Description

Technical Field

[0001] This invention relates to the field of warp knitting machine technology, specifically to a dynamic balancing drive device. Background Technology

[0002] The working principle of a warp knitting machine is that the main shaft, through a complex set of connecting rods, eccentric wheels, or conjugate cam mechanisms, converts continuous rotary motion into reciprocating motions with specific patterns required by the knitting machine components such as guide bars, needle beds, and sinker beds. Modern high-speed warp knitting machines can reach main shaft speeds of 3000-4000 rpm or even higher. During high-speed operation, these reciprocating components generate enormous, periodically changing inertial forces. This unbalanced force can lead to severe vibrations, affecting machine stability, even causing the foundation to loosen, generating high noise levels, worsening the working environment, accelerating wear, and affecting the lifespan of bearings, guide rails, and other parts. Vibrations can also cause micron-level deviations in the relative positions of the knitting needles and guide needles, resulting in defects such as missed needles and needle collisions, which are particularly fatal when producing high-end fabrics. The core purpose of the dynamic balancing drive device is to generate a balancing force equal in magnitude and opposite in direction to these unbalanced inertial forces, thereby canceling them out and ensuring smooth machine operation.

[0003] The dynamic balancing drive devices used in existing warp knitting machines usually require adjustment of the cams according to the actual conditions produced by the warp knitting machine. However, the cams are difficult to remove during adjustment, which makes the adjustment inconvenient. Therefore, a dynamic balancing drive device that makes it easy to install or remove the cams for maintenance is needed. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This embodiment provides a dynamic balancing drive device, such as... Figures 1 to 7 As shown, it includes a drive shaft 1, which has two shafts, and also includes a dynamic balance adjustment mechanism 2, a coupling mechanism 3, a fixing mechanism 4, and a drive mechanism 5.

[0029] The dynamic balancing mechanism 2 includes a dynamic balancing cam 201, an adjusting ring 202, and a counterweight 203. There are two dynamic balancing cams 201, which are respectively set on two drive shafts 1. The adjusting ring 202 is set on the dynamic balancing cam 201, and the counterweight 203 is set on the dynamic balancing cam 201.

[0030] At other levels, this embodiment also provides a coupling mechanism 3, such as... Figure 4 and Figure 5 As shown, the coupling mechanism 3 includes a connecting cylinder 301 and a telescopic cylinder 302. The connecting cylinder 301 is disposed between the two drive shafts 1, and there are two telescopic cylinders 302, which are respectively disposed at both ends of the connecting cylinder 301.

[0031] In this embodiment, as Figure 4 and Figure 5 As shown, the coupling mechanism 3 includes a translation groove 303 and a push-pull block 304. The translation groove 303 is opened at both ends of the connecting cylinder 301. There are two sets of push-pull blocks 304, which are fixedly installed at the upper and lower ends of the two telescopic cylinders 302 respectively, and are located at the end of the telescopic cylinder 302 near the middle of the connecting cylinder 301. The push-pull block 304 is movably installed in the translation groove 303.

[0032] By placing the connecting cylinder 301 between the two drive shafts 1, the push-pull block 304 is pushed, which in turn drives the telescopic cylinder 302 to move into the drive shaft 1.

[0033] At other levels, this embodiment also provides a fixing mechanism 4, such as Figures 3 to 5 As shown, the fixing mechanism 4 includes two rotating wheels 401, which are respectively located in the two telescopic cylinders 302 at one end away from the connecting cylinder 301.

[0034] In this embodiment, as Figures 3 to 5As shown, the fixing mechanism 4 includes a straight groove 402, a telescopic block 403, and a translation rod 404. The straight groove 402 has four evenly distributed grooves on each rotating wheel 401. The telescopic block 403 is movably installed inside the telescopic cylinder 302, and one end of the telescopic block 403 is movably installed inside the straight groove 402. The end of the translation rod 404 away from the middle of the connecting cylinder 301 is fixedly connected to the middle of the straight groove 402.

[0035] The rotating wheel 401 drives the translation rod 404 to move simultaneously. When the translation rod 404 rotates, it drives the rotating wheel 401 to rotate. When the rotating wheel 401 rotates, it drives the telescopic block 403 to extend out of the telescopic cylinder 302 through the straight groove 402.

[0036] In this embodiment, as Figures 3 to 5 As shown, the fixing mechanism 4 includes a limiting strip 405, a guide groove 406, and a slot 407. The limiting strip 405 is fixedly installed on the end of the translation rod 404 away from the straight groove 402. The guide groove 406 is opened inside the drive shaft 1. The telescopic block 403 is movably installed in the guide groove 406. The slot 407 is opened on the drive shaft 1. The telescopic block 403 is inserted into the slot 407.

[0037] The translation rod 404 drives the rotating wheel 401 to rotate. When the rotating wheel 401 rotates, the straight groove 402 drives the telescopic block 403 to move out of the telescopic cylinder 302, so that the telescopic block 403 enters the slot 407. After the telescopic block 403 enters the slot 407, the position of the telescopic cylinder 302 is fixed with the drive shaft 1 and the connecting cylinder 301.

