A kind of to-and-fro guiding device
Technical field:
The utility model relates to a kind of textile machine device, particularly a kind of to-and-fro guiding device.
Background technology:
In existing technology, fro guiding-yarn mechanism normally adopts cam-type or groove drum mechanism, but the running velocity that these mechanisms have is slow, be difficult to use in high-revolving occasion, spinning efficiency is too low, what have is serious to the yarn damage, influence the brute force of yarn, and can not change rolling density, these have all greatly restricted further developing of spinning industry, a kind of to-and-fro guiding device that is used for high-speed spinning is with regard to good this problem that solved, and a kind of to-and-fro guiding device can be used for the hundreds of rice of per minute to thousands of meters yarn winding process, thus the reel for yarn that can be applicable to more present later-model high speed fibre spinning machines and high speed cone winder fully around.
Summary of the invention:
Technical problem to be solved in the utility model is: existing cam-type fro guiding-yarn mechanism running velocity is slow, is difficult to use in high-revolving occasion, and spinning efficiency is too low.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of to-and-fro guiding device, described a kind of to-and-fro guiding device is by bearing seat, the groove rod, frame seat, guide rail, slide and yarn carrier assembly constitute, be set with a bearing seat respectively at the two ends of described frame seat, outer edge at described bearing seat is provided with two guide rail holes, in described bearing seat, be provided with bearing, the two ends of described groove rod are arranged in the bearing of described bearing seat, in outer peripheral two guide rail holes of bearing seat, two guide rails are set, described guide rail can be for cylindrical, on described guide rail, be arranged with slide, the center of described slide is provided with a slide hole and a slide groove, a described guide rail passes the slide hole, another root guide rail passes the slide groove, one end of described slide is provided with shuttle, and be connected with described shuttle, the other end of slide is connected with yarn carrier assembly, the head of described shuttle is arranged in the groove of described groove rod, described yarn carrier assembly is made of thread-carrier and guide sheet, thread-carrier is arranged on the guide sheet, and described guide sheet can be a spring leaf.
The utility model and prior art contrast, because used a kind of to-and-fro guiding device, can be when improving the yarn winding speed greatly, and easy to operate, use simple.
Description of drawings:
Fig. 1 is a kind of to-and-fro guiding device schematic diagram of the utility model.
The specific embodiment:
As shown in Figure 1, a kind of to-and-fro guiding device of the utility model, by frame seat 1, bearing seat 2, groove rod 3, guide rail 4, slide 5 and yarn carrier assembly constitute, be set with a bearing seat 2 respectively at the two ends of described frame seat 1, outer edge at described bearing seat 2 is provided with two guide rail holes, in described bearing seat 2, be provided with bearing, concrete, described bearing is a ball bearing of main shaft, the two ends of described groove rod 3 are arranged in the bearing of described bearing seat 2, in bearing seat 2 outer peripheral two guide rail holes, two guide rails 4 are set, described guide rail 4 is cylindrical, on described guide rail 4, be arranged with slide 5, the center of described slide 5 is provided with a slide hole and a slide groove, a described guide rail 4 passes the slide hole, another root guide rail 4 passes the slide groove, one end of described slide 5 is provided with shuttle 6, and be connected with described shuttle 6, the other end of slide 5 is connected with yarn carrier assembly, the head of described shuttle 6 is arranged in the groove of described groove rod 3, described yarn carrier assembly is made of thread-carrier 7 and guide sheet 8, and thread-carrier 7 is arranged on the guide sheet 8, and described guide sheet 8 is a spring leaf.
