Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1, Reference Figures 1 to 19A raw material grinding device based on latex paint production is shown, comprising a cone crusher 2, an outer cover 7 is arranged inside the cone crusher 2, and a support frame 6 connected to the inner wall of the cone crusher 2 is arranged on the outer surface of the outer cover 7, a first toothed disc 10, a second toothed disc 11 and a bevel gear rod 9 are arranged inside the outer cover 7, and the bevel gear rod 9 is meshed with the first toothed disc 10 and the second toothed disc 11, one end of the bevel gear rod 9 passes through the outer cover 7 and the cone crusher 2 and is fixedly installed with a pulley 1, the first toothed disc 10 is used to provide power for the cone crusher 2, the second toothed disc 11 is installed inside the outer cover 7 through a bearing, and a shaft 8 is arranged at the bottom of the second toothed disc 11; A grinding mechanism 3 for grinding latex paint raw materials is arranged at the bottom of the cone crusher 2, a plate mold mechanism 5 for crushing and grinding raw material particles is arranged at the upper part of the inner cavity of the grinding mechanism 3, and a fine grinding mechanism 4 for finely grinding raw material powder is arranged inside the grinding mechanism 3 and below the plate mold mechanism 5; A grinding cone 12 is fixedly mounted on the lower end of the outer cover 7, and one end of the shaft 8 passes through the grinding cone 12 without contact. The disc mold mechanism 5 includes a grinding component 51 that cooperates with the grinding cone 12 to crush and grind the raw material particles, and a powder component 52 that cooperates with the grinding component 51 to further crush the raw material particles.

[0024] It is worth noting that when the latex paint raw material is crushed, the pulley 1 drives the first toothed disc 10 and the second toothed disc 11 to rotate through the bevel gear rod 9, and the first toothed disc 10 provides power for the cone crusher 2 to crush the raw material into particles, and the set cone crusher 2 belongs to the existing technology, and the crushed raw material falls into the inside of the grinding assembly 51, and the rotation of the second toothed disc 11 drives the shaft 8 to rotate, and the shaft 8 is located in the grinding assembly 51 to provide power to grind the granular latex paint raw material; After being ground by the grinding component 51, the latex paint raw materials will fall into the powder component 52, and the powder component 52 will finely grind the granular raw materials. The raw materials ground by the powder component 52 will fall onto the surface of the fine grinding mechanism 4 and be ground again in the form of rollers; the raw materials ground by the fine grinding mechanism 4 will be discharged after being ground in the form of impact by the grinding mechanism 3, and the cone crusher 2 will crush the bulk raw materials into granules to prepare for the subsequent grinding steps, ensuring the initial refinement of the raw materials and reducing the wear of the bulk raw materials on subsequent equipment. The grinding component 51 and the powder component 52 respectively perform preliminary grinding and fine grinding on the granular raw materials, ensuring that the materials can be fully processed at each stage. The roller grinding of the fine grinding mechanism 4 further improves the grinding accuracy, making the particle size of the final product more uniform and fine, and the multi-stage grinding ensures that the particle size of the final product is uniform and fine, thereby improving the coating performance and appearance quality of the latex paint.

[0025] Embodiment 2: Based on the disc mold mechanism 5 proposed in Embodiment 1, this embodiment provides a further technical solution for the grinding component 51 and the powder component 52.

[0026] The grinding assembly 51 includes a grinding disc 511, an annular groove 514 is provided in the middle of the outer surface of the grinding disc 511, the inner cavity of the grinding disc 511 is funnel-shaped, and the inner wall of the grinding disc 511 is provided with a plurality of grinding grooves 512 distributed in a circular array, and the grinding cone 12 is located inside the grinding disc 511 to cooperate with the grinding grooves 512 to crush the raw material particles.

[0027] It is worth mentioning that after the raw material is crushed by the cone crusher 2, it first falls into the inside of the grinding disc 511, and then falls between the grinding cone 12 and the grinding groove 512. The rotation of the shaft 8 will drive the grinding disc 511 to rotate, and the raw material is crushed and ground through the rotation of the grinding cone 12 and the grinding groove 512. Because the grinding cone 12 is in the shape of a cone bucket and cooperates with the grinding groove 512, it can quickly crush the raw material particles.

[0028] A plurality of leakage holes 513 distributed in a circular array are provided in the middle of the bottom wall of the grinding disc 511. The grinding disc 511 is fixedly mounted on the outer surface of the shaft 8. A grinding ball hoop 515 is provided at the bottom of the grinding disc 511. The grinding disc 511 is limited inside the outer cylinder 34 by the annular groove 514 and the rib ring 35.

[0029] The crushed raw material particles will fall into the leak hole 513, and because the cavity inside the grinding disc 511 is funnel-shaped, the raw material particles will continue to fall between the grinding groove 512 and the grinding cone 12 to be crushed.

