Abstract

The invention relates to the technical field of 3D printing equipment, in particular to a 3D printer automatic leveling hot end quick release module which comprises a back plate, a nozzle assembly, a heating assembly, a rebound assembly and a strain gauge. The springback assembly comprises a guide column and an elastic piece, the heating assembly is in sliding fit with the guide column, and the elastic piece applies vertical elastic force to the heating assembly; the nozzle assembly is detachably connected with the heating assembly, the strain gauge is arranged on the back plate, and the nozzle assembly is provided with a connecting end vertically abutting against the working end of the strain gauge. Through contact between the strain gauge sensing module and the printing platform, leveling of the printing platform is achieved through the 3D printer. After leveling is completed, the springback assembly drives the heating assembly, the nozzle assembly and the strain gauge to reset to the original state, and mistaken touch or mistaken reading caused by residual force is avoided. The nozzle assembly, the heating assembly and the springback assembly are relatively independent, so that the nozzle assembly and the heating assembly can be independently detached, rapid maintenance is conveniently achieved, and the reliability of equipment is improved.
