Description

Technical Field

[0001] This invention relates to the field of yarn testing equipment technology, and in particular to an online testing mechanism for the quality of polymer-spun yarn. Background Technology

[0002] Compact spinning, also known as "aggregate spinning," is a ring spinning method that produces yarns with a more compact structure. Its core technology involves adding a aggregation device at the output end of the front roller. This allows the sliver to be aggregated before being twisted, achieving separation of drafting and aggregation. This avoids the friction distribution being affected by aggregation in the drafting zone, and the width of the drafted sliver is reduced after aggregation. After the compact spun yarn is produced, it is necessary to test the yarn from the same batch or different batches to ensure the quality of the yarn production.

[0003] Commonly used yarn testing equipment cannot simultaneously test large quantities of yarn from different batches and specifications. Furthermore, it can only test a single aspect of the yarn, making it inefficient to simultaneously test multiple quantities of different types of yarn from multiple perspectives. Common yarn testing methods typically divide the same batch of yarn into multiple portions for testing in different aspects to prevent interference between different aspects of the testing process and results. However, these different testing methods cannot be coordinated to ensure more accurate multi-faceted yarn testing results. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an online detection mechanism for the quality of aggregate spun yarn.

An arc-shaped groove is formed at the bottom of the tension detection plate along its length.

[0010] Preferably, a heating plate is installed on the inner wall of the conveying cylinder between two adjacent baffles. The heating plate is located on the side of the guide rod near the support plate. A scanner is installed on the inner wall of the conveying cylinder on the side of the guide rod near the moving plate. An electrostatic generator is installed on the inner wall of the conveying cylinder on the side of the scanner near the moving plate.

[0011] Preferably, one of the arc-shaped plates used to form the conveying cylinder has a second slot at its top end, and the other arc-shaped plate has a second block installed on its top side. The top of the placement plate has a fixing groove along its length, and the inner wall of the fixing groove near the fixing plate has several second conveying holes that match the first conveying hole.

[0012] Preferably, the support plate has an inner cavity, and the top of the inner cavity has a plurality of feeding holes, the top of the feeding holes being located on the side of the first limiting groove, and the bottom of the inner cavity having a through hole on the side near the moving plate.

[0013] Preferably, the support plate has a groove on the side away from the moving plate, the bottom end of the through hole is connected to the groove, a plurality of electric rotating shafts are rotatably installed on the inner wall of the groove, a winding wheel is installed on the outer wall of the electric rotating shaft, a first slot is provided on the top end of the fixed plate near the support plate, and a first locking block is installed on the bottom end of the support plate away from the moving plate.

[0014] Preferably, both ends of the bottom of the placement plate and the rotating plate are provided with guide grooves. The end of the telescopic rod near the fixed plate is slidably installed inside the guide groove at the bottom of the placement plate, and the end of the telescopic rod near the moving plate is movably installed inside the guide groove at the bottom of the rotating plate.

[0015] Preferably, the opposite surfaces of the placement plate and the rotating plate are provided with connecting grooves, and a connecting plate is installed between the placement plate and the rotating plate. The two sides of the connecting plate are respectively rotatably installed on the inner walls of the two connecting grooves. Support legs are installed at both ends of the bottom of the fixed plate and the moving plate, and universal wheels are rotatably installed on the bottom side of the support legs located on the moving plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The testing equipment in this invention can be folded for easy storage by staff. Several conveyor cylinders for yarn testing can be installed simultaneously, allowing for the simultaneous testing of large quantities of yarns of different specifications, thus improving testing efficiency. During yarn conveying, friction occurs at the edges of the first conveying hole. An electrostatic generator inside the conveyor cylinder releases static electricity from the yarn surface. After friction, snagging or fiber migration occurs on the yarn surface, resulting in a large amount of fuzz on the fabric surface. This design effectively prevents friction on the yarn and... The toughness and strength are tested. When the static electricity released by the electrostatic generator comes into contact with the rubbed yarn, the fuzz on the surface of the yarn will stand up. During use, the antistatic properties of the yarn can be tested. When the yarn is fed to the side of the scanner, the scanner can scan the yarn. During use, the anti-friction effect of the yarn can be tested according to the amount and degree of fuzz on the surface of the yarn. The heating plate can heat the yarn, which facilitates the testing of the yarn's thermal strength. At the same time, when the heating plate tests the yarn, when the thermal strength of the yarn is low, the fuzz on the surface of the rubbed yarn will curl up and deform.

