The seven - wheel double - layer water - cooled sheet extruder is a device used for cooling and shaping sheets of materials such as rubber and plastic after extrusion molding. Through its unique seven - wheel double - layer structure with cold water circulation for cooling, it efficiently cools the high - temperature extruded sheets, enabling them to quickly reach an appropriate hardness and shape. It is widely applied in the rubber and plastic processing industry.

The double - layer seven - wheel design increases the cooling contact area, improving the cooling efficiency by more than 30%. Equipped with a cold water circulation system, the temperature can be adjusted within the range of 5 - 25℃, allowing the sheets to cool down rapidly, with a cooling rate of 10 - 20℃ per minute.

The spacing between the seven wheels can be precisely adjusted, and the sheet thickness control accuracy can reach ±0.1mm, meeting the production requirements for sheets of different thicknesses.

The rollers are made of high - quality steel, which is wear - resistant and has high concentricity. The equipment operates stably, with a speed of 5 - 20m/min, effectively ensuring continuous production.

Total power: 10 - 30kW; Power supply: 380V; Overall dimensions (length × width × height) of the equipment: approximately 5000×2000×2500mm.

Roller diameter: 300 - 500mm; Roller length: 1000 - 2000mm, suitable for sheets of different widths.

Cold water flow rate: 10 - 30m³/h; Cooling water tank volume: 500 - 1000L.

Cooling and shaping of rubber sheets, such as rubber sheets for automobile tires and rubber gaskets; Cooling and shaping of plastic sheets, such as PVC sheets and PP sheets.
