[0002] Inkjet printing technology, as a non-contact, pressure-free, plate-free printing method, has been widely used in daily printing, industrial printing and other fields. One of its core components is the inkjet head, and the driving mechanism of the inkjet head is the key to determining the quality and performance of inkjet.

[0003] The driving mechanism of the inkjet head directly determines the inkjet quality of the inkjet head, including the accuracy, speed, stability, etc. of the inkjet. Optimizing the design of the driving mechanism can reduce the manufacturing cost of the inkjet head and improve the cost performance of the equipment. An efficient driving mechanism can reduce the energy consumption of the equipment, which is in line with the development trend of green environmental protection.
