Description

Technical Field

[0001] This invention relates to the field of spandex fiber winding equipment technology, specifically to an automatic winding and knotting device for spandex fiber production and a knotting inspection method. Background Technology

[0002] After being coated, spandex fibers need to be wound onto a spool. During the winding process, the yarn is continuously wound back and forth from one end of the spool to the other, thus winding it evenly onto the spool. Traditional winding methods are prone to the yarn becoming tangled and knotted at both ends of the spool. To avoid this situation, Chinese Patent No. CN109205390A discloses a spandex yarn knotting treatment device, which prevents the yarn from detaching from the spool and knotting by setting limiting plates at both ends of the spool during the yarn winding process.

[0003] However, existing equipment for winding spandex yarn still faces certain technical problems, as follows:

[0004] 1. In the existing technology, the equipment for winding spandex yarn is only set up with one support spool station. Regardless of whether the spool is fixed by flange, clamping structure, or sleeve, after the spool is fully loaded, the fully loaded spool must be removed first, and then an empty spool must be installed before the winding work can continue. The time interval is long and the winding work is stopped for a long time, which greatly affects the production efficiency.

[0005] 2. During the winding process of spandex yarn, due to equipment, environment, or the quality of the yarn itself, short fibers may scatter and fly into the air to varying degrees. Existing spandex yarn winding equipment has good solutions to deal with this, but the limited amount of scattering has a significant impact on the health of workers, the operating status of equipment, and the factory environment.

[0006] Therefore, it is necessary to provide an automatic winding and knotting device and a knotting inspection method for spandex fiber production to solve the above-mentioned technical problems. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To solve the above-mentioned technical problems, the present invention provides an automatic winding and knotting device for spandex fiber production and a knotting inspection method.

The connecting assembly is used to connect the output end of the rotating assembly and one rotating shaft close to the rotating assembly.

[0012] Preferably, the connecting assembly includes a connecting plate fixed to one end of a rotating shaft near the rotating assembly. The connecting plate has three connecting slots spaced at equal angles. A turntable is fixed to the output end of the rotating assembly. Three pins are slidably connected to the turntable at equal angles through sliding holes. The three pins are respectively inserted into the three connecting slots on the turntable facing the rotating assembly. Three springs are sleeved at equal angles on the side of the turntable near the rotating assembly. One end of each spring is fixed to the outer wall of the turntable, and the other end is fixed to the outer wall of the pin.

[0013] Preferably, the outer wall of the winding frame is symmetrically fixed with first linear slide rails, the moving ends of the two first linear slide rails are fixed with moving plates, the top of the moving plates is fixed with second slide rails, the outer wall of the second slide rails is slidably connected with second sliders, and the moving frame is fixed to the top of the second sliders.

[0014] Preferably, the moving mechanism includes a horizontal plate fixed to the top surface of the second slider, a drive shaft rotatably mounted on one end of the horizontal plate near the rotating assembly, a drive plate fixed to the top of the winding frame, a drive groove formed on the drive plate, the drive shaft inserted into the drive groove, the drive plate located below the horizontal plate, a support rod rotatably mounted on the winding frame, a drive frame fixed to the outer wall of the support rod, the drive frame located below the drive plate, the lower end of the drive shaft passing through the drive groove and inserted into the inner wall of the drive frame, and a flipping mechanism for driving the drive frame to rotate fixed on the winding frame.

[0015] Preferably, the flipping mechanism includes a connecting shaft rotatably mounted on the winding frame, and a first electric push rod is fixed to the outer wall of the connecting shaft. The extended end of the first electric push rod is rotatably connected to the drive frame through a pin.

[0016] Preferably, a sleeve is fixed on the side of the clamping cone away from the limiting cone. The sleeve is inserted into the end of the rotating shaft. A bolt is threadedly connected to the side wall of the sleeve through a threaded hole. The end of the bolt is pressed against the outer wall of the rotating shaft.

