Analysis of the Cause of Plugging Material in Vibrating Feeder

 1, from the characteristics of the material itself, the main reason for the vibration feeder to block the viscosity and moisture larger. Due to the lower material flow, this will result in the usual "hanging wall" and "shedding" phenomenon after entering the warehouse, especially during the rainy season.

 
2, Vibrating Feeder Corresponding Vibrating Feeder During the shutdown of the transport system, due to the long storage time in the vault and the influence of humidity, the friction between the material and the wharf increases, resulting in blockage.
 
3, silo memory material is too small. Because the material is falling from a dozen meters height, the deeper the vibration feeder hopper depth, the greater the acceleration, followed by the impact of the larger, so a certain degree of material under the action of gravity, and gradually to the bottom of the silo Material impact compaction; When re-discharge, it is likely to block.
 
4, structural block warehouse. At present, the vibrating feeder hopper is made of steel plate, most of its shape is the cone, square cone or hyperbolic shape with a large mouth opening and a small mouth opening. Material in the warehouse by weight from top to bottom flow, the lower the cross-section of circulation is smaller, which is an important reason for the occurrence of congestion.
 
5, poor material storage point management, leading to large pieces of material or foreign material warehousing. Vibrating feeder hopper entrance, not set according to the requirements of sieve Gates mouth is too large, resulting in large pieces of material or foreign matter into the warehouse, resulting in blockage.

6. In the process of using, we should also be careful not to press the load of the silo directly on the chute of the feeder, which will lead to fatigue damage of the spring plate and the connecting fork for a long time, resulting in the rupture of one of them.
 
7, may be too much feed, resulting in the accumulation of material in the base, lifting resistance screw conveyor increases, the hopper caused by poor operation, in which case should be less incoming and keep the amount Feed evenly.
 
8, feeder gap between the iron core and the armature caused by too much or too small. If this happens, the feeding of the feeder will be affected because the machine can not reach its normal amplitude.
 
9, may be due to the lack of coordination between the various parts of the feeder, these are mainly due to the loosening of some parts. This requires tuning of the components, adjusting the compaction of the machine spring plate compacting bolts to the optimum amplitude for the chute.
 
Although the vibrating feeder is only ancillary equipment, it plays an important role in the entire production line as a joint hub. Vibration feeder failure will not only affect the work efficiency, affect the service life of equipment, is likely to lead to the entire production line shutdown, resulting in huge economic losses. Routine maintenance, should always check the status of vibrating feeder equipment, regular inspection and maintenance, reduce equipment failure rate.
