Abstract
The utility model discloses a pressure bar spacer with grooves, which comprises a spacer and pressure bars, wherein the pressure bars are fixed at the left end and the right end of the spacer, an inverted triangular concave groove I and a triangular concave groove II are arranged on bilaterally symmetrical side walls of the pressure bars, the concave groove I is arranged above the concave groove II, the concave surface of the concave groove I is larger than that of the concave groove II, and the tip bottom surface of the concave groove I is rightly jointed with the tip top surface of the concave groove II. By aid of the press bar spacer with grooves, yarns can pass through a drafting area effectively, thereby increasing friction among fibers, increasing evenness of yarns, and reducing fiber loss and hairness index simultaneously.
Description
Technical field
The utility model relates to a kind of press bar distance clip that uses on the fine spining machine in textile machine.
Background technology
Press bar distance clip is that the drawing-off friction field is redistributed, take the technological measure of additional friction power circle at the spun yarn main drawing area, strengthened the control of counter extensioin district floating fiber, slow down that turn heavily distributes and the phenomenon of fiber partial fracture, to improving the resultant yarn bar evenness, reduction km slubbing, km details, km cotton knot have obvious effects.Effect is more obvious when especially spinning the yarn of 18.2～7.9tex.Therefore there is bigger influence in working pressure rod spacing block to yarn qualities in the spinning process in spinning process.
But working pressure rod spacing block can increase the friction of fiber, increases the hairiness index of yarn, and yarn qualities is had a negative impact, and can cause that in addition the sliver drawing-off do not leave the phenomenon that hardhead causes broken end.The existing patent such as the patent No. are " CN200820082117.9 ", patent name is that " special-shaped curved press bar distance clip " and the patent No. are " CN200620075919.8 ", and patent name is that " two-region, two sides controlled pressure bar device " all do not solve the problem that exists fully.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of press bar distance clip of with groove, and its technical scheme of taking is:
Comprise spacing block and the pressure bar that is fixed on two ends, the spacing block left and right sides, on the symmetrical sidewall of pressure bar, have the concave groove I that is del and concave groove II triangular in shape, concave groove I be positioned at concave groove II directly over and its groove face greater than the groove face of concave groove II, the pointed bottom surface of concave groove I and the pointed end face of concave groove II join just.
Concave groove I and concave groove II are 35mm apart from the center position of spacing block.
Because have concave groove I and concave groove II on the pressure bar, yarn can pass through draw zone effectively, increase the frictional force between the fiber, improve the bar evenness of yarn; Reduce fiber simultaneously and scatter and disappear, reduce hairiness index.The utlity model has simple in structurely, easy to use, guarantee the characteristics of yarn qualities.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Pressure bar 1 is fixed on the two ends, the left and right sides of spacing block 2, have the concave groove I3 that is del and concave groove II4 triangular in shape on the left and right sides sidewall at the 35mm place, center of spacing block at pressure bar 1, concave groove I3 be positioned at concave groove II4 directly over, and its groove face is greater than the groove face of concave groove II4, concave groove I3 import is 9mm, concave groove II4 outlet is 2mm, and the pointed bottom surface of concave groove I3 and the pointed end face of concave groove II4 join just, two groove faces are communicated be streamlined.
Yarn enters from the import of concave groove I3 during use, comes out from the outlet of concave groove II4, can make yarn effectively by draw zone, increases the frictional force between the fiber, improves the bar evenness of yarn; Reduce fiber simultaneously and scatter and disappear, reduce hairiness index.
