The output end of the receiving conveyor 1 is connected to the input end of the first impurity removal mechanism 2. The receiving conveyor 1 is used to receive waste at the impurity outlet and convey the waste to the first impurity removal mechanism 2, and the first impurity removal mechanism 2 performs preliminary impurity removal. The input end of the second conveyor 3 is connected to the output end of the first impurity removal mechanism 2, and the output end of the second conveyor 3 is connected to the input end of the processing mechanism 4.

[0024] In this embodiment, the first impurity removal mechanism 2 includes a second shell 21 and an adsorption assembly 22. The second shell 21 is provided with a first mounting groove 211. The adsorption assembly 22 includes a cover plate 221, a mounting bar 222 and a plurality of magnetic parts 223. One end of the cover plate 221 is rotatably mounted on the top of the first mounting groove 211. The mounting bar 222 is fixedly mounted on the cover plate 221. A plurality of magnetic parts 223 are fixedly mounted on the mounting bar 222. The specific magnetic parts 223 are magnets. It should be noted that the magnetic parts 223 are arranged on the mounting bar 222 at equal intervals. The output end of the receiving conveyor 1 is located in the first mounting groove 211, and the magnetic part 223 is located above the output end of the receiving conveyor 1. In the process of the receiving conveyor 1 conveying the waste material into the first mounting groove 211, when the waste material passes through the magnetic part 223, the magnetic part 223 absorbs the metal particles, fragments, etc. in the waste material.

[0025] In this embodiment, the receiving conveying member 1 includes a first conveying belt 11. Specifically, a second mounting groove 212 is provided on one side of the first mounting groove 211. The first mounting groove 211 is connected to the second mounting groove 212. The first conveying belt 11 is arranged in the second mounting groove 212. A plurality of first conveying teeth 111 are arranged on the first conveying belt 11. A second conveying wheel 23 is installed in the first mounting groove 211. A plurality of second conveying teeth 231 are arranged on the second conveying wheel 23. The first conveying teeth 111 and the second conveying teeth 231 are arranged alternately. When the second conveying wheel 23 is working, the second conveying teeth 231 cooperate with the first conveying teeth 111 to loosen the block-shaped and ball-shaped tobacco so that the loosened tobacco can be torn off later, thereby further improving the recovery efficiency.

[0026] In this embodiment, the processing mechanism 4 includes a first housing 41 and a differential wheel assembly. A processing chamber 411 is provided in the first housing 41.

The input end of the second conveyor belt 31 is located below the guide plate 213. The output end of the second conveyor belt 31 is located at the upper end of the processing chamber 411. The waste material passing through the first impurity removal mechanism 2 falls from the guide plate 213 below the first mounting groove 211 onto the second conveyor belt 31. The second conveyor belt 31 transports the waste material into the processing chamber 411. The differential wheel assembly processes the long tobacco shreds in the waste material.

[0027] Specifically, the differential wheel assembly includes a first rotating wheel 421 and a second rotating wheel 422. A plurality of convex teeth 423 are provided on the first rotating wheel 421 and the second rotating wheel 422. The rotation direction of the first rotating wheel 421 is opposite to that of the second rotating wheel 422.

The convex teeth 423 of the first rotating wheel 421 and the second rotating wheel 422 cooperate and rotate at a differential speed to tear off the long tobacco in the waste material, so that the second impurity removal mechanism 5 can recover the tobacco.

[0028] It should be noted that the axial gaps between the plurality of protruding teeth 423 along the first rotor 421 or the second rotor 422 can be set according to the length of the required tobacco. If longer tobacco is required, the distance between the protruding teeth 423 can be shortened; if longer tobacco is required, the distance between the protruding teeth 423 can be lengthened.

[0029] In this embodiment, the second impurity removal mechanism 5 is arranged in the first shell 41. Specifically, the second impurity removal mechanism 5 includes a vibration groove 51 and an air selection pipe 52. The vibration groove 51 is located below the processing chamber 411 and is used to transport waste to the outside. In this embodiment, a waste box 6 is provided on one side of the first shell 41. One end of the vibration groove 51 passes through the first shell 41 and is located above the waste box 6. When the vibration groove 51 is working, the waste in the processing chamber 411 is transported to the waste box 6. In this embodiment, the air selection pipe 52 is located on one side of the conveying direction of the vibration groove 51, and the suction end of the air selection pipe 52 is located above the vibration groove 51. During the conveying process of the vibration groove 51, the air selection pipe 52 sucks in and recycles the light tobacco shreds torn in the vibration groove 51.

[0030] It should be noted that the end of the air selection duct 52 is connected to the original air duct, and no additional negative pressure source is required. The recovered light tobacco is directly returned to the original conveying channel and merged with the tobacco in the original conveying channel for the next tobacco processing process.

[0031] In this embodiment, a first conveying wheel 53 is disposed below the differential wheel assembly, and a plurality of blades are disposed on the first conveying wheel 53 to achieve the purpose of evenly conveying the waste.

[0032] In this embodiment, a first cover 32 is provided at one end of the second conveying member 3 close to the first impurity removing mechanism 2. The first cover 32 is provided to prevent the waste material falling into the first conveyor belt 11 from splashing around. A second cover 33 is provided at one end of the second conveying member 3 close to the processing mechanism 4. The second cover 33 is provided to prevent the waste material entering the processing chamber 411 from splashing around.

[0033] The working principle of the utility model is as follows:

[0034] First, the waste in the outlet falls on the first conveyor belt 11, and the first conveyor belt 11 conveys the waste to the first installation slot 211. In this process, when the waste passes through the magnetic member 223, the magnetic member 223 absorbs metal particles, fragments, etc. in the waste. After the waste enters the first installation slot 211, the second conveying teeth 231 cooperate with the first conveying teeth 111 to loosen the block and ball tobacco.

[0035] Then, the waste falls onto the second conveyor belt 31 through the guide plate 213 at the bottom of the first mounting groove 211. The second conveyor belt 31 conveys the waste to the processing chamber 411. After the waste enters the processing chamber 411, the convex teeth 423 of the first rotating wheel 421 and the second rotating wheel 422 cooperate and rotate differentially to tear off the long tobacco shreds in the waste, and then pass through the first conveying wheel 53 and fall onto the vibration groove 51.

[0036] Finally, the vibration trough 51 works to transport the waste into the waste box 6. During this process, the air selection duct 52 sucks in the light tobacco torn in the vibration trough 51 for recycling, thereby realizing tobacco recycling, and the remaining waste enters the waste box 6 for storage.
