[0050] The silicone tensile tester of this utility model is described in detail below with reference to the accompanying drawings.

[0051] Reference Figures 1 to 3 As shown, the silicone tensile tester provided in this embodiment of the present invention includes: a bracket 10, two clamping seats 20, two sets of clamping test components 30, and a driving mechanism 40. The two clamping seats 20 are located at the lower end of the bracket 10 and are respectively located on both sides of the bracket 10. The two sets of clamping test components 30 are respectively located above the two clamping seats 20 and are movable along the vertical direction of the bracket 10. The two sets of clamping test components 30 move in opposite directions so that when the two sets of clamping test components 30 are driven, they move alternately up and down in the vertical direction. The driving mechanism 40 is located at the bottom of the bracket 10 and is connected to the two sets of clamping test components 30 in a transmission connection to drive the two sets of clamping test components 30 to move alternately up and down.

[0052] The two clamping seats 20 can simultaneously clamp and fix silicone. When one set of clamping test components 30 lifts the silicone for testing, the other set lowers synchronously to clamp the silicone. When one set of tests is completed, the silicone on the corresponding clamping seat 20 can be removed and replaced. Thus, when one set lowers to clamp the silicone, the other set can pull the clamped silicone up and test it. This alternating testing can improve testing efficiency. Furthermore, different silicones can be clamped on the two clamping seats 20 for tensile testing.

[0053] Specifically, the support 10 includes a base 11 and a hollow seat 12. The hollow seat 12 is disposed on the base 11 and extends vertically upward. Two sets of clamping test components 30 are movably disposed on the hollow seat 12. Each set of clamping test components 30 includes: a sliding plate 31, a tension sensor 32, and a first gripper 33. The sliding plate 31 is movably disposed on the hollow seat 12 in the vertical direction. The tension sensor 32 is disposed at the bottom of the sliding plate 31. The first gripper 33 is disposed at the bottom of the tension sensor 32 and is located above the clamping seat 20.

[0054] In this embodiment, when the sliding plate 31 rises or falls, since the tension sensor 32 and the first gripper 33 are both located at the bottom of the sliding plate 31, the tension sensor 32 and the first gripper 33 can rise or fall with the sliding plate 31. The first gripper 33 can clamp the silicone from the clamping seat 20, and when the sliding plate 31 rises, it can pull the silicone so that the tension of the silicone can be transmitted to the tension sensor 32 to complete the detection. Optionally, the first gripper 33 can be a cylinder gripper, such as the cylinder gripper of SMC's MHZ2 series. The tension sensor 32 can be connected to a computer to transmit the detected data to the computer for recording and analysis. It is understood that the tension sensor 32 can be existing, and its specific working principle is well known to those skilled in the art, and will not be described in detail here.

[0055] Reference Figure 4As shown, in a preferred embodiment, the first gripper 33 includes: a receiving seat 331, a cylinder 332, a moving block 333, two pivot members 334, and two gripping claws 335. The receiving seat 331 is fixed to the bottom of the tension sensor 32, so that the receiving seat 331 can be driven by the tension sensor 32 and the sliding plate 31 to move upward or downward. The cylinder 332 is disposed in the receiving seat 331. The moving block 333 is movably disposed in the receiving seat 331 and connected to the piston rod of the cylinder 332, so that the cylinder 332 can drive the moving block 333 to move upward or downward. One end of each of the two pivot members 334 is pivotally connected to the moving block 333. When the moving block 333 moves downward, the two pivot members 334 are pushed open by the moving block 333. Two gripping claws 335 are pivotally disposed within the receiving seat 331, and the first ends of the two gripping claws 335 are pivotally connected to the other ends of the two pivot members 334 respectively. When the two pivot members 334 open, the first ends of the two gripping claws 335 are also pushed open by the two pivot members 334. When the second ends of the two gripping claws 335 extend outside the receiving seat 331, the second ends of the gripping claws 335 will pivot and move closer together. When the moving block 333 moves upward, the two pivot members 334 are pushed and closed by the moving block 333, so that the first ends of the two gripping claws 335 are pushed and closed by the two pivot members 334. When the second ends of the two gripping claws 335 extend outside the receiving seat 331, the second ends of the gripping claws 335 will pivot and open together.

[0056] Furthermore, each clamping claw 335 is provided with an air blowing hole 3351, which extends from the clamping surface of the clamping claw 335 to the side of the clamping claw 335. A connector can be provided on the side of the clamping claw 335 to connect an air pipe. The connector on the side of the clamping claw 335 should avoid the receiving seat 331. Then, it is connected to an air compressor through the air pipe so that a high-pressure airflow is blown out of the air blowing hole 3351 through the air compressor. When the high-pressure airflow enters the air blowing hole 3351, the high-pressure airflow is blown out from the clamping surface through the air blowing hole 3351. Since the clamping surface is used to clamp the silicone, after the tensile test is completed, the silicone can be blown away by the high-pressure airflow to make it detach from the clamping claw 335. This can prevent the silicone from sticking to the clamping claw 335 after being clamped, and can reduce the operation of the test process.

