Description

Technical Field

[0001] This utility model relates to the field of book and periodical printing technology, specifically to an ink color adjustment mechanism for book and periodical printing. Background Technology

[0002] Book and periodical printing primarily produces books and periodicals. my country is the birthplace of printing technology. Pre-press processes include design (patterns and content), proofreading, and printing; post-press processes include folding and binding. Book and periodical printing utilizes special color inks, but the variety of commercially available ink colors is limited. Operators must mix the inks according to specific proportions. Ink color adjustment is affected by the proportions of various different colors. In existing technology: Authorization Publication Number CN Patent 213791445U discloses an ink mixing device for a printing press, comprising a mixing tank, a fixed frame, and a stirring device. The mixing tank is fixed to the fixed frame, and the stirring device is disposed inside the mixing tank. The bottom of the mixing tank has an outlet, and the periphery of the mixing tank has several inlets, each connected to a quantitative input device. The quantitative input device includes a measuring cylinder connected to the inlets. A compression piston is slidably connected inside the measuring cylinder, and a piston rod is connected above the compression piston. The piston rod has a guide cavity communicating with the measuring cylinder inside, and a sealing device for the guide cavity is located above the piston rod. The sealed cap of the chamber allows different colored inks to be pressed into the mixing tank according to the mixing ratio via a quantitative input device. The stirring device can stir the pressed-in inks of different colors to ensure thorough mixing and achieve the desired effect after mixing. However, the mixed inks for book and magazine printing have a certain degree of adhesion, resulting in a certain amount of ink residue remaining on the wall of the mixing tank after each color mixing process. This residual ink will affect the raw material ratio in the next ink mixing process, leading to inaccurate color mixing in subsequent inks. Therefore, we propose an ink color adjustment mechanism for book and magazine printing. Utility Model Content

[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] Please see Figure 1-5 This embodiment provides a technical solution: an ink adjustment mechanism for book and magazine printing, including an ink mixing shell 1. Four evenly distributed connecting pipes 3 are threaded through the upper end of the inner wall of the ink mixing shell 1. Each connecting pipe 3 has a feeding shell 4 at its upper end. The top wall of the ink mixing shell 1 is provided with six evenly distributed stirring rods 8 via a rotating shaft 7. The mechanism also includes a microcontroller 2, located outside the ink mixing shell 1. The input end of the microcontroller 2 is electrically connected to an external power supply. Each connecting pipe 3 has a feeding pump 5 connected in series at its upper end, and each connecting pipe 3 has a metering valve 6 connected in series at its lower end. The input end of each feeding pump 5 is connected to the microcontroller... The output of machine 2 is electrically connected, and the metering valve 6 is bidirectionally electrically connected to the microcontroller 2. A motor 11 is located on the upper side of the color mixing housing 1. The input of motor 11 is electrically connected to the output of the microcontroller 2. The output shaft of motor 11 is fixedly connected to the upper end of the rotating shaft 7. A discharge pipe 12 is provided through the bottom wall of the color mixing housing 1. A solenoid valve 13 is connected in series in the middle of the discharge pipe 12. The input of solenoid valve 13 is electrically connected to the output of the microcontroller 2. When using the ink color adjustment mechanism for book and magazine printing, the microcontroller 2 starts the feed pump 5, causing the primary color ink in the corresponding feed housing 4 to enter through the connecting pipe 3. The ink is fed into the color mixing shell 1. Simultaneously, the microcontroller 2 activates the metering valve 6 to adjust the flow rate of the primary color ink flowing through the connecting pipe 3, and transmits the adjustment result to the microcontroller 2 via an electrical signal. The microcontroller 2 obtains the corresponding total amount of primary color ink to be delivered based on the fluid flow rate of the metering valve 6 and the total time taken. When the corresponding total amount of primary color ink in the color mixing shell 1 is reached, the microcontroller 2 promptly shuts off the corresponding feed pump 5, thereby stopping the continued delivery of the corresponding primary color ink. Subsequently, the microcontroller 2 starts the motor 11, causing its output shaft to drive the rotating shaft 7 to rotate, and the rotating shaft 7 drives the stirring rod 8 to rotate. The device mixes and stirs the primary inks used for book and magazine printing in a certain proportion to obtain the required ink for book and magazine printing. During this process, the scraper 91 rotates synchronously with the rotating shaft 7 by rotating and engaging with the guide bar and the guide groove 10. The slide 973 slides adaptively along the annular slide groove 974. By adjusting the conveying ratio between the primary inks, the required ink for book and magazine printing is obtained. After the ink for book and magazine printing is prepared, the microcontroller 2 opens the solenoid valve 13 and collects it through the discharge pipe 12. The device also includes a cleaning mechanism 9.

