In the working process of a knitting machine, two magnet exciting coils at two ends of the same guide rod are intermittently powered on or powered off, namely, one of the two magnet exciting coils is powered on or powered off, the power on or powered off frequency corresponds to that of a high-speed needle, the palm sheet frame slides left and right and swings for a certain angle around the guide rod, and in the swinging process around the guide rod, the entering end of the yarn is pulled, so that one end of the yarn entering the yarn guide sheet is in a loose state, the pulling force of the warp yarn for the warp yarn is relatively small, and the possibility of the warp yarn for the warp yarn is effectively reduced.

Through the motion frequency of excitation coil control palm piece frame, have the controllability height, occupation space is little, advantages such as speed governing scope is big, exists the headspace between the vertical adjacent palm piece frame, and the swing of palm piece frame can not make both mutual interference, under the different knitting demands, can wear to establish different warp on each palm piece frame, and its motion frequency also can set up respectively alone.

In the palm sheet yarn guide device capable of preventing yarn breakage, the swing amplitude of the palm sheet frame is 8-20 degrees.

The swinging amplitude is about 10 degrees in general, the swinging amplitude is realized through the threads of the guide rods and the transverse movement distance, the palm sheet frames are used as the reference, the palm sheet frames swing forwards and backwards by 5 degrees, the avoidance space required between the palm sheet frames is not too large, of course, the width of the palm sheet frames and the parameters of a knitting machine are matched with the swinging amplitude, and the higher effect is achieved through debugging.

The distance between the relative iron plate of armature around being equipped with excitation coil is adjustable, and the regulation mode is: the armature is fixed to a bolt which is screwed to the support.

In the palm sheet yarn guide device capable of preventing yarn breakage, a gap is formed between every two adjacent yarn guide sheets, and the length of each sliding rod is more than twice of the sum of the thicknesses of all the yarn guide sheets on the sliding rod.

The yarn guide pieces are not high in density easily, and can move mutually to avoid the influence on the yarns due to large friction force between the yarns and the threading holes.
