First, the hats to be processed are placed in the placing frame 601. When the operator continuously takes the hats for processing, the fourth motor 607 can be started. When the output shaft of the fourth motor 607 rotates, the third screw rod 605 is driven to rotate. When the third screw rod 605 rotates, the thread drives the connecting block 603 to move upward. The connecting block 603 drives the slide plate 602 to move upward. When the connecting block 603 slides, the movement through the fixed frame 606 is more stable.

When the male buckle is located below the upper mold 15, At this time, since the connector 17 is connected to the air source, suction is generated by the air source to adsorb the male buckle on the upper mold 15, and then the push rod 504 moves backward, and then the third hydraulic rod 14 is started. When the telescopic end of the third hydraulic rod 14 is extended, it drives the upper mold 15 to move downward. While the upper mold 15 moves downward, the second hydraulic rod 10 is started. When the telescopic end of the second hydraulic rod 10 is extended, it drives the slider 9 to move upward, so that the slider 9 drives the female buckle to move upward, and at the same time, the air source generates thrust to install the male buckle and the female buckle together, completing the buttoning process, and the female buckle is pushed to the inside of the lower mold 8 by the push rod 504 to prevent the female buckle from flying. At the same time, the setting of the guide plate 505 prevents the female buckle from shifting when pushing the material.