[0038] At other levels, this embodiment also provides a driving mechanism 5, such as... Figure 5 As shown, the drive mechanism 5 includes a support frame 501. There are two support frames 501, which are located in the middle of the inside of the connecting cylinder 301.

[0039] In this embodiment, as Figures 5 to 7 As shown, the drive mechanism 5 includes a rotating shaft 502, a limiting groove 503, and a worm gear 504. The rotating shaft 502 is movably mounted on two support frames 501. The limiting groove 503 is opened at both ends of the rotating shaft 502. The translation rod 404 and the limiting strip 405 are inserted and installed in the limiting groove 503. The worm gear 504 is fixedly sleeved on the rotating shaft 502 and is located between the two support frames 501.

[0040] By driving the worm gear 504 to rotate, the limiting groove 503 is driven to rotate, and the limiting groove 503 is fixed in the middle of the inside of the connecting cylinder 301 by the support frame 501.

[0041] In this embodiment, as Figures 5 to 7As shown, the drive mechanism 5 includes a worm 505, a fixed seat 506, and a limiting seat 507. The worm 505 is movably disposed inside the telescopic cylinder 302 and located below the worm wheel 504, and is movably connected to the worm wheel 504 through meshing. The fixed seat 506 is fixedly installed in the middle of the telescopic cylinder 302, and the limiting seat 507 is fixedly installed at the end of the fixed seat 506 located outside the telescopic cylinder 302.

[0042] The worm gear 505 drives the worm wheel 504 to rotate, causing the rotating shaft 502 to rotate simultaneously with the worm wheel 504. While the telescopic cylinder 302 moves, the rotating wheel 401 drives the translation rod 404 to move simultaneously, causing the limiting strip 405 to slide in the limiting groove 503. As the limiting groove 503 rotates, the translation rod 404 rotates simultaneously.

[0043] In this embodiment, as Figures 5 to 7 As shown, the drive mechanism 5 includes a rotating cylinder 508, a telescopic rod 509, and a limiting block 510. The rotating cylinder 508 is movably installed inside the fixed base 506, and one end of the rotating cylinder 508 is fixedly connected to the worm gear 505 inside the telescopic cylinder 302. The telescopic rod 509 is movably installed inside the rotating cylinder 508, and the limiting block 510 is fixedly installed at one end of the telescopic rod 509 near the worm gear 505.

[0044] The limit frame 511 drives the telescopic rod 509 to rotate, and the limit block 510 drives the rotating cylinder 508 to rotate simultaneously, so that the rotating cylinder 508 can drive the worm gear 505 to rotate.

[0045] In this embodiment, as Figures 5 to 7 As shown, the drive mechanism 5 includes a limit frame 511, a spring 512, and a counterweight column 513. The limit frame 511 is fixedly installed at one end of the telescopic rod 509 outside the rotating cylinder 508. The limit frame 511 is movably installed inside the limit seat 507. The spring 512 is located inside the rotating cylinder 508 and is movably sleeved on the telescopic rod 509, and is located between the limit seat 507 and the limit block 510. There are three counterweight columns 513, which are fixedly installed in the middle of the outer side wall of the telescopic cylinder 302.

[0046] By pulling out the limit frame 511, the limit block 510 moves outward, causing the spring 512 to be compressed. After the limit frame 511 is pulled out from the limit seat 507, the limit frame 511 is rotated, which drives the rotating cylinder 508 to rotate simultaneously through the limit block 510. The rotating cylinder 508 drives the worm gear 505 to rotate.

[0047] Working Principle: In use, two dynamic balancing cams 201 are placed at both ends of two drive shafts 1, and then the connecting cylinder 301 is placed between the two drive shafts 1. At this time, the push-pull block 304 is pushed, which drives the telescopic cylinder 302 to move inward into the drive shaft 1, so that the telescopic block 403 moves along the guide groove 406 to the slot 407. Then, the limit frame 511 is pulled out. When the limit frame 511 moves outward, it drives the limit block 510 to move simultaneously. At this time, the spring 512 is compressed. After the limit frame 511 is pulled out from the limit seat 507, the limit frame 511 is rotated, which drives the rotating cylinder 508 to rotate simultaneously through the limit block 510. The rotating cylinder 508 drives the worm gear 505 to rotate, which drives the worm wheel 504 to rotate, so that the rotating shaft 502 rotates simultaneously with the worm wheel 504. While moving, the rotating wheel 401 drives the translation rod 404 to move simultaneously, causing the limiting strip 405 to slide within the limiting groove 503. As the limiting groove 503 rotates, the translation rod 404 rotates simultaneously, which in turn drives the rotating wheel 401 to rotate. When the rotating wheel 401 rotates, the straight groove 402 drives the telescopic block 403 to move outward from the telescopic cylinder 302, causing the telescopic block 403 to enter the slot 407. After the telescopic block 403 enters the slot 407, the telescopic cylinder 302 is fixed in position with the drive shaft 1 and the connecting cylinder 301. At this time, driving one drive shaft 1 to rotate will drive the other drive shaft 1 to rotate simultaneously, causing the dynamic balancing cam 201 mounted on the drive shaft 1 to rotate simultaneously, thereby performing dynamic balancing operations on the warp knitting machine. Dynamic balancing is adjusted by rotating the adjusting ring 202 on the dynamic balancing cam 201.
