Description

TECHNICAL FIELD

[0001] The application relates to the technical field of crane structures, in particular to high-elasticity semi-dull POY polyester fiber spinning equipment and a process. BACKGROUND

[0002] Polyester fibers have high modulus, high strength and high elasticity, which makes them very durable and not easy to deform. In addition, polyester fibers have good shape retention and heat resistance, and are suitable for use in various environments. Polyester fibers also have excellent wrinkle resistance and non-iron properties, which make them very popular in making outdoor products such as coats and bags. However, traditional polyester filament production equipment often has problems such as poor fiber uniformity, uneven yarn, and insufficient elasticity when producing cashmere-like or soft-like fibers, limiting its application in the high-end fabric market.

[0003] The existing spinning equipment is wound on the winding rod, and no device is provided to adjust the yarn to make it evenly wound on the winding rod (generally, automatic adjustment is achieved by pressing between yarns, which can easily cause uneven distribution of yarns and concentrated winding on one part). Although a small number of related uniform devices are provided, such as the setting of multiple gap distributed limit groove plates to ensure uniform winding, the stability of uniform winding is not good.

[0004] Therefore, we propose a high-elasticity semi-dull POY polyester fiber spinning equipment and process. SUMMARY

[0005] The purpose of the present application is to provide a high-elasticity semi-dull POY polyester fiber spinning equipment and process to solve the problems raised in the background.

[0006] To achieve the above-mentioned purpose, the present application provides a high-elasticity semi-dull POY polyester fiber spinning equipment, comprising a device body, a power component is arranged at the end of the device body, and a yarn is movably arranged in the device body;

[0007] A limiting component and a winding rod fixedly installed with the output shaft of the power component are arranged, the other end of the winding rod reciprocally slides a worm, the worm is engaged with a reciprocating turbine through the limiting component, the limiting component comprises a rotating plate, a moving block and a pressing plate, the moving block is rotatably connected with a switching plate which is rotatably connected with the rotating plate, the middle part of the switching plate is fixedly connected with a threaded rod, the threaded rod is threadedly connected with a movable plate, one end of the yarn is wound on the winding rod and penetrates through the movable plate, the other end of the yarn is fixedly connected with the device body, and the pressing plate is in pressing cooperation with the yarn. The structure drives the winding rod to rotate by the power component, and realizes the uniform distribution of the yarn on the winding rod through the cooperative movement of the worm, the turbine and the movable plate in the limiting component;

[0008] The reciprocating sliding of the worm and the meshing transmission of the turbine make the movable plate periodically move away from the winding rod, avoid the accumulation of the wire, and press the wire at a dynamic angle to ensure the tightness and uniformity of the winding, and significantly improve the fiber quality.

[0009] Preferably, a plurality of movable grooves are formed on the switching plate, a convex plate is fixedly connected to the middle of the turbine, the convex plate is fixedly connected with the rotating plate, the end of the rotating plate is rotatably connected with a movable shaft fixedly connected with the pressing plate, and the movable shaft is slidably connected with the movable groove; when the turbine rotates, the convex plate drives the rotating plate to rotate, so that the movable shaft slides in the movable groove, and the switching plate is driven to rotate at a small angle interval. This structure converts the rotary motion of the turbine into intermittent swinging of the switching plate, and then drives the movable plate to move periodically through the threaded rod, so as to accurately control the winding thickness of the wire and avoid the decrease in uniformity caused by local over-thickness.

[0010] Preferably, a groove is formed on the convex plate, the edge of the switching plate is in an arc structure, the convex plate is matched with the arc structure of the switching plate, the groove is rotatably matched with the switching plate, and the position of the rotating plate corresponds to the position of the groove; when the movable shaft slides to the top of the movable groove, the groove of the convex plate is engaged with the arc structure of the switching plate to realize the angle locking of the switching plate. This design ensures that the switching plate maintains a stable position after each swing, prevents the threaded rod from rotating, and thus ensures the accuracy of the movement distance of the movable plate and improves the uniformity of the wire distribution.

[0011] Preferably, a plug rod penetrating through the movable plate is fixedly connected to the moving block; the plug rod limits the movable plate to move only in the axial direction, prevents deflection or vibration caused by threaded transmission, ensures the stability of the movement track of the movable plate, and further improves the uniformity and tightness of the wire winding.

