Description of goods: First, the basic principle Computer-controlled printing needle in X, Y two dimensional plane by a certain trajectory, while the role of print in compressed air under the needle to do high-frequency impact of movement and The workpiece beautiful prints user mark. 2, Introduction DQ series marking printer using standard printer parallel interface to communicate with the computer can control all connected fixtures (such as pneumatic tooling, solenoid Tooling, tooling and other circumference side), flat or nearly flat on the implementation of a variety of print work mark. Add rotating tooling can also be used to print the circumference surface.Third, characteristics and main functions1, print fonts should be clear, neat, printed words the same depth, the font is not deformed. 2, the words in English characters, numerals, any random by computer graphics can be input, scheduling. 3, can automatically number (serial number) printed. 4, print content can be automatically called and saved and automatically save the file to retain. 5, the network can automatically control the printing. 6, can automatically print bar codes. 7, print depth adjustable. Fourth, technical parameters 1, the print depth: word deep 0.1 - 2mm (adjustable). 2, the print height: character size set by the user, the smallest not less than 1mm. 3, Print Speed: 1-3 characters per second print (2 words shall prevail). 4, the print format: plane or arc 140 × 80 (according to the workpiece required). 5, print the header height: ≤350. 6, frame size: 340 × 440. 7, the printer for the linear guide rail, a self-sealing can be self-lubricating function. 8, are printed material hardness: ≤ HRC50. 9, power supply: AC 220V ± 15%, total power 300W. 10, the working pressure: 0.3- 0.8Mpa. 11, ambient temperature:-10C ° - +45 C °.
