[0002] When cigarette factories produce cigarettes, due to defects in raw materials, failures in cigarette equipment, failures in auxiliary material supply equipment, etc., a certain amount of defective cigarettes with flaws in appearance, insufficient tobacco fullness and tightness, unqualified connection, and inconsistent draw resistance will be produced. In order to improve the utilization rate of raw materials, it is necessary to extract the tobacco from these defective cigarettes without loss and put them into the same level cigarette production line for recycling.

[0003] There are various methods for extracting shredded tobacco on the market, mainly using cutting or beating to break up the cigarettes. The cutting method uses a straight-line cutting method to cut the cigarette paper of the cigarette along its axis. If the cutter cuts the adhesive part of the cigarette, small strips of cigarette paper will be produced, which cannot be removed, and will affect the purity of the shredded tobacco. After the straight-line cutting is completed, the cigarette paper cannot be fully opened due to curling, so the subsequent extraction of the shredded tobacco is difficult and cannot be fully recovered. The beating method separates the shredded tobacco by the collision between the cigarettes, but the shredded tobacco is stretched in the cigarette paper packaging and cannot be completely separated, so both solutions cannot achieve the optimal effect.

The upper surfaces of the cigarette sorting plate 304 and the cigarette conveying plate 307 are sinusoidal wave-shaped and at the same height. The defective cigarettes falling from the defective cigarette outlet 1 onto the cigarette sorting plate 304 are deflected by the cigarette sorting ejector pins 305 on the cigarette sorting plate 304 to form axial cigarettes 306. The axial cigarettes 306 can be conveyed forward by the straight vibrator at the bottom of the valley between the two plates (the cigarette sorting plate 304 and the cigarette conveying plate 307).

[0019] Furthermore, the cigarette sorting plate 304 is provided with a plurality of cigarette sorting ejectors 305.

The cutting feed shaft 409 is located between the cutting shaft 410 and the meshing shaft assembly, and is used to drive the axial cigarette 306 on the self-rotating roller 405 to move toward the cutting shaft 410. The cutting shaft 410 is equipped with a cutting knife 411, and the cigarette paper of the cigarette is cut by the cutting knife 411.

[0027] The cutting feed shaft 409 and the cutting shaft 410 are driven by the cutting power motor 412 to achieve the same direction movement. Furthermore, the two ends of the cutting feed shaft 409 are installed on the cutting fixed seat 408 through bearings, one end extends out and is provided with a first gear; the two ends of the cutting shaft 410 are installed on the cutting fixed seat 408 through bearings, one end extends out and is provided with a second gear, and the other end is driven by the cutting power motor 412, and the first gear and the second gear are connected by a chain. When the cutting power motor 412 drives the cutting shaft 410 to rotate, the cutting shaft 410 drives the first gear to rotate in the same direction through the second gear and the chain, and then drives the cutting feed shaft 409 to rotate in the same direction.

[0028] When in use, the cigarette rotates on the two self-rotating rollers 405 due to friction, and the cigarette on the two self-rotating rollers 405 is pushed to the cutting assembly by the subsequent axial cigarette 306, and the subsequent axial cigarette 306 moves by the meshing movement of the two axes. After the cigarette reaches the cutting feed shaft 409 and the cutting shaft 410, the rotating cigarette is spirally cut by their same-direction movement.

[0029] like Figure 4 As shown, the cigarette paper unfolding module 5 includes an unfolding module placement plate 501, a cut cigarette baffle plate 502, a flexible roller 503 and a cigarette paper unfolding motor 504. The unfolding module placement plate 501 is fixed on the tobacco shred equipment frame 2, the cut cigarette baffle plate 502 is connected to the unfolding module placement plate 501, the cut cigarette baffle plate 502 wraps and fixes the flexible roller 503, and both ends of the flexible roller 503 are installed on the cut cigarette baffle plate 502 through bearings.

[0030] During use, the axial cigarette 306 is spirally cut into cut cigarettes 505 by the cigarette cutting module 4. After cutting, the cut cigarettes 505 fall onto the flexible roller 503. The two pairs of flexible rollers 503 rub the cut cigarettes 505 at differential speeds to separate the tobacco shreds from the cigarette paper waste. The cigarette paper unfolding motor 504 drives the flexible roller 503 to realize its meshing movement.

The tobacco inlet frame baffle 602 wraps the tobacco separation guide tube 601, leaving only an output port directly below, and a tobacco collection material frame 604 is placed directly below the output port for collecting separated tobacco.

[0033] When in use, the cut cigarette 505 basically realizes the state of separation of tobacco and waste after passing through the cigarette paper unfolding module 5, and is transferred into the tobacco separation guide cylinder 601 by the unfolding cigarette slide 608, and the tobacco separation guide cylinder 601 is rotated by the guide cylinder motor 603. The cross section of the tobacco separation guide cylinder 601 is a hexagonal body, and there are a large number of waist-shaped holes on each edge of the hexagonal body. Tobacco can be separated through the waist-shaped holes, and the remaining cigarette paper waste cannot pass through the waist-shaped holes and can only be transferred forward through the guide plate in the tobacco separation guide cylinder 601, and finally transferred out of the tobacco separation guide cylinder 601, and enter the waste paper conveyor belt 606 through the waste paper slide 605, and the waste paper conveyor belt 606 continues to transfer forward, and finally collected in the waste collection barrel 607 for centralized treatment.

[0034] The present invention has the following advantages: a novel spiral cigarette cutting technology is used, and the cutting size of the cutting blade during the cutting process is controllable, so the tobacco is basically not broken, and the tobacco is not contaminated by cigarette waste, so the purity of the tobacco is extremely high; the equipment does not contain wind and thermal equipment during operation, so the moisture content of the recovered tobacco is basically unchanged.
