【摘要】：在当今工业快速发展情况下,各种商品为了标识,需要打印各种标码,因而出现了各种各样不同使用环境与操作特点的喷码与打标机。根据应用环境与使用成本要求,喷字机的设计要求也不同。本文根据在400度左右温度条件下的使用要求,主要从喷嘴、供墨、控制、防高温工程设计等方面进行设计。突破了传统喷码机对墨水质量要求高的限制。本机对墨水质量的要求很底,能使用各种价格便宜质量差的墨水,而不用担心墨水堵塞的问题。主要讨论按需喷墨式喷印方式喷码机原理,在此基础上提出了一些可行的系统设计方案,并进行了实验,主要内容如下：一、喷字系统的核心部件喷嘴的设计。喷字最终的实现单元是喷嘴,系统里所有工作都是围绕喷嘴进行运行的,所以喷嘴的设计是重中之重。本文主要以多种防堵措施结合的方式进行研究与设计,最终是以实现防止喷嘴堵塞,降低喷嘴对墨水质量依耐为目标的设计要求；二、结合喷嘴结构与工作效率要求,对电磁阀与驱动电路进行选取与设计,使其可以满足高速工作需要；三、根据喷嘴结构、压力需求及防堵塞要求,对供墨液压回路结构进行了研究分析与设计。使之可以实现墨水颜料不断循环流动并提供稳定的喷写压力。四、控制系统采用51单片机做控制器,采用串行通信方式与上位机微机联接。51成本低,控制能满足需要,上位机微机各种资源丰富,处理能力强,两者结合各取所长；五、进行控制程序的算法研究,编写能有效实现控制喷写要求的,控制与窗口程序；六、对喷写执行机构进行设计,拓展了喷写功能与使用范围。总的来说由于系统采用多重防堵设计,降低了对墨水颜料的要求,大大节约耗材成本,可以在高温、多灰尘的恶劣环境下使用,提高了系统的稳定性与可靠性。
[Abstract]:With the rapid development of industry, in order to mark a variety of commodities, it is necessary to print a variety of marking codes, so there are a variety of spray codes and marking machines with different use environment and operating characteristics. According to the application environment and the application cost requirements, the design requirements of the printer are also different. According to the application requirement of temperature around 400 degrees, this paper mainly designs from nozzle, ink supply, control, anti-high temperature engineering design and so on. It breaks through the limitation of the high ink quality of the traditional inkjet printer. This machine is very basic to the quality of ink, can use a variety of cheap and poor quality ink, without worrying about the problem of ink clogging. This paper mainly discusses the principle of on-demand inkjet printer, and puts forward some feasible system design schemes. The main contents are as follows: first, the design of nozzle, the core part of the system, is presented. The final unit of spray is the nozzle, all the work in the system is run around the nozzle, so the design of the nozzle is the most important. In this paper, a variety of anti-blocking measures are mainly used to research and design, finally, to prevent nozzle clogging and reduce the ink quality dependence of the nozzle as the goal of the design requirements; Secondly, according to the requirements of nozzle structure and working efficiency, the solenoid valve and driving circuit are selected and designed to meet the needs of high-speed operation. Thirdly, according to the nozzle structure, pressure requirements and anti-blocking requirements, the structure of the hydraulic circuit for ink supply is studied and analyzed and designed. Enables continuous circulation of ink and pigments and provides stable spray pressure. Fourth, the control system uses 51 single chip microcomputer as the controller and serial communication mode to connect with the upper computer. 51 low cost, the control can meet the needs, the host computer is rich in various resources, strong processing capacity, the combination of the two to take advantages; Fifthly, the algorithm of the control program is studied, and the control and window program which can effectively realize the requirement of controlling the spray writing is compiled; sixth, the design of the spray writing executing mechanism is carried out, which expands the function and the scope of use of the spray writing. In general, the system adopts multiple anti-blocking design, reduces the requirements for ink pigments, greatly saves the cost of consumables, can be used in the harsh environment of high temperature and dust, and improves the stability and reliability of the system.
