The invention discloses a multi-needle staggered direct-writing electrostatic spinning device and a method for making grating lines. The device includes an XY-axis moving platform, a lifting device, an electrostatic spinning high-voltage power supply, a plurality of electrostatic spinning direct-writing needle assemblies, The collecting plate, multiple driving devices, and the infusion needles of the adjacent electrospinning direct-writing needle assemblies are misplaced, and the distance between them is more than 150mm in the Y direction. The device and method for making grating lines in this patent use piezoelectric ceramic actuators to control and adjust the spacing and stepping distance of multiple electrospinning direct writing needle components, thereby controlling the spacing of grating lines and greatly improving the manufacturing process. The accuracy of the grating line; and keep the multiple electrospinning direct-writing needle components at an appropriate distance, avoiding the discharge phenomenon between adjacent infusion needles, making the field strength distribution of the electrostatic field of the system more uniform, reducing the deposition offset, Improve silk quality.
