QZD-68 automatic paper cone production line doesn need any manipulation after putting raw material paper into it .The production progress is operated by PLC system, the principle machine transmission use cam to distribute time structure. Mechatronics is made up by different service position working principle,double -speed variable frequency control and photo-electric detection approach control, pneumatic time delay control. It makes the labor-saving, energy-saving, high-efficiency, high-quality paper cone production come true.
