[0023] When the preparation and grinding equipment of screen printing ink stirs the raw materials for preparing the ink, the dual-axis motor drives the first rotating rod to rotate at high speed, and the first rotating rod drives the stirring rod 1 to rotate at high speed, and at the same time, the rotation direction of the stirring rod 1 is the direction of the blade 3 facing the raw materials. Then, when the stirring rod 1 rotates at high speed, several groups of blades 3 in the knife groove 2 cut through the surfaces of various raw materials, thereby cutting the pigments that are bonded into large particles, so that the pigments are cut into small pieces again, thereby greatly improving the mixing uniformity of the various raw materials after stirring; at the same time, a quick disassembly and assembly component is provided between the knife groove 2 and the blade 3, so that when the sharpness of a group of blades 3 decreases too seriously, the group of blades 3 can be easily replaced.

[0024] Embodiment 2: On the basis of embodiment 1, in order to realize the replacement of the blade 3, a quick disassembly assembly is provided between the blade 3 and the knife groove 2, and the quick disassembly assembly comprises: a limit plate 6, the limit plate 6 is a rectangular plate structure, one end of the limit plate 6 is movably inserted in the limit groove 4, the limit groove 4 is arranged on the inner wall of the knife groove 2, the other end of the limit plate 6 is movably inserted in the limit plate mounting groove 5, the limit plate mounting groove 5 is arranged on the surface of the blade 3, and the limit plate 6 is provided on the surface of each group of blades 3 Two groups, the two groups of limit plates 6 are symmetrically distributed about the blade 3, the limit groove 4 and the limit plate mounting groove 5 are both rectangular groove structures, a spring 7 is fixed between one end of the limit plate 6 extending into the limit plate mounting groove 5 and the inner wall of the limit plate mounting groove 5, a lever window 8 is opened at one end of the blade 3, the lever window 8 is connected with the limit plate mounting groove 5, a lever 9 is slidably connected in the lever window 8, the lever 9 is a rectangular plate structure, one end of the lever 9 is fixed on the surface of the limit plate 6, and the other end of the lever 9 extends out from the lever window 8.

[0025] When it is necessary to replace the blade 3, the two groups of levers 9 on the surface of the group of blades 3 are simultaneously pushed in the direction of approaching each other, and the lever 9 slides in the lever window 8 to drive the limiting plate 6 to move in the same direction as the lever 9, so that the limiting plate 6 withdraws from the limiting groove 4 and is completely retracted into the limiting plate mounting groove 5, and then the lever 9 can be pulled outward to pull the group of blades 3 out of the knife groove 2, and the old blade 3 is disassembled; thereafter, the two groups of levers 9 are simultaneously pushed in the direction of approaching each other for the new blade 3, and the lever 9 drives the limiting plate 6 to be completely retracted into the limiting plate mounting groove 5 again, so that the spring 7 is compressed, and then the blade 3 is placed in the knife groove 2, and the two groups of limiting plate mounting grooves 5 on the surface of the blade 3 are aligned with the two groups of limiting grooves 4 at the upper and lower ends of the blade 3, and then the lever 9 is slowly released, so that the spring 7 can push one end of the two groups of limiting plates 6 into the limiting groove 4 under its own elastic action, and the blade 3 is replaced.

[0026] Embodiment 3: On the basis of Embodiment 2, in order to prevent the raw material from entering the limit plate mounting groove 5 from the lever window 8, a plug 10 is movably inserted in the lever window 8. The plug 10 is in a rectangular block structure. A plurality of groups of elastic protrusions 12 are fixed on the end surface of the plug 10 that contacts the inner wall of the lever window 8, and a pull rod 11 is fixed to one end of the plug 10 that extends out of the lever window 8.

At the same time, a large number of elastic protrusions 12 fixed on the surface of the plug 10 are compressed by the inner wall of the lever window 8 and the plug 10 after the plug 10 is inserted into the lever window 8, thereby generating a great friction force between the elastic protrusion 12 and the inner wall of the lever window 8, which can prevent the plug 10 from being thrown out of the lever window 8 when the knife groove 2 drives the blade 3 to rotate at a high speed. When the blade 3 needs to be replaced, the plug 10 can be pulled out of the lever window 8 by pinching the pull rod 11 and pulling it outward.

[0028] In actual use, the dual-axis motor drives the first rotating rod to rotate at a high speed, and the first rotating rod drives the stirring rod 1 to rotate at a high speed. At the same time, the rotation direction of the stirring rod 1 is the direction of the blade 3 facing the raw material. When the stirring rod 1 rotates at a high speed, several groups of blades 3 in the knife groove 2 cut through the surface of various raw materials, thereby cutting the pigments that are bonded into large particles, so that the pigments are cut into small pieces again, thereby greatly improving the mixing uniformity of the various raw materials after stirring; at the same time, a quick disassembly and assembly component is set between the knife groove 2 and the blade 3, so as to achieve a certain group of blades 3.

When the two groups of levers 9 are moved, the lever 9 drives the limit plate 6 to retract completely into the limit plate mounting groove 5 again, so that the spring 7 is compressed, and then the blade 3 is placed in the knife groove 2, and the two groups of limit plate mounting grooves 5 on the surface of the blade 3 are aligned with the two groups of limit grooves 4 at the upper and lower ends of the blade 3, and then the lever 9 is slowly released, so that the spring 7 can push one end of the two groups of limit plates 6 into the limit groove 4 under its own elastic action, and the blade 3 is replaced; when the blade 3 does not need to be replaced, the plug 10 is inserted into the lever window 8, and the plug 10 blocks the lever window 8 It plays the role of preventing the raw material from entering the limit plate mounting groove 5 through the lever window 8; at the same time, a large number of elastic protrusions 12 fixed on the surface of the plug block 10 are compressed by the inner wall of the lever window 8 and the plug block 10 after the plug block 10 is inserted into the lever window 8, thereby generating a great friction force between the elastic protrusions 12 and the inner wall of the lever window 8, which can prevent the plug block 10 from being thrown out of the lever window 8 when the knife groove 2 drives the blade 3 to rotate at high speed; when the blade 3 needs to be replaced, the plug block 10 can be pulled out of the lever window 8 by pinching the pull rod 11 and pulling it outward.
