Description

Technical Field

[0001] This utility model belongs to the field of materials testing technology, and in particular relates to a high-temperature resistance testing device for silicone products. Background Technology

[0002] As various industries increasingly demand higher performance from silicone products, their high-temperature resistance is becoming increasingly crucial. In practical applications, silicone products may encounter various high-temperature conditions. Insufficient high-temperature resistance can lead to deformation, aging, embrittlement, and loss of elasticity, thus affecting the overall product quality and lifespan, and potentially even causing safety accidents.

[0003] Through prolonged high-temperature testing, this device can simulate the performance evolution of silicone products under long-term high-temperature use conditions, thereby evaluating their high-temperature lifespan. This provides important reference for product design, material selection, and use, helping to optimize the formulation and production process of silicone products, and improving product quality and reliability.

[0004] Existing equipment suffers from uneven temperature distribution within the device due to the fixed position of the heating element. This uneven heating of silicone products can lead to localized overheating and result in inaccurate test results. Therefore, we propose a high-temperature resistance testing device for silicone products. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistance testing device for silicone products. Through the heating mechanism and clamping mechanism, it solves the problem that in existing equipment, the heating component is in a fixed position during testing, resulting in uneven temperature distribution within the equipment. This uneven temperature distribution leads to uneven heating of the silicone products, causing localized excessively high temperatures and resulting in deviations in the test results.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a high temperature resistance testing device for silicone products, including a testing box. The inner wall of the testing box is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a baffle. The top inner wall of the testing box is fixedly connected to a vent pipe, and the inner wall of the baffle is fixedly connected to an observation glass. The inner wall of the testing box is provided with a heating mechanism.

[0008] The heating mechanism includes a first motor, the outer wall of which is fixedly connected to the bottom of the inner wall of the testing box. The bottom output shaft of the first motor is fixedly connected to a roller via a coupling. A partition is fixedly connected to the inner wall of the testing box. The inner wall of the partition is rotatably connected to the outer wall of the roller. A disc is fixedly connected to the outer wall of the roller on the side away from the first motor. A rotating rod is rotatably connected to the inner wall of the disc. Several heating plates are fixedly connected to the inner wall of the testing box. A fixing rod is fixedly connected to the inner wall of the partition.

[0009] Furthermore, a gear is fixedly connected to the outer wall of the fixed rod on the side away from the partition, a gear is fixedly connected to the outer wall of the rotating rod, the outer wall of the gear meshes with the outer wall of the gear, and a clamping mechanism is provided on the outer wall of the rotating rod.

[0010] Furthermore, the clamping mechanism includes a placement plate, the bottom outer wall of which is fixedly connected to the outer wall of the rotating rod, a mounting bracket fixedly connected to the top outer wall of the placement plate, and a threaded rod rotatably connected to the inner wall of the mounting bracket.

[0011] Furthermore, a turntable is fixedly connected to the outer wall of the threaded rod on the side away from the mounting bracket, and a threaded block is threadedly connected to the outer wall of the threaded rod.

[0012] Furthermore, the outer wall of the threaded block is fixedly connected to several joint shafts, and the outer wall of each joint shaft is rotatably connected to a connecting rod.

[0013] Furthermore, the inner wall of the connecting rod is rotatably connected to a second joint shaft, and the outer wall of the second joint shaft is fixedly connected to a fixing plate.

[0014] Furthermore, a number of fixing blocks are fixedly connected to the top outer wall of the placement plate, and a circular groove is opened on the inner wall of the fixing block. A sliding rod is slidably connected to the inner wall of the circular groove.

[0015] Furthermore, the outer wall of the sliding rod is fixedly connected to the outer wall of the fixing plate, and a clamping plate is fixedly connected to the outer wall of the sliding rod on the side near the mounting frame.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a rotating rod and a geared disc. When the roller rotates, it carries the disc, which in turn carries the rotating rod in a circular motion. Simultaneously, the rotating rod drives the gear, which rubs against the geared disc, causing the gear to rotate. This rotation of the gear, in turn, drives the rotating rod, which in turn drives the placement plate. This design improves heating efficiency. The placement plate also moves the silicone product during the testing process, ensuring more uniform heating and preventing localized overheating that could lead to inaccurate test results.

