Description

Technical Field

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

[0002] Flat knitting machine, full name flat knitting machine, is a machine used to knit knitted products, widely used in the production of various knitted products such as wool sweaters, cashmere sweaters, scarves, hats, etc. It knits through a horizontal knitting needle bed, so that the yarn can form various knitted structures.

[0003] The working principle of the flat knitting machine is that the machine head equipped with the loop forming mechanism moves back and forth on the needle bed, driving the latch needle to move up and down in the needle groove to complete the knitting. The knitting process of the flat knitting machine includes the stages of unwinding, padding, bringing yarn, closing, looping, unlooping, looping and pulling. These stages work together to enable the yarn to be woven into knitted fabrics.

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

[0005] The yarn feeder is a device in a flat knitting machine that is used to lead the yarn from the yarn channel of the spinning machine and send it to the loom or other process equipment. It is usually made of metal and has a long cylindrical shape. One end is connected to the yarn channel of the spinning machine, and the other end leads the yarn and guides the yarn to the loom for weaving through the yarn guide device. The function of the yarn feeder is to maintain the tension and stability of the yarn so that the yarn can be smoothly delivered to the loom to ensure the normal progress of the weaving process.

[0006] The yarn feeder usually uses the main motor to rotate the driving wheel and the driven wheel to transport the yarn. At the same time, the encoder installed on the main motor is used to calculate the number of turns of the driving wheel to obtain the length of the transported yarn; the yarn transported by the driving wheel passes through the tension adjustment device and finally enters the computer flat knitting machine and other knitting equipment for weaving. Since the above structure is provided with a tension adjustment device, it can basically ensure that the tension of the yarn (that is, the yarn transported to the computer flat knitting machine and other knitting equipment) is consistent. However, in actual use, because the knitting equipment uses the yarn at times, it will slow down or stop or reverse suddenly when transporting the yarn (the yarn is quickly retracted), and the problem of inaccurate length of the transported yarn often occurs. The amount of recovered yarn varies and they are often piled together. Since these yarns are not stretched tight (although many knitting equipment have antenna racks to pass the yarn, and swing arms to recover the yarn by swinging at an angle, the swing range needs to be adjusted manually, and it is fixed after adjustment and cannot be changed at any time according to actual conditions. In addition, the amount of 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

[0021] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships 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.

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] 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, and in order to save space and reduce difficulty, the yarn feeder 2 can be directly installed on the 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.

[0025] In order to stably convey the yarn 3-1 and ensure the accuracy of the length of the yarn 3-1 during the conveying process, thereby reducing the probability of the yarn 3-1 becoming loose, the knitting quality of the knitting equipment is ensured. 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 shell one 2-1-1 can be detachably installed on the 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 main body bracket 2-2 is installed in the shell 2-1, and the active yarn feeding assembly is installed on the main body bracket 2-2.

[0026] The active yarn feeding assembly in this embodiment includes a yarn feeding active wheel 2-5, a yarn feeding driven wheel 2-6, and an active wheel driving member 2-14 for driving the yarn feeding active wheel 2-5 to move. The active wheel driving member 2-14 is a motor, which has the advantages of high efficiency, high torque, high responsiveness, no pollution and low noise, easy control and integration, and renewable energy utilization. The yarn feeding active wheel 2-5 is arranged in coordination with the yarn feeding driven wheel 2-6, that is, the yarn feeding active wheel 2-5 is driven by the active wheel driving member 2-14, and then the yarn feeding driven wheel 2-6 is driven to rotate by the yarn feeding active wheel 2-5, thereby realizing the delivery of the yarn 3-1.

[0027] In order to reduce the probability of yarn 3-1 breaking during the conveying process, in this embodiment, an anti-wear ring 2-11 is provided on the outer cover of the yarn feeding active wheel 2-5. The anti-wear ring 2-11 is made of rubber material. Rubber 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 to reduce the direct contact between the yarn feeding active wheel 2-5 and the yarn 3-1, thereby reducing the wear and damage of the yarn 3-1 caused by the yarn feeding active wheel 2-5. The yarn feeding active wheel 2-5 includes an active meshing part 2-5-1 and an active yarn feeding part 2-5-2, and the yarn feeding driven wheel 2-6 includes a driven meshing part 2-6-1 and a driven yarn feeding part 2-6-2. The active meshing part 2-5-1 and the driven meshing part 2-6-1 are meshed with each other; the anti-wear ring 2-11 is sleeved outside the active yarn feeding part 2-5-2. In order to prevent the yarn 3-1 from passing through the active meshing part 2-5-1, a retaining ring 2-5-3 is provided between the active meshing part 2-5-1 and the active yarn feeding part 2-5-2. The retaining ring 2-5-3 can also enable the yarn 3-1 to be transported along a predetermined path and speed, thereby maintaining the stable transportation of the yarn 3-1, avoiding the accumulation and disorder of the yarn 3-1, and improving the transportation efficiency and quality. Similarly, in order to further enable the yarn 3-1 to be transported along a predetermined path and speed, a yarn retaining plate 2-6-3 is provided at the passive yarn feeding part 2-6-2. The yarn retaining plate 2-6-3 can also adjust the tension of the yarn 3-1 by contacting with the yarn 3-1, thereby ensuring the yarn feeding effect.

