A high-efficiency tensile strength testing device for composite bags

Abstract

This invention provides a high-efficiency tensile strength testing device for composite bags, relating to the field of composite bag testing technology. It includes an assembly mechanism that installs an appropriate number of pads according to usage requirements, ensuring the pads on the clamps effectively fix the composite bag. Removable pads are provided to simulate the stress area and location of the composite bag under tension, greatly improving the accuracy of measurement data. This solves the problem that existing testing devices only use a single-sized clamp throughout the tensile testing process, resulting in a constant contact area between the clamp and the composite bag. This makes it inadequate for simulating complex stress conditions that composite bags may encounter in real-world scenarios, and it cannot flexibly adjust the clamp size to accurately reproduce the differentiated stress conditions experienced by the composite bag under different working conditions, thus greatly limiting the accuracy of the test data in mapping actual application scenarios.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite bag detection, and particularly relates to a composite bag efficient tensile detection device. BACKGROUND

[0002] In the field of modern commodity packaging, composite bags are widely used due to their good barrier property, flexibility, printing adaptability and other advantages. Composite bags are usually composed of various film materials with different functions, such as plastic film, aluminum foil, paper, etc., to meet the requirements of different commodities for moisture-proof, fresh-keeping, light-proof, puncture-resistant packaging, etc. Common application scenarios of composite bags include food packaging, medicine packaging, chemical product packaging, etc. In the production process of composite bags, tensile strength, as a core performance indicator, is directly related to the reliability and safety of composite bags in subsequent handling, storage, transportation and actual use. Therefore, after completing the production process, each batch and each type of composite bag must be rigorously tested for strength characteristics by a professional tensile detection device to determine whether it meets the corresponding use standards and requirements.

[0003] However, there are some deficiencies in the current design of composite bag tensile detection devices:

[0004] Firstly, the existing detection device is only equipped with a single specification chuck during the entire tensile detection process, which means that the contact area between the chuck and the composite bag is constant. Therefore, when simulating the complex stress conditions that the composite bag may encounter in real-world scenarios, it is not flexible enough to accurately reproduce the different stress situations that the composite bag may encounter under different working conditions by adjusting the size of the chuck, thereby greatly limiting the ability of the detection data to accurately map the actual application scenarios.

[0005] Secondly, the current tensile detection device has obvious shortcomings in its functional system. It can only measure the maximum stress coefficient of the composite bag from the initial static state to the moment of being pulled apart, but in actual application scenarios, the composite bag often needs to carry a certain weight of goods and move with personnel or equipment. In this process, the composite bag is continuously stressed, and its durability and endurance performance are also crucial to ensuring the safety of the goods inside the package. However, the existing detection device lacks the ability to simulate such actual working conditions, and cannot effectively evaluate the endurance performance of the composite bag during dynamic use, resulting in a significant disconnect between the detection results and actual use requirements.
