Description

Technical Field

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

[0002] Spinning processing is to use a textile machine to twist many animal and plant fibers together to form threads or yarns, which can be used to weave cloth. Spinning mainly includes roving preparation, fine yarn preparation, yarn processing, and finished yarn inspection. After spinning processing, detecting the tensile properties of gauze is to evaluate the maximum 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, thus affecting its function.

[0003] In the prior art for detecting the tensile properties of gauze, it is necessary to fix the tensile detector on both sides of the gauze and apply tensile force manually from the outside. When the gauze is critically damaged, the reading of the tensile detector is read out. However, the operation of this process is extremely troublesome. At the same time, due to manual participation, when the operator's force is uneven, it causes a large error in the test results. Although there are also related devices for automatically detecting the tensile properties of gauze developed in the prior art, they can only simply pull the gauze automatically and cannot simulate different situations that the gauze encounters during actual use, so that the devices for automatically detecting the tensile properties of gauze in the prior art cannot meet people's needs for gauze detection. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a tensile testing device for gauze in spinning processing.

An upper clamping plate is commonly threadedly installed on the outer walls of the two second lead screws. Rubber pads are installed on the outer walls of the sides of the two lower clamping plates and the upper clamping plate that are close to each other.

[0009] Optionally, the automatic feeding mechanism includes a first sliding groove formed at the top of the first fixing plate. A first sliding block is installed inside the first sliding groove. The top end of the first sliding block is connected to a first moving plate through a first electric telescopic rod. Two second moving plates are slidably installed on the top of the first moving plate. Third grooves are formed on the inner walls of both sides of the first moving plate. Double-headed lead screws are rotatably installed inside the two third grooves.

[0010] Optionally, two sliding blocks are threadedly installed on the outer walls of the two double-headed lead screws. The outer walls of both sides of one end of the two second moving plates close to each other are connected to the corresponding sliding blocks. First rectangular grooves are formed on the tops of the two second moving plates. Rectangular plates are connected to the inside of the two first rectangular grooves through two second electric telescopic rods. A plurality of discharge pipes are installed on the tops of the two rectangular plates. Serrated sharp parts are provided at the tops of the plurality of discharge pipes.

[0011] Optionally, two second rectangular grooves are formed inside the two second moving plates at the ends far from each other. Cleaning pads are connected to the inside of the two second rectangular grooves through third electric telescopic rods.

[0012] Optionally, second sliding grooves are formed at the bottoms of the two third fixing plates. Second sliding blocks are installed inside the two second sliding grooves. The bottom ends of the two second sliding blocks are connected to the mounting plate through fourth electric telescopic rods.

[0013] Optionally, the cutting mechanism includes two fourth grooves formed at the bottom of the mounting plate. Third lead screws are rotatably installed inside the two fourth grooves.

[0014] Optionally, a plurality of industrial cameras are installed at the bottom of the mounting plate between the two fourth grooves. The plurality of industrial cameras cooperate to detect the appearance quality of the gauze.

[0015] Optionally, third sliding grooves are formed at the bottom ends of the two moving rods. Third sliding blocks are installed inside the two third sliding grooves. Cutting knives are rotatably installed at the bottom ends of the two third sliding blocks.

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

[0017] 1. In this invention, during the process of detecting the tensile property of the gauze, with the aid of the cutting mechanism, multiple components of the automatic feeding mechanism cooperate with each other, and different situations in the actual use process can be simulated for the gauze to be detected, so that the tensile property of the gauze can be detected more comprehensively, and the credibility and authenticity of the gauze tensile property detection can be improved.

[0018] 2. In this invention, after the gauze to be detected is placed on the tops of two second moving plates, the appearance quality of the gauze to be detected can be visually identified and detected by means of multiple industrial cameras. If there are defects such as breakage and stains on the surface of the gauze to be detected, the gauze is manually or removed from the tops of the two second moving plates by means of a preset manipulator, and other gauzes are replaced for detection. After the appearance quality of the gauze is qualified, subsequent other steps are carried out to avoid the gauze with defective appearance quality affecting the accuracy of the detection result.

[0019] 3. In this invention, through the arranged automatic feeding mechanism, the two ends of the gauze to be detected can be automatically placed inside the two clamping mechanisms. By clamping and fixing the two ends of the gauze with the upper clamping plate and the lower clamping plate, the effect of automatically feeding the gauze to be detected can be achieved, and there is no need to manually place and clamp and fix the two ends of the gauze in sequence, thus improving the detection efficiency of the gauze.

[0020] 4. In this invention, if the lengths of multiple pieces of gauze to be detected are different, after the gauze is placed on the tops of the two second moving plates and the appearance quality of the gauze is detected and passed by means of multiple industrial cameras, the two second moving plates are controlled to move in a direction away from each other, so that the length of the two second moving plates is greater than the length of the gauze. The redundant parts at the two ends of the gauze are roll-cut by the cutting mechanism arranged at the bottom of the mounting plate. At this time, the two second moving plates serve as backing plates, and the redundant parts at the two ends of the gauze to be detected can be automatically cut, avoiding the problem that the detection data of the gauze is different due to different lengths of the gauze and reliable detection data cannot be provided.

