Description

Technical Field

[0001] This invention belongs to the technical field of drawing and winding machines, specifically relating to a drawing and winding machine for polyester fine denier industrial yarn. Background Technology

[0002] Polyester fine denier industrial yarn is widely used in many fields such as tire cord and rope due to its excellent properties such as high strength and high toughness. In the production process of polyester fine denier industrial yarn, drawing and winding is a crucial step, and the performance of the equipment directly affects product quality and production efficiency.

[0003] Existing polyester fine denier industrial yarn drawing and winding machines mostly employ a linear or relatively loose layout for the drawing rolls. This layout results in a large space occupation for the equipment, requiring companies to invest more in factory construction and equipment installation; moreover, the low integration of the drawing rolls and the relatively independent nature of each component not only increase the complexity of the equipment but also make maintenance and repair more difficult.

[0004] In terms of temperature control, traditional drawing and winding machines often use long strip-shaped drawing rollers to draw and heat at different temperatures. The distance between two adjacent drawing rollers is relatively large, and the temperature interval is obvious. During the drawing and conveying process, the temperature difference between the front and back is very large, which can easily lead to local overheating or insufficient heating, resulting in uneven performance of the filament.

[0005] To avoid the aforementioned technical problems, it is indeed necessary to provide a polyester fine denier industrial yarn drawing and winding machine to overcome the deficiencies in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a polyester fine denier industrial yarn drawing and winding machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a polyester fine denier industrial yarn drawing and winding machine, comprising a machine base, a connecting top frame fixedly connected to the machine base, a connecting plate rotatably connected to the connecting top frame, a plurality of drawing rollers rotatably arranged on the front side of the connecting plate, a plurality of first motors driving the corresponding drawing rollers to rotate are installed on the back side of each drawing roller, the plurality of drawing rollers are in a 300-degree annular structure, and each drawing roller every other one has a heating function; When the filament passes through multiple annular drawing rollers, it is drawn multiple times within the limited space of the annulus, which improves the integration of the drawing rollers. At the same time, the heating function of each drawing roller, combined with this annular structure, creates an annular temperature gradient field with a high temperature in the middle and a low temperature on both sides, which improves the coupling effect between the filament and the heating temperature of the drawing rollers during the spatial transportation process.

[0008] In a preferred embodiment, the machine base is equipped with a positioning conveyor roller group, a drying device and a cooling device. A take-up roller is mounted on the machine base via a support frame. A second motor is mounted on the support frame. The output of the second motor is connected to the take-up roller via a belt and pulley assembly.

[0009] As a preferred embodiment, the machine base is equipped with a steam injection mechanism.

[0010] In a preferred embodiment, the steam injection mechanism includes a motorized frame, which is fixedly mounted on the machine base. A threaded rod is rotatably connected inside the motorized frame, and a third motor for driving the threaded rod to rotate is mounted on one side of the motorized frame.

[0011] In a preferred embodiment, the threaded rod is externally threaded with a displacement block, the displacement block is externally slidably connected to the motor frame, an electric push rod is fixedly connected to the displacement block, and a steam nozzle is fixedly connected to the top of the electric push rod via a crossbar. The steam nozzle changes its eccentric position by displacing the thread in the X direction and the electric push rod in the Y direction, thereby adjusting the steam injection distance to the stretching roller and controlling the steam injection temperature.

[0012] In a preferred embodiment, the machine is fixedly equipped with a steam generator, which is connected to a steam nozzle via a connecting hose. The steam nozzle is provided with multiple annular and wide-angle nozzles. Multiple annular, wide-angle nozzles expand the steam ejection area, achieving uniform heating of the filament bundle.

[0013] In a preferred embodiment, the machine is provided with a liquid accumulation tank for the accumulation of steam liquid.

[0014] As a preferred embodiment, multiple arc-shaped baffles are fixedly installed on the connecting plate, each arc-shaped baffle is located on one side of the corresponding drawing roller with heating function, and each arc-shaped baffle is provided with multiple guide grooves for guiding steam; The arc-shaped baffle blocks the steam jet from the heating roller, reducing the heating effect of the steam.

