Description

Technical Field

[0001] The present invention belongs to the technical field of strength detection, and specifically relates to a strength detection device for the production and processing of recycled polyester filaments. Background Art

[0002] Recycled polyester filaments are fiber products made from recycled polyester PET as raw materials, injecting colorants for coloring in a molten state, and processed through drawing, bulking, etc. In the production process of recycled polyester filaments, strength detection is a key link. Through strength detection, key indicators such as the tensile properties and elongation at break of recycled polyester filaments can be evaluated, thereby judging their adaptability and durability in actual applications.

[0003] The utility model patent application with the publication number CN217638343U discloses a tensile test device for the production of polyester network yarns, including: a device base, on the right side of which a motor is installed; a first connecting plate, which is slidably installed left and right on the top right side of the device base, and a tensile force sensor is fixedly connected to the left side of the first connecting plate; a second connecting plate, which is slidably installed left and right on the inner side of the top of the device base, and a fixing plate is fixedly connected to the left side of the top of the device base; a display, which is installed on the rear side of the top of the device base; a connecting rod, and connecting rods are threadedly connected to the inner sides of the second connecting plate and the fixing plate respectively. This tensile test device for the production of polyester network yarns is convenient for automatically testing the tensile degree of polyester network yarns, with relatively high test accuracy, and is also convenient for fixing polyester network yarns, and it is not easy for polyester network yarns to slip out of the device during the stretching process.

When the filament bounces, it may cause harm to personnel. Moreover, the bouncing filament may wind around the surfaces of other components on the device. When the surfaces of other components malfunction or need to be cleaned due to filament winding, it will cause the detection work to pause or interrupt, thereby reducing production efficiency.

With the cooperation of the pressing column 12 and the rotating column 11, the end of the regenerated polyester filament is pressed tightly, thus ensuring the stability during the strength testing process.

The middle part of the upper end surface of the right side of the test bench 1 is fixedly connected with the first motor 5, and the output end of the first motor 5 is fixedly connected with one end of the first threaded rod 4; One side of the upper end surface of the second mounting plate 18 is fixedly connected with an L-shaped plate 19. Two first sliding rods 20 are respectively slidably connected to both sides of the L-shaped plate 19. One end of the first sliding rod 20 is fixedly connected with a pressing plate 22. A spring 21 is sleeved on one side of the first sliding rod 20, and both ends of the spring 21 are fixedly connected with the pressing plate 22 and the L-shaped plate 19 respectively; Two second sliding rods 24 are slidably connected to one side of the L-shaped plate 19. One end of the second sliding rod 24 is fixedly connected with a rectangular block 25. Limit plates 26 are fixedly connected to both sides of the front end surface of the rectangular block 25. The limit plates 26 are inserted into the pressing plate 22. One side of the L-shaped plate 19 is fixedly connected with a second electric push rod 23. The piston end of the second electric push rod 23 is fixedly connected with one side of the rear end surface of the rectangular block 25. The second electric push rod 23 is electrically connected with the tension sensor 27; A display screen 2 is arranged on one side of the front end of the test bench 1, and the display screen 2 is electrically connected with the tension sensor 27; Specifically, recycled polyester filament is a fiber product made from recycled polyester PET as raw material, injected with colorants in a molten state for coloring, and processed through processes such as drawing and bulking. During the production process of recycled polyester filament, strength detection is a key link. Through strength detection, key indicators such as the tensile properties and elongation at break of the recycled polyester filament can be evaluated, thereby judging its adaptability and durability in actual applications. In the existing strength detection devices during use, when the filament is stretched to a certain extent, the filament will break and bounce. When the filament bounces, it may cause harm to personnel. Moreover, the bouncing filament may wind around the surfaces of other components on the device. When the surfaces of other components malfunction or need to be cleaned due to filament winding, it will cause the detection work to pause or interrupt, thereby reducing production efficiency. Additionally, extra time and manpower are required for cleaning and maintenance. Therefore, when this embodiment is in use, first fix the left end of the recycled polyester filament, then pass the recycled polyester filament through the through hole 16 and the inner cavity of the telescopic hose 3, and fix the right end of the recycled polyester filament. Then start the first motor 5 to drive the first threaded rod 4 to rotate, so that the right-side frame body 7 and the second mounting plate 18 slide to the right, and the recycled polyester filament and the telescopic hose 3 can be stretched. At the same time, the tension sensor 27 detects the tension value and displays the tension value on the display screen 2, and the strength detection work of the recycled polyester filament can be carried out. When the recycled polyester filament suddenly breaks, the telescopic hose 3 will block the broken recycled polyester filament to prevent it from bouncing. Moreover, when the recycled polyester filament breaks, the pressure value detected by the tension sensor 27 returns to zero. At this time, the second electric push rod 23 starts and drives the rectangular block 25 to move. The second sliding rod 24 slides on the L-shaped plate 19, so that the limiting plate 26 extends out of the groove of the pressing plate 22. At this time, the pressing plate 22 loses its limit, the spring 21 restores, and the upper and lower pressing plates 22 approach each other at the same time to clamp the recycled polyester filament, which can further prevent the recycled polyester filament from moving out of the telescopic hose 3, thus avoiding the situation of harm to personnel when the recycled polyester filament breaks and bounces, and also avoiding the situation that the bouncing recycled polyester filament winds around the surfaces of other components on the device and affects the normal progress of subsequent detection work. After the broken regenerated polyester filament is clamped by the pressing plate 22, the third motor 9 is started to drive the rotating column 11 to rotate, so that the rotating column 11 winds the broken regenerated polyester filament around its surface. Then, the fourth motor 29 is used to drive the second threaded rod 30 to rotate again, so that the pressing column 12 moves away from the rotating column 11, and the rotating column 11 and the pressing column 12 no longer clamp the regenerated polyester filament. Then, the second motor 8 is started to drive the first mounting plate 10 to rotate by 90 degrees. At this time, the end of the rotating column 11 is aligned with the collection box 6. Then, the first electric push rod 14 is started to drive the sliding disk 13 to move towards the end of the rotating column 11 until the sliding disk 13 is flush with the rotating column 11. At this time, the wound regenerated polyester filament will fall into the collection box 6 for collection. If the regenerated polyester filament is not broken, only need to drive the rotating column 11 and the pressing column 12 on either side to loosen the regenerated polyester filament, and then drive the rotating column 11 on the other side to rotate, then the winding work of the unbroken regenerated polyester filament can be realized. Repeating the above operations, the wound regenerated polyester filament can also be placed in the collection box 6, so that the regenerated polyester filament after the detection can be automatically wound and collected, which is convenient for sorting the regenerated polyester filament after the detection, and also improves the efficiency of the subsequent detection work; Thus, by using the bulletproof winding mechanism, during the strength detection work, the regenerated polyester filament can be covered, avoiding the situation of personnel being injured when the regenerated polyester filament breaks and bounces, and also avoiding the situation that the bounced regenerated polyester filament winds around the surfaces of other components of the device, affecting the normal progress of the subsequent detection work. And after the tensile force value is read, the regenerated polyester filament can be wound and concentrated at the same position, which is convenient for sorting the regenerated polyester filament after the detection, and also improves the efficiency of the subsequent detection work.

