The clamping cylinder 27 is moved on the cigarette holder support frame 26 by the clamping plate 29. The cigarette holder support frame 26 may be formed as a U-shaped groove, with the dimension of the U-shaped groove in the first direction being larger than the dimension of the cigarette holder 30 in the first direction. This is because a support and clamping assembly is provided to ensure the stability of the cigarette holder 30. The clamping cylinder 27 passes through the cigarette holder 30, allowing one side of the cigarette holder 30 to be tightly against the cigarette holder support frame 26, thus ensuring stable installation.

[0033] Preferably, such as Figure 1 and Figure 3As shown, in this embodiment, the cigarette rejection and recycling device may further include an alarm component, which is disposed opposite to the clamping cylinder 27 on both sides of the cigarette holder 30. The alarm component includes an alarm light 35, which consists of a green light 351, a red light 352, and a buzzer 353, used to indicate the clamping status and capacity of the cigarette holder. During use, if the device is in the normal cigarette recycling process, the green light 351 of the alarm light 35 remains constantly lit. If the clamping device is not working, i.e., the second piston rod 28 is in the retracted state, the red light 352 of the alarm light 35 flashes, prompting the operator to clamp the cigarette holder 30. If the device has reached the recycling limit position, i.e., the cigarette holder 30 has moved to the set position in both the first and second directions, the buzzer 353 of the alarm light 35 continuously emits a warning sound, prompting the operator to remove the cigarette holder 30.

[0034] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, the cigarette rejection and recycling device can also clamp a switch 36, which includes a start button 361 and a stop button 362. The start button 361 and the stop button 362 can respectively control the start and stop of the clamping cylinder 27.

[0035] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, a clamping plate 29 is provided at the end of the second piston rod 28 of the clamping cylinder 27 to ensure that the cigarette holder 30 is clamped in place.

[0036] Preferably, such as Figure 1 and Figure 2 As shown in the embodiment, the cross-sectional area of ​​the connecting channel 8 gradually decreases along the cigarette removal direction. This arrangement allows the falling position and falling posture of the cigarettes to be controlled, thereby enabling them to be arranged in an orderly manner within the cigarette holder 30.

[0037] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the cigarette rejection and recycling device may further include a first observation element 3 and a second observation element 4, which are respectively disposed at both ends of the conveyor belt 1. The first observation element 3 and the second observation element 4 may be, for example, a cigarette tobacco end camera and a cigarette filter end camera in the prior art, used to detect quality defects at the tobacco end and filter end of the cigarette. Qualified cigarette packs that pass the inspection will be wrapped with inner lining paper in subsequent processes.

[0038] The assembly process of the cigarette rejection and recycling device is as follows: First, the conveyor belt 1 is used to transport groups of cigarettes. The connecting channels 8 of the rejection cylinder 5 are located on both sides of the conveyor belt 1, used to reject and transport defective cigarettes 33. The conveyor belt 1 is horizontally set and driven by a motor. Multiple cigarette mold boxes 2 are set on the conveyor belt 1 for transporting cigarettes 32 to be inspected. The first observation piece 3 and the second observation piece 4 are respectively set on both sides of the conveyor belt 1 for detecting quality defects at the tobacco end and filter end of the cigarette. Qualified cigarette groups that pass the inspection will be wrapped with inner lining paper in subsequent processes. The rejection cylinder 5 is fixedly installed on the support plate on the side of the conveyor belt 1. The first piston rod 6 of the rejection cylinder 5 is horizontally set and extends towards the connecting channel 8. The rejection plate 7 is fixedly installed at the end of the first piston rod 6. The rejection plate 7 is set opposite to the connecting channel 8 so that the defective cigarettes 33 can be pushed into the connecting channel 8. Understandably, because the defective cigarettes 33 conveyed by the cigarette mold box 2 need to be pushed into the connecting channel 8, the bottom surface of the cigarette removal plate 7 should be higher than the bottom of the cigarette mold box 2 to avoid interference during cigarette removal and prevent it from being pushed into place. The cigarette holder 30 is adjusted in the first and second directions by the first adjustment assembly and the second adjustment assembly. Furthermore, the first support plate 18 of the first adjustment assembly is fixedly installed on the first nut 21 and the first slider 25, and the first nut 21 and the first slider 25 are always at the same height. Multiple screw holes are provided at both ends of the first support plate 18, and it is fixedly connected to the second nut 13 and the second slider 17 by bolts. The first lead screw 22 is horizontally arranged, with one end electrically connected to the first drive motor 19 through the first coupling 20, and the other end connected to the first bearing seat 23. The first nut 21 is disposed on the first lead screw 22. The first slide rail 24 is fixedly installed on the first support plate 18 by bolts and is provided with the first slider 25. In this embodiment, the first nut 21 is offset from the first slider 25 to make the first support plate 18 more stable when moving. Furthermore, the second support plate 9 and the third support plate 15 are both fixedly installed and perpendicular to the ground. The second lead screw 12 is vertically arranged and extends upwards, with one end electrically connected to the second drive motor 10 via the second coupling 11, and the other end connected to the second bearing seat 14. A second nut 13 is provided on the second lead screw 12. The second slide rail 16 is fixedly installed on the third support plate 15 by bolts, and a second slider 17 is provided on the second slide rail 16 to ensure that the tobacco holder 30 can rise and fall smoothly and avoid shaking. Finally, the tobacco holder support frame 26 is fixedly installed on the upper part of the first nut 21 and the first slider 25 by bolts to support and complete the left-side limit of the tobacco holder 30. The clamping cylinder 27 is fixedly installed on the tobacco holder support frame 26 and located on the side of the tobacco holder 30. The second piston rod 28 of the clamping cylinder 27 is horizontally arranged and extends towards the direction of the tobacco holder 30. The clamping plate 29 is fixedly installed at the end of the second piston rod 28. The clamping plate 29 is horizontally arranged, with one side facing the side of the cigarette holder 30.The clamping plate 29 has a sponge pad 34 on its working surface for elastically clamping cigarette holders with uneven sides. An alarm light 35 is located on the upper left side of the cigarette holder support frame 26. The alarm light 35 consists of a green light 351, a red light 352, and a buzzer 353, used to indicate the clamping status and capacity of the cigarette holder. A clamping switch 36 is also located on the upper left side of the cigarette holder support frame 26. The clamping switch 36 consists of a start button 361 and a stop button 362, used for electrically controlling the clamping and releasing of the clamping plate 29.

