Abstract
The utility model relates to a V-shaped drafter used in textile spinning machine, belonging to a drafter used in textile spinning machine, wherein a rotary press roll device (2) is positioned between the middle roller set and the back roller set. The rotary press roll device is composed of a pivot staying (4), a support rack (5) and a press roll (3) positioned at the end of the pivot staying. The utility model greatly increases the enclosure arc length formed by the gauze on the surface of the back lower roller, dramatically reduces the length of the pelagic zone and exerts positive effect on enhancing the quality of yarn and reinforcing quality control.
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 weaving fine spining machine V-arrangement drafter.
" background technology " is in present textile industry, the V-arrangement drafter is a kind of drawing-off form commonly used, its characteristics are: raise at bottom roll center, back, back top roller moves behind bottom roll surface, back, and the back top roller and the back bottom roll line of centres and preceding, the middle bottom roller line of centres are formed an angle.Because the back bottom roll is raised, move behind the back top roller, make the sliver in the first break draft district that forms by it form one section grip hold arc on bottom roll surface, back, increased back bottom roll friction field intensity, and expansion forward, under the cooperation of rove turn, sliver forms long and narrow V font in the back area draft process, cooperate with less back zone ratch, length of floating area is shortened, improved the tightness of feeding proparea sliver in the draw zone, it is out of control to prevent that indent from appearring in the cushion rubber middle part, has strengthened the control to fiber movement.But, because raise at the rear roller center, make middle roller jaw place generate a reverse arc of contact, the friction field of front portion, back zone is expanded backward, and floating fiber shifts to an earlier date speed change, has increased additional irregular that drafting wave produced.When particularly current, middle top roller used hypsokinesis greatly, this phenomenon was more serious.
" summary of the invention " the purpose of this utility model promptly is to provide a kind of novel weaving fine spining machine V-arrangement drafter, to overcome the above-mentioned shortcoming of existing V-arrangement drafter, reach and increase to surround arc length, reduce length of floating area, eliminate the reverse arc of contact at middle roller jaw place, improve spinning quality and the purpose of quality control ability.
Weaving fine spining machine V-arrangement drafter disclosed in the utility model, comprise the front roller group that is installed on pneumatic pressurizing cradle (1) by front upper roller (6) and preceding bottom roll (7) formation, middle roller group by middle top roller (8) and middle bottom roller (9) formation, rear roller group by back top roller (11) and back bottom roll (10) formation, it is characterized in that, between middle roller group and rear roller group, be provided with and rotate press-roller device (2), so-called rotation press-roller device by back shaft (4) and the pressure roller (3) that is used for that back shaft is fixed in the installing rack (5) of pneumatic pressurizing cradle and is installed in the back shaft end form; Connect for rotatable between pressure roller (3) and the back shaft.
Weaving fine spining machine V-arrangement drafter disclosed in the utility model, 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 greatly, and obviously reduced length of floating area, eliminated the reverse arc of contact at middle roller jaw place, to improving spinning quality and the ability of quality control being had good effect.
" description of drawings " accompanying drawing discloses specific embodiment of the utility model, wherein:
Fig. 1, the location diagram of the utility model and pneumatic pressurizing cradle;
Fig. 2, the utility model fundamental diagram;
Fig. 3 rotates the press-roller device structural representation;
Fig. 4, A-A is to view.
" specific embodiment " as depicted in figs. 1 and 2, weaving fine spining machine V-arrangement drafter disclosed in the utility model comprises the front roller group, middle roller group and the rear roller group that are installed on the pneumatic pressurizing cradle (1).So-called front roller group is meant front upper roller (6) and preceding bottom roll (7); So-called middle roller group is meant middle top roller (8) and middle bottom roller (9); So-called rear roller group is meant back top roller (11) and back bottom roll (10).The utility model is provided with between middle roller group and back bottom roll and rotates press-roller device (2).
As shown in Figure 3 and Figure 4, rotate press-roller device and comprise back shaft (4) and be positioned in the middle part of the back shaft, be used for back shaft is fixed in the installing rack (5) of pneumatic pressurizing cradle, and the pressure roller (3) that is installed in the back shaft both ends.Should adopt rotatable the connection between pressure roller (3) and the back shaft, as bearing is installed, perhaps between is directly arranged ball or needle roller.In the embodiment shown in the figures, the external diameter of pressure roller (3) is 6～18 millimeters.
For giving full play to good effect of the present utility model, rotating press-roller device should be suitable with respect to the position of reel cage and roller group.In the embodiment shown in the figures, the centre of location of pressure roller (3) and the centre of location of middle top roller, both horizontal direction centre-to-centre spacing are 17～23 millimeters, vertical direction centre-to-centre spacing is 6.5～12.5 millimeters; Distance from the last end face of installing rack (5) to pressure roller (3) periphery incision inferius is 26～34 millimeters.
Weaving fine spining machine V-arrangement drafter disclosed in the utility model, owing between middle roller group and rear roller group, the rotation press-roller device is set, the angle of contact that forms on the rear roller surface is increased to about 130 ° by original about 82 °, thereby make the encirclement arc length be increased to 29 millimeters by 18 millimeters, and length of floating area reduces to 22.5 millimeters by original 35 millimeters, and eliminated the reverse arc of contact at middle roller jaw place, the ability to quality control has a significant effect in spinning quality and the technical process to improving.
Claims (2)
1, a kind of weaving fine spining machine V-arrangement drafter, comprise the front roller group that is installed on pneumatic pressurizing cradle (1) by front upper roller (6) and preceding bottom roll (7) formation, middle roller group by middle top roller (8) and middle bottom roller (9) formation, rear roller group by back top roller (11) and back bottom roll (10) formation, it is characterized in that, between middle roller group and rear roller group, be provided with and rotate press-roller device (2), so-called rotation press-roller device by fulcrum support (4) and the pressure roller (3) that is used for that back shaft is fixed in the installing rack (5) of pneumatic pressurizing cradle and is installed in the back shaft end form; Connect for rotatable between pressure roller (3) and the back shaft.
