Embodiment Construction

[0027] The embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0028] See Figure 1-10 The intention of this embodiment is to irradiate real-time curing light at the tip of the nozzle under the condition that the nozzle is small in size and high in light curing efficiency. Since the dispensing needle 5 at the tip of the nozzle has different specifications, the length of the dispensing needle 5 of different specifications is different, so the position of the material extrusion will change with the change of the length of the dispensing needle 5, which means four The focal point of the laser beam emitted by the laser point light source 16 after being reflected by the laser reflection lens can change with the change of the length of the dispensing needle 5. In order to achieve the above-mentioned purpose, this embodiment designs three structures of the light curing nozzle housing 1, the barrel part, the point light source part,...

Abstract

The invention discloses a rapid photocuring spray head for a 3D printing device. The spray head mainly comprises a photocuring spray head shell, a charging barrel part, a point light source part and a reflector angle frame lifting part. The charging barrel part mainly comprises a charging barrel, an adhesive dispensing needle connected to the bottom end of the charging barrel, and a charging barrel cover arranged at the top end of the charging barrel. The point light source part mainly comprises laser point light sources, a light source fixing frame, a reflector fixing frame and reflector angle frames. The reflector angle frame lifting part mainly comprises a lead screw, an adjustment rotary knob, a slideway, a sliding block and a nut. The photocuring spray head has the advantages of being small and exquisite in structure and high in photocuring efficiency. Due to the fact that the high-power laser light sources are arranged in the spray head, laser light is converged at the position of a discharge outlet of the spray head through the reflection of reflectors. In this way, it is guaranteed that high-power laser with the corresponding wavelength is available for radiation at the discharging moment, and rapid curing of photocuring materials is achieved.

Description

Technical field [0001] The invention belongs to the technical field of 3D printing equipment, and relates to a fast light curing nozzle used for 3D printing equipment. Background technique [0002] 3D printers are rapid prototyping equipment that has emerged in recent years. When printing with a 3D printer, you must first slice the 3D model with software to form a series of digital slices. Then the 3D printer stacks the raw materials layer by layer according to the slice information until a solid object is formed. The 3D printer print nozzle is the part where the 3D printer extrudes the material and is the core part of the 3D printer. According to the different properties of the material, printing different materials requires different conditions, such as high temperature and low temperature. This requires the print nozzles of 3D printers to meet these special printing conditions, such as high-temperature nozzles that can produce high temperatures, and low-temperature nozzles ...
