Abstract
The utility model discloses a composite structure of an under support double-track conical steel collar and an under support steel ring. An inner track (1a) of an under support steel collar (1) and a horizontal coordinated axis form an included angle alpha 1, and alpha 1 is between 65 degrees and 89 degrees. A depression as deep as h1 is formed in the outer surface of the top of the under support steel collar, the outer end of the depression is lower than the inner end of the depression and a slope with a dip angel of alpha 2 is formed. When yarns with a under support steel ring (2) run normally on the under support steel collar (1), the under support steel ring (2) is lifted up under the acting force of F, at the same time, the a-b portion of an inner foot of the under support steel ring (2) is closely contacted with the inner track (1a) of the under support steel collar, and the c-d portion of an outer foot of the under support steel collar is closely contacted with an outer track (1b) of the under support steel collar. The composite structure of the under support double-track conical steel collar and the under support steel ring is capable of enlarging the contact area of the steel collar and the steel ring, guaranteeing smooth movement of the steel ring on the steel collar, prolonging service life of the steel ring, reducing web break and improving spinning quality.
Description
Technical field
The utility model relates to the parts on the Weaving device, is specifically related to the combining structure of a kind of lower support double course Conical rings and steel traveler.
Background technology
At present, in the rings of cotton spinning apparatus manufactures and designs, have Plane Ring and Conical rings, Conical rings is divided into again upper support Conical rings and Down Supported Conical Ring.Rings is annular element, no matter is Plane Ring, or Conical rings, and its inner track all is designed to primary runway.Figure 7 shows that the combining structure of Plane Ring and steel traveler, when normal spinning, yarn 3 is with steel traveler 2 high speed rotary on rings 1, the centrifugal force that produces makes steel traveler 2 be close to the upper operation of inner track 1a of rings 1, and steel traveler 2 is unsettled on outer track 1b, can not contact with the outer track 1b of rings 1; Be that steel traveler 2 is to contact with the inner track 1a of rings 1 in 1 mobile most times of rings, the outer track 1b of rings 1 only is secondary runway.When spinning tension suddenlyd change, outer pin possibility moment and the rings outer track 1b of steel traveler 2 collided, but can not be close to for a long time the upper normal operation of rings 1 outer track 1b.
Main Problems is: the outer pin of (1) steel traveler and rings outer track moment collide, and cause easily broken end; (2) contact length of existing rings and steel traveler is limited, the contact length of Plane Ring only is 1.5～2.5mm, the contact length of Conical rings also only has 3～5mm, make the steel traveler serious wear, service life is short, needs often to change steel traveler, simultaneously, the temperature of steel traveler is high, and the easy damaged fiber affects spinning quality; (3) steel traveler only contacts with the rings inner track, and steel traveler rocks frequently or waves in the rings easy generation that runs up, and causes the phenomenon of yarn and thread head broken end, filoplume, cotton knot obviously more.
The utility model content
The utility model aims to provide the combining structure of a kind of Down Supported Conical Ring and steel traveler, increases the contact area of rings and steel traveler, guarantees that steel traveler in the rings motion steadily, prolongs the service life of steel traveler, reduces broken end, improves spinning quality.
For this reason, a kind of lower support double course Conical rings and steel traveler combining structure that the utility model provides, comprise lower support rings (1) and lower support steel traveler (2), be provided with inner track (1a) and outer track (1b) on the described lower support rings (1), described lower support steel traveler (2) is with pin in the ab section and the outer pin of cd section, described inner track (1a) is α 1 with the angle of horizontal axis, and α 1=65～89 °, key is: it is the depression of h1 that the arranged outside at described lower support rings (1) top has the degree of depth, the outboard end of this depression is the inclined-plane of α 2 than the low formation of medial extremity inclination angle, when yarn (3) normally moves on lower support rings (1) with lower support steel traveler (2), the active force that lower support steel traveler (2) is subject to F is in puies forward running status, simultaneously, the inner track (1a) of pin and lower support rings (1) fits tightly together in the ab section of lower support steel traveler (2), and the outer track (1b) of the outer pin of the cd section of lower support steel traveler (2) and lower support rings (1) fits tightly together.
The inner track inclination alpha 1 of rings is 65～89 °, guaranteed to propose operation on steel traveler all the time, owing in the inner track bottom lower support surface is not set, pin is along carrying on the rings inner track in the ab section of steel traveler, until the outer pin of cd section contacts with the outer track of rings, steel traveler moves on just stopping, but the power of carrying on this moment still exists, the outer pin of cd section of steel traveler is fitted on the outer track of rings all the time, and this moment steel traveler the ab section in pin be subjected to the effect of centrifugal force and upper lifting force, also be close on the inner track of rings, thereby form the double course operation; In order to make the steel traveler rings of successfully packing into, having designed the degree of depth in the top outer of rings is the depression of h1, and concave bottom is provided with the inclined-plane that the inclination angle is α 2 simultaneously, and steel traveler can successfully put outer track in the rings under along depression during installation; Simultaneously, also can guarantee spacious spinning passage.
Above-mentioned inner track (1a) is arc surface or tapered plane; When inner track (1a) was arc surface, the radius of circular arc was R2, and R2=4～20mm, and inner track (1a) is α 1 angle for the string of circular arc and horizontal axis with the angle of horizontal axis.
Be preferably, in the described lower support rings (1), hem width B1=2.4～4mm, width B 2=0.5～the 2mm of top bump place, the radius R 1=0.2～1mm of top bump place, top outer cup depth h1=1～3mm, 2=5 °～20 ° of the bottom inclination angle of inclined plane α of top depression, 3=5 °～20 ° of the inboard inclination angle of inclined plane α of top depression, rings minimum wall thickness (MINI W.) h2=0.5～1.5mm, the rounding R3=0.3～1mm of top depression and protruding junction.
Further, in the described lower support steel traveler (2), pin length is 3～7mm in the ab section, and the outer pin length of cd section is 1～3mm.
The utlity model has following beneficial effect:
(1) contact area of increase rings and steel traveler, the contact length sum of its inside and outside runway can reach 6～8mm, the contact length that is much higher than Plane Ring and other Conical ringses and steel traveler greatly prolongs service life of steel traveler, than about 1～2 times of common plane rings prolongation;
When (2) normally spinning, the lower support steel traveler contacts simultaneously with the inside and outside runway of lower support rings, guarantees smooth running, and spinning tension is stable, can effectively reduce the phenomenons such as broken end, filoplume, cotton knot, improves spinning efficiency;
(3) because the contact area of lower support steel traveler and lower support rings increases, pressure is little, temperature rise is low, do not damage fiber, improves spinning quality;
(4) degree of depth is arranged is that depression and the inclination angle of h1 is the inclined-plane of α 2 to the arranged outside at lower support rings top, has guaranteed that steel traveler can successfully pack in the rings;
(5) the spinning passage is spacious, perfect heat-dissipating, and yarn qualities is good, is specially adapted to high-speed spinning.
