Description

Technical Field

[0002] Composite fabric is a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. It is suitable for making textiles such as sofas and clothing. It is one of the indispensable fabrics for people's home life. High-strength composite fabric is a new type of textile material, usually made of multiple fibers or materials through a composite process. This fabric has excellent strength and durability and is often used in application scenarios that require high performance and special protection, such as: protective clothing, which can provide effective barrier and protection; sports equipment, with good tensile and wear resistance; industrial use, can withstand greater tension and wear.

[0003] When the existing fabric tensile tester clamps the fabric, on the one hand, since the fabric is installed manually, the fabric is relatively loose after installation. When the fabric is tensile tested, the deformation amplitude of the fabric is too large, and the test result is inaccurate. On the other hand, when the fabric is installed manually, it is easy to cause the position deviation of the upper and lower sides of the fabric. When the fabric is tested, it is easy to have a situation of large local stress, resulting in errors in the test results.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a tensile-resistant bidirectional activity detection device for high-strength composite fabrics.

[0031] like Figure 1-6 As shown, a high-strength composite fabric anti-tear bidirectional activity detection device includes:

[0032] Two clamping mechanisms 1 are used to fix and clamp the two ends of the composite fabric. The clamping mechanism 1 includes a U-shaped plate 2, and a winding roller 3 is rotatably installed in the U-shaped plate 2. It should be noted that the winding roller 3 and the U-shaped plate 2 are rotatably installed through a damping shaft. It is worth mentioning that a slot 22 is provided on the winding roller 3, and one end of the winding roller 3 rotates through the U-shaped plate 2 and is coaxially fixedly connected with a handle 4. Two fixed plates 5 are fixedly connected to the opening part of the U-shaped plate 2, and two plywood 6 are provided on the opposite sides of the two fixed plates 5. It is worth mentioning that anti-slip patterns 26 are provided on the opposite side walls of the two plywood 6 on the same side, and the anti-slip patterns 26 are arranged horizontally, and the two anti-slip patterns 26 are arranged correspondingly. Scales 38 are engraved on the opposite side walls of two of the plywood 6 located on the upper and lower sides, and both ends of the two plywood 6 are aligned with the U-shaped plate 2 inner wall is slidably connected, the side walls opposite to each other of the two clamping plates 6 are fixedly connected with first threaded rods 7, the ends of the two first threaded rods 7 away from the clamping plates 6 are respectively slidably penetrated through the two fixed plates 5, the two first threaded rods 7 are threadedly sleeved with threaded sleeves 8 on the outside, the threaded sleeves 8 are rotatably connected with the fixed plates 5, the U-shaped plate 2 is rotatably penetrated with a rotating shaft 9, the rotating shaft 9 and the two threaded sleeves 8 are connected through a first transmission mechanism 10, further, the first transmission mechanism 10 includes a first pulley 23 and a second pulley 24, the first pulley 23 is coaxially fixedly connected with the rotating shaft 9, the second pulley 24 is coaxially fixedly connected with the threaded sleeve 8, the first pulley 23 and the second pulley 24 are connected through a synchronous belt transmission, a first motor 11 is installed outside the U-shaped plate 2, and the driving shaft of the first motor 11 is coaxially fixedly connected with the rotating shaft 9.

[0033] Through the above technical features, when clamping the cloth, first pass one end of the cloth through between the two fixed plates 5 and insert it into the slot 22, then turn the handle 4, the handle 4 drives the winding roller 3 to rotate, the winding roller 3 can wind the cloth inserted in the slot 22, and then the other end of the cloth is wound and fixed by another winding roller 3 through the above operation until the cloth is tensioned, then the first motor 11 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the two threaded sleeves 8 to rotate through the first pulley 23 and the second pulley 24, because the threaded sleeve 8 is connected with the first threaded rod 7 through the internal thread, so when the two threaded sleeves 8 rotate, the two first threaded rods 7 will be driven to move relative to each other, and the two first threaded rods 7 drive the two clamping plates 6 to move relative to each other until the two clamping plates 6 clamp the cloth and fix it, when the cloth is clamped, the tension is high, and during the detection process, the deformation amplitude of the cloth is accurate and the detection result is accurate.

[0034] After the fabric is clamped, the tensile strength of the fabric can be tested. Therefore, a testing mechanism 12 is provided for testing the tensile strength of the composite fabric. The testing mechanism 12 includes two horizontal plates 13. The two horizontal plates 13 are fixedly connected by two vertical plates 14. Two connecting plates 15 are fixedly connected to the outside of the U-shaped plate 2. The two connecting plates 15 are slidably connected to the two vertical plates 14 respectively. A groove 16 is provided on the opposite side of the two vertical plates 14. A bidirectional threaded rod 17 is rotatably connected in the two grooves 16. A threaded block 18 is threadedly sleeved on the outside of the two bidirectional threaded rods 17. It should be noted that the two threaded blocks 18 located outside the same bidirectional threaded rod 17 are provided with a threaded sleeve that is connected to the bidirectional threaded rod. 17, the threads in the two threaded holes have opposite rotation directions, the four threaded blocks 18 are respectively fixedly connected to the four connecting plates 15, one of the cross plates 13 is provided with a cavity 19, one end of the two bidirectional threaded rods 17 extend into the cavity 19 and are connected through a second transmission mechanism 20. Furthermore, the second transmission mechanism 20 includes two third pulleys 25, the two third pulleys 25 are respectively coaxially fixedly connected to the two bidirectional threaded rods 17, and the two third pulleys 25 are connected through a synchronous belt transmission. A second motor 21 is fixedly mounted on the cross plate 13, and the drive shaft of the second motor 21 rotates through the cross plate 13 and is coaxially fixedly connected to one of the bidirectional threaded rods 17.

