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.Existing Yarn tension detection apparatus structure is as follows: bar magnet and magnet are fixed on the plastics adjusting rod, and adjusting rod is installed on the fixed head by two parallel metallic springs, and the Hall displacement inductor is installed on the fixed head; 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 generation displacement signal and passes to micro treatment control system, thereby the control motor speed guarantees the tension force output that yarn is constant, namely reaches the control of yarn tension.It is too much that existing Yarn tension detection apparatus affects the factor of tension value accuracy in detection of yarn, for example the aging distortion of plastics adjusting rod moves it not in place easily, two parallel metallic springs are long-time to be occurred uneven situation after using will to affect adjusting rod to the distance between the fixed head is distance between magnet and the Hall displacement inductor, the Hall displacement inductor is long-time to use rear sensitivity to descend, the Hall displacement inductor is installed the loosening of insecure appearance, and magnet is long-time, and the shift value that all the Hall displacement inductor is detected such as deform after using is inaccurate.In sum, there is the low problem of yarn tension value detection accuracy in the Yarn tension detection apparatus on the existing knitting machine.
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 a kind of knitting machine, comprise holder, wiring board, bar magnet, bar magnet Connection Block, metallic spring, foil gauge and damping oil, holder comprises front holder and the rear holder that is arranged parallel to each other, wiring board is installed on the rear holder, on the front holder mounting groove is set, splendid attire damping oil in the mounting groove, foil gauge is close on the metallic spring, the metallic spring bottom is installed in the mounting groove that fills damping oil, all speckles with damping oil on metallic spring and the foil gauge; Between front holder and the rear holder wired pipe is set, places wire in the wired pipe, wiring board is connected wire with foil gauge and connects; One end of metallic spring is connected on the bar magnet Connection Block, and bar magnet is installed on the bar magnet Connection Block; Foil gauge is out of shape and changes the resistance signal of self with the distortion of metallic spring; Described foil gauge is resistance strain gage or capacitive strain sheet.
As preferably, foil gauge is bonded at the middle part of metallic spring, and result of use is best.
Adopted the Yarn tension detection apparatus on a kind of knitting machine of technique scheme, yarn passes through bar magnet during use, bar magnet makes the metallic spring distortion by the bar magnet Connection Block under the effect of pressure, thereby the foil gauge that is close on the metallic spring is also deformed so that its resistance signal changes, and this resistance signal amplified processing by wiring board, control the tension force output that motor speed guarantees that yarn is constant with this.Adopt the tension value of the structure detection yarn of metallic spring and foil gauge, detects sensitiveer and stable, long service life, post processing circuitry is simple, effectively reduces cost, the raising reliability.Damping oil can improve the anti-fatigue performance of metallic spring, the course of action that makes the distortion of metallic spring and foil gauge steadily is that the resistance signal of foil gauge can steadily be exported, the infringement of avoiding spiking that circuit and motor are caused, damping oil plays the buffering and shock preventing effect simultaneously, keeps metallic spring distortion and reseting procedure steadily to carry out.Damping oil on the foil gauge can play good vibration reduction and cushioning, water-tight performance, and electrical apparatus insulation is good, good with plastic cement elastomeric material compatibility, thereby avoids the foil gauge induction too sensitive, and unsettled phenomenon occurs.The advantage of the Yarn tension detection apparatus on this knitting machine is that novel structure is simple, has greatly reduced the factor that affects the tension value of yarn accuracy in detection, and the degree of accuracy that the yarn tension value detects is high.
Description of drawings
Fig. 1: the structural representation of the embodiment of the invention.
The specific embodiment
1 couple of the present invention is described further below in conjunction with accompanying drawing.
Yarn tension detection apparatus on a kind of knitting machine as shown in Figure 1 mainly is made of holder 1, wiring board 3, bar magnet 5, bar magnet Connection Block 4, metallic spring 8, foil gauge 7 and damping oil.
Above-mentioned metallic spring 8 is steel spring leafs, and foil gauge 7 can be resistance strain gage or capacitive strain sheet, and adopts the result of use of resistance strain gage best.Damping oil can improve the anti-fatigue performance of metallic spring 8, the course of action that makes metallic spring 8 and foil gauge 7 distortion steadily is that the resistance signal of foil gauge 7 can steadily be exported, the infringement of avoiding spiking that circuit and motor are caused, damping oil plays the buffering and shock preventing effect simultaneously, keeps metallic spring 8 distortion and reseting procedure steadily to carry out.Especially the damping oil on the foil gauge can play good vibration reduction and cushioning, water-tight performance, and electrical apparatus insulation is good, good with plastic cement elastomeric material compatibility, thereby avoids foil gauge 7 inductions too sensitive, and unsettled phenomenon occurs.
