[0004] However, the current elastic testing device has the following problems: the elastic testing device is not suitable for elastic testing of fabrics of different lengths, and thus cannot comprehensively evaluate fabrics of different types or specifications, which limits the application scope of the equipment. Therefore, we propose an elastic testing device for fabrics. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fabric elasticity testing device, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a fabric elasticity testing device, including a device body, a test device body for testing the elasticity of the fabric is arranged on the outside of the device body, an adaptation device is arranged on the inside of the device body, the adaptation device includes a bidirectional screw, two T-shaped plates, two positioning rods, two pressure plates, and two threaded rods. The bidirectional screw is rotatably installed inside the device body, and the bidirectional screw is driven by a motor. The two T-shaped plates are threadedly connected to the two sides of the outside of the bidirectional screw, and the T-shaped plate is slidably installed on the bottom of the inner wall of the device body. The two positioning rods are respectively fixed to the top of one side of the two T-shaped plates, and the two threaded rods are respectively rotatably installed on the other side of the two T-shaped plates. On the top of the side, one end of the two pressing plates is slidably installed on the outside of the two positioning rods, and the other ends of the two pressing plates are threadedly connected to the outside of the two threaded rods. The fabric is placed between the tops of the two T-shaped plates, and the threaded rods on one side are rotated, and the threaded rods on one side drive the pressing plate on one side to move downward along the outside of the positioning rods, so that the pressing plate and the T-shaped plate on one side clamp one side of the fabric. Then, the bidirectional screw is driven by a motor to rotate, and the bidirectional screw drives the two T-shaped plates to move along the bottom of the inner wall of the device body toward both sides of the device body until the distance between the two T-shaped plates is equal to the length of the fabric, and the threaded rods on the other side are rotated, and the threaded rods on the other side drive the pressing plate on the other side to clamp the other side of the fabric.

[0007] According to the above technical solution, the adaptation device also includes two serrated blocks and two serrated grooves. The two serrated blocks are respectively embedded in the bottom of one side of the two pressing plates away from each other, and the two serrated grooves are respectively opened on the top of the two T-shaped plates, and the serrated grooves are located directly below the serrated blocks. At the same time, when the pressing plate moves downward, the serrated block will be driven to move downward, and the serrated block will press the fabric in the serrated groove. The serrated blocks in the serrated block can effectively clamp the fabric and firmly fix it in the serrated groove.

[0008] According to the above technical solution, the adaptation device also includes four hinged rods, four slide slot plates, four limit rods, and two fixed plates. The two fixed plates are respectively fixed on the side of the two T-shaped plates away from each other, one end of the four hinged rods is respectively hinged on the side of the two pressure plates away from each other, the four slide slot plates are respectively hinged on the other end of the four hinged rods, the four limit rods are respectively vertically penetrated and slidably installed on the side of the two pressure plates away from each other, and the bottoms of the four limit rods are respectively slidably connected to the tops of the four slide slot plates, and the limit rods are respectively connected to the pressure plates. A spring is provided between the outer walls of the plates, and during the downward movement of the pressure plate, the hinged rod will first be driven to push the slide plate downward, and the slide plate will drive the limit rod to move downward. The limit rod here will limit the vertical movement trajectory of the slide plate, and since the bottom of the limit rod and the slide plate are slidably connected, the limit rod will not limit the lateral movement trajectory of the slide plate. When the hinged rod pushes the slide plate to contact the fabric that falls on the fixed plate, the hinged rod continues to move downward, and the hinged rod pushes the slide plate to move along the top surface of the fixed plate in the direction away from the T-shaped plate.

