Description

Technical Field

[0001] The utility model relates to the technical field of grinding and fine screening, in particular to a grinding and fine screening mechanism for water-based paint ingredients. Background Art

[0002] Grinding and screening water-based paint ingredients is a crucial step in its production. It involves uniformly mixing raw materials such as pigments and resins and refining them to an appropriate particle size to improve the quality and gloss of the paint film. During the grinding and dispersion stage, the mixed water-based paint is placed in a grinder for refining. This step aims to make the pigment and resin particles smaller, thereby improving the uniformity and stability of the paint film. The fine screening process ensures that there are no large particles in the ground paint, ensuring the paint's fineness and workability. This process is crucial to the final performance of the water-based paint, as it directly affects the paint's coating effect and surface condition after drying. Therefore, a grinding and screening mechanism is required to produce ingredients with a high degree of fineness.

[0003] Therefore, a water-based paint ingredient grinding and fine screening mechanism is proposed to solve or alleviate the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a water-based paint ingredient grinding and fine screening mechanism.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A water-based paint ingredient grinding and fine screening mechanism includes a receiving hopper, an annular outer grinding disc located above the receiving hopper, an inner grinding disc rotatably arranged on the inner ring of the outer grinding disc, and an annular channel arranged above the inner grinding disc, wherein the inner bottom surface of the annular channel is provided with a plurality of through holes, and the bottom surface of the annular channel is fixedly connected to a material pipe connected to the through holes, the outlet of the material pipe is located on the top surface of the inner grinding disc and there is a gap between the outlet of the material pipe and the top surface of the inner grinding disc, and the thickness of the inner grinding disc is less than that of the outer grinding disc.

[0007] Preferably, the top of the inner ring of the outer grinding disc is provided with an inclined guide bevel, the top outer ring of the inner grinding disc is provided with a chamfer, the inner ring of the outer grinding disc is provided with a vertical grinding surface intersecting with the guide bevel, the outer ring of the inner grinding disc is provided with an outward-expanded grinding surface located below the vertical grinding surface, and the inner ring of the outer grinding disc is fitted with the outer ring of the inner grinding disc.

[0008] Preferably, a circle of inclined material guide plates is fixedly connected to the bottom surface of the outer grinding disc, and the inner diameter of the inclined material guide plates is gradually reduced from top to bottom, and the minimum inner diameter of the inclined material guide plates is smaller than the maximum inner diameter of the receiving hopper.

[0009] Preferably, the bottom end of the receiving hopper is connected to a discharge pipe, and the discharge pipe is connected to a solenoid valve.

[0010] Preferably, it further comprises a stand, the material receiving hopper is fixedly connected in the stand, and the outer grinding disc is fixedly connected in the stand.

[0011] Preferably, a gantry is fixedly connected to the top of the stand, a vertically arranged servo motor is fixedly connected to the gantry, the output shaft of the servo motor is coaxially connected to an upper connecting turntable rotatably arranged on the inner ring of the annular track, the upper connecting turntable is fixedly connected to the lower connecting turntable through a plurality of connecting rods, and the lower connecting turntable is coaxially fixedly connected to the top surface of the inner grinding disk.

[0013] The utility model has the following beneficial effects:

[0014] This new grinding process is simple and efficient. The operator simply pours the raw material into the hopper, where it flows under its own weight into the circular channel, gradually filling it. Within the circular channel, the raw material is evenly distributed onto the top surface of the inner grinding disc through holes and a feed pipe. Driven by a servo motor, the inner grinding disc slowly rotates in conjunction with the outer grinding disc, generating centrifugal force that spreads the raw material outward between the chamfered corners and the guide bevel. This process, which utilizes both vertical and outward grinding surfaces, ensures that the raw material is thoroughly ground. The ground material then converges on the inner ring of the inclined guide disc, where it accumulates to a sufficient level and falls into the receiving hopper. When the hopper reaches a certain level, the material is discharged through a discharge pipe controlled by a solenoid valve. If the circular channel becomes insufficient, the above steps are repeated. This design eliminates the need for additional filtration and enables simultaneous grinding and fine screening, simplifying equipment requirements, improving grinding efficiency, and ensuring the fineness of the raw material.

