AI Technical Summary
During operation, traditional warp knitting machines have a large oscillation range of the guide bars, resulting in large fluctuations in the tension of the knitting yarn, which affects the improvement of machine speed and the selection of yarn types.
The same cam controls the up-and-down movement of the front and rear needle beds. The oscillation of the guide bar and the needle bed is controlled by the same cam. The tongue needle moves in opposite directions with the guide bar, reducing the oscillation stroke of the guide bar and stabilizing the yarn tension.
By reducing the oscillation stroke of the comb bar and stabilizing the yarn tension, the machine speed is increased and the use of lower strength yarns is allowed, thus improving the weaving quality.

[0002] A warp knitting machine is a machine that uses one or more sets of parallel yarns to simultaneously form loops on all the working needles of the machine in the warp direction to create a knitted fabric. This knitted fabric is called a warp-knitted fabric, and the machine that performs this warp knitting is called a warp knitting machine.
[0003] The working principle of a warp knitting machine mainly involves steps such as yarn feeding, loop formation, and drafting. The yarn is fed into the knitting zone through guide needles and forms loops through the cooperation of loop-forming components such as needles and sinkers. These loops connect to each other according to a specific weave pattern, ultimately forming a knitted fabric. During the loop formation process, the guide bar traversing mechanism is responsible for moving the guide bars laterally according to the requirements of the knitted fabric structure, so as to knit a fabric with a specific weave structure.

[0038] This utility model embodiment provides a warp knitting machine for weaving ribbons, including a main unit and a main unit crossbeam 103 disposed above the main unit. The main unit includes a base and a left wall plate 101 and a right wall plate 102. A rear swing mechanism, a needle bed mechanism, a cam mechanism, and a sinking mechanism are installed between the left and right wall plates 102. A warp beam 707 frame is disposed above the crossbeam 103. The cam mechanism includes a main shaft 211, on which at least two rear swing cams 212 and at least two needle bed cams 313 are sleeved. The rear swing mechanism includes a plurality of yarn guide needles 202. The structure includes an upper swing shaft 203, a middle swing shaft 206, a front swing shaft 210, and a rear swing shaft 208. The guide needle 202 is fixedly connected to the upper swing shaft 203 via a rocker arm 201. The upper swing shaft 203 is fitted with upper swing arms 204 at both ends, and the middle swing shaft 206 is fitted with lower swing arms 207 at both ends. The upper swing arms 204 and the lower swing arms 207 are hinged together via a rear comb upper connecting rod 205. The lower swing arms 207 are hinged to a rear swing cam 212 via a rear comb lower connecting rod 209. The rear swing cam 212 is fitted onto both ends of the main shaft 211.
[0039] The rear swing shaft 208 is fitted with second cam swing arms 307 on both sides. The second cam swing arms 307 are hinged to the rear swing cam 212. The upper swing arm 204 and the lower swing arm 207 of the comb are provided with a number of adjustment holes.
[0040] The second cam arm 307, mounted on the rear swing shaft 208, is driven to swing by the main shaft 211 and two rear swing cams 212 mounted on the main shaft 211.
[0041] The second cam swing arm 307 drives the comb lower swing arm 207, which is hinged to the middle swing shaft 206, to swing through the rear comb lower connecting rod 209. The comb lower swing arm 207 is provided with several adjustment holes. By adjusting the comb lower swing arm 207 to be hinged in different hole positions, the swing amplitude of the comb lower swing arm 207 can be adjusted.
[0042] The upper connecting rod 205 of the rear comb is hinged at both ends to the lower swing arm 207 and the upper swing arm 204 of the comb. The upper swing arm 204 of the comb is also provided with several round holes. By adjusting the hinge of the upper connecting rod 205 of the rear comb at different hole positions, the swing amplitude of the upper swing arm 204 of the comb can be adjusted. The rocker arm 201 and the upper swing arm 204 of the comb are fixed on the upper swing shaft 203.
[0043] During operation, the rotation of the rear swing cam 212, through the transmission of the aforementioned accessories, ultimately drives the yarn guide needle 202 on the rocker arm 201 to swing.
[0044] The curved shape of the rear swing cam 212 in this utility model can be designed according to the coil forming process and is related to the needle bed cam 313 and the sinking cam 408.
