Description

Technical Field

[0001] The present application relates to the technical field of ink recovery, and in particular to an ink recovery device for a water-based ink printing machine. Background Art

[0002] Ink is an important material used in printing. It displays patterns and texts on substrates through printing or spraying. The ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. It is composed of binders (resins), pigments, fillers, additives and solvents, etc. It will require a recycling and processing device after use.

[0003] The published patent with authorization announcement number CN220865021U describes an environmentally friendly ink recovery device for a printing press, comprising a recovery hopper connected to the printing press, a recovery box with an open top disposed below the recovery hopper, a delivery pipe disposed at the bottom of the recovery hopper, a feeding pipe disposed on the side of the delivery pipe, a drive rod rotatably mounted within the recovery box, a filter element and an agitator disposed on the drive rod that can move up and down, a stirring mechanism disposed below the filter element at a predetermined height, and a motor connected to the drive rod mounted at the bottom of the recovery hopper. The present invention accelerates the dissolution of water-based ink lumps by providing the feeding pipe, delivery pipe, motor, drive rod, filter element, and agitator. By configuring the filter element to be movable up and down, the water-based ink is more ventilated, thereby suppressing the agglomeration of the water-based ink in the recovery box. The stirring mechanism is provided to continuously stir the water-based ink in the recovery box, effectively preventing the water-based ink from settling.

[0004] When the above device is implemented, the efficiency of dissolving the water-based ink blocks is slow, which in turn causes the overall recycling process to be slow. In addition, during recycling, materials are likely to remain on the inner wall of the recycling box, causing losses and incomplete recycling. Utility Model Content

A round rod 14 is fixedly connected to the outer edge of the round rod 14. A connecting pipe 16 is fixedly connected to the outer edge of the connecting pipe 16. A plurality of water spray pipes 17 are fixedly installed in parallel on the outer edge of the connecting pipe 16. A circular ring 18 is fixedly installed on the bottom of the connecting pipe 16. A filter screen 19 is fixedly installed on the inner wall of the circular ring 18. A water inlet pipe 20 is inserted into the inner wall of the top of the stirring rod 10

[0029] See Figure 3 and Figure 4 A motor 11 is fixedly installed on the top of the sealing cover 2, and a gear 12 is also fixedly installed on the power output shaft of the motor 11, and the two gears 12 are meshed with each other, so that the operation of the driving motor 11 can drive one of the gears 12 to rotate, and then the gear teeth can be used to transmit the rotational force to the other gear 12, thereby driving the stirring rod 10 to rotate.

[0030] See Figure 3 and Figure 4A transmission wheel 8 is also fixedly installed on the outer edge of the stirring rod 10. The two transmission wheels 8 are in the same plane. The transmission belt 9 is sleeved on the inner walls of the two transmission wheels 8, so that when the stirring rod 10 rotates, the transmission belt 9 can be used to transmit the rotational force to the other transmission wheel 8, and then drive the rotating rod 6 and the crushing knife 7 to rotate, so as to achieve the crushing of the solidified water-based ink block placed in the inner cavity of the feeding bin 4, thereby ensuring its efficiency during subsequent dissolution.

[0031] See Figure 1 - Figure 3 Two plug-in plates 3 are symmetrically fixed on the bottom of the sealing cover 2, and two card slots that are adapted to the shape of the plug-in plates 3 are symmetrically opened on the top of the recovery tank 1. The two plug-in plates 3 are inserted into the inner walls of the card slots, so that the plug-in plates 3 can be used to match the card slots to connect the recovery tank 1 and the sealing cover 2, thereby ensuring that the sealing cover 2 is stably set on the top of the recovery tank 1, and thereby ensuring that the sealing cover 2 will not easily shake or deviate from its position when the motor 11 is at the top of the sealing cover 2.

[0032] See Figure 3 and Figure 4 A scraper 15 is fixedly installed on the outside of the round rod 14, and the outer side of the scraper 15 fits with the inner wall of the recovery tank 1, so that when the stirring rod 10 rotates to stir the ink in the inner cavity of the recovery tank 1, it can drive the scraper 15 to rotate together, and then the ink adhering to the inner wall of the recovery tank 1 can be scraped off, ensuring that it fully participates in the stirring and improving the thoroughness of the discharge when discharging.

[0033] See Figure 2 - Figure 4 The outer diameter of the ring 18 is adapted to the inner wall diameter of the recovery tank 1. A discharge pipe is fixedly installed on the inner wall of the recovery tank 1, and a control valve is fixedly installed on the inner wall of the discharge pipe, so that the ring 18 can rotate stably on the inner wall of the recovery tank 1, ensuring that the scraper 15 and the connecting pipe 16 will not easily shake or shift in position when driving the ring 18 to rotate.

[0034] See Figure 3 and Figure 4 A bracket 21 is fixedly installed on the top of the sealing cover 2. A rotating hole is opened on the inner wall of the bracket 21. The stirring rod 10 is adapted to be rotatably connected to the inner wall of the rotating hole, so that the stirring rod 10 can be positioned during rotation, thereby ensuring the stability of the stirring rod 10 during rotation, and further ensuring that it can rotate stably in a vertical state.

[0035] Working principle: When using the device, first, the motor 11 can be driven to drive the gear 12 to rotate, and then the gear teeth can be used to transmit the rotational force to another gear 12, thereby driving the stirring rod 10 to rotate. When the stirring rod 10 rotates, the transmission belt 9 can be used to transmit the rotational force to another transmission wheel 8, thereby driving the rotating rod 6 and the crushing knife 7 to rotate, and then the ink to be recycled can be placed in the inner cavity of the feeding bin 4, and added to the inner cavity of the recovery tank 1, so that the crushing knife 7 can be used to break the solidified water-based ink blocks placed in the inner cavity of the feeding bin 4 to ensure its efficiency during subsequent dissolution. After the ink is added, the additive that inhibits the solidification of the water-based ink can be added to the inner cavity of the recovery tank 1, and then the stirring rod 10 can be used to drive the stirring blade 13 to rotate, so that the ink and the additive can be stirred. To ensure uniform mixing, it can also drive the ring 18 and the filter screen 19 to rotate, ensuring that the dissolved ink can be filtered through the filter screen 19, and then discharged to the outside through the discharge port for collection. When the stirring rod 10 rotates to stir the ink in the inner cavity of the recovery tank 1, it can drive the scraper 15 to rotate together, and then the ink adhering to the inner wall of the recovery tank 1 can be scraped off, ensuring that it fully participates in the stirring, and can improve the thoroughness of the discharge when discharging. At the same time, the end of the water inlet pipe 20 away from the stirring rod 10 can be connected to the pump, and then the cleaning water can be discharged into the inner cavity of the stirring rod 10 and the connecting pipe 16, and then the inner wall of the recovery tank 1 can be rinsed by the water spray pipe 17, and the stirring rod 10 drives the scraper 15 and the connecting pipe 16 to rotate synchronously to rotate and scrape the inner wall of the recovery tank 1 to ensure thorough cleaning.
