Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a double-needle integrated anti-tangling linkage mechanism for stockings. Background Technology

[0002] In the field of knitting machinery, sock knitting machines are specialized equipment used for knitting tubular fabrics such as socks. With advancements in textile technology, sock knitting machines have evolved from the initial single-cylinder circular knitting machines to today's double-cylinder circular knitting machines, capable of knitting more complex socks with rib knit structures. Long stockings, especially knee-high or over-the-knee socks, place higher demands on knitting techniques and equipment due to their greater length. During the knitting process of long stockings, the stocking gradually elongates and suspends below the cylinder, forming a flexible tubular structure.

[0003] In existing technologies, when sock knitting machines are used to knit long stockings, a long-standing and difficult-to-solve problem arises—the tangling and knotting of the stocking body during the knitting process. Specifically, when the sock knitting machine begins, the sock cuff and upper part of the sock body rotate and knit under the drive of the cylinder. As the knitting length increases, the sock body gradually becomes longer. Because the sock itself is knitted from flexible yarn, the lower half (i.e., the lower section of the sock body away from the cylinder) often lags behind the upper half driven by the cylinder in rotation speed due to gravity and inertia, or even stops rotating. This inconsistent rotation speed between the upper and lower parts causes the lower half of the sock body to twist and fold, leading to tangling with itself or surrounding parts, eventually forming a knot. Once tangling occurs, it can cause knitting to stop, requiring manual cleaning, or even result in irreparable creases, runs, or holes in the sock body, seriously affecting product quality and production efficiency. Especially in double-cylinder sock knitting machines, the torsional torque on the sock body is more complex due to the coordinated movement of the two cylinders, making the tangling problem even more prominent. In existing sock machine designs, to address this issue, operators typically need to frequently observe and intervene manually in the early stages of entanglement. This not only increases labor costs but also severely limits the continuous and automated production of socks.

[0004] Therefore, there is an urgent need in this field to develop a linkage mechanism that can effectively prevent socks from tangling during the knitting process, so as to ensure the continuity and stability of the sock knitting process and improve product quality and production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a double-needle integrated anti-tangling linkage mechanism for stockings to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] This invention provides a double-needle integrated anti-tangling linkage mechanism for stockings, including a stocking machine, wherein the bottom of the stocking machine is provided with a needle cylinder for knitting stockings, and further comprising:

[0008] An anti-tangle rotating cylinder is coaxially disposed below the syringe.

[0009] A synchronous drive device is connected to the anti-tangling rotating cylinder for driving the anti-tangling rotating cylinder to rotate;

[0010] A suction guide device is connected below the anti-tangle rotating cylinder and is used to generate a downward suction force during the knitting process of stockings, so that the stocking body extends vertically downward and rotates synchronously with the anti-tangle rotating cylinder.

[0011] An electronic control system is electrically connected to the synchronous drive device and controls the rotation speed of the anti-tangling rotating cylinder to be consistent with the rotation speed of the syringe assembly.

[0012] Preferably, a connecting tube is mounted on the top of the anti-tangle rotating cylinder via a first bearing, the connecting tube being connected to the syringe, and the first bearing being mounted on the top of the anti-tangle rotating cylinder via a first bearing seat.

[0013] Preferably, the synchronous drive device includes a drive motor, which is mounted on the side of the motor support frame via a motor mounting plate. The output end of the drive motor is fixedly connected to a small synchronous pulley, and a large synchronous pulley is coaxially fixed on the outer wall of the anti-entanglement rotating cylinder. A synchronous belt is tensioned between the small synchronous pulley and the large synchronous pulley.

[0014] Preferably, a cover plate is fastened to the top of the motor mounting plate.

[0015] Preferably, the suction guiding device includes a sock suction box, the top of which is connected to the bottom of the anti-tangling rotating cylinder via a second bearing, the second bearing being mounted on the bottom of the anti-tangling rotating cylinder via a second bearing seat, and the side of the sock suction box being connected to a suction pipe and a discharge pipe via a negative pressure generator.

