The air ring is generally divided into single air outlet air ring, double air outlet air ring, etc. according to different structures and functions.

[0003] However, the air volume adjustment of such film blowing air rings in the prior art is relatively inconvenient. Generally, the air volume can only be adjusted as a whole by setting the width gap of the air outlet, and cannot be adjusted locally as needed. Therefore, this problem requires a semi-automatic local adjustment film blowing air ring to improve it. Utility Model Content

Wind slots 6, adjusting screws 7, upper air outlet wind wall 8, lower air outlet wind wall 9, upper air outlet 10, and lower air outlet 11. Several raised blocks 5 are evenly and fixedly arranged inside the air ring shell 1, and air outlet slots 6 are arranged between the raised blocks 5. Several adjusting screws 7 are arranged on the outer surface of the upper end of the air ring shell 1 through threaded engagement. An upper air outlet wind wall 8 is arranged at the upper end of the air ring shell 1, and a lower air outlet wind wall 9 is arranged at the lower end of the upper air outlet wind wall 8. An upper air outlet 10 is arranged between the upper air outlet wind wall 8 and the air ring shell 1, and a lower air outlet 11 is arranged between the lower air outlet wind wall 9 and the air ring shell 1.

[0022] The upper air outlet wind wall 8 is annular and is arranged inside the air ring housing 1 by means of a threaded movably screwed connection, so that the upper air outlet wind wall 8 can be adjusted in up and down position by means of the threaded connection, thereby adjusting the overall gap of the upper air outlet 10, so as to adjust the air volume and air pressure of the upper air outlet 10 as a whole;

[0023] The lower air outlet wind wall 9 is annular and is screwed together at the lower end of the air ring housing 1 through a threaded connection. The upper and lower positions of the lower air outlet wind wall 9 can be adjusted through the threaded connection, thereby adjusting the overall gap of the lower air outlet 11, thereby adjusting the air volume and air pressure of the lower air outlet 11 as a whole.

[0024] The upper air outlet 10 has an angle of 20 degrees; 20 degrees is a reasonable cooling blowing angle to achieve better cooling effect of the film bubble; and forms the best inflation curve with the film;

[0025] A membrane bubble body 12 is disposed in the middle of the inner side of the air ring housing 1;

[0026] The lower end of the adjusting screw 7 is arranged between the air outlet slots 6 formed by a plurality of raised blocks 5, so that when the adjusting screw 7 is screwed in and adjusted, the adjusting screw 7 can be moved up when it is rotated counterclockwise, thereby increasing the gap of the air outlet slots 6, and the air outlet volume becomes larger, and the corresponding film bubble becomes thicker; conversely, when the adjusting screw 7 is moved downward, the air outlet volume will become larger or smaller, thereby making the film bubble thinner.

[0027] Working principle: When using the device, multiple air inlet ducts 2 take in air from multiple points inside the air ring housing 1, and then the air flow rotates inside the air ring housing 1 and contacts the air inlet wind wall 3. At this time, the air inlet wind wall 3 acts as a flow barrier, so that the high-speed air flow entering from the air inlet duct 2 is split during rotation and can enter the air inlet honeycomb hole 4; then the air flow enters the air inlet honeycomb hole 4 to increase the cooling wind pressure; then it flows through the air outlet slot 6 formed between the multiple raised blocks 5, and then blows out through the upper air outlet wind wall 8 and the lower air outlet wind wall 9, and the air outlet operation is completed;

[0028] At this time, when the adjusting screw 7 is screwed in the thread, the adjusting screw 7 can be moved up when it is rotated counterclockwise, so that the gap of the air outlet slot 6 can be increased, and the air outlet volume becomes larger, and the corresponding film bubble here becomes thicker; conversely, when the adjusting screw 7 is moved down, the air outlet volume can be increased or decreased, so that the film bubble can be thinner; in this way, the air outlet volume of the air outlet slot 6 can be locally and individually controlled, so that the adjustment can be more flexible, and the control of the film bubble thickness can also be more convenient.
