Claim 5:
6. A test method for a lip sticking force of tipping paper for cigarettes, using the test system according to claim 1 to perform a test, and comprising the following steps:
attaching a to-be-tested tipping paper sample to a lower end of the sample loading module, then connecting the sample loading module to the rigid rope, and clearing a load force on the rigid rope at this time;
placing the artificial lip directly below the sample loading module;
controlling the sample loading module to descend by the friction meter testing platform, wherein the artificial lip is in contact with the to-be-tested tipping paper sample with a contact area of 1.5 cm*1.5 cm; and after contact, controlling the rigid rope to pull the sample loading module away from the artificial lip until a moment of separation, and controlling the movement of the rigid rope by the friction meter testing platform and recording a maximum force on the rigid rope during the test, wherein the maximum force is recorded as the lip sticking force with a value of F, and
classifying a lip sticking force grade and lip sticking performance according to the value of the lip sticking force by a method comprising:
when 0 N≤F<0.2 N, determining that a result of the lip sticking force grade is grade 0, and the lip sticking does not exist;
when 0.2 N≤F<0.3 N, determining that the result of the lip sticking force grade is grade 1, and the lip sticking is mild;
when 0.3 N≤F<0.5 N, determining that the result of the lip sticking force grade is grade 2, and the lip sticking is moderate;
when 0.5 N≤F<0.6 N, determining that the result of the lip sticking force grade is grade 3, and the lip sticking is heavy; and
when F≥0.6 N, determining that the result of the lip sticking force grade is grade 4, and the lip sticking is severe.
