Description

Technical Field

[0001] This invention relates to the field of automatic ink supply equipment technology, and in particular to an automatic ink supply system for a color printing press. Background Technology

[0002] Color printing presses achieve color printing by using a color separation process to decompose an image into four colors of ink: cyan, magenta, yellow, and black, which are then superimposed and reproduced. A color printing press is generally equipped with four ink tanks, each storing cyan, magenta, yellow, and black ink respectively. In existing technology, ink supply to the ink tanks is primarily manual. Specifically, operators dispense an appropriate amount of ink from the ink container in the mixing room into a storage container, and then manually transfer it to the corresponding ink tank, thus completing the ink supply for the color printing press. This ink supply method suffers from low ink supply efficiency, affecting the overall production efficiency of color printing. Therefore, the inventor provides an automatic ink supply system for a color printing press. Summary of the Invention

[0003] To address the problem of low ink supply efficiency in existing ink supply methods, which affects the production efficiency of color printing, this invention provides an automatic ink supply system for a color printing machine.

[0004] The automatic ink supply system for a color printing press provided by this invention is achieved through the following technical solution: An automatic ink supply system for a color printing press includes an ink dispensing subsystem located in a constant temperature and humidity environment, an ink supply pipe connected to the ink dispensing subsystem, and an ink dispensing assembly fixedly connected to the ink trough of the color printing press. One end of the ink supply pipe is connected to the ink supply pipe, and the other end is connected to the ink dispensing assembly. The ink dispensing assembly is connected to an ink quality control component. One end of the ink quality control component is connected to the ink supply pipe, and the other end is connected to the ink dispensing assembly.

[0005] This invention enables automated ink supply to color printing presses, achieving high ink supply efficiency and effectively improving color printing production efficiency.

[0006] Preferably, the ink dispensing assembly includes a bracket fixedly connected to the ink tank of the color printing machine, a main ink dispensing pipe fixedly connected to the bracket and communicating with the ink quality control component, and a plurality of branch ink dispensing pipes fixedly connected to the periphery of the main ink dispensing pipe, with the spacing between adjacent branch ink dispensing pipes being the same; the ink outlet of the branch ink dispensing pipes is vertically oriented towards the ink tank of the color printing machine.

[0007] By adopting the above technical solution, it can be ensured that the ink flows evenly into the ink trough of the color printing machine.

[0008] Preferably, the bracket is equipped with an ultrasonic liquid level sensor.

[0009] By adopting the above technical solution, when the ultrasonic liquid level sensor detects that the ink level in the ink tank is too low (the alarm is set to sound when the ink level is below 1 / 4 of the ink tank level), the ultrasonic liquid level sensor will sound an alarm, and the automatic ink supply system will automatically dispense ink into the ink tank to adjust the ink level, thereby ensuring continuous printing production.

[0010] Preferably, the ink quality control component includes an end ink supply tube and an ink supply hose. One end of the end ink supply tube is connected to the ink supply pipe and the other end is connected to the ink supply hose. The ink supply hose is connected to the end ink supply tube and the other end is fixedly connected to the side wall of the ink outlet main pipe. The end ink supply tube is equipped with a control valve.

[0011] Preferably, the end ink supply pipe is equipped with a pipe temperature sensor located downstream of the control valve; the end ink supply pipe is equipped with a flow meter located downstream of the control valve.

[0012] More preferably, the end ink supply tube is provided with a pipe heater located upstream of the control valve.

[0013] By adopting the above technical solution, thermal compensation can be performed on the transmission ink, and the ink output temperature can be precisely controlled.

[0014] Preferably, the ink dispensing subsystem includes a sealing cover that is sealed and slidably connected to the ink tank, a hydraulic operating component for driving the upper and lower sealing to slide, a vacuuming component connected to the sealing cover, and an ink stirring component fixedly connected to the sealing cover. The upper surface of the sealing cover is provided with an ink outlet pipe that is connected to the ink supply pipe.

[0015] When the ink dispensing subsystem is running, a gap is left between the sealing cap and the ink surface in the ink tank. The vacuuming component performs vacuuming. Then, the hydraulic operating component drives the sealing cap to press down, so that the lower surface of the sealing cap contacts the ink surface in the ink tank. The pressure continues to press down, causing the ink to fill the hidden groove of the stirring paddle. The ink stirring component starts stirring and stirs for 3-5 minutes. The hydraulic operating component drives the sealing cap to rise, leaving a 1cm gap between the sealing cap and the ink surface in the ink tank. The vacuuming component then performs vacuuming again to defoam the ink in the ink tank. The hydraulic operating component drives the sealing cap to press down, causing the ink to fill the hidden groove of the stirring paddle. The pressure continues to press down, forcing the ink in the ink tank into the ink outlet pipe and transmitting it to the ink supply pipe.

