Wire breaking protection mechanism for radiation type fly shuttle on plastic flat wire circular knitting machine

Abstract

The invention discloses a wire breaking protection mechanism for a radiation type fly shuttle on a plastic flat wire circular knitting machine. The mechanism includes a fly shuttle main frame, the topof the fly shuttle main frame is fixedly provided with a fixation plate, a ratchet-type wire breaking locking assembly is installed in the fixation plate, and the ratchet-type wire breaking locking assembly is composed of a fixation screw, an upper burner gauze cone, a ratchet wheel, a ratchet wheel pressure plate, a probe arm, a probe-arm wire through hole, a wire breaking locking base, an upperburner gauze cone shaft, an upper burner gauze cone spring, a probe-arm clamp knife and an adjustment screw. The ratchet wheel type mechanism is separated from a bake mechanism and integrated into the burner gauze cone, interference with weft yarn is quite small before the wire breaking standard is reached, and the mechanism can be locked instantaneously at the time of wire breaking. The inverseclamping effect of the ratchet wheel and the probe arm is used for achieve instantaneous locking of a thread spool, the mechanism can completely avoid unnecessary waste of labor and materials causedby weft breaking of all plastic circular looms, and the productivity and the yield are greatly improved.

Description

technical field [0001] The invention relates to the technical field of plastic flat yarn circular knitting machines, and more particularly to a wire breakage protection mechanism for a radial shuttle on the plastic flat yarn circular knitting machine. Background technique [0002] The existing technology on the market is mainly synchronous with the brake mechanism on the shuttle, the looser the cable, the greater the braking force. When the thread is completely broken, the brake braking force is the largest, but at the same time, the braking force of the brake mechanism is indirectly transferred to the weft thread by means of a lever, in this way, after the thread is broken, the bobbin itself will be eliminated due to the inertia of the weft thread. In case of a shuttle hit, control the braking mechanism to extend a "probing arm" (or steel wire) to press the weft thread, and then obtain the real-time tension of the weft thread, and then control the weight of the brake to ach...

Problems solved by technology

However, when running at high speed, the spool itself also rotates at high speed due to the thread going out, so if the thread breaks at this time, due to the inertia of the high-speed rotation of the spool, Guan Xi will continue to go out of the thread, which will cause a very serious situation of out-of-control knotting "knocking the shuttle", and it will cost a lot of time.
