Description

Technical Field

[0001] This utility model relates to the field of performance testing technology for vibration damping pads, specifically a novel performance testing device for vibration damping pads. Background Technology

[0002] Vibration damping pads are mainly used in residential buildings, hotels, and other entertainment venues and places requiring sound insulation and vibration reduction. They are a high-performance floating floor material with excellent cost-effectiveness. To ensure that the vibration damping rubber can effectively isolate and absorb vibrations in various applications, it is necessary to conduct elasticity tests. When conducting large-scale elasticity tests on vibration damping rubber, a fixed thickness of vibration damping rubber is selected. The rubber is then compressed by extrusion, and the compression force is removed. The rubber is allowed to recover its elasticity, and the thickness of the recovered rubber is measured and compared with the thickness before compression to obtain data on the elasticity characteristics of the vibration damping rubber, thus completing the test of the elasticity characteristics of the vibration damping rubber.

[0003] As disclosed in CN118641353B, a testing device and method for vibration-damping rubber includes: an unwinding roller, a winding roller, a separator, and a cutting section. The unwinding roller and the winding roller are rotatably connected to the left and right sides of an upper pressure plate, respectively. The separator is wound around the unwinding roller, and one end of the separator is connected to the winding roller. The unwinding roller can rotate and unwind the separator, and the winding roller can rotate and wind the separator. The separator can separate the compressed vibration-damping rubber from the upper pressure plate. The cutting section is mounted on the upper pressure plate and can move down to cut off the separator that is attached to the vibration-damping rubber. The testing device and method for vibration-damping rubber of the present invention separates the vibration-damping rubber block from the upper pressure plate through the separator and cuts off the separator that is attached to the vibration-damping rubber block by the cutting section, so as to prevent the compressed vibration-damping rubber block from adhering to the bottom of the upper pressure plate.

[0004] The aforementioned patent proposes that the vibration damping rubber block and the upper pressure plate can be separated by a partition, and the partition attached to the vibration damping rubber block can be cut off by a cutting part. However, during the use of the vibration damping pad performance testing equipment, the vibration damping pad is transported by a ring steel belt. When conducting the test, the aging effect of the vibration damping pad material itself is not considered, which does not conform to the actual use condition and is prone to misjudgment of the material performance. Summary of the Invention

[0005] The purpose of this invention is to provide a novel performance testing device for vibration damping pads, in order to solve the problem mentioned in the background art that the aging effect of the vibration damping pad material itself is not considered during testing, which does not conform to the actual use condition and is prone to misjudgment of material performance.

The electric push rod can control the opening and closing plate up and down, so that the two ends of the test frame are opened, allowing the vibration damping pad to be conveyed out.

[0008] Preferably, the inner wall of the test frame is equipped with a guide block, which has a triangular shape. Both ends of the test frame have an outlet, and the two outlets are of different sizes. The inclined surface of the guide block is used to guide the vibration damping pad.

[0009] Preferably, the conveying mechanism includes a support frame and a motor mounted on the outer wall of the support frame.

An inclined block is installed inside the support frame, and the cross-section of the inclined block is triangular. The brush is in critical contact with the conveyor belt, which can clean the surface of the conveyor belt.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The system utilizes a processing table, conveying mechanism, elasticity testing structure, and control panel. The conveying mechanism transports the vibration damping pads, and the aging test structure subjectes them to ultraviolet radiation to accelerate their aging. The pads are then transported to the bottom of the elasticity testing structure for pressure testing, which conforms to the actual usage conditions of the vibration damping pads and effectively improves the reliability of the test.

[0013] 2. The guide blocks and guide plates can guide the vibration damping pads to slide smoothly on the conveyor belt until they move under the lower pressure plate, where elasticity tests can be performed.

By setting up control panel 4, the electrical components of the device can be controlled.

[0019] The elasticity test structure 3 includes a test frame 31 and a cylinder component 32 mounted on the bottom wall of the test frame 31. A lower pressure plate 33 is mounted on the lower end of the cylinder component 32. An anti-stick layer 34 is uniformly coated on the surface of the lower pressure plate 33. An aging test structure 14 is also mounted on the upper end of the processing table 1. The aging test structure 14 is located on one side of the test frame 31. The aging test structure 14 is used to irradiate the vibration damping pad with ultraviolet light to accelerate the aging of the vibration damping pad. In conjunction with the elasticity test structure 3, the elasticity test can be performed on it, which conforms to the actual use state of the vibration damping pad and effectively improves the reliability of the test.

[0020] The aging test structure 14 includes a test frame 141 and an ultraviolet lamp 142 installed on the top wall inside the test frame 141. The ultraviolet lamp 142 is a UV-A (320-400 nm) lamp. The ultraviolet lamp 142 irradiates the surface of the vibration damping pad with ultraviolet light. A sliding groove 147 is opened inside the test frame 141. A sliding opening and closing plate 143 is slidably connected in the sliding groove 147. An observation window is embedded on the surface of the opening and closing plate 143. A mounting bracket 144 is fixedly installed at the upper end of the test frame 141. An electric push rod 145 is installed at the upper end of the mounting bracket 144. The telescopic end of the electric push rod 145 is connected to the top wall of the opening and closing plate 143. The electric push rod 145 can control the opening and closing plate 143 up and down, so that the outlets at both ends of the test frame 141 are opened, allowing the vibration damping pad to be conveyed out.

[0021] The conveying mechanism 2 includes a bracket 21 and a motor 22 mounted on the outer wall of the bracket 21. The output end of the motor 22 is connected to a rotating roller 23. A conveyor belt 24 is wound around the outside of the rotating roller 23. When the motor 22 is started, the rotating roller 23 can be driven to rotate. In conjunction with the conveyor belt 24, the vibration damping pad can be conveyed to the bottom of the elastic test structure 3.

[0022] The processing table 1 has an opening groove 13 inside for the conveyor belt 24 to pass through, so that the conveyor belt 24 can be placed on the processing table 1.

[0023] In this embodiment: the vibration damping pad is transported by the conveying mechanism 2 into the test frame 141. Then, the electric push rod 145 is activated to push the opening and closing plate 143 downward, closing the outlet of the test frame 141. At the same time, the ultraviolet lamp 142 is turned on to irradiate the vibration damping pad, allowing it to be exposed to ultraviolet radiation and accelerating its aging process.

After the aging test, the guide block 146 can change the size of the outlet on one side of the test frame 141, thereby reducing the offset of the vibration damping pad position and allowing it to move to the bottom of the pressure plate 33 for pressure testing.

[0029] In this embodiment: During the process, the brush 112 can clean the surface of the conveyor belt 24, thereby effectively removing the debris adhering to the conveyor belt 24 and making it cleaner.
