Description
Technical Field
[0001] This utility model relates to the field of coating production technology, and in particular to a grinding mechanism for a horizontal sand mill for coatings. Background Technology
[0002] Paint, also known as coating, is a material that is applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to it. It is usually composed of resin, oil, or emulsion as the main components, with or without pigments, fillers, etc., and is formulated using organic solvents or water as a dispersion medium.
[0003] In existing technologies, large particles of coating raw materials usually need to be ground and crushed to avoid the large particles affecting their subsequent use. Horizontal sand mills are often used for grinding during the grinding process. However, when the coating is being ground, the inner wall of the grinding cylinder generates a lot of heat due to the intense friction between the coating and the grinding media, which causes the temperature inside the grinding cylinder to rise, resulting in the waste of coating through volatilization.
[0004] Therefore, to address the problem that the inner wall of the existing grinding cylinder generates a large amount of heat under intense friction between the coating and the grinding media, leading to an increase in the internal temperature of the grinding cylinder, a grinding mechanism for a coating horizontal sand mill that solves the above problem is needed. Utility Model Content

The mechanism involves starting a fan to dissipate heat from the heat dissipation pipes. The cooled liquid, after heat dissipation, re-enters the heat absorption pipe through a first circulation pipe, thus achieving circulating heat dissipation and preventing the internal temperature of the grinding cylinder from rising, which could lead to coating evaporation and waste.

[0030] Example 1: Refer to Figures 1-3A grinding mechanism for a horizontal coating sand mill includes a base plate 1, a grinding box 2 fixedly connected to the top of the base plate 1, a grinding roller 3 rotatably connected to the inner wall of the grinding box 2, a first support plate 4 fixedly connected to the left end of the top of the base plate 1, a first motor 5 fixedly connected to the front side of the left end of the first support plate 4, a first rotating shaft 6 fixedly connected to the drive end of the first motor 5, a drive gear 7 fixedly connected to the right end of the first rotating shaft 6, a driven gear 8 fixedly connected to the outer wall of the left end of the grinding roller 3, the driven gear 8 meshing with the drive gear 7, a second support plate 9 fixedly connected to the right side of the top of the base plate 1, a heat absorption pipe 11 fixedly connected to the inner wall of the grinding roller 3, and one end of the inner wall of the first support plate 4 and the second support plate 9 fixedly connected to the grinding roller 3. A connector 10 is fixedly connected. The left and right ends of the heat absorption pipe 11 are rotatably connected to the inner wall of the connector 10. A second circulation pipe 13 is fixedly connected to the outer wall of the left connector 10, and a first circulation pipe 12 is fixedly connected to the outer wall of the right connector 10. A heat dissipation box 14 is fixedly connected to the rear side of the top of the base plate 1. A heat dissipation pipe 15 is fixedly connected to the rear side of the inner wall of the heat dissipation box 14. A fan 17 is fixedly connected to the front side of the inner wall of the heat dissipation box 14. A water pump 16 is fixedly connected to the left end of the heat dissipation pipe 15. The right end of the water pump 16 is fixedly connected to the left end of the heat dissipation box 14. The other end of the second circulation pipe 13 is fixedly connected to the left end of the water pump 16. The other end of the first circulation pipe 12 is fixedly connected to the right end of the heat dissipation pipe 15.
[0031] Specifically, the first motor 5 is started, which drives the first rotating shaft 6 to rotate, thereby driving the drive gear 7 to rotate. The drive gear 7 meshes with the driven gear 8, causing the driven gear 8 to rotate, thus driving the grinding roller 3 to grind the paint raw material. During the grinding process, the coolant in the heat-absorbing pipe 11 on the inner wall of the grinding roller 3 absorbs the heat generated by grinding, and this coolant containing heat then flows into the second circulation pipe 13 through the heat-absorbing pipe 11. Under the action of the water pump 16, the coolant containing heat is transported to the heat dissipation pipe 15 in the heat dissipation box 14. At this time, the fan 17 starts to work to cool the heat dissipation pipe 15. The cooled coolant returns to the heat-absorbing pipe 11 through the first circulation pipe 12, forming a circulating heat dissipation system. This system effectively prevents the temperature inside the grinding cylinder from rising, avoids paint evaporation and waste, and has an interface on the outer wall of the second circulation pipe 13 for replenishing coolant, which facilitates the replenishment of coolant. After grinding is completed, the paint is discharged through the discharge pipe 24, thus completing the entire paint grinding process.
[0032] Example 2: Refer to Figure 1 and Figure 4A feed box 18 is fixedly connected to the top left of the grinding box 2. A connecting plate 20 is fixedly connected to the top of the feed box 18. A second motor 21 is fixedly connected to the top of the connecting plate 20. A second rotating shaft 22 is fixedly connected to the drive end of the second motor 21. A crushing blade 23 is fixedly connected to the outer wall of the bottom end of the second rotating shaft 22. The outer wall of the crushing blade 23 is set on the inner wall of the feed pipe 19. A feed pipe 19 is fixedly connected to the bottom end of the feed box 18. The bottom end of the feed pipe 19 is fixedly connected to the top left of the grinding box 2. A discharge pipe 24 is fixedly connected to the front right of the bottom plate 1.
[0033] Specifically, during operation, the paint raw material is introduced through the feed box 18. Then, the second motor 21 is started, and its drive end causes the second rotating shaft 22 to rotate. The second rotating shaft 22 drives the crushing blades 23 to crush the paint raw material, ensuring that there are no large particles in the material to avoid affecting the subsequent grinding effect or causing blockage of the feed pipe 19. The crushed paint raw material then enters the grinding chamber 2 through the feed pipe 19.
[0034] Working principle: During use, the paint raw material enters through the feed box 18, the second motor 21 is started, the drive end of the second motor 21 drives the second rotating shaft 22 to rotate, the second rotating shaft 22 drives the crushing blades 23 to crush the paint raw material, so as to avoid the presence of large particles in the paint raw material affecting the subsequent grinding effect and clogging the feed pipe 19. The crushed paint raw material enters the grinding box 2 through the feed pipe 19.
[0035] Simultaneously, the first motor 5 is started, and the drive end of the first motor 5 drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the drive gear 7 to rotate, and the drive gear 7 drives the driven gear 8 to rotate. The driven gear 8 drives the grinding roller 3 to grind the paint raw material. During the grinding process, the coolant in the heat-absorbing pipe 11 on the inner wall of the grinding roller 3 absorbs the heat generated by grinding. The coolant that has absorbed the heat enters the second circulation pipe 13 through the heat-absorbing pipe 11, and then enters the heat dissipation pipe 15 in the heat dissipation box 14 through the action of the water pump 16. At this time, the fan 17 is started, and the fan 17 dissipates heat from the heat dissipation pipe 15. The coolant after heat dissipation re-enters the heat-absorbing pipe 11 through the first circulation pipe 12, thereby achieving circulating heat dissipation and avoiding the situation where the temperature inside the grinding cylinder rises, causing paint to evaporate and be wasted. In addition, an interface for replenishing coolant is provided on the outer wall of the second circulation pipe 13, which can easily replenish coolant. The paint after grinding is discharged through the discharge pipe 24, thus completing the entire paint grinding process.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
