Description

Technical Field

[0001] The invention relates to the technical field of spinning processing, and in particular to a gauze tensile strength detection device for spinning processing. Background Art

[0002] Spinning is the process of twisting many plant and animal fibers together into threads or yarns using a textile machine, which can be used to weave cloth. The earliest spinning machine was very simple in structure and was used in the 14th century. After the 18th century, people invented better spinning machines, which made the textile industry the largest industry. Spinning mainly includes roving preparation, spun yarn preparation, yarn processing, and finished yarn inspection. After the spinning process is completed, the tensile properties of the gauze are tested to evaluate the maximum load-bearing capacity of the gauze under tensile conditions, that is, the tensile strength. This test can ensure that the gauze will not break or deform easily during use, thereby affecting its function.

[0003] In the prior art, when testing the tensile properties of gauze, it is necessary to fix the tension detector on both sides of the gauze, apply tension manually from the outside, and read the reading of the tension detector when the gauze is critically damaged. The operation of this process is extremely troublesome. At the same time, due to manual participation, when the operator exerts uneven force, a large error is caused to the test result. Although relevant equipment for automatic detection of the tensile properties of gauze has also been developed in the prior art, it can only simply pull the gauze automatically, and cannot simulate the different situations encountered by the gauze in actual use, so that the equipment for automatic detection of the tensile properties of gauze in the prior art cannot meet people's needs for gauze detection.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, in the process of testing the tensile properties of gauze, with the help of the cutting mechanism, multiple components of the automatic feeding mechanism cooperate with each other, so that the gauze to be tested can be simulated in different situations during actual use, so that the tensile properties of the gauze can be tested more comprehensively, thereby improving the credibility and authenticity of the tensile performance test of the gauze.

[0018] 2. In the present invention, after placing the gauze to be tested on the top of the two second movable plates, the appearance quality of the gauze to be tested can be visually identified and tested with the help of multiple industrial cameras. If there are defects such as damage and stains on the surface of the gauze to be tested, the gauze is removed from the top of the two second movable plates manually or with the help of a preset robot, and replaced with other gauze for testing until the appearance quality of the gauze is qualified.

The two ends of the gauze are clamped and fixed by the upper clamping plate and the lower clamping plate, so as to achieve the effect of automatic feeding of the gauze to be tested. There is no need to manually place and clamp the two ends of the gauze in turn, thereby improving the detection efficiency of the gauze.

[0020] 4. In the present invention, if the lengths of multiple pieces of gauze to be tested are different, the gauze can be placed on the top of two second movable plates. After the appearance quality of the gauze is tested with the help of multiple industrial cameras, the two second movable plates are controlled to move away from each other so that the lengths of the two second movable plates are greater than the length of the gauze. The excess parts at both ends of the gauze are rolled and cut with the help of a cutting mechanism provided at the bottom of the mounting plate. At this time, the two second movable plates serve as pads to automatically cut the excess parts at both ends of the gauze to be tested, thereby avoiding the problem of different gauze lengths leading to different gauze test data and inability to provide reliable test data.

[0042] As a technical optimization solution of the present invention, a plurality of industrial cameras 32 are installed between the two fourth grooves 35 at the bottom of the mounting plate 6, and the plurality of industrial cameras 32 cooperate to detect the appearance quality of the gauze. The plurality of industrial cameras 32 are all industrial cameras of the model GR130XGA-WU in the prior art, which can detect stains and defects on the appearance of the gauze.

[0043] As a technical optimization solution of the present invention, the bottom ends of the two moving rods 37 are provided with third slide grooves 38, the insides of the two third slide grooves 38 are provided with third sliders 39, and the bottom ends of the two third sliders 39 are rotatably provided with cutting knives 7.

[0044] In the present invention, when the user uses the device, the gauze to be tested is placed on the top of the two second movable plates 11 manually or by a preset manipulator, and then the two double-headed screws 17 are controlled to drive the spacing between the two second movable plates 11 to be adjusted to ensure that the two ends of the gauze are flush with the ends away from the two second movable plates 11, and then the two second sliders 33 are controlled to move inside the corresponding second slide grooves 31 to drive the mounting plate 6 to move to just above the two second movable plates 11, and by controlling the telescopic ends of the two fourth electric telescopic rods 34 to extend downward together, the spacing between the multiple industrial cameras 32 at the bottom of the mounting plate 6 and the gauze is driven to be closer, so that the multiple industrial cameras 32 can take advantage of the situation to perform visual recognition detection on the appearance quality of the gauze to be tested. If there are defects such as damage and stains on the surface of the gauze to be tested, the gauze is removed from the top of the two second movable plates 11 manually or by means of a preset manipulator, and other gauze is replaced for testing until the appearance quality of the gauze is qualified, and then other subsequent steps are performed to avoid the gauze with defects in such appearance quality affecting the accuracy of the test results.

