Embodiment Construction

[0014] A 3DP color three-dimensional printer powder recovery device, the device includes: a computer, a powder recovery tank parallel to the forming platform, a dust reduction net is arranged at the notch of the recovery tank, a powder rotary fan and a powder rotary fan are arranged directly below the dust reduction net. The fan rotates under the control of the stepping motor. There are curved slide plates on both sides of the powder rotating fan. Under the control of the computer, the stepping motor controls the powder rotating fan to form 120-degree fan blades. The notch of the recovery tank is facing directly, and keeps a distance of 1mm from the arc-shaped sliding plate. The arc-shaped powder sliding plate is connected to the notch, and the bottom is connected to the recovery powder pipeline. Right below the powder pipeline is the powder recovery box.

[0015] The powder recovery device with powder fan and arc-shaped slide plate structure greatly improves the environment of...

Abstract

A powder recovery device for a 3DP color three-dimensional printer, including a powder recovery tank connected side by side with a molding tank, a dust-reducing net is arranged at the slot, and a powder rotating fan is placed under the dust-reducing net, and the powder rotating fan is controlled by a stepping motor , There are arc-shaped powder sliding plates on both sides of the powder fan, and the powder sliding plate is connected to the recovery port for powder recovery. Right below the recovery port is the powder recovery box, and the recovered powder can be reused. This device is suitable for various 3DP process molding devices. The powder rotating fan and arc-shaped sliding powder plate can make the powder recovery have a good effect of dust reduction and dust prevention. The powder recovery speed is fast and will not cause powder clogging. recycling channel.

Description

Technical field: [0001] The invention belongs to the field of 3DP color three-dimensional printers, in particular to the field of powder recycling devices for 3DP color three-dimensional printers. Background technique: [0002] Rapid prototyping technology is a method to realize computer three-dimensional graphics into physical entities. It is based on modern CAD technology, computer control technology, precision servo drive technology, material science, etc., and can produce various objects with very complex shapes. The commonly used processes of rapid prototyping technology include photocuring, selective laser sintering, fused filament deposition production, laminated solid production and three-dimensional printing, etc. The above rapid prototyping technologies, the first four in terms of color, can only produce monochrome thing. Color 3D printing uses rapid prototyping and micro-droplet injection molding technology to produce layer by layer, and finally can realize color...
