The invention discloses an automatic spraying
machine, and relates to the technical field of three-dimensional object spraying, in particular to a closed digital automatic spraying
machine controlledby a computer. The automatic spraying
machine comprises a rack, a supply air outlet, a main exhaust port, an
exhaust pipe, a cooling and heat removal port, an
electric control box,
metal box sealing panels, a
coating pressure
barrel and a
coating recovery barrel. An automatic
nozzle of a four-axis device is moved around a workpiece for
spray coating, and located at the upper portion of a machine body; a workpiece is fixed through a workpiece shaft device and a
tailstock integration device, and the workpiece shaft device is located in the middle of the machine body; a gas filtering water tank is located below the machine body; and
metal box sealing panels and glass
doors which can be opened and closed are installed on the periphery of the gas filtering water tank. The automatic spraying machine is in the
closed state in work. Gas for
spray coating of the workpiece is filtered through the gas filtering water tank, and then discharged in a centralized mode, and
air pollution is reduced, so that the effect of guaranteeing the
physical health of staff is achieved; and the national
environmental protection policy and development direction are met, and the automatic spraying machine facilitates transportation and promotion, and has wide prospects.
