Abstract
The utility model discloses an upper pin pressure bar applied to a spinning frame, which comprises a bracket used for being arranged on an upper pin of the spinning frame and a pressure bar clamped on the bracket; the upper end of the bracket is connected with the spinning frame in an upper pin manner, and the lower end of the bracket is provided with a pressure rod in a limiting manner. In the application, the pressure bar is arranged on the upper pin of the spinning frame and used for increasing friction in the line conveying process, and the effect of controlling fiber movement is achieved on the coarse yarn, so that an accessory friction interface is established, drafting control on the rear-area yarn is facilitated, yarn evenness is improved, and fiber nep effect is reduced.
Description
Technical Field
The utility model relates to the technical field of textile auxiliary equipment, in particular to an upper pin pressure bar applied to a spinning frame.
Background
A spinning machine, wherein in the spinning process, semi-product roving or sliver is drawn, combined and wound into spun yarn cop, the sliver is drawn and combined on the roving machine to be made into roving, the fiber is combed into combed sliver by a combing machine, the sliver is combined by a gill box, the sliver structure is improved by the needle draft, the roving is further combined on the ring spinning machine to be spun into spun yarn, and the spinning machine is a main machine for spinning;
the upper pin of the conventional spinning frame is free of pressure bars, the yarn length uniformity is 13.96, the neps are 332, and the relative nep amount is large; thus, the fiber is easy to be poor in straightening degree, and the evenness and nep are easy to be deteriorated.
Disclosure of Invention

Detailed Description
The embodiment discloses an upper pin pressure bar applied to a spinning frame, which comprises a bracket 2 used for being arranged on an upper pin of the spinning frame and a pressure bar 3 clamped on the bracket 2;
the upper end of the bracket 2 is connected with the spinning frame in an upper pin manner, and the lower end of the bracket is provided with a pressure rod 3 in a limiting manner.
As shown in fig. 4, a screw hole 21 for connecting an upper pin of the spinning frame is formed at the upper end of the bracket 2, a claw 22 is integrally formed at the lower end of the bracket 2, and a clamping groove 23 for installing the pressure bar 3 is formed on the claw 22; wherein the clamping groove 23 has a circular arc structure.
In another embodiment, two claws 22 are symmetrically arranged at the lower end part of the bracket 2, and a fixed clamping sleeve 4 is sleeved on the pressure rod 3, and the fixed clamping sleeve 4 is clamped between the two claws 22;
the pressure bars 3 arranged on the upper pin are metal bars, and the pressure bars 3 on two sides of the fixed clamping sleeve 4 are simultaneously contacted with the lines; the friction device is used for increasing friction in the line conveying process, has the effect of controlling fiber movement on the coarse strips, establishes an accessory friction interface, and is beneficial to controlling the drafting of the rear-area strips, thereby achieving the effects of improving yarn evenness and reducing fiber neps.
Wherein, under the condition of no pressure rod, the yarn length uniformity is 13.96, and the neps are 332 grains;
with the pressure rod, the yarn length uniformity is 13.79, the neps are 301, and the yarn is reduced by 10%.
The foregoing embodiments are merely illustrative of the preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to which the present utility model pertains should fall within the scope of the utility model as defined in the appended claims without departing from the spirit of the utility model.
