Description

Technical Field

[0001] This invention relates to the field of knitting technology, and in particular to a knitting machine and its method of use. Background Technology

[0002] A knitting machine is a machine that weaves yarn into knitted fabric. It uses needles to bend the yarn into loops, which are then interlocked to form the knitted fabric. Knitting machines are categorized into weft knitting machines and warp knitting machines. Weft knitting machines feed yarn along the weft direction into working needles, which sequentially bend the yarn into loops and interlock them to form the knitted fabric. Fabrics produced by weft knitting machines are relatively soft and are often used in clothing. Warp knitting machines, on the other hand, feed one or more groups of parallel yarns radially into parallel working needles, simultaneously forming loops. This method has higher production efficiency and produces stiffer fabrics.

[0003] Knitting machines are classified into weft knitting machines and warp knitting machines according to their processing methods. Weft knitting machines include circular knitting machines and flat knitting machines. Circular knitting machines have needle beds that are connected end-to-end and are suitable for the production of seamless underwear and socks; flat knitting machines have needle beds that have both ends and are suitable for glove production.1 In addition, knitting machines can also be classified according to the number and type of needle beds, such as single-needle-bed knitting machines and double-needle-bed knitting machines, as well as flat knitting machines and circular knitting machines.

[0004] Knitting machines are widely used in the production of clothing, underwear, socks, gloves, and other products. For example, seamless underwear machines can produce shaped fabrics, reducing cutting and sewing, and making the products more comfortable and form-fitting; sock machines are used to produce flat, terry, and shoe sock products; and glove machines are suitable for knitting various types of gloves.

[0005] Circular knitting machines have seen rapid development due to their numerous loop-forming systems (referred to as yarn feed paths or loop-forming paths in enterprises, or simply paths), high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0006] Circular knitting machines are generally divided into two main categories: single-jersey and double-jersey. However, based on the types of fabrics they process, they can be further categorized as follows: Ordinary single-jersey circular knitting machines come in single-needle-track (one track), two-needle-track (two tracks), three-needle-track (three tracks), four-needle-track, and six-needle-track models. Currently, most knitting enterprises use four-needle-track single-jersey circular knitting machines. They utilize the organic arrangement and combination of needles and cams to knit various new fabrics. Single-jersey terry machines, also known as single-jersey towel machines, come in single-needle-track, double-needle-track, and four-needle-track models. They are further divided into overlock terry machines (where the terry yarn covers the ground yarn, meaning the terry yarn is visible on the front of the fabric while the ground yarn is covered) and reverse terry machines (where the ground yarn is on the reverse side of the fabric). They utilize sinkers and the arrangement and combination of yarns to knit and produce new fabrics. Large single-sided jacquard circular knitting machines, commonly known as computerized jacquard circular knitting machines, are so named because the pre-designed floppy disk is inserted into a computer, the program is input, and knitting production can begin; hence, they are also called "foolproof" circular knitting machines. These machines use computer programs to select needles for knitting, non-knitting, and tuck knitting. They are available in two-position (knitting and float knitting, knitting and tuck knitting) and three-position (one-way knitting, tuck knitting, and float knitting can be performed simultaneously). They are used to knit large-patterned fabrics and can change yarn colors, with options for four, five, six, and eight colors. They are suitable for large single-sided jacquard, jacquard terry, jacquard sweatshirt, and transfer knitting patterns.

[0007] Computerized circular knitting jacquard machines significantly shorten product design cycles, reduce product costs, and substantially improve product quality, thereby enhancing the economic and social benefits for enterprises and improving their competitiveness and responsiveness.

