Description

Technical Field

[0001] This patent application belongs to the technical field of sampling equipment, and more specifically, it relates to a sampling and cutting device for ton bags. Background Art

[0002] At present, in the metallurgical industry, bulk materials are generally transported and stored in ton bags. To ensure production quality, according to the requirements of quality management standards and specifications, it is necessary to conduct sampling tests on bulk materials. Often, one or more openings need to be made in the ton bags for sampling, and the accuracy of sampling is an important factor in production quality control.

[0003] At present, most steel companies use a utility knife to open the ton bags during the sampling process. Workers manually cut on the ton bags to create one or more openings on the surface of the ton bags for sampling. When using a utility knife blade to cut the ton bag, the operator needs to cut the same point multiple times. This cutting technology has the disadvantages of long operation time, high labor intensity of workers, frequent replacement of blades and utility knives, low work efficiency, and high cost. At the same time, during the cutting process, the utility knife will be affected by the unevenness of the internal materials, and the blade is prone to breakage and splashing, posing a safety hazard.
