Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical tape processing technology, and in particular to a core clamping device for winding medical tape. Background Technology
[0002] In existing technologies, the core of medical tape needs to be clamped and fixed during the winding process. Currently, many methods use mechanical structures to manually adjust the tension to clamp the core, which is inefficient and affects production efficiency. Other methods use pneumatic or electric cylinders to clamp the core, but because the turntable needs to rotate, the electric or pneumatic cylinders also need to rotate with the turntable to stably wind the tape. These cylinders require external connections to wires and air pipes, so brushes and rotary joints are used to transmit current and airflow to achieve rotation. However, this structure has a relatively short lifespan, frequently malfunctions, and requires frequent replacement and maintenance, reducing production efficiency and increasing production costs. Utility Model Content
[0003] To address the aforementioned technical deficiencies, this invention provides a core clamping device for medical tape winding, which can automatically clamp and release the core, thereby improving processing efficiency.

[0014] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following describes in detail the specific embodiments, structures, features and their effects according to the present utility model in combination with the attached drawings and preferred embodiments.
[0015] Embodiment 1:
[0016] As Figures 1-5 As shown, this utility model discloses a core clamping device for medical tape winding, including a frame 1, a circular turntable 2 on the frame 1, a vertically downward rotating shaft 6 on the lower surface of the turntable 2, the rotating shaft 6 being rotatably connected to the frame 1, four slide rails 3 spaced radially on the turntable 2, an arc-shaped pressure plate 4 on the slide rails 3, a cylindrical concave slide rail 16 vertically arranged at the center of the turntable 2, a guide post 5 arranged within the concave slide rail 16, the upper end of the guide post 5 extending above the arc-shaped pressure plate 4, and a tension spring 17 arranged within the concave slide rail 16 below the guide post 5, the lower end of the tension spring 17 being fixed to the bottom of the concave slide rail 16. The upper end of the tension spring 17 is fixedly connected to the end of the guide post 5. In its natural state, the radius of the guide post 5 exposed outside the concave slide 16 gradually decreases from top to bottom. A horizontal push rod 13 is provided on the inner side of each arc-shaped pressure plate 4, and the push rod 13 abuts against the side wall of the guide post 5. A power mechanism is provided on the frame 1, and the power mechanism is connected to the rotating shaft 6. A vertical through hole 18 is provided in the center of the rotating shaft 6. The through hole 18 passes through the turntable 2 and communicates with the concave slide 16. A vertically upward cylinder 8 is provided on the frame 1 below the rotating shaft 6. The telescopic end of the cylinder 8 extends into the concave slide 16 through the through hole 18 and drives the guide post 5 to rise and fall.
[0017] The frame 1 serves as the carrier for all components, and its specific structural form is not limited. The turntable 2 is rotatably mounted on the frame 1. The turntable 2 is cylindrical with a circular horizontal cross-section. A rotating shaft 6 is located at the center of the bottom of the turntable 2, and the rotating shaft 6 is integral with the turntable 2. A bearing 14 is installed between the rotating shaft 6 and the frame 1. The rotating shaft 6 is driven by a power mechanism, causing it to rotate together with the turntable 2, thereby enabling the winding of medical tape onto the tube core fixed on the turntable 2. To achieve tension clamping of the tube core, four slide rails 3 are installed on the turntable 2. The slide rails 3 are arranged radially, and the four slide rails 3 are equally spaced, meaning that adjacent slide rails 3 form a 90° angle. An arc-shaped pressure plate 4 is installed on each slide rail 3, and the arc-shaped pressure plate 4 is slidably connected to the slide rail 3. Each arc-shaped pressure plate 4 is equipped with a push rod 13, which abuts against the side wall of the guide post 5. Since the guide post 5 is wider at the top and narrower at the bottom, when the guide post 5 moves downward, it pushes the corresponding arc-shaped pressure plate 4 outward through the push rod 13. At this time, the tube core is sleeved on the outside of the arc-shaped pressure plate 4, and the four arc-shaped pressure plates 4 abut against the inner wall of the tube core, tightening it and maintaining a clamped state. After the medical tape is wound, the guide post 5 can be moved upward, and the push rod 13 will lack support. The arc-shaped pressure plate 4 can then move inward, detaching the arc-shaped pressure plate 4 from the inner wall of the tube core, thus easily removing the tube core and medical tape, making the operation convenient.
