At present, no other enterprise in domestic industry is able to produce a complete set of laminating film slicing machine due to many reasons, such as high cost, difficulty in operating and technological problems. Though similar equipments can be found in slicing machine industry, all of them adopt frequency inverter to drive the motor; therefore, it is hard to achieve high-precision control. Many enterprises demand innovation in slicing technology to increase production capacity, enhance precision and flexibility of slicing machine, reduce energy waste and strengthen the competitiveness in domestic industry.

1.2 Technical Parameters
Laminating film slicing machine is specially designed to slice laminating film. It adopts double baiting technology and the laminating film is cut in both vertical and horizontal directions, which is different from the method of paper cutting machine and greatly improves slicing precision and efficiency. The technical parameters of laminating film slicing machine are as follows:
Material thickness: 75 u~175u (single layer), double layer can be cut
Maximum width of coiled material: 950mm
Maximum diameter of coiled material: 650mm
Slicing speed: 60~100 pcs/min (depends on actual material)
Length of slice: 30~1,300mm
Cutting precision: ≤+/-0.1
The control system of laminating film slicing machine is shown in Figure 2.
The control system is composed of HMI, IVC1 PLC, I5300 frequency inverter, I100 servo drive. Since all devices are made by IACDRIVE, they are well compatible with each other.
