[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-4 An embodiment of this utility model provides an environmentally friendly printer toner processing mixing extruder, comprising a base 1, a mixing cylinder 8 at the upper end of the base 1, a drive device 3 at the rear end of the mixing cylinder 8, a feeding mechanism 2 at the rear end of the outside of the mixing cylinder 8, a mixing cylinder 4 at the upper end of the feeding mechanism 2, weighing mechanisms 5 on both sides of the upper end of the mixing cylinder 4, a guiding mechanism 6 above the weighing mechanism 5, a raw material cylinder 7 on one side above the guiding mechanism 6, a pelletizing mechanism 9 at the front end of the mixing cylinder 8, a discharge mechanism 10 below the pelletizing mechanism 9, a cooling water tank 14 at the front end inside the base 1, and the cooling water tank 14 is connected to the discharge mechanism 10, and a medium cooling device 25 is provided at the middle position inside the base 1, the medium cooling device 25 includes an evaporator 26, and the evaporator 26 is located below the cooling water tank 14.

[0023] Please see Figure 1 , Figure 2 and Figure 3 Weighing mechanism 5 has a weighing cylinder 16 installed inside, and the weighing cylinder 16 is slidably connected to the weighing mechanism 5. A weighing sensor 17 is installed at the connection between the weighing cylinder 16 and the weighing mechanism 5. A feeding pipe 18 is installed at the lower end of the weighing cylinder 16, and an electric control valve is provided outside the feeding pipe 18. The upper end of the weighing cylinder 16 is connected to the discharge port of the guiding mechanism 6 through a corrugated hose. A guiding motor 20 is installed at one end of the guiding mechanism 6. An auger 19 is rotatably installed inside the guiding mechanism 6, and the output shaft of the guiding motor 20 is fixed to the auger 19. The output end of the weighing sensor 17 is connected to the processor, and the output end of the processor is connected to the guiding motor 20 and the electric control valve.

[0024] The toner raw material enters the feeding mechanism 6 through the raw material cylinder 7. The output shaft of the feeding motor 20 drives the auger 19 to rotate, which on the one hand transports the raw material to the weighing mechanism 5, and on the other hand realizes the start and stop of the raw material movement position. Under the conveying of the auger 19, the raw material enters the weighing cylinder 16 from the corrugated hose at the lower end of the feeding mechanism 6. By setting a weighing sensor 17 at the connection between the weighing cylinder 16 and the weighing mechanism 5, the mass of the raw material in the weighing cylinder 16 can be accurately determined. When the set weight is reached, the feeding motor 20 is turned off and the electric control valve outside the feed pipe 18 is opened, allowing the raw material to enter the mixing cylinder 4 for premixing.

[0025] Please see Figure 2 A spiral heat exchange tube 13 is provided in the inner wall of the front end of the mixing drum 8. A cooling water inlet pipe 11 is provided at one end of the spiral heat exchange tube 13. A circulation pump 15 is provided at the rear end of the cooling water tank 14 and is connected to the cooling water inlet pipe 11. A cooling water outlet pipe 12 is provided at the other end of the spiral heat exchange tube 13 and extends into the interior of the pelletizing mechanism 9. A cooling water spray pipe 23 is installed at one end of the cooling water outlet pipe 12 inside the pelletizing mechanism 9. By turning on the circulation pump 15, the cooling water inside the cooling water tank 14 is transported to the spiral heat exchange tube 13 in the inner wall of the mixing drum 8 through the cooling water inlet pipe 11. The heat exchange forms a cooling effect on the material inside the mixing drum 8.

[0026] Please see Figure 4 The mixing cylinder 8 has multiple annularly distributed extrusion holes 21 inside its front end. A cutter 22 is installed on the outside of the extrusion holes 21, and the shaft of the cutter 22 is connected to the shaft of the mixing extrusion screw inside the mixing cylinder 8. The cooling water spray pipe 23 is located above the outside of the extrusion holes 21. When the cooled material is discharged from the extrusion holes 21, the cutter 22 cuts the extruded material to keep it in a granular state. During the granulation process, the cooling water from the spiral heat exchange tube 13 enters the cooling water spray pipe 23 from the cooling water outlet pipe 12. The water is sprayed onto the outside of the cut carbon powder particles through the cooling water spray pipe 23 to further cool the carbon powder particles and prevent them from sticking together.

[0027] Please see Figure 2 and Figure 4 The discharge mechanism 10 has a discharge plate 24 fixedly installed inside. The discharge plate 24 has an inclined structure and several through holes inside. Because the discharge plate 24 has an inclined structure and several micro holes inside, carbon powder particles can be discharged outside the discharge mechanism through the discharge plate 24, and cooling water can flow back to the cooling water tank through the micro holes to continue cooling.
