Description

Technical Field

[0001] This application relates to the field of circular knitting machines, and more particularly to a circular knitting machine with yarn supply adjustment function. Background Technology

[0002] Circular knitting machines are commonly used circular weft knitting equipment in the knitting industry. They are mainly used for mass production of tubular or sheet-like knitted fabrics. The cylinder rotates, driving the needles on the needle bed to move up and down. At the same time, the yarn feeder feeds the yarn into the needles, ultimately forming a continuous loop structure to weave the knitted fabric. The distance between the yarn feeder and the cylinder directly affects the stability of the knitting process and the quality of the finished fabric. However, the current yarn feeder distance adjustment requires manual adjustment of each yarn feeder, which lacks a unified quantitative standard, resulting in insufficient precision and low efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a small circular knitting machine with yarn supply adjustment function in order to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows: This application provides a small circular knitting machine with yarn supply adjustment function.

[0005] In one embodiment, a large tray base is included, a syringe is mounted on the large tray base, a support arm is circumferentially arranged on the large tray base, a top seat is mounted on several support arms, and the top seat has an opening for yarn to pass through. The large plate base also has a support, which has a slot. A lifting drive assembly is installed in the slot. The lifting drive assembly includes a housing with a hollow section inside. A shaft is installed in the hollow section and a turbine component is mounted thereon. The housing also has a shaft hole located below the turbine component. One end of the shaft hole extends to the outside of the support. A slot communicating with the hollow section is provided on the shaft hole. A worm gear is rotatably installed in the shaft hole. One end of the worm gear located in the shaft hole is connected to a bearing seat. The teeth of the worm gear pass through the slot and mesh with the turbine component. The other end of the worm gear is located outside the support and is equipped with a handwheel. A rack is also meshed on one side of the turbine component. The box body is also provided with an opening, the rack part is located outside the support and has a receiving part, the receiving part is connected to a ring bracket and located above the syringe, and several yarn nozzles are installed on the ring bracket; By cooperating with the worm gear and turbine components, the portion of the rack located outside the support can be increased or decreased, causing the annular support to move the yarn nozzle closer to or further away from the syringe.

[0006] In one embodiment, the support is further provided with several circumferentially distributed support seats, a portion of which moves inside the support and a portion located outside the support has a receiving plate, and a portion of the annular bracket is connected to the receiving plate. When the annular support moves the yarn nozzle closer to or further away from the syringe, the portion of the support seat located within the holder increases or decreases.

[0007] In one embodiment, the receiving component includes a fixed seat and a movable seat. The fixed seat is disposed on the rack, and a groove is provided on the other side of the movable seat. The fixed seat is provided with a protrusion that is embedded in the groove. By increasing or decreasing the portion of the protrusion that is embedded in the groove, the movable seat can be moved closer to or further away from the fixed seat.

[0008] In one embodiment, a side plate is provided on one side of the support base, and a guide rod is provided on the side of the side plate facing the bracket, with a portion of the guide rod movably mounted on the bracket. When the annular support moves the yarn nozzle closer to or further away from the syringe, the portion of the guide rod located within the support increases or decreases.

[0009] In one embodiment, a support plate is provided at the bottom of the movable seat, and when the annular bracket is connected to the movable seat, the annular bracket is located on the support plate.

[0010] In one embodiment, the handwheel is provided with a number of grooves that are spaced apart along the circumference of the handwheel, and the grooves form anti-slip patterns on the handwheel.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a small circular knitting machine with yarn supply adjustment function. By installing a ring-shaped bracket for mounting the yarn feeder on a receiving component connected to a rack, and because the rack meshes with a worm gear, and the worm gear meshes with a worm, when the operator rotates the handwheel located outside the support, the worm gear can be driven to rotate synchronously. The rotation of the worm gear causes the worm gear to rotate synchronously, thereby driving the rack to move vertically. This causes the ring-shaped bracket to move the yarn feeder closer to or away from the needle cylinder, thereby adjusting the interval between the yarn feeder and the needle cylinder, achieving synchronous adjustment of the yarn supply distance. This solves the problem that existing yarn supply adjustments require individual operation, resulting in low operating efficiency. Attached Figure Description

