Abstract
The present invention relates to thread feeding speed stabilizing device and method for double twister roller. The method of the present invention includes conveying actively the ply thread with the clamping upper roller and lower roller; and ensuring the excellent formation and density of the yarn with the torsion spring compensator, so as to stabilize the thread feeding speed and thread feeding speed of roller and raise the quality of the yarn. The device includes one circular upper metal roller and one circular lower rubber roller installed in pair to form one clamping roller, one torsion spring compensator and one self-locking mechanism of rocker capable of pressing or relieving the upper and the lower rollers.
Description
Technical field
The present invention relates to a kind of device and method of constant two-for-one twister roller line sending speed.
Technical background
Overfeeding roller in the actual use of two-for-one twister has two kinds of forms at present: first kind of disc type overfeeding roller, this overfeeding roller mainly is made up of two disks, about the inboard of two disks, half spheroidal thrust is respectively arranged, the semicircle of two disks is spherical, and thrust is interlaced with each other is being connected.On-stream, yarn is being driven along winding raod by the thrust surface and is directly advancing, along with reciprocal about the fro guiding-yarn device, the diameter of take-up package changes from small to big, move back and separate bobbin from large to small, and multifactorial influence such as Taper Pipe itself, fluctuation can appear in the tension force of yarn.When the frictional force on thrust surface is not enough, can make yarn slippage in the overfeeding roller.Second kind of double-roll type overfeeding roller, for heavy two-for-one twister, because yarn tension is very big, the control ability of disc type overfeeding roller is not enough, therefore will use double-roll type overfeeding roller.Double-roll type overfeeding roller has bigger control to strand, but along with thread-carrier back and forth and the fluctuation of winding speed, strand still has some slippages on two rollers surface.The take-up package of former two-for-one twister is by the winding off spindle frictional drive, inevitable exist because of the skidding of tapering, take-up package and the friction pulley of take-up package, guide is traversed, reach the influence of moulding yarn tube size, cause and batch the strand winding tension, move back the instability of separating outer tension force of tension force, air ring and air ring internal tension, the instability of strand speed is batched in influence simultaneously, causes to produce the higher limitation of yarn twist irregularity.
In recent years, since more and more higher to the requirement of strand, owing to be subjected to present two-for-one twister structural limitations, concerning two-for-one twister, depend merely on and improve the parts machining accuracy, the uneven twist of strand is further reduced.Up to now, also do not have a kind of two-for-one twister can guarantee to batch the strand constant airspeed, make the twist irregularity rate very stable.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned prior art defective, and a kind of device and method of constant two-for-one twister roller line sending speed is provided, and the strand twisting unevenness of producing is low, and the strand quality is good.
The technical solution adopted in the present invention is such: the overfeeding roller of two-for-one twister is made up of a metal bottom roll and a rubber top roller.Strand is through behind the upper and lower roller nip, and the guiding coiler device is because the overfeeding roller is shorter with the distance of reeling, the influence that the concentric reducer of Taper Pipe and fro guiding-yarn device are caused, install a torque spring compensator additional, reach the constant of coiling tension, guarantee to batch the moulding and the line density of pipe.By the clipping transmission of last bottom roll, controlled the constant of two-for-one twister roller line sending speed, thereby the twist irregularity rate of strand is reduced.
Description of drawings
Fig. 1 is the process flow diagram of a kind of constant two-for-one twister roller line sending speed of the present invention and the structural representation of roller
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in the figure, a kind of apparatus and method of controlling two-for-one twister roller line sending constant airspeed, strand 3 is by top roller 6 and bottom roll 5 bites, its middle bottom roller 5 is a driving wheel, roller line sending speed is controlled by the diameter and the rotating speed of bottom roll, and the chucking power between top roller 6 and the bottom roll 5 provides by the pulling force of extension spring 8; Strand again by torque spring compensator 4, be rolled onto and batch above the bobbin 1.Its middle top roller 6 and extension spring 8, roller support 7, rocking arm 9 are mounted on the installing plate 10 by routine.
Claims (3)
1. the method for a constant two-for-one twister roller line sending speed is characterized in that: strand is through the bite of last bottom roll, and by the constant rotation of last bottom roll, strand is initiatively transmitted by the chucking power of last bottom roll, and line sending speed is determined by bottom roll diameter and rotating speed; Again by the torque spring compensator, regulate the coiling tension of strand on the bobbin by the torque spring compensator, make and batch that pipe is gone up the yarn moulding and line density is good; Thereby stablize strand tension force and roller line sending speed, reduce the strand twist irregularity.
2. the device of constant two-for-one twister roller line sending speed, it is characterized in that: the cylindrical rubber top roller mounted in pairing mode of the cylindrical metal bottom roll of an active rotation and a passive rotation, last bottom roll is in and presses or disengaged condition, its middle bottom roller is installed on the two-for-one twister roller shaft, top roller is installed on the top roller support, and the top roller support is installed on the installing plate; The extension spring that is installed on the installing plate is connected with the top roller support; The rocking arm that is installed on the installing plate is attached on the top roller support; Being installed in torque spring compensator on the installing plate is in bottom roll and batches between the bobbin.
3. the device of constant two-for-one twister roller line sending speed according to claim 2 is characterized in that: after last bottom roll had been installed, both combinations had just formed clipping roller device; During operate as normal, last bottom roll compresses, and during non-normal working, last bottom roll disengagement does not contact.
