振动给料机是一种常用的给料设备，振动给料机本身不具备控制给料精度的功能。设计一种插板阀来控制振动给料机给料的速度，从而在物料不同称量阶段，来控制物料的称量精度，达到精确称量物料的效果。%Vibrating feeder is a commonly used feeding equipment for materials,but it is not provided with the function of accuracy control.Design a flat gate valve to control the feeding speed of the vibrating feed-er,so the weighing accuracy of materials can be controlled in different weighing periods,and achieve the re-sult of materials weighed accurately.
