Description

Bar metering scale of antimagnetic suction

Technical Field

The utility model belongs to the technical field of weighing apparatus, and relates to a metering device for realizing metering by using a magnetic crane for hoisting bundled bars in a bar production line in the metallurgical industry.

Background

After the bars produced by the bar production line of the steel plant are bundled and taken off line, each bundle is required to be weighed and measured independently due to the influence of other factors such as quality inspection sampling and the like. Because of the factors of reducing production equipment and field personnel, the magnetic force crane is adopted to transport and meter bundles of bars on site.

In this case, there is a metering challenge: when the bar is lifted by the magnetic crane and is close to the weighing scale above the weighing scale, and the bar is placed on the weighing scale, the weighing scale body of the weighing scale can be sucked or shifted by the large magnetic attraction force due to the action of the strong magnetic field of the magnetic crane, so that weighing data is misaligned. In view of the above, there is a need for an antimagnetic bar weighing scale that requires that the scale body is not lifted or displaced by the magnetic force when the bar is lifted onto the scale by the magnetic force, thereby ensuring the weighing performance of the scale. The bar material weighing scale with the antimagnetic attraction is designed according to the magnetic force requirement of the magnetic force crane on the production site, so that the operation requirement of the weighing scale is met, and the later maintenance and overhaul of the weighing scale are convenient.
