The working principle of the hot melt glue machine mainly includes the following steps:
1. Heating: Through electric heating or other heating methods, the hot melt glue in the rubber bucket is heated to the melting state.
2. Conveying: The melted hot melt glue is transported to the glue gun or hose under pressure.
3. Extrusion: Hot melt glue is extruded from the outlet of the glue gun or hose, and is contacted and bonded with the bonded object under the action of pressure and temperature.
4. Cooling and curing: Hot melt adhesive is gradually cooled and cured after contact with the bonded object, so as to achieve bonding.
Medical hot melt adhesive machine is mainly used in the medical field, such as surgical clothes, medical dressings, etc.
It usually has precise temperature control and stable gluing performance to ensure the quality and safety of bonding. In use, it is necessary to adjust and operate according to the specific material and process requirements.
The glue speed setting of the medical hot melt glue machine needs to be determined according to the specific situation, in general, the common glue speed is about 10~30 cm/minute is more appropriate.
However, the actual gluing speed will also be affected by many factors such as the characteristics of the hot melt adhesive, the nature of the bonded material, and the process requirements, which need to be tested and adjusted in practical applications to achieve the best bonding effect.
The main uses of hot melt adhesives include:
1. Packaging industry. Used for making cartons, sealing tapes, etc., to ensure the safety and sealing of packaging.
2. Home improvement. In furniture, flooring, wallpaper and other decoration used for bonding, reinforcement, so that decorative items more firm, more beautiful.
3. Automobile manufacturing. Used to reinforce and glue auto parts, such as body, doors, seats, etc.
4. Textile industry. Used for bonding various fabrics, yarns, fabrics, or for textile repair and maintenance.
5. Electronic products. It can be used to seal electronic, mechanical equipment and electrical instruments to prevent water, dust, dust and other media from entering.
Hot melt adhesives come in various forms, including hot melt strips, hot melt pellets, hot melt powder, hot melt film and hot melt adhesive blocks, etc., suitable for different bonding needs.
