Description

Technical Field

[0001] This utility model relates to the field of fabric stretch testing technology, specifically a fabric stretch testing device that is easy to fix. Background Technology

[0002] Depending on the intended use, different weaving methods are required for fabrics. Before cutting and using the fabric, its characteristics need to be tested, including its tensile properties. This testing requires specialized equipment. However, existing fabric tensile testing devices have certain shortcomings. Due to the lack of a proper fixing and limiting device to secure the fabric, it is easy for the fabric to fall off during the tensile testing process, making it inconvenient to use.

[0003] Patent CN217931144U discloses a fabric tensile testing device that is easy to fix. It is equipped with a bidirectional lead screw, a moving seat, and a bevel gear set. A servo motor drives the bidirectional lead screw to rotate through the bevel gear set, which in turn drives the moving seat at both ends of the bidirectional lead screw to move left and right. This makes it easy to fix the fabric for tensile testing. The length of the stretch can be clearly observed through the scales on both sides of the test platform, making the testing device more convenient to use.

[0004] In the aforementioned patent, the device solves the problems mentioned above. However, the device still has the following problems: during the use of the device, the first fixed platform and the second fixed platform need to be docked through the rotation of the rotating shaft to complete the limiting clamping of the fabric. The tightness of the clamping needs to be controlled by the rotation of the rotating shaft, which needs to be manually controlled. Manual rotation of the rotating shaft is easily affected by external factors, which can easily lead to the fabric not being clamped tightly, causing the fabric to detach or tear during the stretching process. This makes it difficult to accurately test the tensile strength of the fabric.

[0005] To address the aforementioned issues, innovative design based on the existing device structure is urgently needed. Utility Model Content

[0017] 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.

[0018] Example 1: In a specific embodiment, this utility model provides the following technical solution: a fabric stretch detection device that is easy to fix, such as... Figures 1-6 The basic operating procedure of the detection device is shown in the figure. The base plate 1 and the support plate 2 fixedly installed on the upper end of the base plate 1 are provided. The upper end of the support plate 2 is fixedly installed with an operating table 3, and two sets of sliding blocks 4 are slidably installed on the upper end of the operating table 3. A rotating shaft 8 is rotatably installed inside the sliding block 4, and a fixing plate 5 is fixedly installed on the outer side of the rotating shaft 8. A movable clamping plate 6 is slidably installed inside the rotating shaft 8, and a return spring 7 is provided at the lower end of the movable clamping plate 6.

[0019] When using this easy-to-fix fabric stretch testing device, the fabric to be tested needs to be placed on the upper end of the placement plate 18, with both ends of the fabric clamped inside the fixed plate 5 and the movable clamping plate 6. Then, the drive motor 12 can drive the output shaft 13 to rotate, so that the two sets of fixed plates 5 and movable clamping plates 6 move closer to each other and roll the fabric. After that, the two sets of fixed plates 5 and movable clamping plates 6 can move away from each other and stretch the fabric. The stretching effect of the fabric can be seen through the scale lines marked on the outside of the operating table 3, thus ensuring the ease of use of the device.

[0020] Example 2: In one specific embodiment, such as Figures 1-5 As shown, in order to solve the problem that existing devices are prone to slipping or tearing when clamping fabric, the automatic limiting process of the device for fabric is disclosed. The upper end of the operating table 3 is provided with a positioning structure for controlling the fabric. The return spring 7 is located inside the rotating shaft 8. The moving clamp 6 is located at the lower end of the fixed plate 5. An inclined clamp 16 is engaged on the outer side of the rotating shaft 8 and is slidably installed inside the sliding block 4. The positioning structure includes a drive motor 12, which is fixedly installed on the upper end of the operating table 3. An output shaft 13 is fixedly installed on the output end of the drive motor 12. The output shaft 13 is threadedly connected to two sets of sliding blocks 4, and the threads at both ends of the output shaft 13 are opposite in direction. The positioning structure also includes an electric telescopic rod 14, which is fixedly installed on the lower end of the operating table 3. A lifting rack 15 is fixedly installed on the upper end of the electric telescopic rod 14. A fixed shaft 9 is fixedly installed on the end of the rotating shaft 8 away from the fixed plate 5. A drive gear 11 is fixedly installed on the outer side of the fixed shaft 9, and a line indicator 10 is rotatably installed on the outer side of the fixed shaft 9. At the same time, the drive gear 11 meshes with the lifting rack 15.