[0016] Preferably, the sealing cap is integrally formed with a stirring paddle hiding groove; the ink stirring assembly includes a drive motor fixedly connected to the upper surface of the sealing cap, a stirring shaft coaxially fixedly connected to the output shaft of the drive motor, and a stirring paddle fixedly connected to the stirring shaft and located inside the stirring paddle hiding groove. One end of the stirring shaft is sealed and rotatably passes through the sealing cap and is coaxially fixedly connected to the output shaft of the drive motor. The stirring paddle is disposed on the periphery of the other end of the stirring shaft.

[0017] Preferably, the hydraulic operating assembly comprises two parts: a hydraulic cylinder located around the ink barrel, a support frame, and a sealing cap connecting rod. The piston rod of the hydraulic cylinder is fixedly connected to the support frame; one end of the sealing cap connecting rod is fixedly connected to the support frame, and the other end of the sealing cap connecting rod is fixedly connected to the upper surface of the sealing cap.

[0018] Preferably, the upper surface of the sealing cover is provided with a vacuum connector that is connected to the vacuum assembly; the vacuum assembly includes a vacuum pipe, a buffer tank, and a vacuum pump, one end of the vacuum pipe is connected to the vacuum connector and the other end is connected to the buffer tank; the buffer tank is connected to the vacuum pump.

[0019] In summary, the present invention has the following advantages: the automatic ink supply system for color printing machines provided by the present invention can realize automated ink supply for color printing machines, with high ink supply efficiency, ensuring that ink flows evenly into the ink trough of the color printing machine, enabling continuous printing production, and effectively improving the production efficiency of color printing.

The four ink dispensing subsystems 1 automatically output cyan ink, magenta ink, yellow ink, and black ink, respectively. The four ink dispensing subsystems 1 are located in a constant temperature and humidity environment to ensure the quality of the stored ink and the output ink. The four ink supply pipes 2 are respectively coated as cyan ink supply pipes, magenta ink supply pipes, yellow ink supply pipes, and black ink supply pipes. The cyan ink supply pipe is connected to the ink dispensing subsystem 1 that automatically outputs cyan ink. The magenta ink supply pipe is connected to the ink dispensing subsystem 1 that automatically outputs magenta ink. The yellow ink supply pipe is connected to the ink dispensing subsystem 1 that automatically outputs yellow ink.

One end of a single ink supply pipe 2 is fixedly connected to the ink dispensing subsystem 1 of the corresponding color via a flange, and the other end of the ink supply pipe 2 is fixedly connected to the ink dispensing assembly 3 of the corresponding color via a flange. For example, the ink dispensing assembly 3 is fixedly connected to the cyan ink tank of a color printing press, and the ink dispensing assembly 3 is fixedly connected to the cyan ink supply pipe, which in turn is connected to the ink dispensing subsystem 1 that automatically outputs cyan ink.

[0027] refer to Figure 1 and Figure 2 The ink dispensing assembly 3 includes a bracket 31 fixedly connected to the ink tank of the color printing press, an ink dispensing main pipe 32 fixedly connected to the bracket 31 and fixedly connected to the ink quality control assembly 4, and several ink dispensing branch pipes 33 fixedly connected to the periphery of the ink dispensing main pipe 32. The ink dispensing main pipe 32 is located directly above the ink tank, and the spacing between adjacent ink dispensing branch pipes 33 is the same. The ink outlets of the ink dispensing branch pipes 33 are vertically oriented towards the ink tank of the color printing press, which can ensure that the ink flows evenly into the ink tank of the color printing press.

[0028] refer to Figure 1 and Figure 2 To accurately monitor the ink level in the ink tank, an ultrasonic level sensor 34 is fixedly connected to the bracket 31 of the ink dispensing assembly 3. When the ultrasonic level sensor 34 detects that the ink level in the ink tank is too low (an alarm is triggered if the level is below 1 / 4 of the ink tank level), the ultrasonic level sensor 34 emits an alarm sound, and the automatic ink supply system automatically dispenses ink into the ink tank to adjust the ink level.

The ink outlet end of the ink supply hose 42 is threadedly connected to the side wall of the main ink dispensing pipe 32. A control valve 411 is installed on the terminal ink supply pipe 41. The control valve 411 is preferably a solenoid valve, which enables electrically controlled ink flow, eliminating the need to manually rotate the valve and improving ink supply efficiency.

