Accompanying drawing 5 is test crotch and continuous test regulating system shell split figure.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, technical scheme of the present invention is further described in detail.
Embodiment:
Automatic monitoring instrument for yarn tensile force as shown in Figures 1 to 4, have upper cartridge body 14 and lower box body 12, swing arm 5 is equipped with on upper cartridge body top, on swing arm long-armed two dynamometry thread guides 2 are housed, a cylinder thread guide 3 is housed on the galianconism of swing arm, be positioned on the upper cartridge body 14 of swing arm both sides and respectively be provided with a positioning guide wire device 1, the yarn of turnover is played the role of positioning.Swing arm 5 is connected on the upper cartridge body 14 by swing arm rotating shaft 6, the swing arm rotating shaft links to each other with an end of the steel disc coil spring 10 that is arranged on lower box body 12, the other end of steel disc coil spring 10 links to each other with bull gear 8, bull gear 8 is meshed with pinion 9, pinion 9 is connected on the stepper motor 11, screw of stepper motor 11 usefulness is installed on the motor fixed leg 13, helps the convenient centre-to-centre spacing of adjusting big pinion.On the upper cartridge body 14 of swing arm 5 lower ends, test crotch 4 is housed, the test crotch is between two dynamometry thread guides 2.The test crotch is fused by connector 41, coupler body 42 as shown in Figure 5.Connector 41 is a hollow cylinder, the annular circular arc body of coupler body 42 for not being connected, and circular arc body is carried out the transition to the minimum of chimoto by maximum.On coupler body, be provided with slick and sly through hole or recess with the corresponding position, end of hook.The end of hook makes yarn be unlikely to run out of the coupler body outside a little less than the last plane of through hole or recess.Dynamometry crotch 4 be connected with phosphorus bronze sheet 71 (connecting portion of dynamometry crotch 4 41 is by the joint pin 72 on the phosphorus bronze sheet 71), phosphorus bronze sheet is installed in the test regulating system shell 7, be pasted with two foil gauges on the phosphorus bronze sheet, foil gauge is electrically connected with the test regulating system that comprises single-chip microcomputer.
During work, when yarn 15 passes through positioning guide wire device 1, dynamometry thread guide 2, cylinder thread guide 3,4 operations of tension test crotch, the power that test crotch 4 produces makes metallic elastic body (phosphorus bronze sheet) distortion, the foil gauge of being close on the metallic elastic body induces operating yarn tension, by electronic circuit, the tension parameters that output is corresponding.Compare by the tension value that single chip microcomputer is handled and the user is provided with, when finding that yarn tension is bigger than normal or less than normal, single chip microcomputer sends instruction, drive stepper motor 11 forward or reverse, be connected pinion 9 forward or reverse thereupon on the machine shaft, by being engaged on the bull gear 8 on the pinion 9, (adopting the steel disc coil spring to connect in the centre has been cushioning effect to drive steel disc coil spring 10, the swing arm variation frequency is reduced), the swing arm rotating shaft 6 and the swing arm 5 that are fixed on the steel disc coil spring 10 just swing up and down, the amplitude that swing arm 5 is upwards put is big, then yarn is at positioning guide wire device 1, dynamometry thread guide 2, cylinder thread guide 3, the path of walking between the tension test crotch 4 is longer, approach curvature is bigger, S-shaped advancing, frictional force increases, and then yarn tension has just increased (seeing shown in Figure 1).Otherwise, swing arm 5 is to the bottom, then just short, the approach curvature in the path walked between positioning guide wire device 1, dynamometry thread guide 2, cylinder thread guide 3, tension test crotch 4 of yarn is with regard to little (seeing shown in Figure 2), even 5 thread guides needn't each all contact, pass in that interstitial hole is unsettled, frictional force between yarn and the thread guide is just little, and yarn tension has just reduced.
Automatic monitoring instrument for yarn tensile force of the present invention is applicable to up-coiler, bobbin winder, and warping machines, covering filament machine and other need be controlled the equipment and the machinery of yarn tension.
Mode and the host computer of each automatic monitoring instrument for yarn tensile force of the present invention with serial communication can be connected together, realization is to processing, the demonstration of setting, control and the data of each automatic monitoring instrument for yarn tensile force, thereby uses and control one group of automatic monitoring instrument for yarn tensile force synchronously.
