Description

Technical Field

[0002] Boards are generally used to make furniture. They need to be wrapped with edge banding strips around the edges to improve the regularity and aesthetics. The edge banding strips are usually wound on a shaft to form a feed reel. When the boards are piled up for edge banding, the edge banding strips are fed to the edge banding machine through the feed reel.

[0003] When the existing edge banding strip feeding device is transmitting the edge banding strip to the edge banding machine, due to the large inertia of the feeding reel, it usually releases too much edge banding strip, causing the edge banding strip between the feeding reel and the reversing roller to warp, which cannot meet the edge banding requirements of the edge banding machine, and will cause the equipment to be messy and affect the operational safety to a certain extent.

[0004] Therefore, it is necessary to design an edge banding strip feeding device so that the edge banding strip can be tensioned to avoid the above disadvantages. Utility Model Content
