[0014] Preferably, the outer side of the circular slider is slidably connected to the inner side of the limit cylinder, the inner side of the circular slider is fixedly connected to the outer wall of the slide rod, the inner side of the pressure plate is slidably connected to the top of the hollow rod, the inner side of the insertion cylinder is plugged into the top of the rotating rod, and the top of the rotating rod is just inserted into the insertion cylinder. At this time, rotating the insertion cylinder can drive the rotating rod to rotate together.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention arranges a wire-releasing device, rotates the turntable on the fixed seat, and rotates the required winding reel to the side close to the weaving frame. At this time, the turntable drives the limit block at its bottom to rotate. Six evenly distributed arc grooves are opened on the surface of the limit block. When the limit block rotates, the protrusion fits with the groove on the elastic support frame of the compression spring. The compression spring ensures that the protrusion is tightly against the surface of the limit block by constant elastic force, maintaining a stable contact state, so that the rotation step of the turntable is locked at sixty degrees, preventing it from accidentally rotating when the weaving machine is working and causing position displacement.

[0017] 2. The present invention sets a fixing component and inserts the winding drum into the surface of the hollow rod in the friction component. At this time, the bottom of the winding drum contacts the ball on the surface of the fixing plate, which can reduce the friction resistance generated when the winding drum rotates with the release of the yarn. Then, the winding drum can be limited by the limiting component fixed on the mounting plate.

[0018] 3. The present invention sets a limit assembly, and pulls the slide rod to make the circular slider in the clamping component slide upward in the limit cylinder. At this time, the tension spring is stretched under the restriction of the rotating block. When the pressure plate is disengaged from the hollow rod, the slide rod can be rotated, so that the limit rotating block rotates with the slide rod, and the pressure plate is stuck in the limit groove, thereby preventing the clamping component from interfering with the process of inserting the winding reel.

[0019] 4. The present invention sets a limit assembly. After the winding drum is placed, the clamping component slides out of the limit groove. At this time, the clamping component can be reset under the elastic force of the tension spring. At this time, the annular pressure block can be pressed on the top of the winding drum. At the same time, the annular pressure block cooperates with the ball to reduce the friction resistance generated when the winding drum rotates.

[0020] 5. The present invention provides a friction component, and rotating the insert cylinder can drive the rotating rod to rotate together. While rotating, the rotating rod slides along the inner side of the internal threaded column and drives the upper slider and the lower slider to move downward. At this time, under the squeezing action of the upper slider and the lower slider, the friction plate can slide outward along the inner wall of the hollow rod and contact the inner wall of the winding drum, thereby controlling the rotational resistance of the winding drum, thereby controlling the speed at which the yarn is released from the winding drum, and allowing the yarn to always enter the weaving area in a stable tension state.

[0021] 6. The present invention sets a wire guide component. As the weaving action proceeds, the yarn begins to be gradually tightened. Because the yarn passes over the guide wheel, the tension of the yarn acts on the guide wheel, thereby driving the slide frame to slide downward along the guide frame. At this time, the traction rope fixed on the pay-off drum will be gradually released as the slide frame slides downward, and the mainspring will be wound and tightened. As a result, the guide wheel and the slide frame can make corresponding sliding responses in real time according to the change in tension, ensuring that the yarn can be continuously and smoothly supplied to the weaving position. At the same time, it also ensures that the yarn tension can be naturally adjusted to a certain extent, avoiding the influence of the weaving quality due to excessive or insufficient yarn tension.

[0022] 7. The present invention provides a booster wheel, which is rotatably connected to the bottom of the housing and plays an important auxiliary role. When the traction rope is released or retracted with the rotation of the pay-off drum and the sliding of the sliding frame, the booster wheel can change the force direction and force state of the traction rope by its own rotation, so that the traction rope can be released or retracted more smoothly when passing through the booster wheel, effectively reducing the resistance encountered by the traction rope during the movement.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0034] Example: See Figure 1 - Fig. 9 The present invention provides a technical solution: a sock knitting mechanism, comprising: a base 1, a knitting frame 2 is fixedly connected to the top of the base 1, a rotating ring 4 is rotatably connected to the outer side of the knitting frame 2, a threading plate 5 is fixedly connected to the outer side of the rotating ring 4, a gear ring 3 is fixedly connected to the bottom of the rotating ring 4, a driving motor 6 is fixedly connected to the outer side of the base 1, a driving gear 7 is fixedly connected to the output end of the driving motor 6, and the gear ring 3 is meshed with the driving gear 7. The sock knitting mechanism is mainly composed of a base 1, a knitting frame 2, and a matching wire release device 8. When working, the driving motor 6 is started, and the driving gear 7 drives the gear ring 3 to rotate, thereby causing the rotating ring 4 to perform a circular motion around the knitting frame 2. The rotating ring 4 drives the threading plate 5 to move in coordination, and at the same time, the knitting needles installed on the knitting frame 2 participate in the key knitting action as the rotating ring 4 rotates. The threading plate 5 can guide the yarn to move according to a predetermined knitting trajectory during the rotation process, and the wire release device 8 is responsible for releasing the knitting wire in an orderly manner. The various parts cooperate with each other to realize the knitting process of socks;

