Description

Technical Field

[0001] The invention relates to the field of decorative paper printing, in particular to an ink circulation device for decorative paper printing. Background Art

[0002] Decorative paper is a raw material required in some building materials products, such as low-pressure boards, high-pressure boards, and fireproof boards used in furniture and cabinets. Decorative paper mainly provides decorative patterns and covers to prevent the leakage of ground glue. When processing decorative paper, it is necessary to immerse the decorative paper in the ink tank for smearing. When smearing the decorative paper, the excess ink will be circulated through the circulation device. When the existing ink circulation device is in use, the ink is transported to the filter box through the leakage groove opened on the lower surface of the ink tank, and then the impurities in the ink are filtered out through the filter screen inside the filter box. The filtered ink will be transported into the mixing barrel by the delivery pump. In the ink tank, the ink is fully stirred by a stirring mechanism to make the ink fully blended, and then the ink is transported back to the ink tank, thereby allowing the ink to be recycled; however, when the ink tank is actually used, the ink in the ink tank will precipitate to form some ink particles, and these precipitated ink particles will adhere to the inner wall of the ink tank. The existing ink circulation device cannot clean the ink particles attached to the inner wall of the ink tank. Secondly, when the ink is filtered through the filter net in the filter box, some precipitated particles will also be filtered out, resulting in ink waste.

[0042] Working principle of the present invention: after the decorative paper is immersed in the ink tank 1 for smearing, when the ink in the ink tank 1 needs to be processed; the electric push rod 13 is started to drive the moving plate 3 to move, and the movement of the moving plate 3 drives the piston plate 4 to move until the side of the moving plate 3 away from the piston plate 4 contacts the inner wall of the ink tank 1, as shown in the attached figure. Figure 3As shown, at this time, the ink in the ink tank 1 will gradually flow into the filter box 10 through the leakage tank 8 and the connecting pipe 9, and the ink in the filter box 10 can be filtered through the filter screen 15. At the same time, the ink pump 36 is started and the ink filtered by the filter screen 15 is pumped into the storage barrel 6 through the pipe 1 37 and the pipe 2 38, and the ink pump 36 can be stopped at any time according to the actual situation of the ink in the filter box 10; when processing the ink, starting the servo motor 27 will drive the stirring shaft 24 to rotate, and the rotation of the stirring shaft 24 will drive The stirring blade 25 and the scraper 26 rotate, the stirring blade 25 rotates to stir the ink in the storage barrel 6 so that the ink is fully blended, and the scraper 26 rotates to continuously clean the inner wall of the storage barrel 6; the stirring shaft 24 rotates and drives the transmission rod 31 to rotate under the transmission of the two sets of sprocket wheels 32 and the chain 33, the transmission rod 31 rotates to drive the hexagonal rod 35 to rotate, the hexagonal rod 35 rotates to drive the stirring shaft 1102 to rotate, the stirring shaft 1102 rotates to rotate multiple sets of stirring blades 1104 and scrapers 1105, stirring The rotation of blade 1104 will continuously stir the ink in the filter box 10 (and above the filter screen 15) for the first time, stir and fuse the solid particles precipitated in the ink, and prevent the ink solid particles with large volume from being filtered by the filter screen 15, and the rotation of scraper 1105 will continuously stir the impurities filtered by the filter screen 15, and prevent the impurities from not moving for a long time. As the number of impurities increases, the filter screen 15 is blocked; when the ink in the ink tank 1 is drained, the servo motor 505 is started and the two sets of sprockets 503 and chain Under the transmission of the screw rod 504, the two sets of screws 501 will be driven to rotate in the same direction and at the same speed, thereby driving the cleaning plate 2 to move. Since the cleaning plate 2 is in close contact with the bottom end of the inner wall of the ink tank 1 and the front and rear ends of the inner wall of the ink tank 1, the ink particles precipitated at the bottom end and the front and rear ends of the inner wall of the ink tank 1 will be cleaned up during the movement of the cleaning plate 2, and these cleaned ink particles will be pushed toward the leakage tank 8 until the cleaning plate 2 contacts the two sets of limit blocks 502 close to the electric push rod 13, and the servo motor 505 stops working. Figure 3As shown, after the cleaning block 705 moves downward, it will contact the cleaning plate 2 and the side of the piston plate 4 that contacts the ink at the same time. At this time, the stirring shaft 24 rotates and under the transmission of the two sets of sprockets 29 and the chain 2 30, it will drive the reciprocating screw 702 to rotate. The rotation of the reciprocating screw 702 will drive the lifting frame 703 to move up and down continuously along the two sets of guide rods 704. The up and down movement of the lifting frame 703 will drive the cleaning block 705 to move up and down, and the up and down movement of the cleaning block 705 will continuously clean the cleaning plate 2 and the side of the piston plate 4 that contacts the ink, and clean up the ink particles attached to the side of the cleaning plate 2 and the piston plate 4 that contacts the ink. Under the shaking of the continuous up and down movement of the cleaning plate 2, the ink particles all fall into the connecting pipe 9 through the leakage groove 8, and flow into the filter box 10 driven by the flow of ink in the connecting pipe 9. When the ink processing work is completed After completion, open the solenoid valve on the discharge pipe 39, and the ink in the storage barrel 6 will be discharged into the inner cavity of the ink tank 1 through the discharge pipe 39. When the ink in the ink tank 1 reaches a certain amount, close the solenoid valve on the discharge pipe 39, so as to realize the recycling of the ink; when the circulation work is completed, start the electric push rod 21 to drive the horizontal plate 19 to move upward, and the upward movement of the horizontal plate 19 will drive the lifting block 1101 and the vertical bar 20 to move upward. The upward movement of the vertical bar 20 makes the vertical bar 20 separate from the surface of the collection box 16, and the upward movement of the lifting block 1101 will drive the stirring shaft 1102, multiple groups of stirring blades 1104 and the scraper 1105 to separate from the inner cavity of the collection box 16. At this time, the operator can draw out the collection box 16, and then clean the impurities in the collection box 16 and the impurities on the filter 15.

[0043] It should be noted that when the ink in the ink tank 1 is drained and the ink is flush with the leakage tank 8, the ink pump 36 is stopped so that the ink particles cleaned by the cleaning block 705 from the cleaning plate 2 and the side of the piston plate 4 that contacts the ink can fall into the ink, ensuring that a certain amount of ink is maintained in the connecting tube 9. The flow of ink in the connecting tube 9 can smoothly drive the ink particles to flow into the filter box 10. When the cleaning block 705 has finished the cleaning work, the ink pump 36 is restarted.

[0044] It should be noted that the servo motor 1 505 and the servo motor 2 27 are both prior art, and both use servo motors with self-locking structures.

[0045] It should be noted that the material of the piston plate 4 is the same as that of the piston used in the syringe, and has good sealing properties.
