[0029] Working principle: When in use, during the edge cutting process of the carrier tape, the object-carrying groove part of the carrier tape is stuck in the annular groove 901 of the pressing wheel 9 to place the carrier tape on the pressing wheel 9. The pressing wheel 9 and the edge cutting wheel 10 are driven to rotate. By the cooperation of the pressing wheel 9 and the cutting blades 1001 on both sides of the edge cutting wheel 10, the two sides of the carrier tape can be edge-cut. At the same time, when the carrier tape is fed during edge cutting, the subsequent part of the carrier tape passes over the guiding plate 3. By adjusting the position of the limiting plates 4, the two limiting plates 4 can limit the side edges of the carrier tape, and the roller frame 703 is driven to move downward by the electric cylinder 702, so that the pressing roller 11 presses on the edge of the carrier tape, enabling the carrier tape to move stably and linearly during movement, preventing the carrier tape from shifting during the feeding process, and improving the parallelism of the edge cutting of the carrier tape.
