1、 Classification of Pneumatic Marking Machines

Pneumatic marking machines are generally divided into two categories:

1. Desktop pneumatic marking machine:

Suitable for marking tags, nameplates, and small workpieces (with a height of less than 500mm, easy to move to the workbench for marking workpieces), etc.

2. Portable pneumatic marking machine:

Suitable for workpieces that are not easy to move to the workbench for marking, the mobile marking machine head is used to mark the workpiece. It inherits the original advantages of desktop pneumatic marking machines and has made significant improvements in product applicability, making up for the shortcomings of desktop marking machines. It is widely used in automotive beams. The marking of motorcycle frames, large pipelines, irregular workpieces, nameplates, and various difficult to move workpieces is lightweight, easy to operate, and portable, and can be used in conjunction with laptops or microcontrollers.

2、 Application of desktop pneumatic marking machine

1. Printing of numbering, names, trademarks, and production dates for engine, piston, body, frame, chassis, connecting rod, engine, cylinder, and other components of automobiles, motorcycles, etc;

2. Printing of rack numbers for electric vehicles, bicycles, motorcycles, etc; 3. Printing of labels for various goods, vehicles, and equipment products;

4. Various mechanical components, machine tools, hardware products, metal pipes, gears, pump bodies, valves, fasteners, steel, instruments and meters. Marking of metal such as mechanical and electrical equipment; Made of plastic.

3、 The principle of desktop pneumatic marking machine

By inputting the content of Chinese and English characters and graphics to be printed into a computer, the computer marking software converts the content into digital control signals, which are transmitted to the controller to drive printing and print characters and graphics composed of continuous dot matrix on the workpiece;

The needle moves along a set trajectory in the X-Y two-dimensional plane, while the printing needle prints a concave mark composed of a dense dot matrix on the surface of the workpiece under the action of compressed air.
