Description

Technical Field

[0001] The utility model relates to the technical field of coating grinding, in particular to a grinding device for processing high-performance and high-temperature resistant coating raw materials. Background Art

[0002] Fire retardant coatings are applied to surfaces to improve their fire resistance, thereby preventing combustion. Fire retardant coatings must possess low thermal conductivity, high-temperature resistance, and resistance to decomposition. The quality of these properties is often related to the coating's properties and formulation, as well as the compounding, dispersion, and grinding processes used during production.

[0003] Currently, common high-temperature resistant fire-retardant coatings include nano-coatings. During their production process, large particles or clumped precipitates in the coating need to be ground and dispersed to a certain fineness. Dispersion and grinding equipment are often used in the prior art. The grinding equipment disclosed in the prior art mostly uses grinding rollers, grinding rods, grinding balls or grinding discs to grind the powder in a single pass. For example, a water-based nano-coating grinding device disclosed in Chinese patent announcement number CN209174026U, and a nano water-based coating high-efficiency grinding device disclosed in Chinese patent CN220277063U. However, nano-coatings have very strict requirements on indicators such as uniformity, weather resistance, and glossiness, and it is often difficult to meet the requirements with a single grinding.

[0004] The prior art also discloses grinding equipment that can achieve a secondary grinding function, but usually the paint after the initial grinding is transported back to the grinding chamber for secondary grinding through a conveying mechanism. Such a design uses one device to repeatedly grind the same batch of paint, with a single grinding method and poor dispersion effect. In addition, new paint cannot be input before the paint is finally ground, resulting in low grinding efficiency. When grinding multiple batches of paint, cross-contamination is also likely to occur, affecting quality. For example, the Chinese patent with announcement number CN213966868U discloses an automatic secondary grinding paint grinder, and the Chinese patent with announcement number CN108722560B discloses a paint grinding device.

[0005] Therefore, there is an urgent need in the prior art to invent a coating grinding device that can meet the secondary grinding function of high-temperature resistant coatings and has high processing efficiency. Utility Model Content

[0041] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] See also Figure 1 、 Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, a grinding device for high-performance, high-temperature-resistant coatings includes a first grinding mechanism 1, which includes a pipe 11, a screw 12, and a discharge barrel 14. The screw 12 is rotatably disposed within the pipe 11 and is provided with spiral blades 121. One end of the pipe 11 is provided with a feed port 17, and the other end is provided with a discharge barrel 14. The first grinding mechanism 1 is used to pressurize and crush the coating raw materials to achieve a fine grinding effect, ensuring high fineness and uniform and stable particle size after grinding.

[0045] Specifically, see Figure 3 and Figure 4 As shown, the feed port 17 is connected to the inside of the pipeline 11, and is used to put the paint raw materials to be ground into the pipeline 11, which can be specifically set to a funnel shape; when the screw 12 rotates inside the pipeline 11, the paint raw materials put into the feed port 17 can be transported to the end of the pipeline 11 close to the discharge barrel 14 through the spiral blades 121 spirally distributed on its outer side; the size of the outlet end of the discharge barrel 14 is smaller than the size of the inlet end, and is used to play the role of concentrating and gathering the paint.

[0046] Furthermore, a grinding section 122 is provided at one end of the screw 12 close to the discharge barrel 14, and a grinding chamber (not shown in the figure) is formed between the outer wall of the grinding section 122 and the inner wall of the pipe 11 corresponding to the grinding section 122. The screw 12 transports the coating raw materials to the grinding chamber to complete the initial fine grinding operation of the coating raw materials.

[0047] See also Figure 1 、 Figure 2 and Figure 5 As shown, the grinding device for high-performance, high-temperature-resistant coatings further includes a second grinding mechanism 2, which includes a grinding container 21 and a container cover 22. The container cover 22 is located above the grinding container 21. The container cover 22 is provided with an opening corresponding to the outlet of the discharge barrel 14. The opening is larger than the outlet of the discharge barrel 14, ensuring that the coating discharged from the discharge barrel 14 accurately falls into the grinding container 21 without splashing. The grinding container 21 is rotatable relative to the container cover 22. Specifically, the second grinding mechanism 2 is used to perform high-speed rotational grinding on the coating raw materials after the initial grinding, so that they are further ground and evenly dispersed, meeting the performance requirements of the finished coating, such as uniformity and weather resistance.