[0045] The needle bed mechanism includes a front needle bed 301 and a rear needle bed 302, both of which are fixedly connected to the central swing shaft 206. The bottom of the front needle bed 301 is provided with several front supports 303 and a main support 305. The front supports 303 are connected to the bearing 708 holes of the main support 305 via linear bearings 708. The main support 305 is fixedly connected to the central swing shaft 206. The bottom of the front needle bed 301 is also hinged with several front needle bed 301 connecting rods. The other end of each connecting rod is hinged to the main arm of the front needle bed 301. The main arm of the front needle bed 301 is sleeved on the outside of the front swing shaft 210. The outside of the front swing shaft 210 is also sleeved with a first cam swing arm 306, which is hinged to the needle bed cam 313.
[0046] The top of the rear needle bed 302 is provided with a tongue needle 312, and the bottom of the rear needle bed 302 is provided with at least one rear support 310. The rear needle bed 302 connecting rod is hinged to the rear support 310. The rear needle bed 302 connecting rod is hinged to the rear swing shaft 208 through a cam swing arm. The rear swing shaft 208 is connected to the main shaft 211 through the rear swing cam 212 and the needle bed cam 313.
[0047] The second cam arm 307, mounted on the rear swing shaft 208, is driven to swing by the main shaft 211 and two needle bed cams 313 mounted on the main shaft 211.
[0048] The lifting and lowering movements of the front needle bed 301 and the rear needle bed 302 are controlled by the same needle bed cam 313, and their up-and-down lifting and lowering movement curves are consistent. In order to make the lifting and lowering movement curves of the front and rear needle beds 302 differ by 180° in the rotation phase of the main shaft 211, the second cam swing arm 307 and the first cam swing arm 306 are arranged in a special 180° configuration.
[0049] The main support 305 of the 4-needle bed is fixed on the central swing shaft 206, which is in turn fixed to the lower swing arm 207 of the comb bar. As explained in the description of the rear swing section, the lower swing arm 207 is driven by the rear swing cam 212. Therefore, the main support 305 of the needle bed on the central swing shaft 206 also swings together with the lower swing arm 207. The front and rear supports 310 on the front needle bed 301 and rear needle bed 302 are connected to the main support 305 of the needle bed via bearings 708. Therefore, the latch needles 312 on the front needle bed 301 and rear needle bed 302 simultaneously perform swinging and lifting movements.
[0050] The movement of the tongue needle 312 is a complex movement, which involves both vertical and horizontal movement as well as back-and-forth swinging movement.
[0051] The main support 305 of the needle bed is equipped with two steel wires. The anti-self-closing function of the tongue of the tongue needle 312 (the opening and closing of the needle tip) can be controlled by adjusting the position of four bolts. The middle fixed part of the steel wire is used to improve the rigidity of the steel wire and can adjust the position of the steel wire.
[0052] In this embodiment, the sinking part and the swinging part in the figure are extracted separately for easy explanation. The sinking cam 408, the needle bed cam 313 and the swinging cam 212 are all fixed on the same main shaft 211. The main motor drives the main shaft 211 to rotate through the speed change. The curves of the various cams cooperate with each other to complete the work.
[0053] The settling mechanism includes a settling bed, which includes a front settling bed 401 and a rear settling bed 402. The rear settling bed 402 is fixedly connected to several main settling arms 405. The main settling arms 405 are hinged to the central swing shaft 206. The front settling bed 401 is fixed to the main settling arms 405 through a settling adjustment seat 403.
[0054] In this embodiment, the settling mechanism is driven by a main shaft 211 and two settling cams 408 mounted on the main shaft 211 to swing a first cam swing arm 306 mounted on a front swing shaft 210.
[0055] The first cam swing arm 306 drives the main settling swing arm 405, which is hinged to the central swing shaft 206, to swing via the settling connecting rod 406. The main settling swing arm 405 has a series of hinges on the central swing shaft 206. The settling bed 402 behind the machine is fixedly connected to the main settling swing arm 405, while the settling bed 401 in front of the machine is fixed to the main settling swing arm 405 via a settling adjustment seat 403. The settling adjustment seat 403 has a groove hole for adjusting the relative position of the settling plates 404 on the settling bed 401 in front of the machine and the settling bed 402 behind the machine. The rotation of the settling cam 408, through the transmission of the above-mentioned accessories, ultimately drives the settling plates 404 on the two settling beds to swing (the settling plate 404 bed in front of the machine and the settling plate 404 bed in rear of the machine are connected as one unit, and the front and rear settling plates 404 swing simultaneously in front of or behind the machine).
