Abstract: In the process of circulation, warehouse stacking and use, there are often falling impacts, etc. Drop shock is the biggest cause of product damage. Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd., a professional manufacturer of packaging material testing equipment, has developed a free fall test machine according to the national standard. The instrument is height-adjustable to meet various experimental conditions and can detect cartons and wooden boxes. , the preparation of bags and other product packaging anti-drop strength. The following small series briefly describes how the free fall test machine stone can detect the anti-drop impact strength of liquid packaging bags?
Why check the anti-drop impact strength of liquid bags?
With the development of e-commerce, from daily necessities to household appliances, to industrial production equipment and equipment, online ordering is realized. These products must be used in the packaging of cartons. In the case of liquid packaging bags, in order to enable the liquid bag to be delivered to the consumer in good condition, it is often through a large number of experimental tests to simulate the liquid packaging bag in the process of transportation, handling and stacking, etc. According to the experimental test results, the liquid packaging bag itself is improved in structure and packaging structure to ensure safe and non-destructive transportation of the product to the consumer. The free fall test machine of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. has important significance in detecting the impact resistance of liquid packaging bags.
Free fall test machine
The research on the drop of liquid packaging bags has been paid more and more attention by domestic liquid packaging bag manufacturers, especially the large liquid crystal touch display bottle liquid packaging bag screen. The following small series briefly describes the experimental method of the anti-drop impact strength of liquid packaging bags. The detailed steps are as follows:
First, the experimental project
The drop resistance of the liquid packaging bag was measured by the free fall tester of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd.
Second, experimental equipment;
1. Introduction to the instrument
The anti-drop impact strength of the liquid packaging bag was tested using the free fall tester DLJ-2000 of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. The free fall test machine is used to simulate the influence of the impact of the falling impact on the packaging, such as carton, wooden box and bag, and to identify the impact strength of the package and the rationality of the packaging design. The instrument can adjust a variety of test modes, such as nodes, faces, and cymbals, to simulate various impact environments. The free drop test machine DLJ-2000 test height is adjustable to meet various experimental conditions. It is the preferred test instrument for all quality inspection organizations, packaging manufacturers and enterprises.
2, technical parameters
The free fall tester uses an electronic mode of operation with one-button operation. The drop height is between 300mm and 1500mm. Sanquan Zhongshi can also be specially customized. It can be used in a wide range of applications. It can complete the test surface drop, corner drop and edge drop to simulate various impact environments.
Third, the experimental implementation standards
GB/T 4857.5 "Package Box Drop Test Method" specifies the main performance requirements of the experimental equipment used in the vertical impact test of transport packages.
Fourth, the style: a liquid packaging bag of an electrical company
V. Test principle: Lift the experimental sample to a predetermined height, then let it fall freely according to the predetermined state and collide with the impact table.
Sixth, the experimental process:
1. Lift the test sample to the desired drop height position and support it as intended. The difference between the lift height and the predetermined height shall not exceed ±2% of the predetermined height. The drop height is the distance between the lowest point of the test sample and the impact table when ready to release.
2. Release the experimental sample according to the following conditions:
(1) When the surface is dropped, the angle between the falling surface of the test sample and the horizontal plane is not more than 2°;
(2) When the edge is dropped, the angle between the falling edge and the horizontal plane is not more than 2°, and the error between the specified surface and the impact table on the test sample is not more than ±5° or 10% of the angle (to The large value is the standard), so that the gravity line of the test sample passes through the edge that is dropped;
(3) When the angle is dropped, the angle between the specified surface and the impact table on the test sample is not more than ±5° or 10% of the angle (whichever is greater), so that the gravity line of the test sample passes. The angle of the fall; regardless of the state and shape of the test sample, the gravity line of the test sample should pass through the fallen face, line, and point.
3. The difference between the actual impact speed and the impact speed at the time of free fall does not exceed ±1% at the time of free fall.
4. Check the damage of the package and contents according to the relevant standards or regulations after the test. And analyze the test results.
Seven, the experimental results:
The free fall test machine manufacturer Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. is based on the long-term, and provides customers with the most comfortable and safe products and services with sincere service.
The innovation of Sanquan Zhongshi is endless, and innovation should be changed.
