Description

Technical Field

[0001] The present invention relates to the technical field of textile testing equipment, and particularly to a fabric bursting strength tester. Background Art

[0002] The phenomenon that a fabric bulges, expands and then ruptures under the action of a load perpendicular to the fabric plane is called bursting. The bursting strength of a fabric is an important mechanical index of the fabric. A fabric bursting strength tester is a professional instrument in the textile field for detecting the performance of a fabric's resistance to the bursting force perpendicular to the fabric plane. In the process of textile production and quality control, it is crucial. By simulating the bursting force scenarios that the fabric will encounter in actual use, it measures the key indexes of the fabric's bursting strength and bursting expansion degree, provides a quantitative basis for evaluating the quality, durability and applicability of the fabric, and helps producers and quality inspectors understand the performance of the fabric under different stress conditions to ensure that the textiles meet the corresponding quality standards and usage requirements.

[0003] Existing fabric bursting strength testers are difficult to quickly adapt to different fabric testing requirements. In the past, when facing multiple fabrics, the operation of replacing the bursting head was cumbersome, resulting in low testing efficiency. Because the appropriate bursting head could not be replaced in time, the accuracy of the test results was affected. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a fabric bursting strength tester to solve the problem that the operation of replacing the bursting head is cumbersome when the existing fabric bursting strength tester is testing.

[0005] To achieve the above purposes, the present invention is realized through the following technical solutions: A fabric bursting strength tester includes a housing. Both the left and right sides of the inner wall of the housing are fixedly connected with cylinders. The output ends of both cylinders are fixedly connected with lifting plates. The top of the lifting plate is fixedly connected with two motors. The output end of the left motor is fixedly provided with a rotating frame. The output end of the right motor is fixedly provided with a worm. The top of the worm is meshed and connected with a worm gear. The worm gear is rotatably connected with the rotating frame. The front end of the worm gear is fixedly connected with a rotating member. The surface of the rotating member is fixedly connected with a plurality of connecting boxes. A plurality of bursting heads are arranged outside the rotating member. A disassembly component is arranged inside the connecting box, and the disassembly component is used for disassembling the bursting head.

[0006] Preferably, the disassembly component includes a sliding block. The sliding block is slidably connected with the inner wall of the connecting box. The rear side of the sliding block is fixedly connected with two first springs. The rear ends of both first springs are fixedly connected with the inner wall of the connecting box. Two sliding grooves are opened at the top of the sliding block. Locking members are slidably connected inside both sliding grooves.

[0007] Preferably, one adjacent end of a plurality of bursting heads is fixedly connected with a connecting ring. Fixing grooves are opened at the bottom ends of a plurality of connecting rings.

[0008] Preferably, a fixing plate is fixedly connected to the rear side of the outer shell, a connecting frame is fixedly connected to the front side of the fixing plate, a rotating disk is rotatably connected to the top of the connecting frame, three rotating members are rotatably connected to the top of the rotating disk, sliding rods are slidably connected inside the three rotating members, the opposite sides of the three sliding rods are rotatably connected to the connecting frame, and the adjacent sides of the three sliding rods are rotatably connected to fixing members.

[0009] Preferably, threaded rods are rotatably connected between the top and the bottom of the inner walls of the three fixing members, clamping plates are threadedly connected to the surfaces of the threaded rods, and knobs are fixedly connected to the tops of the threaded rods.

[0010] Preferably, a limiting box is fixedly connected to the front side of the top of the connecting frame, two second springs are fixedly connected to the front side of the inside of the limiting box, a moving block is fixedly connected between the rear ends of the two second springs, and two locking blocks are fixedly connected to the rear side of the moving block.

[0011] Preferably, evenly distributed tooth blocks are fixedly connected to the front side of the rotating disk.

[0012] Preferably, four sliding rods are fixedly connected to the bottom of the inner wall of the outer shell, and the four sliding rods are slidably connected to the lifting plate.

[0013] Preferably, the two locking members are both slidably connected to the connecting box, and the front side of the sliding block penetrates through and extends to the front side of the connecting box.

