[0023] Embodiment. A wrapping machine discharge bag blocking processing device, comprising a code jet, the code jet is connected with the wrapping machine through a conveying belt 1, the conveying belt 1 comprises a transmission shaft, both sides of the transmission shaft are provided with a barrier, the conveying belt 1 is sequentially provided with a workpiece congestion detection device one 2, an intercepting valve 3, a workpiece rejection push plate 4 and a workpiece congestion detection device two 5 from the code jet end to the wrapping machine end;

[0024] The opposite side of the workpiece rejection push plate 4 is provided with a storage platform 6;

[0025] The barrier is provided with a matching notch corresponding to the intercepting valve 3, the workpiece rejection push plate 4 and the storage platform 6;

[0027] The PLC is connected with an alarm. When the conveying belt 1 is congested, the PLC sends a signal to the alarm and starts, timely informing the staff.

[0028] The workpiece congestion detection device one 2 and the workpiece congestion detection device two 5 comprise optical fiber probes 7 and receivers 8 symmetrically arranged on both sides of the conveying belt 1; by symmetrically arranging the optical fiber probes 7 and the receivers 8 on both sides of the conveying belt 1, the optical fiber probes 7 continuously emit light to the receivers 8, when the workpiece is transmitted between the optical fiber probes 7 and the receivers 8, the workpiece blocks the emitted light, sending a signal A to the PLC, when the receivers 8 receive the light of the optical fiber probes 7, it is considered that the production is normally carried out.
