    3.How does a carton sealing machine works?

    Working of Carton Sealing Machine

    Working of Carton Sealing Machine

    A carton sealing machine is a device that is used to seal cartons. The machine works by using a hot melt adhesive to seal the edges of the carton. The process is simple and can be completed in a matter of minutes.

    To start, the machine will need to be turned on and the carton will need to be placed onto the platform.

    Once the carton is in place, the operator will need to select the correct settings for the size and type of carton that is sealed.

    After the settings have been chosen, the machine will begin to heat up the adhesive. Once the adhesive has been heated, it will be dispensed onto the edges of the carton. The operator will then need to use a roller to ensure that the adhesive is evenly distributed.

    Once the adhesive has been applied, the operator will need to press down on the lid of the carton in order to seal it shut. The operator may need to apply pressure for several seconds in order for the seal to be secure.

    After a few seconds have passed, the operator can release pressure and remove their hand from the lid.

    The final step is to allow time for the adhesive to cool and set. Depending on how hot the adhesive was when it was applied, this could take anywhere from a few seconds to a few minutes.

    Once cooled, your carton should now be securely sealed!

    4.What are the different kinds of carton sealing machine?

    2 Tape is applied on side instead of center Position of tape drum, compressor rollers and case flaps are unequal Make sure that tape dispenser is in center, parallelize compression rollers and check the case flaps are equal in size
    3 Cutter is not cutting tape The blade is contaminated with adhesive of tap or becomes less sharp due to constant use Clean the blades and remove out glue. Replace cutters if dull
    4 Tape breakage or improper sticking The quality of tape is not good and the adhesive on tape is not sufficient Replace the tape with one having good quality and strong sticking glue
