[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the positions of the four second limit holes are changed by rotating the rotating plate, and the four second limit holes interact with the limit rod, thereby driving the moving block to slide along the second slide groove to achieve precise motion trajectory adjustment. With the further rotation of the rotating plate, the four positioning frames move synchronously, driving the positioning plate to gradually approach the bottom end of the print head body, and through the elastic force of four tension springs, it is ensured that the positioning plate is close to the bottom end of the print head. The center rod ensures the synchronous fit of the four positioning plates, thereby enhancing the calibration accuracy. When the print head body remains vertical, the calibration mechanism does not interfere with the printing process. Once deflection occurs, the calibration mechanism immediately operates to apply a correction force through the positioning plate and the positioning frame to pull the print head back to a vertical state. This mechanism effectively ensures the stability of the print head and greatly improves the color printing accuracy and effect.

[0016] 2. In the present invention, after the driving motor is started, it drives the rotation of the rotating rod to activate the entire system. The movement of the rotating rod causes the crank to perform a circular motion around the center, exerting a force on the push rod. The push rod slides in the first limiting hole and transmits the force to the fan plate, causing it to start rotating. The push rod and the transmission rod work together to further control the clockwise and counterclockwise alternating rotation of the fan plate to avoid unidirectional movement and ensure smooth operation. The block effectively limits the movement of the push rod to ensure the stability of the system. The fan plate rotates stably under the guidance of the arc bar and the second limiting frame. Subsequently, the arc rack exerts a force on the driving gear, and the driving gear also rotates alternately. This movement is transmitted to the rotating plate. The alternating rotation of the rotating plate controls the closing and spreading of the positioning plate and the positioning frame. When closing, an adjustment force is applied to the print head body to ensure its accurate orientation. When spreading, the print head is allowed to move freely. This dynamic adjustment mechanism ensures the stability and accuracy of the print head during color printing and improves the overall printing efficiency.

[0017] 3. In the present invention, during the installation of the filter, firstly, the top and bottom ends thereof are connected to the ink delivery tube to ensure that the filter is tightly integrated with the ink delivery system. After the installation is completed, with the help of the elasticity of the spring, the system drives the movable frame to move, and the slider slides in the first slide groove to ensure that the movement trajectory of the movable frame is stable to avoid deviation or shaking. As the two movable frames gradually approach the filter, the filter can be firmly installed through the extrusion force applied by the arc plate to ensure that the connection between the filter and the ink delivery tube is tighter. At the same time, the first limit frame limits the movement range of the filter and the movable frame to ensure the precise installation of the system. After successful installation, the filter effectively filters the ink to prevent impurities from entering the print head system, ensure that the ink passes smoothly, and avoid clogging problems. This installation method improves printing efficiency and reduces the risk of downtime or maintenance due to ink clogging, thereby ensuring the stability of the printing process and high-quality output.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Reference Figure 1 - Figure 6 As shown: A color printing device capable of improving color printing effect, comprising a color printing machine 1, a placing plate 2 is installed inside the color printing machine 1, a print head body 3 is installed above the placing plate 2, a driving mechanism 6 is installed below the print head body 3, a calibration mechanism 7 is installed on one side of the driving mechanism 6, an ink delivery tube 4 is installed inside the print head body 3, and a filter 5 is installed in the middle of the ink delivery tube 4; The calibration mechanism 7 includes a fixed plate 71 and a rotating plate 72. The surface of the fixed plate 71 is provided with four second slide grooves 74. A moving block 75 is slidably connected inside the second slide groove 74. A limiting rod 751 is fixedly connected to the top of one end of the moving block 75. The surface of the rotating plate 72 is provided with four second limiting holes 721. The top of the limiting rod 751 passes through the second limiting hole 721, and the limiting rod 751 is slidably connected to the second limiting hole 721. A positioning frame 752 is fixedly connected to the top of the second limiting hole 721. A center rod 761 is rotatably connected to the bottom of one end of the moving block 75. A positioning plate 76 is fixedly connected to the outer surface of the center rod 761. Four tension springs 77 are arranged below the fixed plate 71. Two fixing rods 78 are symmetrically fixedly connected to the inner wall of the positioning plate 76. The two ends of the tension spring 77 are respectively hung on the outer surface of a fixing rod 78 on the inner side of the two positioning plates 76. A toothed ring 73 is fixedly connected to the outer surface of the rotating plate 72. The bottom width of the positioning frame 752 is greater than the width of the second limiting hole 721. A filter 51 is installed inside the print head body 3 , the top of the filter 51 is fixedly connected to the ink delivery tube 4 , and the bottom of the filter 51 passes through the rotating plate 72 and the fixed plate 71 in sequence.

