[0048] Working principle: When the hose reaches the lower end of the internal heating component 1 along with the cup holder, the cup holder is pushed into the internal heating port. At this time, the internal heating port begins to heat up and soften the hose tail. After softening, it reaches the tail clamping component 2. After entering the tail clamping component 2, it performs a tail clamping action to clamp the hose tail. Then it enters the cooling component 3, which cools the clamped tail until it hardens. Then it enters the tail shearing component 4, where a cutter cuts off the excess part generated during hot air and tail clamping, ensuring the straightness of the tail. The cut waste is recycled through the tail shearing waste collection pipe of the tail shearing component 4. Finally, it enters the laser marking adjustment component 5, where laser marking is performed at the corresponding position on the hose. The height is adjusted according to the length of the hose body. The output dovetail component descends to the hose tail to provide support.
