[0002] As consumers' requirements for home quality continue to increase, furniture manufacturers are facing higher production standards and stricter market access conditions. Especially in the board processing link of furniture production, edge banding machines, as one of the key equipment, have a direct impact on the quality and production efficiency of the final product. Although the edge banding machines currently on the market have achieved automated operation, there are still many deficiencies in trimming accuracy and stability. These problems not only restrict the further improvement of production efficiency, but also affect the quality stability of the finished product and limit the expansion of the market.

[0003] At present, the mainstream edge banding machine trimming device on the market usually uses linear bearings plus optical axes to achieve transmission. This design simplifies the mechanical structure to a certain extent and reduces costs. However, this type of transmission method has some limitations: on the one hand, the matching clearance between the linear bearing and the optical axis is often large, which not only increases the lack of rigidity and vibration during the movement, but also leads to a decrease in trimming accuracy; on the other hand, in the high dust environment unique to the edge banding process, the traditional linear bearing plus optical axis combination has poor dust prevention effect, which is easy to cause internal pollution, increase the risk of wear, and shorten the service life.
