Description

technical field [0001] The invention relates to an automatic grinding machine for sandpaper, in particular to an automatic replacement device for sandpaper. Background technique [0002] The automatic sandpaper grinding machine is a kind of equipment that uses sandpaper to automatically polish and polish the mold. It generally includes a mold core, sandpaper pasted on the mold core, and a mechanical arm that drives the movement of the mold core. Wherein, since the sandpaper is constantly worn during the grinding and polishing process, it is necessary to regularly replace the sandpaper. Specifically, a mold core is installed in the chuck of the manipulator type pneumatic grinder, and then a layer of sandpaper is pasted with glue on the surface of the mold core. After the sandpaper is worn for a period of time, it is necessary to tear off the old sandpaper and paste new sandpaper. Since the sandpaper replacement operation involves removing the old sandpaper and pasting the n...

AI Technical Summary

Problems solved by technology

Since the sandpaper replacement operation involves removing the old sandpaper and pasting the new sandpaper on the cylindrical mold core, the process is relatively complicated, and it is difficult to realize the automatic replacement and pasting by manipulators or other automatic devices. Therefore, the existing sandpaper replacement operation It is all done manually, and there are problems such as low work efficiency, laborious work, and poor safety in the work.
