Description

Technical Field

[0001] This invention relates to the field of MS sealant testing, and more particularly to an MS sealant extreme condition simulation device and testing method. Background Technology

[0002] MS sealant is a new generation of building sealing material, widely used in bonding, filling, sealing, waterproofing, and reinforcement in building engineering and decoration. Especially in prefabricated buildings, it effectively prevents cracking caused by high internal stress, improving durability.

[0003] When applying MS sealant, specifications recommend application within a temperature range of 4–40℃ to ensure effective adhesion. However, due to project timelines, many projects must be applied in winter environments of -3–5℃. Currently, most domestically produced MS sealant products achieve the expected adhesion results. However, the adhesion performance of assembled MS sealant in winter environments of -10℃ needs further verification. In regions like Northeast my country, winter outdoor temperatures can even reach -20℃ to -30℃. Therefore, it is necessary to test the adhesion performance of MS sealant under various cold conditions. Existing testing methods typically involve placing the MS sealant in a cold storage facility to simulate actual cold conditions, thereby testing its adhesion performance. However, this method is costly and often requires workers to enter the cold storage for testing, which can cause health problems and discomfort for workers due to prolonged exposure to cold conditions. Therefore, we propose an extreme condition simulation device and testing method for MS sealant. Summary of the Invention

[0004] To address the technical problem that existing MS sealant testing often requires workers to enter cold storage for testing, which can cause health damage to workers due to prolonged exposure to cold storage conditions, this invention provides an MS sealant extreme condition simulation device and testing method.

[0005] This invention is achieved using the following technical solution: an MS sealant extreme condition simulation device, comprising a simulation device assembly, the simulation device assembly including a bidirectional reciprocating movement mechanism; a tensioning and separation mechanism; a refrigeration simulation mechanism for simulating freezing environments; and a cleaning mechanism for cleaning MS sealant.

[0006] The bidirectional reciprocating moving mechanism includes a motor mounting plate, a moving gear connected below the motor mounting plate, a bidirectional rack meshing with the outer side of the moving gear, the bidirectional rack being engaged in a limiting groove, a mounting rod connected to the bottom end of the bidirectional rack, the mounting rod being connected to the sub-telescopic rod, and the sub-telescopic rod being inserted into the inner side of the main telescopic rod.

[0007] The opening and closing mechanism includes a receiving seat mounted on a movable plate. The bottom end of the receiving seat is connected to a sliding rack, which is set in a sliding groove. A rotating gear is installed inside the sliding groove. An adjustment groove is opened on the surface of the movable plate. A transverse frame is attached to the bottom end of the movable plate. A limit block extends above the transverse frame and is engaged in the adjustment groove in the movable plate. A moving component is connected to one end of the transverse frame. The moving component slides inside the moving groove. A fixed block is connected above the moving component, and a closing plate is connected above the fixed block.

[0008] The refrigeration simulation mechanism includes a connecting rod, the bottom end of which is connected to a rotating gear, and a main gear sleeved on the top surface of the connecting rod. The connecting rod passes through a mounting plate, and an eccentric gear meshes with the outer side of the main gear. A first shaft is mounted on the surface of the eccentric gear. One end of the moving shaft is connected to the first shaft, and the other end is connected to a second shaft. The second shaft is mounted on a swing rod, and one end of the swing rod is provided with a rotating shaft, which is connected to a rotating shaft seat. The other end of the swing rod is connected to a refrigerator.

[0009] The cleaning mechanism includes a rotating disk, a first adjusting shaft connected to the surface of the rotating disk, one end of an adjusting shaft connected to the first adjusting shaft, the other end of the adjusting shaft connected to a second adjusting shaft, the second adjusting shaft mounted on the top of a moving rod, the bottom end of the moving rod connected to the inside of a transverse groove, a connecting sleeve fitted onto the surface of the moving rod, a cleaning rod movably connected to the outside of the connecting sleeve, and a cleaning brush connected to the cleaning rod.

