2results about How to "Stable pay-off" patented technology

The utility model provides a threading pay-off reel. The threading pay-off reel comprises a support; the central shaft is arranged on the support; the wire coiling and uncoiling mechanism is rotatably arranged on the central shaft in a sleeving manner, and the wire coiling and uncoiling mechanism is used for coiling and uncoiling a wire; the limiting mechanism is arranged on the central shaft, and the limiting mechanism is used for limiting the distance between the coil pay-off mechanism and the support; and the speed reducing mechanism is arranged between the central shaft and the coil pay-off mechanism in a sleeving manner, and the speed reducing mechanism is used for reducing the pulling resistance during pay-off and reducing the rotating speed. Therefore, controllable outer ring pay-off is achieved through the speed reducing mechanism, a worker can easily control the pay-off process, violent operation such as wire falling is not needed, and the intact wire skin and the wire performance are effectively kept; meanwhile, harmful substances such as waste engine oil are abandoned, stable paying-off is achieved through the mechanical speed reducing mechanism, construction efficiency is improved, and construction safety is guaranteed.

The utility model belongs to the field of yarn anti -drop device, specifically speak to a kind of yarn anti -drop device for computer flat knitting machine, the horizontal frame of computer flat knitting machine upper portion is inserted with barb, and the threaded hole of barb is fixedly connected with bolt, and the end of barb is fixedly connected with locating disc, and the end of locating disc is fixedly connected with rotating disc, and the groove of rotating disc is slidably connected with sliding element, and the end of sliding element is fixedly connected with dilatant, and the side of dilatant is fixedly connected with friction pad, and the end of yarn cylinder is close to rotating disc, and is inserted in place, through this process, through hole can move along with guide column, and spring is also compressed, after yarn cylinder is inserted in place, spring releases elastic force, sliding element is driven to exert thrust towards another direction, so that dilatant can be close to the inner wall of yarn cylinder, and the friction pad set on the outer wall of dilatant can increase the friction force with yarn cylinder, rotating shaft can also produce rotation when yarn is pulled, and yarn cylinder is pulled to rotate.
