In the utility model, by arranging the hot melt machine body, the melt tank, the motor, the rotating shaft, the support rod, the stirring rod, the heat conducting plate and the heating tube structure, the heat conducting plate and the heating tube are more closely fitted to the rubber block inside the melt tank, when the motor output power drives the rotating shaft to rotate, the rotating shaft drives the support rod and the stirring rod to rotate, and the four groups of stirring rods can effectively improve the stirring efficiency, fully stir the unmelted rubber block, so that the rubber block is heated evenly, and the melting is accelerated, and the occurrence of slag is also avoided. By arranging the thermal insulation layer and the universal wheel structure, the thermal insulation layer uses the thermal insulation material prepared by polyurethane, which has excellent water resistance, mechanical strength and heat resistance, so that the glue after the rubber block is melted can maintain the appropriate temperature for a long time, thereby improving the working efficiency of the hot melt adhesive machine. The hot melt adhesive machine needs to be frequently moved to the working position during the use of the project, and the universal wheel is installed at the bottom, which can be convenient for moving the hot melt adhesive machine, thereby improving the flexibility of the hot melt adhesive machine.

[0013] 2. In the utility model, by providing a cover plate, a sealing gasket, a groove, an extension strip, and a handle structure, the hot melt glue machine needs to close the cover plate when melting the glue block. The sealing gasket is fixed on the surface of the cover plate, which can improve the sealing of the glue melting tank and effectively avoid the heat dissipation inside the glue melting tank, which causes the glue temperature to drop and the glue cannot be discharged normally. The handle installed on the surface of the cover plate can facilitate personnel to open the cover plate and place the glue block, thereby improving the working efficiency of the glue melting tank. When the cover plate is closed with the glue melting tank, the groove fits with the extension strip, which further improves the sealing of the glue melting tank during operation and makes the thermal insulation effect of the glue melting tank better. At the same time, the groove and the extension strip provide a reference standard for closing the cover plate, so that the cover plate can be closed more accurately.
