Description

Technical Field

[0001] This utility model relates to the field of bandage production equipment technology, and in particular to a medical bandage winding device. Background Technology

[0002] In the production of medical bandages, the bandages are wound onto paper or plastic tubes, whose inner walls are relatively smooth. Currently, before winding the bandage, the paper or plastic tube needs to be fitted onto a rotating shaft. To ensure a smooth fit, one end of the shaft is suspended, which results in relatively poor stability during rotation. Furthermore, after the plastic tube is fitted onto the shaft, the tension during bandage winding can cause relative slippage between the plastic tube and the shaft, affecting winding stability. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a medical bandage winding device that can conveniently and quickly connect plastic tubes while maintaining stable operation of the plastic tubes during the winding process, thereby improving winding stability.

[0004] This utility model discloses a medical bandage winding device, including a base plate, a fixed upright plate at one end of the base plate, a bearing seat on the fixed upright plate, a rotating shaft inside the bearing seat, a limit ring on the rotating shaft, a slide rail at the other end of the base plate, a slide plate on the slide rail, a movable upright plate on the slide plate, a bearing seat on the movable upright plate, a main shaft inside the bearing seat, the central axis of the main shaft coincides with that of the rotating shaft, a limit ring on the main shaft, a power mechanism on the slide plate, the power mechanism driving the main shaft to rotate; and a telescopic mechanism on the base plate, the telescopic mechanism driving the slide plate to move on the slide rail.

[0005] To ensure a more stable and reliable connection of the plastic tube on the spindle, a cavity is provided at the end of the spindle furthest from the rotating shaft. This cavity extends into the spindle, while the end of the spindle closest to the rotating shaft is closed. At least three through slots are spaced apart on the circumferential sidewall of the spindle. These through slots are located on the side of the spindle closest to the rotating shaft and are situated within the cavity. The through slots penetrate the circumferential sidewall of the spindle, and their length is along the axial direction of the spindle. A slider is installed within each through slot, with its edge sliding in a sealing engagement with the through slot. The slider slides radially along the main shaft within the through groove. The thickness of the slider is greater than the thickness of the circumferential sidewall of the main shaft. A sealing ring is formed by extending the slider end outward within the cavity. A sealing rotating ring is provided at the cavity end of the main shaft away from the rotating shaft. A high-pressure air pipe is provided within the sealing rotating ring. The high-pressure air pipe extends into the cavity and does not contact the main shaft. The high-pressure air pipe and the main shaft are sealed and connected by the sealing rotating ring, and the two are rotatably connected. A through hole is provided on the high-pressure air pipe near the through groove.

[0006] To ensure that the spindle and the rotating shaft operate synchronously and stably, a rectangular protrusion is provided at the end of the rotating shaft near the spindle, and a rectangular groove is provided at the end of the spindle near the rotating shaft. The rectangular groove and the rectangular protrusion are fitted together.

[0007] The power mechanism is a drive motor, with a driven pulley on the main shaft. The drive motor is fixed on the slide plate, and a driving pulley is on the output shaft of the drive motor. The driving pulley and the driven pulley are connected by belt drive.

[0008] The telescopic mechanism is a cylinder, which is fixed to the base plate. The telescopic end of the cylinder is fixedly connected to the slide plate, and the telescopic direction of the cylinder is consistent with the movement direction of the slide plate on the slide rail.

[0009] To facilitate the quick removal of the plastic tube from the main shaft after the medical bandage is wound, a feed plate is provided on the base plate between the slide rail and the fixed upright plate. The feed plate has a vertically downward U-shaped groove that runs through the thickness direction of the feed plate. The main shaft passes through the U-shaped groove, and the width of the U-shaped groove is greater than the outer diameter of the limiting retaining ring.

[0010] The medical bandage winding device of this invention moves the main shaft by moving the sliding plate and the movable upright plate. This allows for quick connection of the plastic tube during connection by moving the main shaft. Air pressure is used to push the slider outward to fix the plastic tube on the main shaft, improving stability and making the bandage winding process more reliable. Attached Figure Description

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] Example 1:

[0019] like Figures 1-6 As shown, this utility model discloses a medical bandage winding device, including a base plate 1, a fixed upright plate 2 at one end of the base plate 1, a bearing seat 3 on the fixed upright plate 2, a rotating shaft 4 inside the bearing seat 3, a limit ring 5 on the rotating shaft 4, a slide rail 7 at the other end of the base plate 1, a slide plate 8 on the slide rail 7, a movable upright plate 9 on the slide plate 8, a bearing seat 3 on the movable upright plate 9, a main shaft 10 inside the bearing seat 3, the main shaft 10 coinciding with the central axis of the rotating shaft 4, a limit ring 5 on the main shaft 10, a power mechanism on the slide plate 8 driving the main shaft 10 to rotate, and a telescopic mechanism on the base plate 1 driving the slide plate 8 to move on the slide rail 7.

