Description

Technical Field

[0001] This invention belongs to the field of inkjet printing technology, specifically relating to an industrial digital inkjet printing robot. Background Technology

[0002] An industrial digital inkjet printing robot is a high-precision industrial robot arm equipped with an "inkjet printer head". Unlike traditional printers that can only print on a flat sheet of paper, it can hold the printhead and perform direct and precise color printing on three-dimensional, irregular, and curved surfaces.

[0003] Patent CN120921818A discloses a modular intelligent printing robot, including a printing robot body and a sealing part. The sealing part includes multiple sealing sections that slide within the inkjet nozzle, sealing it and occupying the space at the bottom of the nozzle. The outlet direction of the spiral hole faces the inner wall of the nozzle. When the printing robot body heats the ink inside, the ink is ejected through the spiral hole, causing the ink inside the nozzle to spiral and lift up any sediment, circulating with the ink within the printing robot body. When the sealing section leaves the nozzle, space is left for the ink, preventing it from dripping due to pressure. The special design of the spiral hole in this invention creates a rotational force when the ink is ejected, driving the ink inside the nozzle to spiral and form a vortex, lifting up sediment and circulating with the ink within the printing robot body. This effectively prevents ink particles from adhering, reduces ink volume, and prevents printing spots, thus improving printing quality. The aforementioned devices struggle to guarantee inkjet quality during extended operation, resulting in inconsistent printing depth and color variations, leading to reduced print quality. Furthermore, they are difficult to protect when stopped, impacting efficiency for subsequent runs and increasing setup costs. Ink leakage is also a concern after periods of downtime, eventually affecting pressure output and overall device performance. Therefore, an industrial digital inkjet printing robot is proposed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide an industrial digital inkjet printing robot to solve the problems of difficulty in ensuring inkjet quality during long-term operation, difficulty in protecting the device when it stops operating, and the tendency for ink leakage to occur after a period of downtime, which eventually affects the pressure output of the device.

[0005] To achieve the above objectives, the present invention provides an industrial digital inkjet printing robot, comprising: a chassis, a robotic arm fixedly connected to the top surface of the chassis, a secondary ink cartridge disposed on the end face of the robotic arm, an inkjet mechanism disposed below the secondary ink cartridge, and a protective mechanism disposed on the outside of the inkjet mechanism. The inkjet mechanism includes a fixing ring, which is fixedly connected to the surface of the robotic arm. An inkjet tube is fixedly connected inside the fixing ring. A baffle is fixedly connected to the inner wall of the inkjet tube. A base plate is fixedly connected to the inner wall of the baffle. A motor is installed inside the base plate. A main shaft is fixedly connected to the output end of the motor.

[0006] In one or more embodiments of the present invention, a drive plate is fixedly connected to the front end of the main shaft, and the front end of the drive plate is in contact with the rear side of the baffle. A bidirectional spiral groove is formed on the circumferential surface of the main shaft, and a movable ring is movably connected to the circumferential surface of the main shaft. When the device is running, the output end of the motor set inside the fixed ring drives the main shaft to rotate. The rotation of the main shaft causes the drive plate to rotate close to the rear side of the baffle. Since inkjet nozzles are formed on both the surface of the baffle and the surface of the drive plate, when the ink outlet on the drive plate rotates to coincide with the ink outlet on the surface of the baffle, the device starts to spray ink. This process is repeated, and the output end of the motor set inside the fixed ring drives the drive plate to rotate, realizing intermittent ink spraying of the device. Intermittent ink spraying can keep the ink path slightly circulating, the ink concentration is uniform, and the printing will not have uneven depth or color difference, ensuring long-term printing stability and improving printing quality and equipment reliability.

[0007] In one or more embodiments of the present invention, a limiting ring is fixedly connected to the circumferential surface of the movable ring, a guide groove is provided on the inner wall of the inkjet tube, the surface of the limiting ring is slidably connected to the guide groove provided on the inner wall of the inkjet tube, and an anti-foaming ring is fixedly connected to the surface of the limiting ring. When the main shaft rotates, due to the limiting ring fixedly connected to the movable ring, the rotation of the main shaft drives the movable ring to move on the circumferential surface of the main shaft. The movement of the main shaft drives the limiting ring to slide on the inner wall of the fixed ring. The sliding of the limiting ring drives the anti-foaming ring to move. The rotation of the main shaft drives the movement of the anti-foaming ring, thereby achieving the cutting effect on the air bubbles in the ink stored in the fixed ring, preventing small air bubbles from agglomerating into large air bubbles, eliminating the hidden danger of air bubbles in all directions, and preventing faults such as ink breakage, ink splatter, printing color difference, and line defects caused by air bubbles. This ensures smooth ink flow, uniform and stable ink supply, improves inkjet printing accuracy and quality, and ensures the reliability of the equipment for long-term continuous operation.

