Abstract
The invention provides an air pressure type atomizing and ink-spraying marking device which is used for marking a product on an automatic production line. In the air pressure type atomizing and ill-spraying marking device, air generated by an air compressor is divided into two paths after passing through an air tank and a main reducing valve, one path of air flows to a liquid transporting unit for transporting marking liquid in a pressure tank to an atomizing nozzle, and the other path of air passes through an air transporting unit to reach the atomizing nozzle so as to realize the atomization of the marking liquid. In addition, an electrical control unit is used for controlling the on or off of pipelines through which the two transporting units lead to the nozzle. The device can be expanded to be of a multi-branch ink-spraying marking manner, and each branch can be independently controlled. The invention has the characteristics of simple structure, low cost, convenience and flexibility; and marked signs are clear and easy to dry after the marking liquid is atomized, therefore, the air pressure type atomizing and ink-spraying marking device can be applied to the marking on the automatic detection production line in multiple fields.
