海綿落球回彈試驗(yàn)儀  使用說明書

1.將落球回彈試驗(yàn)儀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將放置平面調(diào)成水平，然后查看一下落球回彈上面板是否水平，如果不水平，通過轉(zhuǎn)動(dòng)底座螺絲，調(diào)成水平（出廠時(shí)已調(diào)，如果運(yùn)輸過程中，有改變需要再調(diào)一下）。

2.根據(jù)要做試驗(yàn)的高度，調(diào)整試驗(yàn)下落高度，按上或取下高度調(diào)節(jié)塊。

3.將落球回彈試驗(yàn)儀主機(jī)上的傳感器數(shù)據(jù)線接到控制箱上的“數(shù)據(jù)線”接口，將5V電源接到控制箱上的“電源”接口，然后打開“電源開關(guān)”，給設(shè)備供電。

4.將試樣切成100mm*100mm*50mm，放到試樣平臺(tái)上，調(diào)節(jié)平臺(tái)高度，使試樣與上面板夾緊。

5.這時(shí)儀器上會(huì)顯示“歡迎使用落球回彈測(cè)試系統(tǒng)”，點(diǎn)擊“測(cè)試”會(huì)進(jìn)入選擇試驗(yàn)高度界面,繼續(xù)按“測(cè)試”鍵，會(huì)在500mm與460mm之間切換，當(dāng)箭頭指向相應(yīng)高度時(shí)，點(diǎn)擊“確定”，進(jìn)入試驗(yàn)界面。

6.此時(shí)界面顯示，“試驗(yàn)中”，通過鋼球釋放裝置將鋼球釋放，此時(shí)顯示試驗(yàn)結(jié)束，如果此次試驗(yàn)沒有碰壁，點(diǎn)擊“確定”，保存試驗(yàn)結(jié)果，試驗(yàn)數(shù)據(jù)有效，否則點(diǎn)擊“取消”，試驗(yàn)無(wú)效。

7.通過鋼球釋放裝置將鋼球取出，點(diǎn)擊“測(cè)試”，屏幕顯示“試驗(yàn)中”，繼續(xù)試驗(yàn)，如此試驗(yàn)9次有效試驗(yàn)，點(diǎn)擊“打印”打印試驗(yàn)報(bào)告。

8.在任何時(shí)候都可以通過“返回”按鈕，使以前所有試驗(yàn)無(wú)效，從新開始。

9．試驗(yàn)報(bào)告包括試驗(yàn)高度，試驗(yàn)次數(shù)，平均回彈高度，平均回彈率四部分信息。

10.試驗(yàn)結(jié)束后關(guān)閉“電源開關(guān)”，結(jié)束試驗(yàn)。

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.
