Description

Technical Field

[0001] This utility model relates to the technical field of coating testing equipment, and in particular to a coating testing device. Background Technology

[0002] As is well known, paint, traditionally called lacquer in China, is a viscous liquid applied to the surface of an object to be protected or decorated, forming a continuous, firmly adhering film. It is typically composed of resin, oil, or emulsion as the main component, with or without pigments and fillers, and with appropriate additives, formulated with organic solvents or water. The application performance of paint is primarily determined by its flowability, the time required for the paint to form a film on the substrate, surface gloss, adhesion to the substrate, and the surface hardness of the cured paint.

[0003] For example, a Chinese utility model patent discloses a hardness testing device for waterproof coating production (Publication (Announcement) No. CN218098719U), which includes a base, with support plates on both the left and right sides above the base, and a support frame above the two support plates. This improves the reliability and stability of the test, reduces the skill requirements for manual operation, ensures the pencil tip makes precise contact with the paint film surface, improves ease of operation, and reduces experimental errors.

[0004] However, when the inventors implemented this device, they found the following drawbacks: it can only detect the hardness of paint, and its detection function is limited. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a coating testing device with diverse testing functions, capable of detecting the curing time of paint, the surface hardness after curing, and the adhesion between the paint and the substrate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a paint testing device, comprising a testing table, an mounting table mounted on the testing table, a testing station mounted on the mounting table, a rotating shaft mounted on the testing station, a rotating seat fixedly mounted on the rotating shaft, a substrate plate mounted on the rotating seat, a driving component that provides power for the rotation of the rotating seat, and a paint testing mechanism.

[0007] The driving component includes a driving cylinder and a rack mounted on the output end of the driving cylinder, and a gear that meshes with the rack is fixedly mounted on the rotating shaft;

[0008] The paint testing mechanism includes a mounting frame, a two-dimensional slide table mounted on the mounting frame, a first lifting driver mounted on the two-dimensional slide table, and a testing component mounted on the first lifting driver. The testing component includes a mounting base fixedly mounted on the first lifting driver, a slide seat slidably mounted on the mounting base, a hardness tester fixedly mounted on the slide seat, and a pressure sensor mounted on the top of the mounting base. The detection end of the pressure sensor is in contact with the top of the slide seat. Furthermore, the two-dimensional slide table adopts two mutually perpendicular mechanical slide tables, which can realize the two-dimensional movement of the hardness tester in a horizontal range. The first lifting driver is preferably a cylinder, but other equivalent drivers such as mechanical slide tables that have the effect of driving the mounting base to move up and down can also be used. In its natural state, the rotating seat is placed horizontally at the testing station.

[0009] As a preferred embodiment, the mounting platform is rotatably mounted on the testing platform, and there are multiple testing stations evenly distributed around the circumference of the mounting platform. A rotation driver is installed at the bottom of the testing platform to provide power for the rotation of the mounting platform. Furthermore, the rotation driver is preferably a braked stepper motor, but other drivers with the functions of driving the mounting platform to rotate and braking can also be used.

[0010] As a preferred embodiment, a receiving bucket is installed on the rotating base, the rotating base is perpendicular to the testing station, and the receiving bucket is tilted downwards to the side away from the center of the mounting platform.

[0011] As a preferred option, an open box is also included, placed on the testing table near the drive unit.

[0012] As a preferred embodiment, a second lifting driver is mounted on the two-dimensional slide, and a gloss meter is mounted on the second lifting driver.

[0013] As a preferred embodiment, the base plate is detachably mounted on the rotating base; furthermore, the base plate is detachably connected to the rotating base by bolts.

[0014] As a preferred embodiment, the testing station is provided with a groove that engages with the rack.

[0015] As a preferred embodiment, the substrate is provided with a standard coil.

[0016] Compared with the prior art, this utility model provides a coating testing device with the following beneficial effects: The coating testing device quantitatively drips coating onto a substrate, records the time it takes for the coating to fully cure using an external timer, activates a two-dimensional sliding stage to move a hardness tester above the substrate, activates a first lifting drive, causing the hardness tester to move downwards and contact the cured coating at its testing end, thus testing the surface hardness of the cured coating; the first lifting drive then moves the hardness tester upwards, actuates the drive cylinder, and causes the rack and pinion to contact the gear, which then rotates, causing the rotating seat to rotate from a horizontal position to an inclined position. Alternatively, in a vertical position, the first lifting drive restarts, and the detection end of the hardness tester contacts one side of the cured paint. The first lifting drive continues to operate, observing and recording the pressure detection value of the pressure sensor. When the cured paint detaches from the substrate, the operation stops. The maximum value detected by the pressure sensor during this period is the adhesion force of the paint on the substrate. It can detect the curing time of the paint, the surface hardness after curing, and the adhesion force between the cured paint and the substrate. It has multiple detection functions, effectively utilizes paint samples, and the various detection processes are interconnected, greatly improving the detection efficiency of paint.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1

[0032] Please refer to Figure 1-3 A paint testing device includes a testing platform 1, a mounting platform 23 mounted on the testing platform 1, a testing station 2 mounted on the mounting platform 23, a rotating shaft 3 rotatably mounted on the testing station 2, a rotating seat 4 fixedly mounted on the rotating shaft 3, a substrate plate 5 mounted on the rotating seat 4, a driving component that provides power for the rotation of the rotating seat 4, and a paint testing mechanism.

