Problems solved by technology

[0003] After the hot melt adhesive is packaged and discharged, it needs to be cooled through the cooling line. The hot melt adhesive package floats on the water in the water channel of the cooling line. Driven by the water flow, the water flow is not as easy to control as the conveyor belt. The hot melt adhesive package may gather together during the conveying process, making it difficult to dissipate heat, and the cooling effect is poor. Not completely cooled, so the hot melt adhesive package entering the cooling line at the same time should not be too much
In addition, if the hot melt adhesive package is conveyed quickly in the assembly line, it will accumulate at the discharge port and affect the discharge
[0004] After the hot-melt adhesive bag is cooled and discharged from the cooling line, there are many cooling water droplets on the surface of the hot-melt adhesive bag, which cannot be packed into the carton. The hot-melt adhesive bag is dried, but the hot-melt adhesive bag cannot be heated and dried, which will cause the hot-melt adhesive bag to heat up again. If a general electric fan is used to blow the hot-melt adhesive bag, the drying efficiency is low and the drying effect is poor. , prone to residual water droplets

Abstract

The invention relates to the field of liquid packaging machines, in particular to a hot melt adhesive cooling and drying method and a hot melt adhesive cooling and packaging assembly line. The method comprises the following steps that S1, hot melt adhesive bags packaged with plastic films are treated through a shear type hot melt adhesive packaging machine; S2, hot melt adhesive is cooled, specifically, the packaging bags containing the hot melt adhesive fall into a cooling assembly line arranged below to be cooled; and S3, the hot melt adhesive packaging bags are dried, specifically, the cooled hot melt adhesive packaging bags are conveyed to an air-blowing drying mechanism through a conveying belt to be dried. The hot melt adhesive cooling and drying method and the hot melt adhesive cooling and packaging assembly line have the characteristics of being reasonable in structure and integrating hot melt adhesive packaging, cooling and air-drying.

Description

technical field [0001] The invention relates to the field of hot-melt adhesive packaging, and relates to a hot-melt adhesive cooling and drying method and a hot-melt adhesive cooling and packaging assembly line. Background technique [0002] In the production process of hot melt adhesive, firstly, the prepared hot melt adhesive raw material is added to the reaction kettle, heated up in the reaction kettle to make it melt, and stirred evenly, then the melted glue in the reaction kettle is cooled to a certain temperature and flowed into the packaging machine , and then put the hot melt adhesive into the packaging film through the packaging machine, and then heat seal and cut the packaging film and then pack it into bags. The itinerary takes up a lot of space. [0003] After the hot melt adhesive is packaged and discharged, it needs to be cooled by the cooling line. The hot melt adhesive package floats on the water in the water channel of the cooling line and is transported fo...
