[0002] Anti-counterfeiting ink is one of the important methods in the field of anti-counterfeiting. It can effectively cooperate with anti-counterfeiting measures such as paper anti-counterfeiting and laser holographic anti-counterfeiting to achieve a relatively satisfactory anti-counterfeiting effect. Its specific implementation is mainly to print on tickets, product trademarks and packaging. At present, the types of anti-counterfeiting inks mainly include: ultraviolet fluorescent ink, sunlight-excited color-changing anti-counterfeiting ink, thermosensitive anti-counterfeiting ink, magnetic ink, biochemical reaction ink, etc. Ink is a viscous body formed by mixing resin, pigment, filler and other auxiliary ingredients, and its mixing is mainly completed by stirring and dispersing.

The mixing of the water-based anti-counterfeiting ink raw materials inside can easily produce bubbles. The bubbles will hinder the transfer of the ink, resulting in missing patterns in subsequent printings, thus producing defective products. Utility Model Content

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figures 1 to 3The utility model provides a technical solution: a mixing device with a bubble elimination function, comprising a mixing box 1, an ink raw material feeding box 3 is fixedly installed on the top of the mixing box 1, a feeding port 4 is installed on the top of the ink raw material feeding box 3, the feeding port 4 is inclined upward and connected to the cylindrical cavity 31, and the angle setting of the feeding port 4 is conducive to the inclined feeding of the water-based anti-counterfeiting ink raw material.
[0019] A cylindrical cavity 31 is provided inside the ink raw material feed box 3, the bottom of the cylindrical cavity 31 is connected to the mixing box 1, an ink discharge trough 2 is installed at the bottom of the mixing box 1, a control valve is installed on the ink discharge trough 2, and a main shaft 6 is rotatably connected to the mixing box 1 through a bearing.
[0020] A first mixing rod 61 is fixedly installed on the outside of the main shaft 6, and a driving motor 5 is installed at one end of the main shaft 6. The model of the driving motor 5 can be selected according to the actual working conditions. The rotation of the first mixing rod 61 can stir the aqueous anti-counterfeiting ink raw material to generate centrifugal force, thereby removing bubbles.
[0021] A first rotating shaft 7 is rotatably connected to the main shaft 6 located in the cylindrical cavity 31, and a rotating plate 71 is fixedly connected to the outer side of the first rotating shaft 7. A plurality of rotating plates 71 are provided, and the ends of the plurality of rotating plates 71 are fitted with the cylindrical cavity 31. A relatively closed structure for feeding is formed between the rotating plate 71 and the cylindrical cavity 31, thereby reducing the entry of air through the top opening of the mixing device.
[0022] A first drive connection group 72 is installed between the first rotating shaft 7 and the main shaft 6, and the first drive connection group 72 is connected and driven by a first belt group. A second rotating shaft 8 is rotatably connected to the mixing box 1 below the main shaft 6 through a bearing, and a second mixing rod 81 is fixedly connected to the outer side of the second rotating shaft 8. A second drive connection group 82 is installed between the second rotating shaft 8 and the main shaft 6, and the second drive connection group 82 is connected and driven by a second belt group.

The vacuum suction port 91 is fixedly connected to the connecting pipe interface of the vacuum pump 9. The air in the mixing box 1 is sucked through the vacuum suction port 91 by starting the vacuum pump 9. Under the condition of reducing the pressure, the air pressure inside the bubbles will increase, causing the bubbles to expand and eventually burst, thereby achieving the purpose of eliminating the bubbles.
[0024] During actual use, the water-based anti-counterfeiting ink raw material is fed into the ink raw material feeding box 3 through the feed port 4, and the drive motor 5 is started. The drive motor 5 controls the rotation of the main shaft 6. Under the connection and drive of the first drive connection group 72 and the second drive connection group 82, the first mixing rod 61 and the second mixing rod 81 are driven to rotate, which can stir the water-based anti-counterfeiting ink raw material to generate centrifugal force, thereby removing bubbles, and at the same time drive the rotation of multiple rotating plates 71, thereby transporting the water-based anti-counterfeiting ink raw material to the interior of the mixing box 1. A relatively closed structure for feeding is formed between the rotating plate 71 and the cylindrical cavity 31, reducing the entry of air from the top opening of the mixing device. At the same time, the air in the mixing box 1 is sucked through the vacuum suction port 91 through the start-up control of the vacuum pump 9, thereby achieving the purpose of eliminating bubbles, thereby avoiding the subsequent water-based anti-counterfeiting ink printed patterns from being missing and producing defective products.
