An Angle Adjustable Dual Light Source Inkjet Printing Nozzle

Abstract

The invention discloses a double-light-source ink jetting type printing sprayer with the adjustable angle. The double-light-source ink jetting type printing sprayer comprises an ink jetting type sprayer body, two light sources, two light source clamps, four set screws and an integral sprayer frame. The integral sprayer frame is integrally in an arc shape and comprises an installing plate, two arc slide ways and a sprayer light shield. An opening of the ink jetting type sprayer body faces downwards, the ink jetting type sprayer body can jet light curing materials, the two light sources are symmetrically arranged on the two sides of the ink jetting type sprayer body, light rays are gathered to a light source focus point under the sprayer body, and the materials jetted by the ink jetting type sprayer body fall to the position of the light source focus point to be cured and formed. The incidence angle of the two light sources can be independently adjusted and ranges from 30 degrees to 60 degrees, the angle of the light sources is adjusted, and the position of the light source focus point is not changed. The flexibility of the technology is improved through the adjustable light source incidence angle; the forming technology performance and the printing efficiency are improved through the two light sources symmetrically arranged; and by means of the sprayer light shield, the probability of the blockage of the sprayer can be greatly reduced.

Description

Technical field: [0001] The invention belongs to the fields of light-curing 3D printing and 3D bioprinting, and in particular relates to an angle-adjustable dual-light source inkjet printing nozzle. Background technique: [0002] Since the advent of 3D printing technology, the printing method of photo-curing molding has been used, which uses the principle that photo-curable materials undergo polymerization reactions to form solids or gels under light of specific wavelengths. The traditional photo-curing forming generally adopts the method of scanning galvanometer. Its disadvantage is that the forming is scanning in the solution pool by light, which requires a large amount of prepolymer materials. Secondly, the traditional method can only be formed in a fixed solution pool, and the equipment is very bulky, and the cost of the scanning galvanometer is also high. [0003] If the existing ink-jet photocuring method uses a single light source for irradiation, not only the curing...

AI Technical Summary

Problems solved by technology

The traditional photo-curing forming generally adopts the method of scanning galvanometer, and its disadvantage is that its forming is scanned in the solution pool by light, which requires a large amount of prepolymer materials

Secondly, the traditional method can only be formed in a fixed solution pool, and the equipment is very bulky, and the cost of the scanning galvanometer is also high

[0003] If the existing inkjet photocuring method uses a single light source to irradiate, not only the curing speed is slow, but also the energy of the spot will be uneven.

And the light source with a fixed position is not adjustable enough in the actual printing process

In addition, once the reflected processing light is reflected on the nozzle during the printing process, the photocurable material will be cured at the nozzle, resulting in frequent blockage of the nozzle
