Description

Technical Field

[0001] This invention relates to the field of polyester filament testing technology, and specifically to a tensile property testing device for polyester filament production. Background Technology

[0002] Polyester filament is a synthetic fiber made from polyester fibers through a specific process, belonging to a major category of chemical fibers. Polyester chips are heated and melted, then extruded into fine filaments through a spinneret. These filaments are subsequently subjected to high-speed stretching and heat treatment to align their molecular structure, enhancing their strength and elasticity. Depending on the requirements, further treatments such as crimping, dyeing, and antistatic processes are applied to ultimately form polyester filaments of various specifications. Due to its high strength, wrinkle resistance, and durability, polyester filament has become one of the most widely used synthetic fibers in the modern textile industry. Despite its drawbacks such as poor moisture absorption, continuous improvements through blending and post-processing technologies have allowed it to penetrate various fields including clothing, home furnishings, and industry. With increasing environmental awareness, the future development of polyester will focus more on sustainability and functional innovation.

[0003] In existing technologies, tensile property testing of polyester filaments requires manual measurement of the filament length using tools such as vernier calipers and rulers, followed by cutting to standard dimensions using scissors or a cutter. The cut sample is then manually placed into the clamping mechanism of the testing device. This process is time-consuming and prone to size deviations due to tool inaccuracies or human error. Furthermore, manual sample cutting and placement require significant manpower and time, especially in high-frequency testing scenarios, where labor costs increase substantially and efficiency remains difficult to improve. As the applications of polyester filaments expand, such as to high-strength industrial yarns and functional fibers, the requirements for testing accuracy and speed continue to rise, making manual operation insufficient to meet the demands of automated and intelligent testing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tensile property testing device for polyester filament production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tensile property testing device for polyester filament production includes a testing platform.

Inside each mounting frame, a material cylinder with polyester filaments wound on its surface and a winding cylinder for winding excess polyester filaments are rotatably mounted. At the top of the other end of the testing platform, a testing mechanism for clamping and stretching the polyester filaments is installed. At the bottom of the testing platform, near the testing mechanism, a box for immersing the polyester filaments is installed. A protective mechanism is installed on the top of the testing platform above the testing mechanism. Near the two mounting frames on the top of the testing platform, a conveying mechanism is installed for transporting cut polyester filaments into the testing mechanism for testing.

[0006] Optionally, a first motor is mounted on one side of the outer wall of one of the mounting brackets, and the output end of the first motor is connected to the rotating part at one end of the take-up drum.

[0007] Optionally, the conveying mechanism includes two first slide grooves opened on the top of the testing table. A first slider is installed inside each of the two first slide grooves. A rectangular plate is installed at the top of each of the two first sliders. A rotating groove is opened inside each of the two rectangular plates. A first gear and a second gear that mesh with each other are rotatably installed inside each of the two rotating grooves.

[0008] Optionally, a second motor is installed on one outer wall of each of the two rectangular plates. The output ends of the two second motors are respectively connected to the rotating parts of the corresponding first gears. A circular block is installed inside each of the two second gears, and a circular hole for polyester filaments to pass through is opened at the center of each circular block.

[0009] Optionally, two fixing plates are installed on the outer wall of the two circular blocks that are close to each other, and two first electric telescopic rods are installed on the outer wall of the two fixing plates that are close to each other. The telescopic ends of the two first electric telescopic rods are jointly equipped with a first rubber clamp.

[0010] Optionally, the bottom of the testing platform has two second sliding grooves, each containing a second slider. The bottom of each second slider is fitted with a mounting plate, and the top of each mounting plate is fitted with a second electric telescopic rod. The testing platform has two first rectangular through slots for adjusting the movement of the second electric telescopic rods. The telescopic ends of the two second electric telescopic rods are fitted with mounting seats, and friction blocks are rotatably mounted inside the mounting seats.

[0011] Optionally, the testing mechanism includes two first grooves opened on the top of the testing table, with a lead screw rotatably installed inside each of the two first grooves. A third motor for driving the lead screw to rotate is installed on both outer walls of the testing table. A moving block is threaded onto the outer wall of each of the two lead screws, and a rotating block is rotatably installed at the end of each moving block near the conveying mechanism.

[0012] Optionally, each of the two rotating blocks has a second groove at the end away from the moving block, and a double-ended screw is rotatably installed inside each of the two second grooves. Two second rubber clamps are threaded onto the outer walls of the two double-ended screws, and a fourth motor for driving the double-ended screw to rotate is installed at the top of each of the two rotating blocks.

