Description

Technical Field

[0001] This utility model relates to the field of label printing technology, specifically to an ink dispensing device for label printing. Background Technology

[0002] In the label printing industry, ink mixing is a crucial step. Label printing ink mixing involves precisely mixing different colors and types of base inks in specific proportions to meet specific printing needs. This process must not only ensure that the mixed ink color meets design requirements but also guarantee that the ink possesses suitable fluidity, drying speed, and adhesion properties to achieve a clear and uniform printing effect, allowing the label to present the expected visual appeal and durability.

[0003] During long-term use, ink residue can accumulate in various parts of the ink mixing device. If not cleaned promptly and effectively, this residue will dry and clump, affecting the accuracy of subsequent ink mixing and causing color deviations. Furthermore, it can breed bacteria and mold, contaminating newly mixed ink and ultimately impacting label printing quality and hygiene standards. In addition, traditional manual cleaning methods are typically labor-intensive, resource-intensive, and time-consuming, increasing production costs and reducing efficiency. To facilitate convenient and efficient cleaning of the ink mixing device after mixing and prevent residual ink from negatively impacting subsequent mixing operations and printing quality, we propose an ink mixing device for label printing.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: an ink dispensing device for label printing, including a mounting frame 1, an ink dispensing tank 2 fixedly mounted on the mounting frame 1, a feeding port 3 fixedly connected to the left side of the ink dispensing tank 2, a discharge port 4 fixedly connected to the bottom of the ink dispensing tank 2, a solenoid valve provided on the discharge port 4, a transparent observation window 7 provided on the ink dispensing tank 2, a control box 6 fixedly mounted on the ink dispensing tank 2, a stirring component for stirring the ink liquid installed on the ink dispensing tank 2, a cleaning component for cleaning the inside of the ink dispensing tank 2 installed on the ink dispensing tank 2, and a drive component for driving the stirring component and the cleaning component to operate on the ink dispensing tank 2;

[0029] The cleaning assembly includes a liquid storage tank 13, which is rotatably connected to the inner wall of the ink tank 2. Several sets of second rotary joints 29 are fixedly connected to the bottom of the liquid storage tank 13. Rotary tubes 17 are rotatably connected to the bottom of the second rotary joints 29. Several sets of cleaning nozzles 18 are fixedly connected to the outside of the rotary tubes 17. A scraping mechanism is installed on the ink tank 2 to prevent ink from adhering to the inner wall of the ink tank 2.

[0030] The scraping mechanism includes several sets of mounting covers 26, which are fixedly connected to the bottom of the liquid storage tank 13. A sliding plate 34 is slidably connected to the inner wall of the mounting cover 26. Several sets of connecting rods 33 are fixedly connected to the side of the sliding plate 34 near the ink tank 2. The connecting rods 33 slide through the mounting cover 26. A scraper 25 is fixedly connected to the end of the connecting rod 33 away from the sliding plate 34. The side of the scraper 25 near the ink tank 2 abuts against the inner wall of the ink tank 2.

[0031] During use, inks of various colors are added to the ink mixing tank 2 through the feeding port 3 according to the ink mixing requirements. The stirring component is driven by the drive component to stir the inks of various colors to mix them quickly and improve the ink mixing efficiency. After the ink mixing is completed, the solenoid valve is opened and the ink flows out from the discharge port 4. Then, the cleaning liquid is injected into the storage tank 13 by the external liquid pump. The cleaning liquid is sprayed out from the cleaning nozzle 18 through the rotating tube 17. Under the action of the drive component, the storage tank 13 rotates, which drives the rotating tube 17 to revolve. The rotating tube 17 also rotates on its own axis, which drives the cleaning nozzle 18 to rotate, cleaning the inside of the ink mixing tank 2 from all directions. At the same time, the rotation of the storage tank 13 drives the mounting cover 26 to rotate, which in turn causes the scraper 25 to rotate and scrape off the ink adhering to the inner wall of the ink mixing tank 2, ensuring the cleaning effect. This achieves convenient and efficient cleaning of the ink mixing device after ink mixing, preventing residual ink from adversely affecting subsequent ink mixing operations and printing quality.

[0032] Several sets of lower nozzles 19 and upper nozzles 20 are fixedly connected to the outside of the rotating tube 17. The lower nozzles 19 are set at an angle downwards, and the upper nozzles 20 are set at an angle upwards. The upper nozzles 20 and lower nozzles 19 can clean the top and bottom of the inner wall of the ink tank 2 to ensure that there is no residual ink in the ink tank 2.

[0033] The mixing assembly includes several sets of mounting cylinders 21, which are rotatably sleeved on the outside of the rotating tube 17. Several sets of mixing frames 15 are fixedly installed between two sets of mounting cylinders 21, and mixing rods are provided on the mixing frames 15.

[0034] Under the action of the drive component, multiple sets of stirring racks 15 revolve around the reservoir 13 as it rotates, while the mounting cylinder 21 rotates, causing the stirring racks 15 to rotate on their own axis, thus stirring the ink in the ink tank 2.

[0035] The drive assembly includes a motor 8, which is fixedly mounted on the top of the ink tank 2. The output end of the motor 8 is fixedly connected to a drive gear 24. The top of the liquid storage tank 13 is fixedly connected to a connecting pipe 22. A driven gear 23 is fixedly sleeved on the outside of the connecting pipe 22. The driven gear 23 meshes with the drive gear 24. A first rotating mechanism that drives the rotating tube 17 to rotate is installed on the ink tank 2.

