Abstract

The invention provides a drafting device of a drawing frame, belonging to the technical field of textile machinery. The drafting device comprises a roller mechanism and an intermittent rotary pressure bar mechanism, wherein the roller mechanism comprises a first roller component and a second roller component; the intermittent rotary pressure bar mechanism is arranged between the first roller component and the second roller component; a pressure bar of the intermittent rotary pressure bar mechanism is arranged at one end of an output shaft; a one-way clutch is arranged on the output shaft; an idler wheel fulcrum is arranged outside the one-way clutch; an idler wheel is arranged at one end of the idler wheel fulcrum in a rotatable manner; one end of a spring is connected with the idler wheel fulcrum and the other end is connected with a support base; a sliding cam is arranged on the support base in a slideable manner; the idler wheel always keeps fit with the sliding cam under the action of the spring; the body of an oil cylinder is horizontally fixed on an oil cylinder support; one end of a piston rod is connected with the sliding cam. The drafting device utilizes intermittent rotary pressure bar curvilinear drafting, thus not only reducing accumulated fibers of the pressure bar but also greatly reducing yarn faults.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a drawing frame drafting device. Background technique [0002] The function of the drawing frame is to improve the internal structure of the sliver, thereby improving the uniformity of its long segments, and at the same time reducing the unevenness of the weight, making the fibers in the sliver straight and parallel, reducing hooks, making the fineness meet the requirements, and making different types or Raw materials of different qualities are mixed evenly to achieve the specified mixing ratio. The drawing frame is composed of feeding part, drafting part, strip forming part and some automatic devices. At present, almost all the drafting devices of the new draw frames adopt the pressure bar curve drafting. The essence of the pressure bar curve drafting is to install a pressure bar between the first and second rollers in the main drafting area. The stroke of the strand...
