Description

Technical Field

[0001] This utility model relates to the field of knitted fabric testing technology, specifically to an auxiliary testing device for the elasticity of knitted fabrics. Background Technology

[0002] In existing knitted fabric elasticity testing processes, effective fixation of the knitted fabric is one of the key factors in ensuring the accuracy of the test results. Traditional knitted fabric elasticity testing devices often use a fixed pressure method when pressing the knitted fabric, which cannot flexibly adjust the pressing force according to the different materials, thicknesses, elasticity, and other characteristics of the knitted fabric. For some thin and highly elastic knitted fabrics, excessive pressing force may damage their original structure and affect the accuracy of elasticity testing; while for thicker and less elastic knitted fabrics, insufficient pressing force may cause the knitted fabric to slip during the testing process, which will also cause deviations in the test results. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary detection device for the elasticity of knitted fabric, comprising a base, with support frames fixedly installed on both sides of the top of the base, and electric telescopic rods fixedly installed on the inner sides of the support frames, a tension sensor fixedly installed at the output end of the electric telescopic rods, a movable frame fixedly installed at the tension end of the tension sensor, a receiving groove opened inside the movable frame, and an upper pressure plate and a lower pressure plate symmetrically installed inside the receiving groove, with an adjusting screw threaded onto the top of the upper pressure plate.

[0008] As a preferred embodiment, a connecting vertical rod is fixedly installed on the outer side of the top of the guide slide plate. The upper end of the connecting vertical rod is connected to the bottom of the tension end of the tension sensor, and the right side of the connecting vertical rod is connected to the moving frame through a rubber pad.

[0009] As a preferred embodiment, the bottom of the support frame is integrally formed with a fastening plate, the bottom of the fastening plate is connected to the top of the base by bolts, and the support frame is L-shaped and symmetrically installed on the top of the base.

[0010] As a preferred embodiment, the tension sensor is electrically connected to an external display device, and the display device is a terminal display screen.

[0019] 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.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figure 1 As shown, this utility model provides an auxiliary detection device for the elasticity of knitted fabrics, including a base 1. Support frames 2 are fixedly installed on both sides of the top of the base 1. Electric telescopic rods 3 are fixedly installed on the inner side of the support frames 2. A tension sensor 4 is fixedly installed at the output end of the electric telescopic rod 3. A movable frame 5 is fixedly installed at the tension end of the tension sensor 4. A receiving groove 6 is opened inside the movable frame 5. An upper pressure plate 8 and a lower pressure plate 9 are symmetrically installed inside the receiving groove 6. An adjusting screw 7 is threaded on the top of the upper pressure plate 8.

[0023] This technical solution enables bidirectional stretching via the electric telescopic rod 3, simulating more realistic usage scenarios. The tension sensor 4 at the output end of the electric telescopic rod 3 accurately measures the tension, providing reliable data for evaluating elastic performance. The upper and lower pressure plates within the movable frame 5, along with the adjusting screw 7, allow for flexible adjustment of the clamping force according to the characteristics of the knitted fabric, simplifying operation. The stable support structure formed by the base 1 and the support frame 2, along with reliable fixed connections between components, ensures the stability and service life of the device. Furthermore, its flexible adjustment function makes it adaptable to knitted fabrics of various materials, thicknesses, and elasticities, and it is compatible with different testing standards, making it widely applicable.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, the bottom of the upper pressure plate 8 is bonded with a rubber anti-slip pad 10, the end of the upper pressure plate 8 slides in contact with the inside of the receiving groove 6, and the upper end of the adjusting screw 7 extends through to the top of the movable frame 5 and is fixedly installed with a handle; the lower pressure plate 9 is fixed inside the receiving groove 6, the inside of the mounting end of the lower pressure plate 9 is provided with a through groove 11, and the top of the lower pressure plate 9 is provided with anti-slip texture.

