Description

Technical Field

[0001] The present invention relates to the technical field of grinding, and particularly to a raw material grinding device for the production of waterborne coatings. Background Art

[0002] Waterborne coatings refer to coatings that use water as a solvent or a dispersion medium, and have the characteristics of low volatility, non-toxic and odorless, and easy to clean. However, due to the different textures of pigments and binders, problems such as viscosity, precipitation, and caking are likely to occur. Through grinding, pigment particles can be dispersed in the coating matrix to achieve a uniform dispersion effect, which helps to improve the stability and uniformity of the coating, prevent precipitation and stratification during storage and use, and thus ensure the stability and consistency of the coating effect.

[0003] In the prior art, the grinding of waterborne coatings usually uses vertical grinders and horizontal grinders. Both use the friction and collision between grinding media to grind the materials. After a certain residence time, a slurry with a particle size distribution meeting the requirements is obtained. In actual use, when both stop, the grinding media are at the bottom of the grinding cylinder. When starting, a strong friction is generated between the stirring shaft and the beads. Since the grinding beads are too concentrated, bead breakage is likely to occur, and the grinding process needs to be carried out under sealed conditions, which is not convenient for discharging materials.

[0004] Therefore, it is urgent to improve the raw material grinding device for the production of waterborne coatings to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a raw material grinding device for the production of waterborne coatings, which can drive grinding balls to rotate on a grinding disc through a bevel gear disc via a plurality of human-shaped mounting columns. The fine and uniform slurry can enter the interior of the funnel through an iron cloth filter screen and be discharged through a discharge pipe, changing the traditional grinding method by the shearing force of grinding beads. The grinding balls roll and grind the raw materials on a fixed track, so the probability of grinding ball breakage is greatly reduced, and the functions of feeding and discharging are synchronized through a feed inlet and a discharge pipe, greatly improving the production efficiency of waterborne coatings.

[0011] Preferably, an arc-shaped protection plate is fixedly installed at the bottom end of the human-shaped mounting column. The grinding ball is rotatably arranged inside the arc-shaped protection plate. Scraping mechanisms are fixedly installed at both ends of the arc-shaped protection plate.

[0012] Preferably, a plugging rod is fixedly installed at the bottom side of the arc-shaped protection plate. The plugging rod extends into the grinding ball. A plugging pile is rotatably arranged inside the grinding ball. A spline is fixedly arranged at the end of the plugging rod away from the grinding ball. The spline corresponds to the plugging pile.

[0013] Preferably, the scraping mechanism includes a diversion scraper and a side wall scraper. The bottom side of the diversion scraper is in contact with the side surface of the material distributing cone. One end of the diversion scraper extends to the bottom side of the grinding ball. One side of the side wall scraper is in contact with the inner side walls of the feeding cylinder and the iron cloth filter screen. During the rotation of the bevel gear disk, the side wall scraper is not in contact with the grinding ball.

[0014] Preferably, a screw conveyor rod is rotatably arranged inside the discharge pipe. A shaft rod is fixedly arranged inside the screw conveyor rod. One end of the shaft rod extends into the operating table. A pump is fixedly arranged at the end of the discharge pipe away from the operating table. The other end of the shaft rod is fixedly connected to the input shaft of the pump.

[0015] Preferably, a servo motor is fixedly installed inside the operating table. The output end of the servo motor is fixedly connected to one end of the shaft rod.

[0016] Preferably, a bevel gear is meshed and connected to the upper end of the feeding cylinder, a driving rod of the bevel gear extends into the interior of the operating table, a sprocket is fixedly installed at one end of the shaft rod and the bevel gear located inside the operating table, a chain is rotatably arranged outside the sprocket, and the shaft rod and the bevel gear rotate synchronously through the chain.

[0017] Preferably, a U-shaped bracket is fixedly arranged on the outer side of the funnel, and one end of the U-shaped bracket away from the funnel is fixedly installed on the side surface of the feeding port by screws.

[0018] Preferably, a Z-shaped fixing plate is fixedly installed on the side surface of the feeding cylinder, one end of the Z-shaped fixing plate away from the feeding cylinder is fixedly installed on the operating table by bolts, and a driving rod of the bevel gear penetrates through the Z-shaped fixing plate and extends into the interior of the operating table.

[0019] The present invention at least has the following beneficial effects:

[0020] The present invention can drive the grinding balls to rotate on the grinding disc through a bevel gear disc and a plurality of human-shaped mounting columns. The delicate and uniform slurry can enter the interior of the funnel through the iron cloth filter screen and be discharged through the discharge pipe, changing the traditional grinding method by the shearing force of grinding beads. The grinding balls roll and grind the raw materials on the fixed track, so the probability of the grinding balls breaking is greatly reduced, and the functions of feeding and discharging synchronously are realized through the feeding port and the discharge pipe, greatly improving the production efficiency of the water-based paint.

