Then, the servo motor 132 of the pitch-varying driving mechanism 13 in the cutting pitch-varying mechanism 1 starts to rotate, the servo motor 132 drives the second gear 131 to rotate, and the second gear 131 and the first gear 151 are gear pairs and are in meshing transmission; at this time, the first gear 151 rotates, and the cam follower 123 in each traverse assembly 12 receives a circular arc force inside the mounting groove 1512 of the first gear 151 and moves inward in the gear diameter direction; the cam follower 123 drives the sliding rail connecting block 122 to move, and the sliding rail connecting block 122 drives the corresponding cutting assemblies 13 to move inwards, that is, the three groups of cutting assemblies 13 move gradually towards the center of the bottle cap.

At the same time, the rotating motor 331 in the cutting power mechanism 3 starts to rotate, the connecting belt 342 of the connecting assembly 34 transmits power to the belt wheel 113 of the cutting pitch-changing mechanism 1, at this time, the belt wheel 113 rotates, and the blade 111 rotates; meanwhile, the cutting assembly 11 in the cutting pitch-changing mechanism 1 moves inwards, the tension applied to the connecting belt 342 is gradually reduced, the pressure of the connecting belt 342 on the tension wheel 343 is reduced, at the moment, the tension sensor 345 sends the change value to a control system (not shown, such as a PLC system) of the full-automatic cutting and bottle opening device, the control system timely sends an instruction to control the electric proportional valve, so that the linear sliding assembly 32 is controlled to do the return movement, the driving mechanism 321 pulls the rotating assembly 33 backwards, at the moment, the connecting belt 342 is tensioned again, the power of the rotating motor 331 of the rotating assembly 33 is continuously transmitted to the cutting assembly 11 through the connecting belt 342, and the blade 111 continuously does the rotating movement.

Meanwhile, the rotary cylinder 221 in the bottle body rotating mechanism 2 drives the workpiece a to rotate.

Meanwhile, when the cutting pitch-changing mechanism 1 performs a cutting feeding action and the rotating motor 331 in the cutting power mechanism 3 provides rotating power for the blade, the driving mechanism 321 also adjusts the position of the rotating motor 331 in real time to tension the connecting belt 342 in real time, so as to keep the tension of the connecting belt 342 constant, and further ensure that the blade 111 can perform a rotating motion and cut a medicine bottle until the bottle cap is cut off from the medicine bottle smoothly during the feeding.

When the cap is cut off from the vial smoothly, the rotary motor 331 of the cutting power mechanism 3 is stopped, the cutting distance varying mechanism 1 keeps the cutting position unchanged, and then the flexible pecking jaw 52 is operated to clamp the cut cap.

Thereafter, each mechanism returns to the origin position: the lifting motor 43 of the lifting mechanism 4 rotates reversely to drive the cutting assembly 11 to move upwards and reach the original position, the servo motor 132 of the cutting pitch-changing mechanism 1 rotates reversely, the cutting assembly 11 returns to the original position, and meanwhile, the translation motor 231 in the bottle body rotating mechanism 2 rotates reversely and drives the medicine bottle with the cut bottle cap to return to the original position.

Finally, the flexible pecking jaw 52 is released and the cap falls into the receiving chute at the bottom of the machine while the mechanisms have been returned to the home position. The actions are repeated in sequence to finish the automatic cutting of the batch medicine bottles.
