Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0028] Such as Figure 1-5 As shown, a rotary 3D printing head includes a supporting mechanism, a rotating mechanism, a nozzle mechanism and a blocking mechanism;

[0029] The support mechanism includes a support plate 1, a support rod 2 and a cylinder 3, the support plate 1 is arranged horizontally, the support rod 2 is vertically arranged on the lower end surface of the support plate 1, and the cylinder 3 is arranged on the bottom of the support rod 2 At the bottom, the output shaft of the cylinder 3 is set vertically downward, and the strut 2 is connected with the blocking mechanism through the cylinder 3;

[0030] The rotating mechanism includes a sleeve...

Abstract

The invention relates to a rotary type 3D printing head which comprises a supporting mechanism, a rotating mechanism, spray nozzle mechanisms and a shading mechanism, wherein the supporting mechanism comprises a supporting plate, a supporting rod and a cylinder; the rotating mechanism comprises a sleeve, a first motor, a first circular gear, a second circular gear and limiting rings; the spray nozzle mechanisms comprise spray nozzles, heating blocks, material feeding pipes and connection rods; the shading mechanism comprises a baffle and a collection chamber; a material feeding mechanism comprises a material feeding plate, a second motor and a third circular gear; a heat dissipation mechanism comprises a coil pipe, a water tank and a water pump. The rotary type 3D printing head is provided with four spray nozzle mechanisms, so that four raw materials can be put into the printing head at the same time; during printing, switching of the different raw materials can be realized; during switching of the different raw materials, the raw materials leaking from the spray nozzles can be led into the collection chamber, so that the printing quality is guaranteed; furthermore, a water cooling heat dissipation mechanism is arranged outside the material feeding pipes, so that noise is reduced, and interference of air to the printing head during heat dissipation of a conventional fan is further prevented.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a rotary 3D printing head. Background technique [0002] With the development of science and technology, 3D printing technology has been applied in many fields such as jewelry, footwear, industrial design, automobile, etc. 3D printer is a machine of rapid prototyping technology, which is based on a digital model file, using Bondable materials such as powdered metal or plastics are used to construct objects by layer-by-layer printing. [0003] At present, the 3D printing head is the key component of the 3D printer. It is set on the stable walking mechanism and is used to melt and extrude the raw materials. Most of the existing 3D printing heads only have one nozzle, and some complex printing that requires different materials will use a 3D printing head with multiple nozzles. When switching, the remaining raw materials in the nozzles often drip, which seriously affects the pr...
