Embodiment Construction
[0012] The computerized flat knitting machine of the present invention adopts a keep solenoid (Keep solenoid), which uses a permanent magnet, and its working principle is similar to that of all rectilinearly moving electromagnets. When the coil is excited, the electromagnet slider moves to the iron core and finally stops at the end position, and when the power is cut off, the electromagnet slider remains at the original position. If the electromagnet slider is to return, it must be applied reverse voltage (or current).
[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] As shown in the figure, the present invention includes an electromagnet 1, an electromagnet slide bar 2, a connecting piece 3, a shuttle piece 4 and a voltage conversion circuit. The electromagnet slide bar 2 is connected with the electromagnet 1, and the shuttle selection part 4 is connected with the electromagnet ...

The invention discloses a computerized flat knitter dropping detection device based on groove type photoelectric switch, which comprises an electromagnet, an electromagnet sliding bar, a connecting piece, a shuttle selecting piece and a voltage conversion circuit, wherein the electromagnet sliding bar is connected with the electromagnet; the shuttle selecting piece is connected with the electromagnet sliding bar through the connecting piece; the lower part of the electromagnet is provided with the groove type photoelectric switch; the voltage conversion circuit is connected with the groove type photoelectric switch; and the bottom of the electromagnet sliding bar penetrates through the electromagnet and shields the groove type photoelectric switch at the state that the electromagnet sliding bar is energized and moves downwards. According to the device, whether a computerized flat knitter shuttle selecting device (dropping) works normally or not can be detected in real time, and alarm signal is sent out because of irregular working.
Description
technical field [0001] The invention relates to a computerized flat knitting machine shuttle selection device (blindness) detection device for normal operation, specifically a computerized flat knitting machine based on a slot-type photoelectric switch. Background technique [0002] The shuttle selection device of the computerized flat knitting machine is operated by an electromagnet. But the part that this electromagnet moves, because the working space position is relatively narrow, and the use environment is bad, easily causes the shuttle selection device not to move or over-moves because of the problem of mechanism transmission or the problem of electromagnet itself. Contents of the invention [0003] The object of the present invention is to design a computerized flat knitting machine blind detection device based on a slot-type photoelectric switch. [0004] What the present invention needs to solve is the problem that the shuttle selection device does not act or over...
