LWF450 solventless composite equipment is a special equipment that combines two or more kinds of base materials by solvent-free adhesive. It has been widely used in food packaging, drug packaging, medical packaging, pesticide packaging and other industries.
1. The independent single station unwinding unit is favorable for the stability of the machine.
2. Unwinding type: there is a shaft in the center for winding, the air expansion shaft is keyway type, safety chuck, belt drive.
3. The unwinding is driven by the motor, and the unwinding is active and controlled by PLC.
4. Tension control: In order to control the tension of the unwinding material, the LWF450 solventless composite equipment adopts the floating roll tension control, equipped with Japanese SMC precision pressure regulating valve and low friction cylinder, and the PLC programmable controller realizes the tension control.
5. Before the unwinding material is nearly used up, the automatic alarm function is set to remind the operator.
6. EPC device is set for unwinding, and the detection head is an ultrasonic sensor for edge detection.
7. The adjusting roll is set after unwinding.
8. Unwinding is equipped with an electrostatic rope device.
9. Unwinding can be conducted on both sides.