[0019] Reference Figures 1-4 A small circular knitting machine with yarn supply adjustment function includes a large disc base 1, a needle cylinder 11 mounted on the large disc base 1, a support arm 12 circumferentially arranged on the large disc base 1, a top seat 121 mounted on several support arms 12, and an opening for yarn to pass through the top seat 121. The support arms 12 are arranged circumferentially along the support base 13, and the openings of the top seat 121 are also circumferentially distributed, matching the circular knitting trajectory of the needle cylinder 11, so as to simultaneously provide yarn guidance for multiple yarn nozzles. The large plate base 1 also has a support 13, which has a slot 131. A lifting drive assembly 2 is installed in the slot 131. The lifting drive assembly 2 includes a housing 21, which has a hollow portion 211. A shaft 22 is provided in the hollow portion 211 and a turbine component 23 is installed therein. The housing 21 also has a shaft hole 212 located below the turbine component 23. One end of the shaft hole 212 extends to the outside of the support 13. The shaft hole 212 has a slot 2121 that communicates with the hollow portion 211. A worm gear 25 is rotatably installed in the shaft hole 212. One end of the worm gear 25 located in the shaft hole 212 is connected to a bearing seat. The teeth of the worm gear 25 pass through the slot 2121 and communicate with the turbine component. The worm gear 25 is located outside the support 13 and is equipped with a handwheel 251. A rack 24 is also engaged on one side of the turbine 23. The turbine 23 and the worm gear 25 adopt a worm-driven turbine meshing structure, which can realize micro-adjustment. When the handwheel 251 is turned, the small rotation of the worm gear 25 will be converted into the slow rotation of the turbine 23, which will drive the rack 24 to slowly rise and fall to realize the millimeter-level adjustment of the distance between the yarn nozzle and the needle cylinder 11, accurately adapting to the yarn supply needs of different fabrics. At the same time, the turbine worm gear transmission has self-locking property. After the adjustment is completed, the rack 24 will not move in the opposite direction due to equipment vibration or yarn tension, ensuring that the yarn nozzle position is constant and avoiding the yarn supply position deviation during the knitting process. The housing 21 is also provided with an opening 2131. Part of the rack 24 is located outside the support 13 and has a receiving component 26. The receiving component 26 is connected to the annular bracket 3 and is located above the needle cylinder 11. Several yarn nozzles are installed on the annular bracket 3. Through the cooperation of the worm gear 25 and the turbine 23, the part of the rack 24 located outside the support 13 can be increased or decreased, so that the annular bracket 3 drives the yarn nozzles to move closer to or away from the needle cylinder 11. The rack 24 is rigidly connected to the annular bracket 3 through the receiving component 26. The movement of the rack 24 will directly drive the annular bracket 3 to move as a whole. Since the annular bracket 3 is ring-shaped and coaxial with the needle cylinder 11, all the yarn nozzles on it will move closer to or away from the needle cylinder 11 synchronously in the circumferential direction. Therefore, uneven yarn supply position caused by the adjustment of a single yarn nozzle is avoided, and the yarn supply amount and yarn supply angle of all needles are consistent during the knitting process.

[0020] Based on the above structure, the operator rotates the handwheel 251, causing the receiving component 26 to move the annular support 3 above the needle cylinder 11. Yarn feeders are then placed sequentially on the annular support 3 for weaving operations. When the height of the yarn feeder needs to be adjusted, the handwheel 251 is rotated to drive the worm gear 25, which in turn drives the turbine 23 meshing with the worm gear 25. The other end of the turbine 23 is connected to a rack 24. Therefore, when the turbine 23 rotates clockwise or counterclockwise, the rack 24 can move vertically, allowing the annular support 3 to move closer to or further away from the needle cylinder 11. This enables synchronous adjustment of the yarn feeders on the annular support 3, adapting to different fabric requirements. This solves the problem that existing small circular knitting machines require operators to adjust each yarn feeder individually, resulting in a cumbersome operation and potential for inaccurate operation.