[0010] As a further improvement to the above scheme, the sub-telescopic rod is inserted into the main telescopic rod, slides inside the main telescopic rod, and one end of the sub-telescopic rod is connected to the receiving seat in the opening and closing separation mechanism.

[0011] As a further improvement to the above solution, four sets of merging plates are provided. The four sets of merging plates are joined together to form a circumference. A sealing part is provided at the connection between adjacent merging plates, and MS sealing adhesive is applied to the sealing part.

[0012] As a further improvement to the above scheme, the sub-telescopic rod drives the connected receiving seat to reciprocate laterally. The bidirectional reciprocating movement mechanism can drive the opening and closing separation mechanism set on both sides to move synchronously, so as to realize the synchronous movement of the two sets of opening and closing separation mechanisms and ensure the synchronicity of the work.

[0013] As a further improvement to the above scheme, the tensioning and separation mechanism is provided in two sets, which are located at both ends of the bidirectional reciprocating moving mechanism. The bidirectional reciprocating moving mechanism drives the two sets of bidirectional reciprocating moving mechanisms to move synchronously.

[0014] As a further improvement to the above solution, the fixing block pulls the closing plates to separate them. By observing how long it takes for the closing plates to separate under external force when they are sealed with MS sealant, the adhesive force of MS sealant under different cold conditions can be known.

[0015] As a further improvement to the above solution, the reciprocating swing of the connected cooler is driven by the swing rod, and the cooler sprays out cooling gas to ensure uniform spraying of cold air. The temperature of the cold air sprayed by the cooler can be controlled and adjusted according to the actual situation. By spraying cooling gas through the reciprocating swing of the cooler, the cold air reaches the sealing part to simulate the cold weather outside, so as to facilitate the subsequent measurement of the adhesion force of MS sealant in cold weather.

[0016] As a further improvement to the above solution, the excess MS sealant dripping from the sealing part is cleaned by the lateral oscillation of the cleaning brush, preventing excess MS sealant from dripping to the bottom and avoiding adhesion of the mechanical structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention innovatively proposes a refrigeration simulation mechanism and a cleaning mechanism. The two mechanisms are closely connected together. When the refrigeration simulation mechanism is working, the refrigerator reciprocates and oscillates. When the refrigerator sprays out refrigeration gas, the cleaning mechanism also works synchronously. The cleaning brush in the cleaning mechanism also reciprocates and oscillates synchronously. The cleaning brush cleans the excess MS sealant dripping from the sealing part, preventing excess MS sealant from dripping to the bottom and avoiding adhesion of the mechanical structure. The two mechanisms are closely connected to ensure the synchronicity of operation.

[0019] 2. The bidirectional reciprocating moving mechanism, the opening and closing separation mechanism, the refrigeration simulation mechanism, and the cleaning mechanism of this invention are interconnected. The synchronous operation of all mechanisms can be achieved solely through the operation of the motor in the motor mounting plate of the bidirectional reciprocating moving mechanism. The four sets of mechanisms are linked together to ensure the compactness and synchronicity of the structural operation, and also save costs. By observing how long it takes for the closing plate to separate under external force when it is sealed with MS sealant, the adhesion force of MS sealant under different cold conditions can be known, thus realizing the detection of the adhesion effect of MS sealant under cold conditions.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1:

[0035] Please combine Figures 1-5 This embodiment proposes an MS sealant extreme condition simulation device, including a simulation device assembly 1, which includes a bidirectional reciprocating movement mechanism 2; a tensioning and separation mechanism 3; a refrigeration simulation mechanism 4 for simulating freezing environments; and a cleaning mechanism 5 for cleaning MS sealant.

[0036] The bidirectional reciprocating moving mechanism 2 includes a motor mounting plate 21. A motion gear 22 is connected to the lower part of the motor mounting plate 21. A bidirectional rack 23 meshes with the outer side of the motion gear 22. The bidirectional rack 23 is engaged in the limiting groove block 24. A mounting rod 25 is connected to the bottom end of the bidirectional rack 23. The mounting rod 25 is connected to the sub-telescopic rod 26. The sub-telescopic rod 26 is inserted into the inner side of the main telescopic rod 27.

