Description

Technical Field

[0001] The present invention relates to the technical field of measuring instruments, and particularly to a fiber spinning breaking elongation rate measuring device. Background Art

[0002] Antibacterial composite polyolefin carbon fiber is an advanced composite material that combines antibacterial functions with the excellent properties of carbon fiber. This material usually achieves its unique antibacterial performance by adding antibacterial components during the manufacturing process to polyester or directly integrating them into the carbon fiber, making it suitable for multiple fields such as medical equipment, public facilities, sports equipment, and automotive interiors. To ensure that these fiber materials can achieve the expected effects in actual applications, it is particularly important to accurately evaluate their mechanical properties, such as breaking elongation rate. The breaking elongation rate is a key indicator for measuring the ductility of fiber materials, which reflects the ability of fiber materials to undergo permanent deformation when subjected to external forces.

[0003] Currently, when measuring the breaking elongation rate of fiber spinning, the common method involves a certain degree of manual operation: First, the fiber spinning is manually straightened and fixed between two clamps, which are used to fix the two ends of the fiber spinning. Then, through a driving system, the clamps are moved towards the side away from each other, applying a gradually increasing tensile force until the fiber breaks. However, this method not only takes time and effort due to the need to manually and precisely place the fiber spinning, but also, due to the influence of human factors, if the fiber is not properly tightened or placed inaccurately before testing, it may lead to deviations in the subsequent elongation rate calculation, affecting the accuracy of the measurement results. Summary of the Invention

[0004] In view of this, the present invention provides a fiber spinning breaking elongation rate measuring device, which can solve the disadvantages that the existing method is not only time-consuming and laborious but also may affect the accuracy of the measurement results due to the influence of human factors when measuring the breaking elongation rate of fiber spinning.

[0035] In use, first, push the trolley 1 to move to a specified position to measure the elongation rate of the fiber spinning. Then, put the reel wound with the fiber spinning on the air shaft 502, and make the leading end of the fiber spinning fall between two electric rollers 605 on two second movable blocks 604. Next, fix the reel wound with the fiber spinning by expanding the air shaft 502. Then, control the first motor 606 by the controller 2 to drive the bidirectional lead screw 607 to rotate, so that the bidirectional lead screw 607 in the first guide rail 601 drives two first movable blocks 602 to approach each other, so that the electric rollers 605 on the two first movable blocks 602 push the leading end of the fiber spinning upward above the funnel 7. At the same time, make the bidirectional lead screw 607 in the second guide rail 603 drive two second movable blocks 604 to approach each other, so that the electric rollers 605 on the two second movable blocks 604 push the leading end of the fiber spinning upward above the funnel 7 until the electric rollers 605 on the first movable block 602 and the second guide rail 603 limit the leading end of the fiber spinning above the funnel 7 and make the electric rollers 605 clamp the fiber spinning. Then, start to measure the elongation rate of the fiber spinning: The electric roller 605 is controlled by the controller 2 to convey the fiber spinning downward until the leading end of the fiber spinning passes through the funnel 7 and falls between the clamping members of the pneumatic clamp 11. Then, the controller 2 controls the pneumatic clamp 11 to clamp the leading end of the fiber spinning. Next, the controller 2 controls the second motor 1001 to drive the one-way lead screw 1002 to rotate, causing the one-way lead screw 1002 to drive the lifting plate 9 and the pneumatic clamp 11 to move downward, so that the pneumatic clamp 11 clamps the leading end of the fiber spinning and moves downward, making the leading end of the fiber spinning move downward through between the two upper clamping plates 14, and then making the leading end of the fiber spinning move downward through between the two lower clamping plates 14 until the bottom of the lifting plate 9 contacts the trolley 1. Then, the controller 2 controls the first electric push rod 12 to drive the clamping block 13 to move backward, causing the clamping block 13 to enter the arc-shaped groove 401. When the arc surface at the rear side of the clamping block 13 contacts the inner wall of the connecting block 4, the connecting block 4 will squeeze the two clamping blocks 13 on the same first electric push rod 12 to move closer to each other, compressing the first spring 1601, so that the two clamping blocks 13 drive the two clamping plates 14 to move toward the side close to the fiber spinning until the two upper clamping plates 14 clamp the upper end of the fiber spinning and the two lower clamping plates 14 clamp the lower end of the fiber spinning. Then, the controller 2 controls the pneumatic clamp 11 to release the leading end of the fiber spinning, and then the operator cuts the fiber spinning from the position at the bottom of the funnel 7. After that, the controller 2 controls the telescopic rods on the upper and lower sides to move away from each other, thereby driving the connecting blocks 4, the first electric push rods 12, the clamping blocks 13 and the clamping plates 14 on the upper and lower sides to move away from each other, so that the upper and lower clamping plates 14 apply tensile forces to the upper and lower ends of the fiber spinning, thereby straightening the fiber spinning. When the fiber spinning is straightened, at this time, under the action of the frictional force of the fiber spinning, the fiber spinning will drive the clamping plate 14 to stop moving, compressing the second spring 1602. When the touch switch 15 in the clamping block 13 contacts the clamping plate 14, the clamping plate 14 will press the touch switch 15. At this time, the touch switch 15 will control the laser emitter 1701 to emit a laser once. When the laser receiver 1702 receives the laser, it will calculate the distance from the laser emitter 1701 and send the calculated distance signal to the controller 2. Then, after the controller 2 receives the distance signal, it will be used as the "initial distance". After that, as the connecting blocks 4, the first electric push rods 12 and the clamping blocks 13 on the upper and lower sides continue to move away from each other, the clamping blocks 13 will drive the upper and lower clamping plates 14 to move away from each other through the touch switch 15, so that the upper and lower clamping plates 14 apply tensile forces to the upper and lower ends of the fiber spinning respectively to measure the elongation rate of the fiber spinning until the fiber spinning breaks. When the fiber spinning breaks, the second spring 1602 returns to its original state, and the second spring 1602 drives the clamping plate 14 to move away from the touch switch 15, so that the clamping plate 14 releases the touch switch 15. At this time, the touch switch 15 will control the laser emitter 1701 to emit a laser again,When the laser receiver 1702 receives the laser, it will calculate the distance between itself and the laser emitter 1701 again, and send the calculated distance signal to the controller 2. After the controller 2 receives the distance signal, it takes it as the "limit distance", and then calculates the elongation rate of the fiber spinning according to the "limit distance" and the "initial distance". Then, the controller 2 controls the telescopic rods on the upper and lower sides to move and reset towards the side close to each other, thereby driving the connecting blocks 4, the first electric push rods 12 and the clamping blocks 13 on the upper and lower sides to move and reset towards the side close to each other. Then, the controller 2 controls the first electric push rod 12 to drive the clamping block 13 to move forward and reset, so that the clamping block 13 leaves the arc-shaped groove 401. When the arc surface at the rear side of the clamping block 13 separates from the inner wall of the connecting block 4, the first spring 1601 returns to its original state, and the first spring 1601 drives the two clamping blocks 13 on the same first electric push rod 12 to move away from each other, so that the two clamping blocks 13 drive the two clamping plates 14 to move and reset towards the side away from the fiber spinning, thereby loosening the upper end of the fiber spinning after breakage by the two clamping plates 14 on the upper side, and loosening the lower end of the fiber spinning after breakage by the two clamping plates 14 on the lower side, so that the broken fiber spinning falls naturally under gravity. Then, the controller 2 controls the second motor 1001 to drive the one-way lead screw 1002 to reverse and reset, so that the one-way lead screw 1002 drives the lifting plate 9 and the pneumatic fixture 11 to move up and reset. In this way, the elongation rate of a section of fiber spinning can be automatically measured. Then, by repeating the above operations, the elongation rates of multiple sections of fiber spinning can be automatically measured, so as to use multiple groups of data to ensure the accuracy of the data; Finally, when not in use, the controller 2 controls the first motor 606 to drive the bidirectional lead screw 607 to reverse and reset, so that the bidirectional lead screw 607 in the first guide rail 601 drives the two first movable blocks 602 to move away from each other and reset, and at the same time, the bidirectional lead screw 607 in the second guide rail 603 drives the two second movable blocks 604 to move away from each other and reset, and the electric roller 605 loosens the fiber spinning. Then, the air shaft 502 contracts to loosen the reel wound with the fiber spinning, and then the reel wound with the fiber spinning can be taken off from the air shaft 502.

