[0002] In the related art, beverage bottles are usually packaged with heat shrink film, specifically, the heat shrinkability of the heat shrink film is used to package beverage bottles. When the heat shrink film is used to package beverage bottles, an air supply device is required to directional deliver hot air. However, the traditional air supply device has the following problems: 1. The traditional air supply device cannot adjust the air supply volume, that is, the air supply volume of the traditional air supply device is fixed, resulting in unstable packaging effect of the heat shrink film, which makes the final product yield rate low, thereby reducing processing efficiency and increasing processing costs; 2.

[0030] Reference Figures 1 to 5 According to an embodiment of the present application, the adjustable air supply device includes an air box body 100 and a damper assembly.
[0031] Specifically, the air box body 100 is an internal hollow structure, the air box body 100 has an air outlet surface 110 and an air inlet interface 120 connected to the internal space of the air box body 100, the air inlet interface 120 of the air box body 100 is used to connect to the hot air source, the damper assembly includes at least two dampers 200 arranged side by side along the height direction of the air box body 100 (i.e., the X direction in the figure), the damper 200 is slidably connected to the air outlet surface 110 of the air box body 100, and the damper 200 can slide relative to the air box body 100 in a direction perpendicular to the height direction of the air box body 100 (i.e., the Y direction in the figure), and the air box body 1 00, a plurality of first air outlet holes 111 connected to the internal space of the air box body 100 are arranged at intervals corresponding to each air door 200, and the air door 200 is provided with second air outlet holes 210 corresponding to the corresponding plurality of first air outlet holes 111.

[0032] During use, when a certain damper 200 slides relative to the air box body 100 to a position where all of its second air outlet holes 210 overlap with all of the corresponding first air outlet holes 111, the damper 200 is in an open position, and when a certain damper 200 slides relative to the air box body 100 to a position where all of its second air outlet holes 210 and all of the corresponding first air outlet holes 111 are misaligned, the damper 200 is in a closed position. Among them, the degree of overlap between all of the second air outlet holes 210 of a certain damper 200 and all of the corresponding first air outlet holes 111 (i.e., the size of the overlap area between the second air outlet holes 210 and the corresponding first air outlet holes 111) can be adjusted to adjust the size of the air supply volume of the damper 200. In addition, dampers 200 of different heights can be selectively opened to adjust the air supply height.
