[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0018] like Figure 1-4As shown, an automatic filling device for ink production includes a frame 1. A storage tank 11 is located at the top of the frame 1, and a conveying pipe 12 extending outwards is located at the bottom of the storage tank 11. A fixing seat 13 is located at the end of the conveying pipe 12, and a filling nozzle 2 communicating with the conveying pipe 12 is located at the bottom of the fixing seat 13. The storage tank stores the produced ink at the top of the frame. The ink is conveyed from the storage tank along the conveying pipe to the filling nozzle, and then filled into the ink container through the filling nozzle. A sealing plate 21 is located on the inner wall of the liquid outlet at the bottom of the filling nozzle 2, and a liquid outlet hole 22 is provided on the sealing plate 21. The sealing plate is fixed to the filling nozzle. When ink is conveyed... After entering the filling nozzle, the ink is discharged from the outlet hole to fill the ink container. A rotating shaft 23, coaxially arranged with the filling nozzle 2, is located in the middle of the sealing plate 21. The shaft is rotatably connected to the sealing plate. A baffle 24, which rotates with the shaft 23 to open and close the outlet hole 22, is located at the lower end of the shaft 23, corresponding to the area below the sealing plate 21. A paddle 25, which rotates with the ink flow, is located at the upper end of the shaft 23. A torsion spring 231, connected to the sealing plate 21, is located on the side wall of the shaft 23 inside the filling nozzle. When the paddle 25 rotates, it drives the baffle 24 to rotate via the shaft 23. When ink delivery has not started, the torsion spring acts on the shaft, causing the shaft to rotate through the torsion spring. The baffle is forcefully closed to seal the outlet. As the ink flows, its fluidity drives the blades and shaft to rotate. The driving force of the ink's fluidity on the blades is greater than the force of the torsion spring. The shaft resists the torsion spring's force and drives the baffle to rotate synchronously away from the outlet, rotating below the sealing plate, thus opening the outlet and allowing the ink to flow continuously. When filling is complete, the delivery pipe stops supplying ink. At this time, some ink continues to flow inside the filling nozzle until it is discharged. After the ink stops flowing, the blades are stationary without power. The torsion spring acts synchronously on the shaft, causing the shaft to rotate... The shaft drives the baffle to reverse, instantly sealing the liquid outlet, thus completing the automatic ink filling process. At the same time, it effectively prevents ink dripping, ensures the cleanliness of the filling environment, avoids contamination of components, and avoids ink waste. In this embodiment, both the liquid outlet and the sealing plate are 180° fan-shaped structures, ensuring that the liquid outlet can discharge to the maximum extent while ensuring that the baffle can avoid and seal the liquid outlet. The upper side wall of the filling nozzle is provided with threads, and the bottom of the fixing seat is provided with an annular connecting part. The upper end of the filling nozzle is threaded to the annular connecting part. An O-ring can be set at the connection to enhance the sealing performance, so as to facilitate the assembly and maintenance of the filling nozzle.
[0019] like Figure 2-4As shown, a limiting block 211 is provided at the junction of the bottom of the sealing plate 21 and the liquid outlet 22, corresponding to the rotation path of the baffle 24. During ink delivery, the baffle is driven by the paddle and the rotating shaft to rotate toward the liquid outlet. When the baffle completely closes the liquid outlet, the side wall of the baffle is blocked by the limiting block to prevent the baffle from moving excessively and causing it to leak out of the liquid outlet again, thus ensuring the effective sealing of the liquid outlet by the baffle. At the same time, after the baffle is rotated by the torsion spring, the limiting block blocks the baffle again, ensuring that the baffle is positioned below the sealing plate, preventing ink from flowing out of the liquid outlet. The edge of the liquid outlet 22 has an outward protrusion 221 that protrudes from the inner wall of the filling nozzle 2. The outward protrusion 221 can abut against the edge of the baffle 24. The setting of the outward protrusion allows the edge of the baffle to abut against the outward protrusion when the baffle closes the liquid outlet, thereby enhancing the sealing effect of the liquid outlet. The side of the sealing plate 21 facing the inner side of the filling nozzle 2 has a slope structure that gradually slopes downward from the edge toward the liquid outlet 22. The setting of the slope structure can reduce the accumulation of ink above the sealing plate and help the ink to be discharged from the liquid outlet better.
[0020] like Figure 3 As shown, a rotary bearing 232, connected to the sealing plate 21, is fixed on the side wall of the rotating shaft 23 above the baffle 24, corresponding to the side wall of the rotating shaft 23. The upper end of the rotating shaft 23 is fixedly connected to the blade 25, and the lower end of the rotating shaft 23 is fixedly connected to the baffle 24. The middle part of the rotating shaft rotates smoothly through the rotary bearing connected to the sealing plate. When the blade is driven to rotate by the flowing ink, the blade can drive the rotating shaft to rotate synchronously, and the rotating shaft can thus drive the baffle to rotate synchronously. A positioning housing 26, connected to the sealing plate 21, is provided on the side wall of the rotating shaft 23 above the rotary bearing 232. The body 26 has a torsion spring 231 inside, which is fixedly connected at both ends to the rotating shaft 23 and the inner wall of the positioning housing 26 respectively. The top of the positioning housing 26 has an annular protrusion 261 that slides with the side wall of the rotating shaft 23. The torsion spring is located inside the positioning housing, which can reduce the contact between the torsion spring and the ink, reduce the damage to the torsion spring, and extend the service life of the torsion spring. The positioning housing is connected and fixed to the sealing plate and forms a positioning support for the rotating shaft, which enhances the stability of the rotating shaft and facilitates assembly. The setting of the annular protrusion can enhance the positioning effect of the rotating shaft and ensure that the rotating shaft is more stable and reliable.
[0021] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
