[0002] As a new information storage, transmission and identification technology, QR code (two-dimensional barcode) is widely used in industrial production. In recent years, my country has gradually established product anti-counterfeiting and traceability information systems in the fields of production and circulation. For example, seeds, pesticides, medicines, medical devices, food industries, etc. have implemented QR code traceability. Variable QR code inkjet printer refers to a coding device that can print variable QR code data in real time, usually UV inkjet printer. UV inkjet printer is a new type of inkjet equipment developed in recent years. Due to its ink characteristics, it is favored by manufacturers in various application industries. The ink printed by UV inkjet printer can be dried and cured immediately after being irradiated by ultraviolet curing lamps. It has good stability and can realize coding and marking on various materials.

[0003] At present, when UV inkjet printers spray QR codes, they need to spray the QR codes onto the product surface through a spray terminal. In order to facilitate the QR code spraying, the spray terminal is generally designed on the outside of the UV inkjet printer. In the rainy season, the air will be relatively humid, causing water vapor to enter the inside of the spray terminal, which will cause the lens to be blurred and have a certain impact on the QR code spraying. At the same time, when the UV inkjet printer is not working, dust can easily enter the inside through the spray terminal, which will also cause the lens to be blurred and affect the normal operation of the UV inkjet printer. Therefore, a QR code spraying system is proposed. Utility Model Content

At this time, the linear module 3 will drive the cleaning cotton 8 and the inkjet terminal 2 to move upward. At this time, the cleaning cotton 8 will move to the inside of the inkjet terminal 2. At this time, the base 7 will fit against the bottom outer wall of the inkjet terminal 2. At this time, the inside of the inkjet terminal 2 will be cleaned or protected when not in use.