[0039] The operation of this cigarette rejection and recycling device is as follows: First, before recycling the rejected cigarettes, place the cigarette holder 30 on the cigarette holder support frame 26, ensuring that the first side of the cigarette holder 30 is against the inner wall of the cigarette holder support frame 26. Second, press the start button 361 of the clamping switch 36, which drives the second piston rod 28 of the clamping cylinder 27 to extend, causing the clamping plate 29 to press against the right side of the cigarette holder 30, thus fixing the position of the cigarette holder 30. At this time, the green light 351 of the alarm light 35 remains constantly lit. Third, the first drive motor 19 and the second drive motor 10 of the cigarette holder 30 start simultaneously, moving the cigarette holder 30 along the first and second directions to the designated position. At this time, the lower left corner of the cigarette holder 30 is directly opposite the outlet of the connecting channel 8. In the fourth step, the conveyor belt 1 continuously transports the cigarettes 32 to be inspected in the cigarette mold box 2 to the first observation piece 3 and the second observation piece 4 for cigarette quality inspection. If both are qualified cigarettes, the rejection component does not move, and the cigarettes continue to be transported forward to be wrapped with the inner lining paper. If either the first observation piece 3 or the second observation piece 4 detects a defective cigarette 33, after the cigarette mold box 2 moves to the position of the rejection mechanism, the rejection cylinder 5 of the rejection mechanism is activated, the first piston rod 6 drives the rejection plate 7 to extend, and quickly pushes the defective cigarette 33 out of the cigarette mold box 2, through the connecting channel 8 to the carrying cigarette holder 30. After the rejection plate 7 completes its action, it returns to its initial working position. Fifth, each time the system generates a cigarette rejection signal, the first drive motor 19 drives the first lead screw 22 to rotate, causing the first nut 21 and the cigarette holder 30 to move horizontally to a designated distance, ready to receive the next set of rejected cigarettes; Sixth, when the horizontal movement on the same layer reaches the set number of times, that is, when the first layer of space on the cigarette holder 30 is used up, the second drive motor 10 drives the second lead screw 12 to rotate, causing the second nut 13 and the cigarette holder 30 to move downward to a designated distance, and the second layer of space is used; Seventh, steps 5 and 6 are repeated until the horizontal movement distance and the vertical movement distance are both reached. When the distance reaches the set limit value, the buzzer 353 of the alarm light 35 will continuously emit a warning sound to indicate to the operator that the cigarette holder is full; in the eighth step, press the stop button 362 of the clamping switch 36, which will cause the second piston rod 28 of the clamping cylinder 27 to retract, driving the clamping plate 29 away from and releasing the cigarette holder 30. At this time, the green light 351 of the alarm light 35 will turn off and the red light 352 will flash, indicating to the operator that the cigarette holder 30 is not clamped; in the ninth step, the operator can remove the cigarette holder 30 from the cigarette holder support frame 26 through the cigarette holder handles 31 on both sides of the cigarette holder 30 for subsequent sorting and reuse.

[0040] This cigarette rejection and recycling device, through the cooperation of a cigarette rejection mechanism, a cigarette holder, and an adjustment mechanism, enables the rejection mechanism to remove defective cigarettes. The cigarette holder, driven by a first adjustment component and a second adjustment component, can adjust its position in a first and a second direction, thereby connecting with the channel to achieve the collection and orderly arrangement of cigarettes. The device has a compact overall structure, is easy to assemble, and can achieve automated cigarette rejection and recycling. After rejection, the cigarettes are arranged in an orderly manner for sorting and reuse, effectively reducing the amount of waste cigarettes, minimizing the waste of raw materials, and saving production costs.
