Industrial UV Drying Line Surface Printing Non-Standard Custom IR Three-Layer Tunnel Furnace

Function: The equipment is suitable for drying after printing ink on composite board and acrylic surface.

Equipment specifications and main technical indicators.
1. Use beige Teflon cloth conveyor net, net width 600mm
2. Automatic deviation correction is used to prevent deviation of the conveying net.
3. Adopt frequency converter to freely adjust the stepless speed, the speed range is 0.5-5m/min.
4. High-grade fully enclosed gear reducer motor drive.
5. Three-layer independent conveying mechanism, back-and-forth conveying.

Blanking method between layers
1. Use the roller pallet to cut the material, the third layer of material comes out and enters the blanking roller to the pallet, the pallet returns the product to the second layer for baking, and the second layer of material comes out into the blanking roller to the pallet , The pallet is returned and the product falls into the first layer for baking.

Structure distribution
1. External dimensions: L9000mm×W1500mm×H2150mm
2. Feeding section: 1500mm
3. Heating section: 5000mm (Equally divided into 3 sections, 3 layers of heating sections total 15000mm)
4. Cooling section: 500mm
5. Discharge section: 500mm
6. Material transfer layer: 1500mm
7. The conveyor net is above the ground: 1000mm

way to heat up:
1. The heating section is 5 meters in total, heated by hot air circulation, and the temperature of each section can be adjusted independently.
2. Adopt PID temperature controller, with SSR component phase output control, fast temperature control speed and high stability.
3. The surface temperature of commonly used materials is 80℃, and the temperature uniformity of the material surface is within ±3 degrees across the left, middle and right.
4. The set temperature in the furnace is max 120℃. The usual temperature is 80°C.
5. The heating section is equipped with rock wool insulation and air insulation, which has the lowest impact on the cold room, and 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 front and rear door panels are designed for easy maintenance.
8. The furnace adopts a blast circulating return air method to reduce heat loss and save energy.
9. Adopt horizontal air supply method.
10.The air duct in the furnace is equipped with a high-efficiency filter with a filtration efficiency of 99.97%, Class1000, and a temperature resistance of 250 degrees

The filter screen ensures the cleanliness of the furnace.
Air supply method: Using 1/2 HP high temperature long axis motor with wind wheel, horizontal air supply is blown to the surface of the product after high efficiency filtration.
Each temperature zone *1 group, a total of 3 groups, the air outlet is equipped with mesh screen to prevent product drift.
Conveyor belt cleaning: Use an electrostatic brush to clean the surface of the mesh belt, and use a box under the brush to drop the brushed dust into the box.
Cooling method: forced air cooling by fan.
Electric heating distribution: each layer is heated by infrared heating tube.

Furnace body material:
1. The exterior is made of steel plate with high temperature paint after anti-rust treatment, and the sheet metal sealing plate around the base
2. SUS201#1.5t mirror stainless steel plate is used inside.

protective device:
1. In addition to the main temperature control and the upper and lower limit over temperature prevention circuit, the over temperature protection is also equipped with a secondary temperature control
The over-temperature preventer is the safest temperature protector. When the over-temperature temperature is abnormal, the alarm will sound and the power will be automatically cut off.
Source system to prevent accidents.
2. The drive motor is equipped with reverse phase protection to prevent the motor from being too high after reverse phase, causing product defects and equipment damage.
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.
