Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to an automatic sample scraping rotational rheometer. Background Art

[0002] Based on the definition of dynamic viscosity, rheometers simulate external construction conditions through rotation or shear motion to quickly measure the viscosity, modulus, molecular weight and other properties of materials such as rubber, emulsions, and coatings, providing an effective means for material development, application and quality control.

[0003] Currently, before a rheometer test begins, the sample must be loaded between the upper and lower clamps. Once the set distance is reached, the sample is manually scraped off with a spatula to prevent interference with the test. However, manual scraping is labor-intensive and inefficient. Furthermore, the amount of sample removed by different personnel may vary, leading to errors.

[0004] In the prior art, the application number is CN202122216192.8, and the application name is a rotational rheometer with automatic scraping. The technical solution recorded therein includes an installation chamber, a clamp unit and a scraping unit arranged in the installation chamber. The clamp unit is used to extrude a sample with a specified thickness and fix it; the scraping unit includes a scraper, an automatic telescopic module connected to the scraper, and a driving mechanism connected to the automatic telescopic module; the automatic telescopic module is used to adjust the distance between the scraper and the clamp unit. The automatic telescopic module drives the scraper to rotate around the clamp unit under the drive of the driving mechanism. During the rotation, the scraper scrapes the sample fixed by the clamp unit into a standard sample with a specified diameter; during the scraping process, the sample is squeezed and fixed by the clamp unit, and then rotates around the clamp unit by the scraping unit to scrape off excess sample. The operation is simple, the scraping is efficient, and the accuracy is high.

[0005] However, there are still some shortcomings in the actual use process. It is inconvenient to recycle the scraped materials, which easily leads to waste of resources. For this reason, we propose a new type of automatic scraping rotational rheometer. Utility Model Content
