Abstract
A drafting machine for a pressure rod is provided. When a cradle is pressed down, a back pressure rod (4) presses a slub (8) and an ultrathin bottom apron (14) into a scarf (11), the slub moves forwards in an S-shape and forms a frictional boundary on the surface of a bottom apron (12) at the arc bank (10) of a bottom pin (12). A front pressure rod of a spacer (3) presses against the floating area of the slub (8), so that the slub (8) between the front and the back pressure rods (2) and (4) sinks into the flute (16) of the bottom apron (12), the flute (16) plays the role of a slub collector. As the front pressure rod (2) controls the fiber diffusion of the floating area of the slub (8), the drafting machine for the pressure rod of the invention reduces the yarn hairiness and improves the yarn quality.
Description
Technical field
The present invention relates to a kind of ring throstle, particularly the drafting system on the fine spining machine.
Background technology
Present existing drafting assembly of spinning frame all is three rollers, apron drafting arrangement up and down.Their shortcoming is: the reel cage pressure that needs is big, power consumption is high.The apron damage is fast up and down, spinning cost is high, and bar is done inequality, Yarn filoplume is many, flyings are many.
Summary of the invention
Because the deficiency of above-mentioned technology, the present invention takes measures to be: design a kind of convex S face downside pin (12), be provided with 1-N bar chase (11) on the surface of downside pin (12), be provided with the arc dike (10) of 1-N road projection in the both sides of every chase (11), replace traditional T type downside pin with downside pin (12).At one side of the surperficial forward roller of downside pin (12) design 1-10 groove (16).The ultra-thin apron (14) down that is no more than 1mm with thickness is replaced tradition apron down.On spacing block (3) the card S shape spring (5), S shape spring is fixed on the reel cage, replaces pin traditionally with S shape spring.Pressure bar (4) after being provided with a preceding pressure bar (2) and 1-N root on the spacing block (3) is replaced apron traditionally with back pressure bar (4).Preceding pressure bar (2) is being pressed the district of swimming of rove fiber, the fiber diffusion that prevents to swim and distinguish. back pressure bar (4) is being pressed on the following apron (14) that is enclosed within on the downside pin (12), and apron (14) is pressed in the chase (11) of downside pin (12) under the handle, makes by the rove bar under the back pressure bar (4) S-shaped.Iron roll in replacing with medium rubber roller. the invention has the beneficial effects as follows: deduct on the existing drafting system basis up and down apron, on pin etc., reduced electricity consumption, reduced cost, improved the yarn evenness quality, reduced filoplume.
Description of drawings
The contrast accompanying drawing is described in further detail the present invention below.
Fig. 1 is the side-looking structural representation of press bar drafting device of the present invention.
Fig. 2,3,4 is side-looking structural representations of downside pin and spacing block in the press bar drafting device of the present invention.
Fig. 5 is the plan structure schematic diagram of downside pin in the press bar drafting device of the present invention.
Fig. 6 is the plan structure schematic diagram of spacing block in the press bar drafting device of the present invention.
Among the figure, front leather roller (1), preceding pressure bar (2), spacing block (3), back pressure bar (4), spring (5), medium rubber roller (6), back roller (7), rove (8), front roller (9), arc dike (10), chase (11), downside pin (12), middle roller (13), following apron (14), rear roller (15), groove (16).
The specific embodiment
When depressing reel cage, back pressure bar (4) is just compressed into chase (11) to rove (8) and ultra-thin apron (14) down, S-shaped the travelling forward of rove (8), rove (8) also is in down at the arc dike (10) of downside pin (12) that the surface of apron (12) forms friction circle.The preceding pressure bar (2) of spacing block (3) has been pushed down the district of swimming of rove (8), so front and back pressure bar (2). and the rove between (4) (8) just falls in the groove (16) of downside pin (12) into, so groove (16) just plays the effect of collection yarn device.Again because preceding pressure bar (2) is controlled the swim diffusion of fiber in district of rove (8), so press bar drafting device of the present invention has reduced Yarn filoplume, improved quality of yarn.
Claims (4)
1, a kind of press bar drafting device: back three rollers (9) in before comprising. (13). (15) is characterized in that: design a kind of convex S face downside pin (12), replace traditional T type downside pin; The ultra-thin apron (14) down that is no more than 1mm with thickness is replaced tradition apron down; Spacing block (3) is stuck on the S shape spring (5), and S shape spring (5) is fixed on the reel cage, replaces pin traditionally with S shape spring (5); With iron roll in medium rubber roller (6) replacement.
2, a kind of press bar drafting device according to claim 1 is characterized in that: be provided with 1-N bar chase (11) on the surface of downside pin (12), be provided with the arc dike (10) of 1-N road projection in the both sides of every chase (11)
3, it is characterized in that according to claim 1,2 described a kind of press bar drafting devices: surperficial forward roller (1) design on one side at downside pin (12) has 1-N groove (16).
4, a kind of press bar drafting device according to claim 1 is characterized in that: pressure bar (4) after establishing a preceding pressure bar (2) and 1-N root on the spacing block (3).
