Spray head heat dissipating mechanism for 3D printer

Abstract

The invention discloses a spray head heat dissipating mechanism for a 3D printer. The spray head heat dissipating mechanism comprises a 3D printer body, a spray head seat is arranged in the 3D printerbody and arranged at the top of the 3D printer body, a spray head is installed on the lower surface of the spray head seat, a heat dissipating pipe is connected to the outer side of the spray head ina sleeving mode, the top of the heat dissipating pipe is welded to the lower surface of the spray head seat, the bottom of the spray head penetrates through the heat dissipating pipe, a cooling waterpipe is arranged in the spray head seat and the heat dissipating pipe, the two ends of the water cooling pipe penetrate through the spray head seat and one side of the heat dissipating pipe respectively, a first rubber water pipe is arranged at the bottom end of the cooling water pipe in a communicating mode, and a first water pipe is arranged at the other end of the first rubber water pipe in acommunicating mode. According to the spray head heat dissipating mechanism, the cooling water pipe is arranged on the outer side of the spray head, and water at the bottom of a water tank is pumped out through a water pump; and when water passes through the cooling water pipe, water flow in the cooling water pipe brings heat on the outer side of the spray head away, and thus heat dissipating handling can be carried out on the spray head conveniently.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, in particular to a nozzle cooling mechanism for 3D printers. Background technique [0002] D printer, also known as three-dimensional printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond materials, which create three-dimensional objects by printing layers of adhesive materials. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will manufacture products layer by layer according to the program. [0003] At present, there are some problems in the existing 3D printers after use: because the temperature at the nozzle is too high, if the temperature at the nozzle is not cooled...
