In the process of parking, the phenomenon of illegal car closing still exists in an individual team, namely, the car is directly closed to filter dust for parking, or the phenomenon that the air pipe is blocked due to too early dust filtering is stopped, the brush roller is twisted, the cover plate is twisted, the quality is influenced, and the phenomena of bad cars and fire alarm hidden dangers are caused in serious conditions.
When the car owner of value does to change shifts, clear yard work, still think back this parking stall and close the cylinder and strain the dirt, waste time promptly, influence work efficiency, increased certain work load moreover.
The carding machine is stopped for about 30 minutes from the time of stopping the cylinder to the time of stopping the cylinder, the cylinder under the same dust filtering unit is stopped for more than one hour, and the dust filtering unit is operated at full load in the period of time, so that the electricity consumption is wasted.
When the dust filtering is abnormal, such as blockage and twisting, the negative pressure of the carding machine is influenced, and partial machines far away from the dust filtering can stop due to insufficient negative pressure.
