Structural composition:

1、 Weighing instrument

1. Comprehensive error of instrument:<0.02%

2. Sensor input port: 6 350 ohm sensors can be connected, and the sensor sensitivity is required to be above 1.5mv/v.

3. Weighing instrument: 32 bit ARM CPU is used for high reliability and fast operation.

4. Wide power supply design: 85V-260V 50HZ

5. 24 bit ADC sampling module, speed 240 times/second. Chinese and English menu display, 6 channels of switching value, 2 channels of analog input and 2 channels of analog output. Large LCD display. The standard RS485 interface (modbus protocol) can fully connect with DCS.

2、 Speed sensor or encoder

1. The pulse shaping circuit is added to the speed measuring input of the speed measuring sensor, which can make the speed measuring result more accurate and stable.

2. 8030-1024 photoelectric encoder φ The roller at the end of the axle hole is directly connected, with good concentricity and long service life. Strong anti-interference ability.

3、 Load cell

The weighing sensor with high sensitivity of more than 2mv and temperature compensation function shall be used to adapt to the environment of - 30 ° C - 60 ° C. No drift, stable operation, high accuracy.

4、 Excellent frequency converter 

It adopts foreign or domestic first-line brands, high-performance vector control technology, with wide speed range, accurate speed regulation and strong overload capacity, fully meeting the demand for quantitative batching control.

Scale body characteristics

1. Scale frame:

The scale body is made of 5mm cold-rolled plates, which are bent into a C-shaped frame structure at one time. It has high strength, stable structure and is not easy to deform.

2. Drive:

The transmission device (motor reducer) adopts SEW or SBD Schenck scale special reducer, which is installed in the shaft hole suspension direct connection mode, and the belt is driven directly by the driving roller (without vibration and smooth movement).

3. Guide and automatic deviation correction device:

During the belt operation, when the belt deviates to one side due to an external force, the deviation correction device of the scale body will automatically push the counterweight device through the connecting rod to force the belt to reset automatically by using the reverse force.

4. Automatic tension adjusting device:

djust the driven roll tension screw to adjust the tension of the belt of the scale body, keep the tension of the conveyor belt constant, and prevent the belt from deviation and slipping through the guide stop roll and automatic deviation correction device.

5. The driving roll and driven roll of the scale body adopt a unique waist drum structure to effectively prevent belt deviation. The driving roll and driven roll are coated with glue to effectively prevent the belt from slipping.

6. All bearings of the belt weigher are imported bearings, which are waterproof, firmly sealed and durable. Fully adapt to harsh environment and have a long service life.

7. The feed inlet is equipped with a material flow shaping ram to facilitate the adjustment of the material layer thickness.

8. Pear shaped sweeper and belt rubber scraper are set between the belt and the roller, which can remove the adhesive materials on the belt at any time to ensure the measurement accuracy and zero point stability of the scale body.

9. Both sides of the scale body are equipped with (emergency stop) switch devices to connect with the controller, which can realize on-site power-off and shutdown, and make maintenance safe and more convenient.
