Description

Technical Field

[0001] This invention relates to the field of ink filling technology, specifically to an automatic ink filling and labeling integrated machine. Background Technology

[0002] Ink is a liquid or paste-like substance widely used in printing, writing, and marking. It is usually composed of pigments, binders, solvents, and additives. With the development of industries such as printing and packaging, the demand for fluid materials such as ink is increasing, and higher requirements are also being placed on the filling accuracy and efficiency of these materials.

[0003] Currently, in the capacitor and resistor industry, ink in the original printing process is added manually. The decision to add ink is made manually based on the printing quantity. Factories typically have hundreds of printing machines, requiring a large amount of manpower, which reduces filling efficiency. Furthermore, relying on manual management of the amount added introduces subjective bias, making it difficult to guarantee consistency and accuracy in filling quantities. This fails to meet the demand for precise filling, leading to inconsistent amounts when used in batches on printing equipment, resulting in poor production continuity and the inability to establish constant standard quantities for the process, impacting subsequent cost accounting. Additionally, manual ink addition may result in contact with the ink, inevitably causing contamination or other quality issues, reducing filling quality. Moreover, manual labeling is inefficient and time-consuming, lacking traceability of production quality.

[0004] Therefore, an automatic ink filling and labeling integrated machine was proposed. Summary of the Invention

[0005] This invention provides an automatic ink filling and labeling integrated machine. Through the sliding of a piston block within a piston cylinder, and in conjunction with a switching valve, ink is drawn from the ink hopper and then transported by the piston cylinder to the ink filling tube. Furthermore, a lifting cylinder and a gravity sensor weigh the ink container to achieve quantitative filling. The weighing data can also be used to determine if the quantitative solenoid valve is malfunctioning. This solves the problem mentioned in the background art where traditional filling relies on manual management of the amount added, leading to subjective biases and difficulty in ensuring consistency and accuracy of the filling volume, thus failing to meet the requirements for precise filling.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Reference Figures 1-8An automatic ink filling and labeling integrated machine includes a worktable 1 and a piston cylinder 2. The piston cylinder 2 is fixedly connected to the top of the worktable 1. One end of the piston cylinder 2 is fixed and connected to a switching valve 21. The top of the switching valve 21 is fixed and connected to an ink hopper 22. The top of the ink hopper 22 is fixedly connected to a sealing cap 221. The top of the sealing cap 221 is fixed and connected to a negative pressure suction tube 222. The other end of the negative pressure suction tube 222 is connected to an existing negative pressure suction device through a conduit. The other side of the switching valve 21 is fixed and connected to an ink injection tube 23. The switching valve 21 adopts existing mature three-way valve technology. The connection between the ink hopper 22 and the piston cylinder 2, or the connection between the piston cylinder 2 and the ink injection tube 23, is achieved by the rotation of the valve core driven by a motor. The workbench 1 is used to draw ink from the ink hopper 22 into the piston cylinder 2 and then push it into the ink filling tube 23. A liquid guide is provided on the top of the workbench 1 to transport the ink from the ink hopper 22 to the ink filling tube 23. A translation slide 3 is used, on which an oil tank tray 31 is slidably mounted. The translation slide 3 uses existing mature technology to drive the oil tank tray 31 to slide along the translation slide 3, achieving continuous filling operations. Multiple sets of ink tanks 32 are inserted into the oil tank tray 31. A weighing part is located directly below the ink filling tube 23 to weigh the amount of ink injected into the ink tank 32. A labeling mechanism is installed at the bottom of the workbench 1 and is used to affix labels to the side walls of the ink tanks 32.

[0023] Reference Figures 1-3 The liquid guiding part includes a positioning seat 4, a displacement screw 41 rotatably connected to the middle of the inner wall of the positioning seat 4, and limit guide rods 42 fixedly connected to both sides of the inner wall of the positioning seat 4. A displacement seat 43 is sleeved on the displacement screw 41 and the limit guide rod 42. The displacement seat 43 is threadedly connected to the displacement screw 41, and slidably connected to the limit guide rod 42. A push-pull rod 44 is fixedly connected to the top of the displacement seat 43. A piston block 24 is slidably connected inside the piston cylinder 2. The end of the push-pull rod 44 is fixedly connected to the side wall of the piston block 24. A liquid guiding motor 45 is fixedly connected to the side wall of the positioning seat 4. The output shaft of the liquid guiding motor 45 is fixedly connected to the end of the displacement screw 41. An ink injection cylinder 231 is fixedly connected to the top of the ink injection tube 23. An ink push column 232 is slidably connected inside the ink injection tube 23. The telescopic end of the ink injection cylinder 231 is fixedly connected to the top of the ink push column 232. A quantitative solenoid valve is provided inside the output end of the ink injection tube 23.

