Description
Technical Field
[0001] This utility model relates to the technical field of polyester filament processing equipment, and in particular to a doubling machine for FDY high-strength bright polyester retwisted yarn. Background Technology
[0002] FDY high-strength bright polyester yarn has excellent tensile strength and good resistance to chemicals such as acids and alkalis. It is not easily damaged by chemical reactions in general chemical environments, and its strength is higher than that of ordinary polyester yarn. This characteristic makes it less prone to breakage when subjected to large external forces, which can meet some application scenarios with extremely high material strength requirements. One of its significant features is its bright color. The yarn surface is smooth and has good light reflection ability, which can present a bright and bright luster effect. This luster not only enhances the appearance and texture of the product, making it more attractive, but also plays an important role in some decorative fields.
[0003] However, existing technologies still have the following problems:
[0004] The production and processing of FDY high-strength bright polyester filament requires the use of a retwisting and doubling machine to retwist and double the yarn. In practical applications, the yarn guiding mechanism is difficult to adjust in position as needed during the production of FDY high-strength bright polyester filament, and it is also difficult to stretch and tighten the polyester yarn as required. This results in poor versatility. Furthermore, during the winding process after the production of FDY high-strength bright polyester filament, it is difficult to easily pull and wind the polyester yarn, and the winding is not uniform and flat, which is not conducive to its widespread use.
[0005] To address the aforementioned problems, the inventors proposed an FDY polyester high-strength bright retwisted yarn doubling machine to solve these issues. Utility Model Content

[0011] Preferably, in order to better drive the rotation of the rotating roller and the follower roller, the winding mechanism includes a fixed disk fixedly connected to the top surface of the support platform. A winding motor is fixedly connected to one side surface of the fixed disk. A rotating roller is movably connected to the side surface of the fixed disk away from the winding motor via a bearing. One end of the rotating roller is fixedly connected to the output end of the winding motor. A follower roller is provided at the end of the rotating roller away from the winding motor.
[0012] Preferably, in order to better limit the position of the push plate, an insertion rod is fixedly connected to one side surface of the follower roller, and an insertion hole matching the structural size of the insertion rod is opened on one side surface of the rotating roller. One end of the follower roller is movably connected to the push plate through a bearing. An anti-detachment block is fixedly connected to the bottom surface of the push plate.

By rotating the rotating screw, the upper and lower plates can move up and down in the positioning box. The positioning rod can be inserted into the positioning hole to achieve precise positioning of the moving plate and the entire guiding mechanism. This allows multiple guiding mechanisms to be flexibly adjusted according to production needs, adapting to the guiding requirements of different specifications of polyester yarn, improving the versatility of the equipment. In addition, the electric push rod can drive the second guiding box to move up and down to stretch and tighten the polyester yarn, ensuring that the yarn maintains a stable direction during the retwisting and doubling process.
[0017] By setting up a traction mechanism, the servo motor drives the lead screw to rotate. The lead screw is threadedly connected to the sleeve block, which allows the moving plate to slide stably on the top surface of the guide box. This, in turn, drives the traction box and traction roller to move smoothly, thereby enabling the retwisted polyester yarn to be wound evenly. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0024] Please see Figures 1-4 As shown, an FDY high-strength bright polyester retwisting and doubling machine includes a support platform 1. The top surface of the support platform 1 is provided with a retwisting and doubling machine body 2, which is a known existing device. The retwisting and doubling machine body 2 can retwist and double polyester yarn to produce the required FDY high-strength bright polyester yarn. This is a common technical means and will not be described in detail here. The top surface of the support platform 1 is provided with a guide mechanism 3, which includes a moving plate 31 that is slidably connected to the top surface of the support platform 1. The bottom surface of the moving plate 31 is fixedly connected with a locking block 6. The top surface of the support platform 1 is provided with a slot that matches the structural size of the locking block 6. The locking block 6 fixedly connected to the bottom surface of the moving plate 31 cooperates with the slot on the top surface of the support platform 1.

The bottom surface of the inner cavity of the positioning box 36 is flush with the top surface of the motion plate 31. All are provided with positioning holes that match the structural dimensions of the positioning rod 39. The bottom end of the positioning rod 39 is fixedly connected to an anti-slip soft layer made of rubber. Rotating the rotating rod 38, which is fixedly connected to the outer surface of one end, causes the upper and lower plates 37 to move up and down within the positioning box 36. When the upper and lower plates 37 move to the appropriate position, the positioning rod 39, which is fixedly connected to the bottom surface of the upper and lower plates 37, will be inserted into the positioning holes that are both opened through the bottom surface of the inner cavity of the positioning box 36 and the top surface of the moving plate 31. The anti-slip soft layer fixedly connected to the bottom end of the positioning rod 39 presses against the surface of the support platform 1, thereby ensuring the stability of the moving plate 31.
[0026] A winding mechanism 4 is provided on the top surface of the support platform 1. The winding mechanism 4 includes a fixed disk 41 fixedly connected to the top surface of the support platform 1. A winding motor 42 is fixedly connected to one side surface of the fixed disk 41. A rotating roller 43 is movably connected to the side surface of the fixed disk 41 away from the winding motor 42 via a bearing. One end of the rotating roller 43 is fixedly connected to the output end of the winding motor 42. A follower roller 44 is provided at the end of the rotating roller 43 away from the winding motor 42. The output end of the winding motor 42 drives the rotating roller 43, which is movably connected to the side surface of the fixed disk 41 away from the winding motor 42 via a bearing, to rotate. The follower roller 44 and the rotating roller... The roller 43 rotates synchronously. An insertion rod 45 is fixedly connected to one side surface of the follower roller 44.

