Description

Technical Field

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

[0002] When warp knitting machines knit fabrics of different materials, such as elastic spandex, non-elastic polyester, or fabrics with different structures, the tension and oscillation inertia of the yarns are different. Fine-tuning of the opening is required to compensate for these differences and ensure that all yarns are accurately laid. If the opening is not adjusted, yarn breakage, missed needles, or needle collisions are likely to occur. Furthermore, the opening needs to be adjusted every time the yarn variety or batch is changed. Currently, automatic opening adjustment devices driven by motors often require adjustment according to presets. However, for new types of raw materials, a manual opening adjustment device is still needed to improve the versatility of warp knitting machines. Summary of the Invention

[0003] The purpose of this invention is to provide a manual gear shifting device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a manual adjustment device for the opening and closing mechanism, comprising a warp knitting machine frame, and further comprising an opening mechanism and a manual adjustment mechanism;

There are two sets of mounting bases, which are respectively located at the left and right ends of the warp knitting machine frame. There are two first opening shafts, with their two ends respectively located in the two sets of mounting bases.

[0006] The manual adjustment mechanism includes a first adjustment cam, which consists of two sets and is respectively located at both ends of the two first opening shafts outside the warp knitting machine frame.

[0007] Preferably, the opening mechanism includes a support sleeve, a lifting screw, and a lifting cylinder. There are two sets of support sleeves, which are respectively fixedly installed on two first opening shafts. The lifting screw is fixedly installed on the top of the support sleeve, and the lifting cylinder is movably installed on the top of the lifting screw via a thread.

[0008] Preferably, the opening mechanism includes an opening bracket, a second opening shaft, and a release plate. One end of the opening bracket is movably installed on the top of the lifting cylinder. There are two second opening shafts, which are movably installed on the end of the opening bracket away from the lifting cylinder. There are two release plates, which are fixedly installed on the end of the opening bracket near the second opening shaft.

[0009] Preferably, the manual adjustment mechanism includes a second adjustment cam and a limiting groove. There are two second adjustment cams, which are respectively fixedly sleeved at both ends of a first opening shaft away from the first adjustment cam. The limiting groove is opened at the bottom end of the first adjustment cam.

[0010] Preferably, the manual adjustment mechanism includes a synchronous adjustment rod and a fixing block. One end of the synchronous adjustment rod is movably mounted on the protruding end of the first adjustment cam, and the other end is movably mounted on the protruding end of the second adjustment cam. The protruding end of the first adjustment cam is located above the first opening shaft, and the protruding end of the second adjustment cam is located below the first opening shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention incorporates an opening mechanism and a manual adjustment mechanism. By manually rotating a knob, a translation sleeve is driven to move an adjustment sleeve on a slide rod. As the adjustment sleeve moves, a movable frame drives the first adjustment cam to rotate, causing the first opening shaft to rotate simultaneously with it. Simultaneously, the rotation of the first adjustment cam drives the second adjustment cam to rotate via a synchronous adjustment rod, causing both first opening shafts to rotate at the same time. When the first opening shafts rotate, a support sleeve causes the opening bracket to swing, thereby adjusting the opening of the release plate. This improves the stability and versatility of the warp knitting machine. Attached Figure Description

There are two disengagement plates 208, which are fixedly installed on the end of the opening bracket 206 near the second opening shaft 207. By driving the two first opening shafts 202 to rotate simultaneously, when the first opening shafts 202 rotate, the opening bracket 206 is driven to swing through the support sleeve 203, thereby adjusting the opening of the disengagement plate 208.

[0027] In other aspects, this embodiment also provides a manual adjustment mechanism 3, such as... Figure 4 and Figure 5 As shown, the manual adjustment mechanism 3 includes a first adjustment cam 301. There are two sets of first adjustment cams 301, which are respectively set at both ends of the two first opening shafts 202 located outside the warp knitting machine frame 1.