[0008] In one or more embodiments of the present invention, the protective mechanism includes a trigger plate, which is fixedly connected to the front side of the limiting ring. The surface of the trigger plate is in contact with the inner wall of the inkjet tube. A sliding groove is provided on the front side of the baffle, and a guide post is fixedly connected to the inner wall of the sliding groove.

[0009] In one or more embodiments of the present invention, a second baffle is slidably connected to the cylindrical surface of the guide post by a spring. The rear side of the second baffle is slidably connected to the front side of the first baffle. An ink outlet is provided on the surface of the first baffle, and the ink outlet is located within the movement range of the second baffle. The second baffle is located within the movement range of the trigger plate. When the device stops running, the main shaft rotates, causing the limiting ring to move forward. The limiting ring causes the trigger plate to move forward. When the trigger plate moves to the working range of the second baffle, the trigger plate causes the second baffle to move along the surface of the second baffle. The inclined surface of the guide column slides towards the ink outlet on the circumference of the guide column until the second baffle completely blocks the ink outlet on the surface of the first baffle. The rotation of the main shaft drives the second baffle to move, thus protecting the ink outlet after the device stops running. By blocking the ink outlet with the second baffle, external dust, impurities and airflow can be isolated from contact with the nozzle, preventing ink from drying and forming a skin that can clog the printhead. At the same time, it can prevent the first baffle from being accidentally bumped and damaged, reduce the pollution caused by ink dripping and leakage, keep the ink outlet clean, and allow for quick and stable ink spraying the next time the machine is turned on, thus reducing failure and debugging costs.

[0010] In one or more embodiments of the present invention, the protective mechanism further includes a fixing block 1, which is fixedly connected to the surface of the trigger plate. A motor is provided on the inner wall of the fixing block 1, and a rocker arm 1 is fixedly connected to the output end of the motor. The end of the rocker arm 1 away from the fixing block 1 is hinged to a fixing block 2 by a torsion spring. A baffle plate is fixedly connected to the surface of the fixing block 2. When the device is running, the motor inside the fixing block 1 is started, and the output end of the motor drives the rocker arm 1 to rotate. The rotation of the rocker arm 1 drives the fixing block 2 to make a circular motion around the rotation center of the rocker arm 1. The movement of the fixing block 2 drives the baffle plate to move until the inner wall of the baffle plate is in close contact with the surface of the fixing ring. The movement of the baffle plate driven by the motor inside the fixing block 1 achieves the protective effect of the ejected ink droplets when the device is running. The extended baffle plate can effectively block the interference of external airflow on the inkjet process, prevent the ink droplets from being blown off course and scattered by the airflow, ensure that the flight trajectory of the ink droplets is straight and accurate, greatly improve the printing clarity and color registration accuracy, further ensure inkjet stability, and make the equipment more reliable for long-term operation.

[0011] In one or more embodiments of the present invention, the secondary ink cartridge includes an ink cartridge, the ink cartridge is fixedly connected to the rear side of the fixing ring, a sealing rod is fixedly connected to the inner wall of the fixing ring, and a baffle three is fixedly connected to the telescopic end of the sealing rod, the baffle three being arranged on the movement trajectory of the baffle plate.

