Background

The manufacturing equipment of spinning at present includes the storage tank (as shown in fig. 1) that is used for holding the spinning section, and the top of storage tank is equipped with the feed inlet, and the bottom of storage tank is equipped with the discharge gate, installs high material level appearance and low material level appearance on the lateral wall of storage tank. The spinning slices are transferred into the storage tank through the compressed air automatic control conveying device, and the pipeline is sealed in the whole process in the conveying process. Because pipeline length is longer, and has certain slope and height, still install more pneumatic type solenoid valve on the pipeline simultaneously, mechanical failure, electrical fault and gas source trouble often take place to lead to the feed inlet of storage tank to appear not feeding the phenomenon. If a fault occurs, the spinning slices in the storage tank are still in a discharging state, when the material level of the spinning slices is lower than the low material level, the low material level instrument gives an alarm, an operator finds and informs an electric instrument department, the electric instrument department arrives at the site to check and remove the fault, the series of operations need to take a long time, and the phenomenon of material breaking in spinning production is likely to occur in the overhauling process, so that the quality and the yield of spinning are reduced.