[0021] After the raw materials of the present invention enter the feeding cylinder through the feeding port, they first contact the top end of the material distribution cone, and the raw materials flow along the side wall of the material distribution cone to the bottom of a plurality of grinding balls, which can make the feeding more uniform. During the rotation of the bevel gear disc, the grinding balls roll along the grooves inside the grinding disc through the inserting rods and inserting piles. Under the cyclic rolling action of the grinding balls, the raw materials become delicate and uniform, thus having a better grinding effect.

[0022] During the rotation of the bevel gear disc of the present invention, the diversion scraper and the side wall scraper scrape the raw materials adhered to the side walls of the material distribution cone, the feeding cylinder and the iron cloth filter screen following the rotation of the human-shaped mounting column, and the adhered raw materials enter the grooves of the grinding disc through the bottom edge of the diversion scraper and the inclination angle of the side wall scraper, having a good grinding effect on the water-based materials with high viscosity.

[0023] The ground slurry converges into the interior of the discharge pipe at the bottom through the funnel. The servo motor drives the auger conveying rod through the shaft rod to convey the water-based paint. On the one hand, it is convenient for the water-based paint to be discharged, and on the other hand, it can be stirred while discharging to prevent the water-based paint from coagulating and generating precipitation. Moreover, the auger conveying rod can play a role in forcibly pushing the water-based paint with high viscosity, so as to prevent the discharge port from being blocked.

[0024] In the present invention, the servo motor drives the auger conveying rod through the shaft rod to convey the water-based paint. While the auger conveying rod stirs the water-based paint, it can drive the pump to extract it. When the pump works, a negative pressure is generated inside the funnel, so that the outside air enters the discharging cylinder from the feeding port. The air can adsorb the raw material slurry through the iron cloth filter screen. On the one hand, the filtration efficiency of the slurry is greatly improved, and on the other hand, the iron cloth filter screen can be prevented from being blocked, thereby greatly extending the service life of the grinding device.

[0025] In the present invention, through the connection of the chain and the sprocket, the shaft rod and the bevel gear can rotate synchronously, so as to ensure the coordinated rotation and operation of the bevel gear disk, and ensure the operation stability and coherence of the whole device. The driving component is arranged inside the operation platform, which is convenient for the operator to control and monitor the equipment at the same position. The operator can more conveniently adjust the operation parameters of the equipment, improve the operation efficiency and reduce the setting of the power system, thereby saving costs.

Specific embodiments

[0037] The following will detail the implementation manners of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0038] As Figure 1 - Figure 9 shown, the raw material grinding device for water-based paint production provided in this embodiment includes an operating table 1 and a funnel 2 fixedly installed at the upper end of the operating table 1. A flange 3 is fixedly installed at the upper end of the funnel 2. An iron cloth filter screen 4 is fixedly installed at the bottom side of the flange 3. The bottom end of the iron cloth filter screen 4 is fixedly installed with a grinding disc 5. Both the iron cloth filter screen 4 and the grinding disc 5 are arranged inside the funnel 2. A discharging cylinder 6 is fixedly installed at the upper end of the flange 3. A bevel gear disc 7 is rotatably arranged inside the discharging cylinder 6. A plurality of evenly distributed humanoid mounting posts 8 are fixedly installed at the bottom side of the bevel gear disc 7. The bottom end of the humanoid mounting post 8 is rotatably provided with a grinding ball 9. The bottom side of the grinding ball 9 is in contact with the inner side of the grinding disc 5. The grinding ball 9 is rotatably arranged inside the iron cloth filter screen 4 and the grinding disc 5 through the bevel gear disc 7;

[0039] Principle: The operating table 1 is used to control the operation of the grinding device on the one hand and support the funnel 2 and the grinding disc 5 on the other hand, facilitating handling. The bevel gear disc 7 drives the grinding ball 9 to rotate on the grinding disc 5 through a plurality of humanoid mounting posts 8. The fine and uniform slurry can enter the inside of the funnel 2 through the iron cloth filter screen 4, changing the traditional grinding method by the shearing force of grinding beads. The grinding ball 9 rolls and grinds the raw materials on a fixed track, so the probability of the grinding ball breaking can be greatly reduced;

[0040] A discharge pipe 10 is fixedly arranged at the bottom end of the funnel 2. The inside of the discharge pipe 10 is communicated with the inside of the funnel 2. A feed inlet 11 is arranged inside the bevel gear disc 7. The feed inlet 11 is arranged above the iron cloth filter screen 4. A blanking guide rail 12 is fixedly installed at the upper end of the operating platform 1. The bottom end of the blanking guide rail 12 extends above the feed inlet 11.

