Description

Technical Field

[0001] This invention relates to the field of coating performance testing technology, and in particular to an inorganic coating performance testing device. Background Technology

[0002] Sedimentation and stratification of coatings directly alter their rheological properties. The upper layer, due to reduced powder content, has lower viscosity and excessive fluidity, while the lower layer, due to increased powder content, has higher viscosity, poorer fluidity, and may even clump. This inconsistency in fluidity between the upper and lower layers (i.e., thixotropic differences) severely impacts application quality and coating performance. For example, in spray painting, it may lead to unstable paint output and uneven film thickness; in roller or brush painting, it may result in poor leveling and noticeable brush marks.

[0003] Currently, the industry typically uses the following methods to test coating settling and flowability: Visual inspection: After letting it stand for a period of time, observe whether there is hard sediment at the bottom of the container. This method is highly subjective and cannot quantify the difference in fluidity.

[0004] Sampling comparison method: Samples are taken from the top, middle and bottom of the container respectively, and the viscosity is tested by a rotational viscometer. This method is cumbersome and has a low degree of automation. Summary of the Invention

[0016] The beneficial effects of this invention are as follows: 1.

If there is sedimentation that causes the upper and lower layers of paint to have different flowability, the resistance when the stirring plate rotates will be different, and the detection value of the tension sensor component will also be different.

[0019] 4. By setting up structures such as brush plates and brush heads, this invention allows the baffle to be removed when cleaning is needed. Based on the rotation of the mounting plate, the brush head is used to scrub and clean the inner wall of the container. The cleaning inside the connecting pipe can be achieved by continuously changing the height between the two container tanks to create a height difference, allowing the cleaning water to repeatedly pass through the connecting pipe to achieve the purpose of rinsing.

[0020] 5. By setting up structures such as elastic cylinders and support rings, this invention can utilize the annular folding deformation to match the change in the distance between the end cover and the container when the container is raised and lowered.

Detailed Implementation

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: An inorganic coating performance testing device, such as Figure 1-6 As shown, the device includes a container tank 1 and a first support frame 2. A slide 8 is fixed to the outside of the container tank 1 and slides vertically on the first support frame 2. A height adjustment mechanism for adjusting the height of the container tank 1 is provided between the two container tanks 1. The bottoms of the two container tanks 1 are connected by a connecting structure, and a first control valve 22 for controlling the on / off state is provided on the connecting structure. The container tank 1 is used in conjunction with a detection mechanism, which includes a lifting mechanism. A mounting plate 9 is rotatably mounted on the lifting mechanism. An agitator drive unit for driving the mounting plate 9 to rotate is provided on the lifting mechanism. A center seat 38 is fixed to the bottom of the mounting plate 9. A ring-shaped rotating seat 26 is rotatably mounted on the outer side of the center seat 38. The center seat 38 and the ring-shaped rotating seat 26 are connected by a spiral spring 31. A rotating disk 25 is fixed on the outer side of the ring-shaped rotating seat 26. A tension sensor assembly 29 distributed in a circle is mounted on the top of the mounting disk 9 through a bracket. A through hole 28 is opened on the mounting disk 9. A traction rope 30 is fixed on the rotating disk 25. One end of the traction rope 30 passes through the through hole 28 and is connected to the tension sensor assembly 29. A stirring rod 19 is fixed at the bottom of the rotating disk 25. A mounting cylinder 36 is mounted on the stirring rod 19. A stirring plate 24 is fixed on the side of the mounting cylinder 36. The outer side of the central seat 38 and the inner side of the annular rotating seat 26 are provided with matching annular grooves, and multiple balls 39 are movably installed in the annular grooves. To detect whether sedimentation at the bottom of the coating causes uneven flowability between the upper and lower layers when the coating is left to stand, two adjustable container tanks 1 are installed. During testing, the connecting structure is first closed, and the drone coating is poured into one container 1. After a certain period of time, the connecting structure is opened, allowing the coating at the bottom of container 1 to flow into the other container 1. Based on the principle of communicating vessels, the liquid levels in both containers are level. The connecting structure is then closed again, and an agitator 24 is inserted below the liquid surface. The structure is rotated, and the coating is agitated by the agitator 24. During this process, the annular rotating seat 26 deflects relative to the central seat 38, simultaneously pulling the traction rope 30. The corresponding tension is detected by various tension sensor components 29. Since the coating flowing into the second container 1 is the same coating from the bottom area of ​​the first container 1, if sedimentation causes uneven flowability between the upper and lower layers, the resistance of the agitator 24 during rotation will be different, and the detection values ​​of the tension sensor components 29 will also be different. The flowability of the coating can be judged based on the detection values ​​fed back by the tension sensor components 29.