[0012] Preferably, the worm is in a hollow structure, a sliding plate is fixedly connected to the inner wall of the worm, and a sliding groove slidably matched with the sliding plate is formed on the outer surface of the winding rod; the cooperation of the sliding plate and the sliding groove enables the worm to stably slide in the axial direction while rotating with the winding rod, avoids the problem of wire accumulation caused by the rotation of the worm in the traditional equipment, and ensures the uniform distribution of the wire on the winding rod.

[0013] Preferably, two partitions are fixedly connected in the equipment body, the winding rod penetrates through the two partitions, and one end of the wire is wound between the two partitions; the partitions limit the winding area of the wire, prevent the wire from spreading to other parts of the winding rod, support the winding rod to rotate stably, reduce the influence of vibration on the uniformity, and are especially suitable for precise winding of high-elasticity fibers.

[0014] Preferably, the limiting piece further comprises a sliding plate fixedly connected with the moving block, the device body is fixedly connected with a sliding groove plate in sliding cooperation with the sliding plate, a limiting groove is formed in the moving block, the worm and the turbine are movable in the limiting groove, the movable shaft is rotationally connected with the pressing plate, and the other end of the pressing plate is movably connected with the movable plate.

[0015] Preferably, a cooperation groove is formed through the movable plate, a cooperation plate is movably arranged in the cooperation groove through a compression spring, and a plug-in shaft is fixedly connected with the other end of the pressing plate and inserted into the cooperation plate.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] When the power piece is started, the winding rod is driven to rotate, and under the action of the limiting piece, the worm, the turbine and the movable plate move reciprocatingly, so that the silk is uniformly wound on the winding rod.

[0018] The pressing plate moves reciprocatingly and presses the silk, which ensures the reciprocating movement of the movable plate and the uniform winding of the silk, and further ensures the winding angle of the silk on the winding rod. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] Please refer to Figures 1-15The present invention provides a high-elasticity semi-dull POY polyester fiber spinning equipment, including a machine body 1, a power component 2 at the end of the machine body 1, and a filament 3 that is movably fitted inside the machine body 1;

[0037] Existing polyester filament production equipment, such as the "Polyester Filament Production Equipment and Production Process" disclosed in Chinese patent application CN201910234567.X, while improving fiber uniformity and production efficiency to some extent, still needs improvement in the production of irregularly shaped, highly elastic, and soft fabrics. Therefore, it is necessary to develop a specialized spinning equipment and supporting process technology capable of producing high-quality, specially processed, highly elastic, and soft polyester fibers.

[0038] In this application, the process includes a melt conveying system comprising a polyester melt storage tank, a booster pump, a melt filter, a melt distributor, and a melt temperature control system. The melt temperature control system ensures stable melt temperature during conveying, and the melt filter removes impurities from the melt to guarantee fiber quality.

[0039] Cooling system: includes a side-blowing cooling device and a ring-blowing cooling device. The side-blowing cooling device is used for initial cooling of the fiber, and the ring-blowing cooling device is used for further cooling of the fiber to ensure the stability of the fiber during the drawing process.

[0040] Oiling system: includes oil storage tank, oil nozzle and oil circulation device. The oil circulation device ensures uniform distribution of oil on the fiber surface and improves the antistatic and lubricating properties of the fiber.

[0041] The drawing and heat setting system includes a drawing machine, a heat setting device, and a tension control system. The drawing machine draws the fibers to improve their strength and elasticity; the heat setting device heats the fibers to ensure their dimensional stability and wrinkle resistance; and the tension control system ensures the stability of the fiber tension during the drawing and heat setting process.

[0042] The limiter and the winding rod 4 are fixedly installed on the output shaft of the power component 2. The other end of the winding rod 4 has a worm gear 5 that slides back and forth. The worm gear 5 is engaged with a reciprocating turbine 6 through the limiter. The limiter includes a rotating plate 7, a moving block 8, and a pressing plate 9. A switching plate 10 that rotates with the rotating plate 7 is rotatably connected to the moving block 8. A threaded rod 11 is fixedly connected to the middle of the switching plate 10. A movable plate 12 is threadedly connected to the threaded rod 11. One end of the wire 3 is wound on the winding rod 4 and passes through the movable plate 12. The other end of the wire 3 is connected and fixed to the equipment body 1. The pressing plate 9 presses against the wire 3.

