The invention discloses a leather material cooling mechanism. The leather material cooling mechanism comprises a box body (1) provided with an opening and an outer sealing cover (2) sealing the opening of the box body (1); an annular cavity (5) is formed in the inner side of the box body (1), an inner sealing cover (3) sealing the opening of the box body (1) is arranged in the box body (1), and a circular cavity (6) is formed between the inner sealing cover (3) and the outer sealing cover (2); and the box body (1) is composed of a first air inlet and a first air outlet which enable the annular cavity (5) to communicate with the outside, and the outer sealing cover (2) is composed of a second air inlet and a second air outlet which enable the circular cavity (6) to communicate with the outside. By adoption of the above structure, the leather material cooling mechanism is simple in whole structure, convenient to achieve, and enables leather materials in the box body to maintain a long cooling time.
