AI Technical Summary
In the existing technology, horizontal roller mixers have low pulverization efficiency for block coatings, and block coatings tend to get close to the inner wall of the mixing tank and cannot be fully pulverized, resulting in poor pulverization effect.
A servo motor-driven shaft rotates the grinding wheel and scraper within the filter disc. The grinding wheel grinds and pulverizes the blocky coating, while the scraper prevents the coating at the edges from being uncrushed. Combined with the rotating shaft driving the stirring rod, this achieves better pulverization and mixing.
It improves the crushing effect of block coatings, so that the mixed coatings reach the required particle size, thereby improving work efficiency and reducing energy waste.

Description
Technical Field
[0001] This utility model relates to the technical field of paint mixing devices, specifically a mixing device for crushing blocky paint. Background Technology
[0002] Paint, traditionally known as varnish in China, is a viscous liquid applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to the object. It is usually based on resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared with organic solvents or water. In the production and preparation of paint, a stirring device is needed to crush and stir the blocky paint raw materials before the powdered paint raw materials and appropriate additives can be combined to form varnish.
[0003] A search of the published patent document CN221673937U reveals a mixing device for crushing blocky coatings. This published patent document solves the problem of low efficiency in crushing blocky coatings by existing horizontal roller mixers. However, the published patent document uses rotating crushing blades inside the mixing chamber for crushing and mixing, which makes it impossible for the blocky coatings to reach the required particle size. Furthermore, due to the centrifugal force of the mixing, the blocky coatings tend to stay close to the inner wall of the mixing chamber and cannot be crushed, resulting in poor crushing effect. Utility Model Content
[0004] The purpose of this invention is to provide a stirring device for crushing blocky coatings, which solves the problems mentioned in the background art.
[0005] This application provides a mixing device for crushing blocky coatings, including a crushing and mixing tank. The top of the crushing and mixing tank is provided with a matching tank cover. A filter plate is fixedly installed inside the crushing and mixing tank. A servo motor is fixedly installed in the middle of the top of the tank cover. A rotating shaft is fixedly installed at the output end of the servo motor. Grinding wheels that match the filter plate are rotatably connected to both sides of the rotating shaft. A scraper that matches the filter plate is fixedly installed on the outer wall of the rotating shaft. A circular hole is opened in the middle of the filter plate. The lower end of the rotating shaft passes through the circular hole. The grinding wheels and scrapers are both located inside the filter plate.
[0006] By adopting the above technical solution, the servo motor drives the rotating shaft to rotate, and the rotating shaft drives the grinding wheel and scraper to rotate inside the filter plate. The grinding wheel grinds and crushes the blocky coating, and the crushed coating falls into the bottom of the grinding and mixing tank, so that the mixed coating reaches the required particle size. The scraper scrapes the blocky coating to prevent the blocky coating at the edge of the filter plate from not being ground and crushed, resulting in a better crushing effect.
[0007] Optionally, the grinding and mixing tank is provided with a second rotating shaft inside. A support rod is sleeved on and rotatably connected to the second rotating shaft. The two ends of the support rod are fixedly installed to the inner wall of the grinding and mixing tank. Several stirring rods are fixedly installed on the outer wall of the second rotating shaft. A slot is opened at the bottom of the first rotating shaft. A locking block is fixedly connected to the top of the second rotating shaft. The locking block is adapted to the slot.
[0008] By adopting the above technical solution, when the bucket lid is closed, the card block enters the card slot, which drives the rotating shaft to rotate when grinding and crushing the blocky coating, thus stirring the ground and crushed coating, which improves work efficiency and reduces energy waste.
[0009] Optionally, four support legs are fixedly connected at equal intervals along the outer edge of the bottom of the crushing and mixing tank. The bottom of each support leg has a threaded groove, and a matching threaded shaft is threaded into the inside of the threaded groove. A foot pad is fixedly connected to the lower end of the threaded shaft.
[0010] By adopting the above technical solution, the rotating threaded shaft can be adjusted to its position inside the threaded groove, thereby adjusting the height of each foot pad and making the device suitable for uneven ground.
[0011] Optionally, a feed pipe extends through the lid of the barrel, and a discharge pipe is connected to the bottom of the crushing and mixing barrel, with a gate valve installed on the discharge pipe.
[0012] By adopting the above technical solution, loading and unloading of materials becomes easier.
[0013] Optionally, a number of mounting bolts are threaded through and connected to the outer edge of the top of the crushing and mixing barrel, and the crushing and mixing barrel is connected to the barrel cover by mounting bolts.
[0014] By adopting the above technical solution, it is convenient to install and disassemble the crushing and mixing tank and the tank cover.
[0015] Optionally, the outer wall of the pulverizing and mixing tank is provided with an observation window.
[0016] By adopting the above technical solution, it is convenient to observe the grinding, crushing and mixing of blocky coatings inside the crushing and mixing tank.
[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0018] 1. The technical solution of this application involves conveying blocky coating material onto a filter plate. A servo motor drives a rotating shaft to rotate, which in turn drives a grinding wheel and a scraper to rotate within the filter plate. The grinding wheel grinds and pulverizes the blocky coating material, and the pulverized coating material leaks into the bottom of the grinding and mixing tank, ensuring that the mixed coating material reaches the required particle size. The scraper scrapes off the blocky coating material, preventing any un-ground blocky coating material at the edge of the filter plate from being left unground, resulting in a better pulverization effect.
