[0025] Embodiment 2: Based on embodiment 1, further improvement is made in that Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig. 9As shown, a plurality of raw material barrels 7 are arranged on the upper side of the mixing barrel 1. In this embodiment, four raw material barrels 7 are arranged, and the specific number can be flexibly selected according to the process. Flame retardant powder of polyurethane aluminum alloy composite insulation profile raw material is stored in the raw material barrel 7. Since a plurality of raw material barrels 7 are arranged, catalysts, chain extenders and stabilizers can be stored in the remaining raw material barrels 7. A feed pipe 16 fixedly connected to the mixing barrel 1 is fixedly connected to one side of the raw material barrel 7. An observation window 20 is arranged on one side of the raw material barrel 7.

In a natural state, the lower end of the ball 904 is lower than the height when the rotating rod 501 moves to the top, so that when the rotating rod 501 slides from the top, it pushes the ball 904 to rise. A sealing plate 903 which is sealed with the discharge pipe 16 is fixedly arranged on the slide bar 901. A disturbing rod 902 which is located on the inner side of the raw material barrel 7 is fixedly arranged on the slide bar 901. A reset mechanism 10 is arranged on the upper end of the slide bar 901. The reset mechanism 10 includes a fixed arrangement The reset cylinder 1001 on the upper side of the raw material cylinder 7 has a reset spring 1002 fixedly arranged on the inner side of the reset cylinder 1001, and the lower end of the reset spring 1002 is fixedly arranged with a slide plate 1003 slidably connected to the inner side of the reset cylinder 1001. The upper end of the slide bar 901 slides through the raw material cylinder 7 and extends to the inner side of the reset cylinder 1001 and is fixedly connected to the lower end of the slide plate 1003. When in use, when the rotating plate 2 drives the rotating rod 501 to rotate to the vicinity of the top end, the rotating rod 501 will squeeze the ball 904, drive the slide bar 901 at the upper end of the ball 904 to slide upward, and then drive the slide plate 1003 at the top end of the slide bar 901 to slide upward on the inner side of the reset cylinder 1001, thereby compressing the reset spring 1002, and When the sealing plate 903 on the slide bar 901 slides out from the inner side of the discharge tube 16, the discharge tube 16 can be opened, so that the flame retardant powder, catalyst powder, chain extender powder and stabilizer powder on the inner side of the raw material barrel 7 fall into the interior of the mixing barrel 1 through the discharge tube 16, completing the automatic discharge process. When the rotating rod 501 is separated from the ball 904, the return spring 1002 will push the slide plate 1003 to slide down, thereby driving the slide bar 901 to slide down, so that the sealing plate 903 on the slide bar 901 slides back into the inner side of the discharge tube 16, so that the discharge tube 16 is blocked, thereby realizing the intermittent discharge of the flame retardant powder, catalyst powder, chain extender powder and stabilizer powder, and improving the raw material mixing effect.

[0026] It should be noted that, when using the raw material mixing device for the production of polyurethane aluminum alloy composite thermal insulation profiles, the flame retardant powder, catalyst powder, chain extender powder and stabilizer powder of the raw materials are first poured into the interior of the raw material barrel 7 through the first feeding pipe 8, and the polyurethane particles are poured into the interior of the inner barrel 3 through the second feeding pipe 18. Then, the servo motor 1206 drives the rotating shaft 1201 to rotate, and then drives the first gear 2101 on the rotating shaft 1201 to rotate, so that the first gear 2101 is meshed with the second gear 2102, driving the second gear 2102 to rotate in the opposite direction, and the second gear 2102 drives the outer connecting gear ring 2103 to rotate in the same direction, which can drive the rotating plate 2 on one side of the connecting gear ring 2103 and the rotating shaft 1201 rotates simultaneously, and makes the rotating plate 2 rotate in the opposite direction to the rotating shaft 1201, thereby making the three rows of second crushing rods 1202 on the rotating shaft 1201 and the three rows of first crushing rods 1101 inside the rotating shaft 1201 rotate in the opposite direction, and pass through the gap between the two adjacent crushing rods of each other, so that the two adjacent rows of second crushing rods 1202 and the first crushing rods 1101 form a shear force with each other, so that the polyurethane particles between the second crushing rods 1202 and the first crushing rods 1101 are crushed. During the crushing process, when the rotating plate 2 drives the rotating rod 501 to rotate to the vicinity of the top end, the rotating rod 501 squeezes the ball 904, drives the sliding rod 901 at the upper end of the ball 904 to slide upward, thereby driving the slide plate at the top of the slide rod 901 1003 slides upward on the inner side of the reset cylinder 1001, thereby compressing the reset spring 1002, and at the same time causing the sealing plate 903 on the slide bar 901 to slide out from the inner side of the discharge tube 16, so that the discharge tube 16 can be opened, so that the flame retardant powder, catalyst powder, chain extender powder and stabilizer powder inside the raw material cylinder 7 fall into the interior of the mixing cylinder 1 through the discharge tube 16, completing the automatic discharge process; when the rotating rod 501 is separated from the ball bearing 904, the reset spring 1002 will push the slide plate 1003 to slide down, thereby driving the slide bar 901 to slide down, so that the sealing plate 903 on the slide bar 901 slides back into the inner side of the discharge tube 16, so that the discharge tube 16 is blocked, and the flame retardant powder, catalyst powder, chain extender powder and stabilizer powder are released. The intermittent feeding of fixed-dose powder, the rotating plate 2 will drive the rotating rod 501 to rotate together during the rotation process. When the rotating rod 501 rotates, the self-rotating gear 504 at one end of the rotating rod 501 is meshed with the fixed gear ring 505 on the edge of the mixing barrel 1, so that the self-rotating gear 504 rotates, which can drive the rotating rod 501 to rotate while revolving, so that the several stirring rods 503 at one end of the rotating rod 501 can rotate while revolving inside the mixing chamber 22, so that the flame retardant powder, catalyst powder, chain extender powder and stabilizer powder inside the mixing chamber 22 are mixed, and when the particles of the crushed polyurethane particles inside the inner barrel 3 are smaller than the diameter of the through hole 4, the polyurethane particles will enter the interior of the mixing chamber 22 through the through hole 4.The polyurethane particles are mixed with the flame retardant powder, the catalyst powder, the chain extender powder and the stabilizer powder. Since the inner cylinder 3 is in the process of rotating during the mixing process, the mixing effect of the polyurethane particles with the flame retardant powder, the catalyst powder, the chain extender powder and the stabilizer powder is further improved. After the mixing is completed, the liquid raw material is poured into the interior of the mixing cylinder 1 through the liquid inlet pipe 23. In the process of mixing the liquid raw materials, all the raw materials can be mixed through the internal stirring component 5 to make the reaction more uniform and improve the reaction efficiency. Finally, the electric telescopic rod 1903 drives the sealing plate 1902 to slide out of the inner side of the discharge trough 1901, so that the discharge trough 1901 can be connected with the discharge port 6, so that the mixed raw materials in the mixing chamber 22 can be discharged. In the process of discharging the raw materials, the inside of the mixing cylinder 1 can also be stirred to improve the feeding efficiency.
