Description

Technical Field

[0001] The invention belongs to the technical field of drafting and winding machines, and in particular relates to a polyester fine-denier industrial yarn drafting and winding machine. Background Art

[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, drafting and winding is an extremely critical link, and its equipment performance is directly related to product quality and production efficiency.

[0003] The existing polyester fine denier industrial yarn drafting and winding machines mostly use linear or loose layouts for the drafting rollers. This layout results in the equipment taking up a large space, and enterprises need to invest more costs in plant construction and equipment placement; in addition, the drafting rollers have a low integration level and each component is relatively independent, which not only increases the complexity of the equipment, but also makes maintenance and overhaul more difficult.

[0004] In terms of temperature control, traditional stretching and winding machines often use long stretching rollers to perform stretching heating at different temperatures. The distance between two adjacent stretching rollers is relatively far, and the temperature interval is obvious. During the stretching and conveying process, it is easy for the temperature difference between the front and back of the yarn tow to be too large, and it is easy for local overheating or insufficient heating to occur, resulting in uneven yarn performance.

[0005] In order to avoid the above technical problems, it is necessary to provide a polyester fine denier industrial yarn drawing and winding machine to overcome the above defects in the prior art. Summary of the invention

[0006] The object of the present invention is to provide a polyester fine denier industrial yarn drawing and winding machine to solve the problems raised in the above background technology.

At the same time, the heating function of each interval drawing roller cooperates with this annular structure to construct an annular temperature gradient field with high temperature in the middle and low temperature on both sides, thereby improving the coupling effect between the filament bundle and the heating temperature of the drawing roller during the spatial transportation process.

[0008] As a preferred embodiment, the machine is provided with a positioning conveying roller group, a drying device and a cooling device, a winding roller is installed on the machine through a support frame, a second motor is installed on the support frame, and the output part of the second motor is connected to the winding roller through a belt and pulley assembly.

[0009] As a preferred embodiment, a steam injection mechanism is provided on the machine platform.

[0010] As a preferred embodiment, the steam injection mechanism includes a motorized frame, which is fixedly mounted on the machine platform, 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] As a preferred embodiment, the threaded rod is externally threadedly connected with a displacement block, the displacement block is externally slidably connected in a motorized frame, the displacement block is fixedly connected with an electric push rod, and the top end of the electric push rod is fixedly connected with a steam nozzle via a transverse rod; The steam nozzle changes different eccentric positions through the displacement of the thread in the X direction and the electric push rod in the Y direction to adjust the different steam spraying distances to the drafting roller and control the steam spraying temperature.

[0012] As a preferred embodiment, the machine is fixedly equipped with a steam generator, the steam generator is connected to a steam nozzle through a connecting hose, and the steam nozzle is provided with a plurality of ring-shaped and wide-angle nozzles; Multiple annular and wide-angle nozzles expand the steam spraying area to achieve uniform heating of the filament bundle.

[0013] As a preferred embodiment, the machine is provided with a liquid storage tank for accumulating steam and liquid.

[0014] As a preferred embodiment, a plurality of arc-shaped baffles are fixedly mounted on the connecting plate, each of the arc-shaped baffles is located on one side of the corresponding drafting roller with heating function, and each of the arc-shaped baffles is provided with a plurality of guide grooves for guiding steam; The arc-shaped baffle shields the steam spraying surface of the drafting roller with heating function, thereby reducing the heating effect of the steam on it.

[0015] As a preferred implementation scheme, a driving mechanism is provided on the machine platform.

[0016] As a preferred embodiment, the driving mechanism includes a first connecting frame and a second connecting frame fixedly connected to the machine platform, the first connecting frame is rotatably connected to a rotating rod, one end of the rotating rod is fixedly connected to the back side of the connecting disk, and a worm gear is fixedly installed on the outside of the rotating rod, and the second connecting frame is fixedly connected to a fourth motor, and the output shaft of the fourth motor is connected to a worm meshing with the worm gear.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention cooperates with the machine, the connecting top frame and the connecting disk to make multiple drafting rollers form a 300-degree annular structure. Compared with the traditional linear or loose layout, this compact layout greatly saves drafting space, improves the integration of drafting rollers, and reduces the difficulty of equipment maintenance. In addition, each drafting roller with a heating function is coordinated with the annular structure to construct an annular temperature gradient field with a high temperature in the middle and low temperatures on both sides. When the filaments pass through the annularly arranged drafting rollers, the drafting rollers are closely adjacent to each other, which overcomes the defects of the traditional long strip drafting roller layout with a large distance between adjacent rollers and a significant temperature interval. At the same time, due to the strong coupling effect between the temperature and space of the annular temperature gradient field, the interval drafting rollers without heating function can have a transitional and suitable heating temperature with the help of heat conduction and spatial field effects. When passing through drafting rollers with different heating temperatures, a uniform heating temperature is achieved according to the spatial coupling effect in different heating stages, thereby improving the drafting quality of the filaments.

