Description

Technical Field

[0001] The utility model relates to the technical field of knitting equipment, in particular to a flat knitting machine. Background Art

[0002] A flat knitting machine, also known as a flat knitting machine, is a machine used to knit knitwear. It is widely used in the production of various knitted products such as wool sweaters, cashmere sweaters, scarves, hats, etc. It knits by knitting across the needle bed, allowing the yarn to be formed into various knitted structures.

[0003] The working principle of a flat knitting machine is that a machine head equipped with a loop-forming mechanism reciprocates across a needle bed, driving the latch needles up and down in the needle grooves to complete the knitting process. The knitting process includes stages such as unwinding, laying, bringing in, closing, looping, casting off, looping, and drawing. These stages work together to weave the yarn into a knitted fabric.

[0004] There are many types of flat knitting machines. Based on their drive and control methods, they can be categorized as manual, semi-automatic, fully automatic, and computerized. Based on their intended use, they can be further divided into glove knitting machines, hosiery knitting machines, collar knitting machines, ribbon knitting machines, and sweater knitting machines, with sweater knitting machines being the most widely used.

[0005] A yarn feeder, also known as a yarn conveyor, is a device in a flat knitting machine that draws yarn from the spinning machine's yarn channel and delivers it to a loom or other process equipment. It is typically made of metal and has a long, cylindrical shape. One end connects to the spinning machine's yarn channel, while the other end draws the yarn and guides it to the loom via a yarn guide for weaving. The function of the yarn feeder is to maintain yarn tension and stability, ensuring smooth yarn delivery to the loom and proper weaving.

[0006] A yarn feeder typically uses a main motor to rotate a driving wheel, assisted by a driven wheel, to feed the yarn. An encoder mounted on the main motor counts the number of rotations of the driving wheel, providing information on the length of the yarn being fed. The yarn fed by the driving wheel then passes through a tension adjustment device before entering a knitting machine, such as a computerized flat knitting machine, for weaving. The tension adjustment device in this structure generally ensures consistent tension on the yarn output (i.e., the yarn delivered to the computerized flat knitting machine, etc.). However, in practice, the yarn feeder often experiences intermittent speed changes, and sudden slowdowns, stops, or reversals (rapid yarn retraction) during yarn feeding often lead to inaccurate yarn lengths. The amount of recovered yarn varies and they are often piled together. Since these yarns are not taut (although many knitting equipment have antenna racks to pass the yarn, and there are also swing arms to recycle the yarn by swinging at a certain angle, the swing range needs to be adjusted manually. After adjustment, it is fixed and cannot be changed at any time according to actual conditions. In addition, the recovered yarn is also limited, and a little more will not work), it will affect the next yarn feeding, which will lead to inaccurate calculation of the length of the conveyed yarn, affecting the knitting quality of the knitting equipment, and then affecting the user experience, which is not conducive to the promotion and application of the above-mentioned flat knitting machines in the market.

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0032] Example: Figures 1 to 9 As shown, a flat knitting machine is mainly composed of a frame 1, a yarn feeder 2 and a placement platform 4. Multiple yarn bobbins 3 can be placed on the placement platform 4. In order to save space and reduce difficulty, the above-mentioned yarn feeder 2 can be directly installed on the above-mentioned placement platform 4. The specific installation method is not limited here, and it is mainly sufficient to ensure the stability of the yarn feeder 2.

[0033] In order to stably deliver the yarn 3-1 and ensure the accuracy of the length of the yarn 3-1 during the delivery process, thereby reducing the probability of the yarn 3-1 becoming loose, the knitting quality of the knitting equipment is guaranteed. The yarn feeder 2 in this embodiment is mainly composed of a shell 2-1, a main body bracket 2-2, a multi-layer active yarn feeding assembly and a multi-layer auxiliary yarn feeding assembly. In order to facilitate disassembly, maintenance and overhaul, the shell 2-1 in this embodiment is a split structure, that is, the shell 2-1 can be split into shell one 2-1-1 and shell two 2-1-2, and the above-mentioned shell one 2-1-1 can be detachably installed on the above-mentioned shell two 2-1-2 through other connecting parts such as bolts and screws. In order to ensure the stability of the yarn feeder during the yarn feeding process, and at the same time ensure the service life of each component and reduce the user's use cost, the above-mentioned main body bracket 2-2 is installed in the above-mentioned shell 2-1, and the above-mentioned active yarn feeding assembly is installed on the above-mentioned main body bracket 2-2.

