Is there any encyclopedia knowledge about inkjet printer? I want to see it

according to different working principles, there are two main types of inkjet printer products:
first, continuous ink jet printer, referred to as CIJ type for short, is usually called small character inkjet printer: its principle is: ink is continuously ejected from a single nozzle through pressure, and breaks after crystal oscillation to form ink spots; After being charged by the ink dot and deflected by high voltage, the words are scanned on the surface of the moving object. The ink that is not deflected into words needs to be continuously recycled and recycled in vacuum. In the ink supply mode, there are gear pump ink supply type and pneumatic ink supply type
2. On demand jet printer
(drop on demand) is referred to as DOD type, which is usually called large character printer: its principle is that the nozzle is composed of multiple high-speed precision valves. When spraying words, the valve corresponding to the font opens and closes quickly, [1] the ink is ejected by internal pressure to form characters or graphics on the surface of moving objects. The theory of inkjet printer was invented in the late 1960s, and the world’s first commercial inkjet printer was not produced until the late 1970s. At that time, only a few countries such as the United States, France, Britain and Japan could produce this inkjet printer. Inkjet printer entered China in the early 1990s and has gone through nearly 20 years. Today’s inkjet printer has changed from a high-end equipment with a price of 200000-300000 yuan to an ordinary equipment with a price of 30000-80000 yuan. It can be used in any solid-state product production and processing enterprise. It is widely used in food, beverage, daily chemicals, medicine, electronics, building materials and other fields. Inkjet coding is a small link in the whole production process, but it plays a great role in improving the production efficiency of enterprises, saving labor costs, saving product circulation time, tracking product quality and so on. In China, the early inkjet products were mainly used in aluminum cans of coke, Coca Cola, Pepsi Cola and some high-end beer products. The production speed of such products is very fast and the production volume is very large, which requires that the production line must also use high-speed logo products. Various factors determine the increasing demand of enterprises to use this inkjet method, Thus, it has accumulated initial customer resources for inkjet printer suppliers in the Chinese market
[edit this paragraph] overview of inkjet printer
inkjet printer is a kind of equipment controlled by software and identified on products in a non-contact way. From the inkjet printer consumables used to classify: one is ink inkjet printer; One is non ink inkjet printer (laser inkjet printer); From the working form: one is on-line inkjet printer, which is mainly used for flow production line; A kind of mobile inkjet printer is a kind of mobile inkjet printer, which is similar to the hand-held inkjet printer in the market. At present, there are imported machines, domestic machines and joint venture machines in the Chinese market. In recent years, domestic inkjet printer has grown strongly, and some performance is as good as or better than that of imported inkjet printer. Inkjet printer is accepted by the majority of warehouse users for its wide range of application and strong applicability. In the figure below, the mobile inkjet printer (handheld inkjet printer) is on the left and the online inkjet printer is on the right. Handheld inkjet printer
[edit this paragraph] principle and classification of inkjet printer
I. continuous ink jet printer
(continue ink jet printer) is referred to as CIJ printer for short. Ink jet printer is a non-contact inkjet marking system controlled by software. By controlling the internal gear pump or supplying compressed gas from the outside of the machine, it applies a certain pressure to the ink in the system to make the ink shoot out through a nozzle with an aperture of tens of microns. The crystal oscillation signal added above the nozzle splits the emitted continuous ink line into ink droplets with the same frequency, equal size and certain spacing. Then, the ink droplets are charged respectively when passing through the charging electrode, and the charged amount is controlled by the central processing unit CPU; Then through the detection electrode to detect whether the actual charged amount and phase of the ink drop are correct; Finally, the charged ink droplets deflect in the deflection electric field formed by the deflection electrode, shoot out from the nozzle and hit different positions on the product surface to form various characters, patterns and other marks required. The ink drops that are not charged are sent into the recovery tank and re-enter the ink circulation system inside the machine. Because the ink jet is continuous, the continuous inkjet coder can use many types of ink, especially those that dry very fast (within 1 second). Therefore, continuous inkjet coding technology is very ideal for the printing of products with impermeable surface (such as cans and plastics) that need to be processed quickly after printing. In addition, pigment inks with brighter colors can be used. Due to the relatively high jet speed of continuous jet printing, the jet printing distance of continuous jet printing is usually much farther than that of pulse jet printing (generally more than 10mm), but the jet printing quality will not decline, so there is a large choice for the placement of nozzle position. Most industrial inkjet systems use CIJ technology. The speed of industrial CIJ jet printing system can reach 1000 feet per minute, which is much faster than DOD, but the image quality is also lower than that of DoD technology. CIJ is the best solution for a large number of direct mail orders, food, beverage, medicine and beauty packaging, printing product numbers and marks. It is also used to mark and encode lottery tickets
2. On demand inkjet printer