[0030] refer to Figure 1 and Figure 3 The ink dispensing subsystem 1 includes a sealing cover 11 that is sealed and slidably connected to the ink tank, a hydraulic operating component 12 for driving the upper and lower sealing to slide, a vacuuming component 13 connected to the sealing cover 11, and an ink stirring component 14 fixedly connected to the sealing cover 11. The upper surface of the sealing cover 11 is fixedly connected to an ink outlet pipe 111 that is connected to the ink supply pipe 2.

[0031] refer to Figure 1 and Figure 3 The sealing cover 11 has a raised platform integrally formed at the center of its upper surface, and a stirring paddle concealment groove 112 integrally formed on the lower surface of the raised platform. The stirring paddle concealment groove 112 is designed to ensure that the ink can be stirred and mixed, and at the same time, it can ensure that the sealing cover 11 can be driven down by the hydraulic actuation component 12 to deliver the ink to the ink supply pipe 2. The ink stirring component 14 includes a drive motor 141 fixedly connected to the upper surface of the sealing cover 11, a stirring shaft 142 coaxially fixedly connected to the output shaft of the drive motor 141, and a stirring paddle 143 fixedly connected to the stirring shaft 142 and located inside the stirring paddle concealment groove 112. A reduction motor is fixedly connected to the upper surface of the raised platform of the sealing cover 11, and the reduction motor is fixedly connected to the drive motor 141. One end of the stirring shaft 142 is sealed and the protruding platform through the sealing cover 11 is rotatably fixedly connected to the output shaft of the drive motor 141.

The stirring paddle 143 is fixedly connected to the periphery of the other end of the stirring shaft 142 and is located in the stirring paddle hiding groove 112.

[0032] refer to Figure 1The hydraulic operating assembly 12 includes two parts: a hydraulic cylinder 121 located around the ink barrel, a support frame 122, and a sealing cap connecting rod 123. The piston rod of the hydraulic cylinder 121 is fixedly connected to the support frame 122. One end of the sealing cap connecting rod 123 is fixedly connected to the support frame 122, and the other end is fixedly connected to the upper surface of the sealing cap 11.

[0033] refer to Figure 1 and Figure 3 A vacuum connector 113 is fixedly connected to the upper surface of the sealing cap 11, and the vacuum connector 113 is connected to the vacuum assembly 13. Specifically, the vacuum assembly 13 includes a vacuum pipe 131, a buffer tank 132, and a vacuum pump 133. One end of the vacuum pipe 131 is fitted with a quick-connect fitting, which connects the vacuum pipe 131 to the vacuum connector 112. The other end of the vacuum pipe 131 is also fitted with a quick-connect fitting, which connects the vacuum pipe 131 to the buffer tank 132. A vacuum pipe is fixedly connected to the top of the buffer tank 132, and this vacuum pipe is fixedly connected to the air inlet of the vacuum pump 133.

[0034] refer to Figure 1 and Figure 3 When the ink dispensing subsystem 1 is running, a gap is left between the sealing cover 11 and the ink surface in the ink tank. The vacuum assembly 13 performs vacuuming. Then, the hydraulic operating assembly 12 drives the sealing cover 11 to press down, so that the lower surface of the sealing cover 11 contacts the ink surface in the ink tank. The pressure continues to press down, causing the ink to fill the stirring paddle hidden groove 112. The ink stirring assembly 14 starts stirring and stirs for 3-5 minutes. The hydraulic operating assembly 12 drives the sealing cover 11 to rise, leaving a 1cm gap between the sealing cover 11 and the ink surface in the ink tank. The vacuum assembly 13 then performs vacuuming to defoam the ink in the ink tank. The hydraulic operating assembly 12 drives the sealing cover 11 to press down, causing the ink to fill the stirring paddle hidden groove 112. The pressure continues to press down, forcing the ink in the ink tank into the ink outlet pipe 111 and transmitting it to the ink supply pipe 2.

[0035] The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 4The terminal ink supply pipe 41 is fixedly connected to a pipe temperature sensor 412 located downstream of the control valve 411. The detection probe of the pipe temperature sensor 412 is located inside the terminal ink supply pipe 41. The pipe temperature sensor 412 allows for real-time monitoring of the ink output temperature. Based on the temperature displayed by the pipe temperature sensor 412, the heating power of the pipe heater 414 can be adjusted to precisely control the ink output temperature and quality. The terminal ink supply pipe 41 is also fixedly connected to a flow meter 413 located downstream of the control valve 411. The flow meter 413 is located downstream of the pipe temperature sensor 412, and its detection probe is located inside the terminal ink supply pipe 41. The terminal ink supply pipe 41 is also fixedly connected to a pipe heater 414 located upstream of the control valve 411. The pipe heater 414 provides thermal compensation for the transmitted ink, allowing for precise control of the ink output temperature.
