Abstract
The invention relates to an automatic printing interval adjusting lettering method and device. When a printing medium enters a printing area, if the thickness of the printing medium is smaller than or equal to an interval between a paper pressing block and a printing drum, at the moment, a printing head is located at the lowest position, deformation of a torsional spring on a carriage unit split body B is minimum, and generated torsion is used for adjusting counter-acting force generated when the printing head works; if the thickness of the printing medium is larger than the interval between the paper pressing block and the printing drum, the paper pressing block makes contact with the printing medium, the printing medium pushes a carriage unit split body C to move upwards along the carriage unit split body B, the carriage unit split body C drives the carriage unit split body B to rotate around a carriage unit guide shaft, at the moment, the deformation of the torsional spring on the carriage unit split body B begins to be increased, and the generated torsion enables the paper pressing block to press the printing medium. The device is novel in design and simple in structure, the printing head does not incline, the service life of the printing head is long, the printing medium thickness application range is large, and the device has high practical value and a wide application prospect.
