Description

Technical Field

[0001] This utility model relates to the field of ink technology, and in particular to an ink filtering device for a printer. Background Technology

[0002] Ink is an important material used in printing. It is used to print or spray patterns and text onto a substrate. Ink contains pigments, solvents, resins and additives. These components are uniformly mixed and repeatedly rolled to form a viscous, colloidal fluid.

[0003] When using a printer, ink is used for printing. Ensuring the quality and purity of the ink is crucial for obtaining high-quality printed products. Since impurities such as iron filings may be mixed into the ink during the manufacturing process, they will affect the quality of the printed products during printing. Therefore, the ink needs to be filtered. During the filtration process, the filter plate will reduce its filtration effect over a long period of use, causing the ink to flow more slowly. This not only affects printing efficiency but may also cause printing machine malfunctions. Furthermore, when adsorbing iron filings, the iron filings filtered on the filter plate must be repeatedly adsorbed to ensure sufficient adsorption. At the same time, in order to ensure that the internal substances of the ink are evenly mixed when it flows out, additional stirring or mixing devices are required. All of these require additional drive sources, thereby increasing the energy consumption of the device. Utility Model Content

[0004] The purpose of this invention is to address the problem in existing technologies where printers require ink for printing, and ensuring the quality and purity of the ink is crucial for obtaining high-quality printed products. Since impurities such as iron filings may be mixed into the ink during manufacturing, affecting the quality of the printed product, ink filtration is necessary. However, during filtration, the filter plate's filtration efficiency decreases over time, leading to slower ink flow. This not only affects printing efficiency but may also cause printer malfunctions. Furthermore, when adsorbing iron filings, the filter plate must be repeatedly used to ensure sufficient adsorption. Additionally, to ensure uniform mixing of the ink components during flow, extra stirring or mixing devices are required, all of which necessitate additional power sources, thus increasing the device's energy consumption.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an ink filtering device for a printer, comprising a housing, an ink inlet pipe and an ink outlet pipe fixedly connected to the top and bottom of the housing respectively, a sealing plate connected to one side of the housing by bolts, an installation groove formed on one side of the housing, a filter plate fixedly connected to the inner cavity of the housing, two reciprocating lead screws provided in the inner cavity of the housing, threaded sleeves fitted around the outer rings of the reciprocating lead screws, a fixing plate fixedly connected to the bottom of one of the threaded sleeves, and limit grooves formed on both sides of the fixing plate. The inner cavity is equipped with a magnetic plate, and limit blocks are fixedly connected to both sides of the magnetic plate. A slider is fixedly connected to one side of the fixed plate. A sliding groove adapted to the slider is opened on one side of the inner cavity of the housing. One end of the reciprocating screw extends through the inner wall of the adjacent housing to the inner cavity of the mounting groove and is fixedly connected to a pulley. The two pulleys are connected by a belt winding together. A scraper and a moving block are fixedly connected to the top and bottom of another screw sleeve, respectively. A round rod penetrating the side wall of the moving block is fixedly connected to the inner cavity of the housing. Several corrugated plates are fixedly connected to the bottom of the moving block.

[0006] Preferably, the outer surface of the limiting block engages with the inner cavity of the corresponding limiting groove, and the outer surface of the slider slides in a sliding connection with the inner cavity of the sliding groove. Specifically, the slider and the sliding groove are designed so that one of the threaded sleeves does not rotate with the reciprocating screw, but moves along the reciprocating screw.

[0007] Preferably, one end of the reciprocating lead screw is rotatably connected to the inner wall of the adjacent housing via a rotating shaft. Specifically, the rotating shaft is designed to make the reciprocating lead screw rotate more smoothly.

[0008] Preferably, a motor is fixedly installed in the inner cavity of the mounting groove, and the output shaft of the motor is connected to one end of an adjacent pulley for transmission. Specifically, the motor provides power to rotate the adjacent pulley.

[0009] Preferably, one side of the scraper is in contact with one side of the adjacent filter plate. Specifically, by setting the scraper, the scraper moves back and forth over the bottom of the filter plate, which can prevent impurities in the ink from clogging the filter plate and accelerate the flow rate of the ink.

[0010] Preferably, a connecting frame is fixedly connected to both sides of the top of the fixing plate, and a fixing rod is provided in the inner cavity of the connecting frame. The top of the fixing rod extends through the top of the inner cavity of the corresponding connecting frame to the top of the connecting frame.

