Description

Technical Field

[0001] This utility model relates to the technical field of silicone sheet testing equipment, specifically a device for testing the hardness of finished silicone sheets. Background Technology

[0002] Silica gel, also known as silica gel, is a highly active adsorbent material and belongs to the amorphous substance category. The main component of silica gel is silicon dioxide, which is chemically stable and non-flammable. After silica gel is produced, various indicators need to be tested to ensure its quality, with hardness testing being an important indicator. Therefore, a testing instrument is required for this purpose. In response, Chinese utility model patent CN207423653U discloses a hardness tester for silicone, including a base. The base has a first groove at its upper end, and four rectangular second grooves are formed on the bottom wall of the first groove. Each second groove contains a fixing block, and each fixing block has a connecting block at its upper end. The end of the connecting block away from the fixing block extends to the outside of the second groove and is connected to a moving block. The moving block has a moving groove at its end near the connecting block, and one end of the connecting block is inserted into the moving groove. The connecting block, located in the moving groove, has two symmetrically arranged slots at both ends. Each slot contains multiple third springs, and the movable ends of the third springs are connected to a retaining ball. The side wall of the moving block has multiple through holes. This utility model is easy to operate, can test the hardness of silicone, and is inexpensive, making it highly suitable for widespread application. The aforementioned equipment lacks protection for the hardness tester probe, making it highly susceptible to bending or damage due to accidental collisions or scratches during equipment handling, installation, debugging, or sample replacement. To address this issue, we propose a silicone sheet finished product hardness testing device. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please see Figure 1-4 This utility model provides a technical solution: a device for testing the hardness of a finished silicone sheet, including a support platform 1. Please see Figure 1 and Figure 4 The bottom surface of the support platform 1 is symmetrically fixed to the support base 2, the top surface of the support platform 1 is fixed to the support frame 3, the bottom surface of the support frame 3 is provided with an adjustment groove 301, the inner wall of the adjustment groove 301 is provided with a moving groove 302, the moving groove 302 is provided with a fixing component 4, and the fixing component 4 is snapped into the adjustment groove 301. Furthermore, the support frame 3 has an overall L-shaped structure.

[0016] Please see Figure 1 and Figure 2 The support frame 3 has an installation port 303 on its top surface. A cylinder 5 is installed in the installation port 303. The output end of the cylinder 5 is fixed to the top surface of the mounting plate 6. The mounting plate 6 has symmetrical limiting holes 601. A hardness tester 7 is installed on the bottom surface of the mounting plate 6. The hardness tester 7 is located inside the protective enclosure 8. Fixing blocks 9 are symmetrically fixed to both sides of the protective enclosure 8. The top surface of the fixing blocks 9 is respectively fixed to one end of the positioning rod 10 corresponding to the limiting hole 601. The other end of the positioning rod 10 passes through the limiting hole 601 and is fixed to the bottom surface of the limiting block 11. The bottom surface of the limiting block 11 contacts the top surface of the mounting plate 6. The protective enclosure 8 will adjust its position as the hardness tester 7 moves down. Therefore, the protective enclosure 8 will always protect the probe of the hardness tester 7 to prevent it from bending or being damaged due to accidental collision or scratch. Furthermore, the diameter of the positioning rod 10 is adapted to the diameter of the limiting hole 601, and the diameter of the limiting block 11 is larger than the diameter of the limiting hole 601.

[0017] Please see Figure 1 and Figure 3 The protective enclosure 8 is provided with an observation port 801, and a transparent plate 12 is fixed inside the observation port 801. Multiple contact blocks 802 are evenly fixed to the bottom surface of the protective enclosure 8 to avoid the protective enclosure 8 obstructing the hardness tester 7 and making it inconvenient to observe the data.

[0018] Furthermore, the bottom of the contact block 802 has a hemispherical structure, which can reduce the contact area with the silicone plate to be tested and reduce the impact on the test results.

[0019] Example 2: Please see Figure 1 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment; Specifically, the fixing component 4 includes a servo motor 41, which is mounted on the outer wall of the support frame 3. The drive end of the servo motor 41 extends into the moving groove 302 and is fixed to one end of the lead screw 42. The other end of the lead screw 42 is rotatably connected to the inner wall of the moving groove 302. The lead screw 42 is provided with a bidirectional thread. Two moving blocks 43 are symmetrically engaged in the moving groove 302. The moving blocks 43 are provided with moving holes 44. The inner walls of the moving holes 44 are respectively provided with threaded structures and are threadedly engaged with the lead screw 42. The bottom surfaces of the moving blocks 43 are respectively fixed with clamping plates 45. One end of the clamping plate 45 is engaged in the adjusting groove 301. The sides of the two clamping plates 45 that are close to each other are respectively fixed with contact pads 46. The position of the silicone plate to be tested can be limited by adjusting the position of the clamping plates 45 to prevent it from moving during the testing process.

[0020] Furthermore, the length and width of the movable block 43 are adapted to the width and depth of the movable slot 302, respectively.

[0021] Please see Figures 1 to 4In the process of using this utility model, the silicone plate to be tested is placed on the support platform 1, positioned between the clamping plates 45 of the fixing component 4. The controller 13 controls the servo motor 41 to drive the lead screw 42 to rotate, causing the moving block 43 to move the clamping plate 45 through the threaded engagement between the moving hole 44 and the lead screw 42. This ensures that the contact pad 46 contacts both sides of the silicone plate to be tested, preventing movement during the testing process. Then, the cylinder 5 is controlled to drive the mounting plate 6, causing the hardness tester 7 to move down to contact the silicone plate for testing. During the downward movement of the mounting plate 6, the protective enclosure... The bottom of the contact block 802 at the bottom of the test plate first contacts the surface of the silicone plate. The bottom of the contact block 802 has a hemispherical structure, which can reduce the contact area with the silicone plate to be tested and reduce the impact on the test results. The protective plate 8 remains stationary under the engagement of the positioning rod 10 and the limiting hole 601. The transparent plate 12 set on the protective plate 8 can facilitate the observation of the value on the hardness tester 7 while providing protection. After the test is completed, the cylinder 5 drives the mounting plate 6 to move upward. The protective plate 8 will always protect the probe of the hardness tester 7 to prevent it from bending or being damaged due to accidental collision or scratch.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
