Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a cigarette butt sorting and recycling device. Background Technology

[0002] Cigarette butts, as a type of recyclable waste, mainly consist of three parts: the tobacco shreds, containing unburned tobacco components, can be processed to remake tobacco sheets or extract effective substances for other applications; the filter tip, made of cellulose acetate filter rods, can be used in the preparation of pharmaceuticals, cosmetics, food additives, and chemical raw materials after professional purification; and the packaging paper covering the filter tip, after deinking, can be used as recycled pulp in the paper industry. However, traditional separation processes mainly rely on manual cutting with a utility knife along the axial direction of the cigarette butt to separate the tobacco shreds, filter tip, and packaging paper. This process is slow, and the cigarette butts release irritating odors into the environment during operation, affecting the health and safety of operators. Furthermore, operators may suffer hand injuries due to blade slippage. Summary of the Invention

[0034] (III) Beneficial Effects

[0035] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0036] 1. In this utility model, the two cigarette butt pressure rollers can squeeze the cigarette butt, making the tobacco inside the cigarette butt loose. By causing the sieve plate to vibrate, the tobacco is separated from the cigarette butt. After separation, the tobacco falls along the sieve plate into the tobacco recycling box.

[0037] The cutting structure can cut the surface of cigarette butts, separating the wrapping paper from the filter and conveying it into a guide tube. After the filter and wrapping paper are discharged from the guide tube, they fall naturally. By positioning the outlet of one of the air ducts below the guide tube on the side away from the cutting machine, and with the outlet facing the guide section, the lighter wrapping paper is blown towards the guide section and discharged into the collection box along the guide section and discharge channel when the filter and wrapping paper fall. The filter falls naturally under its own weight and is discharged into another collection box through another discharge channel, making it convenient for workers to collect the filter and wrapping paper separately.

[0038] Second, in this utility model, the two cigarette butt pressure rollers can squeeze the cigarette butts, making the tobacco inside the cigarette butts loose; the belt support shaft supports the conveyor belt, preventing the conveyor belt from deforming when the cigarette butt pressure rollers squeeze the cigarette butts on the conveyor belt. At the same time, the belt support shaft makes rolling contact with the top of the inner wall of the conveyor belt, thereby reducing the friction between the belt support shaft and the conveyor belt.

[0039] Third, in this utility model, the air outlet mesh on the air supply chamber evenly delivers the air from the inner cavity of the air supply chamber, blowing the filter and packaging paper that have been cut and separated on the upper surface of the air supply chamber. During the blowing process, the heavier filter is located at the bottom, while the lighter paper falls on top of the filter, so that the air outlet of the air outlet pipe blows the paper into the guide part.

[0040] Fourth, in this utility model, the set buffer sleeve can buffer the vibration and avoid direct contact between the clamping frame and the sleeve cover. When the clamping frame vibrates, it will generate a lot of noise with the sleeve cover. Attached Figure Description

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] Example 1

[0053] like Figures 1-9 As shown, a cigarette butt sorting and recycling device includes a sleeve cover 1, a cigarette butt conveyor, and a cutting structure. The sleeve cover 1 is fitted onto the cigarette butt conveyor and the cutting structure. The sleeve cover 1 prevents odors and cigarette butt fragments from spreading to the surrounding environment during the conveying, squeezing, and cutting of the cigarette butts. A cigarette butt pressure roller 2 is rotatably connected to the cigarette butt conveyor. A screening plate 3 is installed below the output end of the cigarette butt conveyor. Specifically: Figure 3 and Figure 4As shown, the cigarette butt conveyor includes two side baffles 8 and a second roller 81. Both side baffles 8 are fixedly connected to the sleeve cover 1. The two sides of the two second rollers 81 are rotatably connected to the two side baffles 8 respectively. The two second rollers 81 are fitted with the same conveyor belt 82.

[0054] One end of the screening plate 3 is located below the output end of the conveyor belt 82;

[0055] The two cigarette butt pressing rollers 2 are rotatably connected to the two side baffles 8 on both sides respectively. The two cigarette butt pressing rollers 2 are located above the conveyor belt 82, and there is a gap between the bottom of the cigarette butt pressing rollers 2 and the top of the conveyor belt 82 for the cigarette butt to pass through. The two cigarette butt pressing rollers 2 can squeeze the cigarette butt, making the tobacco inside the cigarette butt loose.

