At the same time, the tape pressing cylinder 309 extends, so that the tape pressing block 310 descends, and the tape 111 is pressed again. The upper cutting cylinder 302 retracts, driving the upper blade 305 to rise, and the lower cutting cylinder 306 retracts, driving the lower blade 308 to descend; at this time, the two buffer cylinders 105 arranged in parallel reciprocate once, buffering the tape 111 by 60mm, and preparing for the next round of work; at the same time, the transmission line mechanism 5 moves, and the heparin tube 504 with tape tied is transferred to the next station, and the heparin tube 504 without tape tied is transferred to this station, waiting for bandaging. The cycle is repeated until the sensor 112 detects that there is no tape, and the set alarm can light up to remind the operator to change the material.
