Description

Technical Field

[0001] This utility model relates to the technical field of multi-unit ink supply mechanisms, specifically a multi-unit ink supply mechanism for book and periodical printing presses. Background Technology

[0002] In the book and magazine printing industry, multi-unit ink supply systems have become a key supporting equipment for modern book and magazine printing presses because they can meet the continuous and stable ink supply needs of printing presses. The uniformity of ink supply directly determines the color consistency and printing quality of printed materials. Therefore, it is necessary to design multi-unit ink supply systems for book and magazine printing presses.

[0003] Patent document CN216659311U discloses a multi-unit ink supply mechanism for a book and magazine printing press, including an ink tank. The top of the ink tank has an ink inlet, and the side wall of the ink tank has an ink outlet. An ink outlet pipe is installed inside the ink outlet, and a water pump for extracting ink is installed on the ink outlet pipe. An ink-spreading shaft is installed inside the ink tank, and ink-spreading blades are installed on the side wall of the ink-spreading shaft. A drive motor for driving the ink-spreading shaft to rotate is installed on the ink tank. This application has the effect of improving the uniformity of ink application.

[0004] However, this device lacks the ability to scrape down and mix the ink adhering to the inner wall of the tank during the rotation and stirring process. The adhering ink will gradually solidify and form sediment over time, which not only wastes ink but may also block key channels such as the feed pipe and discharge pipe, affecting the normal operation of the ink supply mechanism, reducing stirring efficiency and ink usage effect. Furthermore, this device lacks the means to simultaneously transfer ink to different printing devices, and can only supply ink to one printing machine, which affects ink efficiency and indirectly affects printing efficiency. Utility Model Content

[0005] The main purpose of this invention is to provide a multi-unit ink supply mechanism for book and magazine printing presses. This mechanism effectively solves the problem in the prior art where, during the rotation and stirring process, the ink adhering to the inner wall of the tank is scraped off and stirred evenly. However, the long-term accumulation of the adhering ink gradually solidifies into sediment, which not only wastes ink but may also clog key channels such as the feed pipe and discharge pipe, affecting the normal operation of the ink supply mechanism, reducing stirring efficiency and ink usage. Furthermore, this device lacks a mechanism to simultaneously transfer ink to different printing units, allowing it to be used by only one printing machine, which affects ink efficiency and indirectly affects printing efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-unit ink supply mechanism for a book and magazine printing press includes a tank body with a lid mounted on the top. A stirring mechanism is rotatably connected to the bottom of the lid. A discharge nozzle extends through the left side of the bottom of the tank body. A multi-unit conveying mechanism extends through the interior of the discharge nozzle. The stirring mechanism includes a stirring rod rotatably connected to the bottom of the lid. A stirring disc is fixedly connected to both the upper and lower ends of the stirring rod. Scrapers are fixedly connected to both sides of the stirring disc. An inclined stirring fan is fixedly connected to the middle of the stirring rod. The multi-unit conveying mechanism includes a discharge pipe extending through the interior of the discharge nozzle. A pneumatic diaphragm pump extends through the end of the discharge pipe. A conveying pipe extends through the top of the pneumatic diaphragm pump. Three branch pipes extend through the bottom of the conveying pipe.

[0008] Preferably, eight stirring blades are fixedly connected around the stirring plate, with one side of two opposing stirring blades fixedly connected to the top of the scraper. The stirring plate has eight material passage windows inside. The eight stirring blades work together with the stirring plate to rotate at high speed, so as to fully stir the ink in the tank, avoid pigment sedimentation, and ensure ink uniformity. The scraper can simultaneously scrape off the ink adhering to the inner wall of the tank, reducing waste and preventing blockage.

[0009] Preferably, the top surface of the stirring rod is rotatably connected to a rotating connector, and the top end of the rotating connector is fixedly connected to a drive motor. The rotating connector forms a power transmission bridge between the stirring rod and the drive motor, ensuring stable power transmission. The drive motor provides continuous rotational power to the stirring rod, and the speed can be adjusted to meet different stirring needs, ultimately achieving efficient and uniform stirring and ensuring ink quality.

