Extension and tensile property detection device for pe film

Abstract

The invention relates to the technical field of extension tensile detection, in particular to a PE film extension tensile performance detection device which comprises a vertical supporting frame and further comprises an annular detection base which is arranged on the front side of the vertical supporting frame, an annular embedding groove is formed in the middle of the top face of the annular detection base in a surrounding mode, and an edge guide ring is arranged on the edge of the inner side of the annular detection base; the fixed pressing ring is arranged above the annular detection base in parallel, a clamping sealing ring is arranged in the middle of the bottom face of the fixed pressing ring in a surrounding mode, and the fixed pressing ring can move in the vertical direction. According to the invention, through the magnetic force generated by electrifying the stretching electromagnet, the detection ball pulls the PE film at the contact point under the action of the magnetic force to extend and deform downwards, and compared with the traditional test equipment which can only evaluate the tensile property in a specific direction through one-time test, the common complex stress state of'multidirectional stretching caused by point load 'in the practical application is directly simulated; the limitation that traditional mechanical clamp type equipment can only carry out single-shaft or limited double-shaft stretching tests is effectively overcome.