[0015] As a preferred embodiment, the machine base is provided with a drive mechanism.

[0016] In a preferred embodiment, the drive mechanism includes a first connecting frame and a second connecting frame fixedly connected to the machine base. The first connecting frame is rotatably connected to a rotating rod, one end of which is fixedly connected to the back of the connecting plate, and a worm gear is fixedly installed on the outside of the rotating rod. A fourth motor is fixedly connected to the second connecting frame, and the output shaft of the fourth motor is connected to a worm that meshes with the worm gear.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the cooperation of the machine base, connecting top frame, and connecting plate to form a 300-degree annular structure of multiple drafting rollers. This compact layout significantly saves drafting space compared to traditional linear or loose layouts, improves the integration of drafting rollers, and reduces equipment maintenance difficulty. Furthermore, the presence of a heating drafting roller at intervals, in conjunction with the annular structure, creates an annular temperature gradient field with a high temperature in the middle and low temperatures at both ends. When the filament passes through the annularly arranged drafting rollers, the close proximity of the rollers overcomes the shortcomings of large spacing and obvious temperature intervals in traditional long strip drafting roller layouts. At the same time, due to the strong coupling effect of temperature and space in the annular temperature gradient field, the drafting rollers without heating functions can achieve a suitable transitional heating temperature through heat conduction and spatial field effects. When passing through drafting rollers with different heating temperatures, uniform heating temperature is achieved according to the spatial coupling effect of different heating stages, thereby improving the drafting quality of the filament.

[0018] When the steam generator is started, steam is delivered to the steam nozzles via connecting hoses. Multiple wide-angle, annular nozzles on the nozzles evenly cover the filament bundle along the annular transport path. Given the annular nature of the filament bundle transport path, this design overcomes the shortcomings of traditional heating methods, which struggle to provide comprehensive and uniform heating, ensuring consistent heating of the filament bundle. The steam heating, combined with the spaced-apart heating rollers, effectively reduces the stress on the filament bundle during transport and drawing, lowering the risk of internal structural damage. Furthermore, a third motor drives a threaded rod to rotate, causing a displacement block to slide within a motorized frame, thereby adjusting the position of the steam nozzles at the top of the electric push rod. This allows the steam nozzles to change the distance between the nozzles and the drawing rollers based on different eccentric positions. Combined with multiple heating rollers, this achieves multi-dimensional adjustment of the filament bundle drawing temperature, significantly improving the accuracy of temperature control.

[0019] When the steam nozzle of this invention heats the yarn bundle with steam, some of the steam inevitably escapes to the drafting roller, which has a heating function. At this time, the arc-shaped baffle located on one side of the drafting roller can effectively shield the steam spray surface of the drafting roller. This shielding can greatly reduce the interference of the escaped steam with the drafting roller's own heating system, and prevent the steam from causing uneven temperature distribution on the surface of the drafting roller, which would affect its heating effect on the yarn bundle. The multiple guide grooves opened on the arc-shaped baffle can guide the small amount of steam that may come into contact with the drafting roller, so that it flows in a specific direction. In addition to further reducing the adverse effects of steam on the heating effect of the drafting roller, it can also allow the steam to be transported to the drafting roller without a heating function, further increasing the coupling of spatial temperature.

[0020] Driven by a fourth motor, this invention can rotate a worm gear, which in turn drives a worm wheel, causing the rotating rod to rotate. The connecting disc then rotates precisely, allowing for precise adjustment of the drafting angles of multiple drafting rollers as needed. Furthermore, a certain degree of rotation can alter the drafting direction; for example, every 1-degree rotation of the drum changes the winding angle of the filament bundle on the drafting rollers by 0.5-1.0 degrees. This characteristic enables operators to adjust the orientation of the fiber molecular chains in real time, effectively meeting the diverse needs of different products for fiber molecular chain orientation, greatly improving product quality and performance, and broadening the applicability of the equipment.

