Spandex is the abbreviation of polyurethane fibre, is a kind of elastomer, when producing spandex, for clot tension, Number on cylinder, breaking strength, elongation at break, forming degree, oily adhesion amount, elastic recovery rate etc. will be paid special attention to, this problem is straight Influence braiding is connect, more to be noticed with knitting production facecloth especially.Spandex when in use, under yarn will be unwound from spinning cake first Come, then merges subsequently into coiled hair or with other yarns by various filar guides, drawing rollers and be made into packet yarn, covering yarn etc. Product, but during unwinding yarn, the variation of any one factor can all cause spandex thread unexpectedly to extend, and cause tension Fluctuation, also directly affects the thickness of the spandex thread, causes the dry unevenness of item, and woven cloth cover has " thick-thin-strip " etc. abnormal, causes product Matter decline, direct economic loss.
【Utility model content】
To overcome defect existing for existing equipment, the utility model lies in that providing a kind of spandex unwinding device.
The utility model is realized in this way:A kind of spandex unwinding device, including in the past according to the spandex yarn direction of motion Unwinding roller, drawing rollers group and the winding roller group set gradually after;The unwinding roller is vertically arranged, and a spandex thread Cake is tightly attached to unwinding roller setting;The drawing rollers group includes two drawing rollers that are setting up and down and relatively rotating with respect to each other;Institute Stating winding roller group includes an active winding roller and a driven wind up roller setting up and down.
It preferably, further include that a fixing axle and one hang yarn count arm, the fixing axle is vertically arranged;The extension yarn count arm includes One rotary components, transmission arm and a fixation member;The rotary components include a rotating cylinder and a bearing, and the rotating cylinder is rotationally It is fixedly connected on transmission arm, the spandex spinning cake is sheathed on rotating cylinder, and the bearing is set to inside rotating cylinder;The fixation member It is paid by screw rod lock in fixing axle, having an annular groove and sleeve inside the fixation member, a torsion spring set is set on casing And it is fixed in the annular groove.
Preferably, further include two tension sensors, a tension sensor be set to unwinding roller and drawing rollers group it Between, another tension sensor is set between drawing rollers group and winding roller group.
Preferably, the upper and lower part of the driven wind up roller is fixedly connected with a spring respectively, and the driven wind up Roller can move down setting under the action of two springs.
The utility model has the advantage of:Spandex thread cake can be made to realize unwinding well, test tensile wave in unwinding Emotionally condition provides valuable reference information to downstream warping, weaving, packet yarn client to select optimal drawing-off parameter;It is replacing It only needs to sample when raw material to test, so that it may suitable weaving tension etc. is selected, after avoiding spandex raw material from going up machine by the gross, then slowly Slow debugging, caused by product quality decline, be raw material producer and down-stream enterprise's save the cost.
【Detailed description of the invention】
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a kind of overall diagram of spandex unwinding device of the utility model.
Fig. 2 is the schematic diagram of winding roller group in the utility model.
Fig. 3 is the structural schematic diagram that yarn count arm is hung in the utility model.
【Specific embodiment】
A kind of spandex unwinding device 100 referring to FIG. 1-2, including from front to back successively according to 1 direction of motion of spandex yarn The unwinding roller 2 of setting, drawing rollers group 3, winding roller group 4 further include that a fixing axle 5, one hangs yarn count arm 6 and two tension biography Sensor 7;The unwinding roller 2 is vertically arranged, and a spandex spinning cake 10 is tightly attached to the setting of unwinding roller 2;The drawing rollers group 3 Including two drawing rollers 31 that are setting up and down and relatively rotating with respect to each other;The winding roller group 4 includes an active setting up and down Winding roller 41 and a driven wind up roller 42;When in running order, spandex spinning cake 10 is close to the rotation of unwinding roller 2 and is set It sets, and the spandex yarn 1 on spandex spinning cake 10 bypasses unwinding roller 2, is wound in winding roller under the gripping of drawing rollers group 3 In group 4.The upper and lower part of the driven wind up roller 42 is fixedly connected with a spring 8 respectively, and the driven wind up roller 42 Setting can be moved down under the action of two spring 8.One tension sensor 7 be set to unwinding roller 2 and drawing rollers group 3 it Between, another tension sensor 7 is set between drawing rollers group 3 and winding roller group 4.
Referring again to Fig. 1 and Fig. 3, the fixing axle 5 is vertically arranged;The extension yarn count arm 6 includes a rotary components 61, passes Swing arm 62 and a fixation member 63;The rotary components 61 include a rotating cylinder 611 and a bearing 612, and the rotating cylinder 611 can be rotated Ground is fixedly connected on transmission arm 62, and the spandex spinning cake 10 is sheathed on rotating cylinder 611, and the bearing 612 is set in rotating cylinder 611 Portion;The fixation member 63 is paid by screw rod lock (not shown) in fixing axle 5, has an annular groove inside the fixation member 63 631 and sleeve 632, a torsional spring (not shown) be sheathed on casing 632 and be fixed in the annular groove 631, which passes through Fixation member 63, transmission arm 62 drive spandex spinning cake 10 to be tightly attached to the setting of unwinding roller 2;
The major function of each component is as follows:
Unwinding roller 2:There is Serve Motor Control, servo motor drives vertical direction unwinding roller 2 to rotate, moves back by belt It is surface plated resin material around roller 2, inside is steel column material;
Hang yarn count arm 6:Fixed spandex yarn 1, and the mechanism that spandex spinning cake 10 can be made to rotate;
Drawing rollers group 3:By Serve Motor Control, size is identical, and direction of rotation leads on the contrary, for holding spandex yarn 1 It crosses and forms speed difference with unwinding roller 2, to realize the stretching of spandex spinning cake 10.
Active winding roller 41:There is Serve Motor Control, stretching can be realized by speed difference,
Driven wind up roller 42:It is contacted with active winding roller 41, passive rotation, for winding the spandex yarn brought 1, and as the spandex thread of winding is more and more, driven wind up roller 42 can move down.
Two tension sensors 7:The tension data of the spandex yarn 1 real-time monitored is transmitted to controller, controller is logical Analysis tension data is crossed, to analyze the fluctuation situation of tension, the stability of tension when being unwound to reference spandex spinning cake 10.
Spandex thread cake can be made to realize unwinding well, tension fluctuation situation is tested in unwinding, to select optimal lead Parameter is stretched, provides valuable reference information to downstream warping, weaving, packet yarn client;It only needs to sample when replacing raw material to do reality Test, so that it may select suitable weaving tension etc., avoid spandex raw material by the gross after upper machine, then slowly debug, caused by product matter Amount decline is raw material producer and down-stream enterprise's save the cost.
Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should Cover in the scope of the claimed protection of the utility model.
