Description

Technical Field

[0001] This utility model relates to the technical field of paint testing and sampling, and in particular to a sampling device for paint testing. Background Technology

[0002] Paint, traditionally known as varnish in China, is a viscous liquid applied to the surface of an object to be protected or decorated, forming a continuous, firmly adhering film. It is typically made primarily of resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared using organic solvents or water.

[0003] During the paint production process, it is necessary to sample and test the paint to determine whether its various properties meet the standards. Existing sampling devices are generally designed for sampling at a single height, resulting in insufficient representativeness. To address this, Chinese utility model patent CN220772676U discloses a sampling device for paint product spot checks. This device can extract samples from different heights; however, the paint sampled by this device is prone to evaporation, leading to inaccurate test data. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a sampling device for coating testing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A sampling device for paint testing includes a sampling tube. The inner cavity of the sampling tube is divided into several sampling chambers by several horizontal partitions arranged sequentially from top to bottom. Each sampling chamber has a sampling inlet / outlet at the lower end of its side wall. A piston rod is vertically installed inside the sampling tube, passing through all the sampling chambers. The top of the piston rod extends out of the sampling tube and is equipped with a sampling operation handle. A sampling piston is provided on the piston rod in each sampling chamber. Two horizontal support plates are provided at the upper end of the side wall of the sampling tube, and sealing baffles are inserted into the two horizontal support plates, with the sealing baffles tightly fitted to the sampling inlet / outlet.

[0007] Sealing rings are provided at the piston rod insertion points on the horizontal partition plates.

[0008] Each sampling chamber is equipped with an inclined guide plate at the bottom, with the lower end of the inclined guide plate located on the sampling inlet and outlet side.

[0009] The bottom of the sampling piston is provided with an inclined surface that cooperates with the inclined guide plate.

[0010] The enclosed baffle is equipped with a ramp, which is supported by a horizontal support plate on top.

[0011] A lifting handle is provided on the enclosed baffle.

[0012] A handle is provided on the upper side wall of the sampling tube.

[0013] The beneficial effects of this utility model are: it can take samples from different heights, ensuring that the samples are more representative; the closed baffle can seal the taken samples to prevent them from flowing out, preventing impurities from affecting or volatilizing, and ensuring that the sample performance can be detected more accurately.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] like Figure 1 As shown, a sampling device for coating testing includes a sampling tube 1, a horizontal partition plate 2, a sampling chamber 3, a sampling inlet and outlet 4, a piston rod 5, a sampling operation handle 6, a sampling piston 7, a horizontal support plate 8, a sealing baffle 9, a sealing ring 10, an inclined guide plate 11, a ramp 12, a lifting handle 13, and a grip handle 14.

[0025] A handle 14 is provided on the upper side wall of the sampling tube 1 to facilitate holding the sampling tube 1 during sampling.

[0026] The sampling tube 1 has several horizontal partition plates 2 arranged from top to bottom in the inner cavity. The horizontal partition plates 2 divide the inner cavity of the sampling tube 1 into several sampling chambers 3. Each sampling chamber 3 has a sampling inlet / outlet 4 at the lower end of its side wall. A piston rod 5 is vertically installed inside the sampling tube 1. The piston rod 5 passes through the inside of all the sampling chambers 3. The top of the piston rod 5 extends out of the sampling tube 1 and is equipped with a sampling operation handle 6. A sampling piston 7 is provided on the piston rod 5 in each sampling chamber 3.

[0027] This allows for sampling from different heights, ensuring that the samples are more representative.

[0028] Each sampling chamber 3 has an inclined guide plate 11 at its bottom, with the lower end of the inclined guide plate 11 located on the side of the sampling inlet and outlet 4. The bottom of the sampling piston 7 has an inclined surface that cooperates with the inclined guide plate 11. The inclined guide plate 11 makes it easier to discharge the sampled liquid.

[0029] Sealing rings 10 are provided on the horizontal partition plate 2 at the points where the piston rod 5 passes through, which can play a sealing role and prevent the sample from flowing.

[0030] Two horizontal support plates 8 are provided on the upper side wall of the sampling tube 1. A sealing baffle 9 is inserted on the two horizontal support plates 8. The sealing baffle 9 is tightly fitted with the sampling inlet and outlet 4.

[0031] The enclosed baffle 9 is provided with a mounting plate 12, which is supported on the horizontal support plate 8 above.

[0032] The enclosed baffle 9 is equipped with a lifting handle 13.

[0033] The sealed baffle 9 can seal the extracted sample, preventing it from flowing out and avoiding the influence of impurities or media in the air, thus ensuring that the sample performance can be detected more accurately.

[0034] In use, the closed baffle 9 is first pulled out using the lifting handle 13, as follows: Figure 2 As shown, the operator then holds the handle 14 and inserts the sampling tube 1 into the paint solution. Using the sampling operation handle 6, the piston rod 5 is lifted upwards. The sampling piston 7 draws paint at different heights into the corresponding sampling chambers 3 from different sampling inlets / outlets 4. Figure 3 As shown, after removing the sampling tube 1, the sealing baffle 9 can be inserted. Figure 4 As shown.