[0056] One of the second rollers 81, part of the conveyor belt 82, and part of the side baffle 8 extend out of the sleeve cover 1 to facilitate workers to lay cigarette butts on the conveyor belt 82.

[0057] Furthermore, a first toothed disc 83 is fixedly sleeved on the same side of both cigarette butt pressing rollers 2. The two first toothed discs 83 are connected by a first chain 84. When one of the cigarette butt pressing rollers 2 rotates, the other cigarette butt pressing roller 2 is driven to rotate in the same direction under the cooperation of the first toothed disc 83 and the first chain 84.

[0058] A docking shaft 801 is rotatably connected to the side baffle 8 near the first gear 83. A first driven gear 85 and a second gear 86 are fixedly sleeved on the docking shaft 801. A first gear 87 is fixedly sleeved on one of the second rollers 81. The first gear 87 meshes with the first driven gear 85.

[0059] One of the cigarette butt pressure rollers 2 is fixedly fitted with a second toothed disc 86, and the two second toothed discs 86 are connected by a second chain 88.

[0060] A first motor 89 is installed on one of the side baffles 8, and the rotating shaft of the first motor 89 is fixedly connected to one of the second rollers 81.

[0061] Specifically, the first motor 89 drives the second roller 81 to rotate clockwise via the rotating shaft. At the same time, the first gear 87 fixedly sleeved on the second roller 81 also rotates synchronously. Under meshing action, the first driven gear 85 rotates counterclockwise, which in turn drives the docking shaft 801 and the second toothed disc 86 to rotate counterclockwise. Under the action of the second chain 88, the cigarette butt pressing roller 2 with the second toothed disc 86 also rotates counterclockwise. In the cooperation of the first toothed disc 83 and the first chain 84, it drives another cigarette butt pressing roller 2 to rotate in the same direction, so that the cigarette butt pressing roller 2 can squeeze the cigarette butts on the conveyor belt 82.

[0062] Furthermore, two positioning shafts 802 are fixedly connected to the side of the two side baffles 8 that are close to each other. The two positioning shafts 802 on the same axis are rotatably connected to the same belt support shaft 810. The belt support shaft 810 is in rolling contact with the top of the inner wall of the conveyor belt 82 and is located directly below the cigarette butt pressure roller 2.

[0063] Specifically, when the conveyor belt 82 is in operation, it will drive the belt support shaft 810 to rotate, thereby reducing the friction between the belt support shaft 810 and the conveyor belt 82. When the cigarette butt moves into the gap between the cigarette butt pressure roller 2 and the conveyor belt 82, the cigarette butt pressure roller 2 will squeeze the cigarette butt on the conveyor belt 82. At the same time, the belt support shaft 810 below the conveyor belt 82 will support the conveyor belt 82 to prevent the conveyor belt 82 from deforming when the cigarette butt pressure roller 2 squeezes the cigarette butt on the conveyor belt 82.

[0064] The sieve plate 3 is installed on the inner wall of the sleeve cover 1, specifically as follows: [The text abruptly ends here, likely due to an incomplete sentence or missing information.] Figure 3 and Figure 5 The sleeve cover 1 has insertion interfaces on both sides. The inner walls of the two insertion interfaces are fitted with buffer rubber sleeves 101. The two buffer rubber sleeves 101 are inserted into the same snap-fit ​​frame 102. The inner walls of the snap-fit ​​frame 102 are symmetrically provided with screen plate clamps 103. The screen plate clamps 103 are inclined. The two sides of the sieve plate 3 are integrally provided with anti-side leakage plates 301. The two anti-side leakage plates 301 are provided with alignment insertion ports 3011. The sieve plate 3 is snapped into the screen plate clamps 103 through the alignment insertion ports 3011. After snapping, the sieve plate 3 is also inclined. The high end of the sieve plate 3 is located below the output end of the conveyor belt 82. The anti-side leakage plates 301 can prevent cigarette butts on the sieve plate 3 from leaking out from the side of the sieve plate 3.

[0065] The conveyor belt 82 conveys the squeezed cigarette butts to the sieve plate 3 and moves along the sieve plate 3. The clamping frame 102 is equipped with a vibration motor 10. The vibration motor 10 can vibrate the sieve plate 3 through the clamping frame 102, so that the sieve plate 3 vibrates, so as to separate the tobacco and cigarette butts.

