Textile fabric elasticity detection device

Abstract

This utility model discloses a textile fabric elasticity testing device, relating to the field of fabric elasticity testing technology. It includes a base plate, with a first motor fixedly connected to one side of the top of the base plate. A take-up / release roller is fixedly connected to the output end of the first motor. A guide roller is located on one side of the take-up / release roller at the top of the base plate. Using this structure, the second motor drives a small gear to rotate, which in turn drives a large gear to rotate. The large gear then drives a first lead screw to rotate, causing a first screw block to slide in a first groove. This causes the first screw block to move a movable seat, which in turn moves a fixed component at that location. This, in conjunction with the fixed component at the fixed seat, tightens the fabric, preventing wrinkles and more accurately reflecting the fabric's elasticity. It reduces testing errors caused by uneven fabric texture and can achieve flatness testing for both soft, wrinkle-prone and highly elastic fabrics.

Description

Technical Field

[0001] This utility model belongs to the field of fabric elasticity testing technology, and specifically relates to a textile fabric elasticity testing device. Background Technology

[0002] Textile fabrics refer to sheet-like materials made from natural fibers such as cotton, linen, silk, wool, and chemical fibers such as polyester, nylon, and acrylic fibers, or blends of natural and chemical fibers, through a series of processing techniques such as spinning, weaving, dyeing, and finishing. They are the basic materials for many fields such as clothing, home textiles, and industrial fabrics. Elasticity is an important performance indicator of textile fabrics, which has a profound impact on their performance and wearing experience. Therefore, elasticity testing is essential and requires the use of elasticity testing equipment.

[0003] For example, Chinese patent CN215179235U discloses a textile fabric surface elasticity testing device. The textile fabric surface elasticity testing device includes a base plate, a support plate is provided at the upper end of the base plate, a fixed shaft is fixedly connected to one end of the support plate, an inclined plate is provided on the upper surface of the base plate near the support plate, and an L-shaped connecting block is provided at the upper end of the inclined plate.

[0004] Although the aforementioned patent has solved the problem that it is difficult to flatten the fabric surface when manually pressing it, and that the fabric is easily pressed with different tensions after being pressed by the pressing mechanism, resulting in inaccurate test results of the fabric surface elasticity, there are still some defects that need to be improved. The positions of the two pressing plates in the device are relatively fixed and cannot play a role in tightening the fabric. During the test, since the pressing plates cannot actively tighten the fabric, the fabric is prone to loosening and wrinkling in the pressing area, which is not convenient for the fabric to be tested. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a textile fabric elasticity testing device to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A textile fabric elasticity testing device includes a base plate. A first motor is fixedly connected to one side of the top of the base plate, and a take-up and release roller is fixedly connected to the output end of the first motor. A guide roller is provided on one side of the top of the base plate near the take-up and release roller. A first power assembly is provided on the side of the base plate away from the take-up and release roller. A movable seat is slidably connected to the base plate through the first power assembly. A fixed seat is fixedly connected to the side of the base plate near the guide roller. A fixing assembly is provided on one side of the fixed seat and the movable seat. A second electric push rod is provided on the top of the base plate between the fixed seat and the movable seat. An elastic force gauge is fixedly connected to the top of the second electric push rod. A second power assembly is provided on one side of the second electric push rod.

[0008] As a preferred technical solution, the fixing component includes a first electric push rod, which is fixedly connected to both sides of the fixed seat and the movable seat. A pressure plate is fixedly connected to the top end of the first electric push rod, and a support plate is fixedly connected to one side of the top end of the fixed seat and the movable seat.

[0009] As a preferred technical solution, the first power assembly includes a second motor, which is fixedly connected to one side of the base plate. A small gear is fixedly connected to the output end of the second motor, and a large gear is meshed with one side of the small gear. A first lead screw is fixedly connected to one side of the large gear, and a first screw block is threaded onto the outer surface of the first lead screw. One side of the first screw block is fixedly connected to one side of the movable seat. A first sliding groove is formed at the top of the base plate below the movable seat. The first lead screw is rotatably connected inside the first sliding groove, and the first screw block is slidably connected inside the first sliding groove.

[0010] As a preferred technical solution, limit grooves are formed on both sides of the inner side of the first slide groove, and limit blocks are slidably connected inside the limit grooves. One side of the limit block is fixedly connected to one side of the first screw block.

