[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] For color pastes with higher viscosity, this utility model first adds them to the first stirring mixer and heats them using an electric heating assembly. The second discharge regulating valve and the color paste dripping regulating valve are then used to adjust the ratio of the color pastes in the mixing kettle and the first stirring mixer. The mixture is then filled into the barrel through the second filling line. This solves the problem of uneven mixing of color pastes with higher viscosity and allows for flexible mixing of color pastes of varying proportions. For color pastes with higher viscosity, this utility model heats them with an electric heating assembly before mixing them, rather than directly mixing them with other color pastes. This results in more uniform mixing of the color pastes and significantly improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1 As shown, this embodiment provides a color paste mixing device, including a mixing kettle 1, a first discharge regulating valve 2, a discharge pump 3, a discharge ball valve 4, a second discharge regulating valve 5, a first stirring mixer 6, a color paste dripping regulating valve 7, a second stirring mixer 8, a first filling pipeline 13, a second filling pipeline 14, a barrel, and a weighing device 11. The bottom of the mixing kettle 1 is connected to the inlet of the first discharge regulating valve 2, the outlet of the first discharge regulating valve 2 is connected to the inlet of the discharge pump 3, and the outlet of the discharge pump 3 is connected to the discharge ball valve 4, the first filling pipeline 13, and the second filling pipeline 14. The inlet of the first filling line 13 is connected, the outlet of the discharge ball valve 4 is connected to the inlet of the second discharge regulating valve 5, the outlet of the first stirring mixer 6 is connected to the inlet of the color paste dripping regulating valve 7, the outlet of the color paste dripping regulating valve 7 and the outlet of the second discharge regulating valve 5 are connected to the inlet of the second stirring mixer 8, the outlet of the second stirring mixer 8 is connected to the inlet of the second filling line 14, the outlets of the first filling line 13 and the second filling line 14 are arranged above the barrel, and the weighing device 11 is arranged at the bottom of the barrel.

[0020] In this embodiment, the outer surface of the first stirring mixer 6 is wrapped with an electric heating assembly. The temperature of the electric heating assembly is 20-70°C. In this embodiment, 20°C, 50°C, or 70°C can be selected based on actual conditions. A temperature sensor is installed on the inner wall of the first stirring mixer 6. The volume of the second stirring mixer 8 ranges from 20 to 200 L. In this embodiment, 20 L, 100 L, or 200 L can be selected based on actual conditions. A purge line 12 is also provided. The outlet of the purge line 12 is connected to the inlet of the second discharge regulating valve 5. After mixing is completed, the material is purged through the purge line. The volume range of the mixing kettle 1 is 500~20000L. In this embodiment, 500 L, 5000L and 20000L can be selected according to actual conditions. The diameter range of the second discharge regulating valve 5 is DN15~80. In this embodiment, DN15, DN60 and DN80 can be selected according to actual conditions. The diameter range of the color paste dripping regulating valve 7 is DN15~50. In this embodiment, DN15, DN25 and DN50 can be selected according to actual conditions.

[0021] In this embodiment, an interlocking unit and a computer control terminal are also provided. Flowmeters are installed on the pipeline between the color paste addition control valve and the second stirring mixer, and on the second filling pipeline. The computer control terminal monitors the temperature sensor, flowmeter, and weighing device, thereby controlling the temperature of the electric heating assembly through the interlocking unit. When the temperature of the flowmeter and temperature sensor on the pipeline between the color paste addition control valve and the second stirring mixer, and on the second filling pipeline, falls below a set value, the color paste addition control valve is increased, raising the temperature of the electric heating assembly. When the flowmeter and temperature sensor on the pipeline between the color paste addition control valve and the second stirring mixer, and on the second filling pipeline, falls below a set value and the temperature sensor is at the set value, the color paste addition control valve is increased, thereby ensuring that the color paste with a higher viscosity is added according to the set ratio.

[0022] The working principle of this embodiment is further described below:

[0023] In this embodiment, low-viscosity color paste is added to the mixing kettle. After the discharge pump is activated, the flow rate is adjusted via the first regulating valve. For higher-viscosity color paste, it is first added to the first stirring mixer and heated using an electric heating assembly. The ratio of the color paste in the mixing kettle and the first stirring mixer is then adjusted using the second discharge regulating valve and the color paste dripping regulating valve. The mixture is then filled into the barrel via the second filling line. This solves the problem of uneven mixing of high-viscosity color paste and allows for flexible formulation of various color paste ratios. If color paste mixing is not required, the material pumped from the discharge pump can simply be poured into the barrel via the first filling line. In this embodiment, high-viscosity color paste is not directly mixed with other color pastes. Instead, it is heated via the electric heating assembly before mixing, resulting in more uniform mixing and significantly improving production efficiency.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
