AI Technical Summary
In traditional cardboard processing equipment, the rollers make rigid contact with the corrugated cardboard during the rolling process, which causes irregular cracks on the cardboard surface. Furthermore, the roller spacing cannot be adjusted, affecting the quality of the carton and making it impossible to perform crease operations of different widths.
A cardboard folding machine was designed, which uses a lifting cylinder to drive the connecting rod and the creasing assembly to move. Combined with the eccentric setting of the limiting plate and bearing, the compression spring provides buffering to avoid hard contact between the roller and the cardboard. The position of the roller is adjusted by the slider and the bidirectional cylinder to adapt to the creasing requirements of different thicknesses and positions.
It enables flexible creasing operations on cardboard of different thicknesses, avoiding cardboard cracks caused by hard contact, improving carton quality and processing flexibility, and adapting to crease requirements of different widths.