[0011] As a preferred technical solution, a second slide groove is provided on both sides of the inside of the first slide groove on the base plate, and a pulley is slidably connected inside the second slide groove. The pulley is fixedly connected to the bottom end of the movable seat.

[0012] As a preferred technical solution, the second power assembly includes a fixed frame, which is fixedly connected to one side of the base plate located on the fixed seat. A third motor is fixedly connected to one side of the fixed frame, and a second lead screw is fixedly connected to the output end of the third motor. A second screw block is threadedly connected to the outer surface of the second lead screw, and the second screw block is slidably connected to the fixed frame. The second electric push rod is fixedly connected to the second screw block.

[0013] In summary, the present invention has the following main advantages:

[0014] Firstly, this utility model utilizes a second motor to drive a small gear to rotate, which in turn drives a large gear to rotate, and the large gear drives a first lead screw to rotate. This drives a first screw block to slide in a first sliding groove, thereby causing the first screw block to move a movable seat. The movable seat then moves the fixing component at that location, which in turn works with the fixing component at the fixed seat to tighten the fabric, preventing wrinkles and more accurately reflecting the fabric's elasticity. This reduces detection errors caused by uneven fabric textures and enables flatness detection for both soft, wrinkle-prone and highly elastic fabrics that are easily deformed.

[0015] Secondly, this utility model, by opening a second sliding groove on the base plate, and having a sliding pulley in the second sliding groove, with the pulley installed under the movable seat, makes the sliding of the movable seat smoother, which can effectively avoid problems such as jamming or deviation of the movable seat, and is conducive to the efficient and smooth operation of the fabric tensioning work.

[0022] Example

[0023] refer to Figures 1 to 5The textile fabric elasticity testing device described in this embodiment includes a base plate 1. A first motor 5 is fixedly connected to one side of the top of the base plate 1. A take-up and untake-up roller 6 is fixedly connected to the output end of the first motor 5 for placing and taking up the fabric to be tested. A guide roller 7 is provided on one side of the take-up and untake-up roller 6 at the top of the base plate 1 to guide the fabric conveying. A first power assembly 8 is provided on the side of the base plate 1 away from the take-up and untake-up roller 6. A movable seat 3 is slidably connected to the base plate 1 through the first power assembly 8. A fixed seat 2 is fixedly connected to the side of the base plate 1 near the guide roller 7. A fixed assembly 4 is provided on one side of the fixed seat 2 and the movable seat 3. A second electric push rod 14 is provided at the top of the base plate 1 between the fixed seat 2 and the movable seat 3. An elastic force gauge 15 is fixedly connected to the top of the second electric push rod 14. A second power assembly 16 is provided on one side of the second electric push rod 14.

[0024] refer to Figure 1 The fixing component 4 includes a first electric push rod 41, which is fixedly connected to both sides of the fixed base 2 and the movable base 3. A pressure plate 42 is fixedly connected to the top of the first electric push rod 41, and a support plate 43 is fixedly connected to one side of the top of the fixed base 2 and the movable base 3. By setting the fixing component 4, the first electric push rod 41 drives the pressure plate 42 to move, so that the pressure plate 42 is close to the support plate 43, which can press down the fabric. It should be noted that rubber pads are fixed to one side of both the pressure plate 42 and the support plate 43 to increase friction resistance.

[0025] refer to Figure 1 , Figure 3 , Figure 4The first power assembly 8 includes a second motor 81, which is fixedly connected to one side of the base plate 1. A pinion 82 is fixedly connected to the output end of the second motor 81. A large gear 83 is meshed with one side of the pinion 82. A first lead screw 84 is fixedly connected to one side of the large gear 83. A first screw block 85 is threaded onto the outer surface of the first lead screw 84. One side of the first screw block 85 is fixedly connected to one side of the movable seat 3. A first sliding groove 9 is formed at the top of the base plate 1 below the movable seat 3. The first lead screw 84 is rotatably connected inside the first sliding groove 9, and the first screw block 85 is slidably connected... Inside the first slide groove 9; by setting the first power component 8, before testing, the second motor 81 drives the pinion 82 to rotate, the pinion 82 drives the large gear 83 to rotate, and the large gear 83 drives the first lead screw 84 to rotate under the action of deceleration and torque increase. Since the first lead screw 84 is threadedly connected to the first screw block 85, and the first screw block 85 is located in the first slide groove 9 and fixedly connected to the moving seat 3, the rotation of the first lead screw 84 causes the first screw block 85 to slide linearly along the axis of the lead screw in the first slide groove 9, thereby driving the moving seat 3 to move smoothly on the base plate 1, ensuring that it can drive the fixing component 4 to effectively tighten fabrics with different elasticity and texture.

