Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a continuous grinding equipment for preventing material accumulation in titanium dioxide processing. Background Technology

[0002] Titanium dioxide, also known as titanium dioxide, is an important white inorganic pigment. It is chemically stable, possesses a high refractive index, strong hiding power, and good whiteness. It is non-toxic and harmless, and is widely used in industries such as coatings, plastics, papermaking, and inks, significantly improving product appearance and performance.

[0003] Grinding titanium dioxide is a crucial step in improving its quality.

[0008] As a further embodiment of the present invention: the upper end cover of the fixed seat is provided with a top seat, and an extension plate is evenly arranged on the outer wall of the top seat, and a material distribution plate is provided on both sides of the extension plate.

[0009] As a further aspect of the present invention: the upper surface of the fixed grinding disc is a concave inclined surface, and a plurality of feeding grooves are uniformly provided through the bottom of the inclined surface. The feeding grooves are connected to the discharge bin, and a baffle ring protrusion extends upward from the top of the inclined surface.

[0010] As a further aspect of the present invention: the lower surface of the moving grinding disc is an outwardly convex inclined surface, and the bottom end of the moving grinding disc is adapted to the top end of the fixed grinding disc. A plurality of screening holes are provided through the moving grinding disc, and a feeding ring protrusion is provided extending upward from the outer edge of the moving grinding disc.

[0011] As a further embodiment of the present invention: a discharge port is provided on one side of the discharge bin, a feed port is provided at the upper end of the feed bin, one side of the inner wall of the feed bin is inclined, the feed port is located above the inclined wall, and a vibrating assembly is provided at the bottom of the feed bin.

[0012] As a further embodiment of the present invention: the vibrating material assembly includes a fixed frame, the fixed frame being fixedly disposed at the bottom of the feeding hopper, a support being disposed on the fixed frame, a vibrating material block being disposed inside the support, a connecting rod being fixedly disposed in the center of the vibrating material block, the connecting rod slidingly passing through the support and being connected to a contact plate, a return spring being disposed between the contact plate and the support, guide rods being fixedly disposed at both ends of the vibrating material block, the guide rods slidingly passing through the support, a servo motor being fixedly disposed on one side of the fixed frame, a cam being disposed at the output end of the servo motor, and the outer wall of the cam abutting against the contact plate.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-7 As shown, the present invention is a continuous grinding device for titanium dioxide processing to prevent material accumulation. It includes a base 1, a discharge chamber 2 fixedly mounted on the top of the base 1, a grinding chamber 3 fixedly mounted on the top of the discharge chamber 2, a feeding chamber 4 fixedly mounted on the top of the grinding chamber 3, a feeding motor 5 fixedly mounted on the upper end of the feeding chamber 4, a shaft 51 coaxially mounted to the output end of the feeding motor 5, a feeding auger 52 fixedly mounted on the outer wall of the shaft 51, a drive motor 6 fixedly mounted inside the base 1, a drive shaft 61 connected to the output end of the drive motor 6, a fixed seat 63 mounted on the top end of the drive shaft 61, a grinding assembly 7 mounted inside the grinding chamber 3, the grinding assembly 7 including a fixed grinding disc 71 and a moving grinding disc 72, the fixed grinding disc 71 being fixedly installed between the grinding chamber 3 and the discharge chamber 2, the moving grinding disc 72 being mounted on the outer wall of the fixed seat 63 and located above the fixed grinding disc 71, and an adjusting motor 74 for adjusting the distance between the fixed grinding disc 71 and the moving grinding disc 72 fixedly mounted on the upper end of the fixed seat 63.

[0027] Specifically, by setting up a discharge bin 2, a grinding bin 3, and a feed bin 4, during the grinding process, the feeding motor 5 drives the shaft 51 and the feeding auger 52 to rotate, so that the raw material enters the grinding bin 3 from the feed bin 4. At the same time, the drive motor 6 drives the moving grinding disc 72 to rotate through the fixed base 63, which, together with the fixed grinding disc 71, applies crushing and shearing action to the material to grind it into fine powder. During grinding, the gap between the moving grinding disc 72 and the fixed grinding disc 71 can be adjusted by adjusting the axial movement of the motor 74, thereby effectively controlling the degree of grinding and the output particle size of the powder, which is conducive to improving the grinding quality. The ground powder falls into the discharge bin 2 and is discharged, realizing the integrated grinding process of titanium dioxide.

[0028] like Figure 4 and Figure 5 As shown, a bushing 62 is sleeved on the outer wall of the drive shaft 61, and sweeping plates 621 extend from both sides of the bushing 62. The bottom end of the sweeping plates 621 is attached to the bottom of the discharge bin 2.

[0029] Specifically, during the grinding process, the drive shaft 61 drives the sweeping plate 621 to rotate continuously in the discharge bin 2 through the bushing 62, so that the powder falling into the discharge bin 2 can be swept out in time, avoiding the accumulation of powder in the discharge bin 2. The grinding process and the sweeping process work together to ensure the efficiency and stability of the feeding process.

[0030] like Figure 6 and Figure 7 As shown, a connecting plate 73 is fixedly provided at the upper end of the moving grinding disc 72, and a movable groove 631 is provided in the fixed seat 63. The connecting plate 73 is movably installed in the movable groove 631. Guide posts 632 are fixedly provided at both ends of the movable groove 631. The guide posts 632 slide through the connecting plate 73. A screw sleeve 731 is fixedly provided in the center of the connecting plate 73. An adjusting screw 741 is connected to the output end of the adjusting motor 74. The bottom end of the adjusting screw 741 is threaded through the screw sleeve 731 and rotates with the fixed seat 63.

