Description

Technical Field

[0001] The utility model relates to the field of rubber roller production, in particular to a grinding device with an embracing dust suction mechanism. Background Art

[0002] Rubber rollers, also known as rubber rollers, are roller-shaped products made of polymer materials such as rubber or plastic. They usually have a metal or other material as the core, and the outer layer is covered with rubber and made through a vulcanization process. They are widely used in various industrial production processes, such as printing, papermaking, leather, textiles, metallurgy, plastic processing and other industries. The production steps of rubber rollers are mainly: roller core processing, rubber mixing, rubber covering, vulcanization treatment, roller surface grinding, and dynamic and static balance detection; among them, during the rubber grinding process, the grinding wheel will remove the uneven parts, burrs, bubbles and other defects that may exist on the surface of the rubber roller to improve its surface quality.

[0003] With respect to the above-mentioned related technologies, the inventors found that since the surface of the rubber roller is covered with rubber, during the grinding process, the rubber is affected by the external grinding wheel or grinding wheel and will produce debris, and some grinding devices do not have the chip removal function or only have a dust suction structure installed in the grinding wheel shell. A large amount of rubber waste chips are still left on the roller surface and the grinder. The waste chips accumulated on the surface of the rubber roller will change its grinding state and form an uneven covering layer, resulting in a decrease in the quality of the grinding surface and affecting the final quality of the product. At the same time, the staff are required to frequently clean the grinder, reducing the grinding efficiency. Utility Model Content
