Abstract
The invention relates to a lower pin of the spinning machine non-winding leather collar which the cross-section is 'T'shape. The working face is made up of a section of oblique plane and a section of curved face. The whole height L2 is 24-27mm and the whole width L1 is 18-23.5mm; the step height L3 is 3-4.5mm; the small arc R2 is 0.5-1.5mm; the angle alpha between the slant and the horizon plane is 0: to 30: ; the diameter R1 of curve face is 30-60mm. the distance from R1 circle center to lower pin reinforced rib left side is 5-8mm. the invention can increase the friction force between the top and lower pin to control the fiber and make the lower leather collar rotate agility, also it can banish the winding leather collar to ensure the yarn quality.
Description
Technical field:
The invention belongs to a kind of part of fine spining machine, be specifically related to a kind of downside pin of spinning machine twisting-free leather collar.
Background technology:
Downside pin is one of critical piece in the drafting system, directly acts on the gripping and the drawing-off of fiber strip, and the motion of controlling fiber is played an important role, and is therefore huge to the yarn quality influence.The present drafter of cotton mill ring throstle relies on mainly that pin and downside pin same-action come controlling fiber on drawing rollers, rubber roll, apron, the elasticity, realizes drawing-off.Mechanism's formed intermediate friction power bound pair controlling fiber motion that pin and downside pin are formed on apron, the elasticity, the quality that guarantees the drawing-off sliver has decisive role, existing downside pin well counter extensioin sliver fiber carries out strong control, and because existing downside pin wider width, cause the gap between downside pin rear end and the middle roller less, the strand phenomenon of apron down takes place easily.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of downside pin of spinning machine twisting-free leather collar, it can increase the frictional force that goes up between pin and the downside pin, and fiber is carried out strong control, and apron is rotated flexibly, and eliminated strand apron phenomenon, final assurance improves quality of yarn.
The technical solution adopted in the present invention: it is "T"-shaped that twisting-free leather collar downside pin section is curved surface, its working face is made up of one section tapered plane 1 and one section curved surface 2, total height L2 is 24 to 27 millimeters, overall width L1 is 18 to 23.5 millimeters, the high L3 of step is 3 to 4.5 millimeters, and roundlet arc R2 is 0.5 to 1.5 millimeter, and the angle [alpha] of inclined-plane and horizontal plane is that 0 degree is to 30 degree, the radius R 1 of curved surface 2 is 30 to 60 millimeters, and the center of circle of R1 is 5 to 8 millimeters to the distance of downside pin reinforcement left surface.
The present invention has following beneficial effect: the frictional force in the increase between pin and the downside pin, fiber is carried out strong control, and fiber is carried out strong control, apron is rotated flexibly, and eliminated strand apron phenomenon, finally guaranteed quality of yarn.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment: it is "T"-shaped that twisting-free leather collar downside pin section is curved surface, its working face is made up of one section tapered plane 1 and one section curved surface 2, total height L2 is 26.25 millimeters, overall width L1 is 21 millimeters, the high L3 of step is 4.5 millimeters, and roundlet arc R2 is 1 millimeter, and the angle [alpha] of inclined-plane and horizontal plane is 16 degree, the radius R 1 of curved surface 2 is 40 millimeters, and the center of circle of R1 is 5.8 millimeters to the distance of downside pin reinforcement left surface.
