Description

Technical Field

[0001] The present invention relates to the technical field of coating detection, and in particular to a device suitable for detecting the fluidity of coating. Background Art

[0002] Paint is a functional material coated on the surface of an object. It can be coated on the surface of an object using different processes to form a solid film that is firmly adhered, has a certain strength, and is continuous. Before coating, in order to ensure the coating quality, after developing a new coating, it is usually necessary to test the fluidity of the new coating. Paint fluidity testing is not only the basis for ensuring product performance, but also the core link to promote industry technological innovation and meet the needs of diverse application scenarios.

[0003] In the prior art, patent publication number CN118225630B discloses an industrial coating fluidity testing device and its use method. A drive assembly drives two test cylinders to flip vertically, swapping their positions and allowing the paint in the two test cylinders to alternately flow downward, enabling rapid, repeated testing of the coating within the test cylinders. While the entire test process does not require frequent refilling to complete repeated testing, existing cone bucket testing methods typically require manual intervention to ensure the coating within the cone bucket is calm and its upper surface is level before testing can proceed. However, each time the two test cylinders are switched, the coating within them must rely on time to gradually return to a stable surface before repeated testing can be performed. During this waiting time for reciprocating switching, the probability of coating solidification and sagging increases, resulting in differences in the total amount of coating and flow resistance during multiple tests, which in turn affects the coating fluidity test results.

[0019] Example 1 This embodiment discloses a device suitable for testing the fluidity of a coating, which is used to repeatedly perform fluidity tests on the same coating sample and determine the coating fluidity based on the average measured value.

[0020] like Figures 1-4As shown, the detection equipment includes a base 1, on which two loading frames 2 distributed in a front and rear mirror image are fixed, and a ring frame 3 is fixed on the base 1. Both the loading frames 2 and the ring frame 3 are high-strength steel structures, and both are connected to the base 1 by bolts. The ring frame 3 consists of an upper half and a lower half, and the two parts are also connected by bolts. An electric rotating shaft 4 is provided on the loading frame 2, and the axis of the electric rotating shaft 4 coincides with the axis of the ring part of the ring frame 3. A transfer block 5 is fixed between the two electric rotating shafts 4, and a through hole is provided on the transfer block 5. The upper and lower sides of the transfer block 5 are provided with a truncated cone surface. In order to guide the flow of paint, a solenoid valve 501 is provided in the through hole of the transfer block 5, and a flow detection module (visual detection module, which is a prior art and not shown in the figure) for detecting the flow state of the paint is provided in the through hole of the transfer block 5, and the flow detection module will not affect the normal flow of the paint. A control panel (not shown in the figure) is provided on the base 1, and the control panel is electrically connected to the electrical components in the device, and a timing module is provided in the control panel. The transfer block 5 is fixed with a mirror-distributed loading shell 6, and the loading shell 6 is made of a transparent material to facilitate observation of the paint state. The loading shell 6 is slidably connected to the annular frame 3, and the outer surface of the loading shell 6 is The surfaces are all smooth to reduce the sliding friction between the loading shell 6 and the annular frame 3. When installing this equipment, first install the loading frame 2 and the lower half of the annular frame 3 on the base 1, then install the parts on the loading frame 2, and finally install the upper half of the annular frame 3, so as to wrap the two loading shells 6. The two loading shells 6 are connected through the transfer block 5 and the solenoid valve 501. The loading shell 6 is fixedly connected and connected with a feed pipe 7. An electric control valve is provided in the feed pipe 7, and the electric control valve is located on the side close to the loading shell 6. The fixed connection between the feed pipe 7 and the loading shell 6 is located on the side of the loading shell 6 close to the transfer block 5. When filling the material, connect the feed pipe 7 located on the upper loading shell 6 with the feed pipe, and then inject the material into the upper loading shell 6. Since the vertical distance between the feed pipe 7 and the transfer block 5 is short, no large drop will be generated during injection, thereby reducing the amount of bubbles generated by the paint. A slow flow unit is provided in the loading shell 6; the slow flow unit includes a sliding ring 8, which is slidably connected to the inner side of the loading shell 6, and the inner ring of the sliding ring 8 is fixed with a buffer net 9. The buffer net 9 is made of flexible polyethylene and is used to reduce the probability of paint adhesion. The buffer net 9 is used to provide resistance to the flow of paint, and the sliding ring 8 is provided with a damping mechanism for providing damping force.