[0017] Preferably, the support assembly includes an upright plate fixed to the top of the winding frame on the side away from the rotating assembly. A protective plate is slidably mounted on the outer wall of the upright plate via a second linear slide rail. The middle part of the protective plate is hollow. Limit forks are symmetrically fixed at the bottom of the protective plate. A second electric push rod is fixed on the outer wall of the upright plate, and the extended end of the second electric push rod is fixed to the protective plate.

[0018] Preferably, the adsorption assembly includes an air pump fixed to the outer wall of the winding frame, an air inlet pipe fixed to the air pump, a dust collection hood fixed to the end of the air inlet pipe away from the air pump, the dust collection hood facing the support assembly, a filter screen fixed to the side of the dust collection hood near the support assembly, a connecting frame fixed to the side of the second slide rail near the filter screen, and a brush plate fixed to the side of the connecting frame near the filter screen, the brush plate cooperating with the filter screen.

[0019] This invention provides a knot inspection method, employing an automatic winding and knotting device for spandex fiber production, specifically comprising the following parts:

[0020] A1. After being wrapped by the wrapping production equipment, the spandex yarn passes through the middle of the protective plate and is fixed to the outer wall of the spool.

[0021] A2. By driving the rotating component, the support component causes the bobbin to rotate and wind the yarn.

[0022] A3. During the winding process, the limiting fork is inserted at both ends of the bobbin to prevent the yarn from becoming tangled at both ends of the bobbin, thereby avoiding knots;

[0023] A4. After winding, the yarn spool is unloaded, and both ends of the spool are manually inspected to check whether the yarn at both ends of the spool is loose or knotted.

[0024] (III) Beneficial Effects

[0025] This invention provides an automatic winding and knotting device and a knotting inspection method for spandex fiber production. Compared with the prior art, it has the following advantages:

[0026] 1. When a bobbin is mounted on a support component directly opposite the rotating component and driven to rotate for the winding of spandex yarn, the side support component can be used to disassemble the fully loaded bobbin that has been wound in the previous operation and to install the empty bobbin needed for the next operation. Thus, when the winding of the currently being wound bobbin is completed, it is only necessary to drive the moving mechanism to move the moving frame to switch the positions of the two bobbins, and then the winding of spandex yarn can continue. Compared with the existing technology, this greatly reduces the equipment downtime and improves the winding efficiency.

[0027] 2. By setting up an adsorption component, short fibers scattered in the air during yarn winding can be automatically adsorbed, preventing short fibers from scattering and causing harm to the equipment and workers' health. At the same time, the movement of the mobile frame can automatically clean the filter screen, ensuring that it always has a strong adsorption force to adsorb short fibers. Frequent manual operation is not required, saving manpower. Moreover, no additional power equipment is needed, as the power of the moving frame is used to complete the operation, reducing equipment operation and maintenance costs as well as equipment manufacturing costs.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1, please refer to Figures 1 to 12The present invention provides a technical solution: an automatic winding and knotting device for spandex fiber production, including a winding frame 1, a movable frame 2 installed on the top of the winding frame 1, first linear slide rails 8 symmetrically fixed on the outer wall of the winding frame 1, movable plates 9 fixed to the moving ends of the two first linear slide rails 8, a second slide rail 10 fixed on the top of the movable plates 9, a second slider 11 slidably connected to the outer wall of the second slide rail 10, and the movable frame 2 fixed on the top of the second slider 11, so that the movable frame 2 can move linearly in the horizontal and vertical directions on the winding frame 1;

[0043] Two sets of support components 3 for supporting the bobbin 100 are symmetrically installed on the top of the movable frame 2. A rotating component 4 for driving the bobbin 100 to rotate is installed on the winding frame 1. The input end of one of the support components 3 facing the rotating component 4 is detachably connected to the output end of the rotating component 4. A moving mechanism 5 for driving the movable frame 2 to move, so that the two support components 3 are alternately connected to the rotating component 4 is fixed on the top of the winding frame 1. A support component 6 for preventing knotting is fixed on the top of the winding frame 1 during the winding of the yarn by the bobbin 100. An adsorption component 7 for adsorbing the short fibers generated by the winding yarn is fixed on the winding frame 1.

