Description

The synchronous automatic control device of a kind of yarn tension

Technical field

The utility model relates to the synchronous automatic control device of a kind of yarn tension of textile machine.

Background technology

Yarn tension between warping in itemize warping sizing machine coiling and the drying room is controlled through the XP1 toric transmission at present, and the operator carries out manual shift according to on-site actual situations in the winding work process.When the speed of a motor vehicle changes, also need do suitable adjustment, since operational extremely inconvenient, often cause winding tension uneven, thereby directly influenced rolling density, and winding quality can not get guarantee.

The utility model content

The technical matters that the utility model will solve provides the synchronous automatic control device of a kind of yarn tension, it can keep permanent tension force in the yarn winding process, thus ensured yarn around winding quality.

For solving the problems of the technologies described above; The synchronous automatic control device of a kind of yarn tension of the utility model; It contains drying room motor, coiling motor; Also contain tension bracket mechanism, synchrotransmitter, Programmable Logic Controller, drying room frequency converter, coiling frequency converter, rotary encoder; Tension bracket mechanism is made up of support, four sprocket wheels, two transmission shafts, jockey pulley, two chains, and two transmission shafts are separately positioned on the internal upper part and the interior bottom of support, and the both ends of two transmission shafts are provided with described four sprocket wheels respectively; The upper and lower sprocket wheel that is positioned at the support both sides links through described two chains respectively; The both ends of jockey pulley are arranged on respectively on these two chains, and the spindle nose and the synchrotransmitter of an axle in said two transmission shafts link, and the mouth of synchrotransmitter is connected with the input end of Programmable Logic Controller through lead; The rotating shaft of rotary encoder and coiling motor links; The mouth of rotary encoder is connected with the input end of Programmable Logic Controller through lead, and the mouth of Programmable Logic Controller is connected with the input end of drying room frequency converter with the coiling frequency converter respectively through lead, and the sensible lead of the mouth of drying room frequency converter and coiling frequency converter is connected with the coiling motor with the drying room motor respectively.

Because above-mentioned control setup adopts Programmable Logic Controller as central processing controller; When the drying room motor was asynchronous with the coiling motor, yarn made jockey pulley do to go up or move down, and jockey pulley passes to synchrotransmitter with This move in this process; This synchrotransmitter issues a signal to Programmable Logic Controller after treatment; Arrive this motor speed of coiling electric machine control again after on the one hand passing to the coiling frequency converter, and sensible rotary encoder detection and data are fed back to Programmable Logic Controller handle, carry out the PID computing according to the coiling rotating speed of motor on the other hand; Calculate the working speed of drying room motor; And issue instructions to the drying room frequency converter, and pass to the drying room motor and control this motor, thereby the linear velocity of the swift that drying cylinder that the drying room motor driven and coiling motor driven is reached unanimity; Make the coiling reach permanent tension force automatically, ensured yarn around winding quality.
