Why does the carton rupture tester need regular inspection?

Under the conditions specified by the standard sample method, the maximum tension that the paper or cardboard of unit width can withstand before breaking is expressed in S, and the unit is kn/mm.

The elongation, expressed in millimeters, of a sample when stretched to break is measured under the conditions specified in the standard test method. The elongation at break is then calculated as a percentage of the length of the sample before starting to stretch. The result is a decimal.

HD-A504-B automatic burst strength tester is suitable for compression and sustained compression tests of various packaging bodies. The test results can be used as an important reference for the height of the finished product packaging boxes in the factory or an important basis for the design of packaging boxes. Execute IS-L1004, L1018, L1031, K6328, P8131, P8112, ASTM-D2210, TAPPI T403, ISO2759-2001, GB/T1539 and other international standards, for factories and enterprises, technical supervision departments, commercial inspection institutions, scientific research institutions, universities and other departments to provide ideal testing and research equipment.

Product features of automatic burst strength tester:

1. High degree of automation, simple and convenient operation, safe and reliable;

2. Independent research and development software, the testing machine has automatic measurement, intelligent calculation function, statistics, and printing test results; during the experiment, the information such as compression and deformation is displayed in real time;

3. And has the function of data storage, large data storage;

4. High-speed micro-printer, high-speed printing, easy to use;

5. Fully transparent acrylic protective device, visual rupture process;

6. Chinese and English bilingual operating system, and can be switched at any time.

The process of regular inspection of the carton burst strength testing machine:

1. Whether the fasteners of each part of the testing machine, especially the nuts at the oil pipe joints are tightened;

2. Open the upper left cover of the fuel tank frequently to observe whether the oil in the fuel tank is sufficient;

3. Check whether the blade on the pendulum rod is on the knife bearing, whether the top of the force measuring piston is in the socket, and whether the small belt on the force measuring piston is broken;

4. Open the cover to check whether the hammer and the string are running normally, whether the back and forth movement of the toothed rod is blocked, and whether the pointer rotates sensitively;

5. After turning on the power, press the oil pump switch to check whether the running direction of the oil pump is consistent with the direction shown by the arrow;

6. Check whether the lower jaw lift limit switch can work, and whether the lower jaw motor wiring is correct;

7. Start the oil pump and move the pendulum rod by hand. When the active needle of the dial rotates and exceeds 3%~5% (full load), the oil pump should automatically stop.
