Description

Technical Field

[0001] The present invention relates to the technical field of tensile detection, and specifically to a fabric tensile property detection device. Background Art

[0002] The generation of clothing pressure is closely related to the structural form of the human body surface, that is, the curvature of the contact part between the clothing and the human body, the elastic modulus of the skin and soft tissues, and the mechanical properties of the human skin and subcutaneous soft tissues. The clothing factors affecting clothing pressure mainly include the structure and size of the clothing, the clothing quality, and the performance of the clothing fabric, etc. During the process of wearing clothing by the human body, the generation of pressure is the result of the comprehensive action of the multi-dimensional deformation of the clothing fabric, and is directly related to various properties of the fabric, such as the tensile elasticity, shear property, bending property, etc. of the fabric.

[0003] In the prior art, for the detection of the tensile property of the fabric, it is necessary to cut a certain length of the fabric, clamp both ends of the fabric with a tensile machine and then conduct a tensile test. However, because the fabric itself is a soft material, when clamping both ends of it, the fabric in the middle part is prone to relaxation, bending and wrinkling, thus affecting the accuracy of the tensile property test of the fabric. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a fabric tensile property detection device to solve the problems raised in the above background art. The structure of the present invention is novel. Both ends of the fabric are installed on the vertical frame, and the detection length can be freely adjusted. The clamping assembly clamps and fixes both ends of the detected length of the fabric, and through the movement of the mounting shaft, the fabric at the detection position is kept in a tight and flat state. The clamping assembly cooperates with the driving assembly and the side plate stretching assembly can respectively detect the tensile properties of the fabric in the transverse and longitudinal directions, and the detection is more convenient and has higher accuracy.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A fabric stretching performance detection device includes a base. Two vertical frames are symmetrically arranged on the top of the base, and two sliding grooves are formed on the surface of the base. The bottom of the vertical frame slides along the sliding groove. An installation shaft is installed inside the vertical frame. A fabric body is installed between the two installation shafts. A clamping component is arranged on one side of the vertical frame. The clamping component includes a lower clamping plate and an upper clamping plate. The upper clamping plate and the lower clamping plate are in pressing contact with the top and bottom of the fabric body. The two ends of the upper clamping plate are rotatably installed with locking bolts, and the upper clamping plate and the lower clamping plate are locked and connected by the locking bolts. A driving component is arranged on the middle surface of the base. The driving component includes two winding rods. Two winding rods are symmetrically and rotatably installed on the middle surface of the base through bearing seats. The two ends of the winding rod are fixed with winding shafts. A pulling rope is wound on the winding shaft, and the other end of the pulling rope is fixed to the back of the lower clamping plate.

The fabric body is in pressing contact with the top and bottom of the side between the two groups of clamping components with the belt, and the two ends of the belt respectively slide through the upper clamping plate and the lower clamping plate.

[0006] Further, a bidirectional electric push rod is fixed inside the sliding groove. The two extending ends of the bidirectional electric push rod are fixed to the bottom of the vertical frame. Vertical grooves are formed on both sides of the vertical frame, and a moving seat is slidably installed inside the vertical groove. The two ends of the installation shaft are rotatably installed on the moving seat through bearings.

[0007] Further, a connecting shaft is rotatably installed on the outside of the moving seat, and the connecting shaft is fixed to the two ends of the installation shaft. A plurality of jacks are annularly arranged on the surface of the connecting shaft. A plug post is arranged at the bottom of the base corresponding to the connecting shaft, and the plug post is slidably inserted into the jacks.

[0008] Further, side frames are arranged on both sides of the base, and two sliders are symmetrically and slidably connected inside the side frames. The bottom of the plug post is fixed to the slider. A first electric push rod is fixed to the bottom of both ends of the base corresponding to the side frames, and the extending end of the first electric push rod is fixed to the side frame.

[0009] Further, the clamping component further includes a moving frame. A moving frame is fixed to one side of the upper clamping plate and the lower clamping plate. Limit blocks are slidably installed on both sides of the moving frame corresponding to the fabric body. The limit frame is in pressing contact with the side of the fabric body. A vertical plate is fixed to the back of the limit plate of the lower clamping plate, and the limit block of the upper clamping plate is slidably sleeved on the surface of the vertical plate.

