Abstract
An adhesive dispensing device includes a heater unit for melting adhesive material, a receiving space for feeding the heater unit, and a cyclonic separator unit for delivering adhesive pellets to the receiving space. The cyclonic separator unit includes a tangential inlet pipe proximate to a top end of a generally cylindrical pipe, which is connected to the receiving space at an open bottom end. The tangential or spiral flow of air and adhesive pellets generated through the cyclonic separator unit reduces the speed of the air and adhesive pellets to avoid splashing of molten adhesive material while maintaining enough speed to avoid adhesive build up on the generally cylindrical pipe.
