Referring to fig. 7, the material abnormality processing mechanism includes a laser intermittent blocking sheet 55, a linkage shaft 54, a laser transmitter 57, a laser receiver 56, a main control chip 59 and an alarm 61. One end of the linkage shaft 54 is fixedly connected with the center of the laser intermittent blocking sheet 55, a rotating bearing 51 is respectively arranged at the other end of the linkage shaft 54 and the position close to the laser intermittent blocking sheet 55, and a bearing fixing sleeve 50 is arranged on the rotating bearing 51. Teeth 53 are arranged on a linkage shaft 54 between the two rotary bearings 51, the material wire 52 output between the output shaft of the feeding driven gear 3 and the material pressing device 44 passes through the teeth 53 on the linkage shaft 54 and then is output to the printing head, and along with the normal output of the material wire 52, the material wire 52 can drive the linkage shaft 54 to rotate at a constant speed. Once the output of the wire 52 is abnormal (thickened, thinned, without material or blocked, etc.), the linkage shaft 54 cannot rotate at a constant speed. The laser intermittent barrier 55 is driven by the uniform or non-uniform rotation of the linkage shaft 54 to perform corresponding uniform or non-uniform rotation.

As the laser intermittent blocking piece 55 rotates, the laser receiver 56 may intermittently receive the laser signal emitted from the laser emitter 57 through the through hole. When the laser intermittent barrier 55 rotates uniformly, the time for the laser receiver 56 to receive the laser signal through the through hole (i.e., the time for the laser receiver 56 to pass through each through hole) is fixed, and the time for the laser receiver 56 to receive no laser signal (i.e., the time for the laser receiver 56 to pass through between two adjacent through holes) is also fixed. The laser receiver 56 transmits the condition of the received laser signal to the main control chip 59 in real time through the signal transmission line 58, the main control chip 59 processes the signal sent by the laser receiver 56, once the time length that the laser receiver 56 receives or cannot receive the laser signal exceeds the preset time length range is found, the main control chip 59 sends a material abnormal signal to the alarm 61 through the signal transmission antenna 60, the alarm 61 sends an alarm signal after receiving the material abnormal signal, the alarm filament 52 outputs the abnormal signal, and the chip main control board 37 in the control mechanism 1 controls the stop of the printing work. Because each feeding main body corresponds to a material exception handling mechanism, the alarm 61 can quickly find out which station has an exception condition after sending an alarm signal, so that the inspection and the handling are convenient.
