Abstract

The invention discloses a 3D printing pen nozzle replacing device which comprises a fixed plate, wherein a device cavity is arranged in the middle of the fixed plate; a fixed block is fixedly connected with the inner wall of the device cavity; a first threaded rod is arranged on the fixed block in a penetrating manner; the fixed block is connected with the first threaded rod in a threaded manner;a gear is fixedly connected with one end, away from the inner wall of the device cavity, of the first threaded rod; a sliding groove is formed in the inner wall opposite to the device cavity; a rack is arranged in the sliding groove; the rack and the gear are meshed with each other; a buffer device is fixedly connected with the inner wall of the sliding groove; a propping block is fixedly connected with one end, away from the inner wall of the sliding groove, of the buffer device; the propping block props against the side wall of the rack; a rotating shaft is fixedly connected with one end, away from the first threaded rod, of the gear; the rotating shaft penetrates the inner wall of the device cavity and extends to the outside of the device cavity. The device is reasonable in structure design, easy to operate, and capable of rapidly replacing nozzles of a 3D printer, so that the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a nozzle replacement device for a 3D printing pen. Background technique [0002] Based on 3D printing technology, the 3D printing pen uses hot-melt PLA, ABS and other plastic filaments to print and form the 3D products needed, especially suitable as an educational tool to inspire children. [0003] Since the 3D printing pen utilizes thermal melting to form 3D products, the plastic filament is in a molten state when extruded, and the thickness and shape of the extruded thermal fuse are determined by the thickness and shape of the nozzle opening of the nozzle of the 3D printing pen. The nozzles of the existing 3D printing pens are all fixed. Since they cannot be replaced, the thickness and shape of the extruded fuses are single, which limits the diversity of shapes of formed 3D products. Therefore, it is necessary to provide a replaceable nozzle and a nozzle replacement device...