[0008] For example, application number 202320298684.2 discloses a large circular knitting machine, specifically relating to the field of large circular knitting machines. This application includes a large circular knitting machine body, on which a plurality of triangular seats are uniformly installed. The surface of the large circular knitting machine body is provided with an assembly structure, which includes a plurality of fixing blocks. The plurality of fixing blocks are fixedly connected to the surface of the large circular knitting machine body. Insert blocks are slidably connected to the surface of the fixing blocks. The side of the insert block away from the triangular seats is a sloping structure. By setting up the assembly structure, this application facilitates the disassembly and assembly of the triangular seats on the large circular knitting machine body, avoiding the need for workers to use wrenches or other tools to disassemble the triangular seats arranged in a circular array on the large circular knitting machine body one by one. This facilitates the disassembly and assembly of the triangular seats from the large circular knitting machine body by workers in a shorter time, thereby shortening the time for workers to perform regular maintenance on the large circular knitting machine body and maximizing the efficiency of maintenance on the large circular knitting machine body.

[0009] However, many current knitting machines suffer from problems such as needle circularity deviation, which causes fabric ridges. During disassembly and repair, quick positioning and repositioning are not possible. When slight precision deviations are caused by component deformation, repair is difficult. Yarn entanglement or breakage is common, leading to frequent downtime and affecting production efficiency. Traditional manual fabric unloading requires a large amount of manpower and is inefficient. The high labor costs and complexity of manual operation result in high production risks. Summary of the Invention

A method for using a knitting machine includes the following steps: S1. The wire passes through the grinding wheel and then enters the directional wheel; S2. After the yarn passes through the first set of directional wheels, it passes through the paraffin roller on the wax tray, then passes through the second set of directional wheels, and enters the portable yarn guiding mechanism. S3. The wire passes through the wire guide sleeve, winds around the wire guide disc, and enters the wire holder; S4. The thread is wound around the guide wire disc, enters the wire groove through the wire hole, hangs on the limiting hook, and then connects to the hook tip on the hook-shaped closing needle. When the hook tip on the next set of hook-shaped closing needles moves to the top, it continues to hook the thread, and repeats in turn. S5. During assembly, first use the fixed mounting holes for precision calibration. After the precision calibration is completed, drill positioning pin holes along the positioning pin holes and install positioning pins. When the precision is out of tolerance, install four screws in the four corner precision calibration holes and adjust the precision by screwing them in to different depths to press against the contact surface of the middle large plate. S6. When the rotating cylinder rotates, the hook-shaped closing needle located in the needle hanging groove rotates with the rotating cylinder. The guide rod is movably disposed in the needle guide groove, so that the hook-shaped closing needle travels along the needle guide groove path and moves up and down when rotating with the rotating cylinder. When moving downward, the tongue is hinged to the needle bar and is blocked and closed when descending, contacting the hook-shaped needle tip. When moving upward, the tongue moves away from the hook-shaped needle tip and performs a looping action. S7. During fabric unloading, when the fabric unloading support arm is at its pull-in limit, the drive roller is tangential to the fabric unloading roller shaft. The drive roller rotates via the roller motor, thereby causing the fabric unloading roller shaft to rotate within the U-shaped limiting groove under the action of the roller shaft limiting sleeve, thus achieving roll formation. When the predetermined length is reached, the drive roller stops rotating, and the cutting blade, driven by the rodless cylinder, completes transverse cutting of the fabric. After cutting, the displacement cylinder pushes the fabric unloading support shaft, causing the fabric unloading support arm to rotate along the fabric unloading support shaft. When the fabric reaches the second limiting mechanism position, the replacement receiving arm is located at the third limiting mechanism. The lower fabric roller enters the limiting contour groove from the U-shaped limiting groove. The rotating shaft cylinder drives the automatic replacement rotating shaft to rotate through the rotating shaft connecting rod, thereby driving the replacement receiving arm to rotate. The lower fabric roller is then moved downwards to prevent the fabric from being placed in the external transport vehicle and to return to its original position. When the fabric reaches the third limiting mechanism position, the stop shaft pushing cylinder pushes the stop shaft arm to rotate, so that the lower fabric roller smoothly enters the U-shaped limiting groove on the lower fabric support arm, completing the automatic fabric lowering and roller changing. Compared with the prior art, the beneficial effects of the present invention are: 1. By setting a self-positioning sinker, the running accuracy of the knitting machine is improved, effectively reducing the problem of fabric edge marks caused by the out-of-roundness of the knitting needles. By setting positioning pin holes, the stability of the assembly structure is improved, avoiding the movement of parts during rotation. At the same time, it can be quickly positioned and reset during disassembly and maintenance. Through the four-corner precision correction holes, when there is a slight out-of-tolerance precision due to the deformation of parts, it can be finely adjusted by screwing the four corners, which improves the convenience of maintenance.