[0040] As a technical optimization solution of the present invention, second sliding grooves 31 are provided at the bottoms of both of the two third fixing plates 5. Second sliding blocks 33 are installed inside both of the two second sliding grooves 31. The bottom ends of both of the two second sliding blocks 33 are connected to a mounting plate 6 through fourth electric telescopic rods 34.

[0041] As a technical optimization solution of the present invention, a cutting mechanism includes two fourth grooves 35 provided at the bottom of the mounting plate 6. Third lead screws 36 are rotatably installed inside both of the two fourth grooves 35. Second moving blocks are threadedly installed on the outer walls of both of the two third lead screws 36. Moving rods 37 are installed at the bottom ends of both of the two second moving blocks. Two driving devices are preset on the outer walls on both sides of the mounting plate 6. The output ends of the two driving devices are respectively connected to one end of each of the two third lead screws 36, so as to drive the two third lead screws 36 to rotate inside the corresponding fourth grooves 35, and then drive the two second moving blocks and the moving rods 37 to move back and forth and adjust on the outer walls of the corresponding third lead screws 36.

[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. 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 model GR130XGA-WU in the prior art, and can detect stains and defects on the appearance of the gauze.

[0043] As a technical optimization solution of the present invention, third sliding grooves 38 are provided at the bottom ends of both of the two moving rods 37. Third sliding blocks 39 are installed inside both of the two third sliding grooves 38. Cutting knives 7 are rotatably installed at the bottom ends of both of the two third sliding blocks 39. Third linear motors are preset inside both of the two third sliding grooves 38. The two third linear motors can drive the two third sliding blocks 39 to move back and forth inside the corresponding third sliding grooves 38, and then drive the two cutting knives 7 to move and adjust at the bottom of the moving rods 37.

[0044] In the present invention, when the user uses the device, the gauze to be detected is placed on the tops of the two second moving plates 11 manually or by a preset mechanical arm. Then, the two double-headed screws 17 are controlled to adjust the distance between the two second moving plates 11 to ensure that the two ends of the gauze are flush with the ends of the two second moving plates 11 that are away from each other. Then, the two second sliders 33 are controlled to move inside the corresponding second chutes 31, driving the mounting plate 6 to move directly above the two second moving plates 11. By controlling the telescopic ends of the two fourth electric telescopic rods 34 to extend downward together, the distance between the multiple industrial cameras 32 at the bottom of the mounting plate 6 and the gauze is made closer, so that the multiple industrial cameras 32 can visually identify and detect the appearance quality of the gauze to be detected. If there are defects such as damage or stains on the surface of the gauze to be detected, the gauze is manually or removed from the tops of the two second moving plates 11 by means of a preset mechanical arm, and other gauzes are replaced for detection. After the appearance quality of the gauze is qualified, subsequent other steps are carried out to avoid the gauze with defective appearance quality affecting the accuracy of the detection results.

[0045] For the gauze that has passed the visual recognition detection, the first slider 14 can be controlled to move inside the first chute 9 in the direction close to the two second fixing plates 3, driving the upper first moving plate 10 and the second moving plate 11 to move together. Until the two second moving plates 11 move to the position between the two clamping mechanisms, by controlling the telescopic end of the first electric telescopic rod 15 to extend upward, the two second moving plates 11 are driven to move upward between the upper clamping plate 8 and the lower clamping plate 30. Then, by controlling the two first lead screws 13 to rotate together, the two first moving blocks 26 are driven to move in the direction of approaching or separating to adjust the distance between the two clamping mechanisms to match the length of the two second moving plates 11. At this time, the ends of the two second moving plates 11 that are away from each other are respectively located between the two corresponding upper clamping plates 8 and the lower clamping plates 30. By controlling the two double-headed screws 17 to reverse, the two second moving plates 11 are driven to move in the direction of approaching each other, so that the two ends of the gauze respectively fall on the tops of the two lower clamping plates 30. Finally, by controlling the multiple second lead 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 respectively clamp and fix the two ends of the gauze, and the effect of automatically loading the gauze to be detected can be achieved, without manually placing and clamping and fixing the two ends of the gauze in sequence, improving the detection efficiency of the gauze.

[0046] After the two clamping mechanisms stably clamp both ends of the gauze, control the two first lead screws 13 to reverse together, driving the two first moving blocks 26 to move away from each other, so that the two clamping mechanisms can pull both ends of the gauze, and the tensile property of the gauze can be detected. With the help of relevant instruments, the tensile force when the gauze breaks is recorded in real time, and multiple identical gauzes are detected repeatedly to improve the accuracy and authenticity of the detection data of the tensile property of the gauze.