[0041] Among them, the raw materials enter the discharging cylinder 6 from the feed inlet 11 through the blanking guide rail 12. The discharge pipe 10 is used for discharging. The ground slurry converges at the bottom of the funnel 2 and is discharged through the discharge pipe 10. The functions of feeding and discharging are synchronized through the feed inlet 11 and the discharge pipe 10, so that the production efficiency of the water-based paint can be greatly improved.

[0042] Further, as Figure 5 and Figure 9 shown, a material distribution cone 51 is fixedly arranged on the inner top side of the grinding disc 5. The material distribution cone 51 corresponds to the feed inlet 11. An inclined edge groove 52 is arranged at the edge of the grinding disc 5. The inclined edge groove 52 corresponds to the inner side wall of the funnel 2. An arc-shaped protection plate 13 is fixedly installed at the bottom end of the human-shaped mounting column 8. The grinding balls 9 are rotatably arranged inside the arc-shaped protection plate 13. Scraping mechanisms 14 are fixedly installed at both ends of the arc-shaped protection plate 13. A plugging rod 131 is fixedly installed at the bottom side of the arc-shaped protection plate 13. The plugging rod 131 extends into the grinding balls 9. A plugging pile 91 is rotatably arranged inside the grinding balls 9. A spline 132 is fixedly arranged at the end of the plugging rod 131 away from the grinding balls 9. The spline 132 corresponds to the plugging pile 91.

[0043] Among them; the spline 132 is used to connect the plugging rod 131 and the plugging pile 91. During the rotation of the bevel gear disc 7, the plugging rod 131 is in a horizontal state. A plurality of plugging rods 131 rotate around the vertical bisector of the cross-section of the material distribution cone 51. At this time, the plugging rod 131 is rotationally connected to the grinding balls 9 through the plugging pile 91. Therefore, the grinding balls 9 can roll along the grooves of the grinding disc 5. The arc-shaped protection plate 13 can scrape the raw materials adhered to the surface of the grinding balls 9 to prevent the volume of the grinding balls 9 from increasing and affecting the grinding effect.

[0044] Principle: After the raw materials enter the discharging cylinder 6 through the feed inlet 11, they first contact the top end of the material distribution cone 51. The raw materials flow along the side wall of the material distribution cone 51 to the bottom of a plurality of grinding balls 9, which can make the blanking more uniform. During the rotation of the bevel gear disc 7, the grinding balls 9 roll along the grooves inside the grinding disc 5 through the plugging rod 131 and the plugging pile 91. Under the cyclic rolling of the grinding balls 9, the raw materials become fine and uniform, with a good grinding effect. Therefore, the water-based paint can meet the product's requirements for fineness. Through the extrusion of the grinding balls 9, it contacts the iron cloth filter screen 4, and the uniform slurry flows into the funnel 2 through the inclined edge groove 52, thus facilitating collection.

[0045] To solve the problem of raw material adhesion:

[0046] As shown in Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, the scraping mechanism 14 includes a diversion scraper 141 and a side wall scraper 142. The bottom side of the diversion scraper 141 is in contact with the side surface of the material distribution cone 51, and one end of the diversion scraper 141 extends to the bottom side of the grinding ball 9. One side of the side wall scraper 142 is in contact with the inner side walls of the discharge cylinder 6 and the iron cloth filter screen 4. During the rotation of the bevel gear disk 7, the side wall scraper 142 is not in contact with the grinding ball 9, which can prevent the rotation of the grinding ball 9 from affecting the side wall scraper 142;

[0047] Among them, the arc-shaped protection plate 13 can scrape the raw materials adhered to the surface of the grinding ball 9 to prevent the volume of the grinding ball 9 from increasing and affecting the grinding effect. The diversion scraper 141 can scrape the raw materials adhered to the side wall of the material distribution cone 51. When the bevel gear disk 7 rotates clockwise, the raw materials can flow along the bottom side edge of the diversion scraper 141 to the bottom of the grinding ball 9. The side wall scraper 142 can scrape the raw materials adhered to the inner side walls of the discharge cylinder 6 and the iron cloth filter screen 4. The inclination angle of the side wall scraper 142 is 45 degrees, and one end of it extends to the upper end of the groove of the grinding disk 5, which can turn the raw materials on the discharge cylinder 6 and the iron cloth filter screen 4 onto the grinding disk 5, improving the grinding effect and preventing raw material adhesion at the same time;

[0048] Principle: During the rotation of the bevel gear disk 7, the diversion scraper 141 and the side wall scraper 142 follow the rotation of the human-shaped mounting column 8 to scrape the raw materials adhered to the side walls of the material distribution cone 51, the discharge cylinder 6 and the iron cloth filter screen 4, and through the bottom side edge of the diversion scraper 141 and the inclination angle of the side wall scraper 142, the adhered raw materials enter the groove of the grinding disk 5, having a good grinding effect on water-based materials with high viscosity.

