[0016] The present invention provides a device for detecting the tensile strength of a finished product of a high-performance fiber, which has the following beneficial effects:

[0017] 1. When placing fibers to prepare finished fabrics, the present invention places both ends of the fibers on the top of the lower clamping plates of the first clamping assembly and the second clamping assembly respectively, and only needs to start the hydraulic cylinder to make the sliding column on the driving block slide along the through groove of the driving plate. At this time, the guide column will guide the lifting plate under the limit of the frame, so that the lifting plate can be driven to move down and squeeze the roller frame, so that the upper clamping plate will be squeezed through the roller frame, the buffer plate, the buffer spring, the guide rod and the pressure wheel seat in turn and move to the lower clamping plate under the guidance of the slide rod, so as to clamp and fix the two ends of the fabric. At the same time, the tops of all the first clamping assemblies and the second clamping assemblies are in contact with the bottom of the lifting plate, so that all the first clamping assemblies and the second clamping assemblies can be controlled to be fixed at the same time without operating them one by one, thereby improving the speed of the fabric clamping process, and then improving the efficiency of the inspection. Moreover, during the inspection process, when the second clamping assembly moves due to the pulling force, the roller at its top can also slide on the bottom of the lifting plate, so as not to interfere with the clamping and fixing effect of the second clamping assembly.

[0018] When the gear train is in a state of being moved downward, the gear train is moved downwards and the gear train is moved upwards to release the gear, which in turn causes the gear train to move upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards, thereby preventing the gear train from moving upwards and downwards,

[0019] 3. After the cloth is clamped, the slide column will just move to the level of the through groove on the driving plate. At this time, as the slide column continues to move, the lifting plate will not continue to move downward, and when the driving block is in contact with the first magnet, it will push the first tooth plate to move, thereby driving the driving seat to move through the first tooth column, the second tooth column and the second tooth plate, which will cause the pull rod to pull the second clamping assembly. Therefore, after all the cloths are clamped, all the cloths will be automatically stretched and tested, thereby improving the continuity of operation. Moreover, since the diameter of the first tooth column is smaller than that of the second tooth column, the deceleration structure can be used to provide a larger driving force to increase the strength of the force. After the detection, when the driving block moves back, the first magnet will absorb the iron driving block, thereby first moving back synchronously to reset the second clamping assembly. When the rear end convex portion of the first tooth plate is blocked by the side frame, the driving block will separate from the first magnet, so that the driving block can continue to move back and reset.

[0020] 4. When placing cloth, the present invention can support the middle part of the cloth by the fixed support plate and the movable support plate so that the two ends thereof can be placed in the first clamping assembly and the second clamping assembly. When fixing cloth of different lengths, it is only necessary to pull the pull plate, and the positioning plate will drive all the card blocks to move out of the card slots on the pull rod, releasing the restriction on the pull rod, so that the position of each second clamping assembly can be adjusted according to demand. After adjustment, it is only necessary to push the pull plate to insert the card blocks into the card slots, so that the positions of all the pull rods can be fixed at the same time, which is beneficial to improving the convenience during operation. At the same time, the pull plate is quickly positioned by the second magnet, and the second clamping assembly will also drive the movable support plate to move synchronously during adjustment, without the need for additional operation, which is very convenient.

[0030] See also Figures 1 to 4 , the driving assembly 3 includes a hydraulic cylinder 301, a driving block 302 and a sliding column 303, the hydraulic cylinder 301 is arranged on the upper bottom surface of the frame 2, and one end of the hydraulic cylinder 301 is connected to the driving block 302, and sliding columns 303 are fixed on both sides of the driving block 302, the driving assembly 3 also includes a driving plate 304, a lifting plate 305 and a guide column 306, the outer side of the sliding column 303 is slidably connected to the driving plate 304, and the lifting plate 305 is fixed to the bottom of the driving plate 304, and the four ends of the top surface of the lifting plate 305 are provided with guide columns 306, and the guide columns 306 are slidably connected to the frame 2, a second clamping assembly 5 is arranged at the top center of the base 1, and the structure of the second clamping assembly 5 is consistent with that of the first clamping assembly 4, and a tension sensor 6 is connected to one side of the first clamping assembly 4, and the tension sensor 6 is fixedly connected to the base 1;