[0043] When the power component 2 is started, it drives the winding rod 4 to rotate. Under the action of the limiting component, the moving block 8, worm 5, turbine 6 and movable plate 12 reciprocate, so that the wire 3 is evenly wound on the winding rod 4. The worm 5 and turbine 6 rotate on the moving block 8, and the switching plate 10 rotates at intervals with the rotating plate 7. The threaded rod 11, which reciprocates synchronously, rotates at intervals at intervals, and the movable plate 12 moves away from the winding rod 4 at intervals to prevent the winding thickness of the wire 3 on the winding rod 4 from gradually increasing and the wound wire 3 from contacting the movable plate 12.

[0044] Furthermore, the pressure plate 9 reciprocates, acting to press against the wire 3. On the one hand, this ensures that the movable plate 12 reciprocates, making the wire 3 wind evenly. On the other hand, it acts on the wire 3 to further ensure the winding angle of the wire 3 on the winding rod 4.

[0045] During winding, the power component 2 is installed and connected to the winding rod 4, and the output shaft of the power component 2 rotates, driving the winding rod 4 to rotate synchronously.

[0046] After winding is completed, the installation connection between the power component 2 and the winding rod 4 is released, so that the winding rod 4 can be easily pulled out from the partition 20 and the moving block 8.

[0047] The winding rod 4 is composed of two assembled rods connected and fixed together. One end of the assembled rod is used to wind the wire 33, and the other end is used to insert into the partition 20 and the moving block 8. After winding is completed, the two assembled rods are separated to allow...

[0048] The switching plate 10 has multiple movable slots 13. A protruding plate 14 is fixedly connected to the middle of the turbine 6. The protruding plate 14 is connected and fixed to the rotating plate 7. The end of the rotating plate 7 is rotatably connected to a movable shaft 15 that is fixed to the pressure plate 9. The movable shaft 15 is slidably engaged with the movable slots 13. When the turbine 6 rotates, it drives the movable shaft 15 on the rotating plate 7 to make a circular motion. When the movable shaft 15 rotates to the top, it enters the movable slot 13, thereby driving the switching plate 10 to rotate.

[0049] The convex plate 14 has a groove 16, and the edge of the switching plate 10 has an arc-shaped structure. The convex plate 14 and the arc-shaped structure of the switching plate 10 are matched, and the groove 16 and the switching plate 10 are rotated together. The position of the rotating plate 7 corresponds to the position of the groove 16.

[0050] The movable shaft 15, which makes circular motion, enters the movable groove 13. At this time, the position of the groove 16 corresponds to the position of the switching plate 10. The movable shaft 15 drives the switching plate 10 to rotate. The switching plate 10 rotates in the groove 16, causing the switching plate 10 to rotate by an angle. When the movable shaft 15 disengages from the movable groove 13, the arc-shaped structure of the switching plate 10 presses against the edge of the convex plate 14 (non-groove 16 position), thereby keeping the switching plate 10 in the same position after the angle is adjusted.

[0051] That is, every time the movable shaft 15 rotates once, the switching plate 10 rotates at intervals by a certain angle, thereby driving the threaded rod 11 to rotate at intervals by a small angle, thereby causing the movable plate 12 to move at intervals by a small distance, increasing the distance between the movable plate 12 and the winding rod 4, preventing the winding thickness of the wire 3 on the winding rod 4 from gradually increasing, the wound wire 3 from contacting the movable plate 12, and the small distance between the movable plate 12 and the winding rod 4, which would affect the winding quality of the wire 3.

[0052] The movable plate 12 and the plug shaft 26 are adapted to slide together.

[0053] A rod 17 is fixedly connected to the movable block 8, which passes through the movable plate 12. The rod 17 ensures the horizontal position of the movable plate 12 on the one hand, and ensures that the movable plate 12 can move stably away from or towards the movable block 8 on the other hand.

