Abstract
The utility model discloses a high-pressure suction ventilator constant pressure control system. The high-pressure suction ventilator constant pressure control system comprises a man-machine operating interface, a signal collection unit, a signal conversion unit, a signal processing unit and a frequency transformer. The man-machine operating interface comprises an input keyboard and a displayer. The input keyboard is used for inputting air suction pressure parameters. The signal collection unit is installed at the air suction port position of a high-pressure suction ventilator and used for collecting pressure signals of the high-pressure suction ventilator. The signal conversion unit converts the pressure signals into electrical signals and transmits the electrical signals into the signal processing unit. The signal processing unit obtains a control signal after comparing the electrical signals with the air suction pressure parameters input on the man-machine operating interface and transmits the control signal to the frequency transformer. The frequency transformer adjusts rotating speeds of a motor of the high-pressure suction ventilator according to the control signal. The purposes of adjusting air suction pressure according to corrugated boards with different gram weights and reducing heat energy loss and electric energy loss are achieved.
Description
Technical field
The utility model relates to corrugated board manufacturing technology field, particularly a kind of high pressure induced-draught fan control system of invariable pressure.
Background technology
The outer-cover type vacuum suction by suspended hood, lead paper copper sheet, aspiration channel, air door, high pressure induced-draught fan and silencer and form.Be evenly distributed with the air draught groove on the lower corrugated roller roll surface of outer-cover type vacuum suction, the high pressure induced-draught fan is through the strong exhausting of aspiration channel, make between suspended hood inner chamber and the lower corrugated roller and form negative pressure, by the air draught groove on the lower corrugated roller corrugated paper after the moulding is close on the lower corrugated roller, finish exactly the gluing compound working procedure, lead the paper copper sheet by being installed on the suspended hood and stretching in the air draught groove of lower corrugated roller again, two layers of corrugated board that composite drying is good from the lower corrugated roller guiding out, air door can be regulated the control suction air volume during this time, and silencer reduces the noise of air draught air-flow.Change the Corrugator roller of different stupefied types, can produce two layers of corrugated board of various stupefied types.The outer-cover type vacuum suction has been eliminated and has been led pawl formula structure because of the location wild effect that mechanical wear causes owing to the corrugated paper that adopts after the negative pressure of vacuum principle is come positioning molding, is enough to adapt to run up.Especially minitype corrugation cardboard, the corrugated paper intensity after the moulding is low, yielding, should not locate, and the whole world only adopts the mode of vacuum suction or air cushion malleation to adapt to run up at present.
Since the strong exhausting of high pressure induced-draught fan, the continuous conversion of height grammes per square metre, and air quantity is regulated and can't in time be adjusted, often in process of production air quantity is adjusted to maximum, cause corrugated paper in the wind groove, to cave in, cause the corrugated board physical property to reduce, cause simultaneously heat energy excessively lost, the electric power significant wastage.
