Technical Field
[0001] This utility model belongs to the technical field of polyester textured yarn, and in particular relates to a tension testing device for polyester textured yarn. Background Technology
[0002] Polyester is characterized by its resistance to chemicals and frequent washing, reducing fading and discoloration of clothing. Hotel uniforms, stonewashed denim, sportswear, and children's clothing are all made of polyester. During the random inspection of polyester, appropriate tension testing devices are needed to conduct quality testing on the polyester.
[0003] However, existing devices lack precise control over the polyester filaments, making it difficult to quickly inspect them during the filament feeding process. Furthermore, during sampling, the inability to quickly clamp the filaments causes them to slip out during testing, preventing further processing. Therefore, we provide a tension testing device for polyester textured yarn to address these problems. Utility Model Content
[0004] The purpose of this invention is to provide a tension testing device for polyester textured yarn. The device pushes the polyester textured yarn through a test column, thereby constantly detecting the stress generated by the polyester textured yarn. At the same time, the contact between the positioning block and the placement block ensures that the polyester textured yarn will not easily fall off when it is pulled.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figures 1 to 5 This utility model is a tension testing device for polyester textured yarn. The polyester textured yarn is pushed by the test column 2, so that the stress generated by the polyester textured yarn can be detected at any time. At the same time, the contact between the positioning block 3 and the placement block 102 ensures that the polyester textured yarn will not easily fall off when it is pulled.
[0028] Specifically, the abutment plate 1 has a test column 2 at its front end. A force sensor 201 is fixed at the middle of the front surface of the test column 2. A display screen 202 electrically connected to the force sensor 201 is fixed on the surface wall of the test column 2. Placement blocks 102 are fixed on the front side walls of the abutment plate 1 located to the left and right of the test column 2. A connecting plate 103 is fixed on the front side wall of the boundary plate directly above the placement block 102. A positioning block 3 is provided on the lower end face of the connecting plate 103.
[0029] The operation process of this embodiment is as follows: By setting and using the above structure, the polyester elastic yarn is connected to the force sensor 201, and its two ends are placed on the placement block 102. The positioning block 3 is controlled to connect with the upper surface of the placement block 102, thereby clamping the polyester elastic yarn. At this time, the test column 2 is controlled to move away from the abutment plate 1, and then the test block will control the force sensor 201 to push the polyester elastic yarn, so that the polyester elastic yarn is stretched and lengthened. At this time, the force sensor 201 constantly tests the stress generated by the polyester elastic yarn and displays the tested force through the display screen 202.
[0030] Example 2
[0031] Please see Figure 2 and Figure 3 Based on Example 1, the stability of the test column 2 movement process is ensured by limiting the push plate 204 by the calibration rod 4.
[0032] Specifically, a through hole 101 is provided in the middle of the corresponding test column 2 of the abutment plate 1. A moving rod 203 is fixed on the surface of the test column 2, passing through the inside of the through hole 101. A push plate 204 is fixed on the rear end face of the moving rod 203. Calibration holes 205 are provided on the side walls of the push plate 204 located above and below the moving rod 203. Two calibration rods 4 are fixed on the rear end face of the abutment plate 1, passing through the inside of the calibration holes 205 respectively. A baffle 401 is fixed on the rear end face of the calibration rod 4, which is connected to the rear end face of the push plate 204. A spring 402 is sleeved on the calibration rod 4, which abuts against the front end face of the push plate 204.
[0033] The operation process of this embodiment is as follows: the push plate 204 controls the moving rod 203 to move inside the through hole 101, which in turn pushes the test column 2 to move back and forth in front of the abutment plate 1. The push plate 204 slides along the calibration rod 4 through the calibration hole 205. The calibration rod 4 limits the push plate 204 to ensure the stability of the movement of the moving rod 203 and the test column 2. At the same time, when the push plate 204 moves towards the abutment plate 1, the push plate 204 will compress the spring 402. Therefore, when the push plate 204 is released, the spring 402 will directly push the push plate 204 to reset, thereby controlling the reset of the test column 2.
[0034] Example 3
[0035] Please see Figure 2 , Figure 4 and Figure 5 Based on Example 1, the use of screw 301, T-shaped rod 304 and T-shaped hole 303 ensures that the positioning block 3 can quickly and accurately connect with the placement block 102.
[0036] Specifically, a screw hole 104 is provided through the middle of the connecting plate 103. A screw 301 is fixed on the upper end face of the positioning block 3, which spirals through the inside of the screw hole 104. A rotating block 302 is fixed on the upper end face of the screw 301. The two ends of the polyester elastic yarn are respectively located at the upper ends of the two placement blocks 102, and the polyester elastic yarn passes around the force sensor 201. A T-shaped hole 303 is provided on the upper end face of the positioning block 3. A T-shaped rod 304 is fixed on the lower end face of the screw 301, which rotates and engages with the inside of the T-shaped hole 303.
[0037] The operation process of this embodiment is as follows: when it is necessary to control the positioning block 3 to press the polyester elastic yarn, the rotating block 302 is controlled to rotate. The rotating block 302 drives the screw 301 to move up and down inside the screw hole 104. Then the screw 301 drives the T-shaped rod 304 to rotate in the T-shaped hole 303, thereby driving the positioning block 3 to move, so as to ensure that the positioning block 3 can quickly and accurately connect with the placement block 102.
