The yarn tension detection device for the knitting machine has the advantages of novel structure and high accuracy in yarn tension detection.
Description
Technical field
The present invention relates to the accessory field of knitting machine, the Yarn tension detection apparatus that uses on especially a kind of knitting machine elastomeric yarn Yarn-feeding mechanism.
Background technology
During automatic knitting machine work, tension force how to control yarn is one of essential condition that affects the knit product quality.Elasticity Yarn-feeding mechanism on the knitting machine mainly is comprised of Yarn tension detection apparatus, micro treatment control system, electric motor drive system and motor, detect the Tensity size of yarn during work by Yarn tension detection apparatus, then tension value is passed to micro treatment control system, through providing a motor drive signal to motor driven systems after the micro treatment control system analyzing and processing, thereby by the driving work of this signal control motor, reach the accurate control of yarn tension.Yarn tension detection apparatus role in whole process is maximum, and whether the tension value of the yarn that it detects accurately will directly affect the quality of knit product.All there is the low problem of yarn tension value detection accuracy in Yarn tension detection apparatus in the market.
Summary of the invention
The objective of the invention is the deficiency that exists for the Yarn tension detection apparatus that overcomes on the above-mentioned existing knitting machine, a kind of novel structure is provided, the Yarn tension detection apparatus on the high knitting machine of yarn tension value detection accuracy.
In order to realize the foregoing invention purpose, the present invention has adopted following technical scheme:
Yarn tension detection apparatus on the knitting machine, comprise fixed head, wiring board, eccentric adjusting wheel, Hall displacement inductor, adjusting rod, magnet, bar magnet, holder and two parallel metallic springs, article two, parallel metallic spring rear end is fixed on the fixed head, front end is fixed on the adjusting rod, and two parallel metallic springs are all vertical with adjusting rod; The right-hand member of adjusting rod is provided with connecting axle, holder is in the right side of adjusting rod, is provided with the connecting axle die cavity in the holder, is provided with damping oil in the connecting axle die cavity, the connecting axle of the right-hand member of adjusting rod inserts and is provided with in the connecting axle die cavity of damping oil, and connecting axle is left and right sides traveling priority in the connecting axle die cavity; Bar magnet and magnet are fixed on the adjusting rod, bar magnet drive adjusting rod and on the magnet move left and right; The Hall displacement inductor is fixed on the front portion of wiring board, and the Hall displacement inductor on the wiring board is corresponding with the magnet positions coupling on the adjusting rod, and the Hall displacement inductor is between two parallel metallic springs; Wiring board is movably arranged on the fixed head by the eccentric adjusting wheel, the straight-line groove that connects before and after fixed head is provided with, and wiring board is in the straight-line groove, eccentric adjusting wheel control circuit board front and back traveling priority in the straight-line groove of fixed head.
Adopted the Yarn tension detection apparatus on the knitting machine of technique scheme, yarn passes through bar magnet during use, make under the effect of pressure bar magnet drive adjusting rod and on magnet move, be subjected to displacement between magnet and the Hall displacement inductor, the Hall displacement inductor catches displacement and produces displacement signal, displacement signal via line plate amplifies to be processed, and controls the tension force output that motor speed guarantees that yarn is constant with this.The metallic spring parallel with vertical two of adjusting rod make that magnet moves steadily and in order, damping oil can play the effect of buffering and damping, to guarantee the stationarity of adjusting rod displacement and reseting procedure, has guaranteed the accuracy of yarn tension value detection; The front and back linear position of eccentric adjusting wheel control circuit board on fixed head, be used for regulating the air line distance between Hall displacement inductor and the magnet, to satisfy the yarn of different displacement signal sensitivity, also can be used for adjusting the induction sensitivity of Yarn tension detection apparatus.In sum, the advantage of the Yarn tension detection apparatus on this knitting machine is novel structure, and the accuracy that the yarn tension value detects is high.