[0035] The wire-releasing device 8 has a bottom fixedly connected to the top of the base 1, and is located at the top of the braiding frame 2. The wire-releasing device 8 includes a fixed seat 81, and a turntable 82 is rotatably connected to the outer side of the fixed seat 81. A limiting block 83 is fixedly connected to the bottom of the turntable 82, and a protrusion 84 is slidably connected to the outer side of the limiting block 83. A compression spring 85 is fixedly connected to the outer side of the protrusion 84. A fixing assembly 86 is fixedly connected to the top of the turntable 82, and a winding drum 87 is sleeved on the outer side of the fixing assembly 86. A limiting assembly 88 is fixedly connected to the outer side of the fixing assembly 86, and winding drums 87 of different specifications and colors are respectively fixed on the surface of the fixing assembly 86, and then the winding is adjusted by the limiting assembly 88. The fixing process of the limiting assembly 88 can be completed by limiting the drum 87. When the position of the winding drum 87 needs to be adjusted, the turntable 82 on the fixing seat 81 can be rotated to rotate the required winding drum 87 to the side close to the knitting frame 2. At this time, the turntable 82 drives the limiting block 83 at its bottom to rotate. The surface of the limiting block 83 is provided with six evenly distributed arc grooves. When the limiting block 83 rotates, the protrusion 84 fits with the groove on the elastic support frame of the compression spring 85. The compression spring 85 ensures that the protrusion 84 is tightly against the surface of the limiting block 83 by constant elastic force, maintaining a stable contact state, so that the rotation step of the turntable 82 is locked at 60 degrees to prevent it from accidentally rotating when the knitting machine is working and causing position deviation;

[0036] The fixing assembly 86 includes a mounting plate 861, a fixing plate 862 is fixedly connected to the top of the mounting plate 861, a guide frame 863 is fixedly connected to the outer side of the fixing plate 862, a lead component 865 is fixedly connected to the bottom of the guide frame 863, a friction component 864 is fixedly connected to the top of the mounting plate 861, and a ball 866 is slidably connected to the top of the fixing plate 862. When fixing the bobbin 87, the bobbin 87 is inserted into the surface of the hollow rod 641 in the friction component 864. At this time, the bottom of the bobbin 87 contacts the ball 866 on the surface of the fixing plate 862, which can reduce the friction resistance generated when the bobbin 87 rotates with the release of the yarn, and then the bobbin 87 can be limited by the limiting assembly 88 fixed on the mounting plate 861;

[0037] The friction component 864 includes a hollow rod 641, the inner side of the hollow rod 641 is fixedly connected with an internal thread column 642, the inner side of the internal thread column 642 is threadedly connected with a rotating rod 643, the outer side of the rotating rod 643 is rotatably connected with an upper slider 644 and a lower slider 645, the lower slider 645 is located at the bottom of the upper slider 644, the inner wall of the hollow rod 641 is slidably connected with a friction plate 646, the bottom of the fixed seat 81 is fixedly connected to the top of the base 1, the bottom of the protrusion 84 is slidably connected to the outer side of the fixed seat 81, the end of the compression spring 85 away from the protrusion 84 is fixedly connected to the outer side of the fixed seat 81, the bottom of the mounting plate 861 is fixedly connected to the top of the rotating disk 82, the bottom of the hollow rod 641 is fixedly connected to the top of the fixed plate 862, the outer sides of the upper slider 644 and the lower slider 645 The walls are slidably connected to the inner side of the hollow rod 641, the outer side of the upper slider 644 is slidably connected to the outer side of the friction plate 646, and the side of the friction plate 646 away from the upper slider 644 is slidably connected to the outer side of the lower slider 645. Rotating the insert cylinder 503 can drive the rotating rod 643 to rotate together. While rotating, the rotating rod 643 slides along the inner side of the internal threaded column 642 and drives the upper slider 644 and the lower slider 645 to move downward. At this time, under the squeezing action of the upper slider 644 and the lower slider 645, the friction plate 646 can slide outward along the inner wall of the hollow rod 641 and contact with the inner wall of the winding drum 87, thereby controlling the rotational resistance of the winding drum 87, thereby controlling the speed at which the yarn is released from the winding drum 87, so that the yarn always enters the weaving area with a stable tension state.

