Problems solved by technology

The working effect of the existing cooling device is not very satisfactory. One is that the cooling range is too large, resulting in different cooling degrees of raw materials at different positions. The other is that the 3D printer, especially the extrusion nozzle, will be caused by the working of the cooling device. Vibration, which in turn affects the uniformity of the raw materials extruded by the extrusion device, and affects the quality of the 3D model

Abstract

The invention discloses a cooling device of a 3D printer. The device comprises an annular member; and the annular member includes an annular upper part and an annular lower part. A hollow annular cavity is arranged in the annular upper part; annular side wall of the annular upper part is symmetrically distributed with a plurality of upper air inlets; the lower end of the annular upper part is provided with a plurality of annular upper air outlets; and a plurality of the annular gas paths in inverted trapezoid are arranged in the annular upper part. The upper end of the annular lower part is provided with a plurality of lower air inlets; each lower air inlet aligns with one upper air outlet, so that the annular cavity is in gas communication with a plurality of annular gas paths. The device also comprises an air pump. The annular member surrounds the outer side of an extrusion nozzle. The annular cavity in the invention plays a role of buffering to reduce vibration of gas jet; and the inside of the annular lower part is provided with a plurality of concentric annular gas paths to ensure that the cooling range is a uniformly distributed region centered by the extrusion nozzle, ensure same cooling degree on the local raw materials and avoid vibration on the extrusion nozzle.

Description

technical field [0001] The invention relates to a 3D printer technology, in particular to a cooling device for a 3D printer. Background technique [0002] In 3D printing technology, the extrusion equipment extrudes the raw material layer by layer according to the set path to build a three-dimensional model. In this process, as the raw material is extruded, it needs to be cooled at the same time, so that the raw material can be cooled and formed as soon as possible. . The working effect of the existing cooling device is not very satisfactory. One is that the cooling range is too large, resulting in different cooling degrees of raw materials in different positions. The other is that the 3D printer, especially the extrusion nozzle, will be caused by the working of the cooling device. Vibration, which in turn affects the uniformity of the raw materials extruded by the extrusion device, affects the quality of the three-dimensional model. Contents of the invention [0003] In ...