[0014] Preferably, the adjacent sides of the three fixing members and the clamping plates are made of aluminum alloy, and anti-slip patterns are provided on the surfaces of the fixing members and the clamping plates.

[0015] Working principle: When the user is about to perform a bursting strength test on the fabric, if it is necessary to fix fabrics of different sizes, slide the moving block in the limiting box forward to squeeze the second spring, so that the locking block disengages from the evenly distributed tooth blocks on the front side of the rotating disk, rotate the rotating disk, drive the rotating members rotatably connected to the top to move. Since the sliding rods are slidably connected inside the rotating members, the sliding rods drive the fixing members rotatably connected to the adjacent sides to change positions, realizing the preliminary positioning of fabrics of different sizes. The user can also rotate the knob at the top of the threaded rod rotatably connected to the inner wall of the fixing member to adjust the position of the clamping plate threadedly connected thereto, accurately clamp fabrics of different thicknesses. The aluminum alloy material and anti-slip patterns of the fixing members and the clamping plates ensure the fixing effect. Start the cylinders fixedly connected to the left and right sides of the inner wall of the outer shell, and push the lifting plate to smoothly lift along the sliding rod to an appropriate height. Then, turn on the motor on the right side of the top of the lifting plate to drive the worm to rotate, causing the worm gear meshing with it and the rotating part fixedly connected to the front end to rotate. The connection box will then rotate. When the required bursting head rotates to the appropriate position, press the sliding block in the connection box to squeeze the first spring, causing the locking part to disengage from the fixing groove of the connection ring. Replace the bursting head, and complete the installation by operating in the reverse direction. Then start the cylinder to make the bursting head press against the fabric. At the same time, the left motor can be turned on to drive the rotating frame to rotate, adjusting the angle of the bursting head to simulate the force and obtain the fabric performance data.

[0016] The present invention provides a fabric bursting strength tester. It has the following beneficial effects: 1. In the present invention, the motor on the right side drives the worm to rotate. When the worm rotates, it drives the worm gear at the top to rotate, thereby driving the rotating part at the front to rotate. Thus, when testing, the rotating part can be rotated to quickly replace the bursting head, and when testing the bursting strength of different types of fabrics, there is no need to wait for a long time for the complicated operation of replacing the bursting head.

[0017] 2. In the present invention, the motor on the right side drives the worm to rotate, thereby driving the worm gear and the rotating part to rotate. When the motor on the left side rotates, it drives the rotating frame to rotate back and forth, thereby realizing the adjustment of the angle of the bursting head. The bursting strength of the fabric can be tested from different angles, simulating the non-vertical force received by the fabric during actual use. By adjusting the angle of the bursting head, the force-bearing situation can be more realistically simulated, and more comprehensive and accurate fabric performance data can be obtained.

[0018] 3. In the present invention, by pressing the sliding block to slide backward to squeeze the first spring at the rear side, at this time, the two locking parts slide in the sliding groove, and the two locking parts disengage from the fixing groove in the connection ring, thereby realizing the quick disassembly and replacement of the bursting head, enabling the tester to quickly switch bursting heads of different specifications to meet diverse testing requirements.

[0019] 4. In the present invention, by sliding the moving block forward to squeeze the second spring, at this time, the locking block disengages from the tooth block, and the rotating disk is rotated to drive the rotating part to move. At this time, the sliding rod slides in the rotating part, thereby adjusting the position of the fixing part, and realizing the fixation of fabrics of different sizes, avoiding the cumbersome operations of frequently replacing the fixing device or making complex adjustments for fabrics of different sizes, and shortening the test preparation time.

