AI Technical Summary
Existing punching and binding machines cannot flexibly adjust the number of holes and lack optimized control over the punching sequence, resulting in inconvenience in use; the ring pressing mechanism is difficult to adapt to the binding needs of iron rings of different sizes, affecting the binding quality and aesthetics.
Design a punching and binding machine. The starting and stopping control of the punching knife is realized by the drive mechanism driving the limit plate and the adjusting pin. The punching sequence is optimized by the abutment or sliding of the adjusting pin and the limit groove. The pressing ring mechanism realizes the precise adjustment of the pressing ring stroke through the drive mechanism and the transmission gear system.
It enables flexible control of the number of holes and optimization of the hole-punching sequence, improves ease of use and binding quality, adapts to the binding needs of iron rings of different sizes, and ensures the pressing effect.
