Description

Technical Field

[0001] The invention relates to the technical field of grinding, in particular to a raw material grinding device for producing water-based paint. Background Art

[0002] Water-based paint refers to paint that uses water as a solvent or dispersion medium. It has the characteristics of low volatility, non-toxicity, odorlessness, and easy cleaning. However, due to the different textures of its pigments and base materials, it is prone to problems such as stickiness, precipitation, and agglomeration. Through grinding, the pigment particles can be dispersed in the paint matrix to achieve a uniform dispersion effect, which helps to improve the stability and uniformity of the paint and prevent precipitation and stratification during storage and use, thereby ensuring the stability and consistency of the coating effect.

[0003] In the prior art, water-based coatings are usually ground using vertical grinders and horizontal grinders. Both grind the material through friction and collision between grinding media. After a certain residence time, a slurry with a particle size distribution that meets the requirements is obtained. In actual use, when the two grinders are stopped, the grinding media is at the bottom of the grinding cylinder. When the machine is started, the stirring shaft and the beads produce strong friction. Since the grinding beads are too concentrated, it is easy to cause bead breakage. In addition, the grinding process needs to be carried out under sealed conditions, which is not convenient for unloading.

[0004] Therefore, there is an urgent need to improve the raw material grinding device used in the production of water-based paint to solve the above-mentioned problems. Summary of the invention

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

[0020] 1. The present invention can drive the grinding balls to rotate on the grinding disc through a plurality of human-shaped mounting columns via a conical gear disc, and fine and uniform slurry can enter the interior of the funnel through an iron cloth filter and be discharged through a discharge pipe, which changes the traditional grinding method using shear force of grinding beads. The grinding balls roll and grind the raw materials on a fixed track, thereby greatly reducing the probability of the grinding balls breaking, and realizing the function of synchronous feeding and discharging through a feed port and a discharge pipe, thereby greatly improving the production efficiency of water-based coatings.

[0021] 2. In the present invention, after the raw materials enter the discharge barrel through the feed port, they first contact the top of the dividing cone. The raw materials flow along the side wall of the dividing cone to the bottom of several grinding balls, which can make the material discharge more uniform. During the rotation of the conical toothed disc, the grinding balls are rolled along the grooves inside the dividing disc through the plug-in rods and the plug-in piles. Under the cyclic rolling action of the grinding balls, the raw materials become delicate and uniform, thereby having a better grinding effect.

[0022] 3. During the rotation of the bevel toothed disc of the present invention, the guide scraper and the side wall scraper follow the rotation of the human-shaped mounting column 8 to scrape the raw materials adhered to the dividing cone, the discharge barrel and the side wall of the iron cloth filter, and the adhered raw materials are allowed to enter the groove of the grinding disc through the bottom edge of the guide scraper and the inclination angle of the side wall scraper, which has a good grinding effect for water-based materials with high viscosity.

[0023] 4. The ground slurry is gathered into the inside of the discharge pipe at the bottom through the funnel. The servo motor drives the auger conveying rod through the shaft to convey the water-based paint. On the one hand, it is convenient for the discharge of the water-based paint. On the other hand, it can be stirred while discharging to prevent the water-based paint from condensing and forming precipitation. The auger conveying rod can force the water-based paint with higher viscosity to push, thereby preventing the discharge port from being blocked.

[0024] 5. The servo motor of the present invention conveys the water-based paint through a shaft driving the auger conveying rod. The auger conveying rod can drive the pump to extract the water-based paint while stirring the water-based paint. The operation of the pump generates negative pressure inside the funnel, so that the outside air enters the discharge barrel from the feed port. The air can adsorb the raw material slurry through the iron cloth filter. On the one hand, the filtration efficiency of the slurry is greatly improved, and on the other hand, the iron cloth filter can be prevented from being blocked, thereby greatly extending the service life of the grinding device.

[0025] 6. The present invention connects the chain and the sprocket so that the shaft and the bevel gear can rotate synchronously, which can ensure that the rotation of the bevel gear plate is coordinated with the work, and ensure the operating stability and continuity of the entire device. The driving component is arranged inside the operating table, 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 operating efficiency, and reduce the setting of the power system, thereby saving costs.

