Weighing module

Abstract

The invention relates to a weighing module, comprising connecting module, upper bearing part, column weighing sensor, lower bearing part and bottom plate. The connecting module comprises top plate, support plate and fixing plate. The upper bearing part and the lower bearing part are installed on the top plate and the bottom plate respectively. The upper neck part of column weighing sensor is clamped on the upper bearing part. Upper and lower end faces of column weighing sensor are contacted with hole bottom spherical faces of upper and lower bearing parts. Screw bars of two anti-overturn bolts with shaft sleeves passes through fixing plate and rotates into two screw holes. Two ends of shaft sleeves are set against shaft shoulders of bottom plate and anti-overturn bolts respectively. The distance b is set between the bottom of fixing plate or support plate and the distance a is set between the shoulder of anti-overturn bolt and the fixing plate. The weighing module integrates weighing, vertical protection limitation and vertical protection together. It is provided with high weighing accuracy, convenient installation and maintenance, stable work and reliability.

Description

technical field [0001] The invention relates to a weighing device in an electronic weighing system, in particular to a weighing module. Background technique [0002] In cement, metallurgy, chemical industry, grain processing, petrochemical and other industries, when the weighing method is used to measure or control the material level of the material, multiple weighing sensors are installed at the bottom of the material tank to automatically measure the material in the material tank. weight or level. As disclosed in CN273644Y, the "Load Cell Module" consists of an upper fixed plate, a lower fixed plate, a sensor assembly between the upper fixed piece and the lower fixed plate, a support rod, and a fastening rod assembly. There are at least 4 limit holes, and a fastening rod perpendicular to the upper and lower fixing plates is provided between the lower fixing plate and the fixing rod, and the upper end of the fixing rod is matched with the upper fixing plate through a faste...

AI Technical Summary

Problems solved by technology

However, since the limit rod is connected to the bottom plate from the upper part of the top plate, it is a long bolt structure. When the tank is subjected to external force, because the tank will move horizontally or overturn, the bolt is longer and will be subject to greater tension and bending moment. , so it is easy to damage the bolts and lose the anti-dumping function

On the other hand, the component is installed on the material tank, so it moves together with the material tank, which brings inconvenience to maintenance
