Two bottoms of the metal spring sheets are mounted in the installation groove filling with the damping oil. The circuit board is connected with the strain gages through leads. One end of the metal spring sheets is connected with the magnetic-rod connecting seat. The magnetic rod is disposed on the magnetic-rod connecting seat. The strain gages distort with distortion of the metal spring sheets. The yarn-tension detection apparatus on the knitting machine has the advantages that a structure is novel and simple, factors affecting detection accuracy of a yarn tension value are greatly reduced and the detection accuracy of the yarn tension value is high.
Description
Technical field
The utility model relates to the accessory field of knitting machine, the Yarn tension detection apparatus used 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 affected the knit product quality.Elasticity Yarn-feeding mechanism on 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, provide 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 is the role maximum in whole process, 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 adjuster bar, and adjuster bar is arranged on fixed head by two parallel metallic springs, and the Hall displacement inductor is installed on fixed head; During use, yarn passes through bar magnet, under the effect of pressure, make bar magnet drive adjuster bar and on magnet move, between magnet and Hall displacement inductor, be subjected to displacement, the Hall displacement inductor catches displacement generation displacement signal and passes to micro treatment control system, thereby control the tension force output that motor speed guarantees that yarn is constant, reach 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 adjuster bar easily moves it not in place, occur after two long-time uses of parallel metallic spring that it is the distance between magnet and Hall displacement inductor that uneven situation will affect adjuster bar to the distance between fixed head, the Hall displacement inductor is long-time uses rear sensitivity to descend, the Hall displacement inductor is installed the loosening of insecure appearance, magnet is long-time, and the shift value that all can make the Hall displacement inductor detect 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 existing knitting machine.
The utility model content
Goal of the invention of the present utility model is the deficiency existed in order to overcome Yarn tension detection apparatus on above-mentioned existing knitting machine, and 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 utility model 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, wiring board is arranged on holder, mounting groove is set on holder, splendid attire damping oil in mounting groove, foil gauge is close on metallic spring, and the metallic spring bottom is arranged in the mounting groove that fills damping oil; Wiring board is connected by wire with foil gauge; One end of metallic spring is connected on the bar magnet Connection Block, and bar magnet is arranged on the bar magnet Connection Block; Foil gauge is out of shape with the distortion of metallic spring.
As preferably, described foil gauge is resistance strain gage or capacitive strain sheet.
As preferably, all speckle with damping oil on metallic spring and foil gauge.Damping oil on 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.
Adopted the Yarn tension detection apparatus on a kind of knitting machine of technique scheme, during use, yarn passes through bar magnet, under the effect of pressure, bar magnet makes the metallic spring distortion by the bar magnet Connection Block, thereby making to be close to foil gauge on metallic spring also deforms and makes its resistance signal change, and this resistance signal is amplified to processing by wiring board, control with this tension force output that motor speed guarantees that yarn is constant.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 costs the raising reliability.Damping oil can improve the anti-fatigue performance of metallic spring, the course of action that makes metallic spring and foil gauge distortion is steadily that the resistance signal of foil gauge can steadily be exported, the infringement of avoiding spiking to cause circuit and motor, damping oil plays the buffering and shock preventing effect simultaneously, keeps metallic spring distortion and reseting procedure steadily to carry out.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 accuracy that the yarn tension value detects is high.
The accompanying drawing explanation
Fig. 1: the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described further.
Yarn tension detection apparatus on a kind of knitting machine as shown in Figure 1, mainly consist 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.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 is steadily that the resistance signal of foil gauge 7 can steadily be exported, the infringement of avoiding spiking to cause circuit and motor, 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 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.
During use, yarn 6 is by bar magnet 5, under the effect of pressure, bar magnet 5 makes metallic spring 8 distortion by bar magnet Connection Block 4, thereby making to be close to foil gauge 7 on metallic spring 8 also deforms and makes its resistance signal change, and this resistance signal is amplified to processing by wiring board 3, then pass to micro treatment control system, provide a motor drive signal to motor driven systems after processing by analysis, drive motor work, thereby control the tension force output that motor speed guarantees that yarn is constant, reach the accurate control of yarn tension.
