[0042] In this embodiment, the air blowing cooling mechanism includes a connection plate 3, an intelligent temperature control fan 4 fixedly mounted on the outer wall of the top of the connection plate 3, a filter housing 5 with a self-cleaning filter assembly inside, and a plurality of air expansion covers 7 fixedly connected to the top of the connection plate 3 and distributed at equal distances. The tops of all the air expansion covers 7 are fixedly connected to the same shunt pipe 6, and the intelligent temperature control fan 4 is electrically connected to the main controller 39 and is intelligently controlled by it;

[0043] Then, the cold air sent by the intelligent temperature control fan 4 is diverted to each air expansion hood 7 through the diverter pipe 6, and then evenly sent to the cooling area by each air expansion hood 7, thereby effectively improving the cold air delivery effect and improving the cooling efficiency of the food;

[0044] Further, the filter housing 5 is fixedly connected between the air outlet end of the intelligent temperature control fan 4 and the shunt pipe 6, and the self-cleaning filter assembly includes a filter screen 20 fixedly connected to and adapted in the filter housing 5, a support member 21 fixedly connected to the filter housing 5, a rotating shaft 22 rotatably mounted on the support member 21, and a turbine blade 23 and a cleaning brush 24 fixedly mounted on the rotating shaft 22 in sequence, and the bristle part of the cleaning brush 24 contacts the surface of the filter screen 20;

[0045] Then, the filter 20 in the filter housing 5 can be used to effectively filter the cold air delivered by the intelligent temperature-controlled fan 4, so as to avoid the situation in which dust and impurities are brought in during the cooling and delivery process and the transparent bagged food is polluted. The intelligent temperature-controlled fan 4 delivers the cold air into the filter housing 5, and the turbine blades 23 will rotate under the circulation of wind force, and then the cleaning brush 24 on the rotating shaft 22 will rotate to automatically clean the surface of the filter 20. In this way, the cleaning and anti-blocking effect of the filter 20 is achieved without the need for an additional driving source, and the filtering efficiency of the filter 20 is effectively guaranteed.

[0046] In this embodiment, the blowing height adjustment mechanism includes an infrared distance sensor 8 fixedly mounted on the outer wall of the bottom of the connecting plate 3, two threaded adjustment components and a synchronous drive component.

When the blowing height adjustment mechanism is working: the driving sprocket 13 is controlled to rotate by the first stepper motor 12, and then the two driven sprockets 14 control the two threaded vertical rods 9 to rotate synchronously under the transmission effect of the chain 15. Under the limit of the slide slot, the two adjustment blocks 10 threadedly connected with the two threaded vertical rods 9 drive the connecting plate 3 to move linearly, and then the lifting and lowering movement effect of the connecting plate 3 can be achieved only by the positive and negative rotation effect of the output shaft of the first stepper motor 12.

[0050] Then, the infrared distance measuring sensor 8 can automatically detect the incoming transparent bagged food, and the detection result is transmitted to the main controller 39, which controls the operation of the blowing height adjustment mechanism, so that the blowing height can be flexibly adjusted to a suitable height for transparent bagged foods of different heights, which can effectively improve the cooling efficiency;

[0052] Then, the transparent bagged food delivered at the front end of the conveyor belt 2 is visually inspected by the front-end visual inspection component, and different types of food can be automatically identified, and the inspection information will be transmitted to the main controller 39. The main controller 39 will analyze and process and control the operation of the intelligent temperature control fan 4, and then the intelligent temperature control fan 4 will automatically adjust the cooling temperature according to the characteristics of different foods, so as to ensure that different foods are cooled at a relatively suitable temperature, which can effectively improve the freshness and taste of the food.

[0058] In the specific implementation of this embodiment: the cooled transparent bagged food is automatically inspected by the rear-end visual component, and the detected image information is transmitted to the main controller 39 for processing, and the main controller 39 controls the operation of the selection mechanism, that is, when the transparent bagged food is detected as a high-quality product, the sliding block 29 will slide to the rear end, and then the telescopic end of the electric push rod 31 controls the push plate 32 to descend to the lowest point and move forward to gradually push the transparent bagged food blocked by the blocking plate 25 to the high-quality product guide inclined plate 33;

[0059] On the contrary, when the transparent bagged food is detected as a defective product, the sliding block 29 will slide to the front end, and then the telescopic end of the electric push rod 31 will control the pushing plate 32 to drop to the lowest point and move backward to gradually push the transparent bagged food blocked by the blocking plate 25 to the defective product guiding inclined plate 34.