[0031] The specific operation is as follows: first, the two ends of the finished fiber cloth are placed on the top of the lower clamping plate 410 of the first clamping assembly 4 and the second clamping assembly 5, and after placing multiple cloths, it is only necessary to start the hydraulic cylinder 301 to make the sliding column 303 on the driving block 302 slide along the through groove of the driving plate 304. At this time, the guide column 306 will guide the lifting plate 305 under the limit of the frame 2, so that the lifting plate 305 can be driven to move downward and squeeze the roller frame 402, and when the buffer plate 403 starts to move downward, it will first squeeze the pressure wheel seat 406 through the buffer spring 405. At this time, the elastic force of the reset spring 409 is less than the buffer spring 405, so the reset spring 409 is The spring 409 will shrink first, so that the upper clamping plate 407 can move to the lower clamping plate 410 under the guidance of the sliding rod 408, and the cloth will be pressed on the lower clamping plate 410. At this time, the rack 411 will contact the gear 412. Therefore, as the buffer plate 403 continues to move downward, the buffer spring 405 will begin to shrink, and the buffer plate 403 will also slide along the outside of the guide rod 404. During this process, the rack 411 will push the gear 412 to make the lower clamping plate 410 rotate, thereby lifting the cloth and making the middle part of it suspended in the air to reduce interference. At the same time, the pressure wheel seat 406 will also slide on the outside of the upper clamping plate 407, so as not to interfere with the rotation of the upper clamping plate 407. Due to the elastic deformation performance of the buffer spring 405, the clamping force of the upper clamping plate 407 is not too large, and the fabric will still slide between the upper clamping plate 407 and the lower clamping plate 410, thereby avoiding excessive tension during clamping. After that, when the buffer plate 403 moves to the step outside the middle of the buffer spring 405, force will be applied through the guide rod 404, thereby avoiding the buffer spring 405 from affecting the stability of clamping due to elastic deformation, and the tops of all the first clamping components 4 and the second clamping components 5 are in contact with the bottom of the lifting plate 305, so that all the first clamping components 4 and the second clamping components 5 can be controlled to be fixed at the same time, without The operations are performed one by one, thereby increasing the speed of the cloth clamping process and further improving the efficiency of the detection. During the detection process, the tension sensor 6 can detect the tension exerted on each cloth so as to record its tensile strength. When the cloth is deformed due to the tension, the second clamping assembly 5 will also move due to the tension. At this time, the roller on its top can also slide on the bottom of the lifting plate 305, so as not to interfere with the clamping and fixing effect of the second clamping assembly 5. After the detection, as the driving block 302 moves back, the lifting plate 305 can be driven to move up, and the reset spring 409 will push the upper clamping plate 407 to move up, so that it is reset and releases the cloth.

[0032] Please refer to the figure Figure 2 , Figures 5 to 7, a stretching assembly 7 is connected to the upper end of one side of the frame 2, and the stretching assembly 7 includes a side frame 701, a first tooth plate 702 and a first magnet 703. The side frame 701 is fixed to the upper end of one side of the frame 2, and the middle bottom surface of the side frame 701 is slidably connected to the first tooth plate 702, and the first magnet 703 is fixed to one side of the first tooth plate 702. The stretching assembly 7 also includes a first tooth column 704 and a second tooth column 705. The bottom of the first tooth plate 702 is meshed with the first tooth column 704, and the bottom of the first tooth column 704 is meshed with the second tooth column 705, and the first tooth column 704 and the second tooth column 705 are both rotatably connected to the side frame 701. The stretching assembly 7 also includes a second tooth plate 706, a drive seat 707 and a pull rod 708. The bottom of the second tooth column 705 is meshed with the second tooth plate 706, and the bottom of the second tooth plate 706 is fixed with a drive seat 707, and the drive seat 707 is connected to the base 1 Sliding connection, the driving seat 707 is internally slidably connected with a pull rod 708, and the pull rod 708 is fixedly connected to the second clamping assembly 5, and an adjusting assembly 8 is arranged inside the driving seat 707, and the adjusting assembly 8 includes a pull plate 801 and a second magnet 802, a pull plate 801 is arranged on one side of the driving seat 707, and a second magnet 802 is fixed on the middle part of one side of the pull plate 801, and the second magnet 802 is magnetically connected to the driving seat 707, and the adjusting assembly 8 also includes a positioning plate 803, a clamping block 804 and a clamping groove 805, positioning plates 803 are arranged at the upper and lower ends of one side of the pull plate 801, and a clamping block 804 is arranged on one side of the positioning plate 803, and clamping grooves 805 are equidistantly provided on the outer side of the driving seat 707, a fixed support plate 9 is arranged at one end of the top surface of the base 1, and a movable support plate 10 is slidably connected to the top of the fixed support plate 9, and the movable support plate 10 is fixedly connected to the second clamping assembly 5;

