Kind Code:
A1
Abstract:
A stable and reliable nozzle assembly of a 3D printing device, comprising: a storage cylinder (1), a ferrule (2), a first connection seat (4), a C-shaped limiting plate (15), a valve (10) and a nozzle (11); the valve (10) is disposed at a bottom portion of the storage cylinder (1), and the first connection seat (4) is disposed at a side of the ferrule (2); an outer circle of the storage cylinder (1) is provided thereon with a support ring (12) located below the ferrule (2), the support ring (12) being provided thereon with a pressure ring (7); a circle of first balls (9) is arranged in a circular array on the support ring (12), a circle of second balls (6) is arranged in a circular array on the pressure ring (7), and a circle of third balls (8) is embeddedly disposed on outer circles of the support ring (12) and the pressure ring (7), an inner wall of the C-shaped limiting plate (15) contacting the first balls (9), the second balls (6), and the third balls (8), respectively. By means of the described manner, the stable and reliable nozzle assembly of a 3D printing device employs a first mechanical arm and a second mechanical arm to drive the storage cylinder (1) and the C-shaped limiting plate (15), respectively; the movement accuracy is high, and the problems of instability and slow speed caused by large inertia are prevented.
