1650-100 Dye sublimation paper coating machine
Product Description
1. The technical characteristics
1.1 Tension control:
Through programmable logic controller (PLC), touch screen and high precision converter special for tension, rotary encoder, proximity switch and tension sensor signal, it can achieve closed-loop tension control, reducing breaks in production process and increasing productivity and yield.
1.2 The machine control system:
Application of programmable logic controller (PLC), touch screen and
high performance digital frequency converter constitute the machine
stable control of running speed and the division tension; simple operation,
high automation degree, all the parameters have been set in the best state
in factory; only to input the speed, tension and other data, the machine
can achieve dynamically synchronous and automatic control.

4.4 Drying system
4.4.1 Hot air oven, 3 sets
Hot air dryer of floatation type, made of welded profile steel, inner surface coated by 1mm steel plate, out surface by stainless steel, in the middle it is 50mm insulation materials to ensure the out temperature and ambient air temperature does not exceed 20ºC. Air ducts made of 1mm galvanized steel plate. Spray nozzle is made of 1.5mm profile aluminum alloy with uniform gap. Spray slit width, 2.5-3mm.
The front and back wind pressure is regulated by the ventilation door at the air duct, flow speed 20-50m/s.
4.4.2 Hot air recycling system, 3 sets
Mainly composed by oven box, fans, gas burner and air duct etc. If choose the burners, the air stove is direct-fired type, no heat exchange equipment, the system automatically controls the switch, gas and energy efficiency is high.
