This process is usually achieved through physical methods, such as using screening, air classification or optoelectronic sorting and other technical means to distinguish according to the differences in the shape, size, density, color, etc. of tobacco shreds and paper scraps. The purpose of sorting is to improve the recycling rate of tobacco shreds, reduce environmental pollution caused by waste, and ensure that the recycled tobacco shreds can meet the quality standards for reprocessing or use. By optimizing sorting technologies and equipment, as well as implementing standardized operating procedures and quality control measures, the sorting efficiency and accuracy can be further improved, and the maximum utilization of resources can be achieved. In the current sorting process of tobacco shreds and paper scraps, a significant challenge is that the tiny paper scraps after crushing are frequently mixed with tobacco shreds, which greatly weakens the separation effect and becomes the main obstacle to improving the sorting quality and purity. This problem not only affects the quality of the recycled tobacco shreds, but may also have an adverse impact on the subsequent processing process.

Specific embodiments

[0021] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1 - 7 , the present utility model provides a technical solution:

[0024] A sorting mechanism for waste tobacco shreds and paper scraps, comprising a sorting machine body 1, a tobacco shred input device 3, a tobacco shred cutting device 4 and a recycling bin 2, further comprising an absorption pipe 5. The absorption pipe 5 is located on the sorting machine body 1, and is used to separate the fine paper scraps in the tobacco shreds when screening the tobacco shreds and paper scraps.

[0025] A sorting component 6 is arranged on the sorting machine body 1, and the absorption pipe 5 is arranged on the sorting component 6. The sorting component 6 is used to control the absorption pipe 5 to generate negative pressure during screening, so as to recycle the paper scraps scattered during the vibration screening process.

[0026] The sorting component 6 includes a screening part 7 arranged on the sorting machine body 1. The cut waste tobacco shreds are screened by the screening part 7. A driving part 8 is arranged on the screening part 7 to provide power for the operation of the screening part 7. An absorption part 9 is arranged on the screening part 7, and the absorption part 9 drives the absorption pipe 5 to collect the fine paper scraps in the waste tobacco shreds.

[0027] The advantage of arranging the sorting component 6 is that it adopts a multi-layer sieve plate structure. The sieve plate one 72 is used to filter tobacco shreds, and the sieve holes 75 are relatively large. The sieve plate two 74 is used to filter tobacco dust, and the sieve holes 75 are relatively small. This design can effectively separate tobacco shreds from fine shredded cigarette paper and tobacco dust, thereby improving the effect of tobacco shred sorting. Moreover, during the sorting process, the negative pressure in the absorption pipe 5 is used to absorb the fine paper scraps scattered during the tobacco shred screening process, so that they are separated from the tobacco shreds, thereby greatly improving the effect of tobacco shred sorting.

[0028] The screening part 7 includes a mounting frame 71 arranged on the sorting machine body 1. A sieve plate one 72 is slidably arranged in the mounting frame 71. A plurality of connecting rods 73 are arranged on one side of the sieve plate one 72. A sieve plate two 74 is arranged on the connecting rods 73. Sieve holes 75 are formed on both the sieve plate one 72 and the sieve plate two 74. A plurality of separating blocks 76 are arranged on the sieve plate one 72.

[0029] The advantage of arranging the screening part 7 is that it uses a multi-layer sieve plate structure to screen tobacco shreds. The multi-layer sieve plates can realize multi-stage screening of tobacco shreds. Each layer of sieve plate can intercept paper scraps within a certain particle size range. This hierarchical screening method can significantly improve the screening efficiency and ensure the accuracy and reliability of the screening results. At the same time, the arrangement of the separating blocks 76 can quickly disperse the tobacco shreds and paper scraps, improving the screening efficiency.

[0030] The driving member 8 includes a plurality of rotating shafts 81 rotatably arranged on the mounting frame 71. Push blocks 82 are arranged at both ends of the rotating shaft 81. A synchronous pulley 84 is arranged at the end of the rotating shaft 81. A synchronous belt 85 is arranged on the synchronous pulley 84. A protective shell 86 is arranged at the position of the synchronous belt 85 on the mounting frame 71. A driving motor 83 is arranged on the protective shell 86. The output end of the driving motor 83 is connected to the rotating shaft 81. Positioning plates 87 are arranged on both sides of the mounting frame 71. A plurality of return springs 88 are arranged on the positioning plates 87. The return springs 88 are connected to the first sieve plate 72.