[0066] When the vibration motor 10 vibrates, the vibration can be buffered by the buffer sleeve 101, which prevents the clamping frame 102 from directly contacting the sleeve cover 1. When the clamping frame 102 vibrates, it generates a lot of noise with the sleeve cover 1.

[0067] Furthermore, such as Figure 3 As shown, a tobacco recycling frame 11 is placed inside the sleeve cover 1. After the tobacco is separated from the cigarette butts, the tobacco falls into the tobacco recycling frame 11 along the sieve plate 3. Figure 2As shown, a transparent plate 12 is detachably installed on one side of the sleeve cover 1. The transparent plate 12 allows staff to observe the tobacco collection. The transparent plate 12 is located on one side of the tobacco recycling box 11. When the tobacco recycling box 11 is full, the staff can remove the transparent plate 12 from the sleeve cover 1 to replace the tobacco recycling box 11.

[0068] like Figure 3 and Figure 5 As shown, the cutting structure includes a cutting machine box 4. The lower end of the sieve plate 3 is connected to the feed inlet of the cutting machine box 4. A spiral conveying rod 41 and two first rotating rollers 42 are rotatably connected to the cutting machine box 4. Each of the two first rotating rollers 42 is equipped with a cutting blade 43, and the cutting blades 43 on the two first rotating rollers 42 are arranged opposite to each other to facilitate the cutting of cigarette butts. The spiral conveying rod 41 is located below the two first rotating rollers 42.

[0069] Furthermore, such as Figure 6 As shown, the cutting blade 43 is spiral, and multiple cutting blades 43 are arranged circumferentially on the roller wall of each first rotating roller 42;

[0070] Two first rollers 42 are each fixedly fitted with a second gear 44, and the two second gears 44 mesh with each other. A second driven gear 45 is fixedly fitted at one end of the spiral conveyor rod 41 near the second gear 44. An adjustable gear 46 is rotatably connected to the side of the cutting machine box 4 near the second gear 44. The second driven gear 45 and one of the second gears 44 mesh with the adjustable gear 46. When the second gear 44 rotates, the second driven gear 45 can be driven to rotate through the adjustable gear 46 under the meshing action, thereby driving the spiral conveyor rod 41 to rotate.

[0071] like Figure 3 As shown, a second motor 47 is installed inside the sleeve cover 1, and the rotating shaft of the second motor 47 is rotatably connected to one of the first rotating rollers 42.

[0072] The cigarette butts on the sieve plate 3 flow down the lower end of the sieve plate 3 to the feed inlet of the cutting machine box 4 and fall onto the first rotating roller 42. The second motor 47 drives the first rotating roller 42 to rotate counterclockwise through the rotating shaft. Under the meshing action of the two second gears 44, the other first rotating roller 42 rotates clockwise, thereby cutting the surface of the cigarette butts through the cutting blade 43, separating the packaging paper from the filter tip. The cut cigarette butts fall to the bottom of the inner cavity of the cutting machine box 4 and are conveyed along the discharge port of the cutting machine box 4 by the spiral conveyor rod 41.

[0073] like Figure 1 , Figures 6-9As shown, a sleeve cover 1 extends from one side of the cutting structure and is fitted with a wind cover 5. The discharge port of the cutting machine box 4 is connected to a guide pipe 6, and a uniform air structure is set in the guide pipe 6.

[0074] A fan 7 is installed at the bottom of the inner cavity of the fan shroud 5. The fan 7 has two air outlets, one of which is located below the guide pipe 6 on the side away from the cutting machine box 4, and the other air outlet is connected to the uniform air structure.

[0075] Furthermore, the uniform air structure is an air supply chamber 9, the bottom of which is fixedly connected to the bottom of the inner cavity of the guide pipe 6, and the side wall of the air supply chamber 9 is in contact with the inner side wall of the guide pipe 6.

[0076] like Figure 8 As shown, the upper surface of the air supply chamber 9 is inclined and is provided with an air outlet mesh 901. The upper surface of the air supply chamber 9 is connected to the discharge port of the cutting machine box 4. The spiral conveyor rod 41 conveys the cut cigarette butts along the discharge port of the cutting machine box 4, and they fall onto the upper surface of the air supply chamber 9 through the discharge port of the cutting machine box 4, and flow inclinedly along the upper surface of the air supply chamber 9.

