[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an ink filtering device for a vacuum plugging machine, comprising an ink hopper 1 installed on the vacuum plugging machine for adding ink. The ink hopper 1 has a notch on one side, and an L-shaped plate 2 is installed inside the notch. The notch is sealed by the vertical end of the L-shaped plate 2. The horizontal end of the L-shaped plate 2 is located inside the ink hopper 1 and has an installation port. A frame 8 is installed in the installation port, and a filter screen 9 for filtering ink is installed inside the frame 8. A vibrator 3 is installed on the outer surface of the L-shaped plate 2, and a motor 5 is installed on one side of the ink hopper 1 to drive the L-shaped plate 2 to rotate. The motor is a brake motor, which allows the L-shaped plate to be positioned after rotation.

[0022] In this embodiment, a fixing plate 6 is installed on one side of the ink fountain 1. One end of the fixing plate 6 is provided with a screw hole, and a hand-tightening bolt 7 is threaded into the screw hole. One end of the hand-tightening bolt 7 is set to abut against the outer side of the L-shaped plate 2. The hand-tightening bolt can position the outer side of the L-shaped plate, thus preventing the L-shaped plate from automatically opening outward.

[0023] In this embodiment, shaft holes are provided on both sides of the notch. The shaft hole on one side is set through the ink fountain 1. The rotating shaft of the motor 5 passes through the shaft hole on one side and is fixedly connected to the L-shaped plate 2. A shaft rod 11 is installed on the side of the L-shaped plate 2 away from the motor 5. The shaft rod 11 is inserted into the shaft hole on the other side.

[0024] In this embodiment, an inclined surface is provided on the bottom surface of the notch, and a rubber strip 4 is installed on the inclined surface. The rubber strip 4 is set to abut against the L-shaped plate 2. The rubber strip can seal the gap between the notch and the L-shaped plate, preventing the ink from being exposed. Rubber strips are also installed at both ends of the L-shaped plate in the width direction to further ensure its sealing performance.

[0025] In this embodiment, the mounting opening is provided with grooves on both sides, and the frame 8 protrudes on both sides to form slide bars 10. The slide bars 10 are slidably disposed in the grooves, and one end of the frame 8 is in contact with the inner wall of the ink fountain 1. The frame can be positioned by the grooves and slide bars, thus preventing the frame from falling directly from the mounting opening.

[0026] In this embodiment, the length and width of one lateral end of the L-shaped plate 2 match the length and width of the inner cavity of the ink hopper 1, so that the outer side of the L-shaped plate can contact the inner side of the ink hopper to ensure its sealing.

[0027] When in use, the ink can be poured directly into the ink hopper and come into contact with the filter screen. The ink can be filtered through the filter screen. During the filtration process, the vibrator can be activated. The vibrator generates vibration energy that acts on the L-shaped plate and the frame, causing the filter screen to vibrate. Through the vibration energy, the ink can quickly pass through the filter holes to achieve a rapid filtration effect.

[0028] After filtration is complete, rotate the hand-tightening bolt outward to move the bolt rod away from the outside of the L-shaped plate. At this time, the motor can be started. The motor starts and drives the L-shaped plate to rotate around the shaft. This rotates the previously vertical end of the L-shaped plate to the outside, while the end with the frame is placed in the notch. This allows the impurities on the filter screen to be placed outward, and the vibrator can quickly shake them off, making it easy to clean.

[0029] When the motor drives the L-shaped plate to rotate outward again, the L-shaped plate can squeeze the rubber strip, causing one end of the frame to be completely removed from the ink fountain. At this time, the frame can be taken out directly through the opening at one end of the mounting port, and the new filter screen can be directly inserted into the mounting port and slidably connected with the slide groove, making it convenient to replace.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
