Description

Technical Field

[0001] The utility model relates to the technical field of wood processing equipment, in particular to a plate edge banding machine. Background Art

[0002] Most of the boards used in the furniture manufacturing industry are compressed boards. In order to achieve exquisite beauty, the compressed boards need to be edge-sealed around the boards after the shape processing is completed to cover the internal structure of the compressed boards, and prevent the wood chips that make up the compressed boards from falling off after a long time of use, thereby extending the service life of the boards. In order to edge-band the boards, edge-banding machines came into being. Edge-banding of boards can not only slow down the release, but also be environmentally friendly, and can also prevent moisture from entering the board substrate to prevent deformation. At present, the board edge-banding machine is mainly composed of a milling device, a pressing device and a polishing device. After the board is milled, the edge banding belt is pressed to the edge of the board through a pressing wheel. The adhesive is rolled. The existing pressing device can only realize the pressing operation of the linear surface of the board. When encountering the edge banding of boards with a certain angle or special-shaped grooves, the rolling coating cannot realize the coating of the curved surface and the special-shaped groove surface. It can only be manually edge-banded by a master with many years of operating experience. The manual use is large, the technical level is high, the processing efficiency is low, the processing cost is high, the dimensional error is large, and the cracking problem is easy to occur, which seriously affects the quality of the edge banding of the board.
