Description

Technical Field

[0001] The present application relates to the technical field of home furnishing board processing, and particularly relates to a double-headed sponge sanding device with good sanding effect. Background Art

[0002] In the current furniture processing industry, surface sanding treatment is a crucial link, which directly affects the appearance quality, service life and market acceptance of products. As a commonly used sanding material, sponge sand is favored for its softness, wear resistance and good adsorption.

[0003] Traditional sponge sanding equipment generally adopts a single-headed design. In practical applications, first, the workpiece is steadily placed on the support table and fixed by appropriate jigs to ensure stability during the sanding process. Subsequently, the support table is smoothly pushed under the sponge sand, and then the equipment is started. At this time, the sponge sand finely sands the top side of the workpiece with appropriate force and speed. After one side of the sanding is completed, the user takes out the workpiece, flips it to the other side, and then places the workpiece on the support table again, repeating the previous process until the back side of the workpiece is also sanded.

[0004] However, in the actual use process, since the workpiece needs to be manually taken out, flipped, and placed and fixed again after each sanding, this repeated operation is time-consuming and laborious, reducing the sanding efficiency of the device. Summary of the Invention
