Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe forming technology, specifically a copper wire winding mechanism for corrugated pipe forming. Background Technology

[0002] As a key component in medical devices, corrugated breathing tubes require heating functionality in certain applications, particularly those needing to prevent condensation or maintain a constant gas temperature. This is typically achieved by embedding conductive materials, such as copper wires, within the tube wall. These wires generate heat when energized, keeping the inside of the breathing tube warm, preventing condensation, and improving patient comfort. Traditional manufacturing processes for corrugated breathing tubes primarily focus on the extrusion molding of the basic plastic tube. While this method meets general medical needs, it is insufficient for advanced applications requiring heating. Furthermore, the winding of copper wires in most breathing tubes relies on manual operation, which is not only inefficient but also makes it difficult to ensure consistent product quality. Issues such as copper wire misalignment and uneven winding can occur, affecting the performance of the final product. Utility Model Content

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] Please see Figures 1 to 10 This utility model provides a technical solution: a copper wire winding mechanism for corrugated pipe forming, comprising: a water collection tank 1; a cooling water tank 2 fixedly installed on the top of the water collection tank 1 by bolts; a top support frame 4 fixedly installed inside the cooling water tank 2 by bolts, the inner side of the cooling water tank 2 being provided with a guide portion that cooperates with the top support frame 4; a support body 8 placed on one side of the water collection tank 1, a strip extrusion device 9 being provided on the support body 8, and an extruder 10 being provided on one side of the water collection tank 1; a copper wire feeding roller 29 being disposed above the water collection tank 1; and a support frame 11 being disposed on one side of the support body 8, the inside of which is provided with a belt drive 12. A fixed support column 14 is bolted to the top of the support frame 11; a rotating main shaft 34 is rotatably mounted inside the fixed support column 14, and a drive gear 18 is fixedly mounted on the outside of the rotating main shaft 34; six rotating secondary shafts 16 are rotatably mounted inside the fixed support column 14, and driven gears 17 are fixedly connected to the outside of each of the six rotating secondary shafts 16. The driven gears 17 mesh with the drive gear 18; the output shaft of the belt drive 12 is fixedly connected to the rotating main shaft 34; a rotating flexible rod 21 is fixedly connected to one end of the rotating secondary shaft 16; a cooling column 15 is fixedly connected to one end of the fixed support column 14, and multiple external movable grooves 25 that cooperate with the rotating flexible rod 21 are opened on the outside of the cooling column 15.

[0032] It should be noted that in this embodiment, the integrated continuous production process of the corrugated breather tube's basic tube body extrusion, copper wire spiral winding, outer texture coating, and overall cooling and shaping is achieved through the coordinated operation of various components. The strip extrusion equipment 9 heats and melts the plastic raw material and extrudes it through a circular die to form a continuous hollow cylindrical basic tube body. This tube body enters the cooling water tank 2 for preliminary cooling and shaping, providing a stable tube skeleton for subsequent processes. The copper wire coil on the copper wire feeding equipment 28 is smoothly released under the action of a constant tension controller and conveyed to the copper wire feeding roller 29 through the guide wheel group. The copper wire feeding roller 29 consists of a pair of adjustable-pressure rubber rollers and steel rollers, which precisely control the feeding speed and tension of the copper wire to ensure stable and continuous copper wire feeding. The wire is fed to the winding area. The first manual linear module 30 on the top of the support 8 and the second manual linear module 31 mounted on its slide constitute an XY two-dimensional adjustment platform. By rotating the handwheel, the ball screw and linear guide rail drive the precise displacement of the moving slide, thereby adjusting the spatial position of the adjusting slide plate 33 and cylinder 32 mounted on it. This allows the copper wire feeding roller 29 to be flexibly fine-tuned in both horizontal and vertical directions, adapting to the copper wire introduction angle and contact point position under different pipe diameters, ensuring accurate winding start point and uniform tension. When the base pipe moves forward, it passes through the annular conveying channel formed by the rotating soft rods 21 driven by six rotating secondary shafts 16. One end of these rotating soft rods is connected to the driven gear 17, and the other end... One end is embedded in the outer movable groove 25 outside the cooling column 15 and can rotate freely. Each rotating flexible rod has a threaded conveying groove machined on its surface. When the servo motor 13 is started, the power is transmitted to the rotating main shaft 34 via the belt drive 12, and then the six driven gears 17 are driven to rotate synchronously through the meshing of the drive gear 18, so that the six rotating flexible rods rotate at a uniform speed around the center of the tube. During the rotation, the threaded conveying groove generates an axial thrust on the tube, causing it to move forward, and also forces the tube to rotate itself, forming a spiral motion trajectory. At this time, the copper wire from the copper wire feeding roller 29 is evenly spirally wound on the outer surface of the tube at a set pitch. After the winding is completed, the tube continues to move forward and enters the working area of ​​the extruder 10. The extruder delivers another stream of molten plastic through the annular... The co-extrusion die covers the outer layer of the tube already wound with copper wire. At the same time, the corrugated forming cavity inside the die directly extrudes the periodic undulating outer wall texture. The newly molten plastic completely covers the copper wire and fuses with it, playing a role in fixing, protecting and enhancing mechanical strength. During the entire conveying and winding process, the cooling column 15 plays a key heat dissipation function. Cooling water is injected into the inner water passage 23 through the water inlet pipe 22 and then distributed to multiple U-shaped water passages to absorb heat. It then flows into the outer water passage ring 19 through the pipe and finally is discharged to the collection tank 1 through the bottom drain pipe 20, achieving effective cooling of the extruded material. At the same time, the No. 1 cooling water nozzle 26 and the No. 2 cooling water nozzle 27 set above the cooling water tank 2 spray and cool the newly formed composite pipe, accelerating the shaping process.The cooling water tank 2 is guided by a guide section consisting of mounting base 5, L-shaped mounting bracket 6, and guide seat 7, which works in conjunction with the top support frame 4 to form a stable guiding channel. This prevents the pipe from sagging or swaying due to its own weight or uneven traction, ensuring smooth operation. The top of the collection tank 1 is equipped with a filter screen 3 to intercept impurities and debris carried in the cooling water, maintaining water quality cleanliness. The entire system uses a servo motor to precisely control the speed, combined with the flexible adjustment capability of a manual linear module, to achieve rapid switching and high-precision matching of copper wire winding parameters in the production of corrugated pipes of different specifications, ultimately producing composite corrugated pipe products.

