[0067] The first aspect of this application provides a waste cigarette recycling device, including a vibrating trough 6, a waste removal unit, a waste temporary storage unit, a waste storage container, and a waste detection system.

[0068] The vibrating trough 6 is used to separate waste cigarettes and waste dust. The impurity removal unit is used to remove metallic impurities from the waste cigarettes. The waste storage unit is used to temporarily store waste dust. The waste storage container is used to collect clean cigarettes and waste dust. The waste detection system controls the working status of the waste storage unit by detecting the position of the waste storage container and the state of the waste therein.

[0069] The vibrating groove 6 is inclined downward at 15° relative to the horizontal plane. The bottom front end of the vibrating groove 6 has a circular sieve hole with a diameter of 3mm. The lower part of the vibrating groove 6 is connected to a vibrating support that can vibrate.

[0070] The impurity removal unit is located at the end of the vibrating groove 6 and consists of a cuboid magnet with the same width as the vibrating groove 6.

[0071] The waste storage unit is a V-shaped hopper 13. One side wall of the V-shaped hopper 13 is a movable wall, which is connected to a drive mechanism 8. The drive mechanism 8 controls the opening and closing of the V-shaped hopper 13.

[0072] Preferably, the drive mechanism 8 is a cylinder.

[0075] The second guide plate 11 is disposed below the open side to guide impurities in the V-shaped hopper 13 to move along the second guide plate 11 to the bottom direction of the V-shaped hopper 13;

[0076] The upstream end of the first guide plate 9 is connected to the second guide plate 11, and the downstream section of the first guide plate 9 is connected to the drive mechanism 8;

[0077] The first guide plate 9 is configured to move between a first state and a second state under the drive of the drive mechanism 8:

[0078] When the first guide plate 9 is in the first state, the first guide plate 9 and the second guide plate 11 do not close the bottom of the V-shaped hopper 13, and can guide impurities from the bottom of the V-shaped hopper 13 to the waste collector 3;

[0079] When the first guide plate 9 is in the second state, the first guide plate 9 and the second guide plate 11 can close the bottom of the V-shaped hopper 13 to temporarily store powdery impurities.

[0080] The first guide plate 9 and the second guide plate 11 form the movable wall of the V-shaped hopper 13.

[0081] The waste storage unit is located below the circular screen hole at the front end of the vibrating trough 6.

[0082] The waste storage container consists of two rectangular metal bins with casters at the bottom, used to collect waste dust and waste cigarettes, respectively.

[0083] Preferably, the waste storage device includes: a waste collector 3 and a clean cigarette collector 4.

[0084] The waste detection system includes two sets of level detectors and two sets of position detectors. The level detectors detect the level status of waste materials in the waste storage container, and the position detectors detect the position status of the waste storage container.

[0085] Preferably, the two sets of material level detection are photoelectric detectors, located above the two waste storage containers respectively. The material level in the waste storage containers controls the switching state of the waste temporary storage unit and the vibration state of the vibrating trough 6. The two sets of position detectors are located on the outer wall of the inner side of the two waste storage containers respectively. The position of the waste storage containers controls the switching state of the waste temporary storage unit and the vibration state of the vibrating trough 6 respectively.

[0086] One embodiment of this application is as follows: Figure 1-4 As shown, the waste cigarette recycling device of this application filters non-recyclable tobacco dust, filter rod cellulose acetate dust, and paper dust from waste cigarettes through a vibrating trough 6 screen and compressed air. Then, it removes metallic foreign objects from the waste cigarettes by magnetic separation and filtration to obtain pure cigarettes, which are then sorted and processed by a pure cigarette collector and a waste collector.

[0087] The waste cigarette recycling device includes: a cover door 1, a cabinet 2, a waste collector 3, a clean cigarette collector 4, casters 5, and a vibration recycling unit.

[0088] The vibration recovery unit includes: a vibration groove 6, a pneumatic vibrator 7, a drive mechanism 8, a smoke dust guide plate 9, a damping spring vibration isolator 10, a smoke dust guide plate 11, and a magnet 12.

[0089] The vibration groove 6 has an angle of 15° with the horizontal position, the magnet 12 has the same width as the vibration groove 6, and the magnet 12 has a length of 10 cm.

[0090] The waste cigarette recycling device also includes: a first level detector, a first arrival detector, a second level detector, a second arrival detector, and an alarm.

