[0039] The air pump 7 is installed on the blunt cone block 6 and is located on one side of the blunt cone block 6 near the entrance of the inclined hole 61. A through hole 63 is opened in the center of the blunt cone block 6. The through hole 63 is connected to the air outlet of the air pump 7. The air pump 7 and the spray gun 2 are electrically connected;

[0040] The mixing mechanism 8 is installed on the side opposite to the blunt cone block 6 and the air pump 7, and is connected to the spray gun 2. The mixing mechanism 8 cooperates with the air pump 7 to mix the black material, the white material, the carbon-based flame retardant, and the graphene composite inorganic flame retardant, and sprays the mixed mixture through the spray gun 2.

The frame 84 is located on the side away from the blunt cone block 6. The difference between the first support frame 82 is that triangular plates 86 are arranged on the arcs at both ends of the second support frame 84. The other parts have the same structure. The triangular plates 86 are arc surfaces. The first support frame 82 and the second support frame 84 are arranged perpendicular to each other. The middle part of the second support frame 84 is connected to the other end of the cylinder 83. The cylinder 83 is sleeved with a turbine 85. The mixing mechanism 8 also includes a limiting mechanism 80 installed in the closed cylinder 81, and the limiting mechanism 80 limits the first support frame 82 and its connecting parts.

[0042] A conical head 831 is fixed to one end of the cylinder 83 close to the blunt cone block 6 , and the axis of the conical head 831 is in the same straight line as the axis of the blunt cone block 6 .

[0043] The conical head 831 can disperse the mixture and the airflow generated by the air pump 7 to ensure that the mixture passes through the turbine 85 and is stirred by the turbine 85 .

[0044] The limiting mechanism 80 includes a wedge block 801 relatively fixed inside the sealed tube 81. The wedge block 801 is arc-shaped, and one side is in contact with both ends of the second support frame 84. It also includes a limiting frame 802 fixed on the inner wall of the sealed tube 81. There are two limiting frames 802, which are arranged between the first support frame 82 and the blunt cone block 6, and are staggered with the two sides of the first support frame 82.

[0045] A cleaning mechanism 9 is installed in the sealed cylinder 81, and the cleaning mechanism 9 cleans the mixture retained in the sealed cylinder 81 and the pipeline from the sealed cylinder 81 to the spray gun 2. The cleaning mechanism 9 includes an unsealing part 90 and a cleaning part 91. The unsealing part 90 includes a second hole 901 that is relatively opened on the sealed cylinder 81. The second hole 901 and the second support frame 84 are in the same plane. A pressing plate 902 is installed through the second hole 901, and an elastic sheet 903 is installed between the pressing plate 902 and the outer wall of the sealed cylinder 81.

[0046] The cleaning part 91 includes an air tank 911 installed in the cylinder 83, the air tank 911 is connected to a micro air compressor 912, an air bag 913 is installed on the micro air compressor 912, the air tank 911 and the air bag 913 are connected by a pipeline, and an electric control valve 914 is provided at the connection between the pipeline and the air tank 911, and the micro air compressor 912 and the electric control valve 914 are electrically connected.

[0047] A guide plate 10 is disposed opposite to the sealed tube 81 . The guide plate 10 is triangular and has an arc surface, and fits with the inner wall of the sealed tube 81 .

[0048] The air pump 7 accelerates the mixture to the spray gun 2 and sprays it out from the spray gun 2. However, after stopping use, a small amount of the mixture will still adhere to the inner wall of the sealed cylinder 81 and the pipeline. When it is necessary to clean the mixture adhered to the inner wall of the sealed cylinder 81 and the pipeline from the sealed cylinder 81 to the spray gun 2, the electric control valve 914 on the air tank 911 is opened, and the compressed air in the air tank 911 enters the airbag 913, and the airbag 913 expands and adheres to the inner wall of the sealed cylinder 81. The airtight tube 81 is sealed by the air bag 913. Then the staff squeezes the pressing plate 902 with their fingers, and the pressing plate 902 presses the two ends of the second support frame 84. The squeezed second support frame 84 is separated from the wedge block 801. At this time, the air pump 7 is turned on. Since the air bag 913 seals the sealed tube 81, the expanded air bag 913 acts like a piston. As the air pump 7 continuously injects the outside air into the sealed tube 81, the air bag 913 and its connecting parts are in the sealed tube. 81, and then enters the pipeline leading to the spray gun 2, cleans the inner wall of the sealed cylinder 81 and the pipeline, and when it reaches the vicinity of the spray gun 2, it cannot move forward because the diameter of the inlet of the spray gun 2 is smaller. At this time, the micro air compressor 912 is started to pump the gas in the air bag 913 back into the gas storage tank 911. At this time, under the high-pressure airflow generated by the air pump 7, the gathered mixture is discharged from the spray gun 2, and then the electric control valve 914 is opened to drive the air bag 913 to expand again, and the reverse Turn on the air pump 7 to extract the air in the sealed tube 81, driving the airbag 913 and its connecting parts to reset. During this process, the first support frame 82 is guided by the guide plate 10 in the sealed tube 81. After the arc-shaped hypotenuse of the triangular plate 86 and the guide plate 10 come into contact, the second support frame 84 can be driven to return to its original position smoothly, ensuring that the wedge block 801 can re-limit the second support frame 84. Then, turn on the micro air compressor 912 again to drive the airbag 913 to reset and complete the cleaning work.

[0049] The sealed tube 81 is connected to an inclined tube 11 . The connection between the inclined tube 11 and the sealed tube 81 is located between the first support frame 82 and the blunt cone block 6 . A one-way valve 12 is arranged in the inclined tube 11 .

[0050] When the device is subsequently maintained, the high-pressure water gun can be directly connected to the inclined tube 11. After the water flows through the one-way valve 12, the high-speed water flow flushes the turbine 85 and the inside of the closed cylinder 81, and then is sprayed out from the spray gun 2 through the pipeline. During this period, the pipeline is flushed. This process can be used synchronously with the air pump 7 to further accelerate the flow rate of the water flow and enhance the cleaning effect.

[0051] The nozzle of the spray gun 2 is flat. Since a plate-shaped product is to be produced and the mold is a rectangular parallelepiped, the flat nozzle can spray the mixture into the mold more evenly than a traditional round nozzle.

[0052] The electric-controlled flow valve 62 is arranged on the corresponding pipeline and close to one side of the blunt cone block 6. When the electric-controlled flow valve 62 is closed, the amount of mixing of the three materials is reduced to avoid a large amount of waste of materials.

[0053] Working principle: the staff aims the nozzle of the spray gun 2 at the mold, then turns on the switch on the spray gun 2, and the high-pressure foaming machine 1 and the electronically controlled flow valve 62 electrically connected to the spray gun 2 are turned on synchronously. Under the action of compressed nitrogen, the carbon-based flame retardant and graphene composite inorganic flame retardant in the first storage tank 3 and the second storage tank 4 enter the inclined hole 61 in the blunt cone block 6 in a certain proportion from the corresponding supply pipe 5 and the connected pipe through the siphon principle. The high-pressure foaming machine 1 simultaneously transports a certain proportion of black material and white material to an inclined hole 61 in the blunt cone block 6, and violently collides at the intersection of the inclined holes 61 to generate vortices. Then the high-speed flowing mixture is mixed twice through the turbine 85, and enters the spray gun 2 part through the pipe connected to the spray gun 2 through the closed cylinder 81, and is sprayed from the nozzle of the spray gun 2 into the mold.