[0031] Specifically, during the spacing adjustment process, the adjusting motor 74 drives the adjusting screw 741 to rotate. The adjusting screw 741, through the screw sleeve 731, drives the connecting plate 73 to move up and down within the movable groove 631, thereby adjusting the spacing between the moving grinding disc 72 and the fixed grinding disc 71. During this process, the connecting plate 73 is constrained by the guide post 632, so that the moving grinding disc 72 can only make axial displacement relative to the fixed seat 63, while the drive shaft 61 can still drive the moving grinding disc 72 to rotate synchronously through the fixed seat 63.

[0032] It should be noted that in actual use, a displacement sensor can be installed in the fixed base 63 to monitor the adjustment displacement distance of the connecting plate 73 in real time, so as to accurately detect the spacing adjustment process between the moving grinding disc 72 and the fixed grinding disc 71, effectively improving the accuracy of spacing adjustment.

[0033] like Figure 6 As shown, the upper end of the fixed base 63 is covered with a top base 64, and extension plates 641 are evenly arranged on the outer wall of the top base 64. Material distribution plates 642 are arranged on both sides of the extension plates 641.

[0034] Specifically, the top seat 64 is installed on the outside of the regulating motor 74, which protects the regulating motor 74 and prevents powder from entering the interior and affecting the operation of the regulating motor 74. At the same time, the top seat 64 drives the material distribution plate 642 to rotate synchronously, which can effectively disperse the material and make it evenly distributed.

[0035] like Figure 5 and Figure 6 As shown, the upper surface of the fixed grinding disc 71 is a concave slope. Several feeding grooves 711 are evenly provided through the bottom of the slope. The feeding grooves 711 are connected to the discharge bin 2. The top of the slope extends upward and is provided with a baffle ring protrusion 712.

[0036] Furthermore, the lower surface of the moving grinding disc 72 is an outwardly convex inclined surface, and the bottom end of the moving grinding disc 72 is adapted to the top end of the fixed grinding disc 71. Several screening holes 721 are provided through the moving grinding disc 72, and a feeding ring protrusion 722 is provided on the outer edge of the moving grinding disc 72 extending upward.

[0037] Specifically, the inclined surface fit between the fixed grinding disc 71 and the moving grinding disc 72 effectively increases the contact area between them, allowing more material to enter the gap between them for crushing and extrusion, thereby improving grinding efficiency. The sieve holes 721 on the moving grinding disc 72 can effectively screen out and isolate large particles and impurities mixed in with the raw materials, preventing impurities from affecting the quality of the powder.

[0038] like Figure 2 and Figure 8 As shown, a discharge port 21 is connected to one side of the discharge bin 2, and a feed port 41 is provided at the upper end of the feed bin 4. One side of the inner wall of the feed bin 4 is inclined, and the feed port 41 is located above the inclined wall. A vibrating assembly 8 is provided at the bottom of the feed bin 4.

[0039] Furthermore, the vibrating material assembly 8 includes a fixed frame 81, which is fixedly mounted at the bottom of the feed hopper 4. A support 811 is mounted on the fixed frame 81, and a vibrating material block 82 is mounted inside the support 811. A connecting rod 821 is fixedly mounted in the center of the vibrating material block 82. The connecting rod 821 slides through the support 811 and is connected to a contact plate 823. A return spring 822 is mounted between the contact plate 823 and the support 811. Guide rods 824 are fixedly mounted at both ends of the vibrating material block 82. The guide rods 824 slide through the support 811. A servo motor 83 is fixedly mounted on one side of the fixed frame 81. A cam 831 is mounted at the output end of the servo motor 83. The outer wall of the cam 831 abuts against the contact plate 823.

[0040] Specifically, by setting up the vibrating material assembly 8, during the grinding process, the servo motor 83 drives the cam 831 to rotate. During the rotation, the cam 831 presses the contact plate 823 and drives the vibrating material block 82 to reciprocate through the connecting rod 821. This causes the vibrating material block 82 to apply a reciprocating striking action to the feed bin 4. The raw materials accumulated on the side wall of the feed bin 4 are dislodged and fall under the vibration, which can effectively prevent the accumulation of materials in the feed bin 4 and facilitate the continuous grinding process of continuous materials.

[0041] The working principle of this invention is as follows: Figures 1-8As shown, during use, raw materials are added to the feed hopper 4 through the feed inlet 41. The feeding motor 5 drives the shaft 51 and the feeding auger 52 to rotate, so that the raw materials enter the grinding chamber 3 from the feed hopper 4. At the same time, the drive motor 6 drives the moving grinding disc 72 to rotate through the fixed base 63. Together with the fixed grinding disc 71, it applies crushing and shearing action to the material to grind it into fine powder. During grinding, the adjusting motor 74 drives the adjusting screw 741 to rotate. The adjusting screw 741 drives the connecting plate 73 to move up and down in the movable groove 631 through the screw sleeve 731, thereby realizing the adjustment of the distance between the moving grinding disc 72 and the fixed grinding disc 71. This can effectively control the degree of grinding and the output particle size of the powder, which is conducive to improving the grinding quality. The ground powder falls into the discharge hopper 2. The drive shaft 61 drives the sweeping plate 621 to rotate continuously in the discharge hopper 2 through the bushing 62, so that the powder falling into the discharge hopper 2 can be swept and discharged in time, avoiding the accumulation of powder in the discharge hopper 2. At the same time, the servo motor 83 drives the cam 831 to rotate. During the rotation, the cam 831 presses the contact plate 823 and drives the vibrating block 82 to extend back and forth through the connecting rod 821. This causes the vibrating block 82 to apply a reciprocating striking action to the feed bin 4. The raw materials accumulated on the side wall of the feed bin 4 fall off under the vibration, which can effectively prevent the accumulation of materials in the feed bin 4 and is conducive to the continuous grinding and processing of continuous materials.

[0042] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