[0013] 2. By setting up a portable yarn guide mechanism, its specific structure and design can effectively guide and control the movement of yarn on the knitting machine; through the design of the guide hole, guide groove and limit hook, the yarn is made to move along the preset path, avoiding yarn tangling or breakage, thereby ensuring the smooth progress of the knitting process; at the same time, it can reduce the problem of yarn tangling during the knitting process, reduce downtime and improve production efficiency.

[0014] 3. By setting a paraffin roller on the pre-treatment feeding mechanism, the silk thread passes around the paraffin roller, which improves the smoothness of the silk thread and can effectively avoid the problem of the silk thread breaking due to tangling caused by frizz.

[0015] 4. By setting the directional shaft, directional wheel, spring, and locking cap on the yarn feeding mechanism for pre-treatment of the yarn wrapping head, the tension of the yarn is optimized to ensure that the yarn maintains appropriate tension during the knitting process, and to avoid yarn breakage or fabric quality degradation caused by excessive or insufficient tension.

[0016] 5. By setting a grinding cloth wheel on the yarn feeding mechanism for pre-treatment of the yarn wrapping head, the cotton fibers suspended on the yarn can be detached from the yarn through friction in advance, effectively preventing the cotton fibers suspended on the yarn from entering the knitting and causing tangling.

[0017] 6. By installing an automatic fabric unloading mechanism, production efficiency can be improved. Traditional manual operation requires a large amount of manpower and is inefficient, while the automatic fabric unloading mechanism can quickly complete the fabric unloading process, significantly increasing production speed. The automatic fabric unloading mechanism can replace manual operation, reducing the demand for labor and thus lowering labor costs. Furthermore, automated operation reduces the complexity and labor intensity of manual operation, and lowers the safety risks associated with manual operation.

[0018] 7. By setting up a rodless cylinder, cutter holder, and cutter blade, the fabric cutting work can be completed quickly. By setting up a support rod to support both ends of the fabric being cut, and with the fabric tension, the cutting accuracy is effectively improved. This ensures the accuracy and consistency of the fabric being laid down, reduces errors and waste caused by human factors, and thus improves production quality.

[0019] 8. By setting the first limit mechanism, the second limit mechanism, and the third limit mechanism, the accuracy control of the automatic fabric transfer action position can be effectively improved, the integrity of the action and the degree of automation can be improved, the structure is simple and the functionality is strong.

A limiting hook 209 is provided at the end of the wire groove 208 away from the wire seat 206. In use, the wire is wound around the wire guide disc 214, enters the wire groove 208 through the wire hole 207, is hooked onto the limiting hook 209, and then connected to the hook-shaped needle tip 117 on the hook-shaped closing needle 115. When the hook-shaped needle tip 117 on the next set of hook-shaped closed needles 115 moves to the top, it continues to hook the yarn, repeating this process in sequence. By setting up a portable yarn guide mechanism, its specific structure and design can effectively guide and control the movement of the yarn on the knitting machine. Through the design of the guide hole, guide groove, and limit hook, the yarn is made to advance along a preset path, avoiding yarn tangling or breakage, thereby ensuring the smooth progress of the knitting process. At the same time, it can reduce the problem of yarn tangling during the knitting process, reduce downtime, and improve production efficiency.

