Problems solved by technology

However, powder-formed green products (semi-finished products that have only been formed and have not been hardened) have low mechanical strength and are brittle, and are coated in unformed powder after forming. In this situation, the simple separation of green embryos and powder is a technical problem that must be solved
[0003] At present, the gypsum powder-based powder-type three-dimensional molding machine on the market uses a vacuum suction powder removal method. During the powder removal process, it is easy to cause damage to the finished product due to vacuum suction. On the other hand, this powder removal method requires Equipped with a loaded air pump, powder feeding pipeline and powder filtering mechanism, it is expensive and consumes energy

Abstract

A powder removal device for removing dust from a raw product printed by a 3D printer. A leak-proof plate capable of vertical movement is arranged in the printer, and the powder removal device includes a leak-proof plate installed on the leak-proof plate. A support device and a vibration module installed on the support device, the support device includes a platform for placing the green product, the platform is provided with a through hole for dust to pass through, the vibration module The group can drive the platform to vibrate so that the dust on the green product flows out from the through hole to the leakproof plate.

Description

technical field [0001] The invention relates to the field of printers, in particular to a powder removing device in a 3D printer. Background technique [0002] 3D printers are currently an industry that is actively developing around the world. Looking at the existing molding methods, only powder molding has the ability to colorize, and has the fastest molding speed, the lowest cost of consumables, and the smallest molding energy consumption. However, powder-formed green products (semi-finished products that have only been formed and have not been hardened) have low mechanical strength and are brittle, and are coated in unformed powder after forming. In this situation, it is a technical problem that must be solved to simply separate the green embryo from the powder. [0003] At present, the gypsum powder-based powder-type three-dimensional molding machine on the market uses a vacuum suction powder removal method. During the powder removal process, it is easy to cause damage ...
