It is necessary to know the working principle of belt sway switch if you want to maintain the belt sway switch normally and effectively. Belt sway switch is mainly to check the belt deviation of a device in the actual operation of belt conveyor, conveyor belt position is higher than the specified range, can be controlled by belt sway switch, can also be in an emergency on the belt conveyor to stop. When the conveyor belt equipment is in operation, there are overload, center of gravity deviation or conveyor belt distortion, etc., which cause the conveyor belt to deviate from the normal track, the conveyor belt squeezes the rotary arm, drives the precision CAM and touches the micro switch to send out an alarm and stop signal. The product is an indispensable sensor element for automatic control of conveyor, which can be used for belt deviation detection of conveyor to prevent material overflow and other faults caused by belt deviation. There is a two-color indicator light, which is green when the equipment is normal and red when the equipment fails. And it is especially suitable for the place with bad production environment.
Aluminum die-cast shell for belt sway switch has the advantages of waterproof, dustproof, shockproof, etc., convenient installation, reliable switch performance and long service life, and has been widely used in conveyor belt. The alarm signal of the first stage deviation can be connected to the automatic adjustment device to correct the deviation and distortion of the belt. The second level belt sway does the stop signal and connects it to the control line to realize the stop. The routine maintenance of belt sway switch are as follows: 1. The roller of the joystick of belt sway switch should be installed close to the edge of the belt, and should not be extruded or left too far away for emergency stop or alarm output of the equipment. 2. When a large amount of dust is attached to the periphery of the joystick roller, it shall be removed in time. 3. Observe the wear of the roller at any time. If the roller wear is confirmed to be more than 2mm, replace it according to the operation instructions of the equipment.Lock the nut after replacing the roller wheel. Operate the swing roller to confirm whether the belt sway switch works normally. If you need to test or replace wiring, adjustment and other reasons to open the outer box, be sure to pay attention to the completion of the operation of the outer box with locking screws, so as to avoid water and dust, causing accidents. 4. Cultivate the professional and safety maintenance awareness of field operators, people-oriented, machine-assisted, quickly and safely improve the working efficiency of belt conveyor.and ensure that operators safety.

Belt sway switch is the main switch on the belt conveyor and an indispensable sensing element. It affects the work efficiency of the production line and the personal safety of relevant operators. Therefore, users need to pay more attention in the selection of switches and installation, scientific selection, installation and maintenance is to ensure its safe use of the basis. The belt sway switch of Henan Excellent Machinery Co., Ltd can provide customers with accurate selection and subsequent maintenance. To achieve the ideal configuration of belt conveyor switch and high efficiency, sensitive reaction force, effectively ensure the safety of the production line and the safety of operators. Our company's belt sway switch is well protected in these aspects. It adds special wear-resistant steel to the joystick roller wheel, which is not easy to wear out in the friction with the belt.