[0025] In some embodiments, see Figure 10The pre-treatment feeding mechanism 3 includes a support rod 301, a pre-treatment disc 302, a disc thread hole 303, a position adjustment groove 304, a wax support disc 305, a paraffin roller 306, a directional support base 307, a directional shaft 308, a directional wheel 309, a spring 310, and a locking cap 311. Multiple sets of support rods 301 are evenly fixedly mounted on the feeding disc support 107. The pre-treatment disc 302 is fixedly mounted on the support rod 301. A disc thread hole 303 is fixedly mounted on one side of the pre-treatment disc 302, and a position adjustment groove 304 is opened on the top. A wax support disc 305 is fixedly mounted on the position adjustment groove 304 on the pre-treatment disc 302. The paraffin roller 306 is fixedly mounted on the pre-treatment disc 302. The directional support 307 is fixedly mounted on the support rod 301 and the directional support 305 is fixedly mounted on the support rod 301. Directional shafts 308 are fixedly mounted at both ends of the directional support 307. Springs 310 and directional wheels 309 are sequentially sleeved on the directional shafts 308 and locked by locking caps 311. In use, the yarn passes through the first set of directional wheels 309, then through the paraffin roller 306 on the wax support 305, then through the second set of directional wheels 309, and enters the portable yarn guide mechanism 2. By setting the paraffin roller on the yarn feeding mechanism, the yarn passes around the paraffin roller, improving the smoothness of the yarn and effectively avoiding yarn breakage caused by tangling due to frizz. By setting the directional shaft, directional wheel, spring, and locking cap on the yarn feeding mechanism, the yarn tension is optimized, ensuring that the yarn maintains appropriate tension during knitting and avoiding yarn breakage or fabric quality degradation due to excessive or insufficient tension.

[0026] In some embodiments, see Figure 10 The pre-treatment yarn feeding mechanism 3 also includes a hinged connecting rod 312 and a yarn grinding wheel 313. A hinged connecting rod 312 is fixedly installed on a set of directional shafts 308 away from the portable yarn guiding mechanism 2. A yarn grinding wheel 313 is fixedly installed on the hinged connecting rod 312 through a set of directional shafts 308, a spring 310, and a locking cap 311. In use, the yarn passes through the yarn grinding wheel 313 and then enters the directional wheel 309. By setting the yarn grinding wheel on the pre-treatment yarn feeding mechanism, cotton fibers suspended on the yarn can be pre-detached from the yarn through friction, effectively preventing tangling caused by cotton fibers suspended on the yarn entering the knitting process.

Two sets of rods 409 are arranged parallel to each other on both sides of the rodless cylinder 406 and fixedly mounted on the two sets of transverse left and right supports 405. The lower fabric support shaft 410 is movably mounted on the bottom side between the left support plate 401 and the right support plate 402. Two sets of lower fabric support arms 411 are arranged and fixedly mounted on both sides of the lower fabric support shaft 410. The lower fabric support arms 411 have U-shaped limiting grooves 412 at their ends. The lower fabric roller shaft 414 is movably mounted in the U-shaped limiting grooves 412 on the lower fabric support arms 411 after roller shaft limiting sleeves 415 are movably fitted at both ends. The displacement cylinder 413 is fixed inside the left support plate 401, and its output end is connected to the lower fabric support arm 411. A support shaft 410 is fixedly connected. An automatic replacement shaft 416 is movably disposed on the bottom side between the left support plate 401 and the right support plate 402, parallel to the lower support shaft 410. A shaft cylinder 418 is fixedly disposed on the outer side of the left support plate 401, and its output end is fixedly connected to the automatic replacement shaft 416 via a shaft connecting rod 417. Two sets of replacement receiving arms 419 are provided, fixedly disposed on both sides of the automatic replacement shaft 416.