[0022] In this embodiment, during the long-term operation of the color printer 1, the movement control of the print head body 3 is very important. In particular, after long-term use, the print head may deviate or tilt, affecting the color printing accuracy. In order to effectively solve this problem, the color printer 1 is designed with a set of calibration mechanisms 7, which can automatically adjust the position of the print head when it deviates, ensuring that it remains in an ideal vertical state, thereby ensuring the printing effect.

[0023] In this calibration mechanism, the rotation of the rotating plate 72 plays a key role. When the rotating plate 72 starts to rotate, the positions of the four second limiting holes 721 on its surface will change. These limiting holes will interact with the limiting rod 751 during the rotation process. The force applied by the second limiting holes 721 will be transmitted to the limiting rod 751, and the limiting rod 751 will then transmit the force to the moving block 75, so that the moving block 75 slides along the second slide groove 74. During the sliding process, the moving block 75 is limited by the second slide groove 74 to ensure that its movement trajectory is accurate and does not deviate from the designed path. This controlled movement enables the moving block 75 to drive the entire system to further adjust the orientation of the print head body 3.

[0024] As the rotating plate 72 rotates further, the four second limiting holes 721 thereon will synchronously apply forces to the four positioning frames 752, and the four positioning frames 752 will start to move accordingly. In this process, the synchronous movement of the four positioning frames 752 causes the associated moving blocks 75 to move synchronously, and finally the moving blocks 75 drive the positioning plate 76 to follow the movement. The movement of the positioning plate 76 will gradually approach the bottom end of the print head body 3, and under the coordinated action of the limiting rod 751, the positioning frame 752 also moves with the positioning plate 76, so that the entire system is in a coordinated motion state, ensuring the stability of the print head.

[0025] When the four positioning brackets 752 are close to the toothed ring 73, the system will use the elastic force of the four tension springs 77 to make the positioning plate 76 further close to the bottom end of the print head body 3. Here, the synergistic effect of the center rod 761 is also very important, which ensures the synchronous fit of the four positioning plates 76, thereby enhancing the calibration accuracy. Although the positioning plate 76 has a certain rotation ability in the system, the force it exerts will gradually promote the orientation correction of the print head body 3, and finally ensure that the print head remains in a completely vertical state.

[0026] When the print head body 3 remains vertical and not skewed, the calibration mechanism 7 will not interfere with it, ensuring the smooth printing process. However, when the print head body 3 is skewed, the calibration mechanism 7 will immediately start to operate. Through the coordinated driving action of the four positioning plates 76 and the four positioning frames 752, the calibration mechanism 7 can apply appropriate correction force to the print head body 3 to pull it back to a vertical state. This mechanism not only ensures the stability of the print head body 3, but also greatly improves the color.

[0027] Embodiment 2: Figure 3 , Figure 6 and Figure 7As shown, the driving mechanism 6 includes a fixed frame 61, the top of the fixed frame 61 is fixedly connected to the print head body 3, and the bottom of the fixed frame 61 is fixedly connected to the fixed plate 71, the top of the fixed frame 61 is rotatably connected to the fan-shaped plate 62, the outer side of the fan-shaped plate 62 is fixedly connected to the arc-shaped bar 622, the outer surface of the arc-shaped bar 622 is fixedly connected to the arc-shaped rack 64, one side of the arc-shaped rack 64 is meshedly connected to the driving gear 63, the driving gear 63 is meshedly connected to the gear ring 73, and the bottom of the driving gear 63 is rotatably connected to the fixed frame 61. The arc-shaped bar 622 is slidably connected to the second limit frame 67 on both sides, the bottom of the second limit frame 67 is fixedly connected to the fixed frame 61, the top of the fixed frame 61 is rotatably connected to the rotating rod 68, the top of the rotating rod 68 is fixedly connected to the crank 65, and the top of the crank 65 is rotatably connected to the transmission rod 66. A first limiting hole 621 is provided in the middle of the sector plate 62, a push rod 661 is slidably connected to the inside of the first limiting hole 621, the top of the push rod 661 is fixedly connected to the transmission rod 66, and a stopper 662 is fixedly connected to the bottom of the push rod 661, and the width of the stopper 662 is greater than the width of the first limiting hole 621. A driving motor 8 is installed at the bottom of the fixing frame 61, and the output end of the driving motor 8 is fixedly connected to the rotating rod 68.