[0010] Preferably, a sealing sleeve is fitted inside the nozzle, and the sealing sleeve is fitted outside the top end of the discharge tube. The sealing sleeve is double-fitted inside the nozzle and outside the top end of the discharge tube to form a double sealing structure, which effectively prevents ink leakage, reduces frictional wear at the connection between the nozzle and the discharge tube, extends the service life of the components, and ensures the sealing and stability of the ink supply channel, ensuring a smooth ink supply process.

[0011] Preferably, a discharge valve is fixedly connected to the outside of the discharge pipe, and a flow sensor is installed on the outside of the conveying pipe. Straps are fixedly connected to both sides of the flow sensor and are sleeved on the outside of the conveying pipe. The discharge valve can accurately control the start and stop of the discharge and the flow rate to prevent ink leakage and ensure the controllability of ink supply. The flow sensor monitors the ink flow in the conveying pipe in real time, providing data support for ink supply adjustment. The straps securely fix the flow sensor to prevent it from shifting due to vibration, ensuring accurate flow measurement and stable operation of the overall ink supply system.

[0012] Preferably, a dispensing valve is fixedly connected to the top of each of the three connecting pipes, and an inlet is provided on the left side of the top surface of the can lid. A sealing cap is installed on the outside of the inlet. The dispensing valve can precisely control the start and stop of the material conveying and the flow rate of the three connecting pipes, so as to realize the ink dispensing on demand and adapt to the ink supply needs of different printing presses.

[0013] Preferably, a liquid level sensor is fixedly connected to the side of the tank, and a cleaning valve is connected to the bottom of the tank. The liquid level sensor monitors the ink level in the tank in real time, which facilitates timely replenishment and avoids ink supply interruption. The cleaning valve can discharge residual ink and impurities during maintenance, which facilitates tank cleaning and ensures the purity of subsequent ink supply.

[0014] Preferably, a base is fixedly connected to the bottom surface of the tank, and a PLC control box is fixedly connected to the top right side of the base. The base provides stable support for the tank, ensuring the overall stability of the equipment and preventing shaking during operation. The PLC control box can centrally control various components of the ink supply mechanism, improving ink supply efficiency and stability.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model, through the setting of a stirring mechanism, allows for the stirring of ink inside the tank when it needs to be used. A stirring rod is installed inside the tank, and the stirring rod is connected to a drive motor via a rotating connector at its top. The drive motor then provides power to rotate the stirring rod inside the tank. A stirring plate with eight stirring blades is installed at both the upper and lower ends of the stirring rod. Scrapers are also installed on the two opposite stirring blades. The scrapers are in contact with the inner wall of the tank and scrape against the inner wall as the stirring plate rotates. Since three inclined stirring fans are also installed in the middle of the stirring rod, they work together with the stirring plate to stir the upper, middle and lower parts of the tank. This achieves simultaneous stirring of the upper, middle and lower parts while preventing residual ink from adhering to the inner wall of the tank. This avoids long-term accumulation of ink, which not only wastes ink but may also clog the pipes, affect the normal operation of the ink supply mechanism, and reduce stirring efficiency and ink usage effect.

[0017] 2. This utility model, through the setting of a multi-connection feeding mechanism, installs a discharge nozzle on one side of the bottom of the tank when ink needs to be supplied to different printing machines. The ink enters the discharge pipe through the discharge nozzle, and then enters the pneumatic diaphragm pump through the discharge valve. The pneumatic diaphragm pump transports the ink through the feeding pipe to three branch pipes, and then the branch pipes transmit the ink to different printing machines for use. Since a distribution valve is also set on the outside of the branch pipe, the use of the branch pipe can be freely controlled, realizing the simultaneous supply of ink to multiple printing machines, avoiding the situation where only one printing machine can be used, which would affect the efficiency of ink and indirectly affect the printing efficiency.

However, a stirring plate 302 with eight stirring blades 6 is installed at both the upper and lower ends of the stirring rod 301. A scraper 303 is also installed on the two opposite stirring blades 6. The scraper 303 is in contact with the inner wall of the tank 1 and scrapes the inner wall as the stirring plate 302 rotates. Since three inclined stirring fans 304 are also installed in the middle of the stirring rod 301, they work together with the stirring plate 302 to stir the ink in the upper, middle and lower parts of the tank 1.

