Description

Technical Field

[0001] This utility model relates to the field of floor grinding and polishing technology, specifically to a floor grinding and polishing device. Background Technology

[0002] In the field of flooring construction, grinding and polishing are key processes for improving the flatness, smoothness, and durability of flooring, and are widely used in the surface treatment of various types of flooring, such as concrete, stone, and epoxy. Floor grinding and polishing equipment removes surface imperfections, adjusts flatness, and creates a mirror effect through contact friction between the grinding disc or grinding head and the floor surface. The quality of its operation directly affects the final appearance and service life of the flooring. In the grinding and polishing process, grinding pressure is the core parameter that determines the efficiency and effect of the operation. Different types of flooring materials (such as high-hardness granite, medium-hardness concrete, and softer epoxy coatings) and different polishing stages have significantly different requirements for grinding pressure. For example, the rough grinding stage requires higher pressure to quickly remove surface protrusions and impurities, while the fine grinding stage requires lower and more stable pressure to avoid over-grinding and ensure uniform surface finish. In existing technologies, the pressure adjustment method of floor grinding and polishing devices mostly adopts a mechanical counterweight structure. By adding or removing counterweights, the pressure of the grinding head on the floor is changed. However, during the pressure adjustment process, the weight of the counterweights is generally fixed. Therefore, the adjustment accuracy of the grinding disc pressure affects the grinding effect of the grinding disc on the floor. Utility Model Content

Specifically, the operation of the second motor 23 can drive the driving prism 22 to rotate. At the same time, the sliding cooperation between the driving prism 22 and the second driving port 21 drives the second gear 19 to rotate. Then, the meshing of the second gear 19 with the first gear 18 drives the first gear 18, the support column, and the support disk 9 to rotate. This facilitates the rotation of the grinding disk 10 through the cooperation between the positioning column 11 and the positioning port.

[0024] Reference Figures 2-4 The dust collection mechanism includes a dust collection box 24, a dust collection pipe 26, a dust collection port 27, and a fan 28.

[0025] It should also be noted that a storage battery is installed on the support base 1, and the storage battery is electrically connected to the first motor 17, the second motor 23 and the fan 28 respectively.

[0026] In this embodiment, during use, the operator controls the first motor 17 to operate. The operation of the first motor 17 drives the threaded rod 16 to rotate. Simultaneously, the threaded engagement between the threaded rod 16 and the first housing 15 causes the first housing 15, the support column, and the support plate 9 to move. During the movement of the support plate 9, pressure can be applied to the grinding plate 10 by the support spring 13. Thus, the operation of the first motor 17 enables continuous fine adjustment of the grinding pressure of the grinding plate 10. Afterward, the operator controls the second motor 23 to operate. The operation of the second motor 23 drives the drive prism 22 to rotate. Simultaneously, the sliding between the drive prism 22 and the second drive port 21... The second gear 19 is driven to rotate, and the meshing of the second gear 19 with the first gear 18 drives the first gear 18, the support column, and the support plate 9 to rotate. This facilitates the rotation of the grinding plate 10 through the engagement of the positioning column 11 and the positioning port. Then, the operator pushes the handle 5 to grind and polish the floor. During the polishing process, the operator controls the blower 28 to work. The operation of the blower 28 can generate negative pressure in the dust collection box 24, so that the dust generated during the grinding process can enter the dust collection box 24 through the gap between the grinding plate 10 and the fixed cover 7, the dust collection port 27, and the dust collection pipe 26 for collection, thereby preventing the spread of dust.
