Technical Field
The invention belongs to the technical field of spindle parts of textile machinery, and particularly relates to a pneumatic spindle.
Background
The spindle is one of main components of twisting winding on a two-for-one twister, and the working principle of threading the yarn by the existing pneumatic spindle is as follows: the spindle rod is arranged to be a central through hole, the central through hole is communicated with a yarn passing tube arranged on the lining spindle assembly, the bottom of the central through hole is connected with an origin, yarn is led into the yarn from the upper end of the yarn passing tube and penetrates into the upper end of the central through hole of the spindle rod, a yarn passing channel is arranged on the side part of a twisting disc fixed on the spindle rod, air flows out of the yarn passing channel of the twisting disc to form negative pressure for adsorbing the yarn, the yarn is conveyed outwards through air flow adsorption traction, and the yarn is twisted through the twisting disc. The existing spindle blade center through hole is vertically arranged, air flow can only draw yarns by means of sub-negative pressure suction through the center through hole, but yarns penetrating through the top of the yarn passing tube need to pass through a longer-distance lining spindle assembly, the holding power of the yarns is smaller by means of air flow negative pressure traction, if yarn heads are placed in the lining spindle and far away from a yarn passing channel of a spindle twisting disc, the yarns are difficult to draw by means of air flow, and therefore twisting efficiency of the yarns is reduced.
