Description

Technical Field

[0001] The present application relates to the technical field of ink printing, and in particular to an ink supply device for a printing ink pipeline. Background Art

[0002] Since there are multiple ink printers installed on the printing production line of the printing factory, in order to improve the efficiency of ink printing, the ink is mainly supplied through ink pipelines. The commonly used printing ink pipeline ink supply device is mainly composed of a sealed pipeline, a diversion interface and a flow control valve body. The end of the sealed pipeline is connected to the ink suction pump. The printing ink in the ink barrel is filled into the sealed pipeline through the suction pump. After the diversion of the diversion interface and the flow control of the flow control valve body, the printing ink enters the ink printer quantitatively. Although the above common printing ink pipeline ink supply method saves labor and can improve the efficiency of ink printing, it still has the following shortcomings in actual application:

[0003] As the ink is stored in the oil barrel and remains stationary, a certain amount of impurities such as suspended particles will appear inside. These impurities will directly enter the ink printing machine through the flow control valve, which will not only affect the printing quality of the ink printing machine, but the long-term accumulation of impurities will also easily affect the flow control accuracy of the flow control valve, thereby causing ink supply failure.

[0035] The present application embodiment discloses a printing ink pipeline ink supply device, referring to Figure 1 , including an ink supply pipe 1, a diversion tee pipe 12, a diversion assembly, a filtering mechanism 3 and a liquid supply assembly. The ink supply pipe 1 is placed horizontally, and a connecting flange 14 is installed at one end of the ink supply pipe 1. The specific connecting flange 14 can be fixed by welding, bolts, etc., which is not limited here.

[0036] The flow dividing tee pipe 12 includes a first conducting port, which is connected to the end of the ink supply main pipe 1 away from the connecting flange 14. Two groups of flow dividing components are provided, and each group includes a branch pipe 2 and a flow diversion expansion port 5. The branch pipe 2 is vertically arranged, and a manual valve 4 is fixedly installed in the middle of the branch pipe 2. The bottom end of the branch pipe 2 is fixedly provided with an external threaded joint 13.

[0037] The flow guide expansion port 5 is fixedly connected to the bottom of one side of the branch pipe 2, and the printing ink in the ink supply main pipe flows into the branch pipe 2 through the first guide port and then flows out through the flow guide expansion port 5. One end of the flow guide expansion port 5 is fixedly connected to a flow guide pipe 6, which is arranged horizontally, and a one-way valve 8 is fixedly installed in the middle of the flow guide pipe 6. The end of the flow guide pipe 6 away from the flow guide expansion port 5 is fixedly connected to a converging three-way pipe 7. The filtering mechanism 3 is fixedly installed at the bottom of the branch pipe 2, and is used to filter particulate impurities in the printing ink.

[0038] The ink supply main pipe 1 is installed at the liquid outlet of the ink supply pump through the connecting flange 14. The printing ink flows into the diversion tee pipe 12 through the ink supply main pipe 1. At the same time, only one of the two manual valves 4 is opened. The printing ink enters the diversion expansion port 5 along the branch pipe 2 of the opened manual valve 4, and then enters the diversion pipe 6, and enters the liquid supply component through the one-way valve 8 to complete the ink supply.

[0039] Reference Figure 1The liquid supply assembly includes a supply pipe 9 and an electronic ink flow control valve 10 fixedly installed at the bottom of the supply pipe 9. A branch interface 11 is fixedly installed at the liquid outlet of the electronic ink flow control valve 10. The ink pipe of the ink printer is directly connected to the branch interface 11. The filtered printing ink enters the electronic ink flow control valve 10 along the supply pipe 9, and after flow control, enters the ink printer.

[0040] Reference Figure 3 and Figure 4 The filtering mechanism 3 includes a metal filter screen cylinder 31 and an internal thread sealing cap 32 fixedly arranged at the bottom end of the metal filter screen cylinder 31 , a sealing gasket 37 is fixedly arranged on the inner side wall of the internal thread sealing cap 32 , and a filter gauze bag 34 is arranged on the inner side of the metal filter screen cylinder 31 .

[0041] Reference Figure 2 and Figure 3 In order to facilitate the installation and fixation of the metal filter cylinder 31, a Velcro 33 is fixedly provided on the outer side of the top of the metal filter cylinder 31, and a folded expansion opening 36 is fixedly provided on the top of the filter gauze bag 34. A Velcro mother sticker 35 is fixedly provided on the outer side of the folded expansion opening 36. The Velcro mother sticker 35 matches the Velcro 33. The internal thread sealing cap 32 is threadedly provided on the external thread joint 13. The outer diameter of the metal filter cylinder 31 matches the inner diameter of the branch pipe 2.

[0042] After entering the branch pipe 2, the printing ink will first enter the filter gauze bag 34, intercept the suspended particulate matter in the printing ink through the filter gauze bag 34, and then pass through the metal filter cylinder 31. The filtered printing ink enters the diversion pipe 6 through the diversion expansion port 5 to improve the cleanliness of the printing ink. The staff can regularly unscrew and remove the internal thread sealing cap 32, then pull out the metal filter cylinder 31 as a whole, tear off the folding expansion port 36, and then pull out the filter gauze bag 34 as a whole, put the new filter gauze bag 34 into the metal filter cylinder 31, fold the folding expansion port 36, and stick the Velcro mother patch 35 on the Velcro child patch 33. At this time, the filter gauze bag 34 is installed, and the metal filter cylinder 31 is reinserted into the branch pipe 2, and the internal thread sealing cap 32 is screwed on.

[0043] The implementation principle of the embodiment of the present application is: the ink is filtered through the filtering mechanism 3, and the filtered ink flows into the branch pipe 2 and then flows into the guide pipe 6 through the guide expansion port 5, and then flows into the supply pipe 9 through the converging tee pipe 7. When the branch pipe 2 on one side needs to be cleaned, the manual valve 4 on the other branch pipe 2 is opened first, and then the manual valve 4 on the branch pipe 2 is closed. At this time, the redirection of the printing ink is realized. One is shut off for cleaning, and the other is continuously conducting the printing ink. The cleaning and maintenance of the filtering mechanism 3 can be realized under the condition of uninterrupted supply of printing ink.