[0030] The powder assembly 52 includes a support frame 522, which is fixedly installed inside the outer cylinder 34. A second chassis 521 is arranged at the upper end of the support frame 522. A ball grinding groove 524 is opened on the outer surface of the second chassis 521. A plurality of grinding balls 523 are arranged inside the ball grinding groove 524 and the grinding ball hoop 515, and the grinding balls 523 are in contact with the inner wall of the grinding ball hoop 515. One end of the shaft 8 passes through the second chassis 521 and the support frame 522.

[0031] The material passing through the leak hole 513 will fall between the second chassis 521 and the grinding disc 511. The second chassis 521 and the grinding disc 511 are combined in the form of a grinding disc to grind the raw material again. The surfaces of the second chassis 521 and the grinding disc 511 are provided with grinding lines, thereby improving the grinding efficiency of the raw material. The second chassis 521 is fixed inside the grinding mechanism 3 through the support frame 522, so that the raw material ground by the second chassis 521 and the grinding disc 511 falls from the surroundings of the second chassis 521. The rotation of the grinding disc 511 will also drive the grinding ball hoop 515 to rotate. There is a gap between the grinding ball hoop 515 and the second chassis 521, so that the raw material powder falling from the periphery of the second chassis 521 enters the ball track grinding groove 524. When the grinding ball hoop 515 rotates, it will also drive the grinding balls 523 to roll. The grinding balls 523 roll and crush the raw materials that fall into the ball track grinding groove 524. The raw material powder crushed by the grinding balls 523 will fall to the upper part of the fine grinding mechanism 4.

[0032] The second chassis 521 and the grinding disc 511 are combined into a grinding disc form, and grinding lines are provided on the surfaces of the second chassis 521 and the grinding disc 511, thereby increasing the grinding area and friction force and improving the grinding efficiency.

[0033] The rotation of the grinding disc 511 drives the grinding ball hoop 515 to rotate. A gap is provided between the grinding ball hoop 515 and the second chassis 521 to ensure that the material can smoothly enter the ball grinding groove 524. The grinding balls 523 roll in the ball grinding groove 524 to further grind the raw material powder that falls into the ball grinding groove. The rolling and grinding of the grinding balls 523 can grind the material more finely to make the particle size uniform and small. The rotation of the grinding disc 511 drives the rotation of the grinding ball hoop 515 to realize a continuous grinding process.

[0034] Embodiment 3: Based on the fine grinding mechanism 4 and the grinding mechanism 3 proposed in Embodiment 1, this embodiment provides a further technical solution for the fine grinding mechanism 4 and the grinding mechanism 3.

[0035] The fine grinding mechanism 4 includes a mounting block 46 fixedly mounted on the outer surface of the shaft 8, and the outer surface of the mounting block 46 is provided with a plurality of support rods 47 distributed in a circular array, and a support ring 41 is commonly provided at one end of the plurality of support rods 47, and a cone roller 42 is rotatably mounted on the outer surface of the support rod 47, and the outer surfaces of the plurality of cone rollers 42 are provided with a grinding groove 43.

[0036] The fine grinding mechanism 4 also includes a fixed plate 45 , the upper end of which is provided with a grinding rib 44 , which meshes with the grinding groove 43 , and a plurality of cone rollers 42 are located at the lower part of the powder assembly 52 , and a hole 49 is opened in the middle of the upper end of the fixed plate 45 .

[0037] The fixed plate 45 is located at the upper end of the conical grinding plate 36 , and the upper and lower ends of the fixed plate 45 are both funnel-shaped.

[0038] It is worth noting that when the shaft 8 rotates, it will also drive the mounting block 46 to rotate, and the mounting block 46 will drive the support rod 47 to rotate, and the support rod 47 will push the cone roller 42 to rotate. The cone roller 42 rolls on the surface of the fixed plate 45, and the raw material powder that falls off after being ground by the grinding balls 523 will fall into the upper part of the fixed plate 45. Due to the setting of the grinding ball hoop 515 and the ball grinding groove 524, the raw material powder falls downward along the inner wall of the outer cylinder 34, and the fallen raw material powder falls around the upper end of the fixed plate 45. After the cone roller 42 rotates, the raw material powder is further crushed at the grinding groove 43 and the grinding rib 44. With the rotation and crushing of the cone roller 42 and the cooperation with the funnel shape at the upper end of the fixed plate 45, the fallen raw material powder gradually moves to the middle of the fixed plate 45, and finally falls into the interior of the grinding mechanism 3 through the hole 49.

[0039] Among them, the rotation of the shaft 8 is transmitted to the cone roller 42 through the mounting block 46 and the support rod 47, ensuring the effective transmission of power. The cone roller 42 rolls on the surface of the fixed plate 45 to perform preliminary grinding of the raw material powder, ensuring the preliminary refinement of the material. The design of the grinding ball hoop 515 and the ball grinding groove 524 allows the raw material powder to fall downward along the inner wall of the outer cylinder 34, ensuring the uniform distribution of the material and avoiding local accumulation. The rotation of the cone roller 42 allows the raw material powder to be further ground at the grinding groove 43 and the grinding rib 44, ensuring that the particle size of the material is more uniform and fine.

