Problems solved by technology
Usually, in order to keep the wire material to be melted quickly, it is usually necessary to heat the nozzle to a high temperature through an aluminum heating block, because the heat head and the throat are connected together, and the heat of the nozzle will be conducted to the far end through the throat, causing the wire material to overheat. early melting
However, the prematurely melted wire material cannot transmit the extrusion force of the feeding teeth, resulting in the print head not being able to extrude the printing material, so it is necessary to install a cooling device on the throat part

The device is used for cooling a throat pipe and a nozzle of the 3D printer hot head; the cooling device comprises a throat pipe cooling part and a nozzle cooling part, wherein the throat pipe cooling part is installed on the outer side of the throat pipe of the 3D printer hot head, and the nozzle cooling part is installed on the outer side of a nozzle of the 3D printer hot head; the throat pipe cooling part comprises a cooling upper cavity, a cooling lower cavity, a throat pipe copper sleeve, a flow regulating plate and cooling fins; the nozzle cooling part comprises an omni-directional air cooling heat dissipation ring pipe arranged on the outer side of the nozzle of the 3D printer hot head.The high-efficiency energy-saving cooling device of the 3D printer hot head has the advantages of being simple in structure, small in size, good in heat dissipation and cooling effect, and low in energy consumption.
Description
technical field [0001] The invention relates to a high-efficiency and energy-saving thermal head cooling device for a 3D printer. Background technique [0002] The melt extrusion 3D printer is a device that heats the melting point PLA or melting point ABS wire to a molten state, extrudes through the feed tooth, extrudes through the nozzle, and stacks it in a certain shape to form a printed part. Usually, in order to keep the wire material to be melted quickly, it is usually necessary to heat the nozzle to a high temperature through an aluminum heating block, because the heat head and the throat are connected together, and the heat of the nozzle will be conducted to the far end through the throat, causing the wire material to overheat. Melt early. However, the prematurely melted wire material cannot transmit the extrusion force of the feeding teeth, resulting in the print head not being able to extrude the printing material, so it is necessary to install a cooling device in ...
