The external structure is shown in Figures 1 and 2. 5、 Working principle: In the event of an emergency on the site of a tape conveyor, the steel wire rope attached to the hanging ear is pulled at any position along the line, forcing the internal cam of the machine to rotate and driving the microcomputer switch to act, issuing a shutdown signal to achieve the shutdown effect and prevent the accident from expanding. 6、 Installation and adjustment: This product is generally installed on two racks along the conveyor belt. Please refer to Figure 3 for details< 1. Fix the drawstring switch on the bracket< 2. The distance between the two machines is 25-30m, and a steel wire rope with a diameter of 4mm is used for connection. The tension should be moderate< In order to reduce the impact of the weight of the steel wire rope on the switch and prevent misoperation, a support ring is welded to the frame every 3 meters to support the steel wire rope and ensure its normal operation. 4、 Product features& The universal installation design allows the anti deviation switch to be installed freely on the top or bottom of the conveyor longitudinal beam< 2.

The cover plate can be removed without removing the lever< 5. The rated speed of the action rod bearing is 5000 revolutions per minute, suitable for belt speeds less than 6.35 meters per second< The normal angle adjustment range of the action lever is 22.5 degrees< When the normal angle is 10 degrees, the alarm contact will act, and when the normal angle is 20 degrees, the shutdown contact will act. Belt Switch, also known as Anti Bias Switch. It is a product used to detect the deviation of the conveyor belt of a belt conveyorA safety protection device that automatically alarms and stops the conveyor belt in case of deviation. Introduction: The deviation switch has two levels of angles. The commonly used ones are: the first level angle is 10, 12, and 20. The second level angle is 30, 35, and 45. The basic principle is that when the conveyor belt deviates during operation, the conveyor belt touches the switch vertical roller and causes it to deviate. When the deviation angle of the vertical roller reaches the first level switch angle, the switch sends an alarm signal. When the conveyor belt deviates seriously and reaches the second level switch angle, the switch sends a stop signal to automatically stop the conveyor belt due to deviation fault. When the deviation fault is eliminated and the tape machine is running normally, the switch vertical roller can automatically reset and return to the initial state. Installation and adjustment: 1. The deviation switch should be set on both sides of the conveyor belt, and the vertical rollers should be perpendicular to the edge plane of the conveyor belt, with both sides of the conveyor belt located at 1/3 of the height of the vertical rollers. The distance between the vertical roller of the deviation switch and the normal position of the conveyor belt should be 50-100mm. The number of deviation switches should be determined based on the length, type, and layout of the conveyor. Generally, it should be set at the head, tail, convex arc section, concave arc section, and in the middle position of the conveyor. (Note: When the conveyor is long, one pair can be installed every 30-35 meters in the middle position of the conveyor.) 4. The deviation switch should be connected to the middle frame of the conveyor through an installation bracket. The switch bracket should be welded to the conveyor frame after the conveyor is installed. The deviation switch and the deviation switch bracket should be fixed with bolts. Scope of application: Two level deviation switch for conventional belt conveyors: underground, cable support belt conveyors: ship loading and unloading systems; Stacking/reclaiming conveyor; Tilt and shuttle conveyors; Crane, excavator, boom limit: skirt feeder/conveyor: heavy-duty limit switch detects the deviation of the tape, which is a protective device for automatic alarm and shutdown of the tape machine control.