Specific embodiments

[0022] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to the attached Figure 1 - attached Figure 3 , an embodiment of the present invention provides a fabric bursting strength tester, including an outer shell 1. Both the left and right sides of the inner wall of the outer shell 1 are fixedly connected with cylinders 8. The output ends of the two cylinders 8 are both fixedly connected with lifting plates 10. The top of the lifting plate 10 is fixedly connected with two motors 11. The output end of the left motor 11 is fixedly provided with a rotating frame 14. The output end of the right motor 11 is fixedly provided with a worm 12. The top of the worm 12 is meshed and connected with a worm gear 13. The worm gear 13 is rotatably connected with the rotating frame 14. The front end of the worm gear 13 is fixedly connected with a rotating member 15. The surface of the rotating member 15 is fixedly connected with a plurality of connection boxes 16. A plurality of bursting heads 18 are arranged outside the rotating member 15. A disassembly component is arranged inside the connection box 16, and the disassembly component is used for disassembling the bursting head 18.

[0024] Specifically, when the user wants to conduct a bursting strength test on different types of fabrics, the motor 11 is started to drive the worm 12 to rotate. When the worm 12 rotates, it drives the worm gear 13 and the rotating member 15 to rotate. A plurality of connection boxes 16 fixedly connected to the surface of the rotating member 15 rotate accordingly. When the required bursting head 18 rotates to the appropriate position, the cylinders 8 located on the left and right sides of the inner wall of the housing 1 are started. The output ends of the cylinders 8 push the lifting plate 10 to move up and down, so that the bursting head 18 presses against the fabric for testing, and the rotating frame 14 can be driven to rotate. By adjusting the angle of the bursting head 18, the stress situation can be more realistically simulated, so as to obtain more comprehensive and accurate fabric performance data.

[0025] Refer to the appendix Figure 4 and the appendix Figure 5 The disassembly component includes a sliding block 30, which is slidably connected between the inner wall of the connection box 16. Two first springs 21 are fixedly connected to the rear side of the sliding block 30, and the rear ends of the two first springs 21 are fixedly connected to the inner wall of the connection box 16. Two sliding grooves 19 are formed at the top of the sliding block 30, and locking members 20 are slidably connected inside the two sliding grooves 19.

[0026] Specifically, press the sliding block 30 to make it slide backward to squeeze the two first springs 21 at the rear side. The locking members 20 slidably connected in the two sliding grooves 19 will slide in the sliding grooves 19 along with the movement of the sliding block 30. Finally, the two locking members 20 disengage from the fixing grooves 22 inside the connection ring 17, thus realizing the rapid disassembly of the bursting head 18. After that, the user can quickly replace the bursting head 18 with different specifications, and then operate in the reverse direction to release the sliding block 30. The first spring 21 rebounds to push the sliding block 30 to reset, driving the locking members 20 to re-engage with the fixing grooves 22 inside the connection ring 17 to complete the installation of the new bursting head 18. The whole process enables the tester to quickly switch the bursting heads 18 with different specifications to meet the diverse test requirements.

[0027] Refer to the appendix Figure 4 and the appendix Figure 5 One end of each adjacent bursting head 18 is fixedly connected with a connection ring 17, and fixing grooves 22 are formed at the bottom ends of the plurality of connection rings 17.

[0028] Specifically, the bursting head 18 is fixed and disassembled by the locking member 20 engaging with or disengaging from the fixing groove 22.

[0029] Refer to the appendix Figure 1 The rear side of the housing 1 is fixedly connected with a fixing plate 2. A connecting frame 3 is fixedly connected to the front side of the fixing plate 2. A rotating disc 4 is rotatably connected to the top of the connecting frame 3. Three rotating members 6 are rotatably connected to the top of the rotating disc 4. A sliding rod 7 is slidably connected inside each of the three rotating members 6. The opposite sides of the three sliding rods 7 are rotatably connected to the connecting frame 3, and the adjacent sides of the three sliding rods 7 are rotatably connected to a fixing member 23.

