AI Technical Summary

Technical Problem

Existing composite mesh sponge abrasive blocks need to be discarded after frequent use as the abrasive layer wears down, resulting in low utilization of the sponge itself and making it unsuitable for abrasion needs of different sizes and large areas.

Method used

The design incorporates multiple stepped thinning of the sponge body, with ventilation holes, magnetic blocks, and slots. The sponge body is connected to the sanding layer via adhesive, and the magnetic blocks are connected to the magnetic slots. The sponge body can be flipped over to use the unworn side, and the ventilation holes allow dust and heat to escape.

Benefits of technology

It improves material utilization, adapts to different sizes and large-area grinding, extends service life, enhances stability and comfort, and improves grinding efficiency.

Abstract

The utility model relates to sponge sand block technical field, and disclose a kind of composite grid sponge sand block, including the multiple sponge body of being sequentially arranged from top to bottom, the thickness of each sponge body is ladder type drop from top to bottom, the right side of the sponge body is provided with bearing cloth.This kind of composite grid sponge sand block, by setting up multiple sponge body and making the size of sponge body ladder type change, when facing different size inner recess type polishing environment, the appropriate sponge body can be selected according to the size of groove and inserted into groove to carry out accurate polishing, when facing large-area polishing environment, expand sponge body, can increase the use area of sanding layer, to improve polishing efficiency, when the sanding layer of one side of sponge body is lost due to wear, the sponge body can be turned over to use other un-worn side, prolong the overall service life, improve material utilization, to realize the advantages of wide use scene, high material utilization.