[0019] 2. In this application, when the lid is closed, the lower end of the first rotating shaft passes through the round hole and approaches the upper end of the second rotating shaft, causing the locking block to enter the slot. This allows the second rotating shaft to rotate while grinding and crushing the blocky coating. The second rotating shaft then rotates the stirring rod, thus stirring the ground and crushed coating. This improves work efficiency and reduces energy waste. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Please see Figure 1-2This utility model provides a technical solution: including a crushing and mixing tank 1, a matching tank cover 2 on the top of the crushing and mixing tank 1, a filter plate 10 fixedly installed inside the crushing and mixing tank 1, a servo motor 3 fixedly installed in the middle of the top of the tank cover 2, a rotating shaft 9 fixedly installed at the output end of the servo motor 3, grinding wheels 11 matching the filter plate 10 rotatably connected to both sides of the rotating shaft 9, and a scraper 12 matching the filter plate 10 fixedly installed on the outer wall of the rotating shaft 9, a round hole 13 opened in the middle of the filter plate 10, the lower end of the rotating shaft 9 passing through the round hole 13, and the grinding wheels 11 and scrapers 12 being inside the filter plate 10;
[0028] In this technical solution, the block coating is conveyed to the filter plate 10, the servo motor 3 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the grinding wheel 11 and scraper 12 to rotate inside the filter plate 10. The grinding wheel 11 grinds and crushes the block coating, and the crushed coating leaks into the bottom of the grinding and mixing tank 1, so that the mixed coating reaches the required particle size. The scraper 12 scrapes the block coating to prevent the block coating at the edge of the filter plate 10 from not being ground and crushed, resulting in a better crushing effect.
[0029] In some technical solutions, such as Figure 2-3 As shown, a second rotating shaft 15 is provided inside the crushing and mixing tank 1. A support rod 14 is sleeved on the second rotating shaft 15 and rotatably connected thereto. The two ends of the support rod 14 are fixedly installed to the inner wall of the crushing and mixing tank 1. Several stirring rods 17 are fixedly installed on the outer wall of the second rotating shaft 15. A slot 18 is provided at the bottom of the first rotating shaft 9. A locking block 16 is fixedly connected to the top of the second rotating shaft 15. The locking block 16 is compatible with the slot 18.
[0030] When in use, after the lid 2 is closed, the lower end of the rotating shaft 9 passes through the round hole 13 and approaches the upper end of the rotating shaft 15, so that the locking block 16 enters the slot 18. This allows the rotating shaft 15 to rotate while grinding and crushing the blocky paint. The rotating shaft 15 then drives the stirring rod 17 to rotate, which in turn stirs the ground and crushed paint, improving work efficiency and reducing energy waste.
[0031] In some technical solutions, such as Figure 1 and Figure 4 As shown, four support legs 6 are fixedly connected at equal intervals along the outer edge of the bottom of the crushing and mixing tank 1. The bottom of the support legs 6 is provided with a threaded groove 19. The threaded groove 19 is connected to a matching threaded shaft 20. The lower end of the threaded shaft 20 is fixedly connected with a foot pad 21.
[0032] In use, the position of the threaded shaft 20 inside the threaded groove 19 can be adjusted by rotating the threaded shaft 20, thereby adjusting the height of each foot pad 21, making the device suitable for uneven ground.
[0033] In some technical solutions, such as Figure 1-2 As shown, a feed pipe 4 runs through the lid 2, and a discharge pipe 5 is connected to the bottom of the crushing and mixing tank 1. A gate valve is installed on the discharge pipe 5.
[0034] During use, the feed pipe 4 and discharge pipe 5 facilitate loading and unloading of materials.
[0035] In some technical solutions, such as Figure 1-2 As shown, several mounting bolts 8 are threaded through and connected to the outer edge of the top of the crushing and mixing tank 1, and the crushing and mixing tank 1 and the tank cover 2 are connected by the mounting bolts 8.
[0036] During use, the installation bolts 8 facilitate the installation and disassembly of the crushing and mixing tank 1 and the tank cover 2.
[0037] In some technical solutions, such as Figure 1-2 As shown, the outer wall of the crushing and mixing tank 1 is provided with an observation window 7.
[0038] During use, the grinding, crushing, and mixing of the blocky coating inside the crushing and mixing tank 1 can be easily observed through the observation window 7.
[0039] Working principle: During operation, the required granular coating material is fed into the grinding and mixing tank 1 through the feed pipe 4. The granular coating material falls onto the filter plate 10. The servo motor 3 drives the rotating shaft 9 to rotate, which in turn drives the grinding wheel 11 and scraper 12 to rotate within the filter plate 10. The grinding wheel 11 grinds and pulverizes the granular coating material, which then falls into the bottom of the grinding and mixing tank 1, ensuring that the mixed coating material reaches the required particle size. The scraper 12 scrapes away the granular coating material, preventing it from falling into the filter plate 10. The lumpy coating at the edge is not ground and crushed, resulting in better crushing effect. When the lid 2 is closed, the lower end of the rotating shaft 9 passes through the round hole 13 and approaches the upper end of the rotating shaft 15, causing the locking block 16 to enter the locking groove 18. This allows the rotating shaft 15 to rotate while grinding and crushing the lumpy coating. The rotating shaft 15 then drives the stirring rod 17 to rotate, thus stirring the ground and crushed coating. This improves work efficiency and reduces energy waste. Finally, the ground and mixed coating is discharged through the discharge pipe 5.