[0010] Further, the driving assembly further includes a sliding rod. A sliding rod is fixed to the vertical frame corresponding to the bottom of the lower clamping plate, and the bottom of the lower clamping plate is slidably sleeved on the sliding rod. The back of the lower clamping plate is fixedly connected to the pulling rope. Two guiding blocks are fixed to the surface of the vertical frame corresponding to the path of the pulling rope, and the pulling rope slidably passes through the guiding blocks.

[0011] Further, second gears are fixed to the outer ends of both of the winding shafts. The two second gears are meshed and connected. A driving motor is fixed to one side of the base where the second gears are located, and a first gear is fixed to the output end of the driving motor. The first gear is meshed and connected with the second gear.

[0012] Further, the side stretching assembly further includes a connecting frame. A connecting frame is arranged on the top of the belt, and receiving grooves are formed in both sides of the bottom of the connecting frame. Connecting blocks are slidably installed inside the receiving grooves. Both ends of the belt are fixedly connected to the connecting blocks, and springs are fixed between the inner walls of the receiving grooves and the connecting blocks.

[0013] Further, limiting plates are fixed to the sides of the limiting blocks of the upper clamping plate and the lower clamping plate facing the belt, and the belt slidably passes through the limiting plates.

[0014] Further, a bidirectional telescopic plate is arranged at the bottom of the connecting frame, and both ends of the bidirectional telescopic plate are slidably connected to the vertical surfaces of the limiting plates. A plurality of second electric push rods are fixedly arranged at equal intervals on the surface of the connecting frame, and the extending ends of the second electric push rods are fixedly connected to the bidirectional telescopic plate.

[0015] Advantages of the present invention:

[0016] 1. In the present invention, since the two extending ends of the bidirectional telescopic plate are slidably sleeved on the vertical surfaces of the limiting plates, when adjusting the distance between the two clamping assemblies, the length of the bidirectional telescopic plate is automatically adjusted to maintain the connection with the limiting plates. At the same time, because the belt passes through the two limiting plates, the top of the belt drives the connecting block to slide along the receiving groove, and the length of the belt is automatically adjusted for fabric bodies of different lengths.

[0017] 2. After the horizontal stretching test is completed or before the horizontal stretching test in the present invention, the second electric push rod drives the bidirectional telescopic plate to descend, so that the bidirectional telescopic plate presses on the surface of the belt. The positions of the bidirectional telescopic plate and the limiting plate are fixed by bolts, so that the bidirectional telescopic plate cooperates with the belt to clamp both sides of the fabric body. Driven by the bidirectional screw inside the lower clamping plate, the belt and the bidirectional telescopic plate can be driven to move by the limiting block to perform stretching detection on both sides of the fabric body.

[0018] 3. According to the present invention, the upper clamping plate can be removed before installing the fabric body. After the fabric body is placed on the upper end of the lower clamping plate, the two ends of the upper clamping plate are fixed to the lower clamping plate by locking bolts, and the surface of the fabric body is clamped and fixed. The limit frame between the upper clamping plate and the lower clamping plate is attached to both sides of the fabric body, and after the upper clamping plate and the lower clamping plate are locked, the two sides of the fabric body are clamped and limited to prevent the fabric body from tilting.

[0019] 4. The present invention drives the two vertical frames to slide along the slide groove through a bidirectional electric push rod, adjusts the distance between the two vertical frames, and the clamping components move synchronously. The pull rope of the driving component is also unwound synchronously, thereby changing the distance between the two clamping components and further changing the measured length of the fabric body.

[0020] 5. Before measurement, the present invention moves the slider along the side frame to the bottom of the connecting shaft. After the column is inserted into the socket, the first electric push rod drives the side frame to move upward, the column supports the connecting shaft and moves upward, the slide seat slides along the vertical groove, and the two ends of the installation shaft and the fabric body also move upward. During this process, the clamping assembly does not clamp and fix the surface of the fabric body, and stops when the vertical movement of the installation shaft is blocked. The clamping assembly clamps and fixes the fabric body. At this time, the fabric body is adjusted to a taut and flat state by moving the installation shaft upward to avoid bending and wrinkles that affect the detection accuracy.

[0021] 6. Compared with the prior art, the present invention installs both ends of the fabric on a vertical frame, and the detection length can be freely adjusted. The clamping assembly clamps and fixes the two ends of the fabric detection length, and through the movement of the mounting shaft, the fabric at the detection position is kept taut and flat. The clamping assembly cooperates with the driving assembly and the side panel stretching assembly to respectively detect the tensile properties of the fabric in the transverse and longitudinal directions, which makes the detection more convenient and more accurate.