[0028] In this embodiment, as Figure 4 and Figure 5 As shown, the manual adjustment mechanism 3 includes a second adjustment cam 302 and a limiting groove 303. There are two second adjustment cams 302, which are respectively fixedly sleeved at both ends of a first opening shaft 202 away from the first adjustment cam 301. The limiting groove 303 is opened at the bottom end of the first adjustment cam 301. The second adjustment cams 302 are driven to rotate simultaneously by the synchronous adjustment rod 304, so that the two first opening shafts 202 rotate simultaneously.

[0029] In this embodiment, as Figure 4 and Figure 5 As shown, the manual adjustment mechanism 3 includes a synchronous adjustment rod 304 and a fixing block 305. One end of the synchronous adjustment rod 304 is movably mounted on the protruding end of the first adjustment cam 301, and the other end is movably mounted on the protruding end of the second adjustment cam 302. The protruding end of the first adjustment cam 301 is located above the first opening shaft 202, and the protruding end of the second adjustment cam 302 is located below the first opening shaft 202. There are two fixing blocks 305, both of which are fixedly mounted on the right end of the warp knitting machine frame 1. The synchronous adjustment rod 304 causes the first adjustment cam 301 and the second adjustment cam 302 to rotate simultaneously, so that the opening adjustment of the uncoiling plate 208 is carried out synchronously.

[0030] In this embodiment, as Figure 4 and Figure 5As shown, the manual adjustment mechanism 3 includes a slide bar 306 and a movable frame 307. The slide bar 306 is fixedly installed between two fixed blocks 305, and the top of the movable frame 307 is movably installed in the limiting groove 303. The movable frame 307 drives the first adjustment cam 301 to rotate, so that the first opening shaft 202 rotates simultaneously with the first adjustment cam 301. When the first adjustment cam 301 rotates, the synchronous adjustment rod 304 drives the second adjustment cam 302 to rotate simultaneously, so that the two first opening shafts 202 rotate simultaneously.

[0031] In this embodiment, as Figure 4 and Figure 5 As shown, the manual adjustment mechanism 3 includes an adjustment sleeve 308 and a translation sleeve 309. The adjustment sleeve 308 is movably sleeved on the slide rod 306. The adjustment sleeve 308 is located between the bottom ends of the movable frame 307 and is movably connected to the movable frame 307. The translation sleeve 309 is fixedly installed at the bottom end of the adjustment sleeve 308. The translation sleeve 309 drives the adjustment sleeve 308 to move on the slide rod 306. When the adjustment sleeve 308 moves, the movable frame 307 drives the first adjustment cam 301 to rotate.

[0032] In this embodiment, as Figure 4 and Figure 5 As shown, the manual adjustment mechanism 3 includes an adjustment screw 310 and a knob 311. The adjustment screw 310 is movably installed between two fixed blocks 305 and located below the slide bar 306. The translation sleeve 309 is movably sleeved on the adjustment screw 310 via a thread. The knob 311 is movably installed on the side wall of the fixed block 305 and is fixedly connected to the adjustment screw 310. By turning the knob 311, the adjustment screw 310 is driven to rotate. When the adjustment screw 310 rotates, it moves on the adjustment screw 310 through the translation sleeve 309.

[0033] Working principle: In use, the present invention rotates by turning the knob 311, which drives the adjusting screw 310 to rotate. When the adjusting screw 310 rotates, the translation sleeve 309 moves on the adjusting screw 310, and the translation sleeve 309 drives the adjusting sleeve 308 to move on the slide rod 306. When the adjusting sleeve 308 moves, the movable frame 307 drives the first adjusting cam 301 to rotate, so that the first opening shaft 202 rotates simultaneously with the first adjusting cam 301. When the first adjusting cam 301 rotates, the synchronous adjusting rod 304 drives the second adjusting cam 302 to rotate simultaneously, so that the two first opening shafts 202 rotate simultaneously. When the first opening shaft 202 rotates, the support sleeve 203 drives the opening bracket 206 to swing, thereby adjusting the opening of the release plate 208. The distance between the lifting cylinder 205 and the support sleeve 203 can be adjusted by the lifting screw 204, so as to make more precise adjustment of the opening.
