Some glass factory in shandong, feeding way USES the glass surface of vacuum suction feeding way, so that the glass liquid level fluctuation for the very strict, the feeding device for glass liquid surface fluctuation range in the + / - 0.3 mm.So you need to show us a adjustment scheme, to solve the YS type automatic coal feeder according to liquid level detector signal feeding, to furnace automatic cloth, and make sure the glass surface range control at + / - 0.3 mm, to ensure that the vacuum feeding feeding equipment can normal use.
Adjustment scheme of GLD series belt feeder:
Keep the feeding track and running mode of GLD series belt feeder.Coal feeder will be issued according to the laser liquid level meter of continuous feeding of analog signal, using continuous cloth, and used in the process of feeding of the sinusoidal oscillation mode of feeding speed, namely by adjusting the output, adjust the capacity is how much and how fast, to ensure that the liquid level within the required range.
Continuous feeding mode:
The continuous feeding signal (i.e., analog quantity signal) of the liquid level meter will be collected by the coal feeder. Through the PLC analog quantity acquisition module, it will be firstly converted to digital quantity, which will be used as the calculation basis for adjusting the feeding speed.PLC through the logic operation, two analog signal output, control to the coal body, coal feeder of the truss section keeps uniform movement of don't ask, don't break down the fixed cloth trajectory, continuous feeding don't ask, don't break the ground.
Feeding mode is variable speed feeding:
Coal feeding mechanism includes vibrator and belt conveyor.The control mode of belt conveyor and vibrator will be changed into the control mode which can be adjusted according to the simulated amount of white motion.The belt motor increases the frequency converter, and the vibrator increases the analog input control module.So the whole coal institutions will work on the basis of analogue adjusting control, in the process of the fabric, according to the output of glass material level meter analog signals of liquid level height, controlled by PLC analog output module output current, and vibrator working current of the belt can be adjusted, and the belt between the vibrator and the interlocking control, adjust the speed synchronization.The speed adjustment process of coal feeding mechanism is adjusted to ensure the uniformity and continuity of the cloth, and finally achieve the function of variable speed feeding of coal feeding mechanism.
Simply put, the working process is: the coal feeding frame part will keep constant speed, no matter break motion, along the fixed fabric track, uninterrupted continuous cloth.At the same time, the glass liquid level height signal feedback from the liquid level meter is monitored in real time, and different feeding speed is adopted according to different material liquid level height.When the liquid level rises gradually, the feeding mechanism will gradually slow down, and when the liquid level rises to the upper limit, the feeding mechanism will slow down to the lower limit.When the liquid level is zero, the feeding mechanism is maintained at normal speed.When the liquid level drops gradually, the coal feeding mechanism will speed up gradually. When the liquid level drops to the lower limit, the coal feeding mechanism will speed up to the upper limit.
