lever 13 to hook the yarn out and bring it into the knitting area, so that the yarn is wound on the needle 14 to form a loop. Driven by the needle bar 9, the needle 14 moves along the set trajectory to complete the knitting action. Throughout the process, the needle 14 slides freely in the needle hole 15, thereby completing the knitting of the sweater and the adjustment of the stitches.
[0049] During the knitting process of a wool sweater, the unwind roller 17 serves as a yarn storage and release device, evenly releasing the yarn to provide a stable supply for knitting. The motor 18 on one side of the support 2 provides power for tension adjustment. By precisely controlling its speed and direction, it drives the drive shaft 19 to rotate. The drive shaft 19, through the belt 21 and pulley 20, adjusts the speed of the unwind roller 17, thereby controlling the unwinding speed and tension of the yarn. When the yarn tension changes, the follower block 23 in the front groove 22 inside the support 2 slides accordingly, achieving precise control of the yarn tension. Simultaneously, the support... The linear guide rails 24 on both sides of the outer wall of the frame 2 provide high-precision linear motion guidance for the pneumatic slider 25. By adjusting the air pressure and direction, the pneumatic slider 25 is controlled to move linearly on the linear guide rails 24. The pneumatic slider 25 drives the connecting plate 26 and the tension roller 27 to move. The tension roller 27 contacts the yarn and applies pressure to the yarn through friction and squeezing to adjust the yarn tension. In addition, before the yarn enters the tension roller 27, the auxiliary roller 28 on the outer side of the bracket 2 performs preliminary sorting and guidance of the yarn, helping the yarn to enter the tension roller 27 more smoothly and reducing entanglement and twisting.
