我厂球磨机给矿用500皮带运输机,由于张紧力变化比较大,影响皮带秤的计量精度。影响张紧力的原因在于,设备运行中皮带跑偏,或运行一段时间后由于张紧力不够等原因,都要调整皮带机的固定拉紧装置。另外,首尾轮、托轮沾结矿泥等也会影响皮带张紧力,使皮带秤的零点偏移,秤的计量不准确。基于上述原因,我们设计了一个尾轮拉紧力恒定的自动调整装置。该装置是把原来左右 I mill conveyor to the mine with 500 belt conveyor, due to larger changes in tension, the impact of the belt scale measurement accuracy. Tension due to the impact of the reason that the equipment running belt deviation, or run for a period of time due to lack of tension and other reasons, must adjust the belt tensioning device fixed. In addition, the first round of wheel, roller bearing mud and other knot will also affect the belt tension, the belt scale zero offset, scale measurement inaccurate. For the above reasons, we have designed a self-adjusting device with constant tail tension. The device is turning the original around
