A Tensile Testing Device for Colored Nonwoven Fabric

Abstract

This utility model relates to the field of colored nonwoven fabrics, specifically to a colored nonwoven fabric tensile testing device, including a testing platform for testing the tensile strength of colored nonwoven fabrics; and a scale strip disposed on the front side above the testing platform. This utility model's colored nonwoven fabric tensile testing device, through the arrangement of a lead screw, displacement plates, fixed blocks, racks, gears, a second screw, a movable sleeve, a second pressure sensor, and a pressure block, allows the lead screw to rotate when the motor switch on the right side of the testing platform is turned on. The rotation of the lead screw drives the displacement plates on both sides to stretch the colored nonwoven fabric in the middle to both sides. During the movement of the displacement plates, the fixed block and rack above move, and the rack, in turn, drives the inner gear and the inner second screw to rotate. When the second screw rotates, it causes the outer movable sleeve and the lower pressure block to descend, thereby compressing the colored nonwoven fabric from above. Through stretching from both sides and above, the testing effect is improved.

Description

Technical Field

[0001] This utility model relates to the field of colored nonwoven fabrics, and specifically to a tensile testing device for colored nonwoven fabrics. Background Technology

[0002] Colored nonwoven fabric is a type of nonwoven material with rich colors. Its unique manufacturing process cleverly integrates the colors into the material, ensuring long-lasting vibrancy. A colored nonwoven fabric tensile testing device is a specialized instrument used to test the mechanical properties of colored nonwoven fabrics during the tensile process. This device can accurately evaluate key indicators such as tensile strength and elongation at break of nonwoven fabrics, providing important data support for the production and application of nonwoven fabrics.

[0003] A search revealed a utility model for testing the tensile properties of woven fabrics, with publication number CN220912824U. This device includes a base, a fixed arm bolted to the left side of the base, a concave groove bolted to the inner wall of one side of the fixed arm, and a convex pressure block slidably connected to the upper end of the fixed arm. A tensioning fixed arm bolted to the right side of the base, a hydraulic tensioner bolted to the inner wall of one side of the tensioning fixed arm, and a sliding arm in the middle of the base, with a gasket bolted to the outer wall of one side of the sliding arm. The convex pressure block ensures tight compression of the woven fabric during testing, preventing slippage. A scale is included to ensure that the width of the compressed fabric is the same on both sides when compressed.

[0004] Traditional colored nonwoven fabric tensile testing devices only perform tensile tests on both sides. This single test cannot simulate the actual stretching of colored nonwoven fabric, resulting in test results that lack a comprehensive reflection of the material's performance under actual working conditions and reducing test accuracy. The tensile performance testing device for woven fabrics in the aforementioned comparative case is similar to the standard for colored nonwoven fabrics in this case. However, this comparative case also only performs left-right tensile tests and cannot perform up-down tensile tests, thus reducing the accuracy and standard of the test.

[0005] Therefore, it is necessary to invent a colored nonwoven fabric tensile testing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a tensile testing device for colored nonwoven fabrics. By turning on the motor switch on the right side of the test platform, the lead screw is driven to rotate. The rotation of the lead screw drives the displacement plates on both sides to stretch the colored nonwoven fabric in the middle to both sides. During the movement of the displacement plates, the fixed block and rack above move. During the movement of the rack, the inner gear and the inner second screw rotate. When the second screw rotates, it drives the outer movable sleeve and the lower pressure block to descend, thereby squeezing the colored nonwoven fabric from above. Through stretching from both sides and above, the test effect is improved, which solves the problem of the traditional colored nonwoven fabric tensile testing device mentioned in the background art, which only performs a single tensile test on both sides. Such a single test cannot simulate the stretching of colored nonwoven fabric in reality, resulting in the test results lacking a comprehensive reflection of the material's performance under actual working conditions, and also reducing the accuracy of the test.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a colored nonwoven fabric tensile testing device, including a testing platform, for testing the tensile properties of colored nonwoven fabric;

[0008] A scale bar is set on the front side of the test bench for measurement. A signal processing module is fixedly installed on the right side of the test bench. A display is installed on the right side of the test bench. A motor is fixedly installed on the right side of the test bench. A lead screw is fixedly connected to the output end of the motor. Displacement plates are threaded to both sides of the lead screw. A first pressure sensor is fixedly installed on the rear side of the displacement plate. A bracket is fixedly connected to the top of the test bench.

[0009] A clamping mechanism is fixedly installed inside the displacement plate. The clamping mechanism includes a displacement sensor, which is installed on the front side of the displacement plate.

