Description

Technical Field

[0001] This solution belongs to the field of rubber elasticity testing technology, specifically involving a polymer composite rubber resilience testing device. Background Technology

[0002] The design and development of resilience testing devices for polymer composite rubber are based on the need for performance evaluation of rubber materials, especially with the advancement of industrial technology and the increasing performance requirements of rubber products in various application fields. Resilience, as an important indicator of a rubber material's ability to return to its original shape after being subjected to stress, is crucial for ensuring the quality of rubber products.

[0003] Currently, the existing instrument and method for testing the relative elasticity of rubber granules in synthetic sports field surface (announcement number CN119595474A) includes: a test platform; a granule container holding the rubber granules, located on the test platform; a lower fixture located at the bottom of the granule container for adjusting its position; a lead screw arranged vertically, perpendicular to the test platform, with a nut connected to a horizontally arranged main shaft; an upper fixture mounted on the main shaft, located above the granule container, capable of extending into the granule container to pre-compress the rubber granules under the drive of the lead screw; a pressure sensor located between the upper fixture and the main shaft, sensing the pressure of the upper fixture pre-compressing the rubber granules; and a controller configured to: cause the lead screw to drive the upper fixture into the granule container to pre-compress the rubber granules; sense the pressure through the pressure sensor; when the pre-compression time and pressure reach a set value, cause the lead screw to drive the upper fixture to retract; when the pressure sensor senses 0 pressure, obtain the rebound value of the rubber granules based on the retraction distance of the upper fixture; and compare the rebound value with a reference value to obtain the relative elasticity of the rubber granules.

[0004] However, there is also a problem: existing devices generally use laser ranging, but laser ranging often results in inaccurate data due to contamination of the measured plate. In this case, manual ranging is required, which is very troublesome to measure manually with a ruler. Utility Model Content

[0005] This solution provides a polymer composite rubber resilience testing device to solve the problem of cumbersome mechanical measurement.

[0006] This solution provides a polymer composite rubber resilience testing device, including:

[0007] Base: The base is equipped with a positioning rod;

[0008] Hydraulic cylinder: The hydraulic cylinder is fixedly connected to the base;

[0009] Hydraulic pump: The hydraulic pump is fixedly connected to the base and is connected to the hydraulic cylinder;

[0010] Upper plate: The upper plate is slidably connected to the positioning rod, and the upper plate is fixedly connected to the push rod of the hydraulic cylinder;

[0011] Lower plate: The lower plate is fixedly connected to the base, and the lower plate cooperates with the upper plate;

[0012] Controller: The controller is electrically connected to the hydraulic pump;

[0013] Height detection mechanism: used to measure the initial height and rebound height of the test piece;

[0014] The height detection mechanism includes:

[0015] Pressure plate: The pressure plate is slidably connected to the positioning rod, and the pressure plate cooperates with the lower closing plate;

[0016] Small ruler: The small ruler is fixedly connected to the pressure plate;

[0017] Reading rod: The reading rod is arranged parallel to the lower plate and is fixedly connected to the lower plate. The reading rod is used in conjunction with the small scale.

[0018] The principle of this solution is that the base provides basic support for the entire device and is equipped with a positioning rod to guide the vertical movement of components such as the upper plate and pressure plate, ensuring alignment and stability during the measurement process.

[0019] The hydraulic cylinder is fixedly connected to the base and drives its push rod to move up and down via a hydraulic pump. The upper plate is connected to the hydraulic cylinder's push rod, so its position can be precisely adjusted by controlling the hydraulic pump pressure, thereby applying a predetermined pressure to the sample. The lower plate is fixed to the base, while the upper plate can slide under the guidance of a positioning rod. When the hydraulic cylinder pushes the upper plate downward, a compressive force is applied to the sample placed between the upper and lower plates. The controller regulates the operation of the hydraulic pump, achieving precise control over the applied pressure and speed.

[0020] The pressure plate and positioning rod are slidably connected, allowing it to move up and down with the sample to ensure it remains in close contact with the sample surface throughout the measurement process. A small scale is fixed to the pressure plate and moves with it. The reading rod is parallel to and fixed to the lower plate, providing a fixed reference point. It works in conjunction with the small scale to accurately read changes in sample height.