[0020] The present invention achieves the following beneficial technical effects compared to the prior art:

[0021] The present invention provides a double-needle integrated anti-tangling linkage mechanism for stockings, which effectively prevents stockings from tangling and knotting during the knitting process by setting an anti-tangling rotating cylinder coaxially with the needle cylinder and a suction guide device connected below the anti-tangling rotating cylinder. The anti-tangling rotating cylinder, driven by a synchronous drive device and precisely controlled by an electronic control system, rotates synchronously with the needle cylinder, providing a continuously rotating external guide support for the sock body suspended below the needle cylinder. The downward suction generated by the suction guide device keeps the sock body vertically tensioned in the direction of gravity and rotates synchronously with the anti-tangling rotating cylinder, thus completely solving the problem of lag and twisting in the lower half of the sock due to its increased length. A connecting pipe and a first bearing enable flexible connection between the anti-tangling rotating cylinder and the needle cylinder, resulting in a compact structure and smooth rotation. An observation window on the side of the suction box allows operators to monitor the sock body's condition and handle debris in real time. A sock-blocking cylinder, working in conjunction with the rotating ring, can promptly block the sock body's path when knitting begins or when an abnormality needs to be addressed, improving the equipment's operational convenience and safety. This mechanism ensures the continuity and stability of the knitting process, significantly improving the product quality and production efficiency of long socks while reducing manual intervention and maintenance costs.

[0030] The purpose of this invention is to provide a double-needle integrated anti-tangling linkage mechanism for stockings to solve the problems existing in the prior art.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1:

[0033] Please see Figures 1 to 4This invention provides a double-needle integrated anti-tangling linkage mechanism for stockings, including a stocking machine (not shown in the figure), an anti-tangling rotating cylinder 1, a synchronous drive device, a suction guide device, and an electrical control system (not shown in the figure). The stocking machine has a needle cylinder at its bottom for knitting stockings. The anti-tangling rotating cylinder 1 is coaxially disposed below the needle cylinder. The synchronous drive device is driven by the anti-tangling rotating cylinder 1 and drives it to rotate. The suction guide device is connected below the anti-tangling rotating cylinder 1 and generates a downward suction force during the stocking knitting process, causing the stocking body to extend vertically downwards and rotate synchronously with the anti-tangling rotating cylinder 1. The electrical control system is electrically connected to the synchronous drive device and controls the rotation speed of the anti-tangling rotating cylinder 1 to be consistent with the rotation speed of the needle cylinder.

[0034] Furthermore, such as Figure 1 and Figure 3 As shown, to achieve a flexible connection between the anti-tangle rotating cylinder 1 and the sock machine cylinder, ensuring that they rotate coaxially without interfering with each other, a connecting tube 22 is installed on the top of the anti-tangle rotating cylinder 1 via a first bearing 21. The upper end of the connecting tube 22 is connected to the sock machine cylinder, and the first bearing 21 is mounted on the top of the anti-tangle rotating cylinder 1 via a first bearing seat 23. With this structure, the anti-tangle rotating cylinder 1 can rotate freely relative to the connecting tube 22 and the cylinder, while the connecting tube 22 rotates together with the cylinder, providing a smooth transition channel for the sock body to enter the anti-tangle rotating cylinder 1 from the cylinder.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the synchronous drive device is the power source for driving the anti-tangling rotating cylinder 1 to rotate. In a preferred embodiment, the synchronous drive device includes a drive motor 31. The drive motor 31 is mounted on the side of the motor support frame 33 via a motor mounting plate 32, and the motor support frame 33 is fixed to the frame or worktable. A small synchronous pulley 34 is fixedly connected to the output end of the drive motor 31. A large synchronous pulley 35 is coaxially fixed to the outer wall of the anti-tangling rotating cylinder 1. A synchronous belt 36 is tensioned between the small synchronous pulley 34 and the large synchronous pulley 35. When the drive motor 31 starts, its torque is transmitted to the large synchronous pulley 35 through the small synchronous pulley 34 and the synchronous belt 36, thereby driving the anti-tangling rotating cylinder 1 to rotate smoothly. In order to protect the drive motor 31 and the synchronous belt transmission part and improve operational safety, a cover plate 37 is fastened to the top of the motor mounting plate 32.

[0036] like Figure 1 and Figure 3As shown, the suction guide device is used to apply a continuous downward pulling force to the sock body during the knitting process and guide the sock body smoothly through. In a preferred embodiment, the suction guide device includes a suction box 41. The top of the suction box 41 is connected to the bottom of the anti-tangle rotating cylinder 1 via a second bearing 42. The second bearing 42 is mounted on the bottom of the anti-tangle rotating cylinder 1 via a second bearing seat 43. In this way, the suction box 41 can remain stationary, while the anti-tangle rotating cylinder 1 rotates relative to the suction box 41, avoiding the inconvenience caused by the suction box 41 rotating with it. The side of the suction box 41 is connected to the suction pipe and the discharge pipe via a negative pressure generator (not shown in the figure). When the negative pressure generator is working, negative pressure is generated in the suction box 41, the suction pipe, and the discharge pipe, thereby forming a downward suction force below the anti-tangle rotating cylinder 1, keeping the suspended sock body in a vertically tensioned state.

