The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the embodiment of the present invention for computer flat-knitting machine head electromagnetic-type electronic slide cam selector;
Fig. 2 is the drive circuit works schematic diagram of the embodiment of the present invention for computer flat-knitting machine head electromagnetic-type electronic slide cam selector;
In accompanying drawing, the mark of each parts is as follows: 1, needle-selecting blade, 2, the slide cam selector shell, 3, rotational pin, 4, back-moving spring, 5, coil, 6, iron core.
the specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Fig. 1 is the structural representation of the embodiment of the present invention for computer flat-knitting machine head electromagnetic-type electronic slide cam selector; This electromagnetic-type electronic slide cam selector comprises needle-selecting blade 1, slide cam selector shell 2, rotational pin 3, back-moving spring 4, coil 5, iron core 6 and drive circuit, described rotational pin 3 is arranged on the centre of needle-selecting blade 1, described needle-selecting blade 1 untie-sell 3 left-right rotation that can rotate, described back-moving spring 4 one ends are needle-selecting blade 1 immediately, described coil 5 and iron core 6 are positioned at needle-selecting blade 1 below, and coil 5 around with iron core 6 on.
The slide cam selector of the electromagnetic-type electronic for computer flat-knitting machine head that the present invention mentions has adopted clapper-type electromagnetic
Iron is realized the needle selection action, and the coil 5 in this electromagnetic-type electronic slide cam selector passes to electric current by drive circuit, while in coil 5, having electric current to pass through, produce magnetic flux in the magnetic circuit of iron core 6 and working gas gap composition, set up magnetic field, produce electromagnetic force, adhesive needle-selecting blade 1.The sense of current in this coil 5 is determined by drive circuit, when drive circuit during to coil 5 forward voltage supply, be connected with forward current in coil 5, and when the forward current value reaches certain certain value, the left-hand electromagnetism the suction-combining force that electromagnet produces, be enough to overcome the resistance of 4 pairs of needle-selecting blades 1 of back-moving spring, needle-selecting blade 1 untie-sell 3 that can rotate turns to left position; During to coil 5 reverse voltage supply, in coil 5, be connected with reversing the current when drive circuit, the electromagnetic force that original electromagnet produces changes, and under the effect of dextrad electromagnetism the suction-combining force and back-moving spring, needle-selecting blade 1 resets at right position.Like this, by changing the energising direction of solenoid, just can change the position of needle-selecting blade 1 left and right, realize that digitalized needle selecting machine is stable, quick, needle selection action reliably.