[0023] The present invention will be further described below with reference to embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figure 1-10 This invention provides a polyester fine denier industrial yarn drawing and winding machine, including a machine base 1, a connecting top frame 2 fixedly connected to the machine base 1, a connecting plate 3 rotatably connected to the connecting top frame 2, a plurality of drawing rollers 4 rotatably arranged on the front side of the connecting plate 3, a plurality of first motors 5 driving the corresponding drawing rollers 4 to rotate are installed on the back side of each drawing roller 4, the plurality of drawing rollers 4 are in a 300-degree annular structure, and each drawing roller 4 with an interval of one has a heating function; When the filament passes through multiple annular drawing rollers 4, the filament is drawn multiple times within the limited space of the annulus, which improves the integration of the drawing rollers 4. At the same time, the heating function of each drawing roller 4, combined with this annular structure, creates an annular temperature gradient field with a high temperature in the middle and a low temperature on both sides, which improves the coupling effect between the filament and the heating temperature of the drawing rollers 4 during the spatial transportation process.

[0026] like Figure 3 As shown, the machine base 1 is equipped with a positioning conveyor roller group 6, a drying device 7 and a cooling device 8. A take-up roller 10 is installed on the machine base 1 via a support frame 9. A second motor 11 is installed on the support frame 9. The output part of the second motor 11 is connected to the take-up roller 10 via a belt and pulley assembly 12.

[0027] like Figure 1 As shown, a steam injection mechanism 13 is installed on the machine base 1.

[0028] like Figure 6 and Figure 7 As shown, the steam injection mechanism 13 includes a motor frame 131, which is fixedly mounted on the machine base 1. A threaded rod 132 is rotatably connected inside the motor frame 131, and a third motor 133 that drives the threaded rod 132 to rotate is mounted on one side of the motor frame 131.

[0029] like Figure 7 As shown, the threaded rod 132 is externally threaded to a displacement block 134, the displacement block 134 is externally slidably connected to the motor frame 131, an electric push rod 135 is fixedly connected to the displacement block 134, and a steam nozzle 137 is fixedly connected to the top of the electric push rod 135 through a crossbar 136.

[0030] The steam nozzle 137 changes its eccentric position by the X-direction displacement of the thread and the Y-direction displacement of the electric push rod 135, so as to adjust its different steam injection distance to the drafting roller 4 and achieve control over its steam injection temperature.

[0031] like Figure 7 As shown, a steam generator 138 is fixedly installed on the machine base 1. The steam generator 138 is connected to a steam nozzle 137 via a connecting hose 139. The steam nozzle 137 is provided with multiple annular and wide-angle nozzles 1310. Multiple annular and wide-angle nozzles 1310 expand the steam ejection area, achieving uniform heating of the filament bundle.

[0032] When the steam generator 138 is started, steam is delivered to the steam nozzle 137 via the connecting hose 139. Multiple annular and wide-angle nozzles 1310 on the nozzle can evenly cover the filament bundle along the annular conveying path with steam. Given the annular nature of the filament bundle conveying path, this design overcomes the drawback of traditional heating methods that are difficult to heat evenly and comprehensively, ensuring consistent heating of the filament bundle. The steam heating works in conjunction with the spaced-apart heating rollers 4 to effectively reduce the stress on the filament bundle during conveying and drawing, and reduce the risk of damage to the internal structure of the filament bundle. In addition, the threaded rod 132 is driven to rotate by the third motor 133, which drives the displacement block 134 to slide within the motorized frame 131, thereby adjusting the position of the steam nozzle 137 at the top of the electric push rod 135. This allows the steam nozzle 137 to change the distance between the nozzle 1310 and the drawing roller 4 according to different eccentric positions. In conjunction with multiple heating rollers 4, multi-dimensional adjustment of the filament bundle drawing temperature is achieved, significantly improving the adjustment accuracy of the filament bundle drawing temperature.

[0033] like Figure 1 As shown, the machine base 1 is provided with a liquid accumulation tank 14 for the accumulation of steam liquid.

[0034] like Figure 8 and Figure 9As shown, multiple arc-shaped baffles 15 are fixedly installed on the connecting plate 3. Each arc-shaped baffle 15 is located on one side of the corresponding stretching roller 4 with heating function. Each arc-shaped baffle 15 has multiple guide grooves 16 for guiding steam. The arc-shaped baffle 15 blocks the steam jet surface of the heating roller 4, reducing the heating effect of the steam.