[0018] When the steam generator of the present invention is started, steam is transported to the steam nozzle through the connecting hose. The multiple annular and wide-angle nozzles on the nozzle can evenly cover the steam on the filament bundle in the annular conveying path. In view of the annular characteristics of the filament bundle conveying path, this design overcomes the disadvantage that the traditional heating method is difficult to heat comprehensively and evenly, and ensures the heating consistency of the filament bundle. The steam heating and the intervally arranged drawing rollers with heating function cooperate with each other, effectively reducing the stress on the filament bundle during the conveying and drawing process, and reducing the risk of damage to the internal structure of the filament bundle. In addition, the threaded rod is driven to rotate by the third motor, driving the displacement block to slide in the motorized frame, thereby adjusting the position of the steam nozzle at the top end of the electric push rod, so that the steam nozzle can change the distance between the nozzle and the drawing roller according to different eccentric positions, and cooperate with multiple drawing rollers with heating function to achieve multi-dimensional adjustment of the drawing temperature of the filament bundle, which significantly improves the adjustment accuracy of the drawing temperature of the filament bundle.

[0019] In the present invention, when the steam nozzle sprays steam to heat the filament bundle, part of the steam will inevitably escape to the drawing roller with a heating function. At this time, the arc-shaped baffle plate located on one side of the drawing roller can effectively shield the steam spray surface of the drawing roller. Through this shielding, the interference of the escaped steam on the heating system of the drawing roller itself can be greatly reduced, and the steam can be prevented from causing uneven temperature distribution on the surface of the drawing roller, thereby affecting the heating effect of the filament bundle. The multiple guide grooves provided on the arc-shaped baffle plate can guide a small amount of steam that may contact the drawing roller to flow in a specific direction. In addition to further reducing the adverse effects of steam on the heating effect of the drawing roller, the steam can also be transported to the drawing roller without a heating function, thereby further increasing the coupling of the spatial temperature.

[0020] The present invention can drive the worm to rotate under the drive of the fourth motor, and the worm drives the worm wheel to rotate, thereby rotating the rotating rod, and the connecting disk rotates accordingly. The connecting disk can realize precise rotation. On the one hand, the drafting angles of multiple drafting rollers can be changed as needed. On the other hand, a certain degree of rotation can change the drafting direction. For example, for every 1 degree rotation of the drum, the winding angle of the fiber bundle on the drafting roller will change by 0.5-1.0 degrees. This feature enables the operator to adjust the orientation direction of the fiber molecular chain in real time, effectively meeting the diverse needs of different products for the orientation of the fiber molecular chain, greatly improving the quality and performance of the product, and broadening the scope of application of the equipment.

At the same time, the heating function of each interval drawing roller 4 cooperates with the annular structure to construct an annular temperature gradient field with high temperature in the middle and low temperature on both sides, thereby improving the coupling effect between the filament bundle and the heating temperature of the drawing rollers 4 during the spatial transportation process.

[0026] like Figure 3 As shown, the machine 1 is provided with a positioning conveying roller group 6, a drying device 7 and a cooling device 8. A winding roller 10 is installed on the machine 1 through 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 winding roller 10 through a belt and pulley assembly 12.

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

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

[0029] like Figure 7 As shown, the external threaded connection of the threaded rod 132 is connected with a displacement block 134, the external part of the displacement block 134 is slidably connected in the motorized frame 131, the displacement block 134 is fixedly connected with an electric push rod 135, and the top of the electric push rod 135 is fixedly connected with a steam nozzle 137 through a transverse rod 136;

[0030] The steam nozzle 137 changes different eccentric positions through the displacement of the thread in the X direction and the displacement of the electric push rod 135 in the Y direction to adjust the different steam spraying distances to the drafting roller 4, thereby realizing the control of the steam spraying temperature.

[0031] like Figure 7 As shown, the machine 1 is fixedly installed with a steam generator 138, and the steam generator 138 is connected to a steam spray head 137 through a connecting hose 139, and a plurality of ring-shaped and wide-angle nozzles 1310 are arranged on the steam spray head 137; The plurality of ring-shaped and wide-angle nozzles 1310 expand the steam ejection area, thereby achieving uniform heating of the filament bundle.

