Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to a load testing device for packaging machines. Background Art

[0002] A packaging machine is a device used to package products. Its structure includes a conveying system, a packaging material supply system, a sealing system, a control system, etc.

[0003] In the process of packaging raw materials in bulk, the load testing device of the traditional packaging machine needs to weigh the raw materials in bulk first, and then process the packaging materials into open packaging bags.

In this process, the weighing of the raw materials in bulk and the pre-processing of the packaging materials are not carried out synchronously, which wastes time. At the same time, the re-weighing is not carried out after the packaging is completed, which may easily cause damage to the transport vehicle due to overweight of the finished packaged product after packaging.
