II. Sectores y materiales aplicables

Q3: : What materials can UV1‑2440 process and in which industries is it mainly used?

A3: It is mainly used for surface activation of sports shoe soles, Mould Wedge, EVA, MD and other foamed shoe materials to improve adhesion with glue. It is also applicable to UV curing in printing (ink curing), packaging (coating drying), electronics (component encapsulation) and other fields.

三. Working Principle & Features

Q4:: What is the curing principle of UV1‑2440?

A4:The specially formulated UV‑curable primer is evenly applied on the shoe material surface. After drying, the material enters the irradiation zone. UV light from four lamps splits the photoinitiator to generate free radicals, triggering polymerization and grafting polar groups onto the material surface, thus increasing polarity and adhesion. The three‑dimensional lamp housing layout (front, rear, left, right) ensures uniform irradiation from multiple angles.

Q5:  What are the outstanding features of UV1‑2440?

A5:

1. High efficiency & fast: Irradiation within seconds, greatly shortening production cycle.

2. Low‑temperature treatment: Cold‑source curing with low temperature avoids shrinkage, deformation or blistering of heat‑sensitive materials.

3. Three‑dimensional irradiation: Four independent adjustable lamp housings (height, angle, width) adapt to various workpiece shapes.

4. Stable conveying: Equipped with anti‑deviation device and stainless steel mesh belt for smooth passage.

5. Energy‑saving & economical: Instant lamp start, concentrated energy consumption, compact footprint.

6. Intelligent control: Each lamp independently controlled with ammeter monitoring; lamp failure alarm; over‑temperature protection; high/low power selection (for black/white heat‑sensitive materials).

7. Safety protections: Leakage protection, motor overload, emergency stop, phase loss and reverse prevention.

四. Installation & Operation

Q6: What utility conditions are required for UV1‑2440?

A6:Power: AC380V/50Hz/3Ph, total approx. 12.8KVA, with appropriate circuit breaker. Exhaust: Must connect Φ10″ (254mm) exhaust duct to outdoors; if duct length >5m or elbows >3, an auxiliary exhaust fan (2HP) is required. No cooling water needed. Machine must be properly earthed (ground resistance <100Ω). Installation environment should have good ventilation, no corrosive gases, ambient temperature below 30℃, and at least 60cm clearance from walls.

Q7:What key preparations and precautions are required before operation?

A7:

• Verify power supply matches nameplate and earthing is proper.

• Check rotation direction of exhaust and blower motors matches arrows (otherwise overheating).

• Adjust light shield according to workpiece height and close UV chamber door to prevent UV leakage.

• Adjust lamp housing height (normally 100‑120mm from workpiece) and angle.

• Check over‑temperature protector setting (normally 150℃) and temperature sensor connection.

• Operators must wear UV‑protective goggles and avoid skin exposure.

• Start‑up procedure: Power on → Press start switch → Conveyor runs → Set speed → Turn UV on → Wait 2‑3 min until “Ready” light → Select high/low power → Start production.

Q8:What should be noted when shutting down?

A8:Turn off UV switch first, then press stop switch. The exhaust fan will continue to run for 6‑8 minutes to cool the lamps, then automatically cut off power. Do not cut off power directly while lamps are hot – this will shorten lamp life. When not used for long periods, turn off the main leakage circuit breaker.

五.Maintenance & Care

Q9: What are the daily maintenance items for UV1‑2440?

A9:T

• Per shift: Clean dust and oil from conveyor belt; check light shield and UV chamber door seal.

• Weekly: Wipe lamp glass and reflector with industrial alcohol; clean UV chamber interior.

• Monthly: Clean electrical control box dust; check terminal tightness; use compressed air to clean cooling fans and vents.

• Quarterly: Clean impeller blades of exhaust/blower motors; check exhaust duct unobstructed.

• Half‑yearly: Replace reducer lubricant (per manual); check chain tension and lubricate; replace reflectors (recommended every 6 months).

• Yearly: Full inspection of electrical components; replace magnetic contactors (recommended annually).

• Lamp replacement: Lamp life approx. 800‑1000 hours; replace all 4 lamps when due.

Q10: What precautions should be taken when replacing lamps?

A10:

• Turn off main power and allow lamps to cool completely (at least 10 min).

• Wear clean gloves; do not touch quartz glass with bare hands (fingerprints cause hot spots and breakage).

• If touched, wipe with alcohol gauze.

• Confirm new lamp model CS‑101 (2kW) and tighten terminal screws at both ends.

• After installation, check lamp secure and reflectors clean.

• Run a short test to verify normal lighting and ammeter readings.

六.Troubleshooting

Q11: What to do if UV lamps fail to light or are abnormal?

A11:

• Check main power and leakage circuit breaker.

• Check lamp failure indicator for specific lamp number.

• Inspect lamp for blackening, cracks or end‑of‑life.

• Check terminal connections at both ends.

• Check ballast, capacitor, magnetic contactor for faults.

• If all normal, possible trigger or control circuit issue – contact professional service.

Q12: What to do if conveyor belt stops or cannot be adjusted?

A12:

• Check emergency stop button.

• Check conveyor motor power and starting capacitor.

• Check speed controller and variable resistor.

• Check chain for jamming or slack; adjust tension.

• Check motor overheating (cool and restart).

• If persists, check relays, magnetic switches and control circuit.

Q13: What to do if exhaust/blower motor does not run?

A13:

• Check power and fuses.

• Check magnetic switch and relay.

• Check motor windings (resistance measurement).

• Check thermal overload relay – reset and test.

• Note: If rotation is reversed, swap phases to correct; otherwise overheating will occur.

Q14: What to do if over‑temperature alarm occurs?

A14:

• Check over‑temp protector setting (normally 150℃).

• Check exhaust system for blockage or motor failure.

• Check blower motor and air inlet obstruction.

• Check air damper position.

• Check reflectors for dirt causing heat buildup.

• After resolving, wait for temperature drop and over‑temp light off before restart.

七.Model Selection & Production‑line Matching

Q15: What are the main differences between UV1‑2440 and UV1‑1600? How to choose?

A15:

• UV1‑1600: 4kW, 1kW×4 lamps, length 1.6m, irradiation width 430mm – suitable for small batches or medium workpieces.

• UV1‑2440: 12kW, 2kW×4 lamps, length 2.44m, irradiation width 430mm – longer, higher throughput, stronger three‑dimensional irradiation and better temperature control.
  Selection basis: production speed, workpiece size, required UV dose, and line space. For higher output and more uniform 3D irradiation, UV1‑2440 is recommended.
