海绵落球回弹试验仪 使用说明书
1.将落球回弹试验仪放置在水平桌面或地面上，如果放置平面不水平可用水平尺先将放置平面调成水平，然后查看一下落球回弹上面板是否水平，如果不水平，通过转动底座螺丝，调成水平（出厂时已调，如果运输过程中，有改变需要再调一下）。
2.根据要做试验的高度，调整试验下落高度，按上或取下高度调节块。
3.将落球回弹试验仪主机上的传感器数据线接到控制箱上的“数据线”接口，将5V电源接到控制箱上的“电源”接口，然后打开“电源开关”，给设备供电。
4.将试样切成100mm*100mm*50mm，放到试样平台上，调节平台高度，使试样与上面板夹紧。
5.这时仪器上会显示“欢迎使用落球回弹测试系统”，点击“测试”会进入选择试验高度界面,继续按“测试”键，会在500mm与460mm之间切换，当箭头指向相应高度时，点击“确定”，进入试验界面。
6.此时界面显示，“试验中”，通过钢球释放装置将钢球释放，此时显示试验结束，如果此次试验没有碰壁，点击“确定”，保存试验结果，试验数据有效，否则点击“取消”，试验无效。
7.通过钢球释放装置将钢球取出，点击“测试”，屏幕显示“试验中”，继续试验，如此试验9次有效试验，点击“打印”打印试验报告。
8.在任何时候都可以通过“返回”按钮，使以前所有试验无效，从新开始。
9．试验报告包括试验高度，试验次数，平均回弹高度，平均回弹率四部分信息。
10.试验结束后关闭“电源开关”，结束试验。

1. Place the ball rebound tester on a horizontal tabletop or ground. If the placement plane is not horizontal, use a level ruler to adjust the placement plane to horizontal first, and then check if the top panel of the ball rebound is horizontal. If it is not horizontal, adjust it to horizontal by turning the base screw (it has been adjusted when leaving the factory, but if there are changes during transportation, it needs to be adjusted again).
2. Adjust the height of the test drop according to the height to be tested, and press or remove the height adjustment block.
3. Connect the sensor data cable on the host of the ball drop rebound tester to the "data cable" interface on the control box, connect the 5V power supply to the "power" interface on the control box, and then turn on the "power switch" to supply power to the equipment.
4. Cut the sample into 100mm * 100mm * 50mm, place it on the sample platform, adjust the platform height, and clamp the sample tightly with the upper panel.
5. At this point, the instrument will display "Welcome to use the ball drop rebound testing system". Clicking "Test" will enter the interface for selecting the test height. Continuing to press the "Test" button will switch between 500mm and 460mm. When the arrow points to the corresponding height, click "OK" to enter the test interface.
At this point, the interface displays "Under Test". The steel ball is released through the steel ball release device, indicating the end of the test. If the test did not hit the wall, click "OK" to save the test results, and the test data will be valid. Otherwise, click "Cancel", and the test will be invalid.
7. Use the steel ball release device to remove the steel ball, click "Test", and the screen will display "Under Test". Continue the test for 9 valid tests, and click "Print" to print the test report.
At any time, you can use the 'back' button to invalidate all previous experiments and start anew.
9. The test report includes four parts of information: test height, test frequency, average rebound height, and average rebound rate.
10. After the experiment is completed, turn off the "power switch" to end the experiment.
Scope and Function of Application:
It is suitable for measuring the falling ball resilience of soft polyurethane foam. The springback of falling ball is to calculate the percentage of the ratio of the maximum height of the springback of the steel ball to the falling height of the steel ball, namely the springback rate, by which the springback performance of the foam plastic is expressed. Meet the testing methods of Method A and Method B in the 08 standard. It mainly tests the resilience of plastic foam materials and sponge materials. The measurement accuracy of the rebound of the falling ball is high, controlled by a microprocessor, displayed in Chinese, and the test data can be printed.
