Description
Technical Field

Background
In the application of PCB pattern transfer, embedding passive elements and directly forming conductive lines, when a voltage with image information is applied to a spray head, the volume of a device storing liquid in the spray head changes suddenly, and ink is sprayed out from fixed small holes, so that characters are formed on a circuit substrate.
The PCB ink-jet printer ink separating and recovering device is used for recovering liquid during cleaning of a printer nozzle. When the printer nozzle is cleaned, the vacuum suction nozzle sucks the ink on the surface of the cleaning nozzle and flows into the recycling tubule; ink enters the main collecting pipe through the multipath recovery tubules and flows into the ink collecting cavity through the main collecting pipe; the separating ink baffle of the collecting cavity blocks the ink, so that the ink falls into the bottom of the collecting cavity. The air flows to the outlet pipe after being filtered by the filter element in the collecting cavity, and finally flows out of the vacuum fan at the tail end.
The existing PCB ink-jet printer is characterized in that the structural design of the separation and recovery system is not reasonable enough, the upward air flow takes away a lot of ink, the ink passes through the filter element and enters the outlet pipe, finally enters the bearing of the vacuum fan, and the ink entering the vacuum fan can corrode the parts of the vacuum fan. In addition, when the vacuum fan stops working in a certain time, the ink in the bearing is solidified, and the fan is prevented from rotating. When the fan is started again, the rotating shaft is blocked, so that the vacuum fan is damaged due to overload. There is a need to improve the structure of existing ink separation recovery systems.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
As shown in fig. 1 and 3, the ink recovery device of the PCB inkjet printer includes a main manifold 1, an ink discharge valve 2, an ink discharge tube 3, a chamber cover 4, a filter element 5, an ink collecting chamber 6, an outlet tube 7, a separation baffle 8 and an ink guide tube 9. The circular arc at the bottom of the ink collecting cavity 6 of the ink recycling device and the separating ink baffle plate 8 form a reverse elbow structure, when the mixture of ink and gas enters the ink collecting cavity 6 from the main collecting pipe 1, the flow at the reverse elbow structure generates direction change, the centrifugal force throws the ink in the mixture to the bottom of the ink collecting cavity 6, and the recycling effect of the ink is improved. Meanwhile, the ink recovery device improves the cross-sectional shape of a flow passage for the ink and gas mixture to enter the ink collecting cavity 6, the vertical wall surface of the separation ink baffle 8 and the vertical wall surface of the ink collecting cavity 6 are 120-140 degrees, preferably 130 degrees, the radius R of the cross-section semicircle at the bottom of the ink collecting cavity 6 is larger than 2 times the diameter D of the main collecting pipe 1, the vertical distance L between the bottom of the separation ink baffle 8 and the bottom of the ink collecting cavity 6 is far larger than the diameter D of the main collecting pipe 1, and the cross-sectional area of the flow passage for the ink and gas mixture to enter the ink collecting cavity 6 is gradually increased until the ink flows through the separation ink baffle 8.
As shown in fig. 2 and 4, the flow channel section gradually increases to gradually reduce the flow velocity, so that the influence of the separation effect caused by the ink falling from the separation ink baffle 8 due to the air flow carried away by local acceleration generated in the flowing process is avoided. In addition, the tail end of the lower edge of the separation ink baffle comprises an ink guide groove, the ink which is beaten on the separation ink baffle 8 along with the air flow can downwards flow into the ink guide groove along the separation ink baffle 8, then flows into the vertical branch pipes 9-2 of the ink guide pipes 9 at the two sides, and is converged into the ink discharge pipe 3 through the transverse branch pipe 9-1 in the groove at the bottom of the ink collecting cavity 6 to be discharged, so that the influence on the separation effect caused by the fact that the ink converged by the separation ink baffle 8 falls down and is taken away by the air flow is avoided; meanwhile, the middle of the flow channel section of the ink guide groove at the tail end of the separation ink baffle plate 8 is narrow, and the two sides are wide, so that the flow in the flow channel direction caused by the ink guide groove is reduced, and the phenomenon that the tail end of the ink guide pipe 9 disturbs the air flow of the ink discharge port of the ink discharge pipe 3 due to the high-speed air flow flowing into the ink guide pipe 9 is avoided. The ink guide tube 9 is respectively positioned in the grooves inside the cavity cover 4 and the ink collecting cavity 6, so that the pressure loss caused by the influence of the ink guide tube 9 on the air flow in the separation process is avoided.
The working principle of the invention is as follows:
when the separation system is in operation, the ink discharge valve 2 is in a closed state. Under negative pressure, the ink and gas mixture is collected in the main manifold 1 and flows to the ink collecting chamber 6. After being blocked by the separating ink baffle 8, the ink enters the ink collecting cavity 6 from the bottom of the ink collecting cavity 6. The gas flows upwards, under the action of gravity, a part of ink and a part of ink in the gas mixture fall to the bottom of the ink collecting cavity 6, and the other part of ink flows downwards into the grooves along the separating ink baffle plate 8 and then flows into the ink guide pipes 9 at the two sides, and finally flows into the ink discharge pipe 3 along the grooves at the bottom to be discharged. The gas continues to flow upwards, the ink which is not separated is filtered by the filter element 5, and finally the gas flows out of the outlet pipe 6 and flows to the vacuum fan.
When ink is recovered, the system stops working, and the ink discharge valve 2 is opened to discharge the collected ink.
The working principle is as follows: when passing through the reverse bend structure, the ink separation can be divided into two parts: a part of the ink impacts the separation ink baffle 8 and is attached to the separation ink baffle 8; a portion of the ink is deflected by the curved configuration of the bottom of the ink collection chamber 6 and the centrifugal force of the ink and gas mixture is deflected toward the bottom of the ink collection chamber 6 so that the ink is thrown to the bottom of the ink collection chamber 6. At the reverse bend, centrifugal force increases the flow velocity at the bottom of the ink collection chamber 6 and decreases the flow velocity at the wall of the separation baffle 8, thereby reducing the air flow to carry ink from the separation baffle 8 into the rise region.
The foregoing has outlined and described the basic principles, features, and advantages of the present invention. It should be understood by those skilled in the art that the foregoing embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention can be implemented by those skilled in the art without limiting the scope of the invention, therefore, all equivalent changes or modifications that are made according to the spirit of the present invention should be included in the scope of the present invention.
