Description

Technical Field

[0001] The invention belongs to the technical field of textile testing, and in particular relates to a textile tensile strength testing device. Background Art

[0002] In today's industrial system, textile processing and production is undoubtedly a vital field. As an important product type, elastic textile fabrics are of vital importance for quality control. Among the many links to ensure the quality of elastic textile fabrics, tensile strength testing before leaving the factory is an indispensable step. At present, when conducting tensile strength tests on elastic textile fabrics, most detection devices rely heavily on manual observation of the fracture condition of the textiles during the entire detection process, and then record the data. However, this traditional method has a series of extremely obvious disadvantages.

[0003] First, from the perspective of error, manual observation has large errors. Human visual perception and reaction speed have natural limitations. In the process of observing the fracture of textiles, even extremely experienced inspectors find it difficult to accurately control the fracture timing of textiles. This is because in the actual inspection process, the fracture of textiles often occurs in an instant, and human vision may not be able to capture this critical moment in the first place. At the same time, human reaction speed may not be able to make accurate judgments and records in time. Even if the inspectors are fully focused, they may miss the best recording time due to momentary negligence or misjudgment, which ultimately leads to inaccurate test data.

[0004] Secondly, from the perspective of work efficiency and human resource utilization, manual control of the fracture condition greatly limits the ability of inspectors to handle other matters at the same time. During the inspection process, inspectors must concentrate on observing the status of the textiles without any distraction. This means that inspectors cannot handle other work tasks at the same time, such as organizing inspection reports, preparing for the next round of inspections, etc. This situation not only reduces the overall work efficiency, but may also cause a waste of human resources, because in many cases, inspectors may feel tired due to long-term focus on a single observation task, thus affecting work quality and efficiency. In addition, in some large-scale textile production companies, due to the heavy inspection tasks, a large number of inspectors are required, and the manual observation method further increases the demand for human resources, which undoubtedly increases the cost burden of the company.

[0005] To this end, we propose a textile tensile strength testing device to solve the above problems. Summary of the invention

[0021] 3. Optimize equipment performance:

[0022] 1. The transmission cooperation of the gear set and the pulley set in the joint control mechanism enables the servo motor to control the synchronous rotation of the two lead screws, avoiding the cost of adding additional drive equipment.

[0023] 2. At the moment when the elastic fabric breaks, the trigger control mechanism controls the electromagnetic plate to be energized through the PLC controller to generate magnetic repulsion, so that the permanent magnetic pressure plate presses the normally closed press switch, causing the servo motor to stop automatically, thereby avoiding the servo motor idling and wasting electricity.

[0026] 5. The sound and light alarm can be set up. When the detection is finished, the sound and light alarm can be controlled by the PLC controller to start and give reminders to the detection personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0037] A fracture monitoring mechanism 7 is fixedly arranged on the shell of the electric clamp 6 on the upper side, and the fracture monitoring mechanism 7 includes a monitoring roller 71 and a micro generator 72. Two support seats 12 are fixedly arranged on the shell of the electric clamp 6 on the upper side, and support blocks 13 and micro generators 72 are respectively arranged on the two support seats 12. The monitoring roller 71 is rotatably arranged on the support block 13, and the end of the monitoring roller 71 away from the support block 13 is transmission-connected to the micro generator 72. The micro generator 72 is electrically connected to the PLC controller 11. Through the arranged monitoring roller 71, the upper electric clamp 6 can be coordinated to move upward, and based on the support of the surface tension of the elastic fabric, the micro generator 72 can be coordinated to generate a corresponding electrical signal. According to the presence or absence of the generated electrical signal, the PLC controller 11 can automatically determine whether the elastic fabric is broken during the detection process, thereby avoiding the tediousness and inconvenience of manual observation.

[0038] A slider 14 is fixedly provided on the support block 13 and the micro generator 72, and a slide groove 15 matching with the slider 14 is provided on the support seat 12, and a return spring 16 is fixedly provided between the slider 14 and the slide groove 15. Through the cooperation of the slider 14 and the return spring 16, the monitoring roller 71 has a certain displacement space, which makes it easier for the monitoring roller 71 to closely adhere to elastic fabrics of different thicknesses.

[0039] A linkage mechanism 8 cooperating with the two lead screws 3 is provided on the base 1, and a trigger control mechanism 9 cooperating with the linkage mechanism 8 is provided on the base 1. The linkage mechanism 8 includes a servo motor 81, a gear set 82 and a pulley set 83. The servo motor 81 is fixedly arranged on the base 1, and the output end of the servo motor 81 is transmission-connected with one of the lead screws 3 through the gear set 82, and the two lead screws 3 are transmission-connected through the pulley set 83. Through the transmission cooperation of the gear set 82 and the pulley set 83, the servo motor 81 can control the two lead screws 3 to rotate synchronously, thereby avoiding the cost of adding additional driving equipment.