[0036] See Figure 10 and Figure 11 As shown, it further includes a cutting mechanism, and the cutting mechanism includes a second electric push rod 18 and a cutter 19; the second electric push rod 18 is installed at the top of the upper connecting block 4, and the second electric push rod 18 is electrically connected to the controller 2; the telescopic rod of the second electric push rod 18 is connected with the cutter 19, and the cutter 19 is used to extend into the funnel 7 to cut the fiber spinning.

[0037] By setting up a cutting mechanism, when the operator needs to cut the fiber spinning at the bottom of the funnel 7, the telescopic rod of the second electric push rod 18 can be extended by controlling the controller 2, so that the second electric push rod 18 drives the cutter 19 to move forward, thereby enabling the cutter 19 to extend into the funnel 7 to cut the fiber spinning. Then, the telescopic rod of the second electric push rod 18 is shortened by controlling the controller 2, so that the second electric push rod 18 drives the cutter 19 to move backward and reset. In this way, it is convenient for the operator to cut the fiber spinning.

[0038] See Figure 10 As shown, it further includes a fan 20; a fan 20 is connected to the front side of the telescopic rod on the upper side of the two-way push rod 3, and the fan 20 is electrically connected to the controller 2. The fan 20 is used to blow away the fiber spinning that falls after the clamping plate 14 is loosened.

[0039] By setting up the fan 20, when the controller 2 controls the telescopic rods on the upper and lower sides to move and reset towards the side close to each other, at the same time, the controller 2 is used to control the fan 20 to turn on, so that after the upper two clamping plates 14 loosen the upper end of the fiber spinning after it breaks, the fan 20 can blow the broken fiber spinning on the upper side forward, preventing the broken fiber spinning on the upper side from falling naturally onto the lower clamping block 13 and clamping plate 14 due to gravity, and avoiding affecting the measurement of the next section of fiber spinning. Then, the controller 2 is used to control the fan 20 to turn off.