[0018] 2. In this invention, when the conveyor cylinder is used to detect the spun yarn, the heat-absorbing plate located on the outer wall of the conveyor cylinder can absorb the light shining on the surface of the conveyor cylinder from the outside. The heat-absorbing plate is a solar panel. When in use, it uses the photoelectric effect to convert solar energy into electrical energy, and the converted electrical energy is electrically connected to the electrostatic generator, scanner, heating plate and several electric rotating shafts. When the detection equipment is in use, it converts solar energy into electrical energy and consumes the converted electrical energy when detecting the spun yarn. When in use, the detection equipment can be used for electrical energy conversion and can simultaneously perform multi-faceted detection on a large amount of spun yarn.

[0019] 3. In this invention, after the yarn testing is completed, the worker can disassemble the conveyor cylinder and place it inside the placement slot at the top of the placement plate. Simultaneously, the rotating plate is rotated to the top of the placement plate. During use, the placement plate and rotating plate clamp and protect the conveyor cylinder. Pushing the placement plate and rotating plate until the rotating plate abuts against the support plate, the telescopic rod pulls the moving plate, causing it to cooperate with the fixed plate and support plate to clamp the placement plate and rotating plate. During use, the placement plate, rotating plate, and moving plate retract towards the fixed plate, while the fixed plate folds. The conveyor cylinder facilitates the storage and handling of testing equipment by staff. It not only transports the yarn but also provides good protection for the yarn during transport. Furthermore, the conveyor cylinder can simultaneously perform tension testing, heat resistance testing, friction strength testing, and antistatic testing on the yarn, making the yarn testing more comprehensive. At the same time, the scanner can scan the yarn diameter while scanning the surface fuzz, preventing discrepancies in diameter at different locations. It also prevents damage or imminent breakage of the yarn surface during abrasion testing due to poor abrasion resistance.

[0020] 4. In this invention, the operator can adjust the distance between the fixed plate and the moving plate according to the usage situation, and install and place the conveyor cylinder according to the number of yarns to be detected. The conveyor cylinder consists of two mutually rotating and connected arc-shaped plates. When installing the yarn, the conveyor cylinder can be opened, and the yarn can be limited and supported by the baffle and the limiting plate. At the same time, the baffle and the limiting plate can divide the interior of the conveyor cylinder into several areas, so that several areas can be detected in different directions. The beneficial aspects cooperate with each other, such as releasing static electricity on the yarn, causing the fuzz on the surface of the yarn to stand up after friction, which makes it easier for the scanner to scan the yarn and its surface fuzz, and also makes it easier for the heating plate to heat and detect the fuzz on the surface of the yarn. However, the baffle and the limiting plate can also isolate the different areas from each other, preventing the heat dissipated by the heating plate from having a significant impact on the detection plate.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Reference Figure 1-8An online quality inspection mechanism for aggregated yarn includes a fixed plate 1, a support plate 2 rotatably mounted on the top of the fixed plate 1, telescopic rods 24 mounted on both ends of one side of the support plate 2, a placement plate 3 slidably mounted on the top end of the telescopic rods 24 near the fixed plate 1, a rotating plate 4 rotatably mounted on the side of the placement plate 3 away from the fixed plate 1, and a movable plate 5 mounted on the end of the telescopic rods 24 away from the fixed plate 1. Placement slots 8 are provided along the length direction on the top of both the placement plate 3 and the rotating plate 4. Several conveying cylinders 6 are obliquely mounted on the top side of the support plate 2 near the movable plate 5. Each conveying cylinder 6 is composed of two mutually rotatably connected arc-shaped plates, and heat-absorbing plates 7 are mounted on the outer walls of the arc-shaped plates.

[0033] As a technical optimization of the present invention, a plurality of first limiting grooves 16 are provided on the top of the support plate 2 near the corner of the moving plate 5, and a plurality of second limiting grooves 19 are provided on the inner wall of the top placement groove 8 of the rotating plate 4 away from the fixed plate 1. The bottom end of the conveying cylinder 6 is located inside the second limiting groove 19, and the top end of the conveying cylinder 6 is located inside the first limiting groove 16. A first conveying hole 20 is provided on the inner wall of the second limiting groove 19 away from the fixed plate 1. In use, the first limiting groove 16 and the second limiting groove 19 respectively support and limit the position of the two ends of the conveying cylinder 6.

