Introduction to Fully Automatic Production Line

In the fast-paced world of candle manufacturing, efficiency, consistency, and scalability are the keys to staying competitive. Dongguan Yide Machinery Co., Ltd. has addressed these needs with its Full-Auto Production Line—a integrated solution combining a 12-nozzle filling machine, feed cup device, and pre-heating device. Designed to handle wax filling, jar feeding, and pre-heating in one seamless workflow, this line eliminates manual bottlenecks, boosts output, and ensures uniform product quality—making it a game-changer for medium to large candle producers.

12 Nozzles Filling Machine

Structure

How to Operate

1. Tank Preparation: Add water/conduction oil to the warming tank jacket (up to 80% level), then clean the tanks with water (drain via discharge valve).

2. Machine Connection: Plug in 380V power and connect the air compressor (≥6P).

3. Positioning & Height Adjustment: Place the filling machine on the 24-meter line (near the pre-heating device), then use the touchscreen to adjust filling height (long-press “Fill Tank Up/Down”).

4. Wax Loading: Connect the warmer tray to the wax melting tank, pump molten wax into the side warm tank, then transfer it to the fill tank (manual pump for first use, auto pump during production).

5. Temperature & Calibration:

Turn on “Pump Heater,” “Filling Tank Heater,” and “Wax Tank Heater” switches to heat wax.

Switch to Manual Mode: Press “Pick up cylinder” for 2 seconds, then test each pump (place a jar under nozzle #1, weigh the fill, and adjust via the Parameter Screen: enter password “1212,” tweak “Quantitative” values to match target weight).

6. Auto Operation: After all pumps are calibrated, switch to Auto Mode, turn on the conveyor belt (adjust speed), and press “Start” to begin filling.

How to Operate

1. Jar Adaptation: Adjust the guard bar to fit the jar size, then install the sensor (ensure it stays green).

2. Mode Selection: Use the PLC screen to choose Rotary Mode (2OZ jars) or Cylinder Mode (1OZ jars).

3. Parameter Setup: Input data (e.g., feed delay, turntable speed) via the Parameter Screen—reference Yide’s recommended settings (1OZ: Cylinder Mode, 2OZ: Rotary Mode).

4. Test & Run:

Place jars on the small belt, press “Start” step-by-step to test interval (adjust if needed).

Press “Reset,” switch to Auto Mode, and press “Start” to begin jar transport.

5. Alarm Handling: If the sensor detects over-limit jars, remove the jar, clear the alarm on the screen, and press “Start” again.

Pre-heating device

Structure

How to Operate

1. Bottom Heating Setup:

Unlock the electrical box, push up the electric brake, and turn on the power switch.

Use the button to set the target temperature (green number), then turn on the heater switch (green indicator = ready).

2. Body Heating Setup: Repeat the same steps for the body-heating box, then turn on the fan switch for temperature stability.

3. Integration: Ensure the pre-heating device runs 5–10 minutes before the filling machine, so jars are pre-warmed when they reach the filling nozzles.

Conclusion

Dongguan Yide’s Full-Auto Production Line redefines candle manufacturing by turning fragmented, labor-heavy processes into a seamless, efficient workflow. Its modular structure adapts to different jar sizes and production volumes, while precise controls (e.g., servo-driven pumps, customizable temperatures) ensure consistent quality. Whether you’re a mid-sized factory scaling up or a large brand aiming for mass production, this line cuts costs, reduces errors, and boosts output—all with user-friendly operation that minimizes training time.

For candle producers looking to stay ahead in a competitive market, investing in a full-auto line like Yide’s isn’t just a choice—it’s a strategic move to unlock scalability and reliability.
