A hot melt glue dispenser device (1) to dispense a continuous or interrupted melt glue wire starting from a solid glue wire (30) that is fed in input to said dispenser device, comprising a melter body (20) comprising an inner passage (21) having an inlet (22) for said solid glue wire (30), and an opposite outlet (23) for said melt glue wire, said melter body (20) having heater members to melt the solid glue wire (30) along the path between said inlet (22) and said outlet (23); a dragging mechanism (40) comprising an inner passage (47, 48) having an inlet (41) and an outlet (42) for said solid glue wire (30), said dragging mechanism being suitable to apply a dragging force to said solid glue wire (30) to transport said solid glue wire (30) from said inlet (41) to said outlet (42) through said inner passage (47,48); a connection structure to which both said melter body (20) and said dragging mechanism (40) are secured, said connection structure being configured to prevent a relative movement between said dragging mechanism (40) and said melter body (20), and vice versa; a spacer member (60) interposed between said melter body (20) and said dragging mechanism (40), defining an inner conduit (66) suitable to make the solid glue wire (30) to pass therein between the outlet (42) of the dragging mechanism and the inlet (22) of the melter body (20), said spacer member (60) having a first end (61) connected to said outlet (42) of the dragging mechanism (40), and a second end (62) connected to said inlet (22) of the melter body (20); said spacer member (60) being made of a thermally insulating material so as to prevent the heat transferring from the melter body (20) to the dragging mechanism (40); a connection structure to which both said melter body (20) and said dragging mechanism (40) are secured, said connection structure being configured to prevent a relative movement between said dragging mechanism (40) and said melter body (20), and vice versa.
