Description

TECHNICAL FIELD

[0001] The present application relates to the field of woodworking machinery, in particular to an edge sealing and gluing device. BACKGROUND

[0002] In the prior art, the edge sealing machine uses a hot melt glue coating device for edge sealing during the edge sealing operation. Since the coating device works in a high-temperature environment for a long time, the glue roller keeps rotating, and the hot melt glue is in a liquid state at high temperature. Therefore, the hot melt glue often flows into the bearing through the gap of the glue roller, and then solidifies in the bearing when it returns to room temperature. Starting again will cause wear to the bearing and transmission shaft, which accounts for more than 70% of the repair problems of the coating device, causing great economic losses. SUMMARY
