The spectrocolorimeter 5 according to the embodiment of the present application preferably uses a Color-Eye spectrocolorimeter, and operates by measuring reflected light or transmitted light in the entire spectrum and generating a visual curve for describing the Color on a specific substrate under specific illumination conditions. Color-Eye spectrophotometers are capable of accurately analyzing Color because they can measure the visible spectrum range from 360nm to 750nm in units of wavelengths of every 10nm and provide specular reflection element and transmission mode measurements. The optical principle utilized by Color-Eye spectrophotometers is scattering/8 ° (illumination/measurement), which design enables it to accurately measure various properties of Color, including hue, brightness and saturation. The reflectance curve of a white surface is a straight line and the reflectance is approximately between 90% and 100%. The reflectance curve of the black surface is flat and the reflectance is close to 0%. While the reflectivity of the other colors peaks over the wavelength range of the light that it reflects most. This measurement is based on the physical properties of the colors, and by analyzing the reflected or transmitted light, the spectrophotometer 5 can quantify the color differences, thereby helping the user to perform accurate color management and quality control.
In this embodiment, after analyzing and confirming the color number of the target production color sample, the spectrocolorimeter 5 inputs the color number information to the control mechanism 6, and the control mechanism 6 determines (automatically outputs) the blanking ratio of the color master batches of the three colors of red, yellow and blue according to the color number information, thereby controlling the rotation speed of the three second metering pumps 23 (volumetric metering pumps) and accurately calculating the blanking amount of each component. For example, the Color-Eye spectrophotometry detects a green No. 1 sample Color, the control mechanism 6 controls the blue master batch and the yellow master batch to be mixed according to a ratio of 1:1, the Color-Eye spectrophotometry detects a green No. 2 sample Color, the control mechanism 6 controls the blue master batch and the yellow master batch to be mixed according to a ratio of 1:1.5, the Color-Eye spectrophotometry detects a rose No. 1 sample Color, the control mechanism 6 controls the red master batch, the yellow master batch and the blue master batch to be mixed according to a ratio of 5:4:1, and the Color-Eye spectrophotometry detects a rose No. 2 sample Color, and the control mechanism 6 controls the red master batch, the yellow master batch and the blue master batch to be mixed according to a ratio of 6:3:1. And other different color ratios are not described here.

When the third feeding mechanism 3 works, the three second discharging valves 22 are closed, the first discharging valve 15 and the third discharging valve 32 are opened, and the spinning main material and the cleaning agent are discharged according to a preset proportion.
When the screw rod is stopped for changing materials each time, the control mechanism 6 controls the three second discharging valves 22 and the three second metering pumps 23 to be closed, the first discharging valve 15, the first metering pump 16, the third discharging valve 32 and the third metering pump 33 are opened, the spinning main materials and the cleaning agent are discharged according to a preset proportion, and after the spinning main materials mixed with the cleaning agent pass through the screw rod, the pipeline, the dynamic mixer 45, the spinning box 7 and the fourth metering pump, the dye components in the spinning device are cleaned and taken away, so that the preparation is made for the next material with different colors. Through setting up control mechanism 6 and third feed mechanism 3, this spinning device can set for the procedure automatically and wash the pipeline, need not manual operation, convenient and fast.
In the present embodiment, the main component of the cleaning agent is a special resin material, and the cleaning agent is specially used for cleaning a plastic molding machine, and has high cleaning power and low residue. Its low residual properties benefit from its special molecular structure, making it very low in adhesion to metals, easily replaced by other resins, and thus reducing the residual properties. In addition, the cleaning agent is convenient to store and use, is safe and nontoxic, meets the environmental protection requirement, does not generate chemical reaction, has no corrosiveness and does not contain harmful substances. The cleaning agent mainly wets, permeates and swells degradation products, black spots, carbon deposition, color residues and other substances on the surface of the screw barrel by the action of the surfactant, thereby playing a role in cleaning. Sometimes, the combination of surfactant and grinding components (such as glass fiber, calcium carbonate and silicon dioxide) is adopted, and the pipeline is cleaned by utilizing the infiltration of the surfactant and the grinding action of inorganic filler.
The color master batch is a novel special colorant for high polymer materials and consists of three basic elements of pigment or dye, a carrier and an additive. The three-primary color masterbatch in the embodiment of the application is prepared from ACE dye, and the masterbatch has wide application in the field of plastic coloring and can improve the light resistance, weather resistance, electrical conductivity, antistatic effect and the like of plastics. Therefore, ACE dye has complete capability of being prepared into color master batches, and can meet the coloring requirements of different polymer products. In addition, ACE dye is a disperse dye, the molecular particle size of the dye is uniform, the speed is uniform and uniform during mixing diffusion, the color is not robbed, and the ACE dye is suitable for dyeing fabrics such as knitting, tatting polyester, polyester/cotton, polyester/wool, polyester/viscose and the like. Due to the requirements of the dyeing temperature and the dyeing time of the ACE dye and the stability of the ACE dye at high temperature, the ACE dye is very suitable for preparing color master batches. The three primary color master batch prepared by the ACE dye is selected, and the dispersion rate is consistent, the color is not robbed and the color is accurate during mixed coloring.
