Description
Technical field
The utility model relates to a kind of yarn tension control device of spinning engineering, relates in particular to the constant device of a kind of thread-tension.
Background technology
In spinning cotton wrapped filament process, due to cheese unwinding, from big to small, tension force also constantly changes diameter, causes the thread-tension produced unstable, and covered effect is poor.Therefore, tenslator becomes the key device in spinning process.For head it off, conventionally adopt at present following three kinds of methods:
1. gravity type yarn tension control device, i.e. a kind of device that adopts tension piece or spring loaded mode to control thread-tension.Because long filament can be vacillated between upper and lower tension pulley, during machine run, inevitably produce vibration, thread-tension is unstable.And the flyings that fine spining machine when spinning produces can enter between upper and lower tension pulley, and flyings twine and are clipped on long filament, when seriously hindering long filament and advancing, thread-tension can infinitely increase so that occur fracture.
2. adopt two tension balance rollers of upper and lower arranged parallel, upper tension roller is fixing to rotate, after the swingable adjustment in lower tension roller position is fixing, rotate, yarn is serpentine winding between two tension balance rollers, the tension force of yarn leans on the thread friction roller surface of coiled hair coiling and is dragged rotation and generation tension force, tension force does not change with unwinding tension when operation, if adjust tension force, to adjust the fixing position of lower tension roller, the size that changes the angle of contact of warp thread between two jockey pulleys is carried out adjustment of tonicity, tension force is not dynamically followed the tracks of, yarn tension is inhomogeneous, inconvenient operation.
3. adopt two tension balance rollers of upper and lower arranged parallel, upper tension roller is fixed and is had a motor to drive, lower tension roller is still the same with second method, this kind of method tension adjustment one is by changing the rotating speed of upper tension roller, initiatively send yarn, the 2nd, by changing the fixing position of lower tension roller, change yarn angle of contact, the total tension force of auxiliary increase and decrease, so still, exist tension force and control inaccuracy, tension force control and regulation scope is little, the defects such as inconvenient operation, cause that coiled hair tension force is inside and outside inconsistent on the same group, inconsistent mutually, outer perimeter error is large, directly have influence on fabric quality and the class of warp knitting machine, and driving efficiency, can not meet the technological requirement of weaving high-grade highly dense ultra-thin high-elasticity fabric.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail:
As shown in Figure 1, the constant device of the utility model thread-tension, comprises control roll 3, transmission mechanism 4 and front leather roller 5.Described front leather roller 5 is in transmission connection by described transmission mechanism 4 and described control roll 3.
The front leather roller 5 of the described constant device of thread-tension and front roller 6 Surface Contacts on fine spining machine.Long filament 1 is sandwiched between front roller 6 and front leather roller 5 through control roll 3, front roller 6 rotates, frictional force drives front leather roller 5 to rotate (, front roller and the linear resonance surface velocity of front leather roller are identical with the linear velocity of long filament) herein, and front leather roller 5 drives control roll 3 to rotate through transmission mechanism.According to long filament need of production, set the gearratio of transmission mechanism and the diameter of control roll 3, front leather roller 5 described in making is greater than 1 with the linear resonance surface velocity ratio of described control roll 3, realizes at control roll 3 and act on the tension force effect that is greater than 1 times to the long filament between front leather roller 5.Preferred embodiment is that described front leather roller is 1.08 with the linear resonance surface velocity ratio of described control roll, the long filament of 1.08 times of tension force of the constant device output of described thread-tension.
Linear velocity formula: V=D* π * n(meter per second) D-reference diameter (rice); N-rotating speed, (r/s, revolutions per second).
For realizing technique scheme, in a specific embodiment of the present utility model, described transmission mechanism 4 is the gear drive that the engagement of a plurality of (at least 2) gear forms.Described gear drive is fixed in holder 7.Described front leather roller 5 is fixedly connected with the gear of a side of gear drive by rotating shaft, described control roll 3 is fixedly connected with the gear of the opposite side of gear drive by rotating shaft, and described front leather roller 5 drives described control roll 3 to rotate by gear drive.
