At present, the lead plaster conveying and batching mode mainly comprises the following steps:
the method is to feed a material belt below a material feeding bin, and realize quantitative feeding by controlling the speed of the belt and the feeding thickness of the belt. When lead plaster water is too large or the lead plaster is blocked due to agglomeration, the materials in the storage bin can not fall onto the belt; some of the bin wall vibrators are added, but the more the bin wall vibrators vibrate, the tighter the bin wall vibrators are, so that the lead plaster in the bin is bonded; and a mechanical push rod is added at the feed opening, so that the belt or the push rod can be damaged when the caking occurs. Therefore, the method has high discharging failure rate and can not ensure normal quantitative feeding.
Vibrating feeder, main regulation feed speed through control vibrating motor rotational speed, nevertheless lead plaster reduces in the hopper, discharge rate increase, and feed speed is unstable to once advance lead plaster when too much or caking when the feed bin, will amass can not the ejection of compact, the degree of difficulty of the even feeding of control is great.
The disc feeder is mainly characterized in that materials are uniformly distributed on a disc and then are eccentrically extruded to discharge, feeding is uniform, the thickness of the fabric is mechanically adjusted, and the feeding speed is controlled.