[0031] The absorbing member 9 includes a plurality of recovery bins 91 arranged on the first sieve plate 72. A collection bin 92 is arranged on the first sieve plate 72. The collection bin 92 is communicated with the plurality of recovery bins 91. The recovery bins 91 are connected to the absorption tube 5. A push rod 93 is arranged on the second sieve plate 74. A piston plate 94 is arranged at the end of the push rod 93. A pneumatic chamber 95 is arranged on the mounting frame 71. The piston plate 94 and the push rod 93 are slidably connected to the pneumatic chamber 95. A one-way air outlet valve 96 is arranged on the pneumatic chamber 95. A one-way air inlet valve 97 is arranged on the pneumatic chamber 95. An air guide pipe 98 is arranged on the one-way air inlet valve 97. An isolation chamber 99 is arranged on the collection bin 92. The isolation chamber 99 is communicated with the air guide pipe 98 and the collection bin 92. The air guide pipe 98 is a flexible pipe.

[0032] The advantage of arranging the absorbing member 9 is that it can separate the fine paper scraps in the cut tobacco from the cut tobacco through negative pressure air flow. If the fine paper scraps in the cut tobacco are not removed in time, they will exist in the cut tobacco as impurities, affecting the overall quality of the cut tobacco. By absorbing these paper scraps through the air flow, the impurity content in the cut tobacco can be significantly reduced, and the purity of the cut tobacco can be improved.

[0033] The sieve holes 75 on the first sieve plate 72 are waist-shaped holes. During the vibration screening process, the long-strip design of the waist-shaped holes may help reduce the impact force between the cut tobacco and the sieve plate. Compared with circular or square sieve holes 75, the waist-shaped holes may provide a smoother transition path when the cut tobacco passes through, thereby reducing the damage to the cut tobacco structure. Therefore, the design of the waist-shaped holes helps to maintain the integrity and quality of the cut tobacco. By reducing the mechanical damage and fragmentation during the screening process, it can ensure that the cut tobacco maintains good physical properties and sensory qualities during subsequent processing and use.

[0034] In use, the staff first starts the drive motor 83, and then puts the whole waste cigarette into the tobacco input device 3. The waste cigarette is cut by the tobacco cutting device 4 and sent onto the first sieve plate 72. At the same time, the drive motor 83 works to drive the rotating shaft 81 to rotate. The rotation of the rotating shaft 81 drives multiple rotating shafts 81 to rotate synchronously through the synchronous pulley 84 and the synchronous belt 85. Driven by the rotating shaft 81, multiple pushing blocks 82 rotate synchronously and push the first sieve plate 72 and the second sieve plate 74 to move. At the same time, under the push of the positioning plate 87 and the return spring 88, the first sieve plate 72 and the second sieve plate 74 make reciprocating up and down movements, thereby driving the waste tobacco shreds to jump on the first sieve plate 72, so that the tobacco passes through the sieve holes 75 on the first sieve plate 72 and falls onto the second sieve plate 74.

[0035] When the second sieve plate 74 makes reciprocating up and down movements, it drives the push rod 93 and the piston plate 94 to move in the pneumatic chamber 95. When the piston plate 94 rises, a negative pressure is formed in the pneumatic chamber 95, and the paper scraps between the first sieve plate 72 and the second sieve plate 74 follow the air flow into the absorption tube 5 and then enter the collection bin 92 through the recovery bin 91. At the same time, the setting of the one-way air outlet valve 96 and the one-way air inlet valve 97 makes it so that the gas does not re-enter the collection bin 92 when the piston plate 94 descends, and the setting of the isolation chamber 99 makes it so that the paper scraps do not follow the air flow into the pneumatic chamber 95.

[0036] Embodiment 2

[0037] Please refer to Figure 8 , the present invention provides a technical solution:

[0038] Different from Embodiment 1, a powder storage bin 10 is provided on the mounting frame 71. The advantage of setting the powder storage bin 10 is that it can collect the tobacco shreds screened out by the second sieve plate 74, which is convenient for subsequent processing.