[0026] Adopting such Figure 1The technical solution shown allows the rubber anti-slip pad 10 to closely adhere to the surface of the knitted fabric when it is pressed, increasing the friction between the pad and the fabric. This effectively prevents the fabric from slipping during stretching, ensuring that the tension data measured by the tension sensor 4 accurately reflects the elastic properties of the knitted fabric. This avoids detection errors caused by fabric slippage, thereby improving the accuracy of the detection results. The anti-slip texture on the top of the lower pressure plate 9 further enhances the anti-slip effect on the knitted fabric. The anti-slip texture increases the contact area and friction with the fabric, working in conjunction with the rubber anti-slip pad on the upper pressure plate 8. The upper and lower pressure plates 8 and 9 work together to firmly clamp the knitted fabric from both above and below, ensuring that the fabric remains in a fixed position throughout the tensile testing process, thus providing a strong guarantee for accurate testing of the fabric's elasticity. The slot 11 on the lower pressure plate 9 makes the installation process of the knitted fabric much simpler. The operator only needs to easily pass one end of the knitted fabric through the slot 11 and then clamp and fix it using the upper pressure plate 8 and the lower pressure plate 9. Compared with a design without the slot 11, there is no need for complex positioning and adjustment, which greatly saves installation time and improves the efficiency of the preliminary preparation for the testing work.

[0027] Secondly, in the technical solution, guide rails 12 are fixedly installed on both the front and rear sides of the top of the base 1, and guide slide plates 13 are slidably installed on the surface of the guide rails 12. The top of the guide slide plates 13 is connected to the bottom of the movable frame 5. A connecting vertical rod 14 is fixedly installed on the outer side of the top of the guide slide plates 13. The upper end of the connecting vertical rod 14 is connected to the bottom of the tension end of the tension sensor 4, and the right side of the connecting vertical rod 14 is connected to the movable frame 5 through a rubber pad.

[0028] Its adoption is as follows Figure 1 The technical solution shown allows the guide slide plate 13 to slide smoothly along the guide rail 12 during the stretching of the knitted fabric by the electric telescopic rod 3 driving the moving frame 5. This effectively prevents the moving frame 5 from swaying or deviating to the left or right, ensuring that the moving frame 5 moves in a straight line in the horizontal direction. This allows the stretching force to be applied evenly to the knitted fabric, improving the force transmission accuracy during the detection process and ensuring the accuracy and reliability of the detection results.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-4 As shown, a fastening plate 15 is integrally formed and installed at the bottom of the support frame 2. The bottom of the fastening plate 15 is connected to the top of the base 1 by bolts. The support frame 2 is L-shaped and symmetrically installed on the top of the base 1. The tension sensor 4 is electrically connected to an external display device, which is a terminal display screen.

[0031] Using the above technical solution, the tension sensor 4 is electrically connected to an external terminal display screen, which can transmit the detected tension data to the display screen in real time for display. Operators can intuitively observe the changes in tension of the knitted fabric during the stretching process without having to perform additional complicated operations to obtain data. This greatly improves the detection efficiency and makes it convenient for operators to keep track of the detection progress and results in a timely manner.

[0032] The working principle of this utility model is as follows: One end of the knitted fabric to be tested is placed in the receiving groove 6 of the movable frame 5, so that the knitted fabric is positioned between the upper pressure plate 8 and the lower pressure plate 9. Then, one end of the knitted fabric is passed through the through groove 11, with its bottom fitting against the lower pressure plate 9. As the handle rotates, the upper pressure plate 8 moves up and down within the receiving groove 6, following the rotation of the adjusting screw 7. When the upper pressure plate 8 moves downwards, its bottom rubber anti-slip pad 10 gradually contacts and presses against the upper surface of the knitted fabric. The pressing force of the upper pressure plate 8 on the knitted fabric can be adjusted according to the thickness, material, and other characteristics of the knitted fabric by adjusting the handle. After the knitted fabric is fixed in place, the electric telescopic rod 3 is activated. The contraction causes the tension sensor 4 to move in the contraction direction. As the moving frame 5 moves, the knitted fabric is gradually stretched. The tension sensor 4 detects the magnitude of the tension applied to the knitted fabric in real time during the stretching process and converts the tension data into an electrical signal. This signal is then transmitted to an external terminal display screen via an electrical connection. By observing the real-time tension data displayed on the terminal display screen and combining it with information such as the stretched length of the knitted fabric, the operator can analyze the elastic properties of the knitted fabric, such as elastic modulus, tensile strength, and elastic recovery rate. When the predetermined detection requirements are met or the knitted fabric is stretched to its limit, the operation of the electric telescopic rod 3 is stopped.
