How to operate the carton compression testing machine, solve...

In the packaging industry, the stacking test of test cartons is very important, and how to operate the carton compression testing machine correctly is also very important! The steps to properly operate the carton compression testing machine are as follows:

1. Adjust the height of the upper and lower pressure plates according to the height of the sample, so that it is slightly larger than the height of the sample.

2. Select the working mode of conventional compressive test.

3. Press the "Test" button, and the upper pressure plate will go down until the specimen is crushed (or the preset maximum pressure value is reached in the compressive test 2 mode).

4. Change the sample and carry out the next test until a group of tests is completed.

Stacking test procedure.

Adjust the distance between the upper and lower pressure plates and place the specimen.

Set the stacking load, stacking time, and maximum deformation parameters.

Press the "Test" button to start the test until the set stacking test time is reached, or the deformation reaches the set allowable deformation, and the test is finished.

After a set of tests is completed, press the "Print" button to complete the printout of the test data.

Correctly operating the carton compression testing machine is the basic step of the test, but many personnel have not been able to grasp it well, the following Guangzhou standard packaging equipment **** technical personnel through the practical record, for you to summarize as follows:

1.First, determine the quality index standards for carton safety and pressure resistance and code.

The above two indicators can be obtained by the formula, the determination of the index depends on the domestic and foreign sales and storage period and there are differences, under special circumstances, such as the carton has the content of the support, according to the actual situation to determine the appropriate pressure index value, the quality index of the code must be determined by the formula.

2.Detection and processing status.

The carton is pretreated in a standard test state for 24 hours (general carton users can unconditionally go to an authoritative and impartial testing agency for testing) and then re-tested, so that the moisture of the carton can reach a dynamic equilibrium state.

3.Precautions for sample extraction.

In the trial production stage of new products, the difference between the printing and die-cutting strength of the sampling sample and the non-printing and die-cutting process is about 5-20%, so the state of the sample and the batch product should be basically consistent, and the sampling of the batch product should conform to the principle of statistical probability.

4.Judgment of the result.

If there is a box force value lower than the pressure resistance index of the carton detected in the standard state, it can be judged that the carton is unqualified, and the efficiency of the stacking test can be improved.

5.The test principle of carton compression testing machine.

The safety pressure resistance value of the same box is equal to the stacking quality value, and the minimum pressure resistance value of the sample is not less than the safety pressure resistance value.

6.Carton compression testing machine process and method.

Under standard atmospheric conditions: the maximum max and minimum min deviation of the same double corrugated box under handling, transportation, warehousing and other conditions are about 28, and the deviation value of a single corrugated box is about 33, (individual seriously damaged boxes should be excluded).

7.Determine the average value of the standard safety resistance to stress.

Then the average value of the standard safety pressure resistance of the double corrugated box should usually be the higher value of the safety pressure resistance than the safety pressure resistance value of 15), and the average value of the standard safety pressure resistance of a single corrugated box.

The arithmetic mean value of the peak pressure resistance of the sample carton is greater than the average value of the standard safety pressure resistance in the standard state, and the batch of cartons is qualified, and vice versa.

Please read the instruction manual of the testing machine carefully before operation to understand the performance parameters, structure and safe operation requirements of the testing machine.

Before using the testing machine, please confirm whether the voltage of the power supply family is stable to avoid the test data being inaccurate due to too high or too low electrical and land response voltage.

The testing machine should be placed on a stable ground to avoid shaking during use.

Before installing the specimen, please clean up the debris inside the testing machine to ensure the sensitivity of the testing machine.

Operators should pay attention to safety when using the testing machine to avoid safety accidents caused by the high-speed movement of the testing machine.

At the end of the test, please pay attention to the inside of the testing machine to avoid unnecessary troubles during the next test.

If you find that there is an abnormality in the testing machine, please stop using it immediately and ask a professional to overhaul it.