[0012] Preferably, the outer ring of the fixed plug is fitted with a spring, and the outer ring of the fixed plug is fitted with a fixed baffle. One end of the spring abuts against the top of the inner cavity of the corresponding connecting bracket, and the other end of the spring abuts against one side of the corresponding fixed baffle. Specifically, through the setting of the spring, the elastic force of the spring can drive the fixed plug to move to the inner cavity of the fixed plug hole.

[0022] 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.

[0023] Example 1, such as Figure 1 - Figure 4 As shown, this utility model provides an ink filtering device for a printer, including a housing 1. An ink inlet pipe 3 and an ink outlet pipe 4 are fixedly connected to the top and bottom of the housing 1, respectively. A sealing plate 2 is bolted to one side of the housing 1. An installation groove 5 is provided on one side of the housing 1. A filter plate 18 is fixedly connected to the inner cavity of the housing 1. Two reciprocating screws 9 are provided in the inner cavity of the housing 1. A threaded sleeve 12 is fitted around the outer ring of each reciprocating screw 9. A fixing plate 13 is fixedly connected to the bottom of one of the threaded sleeves 12. Limiting grooves 15 are provided on both sides of the fixing plate 13. A magnetic plate 14 is provided in the inner cavity of the fixing plate 13. Limiting blocks 10 are fixedly connected to both sides of the iron plate 14. A slider 19 is fixedly connected to one side of the fixed plate 13. A sliding groove 20 adapted to the slider 19 is opened on one side of the inner cavity of the housing 1. One end of the reciprocating screw 9 extends through the inner wall of the adjacent housing 1 to the inner cavity of the mounting groove 5 and is fixedly connected to a pulley 7. The two pulleys 7 are connected by a belt winding. The top and bottom of another screw sleeve 12 are fixedly connected to a scraper 25 and a moving block 16, respectively. A round rod 11 that penetrates the side wall of the moving block 16 is fixedly connected to the inner cavity of the housing 1. Several wave plates 17 are fixedly connected to the bottom of the moving block 16.

[0024] In this embodiment, during use, ink flows into the inner cavity of the housing 1 through the ink inlet pipe 3. The operator starts the motor 6, which drives the adjacent pulleys 7 to rotate. With the help of the belts, the two pulleys 7 rotate together, driving the two reciprocating screws 9 to rotate together. The reciprocating screws 9 drive the screw sleeve 12 to move back and forth. The back-and-forth movement of the screw sleeve 12 drives the magnetic plate 14 inside the fixed plate 13 to move. As the screw sleeve 12 moves back and forth, the magnetic plate 14 also moves back and forth, ensuring that it can cover the entire upper area of ​​the filter plate 18, thereby effectively adsorbing iron filings. The scraper 25 moves back and forth over the bottom of the filter plate 18, preventing impurities in the ink from clogging the filter plate 18 and accelerating the ink flow. When the wave plate 17 moves back and forth at the output speed, it agitates the ink, making the ink flow more uniform and ensuring that the ink flows out of the ink outlet pipe 4 more evenly. Through structural design, iron filings mixed in the ink are fully adsorbed, ensuring the quality and purity of the ink and guaranteeing the printing quality of the printed products. During ink filtration, the filter plate 18 is continuously scraped to maintain its filtration efficiency, ensuring ink flow and guaranteeing the continuous and normal operation of the printing press and printing efficiency. Furthermore, when the ink flows out, the internal substances of the ink flow evenly, ensuring stable ink quality. Moreover, only one drive source is used for driving, reducing the energy consumption of the device and saving energy.

[0025] Example 2, as Figure 1 - Figure 4 As shown, the outer surface of the limiting block 10 is engaged with the inner cavity of the corresponding limiting groove 15, and the outer surface of the slider 19 is slidably connected to the inner cavity of the sliding groove 20.

[0026] One end of the reciprocating lead screw 9 is rotatably connected to the inner wall of the adjacent housing 1 via a rotating shaft.

[0027] The motor 6 is fixedly installed in the inner cavity of the mounting slot 5, and the output shaft of the motor 6 is connected to one end of the adjacent pulley 7 for transmission.

[0028] One side of the scraper 25 is attached to one side of the adjacent filter plate 18.