[0054] The worm 5 has a hollow structure, and a sliding plate 18 is fixedly connected to the inner wall of the worm 5. A groove 19 is provided on the outer surface of the winding rod 4 to slide with the sliding plate 18. By setting the sliding plate 18 and the groove 19, it is ensured that the worm 5 does not affect the sliding of the worm 5 along the winding rod 4 while rotating with the winding rod 4.

[0055] Two partitions 20 are fixedly connected inside the body 1 of the equipment. The winding rod 4 passes through the two partitions 20. One end of the wire 3 is wound between the two partitions 20. The position of the partitions 20 is fixed. The winding rod 4 rotates on the partitions 20. By setting the two partitions 20, the winding area of ​​one end of the wire 3 is guaranteed, so that the wire 3 is evenly wound on the winding rod 4, and the position of the winding rod 4 is guaranteed, so that the winding rod 4 rotates on its original position.

[0056] The limiting component also includes a sliding plate 21 that is fixedly connected to the moving block 8. A sliding groove plate 22 that slides and cooperates with the sliding plate 21 is fixedly connected inside the equipment body 1. A limiting groove 23 is opened in the moving block 8. The turbine 6 and the worm 5 move in the limiting groove 23. The movable shaft 15 is rotatably connected to the pressure plate 9. The other end of the pressure plate 9 is movably cooperated with the movable plate 12.

[0057] The power component 2 drives the winding rod 4 to rotate in its original position (relative to the original position of the equipment body 1). Under the action of the slide plate 18 and the slide groove 19, the worm 5 rotates. This does not affect the worm 5's reciprocating sliding along the winding rod 4. The sliding plate 21 slides along the sliding groove plate 22 to ensure that the moving block 8 moves back and forth without any directional deviation of the angle.

[0058] The worm 5 rotates within the limiting groove 23 in the moving block 8, thereby causing the turbine 6, which is also located in the limiting groove 23, to rotate. The rotation of the turbine 6 drives the convex plate 14 to rotate, causing the outer end of the rotating plate 7 and the movable shaft 15 to make circular motion, thereby causing one end of the pressure plate 9 to make synchronous circular motion. Since the length of the pressure plate 9 is fixed, the other end of the pressure plate 9 moves a small distance on the movable plate 12, thus pulling in the opposite direction, causing the moving block 8, the worm 5, and the turbine 6 to slide along the winding rod 4 in the direction close to the power component 2, and the slide plate 18 slides along the slide groove 19.

[0059] The moving block 8, worm 5, and turbine 6 reciprocate along the direction of the winding rod 4, ensuring the rotation of the worm 5 and turbine 6. The moving plate 12 reciprocates synchronously through the cooperation of the threaded rod 11 and the insert rod 17, driving the stretching reciprocating motion. The silk thread 3 reciprocates on the winding rod 4 between the two partitions 20.

[0060] It is worth noting that the pressure plate 9 makes a small-angle reciprocating movement, which on the one hand ensures the reciprocating movement of the movable plate 12, so that the wire 3 is wound evenly, and on the other hand acts on the wire 3 to further ensure the winding angle of the wire 3 on the winding rod 4.

[0061] A mating groove 24 is provided through the movable plate 12. A mating plate 25 is movable in the mating groove 24 through a compression spring. The other end of the pressure plate 9 is fixedly connected to a plug shaft 26 that inserts into the mating plate 25. One end of the pressure plate 9 makes a circular motion around the convex plate 14 as the rotation center, and the other end of the pressure plate 9 makes an adaptive and small-angle reciprocating rotation, so that the pressure plate 9 moves back and forth and acts on the wire 3. This prevents the angle of the wire 3 between the movable rod and the winding rod 4 from changing when the distance between the movable plate 12 and the winding rod 4 changes, which would cause the wire 3 to be not tightly wound on the winding rod 4 and to easily become loose as the angle of the wire 3 changes.

[0062] The small vertical height of the mating groove 24 results in a small range of vertical movement of the mating plate 25, which in turn results in a small range of movement of the other end of the pressure plate 9, thus tightly fitting the working thread 3 and causing the thread 3 to be wound along the winding rod 4.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
