[0002] An extruder is an extrusion device specially used for producing plastic products. It can produce plastic products of various shapes. As a plastic adhesive, hot melt adhesive can also be extruded by an extruder. The production process is as follows: the extruder squeezes the hot melt adhesive sent from the hopper forward, and then squeezes the hot melt adhesive into strips through the die head. The die head is equipped with a cutting device, which can cut the extruded strip hot melt adhesive into granular hot melt adhesive, and finally cool the hot melt adhesive.

[0003] In the prior art, the cut hot melt adhesive is usually cooled naturally or air-dried. These cooling methods take a long time and are not conducive to the rapid molding of the hot melt adhesive. It is also difficult to keep the hot melt adhesive strip stable when the hot melt tube adhesive strip is transported and cut, resulting in uneven cutting of the hot melt adhesive strip, thereby reducing the cutting efficiency.