[0036] When the motor 8 is started, it drives the drive gear 24 to rotate, which in turn causes the connecting pipe 22 to rotate through the driven gear 23, thus rotating the liquid storage tank 13.

[0037] The first rotating mechanism includes a mounting plate 10, which is fixedly connected to the inner wall of the ink tank 2. The connecting pipe 22 rotates through the mounting plate 10. A fixed cylinder 16 is fixedly connected to the bottom of the mounting plate 10. The fixed cylinder 16 is rotatably sleeved on the outside of the connecting pipe 22. A fixed gear 12 is fixedly sleeved on the outside of the fixed cylinder 16. A connecting block 28 is fixedly connected to the inner wall of the rotating pipe 17. Several sets of through holes are opened on the connecting block 28. A rotating rod 27 is fixedly connected to the top of the connecting block 28. The rotating rod 27 rotates through the liquid storage tank 13. A rotating gear 11 is fixedly connected to the top of the rotating rod 27. The rotating gear 11 meshes with the fixed gear 12. A second rotating mechanism that drives the mounting cylinder 21 to rotate is installed on the liquid storage tank 13.

[0038] When the liquid storage tank 13 rotates, it causes the rotating tube 17 to revolve, which in turn causes the rotating rod 27 to revolve, driving the rotating gear 11 to rotate around the fixed gear 12. The meshing of the rotating gear 11 and the fixed gear 12 causes the rotating gear 11 to rotate on its own axis, which in turn drives the rotating tube 17 to rotate on its own axis through the rotating rod 27 and the connecting block 28.

[0039] The second rotating mechanism includes several sets of protective covers 14. The protective covers 14 are fixedly connected to the bottom of the liquid storage tank 13. The upper mounting cylinder 21 rotates through the protective cover 14. A transmission bevel gear 31 is rotatably installed on the inner wall of the protective cover 14. A driving bevel gear 30 is fixedly sleeved on the outside of the rotating tube 17. A driven bevel gear 32 is fixedly sleeved on the outside of the upper mounting cylinder 21. The transmission bevel gear 31 meshes with the driving bevel gear 30 and the driven bevel gear 32.

[0040] The rotation of the rotating tube 17 drives the active bevel gear 30 to rotate, which in turn drives the driven bevel gear 32 to rotate via the transmission bevel gear 31. This causes the upper mounting cylinder 21 to rotate, which in turn drives the stirring frame 15 to rotate.

[0041] The top of the connecting pipe 22 is fixedly connected to a first rotary joint 9, and the top of the first rotary joint 9 is rotatably connected to an injection pipe 5, which is fixedly installed on the side wall of the ink tank 2. The cleaning solution is injected into the storage tank 13 through the injection pipe 5.

[0042] Several sets of springs 38 are fixedly connected to the side of the sliding plate 34 away from the connecting rod 33. The end of the spring 38 away from the sliding plate 34 is fixedly connected to the inner wall of the mounting cover 26. This ensures that the scraper 25 always fits against the inner wall of the ink tank 2, while preventing excessive pressure from the scraper 25 from damaging the ink tank 2.

[0043] A connecting cylinder 36 is slidably connected to the inner wall of the feeding port 3, and a filter frame 35 is fixedly connected to the inner wall of the connecting cylinder 36. A limit ring 37 is fixedly connected to the end of the connecting cylinder 36 away from the feeding port 3. The raw ink can be filtered through the filter frame 35 to prevent clumping and ensure product quality. The connecting cylinder 36 and the filter frame 35 can be easily removed for cleaning through the limit ring 37.

[0044] Working principle: In use, according to the ink mixing requirements, add the various colors of ink into the ink mixing tank 2 through the feeding port 3. Start the motor 8 to drive the drive gear 24 to rotate, which in turn causes the connecting pipe 22 to rotate through the driven gear 23. This causes the storage tank 13 to rotate, which in turn causes the rotating pipe 17 to revolve. This causes the rotating rod 27 to revolve, which in turn causes the rotating gear 11 to rotate around the fixed gear 12. The meshing of the rotating gear 11 and the fixed gear 12 causes the rotating gear 11 to rotate on its own axis. This rotation causes the rotating pipe 17 to rotate through the rotating rod 27 and the connecting block 28. The rotation of the rotating pipe 17 causes the driving bevel gear 30 to rotate, which in turn causes the driven bevel gear 32 to rotate through the transmission bevel gear 31. This causes the upper mounting cylinder 21 to rotate, which in turn causes the stirring frame 15 to rotate, thus mixing the various colors of ink. Stirring is performed to quickly mix the ink and improve ink mixing efficiency. After ink mixing is completed, the solenoid valve is opened, and the ink flows out from the outlet 4. Then, the cleaning solution is injected into the storage tank 13 by an external liquid pump. The cleaning solution is sprayed out from the cleaning nozzle 18 through the rotating tube 17. Under the action of the drive component, the storage tank 13 rotates, which drives the rotating tube 17 to revolve. The rotating tube 17 also rotates on its own axis, which drives the cleaning nozzle 18 to rotate, cleaning the inside of the ink mixing tank 2 from all directions. At the same time, the rotation of the storage tank 13 drives the mounting cover 26 to rotate, which in turn causes the scraper 25 to rotate, scraping off the ink adhering to the inner wall of the ink mixing tank 2, ensuring the cleaning effect. This achieves convenient and efficient cleaning of the ink mixing device after ink mixing, preventing residual ink from adversely affecting subsequent ink mixing operations and printing quality.
