Product Specification

Intelligent Constant Temperature Electroplating Drying Oven Electronic Products Industrial Oven

Equipment overview
For baking printing ink on glass surface
The material is discharged after being heated and cooled by the conveyor belt through the infrared drying oven
The infrared drying oven is heated by infrared, the surface temperature of common materials is 180 ℃, and the surface temperature of the materials is uniform within 3 +/- 3 ℃.

Equipment specifications and main technical indicators

Delivery method
1. It is conveyed by beige Teflon cloth conveyor belt with a net width of 900mm.
2. There is an automatic adjustment mechanism for net deviation and limit protection.
3. Adopt the frequency converter to freely adjust the stepless speed, the speed range is 0.2-5m/min.
4. High-grade fully enclosed gear reducer motor drive.
5. Install a sticky paper roll at the bottom of the feed inlet to clean the conveyor belt.

Structure distribution
1. External dimensions: L6000mm×W1760mm×H1650mm
2. Feeding section 500mm
3. Heating section 4000mm (2 temperature zones are divided equally)
4. Cooling section 1000mm
5. Discharge section 500mm
6. The height of the conveyor belt from the ground is 950±20mm

way to heat up
1. The heating section is 4 meters in total, and it is heated by infrared radiation and electric heating cycle, which can control the infrared separately
Line output.
2. Using PID temperature controller, with SSR component phase output control, temperature control speed
The speed is fast and the stability is high.
3. The surface temperature of commonly used materials is 180℃, and the temperature of the material surface is within ±3℃ evenly across the left, middle and right.
4. The set temperature in the furnace is max 220℃. The usual temperature is 180℃.
5. The heating section is equipped with rock wool thermal insulation and air insulation, which has the lowest impact on the cold room. The surface temperature is 10℃ higher than the room temperature.
6. The intake and exhaust air doors can be adjusted to effectively control the micro pressure in the furnace.
7. The opening of the upper cover adopts electric cylinder to automatically lift, which is easy, safe and convenient.
8. The furnace adopts a blast circulating return air method to reduce heat loss and save energy.
9. The hot air is designed from top to bottom. Prevent material displacement and prevent dust from rising.
10. The air duct in the furnace is equipped with a high-efficiency filter with a filtration efficiency of 99.97%, Class1000, and temperature resistance
250 degree filter to ensure the cleanliness of the furnace.
Air supply method 1. Adopt 1/2 HP high temperature long shaft motor with wind wheel, after high efficiency filtering from top to bottom
Blow to the surface of the product and recover from the bottom. Each temperature zone * 2 groups, a total of 2 groups.

cooling method
1. Use a powerful fan to blow on the surface of the product to cool.
2. A powerful fan is used at the bottom to exhaust the hot air out of the room and convection up and down.
Electric heating distribution 1. Infrared heating tube 0.7KW*18 pcs/group, totally 2 groups. Infrared heating tube.

Furnace body material

1. The exterior is made of steel plate after anti-rust treatment and high temperature paint, and the sheet metal sealing

plate around the base
2. SUS201#1.5t mirror stainless steel plate is used inside.

Protection device

1. In addition to the main temperature control and the upper and lower limits of the
Temperature control over-temperature preventer as the safest temperature protector, abnormal over-temperature temperature
When the alarm sounds, the power system is automatically cut off to prevent accidents.
2. The drive motor is equipped with reverse phase protection to prevent the motor from overheating after reverse phase, causing damage to the product and equipment.
3. Equipped with an emergency stop switch, each heating section circuit overcurrent, overload protection and interlocking.
4. When an abnormality occurs, the abnormal indicator and buzzer alarm are used to facilitate the operator to eliminate the abnormality.
