-LCXK-III instrument is used to measure and control measurement of feeding device computing systems.

The instrument applies to the following control system.

1. Dosing machine

By controlling the feeder belt speed, so as to control the feed traffic.

2. Belt-feeder belt scale

Adjust the belt load by pre-feeder control that can control the feed flow.

3. Belt scale

Through the belt speed and belt load, calculate the volume of traffic and feed.

 

Sketch of front panel:

 

Display:

16x16 dot-matrix LCD backlit, 2 line, the character is 6mm.

Up left of the monitor: running information

Right: setting the feeding unit is t/h

Down left of the monitor: event information

Right: you can select for the actual flow, belt speed, belt load and other

If the LCD screen is not clear, the potentiometer can adjust the LCD Panel on the left corner.

 

Lights:

2 LED lights green and the 3 red LED lights.

Green light: operation ready

Red eye: faulty or limit value out of information.

 

Keyboard:

Flexible films can touch the keyboard.

Key notes:

 

 

Display parameter definitions:

 

Flow = feed rate unit of actual value: t/h

--Amount of material in unit time through a belt.

Setting = feed rate setting unit: t/h

--According to the set value to control the actual value.

Trojan = cumulant units: t

--Cumulant x feed = feed rate

Speed = speed of conveyor belt unit: m/s

Load = belt load unit: kg/m

Coincident code number = load sensor signal conversion code-bearing units: none

Temperature = instrument internal temperature units: ° c

 

Instrument the way you work:

Weight: control.

Volume: uncontrolled way.

Note: uplink displays to the left of the monitor "▲" indicates volume work, "" display, indicates that the weight is the way you work. If no show, the instrument is working in a controlled way.

 

Second, the working principle and structure

 

1. working principle

 

Feeding machine working principle

 

(1) measurement of conveyor belt weighing system on the volume of transported materials.

(2) control a control loop belt speed, so as to control feeding amount.

Feeding size depends on the amount of:

① materials on the belt's height, width and density of the material.

② the belt speed.

 

Control principle:

Q is the pre-belt load feeders (feeding Hopper, pneumatic feeder, vibrating feeder, etc) given, feeding volume is controlled by the belt speed.
