Abstract

The invention relates to an extruder for a hot melt adhesive rod. A spire propel discharging device (6) is arranged under a hopper (4), wherein, a propel screw is drive jointed with an agitating shaft of the hopper (4); a cooling water circular water jacket of a water inlet (1) and a water outlet (5) are arranged around the spire propel discharging device (6); an extruder (10) with a heating unit is connected with lower part of the spire propel discharging device (6), outer end of an extrude screw (9) of the extruder (10) is drivingly connected with a extruded power unit (7); output of the extruder (10) is connected with the extruder head (12) and output of the extruder head (12) is connected with a cooling water groove (13), and a discharge end of the cooling water groove (13) is in serried connected with a first traction roll (14) and a second traction roll (16). The mixed material is enforcedly pushed into the extruder by the spire propel discharging device under momentum function, so quality and productivity of the hot melt adhesive rod are improved.

Description

technical field [0001] The invention relates to a special equipment for manufacturing hot-melt glue sticks, in particular to a hot-melt glue stick extruder. Background technique [0002] Existing hot-melt adhesive stick manufacturing equipment generally adopts reactor mixing and special-purpose extrusion equipment for extrusion. On the one hand, the equipment occupies a large area, the cost is high, and the operation is cumbersome; on the other hand, the semi-finished material mixed in the reactor is easy to change its physical and chemical properties during the turnover process, and the quality of the extruded hot melt glue stick is not satisfactory. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned existing products, and provide a hot-melt glue stick extruder, reduce equipment cost, reduce equipment volume, and improve hot-melt glue stick quality and production efficiency.
