Description

Technical Field

[0001] This utility model relates to a mechanism for measuring the resilience of knitted fabrics, and specifically to a mechanism for measuring the resilience of knitted fabrics. Background Technology

[0002] Resilience of knitted fabrics is a key performance indicator that measures their ability to return to their original shape after being deformed under stress. It directly affects the wearing experience, durability, and product quality of the fabric. Accurate measurement of resilience is crucial for ensuring product quality, optimizing process parameters, and meeting market demands throughout the production, research and development, quality inspection, and application of knitted fabrics. Therefore, related measurement technologies have always been a focus of the textile industry.

[0003] Knitted fabrics often bear multi-directional composite forces in practical applications, but traditional devices are mostly unidirectional stretching, which cannot fully reflect the performance differences of the fabric in different directions. Furthermore, the pressing mechanism of traditional devices is mostly a fixed-height pressure plate or a manually adjustable flat plate, which cannot automatically adjust the pressure and height according to the thickness of the knitted fabric.

One purpose is to provide a bidirectional stretching function to solve the problem that traditional devices cannot simulate multi-directional forces. Another purpose is to solve the problem of poor flattening effect of the turntable device, so as to improve the measurement stability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A knitted fabric resilience measuring mechanism includes a measuring platform, a frame fixedly connected below the measuring platform, and a bidirectional stretching device and a flattening device fixedly connected above the measuring platform.

[0007] A further improvement of the present invention is that: a fixed base is fixedly connected to the bottom of the biaxial stretching device, two guide columns are fixedly connected to the right side of the fixed base, the other ends of the two guide columns are fixedly connected to the measuring platform, a slide table is slidably connected to the outer wall of the two guide columns, an electric push rod is fixedly connected to the left side of the slide table, and a fixed base is fixedly connected to the left side of the fixed base, and a fixed rod is fixedly connected to the left side of the fixed base. The fixed end of the electric push rod is fixedly connected to the fixed base.

[0008] A further improvement of the present invention is that: a fixed base three is fixedly connected in front of a fixed base one in the bidirectional stretching device; an electric push rod two is fixedly connected below an electric push rod one in the fixed base three; a slide table two is fixedly connected to the moving end of the electric push rod two behind the fixed base one; two guide posts two are fixedly connected to the rear of the fixed base one; and the other ends of the two guide posts two are fixedly connected to the measuring platform and slidably connected to the slide table two.

[0009] A further improvement of the present invention is that: a support frame is fixedly connected above both the slide table and the guide post, and a pressure plate is slidably connected below both support frames, with a handle bolt threadedly connected above the pressure plate.

[0010] A further improvement of the present invention is that: a second support frame is fixedly connected to the opposite side of each first support frame on the measuring platform; a third guide post is fixedly connected to the inner side of the second support frame; a second pressure plate is slidably connected to the outer wall of the third guide post; and an eccentric clamping handle is threadedly connected to the second support frame above the second pressure plate.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a mechanism for measuring the resilience of knitted fabrics. A fixed base is fixed to a measuring platform, and a guide post provides lateral sliding guidance for a slide table. An electric push rod is connected at its fixed end to a fixed base and at its movable end to the slide table. When energized, the push rod extends and retracts, causing the slide table to slide along the guide post, thus achieving lateral stretching or contraction of the fabric. The fixed rod enhances the stability of the fixed base and ensures stretching accuracy. A fixed base is fixed in front of the fixed base. The movable end of the electric push rod is connected to the slide table, and the guide post provides longitudinal sliding guidance for the slide table. When the electric push rod extends and retracts, the slide table slides along the guide post, achieving longitudinal stretching or contraction of the fabric. Combined with the lateral stretching structure, this forms a bidirectional stretching function, solving the problem that traditional devices cannot simulate multi-directional forces.

[0014] 2. This utility model provides a knitted fabric resilience measuring mechanism. A support frame three is fixed to a measuring platform, and a fixed base four supports an electric push rod three. The moving end of the electric push rod three is connected to a fixed base five, and a guide column four ensures its vertical movement. A transparent pressure plate rises and falls with the fixed base five. During measurement, it descends to a height that matches the fabric thickness, flattening wrinkles without interfering with the fabric's condition. The measured dimensions can be directly observed through the transparent pressure plate, ensuring accurate data and solving the problem of poor flattening effect of the turntable device.

