Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive production, in particular to a flat cooling mechanism for aging-resistant hot melt adhesive. Background Technique

[0002] Hot melt adhesive is a plastic adhesive. Within a certain temperature range, its physical state changes with the change of temperature, while its chemical properties remain unchanged. It is non-toxic and odorless, belonging to an environment-friendly chemical product. Since the product itself is solid, it is convenient for packaging, transportation and storage.

[0003] The production process of hot melt adhesive includes mixing, melting, filtering, coating, etc. The melted and filtered hot melt adhesive is extruded from the discharge head to form a long strip, and it needs to be cooled to harden and form. Most of the existing cooling mechanisms for aging-resistant hot melt adhesive use clear water to cool the extruded long strip of hot melt adhesive. However, when the hot melt adhesive in the molten state immediately contacts the clear water, cracks, bubbles, etc. will be generated inside due to the large temperature difference. For this reason, we propose a flat cooling mechanism for aging-resistant hot melt adhesive. Content of the Utility Model
