Detailed Description
As shown in fig. 1, the yarn feeding device comprises a yarn guide mechanism and more than one yarn releasing unit; the paying-off unit comprises a speed regulating motor and a protofilament expansion cylinder 1; the speed regulating motor drives the protofilament to expand the 1 rotatory yarn that moves back of a section of thick bamboo, and the protofilament on the protofilament expands a section of thick bamboo 1 draws forth and is square backward through the guide agency direction along the protofilament expand a section of thick bamboo 1, plying and coiling 4 on the spooler aircraft nose.
The yarn guide mechanism comprises a yarn placing positioning wheel 3, a matched idler wheel 5 and a yarn receiving positioning wheel 8, the yarn placing positioning wheel 3 is perpendicular to an external common tangent of the protofilament expansion cylinder 1, and the yarn placing positioning wheel 3 and the yarn receiving positioning wheel 8 are arranged in a triangular mode through the matched idler wheel 5.
The paying-off unit is also provided with a tension detection mechanism, the tension detection mechanism is arranged between the yarn releasing positioning wheel 3 and the yarn receiving positioning wheel 8, and the tension detection mechanism comprises an angle sensor 2, a swing rod 7 and a movable roller 6; one end of the oscillating bar 7 is a positioning end, an angle sensor 2 is arranged on the positioning end, the positioning end is also the rotating axis of the oscillating bar 7, the other end of the oscillating bar 7 is a free end, a movable roller 6 is arranged on the free end, a signal input end of the angle sensor 2 detects the oscillating angle of the oscillating bar 7, and a signal output end is connected with a control end of a speed regulating motor and controls the rotating speed of the speed regulating motor.
Because the invention adopts the speed regulating motor to make the protofilament expansion cylinder 1 do active rotary motion, and then the protofilament actively and actively retreats outwards along the tangential direction of the protofilament expansion cylinder 1, the winder head 4 winds without generating the twisting phenomenon when axially retreating, thereby fundamentally eliminating the twisting problem and the tail yarn waste problem in the production process of the twistless roving.
Lead the walking direction of positive precursor through setting up three positioning wheel, and provide stable pulling force for the precursor, simple structure, preparation are easy, and owing to do not use the tensioner, avoid appearing elasticity strand and harm the phenomenon of precursor.
The automatic yarn breakage stopping function is realized by arranging the tension detection mechanism, in production, untwisted roving which is not loose or tight can be realized only when the outward retreating speed of the precursor on the precursor expansion cylinder 1 is equal to the winding speed of the precursor on the winder head 4, however, in reality, the winding speed of the precursor on the winder head 4 is constant, but the outward retreating speed of the precursor on the precursor expansion cylinder 1 is changed constantly and is neglected, so that the rotating speed of the precursor expansion cylinder 1 is regulated and controlled in real time, the movable roller 6 is designed to be placed on the precursor between the yarn releasing positioning wheel 3 and the yarn collecting positioning wheel 8, when the tension on the precursor is large, the supporting force borne by the movable roller 6 is large and can be supported, the rotating angle of the swing rod 7 is driven to be increased, and at the moment, the rotating speed of the precursor expansion cylinder 1 needs to be increased, and the yarn releasing is accelerated; when the tension on the protofilament is reduced, the supporting force on the movable roller 6 is small, and the movable roller falls back under the influence of self gravity, so that the oscillating bar 7 rotates towards the natural sagging direction, and at the moment, the rotating speed of the protofilament expansion cylinder 1 is slowed down, and the filament unwinding is slowed down; when the protofilament outward-withdrawing speed of the protofilament expansion cylinder 1 is consistent with the winding speed of the plied yarns on the winder head 4, the force applied to the movable roller 6 is constant, the swing rod 7 stays at an angle and does not move, and at the moment, the rotating speed of the protofilament expansion cylinder 1 does not need to be adjusted; therefore, the rotation angle of the oscillating bar 7 is detected by the angle sensor 2 and fed back to the controller of the speed regulating motor in time, so that the rotation speed of the speed regulating motor can be controlled in real time, and the tension of the protofilament is kept constant; the tension detection mechanism can also have the function of yarn breakage measurement, when yarn breakage occurs in a system of the glass fiber winder, namely, a protofilament loses tension, the oscillating bar 7 rapidly falls back to a vertical position, all speed regulating motors immediately realize the parking of the whole machine, and the protofilament expansion cylinder 1 has no inertia and continues to rotate to feed yarns; when the length of the winding reaches the fixed length, the speed regulating motor also realizes the stop of the whole machine.
The system can start the untwisted doubling production after the system is installed, if any one or more broken yarns occur in the production process, the angle sensor 2 can give a zero tension signal, and the system can be stopped instantly. After the winding length reaches the fixed length, the motor stops rotating immediately, and the phenomenon of continuously rotating and feeding yarn by inertia is avoided.
