Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically to a force measuring device for a fabric strength tester. Background Technology

[0002] A fabric strength tester is a device used to test the mechanical properties of fabrics. It can clamp fabric samples and apply tension to test the performance of the fabric samples. It is widely used in the textile industry.

[0003] Most existing fabric strength testing machines use only two clamps to hold the fabric in place. After securing it, the clamps are pulled to stretch the fabric for performance testing. However, this method of securing the fabric is often unreliable. During use, the fabric sample is prone to falling off or shifting, which may affect the fabric performance test and lead to inaccurate results. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a force measuring device for a fabric strength tester. The first clamping component can firmly clamp one end of the fabric, and the second clamping component can wrap the fabric around the surface of the second clamping component while clamping it, thereby increasing friction and making it difficult for the fabric to fall off or shift during performance testing, resulting in more accurate test results.

The driving assembly includes a motor, a screw fixedly connected to the output end of the motor, a slider threadedly connected to the outer wall of the screw, and a ball rolledly connected to the inner wall of the slider.

[0010] Preferably, the outer wall of the bottom of the first lower clamping block is fixedly connected to the outer wall of the slider, and the first lower clamping block meshes with the first upper clamping block. Through the design of the mutual meshing of the first lower clamping block and the first upper clamping block, the contact area between the fabric and the first clamping device is increased, the friction is increased, and the device can clamp the fabric more securely.

[0012] Preferably, the end of the handle away from the second lower clamping block passes through the workbench, the second lower clamping block engages with the second upper clamping block, and the end of the fixing post near the workbench is fixedly connected to the outer wall of the workbench. Through the handle, the fabric is wrapped around the surface of the second clamping assembly, making it difficult for the fabric to fall off during performance testing, thereby making the testing process more stable.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a force measuring device for a fabric strength tester, comprising: a worktable 1, a first limiting hole 10 formed on the outer wall of the worktable 1, a limiting rod 11 slidably connected to the inner wall of the first limiting hole 10, a driving assembly 2 fixedly connected to the outer wall of the worktable 1, a first clamping assembly 3 fixedly connected to the outer wall of the driving assembly 2, and a second clamping assembly 4 fixedly connected to the inner wall of the worktable 1. The fabric can be firmly clamped inside by the first clamping assembly 3 and the second clamping assembly 4, thereby effectively preventing the fabric from slipping during the test and making the test results more accurate.

[0024] The drive assembly 2 includes a motor 20, with a screw 21 fixedly connected to the output end of the motor 20. A slider 22 is threadedly connected to the outer wall of the screw 21, and a ball 23 is rolledly connected to the inner wall of the slider 22. The outer wall of the motor 20 is fixedly connected to the outer wall of the worktable 1. The end of the screw 21 away from the motor 20 passes through the worktable 1, and the screw 21 is rotatably connected to the inner wall of the worktable 1. The outer wall of the slider 22 is slidably connected to the inner wall of the worktable 1, and the outer wall of the ball 23 is rolledly connected to the inner wall of the worktable 1. Through the ball 23, the friction generated by the movement of the slider 22 is reduced, thereby reducing the impact of friction on the test results.

[0025] The first clamping assembly 3 includes a first lower clamping block 30, and a first upper clamping block 31 is provided on the top of the first lower clamping block 30. Both ends of the first lower clamping block 30 and the first upper clamping block 31 are threadedly connected to a first adjusting screw 32. The outer wall of the bottom of the first lower clamping block 30 is fixedly connected to the outer wall of the slider 22. The first lower clamping block 30 and the first upper clamping block 31 mesh with each other. This meshing design makes the device grip the fabric more securely, making it less likely for the fabric to fall off during performance testing.

[0026] The second clamping assembly 4 includes a second lower clamping block 40. A clamping plate 41 is fixedly connected to the inner wall of the second lower clamping block 40, and a handle 42 is fixedly connected to the outer wall of the clamping plate 41. A fixing post 45 is fixedly connected to the end of the second lower clamping block 40 away from the handle 42. A second upper clamping block 43 is provided on the top of the second lower clamping block 40. A second adjusting screw 44 is threaded to both ends of the second lower clamping block 40 and the second upper clamping block 43. A second limiting hole 46 is provided on the outer wall of both the second lower clamping block 40 and the second upper clamping block 43. The end of the handle 42 away from the second lower clamping block 40 passes through the workbench 1. The second lower clamping block 40 and the second upper clamping block 43 are engaged. The end of the fixing post 45 near the workbench 1 is fixedly connected to the outer wall of the workbench 1. After the fabric is clamped, the handle 42 can be rotated to make the fabric wrap around the surface of the second clamping assembly 4, reducing the risk of the fabric falling off during the test and making the test process more stable.

[0027] Working principle

[0028] In use, first pull the limiting rod 11 out from inside the first limiting hole 10 and the second limiting hole 46, then put one end of the fabric to be tested into the second clamping component 4 for fixing, then insert the limiting rod 11 into the first limiting hole 10 to limit the second clamping component 4, then put the other end of the fabric into the first clamping component 3 to complete the clamping and fixing of the fabric, and finally use the driving component 2 to make the first clamping component 3 pull one end of the fabric away from the second clamping component 4, so as to test the fabric, making the fabric less likely to fall off during the test, thereby improving the accuracy of the test results.

[0029] When it is necessary to perform performance testing on the fabric, firstly, the limiting bar 11 is pulled out from the first limiting hole 10 inside the workbench 1. Then, one end of the fabric to be tested is placed on the surface of the second lower clamping block 40. Subsequently, the second upper clamping block 43 is lowered by the second adjusting screw 44, so that the second upper clamping block 43 is engaged with the clamping plate 41 and fixed to one end of the fabric with the second lower clamping block 40. Then, the handle 42 is turned to rotate the second clamping assembly 4 and the fixing post 45, so that the fabric is wrapped around the surface of the second clamping assembly 4. Finally, the limiting bar 11 is inserted into the second limiting hole 46 to press the second clamping assembly 4. The limit switch prevents the tangled fabric from springing back, ensuring that one end of the fabric is firmly fixed inside the second clamping assembly 4. Then, the other end of the fabric is placed on top of the first lower clamping block 30, and the first upper clamping block 31 is moved downward by the first adjusting screw 32 to clamp the other end of the fabric. At this time, the motor 20 can be started to rotate the screw 21, thereby pushing the slider 22 to move. The ball 23 at the bottom of the slider 22 reduces the friction when the slider 22 moves, making the test results more accurate. The first clamping assembly 3 moves accordingly to perform performance testing on the fabric.
