QQ 194535455 Design of transmission mechanism of semi automatic machine to nuclear jujube Abstract? Drupe fruit to pit fruit processing process in a very important pretreatment process. In recent years, with the continuous improvement of people's material life level, manual processing is ing more and more expensive, people on food to nuclear quality requirements are increasingly stringent. Therefore, development performance excellent to kernel machines and other equipment is necessary. Jujube go nuclear machine is posed of a feeding, positioning, go nuclear, conveying device and a transmission mechanism and a machine body, a hopper. By artificial management, control and consistency of the coordinated action of each unit. Feeding device will jujube automatic queuing fed into the conveying device, by conveying device will jujube vertically one by one into the rotation of the upper part of the upright positioning mechanism to nuclear punching needle mechanism under the linear movement will remove the positioning of each pressed the jujube jujube, jujube jujube nucleus is removed from Fuzheng positioning mechanism falls into. The main contents of this paper: (1)according to the requirements of process action order and coordination to the intended motion cycle chart; (2)the punching mechanism and an intermittent motion mechanism of selection; (3)selection and evaluation of mechanical movement scheme; (4) mechanical transmission system and the implementing agencies were size motion calculation.
