Description

Technical Field

[0001] The present invention relates to the technical field of fabric testing, and in particular to a knitted fabric performance testing device and method. Background Art

[0002] Elasticity and elastic recovery performance are important indicators for measuring the quality of elastic knitted fabrics. In the existing technology, the elasticity of knitted fabrics is tested by an elasticity tester.

[0003] When testing the elastic properties of knitted fabrics using an existing elasticity tester, the two ends of the test knitted fabric are clamped by the clamps on the elasticity tester to test the original length. The clamps are then moved away from each other by sliding. After a period of time, the knitted fabric is removed and the current length is tested. Finally, the stretch rate is calculated to determine the elastic properties.

[0004] However, when the existing elasticity tester is used to test knitted fabrics, the knitted fabric can only be pulled along the length direction of the warp or weft of the knitted fabric, that is, it is pulled along the edge direction of the knitted fabric. However, when the knitted fabric is put into use, it will not only be pulled along the edge direction, but also pulled along the surface direction of the knitted fabric. Therefore, it is also necessary to test the elasticity of the knitted fabric in this direction. The method of clamping the end of the knitted fabric with a clamp and sliding it cannot be pulled along the surface direction of the knitted fabric, resulting in inaccurate test results for the knitted fabric.

[0005] Therefore, the present invention proposes a knitted fabric performance testing device and method to improve this problem. Summary of the Invention

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 - Figure 10 As shown, a knitted fabric performance testing device proposed in an embodiment of the present invention includes: The fixing member 2 is slidably mounted on the mounting plate 1, and the fixing member 2 is used to clamp the two ends of the knitted fabric. A limited sliding rod 3 is slidably mounted on the fixing member 2. A plurality of limited sliding holes 301 for accommodating the limited sliding rod 3 are provided on the mounting plate 1. The limited sliding holes 301 are provided on the mounting plate 1 along the length direction of the mounting plate 1, and the position of the fixing member 2 can be adjusted by inserting the limited sliding rod 3 into the limited sliding holes 301 at different positions. The fixing member 2 has two parts, and the two parts have the same structure. The parts used for clamping the knitted fabric are relatively arranged and symmetrically slidably mounted on the mounting plate 1. The fixing member 2 clamps and fixes the edge of the knitted fabric by clamping. By sliding the fixing member 2, the device can stretch the knitted fabric along the length direction of its warp or weft, that is, stretch it along the edge of the knitted fabric. For the convenience of description, this stretching method is set as edge stretching. Figure 1 The direction from A to B shown in FIG is set as surface stretching along the surface of the knitted fabric. Figure 1 The direction from C to D shown in ; The pusher 4 is mounted on the mounting plate 1. The pusher 4 includes a reverse screw rod 401 rotatably mounted on the mounting plate 1. A swivel is mounted on the mounting plate 1. The reverse screw rod 401 is rotatably connected to the swivel, so that the reverse screw rod 401 is rotatably mounted on the mounting plate 1. A motor is mounted on the mounting plate 1. Pulleys are mounted on the motor output shaft and the reverse screw rod 401. The pulleys are connected by belts, so that when the motor is started, the pulleys are driven to rotate by the belts, thereby driving the reverse screw rod 401 to rotate. Both ends of the reverse screw rod 401 are threadedly connected to sliding plates 402. When the reverse screw rod 401 rotates, the sliding plates are driven by the threaded fit. The movable plates 402 move closer to or away from each other, the sliding plates 402 slide in conjunction with the mounting plate 1, the sliding plates 402 are hinged with a hinged rod 403, the pushing member 4 further comprises a pushing rod 404, both ends of the pushing rod 404 are hinged with the hinged rods 403 on the two sliding plates 402, one sliding plate 402 is hinged with two hinged rods 403, the hinged rods 403 are located at both ends of the sliding plate 402, a rod body is installed at the end of the pushing rod 404, the rod body is hinged with the hinged rod 403, the length of the rod body is greater than or equal to the thickness of the hinged rod 403, so that the rod body can provide an installation position for the hinged rods 403 located on different sliding plates 402, the specific installation method is as follows Figure 2 As shown, two hinged rods 403 are provided on a sliding plate 402, so that when the hinged rod 403 pushes the push rod 404, it can be more stable. A groove is opened on the mounting plate 1, and a block is installed on the sliding plate 402 and is slidably inserted in the groove. The groove restricts the block so that when the reverse screw rod 401 rotates, it will not drive the sliding plate 402 to rotate together, thereby increasing the feasibility of the device. When performing an elasticity test on a knitted fabric, a portion of the knitted fabric is sampled as a test sample, and the knitted fabric is arranged into a relatively regular shape, such as a square or rectangle, by cutting or other means. The original length is measured, and one of the two ends of the knitted fabric is clamped by the fixing piece 2, and the knitted fabric is slid so that the knitted fabric is in a stretched state, and the sliding limit rod 3 is slid to be inserted into the sliding limit hole 301, and the sliding of the fixing piece 2 is fixed so that the knitted fabric can remain in a stretched state. At this time, the timing is started. When the test time is reached, the knitted fabric is removed, the existing length is measured, and compared with the original length, and the other two ends of the knitted fabric are clamped by the fixing piece 2 to repeat the above steps to perform a stretching test on it. After the test is completed, the existing length is measured and compared with the original length. When the knitted fabric needs to be stretched along the surface, the existing length of the knitted fabric is first measured, and the knitted fabric is stretched along the surface. After the two ends of the knitted fabric are fixed by the fixing member 2, the sliding limit rod 3 is inserted into the sliding limit hole 301 to limit the sliding of the fixing member 2. Then, the motor is started, so that the reverse screw rod 401 starts to rotate, thereby driving the sliding plate 402 to approach each other, so that the sliding plate 402 pushes the hinged rod 403 thereon, so that the end of the hinged rod 403 connected to the pushing rod 404 moves in the direction away from the mounting plate 1, so that the pushing rod 404 pushes the knitted fabric, so that the knitted fabric is stretched along the surface. At this time, the motor stops rotating. Since the sliding plate 402 and the reverse screw rod 401 are threaded together, the sliding plate 402 can be maintained in the position when the motor stops rotating, thereby allowing the knitted fabric to be maintained in a state of stretching along the surface. When the test time is reached, the knitted fabric is removed and the length is measured, and then compared with the existing length measured above. Compared with the prior art, a fixing part 2 is slidably installed on the mounting plate 1, and the two ends of the knitted fabric are clamped by the fixing part 2. After the fixing part 2 is slid, the sliding limit rod 3 is inserted into the sliding limit hole 301, so that the knitted fabric remains in a stretched state. After the two ends of the knitted fabric are clamped by the fixing part 2, the reverse screw rod 401 is rotated to make the reverse screw rod 401 drive the sliding plate 402 to approach each other, and then the sliding plate 402 drives the free end of the hinged rod 403 away from the mounting plate 1, and then the knitted fabric is resisted and stretched by the push rod 404. The device can stretch the knitted fabric from multiple directions, thereby increasing the detection effect of the elastic performance of the knitted fabric.