[0026] Working principle: Place both ends of the regenerated polyester filament to be strength-tested between the pressing column 12 and the rotating column 11 respectively. Then start the fourth motor 29 to drive the second threaded rod 30 to rotate, causing the slider 28 to move. With the cooperation of the pressing column 12 and the rotating column 11, both ends of the regenerated polyester filament are pressed tightly, thus ensuring the stability during the strength detection process. Make the regenerated polyester filament pass through the through hole 16 and the inner cavity of the telescopic hose 3. Then start the first motor 5 to drive the first threaded rod 4 to rotate, causing the right-side frame 7 and the second mounting plate 18 to slide to the right, and the regenerated polyester filament and the telescopic hose 3 can be stretched. At the same time, the tension sensor 27 detects the tension value and displays it on the display screen 2, and the strength detection work of the regenerated polyester filament can be carried out; when the regenerated polyester filament suddenly breaks, the telescopic hose 3 will block the broken regenerated polyester filament to prevent it from bouncing up. And when the regenerated polyester filament breaks, the pressure value detected by the tension sensor 27 returns to zero. At this time, the second electric push rod 23 starts and drives the rectangular block 25 to move. The second sliding rod 24 slides on the L-shaped plate 19, so that the limiting plate 26 extends out of the groove of the pressing plate 22. At this time, the pressing plate 22 loses its limit, and the spring 21 restores. The upper and lower pressing plates 22 move closer to each other at the same time to clamp the regenerated polyester filament, which can further prevent the regenerated polyester filament from moving out of the telescopic hose 3, thus avoiding the situation of causing harm to personnel when the regenerated polyester filament breaks and bounces up, and also avoiding the situation that the bounced regenerated polyester filament winds around the surface of the other components of the device, affecting the normal progress of the subsequent detection work; after the broken regenerated polyester filament is clamped by the pressing plate 22, the third motor 9 starts to drive the rotating column 11 to rotate, so that the rotating column 11 winds the broken regenerated polyester filament on its surface. Then use the fourth motor 29 to drive the second threaded rod 30 to rotate again, so that the pressing column 12 moves away from the rotating column 11, and the rotating column 11 and the pressing column 12 no longer clamp the regenerated polyester filament. Then start the second motor 8 to drive the first mounting plate 10 to rotate 90 degrees. At this time, the end of the rotating column 11 is aligned with the collection box 6. Then start the first electric push rod 14 to drive the sliding disk 13 to move towards the end of the rotating column 11 until the sliding disk 13 is flush with the rotating column 11. At this time, the wound regenerated polyester filament will fall into the collection box 6 for collection. If the regenerated polyester filament does not break, only need to drive the rotating column 11 and the pressing column 12 on either side to loosen the regenerated polyester filament, and then drive the rotating column 11 on the other side to rotate, and the winding work of the unbroken regenerated polyester filament can be realized. Repeat the above operation, and the wound regenerated polyester filament can also be placed in the collection box 6, so that the regenerated polyester filament after the detection can be automatically wound and collected, which is convenient for sorting the regenerated polyester filament after the detection, and also improves the efficiency of the subsequent detection work;Therefore, by using the bulletproof winding mechanism, the regenerated polyester filament can be covered during the strength detection work, avoiding the situation of injury to personnel when the regenerated polyester filament breaks and bounces, and also avoiding the situation that the bounced regenerated polyester filament winds around the surfaces of other components of the device, affecting the normal progress of subsequent detection work. Moreover, after the tensile force value is read, the regenerated polyester filament can be wound up and concentrated at the same position, facilitating the sorting of the detected regenerated polyester filament, and also improving the efficiency of subsequent detection work.
