Description

Technical Field

[0001] The utility model relates to the technical field of latex threads, in particular to an online tensile testing device for latex threads. Background Art

[0002] Latex is a natural rubber obtained from the sap of rubber trees. It is extremely precious because each rubber tree can only produce 30 ml of latex juice per day. It takes at least one to one and a half days to make a latex product. It is a very time-consuming and precious product. In the later processing, latex is used as the main raw material, plus other industrial raw materials; after the latex is produced, it needs to be tested for tensile properties using a tensile device.

[0003] According to the Chinese patent authorization announcement number CN 217819732 U, a tensile testing machine for latex thread physical property testing is provided, which includes: a mounting plate; a fixing assembly, the bottom of the fixing assembly is fixedly connected to the left side of the top of the mounting plate, the fixing assembly includes a mounting frame, the bottom of the mounting frame is fixedly connected to the left side of the top of the mounting plate, the top of the mounting frame is fixedly connected to a rotating member, the inner side of the rotating member is rotatably connected to a threaded sleeve, and both sides of the threaded sleeve are fixedly connected to a rotating rod. The utility model provides a tensile testing machine for latex thread physical property testing, which drives the threaded rod to move downward by the rotation of the threaded sleeve, and the movement of the threaded rod drives the pressure plate to move downward, thereby fixing one side of the latex thread, and the operation is very convenient, which is convenient for fast fixing of the latex thread, and greatly facilitates batch testing;

[0004] This application realizes the limiting fixation of the latex thread by manually rotating the rotating rod to drive the pressure plate to move. The manual fixation method is cumbersome and inconvenient, and the subsequent replacement and inspection of the latex thread requires the rotating rod to be rotated in the opposite direction and re-fixed, which is time-consuming and labor-intensive. At the same time, the subsequent stretching test still requires manual rotation of the rotating disk, which greatly reduces the efficiency of the latex thread stretching test. Utility Model Content