[0040] The grinding mechanism 3 includes an outer cylinder 34 installed at the lower end of the cone crusher 2, a rib ring 35 is provided on the upper part of the inner wall of the outer cylinder 34, a first chassis 33 is provided at the lower end of the outer cylinder 34, a discharge pipe 31 and a push rod 32 are provided at the lower end of the first chassis 33, a lubrication sleeve 312 is provided inside the first chassis 33, a support shaft 311 is provided inside the lubrication sleeve 312 and is rotatably and slidably installed inside the lubrication sleeve 312, and a dust cover 38 is provided on the outer surface of the support shaft 311.

[0041] A conical grinding disc 36 is disposed at the upper end of the supporting shaft 311, and a limit hole is provided through the middle of the conical grinding disc 36, and a connecting rod 39 is slidably installed in the limit hole. The connecting rod 39 is fixedly mounted on the lower end of the shaft rod 8 , and the lower end of the supporting shaft rod 311 is rotatably connected to the top shaft inside the push rod 32 .

[0042] It is worth noting that when the raw material powder falls onto the surface of the conical grinding disc 36 through the hole 49, because the upper end of the conical grinding disc 36 and the lower end of the fixed disc 45 are both in a conical bucket shape that fits together, the shaft rod 8 rotates to drive the connecting rod 39 to rotate, which will also drive the conical grinding disc 36 to rotate, and the set push rod 32 continuously pushes the conical grinding disc 36 up and down through the support shaft 311, and the set limit hole allows the conical grinding disc 36 to slide up and down on the outer surface of the connecting rod 39, and the push rod 32 belongs to the prior art and is connected to the disc shaft and the support shaft 311 through an electric push rod, so that the support shaft 311 can also push the conical grinding disc 36 up and down when rotating, so that the conical grinding disc 36 can rotate and squeeze the raw material powder falling from the hole 49; The raw material powder is finely ground by extrusion and rotation grinding, so that the raw material powder can remain suspended in the latex paint to improve the quality of the latex paint.

[0043] Among them, the rotation of the shaft rod 8 drives the connecting rod 39 to rotate, and then drives the conical grinding disc 36 to rotate, ensuring the uniform distribution and preliminary grinding of the material on the conical grinding disc. The push rod 32 continuously pushes the conical grinding disc 36 up and down through the supporting shaft rod 311, so that the conical grinding disc 36 moves up and down while rotating, increasing the grinding contact surface, extruding and rotating the raw material powder to grind it, making the particle size of the material more uniform and fine, and improving the grinding accuracy.

[0044] It is worth noting that the grinding disc 511, the cone roller 42 and the cone grinding disc 36 are respectively responsible for grinding at different stages, from preliminary crushing to fine grinding, ensuring that the material can be fully processed at each stage, and the rotation of the grinding disc 511 drives the rotation of the grinding ball hoop 515 to realize a continuous grinding process, the rolling and rolling of the grinding balls 523 in the ball track grinding groove 524, and the rolling of the cone roller 42 in the grinding groove 43 and the grinding rib 44 ensure that the particle size of the material is more uniform and fine, and the rotation and up and down movement of the cone grinding disc 36 are combined to extrude and rotate the raw material powder to further improve the grinding accuracy and ensure the uniform particle size of the final product.

[0045] The invention also provides a grinding method for a raw material grinding device based on latex paint production, and the specific grinding method is as follows: S1. When the latex paint raw material is crushed, the pulley 1 drives the first toothed disc 10 and the second toothed disc 11 to rotate through the bevel gear rod 9. The first toothed disc 10 provides power for the cone crusher 2 to crush the raw material into particles. The crushed raw material falls into the inside of the grinding assembly 51. The rotation of the second toothed disc 11 drives the shaft 8 to rotate. The shaft 8 is located in the grinding assembly 51 to provide power to grind the granular latex paint raw material. S2, the latex paint raw material will fall into the powder component 52 after being ground by the grinding component 51, and the powder component 52 will finely grind the granular raw material, and the raw material ground by the powder component 52 will fall onto the surface of the fine grinding mechanism 4 and be ground again by the roller form; S3, the raw materials ground by the fine grinding mechanism 4 will be discharged after being ground in the form of impact by the grinding mechanism 3. The cone crusher 2 will crush the bulk raw materials into granules to prepare for the subsequent grinding steps, ensuring the initial refinement of the raw materials and reducing the wear of the bulk raw materials on the subsequent equipment. The grinding component 51 and the powder component 52 respectively perform preliminary grinding and fine grinding on the granular raw materials to ensure that the materials can be fully processed at each stage. The roller grinding of the fine grinding mechanism 4 further improves the grinding accuracy, making the particle size of the final product more uniform and fine. The multi-stage grinding ensures that the particle size of the final product is uniform and fine, and improves the coating performance and appearance quality of the latex paint.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