[0047] If the lengths of multiple gauzes to be detected are different, the gauze can be placed on the tops of the two second moving plates 11. After the appearance quality of the gauze is detected through multiple industrial cameras 32, control the two second moving plates 11 to move away from each other, so that the length of the two second moving plates 11 is greater than the length of the gauze. Then, continue to control the telescopic ends of the two fourth electric telescopic rods 34 to move downward, and control the two third lead screws 36 to drive the two second moving blocks and the moving rod 37 to move and adjust synchronously at the bottom of the mounting plate 6, driving the distance between the two cutting knives 7 to be adjusted, so that the distance between the two 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 redundant parts at both ends of the gauze, control the two third sliders 39 to move back and forth inside the corresponding third chutes 38, and then drive 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 moving plates 11 serve as backing plates, and the redundant parts at both ends of the gauze to be detected can be automatically cut, avoiding the problem that the detection data of the gauze are different due to different lengths of the gauze, and reliable detection data cannot be provided.

[0048] At the same time, after the two clamping mechanisms clamp and fix both ends of the gauze, control the two second sliders 33 to move towards the direction close to the two second fixing plates 3 inside the corresponding second chutes 31, driving the mounting plate 6 to move directly above the gauze. Then, control the telescopic ends of the two fourth electric telescopic rods 34 to extend downward together, driving the two cutting knives 7 to contact the gauze, and with the help of the two third sliders 39 moving back and forth inside the corresponding third chutes 38, the two cutting knives 7 can cut incisions on the surface of the gauze to be detected, so that when the tensile property of the gauze is detected later, the reduced value of the tensile property of the damaged gauze can be measured, and thus the tensile property of the gauze can be detected more comprehensively;

[0049] Moreover, the distance between the two cutting knives 7 can be adjusted by the drive of the two third lead screws 36, so that the two cutting knives 7 can cut incisions at different positions of the gauze, facilitating testing the influence of the incision breakage at different positions on the tensile property of the gauze.

[0050] Since a plurality of discharge pipes 19 are installed on the tops of both rectangular plates 25, the plurality of discharge pipes 19 on the top of one rectangular plate 25 are drain 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 externally preset water conveying equipment and gas conveying equipment through pipelines, so that the plurality of discharge pipes 19 on the tops of the two rectangular plates 25 can drain water and discharge hot air or cold air respectively. 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 moving plates 11 to move below the gauze, and the plurality of discharge pipes 19 on the top of one rectangular plate 25 can be controlled to spray water upwards onto the surface of the gauze to lubricate the gauze. Then, during the subsequent tensile property detection of the gauze, it can be tested whether the tensile property of the gauze with water adsorbed inside decreases.

[0051] After detecting the tensile property of the gauze with water adsorbed inside, a new gauze is replaced, and the plurality of discharge pipes 19 on the top of the other rectangular plate 25 are controlled to spray hot air or cold air upwards below the gauze. Then, during the subsequent tensile property detection of the gauze, it can be tested whether the tensile property of the gauze at different temperatures decreases, so that the tensile properties of the gauze at different temperatures and different humidities can be further detected, further enriching the tensile property detection data of the gauze and facilitating the staff to further study the tensile properties of the gauze.

[0052] Moreover, since sharp parts are provided at the tops of the plurality of discharge pipes 19, after the two ends of the gauze are clamped and fixed by the two clamping mechanisms, when the two second moving plates 11 are controlled to move directly below the gauze, the telescopic ends of the plurality of second electric telescopic rods 23 are controlled to extend upwards together, driving the corresponding first rectangular grooves 21 of the two rectangular plates 25 to protrude upwards, so that the tops of the plurality of discharge pipes 19 are all in contact with the bottom end of the gauze. By means of the first slider 14 moving back and forth inside the first chute 9, the sharp parts at the tops of the plurality of discharge pipes 19 are driven to rub against the bottom end of the gauze, creating abrasion on the bottom of the gauze. Then, during the subsequent tensile property detection of the gauze, it can be tested how much the tensile property of the gauze with abrasion on the surface decreases.

[0053] When the two clamping mechanisms pull the two ends of the gauze until the gauze is damaged, debris will be generated after the gauze is damaged, and these debris will adhere to the surface of the rubber pad 29 on the side where the upper clamping plate 8 and the lower clamping plate 30 are close to each other. In order to avoid impurities adhering to the clamping parts of the upper clamping plate 8 and the lower clamping plate 30, which may affect the accuracy of the subsequent tensile property test data of the gauze, at this time, the first slider 14 can be controlled to move inside the first chute 9, driving the first moving plate 10 and the two second moving plates 11 to move between the two clamping mechanisms. By controlling the telescopic end of the first electric telescopic rod 15 to extend and controlling the two second moving plates 11 to move away from each other, the two second moving plates 11 are driven to be respectively located between the two upper clamping plates 8 and the lower clamping plates 30. Then, control the telescopic ends of the multiple third electric telescopic rods 24 at the far ends of the two second moving plates 11 to extend together, driving the multiple cleaning pads 20 to extend out of the corresponding second rectangular grooves 22 respectively, so that the multiple cleaning pads 20 are all abutted against the rubber pad 29 on the side where they are close to the corresponding upper clamping plate 8 and the lower clamping plate 30. As the two second moving plates 11 are controlled to move towards each other, the multiple cleaning pads 20 are driven to rub against the rubber pad 29 with which they are abutted, automatically wiping off the impurities adhering to the surface of the multiple rubber pads 29, achieving the effect of automatically cleaning and removing the impurities, and avoiding adverse effects of the impurities on the tensile property test of the gauze.
