Unwind & Rewind
- Tension control: Ultra-light floating roller control, automatic tension compensation, closed loop control; (Low-friction cylinder position detection, precision pressure regulating valve control, automatic alarm or shutdown when the coil diameter reaches the set value).
- Center drive unwinding, equipped with servo motor, closed loop control by frequency converter.
- It has the function of automatic shutdown when the material is interrupted, and the tension maintains the function to avoid the substrate slack and deviation during the shutdown.
- Configure automatic EPC
Printing Unit
- Type: CI Flex Printing Machine
- Drive mode: Gear Drive
- Motor: Servo motor drive, inverter control closed loop control
- Printing method :Photosensitive resin plate, suitable for both water-based and alcohol-soluble inks
- Printing Repeat: 400-900mm
- Repeat length: 5mm (for each tooth the length will increase or decrease 5MM)
- Printing pressure adjustment: Manual (automatic printing after pre-registration, automatic hydraulic reset when starting/stopping, printing immediately after starting, no need to register again, printing pressure/register are the same)
- Registration method: Online vertical and horizontal electric precise quantitative positioning and rapid plate registration, with automatic center return function
- Registration Precision:The color registration accuracy will not change when the speed is increasing or decreasing
- Central Drum:
Double-layer structure steel processed by multiple heat treatment and shaping process
Radial runout tolerance range is +/-0.010mm.
The surface plating layer reaches more than 200um
Inking System
- Chamber doctor blade with Two-way pneumatic diaphragm pump automatically circulates ink supply
- Anti-wrinkle device with curved rollers before printing
- Anti-static device before printing
Drying System
It adopts electric heating, which is converted into circulating air heating through a heat exchanger. The temperature control adopts an intelligent temperature controller, a non-contact solid state relay, and a two-way control to adapt to different processes and environmental production, save energy consumption, and realize PID temperature control. Temperature control accuracy ±2℃
Video Inspection System
Resolution 1280*1024
Magnification ·3-30 (referring to area magnification)
Display mode full screen
Image capture interval Automatically determine the image capture interval based on the position signal of the PG encoder/gear sensor
Camera inspection speed 1.0m/min
Inspection range
· According to the width of the printed matter, it can be set arbitrarily, and can be monitored at fixed points or automatically back and forth
