TECHNICAL FIELD
[0001] The utility model relates to sealing washer production technical field especially relates to a sealing washer production is with tension testing device. BACKGROUND
[0002] In the bottle cap production industry, the quality of the bottle cap sealing washer directly concerns the sealing property and shelf life of the product, thereby having a significant influence on the quality and market competitiveness of the whole product. As one of the key indicators for evaluating the quality of the bottle cap sealing washer, the precise detection of the tensile performance is extremely important. If the tensile force of the sealing washer is insufficient, the sealing washer is prone to rupture, separation and other conditions due to bearing external force during the storage and transportation of the product, leading to sealing failure of the bottle cap and causing serious problems such as product leakage and deterioration. Not only will this cause economic losses, but also may damage the reputation of the enterprise.
[0003] The traditional sealing washer tensile testing method has many defects. Some common methods only apply force to a certain part of the washer, and a simple single-end stretching method is used. The washer is prone to local deformation or even tearing near the force application point. The tensile value obtained by testing cannot reflect the true tensile resistance of the washer when it is uniformly stressed as a whole. This makes the washer unevenly stressed, and it is impossible to accurately simulate the all-around tensile conditions that the washer bears in the actual use scenario, thereby leading to a large deviation between the test results and the true performance. Therefore, a sealing washer production tension testing device is proposed to solve the above problems. UTILITY MODEL CONTENTS