[0028] The auxiliary yarn feeding assembly in this embodiment is mainly composed of an auxiliary yarn wheel 2-8, an adjusting rocker 2-7 and a rocker driving member 2-12 for driving the adjusting rocker 2-7 to swing. The auxiliary yarn wheel 2-8 is arranged close to the adjusting rocker 2-7. One end of the adjusting rocker 2-7 is installed at the output end of the rocker driving member 2-12, and the other end is provided with a yarn guide ring 2-9 for the yarn 3-1 to pass through. The rocker driving member 2-12 is a voice coil motor, which is an electromagnetic vibrator consisting of a voice coil and a magnetic field. When the voice coil is energized, the current will generate a magnetic field around the voice coil, and the interaction with the magnetic field will cause the voice coil to be affected by electromagnetic force, thereby generating mechanical vibration, and then driving the adjusting rocker 2-7 to change the position of the adjusting rocker 2-7, thereby changing the tension of the yarn 3-1. Specifically, the above-mentioned adjustment swing rod 2-7 includes a swing rod mounting portion 2-7-1, a swing rod body 2-7-2 and a yarn ring mounting portion 2-7-3. The above-mentioned swing rod mounting portion 2-7-1 and the above-mentioned yarn ring mounting portion 2-7-3 are formed at both ends of the above-mentioned swing rod body 2-7-2. The swing rod mounting portion 2-7-1 is used to be installed at the output end of the swing rod driving member 2-12, and the yarn ring mounting portion 2-7-3 is used for installing the yarn guide ring 2-9. The swing rod body 2-7-2 is arranged in a rod shape as a whole.

[0029] In order to ensure the yarn feeding effect, a yarn feeding ring 2-4 for the yarn 3-1 to pass through is installed on the housing 2-1 located above the active yarn feeding assembly. In order to facilitate the installation of the yarn feeding ring 2-4, a mounting support plate 2-13 is installed on the housing 2-1, and the yarn feeding ring 2-4 is then installed on the mounting support plate 2-13, and the mounting support plate 2-13 is provided with a through hole for the yarn 3-1 to pass through. In order to further ensure the yarn feeding effect, a yarn passing ring 2-10 is installed on the main body bracket 2-2 located below the yarn feeding driven wheel 2-6.

[0030] 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 on the shell 2-1, and the multiple layers of the active yarn feeding assembly and the multiple layers of the auxiliary yarn feeding assembly are arranged at intervals. Specifically, the active yarn feeding assembly and the auxiliary yarn feeding assembly are designed as two layers, a total of four layers, that is, 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: the yarn 3-1 enters from the yarn feeding ring 2-4 located at the top, and is output from the yarn guide ring 2-9 on the adjusting swing rod 2-7 in the auxiliary yarn feeding assembly located on the fourth layer. The swing rod driving member 2-12 located on the fourth layer, that is, the voice coil motor, adjusts the adjusting swing rod 2-7 at any time, so that the adjusting swing rod 2-7 swings up and down, so as to stabilize the tension of the output yarn 3-1 within a required range. The circumferential surfaces of the yarn feeding active wheel 2-5 and the yarn feeding driven wheel 2-6 located on the third layer are tightly matched to compress the yarn 3-1 under the action of the adjusting rocker 2-7 located on the fourth layer, so as to transport the yarn 3-1. In this process, the yarn feeding active wheel 2-5 and the yarn feeding driven wheel 2-6 are meshed and matched, thereby ensuring that the yarn feeding active wheel 2-5 and the yarn feeding driven wheel 2-6 will not slip. The anti-wear ring 2-11 on the yarn feeding active wheel 2-5 increases the friction with the yarn 3-1 to ensure that the yarn 3-1 will not slip. The motor located on the third layer is a servo motor with a magnetic braid at the tail, and the length of the transported yarn can be obtained by recording the number of revolutions of the motor. The motor, the yarn feeding active wheel 2-5 and the yarn feeding driven wheel 2-6 located on the first layer have the same principle as the motor, the yarn feeding active wheel 2-5 and the yarn feeding driven wheel 2-6 located on the third layer. The stability of the yarn tension entering the yarn passing ring 2-10 located on the third layer can be ensured by controlling the adjusting swing rod 2-7 through the voice coil motor. When the yarn 3-1 needs to be recovered, the motor located on the first layer drives the yarn feeding active wheel 2-5 and the yarn feeding driven wheel 2-6 to respond quickly, thereby ensuring the accuracy of the yarn feeding length and the stability during the yarn output process.

[0031] In order to simplify the structure of the flat knitting machine, the main body of the frame 1 in this embodiment is composed of two vertical columns 1-1 parallel to each other. The vertical columns 1-1 are arranged in an L shape, so as to facilitate the subsequent installation of the antenna platform 5 on the top of the vertical columns 1-1. The antenna platform 5 is located above the placement platform 4 and a thread take-up frame 6 capable of adjusting the tension of the yarn 3-1 is also installed on the antenna platform 5. The thread take-up frame 6 can be used alone or in conjunction with the yarn feeder 2. The purpose of being arranged here is mainly 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 for supporting the yarn 3-1 is installed inside the thread take-up mounting frame 6-1, and 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 are installed outside the thread take-up frame 6, and the thread take-up adjustment member 6-2 is a manual adjustment wheel, through which the angle of the thread take-up frame 6 can be manually adjusted to tighten and loosen the yarn 3-1.

[0032] 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 platform 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.
