Self-heat-dissipation type 3D printing double nozzles

Abstract

The invention discloses self-heat-dissipation type 3D printing double nozzles, and relates to the field of 3D printing. The self-heat-dissipation type 3D printing double nozzles comprise a heat dissipation shell body, a first throat pipe, a second throat pipe, a heating shell body, a first nozzle body, and a second nozzle body. The outside of the heat dissipation shell body is provide with a plurality of fins, the upper end face and the lower end face of each fin are provided with heat dissipation plates with inclined planes, and the upper end of the heat dissipation shell body is provided with a disk-divided device; the lower end of the heating shell body is provided with the first nozzle body and the second nozzle body, the first throat pipe and the second throat pipe sequentially penetrate through the disk-divided device, the heat dissipation shell body and the heating shell body from top to bottom, the lower end of the first throat pipe is arranged at an entrance of the first nozzle body, and the lower end of the second nozzle is arranged at an entrance of the second nozzle body. The self-heat-dissipation type 3D printing double nozzles have a heat dissipation function, products printed are provided with coating materials and core materials, strength of the products is greatly enhanced, at the same time, different nozzles are switched according to different colors of the products, and printing efficiency is enhanced.

Description

Problems solved by technology

However, if the temperature of the nozzle is too high, it will cause other parts to dissolve and burn. Therefore, a cooling 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, but the cooling fan installed in this way can only Heat dissipation at one position of the nozzle, resulting in uneven heat dissipation, which affects the effect of heat dissipation, and requires an external circuit to supply power to the electric fan
