DETAILED DESCRIPTION

[0014] like Figure 1 As shown:

[0015] A HDPE double-adjustable three-air outlet air ring, comprising an upper cover 1 and a lower cover 2, wherein the upper cover 1 and the lower cover 2 are fixedly connected by screws and a main air duct 4 is formed inside, the upper cover 1 is provided with a large nut 5, the large nut 5 is provided with a small nut 6, one end of the large nut 5 is connected to a wind core 7, one end of the small nut 6 is connected to an upper air lip 8, and one end of the lower cover 2 is provided with a lower air lip 12 and a bottom ring 13.

[0016] Specifically, after the upper cover 1 and the lower cover 2 are fastened, the gap between them becomes the main air duct 4 , and the main air duct 4 is connected to the air inlet 3 .

[0017] The large nut 5 is threadedly connected to the upper cover 1 , a first air hole 9 is provided on the large nut 5 , the small nut 6 is threadedly connected to the other end of the large nut 5 , and the upper air lip 8 and the air core 7 form a first air duct 10 .

[0018] The main air duct 4 is in communication with the first air hole 9 and the first air duct 10 , and the other end of the first air duct 10 is in communication with the outside.

[0019] The wind core 7 and the bottom ring 13 form a second wind duct 14. The wind core 7 is provided with a second wind hole 11. The first wind duct 10 is connected with the second wind hole 11 and the second wind duct 14. The other end of the second wind duct 14 is connected with the outside.

[0020] The bottom ring 13 is provided with a third air hole 15 , a third air duct 16 is formed between the bottom ring 13 and the lower air lip 12 , the second air duct is connected to the third air duct 16 through the third air hole 15 , and the other end of the third air duct 16 is connected to the outside.

[0021] The upper wind lip 8 is fixedly connected to the small nut 6 by screws, the wind core 7 is fixedly connected to the large nut 5 by screws, and the bottom ring 13 is fixedly connected to the lower cover 2 by screws.

[0022] Specifically, the utility model is an annular air outlet structure, that is, the upper cover 1, the lower cover 2, the air inlet 3, the large nut 5, the small nut 6, the wind core 7, the upper air lip 8, the lower air lip 12 and the bottom ring 13 are all annular structures.

[0023] Blowing principle; as shown by the arrow, air enters the air inlet 3, flows through the main air duct 4, and then blows to the outside through the 3-level secondary air duct; the first level is the first air hole and the first air duct, the second level is the second air hole and the second air duct, and the third level is the third air hole and the third air duct; among them, the first air hole and the first air duct can adjust the air volume, which can be adjusted by adjusting the depth of the threaded connection between the small nut and the large nut. When the threaded connection of the small nut is looser, that is, the small nut moves upward, the first air hole is less blocked by the small nut, the larger the air hole, the small nut moves upward, driving the upper air lip to move upward, the larger the first air duct is, and the larger the air output; conversely, when the small nut moves downward, the smaller the air output is;

[0024] Similarly, the air outlet size of the second air duct can be adjusted by moving the large nut and the air core up and down, and the third air duct follows.

[0025] The beneficial effects of the utility model are as follows: the utility model takes in air through the air inlet, flows through the main air duct, and then blows air to the inside through the three-level secondary air duct. The design of the three-level air duct makes the coverage of the blowing more uniform and the cooling of the film more uniform; the double nuts can adjust the air volume, can adapt to the cooling of films of different thicknesses, and is flexible in application; the design of the adjustable air volume air duct improves the cooling effect and increases the output.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