[0009] According to the above technical scheme, the main body of the test equipment includes a U-shaped frame, a hydraulic cylinder, a pressure sensor, a sliding column, and a threaded rod. The sliding column is fixed on one side of the top of the device body, and the threaded rod is rotatably installed on the other side of the top of the device body. One end of the U-shaped frame is slidably installed on the outside of the sliding column, and the other end of the U-shaped frame is threadedly connected to the outside of the threaded rod. The hydraulic cylinder is fixed on the top of the U-shaped frame, and the pressure sensor is fixed on the bottom of the telescopic end of the hydraulic cylinder. By rotating the threaded rod, the threaded rod drives the U-shaped frame to move along the outside of the sliding column. The position of the U-shaped frame is adjusted according to the position on the surface of the fabric where the elasticity test needs to be performed, and then the hydraulic cylinder is started. The telescopic end of the hydraulic cylinder drives the pressure sensor to contact, and the pressure sensor pushes the fabric to deform, thereby achieving the purpose of elastic testing of the fabric.

[0010] According to the above technical scheme, a smoothing device is provided on the side where the two T-shaped plates are close to each other, and the smoothing device includes four elastic telescopic rods, two pressure rollers 1 and two pressure rollers 2. The fixed ends of the four elastic telescopic rods are respectively fixed on the side where the two pressure plates are close to each other, and two of the four elastic telescopic rods form a group. The two pressure rollers 1 are respectively rotatably installed between the bottoms of the telescopic ends of two adjacent elastic telescopic rods, and the two pressure rollers 2 are respectively rotatably installed on the side where the two T-shaped plates are close to each other through brackets. The outer wall of the pressure roller 2 is in contact with the outer wall of the pressure roller 1, and the outer surfaces of the pressure roller 2 and the pressure roller 1 are both rough surfaces. When the fabric is placed between the tops of the two T-shaped plates, and the fabric is passed through the pressure rollers 1 and 2, under the elastic force of the elastic telescopic rods, the telescopic ends of the elastic telescopic rods drive the pressure rollers 2 to press the fabric on the pressure roller 1.

[0011] According to the above technical scheme, the smoothing device also includes two Z-shaped rods, a tooth plate, two gears, and two elastic telescopic columns. The two elastic telescopic columns are respectively fixed on one side of the top of the device body, and the tooth plate is fixed between the outer walls of the telescopic ends of the two elastic telescopic columns. One end of the two Z-shaped rods is respectively fixed on the outer wall of the telescopic ends of the two elastic telescopic rods on one side, and the other ends of the two Z-shaped rods are slidably installed on the outer wall of the tooth plate. The two gears are respectively fixed on the rotating shafts of the two pressure rollers one, and the gears are meshed with the tooth plate. At the same time, when the pressure roller one moves, it will drive the gear to move with it, and the tooth plate will drive the gear to rotate, and the gear will drive the pressure roller two to rotate, so that the pressure roller two drives the fabric to roll in the direction of the pressure plate.

[0012] According to the above technical solution, a simulation device is provided on the outside of one side of the two T-shaped plates, and the simulation device includes a water tank, a water injection pipe, an L-shaped pipe, a straight pipe, a plurality of nozzles, a pressing piece, and a triangular block rod. The water tank is fixed on the outer wall of the T-shaped plate, the water injection pipe is fixed on one side of the top of the water tank, the L-shaped pipe is fixed on the top of the water tank, the straight pipe is fixed on the end of the L-shaped pipe away from the water tank, and a plurality of nozzles are evenly and equidistantly fixed on the bottom of the straight pipe. The pressing piece is fixed on the outer wall of the rear side of the water tank, and the triangular block rod is fixed on the inner wall of the device body. The pressing piece is used to control the water in the water tank to pass through the L-shaped pipe and the straight pipe. The pressing part is output to the nozzle for spraying. A plurality of triangular blocks are fixed on one side of the triangular block rod close to the water tank. The pressing end of the pressing piece is arranged in a semi-arc shape. The triangular block inclined surface of the triangular block rod is located on the semi-arc movement trajectory of the pressing end of the pressing piece. The T-shaped plate drives the pressing piece to move with it through the water tank. When the pressing end of the pressing piece moves in a semi-arc shape to the position of the triangular block inclined surface of the triangular block rod, the triangular block inclined surface of the triangular block rod pushes the pressing end of the pressing piece in a semi-arc shape to squeeze the pressing end of the pressing piece. The pressing piece is used to control the water in the water tank to be transmitted to the nozzle through the L-shaped pipe and the straight pipe for spraying. The water sprayed from the nozzle will sprinkle on the surface of the fabric and wet the fabric.

