OVER HEAD BRIDGE OF 3/5/7 PRODUCTION LINE
3 Layer single over head bridge
- SINGLE layers are used in 3ply production lines.
- Strong ladder. Safe guardrail and the full strong patterns plate to make sure the safety of the workers on the over bridge.
- On the single facer have drop system, sole frequency motor device, with the corrugated machine's speed at the same step.
- It adopt cotton tape conveyer, strong friction force Better ventilation property
- The entire belt roll and the surface of the roll after grinding Processing and chrome plated.
- the bridge suction adopt adsorb tension single corrugated paper, and adjusting the blast
- volume to match the tension of different paper quality and speed.(can adopt frequency adjusting the blast volume)
- Vacuum absorption box can be adjusted according to the width of the paper.
- Baffle electric adjusting, correcting the error and adjusting multi-ply corrugated paper. (it can adopt PLC control baffle auto location suction)
- The over bridge and pasting machine are operated individually easy to operate.
- Suit the production line speed 100m/min
- Valid breadth: 1200/1400/1600/1800/2000/2200 mm.
5 Layer Duplex Overhead bridge
- Main frame are connected with channel steel, joist steel and angle steel
- Both side are equipped with safe guardrail and safe herringbone pedal, the operation plate is equipped with safe escalator to ensure the safety of worker and convenient operation
- Independent variable frequency motor lifting mechanism, PVC conveyer belt transmit, the single corrugated board from steady flute profiles.
- Surface of all rollers are grinding and plated chrome.
- Vacuum suction tension control, aspiration channel: 5inches, install regulation valve, the air volume can be adjusted stepless.
- One set of electromotion correction device, correction baffle adopt double guide post positioning , lead screw drive, fix position quickly and accurate, transmit steady.
- Electromotion control installing two group of operation plate, upper and lower bridge can be adjusted arbitrarily, it is convenient and quick
- With high strength composite board on the whole bridge, smooth and durable, small friction, reduce the resistance of paper board transmission.
- Working width: 1200/1400/1600/1800/2000/2200 mm
- Operation direction: left or right
- Height of top: 4700mm
- Design speed: 60/90/120/150m/min