[0020] A rotating shaft 4 is mounted on a bearing seat 3 on the fixed upright plate 2. The rotating shaft 4 and bearing seat 3 are freely rotatable, but the rotating shaft 4 cannot undergo relative axial displacement. The movable upright plate 9 can reciprocate on the slide rail 7 via a sliding plate 8 and is positioned by a telescopic mechanism according to actual needs. In actual use, the telescopic mechanism first moves the main shaft 10 away from the rotating shaft 4, creating a gap between the rotating shaft 4 and the main shaft 10, allowing the plastic tube to pass through. One end of the plastic tube is then inserted into the rotating shaft 4 and pressed against the limiting ring 5. At this point, the telescopic mechanism is controlled to move the main shaft 10 closer to the rotating shaft 4 and insert it into the plastic tube. Finally, the main shaft 10 and the rotating shaft 4 come into contact, and the limiting ring 5 on the main shaft 10 abuts against the end of the plastic tube, achieving the connection and fixation of the plastic tube. The operation is simple and convenient. During winding, the power mechanism drives the main shaft 10 to rotate, which in turn drives the entire plastic tube to rotate. The operation is stable and reliable. Furthermore, during operation, the rotating shaft 4 is connected to the main shaft 10, and both ends are supported by the fixed vertical plate 2 and the shaft seat 3 on the movable vertical plate 9, respectively, ensuring high stability. When unloading, simply remove the main shaft 10 from the rotating shaft 4 to detach the plastic tube from the main shaft 10, which is simple and convenient.

[0021] A cavity 24 is provided at the end of the main shaft 10 away from the rotating shaft 4. The cavity 24 extends into the interior of the main shaft 10. The end of the main shaft 10 near the rotating shaft 4 is closed. Four through slots are spaced apart on the circumferential sidewall of the main shaft 10. The through slots are located on the side of the main shaft 10 near the rotating shaft 4 of the limiting ring 5, and are located within the cavity 24. The through slots penetrate the circumferential sidewall of the main shaft 10, and their length direction is along the axial direction of the main shaft 10. A slider 11 is provided in each through slot. The edge of the slider 11 is slidably connected to the through slot in a sealing fit. The slider 11 moves radially along the main shaft 10 within the through slot. The slider 11 is thicker than the circumferential sidewall of the main shaft 10. The end of the slider 11 in the cavity 24 extends outward to form a sealing ring 22. A sealing rotating ring 16 is provided at the end of the cavity 24 of the main shaft 10 away from the rotating shaft 4. A high-pressure air pipe 17 is provided in the sealing rotating ring 16. The high-pressure air pipe 17 extends into the cavity 24 and does not contact the main shaft 10. The high-pressure air pipe 17 and the main shaft 10 are sealed and connected by the sealing rotating ring 16 and are rotatably connected. A through hole 21 is provided on the high-pressure air pipe 17 near the through groove.

