However, the required cooling time varies and is unknown for different types of silica gel. Therefore, a silica gel viscosity characteristic test platform is needed to detect and determine the cooling time pattern of silica gel with different compositions.

When the humidity in the external environment of the device is high, it will further lead to errors in the test results. Therefore, it is necessary to improve the silica gel viscosity characteristic test platform to solve the above problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 - Figure 7This utility model provides an embodiment of a silicone viscosity characteristic testing platform, including a device housing 1, an air inlet grille 21, and a testing mechanism. A support leg 4 is fixedly connected to the bottom of the device housing 1. A rotating door 5 is rotatably connected inside the device housing 1. A display screen 6 is installed inside the device housing 1. The testing mechanism is also installed inside the device housing 1. The air inlet grille 21 is fixedly connected inside the device housing 1. A first fixed housing 22 is fixedly connected to the back of the device housing 1. A first connecting pipe 23 is fixedly connected between the first fixed housing 22 and the air inlet grille 21. A suction fan body 24 is installed inside the first connecting pipe 23. A first motor 25 is fixedly connected to the top of the first fixed housing 22. A rotating disk 26 is fixedly connected to the output end of the first motor 25. The rotating disk 26 is rotatably connected inside the first fixed housing 22. An absorbent cotton body 27 is installed on the outside of the first fixed housing 22. The suction fan body 24... Air from inside the device housing 1 is drawn into the first fixed housing 22 and dehumidified by the absorbent cotton body 27. During use, different types of silica gel are extracted and their viscosity is tested by a testing mechanism, and the values ​​are displayed on the display screen 6 to obtain the time data for different silica gel components to cool to the required viscosity within a certain period of time. During testing, the suction fan body 24 provides suction, causing air from inside the device housing 1 to be drawn into the first fixed housing 22 through the air intake grille 21 and the first connecting pipe 23. At the same time, the first motor 25 drives the rotating disk 26 to rotate, and the absorbent cotton body 27 dehumidifies the air to prevent high humidity from affecting the testing mechanism. The first fixed housing 22 has a rotating groove at the relative position of the rotating disk 26. The rotating disk 26 is rotatably connected to the inside of the rotating groove. The rotating groove restricts the rotation of the rotating disk 26 to prevent it from deflecting and affecting the dehumidification of the air by the absorbent cotton body 27.

[0027] Please see Figure 1 - Figure 5In this embodiment, a second fixed housing 28 is fixedly connected to the back of the device housing 1, and a first fixed housing 22 is fixedly connected to the top of the second fixed housing 28. A pull-out plate 29 is slidably connected inside the second fixed housing 28. A pre-filter plate 210, a dust filter plate 211, and an activated carbon filter plate 212 are disposed inside the pull-out plate 29. An exhaust grille 213 is fixedly connected inside the device housing 1. The exhaust grille 213 is connected to the second fixed housing 28. A second connecting pipe 214 is fixedly connected between the outer casings 28. An exhaust fan body 215 is housed inside the second connecting pipe 214. A first threaded rod 216 is rotatably connected inside the pull-out plate 29. A sliding plate 217 is threadedly connected to the outside of the first threaded rod 216. A fixed plate 218 is fixedly connected to the inner side of the pull-out plate 29. A snap-fit ​​rod 219 is fixedly connected to the bottom of the sliding plate 217, snapping into the inside of the fixed plate 218. The exhaust fan body 215 is connected to the pre-filter plate 210, dust filter plate 211, and activated carbon filter plate 218. The carbon filter plate 212 removes dust from the dehumidified air, preventing dust from affecting the silica gel viscosity test. Three pull-out plates 29 are provided, sequentially slidably connected to the inside of the second fixed housing 28 (top, middle, and bottom). The pre-filter plate 210, dust filter plate 211, and activated carbon filter plate 212 are respectively located inside the three pull-out plates 29. By pulling out the corresponding pull-out plates 29, it is easy to access the pre-filter plate 210, dust filter plate 211, and activated carbon filter plate 212. For cleaning and replacement, the pull-out plate 29 has a groove at the opposite position of the sliding plate 217. The sliding plate 217 is slidably connected inside the groove. The groove restricts the sliding of the sliding plate 217, allowing it to slide linearly inside the pull-out plate 29. The fixing plate 218 has a slot at the opposite position of the locking rod 219. The locking rod 219 is locked inside the slot. The slot and the locking rod 219 cooperate to restrict and fix the filter plate inside the pull-out plate 29, while facilitating its subsequent disassembly, cleaning and replacement.

