Machine brief description
The single sided paper lamination machine uses LDPE, LLDPE, PP, EVA, EAA and other coated resins as raw materials. It can be applied in nonwoven fabrics and bags and other products.
This machine has the functions of automatic tension control and automatic correction with an actual production speed of 180m/min.
Automatic adjustment of film thickness
A newly developed program has been added to the PLC system to enable the main engine and the traction mechanism to be linked together. During the running-in period, the equipment will automatically record the ratio of screw speed and traction speed for the raw material. Then, the film thickness adapted to different equipment speeds can be automatically calculated and transferred to the automatic mode. In automatic mode, the thickness of the film will always be the same no matter how the speed of the equipment changes during winding and unwinding.
Automatic shaft pulling
The smallest inner diameter of the inflation shaft of the high-speed lamination machine is 6 inches. The shaft is too heavy for manual lifting. Therefore, we have designed a fully automatic shaft pulling device to reduce labor intensity and improve safety.
Automatic tension control
The tension is controlled by the closed loop PLC system.
Automatic correction system
After the main unwinding, the paper roll must be automatically corrected to ensure the neatness. The choice of rectification device should be determined according to the difference of the base material, such as photoelectric correction, infrared correction, etc.