[0012] In one or more embodiments of the present invention, the baffle three is slidably connected to the inner wall of the fixed ring, the baffle three is in contact with the front side of the ink cartridge, and a limit post is fixedly connected to the surface of the baffle three. The limit post is slidably connected to the inner wall of the fixed ring by a spring. When the device stops running, the output end of the motor provided inside the fixed block one reverses to drive the rocker arm one to rotate. The rotation of the rocker arm one drives the fixed block two to make a circular motion around the rotation center of the rocker arm one. The fixed block two drives the baffle plate to rotate. When the baffle plate rotates to the working range of the baffle three, the baffle plate squeezes and drives the baffle plate to rotate. When plate three moves inward, baffle three moves the limiting post inward, and simultaneously baffle three moves the sealing rod inward until baffle three contacts the circumferential surface of the main shaft. The rotation of the baffle plate moves baffle three along the inner wall of the fixed ring, thus achieving the effect of preventing leakage of ink stored inside the ink box after the device stops running. When the machine stops, it can block the leakage channel formed by gravity and pressure difference in the ink path, preventing ink from overflowing or dripping. At the same time, it stabilizes the internal pressure of the ink path and reduces abnormal pressure leakage caused by air intake, eliminating leakage problems such as ink dripping and leakage during shutdown from the source, and avoiding contamination of equipment and workpieces.

[0013] In one or more embodiments of the present invention, the secondary ink cartridge further includes a fixing block four, which is fixedly connected to the rear side of the baffle three. A rocker arm two is rotatably connected to the surface of the fixing block four, and a fixing block five is rotatably connected to the end of the rocker arm two away from the fixing block four.

[0014] In one or more embodiments of the present invention, a turntable is fixedly connected to the rear end of the fixed block five, and a stirring plate is rotatably connected to the cylindrical surface of the turntable. A one-way spiral groove is provided on the inner wall of the ink cartridge, and the stirring plate is spirally connected to the inner wall of the ink cartridge. While the baffle three slides, the baffle three drives the fixed block four to move. The movement of the fixed block four drives the rocker arm two to rotate. The rotation of the rocker arm two drives the fixed block five to move backward. The movement of the fixed block five drives the turntable to move. The movement of the turntable drives the stirring plate to move. While the stirring plate moves backward, it rotates along the one-way spiral groove provided on the inner wall of the ink cartridge. The movement of the baffle three drives the stirring plate to move backward and rotate, thereby realizing the stirring of the residual ink in the ink cartridge. This can effectively prevent pigment from settling and separating, ensure uniform and stable ink concentration and viscosity, avoid problems such as printing color difference, ink breakage, and nozzle clogging caused by uneven ink, ensure stable ink supply, and improve the inkjet quality and operational reliability of the device.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the coordinated operation of the fixed ring, inkjet tube, baffle plate, base plate, main shaft, drive plate, movable ring, limit ring, and defoaming ring, the output end of the motor inside the fixed ring drives the drive plate to rotate, realizing intermittent ink output. Intermittent inkjet keeps the ink path slightly circulating, ensuring uniform ink concentration and preventing uneven printing or color differences. This guarantees stable printing over a long period, improves print quality and equipment reliability. The rotation of the main shaft drives the movement of the defoaming ring, which cuts the air bubbles in the ink stored in the fixed ring, preventing small air bubbles from accumulating into large air bubbles. This comprehensively eliminates the potential for air bubbles, preventing problems such as ink interruption, ink splatter, color difference, and incomplete lines caused by air bubbles. It ensures smooth ink flow, uniform and stable ink supply, improves inkjet printing accuracy and quality, and ensures the reliability of the equipment for long-term continuous operation.

[0016] 2. Through the coordinated operation of the trigger plate, guide column, baffle two, fixed block one, rocker arm one, fixed block two, and wind deflector, the rotation of the main shaft drives the movement of baffle two, thus protecting the inkjet nozzle after the device stops operating. By blocking the ink outlet with baffle two, external dust, impurities, and airflow can be isolated from contact with the nozzle, preventing ink from drying and forming a skin that could clog the printhead. At the same time, it avoids accidental damage to baffle one, reducing pollution caused by ink dripping and leakage, keeping the ink outlet clean, and allowing for quick and stable inkjet printing upon the next startup, thus reducing failure and debugging costs. The motor inside fixed block one drives the movement of the wind deflector, achieving the effect of protecting the ejected ink droplets during device operation. The extended wind deflector can effectively block external airflow from interfering with the inkjet process, preventing ink droplets from being blown off course or scattered by the airflow, ensuring that the ink droplet flight trajectory is straight and accurate, greatly improving printing clarity and color registration accuracy, further ensuring inkjet stability, and making the equipment more reliable for long-term operation.

