Description

Technical Field

[0001] This utility model relates to the field of textile fabric testing technology, and more specifically, to a testing device for elastic fiber fabrics. Background Technology

[0002] Fiber fabric is a fabric made of fibers, which can be natural or man-made. Fiber fabric refers to fabric made from fibers (whether natural or synthetic) through a textile process. Fibers typically refer to linear substances whose length is more than a thousand times their diameter and which possess a certain degree of flexibility and strength.

[0003] Patent CN220144143U discloses a fiber fabric testing mechanism, including a testing device body. A protective box is fitted around the testing device body, and a door is fitted onto one side of the protective box. A placement pad is fixedly connected to the bottom of the door, and a rubber pad is fixedly connected to the side of the door near the testing device body. A rotating block is rotatably connected to the top of the protective box, and both ends of the rotating block are connected to the inside and outside of the protective box. A push rod is fixedly connected to the end of the rotating block located outside the protective box. This utility model relates to the field of fabric processing technology. This fiber fabric testing mechanism solves the problem that testing mechanisms require a testing port, but because the testing mechanism is exposed to the outside for a long time, dust and even cotton lint may fall in, leading to testing deviations during use.

[0004] Although the device has many beneficial effects, it still has the following problems: While the testing mechanism can solve the problem of testing deviations during use, the elasticity of fiber fabrics is one of the important indicators for measuring fabric quality. Elasticity directly affects the fit and comfort of garments and is an important basis for consumers to choose clothing. Existing fabric elasticity testing devices have the problem of poor fixation during the testing process. Poor fixation can cause the fabric to move or deform during the testing process, thus affecting the accuracy of the test results. This error may cause a large deviation between the test data and the actual value, resulting in inaccurate assessment of fabric elasticity. Utility Model Content

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] An elastic fiber fabric testing device includes a base 1, with two connecting plates 2 on the top of the base 1. One connecting plate 2 is fixedly connected to the base 1, and the other connecting plate 2 is slidably connected to the base 1. A fixing block 3 is fixedly connected to the top of each of the two connecting plates 2, and a pressure block 5 is provided on the outer side of each of the two fixing blocks 3. The device also includes:

[0028] The fabric fixing component, located between the connecting plate 2 and the pressure block 5, is used to fix the fabric.

[0029] The stretching assembly, located on the outer surface of the base 1, is used to stretch the fabric. The elastic fiber fabric to be tested is placed in the appropriate position between the two connecting plates 2, at which point a portion of the fabric will cover the rectangular groove 6.

[0030] Furthermore, the fabric fixing assembly includes a cylinder 4, a moving block 17, and a guide rail 18. Both fixing blocks 3 are arranged in an L-shape. The outer surfaces of the two fixing blocks 3 that are close to each other are fixedly connected to the guide rail 18. Both guide rails 18 are arranged in a T-shape. The outer surfaces of the two guide rails 18 are slidably connected to two moving blocks 17. The two moving blocks 17 are fixedly connected to the corresponding pressure blocks 5. The top of the two fixing blocks 3 is fixedly installed with a cylinder 4. The output end of the two cylinders 4 is fixedly connected to the corresponding pressure block 5. The PLC controller 11 starts the cylinder 4. The output end of the cylinder 4 pushes the pressure block 5 and its connected moving block 17 to slide along the guide rail 18.

[0031] Furthermore, the fabric fixing assembly also includes a rectangular groove 6, insertion holes 10, insertion posts 15, and pressure plates 16. Pressure plates 16 are fixedly connected to the outer surfaces of the two pressure blocks 5 that are close to each other. Two insertion posts 15 are fixedly connected to the bottom of each of the two pressure plates 16. Rectangular grooves 6 are opened on the top of each of the two connecting plates 2. Two symmetrically distributed insertion holes 10 are opened on the top of each of the two connecting plates 2. The two pressure blocks 5 are in movable contact with the corresponding rectangular grooves 6. The two insertion posts 15 are inserted into the corresponding insertion holes 10. The two pressure plates 16 are in movable contact with the top of the corresponding connecting plates 2 until the pressure plates 16 at the bottom of the pressure blocks 5 are in close contact with the fabric and are slightly pressed down. During this process, the insertion posts 15 will be inserted into the corresponding insertion holes 10 to ensure the stability of the pressure blocks 5 in the horizontal direction and prevent them from shifting during the stretching process. The design of the pressure plates 16 not only provides sufficient pressure to fix the fabric, but also further enhances the stability of the fixing through the cooperation of the insertion posts 15 at the bottom and the insertion holes 10.

