The rise of the lifting door 2 makes the storage box 1 in an open state, and then the tool change operation is performed. After the tool change is completed, the lifting door 2 is operated again so that the lifting door 2 seals the storage box 1. The humidity inside the tool magazine is monitored in real time by the humidity sensor 20. When the humidity exceeds the set threshold, the dehumidification device 19 automatically starts to reduce the humidity inside the storage box 1, providing an effective moisture-proof measure for the tool body 16, protecting the tool body 16 from the influence of environmental humidity, and ensuring tool performance and processing quality.
