Description

Technical Field

[0001] The present invention relates to the technical field of electronic fabric strength machines, and particularly to an electronic fabric strength machine with adjustable clamping force. Background Art

[0002] An electronic fabric strength machine drives a lead screw or other transmission device through a motor to drive a movable column or crossbeam to move, thereby applying a tensile force to a fabric specimen clamped on a fixture. By measuring the magnitude of the tensile force in real time and transmitting the signal to a control system, the control system processes and analyzes the data to obtain various mechanical property indexes of the fabric.

[0003] Since different fabric specimens may have different sizes, it is difficult for the prior art to adjust the clamping position according to the actual size of the specimen, resulting in difficult accurate fixation and testing of the specimen, and difficult simulation of the tensile force received by the fabric during actual use, thus making it difficult to comprehensively understand the tensile properties of the fabric and its applicability and quality in different application scenarios; if the tensile force is not properly adjusted during the test of the fabric specimen, it may cause the specimen to be suddenly overstressed and damaged, resulting in difficult smooth progress of the test, reducing the accuracy and reliability of the test results, and increasing the influence of human factors on the test results; in actual test work, it may be necessary to frequently replace fabric specimens of different types or specifications for testing. The prior art usually takes a lot of time to adjust the clamping force, and it is difficult to ensure that the fabric can be firmly clamped during the test, increasing the situations such as sliding, deformation or damage of the fabric during the test due to improper clamping force, making it difficult to better adapt to various specimens of different sizes and shapes, and reducing the compatibility of the equipment with different specimens and the accuracy of the test; it is difficult for the prior art to synchronously trigger the infrared thermal imager to work, thus making it difficult to ensure the consistency of the mechanical property test data and the microscopic deformation and fiber fracture images in time and space; Finally: During the use of the existing infrared thermal imager, it is difficult to solve the local microscopic deformation monitoring blind area, and at the same time, it is difficult to avoid motion blur, resulting in poor image clarity, and it is difficult to enhance the observation ability of the fiber fracture slope, and the practicability is relatively single.

[0029] The working principle of an electronic fabric strength tester with adjustable clamping force based on Embodiment 1 is as follows: First, when using this device, first place this device in the working area, and then connect the device to an external power source to provide the power required for the operation of this device. Second, the staff controls an external manipulator to pick up a fabric specimen, so that the external manipulator transports the fabric specimen above the machine table 1. Then, the moving mechanism 3 drives the clamping mechanism 34 to move, so that the clamping mechanism 34 moves to an appropriate position according to the position where the manipulator clamps the fabric specimen. Then, the external manipulator places the fabric specimen on the clamping mechanism 34, clamps the fabric specimen through the clamping mechanism 34, and then applies a certain pulling force to the fabric specimen through the pulling mechanism 33 to gradually deform the fabric specimen. During the process of applying the force value, the detecting member 337 measures the deformation amount and the applied force value of the fabric specimen in real time, and transmits the measured deformation amount and force value data to the control system 2 for data processing and analysis to obtain various mechanical property indexes of the fabric specimen, thus completing the operation of the electronic fabric strength tester. Thirdly, when the clamping mechanism 34 needs to be moved to an appropriate position, the detection mechanism 4 detects the position of the fabric and transmits an electrical signal to an external display screen. The staff controls the operation of two groups of second motors 37 through the data on the external display screen, so that the second motors 37 drive the bidirectional screw 38 to work. The bidirectional screw 38 drives two groups of second moving blocks 39 to move towards each other through the cooperation with the second sliding rod 310, so that the distance between the two groups of second moving blocks 39 gradually shortens. Then, the two groups of second moving blocks 39 drive the two groups of second sliding rods 310 to move, and the two groups of second sliding rods 310 drive the two groups of fixed blocks 311 to move relatively, so that the distance between the two groups of fixed blocks 311 gradually increases. Then, the two groups of fixed blocks 311 drive the second turntable 313 to rotate through the rotational connection with the two groups of fourth rotating rods 312. The second turntable 313 drives the gear set 315 to rotate, the gear set 315 drives the convex rod 316 to do circular motion, the convex rod 316 drives the first chute plate 317 to move downward in the limit frame 318, the first chute plate 317 drives the moving rod 32 to move downward, the moving rod 32 drives the pulling mechanism 33 to move downward, and the pulling mechanism 33 drives the clamping mechanism 34 to move downward, so that the two groups of clamping mechanisms 34 are moved to appropriate positions, and the clamping positions are adjusted according to the actual size of the specimen to achieve accurate fixation and testing. At the same time, the operation of a single group of second motors 37 can also be controlled. Through the downward movement of a single group of clamping mechanisms 34, the downward pulling of the fabric specimen is realized, simulating the tensile force received by the fabric specimen in actual use, and comprehensively understanding the tensile properties, applicability and quality of the fabric specimen in different application scenarios.