[0038] The lead component 865 includes an outer shell 651, the inner side of the outer shell 651 is fixedly connected to a mainspring 652, the outer side of the mainspring 652 is fixedly connected to a pay-off drum 653, the outer wall of the pay-off drum 653 is fixedly connected to a traction rope 654, the bottom end of the traction rope 654 is fixedly connected to a sliding frame 656, the inner side of the sliding frame 656 is rotatably connected to a guide wheel 657, the bottom of the outer shell 651 is rotatably connected to a booster wheel 655, the outer side of the outer shell 651 is fixedly connected to the top of the guide frame 863, the inner side of the guide frame 863 is slidably connected to the outer side of the sliding frame 656, the two sides of the pay-off drum 653 are rotatably connected to the inner side of the outer shell 651, after the yarn is released from the winding drum 87, it will enter the lead component 865 and pass through the top of the guide wheel 657 of the lead component 865, and then be directly led to the weaving area where the threading plate 5 is located, ready to participate in the sock weaving work. As the knitting action proceeds, the yarn begins to be gradually tightened. Because the yarn passes over the guide wheel 657, the tension of the yarn will act on the guide wheel 657, thereby driving the sliding frame 656 to slide down along the guide frame 863. At this time, the traction rope 654 fixed on the pay-off drum 653 will be gradually released as the sliding frame 656 slides down, and the spring 652 will be wound and tightened, so that the guide wheel 657 and the sliding frame 656 can make corresponding sliding responses in real time according to the change of tension, ensuring that the yarn can be continuously and smoothly supplied to the knitting position, and at the same time ensuring that the yarn tension can be naturally adjusted to a certain extent, avoiding the influence of the knitting quality due to excessive or too small yarn tension; among them, the booster wheel 655 rotatably connected to the bottom of the shell 651 plays an important auxiliary role. When the traction rope 654 is released or retracted with the rotation of the pay-off drum 653 and the sliding of the sliding frame 656, the booster wheel 655 can change the force direction and force state of the traction rope 654 through its own rotation, so that the traction rope 654 can be released or retracted more smoothly when passing through the booster wheel 655, effectively reducing the resistance encountered by the traction rope 654 during the movement.

[0039] The limiting assembly 88 includes a limiting cylinder 881, the inner side of the limiting cylinder 881 is rotatably connected to a rotating block 882, the top of the rotating block 882 is fixedly connected to a tension spring 887, the top of the tension spring 887 is fixedly connected to a clamping component 885, the inner side of the clamping component 885 is rotatably connected to a slide rod 883, the outer wall of the slide rod 883 is slidably connected to a limiting rotating block 884, a limiting groove 886 is provided in the wall of the limiting cylinder 881, the bottom of the limiting cylinder 881 is fixedly connected to the top of the mounting plate 861, the inner side of the clamping component 885 is slidably connected to the inner wall of the limiting cylinder 881, the outer wall of the slide rod 883 is slidably connected to the inner wall of the rotating block 882, and the outer side of the limiting rotating block 884 is rotatably connected to the top of the limiting cylinder 881. The clamping component 885 includes a circular slider 501, the outer side of the circular slider 501 is fixedly connected to a pressure plate 502, the inner side of the pressure plate 502 is rotatably connected to an insert cylinder 503, the bottom of the pressure plate 502 is rotatably connected to an annular pressure block 504, the outer side of the circular slider 501 is slidably connected to the inner side of the limiting cylinder 881, the inner side of the circular slider 501 is fixedly connected to the outer wall of the slide bar 883, the inner side of the pressure plate 502 is slidably connected to the top of the hollow rod 641, the inner side of the insert cylinder 503 is plugged into the top of the rotating rod 643, and the circular slider 501 in the clamping component 885 slides upward in the limiting cylinder 881 by pulling the sliding rod 883. The tension spring 887 is stretched under the control, and when the pressure plate 502 is disengaged from the hollow rod 641, the slide bar 883 can be rotated, so that the limit rotating block 884 rotates together with the slide bar 883, and the pressure plate 502 is stuck in the limit groove 886, thereby preventing the clamping component 885 from interfering with the process of placing the winding drum 87; after the winding drum 87 is placed, the clamping component 885 is slid out of the limit groove 886, and the clamping component 885 can be reset under the elastic force of the tension spring 887. At this time, the annular pressure block 504 can be pressed on the top of the winding drum 87, and the annular pressure block 504 cooperates with the ball 866 to reduce the friction resistance generated when the winding drum 87 rotates.

[0040] Working principle:

[0041] When in use, the sock knitting mechanism is mainly composed of a base 1, a knitting frame 2, and a matching wire release device 8. When working, the drive motor 6 is started, and the drive gear 7 drives the gear ring 3 to rotate, thereby causing the rotating ring 4 to perform a circular motion around the knitting frame 2. The rotating ring 4 drives the threading plate 5 to move in coordination, and at the same time, the knitting needles installed on the knitting frame 2 participate in the key knitting action as the rotating ring 4 rotates. The threading plate 5 can guide the yarn to move along a predetermined knitting trajectory during the rotation process, and the wire release device 8 is responsible for releasing the knitting wire in an orderly manner. Each part cooperates with each other to realize the knitting process of the socks.