The normally closed push switch 94 is fixedly arranged on the inner bottom surface of the trigger box 91, and the normally closed push switch 94 is arranged opposite to the permanent magnetic pressure plate 93. The electromagnetic plate 92 is electrically connected to the PLC controller 11, and the normally closed push switch 94 is electrically connected to the servo motor 81. Through the electromagnetic plate 92, at the moment when the elastic fabric breaks, the electromagnetic plate 92 can be energized through the PLC controller 11 to generate magnetism to repel the permanent magnetic pressure plate 93 and press the normally closed push switch 94, so that the servo motor 81 automatically stops, thereby avoiding the servo motor 81 from idling and wasting electricity.

[0041] A power regulating mechanism 10 cooperating with the joint control mechanism 8 is fixedly arranged on the support frame 2 , and a PLC controller 11 is fixedly arranged on the support frame 2 . The PLC controller 11 is electrically connected to the fracture monitoring mechanism 7 and the trigger control mechanism 9 .

[0042] The power control mechanism 10 includes a control box 101, a micro electric cylinder 102 and a sliding rheostat 103. The control box 101 is fixedly arranged on one side of the support frame 2, the micro electric cylinder 102 is fixedly arranged on the control box 101, and the sliding rheostat 103 is fixedly arranged in the control box 101. The output end of the micro electric cylinder 102 is fixedly connected to the sliding end of the sliding rheostat 103 through the insulating block 18, and the sliding rheostat 103 is electrically connected to the servo motor 81. Through the micro electric cylinder 102, the sliding end of the sliding rheostat 103 can be controlled to move, thereby changing the resistance value of the sliding rheostat 103 connected to the servo motor 81, and then the output power of the servo motor 81 can be adjusted as needed. A travel switch 19 is fixedly arranged on the support frame 2, and the travel switch 19 is electrically connected to the micro electric cylinder 102. The travel switch 19 is convenient for the inspection personnel to accurately adjust the telescopic stroke of the micro electric cylinder 102, thereby accurately adjusting the power of the servo motor 81.

[0043] A sound and light alarm 21 is fixedly set on one side of the support frame 2, and the sound and light alarm 21 is electrically connected to the PLC controller 11. The sound and light alarm 21 can be set to start by the PLC controller 11 when the detection is completed, so as to remind the detection personnel.

[0044] The operating principle of the present invention is now described as follows:

[0045] When using the device to test the tensile strength, the lower end of the elastic fabric to be tested is clamped and fixed by the lower electric clamp 6, and then the upper end of the elastic fabric is straightened and clamped and fixed by the upper electric clamp 6;

[0046] After the elastic fabric is fixed, the servo motor 81 is started to rotate forward. Under the transmission cooperation of the gear set 82 and the pulley set 83, the two lead screws 3 will rotate synchronously, so that the fixed plate 4 can pull the upper electric clamp 6 upward through the electronic tensile gauge 5, and apply tension to the elastic fabric at the same time. During the detection process, the monitoring roller 71 will move upward synchronously with the upper electric clamp 6. Since the elastic fabric has a certain surface tension when it is not broken, it can provide support for the monitoring roller 71, so that the monitoring roller 71 can rotate during the upward movement. The generated rotational force will generate an electrical signal through the micro-generator 72 and feedback to the PLC controller 11. The period of generating the electrical signal belongs to the detection period. At this time, the PLC controller 11 does not take action. When it is pulled to a certain extent, causing the elastic fabric to break, the tension on the surface of the elastic fabric will disappear, and then at this time The monitoring roller 71 will not rotate, and thus will not generate a corresponding electrical signal. At this time, when the PLC controller 11 cannot receive the electrical signal sent by the micro-generator 72, the program set inside the PLC controller will be activated, so that the PLC controller 11 automatically records the peak data fed back by the electronic tensile gauge 5 when it breaks and displays it on the display screen of the PLC controller 11. At the same time, the PLC controller 11 will automatically control the electromagnetic plate 92 to be energized and magnetized, and synchronously control the sound and light alarm 21 to start, so as to remind the staff to end the test so that the staff can record data. At the moment when the electromagnetic plate 92 is energized and magnetized, it will repel the permanent magnetic pressure plate 93, so that the permanent magnetic pressure plate 93 presses the normally closed press switch 94, so that the contacts of the normally closed press switch 94 are separated, and then the servo motor 81 is automatically shut down to avoid the servo motor 81 idling and wasting electricity.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
