[0002] Water-based ink is referred to as water-based ink for short. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through composite grinding. In the production process of water-based ink, the raw materials need to be ground. In the process of grinding, some particles cannot be ground and crushed. Therefore, a particle screening machine is needed to screen them and separate the water-based ink and the particles.

[0003] In the prior art, when screening, it is necessary to continuously add ink into the screening machine. However, it is inconvenient to remove the large particles screened out during the screening process, so they will accumulate on the screen, causing blockage and affecting the subsequent screening efficiency. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 , a high-efficiency particle screening machine for water-based ink production, comprising a base 1, a fixed frame 2 is mounted on the base 1 through a vibration motor, a screen 3 is fixedly mounted in the fixed frame 2, and a hopper 4 is fixedly mounted on the base 1 through a bracket;

[0021] During the screening process, ink is added to the screen 3 through the hopper 4, and then the fixed frame 2 is driven to vibrate by the vibration motor to achieve screening of the ink.

[0022] A scraper 5 is slidably provided on the upper surface of the screen 3, and the lower surface of the scraper 5 is in sliding contact with the upper surface of the screen 3. A metal block 6 is fixedly installed on the upper end of the scraper 5. An L-shaped moving rod 7 is installed on the hopper 4 through a reciprocating assembly. A magnet 8 is fixedly installed on the lower end of the moving rod 7. The magnet 8 and the metal block 6 are on the same horizontal plane. A blocking assembly for blocking the hopper 4 is provided at one end of the moving rod 7;

[0023] The reciprocating assembly includes a driving motor 9 fixedly mounted on the side of the hopper 4, a reciprocating screw rod 10 rotatably mounted on the side of the hopper 4, and a moving block 11 threadedly sleeved on the reciprocating screw rod 10, the output shaft of the driving motor 9 is fixedly connected to one end of the reciprocating screw rod 10, and the moving block 11 is fixedly connected to the moving rod 7;

[0024] The driving motor 9 can drive the reciprocating screw 10 to rotate on the hopper 4, and then drive the moving block 11 to move through the reciprocating screw 10, so as to drive the moving rod 7 to reciprocate horizontally through the moving block 11.

[0025] The blocking assembly includes a slider 12 slidably mounted on the moving rod 7 through an elastic component, a stopper 13 fixedly mounted on one end of the moving rod 7, and an L-shaped blocking plate 14 fixedly mounted on the slider 12. The upper surface of the blocking plate 14 is in sliding contact with the lower end of the hopper 4. The elastic component includes a fixed block 15 fixedly mounted on the moving rod 7 and a telescopic spring 16 sleeved on the moving rod 7. Both ends of the telescopic spring 16 are fixedly connected to the slider 12 and the fixed block 15 respectively.

[0026] When the moving rod 7 moves back and forth, under the action of the elastic force of the telescopic spring 16, the blocking plate 14 will be driven to move through the slider 12 until the blocking plate 14 blocks the lower end of the hopper 4. At this time, one end of the blocking plate 14 will contact with the hopper 4 to limit the movement of the blocking plate 14. When the moving rod 7 continues to move, relative sliding occurs between the moving rod 7 and the slider 12, and the telescopic spring 16 is compressed. When the blocking plate 14 blocks the lower end of the hopper 4, the magnet 8 installed at one end of the moving rod 7 just contacts with the metal block 6. When the moving rod 7 continues to move, the scraper 5 will be driven to move horizontally on the screen 3 through the magnet 8 and the metal block 6, so that large particles on the screen 3 are discharged from one side of the screen 3, preventing a large amount of particles from accumulating on the screen 3 and causing blockage, thereby effectively improving the subsequent screening efficiency.

[0027] When the moving rod 7 drives the scraper 5 to move back, the telescopic spring 16 will slowly recover, and the blocking plate 14 will still block the hopper 4 until the scraper 5 contacts the fixed frame 2, limiting the continued movement of the scraper 5. At this time, the magnet 8 will separate from the metal block 6, and the telescopic spring 16 will just recover. The slider 12 contacts the block 13, and then the moving rod 7 will drive the blocking plate 14 to move together during the movement, thereby opening the hopper 4 again. At this time, the ink in the hopper 4 will fall onto the screen 3 and continue to be screened.

[0028] A sealing gasket is fixedly installed on the upper surface of the blocking plate 14. The sealing gasket is made of rubber. When the blocking plate 14 blocks the hopper 4, the sealing gasket can increase the sealing between them, thereby preventing the ink in the hopper 4 from leaking out.

[0029] The width of the fixed frame 2 is greater than the width of the screen 3. A collecting frame 17 is fixedly installed on the base 1. Two collecting slots are arranged in the collecting frame 17. One of the two collecting slots is located directly below the screen 3, and the other is located on one side of the screen 3. During screening, the ink that can pass through the screen 3 will be collected in one of the collecting slots, while the large particles will be collected in the other collecting slot.

[0030] In the utility model, when the reciprocating component drives the moving rod 7 to move toward the hopper 4, it will first block the lower end of the hopper 4 through the blocking component, and then drive the scraper 5 to move on the screen 3 through the magnet 8 and the metal block 6 to export large particles. When the moving rod 7 moves away from the hopper 4, it will first drive the scraper 5 back to the initial position, and then release the blockage of the hopper 4, so as to continue to realize the feeding and screening. During the screening process, the large particles on the screen 3 can be conveniently exported, thereby preventing a large amount of particles from accumulating on the screen 3 and causing blockage, thereby effectively improving the subsequent screening efficiency.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
