Abstract

The invention discloses a PUR glue dispensing device, wherein the device comprises: a heatable glue barrel, a glue pressing mechanism arranged above the glue barrel, a glue outlet arranged below the glue barrel, and The glue dispensing needle arranged under the glue outlet, wherein the glue pressing mechanism includes a glue pressing body and a glue pressing piston that drives the glue pressing body to move in the glue bucket, and the glue pressing piston and The glue barrel is closed and connected, the glue body and the glue piston are made of silica gel, which solves the problem in the related art that the PUR glue cannot be sealed again after being unpacked and causes waste, and realizes resealing after unsealing , saving costs.

Description

technical field [0001] The invention relates to the field of dispensing equipment, in particular to a PUR glue dispensing device. Background technique [0002] Moisture-curing reactive polyurethane hot melt adhesive (Polyurethane Reactive, PUR for short) works by reacting polyurethane prepolymer with moisture in the air, curing and crosslinking to form a stable chemical structure. Compared with EVA hot-melt adhesive, PUR hot-melt adhesive has a lower melting temperature (110-130°C), has strong adhesion to paper fibers, is resistant to high cold, has good heat resistance, and has a long storage time. And it also has an attractive feature, that is, books bound with PUR glue have good unfolding properties, and have become the new favorite of hot melt adhesives for binding. PUR adhesive is a variety of solid hot melt adhesive, which is the abbreviation of moisture-responsive hot melt adhesive. The difference from traditional hot melt adhesive is that it contains chemical functi...