[0045] For the gauze that has passed the visual recognition inspection, the first slider 14 can be controlled to move in the first slide groove 9 toward the direction close to the two second fixed plates 3, and the first movable plate 10 and the second movable plate 11 above can be driven to move together, until the two second movable plates 11 move to the position between the two clamping mechanisms, and then the telescopic end of the first electric telescopic rod 15 is controlled to extend upward to drive the two second movable plates 11 to move upward to between the upper clamping plate 8 and the lower clamping plate 30, and then the two first screw rods 13 are controlled to rotate together to drive the two first movable blocks 26 to move in the direction of approaching or moving away, so that the distance between the two clamping mechanisms is equal to the distance between the two second The lengths of the movable plates 11 are adapted. At this time, the ends of the two second movable plates 11 that are away from each other are respectively located between the two corresponding upper clamping plates 8 and lower clamping plates 30. By controlling the two double-headed screws 17 to reverse, the two second movable plates 11 are driven to move in a direction close to each other, so that the two ends of the gauze fall on the top of the two lower clamping plates 30 respectively. Finally, by controlling the multiple second screws 28 to rotate together, the two upper clamping plates 8 are driven to move downward together, so that the two upper clamping plates 8 clamp and fix the two ends of the gauze respectively, thereby achieving the effect of automatically feeding the gauze to be inspected, without the need to manually place and clamp the two ends of the gauze in turn, thereby improving the inspection efficiency of the gauze.

[0046] After the two clamping mechanisms stably clamp the two ends of the gauze, the two first screw rods 13 are controlled to reverse together, driving the two first moving blocks 26 to move in opposite directions, so that the two clamping mechanisms can pull the two ends of the gauze, thereby achieving the purpose of testing the tensile performance of the gauze. With the help of relevant instruments, the pulling force when the gauze breaks is recorded in real time, and the test is repeated for multiple pieces of the same gauze to improve the accuracy and authenticity of the gauze tensile performance test data.

[0047] If the lengths of the multiple gauze to be tested are different, the gauze can be placed on the top of the two second movable plates 11, and after the appearance quality of the gauze is tested by multiple industrial cameras 32, the two second movable plates 11 are controlled to move away from each other, so that the lengths of the two second movable plates 11 are greater than the length of the gauze. Then, the telescopic ends of the two fourth electric telescopic rods 34 can be controlled to move downward, and the two third screw rods 36 can be controlled to drive the two second movable blocks and the movable rod 37 to move and adjust synchronously at the bottom of the mounting plate 6, so as to drive the spacing between the two cutting knives 7 to be adjusted, so that the two After the spacing between the cutting knives 7 is adapted to the specified detection length of the gauze, until the telescopic ends of the two fourth electric telescopic rods 34 drive the two cutting knives 7 to contact the excess parts at both ends of the gauze, the two third sliders 39 are controlled to move back and forth inside the corresponding third slide grooves 38, thereby driving the two cutting knives 7 to perform rolling cutting on the parts to be cut at both ends of the gauze. At this time, the two second movable plates 11 serve as pads to automatically cut the excess parts at both ends of the gauze to be detected, thereby avoiding the problem of different gauze lengths leading to different gauze detection data and the inability to provide reliable detection data.

[0048] At the same time, after the two clamping mechanisms clamp and fix the two ends of the gauze, the two second sliders 33 can be controlled to move in the corresponding second slide grooves 31 toward the direction close to the two second fixing plates 3, and after driving the mounting plate 6 to move to just above the gauze, the telescopic ends of the two fourth electric telescopic rods 34 are controlled to extend downward together, driving the two cutting knives 7 to contact the gauze, and with the help of the two third sliders 39, they move back and forth in the corresponding third slide grooves 38, so that the two cutting knives 7 can cut an incision on the surface of the gauze to be tested, so that when the tensile performance of the gauze is tested later, the value of the reduced tensile performance of the damaged gauze can be tested, so that the tensile performance of the gauze can be tested more comprehensively;

[0049] Moreover, the distance between the two cutting knives 7 can be adjusted by driving the two third screw rods 36, so that the two cutting knives 7 can cut incisions at different positions of the gauze, which is convenient for testing the influence of incision damage at different positions on the tensile properties of the gauze.