[0013] The present invention provides a fabric elasticity testing device, which has the following beneficial effects:

[0014] (1) The present invention adopts the setting of an adaptive device so that the threaded rod 2, the pressure plate, the positioning rod, the pressure plate, and the T-shaped plate cooperate with each other, so that the elasticity testing device can adapt to the elasticity testing of fabrics of different lengths, thereby ensuring that the elasticity testing device can comprehensively evaluate fabrics of different types or specifications, thereby expanding the application scope of the elasticity testing device; at the same time, the pressure plate and the serrated block plate cooperate to press the fabric into the serrated groove, and the serrated blocks in the serrated block plate can effectively clamp the fabric and firmly fix it in the serrated groove to prevent the fabric from sliding during the elasticity testing process, thereby improving the accuracy of the fabric elasticity testing; at the same time, the pressure plate, the hinged rod, the slide plate, and the limit rod cooperate to drive the slide plate to pull the fabric to both sides. Pulling the fabric to both sides by the slide plate can effectively reduce the wrinkles on the fabric, making it smoother, thereby facilitating the elasticity testing of the fabric.

[0015] (2) The present invention sets a smoothing device so that the T-shaped plate, pressure roller one, pressure roller two, and elastic telescopic rod cooperate to drive pressure roller two to press the fabric on pressure roller one, thereby avoiding the problem that the fabric is easy to slip off the T-shaped plate on the other side during the movement of the pressure plate on the other side. At the same time, the T-shaped plate on the other side will drive pressure roller two and pressure roller one to smooth the fabric during the movement, thereby ensuring that the fabric is in a flat state after straightening; at the same time, pressure roller one, gears, toothed plates, and pressure roller two cooperate so that pressure roller two drives the fabric to roll in the direction of the pressure plate. The rotation of pressure roller two can effectively tighten the fabric, help eliminate wrinkles, and make the surface of the fabric smoother.

[0016] (3) The present invention uses the setting of a simulation device so that the T-shaped plate, the water tank, the pressing piece, and the triangular block rod cooperate to squeeze the pressing end of the pressing piece. The pressing piece is used to control the water in the water tank to be transmitted through the L-shaped tube and the straight tube to the nozzle for spraying. The water sprayed from the nozzle will sprinkle on the surface of the fabric and wet the fabric, so that the elasticity testing device can perform elasticity testing on the fabric when the fabric is wet.

[0028] See also Figure 1 - Figure 8One embodiment of the present invention is: a fabric elasticity testing device, comprising a device body 1, a test device body 2 for testing the elasticity of the fabric is arranged outside the device body 1, an adaption device 3 is arranged inside the device body 1, the adaption device 3 comprises a bidirectional screw 31, two T-shaped plates 32, two positioning rods 33, two pressing plates 34, and two threaded rods 35, the bidirectional screw 31 is rotatably installed inside the device body 1, and the bidirectional screw 31 is driven by a motor, the two T-shaped plates 32 are threadedly connected to the two sides of the outside of the bidirectional screw 31, and the T-shaped plates 32 are slidably installed inside the device body 1 At the bottom of the wall, two positioning rods 33 are respectively fixed on the top of one side of the two T-shaped plates 32, and two threaded rods 35 are respectively rotatably installed on the top of the other side of the two T-shaped plates 32. One end of the two pressing plates 34 is respectively slidably installed on the outside of the two positioning rods 33, and the other ends of the two pressing plates 34 are respectively threadedly connected to the outside of the two threaded rods 35. Through the arrangement of the above structure, the elasticity testing device can adapt to the elasticity testing of fabrics of different lengths, thereby ensuring that the elasticity testing device can comprehensively evaluate fabrics of different types or specifications, expanding the application range of the elasticity testing device.

