Paper cocooning frame,an excellent cocooning device that can significantly improve the quality of cocoon and silk,has been widely used in sericulture production. An electric lifting device for paper cocooning frame is developed to solve the time-consuming and laborious problem in lifting the paper cocooning frame when labor-saving silkworm rearing( ground rearing) is employed for sericulture production. The device is mainly comprised of a transmission mechanism,a lifting mechanism and a power device. The transmission mechanism is mainly composed of a pulley and a steel wire rope.The lifting mechanism is mainly composed of a bottom plate,a bearing with seat,a ratchet stop mechanism,a spring,a bobbin,a transmission shaft and a coupling. The power device is mainly composed of a motor,a motor support,a movable bracket and a power supply. The device is driven by a motor to rotate the lifting mechanism,and the lifting and lowering of the paper cocooning frame is completed through the action of the transmission mechanism. The device has been tested in small-scale labor-saving sericulture production,showing excellent performance. It is stable and reliable,which can obviously promote the labor efficiency of farmers in sericulture production.