(drop on demand) is abbreviated as DOD. The nozzle of the industrial on-demand ink supply system is composed of multiple high-precision valves. When spraying words, the valve corresponding to the font opens and closes quickly. The ink is ejected by relying on the internal constant pressure to form characters or graphics on the moving surface. A digital signal produces a drop of ink on the paper, not a stream of ink. The latest DOD nozzle is formed by a more accurate set of dots on the paper, which is similar to the traditional offset printing. Therefore, in the four-color high-precision printing where quality is the most important factor, DOD is the most ideal choice. It can produce an effect close to the photographic quality. The printing speed of DoD is between 100 and 300 feet per minute. DOD uses include wide format printing, color icons for packaging, shopping point display boards, fabrics and large format signs. However, in the industrial packaging industry, due to the limitation of printing speed, it can not be applied to the high-speed packaging assembly line. Many companies are developing high-speed DOD printing equipment that can be used for packaging purposes. There are nearly a dozen brands in Europe alone
III. on demand inkjet technology
(drop on demand) is referred to as DOD type for short. The working principle of DoD inkjet machine is divided into three types: piezoelectric inkjet technology, pressure valve inkjet technology and thermal foaming inkjet technology. 1. Piezoelectric inkjet technology: piezoelectric inkjet machine is also called high-resolution image inkjet machine or high-resolution image inkjet machine. There are 128 or more piezoelectric ceramic crystals on the integrated nozzle to control the spray holes on the nozzle respectively, which are processed by the CPU, and then output a series of electrical signals to each piezoelectric crystal through the driving plate. The piezoelectric crystal is de
formed. In this way, the ink is sprayed out of the nozzle and falls on the surface of the moving object to form a dot matrix, so as to form words, numbers or graphics. Then, the piezoelectric crystal is restored and the new ink enters the nozzle. Because of the high printing quality and the high printing density of the logo per square centimeter. 2. Pressure valve inkjet technology, also known as large character inkjet machine; The nozzle is composed of 7 or 16 groups of high-precision intelligent micro valves. The characters or graphics to be sprayed during printing are processed by the computer motherboard, and a series of electrical signals are output to the intelligent micro solenoid valve through the output board. The valve is started quickly, the ink is ejected into ink dots by relying on the internal constant pressure, and the ink dots form characters or graphics on the surface of the moving printed object
IV. working principle of TIJ
thermal inkjet technology (TIJ for short). Thermal inkjet technology uses a thin-film resistor to heat less than 0.5% of the ink in the ink ejection area to form a bubble. This bubble expands at a very fast speed (less than 10 microseconds) to force ink droplets to eject from the nozzle. The bubble continues to grow for a few microseconds and then disappears back to the resistor. When the bubble disappears, the ink in the nozzle will retract, and then the surface tension will produce suction, pulling new ink to supplement the ink ejection area. Thermal foaming spray printing technology is constructed by such an integrated circular technology program
[edit this paragraph] history of inkjet printer
the concept of CIJ inkjet printer was first patented by British physicist Lord Kelvin in 1867. It was invented by German Siemens company as industrial equipment for commercial application for the first time in 1951. Before the 1990s, only a few countries such as the United States, France, Britain and Japan could produce this inkjet printer. Since the domestic inkjet printer was first invented by the Research Institute under the Ministry of space science and technology in the late 1990s, the monopoly of foreign products has ended. After more than ten years of development and hard catching up with domestic colleagues, the domestic inkjet printer has reached or approached the world level in some aspects of performance and stability. At present, many products have been exported to Europe, America and other developed countries. In 1969, the world’s first commercial inkjet printer was born, and Videojet company of the United States created the history of inkjet printer. After that, many companies around the world launched small character inkjet printer, large character inkjet printer and other products. In the late 1980s, dominoes of the United Kingdom, vidjet of the United States and IMAS of France entered the Chinese market through their Hong Kong agents, Entering the Chinese mainland in 1992, China established the production base in Xiamen, China. In 1994, the first inkjet printer was born in China, and the development of the domestic brand inkjet printer was completed. The world ended with the history of monopoly industry in several developed countries, such as the United States, Germany, Britain and Japan. Let China become one of the countries with the R & D and production capacity of inkjet printer in one fell swoop. Willett company of the UK established a factory in Zhuhai. In 1995, the headquarters of China domino Inkjet Technology Co., Ltd. was established in Beijing. In 1996, the domestic brand Beijing konova Electronic Technology Co., Ltd. was established. In 1999, Lingxin Dajia (Guangzhou) Packaging equipment Co., Ltd. officially became a subsidiary of British Lingxin company. In 1999, the domestic brand Nanjing chengcan Technology Co., Ltd. was established, In 2003, chengcan Technology Co., Ltd. established China’s second inkjet printer R & D center. In 2002, Marken established an office in Shanghai, China. KGK established a factory in Shanghai. Domino Asia Pacific headquarters settled in Shanghai Jinqiao Export Processing Zone. In 2003, vidige acquired Willett and officially entered China in June of the same year, Huiquan International Co., Ltd. and its subsidiary agencies in China become the sole legal general agent of Hitachi brand inkjet printer in mainland Chinese mainland, Hongkong and Macao. In 2004, the New Asia Pacific logistics platform, Shanghai’s (Shanghai) Standard Technology Co., Ltd. was opened in the New Asia Pacific logistics platform. It marks that the development of IMAS in China and the Asia Pacific region has entered a new stage. In 2005, vidige acquired Lingxin Linx. In 2006, Matthews international and Beijing konova Electronic Technology Co., Ltd. jointly established konova Matthews Electronic Technology (Beijing) Co., Ltd. in 2007, Dover group in New York announced the merger of its Ma Two engineering systems companies, Markem Imaje (Markem Imaje) Co., Ltd. and Jizhou Electronics (Shanghai) Co., Ltd., were officially renamed as Jizhou inkjet technology (Shanghai) Co., Ltd. in 2008, domino Inkjet Technology Co., Ltd. was officially renamed as Duomi