[0013] Optionally, the protective mechanism includes vertical rods installed on the outer walls of both sides of the testing platform. A third sliding groove is provided on the outer wall of the side of the two vertical rods that are close to each other. A third sliding block is installed inside the two third sliding grooves. A protective cover is installed between the two third sliding blocks. A connector for connecting to external refrigeration or heating equipment is installed at the center of the top of the protective cover.

[0014] Optionally, a second rectangular through slot is provided at the position of the testing platform directly above the box. A cover plate is rotatably installed inside the second rectangular through slot, and two sets of winding wheels are rotatably installed on the top of the cover plate. Steel wire rope is wound on the surface of both sets of winding wheels. A filter box is placed inside the box, and the moving ends of the steel wire rope away from the winding wheels are connected to the filter box.

[0015] The beneficial effects of this invention are: 1. In this invention, when testing the tensile properties of polyester filaments, the operator only needs to pull the polyester filaments wound on the surface of the barrel during the use of the device, and with the help of other equipment set up near the device, the polyester filaments can be accurately cut. Then the conveying mechanism can automatically transport the cut polyester filaments to the testing mechanism for clamping and tensile testing. In high-frequency testing scenarios, it can meet the needs of automated, intelligent and efficient testing of polyester filaments.

[0016] 2. In this invention, when the testing mechanism performs tensile testing on polyester filaments, two third sliders can be controlled to move downward together inside the corresponding third slide grooves, thereby driving the protective cover to move downward together and cover the surface of the testing mechanism, thus shielding and protecting the polyester filaments undergoing tensile performance testing, and preventing some of the polyester filament fragments from flying outwards when stretched to the point of breakage, which could cause injury to nearby workers.

[0017] 3. In this invention, the polyester yarn is rubbed sequentially by four friction surfaces of different materials on the friction block. This simulates the actual usage scenario where the polyester yarn rubs against these friction surfaces. With the subsequent testing by a testing agency to perform tensile performance testing on the polyester yarn after surface friction, it can be determined whether the tensile performance of the polyester yarn is significantly affected after surface wear. Subsequently, workers can optimize the production and processing technology of the polyester yarn according to different usage scenarios to improve the tensile performance of the polyester yarn under different usage scenarios.

[0018] 4. In this invention, since a connector is provided on the top of the protective cover, the externally pre-installed refrigeration and heating devices can connect the hoses at the output end to the connector in sequence, so that the cold air and hot air generated by the refrigeration and heating devices enter the interior of the protective cover in sequence, creating a low-temperature environment and a high-temperature environment for the polyester filament to be stretched, so as to achieve the effect of testing the tensile properties of the polyester filament in the low-temperature environment and the high-temperature environment.

After production and processing, the polyester filaments 4 are directly wound and stored in the spool 3. When it is necessary to test the tensile properties of the polyester filaments 4, the spool 3 with the polyester filaments 4 wound on its surface can be placed directly on top of one of the mounting frames 2, causing the polyester filaments 4 to be cut.

The two first linear motors can drive the two first sliders 20 to move back and forth inside the corresponding first slide grooves 6, thereby driving the two rectangular plates 7 to move back and forth on the top of the inspection table 1 for adjustment.

[0026] As a technical optimization of the present invention, a second motor is installed on one outer wall of each of the two rectangular plates 7. The output ends of the two second motors are respectively connected to the rotating parts of the corresponding first gears 26. A circular block 21 is installed inside each of the two second gears 27, and a circular hole 22 for the polyester filament 4 to pass through is opened at the center of each circular block 21. After the two second motors are started, they can drive the two first gears 26 to rotate synchronously, and in turn drive the two second gears 27 and the circular blocks 21 to rotate and adjust together inside the rotating groove 28.

[0027] As a technical optimization of the present invention, two fixing plates 23 are installed on the outer wall of the two circular blocks 21 that are close to each other, and two first electric telescopic rods 24 are installed on the outer wall of the two fixing plates 23 that are close to each other. The telescopic ends of the two first electric telescopic rods 24 are jointly equipped with a first rubber clamp 25. Figure 5 or Figure 6 As shown, after the telescopic ends of the two first electric telescopic rods 24 on the side of the two fixed plates 23 that are close to each other are extended, the two first rubber clamps 25 can be pushed to move in the direction of approach, so that the polyester thread 4 passing through the round hole 22 can be clamped and fixed.

