Overview
RDH-10/500clet Automatic film applicator is a factory-sold automated coating equipment. Its Spreader program is complete, including unwinding, comma Blade Coating, infrared heating stoving, hot-melt adhesive Spreader, chill down, laminating, trimming and winding. The effective Spreader width is 500mm, and the roller heating temperature can reach 200 ° C. It is specially designed for hot-melt adhesive film processes.
Features
1. Integrated Spreader program: covering the entire process of automation from unwinding to rewinding.
2. Efficient heating system: equipped with 10 meters infrared oven, drying temperature up to 200 ℃, to meet the requirements of hot-melt adhesive process.
3. Accurate Spreader Control: Comma Blade Coating and Adjustable Blade Coating device, Spreader Film thickness range is wide (0.005-3mm).
4. Stable operation guarantee: built-in correction system, traction device and trimming device to ensure production continuity and finished product mass.
5. Flexible and adjustable: coating speed (1~ 10m/min) and effective Spreader width (100~ 500mm) can be adjusted according to demand.
Principle
The device completes the coil Spreader through an automated process. First, the substrate is drawn from the unwinding device and preliminarily precise Spreader is carried out through a comma drawdown blade. The material after the Spreader is then heated into a 10-meter-long infrared oven for curing or activation. Next, a secondary Spreader (if required) is carried out by the hot-melt adhesive Spreader head, and then chilled down through a 2-meter Air-Cooled zone. The chilled down material is bonded to another layer of material (if required). After the edge is cut by the trimming device, the finished product is finally rolled up by the winding device.
Applications
It is suitable for coil processing fields that require hot-melt adhesive film, compounding, lamination and other processes.
Steps
1. Prepare the coil and install it correctly on the unwinding device.
2. According to the process requirements, set the comma Blade Coating parameters (such as Film thickness).
3. Set the heating temperature of the infrared oven and rubber roller (up to 200 ° C) and the coating speed (1~ 10m/min).
4. Adjust the drawdown blade device of the hot-melt adhesive Spreader head.
5. Start the equipment, and the material goes through Spreader, stoving, secondary Spreader, chill down, bonding and trimming processes in turn.
6. Monitor the operation through the deviation correction and traction system, and finally complete the finished product collection by the winding device.
Notice
• Power frequency of the equipment is 380V, total power 45KW, need to ensure that the power supply matches.
• Before operation, confirm that the parameter settings such as Spreader width, Film thickness, temperature and rate meet the process requirements.
• The maximum discharge and receipt width is 550mm, please do not use it beyond the limit.
• Drying tunnel and rubber roller high temperature, please pay attention to safety during operation to prevent burns.
• The dimensions and weight of the equipment are subject to the actual customization, and enough space should be reserved during installation to ensure that the ground bears weight.
• Regularly maintain the correction system, traction device and trimming device to ensure their operation accuracy.