[0021] like Figure 3 、 Figure 4 and Figure 6As shown, the damping mechanism includes two sliding frames 10 distributed in a front-to-back mirror image, and the two sliding frames 10 are fixed to the sliding ring 8. The sliding frames 10 are slidably connected to the carrier shell 6, and a dynamic seal is formed between the two. The carrier shell 6 is fixed with two damping shells 11 distributed in a front-to-back mirror image, and the damping shell 11 is sealed and slidably connected to the sliding frame 10. Viscous damping fluid (hereinafter referred to as damping fluid) is injected into the damping shell 11. A damping plate 12 is fixed to the side of the sliding frame 10 close to the damping shell 11. The damping plate 12 is located in the damping shell 11, and the diameter of the damping plate 12 is smaller than the inner diameter of the damping shell 11 (that is, there is an annular gap between the two). The damping plate 12 is provided with through holes distributed at intervals, and a one-way valve 13 is installed in the through hole of the damping plate 12 to prevent the damping fluid from being injected into the damping shell 11. Figure 6 For example, the one-way valve 13 in the one-way valve 13 has a flow direction from bottom to top. The sum of the flow areas of all the one-way valves 13 on a damping plate 12 is equal to the annular gap area between the damping plate 12 and the damping shell 11, that is, the upward resistance of the damping plate 12 is greater than the downward resistance. A spring 14 is fixed between the damping plate 12 and the damping shell 11. Under normal conditions, the two springs 14 are sufficient to lift the sliding ring 8 and the buffer net 9 (such as Figure 4 The damping shell 11 is sealed and slidably connected to the movable plate 15. A through hole is provided on one side of the damping shell 11 close to the movable plate 15. When the damping plate 12 and the sliding frame 10 move downward, the damping fluid in the damping shell 11 is squeezed and drives the movable plate 15 to move downward.

[0022] The working process of the detection device in this embodiment is as follows: Test preparation: Control the two electric shafts 4 to drive the two loading shells 6 to rotate until the axis of the loading shell 6 is perpendicular to the horizontal plane and then stops rotating. Connect the external paint supply pipeline with the upper feed pipe 7 and open the internal electric control valve. Inject a certain amount of paint into the upper loading shell 6. Then disconnect the external paint supply pipeline and close the electric control valve in the feed pipe 7. The preparation work is completed.

[0023] Testing process: After observing that the paint liquid surface is calm, open the solenoid valve 501, and at the same time, the timing module in the control panel starts timing. Under the action of gravity, the paint in the upper loading shell 6 flows into the lower loading shell 6 through the solenoid valve 501 under the guidance of the upper circular table of the transfer block 5. In the initial stage of the paint falling, the paint falling into the lower loading shell 6 is restricted by the lower buffer net 9, thereby reducing the sputtering range, helping the paint to gather faster while reducing the probability of bubbles appearing, until the paint in the upper loading shell 6 flows into the lower loading shell 6. At this time, no more paint passes through the solenoid valve 501, and the solenoid valve 501 is closed, and the timing module in the control panel stops timing. This data is the first flow time of the paint, and then the electric shaft 4 is controlled to drive the two loading shells 6 to rotate 180°, so that the positions of the upper and lower loading shells 6 are reversed.

[0024] During the process of the two loading shells 6 rotating 180 degrees, when the two loading shells 6 rotate to a horizontal state, the paint in the lower loading shell 6 moves toward the transfer block 5. At the same time, under the viscosity of the paint and the push of the paint on the sliding ring 8 and the buffer net 9, the sliding ring 8 and the buffer net 9 are gradually pushed and move toward the transfer block 5. The sliding ring 8 drives the damping plate 12 to move synchronously through the sliding frame 10. The damping fluid on the side of the damping plate 12 away from the sliding frame 10 passes through the annular gap between the damping plate 12 and the damping shell 11 and the spaced apart The one-way valve 13 gradually moves toward the side close to the sliding frame 10, and at the same time compresses the spring 14. As the rotation continues, the lower loading shell 6 gradually tilts upward, and the paint in the loading shell 6 continues to squeeze and drive the sliding ring 8 and the buffer net 9 to move toward the transfer block 5. In this process, the buffer net 9 gradually changes from protruding in the direction away from the transfer block 5 to protruding in the direction close to the transfer block 5. The positions of the upper and lower loading shells 6 are interchanged. At this time, the paint is gathered near the transfer block 5 and presents a mixed flow fluctuation state. The state of the sliding ring 8 and the buffer net 9 is as follows: Figure 9 As shown, the thrust of the paint on the sliding ring 8 and the buffer net 9 gradually decreases, and the spring 14 drives the sliding ring 8 and the buffer net 9 to gradually move upward and reset through the damping plate 12 and the sliding frame 10. Since the buffer net 9 is immersed in the paint at this time, the grid on the buffer net 9 restricts the flow channel of the paint, thereby increasing its flow resistance. The mixed flow fluctuations in the paint will be blocked and buffered by the buffer net 9, thereby reducing the degree of its mixed flow fluctuations.

