AI Technical Summary
Existing die-cutting devices with double-sided adhesive backing are prone to adhesive overflow when the die-cutting blade comes into contact with the adhesive, resulting in reduced die-cutting blade efficiency, shortened lifespan, and increased cleaning difficulty.
The die-cutting blade is driven up and down by a hydraulic cylinder. Combined with a transmission component, linear movement is converted into rotation, which drives the rack to move horizontally. A cleaning component is provided to clean the glue on the die-cutting blade. At the same time, the pressure component and damping spring ensure the stability of the product position and the quality of the punching.
It effectively prevents glue buildup, improves the efficiency and lifespan of die-cutting blades, ensures product quality, reduces manual cleaning workload, and enhances the overall performance of the punching and cutting device.
