Abstract
The utility model belongs to the field of textile machinery, and proposes a novel upper drawing pin of a spinning machine, which is mainly characterized in that a pressure bar adopts a meniscate pressure bar, and the included angle between the bastard face of the pressure bar and the lower part surface of a leather ring ranges from 0 to 90 degrees. The utility model not only has the advantages of simple structure, ideal prevention of upturning of fed slivers and remarkable improvement of uniformity of the slivers, but also has favorable operation and satisfying effect as practiced, thereby being especially suitable for improving the upper drawing pins of the spinning machine and being popularized in roving machines.
Description
Technical field
The utility model belongs to field of textile machinery, relates to drafting assembly of spinning frame, is specifically related to sell in a kind of fine spining machine drawing-off.
Background technology
Existing weaving loom comprises Speed frames, fine spining machine, and the cotton-wool bar is earlier after Speed frames and fine spining machine drawing-off resultant yarn, and the pin of going up of its drafting system comprises top-pin rack, rubber roll, apron and pressure bar.Original pressure bar is cylindrical, and particularly the cotton-wool bar through being fed into fine spining machine after the Speed frames drawing-off turns on easily, causes frequent broken end, and the resultant yarn bar evenness also is under some influence.
Turn over problem in order to solve on the cotton-wool bar, someone is through improving, change the cylindrical pressure rod into tadpole shape pressure bar, though having overcome on the cotton-wool bar preferably, its tip turns over problem, but because the bottom cambered surface contact cotton-wool bar of tadpole shape pressure bar is still longer, the district's change of swimming is less, though the resultant yarn bar evenness there is improvement, it is still undesirable to improve effect.
Summary of the invention
The inventor is in being engaged in textile machine Operation and maintenance practice for many years, find existing spinning machine, particularly the drafting system of fine spining machine exists certain defective, by analysis, constantly explore, purpose is pin in the drawing-off of spinning machine is improved, and proposes to sell in a kind of novel fine spining machine drawing-off, can solve preferably to turn on the feeding cotton-wool bar and improve resultant yarn bar evenness problem.
Technical solution adopted in the utility model is to sell in a kind of fine spining machine drawing-off of design, and its structure comprises: the top-pin rack of selling in the fine spining machine drawing-off, rubber roll, apron, pressure bar, wherein pressure bar is the selenodont pressure bar, and the angle of the string face of pressure bar and the bottom surfaces of apron is spent less than 90 greater than 0.
Wherein the string face of selenodont pressure bar is crescent or half moon tooth string face on the lower side.
The utility model adopts abovementioned technology to after pin is improved on the existing spinning machine drafting, because the string face of selenodont pressure bar is surrendered two approximate corner angle mutually with arcwall face, the pressure bar corner angle of portion on the upper side still can keep preventing to turn on the cotton-wool bar, the corner angle of pressure bar bottom are changed into the crest line contact with contacting by cambered surface of cotton-wool bar, swim to distinguish and significantly be reduced to least limit, thereby the uniformity that becomes sliver to do significantly improves, compare with selling in the existing weaving loom drawing-off, have simple in structurely, can better prevent to feed and turn over and significantly improve advantages such as resultant yarn bar evenness on the cotton-wool bar.
Description of drawings
Fig. 1 represents that the structure master who sells in the drawing-off of the utility model fine spining machine looks schematic diagram;
Schematic diagram is looked on the structure left side of Fig. 2 presentation graphs 1.
The specific embodiment
In conjunction with the accompanying drawings and embodiments, further specify the concrete structure of selling in the drawing-off of the utility model fine spining machine, its feature and advantage are clearer.
The embodiment that sells in the drawing-off of the utility model fine spining machine, referring to Fig. 1, Fig. 2, its structure comprises: top-pin rack 1, pressure bar 2.1,2.2, rubber roll, apron (not shown), its pressure bar 2.1,2.2 cross section be crescent or half moon tooth form on the lower side, during installation, the string face of crescent or half moon tooth form pressure bar and apron bottom on the lower side and angle cotton-wool bar contact-making surface greater than 0 degree less than 90 degree.
Sell in this fine spining machine drawing-off of the present utility model, be suitable for most pin in the fine spining machine drawing-off is transformed, also be suitable for to Speed frames traction and go up pin and apply, on probation through the model machine installation, operational excellence prevents to turn on the cotton-wool bar, and expression effects such as resultant yarn bar evenness are satisfactory.