[0034] The active yarn feeding assembly in this embodiment includes a yarn feeding driving wheel 2-5, a yarn feeding driven wheel 2-6, and a driving wheel driver 2-14 for driving the yarn feeding driving wheel 2-5. The driving wheel driver 2-14 is a motor having advantages such as high efficiency, high torque, high responsiveness, no pollution, low noise, easy control and integration, and renewable energy utilization. The yarn feeding driving wheel 2-5 and the yarn feeding driven wheel 2-6 are arranged in coordination, that is, the driving wheel driver 2-14 drives the yarn feeding driving wheel 2-5, and the yarn feeding driven wheel 2-6 is then driven by the yarn feeding driving wheel 2-5 to rotate, thereby achieving the conveyance of the yarn 3-1.

[0035] In order to reduce the probability of yarn 3-1 breaking during transport, in this embodiment, an anti-wear ring 2-11 is provided on the outer surface of the yarn feeding active wheel 2-5. The anti-wear ring 2-11 is made of rubber material, which has good wear resistance and can reduce the damage to the yarn 3-1 caused by friction and wear. As a protective component, the anti-wear ring 2-11 can form a rubber protective layer on the contact surface, reducing direct contact between the yarn feeding active wheel 2-5 and the yarn 3-1, thereby reducing the wear and damage caused by the yarn feeding active wheel 2-5 to the yarn 3-1. The yarn feeding active wheel 2-5 includes an active meshing portion 2-5-1 and an active yarn feeding portion 2-5-2, and the yarn feeding driven wheel 2-6 includes a driven meshing portion 2-6-1 and a driven yarn feeding portion 2-6-2. The active meshing portion 2-5-1 and the driven meshing portion 2-6-1 mesh with each other; the anti-wear ring 2-11 is sleeved on the outer surface of the active yarn feeding portion 2-5-2. In order to prevent the yarn 3-1 from passing through the active meshing portion 2-5-1, a retaining ring 2-5-3 is provided between the active meshing portion 2-5-1 and the active yarn feeding portion 2-5-2. The retaining ring 2-5-3 can also enable the yarn 3-1 to be fed along a predetermined path and speed, thereby maintaining stable feeding of the yarn 3-1, preventing accumulation and disorder of the yarn 3-1, and improving feeding efficiency and quality. Similarly, in order to further enable the yarn 3-1 to be fed along a predetermined path and speed, a yarn retaining plate 2-6-3 is provided at the driven yarn feeding portion 2-6-2. The yarn retaining plate 2-6-3 can also adjust the tension of the yarn 3-1 by contacting the yarn 3-1, thereby ensuring the yarn feeding effect.

[0036] The auxiliary yarn feeding assembly in this embodiment primarily comprises an auxiliary yarn feeding wheel 2-8, an adjusting rocker 2-7, and a rocker driver 2-12 that drives the adjusting rocker 2-7. The auxiliary yarn feeding wheel 2-8 is positioned adjacent to the adjusting rocker 2-7. One end of the adjusting rocker 2-7 is mounted on the output end of the rocker driver 2-12, while the other end is provided with a yarn guide ring 2-9 through which the yarn 3-1 passes. The rocker driver 2-12 is a voice coil motor, an electromagnetic vibrator consisting of a voice coil and a magnetic field. When current is applied to the voice coil, the current generates a magnetic field around the voice coil. The interaction with the magnetic field causes the voice coil to be subjected to electromagnetic force, generating mechanical vibrations. This in turn drives the adjusting rocker 2-7, causing it to change its position, thereby changing the tension of the yarn 3-1. Specifically, the adjusting rocker 2-7 includes a rocker mounting portion 2-7-1, a rocker body 2-7-2, and a yarn ring mounting portion 2-7-3. The rocker mounting portion 2-7-1 and the yarn ring mounting portion 2-7-3 are formed at both ends of the rocker body 2-7-2. The rocker mounting portion 2-7-1 is used to be mounted on the output end of the rocker drive member 2-12, and the yarn ring mounting portion 2-7-3 is used to mount the yarn guide ring 2-9. The rocker body 2-7-2 is generally rod-shaped.

[0037] To ensure efficient yarn feeding, a yarn feed ring 2-4 is mounted on the housing 2-1, located above the active yarn feed assembly, through which the yarn 3-1 passes. To facilitate installation of the yarn feed ring 2-4, a mounting support plate 2-13 is mounted on the housing 2-1. The mounting support plate 2-13 has a through hole for the yarn 3-1 to pass through. To further ensure efficient yarn feeding, a yarn passing ring 2-10 is mounted on the main frame 2-2, located below the driven yarn feed wheel 2-6.

