Abstract
The invention discloses an overfeeding device driven by a stepping motor. The overfeeding device driven by the stepping motor comprises the stepping motor (1) and an overfeeding wheel (2) driven by the stepping motor (1), wherein the rotating speed of the stepping motor (1) is controlled by pulse signals output by a control system (6). The overfeeding device driven by the stepping motor is characterized in that the stepping motor (1) and the overfeeding wheel (2) are fixedly connected in a coaxial mode, and a yarn friction area (5) is arranged on the outer surface of the overfeeding wheel (2). The overfeeding device driven by the stepping motor has the advantages that the stepping motor (1) and the overfeeding device are matched to control the crimp tension of yarns, and then control of density and hardness of each thickness layer of a yarn package is achieved; the automation degree is high, and the structure is simple.
Description
Technical field
The invention belongs to field of textile machinery, relate in particular to a kind of super-feeding device being applied on doubler or slack winder.
Background technology
Doubler or slack winder are all the equipment that reel for yarn can be coiled into the spinning link of fixedly package, the yarn wound packages of these two kinds of equipment windings can directly be put into dye vat and dye, but often because the inner thick layer density of yarn package is harder, outer thick layer density is less softer, dyeing there will be inhomogeneous phenomenon, mostly this kind of phenomenon is because same package adopts due to basically identical yarn winding tension, also do not have at present a kind of technology can well solve this difficult problem, conventionally the tension force that removes to regulate yarn tensioner of just thinking, but this kind of method obviously can not evenly be controlled tension variation, and can not apply at large-scale production process, limitation is larger.
Summary of the invention
The invention solves an above-mentioned difficult problem, a kind of super-feeding device that can evenly adjust curling tension force is provided.
Technical scheme of the present invention is to provide a kind of employing stepper motor and drives super-feeding device, comprise: stepping motor and being taken turns by described stepper motor driven overfeeding, described stepping motor is controlled its rotating speed by control system output pulse signal, it is characterized in that, described stepping motor is coaxially fixedly connected with described overfeeding wheel, and described overfeeding wheel outer surface is provided with thread friction district.
As preferred version, described overfeeding wheel is cylindrical housings, and one end is fixed on described stepping motor axle drive shaft and follows described stepping motor rotation, and the described overfeeding wheel other end is provided with the rib that diameter is greater than cylinder diameter.
As preferred version, described overfeeding wheel top is provided with two spaced yarn levers, and described yarn archives are parallel with described overfeeding wheel axis.
As preferred version, within the scope of the duration of setting, described stepping motor rotating speed evenly increases with to setting rotating speed maxim from setting rotating speed minimum value, and described setting-up time is the time of the complete cylinder yarn of reeling.
The invention has the beneficial effects as follows: adopt stepping motor and super-feeding device to coordinate the control realizing yarn crimp tension force, thereby reach the control to each thick layer density and hardness of yarn package.It is high that the present invention has degree of automation, advantages of simple structure and simple.
Accompanying drawing explanation

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the super-feeding device that a kind of employing stepping motor of the present invention (1) drives, the stepping motor (1) that is positioned at the left side is taken turns (2) with cylindrical overfeeding and is fixedly connected with, stepping motor (1) rotating shaft is coaxial with overfeeding wheel (2), overfeeding wheel (2) can rotate freely, the parallel side of being located thereon of (2) axis is provided with two levers (3) with overfeeding wheel, in the middle of overfeeding wheel, be provided with frictional belt (5), another side is provided with the rib (4) larger than frictional belt (5) diameter, and rib (4) is for stopping yarn (8) landing from overfeeding wheel (2).
Control system (6) output pulse signal control step motor (1) rotating speed, within the time of a complete cylinder yarn of reeling, the rotating speed of stepping motor (1) evenly increases in the speed range of setting, and overfeeding wheel (2) synchronously rotates with stepping motor (1).
When the present invention works, as shown in Figure 2, overfeeding wheel (2) clickwise, yarn (8) is wound around to 1 circle to 5 circles from overfeeding wheel (2) front lower place along overfeeding Lun frictional belt (5) cw, from overfeeding wheel (2) front upper place, arrive lever (3), by yarn (8) around lever (3) rear to arranging on the lower around the lever the place ahead to top setting, final thread (8) enters wrapping range.The overfeeding wheel (2) rotating due to friction force effect drive winding direction with it identical yarn (8) rotate up, yarn (8) is owing to being driven and having some tension by the winding mechanism of top, this Tensity size is influential to the density of cylinder yarn, if yarn tension is consistent, curling barrel yarn there will be the outer hard soft phenomenon of internal layer, in the present embodiment, stepping motor (1) drives overfeeding wheel (2) rotative speed within the time of a curling complete cylinder yarn constantly to increase, and then enter at any time yarn crimp tension force and constantly reduce, meet the consistent requirement of cylinder yarn ectonexine soft or hard.
The number of turns that above-mentioned yarn (8) is wound around overfeeding wheel (2) is subject to the factor impacts such as the thickness, raw material type, humiture of yarn (8).
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