[0022] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the partial structure of the fixing member 2 is disclosed. The fixing member 2 includes a base plate 201 which is slidably mounted on the mounting plate 1. Figure 1From the main perspective, the base plate 201 is slidably mounted on the mounting plate 1 in the vertical direction. The two parts of the fixing member 2 each have a base plate 201, so that there are two base plates 201 on the mounting plate 1. The distance between the base plates 201 is increased or decreased by sliding the base plates 201, so that the knitted fabric is in a stretched state or in its original length after being connected to the fixing member 2. A movable plate 203 is slidably mounted on the base plate 201 via a sliding rod 204. Figure 1 The movable plate 203 is fixed on the base plate 201 in a sliding manner, and the sliding rod 204 passes through the movable plate 203, so that a hole is formed on the movable plate 203, and the sliding rod 204 slidably cooperates with the hole. When the movable plate 203 slides, it can only slide along the axis direction of the sliding rod 204. The base plate 201 is rotatably mounted with a threaded rod 202 that is threadedly connected to the movable plate 203. The axis of the threaded rod 202 is parallel to the axis of the sliding rod 204. The movable plate 203 is limited by the sliding rod 204, so that when the threaded rod 202 rotates, the movable plate 203 is limited by the sliding rod 204 so that the movable plate 203 will not rotate with the threaded rod 202, thereby making the threaded rod 202 able to drive the movable plate 203 closer to or away from the base plate 201 by rotation, and the sliding limit rod 3 is slidably mounted on the movable plate 203; When the device is in use, first rotate the threaded rod 202 to make the movable plate 203 away from the base plate 201, and after placing the end of the knitted piece between the movable plate 203 and the base plate 201, rotate the threaded rod 202 to make the movable plate 203 close to the base plate 201, so that the movable plate 203 and the base plate 201 clamp the knitted piece. When the other end of the knitted fabric is also connected by the above method, after the connection is completed, connect the knitted fabric to the fixed part 2, and then insert the sliding limit rod 3 into the sliding limit hole 301 to limit the sliding of the base plate 201, and then limit the sliding of the entire fixed part 2, so that the device can clamp and fix the knitted fabric.