[0024] With the above structure, firstly, the switching valve 21 is rotated to connect the ink hopper 22 with the piston cylinder 2. Then, the liquid guiding motor 45 is turned on, causing it to drive the displacement screw 41 to rotate. This causes the displacement seat 43 to slide along the displacement screw 41 towards the side closer to the liquid guiding motor 45, thereby pulling the piston block 24 to slide towards the side closer to the liquid guiding motor 45 as well. At this time, a negative pressure suction force is generated inside the piston cylinder 2, which, combined with the gravity of the ink in the ink hopper 22, gradually fills the entire piston cylinder 2 with ink. Then, the switching valve 21 is rotated to connect the piston cylinder 2 with the ink injection tube 23. At this time, the liquid guiding motor 45 is turned on again, causing the displacement seat 43 to push the piston block 24 towards the side closer to the ink injection tube 23, thereby pushing the ink in the piston cylinder 2 into the ink injection tube 23. After the ink tank 32 moves to the bottom of the ink injection tube 23, the quantitative solenoid valve can be opened to perform the filling operation. This achieves automated and precise quantitative filling, ensuring filling quality while reducing manpower consumption and improving filling efficiency. This generates 32 standard weight ink cans for equipment use, enabling precise quantitative management and facilitating subsequent cost accounting for customers.

[0025] Among them, a shielding ring 233 is fixedly connected to the outer wall of the output end of the ink injection tube 23. The inner cavity of the shielding ring 233 is higher than the bottom of the output of the ink injection tube 23. An air injection hole 234 is opened on the outer wall of the shielding ring 233. The inner end of the air injection hole 234 is connected to the inner cavity of the shielding ring 233, and the outer end of the air injection hole 234 is connected to the existing air filling equipment through a conduit.

[0026] With the above-described structure, the shielding ring 233 can effectively prevent ink from splashing out of the ink outlet of the ink tube 23 under pressure, thus improving the cleanliness of the filling area. Furthermore, the outer end of the air injection hole 234 is connected to the existing air filling equipment through a conduit, so that after each filling, the airflow blows onto the inner wall of the shielding ring 233, causing the ink adhering to the inner wall of the shielding ring 233 to be blown off into the ink tank 32, avoiding the loss of the set amount of ink and ensuring the filling quality of the ink.

[0027] Reference Figures 4-6 The system also includes a positioning frame 5 and a weighing unit including a lifting cylinder 51. The lifting cylinder 51 is fixed to the side wall of the positioning frame 5. A double-headed cylinder 52 is fixedly connected to the top of the telescopic end of the lifting cylinder 51. Clamping claws 53 are fixedly connected to both telescopic ends of the double-headed cylinder 52. A gravity sensor 54 is fixedly connected to the outer wall of the clamping claw 53. The sensing area of ​​the gravity sensor 54 is located at the top of the double-headed cylinder 52, and the bottom end of the ink tank 32 is located directly above the sensing area of ​​the gravity sensor 54. A protrusion 321 is provided on the top of the ink tank 32, and the outer diameter of the protrusion 321 is larger than the inner diameter of the insertion groove of the oil tank tray 31.

[0028] With the above structure, the oil tank tray 31 first slides along the translation slide 3, moving the ink tank 32 directly below the ink filling tube 23. Then, the ink filling cylinder 231 pulls the ink pusher 232 upward, allowing the ink in the ink filling tube 23 to enter the inner cavity of the input end of the ink filling tube 23. Then, the lifting cylinder 51 pushes the double-headed cylinder 52 upward, causing the bottom of the ink tank 32 to contact the sensing area of ​​the gravity sensor 54 at the top of the double-headed cylinder 52, and causing the top protrusion 321 of the ink tank 32 to detach from the oil tank tray 31. This ensures that the entire weight of the ink filling tube 23 acts on the sensing area of ​​the gravity sensor 54, thereby weighing the ink tank 32. Then, the quantitative solenoid valve in the ink filling tube 23 is opened, allowing a quantitative amount of ink to be injected into the ink tank 32. In conjunction with the weighing action, quantitative filling of each set of ink tanks 32 is achieved, ensuring filling quality. Moreover, the weighing data can be used to determine whether there is a malfunction in the quantitative solenoid valve, so as to carry out timely maintenance.

[0029] Reference Figure 1 , Figure 7 and Figure 8 The system also includes a frame 7 installed at the bottom of the workbench 1. The labeling mechanism includes a control box 6, which is fixedly connected to the top of the frame 7. A feeding roller 61 and a receiving roller 62 are rotatably connected to the side wall of the control box 6. Multiple sets of guide rollers 63 are rotatably connected to the side wall of the control box 6. An online printer 64 is fixedly connected to the side wall of the control box 6. The online printer 64 uses existing mature technology; a specific model such as ZT610 can be used. Label tape is wound around the feeding roller 61, and the label tape passes through each set of guide rollers 63 and the online printer 64 before being fixed to the receiving roller 62. A label dispensing platform 64 is fixedly connected to the side wall of the online printer 64. 1. The label dispensing end of the online printer 64 is located next to the label dispensing platform 641, and the top of the label dispensing platform 641 has a serrated design. The serrated design can greatly reduce the contact area between the adhesive surface of the label bottom and the label dispensing platform 641, so as to better remove the label; the bottom of the frame 7 is fixedly connected to the labeling cylinder 65, the telescopic end of the labeling cylinder 65 is fixedly connected to the mounting frame 651, the top of the mounting frame 651 is fixedly connected to the rotary cylinder 66, the rotating end of the rotary cylinder 66 is fixedly connected to the lifting cylinder 67, the top of the telescopic end of the lifting cylinder 67 is fixedly connected to the label picking frame 68, and the bottom of the label picking frame 68 is fixedly connected to the negative pressure suction cup 69.

