Overview
Rdc-01/500cs 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 integrates unwinding, dip coating, drying, Air-Cooled, vertical cutting and winding. The effective application width is 500mm. It adopts the immersion coating method, which is suitable for the processing of plain base paper or printing decorative paper.
Features
1. Single station unwinding unit, equipped with inflatable shaft and tension automatic Control system.
2. Using the immersion coating method, Spreader thickness can be adjusted according to the process.
3. External infrared heating and centrifugal fan hot air circulation, Temperature range.
4. Air-Cooled system and air knife cutting device, allowing for free control of cutting spacing.
5. Servo-controlled motor, the mechanical speed can be adjusted slowly to adapt to different process requirements.
Principle
The process flow of the equipment is unwinding → first dip coating → drying → second dip coating → drying → Air-Cooled → vertical cutting → winding. Automatic tension control is achieved through magnetic particle brakes and tension controllers, Teflon rollers are installed in front of the Spreader head, the heating system adopts infrared heating and hot air circulation, the Air-Cooled unit is chilled down, and the cutting device uses an air knife for slitting.
Applications
Melamine dipped paper process
Steps
1. Unwinding: use a single-station unwinding unit, the width of the substrate is less than 500mm, and the diameter is less than or equal to 400mm.
2. First dip coating: Spreader melamine formaldehyde Resin and urea formaldehyde Resin mixture by soaking.
3. Drying: heating and drying in the range of 50~ 150 ℃ +/- 3 ℃.
4. Second dip coating: repeability dip coating process.
5. Drying: heating and drying again.
6. Air-Cooled: Use the Air-Cooled system to chill down materials.
7. Vertical cutting: Cut through the air knife cutting device to control the cutting spacing.
8. Winding: The winding diameter is less than or equal to 500mm, and the edge uniformity is +/- 3.0mm.
Notice
- Pay attention to the diameter limit of the base material when unwinding and unwinding, the unwinding diameter is less than or equal to 400mm, and the winding diameter is less than or equal to 500mm.
- Spreader thickness needs to be adjusted according to the process to avoid exceeding the range.
- Heating Temperature range is 50~ 150 ℃, the maximum temperature in the intermediate temperature zone is 160 ℃, and the temperature needs to be precisely controlled.
The mechanical speed can be adjusted, and the production speed depends on the process, generally 0.1 to 1 m/min.
- The cutting device uses an air knife, and pay attention to safety spacing control during operation.
- Power supply voltage is three-phase five-wire 380V 50Hz to ensure correct connection.
- The total power of the equipment is about 40kW, and the electric Heating power is about 35kW. Pay attention to the load when using it.
