Hot melt glue carton sealing machine is an automatic or semi-automatic packaging equipment that is upgraded and transformed on the basis of packaging machine. It can automatically complete glue spraying, ear folding, sealing, etc.

The hot melt glue box sealing machine uses an automatic glueing method to glue the folded sides of the carton. It is suitable for gluing a variety of carton sizes. It has a simple appearance, reduces power consumption, conforms to the concept of environmental protection and energy saving, and has low investment costs. The carton sealing machine is highly efficient, with a production capacity of 30-50 boxes/minute. The efficiency is 2-3 times that of manual carton sealing. It has a wide range of applications and can be adjusted according to the size of the carton anytime and anywhere.

Possible problems with hot melt glue carton sealing machine

1. Insufficient and uneven gluing:

The hot-melt glue machine has blocked glue during the pre-melting process or at the glue outlet, which may lead to uneven glue application. This is because the operating load capacity of the machine is insufficient to completely melt the adhesive, or the temperature setting of the hot melt glue machine is too low.

2. Excessive smoke or smell:

Similar problems can occur due to reasons such as the set temperature is too high, the mechanical current device is incorrect, the thermostat of the hot melt adhesive machine is faulty, the heater is faulty, the hot melt adhesive tank is not clean and other impurities or dust are mixed in, etc.

3. "Glue thread" is produced when applying glue:

The heating temperature set by the hot melt glue machine is low, the glue application procedures and methods are inappropriate (the amount of glue applied is too large), the temperature difference between the outdoor and indoor areas (the construction site is large, and the convection of the air can easily cause the ambient temperature to change (especially in winter)). Stringing phenomenon.

4. There is dirt or excessive adhesive on the edge of the box sealing machine.

Excessive glue application, mechanical failure during the trimming process, improper glue application position, and excessively high temperature of the hot melter may cause glue accumulation, thereby affecting the glue application effect.

5. Release after bonding:

The cause is that the hot melt glue carton sealing machine is cold (suddenly cooled) during the bonding process. Stable bonding conditions should be maintained (including temperature, pressure, and working speed, etc.), otherwise the bonding effect will be affected. In addition, incorrect selection of glue will also cause the carton bonding effect to be insignificant.
