Description

Edge sealing mechanism of rotary multi-glue pot, edge sealing machine and glue exchanging method Technical Field The invention relates to the technical field of plate processing equipment, in particular to a rotary multi-glue pan edge sealing mechanism, an edge sealing machine and a glue changing method. Background The plate edge bonding machine is one of the processing equipment commonly used in the plate furniture industry and has the function of bonding the adhesive tape on the cut surface of the plate. The cut surface of the plate can be coated after edge sealing treatment. After the edge of the plate is sealed, the plate is more attractive and has a decorative effect, and on the other hand, the invasion of external moisture can be avoided, and the service life of the plate is prolonged. The invention relates to a multi-glue pot edge banding machine, in particular to a multi-glue pot edge banding machine which is characterized in that a plurality of glue boxes are arranged on a rotary table at intervals, different types of hot melt adhesives are correspondingly contained in the glue boxes, when the multi-glue pot edge banding machine is used, the rotary table is driven by a driving device to drive the glue boxes needing to use the hot melt adhesives to rotate to a heating system, the heating system heats the glue boxes matched with the glue boxes, the heated hot melt adhesives flow to the side edges of a plate to realize the gluing treatment of the plate, and the rotary conversion of the glue boxes is adopted to realize the edge banding requirement of different types of hot melt adhesive gluing switching on a single edge banding machine. Although the multi-glue pot edge bonding machine is provided with a plurality of glue boxes filled with different types of hot melt adhesives, the rotary table is utilized to rotate so as to realize the conversion of the glue boxes of the different types of hot melt adhesives, and further, the requirements of different glue coating are met.