[0010] A fixed block is fixed on one side above the displacement plate. A rack is fixedly connected inside the fixed block. A gear is meshed inside the rack. A second screw is fixedly connected inside the gear. A movable sleeve is threaded onto the outside of the second screw. A second pressure sensor is fixedly installed below the movable sleeve. A pressure block is fixedly connected to the lower end of the second pressure sensor.

[0011] Preferably, the threads of the lead screw are reversed, and the inner sides of the displacement plate are slidably connected to the first slide rod.

[0012] Preferably, the clamping mechanism includes a first screw, a displacement plate is threaded through the upper part of the first screw, a movable plate is rotatably connected to the lower end of the first screw, a telescopic rod is slidably connected to the lower part of the movable plate, a clamping plate is fixedly connected to the lower end of the telescopic rod, a spring is fixedly provided on the outside of the telescopic rod, a fixing plate is fixedly connected to the inside of the displacement plate, and an anti-slip pad is pasted inside the fixing plate.

[0013] Preferably, a protrusion is fixedly connected to the lower part of the movable plate, and a groove is formed on the inner surface of the fixed plate, and the clamping plate is movably engaged with the fixed plate.

[0014] Preferably, the rack is provided in two sets, and the two sets of racks are arranged on one side above the displacement plate, and the racks are meshed with gears.

[0015] Preferably, the second screw is threadedly connected to the movable sleeve, and the upper two sides of the pressure block are fixedly connected to the second slide rod, which is slidably connected to the bracket.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By setting up a lead screw, displacement plate, fixed block, rack, gear, second screw, movable sleeve, second pressure sensor, and pressure block, the colored nonwoven fabric is stretched on both sides during the test, which simultaneously causes the pressure block above to descend, thus simulating the tensile test in a real environment. By turning on the motor switch on the right side of the test platform, the lead screw is driven to rotate. The rotation of the lead screw drives the displacement plates on both sides to stretch the colored nonwoven fabric to both sides. During the movement of the displacement plates, the fixed block and rack above move. During the movement of the rack, the inner gear and the inner second screw rotate. When the second screw rotates, it causes the outer movable sleeve and the pressure block below to descend, thus squeezing the colored nonwoven fabric above. Through the stretching on both sides and above, the test effect is improved.

[0018] 2. The clamping mechanism enhances clamping stability and prevents loosening during stretching. By placing the colored non-woven fabric on both sides between the clamping plate and the fixed plate, multiple sets of telescopic rods above the clamping plate extend and retract within the moving plate. The springs outside the telescopic rods then press against the clamping plate to hold the colored non-woven fabric in place. At the same time, the anti-slip pads enhance the gripping stability. The protrusions below the clamping plate press into the grooves on the outside of the colored non-woven fabric inserted into the fixed plate, further increasing the clamping force and preventing loosening.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-6 The device shown is a tensile testing device for colored nonwoven fabric, including a test platform 1 for tensile testing of colored nonwoven fabric.

[0030] A scale bar 2 is set on the front side above the test bench 1 for measurement. A signal processing module 3 is fixedly set on the right side of the test bench 1. A display 4 is set on the right side of the test bench 1. A motor is fixedly set on the right side of the test bench 1. A lead screw 5 is fixedly connected to the output end of the motor. A displacement plate 6 is threadedly connected to both sides of the lead screw 5. A first pressure sensor 8 is fixedly set on the rear side of the displacement plate 6. A bracket 10 is fixedly connected to the top of the test bench 1.

[0031] The clamping mechanism 9 is fixedly installed inside the displacement plate 6. The clamping mechanism 9 includes a displacement sensor 902, which is installed on the front side of the displacement plate 6.

[0032] A fixed block 11 is fixed on one side above the displacement plate 6. A rack 12 is fixedly connected inside the fixed block 11. A gear 13 is meshed inside the rack 12. A second screw 14 is fixedly connected inside the gear 13. A movable sleeve 15 is threadedly connected to the outside of the second screw 14. A second pressure sensor 16 is fixedly installed below the movable sleeve 15. A pressure block 17 is fixedly connected to the lower end of the second pressure sensor 16. By turning on the motor switch on the right side of the test bench 1, the lead screw 5 is driven to rotate. The rotation of the lead screw 5 drives the colored non-woven fabric between the two sides of the displacement plates 6 to stretch to both sides. During the movement of the displacement plates 6, the fixed block 11 and the rack 12 above move. During the movement of the rack 12, the gear 13 inside and the second screw 14 inside rotate. When the second screw 14 rotates, the movable sleeve 15 outside and the pressure block 17 below descend, thereby squeezing the colored non-woven fabric above. Through stretching from both sides and above, the test effect is improved.

