[0023] See also Figures 1-7: In this embodiment, the nozzle assembly 1 further comprises an outer cooling assembly 2 and an inner cooling assembly 3. The outer cooling assembly 2 comprises an outer air duct outlet pipe 22 and an air inlet outer pipe 23. The air inlet outer pipe 23 and the outer air duct outlet pipe 22 are connected through a cooling roller 24. The two ends of the cooling roller 24 are rotatably connected with the air inlet outer pipe 23 and the outer air duct outlet pipe 22 respectively. A last-stage cooling arc air baffle 21 is fixed at the end of the outer air duct outlet pipe 22. The air outlet of the last-stage cooling arc air baffle 21 is communicated with the outer air duct outlet pipe 22. The liquid flowing out of the nozzle assembly 1 is located directly above the cooling roller 24. The inner cooling assembly 3 comprises an inner air duct outlet pipe 32 and an air inlet inner pipe 33. The air inlet inner pipe 33 is located inside the air inlet outer pipe 23 and forms a first passage sandwich. The inner air duct outlet pipe 32 is vertically penetrated from the curved end of the outer air duct outlet pipe 22. The outer air duct outlet pipe 22 and the inner air duct outlet pipe 32 form a third passage sandwich. The outer air duct outlet pipe 22 is rotatably connected with the inner air duct outlet pipe 32. The inner air duct outlet pipe 32 and the air inlet inner pipe 33 are communicated through a profiled inner cover 34. The profiled inner cover 34 and the cooling roller 24 form a second passage sandwich. The above-mentioned three passage sandwiches are communicated with the outer air duct outlet pipe 22. The end of the inner air duct outlet pipe 32 is fixedly connected with a middle-stage separation cooling arc air baffle 31. The middle-stage separation cooling arc air baffle 31 is located below the profiled inner cover 34. The air outlet of the middle-stage separation cooling arc air baffle 31 is communicated with the air inlet inner pipe 33.

[0024] In this embodiment, the melting module melts the material and then delivers it to the nozzle assembly 1. The liquid material is linearly sprayed on the surface of the cooling roller 24 through the nozzle assembly 1. The air inlet cooling module blows in cooling gas, such as air cooled by a refrigeration mechanism. Please refer to Figure 6 Since the pipe axes of the air inlet outer pipe 23 and the air inlet inner pipe 33 are collinear, when the high-speed cooling gas passes through the air inlet outer pipe 23, the gas flows through the first passage sandwich and the inside of the air inlet inner pipe 33. The gas located in the first passage sandwich quickly passes through the second passage sandwich between the cooling roller 24 and the profiled inner cover 34. After the gas passes through the inner wall bottom surface of the cooling circumferential surface 241 and the outer wall surface of the profiled inner cover 34 for rapid heat exchange, the gas is discharged to the outer air duct outlet pipe 22 through the third passage sandwich and then acts on the last-stage cooling arc air baffle 21 through the outer air duct outlet pipe 22. The nozzles on the surface of the last-stage cooling arc air baffle 21 are affected by the gas from the outer air duct outlet pipe 22 and spray the gas on the surface of the cooling circumferential surface 241. The outer wall of the cooling circumferential surface 241 is cooled. The cooled part quickly rotates to the position in contact with the liquid, ensuring that the temperature of the cooling circumferential surface 241 located in the liquid contact part is minimized, thereby ensuring the cooling effect of the belt body.

Please refer toFigure 7 The spray head of the middle separation cooling arc air baffle 31 sprays gas obliquely upward against the rotation direction of the cooling roller 24 in the tangent direction of the cooling roller 24, a part of the gas acts on the surface of the cooling circumferential surface 241, is affected by the arc-shaped guide of the middle separation cooling arc air baffle 31, and the wind blows to the belt body, promotes the separation of the belt body and the cooling circumferential surface 241, and simultaneously cools the cooling circumferential surface 241.

[0027] In this embodiment, the middle part of the cooling roller 24 is provided with a cooling circumferential surface 241, the cooling circumferential surface 241 is connected and transitioned with the pipe opening of the cooling roller 24 through a continuous tangent arc surface, and the pipe opening diameter of the cooling roller 24 is smaller than the diameter of the cooling circumferential surface 241.

[0028] In this embodiment: firstly, the cooling roller 24 is disc-shaped, and the air inlet end can only be located at the center, therefore, in order to reduce wind energy loss, tangent arc surfaces are arranged at both ends of the cooling roller 24 to transition with the cooling circumferential surface 241, the cooling roller 24 and the imitation inner cover 34 are arranged in cooperation to form a wind flow channel therebetween, and the tangent surfaces can reduce wind energy loss, so that the cooling gas can move along the second channel interlayer, thereby ensuring that the wind adheres to the cooling circumferential surface 241 to exchange heat, and ensuring the heat exchange efficiency of the inner wall of the cooling circumferential surface 241.

[0029] In this embodiment: the lower part of the outer cooling assembly 2 and the inner cooling assembly 3 is provided with a support, the support is rotationally connected to both ends of the cooling roller 24 through a rotating bearing, gears are arranged at both ends of the cooling roller 24, and a driving machine box is arranged below the support, the driving machine box extends to the gears of the cooling roller 24 through a driving assembly 4 to drive the rotation connection of the cooling roller 24.

[0030] In this embodiment: the support supports the cooling roller 24, the driving assembly 4 adopts a belt drive, the belt is connected with the gear, a transmission box connected with a driving motor is arranged below, so that the belt drives the high-speed rotation of the cooling roller 24, and the cooling roller 24 is rotationally connected with the air inlet outer pipe 23 and the outer air duct outlet pipe 22 through a dynamic sealing structure, thereby ensuring the air tightness.

[0031] In the embodiment, the support is fixedly connected with a locking plate 5, the locking plate 5 is provided with two track grooves, the outer air duct outlet pipe 22 is fixedly connected with an outer adjusting rod 25, the inner air duct outlet pipe 32 is fixedly connected with an inner adjusting rod 35, the outer adjusting rod 25 and the inner adjusting rod 35 rotate in the track grooves of the locking plate 5 and are locked with the locking plate 5 through a fixer.

The outer adjusting rod 25 and the inner adjusting rod 35 are fixedly connected with the outer air duct outlet pipe 22 and the inner air duct outlet pipe 32 respectively, and the locking plate 5 is fixed with the support, so that the outer adjusting rod 25 and the inner adjusting rod 35 can rotate in the track grooves and are locked with the locking plate 5 through the locking mechanism of the hand screw and the nut on the top of the outer adjusting rod 25 and the inner adjusting rod 35.
