Spindle bar capable of positioning textile bobbins

Abstract

The invention discloses a spindle blade capable of positioning a textile bobbin. The spindle blade comprises a hollow blade body (10), four openings (20) formed in the blade body (10), telescopic blocks capable of telescoping in the openings (20), levers and a center wheel, wherein one end of each lever is movably connected to one end, positioned inside the blade body, of the corresponding telescopic block; the other end of each lever is movably connected onto the center wheel. The center wheel is mounted on a transverse rod, the center wheel can rotate around the transverse rod, the transverse rod is fixed on the blade body (10), and the transverse rod passes through the axial lead of the blade body (10). When the bobbin sleeves on the spindle blade from the top down, the lower end of the bobbin can contact the telescopic blocks, the telescopic blocks retract towards the inside of the blade body, the telescopic blocks drive the levers, the levers drive the center wheel to rotate, the center wheel drives another lever and telescopic block connected onto the center wheel, and the distances that the two telescopic blocks retract towards the inside of the blade body are equivalent. Therefore, the effect of centralized positioning for the bobbin is reached, and thus the degree of twist of yarns is improved.

Description

technical field [0001] The invention relates to the field of textile machinery design, in particular to a spindle bar capable of positioning a textile bobbin. Background technique [0002] The spindle is an important part of the twisting and winding machinery in the textile machine, and is widely used in textile machinery such as wool spinning frames, twisting frames and worsted spinning frames; the bobbin is the spinning container used for the supporting operation of the spindle. The technical performance and running quality of spindles and bobbins are closely related to yarn quality, power consumption, environmental noise and labor productivity. [0003] Spindle of spinning machine is mainly composed of spindle rod, spindle plate, spindle bladder and spindle foot, etc. The spindle plate fixed on the spindle rod is the driving part of the spindle, and the spindle foot is the supporting seat of the spindle. The spindle rod rotates at high speed with the spindle as the beari...

Problems solved by technology

[0005] However, in actual operation engineering, due to the different forces on the elastic elements on the spindle bar and the different elastic coefficients of the elastic elements, although the elastic elements can clamp the bobbin, they cannot make the center of the bobbin The axis basically coincides with the central axis of the spindle bar, and then there are quality problems such as affecting the twist of the yarn