[0033] The driving component includes a driving cylinder 6 and a rack 7 mounted on the output end of the driving cylinder 6. A gear 8 that meshes with the rack 7 is fixedly mounted on the rotating shaft 3.

[0034] The paint testing mechanism includes a mounting frame 9, a two-dimensional slide 10 mounted on the mounting frame 9, a first lifting drive 11 mounted on the two-dimensional slide 10, and a testing component mounted on the first lifting drive 11. The testing component includes a mounting base 12 fixedly mounted on the first lifting drive 11, a slide 13 slidably mounted on the mounting base 12, a hardness tester 14 fixedly mounted on the slide 13, and a pressure sensor 15 mounted on the top of the mounting base 12. The detection end of the pressure sensor 15 is in contact with the top of the slide 13.

[0035] Mounting platform 23 is rotatably mounted on testing platform 1. There are multiple testing stations 2, which are evenly distributed around mounting platform 23. A rotation driver 16 is installed at the bottom of testing platform 1 to provide power for the rotation of mounting platform 23. Furthermore, the rotation driver 16 is preferably a brake stepper motor, but other drivers that can drive mounting platform 23 to rotate and brake can also be used.

[0036] The coating testing device provided in this embodiment has multiple testing stations 2, which can meet the synchronous drying and curing of different coatings or multiple groups of the same coating. By rotating the drive 16 to drive the mounting platform 23 to rotate, the testing station 2 is moved to the drive component and the testing components, realizing multiple groups of testing for the same coating, or step-by-step testing for multiple coatings, which can improve the testing efficiency of coatings.

[0037] Example 2

[0038] The coating testing device provided in Example 1 has been further optimized, specifically, as follows: Figure 3-4As shown, a receiving bucket 17 is installed on the rotating seat 4. The rotating seat 4 is perpendicular to the testing station 2, and the receiving bucket 17 is tilted downwards to the side away from the center of the mounting platform 23.

[0039] It also includes an open box 18 placed on the testing table 1 near the drive unit.

[0040] The paint detection device provided in this embodiment allows the paint peeled off from the substrate plate 5 to fall into the receiving hopper 17 when the rotating seat 4 is in an inclined or vertical state. After being guided by the receiving hopper 17, the cured paint block falls into the open box 18, preventing the peeled cured paint block from scattering to the mounting platform 23. The paint block can be collected in a concentrated manner, reducing the amount of manual cleaning work.

[0041] Specifically, a second lifting driver 19 is installed on the two-dimensional slide 10, and a gloss meter 20 is installed on the second lifting driver 19. By activating the two-dimensional slide 10, the gloss meter 20 is positioned above the station 2 to be tested. The second lifting driver 19 can drive the gloss meter 20 to move down, and the surface gloss of the paint is detected by the gloss meter 20, further enriching the detection function of the detection device.

[0042] Specifically, the substrate plate 5 is detachably installed on the rotating base 4; furthermore, the substrate plate 5 is detachably connected to the rotating base 4 by bolts; according to the testing standards of the coating, the substrate plate 5 of different materials or roughness can be replaced to test the adhesion of the coating under different materials and roughness, thereby improving the ease of disassembly and assembly of the substrate plate 5.

[0043] Specifically, the inspection station 2 is provided with a groove 21 that fits into the rack 7; when the rack 7 is inserted into the groove 21, the groove 21 can support the bottom of the rack 7, preventing the rack 7 from bending downward and shifting, and ensuring good meshing between the rack 7 and the gear 8.

[0044] Specifically, a standard coil 22 is provided on the substrate 5; paint can be dripped into the middle of the standard coil 22. If the paint does not flow out of the standard coil 22, it indicates that the paint has good viscosity. The size of the standard coil 22 can be appropriately selected according to the flow properties of different paints.

[0045] The process of using the coating testing device provided by this utility model is as follows: The coating is dripped into the center of the standard coil 22 on the substrate plate 5 at one of the testing stations 2. If the coating does not exceed the standard coil 22, the coating viscosity meets the requirements. The time it takes for the coating to fully cure after dripping can be recorded by an external timer. Then, the rotary driver 16 is activated, which drives the mounting platform 23 to rotate, moving the cured coating to the driving component. The two-dimensional slide 10 is then activated again, positioning the gloss meter 20 above the coating to be tested. After the second lifting driver 19 is activated, the gloss meter 20 descends, and the gloss of the cured coating surface is tested. The two-dimensional slide 10 is then activated again, moving the hardness meter 14 above the corresponding substrate plate 5. The first lifting driver 11 is then activated, and the hardness meter 14 is tested. The instrument 14 moves downward, and the detection end of the hardness tester 14 contacts the cured coating to test the surface hardness of the cured coating. The first lifting drive 11 drives the hardness tester 14 upward, the drive cylinder 6 moves, the rack 7 contacts the gear 8 and the gear 8 rotates, the rotating seat 4 rotates from a horizontal state to an inclined or vertical state, the first lifting drive 11 starts again, the detection end of the hardness tester 14 contacts one side of the cured paint, the first lifting drive 11 continues to move, observe and record the pressure detection value of the pressure sensor 15, when the cured paint detaches from the substrate plate 5, the action stops, the maximum value detected by the pressure sensor 15 during this period is the adhesion force of the paint on the substrate plate 5; the peeled cured paint block is received and transported through the receiving hopper 17 and collected through the open box 18.
