Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As described in the background section, the filtration of ink before stirring is generally achieved by combining a vibrator with a filter screen to filter impurities in the ink. However, impurities will remain on the filter screen, and the filter screen needs to be removed and cleaned periodically. This method is time-consuming and laborious, reducing work efficiency.

[0017] To solve this technical problem, the present invention provides a filter device for ink stirring, which is applied to provide a filter device for ink stirring that can easily clean impurities from the filter device.

[0018] Specifically, refer to Figures 1-4 A filtering device for ink mixing includes a tank 2, with an inlet 6 on the top of the tank 2 and an outlet 8 on the outer wall of the tank 2. The filtering device for ink mixing also includes a filter plate 3 installed inside the tank 2 for filtering ink and a scraper 302 rotatably disposed along the height direction of the tank 2 and attached to the top surface of the filter plate 3. The filter plate 3 and the peripheral wall of the tank 2 are provided with two notches 301 for impurities to pass through. Guide seats 402 are installed on the peripheral wall of the tank 2 corresponding to the two notches 301, and the top of the guide seat 402 is provided with an outlet groove 407 on the same vertical line as the notch 301. An outlet hole 408 is opened on the outer wall of the tank 2 corresponding to the notch 301. A pusher block 406 for pushing out impurities is slidably installed in the outlet groove 407.

[0019] During the rotation of the scraper 302, the impurities remaining on the filter plate 3 can be scraped towards the notch 301. The impurities fall into the outlet groove 407 through the notch 301, and then the pusher 406 pushes the impurities towards the outlet hole 408 and out through the outlet hole 408, thereby achieving the effect of facilitating the cleaning of impurities on the filter plate 3. It is worth noting that the outlet groove 407 and the outlet hole 408 are connected to form an inverted T-shaped groove, which can accommodate the pusher 406. When the impurities fall from above, the pusher 406 pushes out the falling impurities. When the impurities fall on the top of the pusher 406, they can be scraped off by the inverted T-shaped groove wall when the pusher 406 retracts.

[0020] Reference Figure 3 and Figure 4 Preferably, the tank body 2 is provided with a pressing assembly that is connected to and drives the push block 406 to move. The pressing assembly includes a slide rod 403 connected to the push block 406 and one end of which passes through one side of the guide seat 402. A second protrusion 404 is fixedly provided on the end of the slide rod 403 away from the guide seat 402. A spring 405 sleeved on the slide rod 403 is provided between the guide seat 402 and the second protrusion 404. A ring frame 4 that is on the same horizontal line as the second protrusion 404 is rotatably provided in the tank body 2, and two first protrusions 401 that are respectively pressed and engaged with the two second protrusions 404 are fixedly provided along the circumference of the ring frame 4.

[0021] The rotation of the ring frame 4 causes the two first protrusions 401 to move in a ring motion to squeeze the second protrusion 404. The two second protrusions 404 compress the spring 405 with the help of the squeezing force of the two first protrusions 401, and drive the push block 406 to move through the slide rod 403 to push out the impurities in the discharge groove 407. When the first protrusion 401 moves away from the second protrusion 404, the spring 405 can release the elastic force compressed by the second protrusion 404, and drive the push block 406 to move and reset through the slide rod 403, thereby achieving the effect of reciprocating movement of the push block 406.

[0022] Reference Figure 2 and Figure 3 Preferably, a stirring shaft 501 fixedly connected to a ring frame 4 is rotatably installed inside the tank body 2, a stirring motor 5 connected to the stirring shaft 501 is installed on the top of the tank body 2, and stirring blades 502 for mixing ink are arranged in an array on the outer wall of the stirring shaft 501 in the height direction of the tank body 2.

[0023] Driven by the stirring motor 5, the stirring shaft 501 rotates, which in turn drives the stirring blades 502 to rotate, thus mixing the material in the tank 2. It is worth noting that the stirring blades 502 are arranged in an array, which can cover a larger stirring area and ensure that the material in different positions in the tank 2 is subjected to shear force and convection simultaneously, avoiding local dead corners and achieving a fast and uniform mixing effect, which is better suited for mixing high-viscosity inks.

[0024] Reference Figure 1 Preferably, a solenoid valve 801 is installed on the discharge port 8, and a control panel 7 connected to the solenoid valve 801 is installed on the tank body 2.

[0025] The settings on the control panel 7 make it easier for staff to open the solenoid valve 801, so as to better control the material discharged from the tank 2 through the discharge port 8.

[0026] The implementation principle of the ink mixing filter device in this application embodiment is as follows: First, the staff needs to accurately put the material into the tank 2 through the feed port 6. After the material enters the tank 2, it will first pass through the specially made filter plate 3 for fine filtration. During this process, various impurities are effectively blocked and retained on the filter plate 3.

[0027] Next, a command is issued via control panel 7 to start stirring motor 5. At this time, the output shaft of stirring motor 5 begins to rotate, driving the arrayed stirring blades 502 to rotate at high speed, thoroughly and evenly mixing the material in tank 2. After the mixing process is completed, the solenoid valve 801 is opened again via control panel 7. The thoroughly mixed material then flows out through the designated channel from outlet 8.

[0028] During the continuous rotation of the stirring shaft 501, it not only drives its attached scraper 302 to rotate synchronously, but the scraper 302 also performs a circular scraping treatment on the impurities accumulated on the filter plate 3. When the scraper 302 rotates to the position of the two notches 301 provided on the filter plate 3, the scraped impurities will fall into the outlet groove 407 located on the guide seat 402 through the two notches 301. At the same time, the ring frame 4 connected to the stirring shaft 501 will also rotate, thereby driving the two first protrusions 401 to make a stable circular motion. When the two first protrusions 401 contact the corresponding two second protrusions 404, pressure will be applied to move the second protrusions 404 and compress the spring 405 connected to them. Under the action of the second protrusions 404, through the transmission of the slide rod 403, the two push blocks 406 will slide smoothly in the outlet groove 407, pushing the impurities in the groove toward the outlet hole 408, and finally realizing the smooth discharge of impurities from the outlet hole 408. This enables the cleaning of impurities remaining on filter plate 3, completely avoiding the tedious steps of disassembling filter plate 3 in the traditional method, and significantly improving overall work efficiency.

[0029] To ensure effective collection of impurities, a collection bin can be placed below the outlet hole 408 beforehand. As the two first protrusions 401 gradually move away from the two second protrusions 404, the previously compressed spring 405 releases its stored elasticity, pushing the second protrusions 404 back to their original position. Simultaneously, the second protrusions 404, via the slide rod 403, cause the pusher block 406 to move and reset within the outlet groove 407. Ingeniously, if new impurities fall onto the surface of the pusher block 406 above the outlet groove 407 during the process of the pusher block 406 pushing out impurities and resetting, the pusher block 406, upon resetting, can use the vertical structure of the outlet groove 407 and the groove wall in contact with the top of the pusher block 406 to cleanly scrape the surface impurities back into the outlet groove 407, ensuring that no impurities remain on the pusher block 406.

[0030] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