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1As shown, this utility model provides a knitted fabric resilience measuring mechanism, including a measuring platform 1, a frame 4 fixedly connected below the measuring platform 1, and a bidirectional stretching device 2 and a flattening device 3 fixedly connected above the measuring platform 1. The measuring platform 1 serves as the supporting foundation, with the bidirectional stretching device 2 and the flattening device 3 respectively mounted above the platform. The frame 4 provides support for the flattening device. Each module is positioned and guided by guide columns, and an electric push rod provides power, ensuring that the stretching, clamping, and flattening actions are performed collaboratively on the same reference platform, providing an overall framework for subsequent modular actions.

[0024] like Figure 2 As shown, this utility model provides a technical solution: a fixed base 24 is fixedly connected to the lower part of the bidirectional stretching device 2. Two guide pillars 21 are fixedly connected to the right side of the fixed base 24. The other ends of the two guide pillars 21 are fixedly connected to the measuring platform 1. A slide table 22 is slidably connected to the outer wall of the two guide pillars 21. An electric push rod 23, the power source of the slide table 22, is fixedly connected to the left side of the slide table 22. A fixed base 26 is fixedly connected to the left side of the fixed base 24, and a fixed rod 25 is fixedly connected to the left side of the fixed base 26. The fixed end of the electric push rod 23 is fixedly connected to the fixed base 26. When the electric push rod 23 extends or retracts, it drives the slide table 22 to slide horizontally along the guide pillars 21, thereby achieving lateral stretching or contraction of the clamped fabric. The fixed rod 25 enhances the stability of the fixed base 26, ensuring that the power source does not shake during the stretching process.

[0025] like Figure 3 As shown, this utility model provides a technical solution: a bidirectional stretching device 2 has a fixed base 3 27 fixedly connected in front of a fixed base 1 24. The fixed base 3 27 has an electric push rod 217 fixedly connected below an electric push rod 1 23. The moving end of the electric push rod 217 is fixedly connected to a slide table 28 behind the fixed base 1 24. Two guide posts 29 are fixedly connected behind the fixed base 1 24. The other ends of the two guide posts 29 are fixedly connected to the measuring platform 1 and slidably connected to the slide table 28. The guide posts 29 provide longitudinal sliding guidance for the slide table 28. When the electric push rod 217 extends or retracts, the slide table 28 slides along the guide posts 29 to realize longitudinal stretching or shrinking of the fabric, which, together with the transverse stretching structure, forms a bidirectional stretching function.

[0026] like Figure 4As shown, this utility model provides a technical solution: a support frame 211 is fixedly connected above both the slide table 22 and the guide post 29. A pressure plate 210 is slidably connected below both support frames 211, and a handle bolt 212 is threadedly connected above the pressure plate 210. The support frames 211 above the slide table 22 and the slide table 28 press the fabric together through the slidably connected pressure plate 210. By rotating the handle bolt 212, the pressure plate 210 is pushed downward by the threaded transmission, pressing the fabric onto the slide table. The pressure can be finely adjusted by rotating the bolt a few times to adapt to fabrics of different thicknesses and avoid slippage during stretching.

[0027] like Figure 5 As shown, this utility model provides a technical solution: A second support frame 213 is fixedly connected to the opposite side of each first support frame 211 on the measuring platform 1. A third guide post 215 is fixedly connected to the inner side of the second support frame 213. A second pressure plate 214 is slidably connected to the outer wall of the third guide post 215. An eccentric clamping handle 216 is threadedly connected above the second pressure plate 214 on the second support frame 213. The second support frame 213 on the measuring platform 1 is arranged opposite to the first support frame 211. The third guide post 215 provides sliding guidance for the second pressure plate 214. When the eccentric clamping handle 216 is rotated, the eccentric shaft pushes the second pressure plate 214 downward along the third guide post 215, quickly pressing the fabric. The eccentric structure self-locks in the locking position, ensuring the fabric's fixed end is stable during stretching.

