[0025] The working principle of the above embodiment is:

[0026] The film blowing cooling device is used for plastic film production. During the film blowing cooling process, the plastic film is rolled up by the winding roller 3, and the fan 4 is started to blow the outside air out through the air outlet mesh plate 5 to perform film blowing cooling on the plastic film. The threaded rod 15 drives the movable block 16 to slide in the second slide groove through the second slider, so that the position of the shielding mesh plate 8 can be adjusted, so that the air outlet holes between the air outlet mesh plate 5 and the shielding mesh plate 8 are staggered, thereby realizing the adjustment of the size of the blown cooling air, which is convenient for use in different usage situations. Through the provision of the dustproof net 14, dust in the outside air can be filtered to reduce the situation where dust is blown onto the surface of the plastic film. In addition, during the film blowing cooling process, the motor 6 is started to drive the movable block 16 to slide in the second slide groove through the second slider. The semi-bevel gear 7 rotates, so that the tooth plate 17 meshing with the semi-bevel gear 7 slides downward in the first slide groove through the first slider, and the tooth plate 17 squeezes the spring 18. When the semi-bevel gear 7 is no longer meshed with the tooth plate 17, the tension of the spring 18 drives the push plate 9 to reset and move upward, and the push plate 9 vibrates and cleans the water droplets or other impurities that may be attached to the surface of the plastic film to ensure the production efficiency of the plastic film. When the output shaft of the motor 6 rotates, the driving gear 10 rotates accordingly, so that the driven gear 12 meshing with the driving gear 10 rotates through the rotating shaft 11, driving the cleaning brush 13 on the outside of the rotating shaft 11 to rotate, and the dust attached to the dustproof net 14 is cleaned, so as to reduce the dust accumulation on the dustproof net 14 that affects the air intake effect, and facilitate the use of the user.
