In the stamping process, after the coil is unwound on the heavy material rack, it is fed into the leveling machine (or feeder). During the operation, the material rack unwinding speed and the subsequent leveling speed are often (or feeding). The machine feed speed is not synchronized.

At this time, it is necessary to install a frequency converter on the Ruihui standard heavy-duty material frame, and manually adjust the frequency of the frequency converter to control the fast, slow and stop motion of the material frame motor to achieve the purpose of synchronization with the feeder.

It is only installed on the Ruihui standard heavy-duty material rack, not only the manual manual adjustment of the inverter, but also the heavy-duty material frame motor to be controlled frequently, which affects the life of the motor and electrical parts, and the power consumption is also And increase.

When the light control induction device of Ruihui light-controlled heavy-duty material frame replaces the induction rod (frame) induction mode, it can automatically cooperate with the frequency converter to control the material frame unwinding according to the speed of the actual subsequent leveling machine (or feeder). The speed is fast and slow, and the effect of synchronization with the operation of the leveler is achieved.

The light-control type heavy-duty material frame unwinding speed does not need to be manually adjusted, and it is not necessary to start and stop in real time, which truly realizes the purpose of automatic speed control and stable unwinding.

The light control induction device of Ruihui Heavy Material Frame consists of photoelectric detector and photoelectric receiver.

The photoelectric detecting head is installed at the front end of the leveling machine, and emits light therefrom. The photoelectric receiver is mounted on the side of the rack, and receives light therefrom, and the two forms a safety light curtain, which is controlled by the frequency converter on the side of the material rack. Slow and stop action.

Ruihui light-controlled heavy-duty material frame control principle: When the material frame runs too fast, the sag of the material roll becomes larger, blocking the light emitted by the photoelectric detecting head, and the photoelectric receiver has no signal.

When the material rack runs too slowly, the sag of the tape becomes smaller, and the light emitted by the photodetector is received by the photoreceiver, and the photoreceiver sends the received light signal to the inverter.

The inverter controller controls the power supply frequency of the rack motor, and adjusts the speed of the material rack motor to be fast and slow, so as to synchronize with the speed of the leveler.
