Overview
Rdc-02/500clcs immersion coil drying Air-Cooled slitting machine is a factory direct sales product, mainly suitable for the process flow of melamine dipped paper. The equipment adopts a complete process chain of unwinding → 1 dipping → 1 drying → 1 chilling down → 2 dipping → 2 drying → 2 chilling down → correction → traction → cross cutting, with an effective application width of 500mm.
Features
1. Using immersion coating method, Spreader thickness can be adjusted according to the process
2. Equipped with external infrared heating and centrifugal fan hot air circulation system, Temperature range 50~ 150 ℃ +/- 3 ℃
3. Integrated Air-Cooled chilling down system and cross cutting device
4. Automatic tension control, using magnetic particle brake and tension controller
5. Mechanical speed 1.2m/min, production speed 0.1~ 1m/min can be adjusted slowly
6. Equipped with 4 Teflon rollers, each installed in front of the Spreader head
Principle
The equipment develops the substrate through the unwinding unit, and goes through two cycles of impregnation, drying and chill down. After the first impregnation, it enters the drying area for infrared heating and hot air circulation drying, followed by Air-Cooled chill down; the same process is carried out for the second time, and finally the slitting is completed through deviation correction, traction and cross-cutting. The whole process is controlled by automatic tension control and precise control of servo motor.
Applications
Production process of melamine dipped paper
Steps
1. Unwinding: Development of Substrate from Unwinding Unit
2.1 Impregnation: The substrate is immersed in glue for the first time
3.1 drying: infrared heating and hot air circulation drying
4.1 chill down: Air-Cooled system chill down
5.2 impregnations: the substrate is immersed in glue for the second time
6.2 drying: infrared heating and hot air circulation drying again
7.2 chill down: Air-Cooled system chill down again
8. Correction: adjust the coil position
9. Traction: Servo motor controlled traction
10. Cross-cutting: Cross-cutting knife completes slitting
Notice
• The width of the substrate should be less than 500mm
• The unwinding diameter does not exceed φ 400mm
• The winding diameter does not exceed φ 500mm
• The production speed range is 0.1~ 1m/min, which needs to be adjusted according to the process
• Operating temperature range is 50~ 150 ℃, the maximum in the middle temperature zone is 160 ℃
• Use three-phase five-wire 380V 50Hz power supply
• The curling edge alignment is controlled within the range of +/- 3.0mm