A servo motor 52 is fixedly connected to one end of the guide rail box 51, and a lead screw 53 is fixedly connected to the output end of the servo motor 52 at one end. The end of the lead screw 53 away from the servo motor 52 is movably connected to the guide rail box 51 through a bearing. The output end of the servo motor 52 drives the lead screw 53 to rotate.

To ensure stability, the inner cavity of the guide rail box 51 is provided with a lead screw body 53. The top surface of the guide rail box 51 is slidably connected to the moving plate 54. The bottom surface of the moving plate 54 is fixedly connected with a sleeve block 57. The sleeve block 57 is threadedly connected to the outer surface of the lead screw body 53. When the lead screw body 53 rotates, the sleeve block 57 will move along the lead screw body 53, thereby driving the moving plate 54 to slide stably on the top surface of the guide rail box 51. The top surface of the moving plate 54 is fixed with a traction box 55. The inner surface of the traction box 55 is movably connected to a traction roller 56 through a bearing.
[0028] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as the retwisting and doubling machine body 2, the electric push rod 33, the winding motor 42, and the servo motor 52, should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0029] Working principle: During use, according to production needs, the operator pushes the motion plate 31 to slide on the top surface of the support platform 1. The locking block 6 fixedly connected to the bottom surface of the motion plate 31 cooperates with the slot opened on the top surface of the support platform 1 to ensure the stability of the movement.
[0030] Furthermore, the operator rotates the rotating rod fixedly connected to the outer surface of one end of the rotating screw 38. Since one end of the rotating screw 38 is movably connected to the upper and lower plates 37 through a bearing, and the rotating screw 38 is connected to the top surface of the upper and lower plates 37, rotating the rotating screw 38 will cause the upper and lower plates 37 to move up and down within the positioning box 36. When the upper and lower plates 37 move to the appropriate position, the positioning rod 39 fixedly connected to the bottom surface of the upper and lower plates 37 will be inserted into the positioning holes that penetrate both the bottom surface of the inner cavity of the positioning box 36 and the top surface of the moving plate 31, thereby achieving precise positioning of the moving plate 31 and the entire guide mechanism 3, and flexibly adjusting the position of the moving plate 31.
[0031] Furthermore, the top surface of the support platform 1 is provided with a screw hole that matches the size of the fitting screw structure. When the fitting screw is removed, the push plate 46 and the fitting plate 47 assembly slide, the follower roller 44 separates from the rotating roller 43, and then the yarn spool is clamped on the outer surface of the rotating roller 43. The outer surfaces of both the rotating roller 43 and the follower roller 44 are coated with an anti-slip silicone soft layer to ensure the stability of the yarn spool. The push plate 46 is moved again, the insertion rod 45 is inserted into the insertion hole, and the rotating roller 43 and the follower roller 44 are combined. At this time, the yarn spool is located on the outer surface of the rotating roller 43 and the follower roller 44 assembly.
[0032] Furthermore, the raw material yarn of FDY high-strength bright polyester yarn is introduced into the guiding mechanism 3. The yarn passes through the guide roller 35 connected to the inner surface of the first guide box 32 and the second guide box 34 by bearings. The electric push rod 33 fixedly connected to the top surface of the motion plate 31 is activated. The second guide box 34 fixedly connected to the telescopic end of the electric push rod 33 will move up and down under the action of the electric push rod 33, thereby stretching and tightening the polyester yarn to ensure that the yarn maintains a stable direction during the retwisting and doubling process. After passing through the guiding mechanism 3, the raw material yarn enters the retwisting and doubling machine body 2 for retwisting and doubling operations.
[0033] Furthermore, the produced FDY high-strength bright polyester filament passes through the traction roller 56 and is wound around the surface of the yarn bobbin outside the rotating roller 43 and the follower roller 44. The winding motor 42 is started, and the output end of the winding motor 42 drives the rotating roller 43, which is connected to the fixed plate 41 on the side away from the winding motor 42 through the bearing, to rotate. The follower roller 44 rotates synchronously, and the yarn bobbin also rotates.
[0034] Furthermore, the servo motor 52, which is fixedly connected to one end of the guide rail box 51 on the top surface of the support platform 1, is activated. The output end of the servo motor 52 drives the lead screw body 53 to rotate. Since the sleeve block 57, which is fixedly connected to the bottom surface of the moving plate 54, is threadedly connected to the outer surface of the lead screw body 53, when the lead screw body 53 rotates, the sleeve block 57 will move along the lead screw body 53, thereby driving the moving plate 54 to slide stably on the top surface of the guide rail box 51. At this time, the FDY high-strength bright polyester yarn will reciprocate and follow the traction box 55 to move, and evenly wind the FDY high-strength bright polyester yarn on the outer surface of the yarn spool.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