[0037] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0038] like Figure 1 - Fig. 9 As 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 on the upper end of the operating table 1, a flange 3 is fixedly installed on the upper end of the funnel 2, an iron cloth filter 4 is fixedly installed on the bottom side of the flange 3, a grinding disc 5 is fixedly installed on the bottom end of the iron cloth filter 4, and the iron cloth filter 4 and the grinding disc 5 are both arranged inside the funnel 2; a discharge barrel 6 is fixedly installed on the upper end of the flange 3, a bevel gear disc 7 is rotatably arranged inside the discharge barrel 6, a plurality of evenly distributed human-shaped mounting columns 8 are fixedly installed on the bottom side of the bevel gear disc 7, a grinding ball 9 is rotatably arranged on the bottom end of the human-shaped mounting column 8, the bottom side of the grinding ball 9 is in contact with the inner side of the grinding disc 5, and the grinding ball 9 is rotatably arranged inside the iron cloth filter 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 can support the funnel 2 and the grinding disc 5 on the other hand for easy transportation. The bevel gear disc 7 drives the grinding balls 9 to rotate on the grinding disc 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 4, which changes the traditional grinding method through the shear force of the grinding beads. The grinding balls 9 roll and grind the raw materials on the fixed track, so the probability of the grinding balls breaking can be greatly reduced;

[0040] A discharge pipe 10 is fixedly provided at the bottom end of the funnel 2, the interior of the discharge pipe 10 is connected to the interior of the funnel 2, a feed port 11 is provided inside the bevel gear disc 7, the feed port 11 is arranged above the iron cloth filter 4, a feed guide rail 12 is fixedly installed at the upper end of the operating table 1, and the bottom end of the feed guide rail 12 extends above the feed port 11;

[0041] Among them, the raw materials enter the discharge barrel 6 from the feed port 11 through the discharge guide rail 12, and the discharge pipe 10 is used for discharging. The ground slurry gathers at the bottom of the funnel 2 and is discharged through the discharge pipe 10. The feed port 11 and the discharge pipe 10 realize the function of synchronous feeding and discharging, thereby greatly improving the production efficiency of water-based coatings.

[0042] Further, such as Figure 5 and Fig. 9 As shown, a material dividing cone 51 is fixedly provided on the inner top side surface of the grinding disc 5, and the material dividing cone 51 corresponds to the feed port 11. A bevel groove 52 is provided on the edge of the grinding disc 5, and the bevel groove 52 corresponds to the inner side wall of the funnel 2. An arc-shaped protective plate 13 is fixedly installed on the bottom end of the human-shaped mounting column 8. The grinding ball 9 is rotatably arranged inside the arc-shaped protective plate 13. Scraping mechanisms 14 are fixedly installed on both ends of the arc-shaped protective plate 13. A plug-in rod 131 is fixedly installed on the bottom side of the arc-shaped protective plate 13. The plug-in rod 131 extends to the inside of the grinding ball 9. A plug-in pile 91 is rotatably arranged inside the grinding ball 9. A spline 132 is fixedly arranged on the end of the plug-in rod 131 away from the grinding ball 9, and the spline 132 corresponds to the plug-in pile 91.

[0043] Wherein; the spline 132 is used to connect the plug rod 131 and the plug pile 91. During the rotation of the bevel gear plate 7, the plug rod 131 is in a horizontal state, and several plug rods 131 rotate with the perpendicular bisector of the cross section of the material dividing cone 51 as the axis. At this time, the plug rod 131 is rotatably connected with the grinding ball 9 through the plug pile 91, so that the grinding ball 9 can roll along the groove of the grinding disk 5, and the arc-shaped protective plate 13 can scrape the raw materials adhered to the surface of the grinding ball 9 to prevent the grinding ball 9 from becoming larger and affecting the grinding effect;

[0044] Principle: After the raw material enters the discharge barrel 6 through the feed port 11, it first contacts the top of the dividing cone 51. The raw material flows along the side wall of the dividing cone 51 to the bottom of several grinding balls 9, which can make the discharge more uniform. During the rotation of the bevel gear disk 7, the grinding balls 9 are rolled along the grooves inside the dividing disk 5 through the plug-in rods 131 and the plug-in piles 91. Under the cyclic rolling action of the grinding balls 9, the raw material becomes delicate and uniform, and has a better grinding effect. Therefore, the water-based paint can meet the product's requirements for fineness. Through the extrusion of the grinding balls 9 and the contact with the iron cloth filter 4, the uniform slurry flows to the inside of the funnel 2 through the bevel groove 52, which is convenient for collection.

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

[0046] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the scraping mechanism 14 includes a guide scraper 141 and a side wall scraper 142. The bottom side of the guide scraper 141 contacts the side of the material distribution cone 51. One end of the guide scraper 141 extends to the bottom side of the grinding ball 9. One side of the side wall scraper 142 contacts the inner side wall of the discharge barrel 6 and the iron cloth filter 4. During the rotation of the bevel toothed disc 7, the side wall scraper 142 does not contact 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 protective plate 13 can scrape the raw materials adhered to the surface of the grinding ball 9 to prevent the grinding ball 9 from becoming larger and affecting the grinding effect. The guide scraper 141 can scrape the raw materials adhered to the side wall of the material distribution cone 51. The bevel toothed disc 7 rotates clockwise, and the raw materials can flow along the bottom edge of the guide scraper 141 to the bottom of the grinding ball 9. The side wall scraper 142 can scrape the raw materials adhered to the inner wall of the discharge barrel 6 and the iron cloth filter 4. The inclination angle of the side wall scraper 142 is 45 degrees, and one end of the side wall scraper 142 extends to the upper end of the groove of the grinding disc 5, so that the raw materials on the discharge barrel 6 and the iron cloth filter 4 can be turned over to the grinding disc 5, which can improve the grinding effect and prevent the raw materials from adhering.