[0048] Specifically, see Figure 2 and Figure 5 As shown, the container lid 22 is detachably provided with a grinding rod 23 that extends into the grinding container 21, and a grinding ball 231 that is detachably mounted at the bottom end of the grinding rod 23. When the grinding container 21 rotates relative to the container lid 22, the grinding ball 231 at the bottom end of the grinding rod 23 can perform a secondary grinding of the coating material in the grinding container 21. The specific principle is as follows: the coating material generates centrifugal force under the rotation of the grinding container 21 and is thrown toward the inner sidewall of the grinding container 21. During the rotation, the coating material is squeezed and ground in the gap between the grinding ball 231 and the inner sidewall of the grinding container 21, thereby achieving a grinding effect. In addition, the grinding rod 23 and the grinding ball 231 can also stir and disperse the high-speed rotating coating material.

[0049] Furthermore, the grinding rod 23 and the container cover 22 are detachably connected, and the grinding ball 231 and the grinding rod 23 are detachably connected. By replacing the grinding rods 23 of different specifications or replacing the grinding balls 231 of different sizes, and adjusting the rotation speed of the grinding container 21, the size of the gap between the grinding balls 231 and the inner wall of the grinding container 21 can be adjusted, thereby adjusting the extrusion force on the coating raw materials and the stirring and dispersion effect on the coating raw materials.

[0050] In the technical solution of this embodiment, the first grinding mechanism 1 completes a single grinding operation on the paint and then transports it to the second grinding mechanism 2. The second grinding mechanism 2 then performs a secondary grinding operation on the paint, and finally outputs the finished product of the ground paint. The entire process is well-organized, and there is no need to repeatedly transport the once-ground paint back to the original first grinding mechanism 1. Multiple batches of paint to be ground can be continuously input while the paint is being output, resulting in high processing efficiency and no cross-contamination issues. Moreover, the two grinding operations of the first grinding mechanism 1 and the second grinding mechanism 2 cooperate with each other, and the grinding effect can be significantly improved compared to the single repeated grinding method of transporting the paint back to the original grinding mechanism in the prior art.

[0051] Example 1

[0052] In a preferred embodiment of the present invention, a technical solution for the specific structural design of the first grinding mechanism 1 is provided.

[0053] See also Figure 4 As shown, in the technical solution of this embodiment, a plurality of first protrusions (not shown) are spaced apart on the outer wall of the grinding section 122, and a plurality of second protrusions (not shown) are spaced apart on the inner wall of the pipe 11 corresponding to the grinding section 122. The first protrusions and the second protrusions are arranged in an interlaced manner. When the screw 12 conveys the coating material into the grinding chamber, the relative rotation between the interlaced first and second protrusions acts as a rolling and grinding action on the coating material, thereby improving the grinding effect and grinding efficiency of the coating material. At the same time, the design of the first and second protrusions can prevent and eliminate the adhesion of the coating material to the outer wall of the grinding section 122 or the inner wall of the pipe 11, avoiding pipe blockage or even pipe damage when the coating material is continuously input.

[0054] See also Figure 3 and Figure 4 As shown, in an optional solution of this embodiment, the first grinding mechanism 1 further includes a discharge plate 13, which is fixedly mounted at the end of the pipe 11, and a discharge barrel 14 is disposed at the end of the discharge plate 13 away from the pipe 11. A plurality of discharge holes 131 are disposed around the discharge plate 13, and the discharge holes 131 are configured to connect the grinding chambers on both sides of the discharge plate 13 with the discharge barrel 14. Specifically, after the coating raw materials conveyed by the screw 12 undergo the grinding operation in the grinding chamber, they are discharged into the discharge barrel 14 through the plurality of discharge holes 131 and then discharged into the second grinding mechanism 2 through the discharge barrel 14.

