Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampler technology, and more specifically, relates to the Cobb sampler. Background Technology
[0002] In many industries such as papermaking, packaging, and related scientific research and quality supervision and inspection, it is crucial to accurately determine the water absorption and oil permeability of paper and paperboard. Water absorption, as a key technical indicator characterizing the water absorption capacity of paper and paperboard surfaces, has a profound impact on product quality and application. In order to accurately determine the water absorption of paper and paperboard, the industry uses the Cobb method, which measures the mass of water absorbed by a unit area of paper and paperboard surface within a specified time. The Cobb sampler is an essential tool in the Cobb test, which can quickly and accurately cut standard-sized samples. To facilitate the experiment, a Cobb sampler is needed.
[0003] Based on existing technology, it has been found that existing Cobb samplers mainly use a downward cutting method when cutting and sampling test paper. However, this type of sampler has significant limitations in practical applications. Its cutting mold can often only be adapted to a single size specification. When performing sampling operations, it can only produce samples of a specific size and cannot flexibly switch to other sizes. As a result, it is difficult to meet the different requirements of paper sample size for different tests when facing diverse test needs, which seriously restricts the application efficiency of Cobb samplers in multi-scenario tests. Utility Model Content

However, their cutting molds are often only compatible with a single size specification. When performing sampling operations, they can only produce samples of a specific size and cannot flexibly switch to other sizes, making it difficult to meet the differentiated requirements of different tests for paper sample size.
