Powder heating assembly suitable for quick forming device and heating module of powder heating assembly

Abstract

The invention relates to a powder heating assembly suitable for a quick forming device. The powder heating assembly comprises a powder supply trough and a heating module, wherein the powder supply trough is provided with an accommodating space and a powder falling opening; the accommodating space is used for accommodating forming powder and is communicated with the powder falling opening; the heating module is arranged at the bottom of the powder supply trough and comprises a material discharging heat guide cover piece and a heat guide piece; the material discharging heat guide cover piece is arranged at the powder falling opening in a covering manner and is provided with a material outlet; the material outlet is communicated with the powder falling opening; the heat guide piece is arranged between the bottom of the accommodating space of the powder supply trough and the material discharging heat guide cover piece, and a heating unit is arranged in the heat guide piece; the heating unit is used for heating the heat guide piece, so that the forming powder at the bottom of the accommodating space of the powder supply trough can be preheated to eliminate humidity in the forming powder and form dry forming powder; the dry forming powder falls off through the material outlet for powder pavement.

Description

technical field [0001] The present invention relates to a powder heating assembly, in particular to a powder heating assembly and a heating module suitable for a rapid prototyping device, which can perform a preheating operation on the molding powder in a powder supply tank. Background technique [0002] Rapid prototyping technology (RP technology for short) is developed based on the concept of building a layer-by-layer stacking layer similar to a pyramid. Automatically and quickly convert the design scheme of any complex shape into a 3D solid model, which greatly shortens the development cycle of new products and reduces the cost of research and development, and can ensure the time to market of new products and the first-time success rate of new product development. Molding technology provides a more complete and convenient product design communication tool for technical personnel, as well as between technical personnel and enterprise decision makers, product users and othe...