[0034] As a technical optimization of the present invention, a plurality of baffles 28 are installed on the inner wall of the conveying cylinder 6. A limiting plate 29 is rotatably installed on the side of the baffle 28. A limiting hole 30 is opened at one end of the side of both the limiting plate 29 and the baffle 28. A guide rod 37 is installed at the top of the opposite face of two adjacent baffles 28. A movable sleeve 38 is slidably installed on the outer wall of both ends of the guide rod 37. A connecting rod 40 is rotatably installed at the bottom end of the movable sleeve 38. A spring 39 is installed on the outer wall of the guide rod 37 between the baffle 28 and the movable sleeve 38. When the yarn is conveyed through the inside of the conveying cylinder 6, the tension detection plate 34 presses down on the yarn through the elasticity of the spring 39, so that the yarn between the two baffles 28 at both ends of the tension detection plate 34 is squeezed by the tension detection plate 34 and becomes arc-shaped. When the yarn is too loose during conveying, the yarn position below the tension detection plate 34 The friction between the two ends of the device and the limiting holes 30 on the baffle 28 will increase, resulting in a slower yarn feeding. The operator can pull the yarn by increasing the rotation speed of the take-up wheel 13, which reduces the deformation of the yarn below the tension detection plate 34 caused by the elastic compression of the spring 39, and at the same time reduces the friction between the yarn and the limiting holes 30. The looser the yarn is during feeding, the less pressure it exerts on the tension detection plate 34. The closer the yarn is to a taut state during feeding, the greater the pressure it exerts on the tension detection plate 34. The tension detection plate 34 can monitor the pressure of the yarn and is electrically connected to an external display. The operator can understand the tension of the yarn through the display results and adjust the tightness of the yarn during feeding by rotating the take-up wheel 13.

[0035] As a technical optimization of the present invention, a tension detection plate 34 is installed inside the conveying cylinder 6 below the guide rod 37. The ends of the two connecting rods 40 away from the moving sleeve 38 are respectively rotatably connected to the two ends of the tension detection plate 34. An arc-shaped groove 41 is opened at the bottom of the tension detection plate 34 along the length direction. When the yarn is conveyed, it is located inside the arc-shaped groove 41. The arc-shaped groove 41 can play a good guiding and position limiting role for the conveyed yarn.

[0036] As a technical optimization of the present invention, a heating plate 31 is installed on the inner wall of the conveying cylinder 6 between two adjacent baffles 28. The heating plate 31 is located on the side of the guide rod 37 near the support plate 2. A scanner 32 is installed on the inner wall of the conveying cylinder 6 on the side of the guide rod 37 near the moving plate 5. An electrostatic generator 33 is installed on the inner wall of the conveying cylinder 6 on the side of the scanner 32 near the moving plate 5. The heating plate 31 can heat the conveyed yarn during use and can test the heat resistance of the yarn during use.

[0037] As a technical optimization of the present invention, one of the arc-shaped plates used to form the conveying cylinder 6 has a second slot 35 at its top end, and a second slot 36 is installed on the side of the top end of the other arc-shaped plate. The top of the placement plate 3 has a fixing groove 9 along its length. The inner wall of the fixing groove 9 near the fixing plate 1 has a plurality of second conveying holes 27 that match the first conveying hole 20. In use, the conveying cylinder 6 is composed of two arc-shaped plates, and the bottom ends of the two arc-shaped plates are rotatably connected to each other. When the operator needs to install and place the conveyed yarn, the operator can open the arc-shaped plates. When the yarn is conveyed and tested, the two arc-shaped plates abut against each other, so that the two arc-shaped plates form a cylindrical conveying cylinder 6.

[0038] As a technical optimization of the present invention, the support plate 2 is provided with an inner cavity 14, and a plurality of feed holes 15 are provided on the top of the inner cavity 14. The top of the feed holes 15 is located on the side of the first limiting groove 16, and a through hole 25 is provided on the bottom of the inner cavity 14 near the moving plate 5. After the yarn is tested, it can enter the interior of the inner cavity 14 through the feed holes 15, which makes it convenient for the staff to collect the tested yarn.

[0039] As a technical optimization of the present invention, a groove 11 is provided on the side of the support plate 2 away from the moving plate 5, and the bottom end of the through hole 25 is connected to the groove 11. Several electric rotating shafts 12 are rotatably installed on the inner wall of the groove 11, and a winding wheel 13 is installed on the outer wall of the electric rotating shaft 12. A first slot 22 is provided at the top end of the fixed plate 1 near the support plate 2, and a first locking block 23 is installed at the bottom end of the support plate 2 away from the moving plate 5. In use, each conveying cylinder 6 corresponds to each winding wheel 13, and the winding wheel 13 winds up the detected yarn.

