High-precision conveying mechanism and synchronous conveying device thereof

The invention discloses a synchronous conveying device. The synchronous conveying device comprises a rack, a motor, a sensor, a screw rod assembly and a gear assembly, wherein the motor is fixed below the rack, the motor controls movement of the screw rod assembly through the gear assembly, the gear assembly is located at the front end of the screw rod assembly and provided with a positioning strip, and the sensor is located beside the positioning strip. According to the synchronous conveying device, the positioning strip is monitored by the sensor, the rotation speed and direction of a screw rod can be precisely controlled under the action of the motor and the gear assembly, and accordingly the running speed of a packaging box is controlled through the screw rod assembly so that the purpose of high-precision quantitative packaging can be achieved. 本发明公开了种同步输送装置，包括机架、电机、传感器、螺杆组件和齿轮组件，所述电机固定于所述机架的下方，所述电机通过所述齿轮组件控制所述螺杆组件的运动，所述齿轮组件位于所述螺杆组件的前端，且所述齿轮组件上设有定位条，所述传感器位于所述定位条的侧边。本发明通过传感器对定位条的监测，在电机和齿轮组件的作用下，可以精确控制螺杆的转速
