AI Technical Summary
Existing label printer printhead pressure adjustment mechanisms have limited adaptability, making it difficult to achieve precise pressure control for special material media.
By incorporating side plates, pressure beams, a moving mechanism, and a fine-tuning mechanism, the pressure adjustment range is increased, and precise adjustment of the printhead is achieved through the cooperation of a lead screw and a sliding block.
It enables precise adjustment of printhead pressure, meets the requirements of fine control, and adapts to the printing needs of different media materials.
