The invention discloses a device for supplying unmelted
hot melt adhesive pieces. The structure of the device comprises a
power cord, a control panel, a feedwell, a preheating
thermal insulation device, an air vent, a steel backing plate, a
handle, an opening and closing door, a plug pin, and a feeding funnel, wherein the feeding funnel is embedded in the left end of the upper surface of the preheating
thermal insulation device, the steel backing plate is welded with the lower end of the preheating
thermal insulation device, the air vent is embedded in the upper end of the front side of the preheating thermal insulation device, the plug pin is welded with the left end of the opening and closing door, and the opening and closing door is hinged to the left end of the front side of the preheating thermal insulation device by the plug pin. The device for supplying unmelted
hot melt adhesive pieces heats the
hot melt adhesive pieces firstly through the preheating thermal insulation device when supplying the
hot melt adhesive pieces to make the temperature of the
hot melt adhesive pieces between the
freezing point and the
melting point, so that the
hot melt adhesive pieces can quickly reach the
melting point temperature when entering a melting box of a hot melt adhesive
machine, thereby shortening the melting time of the hot melt adhesive pieces, improving the hot melt efficiency, ensuring the adhesive supply speed, and avoiding feeding interruption of the hot melt adhesive
machine during the adhesive application.