[0022] To ensure a secure and stable connection of the plastic tube to the main shaft 10, and to simplify the material feeding process, a hollow cavity 24 is formed at one end of the main shaft 10. A through groove is provided on the circumferential sidewall of the main shaft 10, and the slider 11 is positioned within this groove, forming a sliding and sealed connection. The end of the cavity 24 is sealed via a sealing ring 16 and a high-pressure air pipe 17 passes through it. The cavity 24 forms a closed chamber. When high-pressure air is introduced into the high-pressure air pipe 17, the increased air pressure within the cavity 24 pushes the slider 11 outward, thus securing the plastic tube against its inner wall and ensuring a secure and stable connection. While the main shaft 10 rotates, the high-pressure air pipe 17 is rotatably connected to the main shaft 10 via the sealing ring 16. Therefore, when the high-pressure air pipe 17 is connected to the air source through a pipe, it remains stationary due to the influence of the pipe. Of course, the high-pressure air pipe 17 can be connected to the high-pressure air source and the negative pressure mechanism via a pipeline, and can be switched via a control valve. When it is necessary to fix the plastic tube, the high-pressure air source is introduced into the cavity 24. When the medical bandage is finished and needs to be unloaded, it can be switched to the negative pressure mechanism, allowing the high-pressure air pipe 17 to extract the air from the cavity 24, creating a negative pressure in the cavity 24, thereby drawing the slider 11 into the cavity 24, causing the slider 11 to separate from the plastic tube, making it easy to detach the plastic tube from the main shaft 10. This method is simple and convenient to operate, greatly improving operating efficiency. A sealing ring 22 is set at the end of the slider 11 in the cavity 24 to further improve its sealing effect and also to prevent the slider 11 from being directly ejected from the through groove, resulting in higher safety and stability. Generally, four through grooves are selected, evenly spaced on the circumferential sidewall of the main shaft 10, and the length of the through grooves can be selected according to actual needs. The end of the high-pressure air tube 17 extends to the end of the cavity 24, but there is a gap between it and the main shaft 10 at the end of the cavity 24, so the rotation of the main shaft 10 does not affect the stationarity of the high-pressure air tube 17. The through hole 21 can be set on the air tube near the end of the slider 11, so that the response is faster.

[0023] A rectangular protrusion 6 is provided at the end of the rotating shaft 4 near the main shaft 10, and a rectangular groove 20 is provided at the end of the main shaft 10 near the rotating shaft 4. The rectangular groove 20 and the rectangular protrusion 6 are fitted together for insertion. To ensure stable and synchronous rotation of the main shaft 10 and the rotating shaft 4, the rectangular protrusion 6 is provided on the rotating shaft 4, and the rectangular groove 20 is provided on the main shaft 10. This fits together for insertion, achieving synchronization during rotation. Furthermore, under normal circumstances, the length of the plastic tube is equal to the distance between the two limiting rings 5 ​​after the rotating shaft 4 and the main shaft 10 are connected. However, the length of the plastic tube often has errors. By fitting the rectangular groove 20 and the rectangular protrusion 6 together, the insertion depth of both is within the allowable error range of the plastic tube, thus achieving a stable connection of the plastic tube.

[0024] The power mechanism is a drive motor 12, with a driven pulley 14 mounted on the main shaft 10. The drive motor 12 is fixed to the slide plate 8, and a drive pulley 13 is mounted on the output shaft of the drive motor 12. The drive pulley 13 and the driven pulley 14 are connected by a belt 15. The belt 15 transmission ensures rapid and stable power transmission, allowing the main shaft 10 to operate stably and making the winding process smoother.

[0025] The telescopic mechanism is a cylinder 23, which is fixed to the base plate 1. The telescopic end of the cylinder 23 is fixedly connected to the slide plate 8, and the telescopic direction of the cylinder 23 is consistent with the movement direction of the slide plate 8 on the slide rail 7. The cylinder 23 can respond quickly and drive the slide plate 8 to move, greatly improving efficiency.

[0026] A feeding plate 18 is provided on the base plate 1 between the slide rail 7 and the fixed upright plate 2. A vertically downward U-shaped groove 19 is provided on the feeding plate 18. The U-shaped groove 19 extends through the thickness direction of the feeding plate 18. The main shaft 10 passes through the U-shaped groove 19. The width of the U-shaped groove 19 is greater than the outer diameter of the limiting retaining ring 5.

[0027] During material feeding, after the main shaft 10 separates from the rotating shaft 4, the plastic tube wrapped with medical bandage is often fitted onto the main shaft 10. Therefore, the operator needs to pull it off the main shaft 10. Although the connection between the two is a clearance fit, the process still requires considerable physical effort. To allow the operator to quickly remove the medical bandage from the main shaft 10, a feeding plate 18 is provided. The U-shaped groove 19 on the feeding plate 18 allows the main shaft 10 and the limiting baffle to pass through, so it does not affect the assembly of the plastic tube. However, when the medical bandage is wrapped around the plastic tube, its overall diameter increases, exceeding the width of the U-shaped groove 19. Therefore, during material feeding, as the main shaft 10 moves away from the rotating shaft 4, the main shaft 10 and the limiting baffle 5 pass through the U-shaped groove 19, but the plastic tube wrapped with medical bandage cannot pass through and is blocked, thus automatically being pulled off the main shaft 10. The operator only needs to feed the material, which is simple, convenient, and greatly improves operational efficiency.
