After the machine is operating normally (it can be carried out at the same time as the test in 6.3.2), the total number of covers and the number of damaged covers input into the tilting machine within 8 hours are counted (covers damaged due to poor quality are not included), and the cover damage rate is calculated according to formula (8), which should comply with the provisions of 5.2.6.
R=×100%
Where:
cover rate, device:
loss number, unit is piece,
f一---Total number of caps, in pieces.
6.3.9 Bottle cap opening torque test
When the bottle capping machine is operating normally, take several times the number of sample bottles that have been screwed on each time, and the sampling interval is 5 minutes, and the sample is withdrawn 10 times: Use a torque meter with a dynamic accuracy of 1% to test the bottle cap opening torque, which should comply with the provisions of 5.2.8. 6.3. 10
Sealing test
When the bottle capping machine is operating normally, take several times the number of sample bottles that have been screwed on each time, and the sampling interval is 5 minutes, and the sample is withdrawn 10 times in total. Carry out sealing test according to the requirements of GB/T17876, which should comply with the provisions of 5.2.9. 6. 3. 11 Carbon dioxide gas capacity inspection
According to GB/T10792-2C08 Measure the capacity of carbon dioxide in accordance with the provisions of 6.2.1: meet the requirements of 5.2.10, 6.3.12 Finished product qualification rate test
6.3.12.1 Finished product appearance quality inspection basket
The test is carried out on the user's site, the rotary machine runs continuously at the rated speed for 8 hours (can be carried out during the test of 6.3.2), 1000 sample bottles, which should meet the requirements of 5.2.7, and the number of unqualified products is counted α1 6.3.12.2 Filling liquid level difference test
Take For the sample bottles with qualified appearance quality, the filling liquid level height shall be measured according to the test method given in 6.3.5.2, which shall comply with the provisions of 5.2.3b). The number of unqualified products in the filling liquid level difference α2 shall be counted and the finished product qualification rate shall be calculated according to formula (9)
K = finished product qualification rate, %:
aa) × 100%
Number of unqualified products in finished product appearance quality, in bottles; 21
α2 Number of unqualified products in the filling liquid level difference, in bottles. The calculation result shall comply with the provisions of 5.2.11. 6.3.13 Noise test
During the reverse working process, the noise of the filling and capping machine shall be measured according to the method specified in JB/T7232, and its noise value shall comply with the provisions of 5.2.12.