[0021] The advantages of this design are: 1. Through precise hydraulic control and a height detection mechanism, the applied pressure and the initial and rebound height of the sample can be controlled more accurately, thus obtaining more reliable resilience data. 2. This design allows for flexible adjustment of the applied pressure and measurement range, making it suitable for polymer composite rubber samples of different types and sizes.

[0022] Furthermore, it also includes an amplification mechanism, which comprises a large gear, a small gear, a first rack, a second rack, and a fixed plate. The first rack is fixedly connected to the pressure plate, the small gear meshes with the first rack, the small gear is coaxially fixed with the large gear, the large gear is rotatably connected to the fixed plate, the fixed plate is provided with a large scale, the fixed plate is fixedly connected to the base, the second rack is slidably connected to the fixed plate, and the second rack cooperates with the large scale and meshes with the large gear.

[0023] The first rack is directly fixed to the pressure plate and moves up and down with it. This means that when the sample is deformed by pressure, the first rack moves along with the pressure plate. The pinion meshes with the first rack, so when the first rack moves up and down due to the movement of the pressure plate, it drives the pinion to rotate. The pinion and gear are mounted on the same shaft, meaning that the rotation of the pinion directly drives the gear to rotate at the same speed. The gear can rotate freely within the fixed plate, which is fixed to the base. The second rack meshes with the gear; when the gear rotates due to the drive of the pinion, it pushes the second rack to slide along the track on the fixed plate. The fixed plate has a large scale; the second rack works in conjunction with this scale to directly read the displacement transmitted by the first rack. However, due to the amplification effect of the gears, this displacement is significantly magnified, thus improving the accuracy and readability of the reading.

[0024] This mechanism uses a rack and pinion amplification mechanism to convert even minute deformations of the sample into larger displacements. This allows the system to more sensitively capture subtle changes, improving measurement resolution and accuracy.

[0025] Furthermore, two height detection mechanisms and amplification mechanisms are provided, and they are symmetrically arranged on both sides of the lower plate. By symmetrically arranging the height detection and amplification mechanisms on both sides of the lower plate, it can be ensured that the sample experiences a uniform pressure distribution during the compression-rebound process. This is to reduce measurement errors caused by uneven pressure. Simultaneously, each height detection mechanism operates independently, measuring the height from both sides of the sample separately. This method helps to capture the deformation of the sample throughout the compression-rebound cycle, providing more comprehensive data support.

[0026] Furthermore, having two independent height detection and amplification systems means that two sets of data can be obtained. These data can be compared and verified to ensure the consistency and accuracy of the measurement results. If the two sets of data differ significantly, it may indicate a problem with the equipment or the sample itself.

[0027] Furthermore, it also includes a temperature detection mechanism for detecting ambient temperature, which is fixedly connected to the lower plate. The temperature detection mechanism typically consists of one or more high-precision temperature sensors capable of monitoring real-time temperature changes in the surrounding environment. The temperature sensors are mounted on the lower plate as close as possible to the sample being measured, ensuring that the measured temperature accurately reflects the actual temperature conditions of the sample's location. This arrangement helps reduce interference from external factors (such as the influence of the laboratory air conditioning system) on the measurement results. The obtained temperature data can be used to correct or compensate for measurement errors caused by temperature changes, or as part of subsequent analysis to help researchers understand the effect of temperature on the resilience of rubber materials.

[0031] The basics are as follows: Figure 1 As shown:

[0032] This solution provides a polymer composite rubber resilience testing device, comprising the following components: a base 1 provides the basic support for the entire device and is equipped with a positioning rod 4 to guide the vertical movement of components such as the upper plate 3 and the pressure plate 7, ensuring alignment and stability during the measurement process. A hydraulic cylinder 6 is fixedly connected to the base 1 and drives its push rod to move up and down through hydraulic pump oil supply. The upper plate 3 is connected to the push rod of the hydraulic cylinder 6, so the position of the upper plate 3 can be precisely adjusted by controlling the pressure of the hydraulic pump, thereby applying a predetermined pressure to the sample.

