Belt Sway Switch is applied to the belt conveyor. During the operation of belt conveyor, the belt center line is separated from the belt machine center line, and this phenomenon of deviation to a side is called run-off. If the belt is in a run-off state, there will be a strong friction between the conveyor frame and the belt edge, so that damage the belt edge and even shorten the machine life. When it is in serious run-off situation, the belt will fall down from the machine, and cause a serious accident. So, when install the belt conveyor machine, adjustment, operation and maintenance of the belt conveyor, special attention should be paid to the running state of the belt to prevent the belt conveyor from causing the accident. The belt sway switch is also called the polar belt sway switch. In the operation of the belt conveyor, the belt run-off and contacts with the vertical roll of the belt sway switch, the vertical roll rotates, and if the running deviation continues to increase, the extruding vertical roll will shift. When the roll deflection angle exceeds 20 °, the primary switch begin working, and sent alarm signal. When the roll deflection angle is more than 35 °, the two-stage switch action, cause stop signal. The primary switch signal is used for alarm. If this signal is connected with the running adjustment device, the automatic adjustment of the running deviation can be realized under the condition of working machine. The secondary switch signal is used to stop and connect the signal to the control circuit, which can realize the automatic shutdown under the condition of serious run-off. After faults remove, the vertical roll of the belt sway switch can be reset automatically when the belt is running normally away from the vertical roller. EXCT belt sway switch protection standard up to ip67, can completely prevent dust entry and water erosion. The maximum inclination is as high as 75 °and the degree of freedom is higher. Our belt sway switch adopts the international leading double-bearing transmission structure to avoid the direct friction shell or the shaft sleeve of the transmission shaft when the switch is operated, so that the gap is increased, the sealing is not tight or stuck, and the service life of the belt sway switch is greatly prolonged; The belt sway switch adopts die-casting aluminum, the surface shot-blasting treatment with the independent operation, so that the operation angle of the switch can be adjusted according to the actual demand, and the surface of the shell can be painted, and it is not easy to fall off and has no peculiar smell and the other bad smell. The belt sway switch has abundant design and the quality has reached the international leading level.

The belt sway switch is a new generation of products developed by the scientific researchers of our company. It can be used to detect the deviation of belt conveyor and prevent the material overflow caused by the deviation of belt. The belt sway switch is an indispensable sensor element for automatic control of conveyor. This product is widely used in conveyor belt because of its convenient installation and reliable switch performance.
