Title:
DOUBLE-Z-AXIS DRIVING STRUCTURE AND SINGLE-NOZZLE 3D PRINTER HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/062249
Kind Code:
A1
Abstract:
Disclosed in the present utility model are a double-Z-axis driving structure and a single-nozzle 3D printer having same. The double-Z-axis driving structure comprises a platform, a bracket provided on the platform, and a cross beam slidably provided on the bracket and located above the platform; a first motor and a second motor arranged at intervals are provided on one side of the lower end of the bracket; the upper end of the first motor is provided with a first lead screw which is transmittingly connected to the first motor and is vertically provided; the upper end of the second motor is provided with a first lead screw which is transmittingly connected to the second motor and is vertically provided; the two ends of the cross beam are respectively fixed on the first lead screw and the second lead screw by means of lead screw nuts; the upper ends of the first lead screw and the second lead screw are respectively provided with a first synchronizing wheel and a second synchronizing wheel; the first synchronizing wheel and the second synchronizing wheel are connected by a synchronous belt. In the present utility model, by means of a double-motor double-lead screw driving mode, the balance and stability of the cross beam in the moving process are improved; moreover, the synchronous belt is added between the two lead screws to ensure the synchronization of the two lead screws, thereby causing the cross beam and the platform to be always kept parallel.