[0017] 3. Through the coordinated operation of the ink cartridge, sealing rod, limiting post, baffle three, fixing block four, rocker two, fixing block five, turntable, and stirring plate, the rotation of the baffle plate drives the movement of baffle three on the inner wall of the fixing ring. This achieves the effect of preventing leakage of ink stored inside the ink cartridge after the device stops operating. When the machine stops, it can block the leakage channel formed by gravity and pressure difference in the ink path, preventing ink overflow and dripping. At the same time, it stabilizes the internal pressure of the ink path and reduces abnormal pressure leakage caused by air intake. It eliminates leakage problems such as ink dripping and leakage during shutdown from the source, avoiding contamination of equipment and workpieces. The movement of baffle three drives the stirring plate to move backward and rotate, realizing the stirring of residual ink in the ink cartridge. This can effectively prevent pigment from settling and separating, ensuring uniform and stable ink concentration and viscosity, avoiding problems such as printing color difference, ink interruption, and nozzle blockage caused by uneven ink, ensuring stable ink supply, and improving the inkjet quality and operational reliability of the device.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1-8 As shown, one embodiment of the present invention is: an industrial digital inkjet printing robot, including: a chassis 1, a robotic arm 2 fixedly connected to the top surface of the chassis 1, a secondary ink cartridge 5 disposed on the end face of the robotic arm 2, an inkjet mechanism 3 disposed below the secondary ink cartridge 5, and a protective mechanism 4 disposed on the outside of the inkjet mechanism 3. The inkjet mechanism 3 includes a fixing ring 31, which is fixedly connected to the surface of the robotic arm 2. An inkjet tube 32 is fixedly connected inside the fixing ring 31. A baffle 33 is fixedly connected to the inner wall of the inkjet tube 32. A base plate 34 is fixedly connected to the inner wall of the baffle 33. A motor is installed inside the base plate 34. A main shaft 35 is fixedly connected to the output end of the motor.

[0022] The front end of the main shaft 35 is fixedly connected to the active plate 36. The front end of the active plate 36 is in contact with the rear side of the baffle 33. A bidirectional spiral groove is opened on the circumferential surface of the main shaft 35. A movable ring 37 is movably connected to the circumferential surface of the main shaft 35. The output end of the motor set inside the fixed ring 31 drives the active plate 36 to rotate, realizing the intermittent ink output of the device. The intermittent inkjet can keep the ink path slightly circulating, the ink concentration is uniform, and the printing will not have uneven depth or color difference, ensuring long-term printing stability and improving printing quality and equipment reliability.

[0023] A limiting ring 38 is fixedly connected to the circumferential surface of the movable ring 37. A guide groove is provided on the inner wall of the inkjet tube 32. The surface of the limiting ring 38 is slidably connected to the guide groove on the inner wall of the inkjet tube 32. An anti-foaming ring 39 is fixedly connected to the surface of the limiting ring 38. The defoaming ring 39 is moved by the rotation of the main shaft 35, which realizes the cutting effect of air bubbles in the ink stored in the fixed ring 31, avoids small air bubbles from aggregating into large air bubbles, eliminates the hidden danger of air bubbles in all directions, and eliminates faults such as ink interruption, ink splatter, printing color difference, and line defects caused by air bubbles. It ensures smooth ink flow, uniform and stable ink supply, improves inkjet printing accuracy and quality, and ensures the reliability of the equipment for long-term continuous operation.

[0024] The protective mechanism 4 includes a trigger plate 41, which is fixedly connected to the front side of the limiting ring 38. The surface of the trigger plate 41 is in contact with the inner wall of the inkjet tube 32. A sliding groove is provided on the front side of the baffle 33, and a guide post 42 is fixedly connected to the inner wall of the sliding groove.

[0025] A second baffle 43 is slidably connected to the cylindrical surface of the guide column 42 via a spring. The rear side of the second baffle 43 is slidably connected to the front side of the first baffle 33. An ink outlet is provided on the surface of the first baffle 33, which is located within the movement range of the second baffle 43. The second baffle 43 is located within the movement range of the trigger plate 41. The main shaft 35 rotates to drive the second baffle 43 to move, thus protecting the ink nozzle after the device stops operating. By blocking the ink outlet with the second baffle 43, external dust, impurities, and airflow can be isolated from contact with the nozzle, preventing ink from drying and forming a skin, which can cause printhead blockage. At the same time, it can prevent the first baffle 33 from being accidentally bumped and damaged, reduce the pollution caused by ink dripping and leakage, keep the ink outlet clean, and allow for quick and stable ink spraying the next time the machine is turned on, thus reducing failure and debugging costs.

