Technical Field

[0001] The present invention relates to the technical field of refrigerator bottom plate processing, and particularly to a grinding device for the production and processing of refrigerator bottom plates. Background Art

[0002] As an important part of the refrigerator, the refrigerator bottom plate undertakes the functions of supporting the internal structure of the refrigerator and placing important components such as compressors. With the continuous development of refrigerator technology, the performance requirements for the strength, stability, heat insulation, etc. of the refrigerator bottom plate are also increasing day by day. In the early days, simple metal plates were mostly used for refrigerator bottom plates. With the improvement of consumers' requirements for the quality and performance of refrigerators, great improvements have been made in the material selection and structural design of the current refrigerator bottom plates.

[0003] With the improvement of people's living standards, the demand for refrigerators is constantly increasing, and the scale of the refrigerator manufacturing industry is constantly expanding. Consumers' requirements for the quality of refrigerators are also getting higher and higher, including the appearance quality and performance of the refrigerator bottom plate. During the production process of the refrigerator bottom plate, there may be uneven surfaces, such as stamping marks, welding protrusions, etc. Using a grinding device can grind these uneven places to make the surface of the bottom plate reach a high level of flatness, which is convenient for subsequent assembly and use.

[0004] At the same time, the grinding device can make the surface of the refrigerator bottom plate smoother and reduce the surface roughness. This not only helps to improve the appearance quality of the refrigerator, making the refrigerator look more beautiful, but also reduces the adhesion of dust, dirt, etc. on the surface of the bottom plate, which is convenient for daily cleaning and maintenance.

[0005] Regarding the above related technologies, the inventor believes that there are the following defects: When the existing technology continuously grinds the refrigerator bottom plate for a long time, the abrasive belt frequently rubs against the surface of the bottom plate, resulting in relatively fast wear of the abrasive belt. The abrasive belt needs to be replaced regularly. When replacing the abrasive belt, engineers need to use tools to disassemble the screws, and the operation is relatively cumbersome. Summary of the Invention
