Title:
AUTOMATIC RELOADING DEVICE FOR 3D PRINTER, AND AUTOMATIC RELOADING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/253791
Kind Code:
A1
Abstract:
An automatic reloading device for a 3D printer, and an automatic reloading method. Said device comprises an extrusion mechanism and a switching mechanism (6); the extrusion mechanism comprises a driving wheel (7), a first driven wheel set (41), a second driven wheel set (51), a first rotating clamp (4), a second rotating clamp (5), and a tension spring (43); one end of each of the first rotating clamp (4) and the second rotating clamp (5) is hinged to a cover body (1), and the other end of each of the first rotating clamp (4) and the second rotating clamp (5) is connected to the tension spring (43); the switching mechanism (6) comprises a switching rod (61) rotatably connected to an extrusion base (12), and a switching handle (62) fixedly connected to the switching rod (61); the end of the first rotating clamp (4) close to the tension spring (43) is fixedly connected to a first limiting column (42), and the end of the second rotating clamp (5) close to the tension spring (43) is fixedly connected to a second limiting column (52); and when the switching handle (62) is in an initial state, two ends of the switching rod (61) respectively abut against the first limiting column (42) and the second limiting column (52), such that the first driven wheel set (41) and the second driven wheel set (52) are both separated from the driving wheel (7). The present device has a high automation degree, increases the working efficiency, and reduces labor costs.