[0032] The push rod at the bottom of the first cylinder 333 is fixedly connected to a connecting seat 334. The lower part of the back of the connecting seat 334 is rotatably connected to a first rotating rod 335. The lower part of the back of the first rotating rod 335 is rotatably connected to a moving plate 336. A detection member 337 is fixedly connected to the left end of the moving plate 336. The moving plate 336 penetrates through the left and right ends of the second installation box 331 and is slidably connected to its interior.

[0033] On both the upper and lower sides of the front end of the first cylinder 333, speed regulating joints 338 are fixedly connected. The front end of the speed regulating joint 338 is fixedly connected to the gear rod on the back of the gear 339. The right end of the gear 339 meshes with a toothed plate 3310. The front end of the toothed plate 3310 is fixedly connected to a metal block 3311, and the metal block 3311 facilitates driving the toothed plate 3310 to move.

[0034] An electromagnetic slot is provided at the front end inside the second mounting box 331. The electromagnetic slot is composed of a chute provided at the front end inside the second mounting box 331 and six groups of electromagnetic blocks arranged at equal intervals in the chute. The electromagnetic blocks in the electromagnetic slot inside the second mounting box 331 are electrically connected to an external current output device and are magnetically adsorbed to the metal block 3311. The chute of the electromagnetic slot inside the second mounting box 331 is slidably connected to the metal block 3311. The electromagnetic slot at the front end inside the second mounting box 331 facilitates driving the metal block 3311 to move.

[0035] The back of the moving plate 336 is slidably connected to the mounting frame 332. The push rod at the bottom of the first cylinder 333 penetrates through the top of the mounting frame 332 and is slidably connected to its interior. The detecting member 337 is composed of an electric spring fixedly connected to the left end of the moving plate 336, and resistance strain gauges are adhesively connected to the electric spring wire axis in the directions of ±45°. The left end of the electric spring inside the detecting member 337 is fixedly connected to the first mounting box 31. The electric spring inside the detecting member 337 is electrically connected to an external power supply device.

[0036] In this embodiment: When a tensile force needs to be applied to the fabric sample, the six electromagnetic blocks in the electromagnetic slots in the second mounting box 331 are driven to work step by step by an external current output device, so that the metal block 3311 moves downward under the influence of the magnetic adsorption of the electromagnetic block. The metal block 3311 drives the toothed plate 3310 to move downward, and the toothed plate 3310 drives the two gears 339 to rotate. The two gears 339 drive the speed regulating joint 338 to rotate through the gear rods on their backs, so as to adjust the intake or exhaust speed of the first cylinder 333, control the telescopic speed of the first cylinder 333, and then drive the connecting seat 334 to move upward through the first cylinder 333. The connecting seat 334 drives the moving plate 336 to move leftward through the rotational connection with the first rotating rod 335, and applies a tensile force to the fabric sample through the movement of the moving plate 336. At the same time, by controlling the telescopic speed of the first cylinder 333, the fabric tensile force is indirectly adjusted to prevent the sample from being damaged due to excessive sudden force, enabling the test to proceed smoothly, improving the accuracy and reliability of the test results, reducing the influence of human factors on the test results. Moreover, during the leftward movement of the moving plate 336, the electric spring is energized by an external power supply device. The electric spring contracts as the moving plate 336 moves leftward and generates a stress field around it. This stress field affects the resistance value of the resistance strain gauge.
