[0004] During the process of realizing the present invention, the inventors discovered that the prior art had the following problems: 1. When adding solid glue into the device for heating, the existing ordinary hot melt adhesive machine generally only relies on the heating wire or heating block outside the device material box for heating, and the heating efficiency is low, which affects the production efficiency; 2. When cleaning the material box inside the device, the existing ordinary hot melt adhesive machine generally requires manual cleaning, which is time-consuming and labor-intensive.
