Description

Technical Field

[0001] This utility model relates to the field of additive manufacturing technology for granular materials, and in particular to a rapidly changeable nozzle structure for additive manufacturing of granular materials. Background Technology

[0002] Additive manufacturing involves the layer-by-layer deposition of materials. The nozzle shape has a significant impact on material flowability, printing accuracy, interlayer bonding strength, surface quality, and application areas during the additive manufacturing process. Selecting a suitable nozzle shape is crucial for optimizing the manufacturing process and improving product quality and production efficiency. Existing nozzle structures require dedicated machines for use, resulting in poor performance and failing to meet the needs of long-term enterprise development.

[0003] In view of the above, it is necessary to improve the existing nozzle structure to adapt to the current needs of nozzle replacement. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rapidly changeable nozzle structure for additive manufacturing of granular materials, including an upper turntable, a transfer platform disposed on the upper turntable, a lower turntable disposed below the transfer platform, a connecting rod disposed between the upper and lower turntables, a plurality of nozzle mounting holes arranged in a circumferential array on the lower turntable, and a plurality of nozzles disposed in the nozzle mounting holes. A feed pipe is installed on the transfer platform. The upper turntable is fixed and connected to the lower turntable through the connecting rod. The upper turntable is provided with a through hole, and the transfer platform is directly opposite the through hole on the upper turntable.

[0005] As a further addition to this technical solution, the feeding pipe is arranged vertically.

[0006] As a further addition to this technical solution, the bottom of the upper turntable and the lower turntable are hemispherical.

[0007] As a further addition to this technical solution, the upper turntable and the lower turntable are arranged at an angle.

[0008] As a further supplement to this technical solution, the nozzle mounting hole is a threaded hole.

[0009] As a further supplement to this technical solution, the nozzle mounting hole is provided with three holes.

[0010] As a further supplement to this technical solution, the nozzles are respectively circular nozzles, rectangular nozzles, and elliptical nozzles.

[0011] Its advantages lie in its simple structure and the ability to quickly change nozzles during the additive manufacturing process of granular materials. Attached Figure Description
