Paper bag lifting fatigue tester is a test equipment used to evaluate the strength and durability of paper bags during repeated lifting and lifting processes. The tester evaluates the quality and reliability of paper bags by simulating the repetitive stresses experienced by them during actual use. This article will introduce the test principle and application of the paper bag lifting fatigue tester in detail.
First, the test principle.
The test principle of the paper bag lifting fatigue tester is relatively simple, mainly by simulating the repetitive stress of the paper bag during actual use to evaluate the strength and durability of the paper bag. Specifically, the testing process is as follows:
Prepare the sample: Select the paper bag sample to be tested, and make sure that the paper bag is not damaged, crease-free, and in a flat state.
Fill the sample: Fill a mixture of particles equivalent to 2 times the amount of the nominal contents into a paper bag, ensuring that three-quarters of the bag is filled. This is done to simulate the load inside the paper bag during actual use.
Hanging the sample: Hang the filled paper bag on the fatigue testing machine to ensure that the carrying part of the paper bag is connected to the lifting device of the testing machine.
Set test parameters: Set fatigue test parameters such as the number of bag lifts or bag lifting time as needed. Typically, these parameters are set based on the number of times the paper bag is likely to be lifted during actual use.
Start the test: Start the fatigue testing machine and start the fatigue test on the paper bags. During the test, the fatigue tester repeatedly lifts the paper bag with set parameters.
Observation: After a certain number of lifting operations, the test is stopped. Observe whether the carrying point of the paper bag is damaged, torn, etc., to evaluate the strength and durability of the paper bag.
Through the above steps, we can use the paper bag lifting fatigue tester to perform a fatigue test on the paper bag, so as to understand the possible performance of the paper bag in the actual use process.
