Description

Technical Field

[0001] The utility model relates to the technical field of polyester yarn textile, in particular to a device for detecting the tensile strength of polyester yarns. Background Technique

[0002] The manufacturing process of polyester yarns includes four major processes: spinning, yarn dyeing, forming and packaging. A winding machine is mainly used as the production equipment. After the dyed yarns are formed and wound separately, reels wound with yarns are obtained. At present, as a widely used textile material, the detection of the tensile strength of polyester yarns is crucial for ensuring product quality. The existing detection of the tensile strength of polyester yarns usually uses a tensile testing machine.

[0003] For example, Chinese Patent CN109186834B discloses a device for detecting the tensile strength of textile yarns, which includes a placement mechanism and a detection mechanism. The detection mechanism is arranged on one side of the placement mechanism. The placement mechanism consists of a bottom plate, support columns, a fixed display board, fixed clamps and identification plates. At one end of the top of the bottom plate, two support columns are fixedly connected, and the top of the support columns is fixedly connected with a fixed display board.

[0004] The above device for detecting the tensile strength of textile yarns still has certain deficiencies. By setting a pressure sensor and a measuring cylinder, data can be accurately recorded by the pressure sensor during the detection process, which is convenient for data analysis and recording, and improves the accuracy of the detection results. The stretching length of the yarn can be recorded by the position of the measuring piston inside the measuring cylinder, providing multiple analysis data for the analysis of yarn detection data. However, the fixation of the yarn needs to be carried out through a return spring. When performing a tensile test, it is easy to make the fixation during the tensile strength test not firm enough, reducing the practicability of the device for detecting the tensile strength of textile yarns. Summary of the Utility Model
