3D printing material pretreatment device capable of improving smoothness

Abstract

The invention discloses a 3D printing material pretreatment device capable of improving smoothness. The 3D printing material pretreatment device comprises an outer box body, a rack, a motor, a first bevel gear, a second bevel gear and a hot melting box. A feeding inlet is formed in the top of the outer box body, and a collecting box is arranged in the outer box body. A fixing piece is mounted on the outer wall of the collecting box, and the rack is arranged on the outer wall of the fixing piece and connected with a first connecting gear in an engaged mode. A discharging pipe is arranged at thetop of a grinding box, and a through groove is formed in the discharging pipe. A pressing plate is connected to the outer wall of a reciprocating lead screw, and a pressing block is arranged on the pressing plate. According to the 3D printing material pretreatment device capable of improving smoothness, the through groove is formed in the discharging pipe, and the size of the through groove is matched with that of a groove in the bottom of the collecting box; and when the groove and the through groove are superposed, materials can fall, and when the groove and the through groove are staggered, the materials cannot fall, and thus, quantitative discharging of the materials can be achieved.

Description

technical field [0001] The invention relates to the technical field related to 3D printing materials, in particular to a 3D printing material pretreatment device capable of improving smoothness. Background technique [0002] 3D printing material is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing, currently in the fields of industrial design, architectural design, automobiles, aerospace In 3D printing, it is necessary to select printing materials according to actual needs, so there are many types of printing materials, such as polymer powder materials, paraffin powder materials, plastic materials, etc. There are many types, all printing materials are in It will be pre-treated before use to ensure the molding effect in the later stage, so the use of processing devices is essential. [0003] However, the existing 3D printing material pretreatment devices still have some short...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a 3D printing material pretreatment device that can improve the smoothness, so as to solve the problem that the 3D printing material pretreatment device currently on the market proposed by the above-mentioned background technology is inconvenient to clean the discharge pipe of the material. When the material is processed and discharged, it is easy to stick to other substances, which will cause lumps when the material is used later, which affects the printing effect and reduces the use efficiency of the processing device. Moreover, when the material is processed, it will need to Hot-melt, and before hot-melt, it is not convenient to roll the material, and the material that is not fully rolled is prone to uneven particles, and in the subsequent hot-melt, there will be uneven hot-melt, which will affect the quality of printing, thus Problems that reduce the availability of handling devices