[0049] Furthermore, as shown in Figure 2 and Figure 8 shown, a screw conveyor rod 15 is rotatably arranged inside the discharge pipe 10. A shaft rod 16 is fixedly arranged inside the screw conveyor rod 15. One end of the shaft rod 16 extends into the inside of the operating table 1. A pump 17 is fixedly arranged at the end of the discharge pipe 10 away from the operating table 1. The other end of the shaft rod 16 is fixedly connected to the input shaft of the pump 17. A servo motor 18 is fixedly installed inside the operating table 1. The output end of the servo motor 18 is fixedly connected to one end of the shaft rod 16. The servo motor 18 is used to drive the screw conveyor rod 15 to work through the shaft rod 16. The pump 17 can provide power for the ground water-based materials, facilitating the connection and transportation to a relatively far storage cylinder;

[0050] Among them, the ground slurry converges through the funnel 2 to the inside of the discharge pipe 10 at the bottom. The servo motor 18 drives the auger conveying rod 15 through the shaft rod 16 to convey the water-based paint. On the one hand, it facilitates the discharge of the water-based paint. On the other hand, it can stir while discharging to prevent the water-based paint from coagulating and generating precipitation. And the auger conveying rod 15 can play a role in forcibly pushing the water-based paint with a relatively high viscosity, thus preventing the discharge port from being blocked;

[0051] Principle: The servo motor 18 drives the auger conveying rod 15 through the shaft rod 16 to convey the water-based paint. While the auger conveying rod 15 stirs the water-based paint, it can drive the pump 17 to extract it. When the pump 17 works, a negative pressure is generated inside the funnel, so that the outside air enters the discharge cylinder 6 from the feed port 11. The air can adsorb the raw material slurry through the iron cloth filter screen 4. On the one hand, it greatly improves the filtration efficiency of the slurry. On the other hand, it can prevent the iron cloth filter screen 4 from being blocked, thus greatly extending the service life of the grinding device.

[0052] At the same time, as Figure 8 shown, the upper end of the discharge cylinder 6 is meshed and connected with a bevel gear 19. The driving rod of the bevel gear 19 extends into the operating platform 1. One end of the shaft rod 16 and the bevel gear 19 located inside the operating platform 1 is fixedly installed with a sprocket 20. A chain 21 is rotatably arranged on the outside of the sprocket 20. The shaft rod 16 and the bevel gear 19 rotate synchronously through the chain 21;

[0053] Among them, through the connection of the chain 21 and the sprocket 20, the shaft rod 16 and the bevel gear 19 can rotate synchronously, which can ensure the coordinated rotation of the bevel gear disc 7 and the operation of the pump 17, and ensure the operation stability and coherence of the whole device. The driving components are arranged inside the operating platform 1, which is convenient for the operator to control and monitor the equipment at the same position. The operator can more conveniently adjust the operating parameters of the equipment, improve the operation efficiency and reduce the setting of the power system, thus saving costs.

[0054] Furthermore, as Figure 1 、 Figure 6 and Figure 8 shown, a U-shaped bracket 22 is fixedly arranged on the outside of the funnel 2. One end of the U-shaped bracket 22 away from the funnel 2 is fixedly installed on the side of the operating platform 1 through screws. A Z-shaped fixing plate 61 is fixedly installed on the side of the discharge cylinder 6. One end of the Z-shaped fixing plate 61 away from the discharge cylinder 6 is fixedly installed on the operating platform 1 through bolts. The driving rod of the bevel gear 19 penetrates through the Z-shaped fixing plate 61 and extends into the operating platform 1. The U-shaped bracket 22 firmly fixes the funnel 2 on the side of the operating platform 1 to prevent the funnel 2 from detaching due to factors such as vibration generated by the equipment operation, affecting the normal production process.

[0055] As Figure 1 -Figure 9 As shown in the figure, the principle of the raw material grinding device for water-based paint production provided in this embodiment is as follows:

[0056] During use, the raw materials enter the discharging cylinder 6 from the feeding port 11 through the feeding guide rail 12. The servo motor 18 is started to drive the auger conveying rod 15 and the pump 17 to work through the shaft rod 16. At the same time, the bevel gear disk 7 is driven to rotate through the sprocket 20 and the chain 21. The bevel gear disk 7 drives the grinding balls 9 to rotate on the grinding disk 5 through a number of human-shaped mounting columns 8. The fine and uniform slurry can enter the interior of the funnel 2 through the iron cloth filter screen 4. The grinding balls 9 roll and grind the raw materials on the grinding disk 5. The ground slurry converges at the bottom of the funnel 2 and is discharged through the discharge pipe 10, thereby greatly improving the production efficiency of water-based paint.
