Abstract

The utility model relates to a stably operating drawing component for spinning machines, with the view to solve the problems with the slipping and attrition of drawing components. The component comprises an upper pin, a middle-to-upper roller, an upper leather collar encircling the two, and a middle-to-lower roller, a lower pin, a tension bracket as well as a lower leather collar encircling the three. The middle parts of the internal surfaces of the modified upper leather collar and the lower leather collar are plain and smooth surfaces and the two sides thereof are patterned surfaces in symmetry. The adoption by the utility model of a plain surface contact in the stripping yarn moving area helps alleviate the great friction in the front jaw of the upper pin while the patterned surfaces on the two sides solve the slipping problem arising from the small contact friction between the leather collars and the roller plain surface. The transmission of the utility model is stable and can reduce slipping problems to some extent. On the same contact size, the obvious increase of the friction improves the operating stability of the dominant draw area, therefore, bringing into full play the leather collars' capacity to control fibers and the advantages of the elastic and floating jaw. Consequently, the acquired yarns are better-distributed and of a better quality.
