First, the structure of the printer and printing principle 1. The structure of the printer: from the printer head, mechanical transmission and heating oven three parts. (1) printing head: the special line wheel, the word box clip wheel, interchangeable word boxes, ink wheels, ink cartridges and their brackets, fine-tuning screws, and attached to the wire measurement and control of the count and stop printing control line door. (2) mechanical transmission system: divided into mechanical pull-line and take-up line two parts. Mechanical pull-line from the pulley pulley, spline shaft, spline clutch, wire pull mechanism, electromagnet and other components; take-up part of the motor, worm gear, the main spline
