High-precision nail polish color matching instrument adapted to high viscosity

Abstract

The invention relates to a high-precision nail polish color matching instrument adapted to high viscosity. The high-precision nail polish color matching instrument comprises extruders and extruder heating devices located on the side faces of the extruders, wherein each extruder comprises a liquid storage chamber located in the upper portion, a high-pressure injection chamber is formed under each liquid storage chamber, and each high-pressure injection chamber is composed of a feeding one-way valve on the feeding portion, a high-pressure piston and a one-way valve on the discharging portion, wherein the color matching instrument is provided with three or more extruders, each extruder contains nail polish of different primary colors, each extruder can work independently to squeeze out nail polish of single color, multiple extruders can also correspondingly adjust data of the extruders according to the colors of the nail polish under the technical control of existing software, according to the color selected by a user, matching data of various primary colors needed by the color is searched for from a database, then the extruders of different primary colors are controlled to squeeze out a corresponding amount of nail polish to achieve color matching, thereby reducing the cost, and the high-precision nail polish color matching instrument can be used in batch production workshops, and can also used in nail salons on a small scale.

Description

technical field [0001] The invention relates to the field of nail polish color matching devices, in particular to a high-precision nail polish color matching device suitable for high viscosity. Background technique [0002] Nail polish is a common daily beauty product used to apply to fingernails or toenails for protection and aesthetics. At present, the common nail polish colors on the market are relatively fixed, which cannot meet the needs of users to change colors frequently. In response to this problem, Chinese invention patent CN105768497A discloses a self-coloring nail polish set, which includes a plurality of independently sealed packaging units, the packaging unit includes an outer wall and a cavity surrounded by the outer wall, and the self-coloring nail polish The set also includes a toning unit, and the toning unit includes a toning part and a storage part, and a toning brush is arranged in the storage part. The self-coloring nail polish set can realize the rap...

Problems solved by technology

[0004] 1. In order to make the color of the ratio the same as the actual color, each basic color needs to be extruded with high precision. In practice, an extrusion accuracy of 0.01ml is required, but the existing equipment cannot meet this accuracy requirement;

[0005] 2. Nail polish is a very viscous substance with extremely low fluidity. It is difficult to reach the extrusion cavity, and it is not easy to flow in the pipeline. During the extrusion process, it also requires a very large driving force , which reduces the extrusion speed and accuracy, and even cannot be extruded; and due to the high viscosity, after the nail polish is extruded, it will stick to the nozzle, causing it to fail to reach the collection box, thereby reducing the proportion of a certain color and making the color wrong
