Hot melting device for hot-melt pressure-sensitive adhesive

Abstract

The utility model relates to the technical field of hot-melt pressure-sensitive adhesive production, in particular to a hot-melt pressure-sensitive adhesive hot melting device. Comprising a heating cylinder, a stirring piece and a scraping ring, an opening is formed in the upper end of the heating cylinder, a cover plate is buckled to the opening, the stirring piece comprises a hollow rotating shaft and a hollow stirring shaft, the hollow rotating shaft is rotationally installed on the cover plate, a power assembly A used for driving the hollow rotating shaft to rotate is installed on the cover plate, and the hollow stirring shaft is rotationally installed at the bottom end of the hollow rotating shaft; a power assembly B used for driving the hollow stirring shaft to rotate is installed at the upper end of the hollow rotating shaft, the outer wall of the hollow rotating shaft is sleeved with the material scraping ring, and a movable rod movably penetrating through the cover plate is vertically connected to the material scraping ring. By arranging the rotatable hollow stirring shaft, the stirring effect of the device is improved, and when the hollow stirring shaft rotates to be vertically downward, excess materials on the surface of the hollow stirring shaft can be conveniently cleaned, so that the operation is relatively convenient.
