Abstract

The invention provides a melt deposition type 3D printer spray head cooling device which comprises a spray head hot end assembly, the hot end assembly is connected with a venturi assembly through a threaded structure, the venturi assembly is connected with a venturi cooling assembly through a threaded structure, the venturi cooling assembly is connected with a wire feeding mechanism through a fixing frame, the venturi cooling assembly is connected with a refrigerating device through a first cooling pipe connector and a second cooling pipe connector, and a control device is connected with the spray head hot end assembly through a power line. Work of the melt deposition type 3D printer spray head cooling device includes the steps of (1), selection of a PTC heater; (2), installation of the PTC heater; (3), injection of high-temperature conduction oil; (4), injection of heat-exchange liquid; (5), adjustment of a feeding wheel assembly; (6), start of a refrigeration device; (7), start of a venturi temperature sensor; (8), start of the PTC heater; (9), start of a 3D printer; (10), monitoring of material wire temperature; (11), temperature control over the venturi assembly; and by means of the melt deposition type 3D printer spray head cooling device, constant-temperature melting of the material wire in a spray nozzle and self-cooling of the material wire in a heat dissipation body can be achieved.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a nozzle cooling device of a fused deposition type 3D printer. Background technique [0002] Fused deposition 3D printing technology is a kind of rapid prototyping technology. Its basic working principle is to process the three-dimensional product model established in the computer in layers to obtain several two-dimensional plane graphics, and then use the wire feeding mechanism of the nozzle to transfer the thermoplastic material Send it to the nozzle and heat it to a molten state. Then, according to the contour information of the two-dimensional plane figure, under the control of the computer, the molten material is extruded from the tiny holes of the nozzle to print these two-dimensional plane figures layer by layer. After layer-by-layer stacking Form a three-dimensional solid model. [0003] During the working process, the nozzles of 3D printers are often clo...
