Abstract

The present invention relates to a continuously working piston extrusion nozzle device and its use method, wherein, the piston extrusion nozzle device comprises a mounting block on which a left barrel and a right barrel are fixed. barrel, the bottom of the left barrel and the right barrel are provided with a feed port and a discharge port, and the discharge ports of the left barrel and the right barrel are connected to a nozzle through a nozzle converter; the installation A first drive motor and a second drive motor are also fixed on the block, through the drive of the first drive motor and the second drive motor, the left barrel and the right barrel work alternately to realize the continuous extrusion of printing consumables from the nozzle . In the printing of high-viscosity paste consumables, for the 3D printing of large-volume objects, there is no need to stop midway and manually add materials, which reduces the labor intensity of operators.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a piston-type extrusion nozzle device capable of continuous work and a use method thereof. Background technique [0002] 3D printing technology has been born for more than 30 years. After a long period of development, especially in recent years, its technical superiority has initially emerged in many fields, and even plays an irreplaceable role in some fields. [0003] In the prior art, the nozzle devices used for 3D printing of paste-like consumables mostly use plunger-type nozzle devices. Since the paste-like consumables are not suitable for rolling into filaments, the continuous printing capability of the plunger-type nozzle devices is poor, and the printing volume is large. The applicability of volumetric objects is poor, and during the operation process, the operator has a high degree of participation in the whole process and the labor intensity is high. [0004] Domestic continu...