[0044] When a support component 3 facing the rotating component 4 is driven by the rotating component 4 to rotate the bobbin 100 mounted on it for the winding of spandex yarn, an empty bobbin 100 can be installed on the support component 3 in the side position. Wait for the bobbin 100 to be fully loaded. After it is fully loaded, drive the moving mechanism 5 to move the moving frame 2, which in turn moves the two support components 3. This moves the fully loaded bobbin 100 to one side, while the empty bobbin 100 moves to the position facing the rotating component 4. The input end of the support component 3 below the empty bobbin 100 is connected to the output end of the rotating component 4. Then, the winding work continues to be carried out by the rotating component 4.

[0045] This greatly reduces the downtime of the equipment for loading and unloading the yarn spool 100, and greatly improves the yarn winding efficiency.

[0046] Furthermore, during the yarn winding process, the adsorption component 7 can adsorb the fine fibers generated during winding, preventing them from drifting into the air and affecting the equipment, workers' health, and the factory environment.

[0047] The support assembly 3 includes support blocks 31 symmetrically fixed on the movable frame 2. The upper end of the support block 31 is rotatably connected to a rotating shaft 32 via a bearing. A clamping cone 33 is sleeved and fixed on the inner side of one rotating shaft 32 away from the rotating assembly 4. A limiting cone 34 is fixed on the inner side of one rotating shaft 32 close to the rotating assembly 4. When the spool 100 is installed, it is clamped against the limiting cone 34 by the clamping cone 33. A connecting assembly 35 is fixed at the end of one rotating shaft 32 close to the rotating assembly 4 away from the limiting cone 34. The connecting assembly 35 is used to connect the output end of the rotating assembly 4 and one rotating shaft 32 close to the rotating assembly 4. A sleeve 331 is fixed on the side of the clamping cone 33 away from the limiting cone 34. The sleeve 331 is inserted into the end of the rotating shaft 32. A bolt 332 is threadedly connected to the side wall of the sleeve 331 through a threaded hole. The end of the bolt 332 is clamped against the outer wall of the rotating shaft 32.

[0048] When installing the spool 100, first rotate the bolt 332 to separate the bolt 332 from the outer wall of the rotating shaft 32. Then push the clamping cone 33 away from the limiting cone 34 to increase the distance between the limiting cone 34 and the clamping cone 33. Then insert the spool 100 between the two. Then push the clamping cone 33 towards the side closer to the limiting cone 34 until both the clamping cone 33 and the limiting cone 34 are clamped against both ends of the spool 100. Then rotate the bolt 332 to fix the sleeve 331 on the rotating shaft 32, thus completing the installation of the spool 100.

[0049] The clamping cone 33 and the limiting cone 34 are made of hard rubber material, which ensures strength and can also improve the friction between them and the outer wall of the spool 100.

[0050] The moving mechanism 5 includes a horizontal plate 51 fixed on the top surface of the second slider 11. A drive shaft 52 is rotatably mounted on one end of the horizontal plate 51 near the rotating assembly 4. A drive plate 53 is fixed on the top of the winding frame 1. A drive groove 54 is provided on the drive plate 53. The drive shaft 52 is inserted into the drive groove 54. The drive plate 53 is located below the horizontal plate 51. A support rod 55 is rotatably mounted on the winding frame 1. A drive frame 56 is fixed on the outer wall of the support rod 55. The drive frame 56 is located below the drive plate 53. The lower end of the drive shaft 52 passes through the drive groove 54 and is inserted into the inner wall of the drive frame 56. A flipping mechanism 57 for driving the drive frame 56 to rotate is fixed on the winding frame 1.

