Description

Technical Field

[0001] The present application relates to sample loading in testing, and in particular to a coating sample loading mechanism. Background Art

[0002] When testing the anti-sagging performance of paint samples, it is necessary to add a certain amount of paint trial samples to the test sample plate, and then use the sag meter to move in one direction to scrape the sample flat on the sample plate to form a strip coating. The straightness of these formed strip coatings is affected by the smoothness and collimation of the sag meter; and the uniformity of each coating strip is related to the uniformity of distribution in the designated area when the sample is added. Generally, the sample in the bottle is poured manually into the designated area of ​​the sample plate. If the operation is improper, it may cause unevenness, and a secondary operation is required to adjust. When pouring out the sample, the feeding position needs to be manually controlled each time to match the starting scraper position of the sag meter, which also has high requirements for operation and is not efficient.

[0008] The sample container has a plurality of feeding tubes at its bottom along its length direction. When in use, the sample container is placed on the placement rack, and the feeding tubes pass through the through holes;

[0009] In the initial state, one of the strip rods is located above the test bench, the length direction of the placement rack on the strip rod is consistent with the width direction of the sample placed on the test bench, and the placement rack is located above the sample, and the bottom end of the discharge tube of the sample container on the placement rack is projected onto the sample, and has a predetermined distance from the edge of the sample facing the test bench.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0015] The present application embodiment provides a coating sample feeding mechanism, such as Figure 1-Figure 2 As shown, the partition is arranged at one end of the test bench 1, and includes a cross 4, a sample container 5, etc.

[0016] Specifically, the cross 4 is rotatably arranged around its central axis, and the axis is consistent with the vertical direction. Specifically, a rotating column is connected to the center of the cross 4, and the rotating column is connected to a motor 42. The cross 4 includes four bar-shaped rods connected together in a cross shape. A placement rack 41 is provided at the end of each bar-shaped rod, and the length direction of the placement rack 41 is perpendicular to the length direction of the bar-shaped rod. The placement rack 41 is provided with a plurality of through holes along its length direction. Specifically, in combination with Figure 3 A plurality of feeding tubes 51 are provided at the bottom of the sample container 5 along its length direction.

[0017] During use, the sample container 5 is placed on the placement rack 41, and the feed tube 51 passes through the through hole.

[0018] In the initial state, if Figure 1 As shown, one of the strip-shaped bars is located above the test bench 1, and the length direction of the placement rack 41 on the strip-shaped bar is consistent with the width direction of the sample 2 placed on the test bench 1, and the placement rack 41 is located above the sample 2. The bottom end of the discharge pipe 51 of the sample container 5 on the placement rack 41 is projected on the sample 2, and has a predetermined distance from the edge of the sample 2 facing the test bench 1.

[0019] When in use, the sample container 5 is placed on each placement rack 41, and the feed tube 51 is passed through the through hole; then the sample plate 2 and the sag meter 3 are prepared on the test bench 1. The cross 4 is rotated to the initial state, at which time, the bottom end of the feed tube 51 is located above one side of the sag meter 3, which refers to the side of the sag meter 3 that is used for the forward direction when performing the scraping operation.

[0020] Then, pour the paint sample to be loaded into the sample container 5, and the sample will be relatively evenly loaded to one side of the sag meter 3 through the loading pipe 51. After the loading is completed, the sample container 5 can be taken away, and then the sag meter 3 can be operated to perform a scraping operation to form a strip coating.

[0021] After completion, the sample plate 2 and the sag meter 3 can be removed, and new sample plates 2 and sag meters 3 can be replaced. The cross 4 can be rotated to put the next sample container 5 in place, and the next sample can be loaded. Multiple samples can be loaded quickly, and the loading can maintain the consistency of the adding position, and has a good uniformity effect.

[0022] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