[0048] Principle: During the rotation of the bevel toothed disc 7, the guide 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 dividing cone 51, the discharge barrel 6 and the side wall of the iron cloth filter 4, and the adhered raw materials are allowed to enter the groove of the grinding disc 5 through the bottom edge of the guide scraper 141 and the inclination angle of the side wall scraper 142, which has a good grinding effect for water-based materials with high viscosity.

[0049] Furthermore, Figure 2 and Figure 8 As shown, an auger conveying rod 15 is rotatably provided inside the discharge pipe 10, and a shaft 16 is fixedly provided inside the auger conveying rod 15, one end of the shaft 16 extends to the inside of the operating table 1, and a pump 17 is fixedly provided at one end of the discharge pipe 10 away from the operating table 1, and the other end of the shaft 16 is fixedly connected to the input shaft of the pump 17, and a servo motor 18 is fixedly installed inside the operating table 1, and the output end of the servo motor 18 is fixedly connected to one end of the shaft 16, and the servo motor 18 is used to drive the auger conveying rod 15 to work through the shaft 16, and the pump 17 can provide power to the ground water-based material, so as to facilitate the connection and conveying to a storage cylinder farther away;

[0050] The ground slurry is gathered into the discharge pipe 10 at the bottom through the funnel 2, and the servo motor 18 drives the auger conveying rod 15 through the shaft 16 to convey the water-based paint, which is convenient for the discharge of the water-based paint on the one hand, and can be stirred while discharging to prevent the water-based paint from condensing and forming precipitation, and the auger conveying rod 15 can have a forced pushing effect on the water-based paint with high viscosity, thereby preventing the discharge port from being blocked;

[0051] Principle: The servo motor 18 drives the auger conveying rod 15 to convey the water-based paint through the shaft 16. The auger conveying rod 15 can drive the pump 17 to extract the water-based paint while stirring the water-based paint. The operation of the pump 17 generates negative pressure inside the funnel, so that the outside air enters the discharge barrel 6 from the feed port 11. The air can adsorb the raw material slurry through the iron cloth filter 4. On the one hand, the filtration efficiency of the slurry is greatly improved, and on the other hand, the iron cloth filter 4 can be prevented from being blocked, thereby greatly extending the service life of the grinding device.

[0052] At the same time, if Figure 8 As shown, the upper end of the discharge barrel 6 is meshedly connected with a bevel gear 19, the driving rod of the bevel gear 19 extends into the interior of the operating table 1, and a sprocket 20 is fixedly installed at one end of the shaft 16 and the bevel gear 19 located inside the operating table 1, and a chain 21 is rotatably arranged on the outer side of the sprocket 20, and the shaft 16 and the bevel gear 19 rotate synchronously through the chain 21;

[0053] Among them, through the connection between the chain 21 and the sprocket 20, the shaft 16 and the bevel gear 19 can rotate synchronously, so as to ensure that the rotation of the bevel gear plate 7 is coordinated with the operation of the pump 17, and the operating stability and continuity of the entire device are guaranteed. The driving component is arranged inside the operating table 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 operating efficiency, and reduce the setting of the power system, thereby saving costs.

[0054] Further, if Figure 1 , Figure 6 and Figure 8 As shown, a U-shaped bracket 22 is fixedly provided on the outer side of the funnel 2, and the end of the U-shaped bracket 22 away from the funnel 2 is fixedly installed on the side of the operating table 1 by screws, and a Z-shaped fixing plate 61 is fixedly installed on the side of the discharge barrel 6, and the end of the Z-shaped fixing plate 61 away from the discharge barrel 6 is fixedly installed on the operating table 1 by bolts, and the driving rod of the bevel gear 19 passes through the Z-shaped fixing plate 61 and extends to the inside of the operating table 1. The U-shaped bracket 22 firmly fixes the funnel 2 on the side of the operating table 1 to prevent the funnel 2 from being detached due to factors such as vibration generated by the operation of the equipment, thereby affecting the normal production process.

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

[0056] When in use, the raw material enters the discharge barrel 6 from the feed port 11 through the discharge guide rail 12, and the servo motor 18 is started to drive the auger conveying rod 15 and the pump 17 to work through the shaft 16. At the same time, the bevel gear plate 7 is driven to rotate through the sprocket 20 and the chain 21. The bevel gear plate 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 4, and the grinding balls 9 roll and grind the raw materials on the grinding disk 5. The ground slurry gathers 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.

[0057] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
