When Fig. 2 is the logical forward electricity of electromagnetic valve, be in the structure cut-away view that the top stop bit is put;
When Fig. 3 is the logical oppositely electricity of electromagnetic valve, be in the structure cut-away view that top stop bit is down put;
Among the figure: valve body 1, electromagnet 2, fixed support 3, first rigid bearing 4, first back-moving spring 5, first fast pulley 6, permanent magnet 7, first limited block 8, second rigid bearing 9, second back-moving spring 10, second fast pulley 11, second limited block 12, first electrode 13, second electrode 14.
The specific embodiment
The present invention can control two kinds of Trace speed electromagnetic valves of tufted carpet machine yarn, and it mainly comprises valve body 1, electromagnet 2, fixed support 3, first rigid bearing 4, first back-moving spring 5, first fast pulley 6, permanent magnet 7, first limited block 8, second rigid bearing 9, second back-moving spring 10, second fast pulley 11, second limited block 12, first electrode 13 and second electrode 14.The electromagnet 2 and the fixed support 3 of valve body 1, forward and reverse energising are injection molded into one, electromagnetism falls 2 first electrode 13 and second electrode 14 and draws from valve body 1, permanent magnet 7 is fixed on the valve body center by first rigid bearing 4 and second rigid bearing 9, first back-moving spring 5 and second back-moving spring 10, first limited block 8 and second limited block 12, and valve body 1 slides up and down relatively, and first fast pulley 6 and second fast pulley 11 are installed in the two ends of permanent magnet 7.
When electromagnet 2 fed the 24V direct current, according to the forward and reverse variation that feeds the line solenoid valve loop current, (the electromagnet upper end was the N utmost point when leading to forward current, and the lower end is the S utmost point in the magnetic field of the magnetic pole that changes at valve body 1 center; The electromagnet upper end is the S utmost point when leading to reversing the current, the lower end is the N utmost point), (the magnet upper end is the N utmost point and the magnetic direction of permanent magnet makes progress always, the magnet lower end is the S utmost point), according to the principle that the magnetic field same sex is repelled each other, there is a natural attraction between the sexes, make permanent magnet 7 relative valve bodies 1 do upwards, move downward, the control yarn is walked yarn by the speed of walking the yarn wheel of friction speed.
(the anodal switch-on coil electrode 13 of 24V when electromagnet 2 feeds 24V forward dc electricity, negative pole switch-on coil electrode 14), the electromagnetic valve coil center produces stationary magnetic field upwards, and permanent magnet produces magnetic field upwards, according to the magnetic field principle of same-sex repulsion, make permanent magnet 7 relative valve bodies 1 move upward, compress second back-moving spring 10, driving first fixed block 8 moves upward, take turns with the yarn of walking that yarn overwhelms speed one with first fixed block, the 8 first fixing fast pulleys 6, make yarn walk yarn according to the speed of walking the yarn wheel of speed one.
(the anodal switch-on coil electrode 14 of 24V when electromagnet 2 feeds the reverse direct current of 24V, negative pole switch-on coil electrode 13), the electromagnet coil center produces downward stationary magnetic field, and permanent magnet 7 produces magnetic field upwards, according to the magnetic field principle of opposite sex attraction, make permanent magnet 7 relative valve bodies move downward, compress first back-moving spring 5, driving second fixed block 12 moves downward, take turns with the yarn of walking that yarn overwhelms speed two with second fixed block, the 12 second fixing fast pulleys 11, make yarn walk yarn according to the speed of walking the yarn wheel of speed two.
When electromagnet 2 no powers (coil electrode 13 and coil electrode 14 obstructed direct currents), electromagnet coil does not produce magnetic field, and permanent magnet produces magnetic field upwards, according to the magnetic field law, make permanent magnet 7 under the effect of first back-moving spring 5 and second back-moving spring 10, be returned to original rest position, yarn does not contact with the yarn wheel of walking of controlling yarn speed, and does not walk yarn speed thereby do not control yarn.
The present invention can control that two kinds of Trace speed electromagnetic valves of tufted carpet machine yarn volume is little, compact conformation, life-span are long, can control two kinds of different yarn speed of walking, and has reduced production cost; The energy adaptation runs up, energy consumption is low, the control Trace speed moves accurately and reliably, improves the operating efficiency of tufted carpet machine.
