The hot melt glue machine is mainly used for automatic application equipment of hot melt glue spraying, scraping, rolling, coating and injection.

Working principle of hot melt glue machine

The working principle of the hot melt adhesive machine is to heat the heating rod after power on to melt the solid hot melt adhesive in the glue barrel. The melting point of ordinary hot melt adhesive is about 150 degrees to 180 degrees. The heating time depends on the power of the heating rod. After the glue is melted, the electronic control part will display, start the motor, the motor drives the gear pump to apply glue, and put the glue on the product.

Application of hot melt glue machine

Widely used in household products (diapers, sanitary napkins, mousetrap, cockroach house and other disposable products), automotive industry (interior sealing, car lamp manufacturing, windshield assembly, air filter, non-woven composite, shoe industry , printing, electronic product assembly, clothing, self-adhesive stickers, packaging industry (carton packaging, cigarette packaging, Tetra Pak beverage packaging), coating composite industry (trademark paper, label double-sided tape, medical breathable tape), book binding and other industries.

Classification of hot melt machine

Hot melt adhesive machines are divided into dispensing machines, glue spraying machines, glue laminating machines, box sealing machines, etc.

Hot melt machine selection

1. Gluing method

Gluing methods are divided into: manual, foot, semi-automatic, fully automatic;

2. Gluing material and gluing area

The gluing area determines the gluing mode, and according to the size of the gluing area, it is roughly determined whether it is dispensing, spraying or laminating, and then the hot melt adhesive model can be determined.

3. Glue consumption per hour

The amount of glue used per hour is used to judge the capacity of the main machine of the hot melt machine. The host has multiple capacities, or can be customized according to requirements.

4. Dedicated to precision or industry

In recent years, the hot-melt adhesive machine industry has developed a variety of industry-specific adhesive machines, such as PET transparent box sealing machines, carton sealing machines, tire glue spraying machines, small plaster compound machines, etc. Quick selection and matching can be performed by industry distinction.