[0029] The adaptation device 3 also includes two serrated blocks 36 and two serrated grooves 37. The two serrated blocks 36 are respectively embedded in the bottom of the side of the two pressing plates 34 away from each other. The two serrated grooves 37 are respectively opened on the top of the two T-shaped plates 32, and the serrated grooves 37 are located directly below the serrated blocks 36. Through the arrangement of the above structure, the serrated blocks in the serrated blocks 36 can effectively clamp the fabric and firmly fix it in the serrated grooves 37, thereby preventing the fabric from sliding during the elasticity test, thereby improving the accuracy of the fabric elasticity test.

[0030] The adaptation device 3 also includes four hinged rods 38, four slide plates 39, four limit rods 310, and two fixed plates 311. The two fixed plates 311 are respectively fixed on the side of the two T-shaped plates 32 away from each other. One end of the four hinged rods 38 is respectively hinged on the side of the two pressure plates 34 away from each other.

The four limit rods 310 are respectively vertically penetrated and slidably installed on the side of the two pressure plates 34 away from each other, and the bottoms of the four limit rods 310 are respectively slidably connected to the tops of the four slide plates 39. A spring is provided between the limit rod 310 and the outer wall of the pressure plate 34. Through the arrangement of the above structure, the slide plate 39 pulls the fabric to both sides. Pulling the fabric to both sides by the slide plate 39 can effectively reduce the wrinkles on the fabric and make it smoother, which is beneficial to the elasticity test of the fabric.

[0031] The test equipment body 2 includes a U-shaped frame 21, a hydraulic cylinder 22, a pressure sensor 23, a sliding column 24, and a threaded rod 25. The sliding column 24 is fixed on one side of the top of the device body 1, and the threaded rod 25 is rotatably installed on the other side of the top of the device body 1. One end of the U-shaped frame 21 is slidably installed on the outside of the sliding column 24, and the other end of the U-shaped frame 21 is threadedly connected to the outside of the threaded rod 25. The hydraulic cylinder 22 is fixed on the top of the U-shaped frame 21, and the pressure sensor 23 is fixed on the bottom of the telescopic end of the hydraulic cylinder 22. Through the arrangement of the above structure, the telescopic end of the hydraulic cylinder 22 drives the pressure sensor 23 to contact, and the pressure sensor 23 pushes the fabric to deform, thereby achieving the purpose of elastic testing of the fabric. The staff can determine the result of the fabric elasticity test by observing the value of the pressure sensor 23.

[0032] A smoothing device 4 is provided on the side where the two T-shaped plates 32 are close to each other. The smoothing device 4 includes four elastic telescopic rods 41, two pressure rollers 1 42, and two pressure rollers 2 43. The fixed ends of the four elastic telescopic rods 41 are respectively fixed on the side where the two pressure plates 34 are close to each other. Two of the four elastic telescopic rods 41 form a group. The two pressure rollers 1 42 are respectively rotatably installed between the bottoms of the telescopic ends of the two adjacent elastic telescopic rods 41. The two pressure rollers 2 43 are respectively rotatably installed on the side where the two T-shaped plates 32 are close to each other through brackets. The outer wall of the second pressing roller 43 is in contact with the outer wall of the first pressing roller 42, and the outer surfaces of the second pressing roller 43 and the first pressing roller 42 are both rough surfaces. Through the arrangement of the above structure, the telescopic end of the elastic telescopic rod 41 drives the second pressing roller 43 to press the fabric on the first pressing roller 42, thereby avoiding the problem that the fabric is easily slipped off the T-shaped plate 32 on the other side during the movement of the pressure plate 34 on the other side. At the same time, the movement of the T-shaped plate 32 on the other side will drive the second pressing roller 43 and the first pressing roller 42 to smooth the fabric, thereby ensuring that the fabric is in a flat state after being straightened.