[0029] Both sides of the top of the fixed plate 13 are fixedly connected to the connecting frame 21. The inner cavity of the connecting frame 21 is provided with a fixing rod 22. The top of the fixing rod 22 extends through the top of the inner cavity of the corresponding connecting frame 21 to the top of the connecting frame 21.

[0030] The top of the limiting block 10 is provided with a fixing hole 8, and the bottom of the fixing rod 22 passes through the top of the fixing plate 13 and is inserted into the inner cavity of the corresponding fixing hole 8.

[0031] A spring 23 is fitted around the outer ring of the fixed insertion rod 22, and a fixed baffle 24 is fitted around the outer ring of the fixed insertion rod 22. One end of the spring 23 abuts against the top of the inner cavity of the corresponding connecting bracket 21, and the other end of the spring 23 abuts against one side of the corresponding fixed baffle 24.

[0032] In this embodiment, during use, when a person pulls the fixed insertion rod 22, the spring 23 deforms due to its elasticity, and applies force to the fixed insertion rod 22, causing it to move upward. The fixed insertion rod 22 moves out of the inner cavity of the fixed insertion hole 8, allowing the person to remove the limiting block 10 and the magnetic plate 14 together, thereby removing the iron filings on the magnetic plate 14. When the person releases the fixed insertion rod 22, the spring 23 returns to its original state, and the elastic force of the spring 23 can move the fixed insertion rod 22 into the inner cavity of the fixed insertion hole 8, completing the installation of the limiting block 10 and the magnetic plate 14. The quick removal of the magnetic plate 14 can greatly reduce the time required to clean the iron filings, eliminating the need for a long time to remove the magnetic plate 14, thus shortening the preparation time for reuse and not affecting the use of the equipment, thereby further improving the efficiency of the entire workflow.

[0033] Working principle

[0034] In use, ink flows into the inner cavity of the housing 1 through the ink inlet pipe 3. The operator starts the motor 6, which drives the adjacent pulleys 7 to rotate. With the help of the belts, the two pulleys 7 rotate together, driving the two reciprocating screws 9 to rotate as well. The reciprocating screws 9 drive the screw sleeve 12 to move back and forth. The back-and-forth movement of the screw sleeve 12 drives the magnetic plate 14 inside the fixed plate 13 to move. As the screw sleeve 12 moves back and forth, the magnetic plate 14 also moves back and forth, ensuring that it can cover the entire upper area of ​​the filter plate 18, thereby effectively adsorbing iron filings. The scraper 25 moves back and forth over the bottom of the filter plate 18 to prevent impurities in the ink from clogging it. The filter plate 18 accelerates the ink flow rate. As the corrugated plate 17 moves back and forth, it agitates the ink, making its flow more uniform and ensuring a more even ink flow from the ink outlet pipe 4. Through its structural design, it effectively adsorbs iron filings mixed in the ink, guaranteeing ink quality and purity, and ensuring the printing quality of the printed materials. Furthermore, during ink filtration, the filter plate 18 is continuously scraped to maintain its filtration efficiency, ensuring ink flow and guaranteeing continuous and normal operation of the printing press and printing efficiency. Moreover, the uniform flow of internal substances within the ink during outflow ensures the ink's purity. Stable quality and the use of only one drive source reduce device energy consumption and save energy. The magnetic plate 14 adsorbs iron filings from the ink. When personnel need to clean the iron filings adsorbed on the magnetic plate 14, quick disassembly of the magnetic plate 14 for cleaning is crucial. Tedious disassembly not only requires a significant amount of time but also increases printer downtime, affecting usability and reducing printing efficiency. When a person pulls the fixing rod 22, the elasticity of the spring 23 causes the spring 23 to deform, applying force to the fixing rod 22, causing it to move upwards. As rod 22 moves out of the inner cavity of fixed insertion hole 8, personnel can remove the limiting block 10 and the magnetic plate 14 together, thereby removing iron filings from the magnetic plate 14. When personnel release the fixed insertion rod 22, spring 23 returns to its original state. The elastic force of spring 23 can drive the fixed insertion rod 22 to move into the inner cavity of fixed insertion hole 8, completing the installation of the limiting block 10 and the magnetic plate 14. Quick disassembly of magnetic plate 14 can greatly reduce the time required to clean iron filings. Personnel do not need to spend a long time disassembling magnetic plate 14, which shortens the preparation time for reuse and does not affect personnel use, thereby further improving the efficiency of the entire workflow.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
