Go up and down to return trigger

The utility model provides a go up and down to return trigger, include: the lift seat is along the motion of vertical direction, return flat platform, have the loading end that bears the work piece, around the first axle rotatable install in the seat goes up and down, drive arrangement, set up in go up and down the seat with return between the flat platform drive it winds to return flat platform the first axle rotates in order to adjust the angle of loading end with respect to the horizontal plane. So design realizes through the rotation upset of returning flat platform that the work piece slips into and the roll -off under the action of gravity, only the drive return flat platform and rotate, the work piece realizes through self gravity that the structure is simple and easy in the motionof returning flat bench, the reliability is high, equipment overall cost is lower in addition. 本实用新型提供了种升降返板机，包括：升降座，沿竖直方向运动；返板平台，具有承载工件的承载面，绕第轴线可转动安装于所述升降座；驱动装置，设置于所述升降座和所述返板平台之间，驱动所述返板平台绕所述第轴线转动以调节所述承载面相对于水平面的角度。如此设计，通过返板平台