[0038] In order to ensure the tension of the yarn 3-1 during the conveying process, in this embodiment, the auxiliary yarn feeding assembly is installed in the housing 2-1, and multiple layers of the active yarn feeding assembly and multiple layers of the auxiliary yarn feeding assembly are spaced apart. Specifically, the active yarn feeding assembly and the auxiliary yarn feeding assembly are both designed to be two layers, totaling four layers, i.e., the first layer is the active yarn feeding assembly, the second layer is the auxiliary yarn feeding assembly, the third layer is the active yarn feeding assembly, and the fourth layer is the auxiliary yarn feeding assembly. Specifically, the conveying process of the yarn 3-1 is as follows: the yarn 3-1 enters from the yarn feeding ring 2-4 at the top and is output from the yarn guide ring 2-9 on the adjustment rocker 2-7 in the auxiliary yarn feeding assembly located on the fourth layer. The rocker driving member 2-12, i.e., the voice coil motor located on the fourth layer, adjusts the adjustment rocker 2-7 at any time, causing the adjustment rocker 2-7 to swing up and down, thereby stabilizing the tension of the output yarn 3-1 within a required range. The circumferential surfaces of the yarn feeding drive wheel 2-5 and the yarn feeding driven wheel 2-6 on the third layer work closely together to compress the yarn 3-1 under the action of the adjusting rocker 2-7 on the fourth layer, thereby conveying the yarn 3-1. During this process, the yarn feeding drive wheel 2-5 and the yarn feeding driven wheel 2-6 mesh and cooperate, ensuring that the yarn feeding drive wheel 2-5 and the yarn feeding driven wheel 2-6 do not slip. The anti-friction ring 2-11 on the yarn feeding drive wheel 2-5 increases the friction with the yarn 3-1, ensuring that the yarn 3-1 does not slip. The motor on the third layer is a servo motor with a magnetic braid at the tail. The length of the yarn conveyed is calculated by recording the number of motor revolutions. The motor, yarn feed drive wheel 2-5, and yarn feed driven wheel 2-6 on the first layer operate in the same manner as those on the third layer. The voice coil motor controls and adjusts the rocker 2-7, ensuring stable tension in the yarn entering the yarn feed ring 2-10 on the third layer. When yarn 3-1 needs to be reeled in, the motor on the first layer drives the yarn feed drive wheel 2-5 and yarn feed driven wheel 2-6, enabling a quick response, ensuring accurate yarn delivery and stable yarn delivery.

[0039] To simplify the knitting machine structure, the main body of the frame 1 in this embodiment consists of two parallel upright posts 1-1. These posts 1-1 are arranged in an L-shape to facilitate the subsequent installation of an antenna platform 5 on top of these posts 1-1. The antenna platform 5 is located above the placement platform 4 and is also mounted with a thread take-up stand 6 capable of adjusting the tension of the yarn 3-1. The thread take-up stand 6 can be used independently or in conjunction with the yarn feeder 2. Its primary purpose is to assist the yarn feeder 2 in feeding the yarn. Specifically, the thread take-up frame 6 includes a thread take-up mounting frame 6-1, which is arranged in an open structure and a thread take-up support column 6-4 supporting the yarn 3-1 is installed inside the thread take-up mounting frame 6-1. The thread take-up frame 6 is externally installed with a hook-shaped thread take-up hook 6-3 and a thread take-up adjustment member 6-2 for adjusting the thread take-up hook 6-3. The thread take-up adjustment member 6-2 is a manual adjustment wheel, and the angle of the thread take-up frame 6 can be manually adjusted by the manual adjustment wheel to tighten and loosen the yarn 3-1.

[0040] In the flat knitting machine in this embodiment, the order in which the yarn 3-1 enters is: the yarn 3-1 on the yarn bobbin 3 goes to the thread take-up frame 6 on the antenna station 5, and then is transported from the thread take-up frame 6 to the yarn feeder 2, and then the yarn 3-1 is woven, etc. In this process, since the yarn feeder 2 is a multi-layer structure, the yarn feeder 2 can effectively ensure the stability of the yarn output and the accuracy of the yarn output length by setting an active yarn feeding component and an auxiliary yarn feeding component, thereby ensuring the knitting quality of the knitting equipment, enhancing the user experience, and being conducive to the promotion and application of the above-mentioned yarn feeder in the field of knitting equipment technology.

[0041] The above description of the disclosed embodiments will enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
