Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to an ink reminder mechanism for inkjet printers. Background Art

[0002] Inkjet printers are a type of large printer series product. They are not as clear as printing and photo machines, but the clarity of the inkjet printers launched now is greatly improved. Most inkjet printers use solvent-based or UV-curable inks, among which solvent-based inks have a strong odor and are corrosive. During the printing process, the ink penetrates into the interior of the printing material through corrosion, making the image less likely to fade, so it has the characteristics of being waterproof, UV-resistant, and scratch-resistant.

[0003] Ink is an important resource necessary for the normal operation of an inkjet printer. If the ink is exhausted and not replaced in time, the inkjet printer cannot operate normally, resulting in production interruption. At the same time, if the ink is exhausted and not replaced in time, the nozzle will be in a dry state. A dry nozzle may be damaged or clogged, affecting the quality of inkjet printing and even damaging the equipment. In view of this technical problem, the present application proposes an ink reminder mechanism for an inkjet printer. Utility Model Content

[0028] Embodiment 1:

[0029] Reference Figure 1-4 An ink reminder mechanism for an inkjet printer includes an ink tank 1, a transmitter 4 is fixedly connected to the inner wall of the rear side of the ink tank 1, a receiver 5 is fixedly connected to the inner wall of the front side of the ink tank 1, two rotating shafts 6 are rotatably connected to the inner wall of the ink tank 1, a volute spring 12 is arranged at the right end of the right rotating shaft 6, a winding roller 7 is connected to the adjacent ends of the two rotating shafts 6 through an insert block 15 and a slot 17, a coating shielding cloth 8 is arranged on the outer wall of the winding roller 7, and a floating plate 9 is connected to the bottom end of the coating shielding cloth 8 through two locking blocks 11, A spiral spring 12 is located on the outer wall of the right end of the right rotating shaft 6, and a fixed shell 13 is provided at the right end of the right rotating shaft 6. One end of the spiral spring 12 is fixedly connected to the outer wall of the right rotating shaft 6, and the other end of the spiral spring 12 is fixedly connected to the inner wall of the fixed shell 13. Four sliding rods 10 are fixedly connected to the inner wall of the bottom side of the ink tank 1. The floating plate 9 is slidably connected to the outer walls of the four sliding rods 10. The top side of the ink tank 1 is fixedly connected to the inkjet head 2. The rear outer wall of the ink tank 1 and the rear outer wall of the inkjet head 2 are connected through a connecting pipe 3.

[0030] Specifically, a water pump is installed inside the ink tank 1, and the ink inside the ink tank 1 is extracted through the water pump and the connecting pipe 3 to supply the ink to the inkjet head 2 for inkjet printing. When the ink level inside the ink tank 1 drops, the float plate 9 is driven to slide up and down on the four slide bars 10, pulling the shielding coating cloth 8 to move downward. When the liquid level drops less, the light beam emitted by the transmitter 4 passes through the gap at the lower end of the shielding coating cloth 8 and is shot onto the receiver 5. When the liquid level drops to a certain distance, the top of the shielding coating cloth 8 driven by the transmitter 4 blocks the light beam of the transmitter 4, and the receiver 5 cannot receive the light beam, resulting in an alarm to remind the need to replenish ink, thereby avoiding the influence of insufficient ink level on the inkjet printing effect and equipment. At the same time, when replenishing ink, the ink level inside the ink tank 1 rises, driving the float plate 9 to rise, and the spiral spring 12 is wound up to drive the rotating shaft 6 and the winding roller 7 to rotate, and the shielding coating cloth 8 is wound up, thereby avoiding the ink inside the ink tank 1 from being lost in time or for a long time, resulting in damage to the equipment.

[0031] Embodiment 2:

[0032] As one of the optimized structural designs for Example 1, Figure 1-Figure 4 As shown, there are slots 17 located at the proximal ends of the two rotating shafts 6 and two plug blocks 15 located at the left and right ends of the winding roller 7, the two plug blocks 15 are respectively arranged inside the two slots 17, the outer walls of the proximal ends of the two rotating shafts 6 are threadedly connected with lock shells 14, the proximal ends of the two lock shells 14 are respectively threadedly connected to the left and right ends of the shielding paint cloth 8, the lock block 11 located on the top side of the floating plate 9, the bottom end of the shielding paint cloth 8 is arranged inside the lock block 11, and the lock block 11 is threadedly connected with a positioning bolt 16;

[0033] Specifically, when the shielding coating cloth 8 is damaged, the shielding coating cloth 8 can be removed from the floating plate 9 by the cooperation between the locking block 11 and the positioning bolt 16, and then the lock shell 14 can be rotated to make the lock shell 14 detach from the connection between the rotating shaft 6 and the winding roller 7, so that the winding roller 7 can be detached from the two rotating shafts 6 to replace the shielding coating cloth 8, and then the plug block 15 is inserted into the inside of the slot 17, and then the lock shell 14 is stuck in the connection between the rotating shaft 6 and the winding roller 7 to connect the winding roller 7 and the two rotating shafts 6, and then the shielding coating cloth 8 is installed on the floating plate 9 by the locking block 11 and the positioning bolt 16, so that the damaged shielding coating cloth 8 can be replaced to avoid the damaged shielding coating cloth 8 from affecting the measurement of the ink liquid level.

[0034] Working principle: by installing a water pump inside the ink tank 1, the ink inside the ink tank 1 is extracted through the water pump and the connecting pipe 3 to supply the ink to the inkjet head 2 for inkjet printing. When the ink level inside the ink tank 1 drops, it drives the float plate 9 to slide up and down on the four slide bars 10, pulling the shielding coating cloth 8 to move down. When the liquid level drops less, the light beam emitted by the transmitter 4 passes through the gap at the lower end of the shielding coating cloth 8 and shoots onto the receiver 5. When the liquid level drops to a certain distance, the top of the shielding coating cloth 8 drives the light beam of the transmitter 4 to be blocked, and the receiver 5 cannot receive the light beam, resulting in an alarm to remind that ink needs to be replenished, so as to avoid the ink level being too low and causing the inkjet printing effect and equipment to be affected. At the same time, when replenishing ink, the ink level inside the ink tank 1 rises, driving the float plate 9 to rise, and through the vortex The spring 12 is wound up to drive the rotating shaft 6 and the winding roller 7 to rotate, and the shielding coating cloth 8 is wound up to avoid the ink inside the ink tank 1 from being lost in time and for a long time, which may cause damage to the equipment. At the same time, when the shielding coating cloth 8 is damaged, the shielding coating cloth 8 can be removed from the floating plate 9 through the cooperation between the locking block 11 and the positioning bolt 16, and then the lock shell 14 is rotated to make the lock shell 14 detach from the connection between the rotating shaft 6 and the winding roller 7, and then the plug block 15 is inserted into the inside of the slot 17, and then the lock shell 14 is stuck in the connection between the rotating shaft 6 and the winding roller 7, and then the shielding coating cloth 8 is installed on the floating plate 9 through the locking block 11 and the positioning bolt 16, so as to realize the replacement of the damaged shielding coating cloth 8 and avoid the damaged shielding coating cloth 8 affecting the measurement of the ink liquid level.
