Description

Technical Field

[0001] The present invention relates to the technical field of polishing equipment, and in particular to movable polishing production equipment. Background Art

[0002] Polishing machines are used to polish, sand and grind the surface of workpieces to meet the design requirements. They are widely used in hardware processing and production. Existing polishing machines used in hardware production generally use a rotating die frame and a polishing head feeding structure. The rotating die frame is provided with a negative pressure adsorption channel. The workpiece is placed on the rotating die frame and fixed through the negative pressure adsorption channel. When working, the rotating die frame drives the workpiece to rotate, and the sanding head performs sanding on the workpiece.

[0003] When an enterprise wants to perform sanding processing on hardware products, it needs to purchase a sanding machine; most hardware products need to go through multiple processes such as rough processing and fine processing for surface treatment. At this time, multiple sanding machines need to be purchased. In order to improve production efficiency, enterprises can design multiple sanding machines into automated production lines. Sanding machines are generally fixed in production workshops, which not only take up space resources, but also need to deal with the powder and exhaust gas generated by sanding machine processing, and need to add dust collection and degassing mechanisms. When the production line needs to be replaced or moved based on the production plan of the enterprise, a lot of manpower and material resources will be consumed. The type or quantity of hardware products produced is affected by the terminal market. When the terminal market is good, the enterprise will increase production capacity, and vice versa. For enterprises, if the manpower and material resources consumed by production equipment can be reduced and the scalability and mobility of production equipment can be improved, the cost burden of the enterprise will inevitably be reduced and the competitiveness of the enterprise can be improved.
