Existing hot melt adhesive coating machines cannot adjust the position of the unwinding roller according to the size of the roll, resulting in ineffective unwinding of the roll and insufficient tension, which affects the uniformity of coating.
A hot melt adhesive coating machine unwinding device was designed. A cylinder drives a push rod to push a slider to slide in the unwinding groove, which in turn moves the unwinding roller. Combined with a tensioning motor driving a threaded rod to rotate, the tensioning roller slides in the groove, adapting to rolls of different diameters and materials, and ensuring that the rolls are evenly unwound.
It improves the flexibility and practicality of the equipment, enabling it to adapt to rolls of different diameters and materials, ensuring uniform coating, and increasing the yield.