[0026] To facilitate structural connectivity; such as Figure 3 As shown, the connecting structure includes a connecting pipe 3, a second support frame 5 is provided between the two receiving tanks 1, the connecting pipe 3 is fixed on the second support frame 5, the two ends of the connecting pipe 3 are bent upward to form a U-shaped structure, an end plate 23 is fixed on the top of the connecting pipe 3, a connecting cylinder 20 is fixed on the bottom of the receiving tank 1, and the end plate 23 is slidably connected to the inner wall of the connecting cylinder 20; a first control valve 22 is provided on the connecting pipe 3 to control the opening and closing of the connecting pipe 3.

[0027] To facilitate control of the height of container 1; such as Figure 1 , Figure 2 As shown, the height adjustment mechanism includes a rotating rod 18, which is rotatably mounted on a second support frame 5. A swing drive motor is mounted on one side of the second support frame 5, and a swing drive gear 17 is mounted on the output end of the swing drive motor. A swing driven gear 16 is mounted on the end of the rotating rod 18, and the swing drive gear 17 meshes with the swing driven gear 16. A mounting shaft is fixed on the slide 8, and symmetrically arranged swing frames 6 are fixed on the side of the rotating rod 18. A swing rod 7 is slidably connected to the end of the swing frame 6, and the end of the swing rod 7 is rotatably connected to the mounting shaft of the slide 8. By setting up structures such as the swing frame 6 and the swing rod 7, the swing frame 6 can be driven to shift its angle based on the rotation of the rotating rod 18, thereby raising one side of the swing rod 7 and lowering the other side of the swing rod 7, thereby controlling the corresponding container 1 to rise or fall under the guidance of the first support frame 2; achieving the purpose of adjusting the relative height of the container 1; and controlling the flow of paint from one container 1 to another container 1 by adjusting the relative height of the two container 1.

[0028] To facilitate control of structural lifting; such as Figure 2 As shown, the lifting mechanism includes a guide bracket 11, on which a lifting control motor 12 is mounted. A lifting frame 10 is slidably connected to the inner side of the top of the guide bracket 11. A lifting control screw 13 is mounted on the output end of the lifting control motor 12. The lifting control screw 13 is threadedly connected to the inner wall of the lifting frame 10, and the top of the lifting control screw 13 is rotatably mounted on the guide bracket 11. The mounting plate 9 is rotatably mounted on the lifting frame 10 via a shaft. The agitation drive unit includes an agitation drive motor 15, which is mounted on the lifting frame 10. An agitation drive gear is mounted on the output end of the agitation drive motor 15, and the agitation drive gear meshes with the agitation driven gear 14.

[0029] For better detection; such as Figure 4 As shown, a guide frame 27 is fixed on the top of the mounting plate 9. The top of the guide frame 27 has a circular structure, and the inner ring surface edge of the circular structure is an arc surface structure. The top and bottom edges of the through-hole 28 are provided with arc-shaped edges; the traction rope 30 passes through the guide frame 27. By setting up structures such as the guide frame 27, the traction rope 30 can be guided better, avoiding structural jamming and improving the detection effect.

