    The Vacuum Ring Line is used for auto glass windshields pre-heater and pre-pressure, It’s composed of six main sections, Transfer System, External Thermal Framework, Heating Circulating Air System, Cooling Circulating Air System, Vacuum System and Control System.

    • The transfer system adopts the the chain drive.
    • Vacuum system, the vacuum pressure can be -0.08 to -0.1 bar.
    • Ensuring vacuum pressure of every part of the whole line will be over -0.08 bar in the process of running.
    • Equipped with heating system to ensure the transparency of laminated glass and PVB after initial pressure to arrive above 70%. (the highest temperature can be 130℃)
    • The glass will be discharged after cooling, and the temperature is less than 50℃.
    • In order to avoid unnecessary heating, VPL line must be equipped with suspended heating device (temperature arises to 90℃ )
    • The temperature error between actual temperature and stetted temperature shall not be over ±5℃
    • The running of the machine adopts indirect operate, including the manual control and automatic control, automatic cycle time will be 35-55 s, the manual control is operated by the ring system operators, loading one piece glass, touch the button once.
    • There is a sensor at the exist part, when the glass coming and touch it, the transfer will stop to prevent the operators do not unloading in time, and the glass fell to the ground.
    • Emergency stop button at the exist part.

    PLC touch screen control, with the alarm system, the working parameters will be auto-saved.

    Transfer System:

    • The transfer main frame part adopts Q235-A square tube welding
    • Glass studdle adopts stainless steel, the top spacer sleeve PVC molding.
    • The transfer transverse studdle tap position, adopts stainless steel.
    • Speed: 0.5-1.3 m/min,
    • Distance between two back baffle rods:300 mm
    • Distance between glasses (Rod distance): 127 mm

    Vacuum System:

    • Vacuum pump: Leybold, Germany
    • Max.negative pressure: 0.1 MPa
    • Independent air collector
    • Vacuum tap installed on the transfer line, tap for copper connectors
