[0021] 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.

[0022] Reference Figure 1-Figure 3As shown, the utility model provides a multi-stage particle classification device for pigments, including a box body 1, wherein a first filter cartridge 4, a second filter cartridge 5 and a third filter cartridge 6 are sequentially arranged inside the box body 1 from top to bottom, the first filter cartridge 4, the second filter cartridge 5 and the third filter cartridge 6 are used for screening pigment particles, and a guide mechanism 3 is arranged on the left and right sides of the box body 1, the guide mechanism 3 is used for guiding the screened pigment particles, and the pigment particles can be screened step by step through the cooperation of the set guide mechanism 3 and the first filter cartridge 4, the second filter cartridge 5 and the third filter cartridge 6, so that the pigment particles can be quickly screened and collected without repeated screening, thereby improving screening efficiency and saving operation time.

[0023] In a further embodiment, referring to Figure 2-Figure 4 The inner diameters of the first filter cartridge 4 and the third filter cartridge 6 gradually increase from left to right, and the inner diameter of the second filter cartridge 5 gradually decreases from left to right.

[0024] In this embodiment, since the inner diameters of the first filter cartridge 4 and the third filter cartridge 6 gradually increase from left to right, and the inner diameter of the second filter cartridge 5 gradually decreases from left to right, when the first filter cartridge 4, the second filter cartridge 5 and the third filter cartridge 6 are rotated, the pigment particles inside the first filter cartridge 4 and the third filter cartridge 6 can automatically move from left to right, while the pigment particles inside the second filter cartridge 5 automatically move from right to left, thereby facilitating the automatic grading and screening of the pigment particles.

[0025] In a further embodiment, referring to Figure 2 Filter holes 9 are provided on the side walls of the first filter cartridge 4 , the second filter cartridge 5 , and the third filter cartridge 6 , and the diameters of the filter holes 9 in the first filter cartridge 4 , the second filter cartridge 5 , and the third filter cartridge 6 become larger in sequence.

[0026] In this embodiment, the pore sizes of the filter holes 9 in the first filter cartridge 4 , the second filter cartridge 5 , and the third filter cartridge 6 are successively enlarged so that the pigment particles can fall from different filter holes 9 , thereby achieving a screening effect.

[0027] In a further embodiment, referring to Figure 2-Figure 3The guide mechanism 3 includes a first fixed plate 31 and a second fixed plate 32. The first fixed plate 31 is fixedly connected to the left end of the box body 1, and the second fixed plate 32 is fixedly connected to the right end of the box body 1. The left end surface of the first fixed plate 31 is provided with a first material guide groove 311 and a third material guide groove 312. The first material guide groove 311 is located at the upper end of the third material guide groove 312. The right end surface of the second fixed plate 32 is provided with a second material guide groove 321. The first filter cartridge 4, the second filter cartridge 5 and the third filter cartridge 6 are rotatably connected between the first fixed plate 31 and the second fixed plate 32. The right side of the first filter cartridge 4 is connected to the right side of the second filter cartridge 5 through the second material guide groove 321, and the left side of the second filter cartridge 5 is connected to the left side of the third filter cartridge 6 through the third material guide groove 312.

[0028] In this embodiment, by moving the pigment particles in the first filter barrel 4 to the right, the pigment particles will reach the inside of the second filter barrel 5 from the second material guide groove 321. At the same time, the pigment particles in the second filter barrel 5 move to the left, so that the pigment particles will reach the third filter barrel 6 through the third material guide groove 312, thereby facilitating the guiding of the pigment particles.

[0029] In a further embodiment, referring to Figure 2-Figure 3 A first guide plate 33, a second guide plate 34, a third guide plate 35 and a fourth guide plate 36 are fixedly connected between the first fixed plate 31 and the second fixed plate 32 from top to bottom in sequence, the first guide plate 33 is located above the first filter cartridge 4, the second guide plate 34 is located between the first filter cartridge 4 and the second filter cartridge 5, the third guide plate 35 is located between the second filter cartridge 5 and the third filter cartridge 6, and the fourth guide plate 36 is located below the third filter cartridge 6. A feed port 11 is provided at the upper end of the box body 1, and the feed port 11 is connected to the first guide groove 311. A second discharge port 13 is provided at the front end of the box body 1. The second discharge port 13 is provided in three groups and is respectively located in front of the second guide plate 34, the third guide plate 35 and the fourth guide plate 36. A first discharge port 12 is provided at the right end of the box body 1 and is located on the right side of the third filter cartridge 6.

[0030] In this embodiment, the unscreened pigment particles are input from the feed port 11, and reach the first filter cartridge 4 in cooperation with the first guide plate 33 and the first guide groove 311, and then the pigment particles are screened. The screened particles fall into the second guide plate 34, and the pigment particles screened by the second filter cartridge 5 fall into the third guide plate 35, and the pigment particles screened by the third filter cartridge 6 fall into the fourth guide plate 36, and the unscreened pigment particles are discharged from the first discharge port 12.

[0031] In a further embodiment, referring to Figure 1-Figure 2A rotating shaft 7 is rotatably connected inside the box body 1. Three groups of rotating shafts 7 are arranged. A connecting rod 71 is fixedly connected to the side wall of each group of rotating shafts 7. The inner walls of the first filter cartridge 4, the second filter cartridge 5 and the third filter cartridge 6 are fixedly connected to the end of the connecting rod 71 away from the rotating shaft 7. A motor 2 is fixedly connected to the right end of the box body 1. The output shaft end of the motor 2 is fixedly connected to the left end of the rotating shaft 7. The rotating shafts 7 are connected through a pulley group 8 for transmission.

[0032] In this embodiment, the rotating shaft 7 is driven to rotate by starting the motor 2, and the rotating shafts 7 are connected by a pulley group 8, thereby driving the three groups of rotating shafts 7 to rotate simultaneously. The rotation of the rotating shaft 7 drives the first filter cylinder 4, the second filter cylinder 5 and the third filter cylinder 6 to rotate through the connecting rod 71, thereby providing power for the grading and screening of pigment particles.

[0033] The working principle of the utility model is as follows: the rotating shaft 7 is driven to rotate by starting the motor 2, and the rotating shafts 7 are connected by the pulley group 8, thereby driving the three groups of rotating shafts 7 to rotate simultaneously, and the rotating shaft 7 rotates through the connecting rod 71 to simultaneously drive the first filter cylinder 4, the second filter cylinder 5 and the third filter cylinder 6 to rotate, and then the unscreened pigment particles are poured from the feed port 11 to the top of the first guide plate 33, and since the first guide plate 33 is connected to the first guide groove 311, the pigment particles reach the first filter cylinder 4 through the first guide groove 311, and the pigment particles are initially screened by the first filter cylinder 4, and the screened pigment particles are directly guided out of the inside of the box 1 by the second guide plate 34, and the larger pigment particles are moved to the second guide groove 321 by the rotation of the first filter cylinder 4, so that the pigment particles reach the second filter cylinder 5 for secondary screening, and the same steps are used to achieve rapid screening of the pigment particles, and finally the oversized pigment particles are discharged from the first discharge port 12 on the right side of the third filter cylinder 6, which solves the problem that the existing pigment particles are relatively cumbersome in the screening process.
