[0040] Specifically, as shown in Figure 7As shown, the first fixed plate 612 and the second fixed plate 613 abut on the outer side of the two side partitions 31 at the inlet of the cutting device 3, so that the whole fixing frame 61 is fixed on the inlet of the cutting device 3.

[0041] In an optional implementation of the embodiment, the deviation rectifying sensor 62 comprises a sensor fixing shaft 621, a sensor fixing block 622, a sensing signal transmitter 623 and a sensing signal receiver 624, one end of the sensor fixing shaft 621 is connected to the sensor fixing block 622, and the sensing signal transmitter 623 and the sensing signal receiver 624 are arranged at the upper end and the lower end of the sensor fixing block 622 respectively.

At this time, the deviation rectifying driving motor 4 drives the placing frame 22 to move leftward on the deviation rectifying guide rail 5 until the area of the sensing light signal received on the sensing signal receiver 624 is equal to the standard value, and the deviation rectifying operation is completed.