[0037] It should be noted that the sub-telescopic rod 26 is inserted into the main telescopic rod 27, and the sub-telescopic rod 26 slides inside the main telescopic rod 27. One end of the sub-telescopic rod 26 is connected to the receiving seat 31 in the opening and closing separation mechanism 3.

[0038] More specifically, when the closing plates 312 are closed, the worker drips MS sealant into the sealing part 313 between adjacent closing plates 312 and smooths it out. Then, the motor inside the motor mounting plate 21 drives the motion gear 22 connected below it to rotate. The motion gear 22 drives the bidirectional rack 23 that meshes with it to move. The bidirectional rack 23 then slides inside the limiting groove block 24. As the bidirectional rack 23 moves, the mounting rod 25 connected to the bidirectional rack 23 is driven to move synchronously. The mounting rod 25 drives the sub-telescopic rod 26 to extend and retract inside the main telescopic rod 27. The sub-telescopic rod 26 then drives the receiving seat 31 connected to it to reciprocate laterally. The bidirectional reciprocating movement mechanism 2 can then drive the opening and closing separation mechanism 3 set on both sides to move synchronously, realizing the synchronous movement of the two sets of opening and closing separation mechanisms 3 and ensuring the synchronicity of the work.

[0039] Furthermore, the tensioning and separating mechanism 3 is provided in two sets, which are located at both ends of the bidirectional reciprocating moving mechanism 2. The bidirectional reciprocating moving mechanism 2 drives the two sets of bidirectional reciprocating moving mechanisms 2 to move synchronously.

[0040] The opening and closing separation mechanism 3 includes a receiving seat 31, which is mounted on a movable plate 32. The bottom end of the receiving seat 31 is connected to a sliding rack 33, which is disposed in a sliding groove 34. A rotating gear 35 is disposed inside the sliding groove 34. An adjustment groove 36 is provided on the surface of the movable plate 32. A transverse frame 37 is attached to the bottom end of the movable plate 32. A limit block 38 extends above the transverse frame 37 and is engaged in the adjustment groove 36 in the movable plate 32.

[0041] One end of the transverse frame 37 is connected to a movable component 39, which slides inside the movable groove 310. A fixed block 311 is connected above the movable component 39, and a closing plate 312 is connected above the fixed block 311.

[0042] It should be further explained that there are four sets of closing plates 312. The four sets of closing plates 312 are closed to form a circumference. A sealing part 313 is provided at the connection between adjacent closing plates 312. MS sealing adhesive is applied to the sealing part 313.

[0043] More specifically, while the receiving seat 31 is moved by the telescopic rod 26, the receiving seat 31 simultaneously moves the movable plate 32 connected below it. As the movable plate 32 moves laterally, the adjustment groove 36 on the surface of the movable plate 32 moves the limiting block 38 synchronously. The limiting block 38 then moves the transverse frame 37 below it. The transverse frame 37 then moves the moving component 39 inside the moving groove 310. The moving component 39 then pulls the fixed block 311 connected above it to move synchronously. The fixed block 311 then moves the closing plate 312, pulling the closing plates 312 apart. By observing how long it takes for the closing plate 312 to separate under external force when it is sealed with MS sealant, the adhesive force of MS sealant under different cold conditions can be known.

[0044] Example 2:

[0045] Please combine Figures 6-8 Example 2 further proposes a refrigeration simulation mechanism 4 and a cleaning mechanism 5. Both the refrigeration simulation mechanism 4 and the cleaning mechanism 5 are provided in two sets, which are symmetrically installed at both ends of the simulation device 1.

