Ink supply system for tire numeric printer

Abstract

An ink supply system for a tire numeric printer comprises a left ink supplier ink sleeve, a left ink exhaust bin, a left ink supplier, a left ink supply pipe, a printing pressure bin, a printing spraying nozzle, a right ink supply pipe, a printing character cart sliding frame, a right ink supplier, a right ink exhaust bin, a left ink cleaning scraping plate, a right ink cleaning scraping plate, a left ink sucker, a right ink sucker, a left waste ink sucking pipe, a right waste ink sucking pipe, a left ink cleaner, a right ink cleaner and a right ink supplier ink sleeve. As the ink supply system commonly composed of a left ink supply structure and a right ink supply structure is used for supplying ink to the printing pressure bin, the printing pressure bin and the printing spraying nozzle jointly act on numeric printing of a tire, the stability of the scientific designing process largely reduces the plugging rate and relieves the problems of ink backflow, ink leakage, deformation of a chip contact pin, damage to a chip, existence of impurities, volatilization and the like, continuous stability of the tire numeric printer is guaranteed, and a user can use the tire numeric printer more conveniently and at ease.

Description

Technical field: [0001] The invention belongs to the field of tire digital printers, in particular to an ink supply system for tire digital printers. Background technique: [0002] The ink supply system of traditional tire digital printers mostly applies the siphon principle, that is, in two containers filled with liquid and connected by a siphon tube, the liquid always flows from the container with high pressure to the container with low pressure. We know that during the printing process, the ink cartridge of the printer will continuously deliver ink to the nozzle. While delivering the ink, the pressure inside the ink cartridge is also dropping, and it needs to inhale the same volume of air to maintain the pressure balance. The ink supply system will start from The air replenished in the vent hole of the ink cartridge is replaced by ink. The ink cartridge is also replenished with the same capacity of ink while delivering ink to the nozzle. The ink replenished into the inner...

Problems solved by technology

[0009] However, the ink supply systems used in all the inkjet printers mentioned above have the following designs: split ink cartridge ink supply system and integrated ink cartridge ink supply system. The system’s ink sacs and hoses have a short service life and are easy to block the nozzles. The integrated ink cartridge ink supply system has a high cost. The thermal foaming nozzles used in it have a short service life, but the hoses often do not enter ink. The above two designs There are the following disadvantages: 1. The ink indicator on the printer is always red, and it will not work when the printer is turned off and on again; 2. The decoder is invalid after decoding the chip of the ink cartridge; 3. The printer does not perform cleaning after pressing the cleaning button; when canceling printing When working, the ink indicator light on the printer is on; when the computer is restarted, the ink indicator light on the printer is on; 4. Repeat the cleaning and testing process

Small ink dots appear on the paper when printing; 5. Large ink spots often appear on the paper when printing; 7. No matter what paper is used for printing, there is always some ink left on the edge of the paper; 8. There is always ink on the paper feed roller of the printer. Some test lines printed with ink stains are always disconnected; 9, and there is a phenomenon of color crossing; 10, the ink cartridge leaks
