Description

Technical Field

[0001] This utility model relates to the field of knitting equipment technology, especially yarn feeders for knitting equipment, mainly yarn feeders for computerized flat knitting machines, specifically a yarn reciprocating motion mechanism, a yarn feeder, and a flat knitting machine. Background Technology

[0002] A flat knitting machine, also known as a horizontal knitting machine, is a type of machine used for knitting fabrics. It is widely used in the production of various knitted products such as sweaters, cashmere sweaters, scarves, and hats. It knits by moving the yarn across a horizontal knitting bed, allowing the yarn to form various knitted structures.

[0003] The working principle of a flat knitting machine is that the knitting head, equipped with a loop-forming mechanism, reciprocates on the needle bed, driving the latch needles to move up and down in the needle grooves to complete the knitting process. The knitting process of a flat knitting machine includes stages such as loop unwinding, yarn padding, yarn feeding, loop closing, loop forming, loop release, loop formation, and tensioning. These stages work together to enable the yarn to be knitted into a fabric.

[0004] There are many types of flat knitting machines. Based on the different transmission and control methods, they can be divided into manual flat knitting machines, semi-automatic mechanical flat knitting machines, fully automatic mechanical flat knitting machines, and computerized flat knitting machines. Based on their application, they can also be divided into glove knitting machines, hosiery knitting machines, collar knitting machines, ribbon knitting machines, and sweater knitting machines, among which sweater knitting machines are the most widely used.

[0005] The yarn feeder, also known as the yarn guide, is a device in a flat knitting machine used to draw yarn from the yarn passage of the spinning machine and deliver it to the loom or other processing equipment. It is usually made of metal and has a long cylindrical shape. One end is connected to the yarn passage of the spinning machine, and the other end leads out the yarn, which is then guided onto the loom by a yarn guide device for weaving. The function of the yarn feeder is to maintain the tension and stability of the yarn, ensuring its smooth delivery to the loom and guaranteeing the normal operation of the weaving process.

[0006] Yarn feeders typically use a main motor to rotate a drive wheel, which in turn feeds yarn through a driven wheel. Specifically, the yarn is fed by being clamped between the drive wheel (feeding wheel) and the driven wheel. During this process, friction occurs between the yarn and the drive and driven wheels, leading to wear and tear over time. In existing computerized flat knitting machines, the driven wheel is usually made of metal to withstand greater pressure and load, ensuring stability and preventing deformation during long-term operation. However, to better grip and feed the yarn, prevent slippage, and ensure stable and accurate feeding, non-metallic materials such as rubber are often used in the contact areas between the drive wheel (feeding wheel) and the yarn. Therefore, it is primarily the drive wheel (feeding wheel) that experiences wear during use. Since the yarn is usually fixed in a certain position during the yarn feeding process and does not move, the drive wheel often wears a groove in a certain position. Other parts of the drive wheel are intact because the yarn does not come into contact with them. This affects the service life of the drive wheel and increases the user's operating cost, which is not conducive to the promotion and application of the above-mentioned yarn feeder in the market.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0025] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] In existing technologies, since the yarn is usually fixed in a certain position during the yarn feeding process and does not move, the drive wheel often develops a groove in a certain position. Other positions of the drive wheel remain intact because the yarn does not come into contact with them. This affects the service life of the drive wheel and increases the user's operating costs, which is not conducive to the promotion and application of the aforementioned yarn feeder in the market.

[0028] Example: To solve the above-mentioned technical problems, such as Figures 1 to 8As shown, this embodiment of a yarn reciprocating motion mechanism is installed on the frame 1 of the yarn feeder and close to the drive wheel 2. The main purpose of this design is to prevent the yarn 8 from being located at the same position on the drive wheel 2, thereby avoiding wear caused by the yarn 8 at the same location on the drive wheel 2. This ensures the performance of the drive wheel 2 while extending its service life, reducing the frequency and cost of replacement for the user, and improving the user experience. Specifically, the yarn reciprocating motion mechanism 4 in this embodiment mainly consists of a mounting frame 4-1, a connecting seat 4-2, a connecting plate 4-3, and a drive assembly 4-4 for driving the mounting frame 4-1 to move along the axial direction of the drive wheel 2. The mounting frame 4-1 has a yarn passage hole 4-1-1 for the yarn 8 to pass through, and under the drive of the drive assembly 4-4, the mounting frame 4-1 can move left and right along its own length, thereby enabling the yarn 8 to reciprocate along the axial direction of the drive wheel 2.