[0023] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, a partial structure of the fixing member 2 is disclosed. A pressure plate 206 is slidably mounted on the base plate 201 through a connecting spring 205. A groove is provided on the base plate 201, and the pressure plate 206 is slidably mounted in the groove. One end of the connecting spring 205 is connected to the inner wall of the groove, and the other end is connected to the pressure plate 206. The side wall of the pressure plate 206 fits the inner wall of the groove, and the sliding direction of the pressure plate 206 is restricted by the inner wall of the groove, so that the pressure plate 206 can only slide in a straight line direction, which increases the pressure plate 206 when sliding. Stability, an extrusion plate 207 for extruding the pressure plate 206 is installed on the movable plate 203. When the extrusion plate 207 contacts the pressure plate 206, the connecting spring 205 is in a compressed state. For the convenience of subsequent description, the side of the movable plate 203 and the extrusion plate 207 facing the base plate 201 is set as an extrusion surface. The distance between the extrusion surface of the extrusion plate 207 and the base plate 201 is smaller than the distance between the extrusion surface of the movable plate 203 and the base plate 201, so that there is a height difference between the extrusion surface of the extrusion plate 207 and the extrusion surface of the movable plate 203; When the movable plate 203 and the base plate 201 clamp the knitted fabric, the extrusion plate 207 pushes the pressure plate 206, and the contact area between the movable plate 203 and the base plate 201 and the knitted fabric is increased by the extrusion plate 207 and the pressure plate 206, thereby increasing the friction between the device and the knitted fabric and thus increasing the fixing effect of the device on the knitted fabric. Moreover, since there is a step between the extrusion surface of the extrusion plate 207 and the pressure surface of the movable plate 203, when the movable plate 203 and the base plate 201 clamp the knitted fabric, the gap between the movable plate 203 and the base plate 201 and the gap between the extrusion plate 207 and the pressure plate 206 have an angle, so that the knitted fabric bends when clamped, so that the gap of the fixing part 2 is not a straight line. The angle can limit the knitted fabric by further increasing the friction. When the device slides and the knitted fabric is pulled by external force, the knitted fabric is restricted by the angle, which reduces the possibility of the knitted fabric separating from the fixing part 2 when being pulled.

[0024] like Figure 6 As shown, the specific structure of the sliding limit rod 3 is disclosed. The sliding limit rod 3 is slidably connected to the movable plate 203. A plate body is installed on the movable plate 203. A channel for accommodating the sliding limit rod 3 is opened on the plate body. The side wall of the sliding limit rod 3 is restricted by the inner wall of the channel, so that the sliding limit rod 3 can only slide in a straight line direction, which increases the stability of the sliding limit rod 3 when sliding. A limiting rod 302 is hinged on the sliding limit rod 3, and a contact plate 303 is installed on the movable plate 203. When the contact plate 303 conflicts with the limiting rod 302, the sliding of the sliding limit rod 3 on the movable plate 203 is restricted. Figure 1When the limit rod 302 is rotated, the position direction of the free end of the limit rod 302 in the vertical direction changes. In normal state, the limit rod 302 is affected by gravity so that the free end of the limit rod 302 droops. The limit rod 302 is located at the end of the limit rod 3 away from the limit hole 301. The limit rod 302 is installed in a hinged manner. Firstly, the free end of the limit rod 302 can be closer to the upper surface of the movable plate 203, so that the height of the contact plate 303 does not need to be too high. Secondly, when the limit rod 3 slides, the limit rod 302 can be pulled to form a handle, which increases the practicality of the limit rod 302. The mounting plate 1 may be provided with a scale for observing the length and for sliding the fixing part 2 so that the two base plates 201 are at an appropriate stretching distance. When the device is in use, the base plate 201 is initially slid. After the sliding is completed, the sliding limit rod 3 is inserted into the sliding limit hole 301. At this time, the movable plate 203 is moved closer to the base plate 201 to fix the knitted fabric. When the movable plate 203 approaches the base plate 201, the sliding limit rod 3 is inserted into the sliding limit hole 301 and is blocked by the inner wall of the sliding limit hole 301, so that the sliding limit rod 3 cannot be The movable plate 203 then slides in the direction close to the base plate 201, thereby causing the movable plate 203 to slide relative to the sliding limit rod 3 when sliding, and the movable plate 203 will drive the contact plate 303 to gradually approach the limiting rod 302 and contact the limiting rod 302, so that the contact plate 303 blocks the limiting rod 302, thereby limiting the sliding tendency of the sliding limit rod 3 away from the sliding limit hole 301, and limiting the sliding of the sliding limit rod 3 so that it can be more stably inserted in the sliding limit hole 301, thereby increasing the stability of the fixing part 2 when the device pulls the knitted fabric, and increasing the practicality of the device.