Two sets of cylinders 422 are provided, respectively fixedly installed on the outer sides of the left support plate 401 and the right support plate 402, and their output ends are respectively fixedly connected to one end of the stop arm 421; two sets of the first limiting mechanism 423 are provided, respectively fixedly installed on the inner sides of the left support plate 401 and the right support plate 402, so as to limit the pull-in limit of the lower support arm 411; the second limiting mechanism 424 is fixedly installed on the inner sides of the left support plate 401 and the right support plate 402, so as to limit the push-out limit of the lower support arm 411; the third limiting mechanism 425 is fixedly installed on the inner sides of the left support plate 401 and the right support plate 402, so as to limit the pull-in limit of the replacement receiving arm 419;In use, when the lower fabric support arm 411 is at its pull-in limit, the drive roller 403 is tangential to the lower fabric roller shaft 414. The drive roller 403 is driven to rotate by the roller motor 404, thereby driving the lower fabric roller shaft 414 to rotate within the U-shaped limiting groove 412 under the action of the roller shaft limiting sleeve 415, thus achieving roll formation. When the predetermined length is reached, the drive roller 403 stops rotating, and the cutting blade 408 completes transverse cutting of the fabric under the drive of the rodless cylinder 406. After cutting, the displacement cylinder 413 pushes the lower fabric support rotating shaft 410 to drive the lower fabric support arm 411 to rotate along the lower fabric support rotating shaft 410. The lower fabric support arm 411 reaches the position of the second limiting mechanism 424. At this time, the replacement receiving arm 419 is located at the third limiting mechanism 424. At position 25, the lower fabric roller 414 enters the limiting contour groove 420 from the U-shaped limiting groove 412. The rotating shaft cylinder 418 drives the automatic changing rotating shaft 416 to rotate via the rotating shaft connecting rod 417, thereby driving the changing receiving arm 419 to rotate, lowering the fabric back into the external transport vehicle and returning the new lower fabric roller 414 to its position. When it reaches the position of the third limiting mechanism 425, the stop shaft pushing cylinder 422 pushes the stop shaft arm 421 to rotate, so that the lower fabric roller 414 smoothly enters the U-shaped limiting groove 412 on the lower fabric support arm 411, completing the automatic fabric lowering and roller changing. By setting up an automatic fabric lowering mechanism, production efficiency can be improved. Traditional manual operation requires a lot of manpower and is inefficient, while the automatic fabric lowering mechanism can quickly complete the fabric lowering work, significantly improving production speed. The automatic fabric lowering mechanism can replace manual operation, reduce the demand for labor, and thus reduce labor costs. Furthermore, automated operation reduces the complexity and labor intensity of manual operations, and lowers the safety risks associated with manual operation. By incorporating rodless cylinders, cutter holders, and cutter blades, the fabric cutting process can be completed quickly. Support rods at both ends of the fabric, combined with fabric tension, effectively improve cutting accuracy, ensuring the accuracy and consistency of fabric placement, reducing errors and waste caused by human factors, and thus improving production quality.

[0028] In some embodiments, see Figure 16 The first limiting mechanism 423 includes a support block 426, a limiting rod 427, and a set nut 428; the limiting rod 427 is fixedly mounted on the support block 426 and locked by the set nut 428; the second limiting mechanism 424 and the third limiting mechanism 425 are both composed of the support block 426, the limiting rod 427, and the set nut 428; by setting the first limiting mechanism, the second limiting mechanism, and the third limiting mechanism, the accuracy control of the automatic fabric lowering and conversion action position can be effectively improved, the integrity of the action and the degree of automation can be improved, the structure is simple, and the functionality is strong.

