Drive device and spraying metering device

Abstract

The utility model discloses a kind of driving device and spraying metering device, driving device includes cylinder body, and is internally provided with first containing cavity;Driving assembly, including driver and moving piece;Driving assembly is set to one end of cylinder body, moving piece is built-in first containing cavity, driver is driven connection with moving piece, and moving piece can be driven to move along the axial direction of first containing cavity;One end of connecting shaft is detachably connected with moving piece.The power output end of the driver of the scheme is driven to connect with moving structure, and moving structure can be driven to repeatedly move along the axial direction of first containing cavity, when moving structure moves in first containing cavity, since connecting shaft is connected with moving piece, therefore can synchronously drive connecting shaft to follow movement, at this time, the push block connected with connecting shaft can be pushed to follow movement.The layout of overall structure is more compact, which is conducive to reducing the volume of the entire coating liquid metering device, so that it can adapt to various space limited application scenarios.