[0025] like Figure 3 、 Figure 4 and Figure 10 As shown, part of the structure on the base plate 201 is disclosed. An extension plate 5 is slidably installed on the base plate 201 by pulling a spring 8. A hook plate 6 is installed on the extension plate 5. A receiving hole 7 for accommodating the hook plate 6 is opened on the movable plate 203. An L-shaped structure is formed between the extension plate 5 and the hook plate 6. Figure 1 From the main perspective, the extension plate 5 is slidably mounted on the base plate 201 in the vertical direction. One end of the pull spring 8 is connected to the base plate 201, and the other end is connected to the extension plate 5. The pull spring 8 forces the extension plate 5 to slide upward. When the pull spring 8 is at its original length, the hook plate 6 is aligned with the receiving hole 7. A driving rod 21 is hingedly connected to the extension plate 5. The free end of the driving rod 21 is hingedly connected to the movable plate 203. When the movable plate 203 moves away from the base plate 201, the free end of the driving rod 21 moves away from the base plate 201 along with the movable plate 203. During this process, the angle of the driving rod 21 changes, and the driving rod 21 presses the extension plate 5 downward. When the movable plate 203 is opened, the extension plate 5 can drive the hook plate 6 to move to a position where it is not blocked by the movable plate 203. When the knitted fabric is cut and prepared for testing, a through hole for accommodating the hook plate 6 is opened at its end. When the knitted fabric is installed with the device, the movable plate 203 is away from the base plate 201 and the extension plate 5 is pressed downward by the driving rod 21, so that the extension plate 5 drives the hook plate 6 to move downward to a position where it is not blocked by the movable plate 203. After the through hole on the knitted fabric is hung on the hook plate 6, the threaded rod 202 is rotated to make the movable plate 203 close to the base plate 201. By pulling the spring 8 to reset and the driving rod 21 to push, the extension plate 5 drives the hook plate 6 and the knitted fabric to move. When the threaded rod 202 is rotated to make the movable plate 203 close to the base plate 201 to clamp the knitted fabric, the movable plate 203 accommodates the hook plate 6 through the accommodating hole 7, reducing the influence of the hook plate 6 on the clamping of the knitted fabric between the movable plate 203 and the base plate 201, thereby increasing the practicality of the device. When the hook plate 6 pulls the knitted fabric, the operator does not need to slowly insert the end of the knitted fabric between the base plate 201 and the movable plate 203, which makes the installation of the knitted fabric by the device more convenient, thereby increasing the convenience of the device when in use.

[0026] like Figure 2As shown, the structure on the push rod 404 is disclosed. The push rod 404 is equipped with a side frame 14. The side frame 14 is slidably equipped with a resistance rod 10 through a pressure spring 9. The side frame 14 is L-shaped, one end of which is connected to the rotating shaft of the push rod 404. The segment corresponding to the end is set as a blocking segment, and the projection of the other end is located on the push rod 404. The segment corresponding to the end is set as a mounting segment. The resistance rod 10 is used to resist the knitted fabric. The resistance rod 10 is installed on the mounting segment of the side frame 14. One end of the pressure spring 9 is connected to the resistance rod 10, and the other end is connected to the mounting segment of the side frame 14. The length of the blocking segment is greater than the diameter of the push rod 404. When in use, when the knitted fabric is clamped by the fixing member 2, the projection of the knitted fabric and the push rod 404 on the mounting plate 1 overlap. When the sliding plate 402 is in the initial position, the pushing rod 404 is only in contact with the knitted fabric. At this time, the two sides of the knitted fabric that are not clamped by the fixing member 2 are blocked by the blocking section of the side frame 14. In the process of placing the knitted fabric into the side frame 14, the interference rod 10 is first pulled so that the free end of the interference rod 10 is away from the pushing rod 404. After the knitted fabric is placed in the side frame 14, the interference rod 10 is released so that the interference rod 10 presses and resists the knitted fabric. The side frame 14 and the interference rod 10 limit the range of movement of the knitted fabric on the pushing rod 404, so that when the pushing rod 404 pushes the knitted fabric, the knitted fabric will not move to a position deviated from the pushing rod 404, causing the knitted fabric and the pushing rod 404 to be misaligned, thereby increasing the feasibility of the device. The outside of the push rod 404 is covered with a rubber sleeve 20, and the push rod 404 contacts the knitted fabric through the rubber sleeve 20. The rubber sleeve 20 is covered on the outside of the push rod 404, so that when the push rod 404 pushes the knitted fabric, the rubber sleeve 20 flexibly contacts the knitted fabric, reducing the possibility of damage to the knitted fabric caused by hard contact between the corners of the push rod 404 and the knitted fabric when pushing, thereby increasing the feasibility of the device.