[0028] In this embodiment, when the driving motor 8 starts to run, it starts the action of the entire system by driving the rotation of the rotating rod 68. The rotation of the rotating rod 68 causes the crank 65 to make a circular motion around the center of the rotating rod 68. In this process, the movement of the crank 65 will exert a force on the push rod 661, and the push rod 661 will not only slide in the first limiting hole 621, but also transmit the force to the fan plate 62. As the fan plate 62 is subjected to the force of the push rod 661, it also starts to move and rotate.

[0029] When the crank 65 continues to move in a circular motion, the push rod 661 cooperates with the transmission rod 66 to further control the movement of the sector plate 62. Under the guidance of the first limiting hole 621, the sector plate 62 rotates alternately clockwise and counterclockwise. This alternating rotation helps to avoid unidirectional movement and ensure the smooth operation of the sector plate 62. At this time, the existence of the stopper 662 is very important, which effectively limits the range of motion of the push rod 661, prevents the push rod 661 from being disengaged from the first limiting hole 621, and ensures the continuity and stability of the entire system.

[0030] During the movement of the sector plate 62, the arcuate bar 622 is limited by the second limit frame 67, so that it rotates within a stable trajectory. As the sector plate 62 rotates alternately, the arcuate rack 64 begins to exert force on the drive gear 63, so that the drive gear 63 also rotates alternately clockwise and counterclockwise in the same way. This movement is further transmitted to the rotating plate 72, so that the rotation of the rotating plate 72 is consistent with the movement of the sector plate 62 and the drive gear 63.

[0031] This alternating rotation of the rotating plate 72 ultimately controls the closing and spreading movement of the positioning plate 76 and the positioning frame 752. When the positioning plate 76 and the positioning frame 752 are closed, they apply a force to the print head body 3 to ensure that the orientation of the print head is properly adjusted and corrected. When the positioning plate 76 and the positioning frame 752 are spread apart, they release the force applied to the print head, allowing the print head to move freely when needed. This dynamic adjustment mechanism ensures the stability and accuracy of the print head body 3 throughout the color printing process.

[0032] Embodiment 3: According to Figure 8 and Fig. 9 As shown, the filter element 5 includes two mounting plates 52, the bottom of the mounting plate 52 is fixedly connected to the print head body 3, the surface of the mounting plate 52 is provided with a first slide groove 58, the inner side of the first slide groove 58 is slidably connected with a slider 59, the top of the slider 59 is fixedly connected with a moving frame 53, and the top of the moving frame 53 is fixedly connected with an arc plate 54. A filter 51 is arranged between the two arc plates 54, the top and bottom of the filter 51 are fixedly connected to the ink delivery tube 4, and a plurality of first limit frames 55 are fixedly connected to the top and bottom of the arc plate 54. A spring 56 is arranged inside the mounting plate 52, and limit blocks 57 are arranged inside both ends of the spring 56, one of the limit blocks 57 is fixedly connected to the mounting plate 52, and the other limit block 57 is fixedly connected to the moving frame 53.

[0033] In this embodiment, during the installation of the filter 51, the top and bottom ends of the filter 51 are first connected to the ink delivery tube 4 respectively, ensuring that the filter 51 is in the correct position and is tightly combined with the ink delivery system. After the installation is completed, the system can drive the mobile frame 53 to move by utilizing the elasticity of the spring 56. During this process, the slider 59 at the bottom of the mobile frame 53 will slide in the first slide groove 58. The design of the slide groove can ensure that the movement trajectory of the mobile frame 53 is stable and controlled, and prevent the mobile frame 53 from deflecting or shaking during the movement.

