Description

Technical Field

[0001] The utility model relates to the technical field of elastomer testing, in particular to an elastomeric testing device for thermoplastic elastomers. Background Technique

[0002] For the resilience test of elastomer materials, it is mainly to manually stretch the elastomer material by hand. After releasing, the resilience of the material is observed with the naked eye to judge the resilience performance of the elastomer material. The accuracy of the test is relatively low, and it is difficult to effectively guarantee the performance test. For example, the patent with the publication number CN215866154U discloses a resilience testing device for elastomer materials, including a resilience testing tooling. The resilience testing tooling is installed on a tensile testing machine. The resilience testing tooling includes a bottom plate. The bottom plate is arranged on the working platform of the tensile testing machine. A fixed pressing mechanism and a movable pressing mechanism for clamping the elastomer material are installed on the bottom plate, and the fixed pressing mechanism and the movable pressing mechanism are arranged correspondingly. A guiding pulley is also installed on the bottom plate, and the guiding pulley is arranged corresponding to the movable pressing mechanism. A traction rope is installed on the movable pressing mechanism, and the free end of the traction rope bypasses the guiding pulley and is connected to the traction component of the tensile testing machine. This device can stretch the elastomer mechanically, but during the stretching process, there is no protection structure for the elastomer, and the elastomer may break, resulting in the splashing of elastomer fragments, thus affecting the staff and testing equipment.