[0030] Specifically, when the user needs to fix fabrics of different sizes, the user slides the moving block 28 forward to squeeze the second spring 27, so that the locking block 29 disengages from the tooth block 5. Then, the rotating disk 4 is rotated. The rotation of the rotating disk 4 drives the three rotating members 6 connected to the top in a rotating manner to move. Since the sliding rods 7 are all slidably connected inside the three rotating members 6, the sliding rods 7 will slide inside the rotating members 6. And the fixing members 23 are rotatably connected to the adjacent sides of the three sliding rods 7. By moving the sliding rods 7, the position of the fixing members 23 is changed, so as to fix fabrics of different sizes. The whole operation avoids the cumbersome operations of frequently replacing the fixing device or making complex adjustments for fabrics of different sizes, and greatly shortens the test preparation time.

[0031] Refer to the appendix Figure 7 Between the top and the bottom of the inner walls of the three fixing members 23, threaded rods 31 are rotatably connected. Clamping plates 26 are threadedly connected to the surfaces of the threaded rods 31. Knobs 24 are fixedly connected to the tops of the threaded rods 31.

[0032] Specifically, by rotating the knob 24, the threaded rod 31 is driven to rotate. By rotating the threaded rod 31, the position of the clamping plate 26 can be adjusted to accurately clamp fabrics of different thicknesses.

[0033] Refer to the appendix Figure 8 On the front side of the top of the connecting frame 3, a limit box 25 is fixedly connected. Inside the front side of the limit box 25, two second springs 27 are fixedly connected. A moving block 28 is fixedly connected between the rear ends of the two second springs 27. Two locking blocks 29 are fixedly connected to the rear side of the moving block 28.

[0034] Specifically, by driving the locking block 29 to move through the moving block 28, the locking and disengagement of the locking block 29 and the tooth block 5 are realized, so as to control whether the rotating disk 4 can rotate, achieve flexible control of the rotation of the rotating disk 4, and meet the requirements for adjusting the rotating disk 4 when fixing fabrics of different sizes.

[0035] Refer to the appendix Figure 6 and the appendix Figure 8 On the front side of the rotating disk 4, uniformly distributed tooth blocks 5 are fixedly connected.

[0036] Specifically, when the locking block 29 is clamped between the tooth blocks 5, the rotation of the rotating disk 4 can be restricted, so that the position of the fixing member 23 is kept stable, and it is ensured that the structure adjusted to fix the fabric will not change randomly.

[0037] Refer to the appendix Figure 2 On the bottom of the inner wall of the housing 1, four sliding rods 9 are fixedly connected. The four sliding rods 9 are all slidably connected to the lifting plate 10.

[0038] Specifically, all four sliding rods 9 are slidably connected to the lifting plate 10, so that the lifting plate 10 can remain stable when lifted and lowered by the cylinder 8, avoiding shaking or deviation of the lifting plate 10 during movement.

[0039] Refer to the appendix Figure 4 and the appendix Figure 5 As shown, both locking members 20 are slidably connected to the connection box 16, and the front side of the sliding block 30 penetrates and extends to the front side of the connection box 16.

[0040] Specifically, the user directly operates the sliding block 30 outside the connection box 16, thereby easily controlling the movement of the locking member 20. Without complex tools or cumbersome operations, the disassembly and replacement of the bursting head 18 can be quickly achieved.

[0041] Refer to the appendix Figure 6 and the appendix Figure 7 As shown, the adjacent sides of the three fixing members 23 and the clamping plate 26 are all made of aluminum alloy. Anti-slip patterns are provided on the surfaces of the fixing members 23 and the clamping plate 26.

[0042] Specifically, the adjacent sides of the three fixing members 23 and the clamping plate 26 are all made of aluminum alloy. The aluminum alloy material has relatively high strength and can withstand a certain amount of pressure. It is not easy to deform when fixing the fabric, ensuring the fixing effect on the fabric. Moreover, the aluminum alloy material is relatively light and will not add too much weight to the overall device. Anti-slip patterns are provided on the surfaces of the fixing members 23 and the clamping plate 26, increasing the friction with the fabric, making the fabric less likely to slide during the fixing process. Even when the fabric is subjected to force during the bursting strength test, it can maintain a stable fixed state, thus ensuring the accuracy of the test results.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