Two vertical frames 2 are symmetrically arranged on the top of the base 1, and two sliding grooves 11 are formed on the surface of the base 1. The bottom of the vertical frame 2 slides along the sliding groove 11. An installation shaft 23 is installed inside the vertical frame 2. A fabric body 3 is installed between the two installation shafts 23. A clamping assembly 4 is arranged on one side of the vertical frame 2. The clamping assembly 4 includes a lower clamping plate 41 and an upper clamping plate 42. The upper clamping plate 42 and the lower clamping plate 41 are in extrusion contact with the top and bottom of the fabric body 3. Locking bolts 44 are rotatably installed at both ends of the upper clamping plate 42, and the upper clamping plate 42 and the lower clamping plate 41 are locked and connected through the locking bolts 44. A driving assembly 5 is arranged on the middle surface of the base 1. The driving assembly 5 includes two winding rods 57. Two winding rods 57 are symmetrically and rotatably installed on the middle surface of the base 1 through bearing seats, and winding shafts 58 are fixed at both ends of the winding rod 57. A pulling rope 51 is wound on the winding shaft 58, and the other end of the pulling rope 51 is fixedly connected to the back of the lower clamping plate 41. A side stretching assembly 6 is arranged between the two groups of clamping assemblies 4. The side stretching assembly 6 includes a belt 61. The fabric body 3 is in extrusion contact with the belt 61 at the top and bottom of the side between the two groups of clamping assemblies 4, and both ends of the belt 61 respectively slide through the upper clamping plate 42 and the lower clamping plate 41. When using the device, both ends of the fabric body 3 are installed on the installation shaft 23. After adjusting the position of the installation shaft 23 to make the fabric body 3 flat, the clamping assembly 4 clamps and fixes both ends of the fabric body 3. The driving assembly 5 drives the clamping assembly 4 to move to perform tensile detection on the surface of the fabric body 3. After or before the transverse tensile detection, the side stretching assembly 6 can be used to detect the tensile property of the side of the fabric body 3.

[0033] In this embodiment, a bidirectional electric push rod 12 is fixed inside the sliding groove 11. The two extending ends of the bidirectional electric push rod 12 are fixedly connected to the bottom of the vertical frame 2. Vertical grooves 21 are formed on both sides of the vertical frame 2, and a moving seat 22 is slidably installed inside the vertical grooves 21. Both ends of the mounting shaft 23 are rotatably installed on the moving seat 22 through bearings. A connecting shaft 24 is rotatably installed on the outside of the moving seat 22, and the connecting shaft 24 is fixedly connected to both ends of the mounting shaft 23. A plurality of jacks 25 are annularly arranged on the surface of the connecting shaft 24. The base 1 is provided with a plug post 16 corresponding to the bottom of the connecting shaft 24, and the plug post 16 is slidably inserted into the jacks 25. Side frames 13 are provided on both sides of the base 1, and two sliders 14 are symmetrically and slidably connected inside the side frames 13. The bottom of the plug post 16 is fixed to the slider 14. The base 1 is fixedly provided with a first electric push rod 15 corresponding to the bottom ends of both ends of the side frame 13, and the extending end of the first electric push rod 15 is fixedly connected to the side frame 13. Both ends of the fabric body 3 are wound around the mounting shaft 23, and the surface to be detected passes through the two clamping assemblies 4. The bidirectional electric push rod 12 drives the two vertical frames 2 to slide along the sliding groove 11, adjusts the distance between the two vertical frames 2, the clamping assemblies 4 move synchronously, and the pull rope 51 of the driving assembly 5 is also unwound synchronously, changing the distance between the two clamping assemblies 4, and thus the measured length of the fabric body 3 can be changed. Before measurement, the slider 14 is moved along the side frame 13 to the bottom of the connecting shaft 24. After the plug post 16 is inserted into the jack 25, the first electric push rod 15 drives the side frame 13 to move upward, the plug post 16 pushes the connecting shaft 24 to move upward, the sliding seat slides along the vertical groove 21, and both ends of the mounting shaft 23 and the fabric body 3 will also move upward. During this process, the clamping assemblies 4 do not clamp and fix the surface of the fabric body 3. Stop when the vertical movement of the mounting shaft 23 is blocked, and the clamping assemblies 4 clamp and fix the fabric body 3. At this time, by moving the mounting shaft 23 upward, the fabric body 3 is adjusted to a tight and flat state, avoiding bending and wrinkles that affect the detection accuracy.

