Description

Technical Field

[0001] The utility model relates to the technical field of ink grinding machines, in particular to an ink grinding machine with a magnetic filter. Background Art

[0002] An ink grinder is a device used to crush ink particles into fine particles to improve the quality and stability of the ink. Existing ink grinders mainly include three-roller grinders, bead mills and pin-type sand mills. During the ink grinding process, the grinding sheet in the grinding roller is usually made of metal. The advantages of metal are high wear resistance, high hardness and low cost. However, the metal grinding sheet will release trace metal particles during the physical contact with the ink, thereby generating impurities. There is a technology in the prior art to replace the metal grinding sheet with a ceramic grinding sheet, but the ceramic grinding sheet is relatively expensive and not suitable for promotion. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an ink grinding machine with a magnetic filter.

[0004] In order to achieve the above-mentioned purpose, an ink grinder with a magnetic filter is designed, including a grinding roller, a hopper and a discharging device arranged below the grinding roller, and also a magnetic filter. The magnetic filter includes a barrel-shaped container, and the two sides of the barrel-shaped container are respectively connected to the hopper and the conveying pump arranged below the grinding roller through pipes, and the other side of the conveying pump is connected to the discharging device. A container cover is provided on the top of the barrel-shaped container, and a plurality of through holes are opened on the container cover, and a magnetic rod is inserted into each through hole.

[0005] Preferably, a plurality of through holes are arranged at the center of the container cover and along the circumference of the center, a magnetic rod is inserted into each through hole, and a gap is left between the magnetic rod and the bottom of the barrel-shaped container.

[0006] Preferably, the container cover is detachably connected to the barrel-shaped container.

[0007] Compared with the prior art, the utility model has the advantages of reducing the metal remaining in the ink by means of the magnetic rod pins, and the ink flows in the pipeline for a long time so that the multi-row hinged magnetic string rods completely encompass the entire flow cross section of the circulation, thereby adsorbing the ferromagnetic impurities to be passed through the ink on the multiple arranged magnetic string rods without any residue.

[0012] The utility model is further described below in conjunction with the accompanying drawings. The structure and principle of the utility model are very clear to people in the field. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] like Figure 1 As shown, the utility model discloses an ink grinding machine with a magnetic filter 1, comprising a grinding roller 2, a hopper 3 and a discharging device 5, and also comprising the magnetic filter 1.

[0014] The hopper 3 is arranged below the grinding roller 2. The grinding roller 2 and the discharging device 5 are both prior art and will not be described in detail here.

[0015] like Figure 2-3 As shown, the magnetic filter 1 is located below the grinding roller 2, and the magnetic filter 1 includes a barrel-shaped container 10, and pipes 6 are respectively provided on both sides of the barrel-shaped container 10. The two pipes 6 are respectively connected to the hopper 3 and the conveying pump 4, and the other side of the conveying pump 4 is connected to the discharging device 5.

[0016] A container cover 8 is provided on the top of the barrel-shaped container 10 , and the container cover 8 is detachably connected to the barrel-shaped container 10 . A plurality of through holes 9 are distributed in the center of the container cover 8 and along the circumference of the center. A magnetic rod 7 is inserted into each through hole 9 , and a gap is left between the magnetic rod 7 and the bottom of the barrel-shaped container 10 .

[0017] After the ink ground by the grinding roller 2 enters the hopper 3, it flows into the barrel container 10 of the magnetic filter 1 through the pipe 6. The magnetic rod 7 inside the container can absorb iron impurities in the ink to improve the quality of the ink. The adsorbed ink then enters the discharge device 5 through the pipe 6.

[0018] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
