Description

Technical Field

[0001] This utility model relates to the technical field of dual extrusion spinning and winding equipment, and in particular to a yarn threading guide structure for dual extrusion spinning and winding equipment. Background Technology

[0002] Dual extrusion spinning and winding equipment is a specialized piece of equipment in the chemical fiber production field. Its core feature is that it is equipped with two independent extrusion systems, which can efficiently produce composite fibers with a core-sheath structure and a parallel structure. It is widely used in textile, non-woven fabric and other industries. A threading guide structure of dual extrusion spinning and winding equipment is a key component that is adapted to bicomponent melt extrusion. It can simultaneously guide multiple strands of filaments, control tension to prevent splitting and breakage, and achieve uniform winding through a reciprocating mechanism, ensuring stable forming of composite fibers such as core-sheath and improving product quality.

[0003] In the threading and guiding structure of a dual extrusion spinning and winding equipment, the extruded filaments enter the guide tube. The guide tube precisely plans the filament path and uses its fixed channel direction to constrain the filament trajectory, ensuring its stable forward movement. Traditional threading and guiding structures are difficult to automatically adjust parameters such as guiding angle and spacing, requiring frequent manual adjustments. Furthermore, errors in manual adjustments can affect the filament guiding effect. Existing technology uses adaptive guiding components and guide tubes designed with elastic materials and flexible structures. When the filaments pass through, the guide tube can automatically deform to a certain extent according to the thickness, tension, and other characteristics of the filaments, thereby adaptively adjusting the guiding space and angle to adapt to the guiding needs of different spinning lines and reduce reliance on manual adjustments and complex automated adjustments. However, during the spinning line guiding process, some fiber debris and impurities are generated and adhere to the outside of the spinning line, causing the spinning line to break due to scratches. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a threading guide structure for a dual extrusion spinning and winding equipment, which aims to improve the problem in the prior art where fiber debris adheres to the spinning thread during the guiding of the spinning thread, causing scratches and breakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a threading guide structure for a dual extrusion spinning and winding equipment, comprising a winding device, wherein a threading guide mechanism is fixedly connected to the left side of the winding device, the threading guide mechanism being used to guide the spinning yarn; the threading guide mechanism includes a guide tube frame, the right side of the guide tube frame being fixedly connected to the left side of the winding device, a baffle plate being installed at the bottom of the guide tube frame, a guide plate being installed at the front side of the baffle plate, a transparent shell being installed at the bottom of the guide plate, an active roller being rotatably connected inside the transparent shell, a plurality of protruding plates being rotatably connected to the rear side of the active roller, a pressure roller being slidably connected to the rear side of the protruding plates, and a take-up shaft being installed at the bottom of the pressure roller.

[0006] As a further description of the above technical solution:

[0007] The winding equipment is internally connected to a rotating assembly, and a take-up shaft is rotatably connected to the left side of the rotating assembly.

[0018] As a further description of the above technical solution:

[0019] The top of the support platform is fixedly connected to a plurality of pads near the outer side, and each of the pads is fixedly connected to a guardrail.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, after the spinning thread passes through the anti-entanglement guide tube, it slides between the blocking plate and the guide plate under the obstruction of the guide plate. The gear at the end of the driving roller drives the pressure roller to rotate. The spinning thread slides between the pressure roller and the convex plate, and is finally wound into a spinning roll by the winding shaft. By repeatedly scraping the spinning thread with the guide plate and the convex plate, fiber debris is effectively removed, and the spinning thread is prevented from breaking due to the adhesion of debris.

[0022] 2. In this utility model, the lifting component adjusts the distance between the threading guide mechanism and the winding shaft through the lifting action. During the adjustment, the threading guide mechanism moves up and down along the guide device. Relying on the guiding effect of the guide device, the threading guide mechanism will not swing left and right or shake, thereby achieving the purpose of not affecting the normal use of the winding equipment when changing different sized bobbins.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 3 and Figure 4This utility model provides an embodiment of a yarn threading guide structure for a dual extrusion spinning and winding device, including a winding device 1, a yarn threading guide mechanism 2 fixedly connected to the left side of the winding device 1, the yarn threading guide mechanism 2 being used to guide the spinning yarn; the yarn threading guide mechanism 2 includes a guide tube frame 201, the right side of the guide tube frame 201 being fixedly connected to the left side of the winding device 1, a baffle plate 202 installed at the bottom of the guide tube frame 201, a guide plate 203 installed at the front side of the baffle plate 202, a transparent shell 204 installed at the bottom of the guide plate 203, an active roller 205 rotatably connected inside the transparent shell 204, a plurality of protruding plates 206 rotatably connected to the rear side of the active roller 205, a pressure roller 207 slidably connected to the rear side of the protruding plates 206, and a take-up shaft 208 installed at the bottom of the pressure roller 207;

[0032] Specifically, the spinning thread first passes through the guide tube frame 201, which is used to prevent entanglement. The guide tubes on the guide tube frame 201 can separate and guide the spinning thread, preventing multiple spinning threads from getting tangled from the source. Then, under the blocking and limiting of the guide plate 203, the spinning thread slides stably between the blocking plate 202 and the guide plate 203, further straightening the thread trajectory. After entering the transparent shell 204, the rotating drive roller 205 will push up the protrusion plate 206. At the same time, the gear at the end of the drive roller 205 will drive the pressure roller 207 to rotate. At this time, the spinning thread... The guide plate 203 and the convex plate 206 slide in the gap between the pressure roller 207 and the convex plate 206. With the cooperation of the two, the spinning thread is combed and tensioned. Finally, the spinning thread, which has undergone multiple treatments, is wound and wound by the take-up shaft 208 to form a regular spinning roll. Throughout the process, the guide plate 203 and the convex plate 206 scrape the spinning thread multiple times. This scraping action can remove the fiber debris attached to the surface of the spinning thread in time, effectively avoiding the problem of reduced spinning thread strength and breakage during production due to debris accumulation, and ensuring the continuity and stability of spinning production.

