Technical Field

The invention relates to the technical field of edge bonding machines, in particular to a PUR glue pot transfer device for an edge bonding machine.

Background

The glue pot is a glue applying mechanism of a glue applying mechanism for the edge bonding machine, and can be conveniently taken down from the edge bonding machine. The PUR glue pot is a coating mechanism using PUR (Polyurethane Reactive Polyurethane) hot melt adhesive.

The adhesion and toughness of the PUR hot melt adhesive can be adjusted, and the PUR hot melt adhesive has excellent adhesion strength, temperature resistance, chemical corrosion resistance and aging resistance. Most hot melt adhesives on edge bonding machines are heated, and the hot melt adhesives can be heated for use after being bonded and are reversible. The PUR hot melt adhesive is a single-component moisture curing reaction type polyurethane hot melt adhesive, can react with moisture in the air after heating operation and bonding, and is irreversible after reaction (namely, the polyurethane hot melt adhesive cannot be melted after being heated after curing). The PUR hot melt adhesive has excellent performance when used for sealing the edge of the artificial board. But because the edge sealing device can react with moisture in the air, the reaction process is not reversible, and the edge sealing process cannot be interrupted. When the machine needs to be stopped or the PUR hot melt adhesive is not used for a certain period of time, the PUR hot melt adhesive in the adhesive pot can react with water vapor in the air to ensure that the PUR hot melt adhesive cannot be continuously used, so that the waste of the PUR hot melt adhesive is caused, and the adhesive pot is easy to block. When the PUR hot melt adhesive in the glue pot needs to be cleaned, the existing manual glue scraping and cleaning device cannot meet the requirement of large-scale edge sealing production in the market.

Therefore, a PUR glue pot transfer device for an edge bonding machine is needed to solve the technical problems.