[0035] When the steam nozzle 137 sprays steam to heat the yarn bundle, some steam will inevitably escape to the drafting roller 4 which has a heating function. At this time, the arc-shaped baffle 15 located on one side of the drafting roller 4 can effectively block the steam spray surface of the drafting roller 4. Through this blocking, the interference of the escaped steam to the heating system of the drafting roller 4 itself can be greatly reduced, and the steam may cause uneven temperature distribution on the surface of the drafting roller 4, affecting its heating effect on the yarn bundle. The multiple guide grooves 16 opened on the arc-shaped baffle 15 can guide the small amount of steam that may come into contact with the drafting roller 4, so that it flows in a specific direction. In addition to further reducing the adverse effects of steam on the heating effect of the drafting roller 4, it can also allow the steam to be transported to the drafting roller 4 which does not have a heating function, further increasing the coupling of spatial temperature.

[0036] like Figure 2 As shown, a drive mechanism 17 is provided on the machine base 1.

[0037] like Figure 10 As shown, the drive mechanism 17 includes a first connecting frame 171 and a second connecting frame 172 fixedly connected to the machine base 1. The first connecting frame 171 is rotatably connected to a rotating rod 173. One end of the rotating rod 173 is fixedly connected to the back of the connecting plate 3, and a worm gear 174 is fixedly installed on the outside of the rotating rod 173. A fourth motor 175 is fixedly connected to the second connecting frame 172. The output shaft of the fourth motor 175 is connected to a worm 176 that meshes with the worm gear 174.

[0038] Driven by the fourth motor 175, the worm gear 176 rotates, which in turn drives the worm wheel 174 to rotate, causing the rotating rod 173 to rotate. The connecting disc 3 rotates accordingly. The connecting disc 3 can rotate precisely, which allows for changing the drafting angle of multiple drafting rollers 4 as needed. Furthermore, a certain degree of rotation can change the drafting direction. For example, for every 1 degree the drum rotates, the winding angle of the filament bundle on the drafting roller 4 will change by 0.5-1.0 degrees. This characteristic allows operators to adjust the orientation direction of the fiber molecular chains in real time, effectively meeting the diverse needs of different products for fiber molecular chain orientation, greatly improving product quality and performance, and broadening the applicability of the equipment.

[0039] The working principle and usage process of this invention: The filament bundle is conveyed from the starting position, first passing through the positioning conveyor roller group 6 for precise guidance, and then entering the area of ​​the drawing roller 4 for multiple drawing processes. After the drawing is completed, the filament bundle passes through the drying equipment 7 and the cooling equipment 8 in sequence to achieve drying and cooling treatment. Finally, the second motor 11 drives the winding roller 10 through the belt and pulley assembly 12 to wind the processed filament bundle into a finished product. During this period, the steam injection mechanism 13 adds flexibility to the heating of the filament bundle. The steam generator 138 generates steam, which is delivered to the steam nozzle 137 through the connecting hose 139. Multiple annular and wide-angle nozzles 1310 evenly cover the filament bundle for steam injection heating. The steam nozzle 137 drives the threaded rod 132 through the third motor 133, which drives the displacement block 134 to slide. The position is adjusted in conjunction with the electric push rod 135 to achieve precise control of the steam injection temperature. In conjunction with the heating of the drawing roller 4, the stress of the filament bundle is reduced and the accuracy of the drawing temperature adjustment is improved. The liquid collection tank 14 opened on the machine 1 collects the steam condensate in time to ensure the normal operation of the equipment. The arc-shaped baffle 15 on the connecting plate 3 effectively blocks the escaping steam, reducing its interference with the heating roller 4. Its guide groove 16 can also guide the steam flow and improve the spatial coordination of heating temperature. When it is necessary to adjust the drafting direction or fiber molecular chain orientation, the drive mechanism 17 on the machine 1 comes into play. The fourth motor 175 drives the worm gear 176, which in turn drives the worm wheel 174 and the rotating rod 173, causing the connecting disc 3 to rotate and change the drafting direction to meet different production needs and achieve efficient and precise polyester fine denier industrial yarn drafting and winding production.
