The utility model comprises an upper compression roller device (11) arranged between the middle roller group and the rear roller group, a lower compression roller (10) arranged between the middle roller group and a upper compression roller device (11). The upper compression roller device (11) is fixed on the air pressing cradle (1) through the installation frame (4), the lower section of the installation frame is connected with supporting shaft (12), and the end of the supporting shaft (12) is compression roller (5). The lower compression device (10) comprises strip compression bar (6), the both ends are embedded in the hole and slot of the middle and lower roller sliding base (7). The utility model has obvious increasing effect to the textile spinning frame V-shaped draft and plane draft rear area friction field, the rear area fiber control is increased effectively, and has the active effects of improving yarn evenness and enhancing spinning quality.
Description
" technical field " the utility model relates to a kind of drafter of the fine spining machine of weaving, and particularly belongs to a kind of servicing unit that can increase weaving fine spining machine drawing-off back zone friction field.
" background technology " mainly contains two kinds of drawing-off forms, plane drawing-off and V-arrangement drawing-off when first three roller ring spinning frame.The simple roller counter extensioin that its drawing-off back zone is linked up and formed by the friction field of two pairs of each self-formings of roller.The intensity of middle part, drawing-off back zone friction field is the most weak, and what kept is interfibrous cohesive force, and the ability of controlling fiber is relatively poor, makes the speed change point of staple fibre unstable, worsens the product bar and does, thereby influence product quality.In No. 200520086523.9 patent disclosures of first to file a kind of weaving fine spining machine V-arrangement drafter, by between middle roller group and rear roller group, the rotation press-roller device being set, increased the lip-deep encirclement arc length of back bottom roll, reduced length of floating area, friction field has been strengthened in back zone to the V-arrangement drawing-off, but for plane drawing-off DeGrain then.
" summary of the invention " the purpose of this utility model is intended to overcome above-mentioned deficiency, a kind of novel weaving fine spining machine drawing-off back zone servicing unit is provided, strengthen three roller ring spinning frame drawing-off back zone friction fields to reach, improve spinning quality then and the purpose of quality control ability.
Weaving fine spining machine drawing-off disclosed in the utility model back zone servicing unit, comprise and being installed on by the middle roller group of middle top roller (9) and middle bottom roller (8) formation, by the last press-roller device (11) between the rear roller group of back top roller (2) and back bottom roll (3) formation, the described press-roller device (11) of going up is fixed on the pneumatic pressurizing cradle (1) by installing rack (4), the hypomere of installing rack connects back shaft (12), and back shaft (12) end is pressure roller (5); It is characterized in that be provided with lower compression roller device (10) between middle roller group and last press-roller device (11), described lower compression roller device (10) comprises a bar shaped depression bar (6), its two ends are flush-mounted in the hole or groove of middle bottom roller slide (7).
Weaving fine spining machine drawing-off disclosed in the utility model back zone servicing unit, by press-roller device (11) and lower compression roller device (10) are set between middle roller group and rear roller group, the effect that the back zone friction field of weaving fine spining machine V-arrangement drawing-off or plane drawing-off is all had obvious enhancing, thereby the back zone fiber has been increased effective control, shortened length of floating area, had and improve the good effect that bar is done, improved spinning quality.
" description of drawings " accompanying drawing partly discloses specific embodiment of the utility model, wherein:

" specific embodiment " as shown in Figure 1, weaving fine spining machine drawing-off disclosed in the utility model back zone servicing unit is applicable to the plane drawing-off or the V-arrangement drafting system of three roller ring spinning frames.Between the rear roller group that the middle roller group of middle top roller (9) and middle bottom roller (8) formation, back top roller (2) and back bottom roll (3) constitute, be provided with press-roller device (11), between middle roller group and last press-roller device (11), be provided with lower compression roller device (10).As shown in Figure 2, the plane drafting system of existing drafter, the drawing-off back zone is simple roller counter extensioin; As shown in Figure 3, when the utility model was used in the plane drawing-off, the back zone friction field had obvious enhancing, thereby the back zone fiber has been increased effective control, had shortened length of floating area, had to improve the good effect that bar is done, improved spinning quality.
As Fig. 4, shown in Figure 5, the described press-roller device (11) of going up is fixed on the pneumatic pressurizing cradle (1) by installing rack (4), and the hypomere of installing rack connects back shaft (12), and back shaft (12) end is pressure roller (5).Rotation-coupled can be adopted between pressure roller (5) and the back shaft (12),, also fixed connection can be adopted as bearing is installed.When adopting fixed connection, the pressure roller cross section should be a revolving body, or curved surface T shape, or curved surface is fan-shaped.
As Fig. 6, shown in Figure 7, described lower compression roller device (10) comprises a bar shaped depression bar (6), and its two ends are flush-mounted in the hole or groove of middle bottom roller slide (7).The cross section of depression bar (6) should be a revolving body, or curved surface T shape, or curved surface is fan-shaped.
For giving full play to good effect of the present utility model, last press-roller device (11) and lower compression roller device (10) should be suitable with respect to the position of reel cage and roller group.In the embodiment shown in the figures, pressure roller (5) is 22～39 millimeters with the horizontal centre-to-centre spacing of middle top roller; The vertical range of pressure roller (5) periphery incision inferius and reel cage divider lower plane is 26～34 millimeters.The vertical range at the last summit of depression bar (6) to middle bottom roller center is 10～16 millimeters; The horizontal range at the last summit of depression bar (6) to middle bottom roller center is 16～26 millimeters.
