Description

Technical Field

[0001] The invention relates to the technical field of flour detection, and in particular to a flour sampling device and a sampling method based on flour processing detection. Background Art

[0002] Flour is a fine powder made by grinding wheat or other grains (such as barley, oats, corn, etc.). It is one of the most basic raw materials in cooking and baking. It is used to make a variety of foods such as bread, pastries, noodles, dough, etc. The main component of flour is starch, and it also contains a certain amount of protein (i.e. gluten), vitamins and minerals. Different types of flour have different uses due to their different protein content. The quality of the flour needs to be tested before packaging to ensure the safety of the flour.

[0003] Publication No. CN116296604B discloses a flour detection sampling device, which includes a sampling tube, a sampling box, a square trough, a collecting bucket, a hydraulic cylinder, a piston, a push rod and a connecting plate; the hydraulic cylinder, through the linkage of the connecting plate, pushes the push rod to slide from the inside of the sampling tube, drives the piston to slide into the inside of the sampling tube, so that negative pressure suction is generated inside the sampling tube. At the same time, in conjunction with the high pressure inside the conveying pipeline, part of the flour transported inside the conveying pipeline enters the inside of the sampling tube, the sampled flour enters the inside of the sampling box, and the sampled flour falls into the inside of the collecting bucket, completing the sampling work.

[0004] Although the above application and the prior art can facilitate testers to accurately collect flour samples at different stages in the early, middle and late stages of the flour production process, when the flour is being transported and packaged, the flour will accumulate on the conveyor table, making it inconvenient to sample and test the flour at different depths and positions. In addition, when sampling, since the flour is not blocked on the conveyor table, the flour will be displaced during sampling, resulting in a lack of complete test samples in the sampling box. In addition, since the flour needs to be tested continuously, in order to avoid cross contamination, the sampling box needs to be cleaned after the test is completed to facilitate the next test. Therefore, we propose a flour sampling device and sampling method based on flour processing detection. Summary of the invention

When the interior of the sampling box 234 needs to be cleaned, when the sampling box 234 is moved to the initial position, the driving cylinder 24 is continuously started, and the driving cylinder 24 drives the iron ring 242 to move through the telescopic rod 241, so that the iron ring 242 drives the moving block 231 to move through the magnetic ring 233. When the telescopic rod 241 continues to move, the iron ring 242 and the magnetic ring 233 are separated from each other, and the telescopic rod 241 The movable plate 33 is squeezed through the fixed cylinder 32 and the extension cylinder 323, so that the movable plate 33 drives the cleaning plate 331 to move inside the sampling box 234, and then the cleaning plate 331 cleans out the flour inside the sampling box 234, and then the inside of the sampling box 234 is cleaned, thereby avoiding cross contamination of flour during subsequent sampling. During the movement of the movable plate 33, the movable plate 33 stretches the spring 322 through the extension cylinder 323. When the cleaning plate 331 cleans the inside of the sampling box 234, the telescopic rod 241 retracts, and the spring 322 returns to its original state because it is not stretched by the movable plate 33, and then drives the movable plate 33 and the cleaning plate 331 to return to their initial positions through the extension cylinder 323.

This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness. Small angular errors are allowed. For example, an assembly error range of less than 10 degrees can be understood as a parallel relationship.

It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.