[0021] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The support 13 is also provided with several circumferentially distributed support seats 14. Part of the support seat 14 moves inside the support 13, and the part located outside the support 13 has a receiving plate. Part of the annular bracket 3 is connected to the receiving plate. When the annular bracket 3 drives the yarn nozzle to move closer to or away from the needle cylinder 11, the part of the support seat 14 inside the support 13 increases or decreases. When the annular bracket 3 moves closer to the needle cylinder 11, the exposed part of the support seat 14 experiences increased force, and the part embedded inside the support 13 increases, reducing the exposed length to maintain stable support. When the annular bracket 3 moves away from the needle cylinder 11, the exposed part of the support seat 14 experiences decreased force, and the part embedded inside the support 13 decreases, increasing the exposed length to continuously support the annular bracket 3. This provides dynamically adaptable support force for the annular bracket 3, preventing it from shaking or sagging during yarn feeding adjustment, ensuring the stability of the yarn nozzle position, and thus ensuring yarn feeding accuracy. A side plate 141 is provided on one side of the support base 14, and a guide rod 1411 is provided on the side of the side plate 141 facing the support base 13. Part of the guide rod 1411 is movable on the support base 13. When the annular bracket 3 moves the yarn nozzle closer to or away from the needle cylinder 11, the portion of the guide rod 1411 inside the support base 13 increases or decreases. When the support base 14 is embedded into the support base 13, the side plate 141 moves closer to the support base 13 simultaneously, and the portion of the guide rod 1411 penetrating the support base 13 increases. When the support base 14 extends out of the support base 13, the side plate 141 moves away from the support base 13 simultaneously, and the portion of the guide rod 1411 penetrating the support base 13 decreases. The guide rod 1411 always moves in a straight line, which can limit the movement trajectory of the support base 14 and prevent it from shifting laterally during movement. The rigid guide ensures the movement accuracy of the support base 14, thereby ensuring the stability of the adjustment trajectory of the annular bracket 3 and the yarn nozzle, and preventing deviations in the yarn supply position.

[0022] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The receiving component 26 includes a fixed seat 261 and a movable seat 262. The fixed seat 261 is mounted on the rack 24. A groove is provided on the other side of the movable seat 262. The fixed seat 261 has a protrusion 2611 that is embedded in the groove. By increasing or decreasing the portion of the protrusion 2611 embedded in the groove, the movable seat 262 can be moved closer to or further away from the fixed seat 261. When the movable seat 262 is pushed, the protrusion 2611 slides in the groove, and the portion embedded in the groove increases, causing the movable seat 262 to move closer to the fixed seat 261. Thus, by adjusting the distance, ring-shaped brackets 3 of different sizes can be placed, improving the flexibility of use.

[0023] In one embodiment, reference is made to Figure 1 and Figure 4 The bottom of the movable seat is provided with a support plate 2621. When the annular bracket 3 is connected to the movable seat 262, the annular bracket 3 is located on the support plate 2621. The support plate 2621 is used to support the annular bracket 3 from the bottom, thereby playing a supporting role for the annular bracket 3 and further improving the stability of the annular bracket 3 when connected.

[0024] In one embodiment, reference is made to Figure 1 and Figure 2The handwheel 251 is provided with grooves 2511. Several grooves 2511 are provided and are distributed at intervals along the circumference of the handwheel 251. Several grooves 2511 form anti-slip textures on the handwheel 251. When the operator rotates the handwheel 251, the fingers come into contact with the concave and convex textures of the grooves 2511, greatly increasing the friction and avoiding slippage caused by sweaty hands or uneven force. At the same time, the anti-slip textures can help the operator perceive the rotation angle, improve the accuracy of manual adjustment, reduce the problem of over-adjustment or under-adjustment, and reduce human operation error.
