[0021] It should be noted that the ejector cylinder 2, the door plate 3 and the door opening cylinder 4 are all located above the cigarette missing box detection screening device 18, and the size of the ejecting port is at least 2cm larger than the length, width and height of the cigarette, so as to ensure that the cigarette can effectively pass through the ejecting port when being pushed by the ejector cylinder 2.

[0022] In a specific embodiment, a cylinder bracket 6 is fixed on the outer wall of the cigarette lifting channel 1, the ejector cylinder 2 is fixed on the cylinder bracket 6, a push block 7 is fixed on the telescopic end of the ejector cylinder 2, and a through hole is formed on the side wall of the cigarette lifting channel 1 for avoiding the push block 7.

[0023] In this embodiment, the ejecting cylinder 2 is horizontally arranged, and the push block 7 at the telescopic end of the ejecting cylinder 2 is a rectangular block with a length of 7 cm and a width of 2.5 cm. The size of the through hole in the side wall of the cigarette lifting channel 1 is 1 cm larger than the size of the rectangular block, i.e., the size of the through hole is 8 cm in length and 3.5 cm in width, so as to ensure that the push block 7 can be telescopically operated freely, thereby ensuring that the defective cigarette can be smoothly pushed out of the cigarette lifting channel 1.

[0024] The model of the ejecting cylinder 2 is preferably NT20N-100. In order to ensure that the ejecting cylinder 2 is stably and effectively operated, a position detection magnetic switch 19 can be installed on the ejecting cylinder 2. The position detection magnetic switch 19 is a commercially available component, which can be directly purchased. The installation of the position detection magnetic switch 19 on the ejecting cylinder 2 can play two protection functions. First, when the push block 7 on the ejecting cylinder 2 is not at the original position, the elevator cannot be started, thereby avoiding the collision between the cigarette supporting block in the cigarette lifting channel 1 and the push block 7. Second, when the push block 7 on the ejecting cylinder 2 is not at the original position, the automatic ejecting function cannot be started, thereby preventing the defective cigarette from being damaged and causing mechanical failure.

The model of the door opening cylinder 4 is preferably MA16X50SCA.

[0027] Since the defective cigarette is pushed out of the cigarette lifting channel 1 and is 2.8 meters away from the ground, directly falling to the ground will cause the cigarette sample to be deformed or even damaged, and the cigarette sample will be directly scrapped. Even if the defective cigarette is a finished product, it will also cause the cigarette in the box to be wrinkled and deformed.