[0055] Compared with the design method of directly discharging the rolled and ground paint raw materials to the second grinding mechanism 2 through the discharge barrel 14, this embodiment allows the paint raw materials in the grinding chamber to be fully rolled and ground by the first protrusion and the second protrusion under the pressure on its left and right sides (that is, under the conveying pressure of the left screw 2 and the blocking pressure of the right discharge plate 13) and then discharged from the discharge hole 13 in a concentrated manner, thereby preventing incomplete grinding of the paint.

[0056] In particular, the number of discharge holes 131 can be adjusted based on actual needs by selecting different specifications and models of discharge plates 13. For example, when the conveying pressure applied by the screw 12 is high, a discharge plate 13 with a large number of discharge holes 131 can be selected to avoid pipe blockage; when the conveying pressure applied by the screw 12 is low, a discharge plate 13 with a small number of discharge holes 131 can be selected.

[0057] Further, see Figure 4 As shown, the first grinding mechanism 1 also includes a sealing shaft 15, which is fixedly mounted at the center of the discharge plate 13. The screw 12 is rotatably mounted on the sealing shaft 15 via a bearing. The sealing shaft 15 not only seals the pipe 11, ensuring that the coating material in the grinding chamber is discharged from the discharge hole 131 in a centralized manner, but also supports the rotation of the screw 12, ensuring that both ends of the screw 12 along its length have a support point.

[0058] Further, see Figure 3 As shown, the diameter of screw 12 gradually increases from feed port 17 to discharge barrel 14, thereby gradually reducing the space between the outer side of screw 12 and the inner wall of the pipe. This structural design ensures that the coating material in pipe 11 is continuously subjected to increasing compressive stress from screw 11 and the inner wall of pipe 11 during the conveying process of screw 12, thereby achieving a pressurizing effect. This pressurized coating material is then conveyed to the grinding chamber, enhancing the grinding effect and further improving the fine grinding effect of the coating material.

[0059] Example 2

[0060] In another preferred embodiment of the present invention, a technical solution for the power and transmission system of the grinding device is provided.

[0061] See also Figure 5As shown, in the technical solution of this embodiment, the grinding device for high-performance, high-temperature-resistant coatings further includes a base 3, on which a column 4 is fixedly mounted. A fixing ring 41 is provided at the top of the column 4 and is sleeved on the outer circumference of the pipe 11. The fixing ring 41 is used to support and secure the pipe 11, while also ensuring that the pipe 11 has a certain height relative to the base 3, ensuring that after the first grinding mechanism completes the initial grinding of the coating raw material, the material can flow from the higher position through the discharge barrel 14 into the lower grinding container 21.

[0062] See also Figure 5 As shown, in an alternative embodiment of this embodiment, the second grinding mechanism 2 further includes a worm gear shaft 24 and a worm 25. The grinding container 21 is rotatably mounted on the base 3 via the worm gear shaft 24. A worm wheel 241 on the worm gear shaft 24 is meshed with helical teeth 251 on the worm 25. In this structural design, rotating the horizontally disposed worm 25 drives the worm gear shaft 24, which in turn drives the grinding container 21, thereby grinding the coating material in the container.

[0063] Further, see Figure 5 As shown, the column 4 is further provided with a fixing rod 42, which is fixedly connected to the container cover 22, thereby ensuring that during the rotation of the grinding container 21, the container cover 22 is not disturbed by the rotation of the grinding container 21, so that the grinding rod 23 on the container cover 22 can achieve a grinding effect.