[0025] When the sliding frame 10 drives the sliding ring 8 and the buffer net 9 to move upward, the damping fluid on the side of the damping plate 12 close to the sliding frame 10 can only move to the side away from the sliding frame 10 through the annular gap between the damping plate 12 and the damping shell 11, so the sliding ring 8 and the buffer net 9 move upward slowly, and under the impact of the paint mixed flow fluctuation, the upward movement speed of the sliding ring 8 and the buffer net 9 is further delayed until the paint mixed flow fluctuation in the loading shell 6 gradually disappears, the upward movement speed of the sliding ring 8 and the buffer net 9 is restored, and the buffer net 9 is in a free hanging state under the action of gravity, and the buffer net 9 gradually loses contact with the paint, and in this process, the contact area of ​​the buffer net 9 with the paint gradually decreases until the sliding ring 8 and the buffer net 9 are reset (such as Figure 4As shown in the state), repeat the above operation to continue the paint fluidity test until the two loading shells 6 are switched five times. At this time, the control panel records six data, and the data of two adjacent loading shells 6 are a group. The average value is calculated, and then the three groups of common average values ​​are calculated again based on the average values ​​calculated by each of the three groups. The average flow time of the paint can be obtained, and the paint fluidity can be determined or calculated based on the average flow time. The sliding ring 8 cooperates with the buffer net 9 to limit the splashing range of the paint when it falls, and assist the paint to gather faster. When the loading shell 6 is rotated and switched, the mixed flow fluctuating paint is restrained and buffered, which accelerates its recovery to a stable state, shortens the detection time, and thus reduces the probability of the paint solidifying and sagging, thereby improving the accuracy of the detection data.

[0026] Example 2 This embodiment discloses a device suitable for detecting the fluidity of coatings, which is further improved on the basis of the first embodiment.

[0027] The structure, connection relationship and working process of the detection device in Example 1 will not be described in detail. The working principle of the following structure will be explained in detail, and the same applies to subsequent embodiments.

[0028] like Figure 3-Figure 5 As shown, the side of the loading shell 6 away from the transfer block 5 is set to be hemispherical, and its surface is smooth, which is used to guide the paint to flow smoothly and reduce the probability of paint accumulation. An inclined surface 16 is connected between the hemispherical part of the loading shell 6 and the inner wall of the loading shell 6, and the angles between the inclined surface 16 and the longitudinal sections of the hemispherical part of the loading shell 6 and the side wall of the loading shell 6 are all obtuse angles. A flow-blocking surface 17 is provided on the side of the sliding ring 8 away from the transfer block 5, and the angle between the flow-blocking surface 17 and the longitudinal section of the inclined surface 16 is an obtuse angle. The hemispherical part of the loading shell 6 is smoothly connected to the side wall of the loading shell 6 (the connection is the inclined surface 16), and because the angles between the inclined surface 16 and the hemispherical part of the loading shell 6 and the side wall of the loading shell 6, and between the flow-blocking surface 17 and the longitudinal section of the inclined surface 16 are all obtuse angles, the sliding ring 8 passes through the attachment. The paint near the coating forms a high-curvature curved liquid surface. According to the Laplace equation, the larger the radius of curvature, the smaller the pressure difference caused by surface tension. The surface tension of the liquid is small, and it is not easy to form accumulation at the tail end of the coating flow, that is, the retention effect of the surface tension is reduced, further ensuring the accuracy of the data measured by this equipment. A cleaning surface 18 is provided on the side of the sliding ring 8 close to the transfer block 5, and the angle between the cleaning surface 18 and the longitudinal section of the flow-blocking surface 17 is an acute angle. When the sliding ring 8 moves upward, the flow-blocking surface 17 is more likely to guide the residual coating remaining on the side wall of the loading shell 6 to the connection between the flow-blocking surface 17 and the cleaning surface 18 and collect them. After the collection is completed, it falls into the coating. The angle between the cleaning surface 18 and the longitudinal section of the side wall of the loading shell 6 is an obtuse angle, which is also used to reduce the probability of coating accumulation.

[0029] Example 3 This embodiment discloses a device suitable for detecting the fluidity of coatings, which is further improved on the basis of the second embodiment.

[0030] like Figure 7-Figure 9 As shown, the buffer net 9 is composed of a number of wefts 19 and a number of warp threads 20, and the buffer net 9 is hemispherical in its naturally hanging state, so as to fit the hemispherical portion of the loading shell 6 in the naturally hanging state. The diameters of the wefts 19 and the warp threads 20 gradually increase from the side close to the sliding ring 8 to the side away from the sliding ring 8. During the switching process of the two loading shells 6, the paint droplets on the buffer net 9 converge toward the center thereof, and the volume of the converged droplets gradually increases, thereby overcoming the adsorption force between the paint droplets and the buffer net 9 through the gravity of the liquid, thereby reducing the probability of liquid accumulation. All the warp threads 20 on the buffer net 9 are commonly fixed with a counterweight block 21, which is located in the center of the buffer net 9 and is used to assist the buffer net 9 in switching the protruding direction faster.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
