Description

Technical Field

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

[0002] Polishing machine / sanding machine is a device used to polish, sand and grind the surface of workpiece to meet the design requirements, and is widely used in hardware processing and production. The existing polishing machine used in hardware production generally adopts 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 rotation, 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 polishing machine or 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, it is necessary to purchase multiple polishing machines or sanding machines. In order to improve production efficiency, enterprises can design multiple polishing machines or sanding machines into an automated production line. Polishing machines or sanding machines are generally fixed in the production workshop, which not only takes up space resources, but also needs to deal with the powder and exhaust gas generated by the polishing machine or sanding machine processing, and it is necessary to add a dust collection and degassing mechanism. 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.