[0029] The aforementioned mounting frame 4-1 includes a pair of oppositely arranged yarn-passing parts 4-1-2. Yarn-passing holes 4-1-1 are formed at the yarn-passing parts 4-1-2, and the central axes of the upper and lower yarn-passing holes 4-1-1 are aligned on the same straight line. That is, the pair of yarn-passing parts 4-1-2 are symmetrically arranged in the vertical direction. The yarn-passing holes 4-1-1 provide a channel for the yarn 8, allowing it to pass smoothly through the mounting frame 4-1 and move along the axial direction of the drive wheel 2 under the drive of the mounting frame 4-1, thus preventing the yarn 8 from being located at the same position on the drive wheel 2. The central axes of the upper and lower yarn-passing holes 4-1-1 are aligned on the same straight line to ensure the alignment and synchronization of the yarn 8 when passing through the mounting frame 4-1, reducing the offset and twisting of the yarn 8 during movement. The two mounting brackets with yarn guide sections 4-1-2 are connected as one unit via mounting bracket connecting section 4-1-3, which improves the structural strength and stability of the entire mounting bracket 4-1, ensuring that the mounting bracket 4-1 can reciprocate stably under the action of the drive assembly 4-4. A yarn guide ceramic eye 4-5 is installed at the aforementioned yarn guide hole 4-1-1. The yarn guide ceramic eye 4-5 is made of ceramic material to reduce friction of the yarn 8 when passing through the mounting bracket 4-1, thereby reducing wear on the yarn 8 and increasing its service life. The model of the yarn guide ceramic eye 4-5 can also be selected according to the specifications of the yarn 8, thus improving the versatility of the equipment.

[0030] To ensure the stability of the mounting frame 4-1 during movement and minimize its impact on the yarn 8, a connecting seat 4-6 is installed between the connecting plate 4-3 and the driving assembly 4-4 in this embodiment. The driving assembly 4-4 mainly consists of a drive motor 4-4-1 and a drive wheel 4-4-2. The output shaft 4-4-3 of the drive motor 4-4-1 is eccentrically connected to the drive wheel 4-4-2. The drive wheel 4-4-2 is installed inside the sliding frame 4-4-4. The sliding frame 4-4-4 is installed inside the base 4-4-6 via a guide shaft 4-4-5 and can slide along the axial direction of the guide shaft 4-4-5 under the drive of the drive motor 4-4-1. The connecting seat 4-6 connects the sliding frame 4-4-4 and the connecting plate 4-3. The connecting seat 4-6 acts as an intermediary, transmitting the power generated by the drive motor 4-4-1 to the connecting plate 4-3, thereby driving the entire yarn reciprocating motion mechanism. The output shaft 4-4-3 of the drive motor 4-4-1 is eccentrically connected to the drive wheel 4-4-2, converting the eccentric circumferential motion of the drive wheel 4-4-2 into the reciprocating linear motion of the sliding frame 4-4-4. This drives the connecting seat 4-6, the connecting plate 4-3, and the mounting bracket 4-1, thereby changing the position of the yarn 8 on the drive wheel 2. The sliding frame 4-4-4 is horizontally mounted within the base 4-4-6 via the guide shaft 4-4-5, allowing it to slide along the axial direction of the guide shaft 4-4-5 under the drive of the drive motor 4-4-1, ensuring smooth and accurate movement. The guide shaft 4-4-5 also reduces friction in the sliding frame 4-4-4 during sliding, improving smoothness and reducing energy consumption. The connecting seat 4-6 connects the sliding frame 4-4-4 and the connecting plate 4-3, improving the structural stability of the entire yarn reciprocating motion mechanism and ensuring stability during high-speed movement.

