Embodiment 1

[0026] Such as figure 2 , Figure 5 , Figure 7 Shown is a structure of the powder feeding device of the present invention. The powder feeding roller (2) provided with 6 powder feeding grooves (21) is installed in the through hole (11) of the powder feeding outer frame (1) provided with the connection device (13), and the powder feeding roller (2) has two One group of sealing rings (23), sealing gasket (24), bearing (3) and end cover (4) are installed on the end, and are fixed on the two ends of the powder feeding outer frame (1) with screws. The powder enters from the powder feeding groove (12) above the powder feeding frame (1), then flows into the powder feeding groove (21) of the powder feeding roller (2), and is rotated to the powder feeding groove ( 12) Falling, so circular rotation to feed powder.

Embodiment 2

[0028] Such as Figure 4 , Figure 5 , Figure 7 Shown is a structure of the powder feeding device of the present invention. The powder feeding roller (2) with 6 powder feeding grooves (21) is installed in the through hole (11) of the powder feeding outer frame (1), and a set of sealing rings ( 23), the gasket (24), the bearing (3) and the end cover (4), are fixed on both ends of the powder feeding outer frame (1) with screws. The powder enters from the powder feeding groove (12) above the powder feeding frame (1), then flows into the powder feeding groove (21) of the powder feeding roller (2), and is rotated to the powder feeding groove ( 12) Falling, so circular rotation to feed powder.

Embodiment 3

[0030] Such as figure 2 , Image 6 , Figure 7 Shown is a structure of the powder feeding device of the present invention. The powder feeding roller (2) with 3 powder feeding grooves (21) is installed in the through hole (11) of the powder feeding outer frame (1) with the connection device (13), and the two ends of the powder feeding roller (2) A group of sealing rings (23), sealing pads (24), bearings (3) and end caps (4) are installed in cooperation, and are fixed on the two ends of the powder feeding outer frame (1) with screws. The powder enters from the powder feeding groove (12) above the powder feeding frame (1), then flows into the powder feeding groove (21) of the powder feeding roller (2), and is rotated to the powder feeding groove ( 12) Falling, so circular rotation to feed powder.

Abstract

The invention discloses a powder feeding device for additive manufacturing equipment and the additive manufacturing equipment with the powder feeding device. The power feeding device comprises a powder feeding outer frame, a powder feeding roller, a bearing and an end cover. The technical scheme is characterized in that the powder feeding roller is arranged in the integral powder feeding outer frame, and the characteristics of normally feeding powder and preventing leakage when powder is not fed can be realized without aligning the positions of a powder feeding groove and a powder passing groove during powder feeding, so that reliability and efficiency of continuous powder feeding are improved; and meanwhile, machine maintenance cost can be reduced, and equipment operation reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of laser forming, and in particular relates to a powder feeding device for additive manufacturing equipment and additive manufacturing equipment with the powder feeding device. Background technique [0002] Selective laser sintering (SLS) uses powder materials, including metal powder or polymer materials such as nylon powder. The basic process is: the powder supply device sends a certain amount of powder to the working platform of the molding cylinder, the powder spreading device spreads the powder on the plane of the working platform on the upper layer of the working surface in the molding cylinder, and the heating device heats the powder to the working platform of the molding cylinder. At a certain temperature, the laser galvanometer control system controls the laser to scan the powder in the cross-sectional profile of the layer, so that these powders are melted and sintered with the formed part below; whe...
