【摘要】：在當(dāng)今工業(yè)快速發(fā)展情況下,各種商品為了標(biāo)識(shí),需要打印各種標(biāo)碼,因而出現(xiàn)了各種各樣不同使用環(huán)境與操作特點(diǎn)的噴碼與打標(biāo)機(jī)。根據(jù)應(yīng)用環(huán)境與使用成本要求,噴字機(jī)的設(shè)計(jì)要求也不同。本文根據(jù)在400度左右溫度條件下的使用要求,主要從噴嘴、供墨、控制、防高溫工程設(shè)計(jì)等方面進(jìn)行設(shè)計(jì)。突破了傳統(tǒng)噴碼機(jī)對(duì)墨水質(zhì)量要求高的限制。本機(jī)對(duì)墨水質(zhì)量的要求很底,能使用各種價(jià)格便宜質(zhì)量差的墨水,而不用擔(dān)心墨水堵塞的問(wèn)題。 主要討論按需噴墨式噴印方式噴碼機(jī)原理,在此基礎(chǔ)上提出了一些可行的系統(tǒng)設(shè)計(jì)方案,并進(jìn)行了實(shí)驗(yàn),主要內(nèi)容如下： 一、噴字系統(tǒng)的核心部件噴嘴的設(shè)計(jì)。噴字最終的實(shí)現(xiàn)單元是噴嘴,系統(tǒng)里所有工作都是圍繞噴嘴進(jìn)行運(yùn)行的,所以噴嘴的設(shè)計(jì)是重中之重。本文主要以多種防堵措施結(jié)合的方式進(jìn)行研究與設(shè)計(jì),最終是以實(shí)現(xiàn)防止噴嘴堵塞,降低噴嘴對(duì)墨水質(zhì)量依耐為目標(biāo)的設(shè)計(jì)要求； 二、結(jié)合噴嘴結(jié)構(gòu)與工作效率要求,對(duì)電磁閥與驅(qū)動(dòng)電路進(jìn)行選取與設(shè)計(jì),使其可以滿(mǎn)足高速工作需要； 三、根據(jù)噴嘴結(jié)構(gòu)、壓力需求及防堵塞要求,對(duì)供墨液壓回路結(jié)構(gòu)進(jìn)行了研究分析與設(shè)計(jì)。使之可以實(shí)現(xiàn)墨水顏料不斷循環(huán)流動(dòng)并提供穩(wěn)定的噴寫(xiě)壓力。 四、控制系統(tǒng)采用51單片機(jī)做控制器,采用串行通信方式與上位機(jī)微機(jī)聯(lián)接。51成本低,控制能滿(mǎn)足需要,上位機(jī)微機(jī)各種資源豐富,處理能力強(qiáng),兩者結(jié)合各取所長(zhǎng)； 五、進(jìn)行控制程序的算法研究,編寫(xiě)能有效實(shí)現(xiàn)控制噴寫(xiě)要求的,控制與窗口程序； 六、對(duì)噴寫(xiě)執(zhí)行機(jī)構(gòu)進(jìn)行設(shè)計(jì),拓展了噴寫(xiě)功能與使用范圍。 總的來(lái)說(shuō)由于系統(tǒng)采用多重防堵設(shè)計(jì),降低了對(duì)墨水顏料的要求,大大節(jié)約耗材成本,可以在高溫、多灰塵的惡劣環(huán)境下使用,提高了系統(tǒng)的穩(wěn)定性與可靠性。
[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.
