Inkjet Coding Machine
Professional Packaging Equipment Supplier
1. Product Overview
The inkjet coding machine is automated marking equipment designed to print production dates, batch numbers, barcodes, QR codes, and graphic identifiers on products or packaging. It consists of an ink supply system, printhead, conveyor synchronization system, and control system, suitable for online identification operations in the food, beverage, pharmaceutical, electronics, and building materials industries. Widely applicable to: production date printing, shelf life marking, batch traceability codes, barcode/QR code identification, anti-counterfeiting codes, serial number printing, and other scenarios. Equipment features: high printing speed (up to 300m/min), high printing accuracy, multi-line printing support, non-contact marking without product damage, strong ink adhesion, compliance with food-grade safety standards.
2. Working Principle
Continuous Inkjet (CIJ): Ink forms charged droplets under high-frequency piezoelectric crystal oscillation. Charged droplets deflect in the electric field along preset trajectories to form characters on the substrate, while uncharged droplets are recycled. Thermal Inkjet (TIJ): Heating resistors instantaneously heat ink to create bubbles that expel ink droplets from nozzles onto the substrate. Drop-on-Demand (DOD): Electromagnetic valves control ink path opening/closing, releasing droplets on demand. Laser Coding: High-energy laser beams ablate or discolor substrate surfaces to create permanent marks without consumables. The control system synchronizes printing pace with production line speed for consistent spacing.
