When the flower machine is in use, when the automatic stop device of the flower machine is in use, what is the cause of the failure? As a flower machine manufacturer, let us take you to understand the cause of the failure! 1. The reason for the thick bar not stopping is: 1. The horn head of the flower locomotive is used incorrectly, the diameter is larger than the process requirements, and the control function of the thick bar is lost. 2. The spring sheet of the horn head is too hard, or the distance from the thick bar contact is too large. 3. The thick bar touches the electric contact and loses power. 2. The reason for the thin bar and broken bar not stopping is: 1. The thin bar and the contact of the flower locomotive are installed too low, and the thin bar and the broken bar cannot touch the contact. 2. The thin bar or the broken bar touches the electric contact and loses power. 3. The flower locomotive touches the electric contact for no reason and stops automatically. The reason is: 1. After the insulation wrapping cloth of the conductive copper bar connected to the 6.3 volt control circuit is damaged, it touches the car dealer pole or small blocking plate. 2. The installation distance of the electric contacts of each part is too close, or the screw of the thin strip contact is installed too low, almost touching the lower pressure shaft of the car. It is also possible that the insulator is damaged somewhere, losing the insulation function and causing electric shock. 3. Due to careless cleaning operation, the wire connecting the 6.3 volt control circuit to the copper bar is broken, causing all the process contacts on the car surface to lose power and lose release. 4. In case of unexplained electric shock, it should be linked to the unexplained electric shock cause in the automatic stop device of the small pressure roller of the rear drawing and the unwinding white stop device at the rear of the car, and it cannot be excluded.
