The real-time regulator of a kind of thread-tension
Technical field
The utility model belongs to spinning equipments technical field, relates to a kind of tension adjusting device, particularly relates to the real-time regulator of a kind of core-spun yarn core thread tension.
Background technology
Cladded yarn and wrapped yarn are all with certain long filament for yarn core, the fiber of the coated different qualities in outside, but coated outside cladded yarn be staple fibre, wrapped yarn is covered filament then.Heart yarn can select polyamide fibre, terylene, spandex etc., and for elastic force composite yarn, what use was maximum at present is spandex filament.The outer wrapping fiber of spandex core-spun yarn can be the natural fabrics such as cotton, fiber crops, silk, hair, also can be acrylic fibers or other purely to spin and the chemical fibre of blending, heart yarn spandex provides excellent elasticity, and outer wrapping fiber provides the surface property of different-style.The fabric sofetening be made into this yarn, comfortable, next to the skin, freedom of motion, can fully show human body natural U.S., therefore be popular, and is kind more popular both at home and abroad at present.
Cladded yarn must encase yarn core spandex thread completely, the formation if spandex thread is exposed " dew core " phenomenon, the dyeing of later process will be affected, and in process afterwards, inevitably make spandex thread directly and between parts too much rub, cause spandex thread surprisingly to rupture, produce hollow inclusion triaxial strain gauge, yarn is followed the string, and wrinkling on cloth cover, form fault.So long filament will be made in spinning process to be distributed in the central part of yarn as far as possible, avoid being exposed.Research finds, spin coated complete uniform cladded yarn, suffered by core silk, tension force should be larger than outer wrapping fiber, and front roller nip place outer wrapping fiber output speed should be large compared with core silk, and can rotate around core silk, and the tension force of core silk will keep stable as far as possible.
During weaving spandex core-spun yarn, in fine spining machine Suspended Spindle for Roving bottom, one group of conveying cylinder need be installed, spandex filament bobbin is placed on conveying cylinder, the linear velocity of conveying cylinder, lower than the linear velocity of front roller, makes spandex filament obtain preliminary draft, and to control its percentage elongation be definite value, make spandex filament obtain certain tension force simultaneously, afterwards, spandex filament rubber roll rear collector before godet roller feeding fine spining machine combines with the yarn of rove after drawing-off, and forms spandex core-spun yarn through twisting.
Utilize the tension force of aforesaid way institute spun core-spun yarn core silk mainly from the speed difference between front roller and conveying cylinder, core thread tension is unstable, be subject to the impact of the factor such as the debatching of spandex bobbin and other parts frictions, the covered effect of core silk had an impact, finally can affect the quality of cladded yarn.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tension adjusting device, particularly the real-time regulator of a kind of core-spun yarn core thread tension.
The real-time regulator of a kind of thread-tension of the present utility model, comprise wire winding rod, movable disc, fixed disc, conducting wire pole, weight, rolling bearing, described wire winding rod one end and described fixed disc are connected and fixed, the other end is connected with described movable disc 2 by described rolling bearing 8, described movable disc axle center is provided with connecting axle, described connecting axle is by the other end of described rolling bearing kink at described wire winding rod, described movable disc by described rolling bearing around described wire winding rod flexible rotating, described movable disc is provided with toroidal first through hole run through, described fixed disc is provided with toroidal second through hole run through, the long filament that unwinding is got off from bobbin is through described second through hole, axially be wrapped on described wire winding rod, and through described first through hole, after conducting wire pole, enter front roller and staple fibre and close twisting, the outer ledge of described movable disc is carved with groove, ine wound is in described groove, described weight is hung with below described cord.Movable disc can be driven to rotate by the lifting of described weight, the winding number of turns of long filament on described wire winding rod and angle be changed, changes the size of frictional force between described long filament and described wire winding rod, thus make the tension force of described long filament keep stable.When thread-tension between described first through hole and described conducting wire pole reduces, weight position can decline, because described first through hole is in the eccentric position of described movable disc, when weight position declines, cord can pull movable disc to rotate, and the horizontal level of the first through hole reduces, and the winding angle of long filament on described wire winding rod increases, therefore the frictional force between long filament and wire winding rod can increase, and the tension force of long filament is increased; Otherwise, when thread-tension increases, under tension, long filament can drive movable disc counter-rotation, and the horizontal level of the first through hole raises, and the winding angle of long filament on described wire winding rod is diminished, therefore the frictional force between long filament and wire winding rod can reduce, and the tension force of long filament can reduce.
As preferred technical scheme:
The real-time regulator of a kind of thread-tension as above, described wire winding rod smooth surface, length is 4 ~ 8cm, and diameter is 2 ~ 3cm.Wire winding rod smooth surface can reduce the rubbing action of wire winding rod to long filament, avoids sanding or the broken end of long filament.
The real-time regulator of a kind of thread-tension as above, the diameter of described movable disc and described fixed disc and thickness are all equal.
The real-time regulator of a kind of thread-tension as above, the diameter of described movable disc and fixed disc is 6 ~ 8cm, and thickness is 2 ~ 3mm.
The real-time regulator of a kind of thread-tension as above, the surface of described first through hole and described second through hole is ceramic material.Through hole employing ceramic material can effectively reduce the friction between long filament and through hole.
The real-time regulator of a kind of thread-tension as above, described first through hole is identical with the diameter of described second through hole, is 2 ~ 3mm.
The real-time regulator of a kind of thread-tension as above, the distance between the described second through hole center of circle and the described fixed disc center of circle is 5 ~ 7cm, and the distance between the center of circle of described first through hole and the described movable disc center of circle is 5 ~ 7cm.