[0034] In this embodiment, the clamping assembly 4 further includes a moving frame 43. One side of the upper clamping plate 42 and the lower clamping plate 41 is fixedly provided with the moving frame 43, and limit blocks 45 are slidably installed inside the moving frame 43 corresponding to both sides of the fabric body 3. The limit frame is in pressing contact with the side of the fabric body 3. A vertical plate 46 is fixed to the back of the limit plate 48 of the lower clamping plate 41, and the limit blocks 45 of the upper clamping plate 42 are slidably sleeved on the surface of the vertical plate 46. Before installing the fabric body 3, the upper clamping plate 42 can be removed. After the fabric body 3 is placed on the upper end of the lower clamping plate 41, both ends of the upper clamping plate 42 are fixed to the lower clamping plate 41 through locking bolts 44, and the surface of the fabric body 3 is clamped and fixed. The limit frames between the upper clamping plate 42 and the lower clamping plate 41 are attached to both sides of the fabric body 3, and after the upper clamping plate 42 and the lower clamping plate 41 are locked, both sides of the fabric body 3 are clamped and limited to prevent the fabric body 3 from tilting.

[0035] In this embodiment, the driving assembly 5 further includes a sliding rod 53. The vertical frame 2 is fixed with a sliding rod 53 corresponding to the bottom of the lower clamping plate 41, and the bottom of the lower clamping plate 41 is slidably sleeved on the sliding rod 53. The back surface of the lower clamping plate 41 is fixedly connected to the pulling rope 51. Two guiding blocks 52 are fixed on the surface of the vertical frame 2 corresponding to the path of the pulling rope 51, and the pulling rope 51 slidably passes through the guiding blocks 52. Second gears 56 are fixed to the outer ends of both the winding shafts 58. The two second gears 56 are meshed and connected. A driving motor 54 is fixed on one side of the base 1 where the second gear 56 is located, and a first gear 55 is fixed to the output end of the driving motor 54. The first gear 55 is meshed with the second gear 56. The driving motor 54 drives the first gear 55 to rotate. When the first gear 55 is meshed with one of the second gears 56, the two second gears 56 mesh and rotate with each other, so that the two winding rods 57 and the winding shafts 58 rotate synchronously and in opposite directions, driving the pulling rope 51 to bypass the guiding blocks 52 to pull the clamping assembly 4 to move towards both ends of the base 1, and perform a stretching test on the fabric body 3. During the movement, the lower clamping plate 41 slides along the sliding rod 53 to maintain the movement in the horizontal direction.

[0036] In this embodiment, the side stretching assembly 6 further includes a connection frame 62. The connection frame 62 is arranged at the top of the belt 61. Two sides at the bottom of the connection frame 62 are provided with storage grooves 65. A connection block 66 is slidably installed inside the storage groove 65. Both ends of the belt 61 are fixed to the connection block 66. A spring 67 is fixed between the inner wall of the storage groove 65 and the connection block 66. A limiting plate 48 is fixed to the side of the limiting block 45 of the upper clamping plate 42 and the lower clamping plate 41 facing the belt 61. The belt 61 slidably passes through the limiting plate 48. A bidirectional telescopic plate 64 is arranged at the bottom of the connection frame 62. Both ends of the bidirectional telescopic plate 64 are slidably connected to the vertical surface of the limiting plate 48. A plurality of second electric push rods 63 are equidistantly fixed on the surface of the connection frame 62. The extending end of the second electric push rod 63 is fixed to the bidirectional telescopic plate 64. Since the two extending ends of the bidirectional telescopic plate 64 are slidably sleeved on the vertical surface of the limiting plate 48, when adjusting the distance between the two clamping assemblies 4, the length of the bidirectional telescopic plate 64 is automatically adjusted to maintain the connection with the limiting plate 48. At the same time, because the belt 61 passes through the two limiting plates 48, the top of the belt 61 drives the connection block 66 to slide along the storage groove 65, and the length of the belt 61 is automatically adjusted. For fabric bodies 3 of different lengths, the belt 61 covers the top and bottom of its side. After the transverse stretching test is completed or before the transverse stretching test, the second electric push rod 63 drives the bidirectional telescopic plate 64 to descend, so that the bidirectional telescopic plate 64 presses on the surface of the belt 61. The positions of the bidirectional telescopic plate 64 and the limiting plate 48 are fixed by bolts, so that the bidirectional telescopic plate 64 cooperates with the belt 61 to clamp both sides of the fabric body 3. Driven by the bidirectional screw rod 47 inside the lower clamping plate 41, the belt 61 and the bidirectional telescopic plate 64 can be driven to move by the limiting block 45 to perform stretching detection on both sides of the fabric body 3.

