Air pressure type atomizing and ink-spraying marking device

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.

Description

technical field [0001] The invention relates to a pneumatic atomization inkjet marking device, which is used for marking products on an automatic production line. Background technique [0002] In many automatic production lines, after the product processing is completed, the product performance needs to be tested to ensure the yield of the final product. After the inspection, the product needs to be marked to distinguish whether the product is qualified. The common method is to put a mark on the surface of the unqualified product. At present, it is common to use inkjet marking to mark products. However, the ink droplets ejected by the general inkjet method are relatively large, and the ink droplets are not uniform enough, and it is not easy to dry, and a drying process is often required. Although spray guns are often used to mark products in engineering, especially for some more sophisticated products or equipment, which can accurately mark products, but for many markings ...

AI Technical Summary

Problems solved by technology

However, the ink droplets ejected by the general inkjet method are relatively large, and the ink droplets are not uniform enough, and it is not easy to dry, and a drying process is often required

Although spray guns are often used to mark products in engineering, especially for some more sophisticated products or equipment, which can accurately mark products, but for many markings with relatively large inkjet range and low requirements for inkjet fineness Marking with a javelin is too costly

In addition, in order to achieve a better spraying effect, the spraying equipment on the market is generally relatively large in size and lacks sufficient flexibility.