[0024] Cleaning mechanism 9 includes a scraper 91, rectangular grooves 92, auxiliary scrapers 95, and a drive assembly 97. The scraper 91 is slidably connected to the interior of the color-mixing shell 1. Rectangular grooves 92 are provided at both the front and rear ends of the scraper 91. Auxiliary scrapers 95 are slidably connected inside the rectangular grooves 92. The auxiliary scrapers 95 are installed in conjunction with the stirring rod 8. The drive assembly 97 is provided between the scraper 91 and the color-mixing shell 1. The cleaning mechanism 9 also includes telescopic columns 93 and springs 94. The telescopic columns 93 and springs 94 are respectively disposed between the auxiliary scrapers 95 and adjacent rectangular grooves 92. The springs 94 are movably sleeved with the outer ends of adjacent telescopic columns 93. There are four telescopic columns 93 and four springs 94 between the auxiliary scrapers 95 and adjacent rectangular grooves 92. The cleaning mechanism 9 also includes guide ramps 96, which are respectively opened at the upper and lower edges of the auxiliary scraper 95. The drive assembly 97 includes an electro-hydraulic actuator 971, a cylinder 972, a slide block 973, and an annular groove 974. The annular groove 974 is opened on the upper side of the scraper 91, and the slide block 973 is slidably connected inside the annular groove 974. An electro-hydraulic actuator 971 is provided on the outer side of the color-mixing housing 1. The input end of the electro-hydraulic actuator 971 is electrically connected to the output end of the microcontroller 2. The telescopic end of the electro-hydraulic actuator 971 is provided with a cylinder 972 through a connecting rod. The lower end of the cylinder 972 passes through the top wall of the color-mixing housing 1 and is fixedly connected to the upper side of the slide block 973. A guide groove 10 is opened on the outer side of the rotating shaft 7. The upper side of the scraper 91 is guided by a guide groove 10. The strip is slidably connected to the guide groove 10. After each adjustment and preparation of the ink for book and magazine printing, the single-chip microcomputer 2 activates the electro-hydraulic push rod 971, causing its telescopic end to drive the cylinder 972 downward through the connecting rod. The cylinder 972 is slidably engaged with the annular slide groove 974 through the slide seat 973, thereby causing the scraper 91 to slide down along the gap between the rotating shaft 7 and the color mixing shell 1. During the downward movement of the scraper 91, its lower outer edge contacts the inner wall of the color mixing shell 1, thereby scraping off the residual ink for book and magazine printing on the inner wall of the color mixing shell 1. At the same time, as the scraper 91 moves downward, the scraper 91 slides vertically along the guide groove 10 through the guide strip, so that the scraper 91 and its internal auxiliary scraper 95 are always vertically aligned with the stirring rod 8. When the auxiliary scraper... When the auxiliary scraper 95 moves downward to contact the vertically adjacent stirring rod 8, the guide slope 96 on the lower side of the auxiliary scraper 95 first presses against the edge of the stirring rod 8. This pressing causes the auxiliary scraper 95 to scrape downwards along the stirring rod 8. Simultaneously, the auxiliary scraper 95 enters the corresponding rectangular groove 92 to avoid contact with the stirring rod 8. The telescopic end of the telescopic column 93 and the spring 94 retract, and the auxiliary scraper 95 scrapes vertically downwards against the surface of the stirring rod 8, thus removing residual ink for book printing. When the auxiliary scraper 95 is no longer in contact with the stirring rod 8, the compression and return force of the spring 94 causes the auxiliary scraper 95 to slide out of the rectangular groove 92 back to its initial state. The auxiliary scraper 95 then adaptively and tightly contacts the stirring rod 8 and the rotating shaft 7.This prevents residual printing ink from moving upwards along the gap formed by the auxiliary scraper 95, stirring rod 8, and rotating shaft 7 to the upper end of the color mixing shell 1 during the cleaning process. When the scraper 91 moves downwards along the inner wall of the color mixing shell 1 and presses against the bottom wall, the residual printing ink is squeezed out through the discharge pipe 12. The device, through a transmission element, causes the scraper part to move vertically downwards along the device wall, automatically cleaning out the residual printing ink and preventing it from interfering with the subsequent color mixing of printing inks, thus improving the accuracy of subsequent color mixing.

