Description

Technical Field

[0001] The utility model belongs to the technical field of ink feeding mechanisms, in particular to an ink feeding mechanism for printing. Background Art

[0002] The ink feeding mechanism is a new ink supply method that has only appeared in the field of inkjet printers in recent years. The ink feeding system uses an external ink bottle and is connected to the printer's ink cartridge with a catheter, so that the ink bottle can continuously provide ink to the ink cartridge, which is the so-called "continuous supply". The biggest advantage of the continuous ink supply system is that it is affordable and much cheaper than the original ink. Secondly, the ink supply is large and it is convenient to add ink. Generally, the capacity of one color is 100ml, which is at least 5 times more than the original ink cartridge ink. The quality of its three-continuous supply ink is steadily increasing. Better continuous supply ink will not clog the nozzle. It only needs to be cleaned a few times if the line is broken. This provides a strong guarantee for the survival and development of continuous supply, but the existing ink feeding mechanism cannot meet people's needs. The existing technology avoids the risk of static electricity in the ink grinding process, the structure is practical and reliable, and the safety of the ink grinder is improved, but the ink cannot be stirred, the ink may harden, and the ink gas cannot be filtered and purified.

[0003] A Chinese patent discloses an ink feeding mechanism for digital printing (publication number CN215233612U). The patent is helpful to avoid the situation where the ink is in a static state for a long time and agglomerates by setting a stirring device, a support column, a stirring motor, a fixed frame, a transmission rod and a stirring rod. The air filtering and purification device, the exhaust head, the filter screen, the rotating fixed head and the activated carbon filter chamber are set to help prevent dust from entering the ink tank and the working environment from being polluted. This device is not only simple in structure, but also easy to operate, bringing better prospects for use. However, when the patent is in use, it is impossible to realize the automatic opening and closing of the ink feeding, and it is impossible to control the feeding amount of the ink falling type, thereby affecting the use effect of the ink.

According to the above functions, the whole device includes a storage cylinder 1, the top of which is fixedly sleeved with a receiving bin 2, the inner cavity of which is provided with a filter plate 7 for filtering the ink, the filter plate 7 is a hemispherical concave filter plate 7, which can filter the ink while allowing impurities or larger particles to roll, avoiding accumulation on the surface of the filter plate 7 and causing blockage, the inner cavity of the storage cylinder 1 is provided with a threaded screw 9, the outer thread of which is rotatably sleeved with a spiral block 10 for spirally discharging the ink, the two ends of which are provided with a screw block 10 for spirally discharging the ink. The ends are provided with stirring components, the top end of the threaded screw 9 is provided with a driving mechanism for driving the stirring component to rotate and stir, the bottom end of the threaded screw 9 is provided with a sealing mechanism that cooperates with the spiral block 10 for extrusion, and the sealing mechanism can be squeezed under the spiral movement of the spiral block 10. Since the extrusion and sealing force of the sealing mechanism is less than the thrust of the spiral downward movement of the spiral block 20, the feeding effect can be achieved through the spiral movement of the spiral block 10. A temperature and humidity sensor 3 for detecting the temperature and humidity of the inner cavity of the storage cylinder 1 is installed on one side of the receiving bin 2;

[0024] The sealing mechanism includes a first sleeve block 21, and two movable sealing plates 22 are arranged at the bottom end of the first sleeve block 21. The movable sealing plates 22 are two semicircular plates of the same size and shape. The two can be combined to form a sealing block with the same diameter as the inner cavity of the first sleeve block 21, thereby realizing the sealing of the inner cavity of the first sleeve block 21, and further realizing the sealing of the bottom of the inner cavity of the storage tube 1. A first connecting rod 25 is arranged at the bottom end of the movable sealing plate 22, one end of the first connecting rod 25 is fixedly connected to the bottom of the movable sealing plate 22 through a support rod 23, and the other end of the first connecting rod 25 is fixedly installed on the bottom of the inner cavity of the storage tube 1 through a first hinge seat 29. A thrust assembly for pushing the first connecting rod 25 is arranged on the side of the first connecting rod 25. Under the action of the first connecting rod 25 and the thrust assembly, the movable sealing plate can make the two movable sealing plates 22 fit and seal with each other, thereby realizing the sealing of the bottom of the inner cavity of the storage tube 1 to prevent ink leakage.

By providing the first rotating rod 32, the movable sealing plate 22 and the sleeve 31 can be rotated to meet the needs of flipping;

[0027] like Figure 3-4 As shown, the two support rods 23 are fixedly connected to the first connecting rod 25 bracket through the first fixed rod 24, and the first connecting rod 25 is rotatably connected to the first hinge seat 29 through the second rotating rod 30. Under the action of the first fixed rod 24 and the second rotating rod 30, the two ends of the first connecting rod 25 can be connected so that one end of the first connecting rod 25 rotates in a circle along the other end to achieve the purpose of rotation.

