[0002] In industries such as chemical engineering, plastics, and rubber, stirring equipment is an indispensable process equipment. Due to its unique adhesive properties and environmental friendliness, hot melt adhesive is widely used in various packaging, bonding, and coating processes.

[0003] Hot melt adhesive has high viscosity and fluidity at high temperatures, which requires the stirring equipment not only to be able to stir the hot melt adhesive evenly but also to ensure that excessive heat accumulation does not occur during the stirring process to avoid degradation and burning of the hot melt adhesive. Most of the hot melt adhesive mixers on the market currently have problems such as uneven stirring and low stirring efficiency. Moreover, due to the high viscosity of the hot melt adhesive, when stirring, the bottom material is easily lifted upward under the action of the stirring blades of the stirring paddle, resulting in voids in the bottom hot melt adhesive and poor stirring effect.
