On the precision production line of modern manufacturing, the coding and marking equipment is like a silent guardian, quietly leaving a unique "password" on the surface of the product. These seemingly inconspicuous logos actually contain huge energy, which is related to the safety, traceability and brand protection of the product, and has become an indispensable key link in modern production.
Invisible code printing: the "invisible shield" to protect product safety
The invisible code printing equipment can be called the "invisible shield" of product safety. It prints codes that cannot be directly seen by the naked eye on the surface of the product, giving the product information a mysterious coat. These invisible codes are invisible under normal conditions, but they can be clearly displayed with the help of specific equipment or light sources. Common invisible code printing methods include ultraviolet printing, infrared printing, and invisible printing using special inks and materials.
In terms of function, the invisible code printing equipment has powerful tracking and anti-counterfeiting capabilities. By using special inks, it can print codes on the surface of the product that can only be recognized by specific equipment. These codes are like the "identity cards" of products, which can be used to track product sources, prevent counterfeiting and traceability management. In industries such as food and medicine that have extremely high safety requirements, invisible code printing equipment plays a vital role. It can effectively prevent counterfeiting and tampering of product information, ensure the authenticity and consistency of product information during production, logistics and sales, provide security for consumers, and enhance the reputation of the brand.
Invisible code printing equipment also has the advantages of high efficiency, automation and versatility. It can seamlessly connect with modern production lines, support high-speed and high-precision printing processes, and significantly improve production efficiency. In addition to printing invisible QR codes and digital codes, it can also print information such as date, batch number, production number, etc., providing strong support for the information management of production lines.
Principle of coding technology: Decoding the secret of "password" generation
The working principle of coding identification equipment is like a precise "dance", in which continuous inkjet technology and on-demand inkjet technology are the two protagonists in this "dance".
Continuous inkjet technology (CIJ) Ink enters the spray gun under pressure. The spray gun is equipped with a crystal oscillator, which vibrates to form fixed-spaced ink dots after the ink is sprayed out. After CPU processing and phase tracking, some ink dots are charged with different charges at the charging electrode, and different offsets occur when passing through a high-voltage magnetic field of several thousand volts. Finally, they fly out of the nozzle and fall on the surface of the moving product to form a dot matrix, thus forming text, numbers or graphics. The remaining uncharged ink dots are directly shot into the recovery tank and recycled for reuse. This technology can achieve high-speed and continuous printing, which is suitable for mass production needs.
Drop-on-demand inkjet technology (DOD) is divided into three types: piezoelectric inkjet technology, valve-type inkjet technology, and thermal foaming inkjet technology. In piezoelectric inkjet technology, multiple piezoelectric crystals on the integrated nozzle control the nozzle holes on the nozzle plate respectively. Through CPU processing and the output of electrical signals on the driver board, the piezoelectric crystal is deformed, causing the ink to be ejected from the nozzle and fall on the surface of the moving object to form a dot matrix. After the piezoelectric crystal returns to its original state, new ink enters the nozzle under the action of surface tension. Due to the high density of ink dots per square centimeter, this technology can print high-quality text, complex logos, barcodes and other information. The nozzle of the pressure valve inkjet printer is composed of multiple groups of high-precision intelligent micro valves. When printing, the computer motherboard processes the characters or graphics to be printed, and outputs electrical signals to the intelligent micro solenoid valve through the output board. The valve opens and closes quickly, and the ink is ejected into ink dots by relying on the internal constant pressure, forming characters or graphics on the surface of the moving printed object. Thermal foaming inkjet technology uses a thin film resistor to heat a small amount of ink in the ink ejection area to form a bubble, which quickly expands and forces the ink droplets to eject from the nozzle. After the bubble disappears, the ink in the nozzle retracts, and the surface tension generates suction, pulling new ink to replenish the ink ejection area.
Laser inkjet printer: "precision engraver" of industrial identification
Laser inkjet printer is like a "precision engraver" in the field of industrial identification. With its unique working principle and excellent performance, it has demonstrated strong strength in many industries.
The working principle of the laser inkjet printer is to use a high-energy laser beam to instantly vaporize part of the material on the surface of the object, thereby forming a permanent mark. It is like an extremely fine "light knife" that "carves" the required information on the surface of the product. Unlike traditional inkjet printing, laser inkjet printing is non-contact, avoiding problems such as nozzle wear and ink clogging caused by contact between the nozzle and the product, ensuring the clarity and accuracy of the inkjet printing effect.
In the food and beverage industry, laser inkjet printers are indispensable equipment on the production line. It can print production date, shelf life, ingredient list and other information on beverage bottles and snack packaging bags at high speed and accuracy, ensuring that the information of each product is clear and accurate, so that consumers can drink it with confidence. Moreover, the permanence of laser inkjet printing effectively prevents information from being tampered with, ensuring food safety and brand reputation. In the pharmaceutical industry, laser inkjet printers play a key role. The traceability code, drug name, specifications and other information on each box of medicine are related to the patient's medication safety. The information printed by the laser inkjet printer is clear and difficult to tamper with. With the drug traceability system, once a problem occurs, it can be quickly and accurately traced back to the production batch, production line and even the source of raw materials of the drug, effectively ensuring the quality and safety of the drug, and making supervision more convenient and efficient. In the cosmetics industry, laser inkjet printers can print delicate and exquisite patterns and texts on cosmetic bottles and packaging boxes, such as brand logos, ingredient descriptions, expiration dates, etc., which not only improves the appearance quality of the product, but also enhances brand recognition. Moreover, the durability of laser inkjet printing ensures that the information remains clear during product sales and use, and will not be blurred or fall off due to environmental factors such as friction and humidity. In the electronics and home appliance industries, laser inkjet printers can print codes on the surface of tiny components with high precision, meeting the electronics industry's demand for refined production.
