Problems solved by technology

In the prior art, such as Chinese patents CN201016823Y and CN2932347Y both provide a bottle cap unscrewing torque tester, but the problem is that they do not take into account the detection of the twist angle when the bottle cap is unscrewed, and do not take into account Influence of Cap Axial Displacement on Accuracy of Torque Test Results when Cap is Twist
However, the existing commercially available bottle cap twisting torque test equipment can measure the torque value when the bottle cap is twisted, but the general structure is simple, the precision and the degree of automation are low. Monitoring, as well as batch quality inspection of scientific research institutions or testing institutions, etc., all bring a large workload and low efficiency
In addition, it is very important that the twist-off angle of the bottle cap is also one of the main evaluation criteria for the twist-off performance of this type of bottle cap, but none of the existing equipment has this function

Embodiment 1

[0054] This embodiment is used to illustrate the test process and results of the twist-off performance of a disposable packaging plastic bottle cap package using the bottle cap twist-off performance test device provided by the present invention.

[0055] The disposable packaging plastic bottle cap package in this embodiment is a commercially available 500ml carbonated beverage bottle cap package, the bottle cap is a polypropylene plastic bottle cap, and the height of the bottle body is 24.5cm.

[0056] When the twist-off performance of this bottle cap package was tested, the distance between the twist-off part 10 and the fixed part 13 of the device of the present invention was adjusted to 24.5 cm, and the measured bottle cap package was placed between the twist-off part 10 and the fixed part 13. Between, and the cap body part of the bottle cap is clamped by the first clamping part 11 on the unscrewed part 10, and the bottom part of the bottle is clamped by the second clamping p...

Embodiment 2

[0059] This embodiment is used to illustrate the test process and results of the twist-off performance of a disposable packaging plastic bottle cap package using the bottle cap twist-off performance test device provided by the present invention.

[0060] The disposable packaging plastic bottle cap package in this embodiment is a commercially available bottle cap package for 330ml drinking water, the bottle cap is a polypropylene plastic bottle cap, and the height of the bottle body is 15cm.

[0061] The twist-off performance test of the bottle cap package adopts the method of Example 1, the difference is that the distance between the twist-off part 10 and the fixed part 13 is adjusted to 15 cm, and the test twist-off rotation rate is set to 90 degrees / s.

[0062] The test of this bottle cap packaging unscrew performance, adopts the method that respectively gets 5 bottle cap samples and carries out parallel test, to verify the test stability performance of the device of the pres...

Embodiment 3

[0066] This embodiment is used to illustrate the test process and results of the twist-off performance of a disposable packaging metal bottle cap package using the bottle cap twist-off performance test device provided by the present invention.

[0067] The disposable packaging metal bottle cap package in this embodiment is a bottle cap package of a commercially available 400ml fruit juice drink, the bottle cap is a metal aluminum bottle cap, and the height of the bottle body is 17cm.

[0068] The twist-off performance test of the bottle cap package adopts the method of Example 1, the difference is that the distance between the twist-off part 10 and the fixed part 13 is adjusted to 17 cm, and the test twist-off rotation rate is set to 5 degrees / s.

[0069] Finally, through the test of the device of the present invention, it is obtained that the twist-off angle of the disposable packaging metal cap package is 50 degrees, and the twist-off torque is 2.0 N·M.