[0033] The smoothing device 4 also includes two Z-shaped rods 44, a tooth plate 45, two gears 46, and two elastic telescopic columns 47. The two elastic telescopic columns 47 are respectively fixed on one side of the top of the device body 1, and the tooth plate 45 is fixed between the outer walls of the telescopic ends of the two elastic telescopic columns 47. One end of the two Z-shaped rods 44 is respectively fixed on the outer wall of the telescopic ends of the two elastic telescopic rods 41 on one side, and the other ends of the two Z-shaped rods 44 are slidably installed on the outer wall of the tooth plate 45. The two gears 46 are respectively fixed on the rotating shafts of the two pressure rollers 42, and the gears 46 are meshed with the tooth plate 45. Through the arrangement of the above structure, the pressure roller 43 drives the fabric to roll in the direction of the pressure plate 34. The rotation of the pressure roller 43 can effectively tighten the fabric, help eliminate wrinkles, and make the fabric surface smoother.

[0034] When in use, the fabric is placed between the tops of the two T-shaped plates 32, and the threaded rod 35 on one side is rotated, so that the threaded rod 35 on one side drives the pressure plate 34 on one side to move downward along the outside of the positioning rod 33, so that the pressure plate 34 on one side and the T-shaped plate 32 clamp one side of the fabric. Then, the bidirectional screw 31 is driven by the motor to rotate, and the bidirectional screw 31 drives the two T-shaped plates 32 to move along the bottom of the inner wall of the device body 1 toward the two sides of the device body 1 until the distance between the two T-shaped plates 32 is equal to the length of the fabric, and the threaded rod 35 on the other side is rotated, so that the threaded rod 35 on the other side drives the pressure plate 34 on the other side to clamp the fabric The other side of the elastic test device is clamped, so that the elastic test device can adapt to the elastic test of fabrics of different lengths, thereby ensuring that the elastic test device can comprehensively evaluate fabrics of different types or specifications, expanding the application range of the elastic test device; at the same time, when the pressing plate 34 moves downward, it will drive the sawtooth block plate 36 to move downward, and the sawtooth block plate 36 will press the fabric in the sawtooth groove 37. The sawtooth blocks in the sawtooth block plate 36 can effectively clamp the fabric and firmly fix it in the sawtooth groove 37 to prevent the fabric from sliding during the elastic test, thereby improving the accuracy of the fabric elasticity test; at the same time, when the pressing plate 34 moves downward, During the process, the hinge rod 38 will first drive the sliding groove plate 39 to move downward, and the sliding groove plate 39 will drive the limiting rod 310 to move downward. Here, the limiting rod 310 will limit the vertical movement trajectory of the sliding groove plate 39, and because the bottom of the limiting rod 310 and the sliding groove plate 39 are slidably connected, the limiting rod 310 will not limit the lateral movement trajectory of the sliding groove plate 39. When the hinge rod 38 pushes the sliding groove plate 39 to contact the fabric fallen on the fixed plate 311, the hinge rod 38 continues to move downward, and the hinge rod 38 pushes the sliding groove plate 39 to move along the top surface of the fixed plate 311 in the direction away from the T-shaped plate 32, so that the sliding groove plate 39 moves the fabric to Pulling on both sides, pulling the fabric to both sides through the slide plate 39 can effectively reduce wrinkles on the fabric and make it smoother, which is beneficial to the elasticity test of the fabric. Rotate the threaded rod 25, and the threaded rod 25 drives the U-shaped frame 21 to move along the outside of the slide column 24. The position of the U-shaped frame 21 is adjusted according to the position on the fabric surface where the elasticity test needs to be performed. Then start the hydraulic cylinder 22. The telescopic end of the hydraulic cylinder 22 drives the pressure sensor 23 to contact, and the pressure sensor 23 pushes the fabric to deform, thereby achieving the purpose of elasticity testing the fabric. The staff can determine the result of the fabric elasticity test by observing the value of the pressure sensor 23.

