[0001] The utility model relates to the technical field of printer ink production, in particular to a filling machine for printer ink production. Background Technique

[0002] An inkjet printer is a common printing device that uses inkjet technology to eject ink onto paper to form images or text. During the production process of printer ink, it is filled into a bottle body through a filling machine to achieve the storage of printer ink. Some filling machines include a base, and several conveyor belts are installed on the top of the base. A filling mechanism is provided on the top of each conveyor belt. The filling mechanism includes a connecting frame, a baffle, an ink injection cylinder, an electric valve, a liquid outlet pipe, a slider, and an electric telescopic rod. When filling printer ink, the telescopic end of the electric telescopic rod drives the ink injection cylinder to move vertically, thereby adjusting the filling height of the printer ink, which is applicable to bottle bodies of different heights and improves its applicability. However, after the ink injection cylinder fills the printer ink into the bottle body, there is usually some printer ink remaining at the ink injection nozzle part of the ink injection cylinder. As the equipment operates, this remaining ink is likely to fall onto the conveyor belt, and subsequent cleaning is inconvenient, which needs to be improved. Content of the Utility Model

[0020] Please refer to Figure 1-2 , this embodiment provides a technical solution: a filling machine for printer ink production, including a filling platform 1 and an anti-dripping mechanism 7;

[0021] Filling platform 1: A filling nozzle 5 is installed above it, and it also includes a single-chip microcomputer 2.

The input end of the solenoid valve 6 is electrically connected to the output end of the single-chip microcomputer 2. An electro-hydraulic push rod 8 is provided on the upper side of the mounting rack 3. The input end of the electro-hydraulic push rod 8 is electrically connected to the output end of the single-chip microcomputer 2. The telescopic end of the electro-hydraulic push rod 8 is fixedly connected to the upper side of the lifting seat 4. An ink tank 9 is provided on the upper side of the filling platform 1. A hard pipe 11 is provided at the liquid outlet of the ink tank 9 through a liquid supply pump 10. The input end of the liquid supply pump 10 is electrically connected to the output end of the single-chip microcomputer 2. The front end of the hard pipe 11 is connected to the top of the filling nozzle 5 through a flexible pipe 12. A belt conveyor 13 is provided on the upper side of the filling platform 1. The input end of the belt conveyor 13 is electrically connected to the output end of the single-chip microcomputer 2. When filling printer ink, the single-chip microcomputer 2 starts the belt conveyor 13 to convey the filling bottles of printer ink through the belt. The single-chip microcomputer 2 starts the electro-hydraulic push rod 8 to drive the lifting seat 4 to slide vertically along the chute through its telescopic end, so as to adjust the filling height of the printer ink of the device;

[0022] Anti-drip mechanism 7: It includes an annular groove 71, a conical seat 72, an arched seat 75, a second telescopic column 76, a second spring 77, a plugging seat 78 and a space adjustment component 79. The annular groove 71 is opened on the inner wall of the filling nozzle 5. A conical seat 72 is slidably connected inside the annular groove 71. An arched seat 75 is provided on the upper side of the conical seat 72. A plugging seat 78 is provided on the top wall of the arched seat 75 through the second telescopic column 76 and the second spring 77. The second spring 77 is movably sleeved on the outer end of the second telescopic column 76. A space adjustment component 79 is provided between the arched seat 75 and the filling nozzle 5. The anti-drip mechanism 7 further includes a first telescopic column 73 and a first spring 74. The first telescopic column 73 and the first spring 74 are uniformly arranged between the annular groove 71 and the conical seat 72. The first spring 74 is movably sleeved on the outer end of the adjacent first telescopic column 73. The space adjustment component 79 includes a hollow shell 791, a circular seat 792 and a synchronous rod 793. The hollow shell 791 is arranged inside the filling nozzle 5. A circular seat 792 is slidably connected inside the hollow shell 791. The lower side of the circular seat 792 is fixedly connected to the upper side of the arched seat 75 through the synchronous rod 793. When filling the printer ink, first, the single-chip microcomputer 2 opens the solenoid valve 6. Subsequently, the single-chip microcomputer 2 starts the liquid supply pump 10 to convey the printer ink in the ink tank 9 to the filling nozzle 5 through the hard pipe 11 and the flexible pipe 12. Since the compression elastic force of the first spring 74 is less than the tensile elastic force of the second spring 77, after the printer ink enters the filling nozzle 5, a downward pressure is applied to the conical seat 72 through the conveying pressure. The conical seat 72 drives the plugging seat 78 to move vertically downward. The telescopic end of the first telescopic column 73 and the first spring 74 gradually contract. The conical seat 72 makes the synchronous rod 793 drive the circular seat 793 to slide vertically downward along the hollow shell 791 through the arched seat 75. At this time, the hollow space formed between the upper side of the circular seat 793 in the hollow shell 791 and the top wall of the hollow shell 791 gradually increases, and the available space for storing the printer ink in the hollow shell 791 gradually decreases. When the conical seat 72 slides vertically downward along the annular groove 71 by a certain distance, at this time, the compression elastic force of the first spring 74 is equal to the sum of the tensile elastic force of the second spring 77 and the conveying pressure applied by the printer ink to the conical seat 72 and the plugging seat 78. Next, the telescopic end of the second telescopic column 76 and the second spring 77 gradually stretch, and the plugging seat 78 moves away from the conical seat 72, so that the plugging opening between the two is opened. Subsequently, the printer ink flows out through the lower end of the filling nozzle 5 to fill the filling bottle. After the filling bottle is filled with the printer ink, the single-chip microcomputer 2 closes the solenoid valve 6. At this time, the printer ink conveying pressure disappears. Through the compression elastic force of the first spring 74 and the tensile elastic force of the second spring 77, the plugging seat 78 contacts and closes with the conical seat 72. At the same time, the plugging seat 78 and the conical seat 72 move vertically upward to reset together. As the conical seat 72 moves upward, the conical seat 72 drives the circular seat 792 to move vertically upward along the hollow shell 791 through the arched seat 75 and the synchronous rod 793, so that the available space for storing the printer ink in the hollow shell 791 gradually decreases, and further, the storage space of the printer ink in the filling nozzle 5 is larger than the initial state.The air pressure inside the filling nozzle 5 is less than the external air pressure, causing the printer ink below the filling nozzle 5 to flow back into the filling nozzle 5, preventing the printer ink at the nozzle part below the filling nozzle 5 from dropping onto the belt conveyor 13. This device utilizes the air pressure difference through elastic elements to make the printer ink at the nozzle of the filling nozzle 5 flow back after ink filling, avoiding its dropping onto the conveyor belt and being convenient to use.

