[0048] Working principle: When the hose reaches the working position at the lower end of the internal heat component 1 along with the cup holder, the cup holder is pushed into the internal heat port. At this time, the internal heat port starts to heat up and soften the tail of the tube. After softening, it reaches the tail-clamping component 2. After entering the tail-clamping component 2, a tail-clamping action is performed to clamp and seal the tail of the hose. Then it enters the cooling component 3, and the clamped tail is cooled to harden through the cooling component 3. Then it reaches the tail-cutting component 4, and the excess parts generated during hot air and tail-clamping are cut by a cutting knife, and the straightness of the tail is ensured. The cut waste is recycled through the tail-cutting waste collection pipeline of the tail-cutting component 4. Finally, it enters the laser coding adjustment component 5, and laser coding is performed at the corresponding position of the hose. The height is adjusted according to the length of the tube body, and the output dovetail component descends to the tail of the tube to play a supporting role.
