Industrial-grade automatic CAV fuel filter paper coiling machine designed for high-precision double-layer filter winding. Features an adjustable coiling speed, a 10 kg hot-melt tank capacity, and 50–130 mm coil diameters. To establish a complete automotive and industrial filtration manufacturing line, this liquid filter coiler is perfectly paired with our Semi-Automatic Honeycomb Air Filter Coiling Machine to handle both fuel and heavy-duty air filter core production.
This high-efficiency Automatic CAV Fuel Filter Paper Coiling Machine is specifically engineered for winding and shaping CAV-type fuel filter elements and automotive diesel filter cores. It integrates uncoiling, precise double-layer paper corrugation, hot-melt adhesive dispensing, and spiral rolling into a single continuous process. It is highly technical and suitable for shaping the coil paper of prominent filter elements, including Toyota-style fuel filters.
Equipped with an advanced three-stage counter, approach sensor switches, and independent temperature controllers for the glue nozzle and melter, this winding machine ensures that the paper core is rolled to the exact tightness and diameter required. By preventing glue leakage and wrapping the media tightly, it ensures the robust performance and high filtration efficiency of spin-on fuel filter cartridges.

Key Features & Mechanical Advantages
1. Synchronized Variable-Speed Coiling
The rolling speed of the spindle can be adjusted freely according to the current coil diameter. This variable-speed control ensures that the inner layers and outer layers of the double-layer fuel filter paper are wound with uniform, appropriate tightness, preventing center core collapsing.
2. Precise Multi-Stage Diameter Control
Utilizing a highly accurate three-stage electronic counter paired with magnetic approach switches, the machine automatically stops or triggers cutting once the exact preset outer diameter is achieved. This ensures highly uniform outer dimensions for easy metal housing insertion.
3. Advanced Hot-Melt Adhesive Management
The integrated 10 kg hot-melt unit features fast adhesive melting speeds and variable-frequency flow adjustment. Both the melting reservoir and the dispensing nozzle are independently temperature-controlled, preventing adhesive carbonization and guaranteeing smooth, uninterrupted glue lines.
4. Zero Glue Leakage Injection Cylinder
The injection cylinder is programmed directly via the PLC to precisely control glue dispensing at the left, right, or center of the paper tube. This targeted application guarantees that the rolled filter core ends remain clean, flat, and completely free from messy glue leakage.