[0031] To further improve the stability of the sliding frame 4-4-4 during movement, two guide shafts 4-4-5 are provided. These two guide shafts 4-4-5 are arranged in parallel and both pass through the base 4-4-6. The guide shafts 4-4-5 located outside the base 4-4-6 are fixed by a hoop. The two parallel guide shafts 4-4-5 provide more stable guidance, reducing the offset and swaying of the sliding frame 4-4-4 during movement, distributing the load, improving the overall load-bearing capacity of the mechanism, and reducing wear on individual guide shafts 4-4-5. The sliding frame 4-4-4 has a cuboid structure, and a slot 4-4-4-1 for mounting the drive wheel 4-4-2 is provided at its center. The drive wheel 4-4-2 is embedded in the slot 4-4-4-1 so that the sliding frame 4-4-4 can move synchronously with the drive wheel 4-4-2, reducing energy consumption.

[0032] To facilitate the installation of the drive assembly 4-4 within the frame 1, the drive assembly 4-4 in this embodiment further includes a base pad 4-4-7. The base pad 4-4-7 has a hollow open structure. The drive motor 4-4-1 is installed inside the base pad 4-4-7. The base 4-4-6 is installed at the opening of the base pad 4-4-7. The output shaft 4-4-3 passes through the output hole at the center of the base 4-4-6 and is connected to the drive wheel 4-4-2.

[0033] The aforementioned connector 4-2 has a mounting groove 4-2-1 that matches the width of the mounting bracket connection part 4-1-3. That is, the connector 4-2 is snapped into the mounting bracket connection part 4-1-3 and then fixed by fastening screws or other connecting parts to ensure the reliability of the connection between the two.

[0034] The yarn reciprocating motion mechanism in the above embodiments can be applied to, but is not limited to, a yarn feeder. The yarn feeder includes the yarn reciprocating motion mechanism, as well as a frame 1, a driving wheel 2, a driven wheel 3, an auxiliary yarn guide wheel 5, and a buffer rod 6 with a yarn outlet 7. The frame 1 has a yarn inlet 1-1. The yarn 8 passes through the yarn inlet 1-1 at the top of the frame 1 in sequence, passing over the driving wheel 2 and the driven wheel 3. The yarn reciprocating motion mechanism 4 repeatedly adjusts the position of the yarn 8 on the driving wheel 2, and then passes through the auxiliary yarn guide wheel 5 and the yarn outlet 7 in sequence to achieve the conveying of the yarn 8. By applying the yarn reciprocating motion mechanism 4, the yarn feeder also has the advantage of preventing the yarn 8 from wearing down the same position of the driving wheel 2 for a long time, thereby reducing the user's use and maintenance costs, improving the user experience, and facilitating the promotion and application of the yarn feeder on flat knitting machines.

[0035] The aforementioned yarn feeder can be applied to, but is not limited to, flat knitting machines. By applying the aforementioned yarn feeder, it also has the advantages of reducing user operating and maintenance costs and improving user experience.

[0036] This embodiment presents a yarn reciprocating motion mechanism with an ingenious structure. Mounted on the frame 1 of the yarn feeder, close to the drive wheel 2 (yarn feeding wheel), it comprises a mounting frame 4-1, a connecting seat 4-2, a connecting plate 4-3, and a drive assembly 4-4. The drive assembly 4-4 drives the connecting plate 4-3, which in turn passes through the yarn 8 on the mounting frame 4-1 and moves repeatedly or reciprocally along the circumferential direction of the drive wheel 2. This prevents the yarn 8 from remaining in the same position on the drive wheel 2, thus avoiding wear caused by the yarn 8 at the same location on the drive wheel 2. This ensures the performance of the drive wheel 2 while extending its service life, reducing the frequency and cost of replacement for users, improving the user experience, and facilitating the promotion and application of the aforementioned yarn reciprocating motion mechanism in yarn feeders.
