[0031] In order to make the purpose, technical solutions and beneficial effects of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for the purpose of explaining this application and are not intended to limit this application.

[0032] As mentioned in the background, medical catheters such as nasal oxygen cannulas require long tubes to be coiled and automatically packaged after production for easy packaging and transportation. Currently, traditional coiling of long tubes requires manual or automated processes. Manual coiling is inefficient and labor-intensive, while automated coil sealing machines are expensive and suitable for large-scale production, but not for small or medium-sized batches.

[0033] In response to the above technical problems, the present invention provides a long conduit coil device, comprising a coil rack, a coil rotation assembly 400, a lifting mechanism, and a rotation mechanism arranged on the coil rack.

[0034] For details, see Figure 1 The coil frame includes a lifting cylinder fixing plate 110, a fixed bottom plate 120, and a pressure plate bottom plate 130. The lifting cylinder fixing plate 110, the fixed bottom plate 120, and the pressure plate bottom plate 130 are arranged in order from bottom to top, and the lifting cylinder fixing plate 110 and the fixed bottom plate 120, as well as the fixed top plate and the pressure plate bottom plate 130, are connected by a plurality of fixed columns 140.

[0035] The jacking mechanism includes a jacking cylinder 210 and a jacking shaft 240 driven by the jacking cylinder 210. The jacking cylinder 210 is fixedly mounted on the jacking cylinder fixing plate 110, and is used to drive the jacking shaft 240 to rise and fall, so as to lift the coil rotation assembly 400. In some embodiments, the jacking mechanism also includes a lower jacking plate 230 and a cylinder connecting block 220, wherein the cylinder connecting block 220 is fixedly connected to the piston rod of the jacking cylinder 210, the cylinder connecting block 220 is connected to the lower jacking plate 230, the bottom end of the jacking shaft 240 is fixedly connected to the lower jacking plate 230, and the top end of the jacking shaft 240 passes through the fixed bottom plate 120. Preferably, the cylinder connecting block 220 and the lower jacking plate 230 are movably connected. The cylinder connecting block 220 and the lower jacking plate 230 are movably connected to facilitate disassembly and assembly. Furthermore, a T-slot 231 is provided on the lower jacking plate 230 , and the cylinder connecting block 220 is embedded in the T-slot 231 , thereby movably connecting the cylinder connecting block 220 and the lower jacking plate 230 .

[0036] Because the cylinder connection block 220 and the lower jacking plate 230 are flexibly connected, in some embodiments, the jacking mechanism further includes a pair of jacking guide shafts 250 to enhance jacking stability. These jacking guide shafts 250 pass through the jacking cylinder fixing plate 110 and are connected to the ends of the lower jacking plate 230. The jacking guide shafts 250 guide the movement of the lower jacking plate 230, ensuring more stable lifting and lowering of the lower jacking plate 230. Preferably, a linear bearing 260 is further disposed between the jacking guide shafts 250 and the jacking cylinder fixing plate 110.

[0037] See Figure 2 The rotating mechanism includes a rotating shaft 320, a synchronous belt mechanism, a rotating base 340, and a suction tube tray 360. The rotating shaft 320 has a through hole inside, which fits over the outer surface of the lifting shaft 240. There is a gap between the lifting shaft 240 and the surface of the lifting shaft 240, so that the two do not interfere with each other's movement. The top end of the rotating shaft 320 passes through the fixed base plate 120, and a seated bearing 330 is installed between it and the fixed base plate 120.

[0038] The rotating shaft 320 is driven to rotate by a synchronous belt mechanism. Specifically, the synchronous belt mechanism includes a drive motor, a first synchronous pulley 313, a second synchronous pulley 314, and a synchronous belt 315. The drive motor is mounted on the lifting cylinder fixing plate 110, and the first synchronous pulley 313 is mounted on the output spindle of the drive motor. The second synchronous pulley 314 is mounted on the rotating shaft 320, and the rotating shaft 320 and the second synchronous pulley 314 are connected by a key. The synchronous belt 315 is mounted on the first synchronous pulley 313 and the second synchronous pulley 314. Preferably, the drive motor includes a servo motor 311 and a planetary reducer 312. The planetary reducer 312 is mounted on the spindle of the servo motor 311, and the first synchronous pulley 313 is mounted on the output spindle of the planetary reducer 312.