[0034] As the two moving frames 53 gradually approach the filter 51, they apply a squeezing force to the filter 51 through the two curved plates 54. The application of this squeezing force not only helps to firmly install the filter 51 at the predetermined position, but also ensures a tighter connection between the filter 51 and the ink delivery tube 4. At the same time, the first limiting frame 55 plays a limiting role, ensuring that the movement range of the filter 51 and the moving frame 53 does not exceed the designed allowable range, thereby ensuring the accurate installation of the entire system.

[0035] When the installation is successfully completed, the filter 51 will be able to effectively filter the ink and prevent impurities from entering the print head system. Through this installation method, the filter 51 can operate stably to ensure that the ink passes smoothly during printing without causing clogging of the printing system due to impurities. This not only improves printing efficiency, but also greatly reduces the risk of downtime or maintenance caused by ink clogging, ultimately ensuring stable printing and high-quality output.

[0036] The use method and working principle of the device: When the color printer 1 is running, the movement of the print head body 3 is controlled. In order to prevent the print head body 3 from being deviated or skewed during long-term use, the rotation of the rotating plate 72 can change the position of the second limiting hole 721. In this process, the second limiting hole 721 applies a force to the limiting rod 751, and the limiting rod 751 transmits the force to the moving block 75, causing the moving block 75 to slide in the second slide groove 74 and be restricted by the second slide groove 74.

[0037] When the driving motor 8 is running, it drives the rotating rod 68 to rotate, so that the crank 65 performs a circular motion around the rotating rod 68. In this process, the crank 65 controls the push rod 661 to exert a force, and the push rod 661 not only slides in the first limiting hole 621, but also exerts a force on the fan-shaped plate 62. As the fan-shaped plate 62 starts to move and rotate, the crank 65 continues to perform a circular motion, and the transmission rod 66 cooperates with the push rod 661 to control the rotation of the fan-shaped plate 62 through the first limiting hole 621, so that it rotates alternately clockwise and counterclockwise. The existence of the stopper 662 limits the push rod 661 to prevent it from being separated from the first limiting hole 621.

[0038] When the fan plate 62 moves, the arc bar 622 keeps rotating stably under the restriction of the second limit frame 67, and the arc rack 64 applies force to the driving gear 63, so that the driving gear 63 rotates alternately clockwise and counterclockwise. When the force is transmitted to the rotating plate 72, the rotating plate 72 also rotates in the same way.

[0039] As the rotating plate 72 continues to rotate, the four second limiting holes 721 on the surface of the rotating plate 72 simultaneously exert forces on the four positioning frames 752, pushing the four moving blocks 75 to move synchronously, and driving the positioning plates 76 to move together. Finally, the four positioning plates 76 gradually approach the bottom end of the print head body 3. In this process, the limiting rod 751 also drives the positioning frames 752 to move together.

[0040] When the four positioning frames 752 approach the toothed ring 73, under the action of the four tension springs 77, the four positioning plates 76, through the coordinated action of the center rod 761, are close to the bottom end of the print head body 3. Although the positioning plates 76 can rotate, the force they exert causes the print head body 3 to gradually adjust to a vertical state. As long as the print head body 3 remains vertical, the operation of the calibration mechanism 7 will not interfere with it. If the print head body 3 is skewed, the driving force of the four positioning plates 76 and the four positioning frames 752 can correct its position, ensuring that the print head body 3 always remains vertical, thereby ensuring the color printing effect.

[0041] When installing the filter 51, its top and bottom are connected to the ink delivery tube 4 respectively. After installation, the elasticity of the spring 56 pushes the movable frame 53, so that the slider 59 at the bottom of the movable frame 53 slides in the first slide groove 58, ensuring that the movable frame 53 remains stable when moving. As the two movable frames 53 approach the filter 51, the installation of the filter 51 is completed through the squeezing of the two arc plates 54 and the restriction of the first limit frame 55, thereby ensuring its effective filtration of ink and avoiding clogging during printing.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
