Overview
RDH-12/650 Automatic film applicator for large coils is a factory-sold automated coating equipment. Its Spreader program is unwinding, comma scraping, infrared drying (6 meters oven, 2 meters knots * 3), comma scraping, infrared drying (6 meters oven, 2 meters knots * 3) and winding. The roller heating temperature can reach 200 ° C. It is suitable for hot-melt adhesive films.
Features
1. Continuous Spreader program using double comma scraping and double infrared drying oven (6 meters each, 2 meters knots * 3).
2. The heating temperature of the rubber roller can reach 200 ° C, which is suitable for hot-melt adhesive film.
3. The coating speed can be adjusted within the range of 1~ 10m/min to adapt to different production needs.
4. The effective Spreader width is adjustable in the range of 100~ 650mm, and the Spreader Film thickness range is wide (0.005-3mm).
5. Equipped with trimming device, correction system and traction device to improve Spreader accuracy and stability.
6. Wide drying temperature range (RT +~ 200 ℃) to meet the drying requirements of various materials.
Principle
The equipment releases the coil through the unwinding device. Spreader is first carried out through the first comma scraper, and then enters the first infrared drying oven (6 meters, divided into 3 sections) for preliminary drying; then the second comma scraping is carried out, and then enters the second infrared drying oven (6 meters, divided into 3 sections) to complete the final drying. Finally, the coil after the Spreader drying is rolled by the winding device. During the whole process, the heating roller and oven provide the necessary heat to ensure uniform drying and curing of the coating.
Applications
Hot-melt adhesive film
Steps
1. Unwinding: Install the roll to be Spreader to the unwinding device.
2. First comma scraping: The coil passes through the first comma scraper for preliminary Spreader.
3. The first infrared drying: Spreader after the coil into the first infrared drying oven (6 meters, 2 meters section * 3) for drying.
4. Second comma scraping: The dried coil passes through the second comma scraper for secondary Spreader.
5. Second infrared drying: Spreader the coil into the second infrared drying oven (6 meters, 2 meters section * 3) for final drying.
6. Winding: Winding the completely dried coil by the winding device.
Notice
• The total power of the equipment is 45KW, and the 380V Power frequency is required. Please ensure that the power supply meets the requirements.
• The heating temperature of the drying tunnel and rubber roller can reach up to 200 ° C. Please pay attention to high temperature protection during operation.
