1. Unwinding Part

• Unwinding method: The unwinding width is adjusted by rack type adjusting rod, unwinding tension adopted 10KG magnetic powder brake. The 1pc of rotary encoder/2pcs of load cell/ 1pc of tension amplifier combined with brake to realize control unwinding tension, to make film generate certain amount of tension, ensuring the appropriate film tensity. Loading material is via hydraulic type up and down swing mechanism to realize auto feeding material, so as to reduce labor intensity.

 

 

• Web guiding: Adopting CCD web guiding system, tracking material edge or printed line, with electrical fine tuning function, it allows machine to quick adjust photoelectric position to reduce cost and improve efficiency.

 

 

• Adjusting device: Unwinding aluminum guiding roller has lengthways adjusting devices, make material to the full extent of paralleling with guiding roller in order to ensure the rewinding accuracy and quality.
• Unwinding control: There are functions like start, stop, speed control and unwinding tension adjusting, synchronize with rewinding part, displaying machine speed, unwinding tension, rewinding tension, rewinding length.
• Unwinding splicing plate: Humanized slope pneumatic splicing plate is designed to quick splice material and to improve efficiency.

  

 

2. Traction Part

• Traction drive: Traction roller is individual driven by motor, arc-gear synchronous belt transmission torque, with its feature of lower noise, larger torque, less power loss.

 

 

• Traction roller: Traction roller is rubber roller, after dynamic and static balancing correction, the feature is stable operation, no vibration source, fits for wider range material and high-speed application.
• Traction lay-on roller: Traction lay-on roller is rubber roller, after dynamic and static balancing correction, pneumatic control for traction lay-on roller rising and falling, adjustable pressure.
• Measure length: The motor's Built-in encoder detects working length, with high precision and high resolution, accumulative measuring length, and automatic stop to the number.

 

3. Slitting Part

• Slitting method: Razor cutter. Groove roller after oxidation treatment to enhance rigidity and quality, specification is groove width 2mm and groove stem 1mm to fit for more kinds of materials.
• Quantities: With 10 sets of razor knife holder.
• Guiding rollers: transition transmission aluminum guiding roller, with diamond intersection line on surface, make material more smooth during high-speed rotation.

 

4. Trimming Edge Part

• Edge material treatment: Suction device is equipped with guiding tube to successfully suck out the edge material. The edge material exit is located on the right side of the machine. (The direction of the edge material exit can be customized)

 

5. Rewinding Part

• Rewinding method: Side-arm type unloading, with 3 inch pneumatic single-ball friction shaft, by pneumatic system drive automatic radial friction adjustment, offset tension changing caused by rewinding diameter changing, achieving automatic taper control.

 

 

• Rewinding drive: Upper and bottom Rewinding shafts are both individual driven by motor, arc-gear synchronous belt transmission torque, with its feature of lower noise, larger torque, less power loss.

 

 

• Paper tube positioning: Rewinding infrared paper tube positioning, ensure the right position of paper tube, minimize film loss, standard equipment of 8 sets.

 

 

• Back pressure roller: Rewinding contact pressure roller is controlled by air cylinder, contact roller is controlled by precision regulator valve, it is made of rubber and the air pressure can be adjusted according to rewinding requirements.
• Discharging rack: With horizontal rotary discharging arm function. Unloading finished rolls by manual unloading to the discharging rack, and the length of discharging arm is 1200mm.

 

 

6. Electrical and Pneumatic Part

• Drive: High performance motor combined with Yaskawa inverter is adopted to achieve high precision speed.
• Control: The host is controlled by PLC, set operating parameters on interface and monitor working status.

 

 

• Interface: It is able to save 10 sets of parameters with parameters saving function, easy for operators to read and use, reducing setting time and improving efficiency.
• Circuit layout: All circuits are enclosed laid to minimize human operate error.
• Pneumatic components: The selection and designing of pneumatic components is well considered, all electrical and pneumatic components are domestic and overseas famous brands due to the machine function have many automation and control.

 

7. Other Parts

• The machine wall is high strength and low stress. It is stable after twice stress relieving.
• SFAG/ Germany bearings are adopted in all spinning parts.
• All machine units are processed in CNC machine center.
• Emergency stop buttons are installed in operation side.
