Description

Technical Field

[0001] The present invention relates to the technical field of paper testing, and more particularly to a finished paper adhesion testing device. Background Art

[0002] During the production, storage, and transportation of finished paper, interlayer adhesion is prone to occur due to factors such as surface tension, humidity fluctuations, and residual additives. This problem has a significant impact on industries such as printing, packaging, and publishing. For example, sticking can cause jams on printing presses and shutdowns on packaging production lines, reducing production efficiency and potentially damaging the paper, increasing costs. For high-precision printing papers (such as coated paper and security paper), even minor adhesion can damage the surface coating or pattern, directly impacting product quality. Therefore, accurately measuring the adhesion strength of finished paper has become a critical step in quality control and process optimization for paper manufacturers.

[0003] Currently, many paper adhesion testing devices on the market have limitations: traditional manual testing devices rely on manual operation and measure peeling force through weights or simple tensile gauges, which is not only inefficient but also difficult to control parameters such as tension speed and angle, resulting in large errors in test data; although some semi-automatic equipment can perform basic tensile testing, they lack the ability to pre-process the surface state of paper (such as wrinkle smoothing) and dynamic monitoring, and cannot simulate complex scenarios in actual production. At the same time, the intelligent analysis and traceability functions of test data are insufficient, making it difficult to meet the high-precision and high-efficiency quality inspection requirements of modern manufacturing. Therefore, in order to solve the above problems, the existence of a finished paper adhesion testing device is crucial. Summary of the Invention
