In the auxiliary sample scraping device, the height of the outer edge 12 of the wooden tray 1 is higher than that of the upper plane 21, and the height of the communication port 22 is not lower than half of the height of the hollow metal box 2.
In the auxiliary sample scraping device, the air holes 211 are circular holes with the diameter of 5mm, and the distance between the adjacent air holes 211 in the same row and the distance between the adjacent air holes 211 in the same column are both 2 cm.
In an auxiliary sample scraping device as described above, the hollow metal box 2 is rectangular, and the air holes 211 are in a rectangular array of 6 rows by 11 columns in the middle of the upper plane 21.
In the auxiliary sample scraping device, the inner diameter of the air pipe 3 is 5 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the structure of the scheme is simple and easy to realize, the practicability is good, the arrangement of the air holes on the upper plane of the hollow metal box and the arrangement of the hollow metal box which is connected with the air pump through the air pipe are convenient for sucking the paint film sample scraping card paper placed on the upper plane through negative pressure, so that the paint film sample scraping card paper is tightly attached to the upper plane to scrape samples on the paint film sample scraping card paper, and the arrangement of the rectangular array of the air holes is convenient for uniformly adsorbing the paint film sample scraping card paper; the structure that the hollow metal box is placed on the wooden tray facilitates the flow of redundant paint into the wooden tray and the subsequent uniform treatment.
2. The height of the outer edge of the wooden tray is higher than that of the upper plane, so that excess paint can be better collected, the height of the communication port is not lower than half of the height of the hollow metal box, and the situation that the communication port is easily blocked when the paint flows into the hollow metal box through the air hole can be reduced.
3. The air holes are all round holes with the diameter of 5mm, the aperture of the air holes is small, the paint film sample scraping paperboard is not easy to deform due to negative pressure suction, the space between every two adjacent air holes in the same row and the space between every two adjacent air holes in the same column are both 2cm, namely, one air hole is arranged every 2cm to adsorb the paint film sample scraping paperboard, the arrangement interval is moderate, and the adsorption effect is good.
