Technical Field
The invention relates to the technical field of plastic flat wire circular knitting machines, in particular to a broken wire protection mechanism of a radiation type flying shuttle on a plastic flat wire circular knitting machine.
Background
The existing technology in the market is mainly synchronously matched with a brake mechanism on a shuttle, and the brake braking force is larger as the thread is looser. When the thread is completely broken, the braking force of the braking mechanism is maximum, and meanwhile, the braking force of the braking mechanism is indirectly transferred to the weft thread in a lever type, so that the situation that the thread axle shaft itself runs out to tie a knot and hit a shuttle due to the fact that the inertia rotation weft thread is out of control after the thread is broken is eliminated, the braking mechanism is controlled to extend a probe arm (or a steel wire) to press the weft thread, and then the situation that the tension of the weft thread is real and the weight of the brake is controlled to achieve the protection means for limiting the inertia rotation.
The same function of the "" feeler arm "" is available in the market to press the weft and simultaneously increase the tension of the original weft, which may reduce the rotating speed to reduce the weft tension and the broken thread, but also reduce the productivity, and the capability of not achieving instantaneous locking by only braking during high-speed operation only possibly eliminates the inertia to stop, the reliability is low and the mechanism is more complex compared with the "" ratchet type "", and the mechanism is not easy to be damaged by the inertia
The speed and tension of weft yarn outgoing in running weaving have direct interest relationship, and the rotating speed must be increased to improve the yield so as to challenge the tension and maximum tension of the weft yarn. However, when the circular knitting machine runs at a high speed, the bobbin rotates at a high speed due to the outgoing line, so if the line is broken, the continuous outgoing line due to the inertia of the high-speed rotation of the bobbin can cause a serious uncontrolled knotting phenomenon of shuttle collision, great manpower is consumed to thread again and even damage the flying shuttle or equipment, production stagnation is caused due to halt, and in order to realize the highest-speed reaction locking and minimize the interference on the weft in the normal running of the unbroken line, the broken line protection mechanism of the radiation type flying shuttle on the circular knitting machine for the plastic flat wire is provided.