[0035] When the fabric is placed between the tops of the two T-shaped plates 32 and passed through the pressing roller 1 42 and the pressing roller 2 43, under the elastic force of the elastic telescopic rod 41, the telescopic end of the elastic telescopic rod 41 drives the pressing roller 2 43 to press the fabric on the pressing roller 1 42, thereby avoiding the problem that the fabric is easily slipped off the T-shaped plate 32 on the other side during the movement of the pressing plate 34 on the other side. At the same time, the movement of the T-shaped plate 32 on the other side will drive the pressing roller 2 43 and the pressing roller 1 42 to smooth the fabric, thereby ensuring that the fabric is in a flat state after being straightened; at the same time, when the pressing roller 1 42 moves, it will drive the gear 46 to move with it, and the tooth plate 45 will drive the gear 46 to rotate The gear 46 drives the second pressure roller 43 to rotate, so that the second pressure roller 43 drives the fabric to roll in the direction of the pressure plate 34. The rotation of the second pressure roller 43 can effectively tighten the fabric, help eliminate wrinkles, and make the surface of the fabric smoother. When the telescopic end of the elastic telescopic rod 41 here moves upward, the telescopic end of the elastic telescopic rod 41 will drive the tooth plate 45 to move upward through the Z-shaped rod 44, and the tooth plate 45 drives the telescopic end of the elastic telescopic column 47 to stretch upward, so that the tooth plate 45 will not interfere with the upward displacement trajectory of the telescopic end of the elastic telescopic rod 41 through the gear 46, so that fabrics of different thicknesses can be placed between the second pressure roller 43 and the first pressure roller 42.

[0036] See also Fig. 9 On the basis of the above embodiment, in another embodiment of the present invention, a simulation device 5 is provided on the outside of one side of the two T-shaped plates 32, and the simulation device 5 includes a water tank 51, a water injection pipe 52, an L-shaped pipe 53, a straight pipe 54, a plurality of nozzles 55, a pressing piece 56, and a triangular block rod 57. The water tank 51 is fixed to the outer wall of the T-shaped plate 32, the water injection pipe 52 is fixed to one side of the top of the water tank 51, the L-shaped pipe 53 is fixed to the top of the water tank 51, the straight pipe 54 is fixed to the end of the L-shaped pipe 53 away from the water tank 51, a plurality of nozzles 55 are evenly and equidistantly fixed to the bottom of the straight pipe 54, the pressing piece 56 is fixed to the outer wall of the rear side of the water tank 51, and the triangular block rod 57 is fixed to the main body of the device. At the inner wall of the body 1, the pressing piece 56 is used to control the water in the water tank 51 to be transmitted to the nozzle 55 through the L-shaped tube 53 and the straight tube 54 for spraying. A plurality of triangular blocks are fixed to the side of the triangular block rod 57 close to the water tank 51. The pressing end of the pressing piece 56 is arranged in a semi-arc shape, and the triangular block inclined surface of the triangular block rod 57 is located on the semi-arc movement trajectory of the pressing end of the pressing piece 56. Through the arrangement of the above structure, the pressing piece 56 is used to control the water in the water tank 51 to be transmitted to the nozzle 55 through the L-shaped tube 53 and the straight tube 54 for spraying. The water sprayed from the nozzle 55 will sprinkle on the surface of the fabric and wet the fabric, so that the elasticity testing device can perform elasticity test on the fabric when the fabric is wet.

[0037] During use, when it is necessary to simulate the performance of the fabric in the actual use environment, especially the effect of humidity on elasticity and deformation, water is poured into the water tank 51 through the water injection pipe 52. During the movement of the T-shaped plate 32, the T-shaped plate 32 drives the pressing piece 56 to move through the water tank 51. When the pressing end of the pressing piece 56 moves in a semi-arc shape to the triangular block inclined surface position of the triangular block rod 57, the triangular block inclined surface of the triangular block rod 57 pushes the pressing end of the pressing piece 56 in a semi-arc shape to squeeze the pressing end of the pressing piece 56. The pressing piece 56 is used to control the water in the water tank 51 to be transmitted through the L-shaped tube 53 and the straight tube 54 to the nozzle 55 for spraying. The water sprayed from the nozzle 55 will sprinkle on the surface of the fabric and wet the fabric, so that the elasticity testing device can perform elasticity test on the fabric when the fabric is wet.
