The waste discharge baffle 545 is fixedly arranged on the waste discharge rotating rod 544. In use, if the card is qualified, the waste discharge motor is not worked, and the card is conveyed from the front conveying belt structure to the rear conveying belt structure. If the card is unqualified, the waste discharge motor is worked to drive the waste discharge connecting rod to rotate, thereby driving the waste discharge rotating rod to rotate, and further driving the waste discharge baffle to rotate downward, so that the waste discharge baffle blocks the forward movement of the card, and the card falls into the waste discharge gap.

[0047] The detection mechanism 4 is used for detecting the card of the conveying mechanism 5.

The detection slide rail 41 is rotatably arranged on the detection slide rail 41. The detection camera 43 is arranged on the inner top surface of the detection bin 42. The detection camera is used for checking whether the card is qualified.

[0048] In use, the feeding mechanism conveys the card to the front end of the conveying guide-in structure. The conveying guide-in structure guides the card into the front conveying belt structure. The card is conveyed to the detection mechanism. The detection mechanism detects the card. The card is continuously conveyed to the pressing assembly. The pressing assembly flattens the card. When passing through the waste discharge structure, if the card is unqualified, the waste discharge structure works to make the card fall into the waste discharge gap. If the card is qualified, the card enters the rear conveying belt structure and finally falls into the material collecting hopper.

[0049] The material bin mechanism, the feeding mechanism, the detection mechanism and the conveying mechanism are arranged, so that the card can be automatically fed, detected and discharged. The degree of automation is high. The working efficiency is greatly improved, and the production cost is reduced.
