Description
Technical Field
[0001] This utility model belongs to the field of ink recycling technology, specifically an ink recycling device for inkjet printers. Background Technology
[0002] Inkjet printers are used to mark product packaging. In industries such as cement production, inkjet printers often use ink to mark cement bags. The ink tank is the ink storage and supply device used by the inkjet printer to store ink. Ink is usually tested before use, and the ink ejected during the test is recycled through an ink recovery unit.
[0003] Currently, with existing technologies, inks from different manufacturers and printheads from different manufacturers require repeated testing when the ink is used for the first time. The tests include the ink's driving waveform, the amount of ink dispensed per stroke, the continuity, smoothness, and sustainability of ink flow. In particular, the smoothness test requires continuous ink spraying for more than half an hour for each parameter to determine its smoothness. Therefore, changing any parameter requires more than half an hour of ink spraying, resulting in a large amount of ink being wasted during each test. This increases the cost of research and development and also increases the amount of hazardous waste.
[0004] In the existing technology, a large amount of ink is ejected from the inkjet printer printhead during the ink testing process. If the ink is not recycled, it will not only lead to a large waste of ink, but also cause the ink to contain a large amount of volatile gases with a strong odor, thus polluting the environment.
[0005] Therefore, an ink recovery device for inkjet printers is proposed to address the above problems. Utility Model Content

[0015] The beneficial effects of this utility model are: This invention provides an ink recovery device for inkjet printers. By configuring a recovery tube and a recovery hopper, the recovery tube is rotated to the bottom of the inkjet printer nozzle, then moved upwards to engage with the nozzle.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Specific implementation examples are given below.
[0020] Please see Figures 1-5 This utility model provides an ink recycling device for inkjet printers, including a base 1. A vertical rod 2 is fixedly connected to the top of the base 1, and a horizontal rod 3 is installed on the vertical rod 2 via clips. An inkjet header 5 is installed on the horizontal rod 3 via two clips. An ink cartridge 52 is also installed at the bottom of the vertical rod 2 via clips. A first ink pump 53 is fixedly connected to the top of the ink cartridge 52. The input end of the first ink pump 53 is connected to and fixedly connected to the bottom end of the ink cartridge 52, and the output end of the first ink pump 53 is connected to and fixedly connected to an ink inlet pipe 51. One end of the ink inlet pipe 51 is connected to and fixedly connected to the inkjet header 5. A crossbar 3 is located below the crossbar 3. The mounting mechanism includes a fixing plate 67, on which a recovery tube 6 is sleeved. The bottom of the recovery tube 6 has multiple filter holes 64. The recovery tube 6 is located directly below the inkjet nozzle 5. A recovery hopper 62 is fixedly connected to the outer wall of the top of the recovery tube 6. The bottom of the recovery hopper 62 is connected to and fixedly connected to an ink outlet tube 63. A second ink pump 55 is provided on the base 1. The input end of the second ink pump 55 is connected to and fixedly connected to the ink outlet tube 63. The output end of the second ink pump 55 is connected to and fixedly connected to an ink supply tube 54. One end of the ink supply tube 54 is connected to and fixedly connected to the top of the ink cartridge 52.
[0021] To address ink waste during ink testing, the system first rotates the recovery tube 6 to the bottom of the inkjet nozzle 5. Then, it moves upwards to engage with the inkjet nozzle 5. Next, the first ink pump 53 and the second ink pump 55 are activated. The first ink pump 53 pumps ink from the ink cartridge 52 through the ink inlet pipe 51 to the inkjet nozzle 5. The ink is then sprayed into the recovery tube 6 via the inkjet nozzle 5. The ink is filtered through the filter holes 64 within the recovery tube 6 and flows into the recovery hopper 62, where impurities are trapped. The second ink pump 55 then pumps the ink from the recovery hopper 62 out through the recovery tube 6 and back into the ink cartridge 52 via the ink delivery pipe 54. This process achieves a cycle of ink ejection, filtration, and recovery. The interaction between the recovery tube 6 and the recovery hopper 62 ensures ink recovery, and the engagement between the inkjet nozzle 5 and the recovery tube 6 prevents the release of volatile gases and environmental pollution.