[0026] The protective mechanism 4 also includes a fixing block 44, which is fixedly connected to the surface of the trigger plate 41. A motor is installed on the inner wall of the fixing block 44, and a rocker arm 45 is fixedly connected to the output end of the motor. The end of the rocker arm 45 away from the fixing block 44 is hinged to a fixing block 46 via a torsion spring. A baffle plate 47 is fixedly connected to the surface of the fixing block 46. The motor inside the fixing block 44 drives the baffle plate 47 to move, thus achieving the protection effect of the ejected ink droplets during device operation. The extended baffle plate 47 can effectively block the interference of external airflow on the inkjet process, prevent ink droplets from being blown off course and scattered by the airflow, ensure that the trajectory of the ink droplets is straight and accurate, greatly improve the printing clarity and color registration accuracy, further ensure inkjet stability, and make the equipment more reliable for long-term operation.

[0027] Working Principle: During operation, the output of the motor inside the fixed ring 31 drives the main shaft 35 to rotate. The rotation of the main shaft 35 causes the drive plate 36 to rotate against the rear side of the baffle 33. Since inkjet nozzles are provided on both the surface of the baffle 33 and the surface of the drive plate 36, the device begins to spray ink when the ink outlet on the drive plate 36 rotates to coincide with the ink outlet on the surface of the baffle 33. This process repeats, with the output of the motor inside the fixed ring 31 driving the drive plate 36 to rotate, achieving intermittent ink spraying. Intermittent ink spraying keeps the ink path slightly circulating, ensuring uniform ink concentration and preventing uneven printing or color differences. This guarantees stable printing over long periods, improving print quality and equipment reliability. As the main shaft 35 rotates, the limiting ring 38, which is fixedly connected to the movable ring 37, causes the movable ring 37 to move on the circumferential surface of the main shaft 35. The movement of the main shaft 35 causes the limiting ring 38 to slide on the inner wall of the fixed ring 31. The sliding of the limiting ring 38 causes the defoaming ring 39 to move. The movement of the defoaming ring 39 caused by the rotation of the main shaft 35 achieves the cutting effect on the air bubbles in the ink stored in the fixed ring 31, preventing small air bubbles from agglomerating into large air bubbles, eliminating the hidden dangers of air bubbles in all directions, and preventing faults such as ink interruption, ink splatter, printing color difference, and incomplete lines caused by air bubbles. This ensures smooth ink flow, uniform and stable ink supply, improves inkjet printing accuracy and quality, and ensures the reliability of the equipment for long-term continuous operation.

[0028] When the device stops operating, the main shaft 35 rotates, causing the limit ring 38 to move forward. The limit ring 38 then causes the trigger plate 41 to move forward. When the trigger plate 41 moves into the working range of the second baffle 43, the trigger plate 41 causes the second baffle 43 to slide along the inclined surface on the guide post 42 towards the ink outlet along the inclined surface on the surface of the second baffle 43 until the second baffle 43 completely blocks the ink outlet on the surface of the first baffle 33. The rotation of the main shaft 35 then moves the second baffle 43, thus protecting the ink nozzle after the device stops operating. By blocking the ink outlet with the second baffle 43, external dust, impurities, and airflow can be isolated from contact with the nozzle, preventing ink from drying and forming a skin that could clog the printhead. At the same time, it prevents the first baffle 33 from being accidentally damaged, reducing contamination from ink dripping and leakage, keeping the ink outlet clean, and allowing for a smooth start-up. It can quickly and stably spray ink, reducing failure and debugging costs. When the device is running, the motor inside the fixed block 44 starts, and the output end of the motor drives the rocker arm 45 to rotate. The rotation of the rocker arm 45 drives the fixed block 46 to move in a circle around the rotation center of the rocker arm 45. The movement of the fixed block 46 drives the baffle plate 47 to move until the inner wall of the baffle plate 47 is in close contact with the surface of the fixed ring 31. The movement of the baffle plate 47 driven by the motor inside the fixed block 44 achieves the protection effect of the ejected ink droplets when the device is running. The extended baffle plate 47 can effectively block the interference of external airflow on the ink spraying process, prevent the ink droplets from being blown off course and scattered by the airflow, ensure that the flight trajectory of the ink droplets is straight and accurate, greatly improve the printing clarity and color registration accuracy, further ensure ink spraying stability, and make the equipment more reliable for long-term operation.

