Nozzle heat dissipation device of 3D printer

Abstract

The invention discloses a heat dissipation device for a nozzle of a 3D printer, which belongs to the technical field of 3D printing. The invention has a simple structure and can prevent vibration from affecting the molding quality of the 3D printer during the operation of the cooling fan. The cooling fan is arranged on the outside of the nozzle fixedly connected with the support of the 3D printer. The nozzle cooling device of the 3D printer also includes a connecting plate, an elastic rubber block and two wind collecting plates. The connecting plate is vertically arranged, and the connecting plate The upper end is fixedly connected with the bracket of the 3D printer, the elastic rubber block is arranged between the heat dissipation fan and the connection plate, the heat dissipation fan, the elastic rubber block and the connection plate are connected by bolts, and the air outlet of the heat dissipation fan is fixed on both sides Two wind gathering boards, the two wind gathering boards are arranged obliquely, and the included angle between the two wind gathering boards is an acute angle. The elastic rubber block of the present invention plays the role of shockproof, and prevents the vibration of the cooling fan from affecting the molding quality of the 3D printer during the printing process.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a nozzle cooling device of a 3D printer. Background technique [0002] As one of the core components of the 3D printer, the nozzle of the 3D printer largely determines the quality of the molding. The smoothness of the filament flowing out of the extrusion nozzle and the temperature of the filament directly affect the accuracy of 3D printing. However, if the temperature of the nozzle is too high, other components will be dissolved and burned, so a heat dissipation device is required to control the temperature of the nozzle within a certain range. At this stage, a cooling fan is usually installed at the nozzle. During the printing process, the vibration generated by the cooling fan operation will affect the molding quality of the 3D printer. Contents of the invention [0003] In view of the above problems, the present invention provides a nozzle cooling device f...
