Abstract
A paper tube making apparatus includes a fixed rod, a paper tape winding mechanism, a glue applying device, a length measurement unit, and a hot airflow generation unit. The length measurement unit measures a conveying speed of a paper tape, and the glue applying device is operable to coat glue on the paper tape. The hot airflow generation unit is located downstream of the length measurement unit and the glue applying device and is operable to adjust the flow rate and temperature of a hot airflow according to the conveying speed of the paper tape. The hot airflow generation unit blows the hot airflow generated thereby toward the paper tape to control the extent of drying of the glue, so that the extent of drying of glue coated on the paper tape is not affected by the environment temperature and humidity and the quality of the paper tube so fabricated is enhanced.