[0035] Through the above technical features, when inspecting the cloth, one of the bidirectional threaded rods 17 is driven to rotate by the second motor 21. Since the two bidirectional threaded rods 17 are connected by two third pulleys 25, one of the bidirectional threaded rods 17 will drive the other bidirectional threaded rod 17 to rotate. The two bidirectional threaded rods 17 drive the four threaded blocks 18 to move relative to each other. The four threaded blocks 18 drive the two U-shaped plates 2 to rise and fall through the connecting plates 15 connected thereto. The U-shaped plates 2 can perform pulling detection on the upper and lower sides of the cloth during the lifting process. The cloth can be inspected in multiple dimensions. The data generated during the cloth inspection is more in line with the actual situation, can effectively simulate the anti-pulling performance of the cloth in actual applications, and has a better detection effect.

[0036] When fixing the fabric, it is necessary to ensure that the fabric is aligned up and down to avoid stress concentration. Therefore, a positioning mechanism 27 is set up to clamp and align the composite fabric. The positioning mechanism 27 includes two transmission grooves 28 respectively arranged on the opposite side walls of the two U-shaped plates 2. A rotating sleeve 29 is rotatably connected in the two transmission grooves 28. A third motor 30 is embedded in one of the U-shaped plates 2. A sliding rod 31 is coaxially fixedly installed on the driving shaft of the third motor 30. Furthermore, a plurality of limit blocks 39 are provided on the outer wall of the sliding rod 31, and a slot 40 matching the limit block 39 is provided on the inner wall of the rotating sleeve 29. It should be noted that the limit between the limit block 39 and the slot 40 makes the sliding rod 31 and the rotating sleeve 29 aligned with each other. The rotating sleeves 29 can only perform relative movement of sliding up and down. When the sliding rod 31 rotates, the rotating sleeve 29 will also rotate accordingly. The sliding rod 31 slides through the two U-shaped plates 2 and the two rotating sleeves 29. A rotating tube 32 is rotatably embedded in the inner wall of the transmission groove 28. The rotating tube 32 and the rotating sleeve 29 are connected by a gear set 33. It is worth mentioning that the gear set 33 includes a gear 36 and a toothed disc 37 that mesh with each other. The gear 36 is coaxially fixedly connected to the rotating tube 32, and the toothed disc 37 is coaxially fixedly connected to the rotating sleeve 29. The second threaded rod 34 is connected to the inner thread of the rotating tube 32. The second threaded rod 34 slides through the U-shaped plate 2 and is fixedly connected to the positioning block 35.

[0037] Through the above technical features, before the cloth is clamped, the sliding rod 31 is driven to rotate by the third motor 30. Since the sliding rod 31 is slidably sleeved outside the rotating sleeve 29, the rotating sleeve 29 will be driven to rotate when the sliding rod 31 rotates. The rotating sleeve 29 drives the rotating tube 32 to rotate under the action of the gear 36 and the toothed disc 37. The rotating tube 32 drives the second threaded rod 34 to move. The second threaded rod 34 drives the positioning block 35 to move. Only according to the scale 38, the two positioning blocks 35 are aligned. When the cloth is installed, the upper and lower sides of the cloth are aligned, and then the cloth is clamped. During the detection, the situation where the local stress of the fabric is large can be avoided, thereby improving the accuracy of the cloth tensile resistance detection.

[0038] It should be noted that the tension setting and deformation rate setting in the fabric detection process and the installation of sensors in the equipment are all included in the existing tension detection equipment and are existing technologies, so they will not be described in detail.

[0039] Working principle:

[0040] 1) Correction of the placement position of the cloth strip: The sliding rod 31 is driven to rotate by the third motor 30. Since the sliding rod 31 is slidably sleeved outside the rotating sleeve 29, the rotating sleeve 29 is driven to rotate when the sliding rod 31 rotates. The rotating sleeve 29 drives the rotating tube 32 to rotate under the action of the gear 36 and the toothed disc 37. The rotating tube 32 drives the second threaded rod 34 to move. The second threaded rod 34 drives the positioning block 35 to move. According to the scale 38, the two positioning blocks 35 are aligned;

[0041] 2) Clamping the cloth strip: align one side of the cloth with the two positioning blocks 35, then pass one end of the cloth through the two fixing plates 5 and insert it into the slot 22, then turn the handle 4, the handle 4 drives the winding roller 3 to rotate, the winding roller 3 can wind the cloth inserted in the slot 22, and then through the above operation, the other end of the cloth is wound and fixed by another winding roller 3 until the cloth is tensioned, then the first motor 11 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the two threaded sleeves 8 to rotate through the first pulley 23 and the second pulley 24, because the threaded sleeve 8 is internally threaded with the first threaded rod 7, so when the two threaded sleeves 8 rotate, they will drive the two first threaded rods 7 to move relative to each other, and the two first threaded rods 7 drive the two clamping plates 6 to move relative to each other, until the two clamping plates 6 clamp the cloth;

[0042] 3) Testing the tensile strength of the fabric: The second motor 21 is used to drive one of the bidirectional threaded rods 17 to rotate. Since the two bidirectional threaded rods 17 are connected through two third pulleys 25, one of the bidirectional threaded rods 17 will drive the other bidirectional threaded rod 17 to rotate. The two bidirectional threaded rods 17 drive the four threaded blocks 18 to move relative to each other. The four threaded blocks 18 drive the two U-shaped plates 2 to rise and fall through the connecting plates 15 connected thereto. The U-shaped plates 2 can perform pulling tests on the upper and lower sides of the fabric during the lifting process.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