[0040] As a technical optimization of the present invention, guide grooves 26 are provided at both ends of the bottom of the placement plate 3 and the rotating plate 4. The end of the telescopic rod 24 near the fixed plate 1 is slidably installed inside the guide groove 26 at the bottom of the placement plate 3, and the end of the telescopic rod 24 near the moving plate 5 is movably installed inside the guide groove 26 at the bottom of the rotating plate 4. The telescopic rod 24 can adjust the distance between the fixed plate 1 and the moving plate 5 during use, making it convenient for staff to fold and store the testing equipment at any time.

[0041] As a technical optimization of the present invention, the opposite surfaces of the placement plate 3 and the rotating plate 4 are provided with connecting grooves 17, and a connecting plate 18 is installed between the placement plate 3 and the rotating plate 4. The two sides of the connecting plate 18 are respectively rotatably installed on the inner walls of the two connecting grooves 17. Support legs 10 are installed at both ends of the bottom of the fixed plate 1 and the moving plate 5. Universal wheels 21 are rotatably installed on the bottom side of the support legs 10 located on the moving plate 5. After the yarn spinning test is completed, the operator can place the conveying cylinder 6 inside the placement groove 8 and fold the rotating plate 4 so that the tops of the placement plate 3 and the rotating plate 4 abut against each other, and clamp and protect the conveying cylinder 6.

[0042] In use, the operator rotates the support plate 2, causing it to be vertically mounted on top of the fixed plate 1. Simultaneously, the operator moves the movable plate 5 using the telescopic rod 24, adjusting the distance between the fixed plate 1 and the movable plate 5 as needed. The operator then rotates the rotating plate 4, placing the placement plate 3 and the rotating plate 4 flat on top of the telescopic rod 24, with the end of the rotating plate 4 away from the placement plate 3 abutting against the movable plate 5. The operator installs and places the conveyor cylinder 6 according to the detected quantity of spun yarn. During use, the operator places the conveyor cylinder 6 above the placement plate 3, with the top end of the conveyor cylinder 6 located inside the first limiting groove 16 at the top of the support plate 2, and the bottom end of the conveyor cylinder 6 located inside the second limiting groove 19 on the inner wall of the placement groove 8 at the top of the rotating plate 4.

[0043] The conveyor cylinder 6 consists of two arc-shaped plates, with their bottom ends rotatably connected. During use, the operator opens one of the arc-shaped plates. The operator places one end of the yarn to be tested inside the fixed groove 9 at the top of the moving plate 5, and then passes the yarn through the second conveying hole 27 and the first conveying hole 20 into the second limiting groove 19. The yarn also passes through several baffles 28 and limiting holes 30 on the limiting plate 29 inside the conveyor cylinder 6. After passing through the conveyor cylinder 6, one end of the yarn passes through the feed hole 15, the inner cavity 14, and the through hole 25, and is wound onto the take-up roller 13. During use, several take-up rollers 13 correspond to several conveyor cylinders 6, ensuring that the yarn being tested inside a single conveyor cylinder 6 is wound onto the corresponding take-up roller 13. This facilitates marking the tested yarn and removing any defective yarn.

[0044] After the staff has placed the yarn to be tested, they rotate the limiting plate 29 so that it rotates to the side of the baffle 28. The limiting holes 30 on the baffle 28 and the limiting plate 29 are offset from each other, but the limiting holes 30 on the baffle 28 and the limiting plate 29 still overlap near the center line of the conveying cylinder 6. The position of the limiting holes 30 on the baffle 28 and the limiting plate 29 at the center line of the conveying cylinder 6 can limit the position of the yarn being conveyed inside the conveying cylinder 6, and at the same time support the yarn, making the yarn more stable when conveyed inside the conveying cylinder 6, preventing the yarn from shaking during conveying, which would prevent the electrostatic generator 33, scanner 32 and tension detection plate 34 from accurately detecting the yarn.

