The specific embodiment
Below in conjunction with above-mentioned accompanying drawing the embodiment of the invention is described in detail again.
As Fig. 1～shown in Figure 3, among the figure: 1-wallboard, 2-first drawing rollers, 3-bearing, No. two wire feed rollers of 4-, 5-spandex silk base, 6-silk base backstay, wire feed roller of 7-, No. three wire feed rollers of 8-, No. four wire feed rollers of 9-, 10-second drawing rollers, 11-output chain gear, 12-reel chain, 13-sprocket wheel, 14-input sprocket, 15-expansion tightening wheel, 16-short chain, 17-terylene thread, 18-pressure roller.
The doubler twister of band polyurethane filament feeding device, on the every joint wallboard 1 of doubler twister, be symmetrically installed with the first identical drawing rollers 2 of equal diameter, switched in opposite and rotating speed and second drawing rollers 10, first drawing rollers are identical with the second drawing rollers structure, terylene thread 17 is carried realization and is closed twisting through the pressure roller 18 and first or second drawing rollers, and this is the functional structure that former doubler twister has.
The present invention is provided with the spandex silk transport of second mate's symmetry and same structure between first drawing rollers 2 and second drawing rollers 10, this spandex silk transport is equidistant with adjacent first drawing rollers 2 or second drawing rollers 10 respectively, be installed in equally on the wallboard 1 by self-aligning bearing 3 supportings, this self-aligning bearing is located in the bearing block of fixing with wallboard, makes inside and outside axial limiting by bearing block omoplate and jump ring.
Wherein a secondary spandex silk transport comprises equal diameter, in the same way and a wire feed roller 7 and No. two wire feed rollers 4 of constant speed rotation, by the input sprocket 14 on the output chain gear 11 on second drawing rollers 10 and the wire feed roller 7 and have the chain wheel pair that the reel chain 12 of expansion tightening wheel 15 is formed, form another chain wheel pair by equal diameter sprocket wheel 13 on wire feed roller 7 and No. two wire feed rollers 4 and short chain 16 again and drive rotation;
Another secondary spandex silk transport comprises equal diameter, in the same way and No. three wire feed rollers 8 and No. four wire feed rollers 9 of constant speed rotation, form chain wheel pair by input sprocket 14 on the output chain gear 11 on first drawing rollers 2 and No. three wire feed rollers 8 and the reel chain 12 that has an expansion tightening wheel 15, form another chain wheel pair by equal diameter sprocket wheel 13 on No. three wire feed rollers 8 and No. four wire feed rollers 9 and short chain 16 again and drive rotation.
Second mate's spandex silk transport also is included in wire feed roller 7 and 4 of No. two wire feed rollers and No. three wire feed rollers 8 and No. four 9 of wire feed rollers and is equipped with spandex silk base 5, and a base backstay 6 is installed in each spandex silk base two side, guarantee silk base location, this base backstay be installed in the fixing fixed head separately of wallboard on, spandex silk base 5 after separately wire feed roller delivers into pressure roller 18 and drawing rollers with terylene thread 17 and close and realize twisting.The diameter of a wire feed roller of second mate's spandex silk transport, No. two wire feed rollers, No. three wire feed rollers and No. four wire feed rollers all equates, No. one the wire feed roller is identical with No. three wire feed laura structures, No. two the wire feed roller is identical with No. four wire feed laura structures, No. one the wire feed roller equates with the centre-to-centre spacing of No. four wire feed rollers that with No. two wire feed rollers, No. three wire feed rollers the size of centre-to-centre spacing will guarantee that spandex silk base does not drop.
The present invention can be applicable on the doubler twister of various models and specification, can be according to the technological requirement of client to the stretching of spandex silk, the drafting multiple of design wire feed roller and drawing rollers, draw ratio just, set by gearratio output chain gear 11 and input sprocket 14, just determined draw ratio between drawing rollers and the wire feed roller, this draw ratio must satisfy the requirement of spandex silk drawing process.The account form of drafting multiple is as follows:
Example: customer requirements is twisted with a spandex silk and a terylene thread and after closing on this type, and the drafting multiple of technological requirement spandex silk is about 3.5.
The linear velocity of the linear velocity of drafting multiple=drawing rollers/wire feed roller
Linear velocity=the n of drawing rollers
Drawing-off* 3.14 * d
Drawing-off÷ 1000 (M/min)
Linear velocity=the n of wire feed roller
Drawing-off* Z
Output÷ Z
Input* 3.14 * d
Wire feed÷ 1000 (M/min)
Wherein: n
Drawing-off: the rotating speed of drawing rollers (rev/min);
d
Drawing-off: the diameter phi 44 of drawing rollers;
Z
Output: the number of teeth of output chain gear: 16 teeth;
Z
Input: the number of teeth of input sprocket: 40 teeth;
d
Wire feed: the diameter phi 32 of wire feed roller;
This structure can satisfy customer requirements.
Ordinary circumstance, drafting multiple all can satisfy the user and make demands in 3～4 scopes.
