How to Operate Hot Melt Adhesive? Where To Apply It

Working principle of hot melt glue machine The working principle of hot melt glue machine is to use high temperature to heat solid glue strips or glue particles to a molten state, and squeeze out the molten glue liquid through pressure to achieve the purpose of bonding.

Hot melt glue machine is suitable for PVC packaging industry, woodworking furniture edge banding and lamination, automotive industry interior sealing, headlight manufacturing, windshield assembly, door manufacturing, non-woven industry diapers, adult incontinence products, sanitary napkins and other disposable products, coating and lamination industry (trademark paper, label double-sided tape, medical breathable tape, clothing and clothing lamination), product assembly industry (home appliances, wires and cables).

1. Progressive heating and melting: The heating part is located below the glue. When the melting cylinder is heated, only the bottom layer of glue contacts the heating cylinder, so that it reaches the melting point and melts. The upper part of the glue cylinder is not heated at this time. How much is needed during production, how much is melted, to avoid aging and deterioration of glue due to long-term heating. 2 kg pur-0021 hot melt glue machine (PID)

2. When melting glue, the glue is isolated from the air: there is an O-ring seal between the heating cylinder and the cylinder cover, so that the melted liquid glue will not come into contact with the air, ensuring the use conditions of Pur.

3. Teflon protective layer: the outer surface of the glue cylinder is coated with Teflon coating, and the glue on it is very easy to remove, which can effectively prevent the carbonization of the glue, ensure the best glue, and reduce the blockage of the glue delivery system.

4. Frequency conversion to adjust the glue output: precision gear metering pump, frequency conversion speed regulation and stable motor operation, can accurately control the glue output.

5. Intelligent protection is used for motor operation: the motor is equipped with a forced fan for heat dissipation. When the temperature of the glue cylinder does not reach the set temperature, the motor cannot run, which strengthens the protection of the motor equipment.

6. Monitoring of insufficient glue: an electronic sensor monitors the glue amount in the glue cylinder to prevent alarms due to lack of glue or excessive glue.
