[0022] In the utility model, the lower part of the wind chamber body 1 is connected to the wind chamber lower plate 3 through the separating ring 6, the wind chamber body 1 is provided with an air distribution port 18 connected with the wind cavity 4 above the separating ring 6, the inner side of the separating ring 6 is provided with an air guide plate 19 abutting against the lower part of the connecting plate 8 below, the inner side of the wind chamber lower plate 3 is provided with a lower wind plate 7, and the wind chamber body 1, the separating ring 6, the wind chamber lower plate 3 and the lower wind plate 7 are fixedly connected by bolts.

[0023] In the utility model, the inner side of the stroke chamber main body 1 is threadedly connected with a compressed air ring 9 through a connecting disk 8, and an adjusting handle 10 is provided at the connection between the compressed air ring 9 and the connecting disk 8. A wind protection ring 11 is provided on the top outer side of the compressed air ring 9. The cross section of the wind protection ring 11 is an L-shaped structure. The wind protection ring 11 is located on the vertical side of the L-shaped structure away from the edge of the compressed air ring 9, and a plurality of exhaust holes 21 are staggered in a ring array. The cross section of the compressed air ring 9 is a U-shaped structure. The two ends of the compressed air ring 9 are fixedly connected to the wind protection ring 11 and the adjusting handle 10 respectively. The height of the compressed air ring 9 on one side of the adjusting handle 10 is relatively low, and the lower part of the compressed air ring 9 on the side of the adjusting handle 10 is connected to the connecting disk 8 through a thread.

[0024] In the utility model, a wind cup 12 is arranged between the lower wind plate 7 and the air pressure ring 9, and the wind cup 12 is fixedly connected to the lower wind plate 7 by bolts. The top of the wind cup 12 is inclined to one side of the edge of the die cavity 5, and an outer air duct 13 connected to the die cavity 5 is formed between the air pressure ring 9 and the wind cup 12. An inner air duct 14 connected to the die cavity 5 is formed between the lower wind plate 7 and the wind cup 12. The air outlet of the air guide plate 19 is connected to the outer air duct 13. A plurality of air guide holes 20 connecting the outer air duct 13 and the inner air duct 14 are arranged on the inner side of the wind cup 12 below the air pressure ring 9. The inner air duct 14 is located at the outlet of the side close to the die cavity 5 as an air outlet 15 inclined to one side of the wind cup 12, and the wind cup 12 is provided with an air storage chamber 16 above the air outlet 15.

[0025] During the specific implementation of the utility model, the film blowing operation of the film bubble 22 is carried out through the die cavity 5, and the air is supplied through the air cavity 4 between the air chamber body 1 and the air chamber upper cover 2.

[0026] The air outlet 15 on one side of the inner air duct 14 blows air to the bottom of the film bubble 22 at the mold cavity 5, and as the film bubble 22 gradually increases from bottom to top, the wind from the air outlet 15 is blocked by the edge of the film bubble 22 and then rotates at the air storage cavity 16 outside the wind cup 12, thereby preliminarily cooling the bottom of the film bubble 22 and shaping and supporting the film bubble 22. At the same time, the wind blown out of the outer air duct 13 cools the top of the film bubble 22, gathers the wind direction through the wind protection ring 11, and discharges excess air to support and cool the film bubble 22.

[0027] During use, by rotating the adjustment handle 10, the outer side of the compressed air ring 9 moves up and down on the inner side of the connecting plate 8 through the thread, so that the air volume of the inner air duct 14 and the outer air duct 13 can be adjusted to adapt to the production of membrane bubbles 22 with different blowing ratios.

[0028] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