[0042] When the wire-releasing device 8 is working, the winding reels 87 of different specifications and colors are fixed on the surface of the fixing component 86 respectively, and then the winding reels 87 are limited by the limiting component 88 to complete the fixing process of the limiting component 88. When the position of the winding reel 87 needs to be adjusted, the turntable 82 on the fixing seat 81 can be rotated to turn the required winding reel 87 to the side close to the weaving frame 2. At this time, the turntable 82 drives the limiting block 83 at its bottom to rotate. Six evenly distributed arc grooves are opened on the surface of the limiting block 83. When the limiting block 83 rotates, the protrusion 84 fits with the groove on the elastic support frame of the compression spring 85. The compression spring 85 relies on constant elastic force to ensure that the protrusion 84 is tightly against the surface of the limiting block 83 to maintain a stable contact state, so that the rotation step of the turntable 82 is locked at sixty degrees to prevent it from accidentally rotating when the weaving machine is working and causing position displacement.

[0043] When the bobbin 87 is fixed, the bobbin 87 is inserted into the surface of the hollow rod 641 in the friction component 864. At this time, the bottom of the bobbin 87 contacts the ball 866 on the surface of the fixing plate 862, which can reduce the friction resistance generated when the bobbin 87 rotates with the release of the yarn. Then, the bobbin 87 can be limited by the limiting assembly 88 fixed on the mounting plate 861.

[0044] When limiting, the circular slider 501 in the clamping component 885 slides upward in the limiting cylinder 881 by pulling the sliding rod 883. At this time, the tension spring 887 is stretched under the restriction of the rotating block 882. When the pressure plate 502 is separated from the hollow rod 641, the sliding rod 883 can be rotated, so that the limiting rotating block 884 rotates with the sliding rod 883, and the pressure plate 502 is stuck in the limiting groove 886, so as to prevent the clamping component 885 from interfering with the process of inserting the winding reel 87.

[0045] After the winding drum 87 is placed, the clamping component 885 is slid out of the limiting groove 886. At this time, the clamping component 885 can be reset under the elastic force of the tension spring 887. At this time, the annular pressure block 504 can be pressed on the top of the winding drum 87. At the same time, the annular pressure block 504 cooperates with the ball 866 to reduce the friction resistance generated when the winding drum 87 rotates.

[0046] During this process, the top of the rotating rod 643 is just inserted into the inserting tube 503. At this time, rotating the inserting tube 503 can drive the rotating rod 643 to rotate together. While rotating, the rotating rod 643 slides along the inner side of the internal threaded column 642 and drives the upper slider 644 and the lower slider 645 to move downward. At this time, under the squeezing action of the upper slider 644 and the lower slider 645, the friction plate 646 can slide outward along the inner wall of the hollow rod 641 and contact with the inner wall of the winding drum 87, thereby controlling the rotation resistance of the winding drum 87, thereby controlling the speed of the yarn being released from the winding drum 87, so that the yarn always enters the weaving area with a stable tension state;

[0047] After the yarn is released from the winding drum 87, it will enter the lead-in component 865, pass over the guide wheel 657 of the lead-in component 865, and then be directly led to the weaving area where the threading plate 5 is located, ready to participate in the sock weaving work. As the weaving action proceeds, the yarn begins to be gradually tightened. Because the yarn passes over the guide wheel 657, the tension of the yarn will act on the guide wheel 657, thereby driving the sliding frame 656 to slide down along the guide frame 863. At this time, the traction rope 654 fixed on the unwinding drum 653 will be gradually released as the sliding frame 656 slides down, and at the same time, the mainspring 652 will be wound and tightened, so that the guide wheel 657 and the sliding frame 656 can make corresponding sliding responses in real time according to the change in tension, ensuring that the yarn can be continuously and smoothly supplied to the weaving position, and at the same time ensuring that the yarn tension can be naturally adjusted to a certain extent, avoiding the influence of the weaving quality due to excessive or insufficient yarn tension;

[0048] The booster wheel 655 rotatably connected to the bottom of the housing 651 plays an important auxiliary role. When the traction rope 654 is released or retracted with the rotation of the pay-off drum 653 and the sliding of the sliding frame 656, the booster wheel 655 can change the force direction and force state of the traction rope 654 by its own rotation, so that the traction rope 654 can be released or retracted more smoothly when passing through the booster wheel 655, effectively reducing the resistance encountered by the traction rope 654 during the movement.
