Description

Technical Field

[0001] The utility model relates to the technical field of stretch yarn detection, in particular to a high-tenacity polyester fiber stretch yarn toughness detection mechanism. Background Art

[0002] The selection of a testing mechanism for the toughness of elastic wire is an important part of ensuring product quality and performance. The toughness test of elastic wire requires randomly selecting a certain number of samples from the produced elastic wire to ensure that the samples are representative. At the same time, ensure that the length, thickness and other parameters of the sample meet the test requirements, fix the sample on a tensile testing machine, and stretch it at a certain speed and force until the sample breaks. During this process, record the elongation, breaking force and other data of the sample. These data can be used to calculate the toughness indicators of the elastic wire, such as tensile strength and elongation.

[0003] However, when there are a certain number of elastic wire samples, the samples need to be fixed one by one, and the length between the two ends of the connection needs to be ensured to be consistent, which requires continuous testing. However, while fixing both ends of the sample, it is also necessary to keep the spacing between the two ends the same, which requires manual calculation or multiple fixation, and there is a certain degree of error, thus increasing the complexity of the operation, and improvements are made based on this.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a high-tenacity polyester fiber elastic yarn toughness detection mechanism, comprising a detection base 1, two sets of limit components 3 are arranged inside the detection base 1, and the two sets of limit components 3 are used to limit the elastic yarn;

[0027] A box 2 is also fixed to the outside of the detection base 1, and a hydraulic cylinder is installed inside the box 2. The output end of the hydraulic cylinder is used to pull a set of limit components 3 to tighten the elastic wire for easy operation;

[0028] The two groups of limit assemblies 3 are further provided with protective members 4 for sleeved on the outside of the elastic wire.

[0029] A connecting shaft 21 is fixed to the output end of the hydraulic cylinder. The connecting shaft 21 extends to the inside of the detection base 1, and a clamping plate 22 is fixed to the end of the connecting shaft 21. A detection gauge 23 is clamped on the clamping plate 22. The detection gauge 23 detects the pulling force to facilitate knowing the maximum force required.

[0030] One group of limit components 3 includes a sliding shaft 31 that can slide, and sliding grooves 11 are opened on both sides of the detection base 1. The sliding shaft 31 is clamped into the sliding groove 11, and one side of the detection table 23 is fixed to the sliding shaft 31. The sliding shaft 31 in the other group of limit components 3 is clamped with the sliding groove 11, which can make the limited elastic wire elongate and extend the elastic wire, and realize detection.

[0031] The limiting assembly 3 also includes two opposite clamping blocks 32 and a clamping end 33. The opposite sides of the two clamping blocks 32 are arranged in parallel, and one side of the two clamping blocks 32 is provided with a matching opening 321. The clamping end 33 is clamped in the matching opening 321. The end of the clamping end 33 is provided with a through hole 331 that is penetrated and set. The through hole 331 is used to limit the end of the elastic wire. The outer side of the clamping end 33 is also threadedly connected with an extruded threaded rod 332. The extruded threaded rod 33 2 extends into the through hole 331. Two clamping pieces 333 arranged opposite to each other are fixed at the end of the clamping end 33. The front end of the clamping piece 333 is straight and the rear end is inclined. The front end extends between the two clamping blocks 32. The two clamping pieces 333 are used to limit the elastic wire. When the elastic wire is pulled, the clamping piece 333 is squeezed with the clamping block 32, so that the two clamping pieces 333 can fit more closely, thereby clamping the elastic wire more firmly.

[0032] The opposite sides of the two clamping sheets 333 are roughened, and the clamping sheets 333 are elastic to achieve firm clamping.

[0033] The sliding shafts 31 of the two sets of limit assemblies 3 are both provided with clamping holes 34;

[0034] The protective member 4 includes a sleeve 1 41 and two sleeve 2 44. The lower end of the sleeve 1 41 is provided with an opening. The edge of the opening of the sleeve 1 41 is integrally formed with a clamping layer 42. The clamping layers 42 on both sides are squeezed against each other. Both ends of the sleeve 1 41 are provided with slits 43. The sleeve 2 44 is sleeved with the sleeve 1 41 through the slits 43. The lower end of the sleeve 2 44 is also open. A clamping rod 45 is fixed to the outer end of the sleeve 2 44. The clamping rod 45 is inserted into the clamping hole 34, so that the sleeves 2 44 at both ends are limited, which is convenient for stretching or shortening, and ensures that the elastic wire is located in the sleeve 1 41 and the sleeve 2 44.

[0035] The first sleeve 41 and the second sleeve 44 are made of transparent plastic, and the diameters of both are larger than the diameter of the elastic wire.

[0036] When in use, the two ends of the elastic wire are stretched and extended into the through hole 331, and then the extrusion thread rod 332 is used to squeeze the elastic wire to fix the elastic wire to a certain extent, and then the clamping end 33 is clamped into the matching opening 321, so that the matching opening 321 is used, and the elastic wire is pulled outward from between the two clamping pieces 333 and then passes through the two clamping blocks 32, and the clamping end 33 is clamped into the matching opening 321. The other end of the elastic wire is also arranged in the same way. In the process of pulling the limiting component 3 on one side, the clamping end 33 is subjected to tension, so that the squeezing force between the two clamping pieces 333 and the two clamping blocks 32 is increased, thereby improving the clamping force on the elastic wire to a certain extent, and preventing the elastic wire from falling off due to loose fixation;

[0037] Secondly, the end of the elastic wire is squeezed by the extrusion thread rod 332, so that the end of the elastic wire is limited, so that the elastic wire does not need to change its shape, and the lengths of multiple groups of samples can be controlled to be the same, thereby improving the detection accuracy;

[0038] Furthermore, by squeezing the elastic wire upward from the openings of the sleeve 1 41 and the sleeve 2 44, the elastic wire is clamped in the sleeve 1 41 and the sleeve 2 44. At the same time, through the clamping hole 34, the sleeve 1 41 and the sleeve 2 44 can change in length as the sliding shaft 31 moves, thereby preventing the elastic wire from breaking and causing injuries to the operator.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