[0028] Please see Figure 2 , Figure 6 - Figure 7In this embodiment, the detection mechanism includes a detection platform 31, which is fixedly connected inside the device housing 1. A bidirectional threaded rod 32 is rotatably connected inside the detection platform 31. A knob 33 is fixedly connected to the outside of the bidirectional threaded rod 32. A sliding block 34 is threadedly connected to the outside of the bidirectional threaded rod 32 and slidably connected inside the detection platform 31. A clamping plate 35 is fixedly connected to the inner side of the sliding block 34. A measuring cup 36 is provided on the top of the detection platform 31. A guide rail 37 is fixedly connected to the top of the detection platform 31. A second motor 38 is fixedly connected to the top of the guide rail 37. A second threaded rod 39 is fixedly connected to the output end of the second motor 38 and rotatably connected inside the guide rail 37. A connecting rod 310 is threadedly connected to the outside of the guide rail 37 and slidably connected inside the guide rail 37. A third motor 311 is fixedly connected to the top of the connecting rod 310, and a knob 33 is fixedly connected to the output end of the third motor 311. The rotor 312 is rotatably connected inside the connecting rod 310. A turntable 313 is rotatably connected to the outside of the rotor 312. A controller body 314 is provided on the right side of the connecting rod 310. The controller body 314 is a PLC controller. In actual use, the controller body 314 analyzes the test results and displays them on the display screen 6. The detection platform 31 has a groove at the relative position of the sliding block 34. The sliding block 34 is slidably connected inside the groove. The groove restricts the sliding of the sliding block 34, making it slide linearly inside the sliding block 34. The clamping plate 35 restricts the measuring cup 36 to be centered. The guide rail 37 has a groove at the relative position of the connecting rod 310. The connecting rod 310 is slidably connected inside the groove. The groove restricts the sliding of the connecting rod 310, making it slide linearly inside the guide rail 37. Then, the third motor 311 works to detect the viscosity of the silicone through the rotor 312 and the turntable 313.

[0029] During operation, various types of silica gel are transported from the reactor via a Teflon conveyor belt, allowing for static cooling. A small portion is extracted and placed into a measuring cup 36, positioned between clamping plates 35. Rotating knob 33 causes the bidirectional threaded rod 32 to rotate, sliding block 34 inwards. The clamping plates 35 contact the measuring cup 36, ensuring its centered position. Turning door 5 closes, and the second motor 38 drives the connecting rod 310 downwards via the second threaded rod 39. The third motor 311 then drives the turntable 313 and rotor 312, stirring the silica gel inside the measuring cup 36. The controller 314 analyzes the data, displaying it on screen 6 to check if the viscosity of the extracted silica gel sample meets the standard. Repeated testing is performed, simultaneously monitoring temperature and tensile strength. After prolonged operation, temperature-viscosity (tensile strength) curves and time-viscosity (tensile strength) curves are obtained. Based on the experimental data, the cooling time patterns of different silica gel compositions are determined. Temperature monitoring is a commonly used technique. The method is not described in detail here. While the rotating door 5 is closed for testing, the suction fan 24 operates, allowing air to pass through the air intake grille 21 and the first connecting pipe 23 before entering the first fixed housing 22. Then, the first motor 25 operates, driving the rotating disc 26 and the absorbent cotton body 27 to rotate. The absorbent cotton body 27 absorbs the moisture in the air, and the exhaust fan 215 operates, dehumidifying the air inside the first fixed housing 22 before it passes through the second fixed housing 28, the second connecting pipe 214, and the exhaust grille 21. 3. The air is returned to the device housing 1. Inside the second fixed housing 28, the air passes through three layers of pull-out plates 29 and their corresponding pre-filter plate 210, dust filter plate 211 and activated carbon filter plate 212 to remove dust and prevent dust from affecting the final test results. When the filter plate needs to be replaced later, pull out the corresponding pull-out plate 29, rotate the first threaded rod 216 to drive the sliding plate 217 to slide, so that the locking rod 219 is disengaged from the fixed plate 218, and then the filter plate can be taken out for cleaning and replacement.

[0030] By adding the first fixed housing 22, the suction fan body 24, the first motor 25, the rotating disk 26, and the water-absorbing cotton body 27, the problem that the water absorption of silicone will cause it to absorb moisture from the air, and that the final test results will be affected when the humidity in the environment is high, can be solved by adding the first fixed housing 22, the suction fan body 24, the first motor 25, the rotating disk 26, and the water-absorbing cotton body 27.