[0023] The working principle of a filling machine for printer ink production provided by the present utility model is as follows: When filling printer ink, the single-chip microcomputer 2 starts the belt conveyor 13 to convey the filling bottles of printer ink through the belt. The single-chip microcomputer 2 starts the electro-hydraulic push rod 8, and its telescopic end drives the lifting seat 4 to slide vertically along the chute, thereby adjusting the filling height of the printer ink of the device. When filling printer ink, first, the single-chip microcomputer 2 opens the solenoid valve 6, and then the single-chip microcomputer 2 starts the liquid supply pump 10 to convey the printer ink in the ink tank 9 into the filling nozzle 5 through the hard pipe 11 and the flexible pipe 12. Since the compression elastic force of the first spring 74 is less than the tensile elastic force of the second spring 77, after the printer ink enters the filling nozzle 5, it exerts a downward pressure on the conical seat 72 through the conveying pressure. The conical seat 72 drives the plugging seat 78 to move vertically downward. The telescopic end of the first telescopic column 73 and the first spring 74 gradually contract. The conical seat 72 makes the synchronous rod 793 drive the round seat 793 to slide vertically downward along the hollow shell 791 through the arched seat 75. At this time, the hollow space formed between the upper side of the round seat 793 in the hollow shell 791 and the top wall of the hollow shell 791 gradually increases, and the available space for storing printer ink in the hollow shell 791 gradually decreases. When the conical seat 72 slides vertically downward along the annular groove 71 for a certain distance, at this time, the compression elastic force of the first spring 74 is equal to the sum of the tensile elastic force of the second spring 77 and the conveying pressure exerted by the printer ink on the conical seat 72 and the plugging seat 78. Next, the telescopic end of the second telescopic column 76 and the second spring 77 gradually stretch, and the plugging seat 78 moves away from the conical seat 72, thereby opening the plugging port between the two. Then, the printer ink flows out from the lower end of the filling nozzle 5 to fill the filling bottle. After the filling bottle is filled with printer ink, the single-chip microcomputer 2 closes the solenoid valve 6. At this time, the printer ink conveying pressure disappears. Through the compression elastic force of the first spring 74 and the tensile elastic force of the second spring 77, the plugging seat 78 contacts and closes with the conical seat 72. At the same time, the plugging seat 78 and the conical seat 72 move vertically upward to reset together. As the conical seat 72 moves upward, the conical seat 72 drives the round seat 792 to move vertically upward along the hollow shell 791 through the arched seat 75 and the synchronous rod 793, so that the available space for storing printer ink in the hollow shell 791 gradually decreases, and further makes the storage space of the printer ink in the filling nozzle 5 larger than the initial state. The air pressure inside the filling nozzle 5 is less than the external air pressure, causing the printer ink below the filling nozzle 5 to flow back into the filling nozzle 5, preventing the printer ink at the nozzle part below the filling nozzle 5 from dropping onto the belt conveyor 13 and being convenient to use.