[0025] The working principle of the ink color adjustment mechanism for book and periodical printing provided by this utility model is as follows: When using the ink color adjustment mechanism for book and periodical printing, the microcontroller 2 starts the feed pump 5, which causes the primary color ink in the corresponding feed housing 4 to enter the color mixing housing 1 through the connecting pipe 3. At the same time, the microcontroller 2 starts the metering valve 6 to adjust the flow rate of the primary color ink flowing through the connecting pipe 3, and transmits the adjustment result to the microcontroller 2 in the form of an electrical signal. The microcontroller 2 obtains the total amount of primary color ink delivered according to the fluid flow rate of the metering valve 6 and the total time. When the corresponding primary color ink in the color mixing housing 1 reaches the corresponding total amount delivered, the microcontroller 2 promptly shuts off the corresponding feed pump 5, thereby stopping the continued delivery of the corresponding primary color ink. Subsequently, the microcontroller 2 starts the motor 11, causing its output shaft to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the stirring rod 8 to rotate, thereby mixing and stirring the primary color inks for book and magazine printing that are aggregated in a certain proportion within the device, thus obtaining the required ink for book and magazine printing. During this process, the scraper 91 rotates synchronously with the rotating shaft 7 through the rotational engagement of the guide strip and the guide groove 10. The slide 973 slides adaptively along the annular slide groove 974, adjusting the conveying ratio between the primary color inks to obtain the required ink for book and magazine printing. After the ink for book and magazine printing is prepared, the microcontroller 2 opens the solenoid valve 13, and the ink is collected through the discharge pipe 12. Each time the ink for book and magazine printing is prepared, the microcontroller 2 activates the electro-hydraulic push rod 971, causing its extension end to drive the cylinder 972 downward through the connecting rod. The cylinder 972 is connected to the annular slide groove 974 by the slide 973. The sliding engagement of the chute 974 allows the scraper 91 to slide down along the gap between the rotating shaft 7 and the color mixing shell 1. During the downward movement, the lower outer edge of the scraper 91 contacts the inner wall of the color mixing shell 1, thereby scraping away the residual ink for book printing on the inner wall of the color mixing shell 1. Simultaneously, as the scraper 91 moves downward, it slides vertically along the guide groove 10 via the guide strip, ensuring that the scraper 91 and its internal auxiliary scraper 95 remain vertically aligned with the stirring rod 8. When the auxiliary scraper 95 moves downward to contact the vertically adjacent stirring rod 8, the lower guide slope 96 of the auxiliary scraper 95 first presses against the edge of the stirring rod 8. This pressing causes the auxiliary scraper 95 to scrape downward along the stirring rod 8. The auxiliary scraper 95 moves vertically downwards along the surface of the stirring rod 8, thus removing residual printing ink from the stirring rod 8. When the auxiliary scraper 95 is not in contact with the stirring rod 8, the compression and return force of the spring 94 causes the auxiliary scraper 95 to slide out of the rectangular groove 92 back to its initial state. The auxiliary scraper 95 adaptively and tightly adheres to the stirring rod 8 and the rotating shaft 7, preventing residual printing ink from moving upwards along the gap between the auxiliary scraper 95, the stirring rod 8, and the rotating shaft 7 to the upper end of the color-mixing shell 1 during the cleaning process. When the scraper 91 moves downwards along the inner wall of the color-mixing shell 1 and presses against the bottom wall of the color-mixing shell 1...This process removes residual printing ink from the device through the discharge pipe 12, preventing ink residue and improving the accuracy of ink mixing for subsequent printing. The auxiliary scraper 95 and the adjacent rectangular groove 92 are each connected by four telescopic posts 93 and four springs 94.
