Description

Technical Field

[0001] This utility model relates to the field of elastomer rebound testing technology, and more specifically to a thermoplastic elastomer rebound tester. Background Technology

[0002] Thermoplastic elastomers, also known as thermoplastic rubbers, are materials that combine the properties of rubber and thermoplastic plastics. They exhibit rubber-like characteristics at room temperature but can be plasticized and molded at high temperatures. Their products possess the excellent properties of traditional cross-linked vulcanized rubber, such as high elasticity, aging resistance, and oil resistance, while also having the advantages of ordinary plastics, such as convenient processing and a wide range of processing methods. During processing, it is necessary to test their resilience to ensure the resilience performance of thermoplastic elastomers.

[0003] Existing thermoplastic elastomer rebound testers typically place the elastomer on the test platform and drop a marble into a ball cylinder. After contacting the elastomer, the marble rebounds into the cylinder, and the rebound height of the marble is observed to determine the resilience of the elastomer. However, since the marble is dropped visually from the middle of the cylinder, it is prone to significant errors. During its fall, the marble is likely to collide with the cylinder wall, hindering its free fall and reducing the impact force on the elastomer. This significantly affects the rebound test, leading to large data deviations and hindering accurate testing.

[0004] Based on the above background, a thermoplastic elastomer rebound tester is proposed to solve the problem. Utility Model Content

[0005] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a thermoplastic elastomer rebound tester.

[0007] To achieve the above objectives, the technical solution of this utility model is: a thermoplastic elastomer rebound tester, comprising: a support arm, a mounting frame, a ball bearing assembly, indicator lights, and a test object placement platform. The mounting frame is mounted on the support arm, the ball bearing assembly is mounted on the support arm, and the ball bearing assembly is equipped with several indicator lights. The test object placement platform is connected to the lower side of the support arm and located below the ball bearing assembly. The ball bearing assembly includes a cylinder, a rotating shaft, a sealing plate, a spring, a pull rod, and inductive sensors. Rotating shafts are inserted into both sides of the cylinder's interior. The sealing plate is rotatably connected to the rotating shafts. One side of the spring is connected to the side of the cylinder, and the other side is connected to the sealing plate. The pull rod passes through the cylinder and connects to the sealing plate. The lower ends of the two sealing plates are abutted and located in the middle of the cylinder. Several inductive sensors electrically connected to the indicator lights are installed on the inner wall of the cylinder.

[0008] Preferably, the cylinder is mounted on the mounting frame and its lower side is located above the test object placement platform.

[0009] Preferably, the end of the pull rod located on the outside of the cylinder is connected to a pull head.

[0010] Preferably, the outer side of the cylinder is engraved with scale markings corresponding to the position of the indicator light.

[0011] Preferably, the test object placement stage is equipped with an object holder.

[0012] Preferably, a slide rail is installed on the inner wall of the object holder, and bolts are threaded on both sides of the object holder. Clamps connected to the slide rail are provided on both sides inside the object holder, and one side of the bolt is screwed into the object holder and abuts against the clamp.

[0013] As a preferred option, the bottom surface of the test object placement platform is equipped with several anti-slip posts.

[0014] As a preferred option, the anti-slip posts are made of rubber.

[0015] The beneficial effects of this utility model are as follows: When the marble is thrown into the cylinder, it is held in place by two closed plates at the center of the cylinder before being lowered. This helps to keep the marble falling towards the center of the cylinder, preventing friction and collision with the cylinder wall, and allowing it to fall freely onto the elastic element. As a result, the rebound test process is not affected by other factors, thereby improving the accuracy of the rebound test of the elastic element and making the test data more precise, which is more conducive to the test.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-3 This utility model provides a thermoplastic elastomer rebound tester, including: a support arm 1, a mounting frame 2, a ball bearing assembly 3, indicator lights 4, and a test object placement platform 5. The mounting frame 2 is disposed on the support arm 1, the ball bearing assembly 3 is mounted on the support arm 1, and a plurality of indicator lights 4 are installed on the ball bearing assembly 3. The test object placement platform 5 is connected to the lower side of the support arm 1 and is located below the ball bearing assembly 3. The ball bearing assembly 3 includes a cylinder 31, a rotating shaft 32, a sealing plate 33, a spring 34, a pull rod 35, and a sensor 36. The rotating shaft 32 is fitted into both sides of the inside of the cylinder 31. The sealing plate 33 is rotatably connected to the rotating shaft 32. One side of the spring 34 is connected to the side of the cylinder 31, and the other side is connected to the sealing plate 33. The pull rod 35 passes through the cylinder 31 and is connected to the sealing plate 33. The lower ends of the two sealing plates 33 are abutted and located in the middle of the cylinder 31. A plurality of sensor 36 electrically connected to the indicator lights 4 are installed on the inner wall of the cylinder 31.

[0023] When using the device, place the elastic element on the test platform 5, then drop the marble into the cylinder 31. The marble stays between the two closed plates 33, that is, at the center of the cylinder 31. Then, pull the lever 35 outwards at the same time. The closed plates 33 rotate and open under the action of the rotating shaft 32, and the marble falls down. After contacting the elastic element, it rebounds into the cylinder 31. When the sensing sensor 36 senses that the marble has rebounded to the corresponding height, it controls the indicator light 4 to light up, so that the personnel can know the rebound height, thus completing the rebound test of the elastic element.

[0024] According to some embodiments of this application, optionally, the cylinder 31 is disposed on the mounting frame 2 and its lower side is located above the test object placement platform 5.

[0025] According to some embodiments of this application, optionally, a pull head 37 is connected to one end of the pull rod 35 located outside the cylinder 31. This facilitates pulling the pull rod 35 and makes operation easier.

[0026] According to some embodiments of this application, optionally, a scale number 6 is engraved on the outer side of the cylinder 31 at the position corresponding to the indicator light 4. This facilitates the determination of the specific rebound height data.

[0027] According to some embodiments of this application, optionally, a test object placement platform 5 is equipped with an object holder 7, a slide rail 8 is installed on the inner side wall of the object holder 7, and bolts 9 are threaded to both sides of the object holder 7. Clamping plates 10 connected to the slide rail 8 are provided on both sides inside the object holder 7. One side of the bolt 9 is screwed into the object holder 7 and abuts against the clamping plate 10. To prevent the elastic element from moving due to the impact force when the ball falls on it, causing the ball to rebound in a different direction and increasing the frequency of rebound test errors, this application rotates the bolt 9, which screws into the object holder 7 and pushes the clamping plate 10. The clamping plate 10 moves towards the elastic element under the action of the slide rail 8 until it clamps the elastic element, thus fixing and clamping it, effectively preventing it from moving due to the impact of the ball, thereby making the rebound test more accurate and reducing the error frequency.

[0028] According to some embodiments of this application, optionally, a plurality of anti-slip posts 11 are installed on the bottom surface of the test object placement platform 5. These posts serve to prevent slippage on the testing instrument.

[0029] According to some embodiments of this application, optionally, the anti-slip post 11 is made of rubber, which provides a good anti-slip effect.