[0037] To ensure the stable installation of the entire device, the side of the sock suction box 41 is connected to the base plate 45 through the anti-tangling mechanism support frame 44, and the base plate 45 is fixed to the ground or the frame.

[0038] To facilitate real-time observation by operators of the socks moving within the suction box 41 and to promptly detect and address any abnormalities, an observation window is provided on the side of the suction box 41. The observation window is fitted with an openable and closable observation cover 46. Operators can view the condition of the socks inside through the transparent observation window.

[0039] When knitting begins or when handling unusual situations, it is necessary to be able to temporarily block the passage between the sock body and the suction guide device. Therefore, such as... Figure 3 and Figure 4 As shown, a sock-blocking cylinder 51 is provided at the bottom of the sock-absorbing box 41. The power output end of the sock-blocking cylinder 51 is connected to a rotating ring 52. The rotating ring 52 cooperates with the anti-tangling rotating cylinder 1. When the sock-blocking cylinder 51 is activated, its power output end drives the rotating ring 52 to move upward or downward. For example, during the knitting process, the rotating ring 52 is in a position where... Figure 3 The indicated rising position does not affect the passage of the sock body; when it is necessary to block it, the sock-blocking cylinder 51 drives the rotating ring 52 to descend to the desired position. Figure 4 The position shown aligns with the bottom edge of the anti-tangling rotating cylinder 1, closing or narrowing the sock body channel, thereby temporarily preventing the sock body from continuing to move downwards. To achieve flexible guidance during the lifting and lowering of the rotating ring 52 and to adapt to the rotational movement of the anti-tangling rotating cylinder 1, a third bearing 53 is provided between the power output end of the sock-blocking cylinder 51 and the rotating ring 52. Through the third bearing 53, the rotating ring 52, while rising and falling with the power output end of the cylinder, can remain stationary relative to the anti-tangling rotating cylinder 1 or undergo slight adaptive rotation, avoiding jamming.

[0040] The working principle of the present invention will be explained below with reference to the accompanying drawings:

[0041] Please see Figures 1 to 4 When the sock knitting machine begins knitting stockings, the cylinder rotates to knit the stocking body. Simultaneously, the electronic control system sends commands to the drive motor 31 based on a preset program or the real-time detected cylinder speed. The drive motor 31 starts, driving the anti-tangle rotating cylinder 1 to rotate via the small synchronous pulley 34, synchronous belt 36, and large synchronous pulley 35, precisely controlling its speed to match the cylinder speed. The knitted stocking body extends downwards from the cylinder, first entering the connecting tube 22 connected to the cylinder, and then entering the synchronously rotating anti-tangle rotating cylinder 1. Because the anti-tangle rotating cylinder 1 rotates synchronously with the cylinder, it provides rotational guidance for the stocking body suspended inside, allowing its upper part to rotate with the cylinder. Simultaneously, the negative pressure generator operates, generating negative pressure in the suction box 41, the suction pipe, and the discharge pipe, creating a downward suction force. This suction force acts on the lower part of the stocking body, keeping it in a vertically downward tensioned state and pulling it to rotate synchronously with the anti-tangle rotating cylinder 1. Through the rotational guide of the anti-tangling rotating cylinder 1 and the downward traction of the suction guide device, the upper and lower parts of the sock body achieve consistent rotation speed, effectively avoiding twisting, folding, and tangling caused by the lag in rotation of the lower half. Operators can monitor the sock body's status in real time through the observation window. When a sock begins knitting or an abnormality needs to be addressed, the sock-blocking cylinder 51 activates, driving the rotating ring 52 to descend, temporarily preventing the sock body from continuing to enter the suction pipe, facilitating subsequent sock changing or cleaning operations. The knitted sock is then picked up by the sewing device for the next sewing process.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] It should be noted that the components mentioned in the above embodiments are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0044] This invention has illustrated its principles and implementation methods using specific examples. The descriptions of these embodiments are merely illustrative of the method and its core ideas; furthermore, those skilled in the art will recognize that modifications may be made to the specific implementation methods and application scope based on the principles of this invention. Therefore, the content of this specification should not be construed as limiting the invention.
