Description

Technical Field

[0001] The invention relates to the technical field of plate processing, in particular to a surface treatment device for producing and processing laminated wood. Background Art

[0002] Dyeing the surface of wood is a processing method to protect the wood during long-term use. In the production of insulating components of oil-immersed transformers and mutual inductors, insulating cardboard, glass cloth board and electrical laminated wood are mostly used. Since insulating cardboard and glass cloth board are expensive, difficult to process and cause great pollution, electrical laminated wood is currently used as raw material for production. Sanding is a key step in the production of laminated wood. It is usually carried out after the laminate is produced. The purpose of sanding is to make the surface of the wooden laminate more flat and smooth, increase the texture of the wood, and ensure that there are no rough parts or protruding particles on the surface of the laminate.

[0003] In the prior art, in order to improve the grinding efficiency of the laminate, a CNC machining table equipped with a grinding device is usually used to grind the laminate. During grinding, the grinding disc is driven to rotate at high speed by a driving component inside the grinding device, and the high-speed rotating grinding disc contacts the surface of the laminate to grind the laminate.

[0004] Moreover, in order to prevent the dust generated by grinding from flying around and prevent the impact of reduced environmental quality on grinding efficiency, many grinding equipment often add dust collection components to the grinding equipment. The air flow is used to collect the dust from the gap between the grinding disc and the shell inside the component, making the grinding process faster and more efficient. However, since the grinding disc of the grinding equipment occupies a large area, the dust near the center of the grinding disc is not collected well during dust collection.