[0091] The working principle of the waste cigarette recycling device is as follows:

[0092] When the cigarette making machine is running, the waste cigarette purification and recycling device starts working. Waste cigarettes fall into the vibrating trough 6. As the waste cigarettes move forward with the vibrating trough 6, they pass through a screen to remove powdery impurities. The powdery impurities fall into the waste collector 3 through the first guide plate 9 and the second guide plate 11. As the waste cigarettes continue to move forward with the vibration of the vibrating trough 6, when they pass through the magnet 12, the metal waste in them is attracted by the magnet 12, and finally, the purified cigarettes fall into the purified cigarette collector 4 for collection.

[0093] When the second material level detector detects that the pure cigarette collector 4 is full or the second position detector detects that the pure cigarette collector 4 is not in position, the vibrating trough 6 stops moving, the alarm sounds and displays "Pure cigarette collector not in position" or "Pure cigarette collector full" on the display screen.

[0094] When the first material level detector detects that the waste collector 3 is full or the first positioning detector detects that the waste collector 3 is not in position, the drive mechanism 8 drives the first guide plate 9 to the second state, so that the first guide plate 9 and the second guide plate 11 close the bottom of the V-shaped hopper 13 to temporarily store the waste. At the same time, the alarm sounds and displays "waste collector full" or "waste collector not in position" on the display screen.

[0095] When the drive mechanism 8 drives the first guide plate 9 to be in the first state or the second state, the drive mechanism 8 can move back and forth along its extension direction.

[0109] Waste storage procedure: A V-shaped hopper 13 that can be opened and closed is installed below the screen in the front half of the vibrating trough 6 to temporarily store waste when the waste collector 3 is detached or full.

[0110] Pure cigarette storage procedure: A pure cigarette collector 4 is installed below the end of the vibrating groove 6. The vibrating groove 6 stops operating when the pure cigarette collector 4 is removed or when it is full, and the pure cigarettes are temporarily stored using the vibrating groove 6.

[0111] Waste collection steps: A rectangular waste collector 3 is placed below the V-shaped hopper 13 to collect waste dust.

[0112] Pure cigarette collection steps: A rectangular pure cigarette collector 4 is placed downstream of the vibrating trough 6 to collect pure cigarettes.

[0113] Preferably, the angle between the vibrating groove 6 and the horizontal plane is 15°, the front end of the vibrating groove 6 is at a high position, and the end of the vibrating groove 6 is at a low position.

[0114] Preferably, the screen has circular holes with a diameter of 3 mm.

[0115] Preferably, the compressed air is injected in a direction perpendicular to the horizontal plane downwards, so that powder and impurities in the waste cigarettes fall through the screen into the V-shaped hopper 13 or waste collector 3 below.

[0116] Preferably, the magnetic separator is a magnet 12, which is the same width as the vibrating groove 6 and is installed below the end of the vibrating groove 6, covering the forward movement of the cigarette stick for 10cm.

[0119] Waste collector 3 detection steps: An alarm is installed on top of the waste collector 3, and a first material level detector and a first position detector are installed on the side of the waste collector 3.

[0120] The first level detector is configured to detect the level status of the waste collector 3 and output a "hopper not full" or "hopper full" signal. The first position detector is configured to detect the position of the waste collector 3 and output a "position in" or "not in" signal. The control system receives signals from the first level detector and the second position detector, and only controls the type V hopper 13 to open when both a "position in" signal and a "hopper not full" signal are received simultaneously; otherwise, the type V hopper 13 remains closed. The alarm receives a second level detection signal and sounds a buzzer when a "hopper full" signal is received.

[0121] The detection steps for the clean cigarette collector 4 are as follows: An alarm is installed above the clean cigarette collector 4, and a second level detector and a second position detector are installed on the side of the clean cigarette collector 4.

The second position detector is configured to detect the position of the clean cigarette collector 4 and output a "position in" or "not in" signal.

[0122] The control system receives signals from the second level detector and the second arrival detector. It controls the vibrating trough 6 to vibrate only when it simultaneously receives both the "arrival" signal and the "hopper not full" signal; otherwise, it keeps the vibrating trough 6 stationary. The alarm receives a signal from the second level detector and sounds a buzzer when it receives the "hopper full" signal.
