Abstract

The invention discloses a blockage-proof material spray head for a 3D printer. The blockage-proof material spray head comprises a spray head body. The upper portion of the spray head body is cylindrical and the lower portion of the spray head body is conical. A feeding pipe is arranged at one side of the spray head body. A discharging outlet is formed in the bottom of the spray head body. A printed material flow channel is formed in the spray head body and further comprises a through flow channel body and a necking flow channel body. The side wall on the upper portion of the through flow channel body communicates with the feeding pipe, and the bottom end of the through flow channel body is connected with the necking flow channel body. The inner diameter of the necking flow channel body isgradually reduced, and the bottom end of the necking flow channel body is connected with the discharging outlet. A rotating shaft is arranged inside the through flow channel body, and a screw blade isarranged on the rotating shaft. A rotating motor is arranged at the top of the spray head body and is further connected with the rotating shaft in a transmission mode. The blockage-proof material spray head for the 3D printer is simple in structure and convenient to install, and printed materials can be effectively prevented from blocking the spray head.

Description

technical field [0001] The patent of the present invention relates to the field of 3D printing, in particular to an anti-clogging material nozzle for a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of accumulative 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 build the product layer by layer according to the program. The 3D printer nozzle is one of the components of the 3D printer. At present, the nozzles used in 3D printers are prone to clogging. Contents of the in...
