研究开发了一种炮弹标志自动印刷系统，能够对76～155 mm各种口径的定装式、分装式后装炮弹标志进行自动印刷。通过对炮弹外形及其标志印刷条件的分析，确定了系统的总体设计方案和基本组成，研究并解决了系统设计过程中送弹机构、卡弹机构、网印机构、同步机构等关键的技术问题，并设计了气动系统及PLC控制系统。实际使用情况表明，系统工作状态良好，运行可靠。

A new model of automatic ammunition mark printing system was developed. It can print mark on shell with diameter 76～155 mm. Based on analysis of shell shape and printing condition requirements, the overall structure of the system was developed, and several key technical problems such as feeding shell, holding shell, printing mechanism, and synchronizer were studied and solved. The pneumatic and PLC control system were designed. The practical operation showed that the system is working well and of high reliability.