[0033] The specific operation is as follows: just pull the pull plate 801, the positioning plate 803 will drive all the card blocks 804 to move out of the card slots 805 on the pull rod 708, and release the restriction on the pull rod 708, so that the position of each second clamping assembly 5 can be adjusted according to needs, and the second clamping assembly 5 will also drive the movable support plate 10 to move synchronously during the adjustment. After the adjustment, just push the pull plate 801 to insert the card block 804 into the card slot 805, so that the positions of all the pull rods 708 can be fixed at the same time, which is conducive to improving the convenience during operation. At the same time, the pull plate 801 is quickly positioned through the second magnet 802, and when placing the cloth, the fixed support plate 9 and the movable support plate 10 can be used to support the middle part of the cloth. After the cloth is clamped, the sliding column 303 will just move to the level of the through slot on the driving plate 304. When the driving block When 302 is in contact with the first magnet 703, it will push the first tooth plate 702 to move, thereby driving the driving seat 707 to move through the first tooth column 704, the second tooth column 705 and the second tooth plate 706, which will cause the pull rod 708 to pull the second clamping assembly 5. Therefore, after all the fabrics are clamped, all the fabrics will be automatically stretched and tested. Since the diameter of the first tooth column 704 is smaller than the diameter of the second tooth column 705, the deceleration structure can be used to provide a larger driving force to increase the strength of the force. After the test, when the driving block 302 moves back, the first magnet 703 will absorb the iron driving block 302, so that it will move back synchronously first to reset the second clamping assembly 5. When the rear end convex portion of the first tooth plate 702 is blocked by the side frame 701, the driving block 302 will separate from the first magnet 703, so that the driving block 302 can continue to move back and reset.

[0034] In summary, when using the high-performance fiber preparation product tensile strength testing device, first pull the pull plate 801, the positioning plate 803 will drive all the card blocks 804 to move out of the card slots 805 on the pull rod 708, so that the position of each second clamping component 5 can be adjusted according to needs, and the second clamping component 5 will also drive the movable support plate 10 to move synchronously during the adjustment. After the adjustment, only need to push the pull plate 801, the card block 804 can be inserted into the card slot 805, so that the position of all the pull rods 708 can be fixed at the same time, and the pull plate 801 can be quickly positioned by the second magnet 802. Secondly, the fiber preparation fabric product is placed on the fixed support plate 9 and the movable support plate 10, and its two ends are placed on the first clamping group The top of the lower clamping plate 410 of the component 4 and the second clamping assembly 5, and after placing multiple strips of cloth, only the hydraulic cylinder 301 needs to be started to make the sliding column 303 on the driving block 302 slide along the through groove of the driving plate 304. At this time, the guide column 306 will guide the lifting plate 305 under the limit of the frame 2, so that the lifting plate 305 can be driven to move downward and squeeze the roller frame 402, and when the buffer plate 403 starts to move downward, it will first squeeze the pressure wheel seat 406 through the buffer spring 405. At this time, the elastic force of the return spring 409 is less than the buffer spring 405, so the return spring 409 will shrink first, so that the upper clamping plate 407 can be moved to the lower clamping plate 410 under the guidance of the slide rod 408, and the cloth is pressed on the lower clamping plate 410. At this time, the rack 411 will The gear 412 contacts the buffer plate 403, so as the buffer plate 403 continues to move downward, the buffer spring 405 begins to contract, and the buffer plate 403 also slides along the outside of the guide rod 404. During this process, the rack 411 pushes the gear 412 to rotate the lower clamping plate 410, thereby lifting the cloth and making the middle part of it suspended in the air to reduce interference. At the same time, the pressure wheel seat 406 also slides on the outside of the upper clamping plate 407, so as not to interfere with the rotation of the upper clamping plate 407. Afterwards, when the buffer plate 403 moves to the step outside the middle part of the buffer spring 405, force is applied through the guide rod 404, so as to avoid the buffer spring 405 from affecting the stability of clamping due to elastic deformation. Then, after clamping the cloth, the slide column 303 just moves to the driving plate 3 04, the driving block 302 will fit with the first magnet 703, and will push the first tooth plate 702 to move, thereby driving the driving seat 707 to move through the first tooth column 704, the second tooth column 705 and the second tooth plate 706, and the pull rod 708 will pull the second clamping assembly 5. Therefore, after all the fabrics are clamped, all the fabrics will be automatically stretched and tested. Then, the tension sensor 6 can detect the tension exerted on each fabric so as to record its tensile strength. At the same time, when the fabric is deformed due to the tension, the second clamping assembly 5 will also move due to the tension. At this time, the roller on its top can also slide on the bottom of the lifting plate 305, so as not to interfere with the clamping and fixing effect of the second clamping assembly 5. Finally,When the driving block 302 moves back after detection, the first magnet 703 will absorb the iron driving block 302, so that it will move back synchronously first to reset the second clamping assembly 5. When the tail end convex part of the first tooth plate 702 is blocked by the side frame 701, the driving block 302 will separate from the first magnet 703, so that the driving block 302 can continue to move back and reset. As the driving block 302 continues to move back, it can also drive the lifting plate 305 to move up, and the reset spring 409 will push the upper clamping plate 407 to move up, reset it and release the cloth, so as to facilitate the unloading operation of the cloth after detection.
