AI Technical Summary
Technical Problem
Traditional ovens have limited drying capacity for oil-based adhesive coatings, resulting in incomplete solvent release from the coating and easy formation of bubbles, which affects coating quality and production efficiency.
Method used
Multiple hot rollers are installed between the coating unit and the drying chamber. The substrate is preheated by contacting the hot rollers with the back side of the substrate. The coating is preheated by conducting heat, which avoids surface drying and bubbling, and increases the air velocity and temperature of the drying chamber.
Benefits of technology
It improves drying efficiency, avoids surface drying and bubbling of the coating, and enhances production efficiency and product quality.

Abstract
The utility model discloses an oily glue coating back heat roll preheating coating mechanism, and its base material is exported from base material unwinding mechanism, and is coated in turn through coating mechanism, is dried through drying box, and is collected until finished product winding mechanism, is apart from several hot sticks between coating mechanism and drying box, and the back of base material is preheated and is transported to drying box after being exported from coating mechanism and being arranged around several hot sticks. The utility model discloses the design of multiple hot rolls between coating mechanism and drying box, and the back of coating base material contacts with the surface of hot roll, and the heat conduction is through base material preheating coating, and the coating is preheated from inside to outside, avoids the surface drying and bubble phenomenon of adhesive layer, and is fully preheated before entering drying box, and is dried and solidified again with hot air convection after entering drying box, and the air velocity and temperature of the front drying box can be improved, and the drying efficiency is obviously improved, and the equipment work efficiency is improved, and the product quality is guaranteed.
