Tianfu hotsales’ Online Glue and Material Supply System is an active, automated network designed to keep the application point (the "point of use") constantly fed with adhesive or material.
It ensures that the machine never stops due to "starvation" (running out of glue) and that the material properties (viscosity, temperature) remain consistent from the first unit to the last.
Here is the technical breakdown.
🌐 System Overview: The "Heart and Arteries"
The primary function of this system is logistics and stability. It takes bulk material from a central source (drums, totes, or large tanks) and delivers it to the machine on demand.
Key Objectives:
- Zero Downtime: Automatic switching or refilling so the production line never stops.
- Consistent Viscosity: Maintaining the exact temperature throughout the entire pipe network.
- Precision: Delivering the material at a steady pressure to the dispensing valve.
⚙️ Key Components
- Drum Unloaders / Tote Tippers: For large volume systems, this mechanism lifts and inverts 200L drums or 1000L totes to feed the system.
- Day Tanks: A smaller "buffer" tank located near the machine. The main system fills this tank, and the machine draws from it.
- Positive Displacement Pumps: Gear pumps or lobe pumps are used because they can handle high-viscosity fluids and provide a consistent flow rate regardless of pressure changes.
- Recirculation Loop: This is critical. The system constantly pumps material in a loop back to the tank. This prevents the glue from stagnating, cooling down, or curing inside the pipes.
- Jacketed Piping: The pipes are not just empty tubes; they have a heating jacket (electric or oil) surrounding them.
- Trace Heating: Electrical heating elements run along the length of the hose to ensure the glue stays molten from the tank to the nozzle.
- Insulation: An outer layer protects operators from burns and saves energy.
- In-line Filters: Removes any particulate matter or "skin" from the glue to prevent nozzle clogging.
- Pressure Regulators: Ensures the glue arrives at the applicator at a steady pressure (e.g., 2-4 Bar), preventing "spitting" or uneven bead sizes.
