Powder filtering system and self cleaning assembly thereof

Abstract

The invention relates to a powder filtering system which is used for sucking and filtering powder flying when a three-dimensional molding mechanism operates. The powder filtering system comprises a casing, a powder filtering element, a recovery construction member and an air sucking device, wherein the casing is provided with a sucking port, a first space and a second space communicated with the first space, and the sucking port is connected with the space. The powder filtering element is arranged in the first space and provided with a self cleaning assembly, the recovery construction member is arranged in the second space, the air sucking device is communicated with the first space to enable the first space to form a negative pressure state and produce sucking force to lead powder sucked form the sucking port in the second space, then the powder is transmitted to the powder filtering element to filter and block, and the self cleaning assembly can shake the powder adhered to the powder filtering element to recover the blocked powder to the recovery construction member.

Description

technical field [0001] The invention relates to a powder filtering system and its automatic cleaning component, especially a powder filtering system and its automatic cleaning component suitable for a three-dimensional forming mechanism. Background technique [0002] Rapid Prototyping (RP technology for short) is a technology derived from the concept of building a pyramid layer by layer, which can quickly and cost-effectively shape the designer's idea in a short time and present it to the public , its main feature is the quickness of forming, which can automatically and quickly convert the design scheme of any complex shape into a 3D solid model without any tools, molds and jigs, which greatly shortens the development of new products. cycle and reduce R&D costs, and can ensure the time to market of new products and the success rate of new product development at one time. A complete and convenient product design communication tool, thus significantly improving the competitiv...

AI Technical Summary

Problems solved by technology

[0006] The main purpose of the present invention is to provide a powder filtration system to solve the problem that the dust raised by the known floor-standing three-dimensional molding device will pollute the working environment when spreading powder, printing and taking out molded products, and must rely on frequent manpower. Inadvertently perform vacuuming and cleaning maintenance work, the molded product will be damaged due to carelessness in the cleaning process, or the components of the three-dimensional forming device will be damaged, resulting in the failure of the three-dimensional forming device to operate normally and waste of manpower and time.