[0033] The hydraulic pump is fixedly connected to the base 1 and communicates with the hydraulic cylinder 6, providing power to the hydraulic system. The upper plate 3 is slidably connected to the positioning rod 4 and fixedly connected to the push rod of the hydraulic cylinder 6. When the hydraulic cylinder 6 pushes the upper plate 3 downward, it applies compressive force to the sample placed between the upper and lower plates 2. The lower plate 2 is fixedly connected to the base 1 and is the same size as the upper plate 3, together clamping the sample for testing. The controller 5 is electrically connected to the hydraulic pump and is responsible for regulating the operation of the hydraulic pump, achieving precise control over the applied pressure and speed.

[0034] As attached Figure 1 , Figure 2 As shown:

[0035] The height detection mechanism is used to measure the initial height and rebound height of the test piece 15. The height detection mechanism includes a pressure plate 7, a small scale 9, and a reading rod 8. The pressure plate 7 is slidably connected to the positioning rod 4 and can move up and down with the sample, ensuring it remains in close contact with the sample surface during measurement. The pressure plate 7 is parallel to the lower plate 2, and the test piece 15 is located between the pressure plate 7 and the lower plate 2. The small scale 9 is fixed to the pressure plate 7 and provides a direct reading of the height change as the pressure plate 7 moves. The reading rod 8 is parallel to the lower plate 2 and fixed thereto, serving as a fixed reference point. It works in conjunction with the small scale 9 to accurately read the height change of the sample.

[0036] Each height detection mechanism is equipped with an amplification mechanism, including a large gear 13, a small gear 11, a first rack 10, a second rack 14, and a fixed plate 12. The first rack 10 is fixedly connected to the pressure plate 7 and moves up and down with the pressure plate 7. The small gear 11 meshes with the first rack 10, driving the small gear 11 to rotate when the first rack 10 moves. The large gear 13 is coaxially fixed with the small gear 11, and the gear ratio is set to 1:5, so that for every revolution of the small gear 11, the large gear 13 also rotates once, but the distance the second rack 14 moves is 5 times longer than the distance the first rack 10 moves. The fixed plate 12 has a large scale and is fixedly connected to the base 1, providing a stable support structure. The second rack 14 is slidably connected to the fixed plate 12 and close to the large scale, while meshing with the large gear 13. Due to the gear ratio, the displacement of the second rack 14 is 5 times that of the first rack 10, achieving a significant amplification of minute deformations and improving the accuracy and readability of the readings.

[0037] Two height detection and amplification mechanisms are provided, symmetrically arranged on the lower composite plate 2. This design ensures that the sample experiences uniform pressure distribution during stress, reducing measurement errors caused by uneven pressure. Each height detection mechanism operates independently, measuring the height from both sides of the sample, providing more comprehensive data support.

[0038] The temperature detection mechanism, fixedly connected to the lower plate 2, is used to detect ambient temperature. This mechanism consists of one or more high-precision temperature sensors that monitor real-time temperature changes in the surrounding environment, ensuring that the measured temperature accurately reflects the actual temperature conditions of the sample's location. The temperature data can be used to correct or compensate for measurement errors caused by temperature variations, or as part of subsequent analysis to help researchers understand the effect of temperature on the resilience of rubber materials.

[0039] The principle behind this design is as follows: Through a precise hydraulic control system and height detection mechanism, this device can more accurately control the applied pressure and measure the initial height and rebound height of the sample, thereby obtaining more reliable rebound data. The amplification mechanism utilizes a rack and pinion mechanism to significantly amplify minute deformations, improving the system's sensitivity and accuracy. The temperature detection mechanism provides ambient temperature monitoring, helping to eliminate the influence of temperature fluctuations on the measurement results.

[0040] The beneficial effects of this solution are as follows: 1. The symmetrically designed dual detection system and amplification mechanism effectively compensate for measurement deviations in a single direction, improving measurement resolution and accuracy. 2. Two independent sets of data enhance the reliability of a single measurement and provide more reference information for long-term monitoring. 3. Sufficient information for analysis can be obtained from a single measurement, reducing the number of repeated experiments. 4. It can adapt to a wider range of application scenarios, whether in laboratory environments or real-world applications, expanding its applicability.
