How to deal withHigh-position palletizerWhat about the conveyor belt deviation at work?
When the conveyor belt deviates from the track, the conveyor belt pushes the vertical tapered roller to deflect the fork fixed on the tapered roller by an angle. The movement drives the end block of the opposite roller of the cross pin, and the side roller brakes. The sliding friction between the conveyor belt and the roller group causes the roller group to rotate an angle around the vertical axis, so that the conveyor belt moves to the center.
The structure of the new powerful centering roller group is similar to the traditional product, retaining the original rotating mechanism and main beam. The rollers are changed to several sections, and the vertical rollers on both sides are changed to tapered rollers. At the same time, the forks for fixing the tapered rollers, the blocks supporting the end faces of the rollers and the horizontal pins under the tapered rollers are added.
The existing roller structure is composed of a cylinder, a washer, a bearing seat, a main shaft, a bearing, and inner and outer seal rings. The number is large, and the reliability of the connection between the bearing seat and the pipe body is poor. To this end, a new type of roller can take the form of a counter-rotating coil spring, and its structure is composed of a bearing seat, a counter-rotating spring fixed on the bearing seat, a bearing, a mandrel with a hook head, a sealing ring, a retaining ring, etc.
The unevenness of the material falling on the conveyor belt can easily cause the deviation of the conveyor belt. Therefore, it is necessary to adjust the blanking point of the central blanking hopper to improve the deviation caused by the incorrect blanking point. Therefore, the baffles on both sides of the loading trough can be swung, and the position of the blanking point can be adjusted by adjusting the screw. When the conveyor belt is running normally, the vertical roller is not pushed by the conveyor belt.
Under the action of the spring, the vertical roller is reset and the opposite roller is automatically released. This new type of strong reversible automatic self-aligning roller set overcomes the traditional problems of small centering torque and unsatisfactory centering effect. The centering effect is good, the structure is simple, and the maintenance is convenient.