[0057] Furthermore, the hollow base 12 is provided with a slide rail 50, and the sliding plate 31 is slidably connected to the slide rail 50 via a slider 51. The slide rail 50 extends vertically within the hollow base 12, and the slider 51 connects the sliding plate 31 to the slide rail 50, making the sliding plate 31 more stable and reliable when moving up and down. Optionally, the inner side of the hollow base 12 has a sliding opening 121, and the sliding plate 31 passes through the sliding opening 121 and can slide within it. The width of the sliding opening 121 is greater than the width of the sliding plate 31, allowing the sliding plate 31 to move stably within the sliding opening 121.

[0058] Reference Figure 2 and Figure 3 As shown, the drive mechanism 40 includes: a motor 41, a first bevel gear 42, two drive shaft assemblies 43, and two lead screws 44. The motor 41 is located inside the base 11, and the first bevel gear 42 is located on the motor shaft of the motor 41. When the motor 41 is working, it can drive the first bevel gear 42 to rotate. The two drive shaft assemblies 43 are on the same axis and are connected to the first bevel gear 42 for transmission, so that when the first bevel gear 42 rotates, the two drive shaft assemblies 43 can rotate synchronously with the first bevel gear 42, and the rotation directions of the two drive shaft assemblies 43 are opposite. When the two drive shaft assemblies 43 rotate, since the two lead screws 44 are rotatably located inside the hollow seat 12 and are respectively connected to the two drive shaft assemblies 43, the rotation of the two drive shaft assemblies 43 is... Two lead screws 44 can rotate with two transmission shaft assemblies 43 respectively. Since the rotation directions of the two transmission shaft assemblies 43 are opposite, the rotation directions of the two lead screws 44 are also opposite. Through the threaded transmission connection between the sliding plate 31 and the lead screw 44, when the two lead screws 44 rotate with the two transmission shaft assemblies 43 respectively, when one sliding plate 31 is driven to rise with the lead screw 44, the other sliding plate 31 is driven to fall with the lead screw 44. Thus, the two sliding plates 31 can drive their respective tension sensors 32 and first grippers 33 to perform clamping and tensile testing operations on the silicone, so that the two sets of clamping and testing components 30 can move up and down alternately and complete the clamping and testing operations alternately, improving the testing efficiency.

[0059] It is understood that each drive shaft assembly 43 includes: a shaft portion 431, a second bevel gear 432, and a worm gear 433. The shaft portion 431 is rotatably disposed within the base 11. The second bevel gear 432 is disposed at one end of the shaft portion 431 and meshes with the first bevel gear 42, so that when the first bevel gear 42 rotates, it can drive the second bevel gear 432 and the shaft portion 431 to rotate synchronously. The worm gear 433 is disposed at the other end of the shaft portion 431 and is connected to the lead screw 44. Each lead screw 44 includes: a threaded rod portion 441 and a worm wheel 442. Part 441 is rotatably disposed within the hollow seat 12 and is threadedly connected to the sliding plate 31; worm gear 442 is disposed at one end of the threaded rod part 441 and is connected to the worm 433. Through the meshing transmission of worm gear 442 and worm 433, when the worm 433 rotates with the shaft part 431, the worm gear 442 can rotate with the worm 433 and drive the threaded rod part 441 to rotate, so that the threaded rod part 441 can realize threaded transmission with the sliding plate 31, thereby driving the sliding plate 31 to rise or fall on the slide rail 50.

[0060] Specifically, the clamping base 20 includes a telescopic rod 21 and a second clamping jaw 22. The telescopic rod 21 is fixed to the base 11, and the second clamping jaw 22 is fixed to the telescopic rod 21. The second clamping jaw 22 can be the same as the first clamping jaw 33, or it can be a cylinder clamping jaw. When the silicone to be tested is placed on the second clamping jaw 22, it can be clamped and fixed. When the first clamping jaw 33 descends to clamp the silicone, it can be raised after clamping, so that the first clamping jaw 33 is away from the second clamping jaw 22, allowing the silicone to be stretched for testing. The tensile force is then measured by the tensile force sensor 32, simplifying the testing operation. Preferably, the telescopic rod 21 and the base 11 can be telescopically connected, making the height of the telescopic rod 21 and the second clamping jaw 22 adjustable. When testing the tensile force of different silicones, the height can be adjusted... The height of the telescopic rod 21 on the base 11 allows for adjustment of the distance between the first gripper 33 and the second gripper 22 to different levels. The telescopic rod 21 can be secured to the base 11 using fasteners 60. For example, adjusting the telescopic rod 21 downwards increases the distance between the first gripper 33 and the second gripper 22, while adjusting it upwards decreases the distance. This allows the first gripper 33 to pull the silicone through the distance between the first gripper 33 and the second gripper 22, resulting in a simpler overall structure.

[0061] The silicone tensile tester provided by this utility model can clamp and fix silicone through two clamping seats 20, and drive mechanism 40 drives two sets of clamping test components 30 to move up and down alternately, so that the two sets of clamping test components 30 can clamp the silicone on the corresponding clamping seats 20 when moving up and down alternately, thereby completing the stretching of silicone to complete the tensile test, thereby reducing the time of silicone testing process and improving testing efficiency.