[0030] To facilitate adjustment of the position of the stirring plate 24; such as Figure 4 As shown, the mounting cylinder 36 is slidably mounted on the outside of the stirring rod 19, and a fastening knob 37 for fixing the mounting cylinder 36 is threadedly connected to one side of the mounting cylinder 36. By setting up structures such as the fastening knob 37, the position of the mounting cylinder 36 on the stirring rod 19 can be adjusted according to the needs, and then fixed by the fastening knob 37, so as to achieve the purpose of adjusting the position of the stirring plate 24.

[0031] To facilitate the removal of paint; such as Figure 3 As shown, the bottom of the connecting pipe 3 is connected to the discharge pipe 4, and a second control valve 21 for controlling the opening and closing of the discharge pipe 4 is provided on the discharge pipe 4.

[0032] To facilitate cleaning the inner wall of container 1; such as Figure 4As shown, the stirring plate 24 has a cavity with an opening at the end away from the mounting cylinder 36. A brush plate 34 is slidably mounted inside the cavity, and a spring 35 is installed between the brush plate 34 and one end of the cavity. A brush head 32 is provided on the side of the brush plate 34 away from the mounting cylinder 36. A baffle 33 for sealing the cavity is detachably mounted at the end of the stirring plate 24 away from the mounting cylinder 36. A support column is provided on the side of the baffle 33 near the brush plate 34. When the baffle 33 is installed at the end of the stirring plate 24, the support column can completely press the brush plate 34 back into the cavity. When the baffle 33 is removed and the stirring plate 24 is located inside the container 1, the brush plate 34 extends out of the outside of the stirring plate 24 based on the support of the spring 35, and the brush head 32 contacts the inner wall of the container 1. By setting up structures such as brush plate 34 and brush head 32, when cleaning is required, the baffle 33 can be removed, and the brush head 32 can be used to scrub and clean the inner wall of the container tank 1 based on the rotation of the mounting plate 9. The cleaning inside the connecting pipe 3 can be achieved by continuously changing the height between the two container tanks 1 to create a height difference, so that the cleaning water repeatedly passes through the connecting pipe 3 to achieve the purpose of rinsing.

[0033] Example 2: An inorganic coating performance testing device, such as Figure 6 As shown, in order to better coordinate the lifting and lowering of the container 1, this embodiment makes the following improvements based on embodiment 1: the connecting structure is replaced with a connecting pipe 3, an elastic cylinder 40 and an end cover 44. The end cover 44 is fixed to the end of the connecting pipe 3. The two ends of the elastic cylinder 40 are respectively connected to the top of the end cover 44 and the bottom of the container 1. The elastic cylinder 40 is provided with annular folds evenly distributed in the vertical direction. When the container 1 moves, the elastic cylinder 40 adapts to the change in the distance between the end cover 44 and the container 1 based on the deformation of the annular folds. The elastic cylinder 40 is provided with a plurality of support rings 41, and the diameter of the support rings 41 is adapted to the size of the corresponding position of the annular folds distributed thereon. By setting up structures such as the elastic cylinder 40 and the support ring 41, the ring-shaped folding deformation can be used to match the change in the distance between the end cover 44 and the container 1 when the container 1 is raised and lowered. The support ring 41 can support the shape of the elastic cylinder 40, ensuring the strength of the structure and avoiding excessive deformation. Compared with embodiment 1, this method can make the up and down movement of the container 1 smoother.

[0034] To avoid structural skewing; such as Figure 6 As shown, the end cover 44 is fixed with circumferentially distributed uprights 43, and the bottom of the receiving tank 1 is fixed with a sleeve 42. The sleeve 42 is slidably connected to the outer wall of the uprights 43. Multiple uprights 43 and sleeves 42 are arranged in a circumferential distribution along the outer side of the elastic cylinder 40. By setting the sleeve 42 and the upright 43, the elastic cylinder 40 can be constrained to a certain extent, thus preventing excessive bending and deformation of the structure.
