Carton quality inspection and detection method

Abstract

The invention discloses a carton quality inspection and detection method comprising the steps of carton printing, patch prefabricating, carton sampling, shape detection, slice cutting, gap filling, slice shape and position test, slice performance test and data processing. Slice marking lines are printed on all cartons, cartons are selected through sampling, and slice sampling is carried out at the marking lines. The quality, thickness, compressive strength and impact strength of slices are tested, and the quality and performance of all the cartons are judged through data processing. The quality of cartons is measured and detected in a simple and practical method. By adopting the method, the quality of cartons can still be effectively inspected and controlled under the condition that there is neither bursting strength test equipment nor drop test equipment in the factory.

Description

technical field [0001] The invention relates to the field of inspection and detection technology equipment, in particular to a carton quality inspection and detection method. Background technique [0002] The most common product packaging is cartons, which are widely used for various product packaging; therefore, the quality and performance testing of cartons has become a regular inspection and testing task for many carton manufacturers and carton users; Usually, enterprises need to conduct quality tests on incoming cartons. Important indicators to measure the quality of cartons include: burst strength (or ultimate pressure bearing capacity) test, static pressure resistance, drop test, size measurement, etc. [0003] In the prior art, carton manufacturers and users need to use special testing equipment for the carton burst strength test, static pressure resistance, and drop test, and test the indicators through the whole carton. The disadvantages are: first, it is a patented...

Problems solved by technology

[0003] In the prior art, carton manufacturers and users need to use special testing equipment for the carton burst strength test, static pressure resistance, and drop test, and test the indicators through the whole carton. The disadvantages are: first, it is a patented device The cost is expensive, and it is a general-purpose testing equipment, which is not suitable for the testing requirements of cartons of different specifications; secondly, in the process of carton testing, after the destructive test is carried out on the cartons, the cartons are scrapped and cannot be reused, and regular testing will cause A lot of waste of cartons; again, some tests, such as bursting strength, can only be tested with laboratory equipment, and professional equipment and technical personnel are needed to test. In practical applications, most (90%) factories do not have this equipment , that is, this test is blank, so the quality of the purchased cartons cannot be guaranteed, and the test will lead to the scrapping of the tested cartons; and for the drop test, it is not practical to inspect the initial incoming materials. In practical applications, the newly purchased cartons are often not packed in the production line. In this way, the test cannot be carried out without the actual packing of the product, and the test will also lead to the scrapping of the tested carton; for size measurement, only a ruler or a tape measure can be used to measure and inspect the carton’s external dimensions, and the material of the carton cannot be judged.
