[0002] The hot air mechanism for packaging bags refers to mechanical equipment used for heating and drying packaging bags. It is mainly composed of a hot air blower, a conveying system and a control system.

[0003] The hot air blower is the core equipment of the hot air mechanism of the packaging bag. It heats the air by burning fuel or electricity to generate high-temperature hot air. The hot air blower usually adopts circulation heating, that is, the heated air is circulated to ensure uniform temperature distribution.

[0004] During the blowing process of the existing hot air blower for packaging bags, the hot air contains impurities such as dust, bacteria, and particulate matter. Therefore, when performing hot air treatment, the hot air needs to be filtered, so a filtering device is needed. The filtering device is usually fixed in the hot air device. Therefore, when the filtering device is blocked, the outer shell needs to be disassembled to clean the filtering device. This method is not only time-consuming and labor-intensive, but also the cleaning efficiency is very slow, which leads to low practicality of the device. To address this problem, we proposed a hot air mechanism for packaging bags. Utility Model Content
