Eccentric wheel reverse twisting device

一种偏心轮反搓装置

Abstract

本实用新型公开了一种偏心轮反搓装置,它包括偏心摆动臂、偏心轮、挖钞轮轴、超越离合器、反搓轮轴、反搓轮和从超越离合器;所述的偏心摆动臂一端接触偏心轮,另一端连接超越离合器的外圈;所述的挖钞轮轴为偏心轮的转轴;所述的反搓轮轴的一端连着超越离合器的内圈,另一端连着从超越离合器的内圈;所述的反搓轮连于反搓轮轴上。本实用新型的反搓量可以通过改变偏心轮的偏心量和偏心摆动臂的长度来实现,方便二次开发,更新换代方便,并且驱动力来自挖钞轮的动力轴即挖钞轮轴,其反搓动作与挖钞动作同步,保证有纸张或纸币挖出时就有反搓挡钞动作,提高了工作的准确性可靠性,降低了重张率。
The utility model discloses an eccentric wheel reverse twisting device, which comprises an eccentric swing arm, an eccentric wheel, a currency digging wheel shaft, an overrunning clutch, a reverse twisting wheel shaft, a reverse twisting wheel and a secondary overrunning clutch. One end of the eccentric swing arm contacts with the eccentric wheel while the other end is connected with an outer ringof the overrunning clutch, the currency digging wheel shaft is a rotating shaft of the eccentric wheel, one end of the reverse twisting wheel shaft is connected with an inner ring of the overrunningclutch while the other end is connected with an inner ring of the secondary overrunning clutch, and the reverse twisting wheel is connected onto the reverse twisting wheel shaft. The reverse twistingmagnitude of the eccentric wheel reverse twisting device can be realized by changing the eccentric magnitude of the eccentric wheel and the length of the eccentric swing arm, thereby bringing convenience for secondary development, renewing and upgrading. Besides, driving force is derived from power shaft of a currency digging wheel, namely the currency digging wheel shaft, and the reversing twisting action of the currency digging wheel shaft is synchronous to currency digging action, thereby guaranteeing to have reverse twisting currency stopping action when digging out papers or paper currencies, increasing accuracy and reliability of operation, and reducing chain currency note rate.