[0056] An installation window is provided on the right wall panel 102, and an electronic horizontal movement mechanism is installed in the installation window.

[0058] The transverse cover 604 is fixed around the transverse panel 601 and has a maintenance window 603 for easy lubrication of the bearing 708 and installation and replacement of other accessories. The bottom of the cover has several round holes for threading the wires of the transverse motor, making the wires neat and tidy.
[0059] The warp beam 707 frame includes a front crossbeam and a rear crossbeam, which are fixedly connected to the main crossbeam 103. The front crossbeam and the rear crossbeam are provided with support tubes 704, and a reinforcing angle iron 703 is also provided between the warp beam 707 frame and the main crossbeam 103.
[0060] The front crossbeam and the rear crossbeam are rotatably mounted with a set of disc heads 705. The set of disc heads 705 includes several warp shafts 707. Several disc heads 705 are spaced out on the outer side of the warp shafts 707. A bearing 708 is provided at one end of the warp shaft 707. Bearing 708 limiting rings are provided on both sides of the bearing 708.
[0061] The warp beam 707 is set up with 8 sets of warp heads 705. The bottom of the head beam and the tail beam are fixed to the crossbeam 103 of the main machine and are fixed to the crossbeam 103 of the main machine with reinforcing angle iron 703. The head beam and the tail beam are provided with support tubes 704 to connect them into a whole and improve the rigidity of the structure. The middle of the 8 sets of warp heads 705 is provided with a walkway 706 to facilitate the processing and maintenance of yarn by on-site workers.
[0062] In this embodiment, each warp shaft 707 is provided with two bearing 708 limiting rings in the tail direction, which can limit the bearing 708 on the warp shaft 707. It can be easily adjusted axially and fixed with screws when adjusted to a suitable position. The operation is convenient and can avoid the bearing 708 not being set in the appropriate position on the rear crossbeam due to the error of the machining accuracy of related parts.
[0063] It also includes a traction and winding mechanism, which includes a traction reduction motor 501. The traction reduction motor 501 is provided with a reducer shaft 507. The reducer shaft 507 drives the winding shaft 505 to rotate through a drive gear 504 and a transmission sprocket C506. The reducer shaft 507 drives the traction shaft A502 and traction shaft B503 to rotate through transmission sprockets A510 and B509. An idler wheel 508 is provided between the chains of transmission sprockets A510 and B509. Bearings 708 are provided at both ends of the traction shaft A502, traction shaft B503 and winding shaft 505, and are hinged to the left wall plate 101 and the right wall plate 102.
[0064] The drive gear 504 on the reducer shaft 507 rotates through the traction reducer. Simultaneously, the reducer shaft 507 is equipped with a transmission sprocket A510, which drives the transmission sprocket B509 to rotate via chain transmission. The traction shaft A502 has two drive sprockets B509 connected by a key; one is connected to the transmission sprocket A510 via a chain, and the other is connected to another traction shaft A502 below it via a chain, thus driving both traction shafts to rotate (they rotate in the same direction). The traction shaft B503 is connected to the traction shaft A502 via a key, and a bearing 708 is located in the middle position. An idler wheel 508 is located between the chains of the transmission sprockets A510 and B509, and an eccentric shaft is mounted on it for adjusting the chain tension.
[0065] The drive gear 504 on the reducer shaft 507 also drives the drive gear 504 on the winding shaft 505 to rotate, thereby driving the winding shaft 505 to rotate. At the same time, the winding shaft 505 is equipped with two sprockets that are driven by chains through the two sprockets C506 mounted on it, and the two winding shafts 505 rotate in the same direction.
[0066] The technical solution provided by this utility model has at least the following technical effects:
[0067] 1. In this invention, the latch needle 312 and the guide bar move in opposite directions. When the needle bed swings forward, the guide bar swings backward, and vice versa. Compared with the old-style needle bed that does not swing, this opposite movement of the needle and guide bar has the advantages of smaller guide bar swing stroke and smaller yarn tension fluctuation, which is conducive to increasing machine speed and using lower strength yarns.
[0068] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.
