As a brand-new information storage, transmission and identification technology, two-dimensional code (two-dimensional bar code) is widely used in industrial production. In recent years, my country has gradually established The anti-counterfeiting and traceability information systems in the production and distribution fields, such as seeds, pesticides, medicine, medical equipment, and food industries, have implemented QR code traceability.

The variable two-dimensional code cij printer refers to a coding equipment that can print variable two-dimensional code data in real time, usually a UV inkjet printer. UV inkjet printer is a new type of inkjet equipment developed in recent years. Because of its ink characteristics, it is favored by manufacturers in various application industries. UV inkjet printer ink can be dried and cured immediately after being irradiated by ultraviolet curing lamp, with good stability. It can realize coding marking on various materials.

Working principle

UV inkjet printer is a high-resolution inkjet printer with a printing accuracy of>200DPI, which is determined by the number One hundred or more piezoelectric crystals respectively control multiple nozzle holes on the nozzle plate. Through the processing of the CPU, a series of electrical signals are output to each piezoelectric crystal through the drive plate. The piezoelectric crystal deforms and the liquid is stored in the structure. The volume of the device will suddenly change, and the ink will be ejected from the nozzle and fall on the surface of the moving object to form a dot matrix, thereby forming characters, numbers or graphics.

After the nozzle discharges ink, the piezoelectric crystal returns to its original shape, and new ink enters the nozzle due to the surface tension of the ink. Because of the high density of ink dots per square centimeter, UV cij printers can print high-quality text, complex logos, barcodes, and QR codes.

UV ink generally consists of 30-40% of the main resin, 20-30% of the active monomer, and It is composed of a small amount of photoinitiator and auxiliary agents like leveling agent and defoamer. The curing principle is a complex photoreactive curing process: UV ink generates free radicals or cationic monomers after the photoinitiator absorbs the corresponding violet light. The process of polymerization, cross-linking, and instantaneous change from liquid to solid.

UV ink can be quickly dried after being irradiated with a certain range of ultraviolet light at a certain frequency, so that the ink has fast-drying properties, good adhesion, and does not block the nozzle. Easy to maintain and other features.

Application fields

The variable QR code UV inkjet printer can print various variable data in real time, including Bar code, QR code, date and time, shift group number, calculator, graph, table, database, etc. It is widely used in food, medicine, daily chemical, label printing, card printing, packaging and printing, medical treatment, electronics, hardware and other industries. It can be used in flat materials such as aluminum plate, ceramic tile, glass, wood, metal sheet, acrylic plate, plastic, leather, etc. And the logo printing on packaging bags, cartons and other products.
