Description

Technical Field

[0001] The present application relates to coating testing technology, and particularly to a sag resistance testing scraping and leveling jig. Background Art

[0002] For most coatings, after obtaining the trial production samples, various parameters need to be measured, so as to feed back to the R & D work to adjust the preparation process and optimize the coating performance. Among them, the sag resistance performance is an important index of the coating. According to the requirements of relevant standards, in the test, a small amount of the sample to be tested is added to the surface of the test panel, and then a sag meter is used to move along a straight line close to the panel surface to scrape the sample flat, forming multiple scraping coatings with a straight interval. Then, the panel is erected so that each scraping coating points horizontally, and the sagging situation is observed. In this process, the requirement for the collimation of the operator's movement of the sag meter is relatively high, and it must be stable and maintain a high degree of collimation to keep the interval and straightness of each scraping coating, so as to ensure the effectiveness and reference degree of the test results. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies of the prior art, the present application provides a sag resistance testing scraping and leveling jig, which is applied to the sag resistance performance test of coatings, and realizes stable and collinear movement when operating the sag meter, so as to ensure that each scraping coating obtained by scraping the sample flat has better collimation.

[0004] In order to achieve the above purpose, the present utility model adopts the following technologies:

[0005] A sag resistance testing scraping and leveling jig includes a pair of guide frames arranged at intervals and symmetrically on a workbench and a push-scraping assembly that cooperates with the guide frames during use;

[0006] The guide frame includes a horizontal guide rail provided inside the side plate, a section of limit plate located on the horizontal guide rail, an upper limit platform located at one end of the horizontal guide rail, and an end limit plate located at the outer end of the upper limit platform. One end of the limit plate facing the upper limit platform has a predetermined interval from the upper limit platform, and the surface of the upper limit platform is higher than the surface of the horizontal guide rail by a predetermined distance;

[0007] The push-scraping assembly includes a clamping cavity and horizontal rods connected to both ends of the clamping cavity. The clamping cavity is used to clamp the sag meter, and the horizontal rods are used to rest on the horizontal guide rail or the upper limit platform during use and contact and cooperate with the inner side of the side plate.

[0008] The workbench area between the guide frames is used to place the test panel. When the horizontal rod cooperates with the horizontal guide rail, the bottom surface of the sag meter clamped in the clamping cavity is attached to the surface of the test panel, and the limit plate performs upper limit on the horizontal rod.

[0009] The beneficial effects of the present utility model are as follows:

[0010] 1. Applied to the anti-sagging performance test of coatings, it realizes stable and straight movement when operating the sag gauge to ensure that each scraped coating obtained by scraping the sample has good straightness.

[0011] 2. By setting the upper limit platform and a predetermined interval, it is convenient to take out, put in and temporarily place the pushing and scraping component for use.

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0016] An embodiment of the present application provides an anti-sagging test scraping fixture, which is arranged on a workbench. As Figure 1 shown, it includes a guide frame 2, a pushing and scraping component 3, etc.

[0017] Among them, there is a pair of guide frames 2 spaced and symmetrically arranged on the workbench. The workbench area between the guide frames 2 is used to place the test sample 1. When in use, the pushing and scraping component 3 cooperates with the guide frame 2. After adding a coating sample to the test sample 1, scraping treatment can be carried out through the pushing and scraping component 3 to form a scraped coating to be measured.

[0018] Specifically, in this example, as Figure 2 shown, the guide frame 2 includes a horizontal guide rail 21 arranged inside the side plate 20, a section of limit plate 22 located on the horizontal guide rail 21, an upper limit platform 24 located at one end of the horizontal guide rail 21, and an end limit plate 25 located at the outer end of the upper limit platform 24.

[0019] As Figure 1As shown, the push-scraping assembly 3 includes a clamping cavity 32 and horizontal rods 31 connected to both ends of the clamping cavity 32. The clamping cavity 32 is used to clamp the sag meter 4, which can be fastened by a locking member arranged on the cavity wall. Specifically, one end of the clamping cavity 32 is provided with a baffle, so that when the sag meter 4 is inserted into the cavity, it is limited from one side, and then the sag meter 4 can be fixed by the locking member, for example, locking screws can be arranged at both ends of the clamping cavity 32 to complete the fastening. The top of the clamping cavity 32 is provided with a handle, which is convenient for pulling the push-scraping assembly 3 when scraping.

[0020] The horizontal rod 31 is used to be supported on the horizontal guide rail 21 or the upper limit platform 24 when in use. When supported, it contacts and fits with the inner side of the side plate 20 and is always limited by the outer end of the side plate 20.

[0021] Combination Figure 1 and Figure 2 As shown, the end of the limit plate 22 facing the upper limit platform 24 has a predetermined interval with the upper limit platform 24 to leave a gap for the push-scraping assembly 3 to be taken out or put in, and the specific gap is based on the horizontal rod 31 being able to pass vertically. The surface of the upper limit platform 24 is higher than the surface of the horizontal guide rail 21 by a predetermined distance, so that when the scraping blade is not needed, the push-scraping assembly 3 can be connected to the upper limit platform 24 through the horizontal rod 31 to achieve overhead placement.

[0022] When the horizontal rod 31 is matched with the horizontal guide rail 21, the bottom surface of the sag meter 4 clamped in the clamping cavity 32 fits with the surface of the test sample 1, and is set to fit tightly as much as possible. This can be achieved by setting a rubber pad layer in the clamping cavity 32, and the limit plate 22 sets an upper limit on the horizontal rod 31.

[0023] When applied, such as Figure 3 As shown, a test sample 1 is set between the guide frames 2, and then the push-scrape assembly 3 is taken out first, and the sag meter 4 is installed in the clamping cavity 32, and then it enters between the guide frames 2 through the predetermined interval, and then the horizontal rod 31 is temporarily supported on the upper limit table 24 to realize the temporary placement of the push-scrape assembly 3. At this time, the sag meter 4 is higher than the test sample 1; then, the paint sample to be tested is added to the test sample 1, and then the horizontal rod 31 is supported on the horizontal guide rail 21. The sag meter 4 is now attached to the test sample 1, and the operating handle is pulled to make the push-scrape assembly 3 move in a straight line with the horizontal rod 31 under the limitation of the horizontal guide rail 21 and the limit plate 22, so that the sag meter 4 can maintain a stable and aligned manner to scrape the sample to form a straight scraping coating with uniform spacing.

[0024] 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.
