A device for testing tensile resistance of recycled fiber needlepunch felt
By combining the design of an arc-shaped bracket, a rolling mechanism, and a longitudinal tensioning mechanism, the composite stress simulation of needle-punched felt during the use of roller blind insulation blankets was realized, solving the problem of inaccurate testing in existing devices and improving the accuracy and efficiency of test results.

Abstract
本发明涉及性能测试技术领域，具体提出了一种再生纤维针刺毡抗拉性测试装置，包括固定台、弧形托架、拉卷机构、驱动机构以及纵向拉伸机构，通过弧形托架、拉卷机构与纵向拉伸机构的协同配合，真实还原针刺毡作为温室卷帘保温被芯材在实际使用中的弧形铺设、卷绕拉扯的复合受力工况，精准模拟针刺毡在卷放过程中不同位置的往复拉扯受力，彻底解决传统测试装置仅能进行单一横向或纵向拉伸、与实际使用工况严重不符的问题；同时弧形托架、夹持组件、拉卷机构与驱动机构相配合对针刺毡的动态卷绕测试，模拟针刺毡在卷帘卷放过程中两端部受卷绕力动态撕扯以及上凸顶部中心位置受弧形两侧双向撕扯的复合受力场景，使得测试数据更贴合实际使用受力状态。