[0027] like Figure 4 and Figure 9As shown, part of the structure on the base plate 201 is disclosed. A through groove 11 is provided on the base plate 201. In the above description, the base plate 201 accommodates the pressure plate 206 through the groove body. The through groove 11 is connected to the groove body. The pressure plate 206 is mounted with a connecting plate 12 that slides with the through groove 11. The pressure plate 206 is located below the base plate 201. The extrusion plate 207 is also located below the movable plate 203. The free end of the connecting plate 12 is located at the top of the base plate 201 through the through groove 11. The base plate 201 A vertical plate 13 is installed on it, and a connecting spring 205 is installed between the vertical plate 13 and the connecting plate 12. A through rod 15 for contacting the mounting plate 1 is installed on the connecting plate 12. A hole is opened on the vertical plate 13, and the through rod 15 is slidably inserted in the hole so that the free end of the through rod 15 is located on the side of the vertical plate 13 close to the mounting plate 1. When in use, when the pressure plate 206 is squeezed by the extrusion plate 207 to move toward the mounting plate 1, it drives the connecting plate 12 to slide in the through groove 11, so that the connecting plate 12 The through rod 15 is driven to move in the direction close to the mounting plate 1, that is, the base plate 201 and the movable plate 203 clamp the knitted fabric. When the base plate 201 and the movable plate 203 have completed clamping the knitted fabric, the through rod 15 contacts the mounting plate 1, restricting the sliding of the pressure plate 206. The connecting spring 205 is in a compressed state, and the pressure plate 206 is blocked in two directions by the through rod 15 and the extrusion plate 207, thereby increasing the stability of the pressure plate 206 in clamping the knitted fabric. In the process, the connecting spring 205 always generates a resistance force on the connecting plate 12 and the pressure plate 206, thereby reducing the gap between the pressure plate 206 and the extrusion plate 207, so that the pressure plate 206 and the extrusion plate 207 can better clamp the knitted fabric, thereby increasing the practicality of the device.

[0028] like Figure 4 and Figure 8 As shown, the specific structure of the extension plate 5 is disclosed. A limiting block 16 is installed on the side wall of the extension plate 5, and a limiting groove 17 for accommodating the limiting block 16 is opened on the base plate 201. Limiting blocks 16 are installed on both sides of the extension plate 5. The limiting blocks 16 are accommodated by the limiting groove 17 and blocked by the inner wall of the limiting groove 17. Firstly, the extension plate 5 can only slide on the base plate 201 in a straight line direction. Secondly, the tendency of the limiting block 16 to separate from the base plate 201 is limited by the inner wall of the limiting groove 17, which reduces the possibility of the extension plate 5 and the base plate 201 separating and falling off during use, thereby increasing the practicality of the device.

[0029] like Figure 6 and Figure 8As shown, a specific mechanism on the mounting plate 1 is disclosed. Plate bodies are installed at both ends of the mounting plate 1 in the length direction. The plate body located below acts as a base. The plate body is also used to shield the base plate 201. When the base plate 201 slides into contact with the plate body, it slides to the maximum value. A track plate 18 is installed on the mounting plate 1. A track groove 19 for accommodating the track plate 18 is opened on the base plate 201. The through rod 15 is used to interfere with the track plate 18. The base plate 201 accommodates the track plate 18 through the track groove 19, accommodates the track plate 18 through the inner wall of the track groove 19, and shields the inner wall of the track groove 19 through the side wall of the track plate 18, so that the base plate 201 can only slide linearly on the mounting plate 1, and the contact area between the base plate 201 and the mounting plate 1 is increased, thereby increasing the stability of the base plate 201 when sliding.

[0030] like Figure 11 As shown, the present application also provides a knitted fabric performance testing method, which is tested by the above-mentioned knitted fabric performance testing equipment, comprising the following steps: S1. After the knitted fabric is cut, the original length of the knitted fabric is measured; S2, clamping and fixing the knitted fabric by the fixing member 2, then deforming the knitted fabric by sliding the fixing member 2, and measuring a first deformation length of the knitted fabric; S3, deforming the knitted fabric by pushing the pushing rod 404, and measuring a second deformation length of the knitted fabric; S4. Calculate the first deformed length and the original length, and calculate the second deformed length and the first deformed length to calculate the stretching rate, and judge the elastic properties of the knitted fabric according to the stretching rate.