[0039] The rotating base 340 is mounted on top of the rotating shaft 320 and is equipped with multiple rotating columns 350. Suction tube trays 360 are fixed to the tops of the rotating columns 350. In some embodiments, there are four rotating columns 350, evenly distributed on the rotating base 340. The platen bottom plate 130 has circular holes that match the suction tube trays 360. The suction tube trays 360 are placed in the circular holes and fixedly connected to the tops of the four rotating columns 350. Therefore, the rotating shaft 320 is driven by a synchronous belt mechanism to rotate, which in turn drives the rotating disk 420 and the suction tube trays 360 to rotate.

[0040] See Figure 3-4The coil rotating assembly 400 includes a transmission support plate 410, a rotating disk 420, and a plurality of winding blocks 430. Specifically, the transmission support plate 410 is connected to a portion of the rotating column 350, and the rotating disk 420 is fixed to the transmission support plate 410. Therefore, the transmission support plate 410 and the rotating disk 420 can be driven by the rotating column 350 to rotate, and can also perform lifting movements at the same time. In some embodiments, the transmission support plate 410 is elliptical, and a through-hole 411 is provided at both ends thereof, so that the transmission support plate 410 can be connected to a pair of rotating columns 350 located at opposite corners through the through-hole 411. Preferably, a sliding bearing is provided between the transmission support plate 410 and the rotating column 350. A through-hole 412 is provided at the center of the transmission support plate 410, and the top of the lifting shaft 240 passes through the through-hole 412, which abuts against the bottom of the rotating disk 420. Therefore, by lifting the rotating disk 420 above through the lifting shaft 240, the transmission support plate 410 and the rotating disk 420 can be driven to perform lifting movements.

[0041] See Figure 3-5 The winding blocks 430 are fixed to the rotating disk 420, with multiple winding blocks evenly spaced around the center of the rotating disk 420. Furthermore, the suction tube tray 360 is provided with a shaped hole 361, through which the winding blocks 430 can pass during the raising and lowering process. As the rotating disk 420 rotates, the long tube rotates around the winding blocks 430 and is coiled. Preferably, the surface of the winding blocks 430 is provided with an arcuate groove 431 that mates with the long tube to facilitate coiling.

[0042] In a preferred embodiment, four radially extending strip-shaped mounting slots 421 are evenly spaced on the rotating disk 420. Four winding blocks 430 are mounted in each of these strip-shaped mounting slots 421. These strip-shaped mounting slots 421 facilitate adjustment of the position of the winding blocks 430. Furthermore, in a preferred embodiment, the winding blocks 430 are fan-shaped, with arcuate grooves 431 defined on the arcuate surface of the winding blocks 430. Furthermore, one of the winding blocks 430 is provided with a clamping portion 432 to grip the connector of a long conduit, thereby facilitating subsequent coiling.

[0043] In the present invention, the rotating disk 420 is lifted by a lifting mechanism, allowing the winding block 430 on the rotating disk 420 to pass through the special-shaped hole 361 in the suction tube tray 360 and emerge. The connector of the long catheter is then clamped by the clamping portion 432 of the winding block 430. The rotating mechanism is then activated, driving the suction tube tray 360 and the rotating disk 420 to rotate synchronously, thereby winding the long catheter around the winding block 430 and gradually winding it into a disc. After the coiling is completed, the rotating disk 420 is lowered by the lifting mechanism, allowing the winding block 430 to be separated from the disc-shaped catheter, allowing the disc-shaped catheter to be removed.

[0044] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