[0018] 2. This utility model, by setting a threaded rod and a clamping plate, allows the threaded block to move when the threaded rod rotates. Simultaneously, the threaded block moves two joint shafts. When the joint shafts move, they cause the connecting rod to make an arc-shaped motion. Then, the connecting rod moves the second joint shaft, which in turn moves the fixing plate. Finally, the fixing plate moves the sliding rod. This improves the stability of the test, effectively fixes the silicone product on the equipment, and prevents the silicone product from slipping off the equipment due to thermal expansion, thus preventing interruption of the test process.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Then the roller 204... 02. The rotating disc 204 facilitates the transfer of kinetic energy between parts. A rotating rod 205 is rotatably connected to the inner wall of the disc 204. Several heating plates 206 are fixedly connected to the inner wall of the testing box 1. The heating plates 206 are model JRD-G, capable of stable operation within a temperature range of -62℃ to 235℃ or even higher, simulating the use of silicone products in various high-temperature environments. A fixing rod 207 is fixedly connected to the inner wall of the partition 203. A [missing information - likely a component or component] is fixedly connected to the outer wall of the fixing rod 207 on the side away from the partition 203. The gear 209 is fixedly connected to the outer wall of the gear 208 and the rotating rod 205. The outer wall of the gear 209 meshes with the outer wall of the gear 208. The outer wall of the rotating rod 205 is provided with a clamping mechanism 3. When the disc 204 rotates, it will drive the rotating rod 205 to move in a circular motion. Then the rotating rod 205 will drive the gear 209 to move. When the gear 209 moves, it will rub against the gear 208. Then the gear 209 will rotate due to friction. At the same time, the rotating rod 205 will rotate with the gear 209, realizing the kinetic energy transmission between the parts.

[0030] The clamping mechanism 3 includes a placement plate 301. The bottom outer wall of the placement plate 301 is fixedly connected to the outer wall of the rotating rod 205. The top outer wall of the placement plate 301 is fixedly connected to a mounting bracket 302. The inner wall of the mounting bracket 302 is rotatably connected to a threaded rod 303. The outer wall of the threaded rod 303 away from the mounting bracket 302 is fixedly connected to a turntable 304. When the turntable 304 rotates, it will cause the threaded rod 303 to rotate, realizing that when one part moves, other parts will also move. The outer wall of the threaded rod 303 is threadedly connected to a threaded block 313. The outer wall of the threaded block 313 is fixedly connected to several joint shafts 305. The outer wall of the joint shafts 305 is rotatably connected to a connecting rod 306. When the threaded rod 303 rotates, it will cause the threaded block 313 to move. When the threaded block 313 moves, it will cause the joint shafts 305 to move. Then the joint shafts 305 will cause the connecting rods 306 to make arc-shaped movements, realizing the kinetic energy transmission between the parts.

[0031] The inner wall of the connecting rod 306 is rotatably connected to a second joint shaft 307, and the outer wall of the second joint shaft 307 is fixedly connected to a fixing plate 308. When the connecting rod 306 moves, it will move the second joint shaft 307, and then the second joint shaft 307 will move the fixing plate 308, completing the kinetic energy transfer process between the parts. Several fixing blocks 309 are fixedly connected to the top outer wall of the placement plate 301. The inner wall of the fixing block 309 has a circular groove 310, and the inner wall of the circular groove 310 is slidably connected to a sliding rod 311. When the sliding rod 311 moves, it will move with the sliding rod 308. When the rod 311 slides in the circular groove 310, the sliding rod 311 will not wobble, keeping the sliding rod 311 in a straight line. The outer wall of the sliding rod 311 is fixedly connected to the outer wall of the fixing plate 308. A clamping plate 312 is fixedly connected to the outer wall of the sliding rod 311 near the mounting bracket 302. When the fixing plate 308 moves, it will move the sliding rod 311, and then the sliding rod 311 will move the clamping plate 312. When the clamping plate 312 moves, it will clamp the silicone product to prevent displacement during testing.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, first place the silicone product on the placement plate 301, positioning it between the two clamping plates 312. After placement, rotate the turntable 304, which will then rotate the threaded rod 303. As the threaded rod 303 rotates, it will move the threaded block 313, which in turn will move the two joint shafts 305. As the joint shafts 305 move, they will cause the connecting rod 306 to move in an arc. The connecting rod 306 will then move the second joint shaft 307, which will move the fixing plate 308. The fixing plate 308 will then move the sliding rod 311, which will move the clamping plate 312. The clamping plate 312 will then secure the silicone product, preventing it from falling off the placement plate 301 during testing and affecting the process. After securing the product, close the baffle 102. Then, the heating plate 206 and the first motor 201 are started simultaneously. After the heating plate 206 is started, it heats the silicone product to enable testing. Then, after the first motor 201 is started, it drives the roller 202 to rotate. When the roller 202 rotates, it drives the disc 204 to rotate. Then the disc 204 drives the rotating rod 205 to rotate. At the same time, the rotating rod 205 drives the gear 209 to move. When the gear 209 moves, it rubs against the gear disc 208. Then the gear 209 rotates due to friction. When the gear 209 rotates, it drives the rotating rod 205 to rotate. Then the rotating rod 205 drives the placement plate 301 to rotate. At the same time, the placement plate 301 moves in a circular motion with the rotating rod 205. When the placement plate 301 moves, it causes the silicone product to move and rotate, so that the silicone product is heated more evenly during high temperature resistance testing, and the test results are more accurate.
