[0038] Working principle:

[0039] Step 1: When the cigarette strips on the front production line are transported over, they will be sent to the conveyor belt 11, and the conveyor belt 11 will drive the cigarette strips forward. When the cigarette strips arrive at the adjusting mechanism 20, if the cigarette strips are in a lying state, they will pass under the roller 1 25, and then be intercepted by the diverter plate 3 34 and change from a horizontal posture to a vertical posture, and then driven by the conveyor belt 11 to the roller 2 40. The roller 2 40 drives the cigarette strips forward and transports them toward the limit plate 4 41. After the cigarette strips come into contact with the limit plate 41, since the cigarette strips are in a vertical state, they will gradually become vertical under the guidance of the limit plate 41.

[0040] Step 2: If the cigarette cartons are in a stacked state, the diverter plate 24 will intercept the cigarette cartons stacked high. After the cigarette cartons below pass through, the cigarette cartons above will naturally fall on the conveyor belt 11 and repeat the operation of step 2. If the cigarette cartons are in a standing state, they will be intercepted by the diverter plate 24 and guided to between the two diverter plates 24 by the inclined surface at the rear end of the diverter plate 24. When the cigarette cartons pass through here, their tops will abut against the guide plates 51. The raised rear end of the guide plates 51 prevents scratches or squeezing of the cigarette cartons. The curved surface at the bottom of the guide plates 51 will guide the cigarette cartons to gradually rotate during the forward movement. When the tail end of the cigarette cart leaves the passage between the two diverter plates 24, the cigarette cart will fall down and become flat, and then repeat the operation of step 2.

[0041] Step three: The cigarette strips pass through the regulating mechanism 20 and arrive at the drum 2 40, and become a flat vertical state under the guidance of the limit plate 4 41. Then, the motor inside the fixed plate 32 drives the diverter plate 2 31 to rotate to guide the cigarette strips. The diverter plate 3 34 further guides the loosened cigarette strips and sends them to different next working platforms.