[0027] Please see Figure 3 The multi-connector conveying mechanism 5 includes a discharge pipe 501 that runs through the inside of the discharge nozzle 4.

A rotating connector 8 is rotatably connected to the top surface of the stirring rod 301. A drive motor 9 is fixedly connected to the top of the rotating connector 8. The rotating connector 8 forms a power transmission bridge between the stirring rod 301 and the drive motor 9, ensuring stable power transmission. The drive motor 9 provides continuous rotational power to the stirring rod 301. The speed can be adjusted to meet different stirring needs, ultimately achieving high efficiency. Uniform stirring ensures ink quality. A sealing sleeve 10 is fitted inside the nozzle 4, and this sleeve is fitted onto the outside of the top end of the discharge pipe 501. The double-sealing sleeve 10, fitted inside the nozzle 4 and outside the top end of the discharge pipe 501, forms a double-seal structure, effectively preventing ink leakage, reducing frictional wear at the connection between the nozzle 4 and the discharge pipe 501, extending component lifespan, and ensuring the sealing and stability of the ink supply channel, guaranteeing smooth ink supply. A discharge valve 11 is fixedly connected to the outside of the discharge pipe 501, and a flow sensor 12 is installed on the outside of the conveying pipe 503. Straps 13 are fixedly connected to both sides of the flow sensor 12, fitting onto the outside of the conveying pipe 503.

The flow sensor 12 monitors the ink flow rate in the feed pipe 503 in real time, providing data support for ink supply adjustment. The strap 13 securely fixes the flow sensor 12 to prevent it from shifting due to vibration, ensuring accurate flow measurement and stable operation of the overall ink supply system. A distributing valve 14 is fixedly connected to the top of the three branch pipes 504. An inlet is located on the left side of the top surface of the tank cover 2, and a sealing cap 15 is installed outside the inlet. The distributing valve 14 can precisely control the start / stop and flow rate of the three branch pipes 504, enabling ink to be distributed as needed to adapt to the ink supply requirements of different printing presses. A liquid level sensor is fixedly connected to the side of the tank body 1. The bottom of the tank 1 is connected to a cleaning valve 17. The liquid level sensor 16 monitors the ink level in the tank in real time, which facilitates timely replenishment and avoids ink supply interruption.

The bottom surface of the tank 1 is fixedly connected to a base 18, and the top right side of the base 18 is fixedly connected to a PLC control box 19. The base 18 provides stable support for the tank 1, ensuring the overall stability of the equipment and preventing shaking during operation. The PLC control box 19 can centrally control various components of the ink supply mechanism to improve ink supply efficiency and stability.

[0030] Working principle: With the setting of the stirring mechanism 3, when the ink inside the tank 1 needs to be stirred, a stirring rod 301 is installed inside the tank 1. The stirring rod 301 is connected to the drive motor 9 by the rotating connector 8 at its top end, and then the drive motor 9 provides power to rotate inside the tank 1. However, a stirring plate 302 with eight stirring blades 6 is installed at both the upper and lower ends of the stirring rod 301. A scraper 303 is also installed on the two opposite stirring blades 6. The scraper 303 is in contact with the inner wall of the tank 1 and scrapes the inner wall as the stirring plate 302 rotates. Since three inclined stirring fans 304 are also installed in the middle of the stirring rod 301, they work together with the stirring plate 302 to stir the upper, middle and lower parts of the tank 1.

[0031] With the setting of the split conveying mechanism, when ink needs to be delivered to different printing machines, a discharge nozzle 4 is installed on one side of the bottom of the tank 1. The ink enters the discharge pipe 501 through the discharge nozzle 4, and then enters the pneumatic diaphragm pump 502 through the discharge valve 11. The pneumatic diaphragm pump 502 transports the ink through the conveying pipe 503 to the three split pipes 504. Then, the split pipes 504 deliver the ink to the inside of different printing machines for use. Since a dispensing valve 14 is also set on the outside of the split pipe 504, the use of the split pipe 504 can be freely controlled. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