[0027] A water-based paint ingredient grinding and fine screening mechanism, such as Figure 1 and Figure 2 As shown, it includes a stand 1, a hopper 2, an annular outer grinding disc 11 located above the hopper 2, an inner grinding disc 10 rotatably arranged on the inner ring of the outer grinding disc 11, and an annular track 14 arranged above the inner grinding disc 10. The outer grinding disc 11 is fixedly connected to the stand 1, and a gantry 5 is fixedly connected to the top of the stand 1. A vertically arranged servo motor 6 is fixedly connected to the gantry 5. The output shaft of the servo motor 6 is coaxially connected to an upper connecting turntable 7 rotatably arranged on the inner ring of the annular track 14. The upper connecting turntable 7 is fixedly connected to the lower connecting turntable 9 through a plurality of connecting rods 8. The lower connecting turntable 9 is coaxially fixedly connected to the top surface of the inner grinding disc 10. A feeding hopper 12 is fixedly connected to one side of the gantry 5. Figure 3 As shown, the bottom of the feed hopper 12 is connected to a material rail 13, the lower end of the material rail 13 is connected to the annular channel 14, and the inner bottom surface of the annular channel 14 is provided with a plurality of through holes 16, and the bottom surface of the annular channel 14 is fixedly connected to a material pipe 15 connected to the through holes 16, and the outlet of the material pipe 15 is located on the top surface of the inner grinding disk 10 and there is a gap between the outlet of the material pipe 15 and the top surface of the inner grinding disk 10.

[0028] The bottom end of the receiving hopper 2 is connected to a discharge pipe 153 . The receiving hopper 2 is fixedly connected to the vertical frame 1 . The discharge pipe 153 is connected to a solenoid valve 4 .

[0029] like Figure 4 As shown, the thickness of the inner grinding disc 10 is smaller than that of the outer grinding disc 11, the top of the inner ring of the outer grinding disc 11 is provided with an inclined guide slope 18, the top outer ring of the inner grinding disc 10 is provided with a chamfer, the inner ring of the outer grinding disc 11 is provided with a vertical grinding surface 19 intersecting with the guide slope 18, the outer ring of the inner grinding disc 10 is provided with an outward-expanded grinding surface 20 located below the vertical grinding surface 19, the inner ring of the outer grinding disc 11 is fitted with the outer ring of the inner grinding disc 10, and the bottom surface of the outer grinding disc 11 is fixedly connected with a circle of inclined guide discs 17, the inner diameter of the inclined guide discs 17 is gradually reduced from top to bottom, and the minimum inner diameter of the inclined guide disc 17 is smaller than the maximum inner diameter of the receiving hopper 2.

[0030] When the present invention is actually performing grinding work, the operator only needs to introduce the ingredients into the feed hopper 12 by pouring, and then under the action of the dead weight of the ingredients, the ingredients flow into the annular channel 14 through the material rail 13, and the ingredients gradually fill the entire annular channel 14. When the ingredients are in the annular channel 14, the ingredients can flow down through the through hole 16 and the material pipe 15, so that the ingredients can be relatively evenly distributed on the top surface of the inner grinding disc 10. Driven by the servo motor 6, the servo motor 6 is driven by a series of drives such as the upper connecting turntable 7, the connecting rod 8, and the lower connecting turntable 9. The inner grinding disc 10 rotates slowly on the inner ring of the outer grinding disc 11. The inner grinding disc 10 will generate a centrifugal force to diffuse outward on the ingredients, causing the ingredients to diffuse outward, and then enter between the chamfer and the guide slope 18, and between the dead weight of the ingredients and the cooperation between the inner grinding disc 10 and the outer grinding disc 11. Under the present invention, the ingredients enter between the inner grinding disc 10 and the outer grinding disc 11 for fine grinding. The ingredients need to be ground by the vertical grinding surface 19 and the outward-expanding grinding surface 20 to increase the grinding process, so that the ingredients can be carefully ground by the inner grinding disc 10 and the outer grinding disc 11, and then flow out from between the inner grinding disc 10 and the outer grinding disc 11, adhere to the inner circle of the inclined guide disc 17, and converge. After a certain amount of liquid is gathered, the finely ground ingredients can fall into the receiving hopper 2 for accumulation. After a certain amount of accumulation, the solenoid valve 4 is opened to discharge the material through the discharge pipe 153. If the ingredients in the annular channel 14 are insufficient, the above operation can be repeated. In this way, people can obtain more finely ground ingredients, and use the inner grinding disc 10 and the outer grinding disc 11 to simultaneously perform fine grinding and fine screening. There is no need to add a filtering structure, which simplifies the equipment required for fine grinding and screening.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