[0046] The refrigeration simulation mechanism 4 includes a connecting rod 41, the bottom end of which is connected to a rotating gear 35, and a main gear 43 sleeved on the top surface of the connecting rod 41. The connecting rod 41 passes through a mounting plate 42. An eccentric gear 44 meshes with the outer side of the main gear 43. A first shaft 45 is mounted on the surface of the eccentric gear 44. One end of the moving shaft 46 is connected to the first shaft 45, and the other end is connected to a second shaft 47. The second shaft 47 is mounted on a swing rod 48. One end of the swing rod 48 is provided with a rotating shaft 49, which is connected to a rotating shaft seat 410. The other end of the swing rod 48 is connected to a cooler 411.

[0047] More specifically, as the receiving seat 31 is driven by the telescopic rod 26, the receiving seat 31 then drives the sliding rack 33 connected to its bottom end to slide inside the sliding groove 34. As the sliding rack 33 slides, it drives the rotating gear 35 meshing with it to rotate. The connecting rod 41 connected to the top of the rotating gear 35 is then driven to rotate synchronously. The main gear 43 sleeved on the surface of the top of the connecting rod 41 is driven to rotate synchronously.

[0048] As the main gear 43 rotates, it drives the two sets of eccentric gears 44 meshing with it to rotate synchronously. The first shaft 45 connected to the surface of the eccentric gear 44 is driven to reciprocate. The moving shaft 46 connected to the outside of the first shaft 45 is driven to move synchronously. The second shaft 47 connected to the other end of the moving shaft 46 is driven to move synchronously. The second shaft 47 then drives the swing rod 48 connected to it to reciprocate and swing. The rotating shaft 49 at the bottom of the swing rod 48 deflects with the rotating shaft seat 410 as the base point. The swing rod 48 thus drives the refrigerator 411 connected to it to reciprocate and swing. The refrigerator 411 sprays out cooling gas to ensure uniform spraying of cold gas. The temperature of the cold gas sprayed by the refrigerator 411 can be controlled and adjusted according to the actual situation. By spraying cooling gas through the reciprocating swing of the refrigerator 411, the cold gas reaches the sealing part 313 to simulate the cold weather outside, so as to facilitate the subsequent measurement of the adhesion force of MS sealant in cold weather.

[0049] It should be noted that the top end of the connecting rod 41 is connected to the rotating disk 51 in the cleaning mechanism 5, and the rotating rod 41 drives the rotating disk 51 to rotate synchronously while rotating.

[0050] The cleaning mechanism 5 includes a rotating disk 51, a first adjusting shaft 52 connected to the surface of the rotating disk 51, one end of an adjusting shaft 53 connected to the first adjusting shaft 52, and the other end of the adjusting shaft 53 connected to a second adjusting shaft 54. The second adjusting shaft 54 ​​is installed at the top of a moving rod 55, the bottom end of the moving rod 55 is connected to the inside of a transverse groove 56, a connecting bushing 57 is sleeved on the surface of the moving rod 55, a cleaning rod 58 is movably connected to the outside of the connecting bushing 57, and a cleaning brush 59 is connected to the cleaning rod 58.

[0051] Specifically, as the connecting rod 41 rotates, the rotating disk 51 connected to the top of the connecting rod 41 rotates synchronously, and the first adjusting shaft 52 connected to the surface of the rotating disk 51 moves synchronously. The first adjusting shaft 52 then drives the adjusting shaft 53 to swing synchronously, and the adjusting shaft 53 drives the second adjusting shaft 54 ​​connected to it to move synchronously. The moving rod 55 connected below the second adjusting shaft 54 ​​is then driven to slide inside the transverse groove 56, and the moving rod 55 moves back and forth laterally. As the moving rod 55 moves back and forth laterally, it drives the connecting bushing 57 and the cleaning rod 58 connected to it to move. The cleaning rod 58 drives the cleaning brush 59 connected to it to swing back and forth laterally. As the cleaning brush 59 swings laterally, it cleans the excess MS sealant dripping from the sealing part 313, preventing excess MS sealant from dripping down and avoiding adhesion of the mechanical structure.

