Further, the upper gland of described diplopore bearing block 4 is provided with keyway, is fixedly connected with spline axle 10 by the second key 12, the outer ring of bearing 8 is provided with stop rib 13, stopping gear 3 and end cap 9 are fastened on stop rib 13 two ends, and stopping gear 3 is fixed, can not left and right play; The inner ring of freewheel clutch 5 is fixed on spline axle 10 by the first key 6.
Further, described freewheel clutch 5 outer ring is provided with retainer 7, retainer 7 is made up of locking plate 15, steel ball 16 and spring 17, stopping gear 3 inner ring is provided with the locking groove 14 coordinated with locking plate 15, promote steel ball 16 by spring 17 and then promote locking plate 15 to locking groove 14, reaching stop object.
The present invention compared with prior art its beneficial effect is:
No matter 1. the present invention is after conversion process operated gear or fine spining machine stop, it can grip middle roller transmission automatically, in time, control the reversing of middle roller, and gripping can be removed automatically, in time when fine spining machine is driven to guarantee normal operation, this just can be avoided the quality problems such as thickness joint, yarn driving broken end producing yarn to greatest extent, solves the defect all the time existed of rear roller transmission in fine spining machine;
2. the present invention to be arranged in fine spining machine in rear roller driving-chain, rear roller power transmission shaft (i.e. the power intake of middle rear roller) in direct control, make full use of the mechanical property of freewheel clutch, control procedure without the need to manual operation, also without the need to additionally increasing power;
3. compact conformation of the present invention, smooth running is reliable.