[0029] A method for using a knitting machine includes the following steps: S1. The silk thread is wound around the grinding cloth wheel 313 and then enters the directional wheel 309; S2. After the yarn passes through the first set of directional wheels 309, it passes through the paraffin roller 306 on the wax tray 305, then passes through the second set of directional wheels 309, and then enters the portable yarn guiding mechanism 2. S3. The wire passes through the wire guide sleeve 213, winds around the wire guide disc 214, and enters the wire seat 206; S4. The thread is wound around the guide wire disc 214, enters the wire groove 208 through the wire hole 207, hangs on the limiting hook 209, and then connects to the hook tip 117 on the hook-shaped closing needle 115. When the hook tip 117 on the next set of hook-shaped closing needles 115 moves to the top, it continues to hook the thread, and repeats in turn. S5. During assembly, first use the fixed mounting holes 112 to assemble and perform precision calibration. After the precision calibration is completed, drill positioning pin holes along the positioning pin holes 113 and install positioning pins. When the precision is out of tolerance, install four screws in the four corner precision calibration holes 114 and adjust the precision by screwing them in to different depths to press against the contact surface of the middle large plate 103. S6. When the rotating cylinder 108 rotates, the hook-shaped closing needle 115 located in the needle hanging groove 109 rotates with the rotating cylinder 108. The guide rod 119 is movably disposed in the needle guide groove 111, so that the hook-shaped closing needle 115 travels along the path of the needle guide groove 111 when rotating with the rotating cylinder 108, and moves up and down. When moving downward, the tongue 121 is hinged to the needle bar 116 and is blocked and closed when descending, contacting the hook-shaped needle tip 117. When moving upward, the tongue 121 moves away from the hook-shaped needle tip 117 and performs a looping action. S7. During fabric unloading, when the fabric unloading support arm 411 is at its pull-in limit, the drive roller 403 is tangential to the fabric unloading roller shaft 414. The drive roller 403 is driven to rotate by the roller motor 404, thereby driving the fabric unloading roller shaft 414 to rotate within the U-shaped limiting groove 412 under the action of the roller shaft limiting sleeve 415, thus achieving roll formation. When the predetermined length is reached, the drive roller 403 stops rotating, and the cutting blade 408 completes transverse cutting of the fabric under the drive of the rodless cylinder 406. After cutting, the displacement cylinder 413 pushes the fabric unloading support rotating shaft 410 to drive the fabric unloading support arm 411 to rotate along the fabric unloading support rotating shaft 410, and the fabric unloading support arm 411 reaches the predetermined length. When the second limiting mechanism 424 is in position, the replacement receiving arm 419 is located at the third limiting mechanism 425. The lower fabric roller 414 enters the limiting contour groove 420 from the U-shaped limiting groove 412. The rotating shaft cylinder 418 drives the automatic replacement rotating shaft 416 to rotate through the rotating shaft connecting rod 417, thereby driving the replacement receiving arm 419 to rotate. The lower fabric roller 414 is returned to its original position after the fabric is placed in the external transport vehicle. When it reaches the third limiting mechanism 425, the stop shaft pushing cylinder 422 pushes the stop shaft arm 421 to rotate, so that the lower fabric roller 414 smoothly enters the U-shaped limiting groove 412 on the lower fabric support arm 411, completing the automatic lower fabric roller replacement. Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.

When the predetermined length is reached, the drive roller (403) stops rotating, and the cutting blade (408) completes the transverse cutting of the fabric under the drive of the rodless cylinder (406). After the cutting is completed, the displacement cylinder (413) pushes the unloading support rotating shaft (410) to drive the unloading support arm (411) to rotate along the unloading support rotating shaft (410), and the unloading support arm (411) reaches the predetermined length. At the second limiting mechanism (424) position, the replacement receiving arm (419) is located at the third limiting mechanism (425). The lower fabric roller (414) enters the limiting contour groove (420) from the U-shaped limiting groove (412). The rotating shaft cylinder (418) drives the automatic replacement rotating shaft (416) to rotate through the rotating shaft connecting rod (417), thereby driving the replacement receiving arm (419) to rotate and lower the fabric back into the transport vehicle to prevent the new lower fabric roller (414) from being placed in the external transport vehicle. When it reaches the third limiting mechanism (425) position, the stop shaft pushing cylinder (422) pushes the stop shaft arm (421) to rotate so that the lower fabric roller (414) can smoothly enter the U-shaped limiting groove (412) on the lower fabric support arm (411) to complete the automatic lower fabric roller replacement.
