Conveyor emergency stop safety control belt sway switch
The Belt Sway Switch functions in detecting any deviation or sway in the conveyor belt and providing an auto-alarm and sending out signal to stop the conveyor to avoid the damage to the conveyor belt and prevent scatter of conveyed materials because of the belt distortion. The Belt Sway Switch is necessary in the safe conveying system, widely used in the belt deviation detection of the belt conveyor for coal, cement and building materials, mining, electricity, port, metallurgy and chemical industries.
Its functions are in two levels: one for auto-alarm, the other for auto-stop. During the operation of the belt conveyor, when the belt sways and touches the vertical roll, the roll turns on its axis; when the belt sways abnormally, it will squeeze the vertical roll and make it offset. When the vertical roll is at 20 slant, the first level switch function may send the alarm signal. When it continues to be at 35 slant, the second level switch function works to send the stop signal. The first level signal functions to alarm the switch to adjust deviation automatically. The second level signal functions to stop the conveyor automatically. After the fault clearing, the belt departs from the vertical roll and operate normally, the roll may reset automatically.
Belt Sway Switch is constructed with high reliability microswitches, lubricateless ball bearings, a touch roller which is titled to 75 , and other parts; its functions are designed with a large margin for sure action and long life.

Installation:
|
1. Fix the BELT SWAY SWITCH in mounting bracket and located on both sides of conveyor belt. |
|
2. Select suitable mounting supports according to belt straight deviation, the angle is as same as belt dip angle. |
|
3. The angle of mounting support is as same as belt dip angle, and now the roller lever is vertical with belt surface |
