Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a multi-axis stirring hot melt adhesive particle dryer. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Within a certain temperature range, its physical state changes with temperature, while its chemical properties remain unchanged. It is non-toxic and odorless and is an environmentally friendly chemical product. After the hot melt adhesive particles are cut into granules by a granulator, the surface is stained with water stains and needs to be dried in a dryer to facilitate subsequent packaging and transportation. A multi-axis stirring dryer is generally used.

[0003] The multi-axis stirring hot melt adhesive particle dryers currently common on the market are mostly similar in structure. The granular material is poured into the mixing bucket, and the main shaft is driven by a motor to rotate. Two sets of oblique sub-shafts are installed at the bottom of the main shaft. The sub-shafts are spiral stirring shafts, which rotate continuously under the drive of the motor. The two sets of spiral sub-shafts stir the granular material. An electric heating component is generally installed on the inner wall of the mixing bucket to accelerate the drying of the granular material by heating the bucket body. There are some functional deficiencies in actual use and there is room for improvement. For example, most of the multi-axis stirring dryers currently on the market directly heat the mixing bucket and transfer the temperature to the hot melt adhesive particles through the inner wall of the mixing bucket. The heat transfer efficiency is low, and the material in the middle and the granular material at the edge are heated differently. There is still room for improvement in the drying efficiency, and it does not have the function of hot air accelerated drying.
