Description

Technical Field

[0001] The utility model relates to the technical field of samplers, and particularly to a sampler for water-based glue. Background Art

[0002] Water-based glue is an adhesive with water as the solvent or dispersion medium, and a large amount of water-based glue is required in the cigarette production process. In the tobacco industry, the use of water-based glue needs to strictly implement the concepts of health and environmental protection, and the water-based glue used needs to be strictly inspected. Therefore, extracting water-based glue samples and testing them in the laboratory has become one of the important daily tasks. The extraction process of water-based glue samples needs to be representative, and the water-based glue samples must be pure and free from external contamination to ensure the accuracy of the test data.

[0003] In the prior art, there are mainly two ways to extract water-based glue: the first is to tilt or move the water-based glue tank body and pour the water-based glue into the sampling bag; the second is to use a container to hold it and then pour it into the sampling bag. Since the water-based glue tank bodies are relatively heavy and difficult to move, the direct pouring method in the first method is extremely laborious and there is a risk of tipping over the water-based glue tank body, causing personal injury and property loss; for the method of using a container to hold it and then pour it into the sampling bag, due to the many links in the sampling process, it is easy to cause sample contamination, thus affecting the test results. Therefore, the current sampling methods are both time-consuming and laborious and risky. Content of the Utility Model

[0004] To solve at least one of the above problems, the utility model provides a sampler for water-based glue, which uses the pressure difference between a sampling bag in a vacuum state and the water-based glue tank body to be tested to extract the water-based glue into the sampling bag. By using an air extraction device to evacuate the sealed tank to a vacuum, it helps to reduce the resistance when the liquid extraction bag expands during the liquid suction process. The sampler of this application is small, light and easy to operate. During the sampling process, there is no need to laboriously move the water-based glue tank body, and it will not contaminate the water-based glue sample, avoiding possible dangers and ensuring the accuracy of the test data.
