Sand cleaning and part-taking device of 3D printer

Abstract

The invention provides a sand cleaning and part-taking device of a 3D printer, relates to the technical field of 3D printers, and solves the problems that wind power cleaning and vibration type cleaning of sand on parts cannot be realized through linkage while the parts are taken out through structural improvement, and multiple protection of a sliding part cannot be realized through structural improvement. The sand cleaning and part-taking device of the 3D printer comprises a shell, and the shell is of a concave structure. Due to the fact that an elastic telescopic rod A is welded to the inner wall of the shell, and the head end of the elastic telescopic rod A is elastically connected to a through hole in a clamped mode so that when a placing plate is pulled, continuous vibration of the placing plate can be achieved through cooperation of the head end of the elastic telescopic rod A and the through hole, then sand on the parts can be shaken off, and the head end of the elastic telescopic rod A is matched with the through hole so that the placing plate can be elastically locked.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and more specifically relates to a device for removing sand from a 3D printer. Background technique [0002] Three-dimensional printing technology is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Currently, 3D printers are used in When making sand tables or some molds, fine sand is often adhered to the surface of the printed product. [0003] For example, the application number: CN202021155618.2, relates to the technical field of 3D printers, and discloses a 3D printer sand removal device, including a base and a sand removal box, and a support rod is fixedly installed on the left side of the top of the base, and the support rod A powder bed is hinged at the top, a first cylinder is fixedly installed on the top of the base, a motor is fixedl...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a 3D printer sand removal device to solve the existing problem that the existing device needs to be manually cleaned when cleaning the sand on the parts, and cannot be taken out through structural improvement. The simultaneous linkage of the parts realizes the wind cleaning and vibrating cleaning of the sand on the parts; moreover, the placement plates of the existing devices generally adopt a sliding structure to realize pulling, but the sliding part is easy to get stuck in the sand, and does not The problem of being able to achieve multiple protections for sliding parts through structural improvements