[0033] Reference Figure 2 and Figure 3 The inside of the wire winding device 1 is rotatably connected to a rotating assembly 3. A winding shaft 4 is rotatably connected to the left side of the rotating assembly 3. A lifting assembly 5 is fixedly connected to the top of the inner wall of the wire winding device 1. A guide device 6 is installed on the left side of the lifting assembly 5. A support frame 7 is fixedly connected to the bottom of the wire winding device 1. Multiple rollers 8 are fixedly connected to the right side of the support frame 7.

[0034] Specifically, when it is necessary to replace the bobbin with a different specification, the rotating component 3 is activated. The rotating component 3 drives the take-up shaft 208 and the take-up shaft 4 to rotate synchronously. By rotating, the angle and position of the two shafts are adjusted to provide sufficient operating space for replacing the bobbin. This allows the staff to quickly disassemble the old bobbin and install the new bobbin. After the bobbin replacement is completed, the lifting component 5 is activated. The lifting component 5 will drive the threading guide mechanism 2 to move up and down along the guide device 6. This adjusts the distance between the threading guide mechanism 2 and the take-up shaft to ensure that the threading angle and tension of the spinning thread are adapted to the new specification bobbin. At the same time, the support frame 7 is pushed. With the assistance of the bottom rollers 8, the support frame 7 can be moved smoothly to a suitable position that is compatible with the new bobbin, further optimizing the overall fit accuracy of the equipment. Throughout the adjustment process, the guide device 6 can strictly limit the movement trajectory of the threading guide mechanism 2, preventing it from swaying or shaking, and ensuring that the spinning thread always maintains a stable threading. Through this series of operations, the convenient replacement of bobbins of different sizes is realized. Moreover, during the replacement process, the various components of the equipment cooperate precisely and operate stably, without affecting the normal use of the winding equipment 1, thus ensuring the continuity of production.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A support platform 9 is installed on the outside of the filament winding equipment 1. A staircase 10 is fixedly connected to the rear side of the support platform 9. Multiple funnels 11 are fixedly connected to the top of the support platform 9. An extruder 12 is connected to each adjacent side of the multiple funnels 11. A spinning unit 13 is fixedly connected to the top of the support platform 9. A metering pump reducer 14 is rotatably connected to the top of the spinning unit 13. Multiple gaskets 15 are fixedly connected to the top of the support platform 9 near the outside. A guardrail 16 is fixedly connected to the top of each of the multiple gaskets 15.

[0036] Specifically, workers first climb onto the support platform 9. The guardrail 16 at the edge of the platform is fixed by the pads 15, which provides stable protection for the workers and avoids the risk of falling during operation. Then, the workers pour the raw materials required for production into the funnel 11. The raw materials are guided into the extruder 12 through the funnel 11. After the extruder 12 heats, melts and extrudes the raw materials, it is transported to the spinning unit 13. At the same time, the metering pump reducer 14 precisely controls the output and conveying speed of the spinning slurry to ensure that the concentration and flow rate of the spinning slurry are stable, providing a qualified raw material basis for the subsequent spinning process.

[0037] Working principle: As the spinning thread passes through the guide tube frame 201 to prevent the spinning threads from tangling, the guide tube on the guide tube frame 201 prevents the spinning threads from tangling. Then, under the obstruction of the guide plate 203, the spinning thread slides between the obstruction plate 202 and the guide plate 203. The drive roller 205 rotating inside the transparent shell 204 pushes up the convex plate 206. The gear at the end of the drive roller 205 drives the pressure roller 207 to rotate. Subsequently, the spinning thread slides between the pressure roller 207 and the convex plate 206. Finally, the spinning thread is wound up by the take-up shaft 208 to form a spinning roll. Because the guide plate 203 and the convex plate 206 scrape the spinning thread multiple times, the problem of the spinning thread breaking due to the adhesion of fiber debris during the production process is effectively avoided.

[0038] When it is necessary to replace the bobbins of different specifications, the rotating component 3 drives the take-up shaft 208 and the take-up shaft 4 to rotate, thereby facilitating the replacement of the bobbins on the take-up shaft 208 and the take-up shaft 4. Subsequently, the lifting component 5 adjusts the distance between the threading guide mechanism 2 and the take-up shaft. When adjusting the distance, it moves up and down along the guide device 6. Because the guide device 6 guides the threading guide mechanism 2, it will not swing left and right or shake, thus ensuring that the replacement of bobbins of different sizes does not affect the normal use of the winding equipment 1.
