1. Product details

JGC-40 type weighing belt feeder is a feed measuring equipment integrating belt feeder, electronic belt scale, frequency conversion electronic control, widely used in metallurgy, electric power, coking, chemical industry, building materials, wharf and other industries.

2. working principle

When the material passes through, the force transfer mechanism acts on the weighing sensor, generating a voltage signal proportional to the belt load into the integrator: at the same time, the integrator accepts the pulse signal generated by the speed sensor proportional to the belt speed, and obtains the instantaneous flow and cumulative flow of the material by integrating the weight signal and the speed signal.

3.System characteristics

Weighing sensor adopts double seal, long life and good stability;

The speed signal adopts photoelectric encoder, the speed signal is accurate and reliable, and the anti-interference ability is strong.

Unique anti-deviation technology to ensure the normal operation of the belt;

With automatic zero adjustment, automatic interval adjustment, automatic fault diagnosis function;

Open loop or closed loop control is optional, which can realize the single loop intelligent control of the system.

Optional various alarm devices, such as material blocking, material cutting, belt deviation, etc., can be timely in the control room to understand the scene situation;

Optional instrument interface :RS232 or RS485 interface and printer interface;

This equipment can be used as the basic unit of batching system.
