[0012] In this utility model, a punching device for zippers on bag products is provided. Through the cooperation of a drive motor, screw, threaded sleeve, limiting rod, and punch block, the punch block moves downward, thereby pushing the upper die base and punch die downward. This causes the guide rod and guide plate to slide in a direction within the guide sleeve, thus squeezing the return spring. This allows the punch die to perform a punching operation on the zipper body and the bag. After punching, the drive motor is activated to rotate the punch block, allowing it to move upward under the constraint of the screw, threaded sleeve, and limiting rod. Then, under the action of the return spring, the guide plate drives the guide rod, upper die base, and punch die to reset, preparing for the next punching operation. This significantly shortens the time of each punching cycle, ensures long-term stable operation of the equipment, and improves the reliability and stability of the production process.

[0013] This utility model features a reasonable structural design. Through the cooperation of the throttle, worm gear, and other worm gears, a bidirectional lead screw is driven to rotate. The moving plate, bidirectional lead screw, and base frame work together to cause the moving plate to drive the moving seat and clamping plate to move closer or further apart along the axial direction of the bidirectional lead screw and under the constraint of the sliding groove. This allows for adjustment according to different sizes of lower die bases, achieving stable clamping and positioning of the lower die base and the bag product body placed on it. Stable clamping and positioning effectively prevents displacement or shaking of the bag product body during stamping, ensuring the quality of zipper stamping and installation, reducing the defect rate, improving product consistency and reliability, and enhancing the equipment's adaptability to different products. Factories no longer need to purchase different zipper stamping equipment for different sizes of bag products, reducing equipment procurement costs. Attached Figure Description
