PCB circuit board post-curing (text post-baking) tunnel oven
Xinjinhui tunnel oven
1. Application scope: PCB circuit board text post-baking (Post-curing), after exposure and development, dry the wet ink
II. Process flow: single-machine text screen printing machine/two-machine text continuous printing machine/text printer tunnel furnace
III , Baking method: high-speed circulating hot air
IV. Product features: energy saving of more than 35% (patented heating element, wind wheel), intelligent temperature control, triple safety protection
1. Heating System: Uses patented energy-saving heating element for heating.
2. Temperature control system:
·Adopt human-machine interface PLC temperature acquisition module to automatically control the temperature;
·Adopt solid-state relay control, precise temperature control, Air movement on both sides ensures temperature balance and accuracy.
·When the temperature does not reach the set temperature, the conveying system stops to prevent the board from not drying.
3. Conveying system: Using a page-turning belt chain conveying method to achieve the effect of drying and speeding up the drying speed;
4. Exhaust system: above each section of the furnace body Equipped with exhaust control valve.
5. Fault system:
·Has over-temperature indication and alarm function; there are two groups of over-temperature protection, one in the furnace and one in the heating body;
·It has functions such as leakage and motor overload protection. The heating body has an over-temperature system and an automatic power-off function.
6. Thermal insulation system: Using high-temperature silicic acid insulating rock wool to achieve good thermal insulation effect.
7. Energy-saving and emission-reduction design:
·Sleep mode when the heating body reaches the predetermined temperature
·When the detection board enters the warehouse, the temperature will be automatically heated by warehouse. Energy-saving control mode
·Energy-saving control mode that automatically turns off heating by warehouse when the board is detected to be out of the warehouse