[0022] Furthermore, such as Figure 3 As shown, the buckle includes a retaining ring 4, which is an adjustable structure, and one end of the retaining ring 4 is installed by a fastening bolt 41.
[0023] During operation, by setting up buckles, in order to install the crossbar 3, ink cartridge 52 and inkjet nozzle 5, the positions of the crossbar 3, ink cartridge 52 and inkjet nozzle 5 are easily adjusted by the cooperation of the retaining ring 4 and the fastening bolt 41.
[0024] Furthermore, such as Figure 1 and Figure 5 As shown, an electric push rod 671 is fixedly connected to the bottom of the retaining ring 4 at one end of the crossbar 3 via a mounting plate. A push plate 672 is fixedly connected to the output end of the electric push rod 671. Two sliding rods 674 are fixedly connected to the top of the push plate 672. A side plate 673 is fixedly connected to the side wall of the electric push rod 671. All sliding rods 674 are slidably connected on the side plate 673.
[0025] During operation, in order to quickly adjust the height of the recovery pipe 6, the electric push rod 671 is activated. The output end of the electric push rod 671 drives the push plate 672 to move, and the push plate 672 drives the recovery pipe 6 to move until it is inserted into and separated from the spray dock 5. During the movement of the push plate 672, the push plate 672 drives the slide rod 674 to move. During the movement of the slide rod 674, the slide rod 674 slides on the side plate 673, and the slide rod 674 limits the push plate 672 to move in the vertical direction.
[0026] Furthermore, such as Figure 5As shown, the mounting mechanism includes a rotating block 678 rotatably connected to the output end of the electric push rod 671. A fixing plate 67 is fixedly connected to the bottom end of the rotating block 678. A second gear 677 is fixedly connected to the outer wall of the rotating block 678. A motor 675 is fixedly connected to the bottom of the push plate 672. A first gear 676 is fixedly connected to the output end of the motor 675. The first gear 676 meshes with the second gear 677.
[0027] During operation, in order to adjust the angle of the recovery tube 6, when recovery is required, the motor 675 is turned on. The output shaft of the motor 675 drives the first gear 676 to rotate, which in turn drives the second gear 677 to rotate. The second gear 677 drives the rotating block 678 to rotate, which in turn drives the fixing plate 67 to rotate. The fixing plate 67 drives the recovery tube 6 to rotate directly below the inkjet nozzle 5, facilitating the insertion and engagement of the recovery tube 6 with the inkjet nozzle 5, thereby recovering the ink.
[0028] Furthermore, such as Figure 2 and Figure 4 As shown, a sealing plug 58 is fixedly attached to the bottom outer wall of the spraying dock 5, and the sealing plug 58 is tightly fitted to the top inner wall of the recovery pipe 6.
[0029] During operation, by setting a sealing plug 58, and the sealing plug 58 being tightly fitted to the inside of the recovery tube 6, a sealed space is formed inside the recovery tube 6 to prevent the volatile gas from escaping.
[0030] Furthermore, such as Figure 3 As shown, a retaining sleeve 57 is fixed to the side wall of the retaining ring 4 on the vertical rod 2 via a connecting rod, and a fixing ring 56 is fixed to the outer wall of the ink cartridge 52. The ink cartridge 52 is inserted into the retaining sleeve 57 and fixed by the fixing ring 56.
[0031] During operation, in order to install and remove the ink cartridge 52, when installation is required, the ink cartridge 52 needs to be inserted into the sleeve 57, and then the ink cartridge 52 is installed by the insertion and cooperation of the fixing ring 56 and the sleeve 57. When the height needs to be adjusted, the height of the corresponding retaining ring 4 needs to be adjusted, so that the height of the ink cartridge 52 can be quickly adjusted.