[0051] The flipping mechanism 57 drives the drive frame 56 to rotate. The drive frame 56, in conjunction with the drive groove 54, causes the drive shaft 52 to move along the inner wall of the drive groove 54. The drive shaft 52 first moves linearly along one end of the drive groove 54, causing the movable frame 2, the second slider 11, the second slide rail 10, and the movable plate 9 to slide along the length of the first linear slide rail 8 on the winding frame 1 away from the rotating component 4. This causes the input end of a support component 3 facing the rotating component 4 to separate from the output end of the rotating component 4. Subsequently, the drive shaft 52 enters the middle of the drive groove 54. Then, under the action of the drive groove 54 and the drive frame 56, the drive shaft 52 drives the movable frame 2 and the second slider 11 on the second slide rail. The slide 10 slides along the outer wall of the second slide rail 10, thereby moving a support component 3 facing the rotating component 4 to one side. The support component 3 originally on one side moves to the position facing the rotating component 4. Then the drive shaft 52 enters the other end of the drive groove 54. Then, driven by the continued rotation of the drive frame 56, the drive shaft 52 moves linearly in the other end of the drive groove 54, driving the moving frame 2, the second slider 11, the second slide rail 10 and the moving plate 9 to slide along the length direction of the first linear slide rail 8 towards the side closer to the rotating component 4, until the input end of the support component 3 facing the rotating component 4 is connected to the output end of the rotating component 4. Then the spandex yarn winding work can continue.

[0052] The simultaneous unloading of fully loaded bobbins 100 and loading of empty bobbins 100 greatly reduces the downtime of the winding process and significantly improves the winding efficiency of spandex yarn.

[0053] The flipping mechanism 57 includes a connecting shaft 571 rotatably mounted on the winding frame 1. A first electric push rod 572 is fixed on the outer wall of the connecting shaft 571. The extended end of the first electric push rod 572 is rotatably connected to the drive frame 56 through a shaft pin. The operation of the flipping mechanism 57 can be completed by driving the first electric push rod 572 to extend or retract.

[0054] The rotating assembly 4 includes a motor 41 fixed to the top of the winding frame 1. The top of the winding frame 1 is located below the motor 41 and is rotatably connected to an output shaft 42 via a bearing. Pulleys 43 are fixed on the output shaft 42 and the output end of the motor 41. A belt 44 is connected between the two pulleys 43.

[0055] The rotating component 4 operates by driving the motor 41 to rotate, which in turn drives the pulley 43 to rotate, thereby causing the output shaft 42 to rotate via the belt 44.

[0056] The connecting assembly 35 includes a connecting plate 351 fixed to the end of a rotating shaft 32 near the rotating assembly 4. The connecting plate 351 has three connecting slots 352 spaced at equal angles. One end of the output rotating shaft 42 is fixed to a turntable 353. Three inserts 354 are slidably connected to the turntable 353 at equal angles through sliding holes. The three inserts 354 are respectively inserted into the three connecting slots 352 on the turntable 353 facing the rotating assembly 4. Three springs 355 are sleeved at equal angles on the side of the turntable 353 near the rotating assembly 4. One end of the spring 355 is fixed to the outer wall of the turntable 353 and the other end is fixed to the outer wall of the insert 354.

[0057] When the moving mechanism 5 drives the moving frame 2 to move away from the rotating component 4 along the length of the first linear slide rail 8, the connecting plate 351 separates from the insert post 354. When the unloaded bobbin 100 is installed on the support component 3 and moved closer to the rotating component 4 by the moving mechanism 5, if the three connecting slots 352 on the connecting plate 351 of the support component 3 are aligned with the three insert posts 354, the insert posts 354 are inserted into the connecting slots 352 as the moving frame 2 moves into place. Subsequently, the rotating component 4 drives the turntable 353 to rotate, which in turn drives the connecting plate 351 to rotate, causing the bobbin 100 to rotate and perform the winding operation. If the three connecting slots 352 on the connecting plate 351 of the support component 3 are not aligned with the insert post 354, the connecting plate 351 will push the insert post 354 during the movement of the moving frame 2, causing the insert post 354 to slide and stretch the spring 355 until the moving frame 2 is in place. Then, the rotating component 4 will drive the turntable 353 to rotate. As the turntable 353 rotates, when the insert post 354 is aligned with the connecting slot 352, the spring 355 will push the insert post 354 into the connecting slot 352 with its rebound force. Then, the turntable 353 will continue to rotate, which will drive the bobbin 100 to rotate for winding yarn.