[0021] When using this easy-to-fix fabric stretch detection device, both ends of the fabric need to be placed between the two sets of fixed plates 5 and the movable clamping plate 6. The fabric ends are clamped by the support of the return spring 7. During the forward rotation of the output shaft 13 driven by the drive motor 12, the two sets of sliding blocks 4 move closer together, allowing the fabric to be rolled up on the outside of the fixed plates 5 and the movable clamping plate 6. During this process, the drive gear 11 remains engaged with the lifting rack 15, causing the rotating shaft 8 to rotate inside the sliding block 4. This rotation of the rotating shaft 8 separates it from the tilting clamp 16, causing the tilting clamp 16 to move upwards inside the sliding block 4. The indicator 10 always points downwards, directly showing the corresponding fabric size. When the drive motor 12 stops driving the output shaft 13, the fabric stretches out. The distance indicated by the two sets of indicator lines 10 can be recorded at this time. Then, the electric telescopic rod 14 is retracted, causing the lifting rack 15 to move up and down and separate from the drive gear 11. This allows the drive motor 12 to drive the output shaft 13 to rotate in the opposite direction. The reverse rotation of the output shaft 13 will cause the two sets of sliding blocks 4 to move away from each other. At this time, the tilting clip 16 will engage with the rotating shaft 8 and limit the rotating shaft 8, causing the two sets of fixed plates 5 and moving clamps 6 wrapped with fabric to move away from each other and stretch the fabric. At this time, the stretching distance of the fabric can be seen, thus showing the stretching effect of the fabric. After the test is completed, the tilting clip 16 can be pulled to move the tilting clip 16 upward and separate from the rotating shaft 8, so that the rotating shaft 8 continues to rotate and the fabric can be removed, effectively improving the convenience of the device.

[0022] Example 3: Based on the above examples, such as... Figures 1-2 and Figure 6 The specific usage process of the lifting structure of the device is shown in the figure. The lower end of the control panel 3 is provided with a support structure for controlling the fabric. The support structure includes a shrink rod 17, which is fixedly installed on the upper end of the base plate 1. A placement plate 18 is fixedly installed on the upper end of the shrink rod 17, and a lifting frame 19 is fixedly installed on the lower end of the placement plate 18. A rotating screw 20 is installed on the internal thread of the lifting frame 19, and the rotating screw 20 is rotatably installed on the upper end of the base plate 1. A driven bevel gear 21 is fixedly installed on the upper end of the rotating screw 20, and a main bevel gear 22 is meshed with the outer side of the driven bevel gear 21. The main bevel gear 22 is fixedly installed on the outer side of the output shaft 13.

[0023] When using this easy-to-fix fabric stretch detection device, the output shaft 13 can be driven to rotate forward by the drive motor 12. The rotation of the output shaft 13 will drive the main bevel gear 22 to rotate synchronously. During the rotation of the main bevel gear 22, the driven bevel gear 21 that is meshed with it will also rotate. At this time, the rotating screw 20 at the lower end of the driven bevel gear 21 will rotate. The rotation of the rotating screw 20 will drive the placement plate 18 to move downward through the lifting frame 19, and the retraction rod 17 at the lower end of the placement plate 18 will retract, thereby facilitating the movement of the two sets of sliding blocks 4. At the same time, the placement plate 18 supports the fabric, which can prevent the middle position of the fabric from sinking, ensuring the accuracy of the fabric detection of the device and increasing the overall practicality.

[0024] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