[0028] like Figure 6 As shown, this utility model provides a technical solution: the frame 4 includes a transparent pressure plate 46, a support frame 3 41 is fixedly connected above the measuring platform 1, a fixed seat 42 is fixedly connected to the top of the support frame 3 41, an electric push rod 3 43 is fixedly connected below the fixed seat 42, a fixed seat 5 45 is fixedly connected to the moving end of the electric push rod 3 43 below the support frame 3 41, and a plurality of guide posts 444 are fixedly connected around the electric push rod 3 43, each guide post 44 having... The transparent pressure plate 46 is slidably connected to the support frame 3 41, and is fixedly connected to each guide post 44. The support frame 3 41 is fixed to the measuring platform 1. The fixed seat 42 supports the electric push rod 3 43. The moving end of the electric push rod 3 43 is connected to the fixed seat 5 45. The guide post 44 ensures its vertical movement. The transparent pressure plate 46 rises and falls with the fixed seat 5 45. During measurement, it falls to a height that matches the fabric thickness, flattens the wrinkles, and does not interfere with the fabric state. The measurement dimensions can be directly observed through the transparent pressure plate 46 to ensure data accuracy.

[0029] The working principle of the knitted fabric resilience measuring mechanism will be explained in detail below.

[0030] like Figure 1-6As shown, the fixed base 24 is fixed to the measuring platform 1, and the guide post 21 on its right side provides a linear motion guide for the slide table 22. The fixed end of the electric push rod 23 is connected to the fixed base 26, and the moving end is connected to the slide table 22. After being powered on, the push rod extends and retracts, causing the slide table 22 to slide along the guide post 21, realizing lateral stretching or contraction. The stretching amount is precisely controlled by the push rod stroke. The fixed base 27 is fixed in front of the fixed base 24. The moving end of the electric push rod 217 is connected to the slide table 28, and the guide post 29 provides a longitudinal motion guide for the slide table 28. When the electric push rod 217 extends and retracts, the slide table 28 slides along the guide post 29, realizing longitudinal stretching or contraction. When bidirectional coordinated stretching is required, the electric push rod 217 is controlled to extend and retract. The synchronized action of the electric push rod 217 and the 3rd electric push rod can apply a combined lateral and longitudinal tension to the clamped fabric, simulating the multi-directional force state when wearing clothing. When it is necessary to clamp the moving end of the fabric, the support frame 211 above the slide table 22 and the slide table 28 is first pressed against the edge of the fabric by the sliding pressure plate 210. Then, the handle bolt 212 is rotated, and the pressure plate 210 is pushed downward by the thread transmission principle, pressing the fabric onto the slide table by pressure. The support frame 213 on the measuring platform 1 is set opposite to the slide table 22 and the slide table 28. The guide post 215 on its inner side provides vertical sliding guidance for the pressure plate 214. When it is necessary to clamp the fixed end of the fabric, the eccentric clamping handle 216 is rotated to push the pressure plate 214. Plate 214 moves downward along guide post 315, quickly pressing the fabric. Support frame 341 is fixed to measuring platform 1, and its top fixed seat 42 supports electric push rod 343. The moving end of electric push rod 343 is connected to fixed seat 545. The surrounding guide posts 44 pass through the guide holes of support frame 341, ensuring that fixed seat 545 moves only in the vertical direction. Transparent pressure plate 46 is fixed to guide post 44 and rises and falls synchronously with fixed seat 545. Before measurement, electric push rod 343 extends, pushing transparent pressure plate 46 down to a height matching the fabric thickness, using the pressure plate's own weight and the electric push rod's thrust to flatten the fabric wrinkles. After measurement, the push rod retracts, causing the pressure plate to rise and reset. During measurement, the two ends of the knitted fabric sample are first placed on the slide table. The fabric is pressed and fixed on the side and the fixed side. Then, the handle bolt 212 and the eccentric clamping handle 216 are rotated to press and fix the fabric through the pressure plate. Then, the transparent pressure plate 46 is driven to descend and press the fabric flat by the electric push rod 3 43. The initial length of the fabric is recorded. Then, according to the test requirements, the electric push rod 1 23 and the electric push rod 217 are controlled to extend individually or simultaneously, driving the slide table to move and stretch the fabric to the set length. The set length is maintained for a set time. After the stretching is completed, the electric push rod 1 23 and the electric push rod 217 retract to release the tension. The fabric naturally rebounds. The transparent pressure plate 46 remains flat to ensure that there are no wrinkles during the recovery process. After the rebound is stable, the length of the fabric after recovery is observed and recorded through the transparent pressure plate 46. The rebound rate is calculated to complete the resilience assessment.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