[0052] Specific implementation steps of the overall technical solution of this invention:

[0053] In use, when the closing plates 312 are closed, the operator applies MS sealant to the sealing part 313 between adjacent closing plates 312 and smooths it out. Then, the operation of the motor inside the motor mounting plate 21 drives the motion gear 22 connected below it to rotate. The motion gear 22 drives the bidirectional rack 23 meshing with it to move. The bidirectional rack 23 then slides inside the limiting groove block 24. As the bidirectional rack 23 moves, the mounting rod 25 connected to the bidirectional rack 23 is driven to move synchronously. The mounting rod 25 drives the sub-telescopic rod 26 to extend and retract inside the main telescopic rod 27. The sub-telescopic rod 26 then drives the receiving seat 31 connected to it to reciprocate laterally. The bidirectional reciprocating movement mechanism 2 can then drive the opening and closing separation mechanism 3 set on both sides to move synchronously, realizing the synchronous movement of the two sets of opening and closing separation mechanisms 3 and ensuring the synchronicity of the work.

[0054] As the receiving seat 31 is driven by the telescopic rod 26, the receiving seat 31 then drives the sliding rack 33 connected to its bottom end to slide inside the sliding groove 34. As the sliding rack 33 slides, it drives the rotating gear 35 meshing with it to rotate. The connecting rod 41 connected to the top of the rotating gear 35 is then driven to rotate synchronously. The main gear 43 sleeved on the surface of the top of the connecting rod 41 is driven to rotate synchronously. As the main gear 43 rotates, it then drives the two sets of eccentric gears 44 meshing with it to rotate synchronously. The first shaft 45 connected to the surface of the eccentric gear 44 is driven to reciprocate. The moving shaft 46 connected to the outside of the first shaft 45 is driven to move forward. The second shaft 47, connected to the other end of the moving shaft 46, is driven to move synchronously. The second shaft 47 then drives the swing rod 48 connected to it to swing back and forth. The rotating shaft 49 at the bottom of the swing rod 48 deflects with the rotating shaft seat 410 as the base point. The swing rod 48 thus drives the refrigerator 411 connected to it to swing back and forth. The refrigerator 411 sprays out cooling gas to ensure uniform spraying of cold gas. The temperature of the cold gas sprayed by the refrigerator 411 can be controlled and adjusted according to the actual situation. By spraying cooling gas through the reciprocating swing of the refrigerator 411, the cold gas reaches the sealing part 313 to simulate the cold weather outside, so as to facilitate the subsequent measurement of the adhesion force of MS sealant in cold weather.

[0055] As the connecting rod 41 rotates, the rotating disk 51 connected to the top of the connecting rod 41 rotates synchronously, and the first adjusting shaft 52 connected to the surface of the rotating disk 51 moves synchronously. The first adjusting shaft 52 then drives the adjusting shaft 53 to swing synchronously, and the adjusting shaft 53 drives the second adjusting shaft 54 ​​connected to it to move synchronously. The moving rod 55 connected below the second adjusting shaft 54 ​​is then driven to slide inside the transverse groove 56, and the moving rod 55 moves back and forth. As the moving rod 55 moves back and forth, it drives the connecting bushing 57 and the cleaning rod 58 connected to it to move. The cleaning rod 58 drives the cleaning brush 59 connected to it to swing back and forth. As the cleaning brush 59 swings back and forth, it cleans the excess MS sealant dripping from the sealing part 313, preventing excess MS sealant from dripping down and avoiding adhesion of the mechanical structure.

[0056] Simultaneously, as the aforementioned receiving seat 31 moves with the telescopic rod 26, the receiving seat 31 also moves the movable plate 32 connected below it. As the movable plate 32 moves laterally, the adjustment groove 36 on the surface of the movable plate 32 moves the limiting block 38 synchronously. The limiting block 38 then moves the transverse frame 37 below it. The transverse frame 37 then moves the moving component 39 inside the moving groove 310. The moving component 39 then pulls the fixed block 311 connected above it to move synchronously. The fixed block 311 then moves the closing plate 312, pulling the closing plates 312 apart. By observing how long it takes for the closing plate 312 to separate under external force when it is sealed with MS sealant, the adhesive force of MS sealant under different cold conditions can be known.

[0057] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
