[0014] Please see Figure 1-4 This utility model provides a technical solution: an ink filling device for pen manufacturing, including an ink connector 1, an ink cavity 2 inside the ink connector 1, an ink cartridge 4 on one side of the top of the ink connector 1, two sides of the top of the ink cavity 2 extending to the two sides of the top of the ink connector 1 respectively, a limiting ring gasket 6 fixedly connected above the other side of the top of the ink connector 1 corresponding to the other side of the top of the ink cavity 2, an annular protective seat 7 fixedly connected to the outer side of the limiting ring gasket 6 corresponding to the top of the ink connector 1, a pen body 8 on the top of the annular protective seat 7, and two L-shaped arc plates 9 fixedly connected to both sides inside the annular protective seat 7. A fixing plate 10 is provided on each side of the pen body 8. The pen tip at the bottom of the pen body 8 passes through the annular protective seat 7, the limiting ring pad 6, and the interior of the other side of the top of the ink chamber 2 in sequence. A connecting plate 11 is fixedly connected to the opposite side of the two L-shaped arc plates 9. The side of the connecting plate 11 away from the L-shaped arc plate 9 is fixedly connected to the inner wall of the annular protective seat 7. A miniature cylinder 12 is fixedly installed at the center position on both sides of the annular protective seat 7. A piston rod 13 is fixedly connected to the output end of one side of the miniature cylinder 12. A push rod 14 is fixedly connected to one side of the piston rod 13. One side of the push rod 14 passes through the connecting plate 11 and the L-shaped arc plate 9 in sequence and is fixedly connected to the fixing plate 10.
[0015] The ink outlet at the bottom center of the ink cartridge 4 extends through to the inside of the top side of the ink chamber 2, and a float ball 3 is provided on one side of the top of the ink chamber 2.
[0016] A support pad 5 is fixedly connected to one side of the top of the ink connector 1, corresponding to the bottom of the ink cartridge 4. The outer side of the bottom of the ink cartridge 4 is engaged with the support pad 5.
[0017] Anti-slip pads 15 are fixedly connected to the opposite sides of the two fixed clamps 10. The side of the anti-slip pads 15 away from the fixed clamps 10 is in contact with the outer surface of the pen body 8.
[0018] A protective pad 20 is fixedly connected to the bottom of the L-shaped arc plate 9, and the top of the protective pad 20 contacts the bottom position of the outer surface of the pen body 8.
[0019] Movable grooves 16 are provided at the top and bottom positions on both sides of the annular protective seat 7. Movable rods 17 are fixedly connected at the top and bottom positions on the opposite sides of the two fixed clamping plates 10. The side of the movable rod 17 away from the fixed clamping plate 10 passes through the L-shaped arc plate 9 and the annular protective seat 7 and extends into the interior of the movable groove 16, and is fixedly connected to the limiting slider 18. The limiting slider 18 is slidably connected to the movable groove 16.
[0020] A buffer spring 19 is fitted on the surface of the movable rod 17. The two sides of the buffer spring 19 are fixedly connected to the inner wall of the L-shaped arc plate 9 and the outer side of the fixed clamping plate 10, respectively.
[0021] Working principle: The ink cartridge 4 is placed on the top side of the ink connector 1 and is connected to the ink chamber 2 through the ink outlet at its bottom. When the ink in the ink cartridge 4 flows into the ink chamber 2, the float 3 will rise with the rise of the ink level. This design not only ensures a stable supply of ink, but also the position of the float 3 directly reflects the amount of ink in the ink chamber 2, making it convenient for the user to replenish the ink in time. The user inserts the tip of the pen body 8 through the opening in the center of the annular protective seat 7 until the tip enters the ink chamber 2. The design of the limiting ring pad 6 helps to prevent the pen body 8 from moving excessively in the vertical direction, thus achieving initial limiting. When the pen body 8 is placed in the designated position, the micro cylinder 12 starts to work. By extending and retracting the piston rod 13, the push rod 14 pushes the fixing clamp 10 to move along the inner wall of the L-shaped arc plate 9 towards the pen body 8. Since the fixing clamp 10 is connected to the L-shaped arc plate 9 through the connecting plate 11, they can work together to achieve a firm clamping of the pen body 8. The anti-slip pad 15 on the inner side of the fixing clamp 10 increases the friction with the outer surface of the pen body 8, preventing the pen from sliding during the ink filling process. At the same time, the protective pad 20 at the bottom of the L-shaped arc plate 9 provides additional support for the pen body 8. This design reduces potential damage caused by shaking or external forces. As the fixed clamp 10 moves, the movable rod 17 also moves and slides within the movable groove 16 via the limiting slider 18. This design not only ensures the stability and guidance of the fixed clamp 10 during movement, but also achieves a gentle clamping of the pen body 8 through the introduction of the buffer spring 19. When the fixed clamp 10 contacts the pen body 8, the buffer spring 19 absorbs part of the impact force, thereby reducing potential damage to the pen caused by excessive clamping.
[0022] In summary, this ink-filling device for fountain pen manufacturing, through the L-shaped arc plate 9 and the fixing clamp 10 within the annular protective seat 7, and in conjunction with the piston rod 13 and push rod 14 driven by the micro cylinder 12, achieves efficient and flexible limiting and fixing of the fountain pen body 8. This design not only ensures the stability of the fountain pen during the ink-filling process but also greatly improves the accuracy and uniformity of ink filling. The precise control of the micro cylinder 12 allows the fixing clamp 10 to adaptively adjust according to fountain pens of different specifications and sizes, thereby enhancing the versatility and compatibility of the device. The anti-slip pad 15 on the inner side of the pen effectively prevents the pen from sliding during the limiting process, further ensuring the stability of the pen. The protective pad 20 inside the L-shaped arc plate 9 provides additional support and protection for the bottom of the pen, avoiding damage caused by pen shaking or improper position. The combined design of the movable groove 16, movable rod 17 and limiting slider 18 not only ensures the stability and guidance of the fixed clamp 10 during the movement, but also achieves a gentle clamping of the pen through the introduction of the buffer spring 19, reducing the potential damage to the pen caused by excessive clamping.
