Description

Technical Field

[0001] This utility model belongs to the field of gypsum putty powder testing technology, specifically referring to a gypsum putty powder adhesion testing device. Background Technology

[0002] Gypsum putty powder is a common building material used to repair and level surfaces such as walls and ceilings. It typically consists of gypsum, fillers, adhesives, and other additives. During the production of gypsum putty powder, its adhesion needs to be tested to ensure product quality. Traditional methods for testing gypsum putty powder adhesion involve applying the powder to a substrate to create a sample, then tapping or pressing it to cause the powder to peel off, thus determining the adhesion strength.

[0003] Traditional testing devices can only perform compression testing or impact testing separately, and cannot carry out these two testing modes simultaneously. This makes it difficult to comprehensively and accurately evaluate the adhesion performance of gypsum putty powder in real-world application scenarios, and cannot provide comprehensive and reliable data support for the optimization, improvement, and practical application of gypsum putty powder. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a gypsum putty powder adhesion testing device, which effectively solves the problem that the existing testing devices cannot carry out two testing modes at the same time.

One end of the connecting rod is hinged to one end of the rotating plate, and the other end of the connecting rod is hinged to the fixing block.

[0008] Preferably, the fixing mechanism includes a chute, a bidirectional lead screw, a moving frame and a fixing frame. The chute is arranged on the base. The bidirectional lead screw is rotatably arranged in the chute. Both ends of the bidirectional lead screw extend to both sides of the base.

[0020] like Figure 1-4 As shown, the present invention proposes a gypsum putty powder adhesion testing device, including a base 1, a fixing mechanism 2 on the base 1, and a compression testing mechanism 3 and a striking testing mechanism 4 above the fixing mechanism 2 on the base 1. The compression testing mechanism 3 includes a cylinder 5, a support frame 6, and a pressure block 7. The support frame 6 is fixed on the base 1, the cylinder 5 is fixed on the top of the support frame 6, a pressure sensor 12 is installed at the movable end of the bottom of the cylinder 5, and the pressure block 7 is fixedly installed below the pressure sensor 12. The striking testing mechanism 4 includes a support column 8, a movable top plate 9, and a mounting plate 10. The support column 8 is fixed on the base 1, the movable top plate 9 is slidably disposed on the support column 8, the mounting plate 10 is fixed on the top of the support column 8, a pressure sensor 13 is installed at the bottom of the movable top plate 9, a striking block 11 is fixedly installed below the pressure sensor 13, and a driving structure 28 is provided above the movable top plate 9.

[0021] like Figure 1 , 2 As shown, the drive structure 28 includes a connecting top plate 14, a threaded rod 15, a dual-axis motor 16, a rotating plate 17, a connecting rod 18, and a fixing block 19. The threaded rod 15 is rotatably mounted on the top of the mounting plate 10, and a top block 20 is fixed to the top of the threaded rod 15. The connecting top plate 14 is threadedly connected to the threaded rod 15. A limiting rod 27 is provided on the movable top plate 9, penetrating the connecting top plate 14. The connecting top plate 14 slides relative to the limiting rod 27. The dual-axis motor 16 is mounted on the connecting top plate 14, the rotating plate 17 is fixed to the output end of the dual-axis motor 16, and the fixing block 19 is fixed to the movable top plate 9. At the top, one end of the connecting rod 18 is hinged to one end of the rotating plate 17, and the other end of the connecting rod 18 is hinged to the fixed block 19. The dual-axis motor 16 drives the rotating plate 17 to rotate, the rotating plate 17 drives the connecting rod 18 to rotate, and the connecting rod 18 drives the fixed block 19 and the movable top plate 9 to move up and down reciprocally, thereby driving the striking block 11 to strike the sample block for testing. Rotating the top block 20 drives the threaded rod 15 to rotate, and the threaded rod 15 drives the connecting top plate 14 and the movable top plate 9 to move up and down as a whole. The height of the striking block 11 is adjusted according to the thickness of the gypsum putty powder on different samples.

[0022] like Figure 3 , 4 As shown, the fixing mechanism 2 includes a slide 21, a bidirectional lead screw 22, a movable frame 23, and a fixed frame 24. The slide 21 is mounted on the base 1, and the bidirectional lead screw 22 is rotatably mounted inside the slide 21. Both ends of the bidirectional lead screw 22 extend to both sides of the base 1, and end blocks 25 are fixed to both ends of the bidirectional lead screw 22. The movable frame 23 is threadedly connected to the bidirectional lead screw 22, and the fixed frame 24 is symmetrically mounted on the base 1. Rotating the end blocks 25 drives the bidirectional lead screw 22 to rotate, and the bidirectional lead screw 22 drives the movable frame 23 to move away from each other and closer to the fixed frame 24, thereby fixing the sample block. Both the movable frame 23 and the fixed frame 24 are "U"-shaped structures to increase the stability of the sample block. The movable frame 23 is slidably mounted relative to the slide 21. The longitudinal section of the slide 21 is T-shaped to ensure the stability of the movable frame 23.

[0023] like Figure 2 As shown, the support frame 6 and the movable top plate 9 are both equipped with display screens 26 at their front ends, which are electrically connected to pressure sensor 12 and pressure sensor 23 respectively, displaying the real-time pressure of pressure sensor 12 and pressure sensor 23.

[0024] In practical use, two identical sample blocks that have been pre-coated are placed in the fixed frames 24 on the left and right sides respectively. The rotating end block 25 drives the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 drives the moving frame 23 to move away from each other and closer to the fixed frame 24, thereby fixing the sample blocks. At the same time, the cylinder 5 and the dual-axis motor 16 are started. The cylinder 5 drives the pressure block 7 to press down and squeeze the gypsum putty powder sample. The pressure sensor 12 senses the magnitude of the applied pressure and records the reading when the sample is sheared and broken.

[0025] The dual-axis motor 16 drives the rotating plate 17 to rotate, the rotating plate 17 drives the connecting rod 18 to rotate, the connecting rod 18 drives the fixed block 19 and the movable top plate 9 to move up and down reciprocally, thereby driving the striking block 11 to strike the sample block for testing. The rotating top block 20 drives the threaded rod 15 to rotate, and the threaded rod 15 drives the connecting top plate 14 and the movable top plate 9 to move up and down as a whole. The height of the striking block 11 is adjusted according to the thickness of the gypsum putty powder on different samples. The pressure sensor 13 can measure the impact force generated during the strike in real time and adjust the speed or torque of the dual-axis motor 16 appropriately so that the striking force is kept within the set range.

[0026] The surface of the sample block can be divided into several small areas of equal area, such as 100 small square areas with a side length of 1 cm. After the tapping test, the number of peeling areas is counted and the proportion of peeling area to the total area is calculated. If the peeling area exceeds a certain threshold (such as 50%), it indicates that the putty powder has poor adhesion; if the peeling area is less than 10%, the adhesion is good.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