[0045] When in use, the electric rotating shaft 12 drives the winding wheel 13 to rotate, and the electric rotating shaft 12 pulls the conveyed yarn to wind up, while the external unwinding wheel feeds the yarn into the fixed groove 9. During the conveying and testing of the spun yarn, the first conveying hole 20 and the feed hole 15 limit the position of the spun yarn at both ends of the conveying cylinder 6, while preventing the spun yarn near the first conveying hole 20 and the feed hole 15 from pulling the conveying cylinder 6 and causing displacement during use. At the same time, the edges at both ends of the first conveying hole 20 rub against the spun yarn during use. After the rubbed spun yarn enters the interior of the conveying cylinder 6, the electrostatic generator 33 located inside the conveying cylinder 6 can release static electricity on the surface of the spun yarn. The rubbed spun yarn surface will have snagging or fibers migrating to the surface, resulting in a large amount of fluff on the fabric surface. During use, the anti-friction and toughness strength of the spun yarn can be tested. When the static electricity released by the electrostatic generator 33 comes into contact with the rubbed spun yarn, the fluff on the surface of the spun yarn will stand up. During use, the anti-static effect of the spun yarn can be tested. When the spun yarn is conveyed to the side of the scanner 32, the scanner 32 can scan the spun yarn. During use, the anti-friction effect of the spun yarn can be tested according to the amount and degree of fluff on the surface of the spun yarn.

[0046] During use, the bottom end of the tension detection plate 34 located inside the conveying cylinder 6 abuts against the yarn, and the conveyed yarn is located inside the arc groove 41 at the bottom end of the tension detection plate 34. During use, the spring 39 can push the moving sleeve 38 and the connecting rod 40 through its own elasticity, so that the tension detection plate 34 squeezes the conveyed yarn, so that the yarn is always in a taut state during conveying, which facilitates the toughness test of the yarn. The yarn between the two baffles 28 at both ends of the tension detection plate 34 undergoes arc-shaped deformation due to the compression of the tension detection plate 34. When the yarn is too loose during transport, the tension detection plate 34 will push the yarn towards the inner wall of the conveying cylinder 6, keeping the yarn taut. The friction between the ends of the yarn below the tension detection plate 34 and the limiting holes 30 on the baffles 28 will increase, resulting in slower yarn transport. The operator can then increase the speed of the take-up roller 13 to pull the yarn during transport, causing the yarn below the tension detection plate 34 to deform due to the elastic compression of the spring 39. The arc angle decreases, reducing friction between the yarn and the limiting hole 30. During use, the tension detection plate 34 detects the tension of the yarn by measuring the degree of compression, facilitating adjustments to the yarn's tension during transport. When the spring 39 is compressed, the shorter the distance between its two ends, the greater the force with which the yarn pushes the tension detection plate 34. This also increases the tension at the ends of the yarn below the tension detection plate 34. The tension detection plate 34 detects the force applied, allowing operators to assess the yarn's tension. When the yarn is transported to the side of the heating plate 31, the heating plate 31 heats it, facilitating the detection of its heat intensity. When the heating plate 31 detects low heat intensity, the fuzz on the surface of the yarn, subjected to friction, will curl and deform. When the yarn is heated during the tensioning and conveying process, because the fibers in the yarn are relatively intact and it is in a tensile conveying state, the yarn will only be slightly stretched and will not undergo any other significant deformation when heated. This makes it inconvenient for workers to observe the heat intensity of the yarn. However, after the yarn is rubbed, the snagging and fuzz on its surface will deform and curl when heated, and workers can test and understand the heat intensity of the yarn by observing the degree of curling of the surface fuzz.

[0047] When the conveyor cylinder 6 is used to test the spun yarn, the heat-absorbing plate 7 located on the outer wall of the conveyor cylinder 6 can absorb the light shining on the surface of the conveyor cylinder 6. The heat-absorbing plate 7 is a solar panel. When in use, it uses the photoelectric effect to convert solar energy into electrical energy, and the converted electrical energy is electrically connected to the electrostatic generator 33, the scanner 32, the heating plate 31 and several electric rotating shafts 12. When the testing equipment is in use, it converts solar energy into electrical energy and consumes the converted electrical energy when testing the spun yarn. When in use, the testing equipment can be used for electrical energy conversion and can simultaneously perform multi-faceted testing on a large amount of spun yarn.

[0048] After the yarn is tested, the staff can disassemble the conveyor cylinder 6 and place it inside the placement groove 8 on top of the placement plate 3. The staff rotates the support plate 2 to the top of the fixed plate 1, and at the same time rotates the rotating plate 4 to the top of the placement plate 3. In use, the placement plate 3 and the rotating plate 4 can clamp and protect the conveyor cylinder 6. At the same time, push the placement plate 3 and the rotating plate 4 until the rotating plate 4 abuts against the support plate 2. The telescopic rod 24 pulls the moving plate 5, so that the moving plate 5 cooperates with the fixed plate 1 and the support plate 2 to clamp the placement plate 3 and the rotating plate 4. In use, the placement plate 3, the rotating plate 4 and the moving plate 5 retract towards the fixed plate 1, and the fixed plate 1 is folded, which makes it convenient for the staff to store the testing equipment.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
