Description

Technical Field

[0001] The utility model relates to the field of weighing and measurement, in particular to a lifting weighing device. Background Art

[0002] As a product of the development of modern sensor technology, weighing devices (especially electronic scales) have become an indispensable measuring tool in our lives and play an important role. In industrial production, electronic scales are used for weighing raw materials, semi-finished products and finished products, as well as for automatic batching on production lines. Their high precision and stability are of great significance for ensuring product quality and production efficiency. In order to improve the degree of automation of weighing, a weighing device is provided at the transmission and unloading port of the workpiece to be weighed, and the unloading and weighing are carried out directly; however, in most of the transmission and unloading processes, the workpiece supporting platform in the weighing device does not match the height position of the transmission and unloading port, which causes the workpiece to be weighed to be damaged during the falling process or causes inaccurate weighing measurement. Installing a lifting component at the lower end of the workpiece supporting platform is a solution to the above problems, but the lifting component is often prone to horizontal deviation during the up and down movement due to the large weight of the workpiece to be weighed, making it difficult to ensure that the workpiece supporting platform is in full contact with the weighing scale, thereby affecting the accuracy of weighing. Moreover, during weighing, the workpiece supporting platform is also easily disturbed by the contact support force of other components, and the accuracy of measurement cannot be guaranteed. In industrial production, inaccurate weight measurement is often fatal.

[0003] Therefore, how to design a lifting weighing device with high-precision measurement has become an urgent problem that technical personnel in this field need to solve. In order to solve this problem, this application proposes a lifting weighing device. Utility Model Content
