[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-6 This embodiment provides an ink feed box for a conical sand mill, including a box body 1. The top of the box body 1 is provided with a feed port 2 connected thereto, and a feed pump 3 is provided near the bottom of the box body 1. A filter screen 4 is provided inside the box body 1. A stirring mechanism 5 is provided on the box body 1 to prevent ink sedimentation and filter screen 4 from clogging. The stirring mechanism 5 includes a motor unit 51 provided at the top of the box body 1. A stirring blade 53 located inside the box body 1 is provided on the output end of the motor unit 51 through a connecting shaft 52.

[0025] In this invention, when the feeding box is used, the ink enters the box body 1 through the feed port 2. When the ink enters, impurities in the ink are filtered through the filter screen 4 inside the box body 1, ensuring that only fine ink that meets the requirements can enter the sand mill for grinding, thereby improving the quality of the final ink product and avoiding printing defects caused by impurities. The filtered ink enters the box body 1 and is stored inside the box body 1. The motor unit 51 starts and drives the stirring blade 53 on the connecting shaft 52 to stir the ink stored in the box body 1, preventing pigment sedimentation and stratification, and ensuring the uniformity of the ink. When it is necessary to send the ink to the sand mill, the feed pump 3 can transport the ink in the box body 1.

[0026] Specifically, such as Figures 2-4As shown, a cleaning component 54 is provided on the connecting shaft 52. The cleaning component 54 includes a mounting base 541 fixed on the connecting shaft 52. A cleaning brush 543 is provided on the mounting base 541 via a fixing plate 542, which abuts against the surface of the filter screen 4. A connecting bracket 544 is provided on the mounting base 541 to cooperate with the fixing plate 542, and a fixing bolt 545 is provided on the connecting bracket 544 to pass through the fixing screw hole 546.

[0027] When the motor unit 51 drives the connecting shaft 52 to rotate, the connecting shaft 52 drives the fixing plate 542 on the mounting base 541 to rotate, thereby causing the cleaning brush 543 on the fixing plate 542 to rotate on the surface of the filter screen 4. The rotating cleaning brush 543 cleans the surface of the filter screen 4, scraping or brushing off the impurities on the filter screen 4, keeping the filter screen 4 in a good permeable state, ensuring that the ink can pass through the filter screen 4 smoothly. This helps to maintain a stable ink feed and stable operation of the sand mill, improving production efficiency and product quality stability. When it is necessary to clean or replace the cleaning brush 543, the fixing bolt 545 on the connecting bracket 544 is unscrewed, so that the fixing bolt 545 is disengaged from the fixing screw hole 546 of the fixing plate 542. Then, the fixing plate 542 and the cleaning brush 543 can be removed from the mounting base 541 for cleaning and replacement.

[0028] Specifically, such as Figure 2 and Figure 5 As shown, the filter screen 4 is detachably installed in the housing 1 via the mounting bracket 41. The mounting bracket 41 is provided with a positioning rod 42 that passes through the filter screen 4, and a spring 43 is sleeved on the positioning rod 42 between the mounting bracket 41 and the filter screen 4. The top of the positioning rod 42 is provided with a mounting nut 45 that abuts against the surface of the filter screen 4 via a threaded end 44.

[0029] During the installation of filter screen 4, the positioning holes on filter screen 4 are aligned with the positioning rod 42 of mounting bracket 41, and then the mounting nut 45 is screwed onto the threaded end 44 at the top of the positioning rod 42. This facilitates the installation and removal of filter screen 4 within the housing 1. A spring 43 is sleeved on the positioning rod 42 between filter screen 4 and mounting bracket 41. The spring 43 allows filter screen 4 to move up and down elastically on mounting bracket 41. When cleaning component 54 cleans the surface of filter screen 4, it can prevent excessive pressure from the cleaning component 54 from damaging filter screen 4, and it can also allow filter screen 4 to move elastically to more easily remove impurities clogging the filter holes of filter screen 4, thereby improving cleaning efficiency.

[0030] Specifically, such as Figure 1 and Figure 6 As shown, a heating component 6 is provided on the side of the box body 1. The heating component 6 includes a fixing seat 61 that is detachably installed on the box body 1. Several electric heating tubes 62 are provided inside the fixing seat 61 through a terminal block 63.

[0031] The terminal block 63 is connected to the power supply, which allows the heating element 62 in the fixed base 61 to heat the ink in the box 1. The viscosity of the ink changes with temperature. Under normal circumstances, the ink viscosity decreases as the temperature rises. The heating component 6 can raise the ink temperature to reduce its viscosity to a suitable range, thereby enhancing the ink's fluidity. This facilitates the stirring and conveying of the ink in the feed box and the grinding operation after entering the sand mill, avoiding problems such as difficulty in stirring and poor feeding caused by excessive ink viscosity.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
