Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fiber paper tube production, and in particular relates to a device for testing the tensile properties of paper used in chemical fiber paper tubes. Background Art

[0002] Chemical fiber paper tubes are paper tubes used for chemical fiber spinning, stretching and other winding. In the production process of chemical fiber paper tubes, single-layer paper needs to be unwound, and then multiple layers of paper need to be compounded with glue to form multiple layers of paper for winding to obtain paper tubes, and finally cut into small sections of chemical fiber paper tubes. In order to improve production efficiency, the unwinding and compounding processes of paper are carried out using automated equipment. During the production process, conveyor rollers are required to convey paper. When the conveyor roller acts on the paper, it will exert a certain pulling force on the paper. Single-layer paper has weak tensile strength and is prone to breakage. Once a break occurs, the machine needs to be shut down for cleaning and maintenance, which will waste a lot of paper and affect production efficiency. Therefore, the purchased paper rolls need to be sampled and tested to detect whether their tensile properties meet the requirements. At the same time, the tensile performance parameters of the paper need to be obtained to facilitate the adjustment of the operating parameters of the conveyor rollers in the production equipment.
