[0017] The present invention is further described in detail below in conjunction with specific implementation methods.

[0018] Color mixing device such as Figure 1 As shown, it includes a mixing barrel 1 and a pre-mixing device 9 installed above the mixing barrel 1. The pre-mixing device 9 includes a proportioning hopper 91 for placing different colorants for proportioning and a mixer housing 93 for preliminarily mixing the colorants. The proportioning hopper 91 supplies the colorants to the mixer housing 93, and the mixer housing 93 preliminarily mixes the colorants to make the colorants preliminarily dispersed, and then discharges the colorants to the mixing barrel 1. The mixing barrel 1 is as shown in FIG. Figure 2As shown, a stirring blade 15 is provided therein, and the stirring blade 15 fully stirs the colorant so that the colorant is fully mixed and evenly colored. The mixed colorant is discharged through the discharge port 6 at the bottom of the stirring barrel 1.

[0019] The premixing device 9 has two proportioning hoppers 91, each for simultaneously placing two different materials. The proportioning hopper 91 discharges materials to the mixer housing 93 through the proportioning outlet 92 at the bottom thereof, and the mixer housing 93 discharges materials to the mixing barrel 1 through the discharge port at the bottom thereof. A feed hopper 10 is installed above the mixing barrel 1, and a storage box 101 is provided below the feed hopper 10. The discharge port of the feed hopper 10 discharges materials to the storage box 101, and the discharge port of the storage box 101 discharges materials to the mixing barrel 1.

[0020] The color material mixing operation process is as follows: the mixing barrel 1 is provided with a first feeding pipe 2 and a second feeding pipe 3, the discharge port of the mixer housing 93 is connected to the first feeding pipe 2, and the discharge port of the storage box 101 is connected to the second feeding pipe 3. First, the plastic raw material is divided into two parts, one of which is plastic raw material and color material entering the mixer housing 93 through the proportioning hopper 91, and the mixer housing 93 performs preliminary mixing on the color material to make the color material preliminarily dispersed, and the color material after preliminary mixing enters the mixing barrel 1 through the first feeding pipe 2, and the other plastic raw material is stored in the storage box 101 through the feeding hopper 10, and then enters the mixing barrel 1 from the second feeding pipe 3 through the storage box 101. The color material after preliminary mixing and the remaining plastic raw material are stirred in the mixing barrel 1 by the stirring blade 15 driven by the motor 5. The stirring blade 15 includes an upper plate portion 151 with an upward folded edge and a lower plate portion 152 with a downward folded edge. The upper plate portion 151 and the lower plate portion 152 face opposite directions. When the stirring blade 15 rotates, the upper plate portion 151 and the lower plate portion 152 respectively generate stirring forces in the same direction to both sides, which can drive the colorant in the stirring barrel 1 to rotate and promote the colorant to be fully mixed. Both the mixer housing 93 and the stirring barrel 1 are closed devices to prevent the colorant from being disturbed by external substances during the initial mixing and full mixing process, and have a good anti-fouling effect.

[0021] like Figure 2As shown, a filling cavity 14 is provided on the inner wall of the mixing barrel 1, and the filling cavity 14 is filled with a replaceable filling liquid. The filling cavity 14 is provided with a liquid inlet 7 at the top of the side of the mixing barrel 1, and a liquid outlet 8 is provided at the bottom of the side opposite to the liquid inlet 7 of the mixing barrel 1. A heat insulating layer 11 is installed on the outer wall of the mixing barrel 1, and a heating layer 12 is installed on the inner side of the heat insulating layer 11. A heating tube 13 is installed inside the heating layer 12, and the heating tube 13 heats the filling liquid to adjust the temperature of the filling liquid. A temperature sensor 16 is installed in the mixing barrel 1, and a display screen 17 electrically connected to the temperature sensor is installed on the outer wall of the mixing barrel 1. The stirring blade 15 stirs continuously, generates heat by friction with the colorant, and the temperature sensor 16 senses the temperature, and the temperature signal is sent to the display screen 17 for display. When the operator sees that the display screen 17 shows that the temperature in the mixing barrel 1 is too high, the operator promptly replaces the filling liquid in the filling chamber 14. Specifically, the liquid outlet 8 is first opened to discharge the hot filling liquid, and then the liquid outlet 8 is closed. Then, the cold filling liquid input pipe is connected to the liquid inlet 7, and the water pump is started to inject the cold filling liquid into the filling chamber 14 through the liquid inlet 7 to reduce the temperature in the mixing barrel 1, avoid the excessive temperature in the mixing barrel 1 affecting the coloring power of the colorant, and improve the product quality.

[0022] The first feed pipe 2, the second feed pipe 3 and the discharge port 6 of the mixing barrel 1 are all provided with valves.

[0023] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