[0050] Since a plurality of discharge pipes 19 are installed on the top of the two rectangular plates 25, the plurality of discharge pipes 19 on the top of one of the rectangular plates 25 are drainage pipes, and the plurality of discharge pipes 19 on the top of the other rectangular plate 25 are exhaust pipes, the two rectangular plates 25 are respectively connected to external preset water supply equipment and gas supply equipment through pipelines, so that the plurality of discharge pipes 19 on the top of the two rectangular plates 25 can respectively discharge water and exhaust hot air or cold air. After the two ends of the gauze are clamped and fixed by the two clamping mechanisms, the first slider 14 can be controlled to drive the two second movable plates 11 to move to the bottom of the gauze, and the plurality of discharge pipes 19 on the top of one of the rectangular plates 25 can be controlled to spray water upward onto the surface of the gauze to lubricate the gauze, so that in the subsequent tensile performance test of the gauze, it can be tested whether the tensile performance of the gauze with water adsorbed inside is reduced.

[0051] After testing the tensile properties of the gauze with water absorbed inside, a new gauze is replaced, and a plurality of discharge pipes 19 on the top of another rectangular plate 25 below the gauze are controlled to spray hot air or cold air upward. In the subsequent testing of the tensile properties of the gauze, it is possible to test whether the tensile properties of the gauze at different temperatures are reduced, thereby further testing the tensile properties of the gauze at different temperatures and humidities, further enriching the tensile properties test data of the gauze, and facilitating the staff to further study the tensile properties of the gauze.

[0052] Moreover, since the top ends of the multiple discharge tubes 19 are all provided with sharp parts, after the two ends of the gauze are clamped and fixed by the two clamping mechanisms, the two second movable plates 11 are controlled to move to just below the gauze, and the telescopic ends of the multiple second electric telescopic rods 23 are controlled to extend upward together, driving the inside of the first rectangular groove 21 corresponding to the two rectangular plates 25 to extend upward, so that the top ends of the multiple discharge tubes 19 are all in contact with the bottom end of the gauze, and the first slider 14 moves back and forth inside the first slide groove 9, driving the sharp parts of the top ends of the multiple discharge tubes 19 to rub against the bottom end of the gauze, causing wear on the bottom of the gauze, so that in the subsequent test process of the tensile performance of the gauze, the gauze with worn surface can be tested to see how much its tensile performance has decreased.

[0053] The two clamping mechanisms pull the two ends of the gauze until the gauze is damaged. After the gauze is damaged, debris will be generated, and the debris will adhere to the surface of the rubber pad 29 on the side close to the upper clamping plate 8 and the lower clamping plate 30. In order to avoid impurities adhering to the clamping parts of the upper clamping plate 8 and the lower clamping plate 30, which will affect the accuracy of subsequent gauze tensile performance test data, the first slider 14 can be controlled to move inside the first slide groove 9 at this time, driving the first movable plate 10 and the two second movable plates 11 to move between the two clamping mechanisms, and by controlling the extension of the telescopic end of the first electric telescopic rod 15 and controlling the two second movable plates 11 to move in directions away from each other, the two second movable plates 11 are driven to be located respectively at Between the two upper clamping plates 8 and the lower clamping plates 30, the telescopic ends of the multiple third electric telescopic rods 24 at one end away from the two second movable plates 11 are controlled to extend together, driving the multiple cleaning pads 20 to extend from the inside of the corresponding second rectangular grooves 22, so that the multiple cleaning pads 20 are all in contact with the rubber pads 29 on the side close to their corresponding upper clamping plates 8 and lower clamping plates 30. As the two second movable plates 11 are controlled to move in the direction of approaching, the multiple cleaning pads 20 are driven to rub against the rubber pads 29 in contact with them, and impurities attached to the surfaces of the multiple rubber pads 29 are automatically wiped off, thereby achieving the effect of automatically cleaning and removing impurities, thereby avoiding the adverse effects of impurities on the tensile performance test of the gauze.