[0064] See also Figure 1 As shown, in another optional scheme of this embodiment, the grinding device for high-performance high-temperature resistant coatings further includes a motor 5 and a gearbox 6 provided on the base 3. The input ends of the motor 5 and the gearbox 6 are connected. The gearbox 6 is provided with a first output end 7 and a second output end 8. The first output end 7 is connected to the screw 12 for driving the screw 12 to rotate; the second output end 8 is connected to the worm 25 via a belt transmission assembly 9 for driving the worm 25 to rotate. Specifically, the motor 5 is used as a power mechanism for the first grinding mechanism 1 and the second grinding mechanism 2, and the gearbox 6 is used as a transmission mechanism between the motor 5 and the first grinding mechanism 1 and the second grinding mechanism 2. In the scheme of this embodiment, the first grinding mechanism 1 and the second grinding mechanism 2 adopt a set of power assemblies. The different speed requirements of the two grinding mechanisms can be met by the same motor 5 power output source and different transmission systems in the gearbox 6. The cost is low, the structural design is simple and reasonable, and the space occupation is reduced, which is convenient for maintenance and operation.

[0065] Further, see Figure 6As shown, the gearbox includes a housing 61 and a first transmission shaft 62, a second transmission shaft 63, and a third transmission shaft 65 arranged in the housing 61. The second transmission shaft 63 is fixedly provided with a first transmission gear 64, and the third transmission shaft 65 is fixedly provided with a second transmission gear 66. The external teeth on the first transmission shaft 62 are meshed with the first transmission gear 64, and the external teeth on the second transmission shaft 63 are meshed with the second transmission gear 66. Among them, the first transmission shaft 62 is the input end of the gearbox 6, the second transmission shaft 63 is connected to the second output end 8, and the third transmission shaft 65 is connected to the first output end 7. Specifically, when the motor 5 is started, the motor 5 drives the first transmission shaft 62 to rotate through its output shaft, and then drives the second transmission shaft 63 to rotate through the meshing connection between the external teeth of the first transmission shaft 62 and the first transmission gear 64, and then drives the second output end 8 to rotate, thereby driving the second grinding mechanism 2. Furthermore, the rotation of the second transmission shaft 63 can drive the third transmission shaft 65 to rotate through the meshing connection between the outer teeth of the second transmission shaft 63 and the second transmission gear 66 , thereby driving the first output end 7 to rotate, thereby driving the first grinding mechanism 1 .

[0066] See also Figure 2 As shown, in another alternative embodiment of this embodiment, the high-performance, high-temperature-resistant coating grinding device further includes a first shield 31 and a second shield 32 disposed on the base 3. The motor 5, the gearbox 6, the first output end 7, and the second output end 8 are disposed within the first shield 31. The worm 25 is rotatably connected to the first shield 31. The worm gear shaft 24 and the connection between the worm gear shaft 24 and the worm 25 are disposed within the second shield 32. The first shield 31 is used to enclose and protect the motor 5, the gearbox 6, the first output end 7, and the second output end 8, preventing the connection between the shafts and the meshing between the gears and the external teeth from being disturbed by external dust or other impurities, which could affect the working accuracy or cause damage. Similarly, the second shield 32 is used to enclose and protect part of the worm gear shaft 24 and the worm 25, preventing the connection between the worm gear shaft 24 and the base 3 and the meshing between the worm gear 241 and the helical teeth 251 from being disturbed by external dust or other impurities, which could affect the working accuracy or cause damage.

[0067] In summary, the first grinding mechanism 1 of the present invention completes a grinding operation on the paint once and then transports it to the second grinding mechanism, and then the second grinding mechanism 2 completes a second grinding operation on the paint, and finally outputs the finished paint product. The entire process is orderly, and there is no need to repeatedly transport the paint raw materials after the first grinding back to the first grinding mechanism 1. Multiple batches of paint to be ground can be continuously input while the paint is output, and the processing efficiency is high and there is no problem of cross-material. In addition, the first grinding mechanism 1 is used to perform a pressurized rolling operation on the paint to achieve a fine grinding effect, ensuring that the paint has high fineness and uniform and stable particle size after grinding; the second grinding mechanism 2 is used to perform high-speed rotation grinding on the paint after the initial grinding so that it is further ground and achieves a uniform dispersion effect, meeting the uniformity, weather resistance and other performance requirements of the finished paint product; the two grindings cooperate with each other, and compared with the single repeated grinding method of transporting the paint back to the original grinding mechanism, the grinding effect can be significantly improved.

[0068] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
