Buffer type weighing sensor module

Abstract

The invention discloses a buffer type weighing sensor module, comprising a weighing sensor, a sensor pressure head and a buffer device, wherein the sensor pressure head is arranged on the weighing sensor. The buffer type weighing sensor module is characterized in that a buffer mechanism is arranged on the sensor pressure head, the buffer mechanism comprises an upper base plate, a disc spring set and a lower base plate positioned on the sensor pressure head, and the disc spring set is positioned between the upper base plate and the lower base plate, a limiting mechanism is arranged between the upper base plate and the lower base plate. The buffer type weighing sensor module has the advantages that the field application performance of the wide-range structure weighing sensor in large-load and high impact occasions is improved, the problem that the service life and the accuracy of the weighing sensor are influenced by the high impact load is also solved; and the buffer type weighing sensor module adopts a novel weighing sensor installation module structure and has significant effect on weighing systems adopting traveling cranes to place material to be weighed in the metallurgy, harbor and large material weighing fields.

Description

technical field [0001] The invention relates to a load cell, in particular to a buffer type load cell module. Background technique [0002] At present, there is no perfect buffer structure in the field of weighing sensors and weighing systems. In the past, the more mature application at home and abroad is to adopt a split buffer structure in the scale body of the weighing system, and use the double weighing platform structure to achieve large-scale materials. The core of the buffer is to use the space between the upper weighing platform and the lower weighing platform to add a buffer spring. The biggest disadvantage of this structure is that the structure of the scale body is complicated, the weight of the body is too heavy, and the amount of steel is greatly increased, especially for special occasions. It is inconvenient, and this structure also seriously affects the comprehensive accuracy of the entire weighing system and the service life of the sensor. Contents of the i...