[0032] When the steam generator 138 is started, the steam is transported to the steam nozzle 137 through the connecting hose 139. The multiple annular and wide-angle nozzles 1310 on the nozzle can evenly cover the steam on the tow in the annular conveying path. In view of the annular characteristics of the tow conveying path, this design overcomes the disadvantage that the traditional heating method is difficult to heat evenly and comprehensively, and ensures the consistency of heating of the tow. The steam heating cooperates with the intervally arranged drafting rollers 4 with heating function to effectively reduce the stress on the tow during the conveying and drafting process and reduce the risk of damage to the internal structure of the tow. In addition, the threaded rod 132 is driven to rotate by the third motor 133, driving the displacement block 134 to slide in the motor frame 131, thereby adjusting the position of the steam nozzle 137 at the top of the electric push rod 135, so that the steam nozzle 137 can change the distance between the nozzle 1310 and the drafting roller 4 according to different eccentric positions, and cooperate with multiple drafting rollers 4 with heating function to achieve multi-dimensional adjustment of the drafting temperature of the tow, which significantly improves the adjustment accuracy of the drafting temperature of the tow.

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

[0034] like Figure 8 and Fig. 9As shown, a plurality of arc-shaped baffles 15 are fixedly mounted on the connecting plate 3, each of the arc-shaped baffles 15 is located on one side of the corresponding drafting roller 4 with heating function, and each of the arc-shaped baffles 15 is provided with a plurality of guide grooves 16 for guiding steam; The arc-shaped baffle 15 shields the steam spraying surface of the drafting roller 4 with heating function, thereby reducing the heating effect of the steam on it.

[0035] When the steam nozzle 137 sprays steam to heat the filament bundle, part of the steam will inevitably escape to the drawing roller 4 with a heating function. At this time, the arc-shaped baffle 15 located on one side of the drawing roller 4 can effectively shield the steam spray surface of the drawing roller 4. Through this shielding, the interference of the escaped steam on the heating system of the drawing roller 4 itself can be greatly reduced, and the steam can be prevented from causing uneven temperature distribution on the surface of the drawing roller 4 and affecting its effect on the heating effect of the filament bundle. The multiple guide grooves 16 opened on the arc-shaped baffle 15 can guide a small amount of steam that may contact the drawing roller 4 to flow in a specific direction. In addition to further reducing the adverse effects of steam on the heating effect of the drawing roller 4, the steam can also be transported to the drawing roller 4 without a heating function, thereby further increasing the coupling of the spatial temperature.

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

[0037] like Fig.10 As shown, the driving mechanism 17 includes a first connecting frame 171 and a second connecting frame 172 fixedly connected to the machine table 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 disk 3, and a worm gear 174 is fixedly installed on the outside of the rotating rod 173, and a fourth motor 175 is fixedly connected to the second connecting frame 172, and the output shaft of the fourth motor 175 is connected to a worm 176 meshing with the worm gear 174.

[0038] Driven by the fourth motor 175, the worm 176 can be driven to rotate, and the worm 176 drives the worm wheel 174 to rotate, thereby rotating the rotating rod 173, and the connecting disk 3 rotates accordingly. The connecting disk 3 can achieve precise rotation. On the one hand, the drafting angles of multiple drafting rollers 4 can be changed as needed. On the other hand, a certain degree of rotation can change the drafting direction. For example, for every 1 degree rotation of the drum, the winding angle of the fiber bundle on the drafting roller 4 will change by 0.5-1.0 degrees. This feature enables the operator to adjust the orientation direction of the fiber molecular chain in real time, effectively meeting the diverse needs of different products for the orientation of the fiber molecular chain, greatly improving the quality and performance of the product, and broadening the scope of application of the equipment.

[0039] The working principle and use process of the present invention are as follows: the tow is transported from the starting position, firstly guided precisely by the positioning conveying roller group 6, and then enters the drafting roller 4 area for multiple drafting processes. After the drafting is completed, the tow passes through the drying device 7 and the cooling device 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 tow into a finished product. During this period, the steam spray mechanism 13 adds flexibility to the heating of the tow. The steam generator 138 generates steam, which is transported to the steam nozzle 137 through the connecting hose 139.

The steam nozzle 137 drives the threaded rod 132 through the third motor 133, drives the displacement block 134 to slide, and cooperates with the electric push rod 135 to adjust the position, so as to achieve precise control of the steam spray temperature, cooperate with the heating of the drafting roller 4, reduce the stress of the tow, and improve the precision of drafting temperature regulation. The liquid accumulating tank 14 opened on the machine 1 collects the steam condensed liquid 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 drafting roller 4 with heating function, and its guide groove 16 can also guide the flow of steam to improve the spatial coordination of the heating temperature; When it is necessary to adjust the stretching direction or the orientation of the fiber molecular chain, the driving mechanism 17 on the machine 1 comes into play, and the fourth motor 175 drives the worm 176, which drives the worm wheel 174 and the rotating rod 173 to rotate the connecting disk 3, thereby changing the stretching direction to meet different production needs and realize efficient and precise polyester fine denier industrial yarn stretching and winding production.
