[0019] The utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the utility model are shown. The utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the utility model to the skilled person.

[0020] Example 1: a packaging printing ink supply device, such as Figure 1 , Figure 2 and Figure 4As shown, including organic frame 1, frame 1 as the main support structure, frame 1 top left and right symmetrically provided with two fixed seat 2, the two fixed seat 2 not only stable the overall structure of the device, but also provides installation space for other components of the device, ink fountain 3 transverse frame between the two fixed seat 2 lower part, its upper front side is provided with a slot, easy to enter the web roll 4, ink fountain 3 top rear side is also provided with mounting seat 31 left and right symmetrically, mounting seat 31 for installation of the doctor blade or roller ink reserved, according to the processing conditions, choose, equipped with this component is to remove the excess ink adhering to the surface of the web roll 4;

[0021] Among them, the web roll 4 rotationally arranged between the upper part of the fixed seat 2, and with the ink fountain 3 keep the same arrangement direction, the lower part of the web roll 4 through the slot on the ink fountain 3 into the ink fountain 3 inside, while the slot edge on the ink fountain 3 and the outside of the web roll 4 keep close but not in contact state, such design not only ensures the effective transmission of ink, but also avoids unnecessary friction and loss;

[0022] In the lower part of the frame 1, provided with ink storage cylinder 5 as the main storage container of ink, ink storage cylinder 5 is equipped with ink injection port and ink discharge port, and the two ports in the normal state to ensure the sealing and stability of the ink, frame 1 side is provided with pump body 51, the input end of the pump body through the pipeline and the lower space in the ink storage cylinder 5 is connected, while the output end is connected with the side of the ink fountain 3 through the pipeline and the communication, such design makes the pump body 51 can efficiently transmit the ink in the ink storage cylinder 5 to the ink fountain 3, for printing process to provide stable ink supply, while in the upper part of the ink storage cylinder 5 away from the pump body 51, the side is provided with pump body 52, the input end of the pump body 52 and the bottom side of the ink fountain 3 is connected and communicated, while the output end is connected with the upper space in the ink storage cylinder 5, such design makes the pump body 52 can be used in the ink fountain 3 back to the ink in the ink storage cylinder 5, forming the circulation of ink, it is worth mentioning that the pump body 51 and pump body 52 are metering pump, can accurately control the flow and flow rate of ink, ensure the stability and continuity of the ink supply process.

[0023] Specifically: in the printing process, the pump body one 51 starts, the ink in the ink storage cylinder 5 is transmitted to the ink fountain 3 through the pipeline. The lower part of the screen roller 4 enters the inside of the ink fountain 3 through the slot on the ink fountain 3 during rotation, and fully contacts with the ink in the ink fountain 3. Since the ink fountain 3 and the screen roller 4 keep close but not contact, therefore the ink can be uniformly attached to the surface of the screen roller 4. Subsequently, the screen roller 4 carries the ink to the printing area for printing. At the same time, the pump body two 52 starts, the used ink in the ink fountain 3 is transmitted back to the ink storage cylinder 5 through the pipeline, forming the circulation flow of the ink. By setting the closed ink storage cylinder 5 and the semi-closed ink fountain 3, and matching the two pump bodies one 51 and pump body two 52 for ink supply and ink circulation respectively, it helps to keep the viscosity of the ink stable, avoiding the change of the ink due to exposure to air during printing. Secondly, it ensures the continuity and stability of the ink during ink supply, improves the printing efficiency.

Specifically, the detector 6 is symmetrically added to the top front side of the ink fountain 3, and the detection heads of the two detectors 6 are both directed to the side of the screen roller 4. Such design enables the detector 6 to scan and detect the color of the ink adhered to the surface of the screen roller 4 in real time, quickly and accurately capturing the subtle changes of the ink color. When color difference is found on the surface of the screen roller 4, the signal is fed back in time, thereby ensuring the stability and consistency of the ink color during printing.

[0025] At the same time, the sensor 61 is also arranged on the pipeline connected to the input end of the pump body two 52. The main function of this sensor 61 is to detect the pressure of the fluid in the pipeline. By monitoring the ink pressure under certain flow and speed, the viscosity of the ink can be indirectly known. This design helps to find the fluctuation of the ink viscosity in time, providing important basis for adjusting the ink ratio and printing parameters, and thereby ensuring the stability of the printing quality.

[0026] In addition, as shown in Figures 2-3As shown, the utility model still adds the stirring part 71 and corresponding stirring motor 7 in the ink storage cylinder 5, the stirring motor 7 is arranged in one end of ink storage cylinder 5, its output shaft is worn into the ink storage cylinder 5, and one end of the stirring part 71 that is horizontally and rotatably arranged in the ink storage cylinder 5 is fixedly connected, when the stirring motor 7 starts, it will drive the stirring part 71 to rotate in the ink storage cylinder 5, thereby the ink in the cylinder is mixed and stirred uniformly, such design not only ensures the full dispersion of each component of ink, avoids the problem of local concentration unevenness, effectively breaks the precipitation and agglomeration in the ink, keeps the good fluidity of ink.

[0027] In addition, in order to further optimize the ink environment in the ink fountain 3, such as Figure 4 As shown, the utility model still arranges the main gas pipe 8 in the ink fountain 3 lower part horizontally, one end of the main gas pipe 8 is worn from one side of the ink fountain 3, and is connected with the joint 81 on the side of wearing, is convenient for connecting with external gas source, simultaneously, the main gas pipe 8 still arranges several evenly spaced branch pipes 82, these branch pipes 82 all communicate with the main gas pipe 8, such design makes gas be able to be evenly distributed to each corner in the ink fountain 3 through the main gas pipe 8 and branch pipe 82, forms the bubble in the ink through the gas, and the tiny bubble rises and breaks in the ink, produces a kind of slight stirring effect, further improves the uniformity and fluidity of ink.
