technical field

The invention relates to a cigarette receiving channel of a single cigarette detection and removal device of a packaging machine, which is used for receiving and recycling the cigarettes removed from the mold box of a cigarette packaging machine.

technical background

At present, cigarette detection sensors are generally used to inspect the quality of cigarettes in the delivery mold box of the cigarette packaging machine. When it is found that there are empty or missing cigarettes in the mold box, all 20 cigarettes in the mold box will be removed. Sometimes all 20 cigarettes are rejected because of the quality of 1 or 2 cigarettes, and most of them are "good cigarettes". And the rejected cigarettes, no matter they are good or bad, are all treated as inferior cigarettes, causing a large amount of cut tobacco degradation and loss, waste of auxiliary materials (mouth rods, tipping paper, paper coils, glue, etc.). According to the survey, the number of rejected packages per shift of the general cigarette conveying mold box is about 200-300 packs. Some manufacturers are affected by the silk-making process, and even a shift can remove 800-1000 packs. In the long run, it is quite a huge problem. waste.

When the cigarette packaging machine is working, there are several different working states for removing cigarettes: 1. Removing during manual cranking.
