Product Details
Working Principle
1.After the automatic filling system starts, empty bottles are transported to the filling station and detected by photoelectric sensors. Once the preset number of bottles is reached, the bottle blocking system positions the containers accurately. The filling nozzles then descend and begin filling automatically. After filling is completed, the nozzles rise, the bottle blockers release, and the filled bottles move to the next station. The system continuously repeats this process to ensure stable, efficient, and reliable operation. For higher accuracy requirements, a secondary filling function can also be configured.
2.During operation, the liquid level sensor continuously monitors the product level inside the storage tank. The PLC automatically controls the liquid supply system to maintain a stable liquid level, ensuring consistent and accurate filling performance throughout production.
FAQ about 2 Nozzle Filling Machine
Material Leaking from the Rear of the Cylinder (Piston Rod Area) — How to Fix It?
This is a common issue in double-head piston filling machines and is usually caused by the following reasons:
1.Worn piston seals:
Damaged or worn sealing rings can cause product leakage between the piston and cylinder wall, allowing material to flow to the rear side of the cylinder.
Solution:Remove the piston and replace the sealing rings.
2.Loose connection between the piston and piston rod:
If the piston is not securely fixed to the piston rod, leakage may occur during operation.
Solution: Check and tighten the piston connection.
3.Cylinder misalignment:
If the product cylinder is not properly centered on the support frame, sealing performance may be affected.
Solution: Reinstall and align the cylinder correctly.
Why Does the Filling Nozzle Keep Dripping After Filling?
Nozzle dripping is one of the most common filling machine issues. Below are the main causes and solutions:
1. Worn sealing components:
The sealing ring or gasket inside the nozzle may be worn and unable to close tightly.
Solution: Replace the damaged seals.
2. Incorrect nozzle closing timing:
If the nozzle closing delay is set too late, residual product may continue dripping.
Solution: Adjust the nozzle closing delay parameter in the control system.
3. Residual product remaining at the nozzle tip:
Viscous products may stick to the nozzle outlet after filling.
Solution: Use a filling machine equipped with a suck-back function, which pulls residual product back into the nozzle after filling.
4. Worn or damaged nozzle opening:
A nozzle opening larger than 7.5 mm or an uneven sealing surface can prevent proper shutoff.
Solution: Repair or replace the nozzle and polish the sealing surface if necessary.
5. Use anti-drip nozzles:
For oily or high-viscosity products, anti-drip or shut-off nozzles are highly recommended to minimize leakage and improve filling cleanliness.