[0037] When using the device, both ends of the fabric body 3 are wound around the mounting shaft 23, and the surface to be detected passes through the two clamping assemblies 4. The two vertical frames 2 are driven by the bidirectional electric push rod 12 to slide along the sliding groove 11 to adjust the distance between the two vertical frames 2. The clamping assemblies 4 move synchronously, and the pulling rope 51 of the driving assembly 5 is also unwound synchronously to change the distance between the two clamping assemblies 4, thereby changing the length of the fabric body 3 to be measured. Before measurement, the slider 14 is moved along the side frame 13 to the bottom of the connecting shaft 24. After the insertion post 16 is inserted into the insertion hole 25, the first electric push rod 15 drives the side frame 13 to move upward, and the insertion post 16 pushes the connecting shaft 24 to move upward. The sliding seat slides along the vertical groove 21, and both ends of the mounting shaft 23 and the fabric body 3 will also move upward. During this process, the clamping assembly 4 does not clamp and fix the surface of the fabric body 3 and stops when the vertical movement of the mounting shaft 23 is blocked. The clamping assembly 4 clamps and fixes the fabric body 3. At this time, by moving the mounting shaft 23 upward, the fabric body 3 is adjusted to a taut and flat state to avoid bending and wrinkles affecting the detection accuracy. Before installing the fabric body 3, the upper clamping plate 42 can be removed. After the fabric body 3 is placed on the upper end of the lower clamping plate 41, both ends of the upper clamping plate 42 are fixed to the lower clamping plate 41 through the locking bolts 44 and clamp and fix the surface of the fabric body 3. The limiting frames between the upper clamping plate 42 and the lower clamping plate 41 are attached to both sides of the fabric body 3, and after the upper clamping plate 42 and the lower clamping plate 41 are locked, both sides of the fabric body 3 are clamped and limited to prevent the fabric body 3 from tilting. Since the two extended ends of the bidirectional telescopic plate 64 are slidably sleeved on the vertical surfaces of the limiting plates 48, when adjusting the distance between the two clamping assemblies 4, the length of the bidirectional telescopic plate 64 is automatically adjusted to maintain the connection with the limiting plates 48. At the same time, because the belt 61 passes through the two limiting plates 48, the top of the belt 61 drives the connecting block 66 to slide along the storage groove 65, and the length of the belt 61 is automatically adjusted. For fabric bodies 3 of different lengths, the belt 61 covers the top and bottom of its side. After the transverse tensile test is completed or before the transverse tensile test, the second electric push rod 63 drives the bidirectional telescopic plate 64 to descend so that the bidirectional telescopic plate 64 presses on the surface of the belt 61, and the positions of the bidirectional telescopic plate 64 and the limiting plate 48 are fixed by bolts, so that the bidirectional telescopic plate 64 cooperates with the belt 61 to clamp both sides of the fabric body 3. Driven by the bidirectional screw rod 47 inside the lower clamping plate 41, the belt 61 and the bidirectional telescopic plate 64 can be driven to move by the limiting block 45 to perform tensile detection on both sides of the fabric body 3. The driving motor 54 drives the first gear 55 to rotate. When the first gear 55 meshes with the second gear 56 on one side, the two second gears 56 mesh and rotate with each other, so that the two winding rods 57 and the winding shaft 58 rotate synchronously and in opposite directions, driving the pulling rope 51 to bypass the guiding block 52 to pull the clamping assembly 4 to move towards both ends of the base 1 to perform tensile detection on the fabric body 3. The lower clamping plate 41 slides along the sliding rod 53 during the movement to maintain the horizontal movement.