[0026] refer to Figure 3 The first slide groove 9 has limit grooves 10 on both sides inside. Limit blocks 11 are slidably connected inside the limit grooves 10. One side of the limit block 11 is fixedly connected to one side of the first screw block 85. By setting the limit grooves 10 and the limit blocks 11, during the movement of the moving seat 3, the limit blocks 11 slide in the limit grooves 10 to limit the movement direction of the first screw block 85 and prevent it from deviating.

[0027] refer to Figure 3 The base plate 1 has a second slide groove 12 on both sides inside the first slide groove 9. A pulley 13 is slidably connected inside the second slide groove 12. The pulley 13 is fixedly connected to the bottom end of the movable seat 3. By setting the second slide groove 12 and the pulley 13, the movable seat 3 is assisted to slide smoothly.

[0028] refer to Figure 1The second power assembly 16 includes a fixed frame 161, which is fixedly connected to the base plate 1 on one side of the fixed seat 2. A third motor 162 is fixedly connected to one side of the fixed frame 161. A second lead screw 163 is fixedly connected to the output end of the third motor 162. A second screw block 164 is threadedly connected to the outer surface of the second lead screw 163. The second screw block 164 is slidably connected to the fixed frame 161. A second electric push rod 14 is fixedly connected to the second screw block 164. By setting the second power assembly 16, when performing elasticity testing on the fabric, the third electric push rod 162 can be adjusted according to the testing requirements. The machine 162 drives the second lead screw 163 to rotate. Since the second lead screw 163 is threadedly connected to the second screw block 164 and the second screw block 164 can slide on the fixed frame 161, the rotation of the second lead screw 163 drives the second screw block 164 to move linearly along the axis of the lead screw on the fixed frame 161, thereby driving the second electric push rod 14 and the elastic force gauge 15 at its top to move synchronously. When the elastic force gauge 15 moves to the target position, the third motor 162 is stopped and the second electric push rod 14 is started. The second electric push rod 14 extends, pushing the elastic force gauge 15 to contact the fabric and apply pressure to perform elasticity detection.

[0029] Operating principle and advantages: First, the textile fabric to be tested is placed on the take-up roller 6. The first motor 5 is started, driving the take-up roller 6 to rotate, causing the fabric to slowly unfold and pass through the guide roller 7. Under the guidance of the guide roller 7, one end of the fabric is fed into the fixing component 4 between the fixed seat 2 and the movable seat 3. Next, the first electric push rod 41 in the fixing component 4 is started. The first electric push rod 41 extends, driving the pressure plate 42 to move downward. Since rubber pads are fixed on one side of both the pressure plate 42 and the support plate 43, as the pressure plate 42 approaches the support plate 43, the rubber pads come into close contact with the fabric, using the increased frictional resistance to firmly press the fabric, completing the fabric fixing and clamping. Subsequently, the second motor 81 drives the pinion 82 to rotate, the pinion 82 drives the large gear 83 to rotate, and the large gear 83 drives the first lead screw 84 to rotate under the action of deceleration and torque increase. Since the first lead screw 84 is threadedly connected to the first screw block 85, and the first screw block 85 is located in the first sliding groove 9 and fixedly connected to the movable seat 3. The rotation of the first lead screw 84 causes the first screw block 85 to slide linearly along the axis of the lead screw in the first slide groove 9, thereby driving the moving seat 3 to move smoothly on the base plate 1. When the moving seat 3 moves to the appropriate position, it cooperates with the fixing component 4 at the fixed seat 2 to tighten the fabric. When the elasticity of the fabric is tested, according to the testing requirements, the third motor 162 drives the second lead screw 163 to rotate. Since the second lead screw 163 is threadedly connected to the second screw block 164 and the second screw block 164 can slide on the fixed frame 161, the rotation of the second lead screw 163 drives the second screw block 164 to move linearly along the axis of the lead screw on the fixed frame 161, thereby driving the second electric push rod 14 and the elastic force gauge 15 at its top to move synchronously. When the elastic force gauge 15 moves to the target position, the third motor 162 is stopped and the second electric push rod 14 is started. The second electric push rod 14 extends, pushes the elastic force gauge 15 to contact the fabric and apply pressure to perform elasticity testing.
