On-site maintenance of electronic belt scale

1. Transmission belt offset and treatment

The transmission belt offset is the situation where the axis of the buffer roller deviates from the axis of the conveyor during full load operation or weighing process. It is alsoElectronic belt scaleThis unavoidable situation is mainly caused by the following reasons:

The connector has a relatively large added value of net weight and attraction interference to the load cell. Therefore, vulcanized connectors are usually used, and mechanical equipment connectors are not allowed. .At the same time, it is necessary to ensure that the length error of the two side loops of the conveyor belt is no more than ten millimeters, and the total width error is 0.5% of the standard scale.\u003C\/b>

When the buffer roller deviates, move the roller there towards the forward angle of the buffer roller.\u003C\/b>

This is also caused by the material powder. Care should be taken to avoid this situation and clean it frequently.\u003C\/b>

This situation is usually caused by a large initial support force, so adjust it as much as possible.\u003C\/b>

3. The transmission belt is very likely and its treatment

The conveyor belt operates by the friction between it and the roller. If the friction is insufficient, it is likely to slip or not rotate. The transmission belt is likely to cause speed errors, and the materials on the transmission belt must be weighed repeatedly. In order to prevent the transmission belt from being damaged If possible, it is necessary to increase the friction between the transmission belt and the roller. The amount of friction between the two is positively related to the friction resistance, contact area and the positive pressure between the two. To increase the friction, we need to start from these aspects: Expand To determine the positive pressure between the drum and the transport force, the electronic belt scale needs to use a tensioning device, which can limit the weight of each support space of the conveyor belt so that it has flexible support to ensure that it is not possible.

Generally, smooth rollers can be used when the power is not large and the environmental humidity is low. In situations where the environment is humid and the power is high, rubber-surface rollers should be used to improve Friction.