[0028] As a technical optimization of the present invention, the bottom of the testing platform 1 has two second sliding grooves 10, and a second slider 29 is installed inside each of the two second sliding grooves 10. A mounting plate 30 is installed at the bottom of each of the two second sliders 29, and a second electric telescopic rod 31 is installed at the top of each of the two mounting plates 30. The interior of the testing platform 1 has two first rectangular through slots 8 for the movement and adjustment of the second electric telescopic rods 31. A mounting base 9 is installed at the telescopic ends of the two second electric telescopic rods 31, and a friction block 32 is rotatably mounted inside the mounting base 9. A second linear motor is pre-installed inside each of the two second sliding grooves 10. The two second linear motors can drive the two second sliders 29 to move back and forth within the corresponding second sliding grooves 10, thereby driving the two mounting plates 30, the two second electric telescopic rods 31, and the mounting base 9 to move and adjust together. A first driving device is pre-installed on one side of the outer wall of the mounting base 9. The output end of the first driving device is connected to the rotating part of one end of the friction block 32, thereby enabling the friction block 32 to rotate and adjust within the mounting base 9.

[0029] As an optimized technical solution of the present invention, the testing mechanism includes two first grooves 14 opened on the top of the testing table 1. A lead screw 33 is rotatably installed inside each of the two first grooves 14. Third motors for driving the lead screw 33 to rotate are installed on the outer walls of both sides of the testing table 1. Moving blocks 15 are threaded onto the outer walls of each of the two lead screws 33. Rotating blocks 34 are rotatably installed at the ends of each moving block 15 near the conveying mechanism. After starting, the two third motors can drive the two lead screws 33 to rotate inside the corresponding first grooves 14, thereby causing the two moving blocks 15 to move back and forth on the surface of the lead screws 33 for adjustment. Second driving devices are pre-installed inside each of the two moving blocks 15. The output ends of the two second driving devices are respectively connected to the rotating parts of the two rotating blocks 34, thereby driving the two rotating blocks 34 to rotate for adjustment.

[0030] As a technical optimization of the present invention, each of the two rotating blocks 34 has a second groove at the end away from the moving block 15. A double-ended screw 35 is rotatably installed inside each of the two second grooves. Two second rubber clamps 16 are threaded onto the outer walls of each of the two double-ended screws 35. A fourth motor for driving the double-ended screws 35 to rotate is installed at the top of each of the two rotating blocks 34. After starting, the two fourth motors can drive the two double-ended screws 35 to rotate, thereby causing the two second rubber clamps 16 to move towards or away from each other. After the two second rubber clamps 16 move towards each other, they can clamp and fix the polyester thread 4 placed in the gap between the outer walls on their adjacent sides.

[0031] As an optimized technical solution of the present invention, the protective mechanism includes vertical rods 11 installed on the outer walls of both sides of the testing platform 1. A third sliding groove 13 is provided on the outer wall of the side of the two vertical rods 11 that are close to each other. A third slider 36 is installed inside each of the two third sliding grooves 13. A protective cover 12 is installed between the two third sliders 36. A connector 37 for connecting to external refrigeration or heating equipment is installed at the center of the top of the protective cover 12. A third linear motor is pre-installed inside each of the two third sliding grooves 13. The two third linear motors can drive the two third sliders 36 to move up and down inside the corresponding third sliding grooves 13, thereby causing the protective cover 12 to move up and down between the two vertical rods 11 for adjustment.

[0032] As a technical optimization of the present invention, a second rectangular through slot 18 is provided on the testing platform 1 located directly above the housing 17. A cover plate 19 is rotatably installed inside the second rectangular through slot 18, and two sets of winding wheels 40 are rotatably installed on the top of the cover plate 19. Steel wire ropes 39 are wound on the surface of both sets of winding wheels 40. A filter box 38 is placed inside the housing 17, and the moving ends of the steel wire ropes 39 away from the winding wheels 40 are connected to the filter box 38. A third driving device is preset inside the testing platform 1. The output end of the third driving device is connected to the rotating part of one end of the cover plate 19, thereby driving the cover plate 19 to rotate and adjust inside the second rectangular through slot 18. Two fourth driving devices are preset on the top of the cover plate 19. The output ends of the two fourth driving devices are respectively connected to the rotating parts of the two sets of winding wheels 40, thereby driving the two sets of winding wheels 40 to rotate and adjust, so as to realize the winding and unwinding of the two sets of steel wire ropes 39, and consequently drive the filter box 38 to move up and down inside the housing 17.

