Detailed description of the invention
For making those of ordinary skill in the art clearly understand the purpose of this utility model, technical scheme and advantage, below in conjunction with drawings and Examples, the utility model is further elaborated.
Shown in figure 1, in a kind of embodiment of the present utility model, this single yarn tension control device includes: a pedestal 1, pretensioner 4, be arranged on pedestal 1 main roller 31 for winding yarn 3 and be arranged on pedestal 1 is arranged at the divergence type roller 32 for winding yarn 3 on pedestal 1, wherein, a drive unit (not shown in FIG.) for driving pretensioner 4 to rotate is provided with in pretensioner 4.
In warping process, when yarn 3 is after unwinding out spool, drive unit drives pretensioner 4 to rotate, thus drive yarn 3 to move, reduce the friction of yarn 3 stressed, yarn 3 more successively through main roller 31 and divergence type roller 32, and according to the tensile requirements of different yarns 3, be wound around a fixing turn between the two, out from one end of divergence type roller 32 at this finally.When warping machines stops, yarn 3 can rely on pretensioner 4 active type rotate and be subject to fixing uniformly tension force, there will not be the phenomenon of the loose yarn that skids.This single yarn tension control device, makes every one thread uniform stressed by the aggressive drive manner of pretensioner 4, and the stressed effect thus arrival minimizing yarn 3 rubs, improves the quality of yarn 3.
Preferably, in embodiments more of the present utility model, pretensioner 4 includes a rotatable packing ring post 41 and at least two and is sheathed on packing ring post 41 for controlling the washer plate 42 of the stressed size of yarn 3, drive unit is located within packing ring post 41, rotated by drive unit actuator pad loop pillar 41, drive unit can be motor.
In warping process, when yarn 3 is after unwinding out spool, through pretensioner 4, drive unit actuator pad loop pillar 41 rotates, thus drives yarn 3 to move, and the friction reducing yarn 3 is stressed, yarn 3 is more successively through main roller 31 and divergence type roller 32, and according to the tensile requirements of different yarns 3, be wound around a fixing turn between the two at this, out from one end of divergence type roller 32 finally.When warping machines stops, yarn 3 can rely on packing ring post 41 active type rotate and be subject to fixing uniformly tension force, there will not be the phenomenon of the loose yarn that skids.Because this pretensioner 4 includes at least two cover washer plates 42, yarn 3, when pretensioner 4, passes, can prevent the yarn 3 relaxed to fly out pretensioner 4 between two cover washer plates 42.
Preferably, in embodiments more of the present utility model, more than two covers of quantity of washer plate 42, concrete, pretensioner 4 changes tension force suffered by yarn 3 by the quantity adjusting washer plate 42, and the tension value that yarn 3 is set is between 5 kilograms to 24 kilograms.
Preferably, in embodiments more of the present utility model, the surface of washer plate 42 is formed with a matt plating material layers, because matt plating material layers smooth surface, can ensure the unimpeded mistake of yarn flow and not contaminated.
Preferably, in embodiments more of the present utility model, pretensioner 4 also includes a bow 43, and one end of bow 43 is connected to the top of packing ring post 41, and the other end is connected to pedestal 1.Quantity due to washer plate 42 is change, and the washer plate 42 do not used can forward non-working side to by bow 43, eliminates the operation because adding or reduce washer plate 42 and provision for disengagement.
Preferably, in embodiments more of the present utility model, this single yarn tension control device also includes an air ring dish 2, and air ring dish 2 center is provided with the thread guide eyelet 21 that is connected to pedestal 1.
In warping process, yarn 3, can first by the thread guide eyelet 21 at air ring dish 2 center out after unwinding out spool, then to pretensioner 4.Air ring dish 2 can by the filoplume near yarn 3, disconnected fine isolation, prevents filoplume, to be disconnectedly finely adsorbed in pretensioner 4 because of electrostatic, cause yarn 3 sanding or cause yarn 3 unbalance stress.Meanwhile, air ring dish 2 can make the air ring formed during yarn 3 unwinding break, thus stablizes the tension force of yarn 3.
Preferably, in embodiments more of the present utility model, the ceramic material that thread guide eyelet 21 adopts hardness higher processes, and makes thread guide eyelet 21 have level and smooth inwall passage, when can ensure that yarn 3 passes through out from thread guide eyelet 21, does not sustain damage because of friction.
Preferably, in embodiments more of the present utility model, the diameter of main roller 31 is 31.8mm, and its surface is formed with a matt plating material layers, because matt plating material layers smooth surface, can ensure the unimpeded mistake of yarn flow and not contaminated.
Preferably, in embodiments more of the present utility model, main roller 31 is built-in with hysteresis brake and the impulse generator of direct current 12V/1.2W, so, because this hysteresis brake and impulse generator are the hysteresis characteristics of application special magnet, the braking moment produced by noncontact structure, therefore there is not Wear parts, can obtain yarn 3 tension force of long-time stable, and heating seldom, power consumption is lower.In addition, when there is the situation of broken filament in yarn 3, main roller 31 is subject to disconnected fine frictional force reason and produces revolution, built-in impulse generator can detect main roller 31 revolution, therefore by the pulse recording monitoring arrangement in outer setting, the defective eigenpairs etc. of yarn 3 can be detected.
Preferably, in embodiments more of the present utility model, the diameter of divergence type roller 32 is 25mm, and its surface is formed with a matt plating material layers, because matt plating material layers smooth surface, can ensure the unimpeded mistake of yarn flow and not contaminated.
Divergence type roller 32 and main roller 31 are arranged at certain intervals, yarn 3 moves to divergence type roller 32 from main roller 31, can the coefficient of friction of root Ju different yarns 3, use the different winding number of turns, thus ensure that yarn 3 does not skid on roller, prevent friction fluffing, ensure that yarn 3 moves together with roller, the tension force that simultaneously yarn 3 can be kept uniform and stable.
Preferably, in embodiments more of the present utility model, divergence type roller 32 center is provided with a screw rod that can move left and right 321.
When yarn 3 is wound around mobile on two rollers, makes divergence type roller 32 have slight moving left and right to adjust different angles by moving left and right screw rod 321, thus yarn 3 even laminating on two rollers is opened, can not be wound into together.Do not come in contact between yarn 3 and yarn 3, just can operate on smooth flow ground, thus reduce yarn 3 because of the phenomenon causing broken filament fluffing that rubs.
During power failure, by reserve battery, hysteresis brake is powered, main roller 31 can be suppressed to exceed stroke, prevent the lax of yarn.
The foregoing is only preferred embodiment of the present utility model, but not any pro forma restriction is done to the utility model.Those skilled in the art can impose various equivalent change and improvement on the basis of above-described embodiment, and all equivalent variations of doing in right or modification, all should fall within protection domain of the present utility model.
