AI Technical Summary
During the inversion process of existing wrapping machines, the film is prone to shrinkage, wrinkling or loosening, which affects the tightness and appearance of the packaging. At the same time, uneven stress on mechanical parts leads to increased wear, affecting the stability and lifespan of the equipment.
A pre-stretch winding machine was designed. By rotating the rotating teeth on the inner wall of the fixed plate and setting the actuating plate and spring structure on the support shaft, the stable rotation of the rotating shaft is ensured. At the same time, an adjustment mechanism is set on the fixed plate to adapt to the winding materials of different heights, so as to achieve precise positioning and height adjustment.
It effectively prevents the film from shrinking or loosening during inversion, improving the tightness and appearance of the packaging, while reducing wear on mechanical parts and enhancing the stability and service life of the equipment.
