Description

Technical Field

[0001] The invention relates to the technical field of yarn tensile strength testing devices, in particular to a yarn tensile strength testing device for textile use. Background Art

[0002] Yarn is a kind of textile, which is processed into products of a certain fineness from various textile fibers. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short fiber yarn, continuous filament, etc.

[0003] The tensile strength of yarn is one of the important indicators to measure the quality of fabric. It determines the durability and stability of the fabric during use. Through the tensile strength test, we can understand the performance indicators of the yarn such as strength, elongation, elasticity, etc., which provides an important reference for the production of textiles.

[0004] The existing yarn tensile strength test method is usually tested by a yarn tensile testing machine. The yarn is passed through a guide groove and two ends of the yarn are respectively fixed with two clamps. One of the clamps has a tensile force sensor. The tensile force sensor pulls the yarn to test the tensile strength of the yarn. After the yarn is broken, the tensile force sensor stops. At this time, the data obtained on the tensile force sensor is calculated by the processor to obtain the yarn strength value. The above test needs to be repeated many times to determine the tensile strength of the yarn. Therefore, the yarn needs to be pulled, and the test needs to be continued and repeated many times.

[0005] When clamping the yarn, the tester needs to pass the yarn through two sets of clamps and fix both ends of the yarn. The yarn needs to be tested multiple times, which increases the number of test steps and affects the test efficiency.

[0006] In view of the above technical problems, the present invention provides a tensile strength testing device for textile yarns that can test multiple groups of yarns at the same time. Summary of the invention

[0035] As attached Figure 4 and attached Figure 5As shown, the yarn positioning assembly 6 includes a vertical mounting frame 601, the upper side of the vertical mounting frame 601 passes through the frame 1 and one side wall is fixedly installed with multiple groups of positioning clamps 602 from top to bottom with bolts, the upper side of the positioning clamp 602 is slidably provided with a positioning clamp 604, and the side of the positioning clamp 602 close to the positioning clamp 604 is respectively installed with multiple groups of biting teeth 603 and biting teeth 609, and multiple groups of biting teeth 603 are meshed with biting teeth 609, and the distance between each group of the positioning clamp 602 and the corresponding group of positioning clamp 604 on the upper side is the same, so that the biting teeth 609 on multiple groups of positioning clamps 604 can be meshed with the biting teeth 603 on the positioning clamp 602 at the same time, and a moving mechanism for driving multiple groups of positioning clamps 604 to move up and down at the same time is installed inside the vertical mounting frame 601;