[0033] In one embodiment, such as Figures 1 to 10 As shown, an outer water ring 19 is fixedly connected to the outside of the cooling column 15, and a rotating flexible rod 21 is movably connected to the outer water ring 19. A bottom drain pipe 20 is fixedly connected to the bottom of the outer water ring 19, and a water inlet pipe 22 is fixedly connected to the top of the cooling column 15. An inner water cavity 23 is opened inside the cooling column 15, and multiple U-shaped water cavities 24 are opened inside the inner water cavity 23. The U-shaped water cavities 24 are connected to the inner water cavity 23, and the U-shaped water cavities 24 are connected to the outer water ring 19 through pipes. A threaded conveying groove is opened on the outside of the rotating flexible rod 21.

[0034] It should be noted that in this embodiment, cooling water enters the inner water passage 23 through the water inlet pipe 22, flows through the U-shaped water passage 24 to form sufficient heat exchange, carries away the heat of the cooling column 15, and cools the formed corrugated pipe. The cooling water enters the outer water passage ring 19 through the pipe, discharges the cooling water, and is collected through the collection tank 1.

[0035] In one embodiment, such as Figures 1 to 10 As shown, the guide part includes a mounting base 5, an L-shaped mounting bracket 6, and a guide seat 7. Four mounting bases 5 are bolted to the inner side of the cooling water tank 2. An L-shaped mounting bracket 6 is bolted to the inner side of the mounting base 5. A guide seat 7 that mates with the top support bracket 4 is bolted to the bottom of the L-shaped mounting bracket 6.

[0036] It should be noted that, in this embodiment, by setting the mounting base 5, the L-shaped mounting bracket 6 and the guide seat 7, the corrugated breathing tube with copper wire can be guided and stably supported by the top support frame 4.

[0037] In one embodiment, such as Figures 1 to 10 As shown, a first manual linear module 30 is provided on the top of the support body 8. A second manual linear module 31 is installed on the moving slide of the first manual linear module 30. An adjusting slide plate 33 is installed on the moving slide of the second manual linear module 31. A cylinder 32 is installed on the top of the adjusting slide plate 33 by bolts. The output end of the cylinder 32 is fixedly connected to the copper wire feeding roller 29.

[0038] It should be noted that in this embodiment, a two-dimensional adjustment platform is constructed using a double-layer manual linear module, which, in conjunction with the cylinder 32, enables precise position adjustment of the copper wire feeding roller 29 in the horizontal and vertical directions. This allows the copper wire feeding angle and tension to be flexibly adjusted according to different corrugated pipe specifications, ensuring that the copper wire is wound evenly and stably on the pipe surface, avoiding misalignment, overlap, or loosening.

[0039] In one embodiment, such as Figures 1 to 10 As shown, a copper wire feeding device 28 that cooperates with the copper wire feeding roller 29 is provided on one side of the support body 8.

[0040] It should be noted that in this embodiment, a dedicated copper wire feeding device 28 and a copper wire feeding roller 29 are set up to work together to achieve a continuous and stable supply of copper wire, which is suitable for large-scale corrugated pipe production scenarios.

[0041] In one embodiment, such as Figures 1 to 10 As shown, a filter screen 3 is symmetrically arranged on the top of the water collection tank 1, a servo motor 13 is arranged on one side of the support frame 11, the output end of the servo motor 13 is fixedly connected to the input shaft of the belt drive 12, a plurality of first cooling water nozzles 26 are arranged above the cooling water tank 2, and a plurality of second cooling water nozzles 27 are arranged above the cooling water tank 2.

[0042] It should be noted that in this embodiment, the filter screen 3 can effectively intercept impurities and debris carried in the cooling water. The servo motor 13 drives the belt drive 12 to provide precise and controllable power output, ensuring that the rotation speed of the main shaft 34 and the secondary shaft 16 is stable and synchronized. The addition of a first cooling water nozzle 26 and a second cooling water nozzle 27 enables spray cooling of the corrugated pipe during molding, thereby accelerating the molding speed.
