Overview
Oven Slot-die Automatic Film Applicator is a composite Spreader for non-elastic materials such as paper, film, aluminum foil, plastic, non-woven fabrics, etc. The device integrates unwinding, slot-die scraping, drying, overlaying and rewinding functions. The automated slot-die coating method can achieve efficient and uniform Spreader and composite production.
Features
1. Multi-functional integration: It has the functions of unwinding, scraping, drying, overlaying and winding.
2. Advanced coating method: Slot-die Spreader technology is adopted, and Spreader is uniform and accurate.
3. The drying system is controllable: the drying temperature range is wide (room temperature to 200 ° C), which can be adjusted according to the process requirements.
4. Excellent composite performance: The heating temperature of the composite rubber roller can reach 200 ° C to ensure that the composite film is gluing firmly.
Flexible operation adjustment: Fitting speed (1~ 10m/min), Spreader Film thickness (0.005-3mm optional) and other parameters can be adjusted.
6. Drive stability: stepper motor drive, high control accuracy.
Principle
When the equipment is working, the substrate is stably output from the unwinding device, and through the slot-die Spreader system, the molten polyethylene (PE) plastic is evenly Spreader on the surface of the substrate. Subsequently, the substrate after the Spreader enters the drying system, and the coating is cured by electric heating or hot air circulation. The cured material enters the composite device and is pressed with another layer of substrate under the action of the heated composite rubber roller to form a composite film. Finally, the finished film roll is neatly collected by the rewinding device.
Applications
Spreader and composite processing of non-elastic materials such as paper, film, aluminum foil, plastic and non-woven fabrics
Steps
1. Install the substrate reel to be compounded on the unwinding device and adjust the tension.
2. According to the process requirements, set the Spreader parameters (such as Film thickness) of the slot-die Spreader system.
3. Set the heating temperature and drying time of the drying system.
4. Set the heating temperature and bonding pressure of the rubber roller of the composite device.
5. Set the tension and winding speed of the winding device.
6. Start the equipment, start running at low speed, and observe the effects of Spreader, Drying, and Composite.
7. Gradually adjust to the target production speed (1-10m/min) for continuous production.
8. After production, shut down each system in turn and collect the finished film roll.
Notice
• This device is suitable for non-elastic materials, do not use for resilience material Spreaders.
• Make sure the Power frequency (220V) matches the equipment requirements before operation.
• When setting the temperature of the drying tunnel and rubber roller, do not exceed the maximum limit of 200 ° C.
• During the operation of the equipment, do not touch high-temperature components (such as drying tunnels, heating rollers).
• Spreader Film thickness and other parameters are optional ranges, and the actual customization shall prevail.
Equipment dimensions are for reference only, the actual size may vary depending on customization.
• The maximum discharge and receipt width is 850mm, please do not use it beyond the limit.
• Regularly check the tension and alignment of each roller to ensure smooth operation.