[0033] In this invention, when using the device, the user places a spool 3 with polyester filaments 4 wound on its surface inside one of the mounting brackets 2. Then, the operator manually pulls the end of the polyester filaments 4, causing one end of the filaments 4 to pass through the circular holes 22 inside the two circular blocks 21 in sequence. Finally, the end of the polyester filaments 4 is wound around the surface of the take-up drum 5. The first motor drives the take-up drum 5 to rotate, allowing it to wind up the surface polyester filaments 4. Once the take-up drum 5 has wound up the surface polyester filaments 4 of the spool 3, the two circular blocks are controlled... The telescopic ends of the two sets of first electric telescopic rods 24 on the side of phase 21 extend together, driving the two first rubber clamps 25 to clamp and fix the polyester filament 4 located between the two rectangular plates 7. Then, with the help of the cutting equipment or cutting mechanism preset near the detection table 1, the part of the polyester filament 4 located between the winding drum 5 and one of the rectangular plates 7 is cut. At this time, the quality of the remaining polyester filament 4 on the surface of the drum 3 can meet the detection requirements, avoiding data deviation in the subsequent detection process due to surface friction, uneven oiling or mechanical damage to the surface polyester filament 4.

[0034] After removing the polyester filament 4 from the surface of the barrel 3, the polyester filament 4 located between the two rectangular plates 7 meets the testing requirements. A pre-set cutting device or mechanism can be controlled to cut the polyester filament 4 located between the barrel 3 and the other rectangular plate 7. The section of polyester filament 4 located inside the conveying mechanism then becomes the sample for subsequent tensile performance testing. By controlling the two first sliders 20 to move towards the testing mechanism within their corresponding first grooves 6, the cut section of polyester filament 4 can be synchronously moved between the two sets of second rubber clamps 16. Both ends of the polyester filament 4 are located in the gap between the two mating second rubber clamps 16, with the ends close to one end. By controlling the two fourth motors to drive the two... The double-headed screws 35 rotate together, causing the two mating second rubber clamps 16 to move towards each other, so that the two mating second rubber clamps 16 can clamp and fix the two ends of the polyester filament 4. The two third motors are controlled to drive the two screws 33 to rotate together, causing the two moving blocks 15 and the two second rubber clamps 16 to move towards each other and adjust to a suitable position. At this time, the two rotating blocks 34 can be controlled to rotate together, causing the corresponding two second rubber clamps 16 to wrap around the ends of the polyester filament 4, so that the two ends of the polyester filament 4 to be tested can be wrapped and clamped on the surface of the corresponding two second rubber clamps 16 respectively, improving the stability of clamping and fixing the two ends of the polyester filament 4 to be tested.

[0035] After the two ends of the polyester filament 4 are clamped and stabilized by two cooperating second rubber clamps 16, two third motors can be controlled to drive the two lead screws 33 to reverse together, driving the two moving blocks 15 and other components to move slowly in opposite directions, so that the polyester filament 4 located between the two sets of second rubber clamps 16 is slowly stretched, so as to achieve the effect of testing the tensile properties of the polyester filament 4 of a specified length.

[0036] When the aforementioned testing institution performs tensile testing on the polyester filament 4, the two third sliders 36 can be controlled to move downward together inside the corresponding third slide groove 13, thereby causing the protective cover 12 to move downward together and cover the surface of the testing institution, thus shielding and protecting the polyester filament 4 that is undergoing tensile performance testing, preventing some of the polyester filament 4 from flying outwards when stretched to the point of breakage, which could cause injury to nearby workers.

[0037] Clothing made of polyester filament 4 inevitably comes into contact with and rubs against other fabrics, such as denim jackets, during actual wear; when polyester industrial filament is used as tire cord, it needs to be tightly bonded to the rubber layer, and friction between the cord and rubber is inevitable during tire rolling; polyester conveyor belts used in the logistics industry for material transportation will inevitably rub against metal rollers or metal goods; when polyester geotextile is used for soil reinforcement, it will rub against soil particles or rocks. These are all scenarios where polyester filament 4 will experience friction in actual use. To further improve… To ensure comprehensive testing of the tensile properties of polyester filament 4, during the process of feeding a section of polyester filament 4 cut from the surface of the barrel 3 into the testing mechanism for clamping and fixing, the telescopic ends of the two second electric telescopic rods 31 can be controlled to extend upwards, pushing the mounting base 9 and the friction block 32 to move upwards together for adjustment. This allows the top of the friction block 32, whose four side walls are respectively bonded with denim fabric, rubber blocks, metal plates, and rock plates, to contact the polyester filament 4. By controlling the two second sliders 29 to move back and forth within the corresponding second slide grooves 10, one of the friction surfaces located at the top of the friction block 32 at this time is driven to contact the polyester filament 4. The polyester filament 4 rubs back and forth laterally, or moves back and forth within the corresponding first groove 6 with the help of two first sliders 20, driving the conveying mechanism to move longitudinally on the top of the detection table 1. This causes the polyester filament 4 to rub longitudinally against one of the friction blocks 32. While the polyester filament 4 is in contact with the friction block 32, two second motors can be controlled to drive the corresponding first gear 26 and second gear 27 to rotate synchronously. This causes the two sets of first rubber clamps 25 that hold and limit the ends of the polyester filament 4 to rotate together, thereby driving the polyester filament 4 to rotate as well. The process involves several steps to ensure that different parts of the polyester filament 4 can rub against the friction surface at the top of the friction block 32, thereby improving the authenticity and comprehensiveness of the frictional contact between the polyester filament 4 and the friction block 32. Finally, the conveying mechanism transports the polyester filament 4, after surface friction, to the testing mechanism for clamping and tensile testing. This allows the determination of whether the tensile properties of the polyester filament 4 are significantly affected after surface wear. Subsequently, staff can optimize the production and processing technology of the polyester filament 4 according to different application scenarios to improve its tensile properties under different application scenarios.

