[0001] The utility model relates to the technical field of packaging, in particular to a carton sealing and tape pulling auxiliary device. Background Art

[0002] In the packaging industry, standard cartons are sealed with automatic carton sealers to save labor and improve efficiency. The upper and lower tapes are automatically pulled during the sealing process. Due to the working principle of the carton sealer, the lower tape must be upright and tangent to the rear tape roller before it is applied. This allows it to stick to the side of the tape properly and to stick to the bottom of the box as the box passes through the carton sealer, thus achieving the automatic tape pulling process.

[0003] However, each time the carton sealing process is completed, the tape will fold downward when the spring is retracted due to factors such as vibration, tape viscosity, and gravity, causing the tape to curl up or stick to the sealing machine head.
