Description

Technical Field

[0001] The utility model relates to the technical field of material mixing, in particular to a photosensitive resin mixing device. Background Art

[0002] Photosensitive resin, commonly known as UV curing glue, or UV resin (glue), is mainly composed of polymer monomers and prepolymers, in which photoinitiators, or photosensitizers, are added. When exposed to ultraviolet light of a certain wavelength, it will immediately cause a polymerization reaction and complete the solidification conversion; in the past two years, photosensitive resin has been used in the emerging industry of 3D printing, and has been favored and valued by the industry because of its excellent properties.

[0003] Different photosensitive resins have different characteristics and application scopes. Common ones include epoxy resin, acrylic resin, phenolic resin, etc. Among them, epoxy resin has excellent mechanical properties and chemical stability, and is suitable for fields that require high strength and high corrosion resistance; acrylic resin has the characteristics of fast curing, low viscosity and high transparency, and is suitable for fields that require high precision and high transparency; phenolic resin has good heat resistance and corrosion resistance, and is suitable for applications in harsh environments such as high temperature, high pressure, strong acid, and strong alkali; in some specific application scenarios, different types of photosensitive resins may need to be mixed. For example, in order to achieve specific optical properties or develop new materials, different photosensitive resins need to be blended.

[0004] When mixing two or more resin materials, they need to be physically dissolved or dispersed in each other to obtain a new material with specific properties and characteristics. In actual operation, in order to avoid incompatibility between different types of photosensitive resins selected, the properties of the photosensitive resins are tested before mixing to ensure that the two or more resins are compatible. However, there are still differences in the material composition of photosensitive resins of different brands or models, so they are not so easy to dissolve in each other, which can easily cause the operator to mix two or more resin materials. The mixed product obtained has deficiencies in quality and performance, which in turn affects the quality of the final printed product, as well as its physical and chemical properties.

[0046] The heat-drying mechanism 5 is suitable for being close to the first transfer dish 3 and self-heating, so that the internal and external temperatures of the first transfer dish 3 are increased. The photosensitive resin mixing device can carry the resin material to rapidly reciprocate along the frame 1 in the vertical direction through the vertical shaking part 2, thereby causing the resin material to tumble violently inside the vertical shaking part 2, and then causing the resin materials to rub and diffuse with each other on a large scale, thereby achieving preliminary mixing of the resin materials; the resin material can be regularly flipped from bottom to top in the first transfer dish 3 through the stirring part 4, thereby causing the resin material to continuously tumble and roll, and further achieving mutual fusion between the resin materials; the heat-drying mechanism 5 can flip the resin material while the stirring part 4 is flipping it.