[0018] Of course, a vertically concave slideway 16 is arranged at the center of the turntable 2. The lower end of the guide post 5 is slidably connected with the concave slideway 16 in a matching manner. A tension spring 17 is arranged in the concave slideway 16. Therefore, in the natural state, the tension spring 17 pulls the guide post 5 downward. At this time, the upper end of the guide post 5 is butted against the ejector rod 13, and the arc-shaped pressing plate 4 is located on the relatively outer side, and the tube core is in a tensioned state. A through hole 18 is arranged at the center of the rotating shaft 6 and extends into the concave slideway 16. An air cylinder 8 is arranged at the bottom. The telescopic rod of the air cylinder 8 extends into the concave slideway 16 and can support the guide post 5, pushing the guide post 5 upward against the pulling force of the spring and its own gravity, so that the ejector rod 13 is butted against the middle and lower end of the guide post 5, that is, the support for the ejector rod 13 is removed, and the arc-shaped pressing plate 4 can be pushed inward to realize the release of the tube core.
[0019] During the working process of this form, when the air cylinder 8 extends, it带动 the guide post 5 to move upward. At this time, the four arc-shaped pressing plates 4 can be pushed inward, and the outer diameter formed by the arc-shaped pressing plates 4 is reduced. At this time, the tube core is sleeved outside the four arc-shaped pressing plates 4. Then the air cylinder 8 contracts, removing the thrust on the guide post 5. Then the guide post 5 moves downward under the action of the tension spring 17 and its own gravity. During the downward movement, the side wall of the guide post 5 pushes the ejector rod 13 outward, thereby带动 the arc-shaped pressing plate 4 to move outward and tighten the tube core to maintain stable clamping. For the release process, the air cylinder 8 just needs to extend. The above process can实现 the automatic tensioning and release of the tube core, with high efficiency. Moreover, after tensioning, when the air cylinder 8 contracts, it is separated from the guide post 5, and the two are not connected. Therefore, during the winding process of the medical tape, when the turntable 2 and the guide post 5 rotate synchronously, there is no interference from external components, and the equipment runs stably and reliably.
[0020] An inner groove 12 is arranged on the side wall of the guide post 5. The distance between the inner groove 12 and the corresponding side wall of the guide post 5 is the same. The number and position of the inner grooves 12 correspond to the ejector rod 13. The horizontal cross-section of the inner groove 12 is in the shape of a "convex". The end of the ejector rod 13 extends into the inner groove 12. Short shafts extend outward on both sides of the end of the ejector rod 13 inside the inner groove 12. A pressing wheel 15 is arranged on each short shaft. The distance between the outermost sides of the two pressing wheels 15 is greater than the size of the opening of the inner groove 12 on the side wall of the guide post 5.
[0021] To allow the arc-shaped pressure plate 4 to automatically retract during the upward movement of the guide column 5, an inner groove 12 is provided on the guide column 5. The cross-section of the inner groove 12 is convex, and the push rod 13 extends into the inner groove. A short shaft and pressure roller 15 extend outward from the end of the push rod 13, thus confining the pressure roller 15 within the inner groove 12. During the downward movement of the guide column 5, the inner sidewall of the inner groove 12 abuts against the pressure roller 15, pushing the push rod 13 outward. Conversely, when the cylinder 8 extends to push the guide column 5 upward, the outer sidewall of the inner groove 12 abuts against the pressure roller 15, pulling the push rod 13 inward. This allows the lifting and lowering of the guide column 5 to be synchronized with the reciprocating movement of the arc-shaped pressure plate 4, further enhancing automation.
[0022] Each slide rail 3 on the turntable 2 consists of two spaced-apart convex rails, which are parallel to each other. The parallel arrangement of the two convex rails on the slide rail 3 makes the reciprocating movement of the arc-shaped pressure plate 4 more stable.
[0023] The power mechanism includes a drive motor 7 mounted on the frame 1. The output shaft of the drive motor 7 is vertically upward. A drive pulley 9 is mounted on the output shaft of the drive motor 7, and a driven pulley 10 is mounted on the rotating shaft 6. The drive pulley 9 and the driven pulley 10 are connected by a belt 11.
[0024] The drive motor 7 drives the rotating shaft 6 for transmission, which is stable and reliable.