[0058] The support assembly 6 includes a vertical plate 61 fixed on the top of the winding frame 1 away from the rotating assembly 4. A protective plate 62 is slidably installed on the outer wall of the vertical plate 61 via a second linear slide rail 65. The middle part of the protective plate 62 is hollow. Limiting forks 63 are symmetrically fixed at the bottom of the protective plate 62. A second electric push rod 64 is fixed on the outer wall of the vertical plate 61. The extended end of the second electric push rod 64 is fixed to the protective plate 62.

[0059] When the support component 3 needs to move to switch positions, the second electric push rod 64 is extended by driving it to raise the limit fork 63, so that the limit fork 63 can avoid the movement. After the two support components 3 have finished moving and switching positions, the second electric push rod 64 retracts, so that the limit fork 63 is inserted again at both ends of a bobbin 100 facing the rotating component 4, thus preventing the yarn from separating and knotting with the bobbin 100 during the winding process.

[0060] The adsorption assembly 7 includes an air pump 71 fixed on the outer wall of the winding frame 1. An air inlet pipe 72 is fixed to the air inlet end of the air pump 71. A dust collection hood 73 is fixed to the end of the air inlet pipe 72 away from the air pump 71. The dust collection hood 73 faces the support assembly 3. A filter screen 74 is fixed to the side of the dust collection hood 73 near the support assembly 3. A connecting frame 75 is fixed to the side of the second slide rail 10 near the filter screen 74. A brush plate 76 is fixed to the side of the connecting frame 75 near the filter screen 74. The brush plate 76 cooperates with the filter screen 74.

[0061] During the winding process, the air pump 71 is driven to bring air containing short fibers into the dust collection hood 73. The short fibers are then filtered onto the filter screen 74. This adsorption of short fibers prevents them from scattering and affecting the health of workers, equipment, and the factory environment.

[0062] Each time the position of the support component 3 is switched, the moving frame 2 moves along the length of the first linear slide rail 8, causing the connecting frame 75 and the brush plate 76 to move together. The brush plate 76 pushes the fibers attached to the middle of the filter screen 74 to both sides of the filter screen 74, preventing the accumulated fibers from clogging the middle of the filter screen 74 and affecting the air passage rate, ensuring that air can always be effectively drawn to perform the short fiber adsorption work until a certain period of time has accumulated, after which the short fibers accumulated on both sides of the filter screen 74 are manually cleaned.

[0063] In summary, this invention enables the disassembly of a fully loaded bobbin 100 and the installation of an empty bobbin 100 during the spandex yarn winding process. Once the currently winding bobbin 100 is fully loaded, the two support components 3 can be moved directly to unload the fully loaded bobbin 100 and load the empty bobbin 100, allowing the spandex yarn winding process to continue. This significantly reduces the downtime of spandex yarn winding, improves production efficiency, and simultaneously absorbs and traps short fibers that fall during the winding process, preventing them from scattering in all directions.

[0064] Example 2: This example provides a knot inspection method using an automatic winding and knotting device for spandex fiber production, specifically including the following parts:

[0065] A1. After being wrapped by the wrapping production equipment, the spandex yarn passes through the middle of the protective plate 62 and is fixed on the outer wall of the yarn drum 100.

[0066] A2. By driving the rotating component 4, the support component 3 drives the bobbin 100 to rotate and wind the yarn.

[0067] A3. During the winding process, the limiting fork 63 is inserted at both ends of the bobbin 100 to prevent the yarn from becoming tangled at both ends of the bobbin 100, thereby preventing knotting.

[0068] A4. After winding is completed, the yarn spool 100 is unloaded. The two ends of the yarn spool 100 are manually inspected to observe whether there is any loose or knotted yarn at the two ends of the yarn spool 100.