[0032] Furthermore, the tensioning assembly includes a motor 9, an adapter block 12, and a threaded rod 14. Two connecting blocks are fixedly connected to the outer surfaces of both sides of the base 1. A threaded rod 14 is rotatably connected between the two connecting blocks on the same side. The motor 9 is fixedly installed on the outer surface of the connecting blocks. The output end of the motor 9 is fixedly connected to the threaded rod 14. An adapter block 12 is fixedly connected to the outer surfaces of both sides of one of the connecting plates 2. Both adapter blocks 12 are located on the outer side of the base 1. One of the adapter blocks 12 is threadedly engaged with the corresponding cylinder 4. The PLC controller 11 then starts the motor 9. The motor 9 drives the threaded rod 14 to rotate. Since the adapter block 12 is threadedly engaged with the threaded rod 14, as the threaded rod 14 rotates, the adapter block 12 and one of the connecting plates 2 connected to it will move along the axial direction of the threaded rod 14.

[0033] Furthermore, a guide post 7 is fixedly connected between the two connecting blocks on the other side. The guide post 7 is slidably connected to another adapter block 12. The slidable connection between the guide post 7 and the other adapter block 12 ensures the stability of the connecting plate 2 during movement and avoids errors caused by shaking.

[0034] Furthermore, laser rangefinder 8 and tension sensor 13 are fixedly installed on the top of the two adapter blocks 12. PLC controller 11 is fixedly installed on the outer surface of the fixing block 3. Laser rangefinder 8 and tension sensor 13 are wirelessly connected to PLC controller 11. Motor 9 is controlled by PLC controller 11. PLC controller 11 calculates key performance indicators such as elastic modulus and breaking strength of the fabric based on the received data.

[0035] Working Principle: When the operator needs to use this elastic fiber fabric testing device, firstly, the elastic fiber fabric to be tested is placed in an appropriate position between the two connecting plates 2. At this time, part of the fabric will cover the rectangular groove 6. Then, the PLC controller 11 starts the cylinder 4. The output end of the cylinder 4 pushes the pressure block 5 and its connected moving block 17 to slide along the guide rail 18 until the pressure plate 16 at the bottom of the pressure block 5 is in close contact with the fabric and slightly presses down. During this process, the insertion post 15 will be inserted into the corresponding insertion hole 10 to ensure the stability of the pressure block 5 in the horizontal direction and prevent it from shifting during the stretching process. The design of the pressure plate 16 not only provides sufficient pressure to fix the fabric, but also further enhances the stability of the fixation through the cooperation of the insertion post 15 at its bottom with the insertion hole 10. After the fabric is fixed, the PLC controller 11 receives the instruction to start testing. The controller 11 then starts the motor 9, which drives the threaded rod 14 to rotate. Since the adapter block 12 is threadedly connected to the threaded rod 14, as the threaded rod 14 rotates, the adapter block 12 and its connected connecting plate 2 will move along the axial direction of the threaded rod 14. The sliding connection between the guide post 7 and the other adapter block 12 ensures the stability of the connecting plate 2 during movement, avoiding errors caused by shaking. As the connecting plate 2 moves, the fabric is gradually stretched. During this process, the laser range sensor 8 measures the moving distance of the connecting plate 2 in real time, i.e., the stretching length of the fabric, and transmits the data to the PLC controller 11. At the same time, the tension sensor 13 measures the tension force on the fabric during stretching and transmits the data to the PLC controller 11. Based on the received data, the PLC controller 11 calculates the key performance indicators of the fabric, such as the elastic modulus and breaking strength.