[0028] Example 2: Figure 1-3As shown, the driving mechanism includes a first rotating block 15 that is rotatably sleeved with the top of the threaded screw 9, a first conical tooth 19 is provided at the bottom end of the first rotating block 15, the first conical tooth 19 is fixedly sleeved on the outer periphery of the top end of the threaded screw 9, the side of the first conical tooth 19 is meshedly connected with a second conical tooth 17, the side of the second conical tooth 17 is meshedly connected with a third conical tooth 16, the inner cavity of the second conical tooth 17 is rotatably sleeved with a third rotating rod 18, and the end of the third rotating rod 18 away from the second conical tooth 17 The rotating sleeve is connected to the bottom inner cavity of the first rotating block 15, and the side of the third conical tooth 16 is fixedly sleeved with a rotating shaft 8. Under the action of the first conical tooth 19, the second conical tooth 17 and the third conical tooth 16, power transmission can be realized, and the horizontal rotational force is converted into the vertical rotational force, thereby realizing the rotation requirement of the threaded screw 9. The end of the rotating shaft 8 away from the third conical tooth 16 is fixedly connected to the motor 6. The motor 6 provides power support for the rotation of the driving mechanism, and the motor 6 is fixedly installed on the side of the receiving bin 2.

[0029] like Figure 2-3 As shown, the stirring assembly includes a limit block 20 fixedly sleeved on the periphery of the threaded screw 9, a plurality of second connecting rods 11 are fixedly connected to the side of the limit block 20, a scraper 14 is fixedly connected to the end of the second connecting rod 11 away from the limit block 20, a large stirring rod 12 is arranged on the periphery of the second connecting rod 11, a plurality of small stirring rods 13 are fixedly connected to the periphery of the large stirring rod 12, under the action of the large stirring rod 12 and the small stirring rod 13, the ink in the inner cavity of the storage cylinder 1 can be stirred to improve the stirring effect, the small stirring rod 13 and the end of the second connecting rod 11 away from the limit block 20 are also provided with a scraper 14 for hanging material on the inner wall of the storage cylinder 1, the scraper 14 is evenly arranged in the inner cavity of the storage cylinder 1, the inner wall of the storage cylinder 1 can be evenly scraped, the scraping effect is improved, cleaning is convenient, and ink waste is reduced.

[0030] like Figure 1-2 As shown, the side of the storage tube 1 is fixedly sleeved with an external interface 5, and the storage tube 1 is fixedly connected to the temperature and humidity sensor 3 through a sensing rod 4. By setting the temperature and humidity sensor 3, the temperature and humidity of the inner cavity of the storage tube 1 can be monitored in real time, thereby improving the understanding of the ink and facilitating use. When in use, by reasonably using the external interface 5, the demand for reducing the humidification of the inner cavity of the storage tube 1 can be achieved.

[0031] Working principle: When the device needs to be used, the mixed ink can first be introduced into the inner cavity of the storage tube 1 for storage. Before entering the inner cavity of the storage tube through the receiving bin 2, it will be filtered through the filter plate 7 to remove larger impurities or incompletely mixed particles in the ink, and the temperature and humidity of the inner cavity of the storage tube 1 are monitored through the temperature and humidity sensor 3 to prevent the temperature and humidity of the inner cavity of the storage tube 1 from changing, which will lead to the evaporation of water in the ink, reduce the drying and condensation of the ink, avoid the difficulty of feeding during use, and thus affect the use effect, and humidify and cool down the ink through the external interface 5 as needed; when the ink needs to be used, the motor 6 can be driven to drive the rotating shaft 8 to rotate, and then drive the third cone gear 16, the second cone gear 16 and the third cone gear 16 in turn. The tooth 17 and the first conical tooth 19 rotate, and the rotation of the first conical tooth 19 can drive the threaded screw 9 to rotate, and then drive the limit block 20 to rotate. The rotation of the limit block 20 can drive the stirring component to stir the ink in the inner cavity of the storage cylinder 1. During the stirring process, the inner wall of the storage cylinder 1 can be scraped to prevent the ink from drying and solidifying, causing waste of ink. At the same time, when the threaded screw 9 rotates, it can drive the spiral block 10 to move in a spiral manner. When the spiral block 10 moves down and contacts the top of the movable sealing plate 22 and presses it down, the supporting force of the sealing mechanism will be less than the downward pressure of the spiral block 20, so that the movable sealing plate 22 is flipped open, so as to realize the falling of the ink and then meet the feeding needs.

[0032] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