[0038] Meanwhile, since the telescopic ends of the two second electric telescopic rods 31 can push the mounting base 9 and the friction block 32 to move up and down during the telescopic process, and the polyester filament 4 to be tested is placed inside the conveying mechanism, the telescopic ends of the two second electric telescopic rods 31 can be controlled to push the friction block 32 to move upward, so that the friction block 32 can push the polyester filament 4 to deform upward. Then, the two first sliders 20 are controlled to move back and forth in the corresponding first slide groove 6, causing the polyester filament 4 to have more severe frictional contact with the top of the friction block 32 until the polyester filament 4 is broken by friction. The wear resistance of the polyester filament 4 can then be tested, improving the applicability of the device in the process of testing the relevant performance of the polyester filament 4.

[0039] Since a connector 37 is provided on the top of the protective cover 12, the externally pre-installed refrigeration and heating equipment can connect the output hoses to the connector 37 in sequence, so that the cold air and hot air generated by the refrigeration and heating equipment enter the interior of the protective cover 12 in sequence, creating a low temperature environment and a high temperature environment for the polyester filament 4 to be stretched, so as to achieve the effect of testing the tensile performance of the polyester filament 4 in the low temperature environment and the high temperature environment.

[0040] Meanwhile, since the polyester filament 4 will come into contact with relevant chemicals during actual use, these chemicals may be adsorbed on the surface of the polyester filament 4 fibers or penetrate into the interior, changing the molecular structure and affecting the tensile properties. At this time, a solution mixed with relevant chemicals can be injected into the housing 17. Then, the operator can manually pull the new polyester filament 4 wound on the surface of the barrel 3 and place it inside the two round holes 22. After clamping and fixing it with the help of two sets of first rubber clamps 25, the part near the barrel 3 is cut so that the new section of polyester filament 4 is located inside the conveying mechanism. The two moving blocks 15 are controlled to move in opposite directions inside the corresponding first grooves 14. After reaching the maximum distance, the two sets of second rubber clamps 16 are moved to a position away from the cover plate 19. Then, the cover plate 19 is controlled to rotate downward into the interior of the second rectangular through groove 18. Next, the two first sliders 20 are controlled to move in the corresponding first slide groove 6 towards the direction of the detection mechanism, which drives the conveying mechanism and the polyester filament 4 to move to a position close to the second rectangular through groove 18. At this time, the contact conveying mechanism clamps and limits the two ends of the polyester filament 4, so that the polyester filament 4 falls downward into the interior of the second rectangular through groove 18 and slides down into the filter box 38 inside the box 17 for a period of soaking treatment, simulating the scenario of the polyester filament 4 being used in a chemical environment.

[0041] After the polyester filament 4 is soaked inside the box 17 for a period of time, the two sets of winding wheels 40 at the top of the cover plate 19 can be controlled to wind up the two sets of steel wire ropes 39, driving the filter box 38 and the polyester filament 4 placed inside it to move upward to the top of the box 17, and filtering and drying the water adhering to the surface of the polyester filament 4. After the two sets of steel wire ropes 39 pull the filter box 38 to abut the bottom of the cover plate 19, the cover plate 19 can be controlled to rotate upward to the top of the test platform 1, causing the filter box 38 to rotate synchronously to the top of the test platform 1. The protective cover 12 of the protective mechanism is controlled to move downward to abut the top of the test platform 1. Air at the same temperature as the room temperature is delivered to the inside of the protective cover 12 through the external refrigeration or heating equipment, so that the polyester filaments 4 inside the filter box 38 can be dried quickly. After drying, the polyester filaments 4 are located above the test platform 1, and the staff can quickly take them out from the filter box 38 and place them inside the test mechanism for relevant tensile performance tests, thereby improving the efficiency of tensile performance testing of polyester filaments 4 in a chemical environment.