[0033] like Figure 1 As shown, the threads of the lead screw 5 are tapped in opposite directions, and the first slide rod 7 is slidably connected to the inner sides of the displacement plate 6. By turning on the motor switch on the right side of the test bench 1, the lead screw 5 is driven to rotate, while the threads of the lead screw 5 are tapped in opposite directions, thereby causing the two sets of displacement plates 6 to move away from each other and closer together.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the clamping mechanism 9 includes a first screw 901, with a displacement plate 6 threaded through the upper part of the first screw 901. A movable plate 903 is rotatably connected to the lower end of the first screw 901. Telescopic rods 904 are slidably connected to the lower part of the movable plate 903. A clamping plate 905 is fixedly connected to the lower end of the telescopic rods 904. A spring 906 is fixedly installed on the outside of the telescopic rods 904. A fixing plate 908 is fixedly connected to the inside of the displacement plate 6. An anti-slip pad 909 is pasted inside the fixing plate 908. By placing the colored non-woven fabric on both sides between the clamping plate 905 and the fixing plate 908, the multiple sets of telescopic rods 904 above the clamping plate 905 extend and retract within the movable plate 903. The springs 906 on the outside of the telescopic rods 904 then spring back and squeeze the clamping plate 905 to clamp the colored non-woven fabric. At the same time, the anti-slip pad 909 also enhances the anti-slip properties of the clamping.

[0035] like Figure 3 and Figure 4 As shown, a protrusion 907 is fixedly connected to the lower part of the movable plate 903, and a groove 910 is provided on the inner surface of the fixed plate 908. The clamping plate 905 is movably engaged with the fixed plate 908. The protrusion 907 under the clamping plate 905 presses into the groove 910 inserted into the fixed plate 908 on the outside of the colored non-woven fabric, which improves the clamping force and prevents loosening.

[0036] like Figure 1and Figure 5 As shown, there are two sets of racks 12, which are located on one side above the displacement plate 6. The racks 12 are meshed with the gears 13. When the displacement plate 6 moves, it drives the fixed block 11 and the racks 12 to move left and right. When the racks 12 move, they drive the second screw 14 inside the gear 13 to rotate. The rotation of the second screw 14 drives the external movable sleeve 15 and the pressure block 17 below to rise and fall.

[0037] like Figure 5 As shown, the second screw 14 is threadedly connected to the movable sleeve 15, and the second slide rods 18 are fixedly connected to the upper two sides of the pressure block 17. The second slide rods 18 are slidably connected to the bracket 10. During the lifting and lowering process, the pressure block 17 slides in the bracket 10 through the second slide rods 18 on the upper two sides, thereby improving the stability of the pressure block 17 during the lifting and lowering process.

[0038] The working principle of this practical application is as follows: First, connect the external power supply. Then, place the colored non-woven fabric in the clamping mechanisms 9 on both sides. Next, rotate the first screw 901 inside the upper part of the displacement plate 6, causing the first screw 901 to move threadedly within the displacement plate 6. This pushes the moving plate 903 and the clamping plate 905 below to adhere to the surface of the colored non-woven fabric. During the clamping process, the clamping plate 905 is pushed and squeezed by multiple sets of springs 906 above, and the anti-slip pad 909 enhances the overall anti-slip performance. The protrusion 907 below the clamping plate 905 presses into the groove 910 inside the fixed plate 908 inserted outside the colored non-woven fabric, increasing the clamping force and preventing loosening. Then, turn on the motor switch at the bottom right side of the test platform 1, which drives the lead screw 5 to rotate. The rotation of the lead screw 5 drives the two sets of displacement plates 6 and the colored non-woven fabric inside to stretch to both sides for testing. When the two sets of displacement plates 6 move outward, they drive the two sets of fixed blocks 11 and racks 12 above to move. During the movement, the inner gear 13 and the inner second screw 14 are rotated. When the second screw 14 rotates, it drives the outer movable sleeve 15 and the lower pressure block 17 to descend, thereby squeezing the colored nonwoven fabric. When testing the tensile strength, the displacement sensor 902 inside the displacement plate 6 measures the distance moved by the two sets of displacement plates 6. The first pressure sensor 8 on the rear side of the displacement plate 6 senses the tensile force on both sides. At the same time, the second pressure sensor 16 above detects the pushing force. The signal data obtained by the displacement sensor 902, the first pressure sensor 8 and the second pressure sensor 16 are transmitted to the signal processing module 3. The signal processing module 3 processes and analyzes the signal and then transmits it to the display 4 for display by the staff. Finally, after the test is completed, the colored nonwoven fabric is released by the above steps. In this way, the use of the colored nonwoven fabric tensile testing device is completed.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
