Sampling and testing during the production process or before shipment is essential for quality control. Sampling equipment for post-production lacquer testing must be accurate, efficient, and non-contaminating. Ensuring sample representativeness, avoiding contamination, and proper storage are crucial to successful testing.

[0005] Although the above patent facilitates the control of the connection between the feed hole and the first through hole and the sealing of the storage chamber, speeds up the sampling rate of the paint, and at the same time uses reinforcing ribs to improve the overall hardness of the sealing plate, thereby increasing the service life of the device, it is not convenient for accelerating the efficiency of sucking the paint into and out of the sampling tube, and it is difficult to shorten the sampling time.

Since the partition plate divides the interior of the sampling tube into multiple groups of cavities, the connecting rod pulls the piston to slide inside the sliding sleeve, and a negative pressure state is formed inside the cavity, thereby achieving the effect of accelerating the absorption of paint into the sampling tube. When discharging, the sliding plate on the other side of the sampling tube opens, pressing down the piston to accelerate the discharge, thereby shortening the sampling time and improving work efficiency. At the same time, it can ensure that the composition and properties of the paint remain stable during the sampling process, avoiding composition changes or contamination caused by excessively long sampling time.

When in use, the operator pushes the handle and uses the rolling of the universal wheel to drive the sampling tube to move above the position to be detected, and then starts the drive motor to drive the threaded rod to rotate. The threaded rod rotates inside the connecting block, driving the connecting block to slide in the slide groove on the positioning frame. The sliding of another set of connecting blocks on the stabilizing rod plays a stabilizing role, thereby achieving the effect of lifting the sampling tube, conveniently sampling from different depths or positions, without the need for frequent manual replacement or adjustment of the sampling position, thereby improving the efficiency and flexibility of sampling.
