Cooling device of 3D printer

Abstract

The present invention provides a cooling device for a 3D printer, comprising a plurality of cooling fins evenly arranged on the outer wall of the nozzle of the 3D printer, a mounting plate arranged above the cooling fins and an air pipe capable of blowing air to the cooling fins, the mounting plate is fixedly connected to the nozzle, The air pipe is installed on the mounting plate; the cooling device of the present invention includes an air pipe and an air pump connected to the air pipe without a fan, so the vibration problem of the extrusion nozzle caused by the rotation of the fan can be effectively avoided; the outer wall of the nozzle is evenly provided with a number of cooling fins, The outlet of the air pipe blows air to the heat sink to further improve the heat dissipation effect, and the heat dissipation effect is uniform, ensuring the same cooling degree of local raw materials, avoiding the problem of uneven material extrusion caused by uneven cooling of the nozzle; at the same time, the device has a simple structure and low cost. Also quite cheap.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a cooling device for a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a machine 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. It is a cumulative manufacturing technology that creates three-dimensional objects by printing layers of adhesive materials. The basic principle is that by putting data and raw materials into the 3D printer, the machine will build the product layer by layer according to the program, and The product is printed out and ready for immediate use. 3D printers used to be used to make models in the fields of mold making, industrial design, etc., and are now gradually being used for direct manufacturing of some products, which can be used in jewelry, foo...

AI Technical Summary

Problems solved by technology

[0004] However, during the rotation of the cooling fan, it is easy to cause the extrusion nozzle to vibrate, which will cause ripples on the surface of the printed model, which will affect the printing accuracy. At the same time, the fan’s air supply range is too large, which will also cause the extrusion nozzle to cool down and cause uneven material extrusion. problems, which will adversely affect the final printing effect