[0029] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the secondary ink cartridge 5 includes an ink cartridge 51, which is fixedly connected to the rear side of the fixing ring 31. A sealing rod 52 is fixedly connected to the inner wall of the fixing ring 31, and a baffle 3 54 is fixedly connected to the telescopic end of the sealing rod 52. The baffle 3 54 is arranged on the movement trajectory of the wind deflector 47.

[0030] Baffle 3 54 is slidably connected to the inner wall of fixed ring 31. Baffle 3 54 is in contact with the front side of ink cartridge 51. Limiting post 53 is fixedly connected to the surface of baffle 3 54. Limiting post 53 is slidably connected to the inner wall of fixed ring 31 by spring. The movement of baffle 3 54 on the inner wall of fixed ring 31 is driven by the rotation of baffle 47. This achieves the effect of preventing leakage of ink stored in ink cartridge 51 after the device stops running. When the machine stops, it can block the leakage channel formed by gravity and pressure difference in the ink path, prevent ink from overflowing and dripping. At the same time, it stabilizes the internal pressure of the ink path and reduces abnormal pressure leakage caused by air intake. It eliminates leakage problems such as ink dripping and leakage during shutdown from the source and avoids contamination of equipment and workpieces.

[0031] The secondary ink cartridge 5 also includes a fixing block 4 55, which is fixedly connected to the rear side of the baffle 3 54. A rocker arm 2 56 is rotatably connected to the surface of the fixing block 4 55, and a fixing block 5 57 is rotatably connected to the end of the rocker arm 2 56 away from the fixing block 4 55.

[0032] A turntable 58 is fixedly connected to the rear end of the fixed block 57. A stirring plate 59 is rotatably connected to the cylindrical surface of the turntable 58. A one-way spiral groove is opened on the inner wall of the ink box 51. The stirring plate 59 is spirally connected to the inner wall of the ink box 51. The movement of the baffle 3 54 drives the stirring plate 59 to move backward and rotate, thereby agitating the residual ink in the ink box 51. This effectively prevents pigment from settling and separating, ensures uniform and stable ink concentration and viscosity, avoids problems such as printing color difference, ink breakage, and nozzle clogging caused by uneven ink, ensures stable ink supply, and improves the inkjet quality and operational reliability of the device.

[0033] Working Principle: When the device stops running, the output end of the motor inside the fixed block 44 reverses, driving the rocker arm 45 to rotate. The rotation of the rocker arm 45 causes the fixed block 46 to move in a circular motion around the rotation center of the rocker arm 45. The fixed block 46 drives the baffle plate 47 to rotate. When the baffle plate 47 rotates to the working range of the baffle plate 54, the baffle plate 47 squeezes and drives the baffle plate 54 to move inward. The baffle plate 54 drives the limiting post 53 to move inward. At the same time, the baffle plate 54 drives the sealing rod 52 to move inward until the baffle plate 54 contacts the circumferential surface of the main shaft 35. The rotation of the baffle plate 47 drives the baffle plate 54 to move on the inner wall of the fixed ring 31, realizing the anti-leakage effect of the ink stored in the ink box 51 after the device stops running. When the machine stops, it can block the leakage channel formed by gravity and pressure difference in the ink path, preventing ink from overflowing and dripping. At the same time, it stabilizes the internal pressure of the ink path and reduces air intake. The abnormal pressure leakage caused by this prevents ink dripping and leakage during downtime, thus avoiding contamination of equipment and workpieces. As baffle 3 54 slides, it moves fixed block 4 55, which in turn rotates rocker arm 2 56. This rotation moves fixed block 57 backward, which in turn moves turntable 58. The turntable 58 then moves stirring plate 59. As stirring plate 59 moves backward, it rotates along the unidirectional spiral groove on the inner wall of ink cartridge 51. The movement of baffle 3 54, which drives stirring plate 59 backward and rotation, effectively stirs the residual ink in ink cartridge 51. This prevents pigment settling and stratification, ensuring uniform and stable ink concentration and viscosity. It avoids problems such as color difference, ink interruption, and nozzle clogging caused by uneven ink distribution, ensuring stable ink supply and improving the inkjet quality and operational reliability of the device.
