Problems solved by technology

Existing 3D printers all use fixed-caliber nozzles to print the target model, but the shape and size of each area of ​​the target model are different, and the fixed-caliber nozzles cannot make adaptive adjustments according to changes in the printing area, making existing 3D printers The printing speed and the display of model details can only compromise with each other and cannot achieve mutual satisfaction

Abstract

The invention discloses a 3D printer spray head with an adjustable nozzle caliber. The 3D printer spray head comprises a rotor and a nozzle assembly; the rotor comprises a heat storage block, a material storage pipe, a throat pipe, a heat insulation gasket, screws and nuts; the nozzle assembly comprises a first gasket, nozzle surrounding sheets, a second gasket, a guide plate and a control plate.The nozzle surrounding sheets are matched with one another to form a polygonal nozzle flow channel, and a guide groove for guiding the movement of the nozzle surrounding sheets is arranged on the guide plate to guide the movement direction of the nozzle surrounding sheets. The control panel is matched with the guide plate, and the relative rotation between the control panel and the guide plate canchange the size of the side length of the polygon enclosed by the nozzle surrounding sheets, thus realizing an adjustable size of the printing nozzle circulation area. The heat storage block is connected with the material storage pipe through screws and nuts, so that the heat transfer resistance between the heat storage block and the material storage pipe can be effectively improved.

Description

technical field [0001] The invention relates to a 3D printer, in particular to a 3D printer nozzle with adjustable nozzle diameter. Background technique [0002] A 3D printer is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is a machine that uses special wax, powdered metal or plastic materials to manufacture three-dimensional objects based on digital model files. [0003] Among them, the printer using the principle of fused deposition (FMD) and fused filament manufacturing (FFF) is to introduce the molten material in the molten material cavity into the specific position of the model through the nozzle under the action of the pressure in the molten material cavity and cool it naturally or forcedly. It solidifies into a solid state, and the diameter of the nozzle determines the minimum cross-sectional area of ​​the model and the maximum layer thickness that the printer can print. A nozzle with a smaller diameter can print a sma...
