Screw pump-type adhesive feeding device of automatic edge-sealing machine

The utility model discloses a screw pump-type adhesive feeding device of an automatic edge-sealing machine, which comprises a molten adhesive tank, an adhesive storage box, an adhesive feed seat, an adhesive roller and a driving mechanism, wherein the adhesive storage box is communicated with the molten adhesive tank, a adhesive return groove and a adhesive feeding groove are formed on the adhesive feed seat, the adhesive return groove is communicated with the molten adhesive tank, the adhesive feeding groove is communicated with the molten adhesive tank through a screw pump casing, a screw rod is arranged inside the screw pump casing, the screw rod is driven to rotate through a first rotating shaft, the adhesive roller is driven to rotate through a second rotating shaft, and the driving mechanism drives the first rotating shaft and the second rotating shaft to rotate. Accordingly, with the combined action of the screw rod and the screw pump casing, adhesive is fed into the adhesive feeding groove by the rotation of the screw rod; since the screw rod has a good rigidity and a sufficient strength, the adhesive is fed to a high-altitude site; the purpose of feeding the adhesive to the thick wood board is achieved; and the application range is increased. Besides, the screw rod and the adhesive roller are rotated through different rotating shafts, so that the adhesive roller can completely apply the adhesive, which enhances the effect of coating the adhesive on the wood board through the adhesive roller and improves the quality of the edge-sealing operation of the wood board.
