Description

Technical Field

[0002] A paint film, also known as a coating film, is a solid continuous film formed by applying one or more coatings on a substrate. Usually, the coating film consists of multiple coatings, and the number of coatings is determined according to the requirements of the object to be coated. Generally, it includes a primer layer, an intermediate coating layer, and a topcoat layer. After the paint is produced, an elasticity experiment needs to be carried out to measure the flexibility of the paint film.

[0003] For example, the Chinese utility model patent with the application number CN201521052143.3 discloses a device for quickly detecting the elasticity of a paint film, which includes two flat plates with upper surfaces for preparing the paint film, and a handle is fixedly arranged on each flat plate; one side surfaces of the two flat plates are hinged together, and the hinge is located at the lower edge of the contact surface of the two flat plates, so that the two flat plates can only rotate downward around the hinge. The utility model has simple operation and can truly and intuitively reflect the elasticity and elastic life of the paint film after actual coating.

[0004] However, the disadvantage of the above patent is that during detection, manual folding is required by hand. In order to make the measurement of the experimental results more accurate, multiple measurements are required in actual detection, and thus manual folding back and forth is needed, which consumes a large amount of time and labor. As a result, it is very difficult for workers to achieve an ideal measurement effect during the folding process, leading to unstable measurement quality. Summary of the Utility Model

[0034] As Figure 1 shown, an embodiment of the present utility model provides a device for measuring the elasticity of a paint film, including a flat plate 1, a flap 2 rotatable on the flat plate 1, and a cycle number counting device. The specific structure and working principle of the cycle number counting device can be referred to the existing Chinese patent document CN201521052143.3, and will not be described in detail here;

[0035] It further includes a rotating shaft 3 and a driving member 4 for driving the rotation of the rotating shaft 3. Concave portions are provided on the upper surfaces of both the flat plate 1 and the flap 2, and the two concave portions communicate to form a receiving groove 5 for preparing the paint film, and the receiving groove 5 has a rectangular structure;

[0036] The flap 2 is located at one end of the flat plate 1 and their end sides are close to each other. Axial holes 6 matching the rotating shaft 3 are radially penetrated through the end sides of the platform and the flap 2 close to each other. The axial holes 6 are connected and matched with the flap 2 and the rotating shaft 3 to form a whole, so that under the action of the driving member 4, the rotating shaft 3 is driven to rotate to make the flap 2 rotate downward around the axial hole 6.

[0037] In the embodiment of the present utility model, during use, the liquid latex paint is poured into the receiving groove 5 on the flat plate 1 and the flap 2. After the coating is cured for a certain time, the coating adheres firmly to the surface of the flat plate 1. Then, the driving member 4 is used to drive the rotation of the rotating shaft 3, so that the flap 2 can be rotated until cracks appear in the paint film attached to the upper surface of the receiving groove 5, thereby measuring the elasticity of the paint film. Its operation is simple and convenient, and the measurement quality is stable.

[0038] As Figures 3 - 5As shown in the figure, in the embodiment of the present utility model, a dovetail groove 21 is provided on the end surface of one side of the flap 2, and the dovetail groove 21 penetrates through the flap 2 and communicates with the shaft hole 6; an installation groove 31 is provided on the rotating shaft 3, and a dovetail key 7 is inserted between the dovetail groove 21 and the installation groove 31.

One trapezoidal block cooperates with the dovetail groove 21 on the flap 2, and the other trapezoidal block cooperates with the installation groove 31 on the rotating shaft 3. And the cross-section length in the middle is less than the bottom lengths on the upper and lower sides. Through the cooperation of the dovetail key 7 with the dovetail groove 21 on the flap 2 and the installation groove 31 on the rotating shaft 3 respectively, the flap 2 and the output shaft are connected into one body, and the dovetail key 7 limits to prevent separation, and at the same time is convenient for disassembly and installation.