[0030] With the above-described structure, when each set of ink tanks 32 moves to a position flush with the negative pressure suction cup 69, the online printer 64 removes a set of labels, which fall onto the top of the label dispensing platform 641. At this time, through the coordinated operation of the labeling cylinder 65, the rotating cylinder 66, and the lifting cylinder 67, the negative pressure suction cup 69 moves to directly above the label. Utilizing the negative pressure generated within the suction cup 69, the label is adsorbed to its bottom. Subsequently, through the coordinated operation of the labeling cylinder 65, the rotating cylinder 66, and the lifting cylinder 67, the suction cup 69 moves to the side wall of the ink tank 32, finally affixing the label to the side wall of the ink tank 32. This allows for simultaneous labeling during the filling process, simplifying the processing steps and effectively improving production efficiency. Furthermore, the automatically generated labels can mark the filling time of each set of ink tanks 32 for traceability management and better quality control.

[0031] In addition, high-value inks need to be reheated before use, and the usage time also needs to be precisely controlled. Using the above-mentioned precise filling method, through the automatically generated label time management, we can also better manage quality and improve ink filling quality.

[0032] Reference Figures 1-8 In this invention, when in use, ink is first loaded into ink hopper 22, then the sealing cap 221 is closed, and the negative pressure suction tube 222 is connected to the negative pressure suction device through the conduit. Then the negative pressure suction device is turned on to evacuate the ink hopper 22. When the ink hopper 22 is vacuumed, the air bubbles inside the ink will quickly rise and be discharged, thus de-foaming the ink and ensuring the filling quality of the ink.

[0033] Next, the oil tank tray 31 slides along the translation slide 3, moving the ink tank 32 to directly below the ink filling tube 23. Then, the switching valve 21 is rotated to connect the ink hopper 22 with the piston cylinder 2. The liquid guiding motor 45 is then turned on, causing it to rotate the displacement screw 41. This causes the displacement seat 43 to slide along the displacement screw 41 towards the side closer to the liquid guiding motor 45, pulling the piston block 24 towards the side closer to the liquid guiding motor 45. At this time, a negative pressure suction force is generated inside the piston cylinder 2, which, combined with the gravity of the ink in the ink hopper 22, gradually fills the entire piston cylinder 2 with ink. The switching valve 21 is then rotated again to connect the piston cylinder 2 with the ink filling tube 23. The liquid guiding motor 45 is then turned on again, causing the displacement seat 43 to push the piston block 24 towards the side closer to the ink filling tube 23. One side slides, pushing the ink in the piston cylinder 2 into the ink filling tube 23. At the same time, the ink filling cylinder 231 pulls the ink pushing column 232 upward, so that the ink in the ink filling tube 23 enters the inner cavity of the input end of the ink filling tube 23. Then, the lifting cylinder 51 pushes the double-headed cylinder 52 upward, so that the bottom end of the ink tank 32 touches the sensing area of ​​the gravity sensor 54 on the top of the double-headed cylinder 52, thereby weighing the ink tank 32. Then, the quantitative solenoid valve in the ink filling tube 23 is opened, so that a quantitative amount of ink is injected into the ink tank 32. In conjunction with the weighing action, quantitative filling of each set of ink tanks 32 is achieved, ensuring the filling quality. Moreover, the weighing data can also be used to determine whether there is a malfunction in the quantitative solenoid valve, so as to carry out timely maintenance.

[0034] In addition, when each set of ink tanks 32 moves to a position flush with the negative pressure suction cup 69, the online printer 64 removes a set of labels, which fall to the top of the label dispensing platform 641. At this time, through the coordinated operation of the labeling cylinder 65, the rotary cylinder 66, and the lifting cylinder 67, the negative pressure suction cup 69 moves to directly above the label. Using the negative pressure generated inside the suction cup 69, the label is adsorbed to its bottom. Then, through the coordinated operation of the labeling cylinder 65, the rotary cylinder 66, and the lifting cylinder 67, the negative pressure suction cup 69 moves to the side wall of the ink tank 32, and finally affixes the label to the side wall of the ink tank 32. In this way, the labeling process is realized simultaneously during the filling process, simplifying the processing steps and effectively improving production efficiency.
