The invention discloses a panel furniture sealing edge cleaning method. The furniture sealing edge cleaning method disclosed by the invention comprises the steps of spray coating of separating agents,pre-milling, application of adhesive, conveying of a pressing belt, flush trimming and cleaning of a cloth wheel. According to the method disclosed by the invention, the separating agents are coatedon a processing panel through spraying firstly, so that hot melt adhesive is easy to remove, and the whole process is finished by a machine; the injury to human bodies due to direct contact with chemicals, such as the separating agents and the hot melt adhesive, is avoided; the separating agents are coated with a separating agent coating machine directly, and the utilization rate of the separatingagents can be improved greatly; the shortcomings of material waste and out-of-control amount of the materials due to manual operation are overcome; the problems of removing adhesive residues and excessive adhesive from the processing panel in the sealing edge procedure can be solved properly; the production efficiency can be improved, and the labor cost is saved.