[0032] Furthermore, such as Figure 2 As shown, an air inlet pipe 66 and an exhaust pipe 65 are connected and fixed to the outer wall of the top end of the recovery pipe 6. One end of the air inlet pipe 66 is connected to a nitrogen source. An air valve is installed on the air inlet pipe 66. A filter element is installed on one end of the exhaust pipe 65. A one-way valve is installed on the exhaust pipe 65.
[0033] During operation, when inkjet printing begins, nitrogen is introduced into the recovery pipe 6 through the air inlet pipe 66. The mixed gas in the recovery pipe 6 is discharged from the exhaust pipe 65 to prevent the mixed gas from entering the ink cartridge 52. After recovery is completed, nitrogen is introduced into the recovery pipe 6 again through the air inlet pipe 66. The nitrogen presses the ink in the recovery pipe 6 into the recovery hopper 62. In addition, the mixed gas is discharged through the exhaust pipe 65 and filtered through the filter element to purify the volatile gases.
[0034] Furthermore, such as Figure 2 As shown, an ink monitoring probe 61 is installed on the outer wall of the recycling tube 6 to monitor the continuity of ink printing and the waveform of the printing.
[0035] During operation, the ink monitoring probe 61 is set to easily detect the coding status of the inkjet terminal 5. If coding problems occur, such as poor continuity or spray tilt, timely feedback is required for adjustment.
[0036] Working Principle: To address ink waste during ink testing, the recovery tube 6 is first rotated to the bottom of the inkjet nozzle 5. Then, the recovery tube 6 is moved upwards and inserted into the inkjet nozzle 5. Next, the first ink pump 53 and the second ink pump 55 are activated. The first ink pump 53 pumps ink from the ink cartridge 52 through the ink inlet pipe 51 to the inkjet nozzle 5. The ink is then sprayed into the recovery tube 6 via the inkjet nozzle 5. The ink is filtered through the filter holes 64 within the recovery tube 6 and flows into the recovery hopper 62, where impurities are trapped. The second ink pump 55 then outputs the ink from the recovery hopper 62 through the recovery tube 6 and delivers it to the ink cartridge 52 via the ink supply pipe 54. This achieves a cycle of ink ejection, filtration, and recovery. The cooperation between the recovery tube 6 and the recovery hopper 62 ensures ink recovery, and the insertion and connection between the inkjet nozzle 5 and the recovery tube 6 prevents the escape of volatile gases, thus avoiding environmental pollution.
[0037] To adjust the angle of the recovery tube 6, when recovery is needed, the motor 675 is activated. The output shaft of the motor 675 drives the first gear 676 to rotate, which in turn drives the second gear 677 to rotate. The second gear 677 then drives the rotating block 678 to rotate, which in turn drives the fixed plate 67 to rotate. The fixed plate 67 then rotates the recovery tube 6 to directly below the inkjet nozzle 5, facilitating the insertion and engagement of the recovery tube 6 with the inkjet nozzle 5, thereby recovering the ink. To quickly adjust the height of the recovery tube 6, the electric push rod 671 is activated. The output end of the electric push rod 671 drives the push plate 672 to move, which in turn drives the recovery tube 6 to move until it engages and disengages with the inkjet nozzle 5. During the movement of the push plate 672, the push plate 672 drives the slide rod 674 to move. The slide rod 674 slides on the side plate 673 during the movement, limiting the push plate 672 to move vertically.
[0038] When inkjet printing begins, nitrogen is introduced into the recovery pipe 6 through the air inlet pipe 66. The mixed gas in the recovery pipe 6 is discharged from the exhaust pipe 65 to prevent the mixed gas from entering the ink cartridge 52. After recovery is completed, nitrogen is introduced into the recovery pipe 6 again through the air inlet pipe 66. The nitrogen presses the ink in the recovery pipe 6 into the recovery hopper 62. In addition, the mixed gas is discharged through the exhaust pipe 65 and filtered through the filter element to purify the volatile gases.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
