Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, in particular to an electronic fabric strength tester. Background Art

[0002] At present, an electronic single fiber strength tester is generally used to detect the breaking strength and elongation rate of natural plush fibers. Due to the influence of many factors during the growth of naturally grown animal plush fibers, the coefficient of variation of the single fiber strength is above 30%. For a single sample, more than 300 single fiber strengths need to be tested, which is very cumbersome and difficult to implement in actual detection. Therefore, the standard ISO5079:1995 "Textile Fibres - Determination of the Breaking Strength and Elongation at Break of Single Fibres" issued by the International Organization for Standardization states that: "The most commonly used method for testing the breaking strength of natural fibers (especially wool and top fibers) is the bundle fiber method (see ISO3060 "Textiles - Wool Top Fibres - Determination of the Breaking Strength of Flat Bundles" and IWTO-32)".

[0003] The existing electronic single fiber strength tester mainly consists of a base, a motor, a lead screw, a slide table, upper and lower holders, a stress sensor and a rotary encoder. The upper holder is fixed on the slide table, and the lower holder is connected to the stress sensor fixed on the base. This electronic single fiber strength tester mainly has the following defects: 1. Since a stepping motor is used to move the slide table through a common lead screw, the moving speed of the slide table is slow. The strength of animal fibers varies greatly, especially the strength of bundle fibers. A very high moving speed must be used to effectively reduce the error caused by different stretching times of each fiber in the fiber bundle, which cannot meet the requirements of bundle fiber detection; 2. The clamping surfaces of the jaws on the upper and lower holders are rigid surfaces. If the clamping force is small, part of the animal fiber bundle will slip and break away. If the clamping force is large, the animal fiber bundle is easily clamped and broken. Therefore, the existing holders cannot be used for bundle fiber detection. In summary, the existing electronic single fiber strength tester is not suitable for the detection of animal plush bundle fibers.

[0004] For the existing Chinese patent CN201835042U electronic bundle fiber strength tester, when solving the above problems, its control panel is fixedly arranged on the base, and the display angle in the horizontal direction cannot be adjusted according to needs, which is not convenient for users to observe data and control the operation of the device.

[0032] Working principle: An electronic fabric strength tester of the utility model. During use, one end of the fabric to be tested is placed in front of the fixed block 5, and then the operating rod 15 in front of the fixed block 5 is rotated. The operating rod 15 drives the threaded rod 14 to rotate. The threaded rod 14 rotates in the inner cavity of the second threaded hole 13. Under the action of the thread, the clamping plate 11 moves backward. The clamping plate 11 moves in the inner cavity of the first limiting groove 17. The clamping plate 11 drives the second anti-slip pad 12 to move backward to clamp and fix the fabric. Then the top end of the fabric is placed in front of the movable block 7, and then the operating rod 15 in front of the movable block 7 is rotated, so that the clamping plate 11 on the front side of the movable block 7 moves backward to clamp and fix the fabric. Then the motor 4 is started through the control box 22. The motor 4 drives the lead screw 9 to rotate in the inner cavities of the first threaded hole 8 and the first bearing 6. The movable block 7 moves upward under the action of the first threaded hole 8. Due to the setting of the second limiting groove 18 on the movable block 7, the movable block 7 moves within a defined track, preventing the movable block 7 from rotating with the lead screw 9, thus ensuring the normal operation of the components;

[0033] This motor 4, control box 22, display screen 31 and button 32 are all prior arts, and their working principles are well-known and known to those skilled in the art;

[0034] When the angle of the control box 22 in the horizontal direction needs to be adjusted, the operator presses down the cross plate 30 and holds the top of the control box 22. The cross plate 30 drives the reed 29 to deform. The reed 29 drives the movable plate 24 to flip away from the block 23. The movable plate 24 flips around the pin shaft 28. The movable plate 24 drives the card slot 25 to flip away from the block 23 to unlock the control box 22. Then the control box 22 is rotated. Due to the setting of the connecting rod 21 and the third bearing 20 on the control box 22, the control box 22 rotates around the support column 19. After the angle of the control box 22 in the horizontal direction is adjusted to an appropriate position, the force on the cross plate 30 is released. The movable plate 24 flips towards the block 23 under the elastic action of the reed 29. The movable plate 24 drives the card slot 25 to flip to engage with the block 23 to fix the control box 22, thus facilitating the adjustment of the angle of the control box 22 in the horizontal direction and facilitating the user to observe data and control the operation of the device.