[0077] Furthermore, a guide part 51 is provided on one side of the wind hood 5, a discharge port is provided at the bottom of the wind hood 5, and a partition 52 is fixedly connected to the inner wall of the wind hood 5. The bottom of the partition 52 extends out to the discharge port and divides the discharge port into two discharge channels 53.

[0078] Collection boxes 54 are placed directly below both discharge channels 53.

[0079] Furthermore, the blower 7 is equipped with two air outlet pipes 71. The air outlet of one of the air outlet pipes 71 is connected to the air supply chamber 9. The blower 7 discharges air into the inner cavity of the air supply chamber 9 through one of the air outlet pipes 71, and evenly delivers the air from the inner cavity of the air supply chamber 9 through the air outlet mesh 901 on the air supply chamber 9. This blows the filter and packaging paper that have been cut and separated on the upper surface of the air supply chamber 9. During the blowing process, the heavier filter is located at the bottom, while the lighter paper falls on top of the filter, so that the air outlet of the other air outlet pipe 71 can blow the paper into the guide part 51. An electric valve 72 is installed on the air outlet pipe 71 connected to the air supply chamber 9. The blower 7 and the electric valve 72 are connected to the external terminal via signal transmission. The electric valve 72 can control the air volume of the corresponding air outlet pipe 71, thereby controlling the air pressure inside the air supply chamber 9 and preventing the air discharged from the air outlet mesh 901 from blowing away the filter and packaging paper due to excessive air pressure.

[0080] After the filter tip and packaging paper are discharged from the guide tube 6, they will fall naturally. The outlet of another air outlet 71 is located below the side of the guide tube 6 away from the cutting machine box 4, and the outlet of the air outlet 71 is set towards the guide part 51. Thus, when the filter tip and packaging paper fall, the lightweight packaging paper is blown towards the guide part 51 and discharged into the collection box 54 along the guide part 51 and the discharge channel 53, while the filter tip falls naturally under its own weight and is discharged into another collection box 54 through another discharge channel 53.

[0081] In summary, the workflow of this utility model is as follows:

[0082] Workers lay the dried cigarette butts onto the conveyor belt 82. The first motor 89 drives the second roller 81 to rotate clockwise via the rotating shaft. At the same time, the first gear 87 fixedly mounted on the second roller 81 also rotates synchronously. Under the meshing action, the first driven gear 85 rotates counterclockwise, which drives the docking shaft 801 and the second toothed disc 86 to rotate counterclockwise. Under the action of the second chain 88, the cigarette butt pressure roller 2 with the second toothed disc 86 also rotates counterclockwise. With the cooperation of the first toothed disc 83 and the first chain 84, it drives another cigarette butt pressure roller 2 to rotate in the same direction, so that the cigarette butt pressure roller 2 can squeeze the cigarette butts on the conveyor belt 82.

[0083] The conveyor belt 82 conveys the squeezed cigarette butts to the sieve plate 3 and moves along the sieve plate 3. The clamping frame 102 is equipped with a vibration motor 10. The vibration motor 10 can vibrate the sieve plate 3 through the clamping frame 102, so that the sieve plate 3 vibrates, so as to separate the tobacco shreds from the cigarette butts. After the tobacco shreds are separated from the cigarette butts, the tobacco shreds fall into the tobacco shreds recycling frame 11 along the sieve plate 3.

[0084] The cigarette butts on the sieve plate 3 flow along the lower end of the sieve plate 3 to the feed inlet of the cutting machine box 4 and fall onto the first rotating roller 42. The second motor 47 drives the first rotating roller 42 to rotate counterclockwise through the rotating shaft. Under the meshing action of the two second gears 44, the other first rotating roller 42 rotates clockwise, thereby cutting the surface of the cigarette butts through the cutting blade 43, separating the packaging paper from the filter tip. The cut cigarette butts fall to the bottom of the inner cavity of the cutting machine box 4. The spiral conveyor rod 41 conveys the cut cigarette butts along the discharge port of the cutting machine box 4, and they fall onto the upper surface of the air supply chamber 9 through the discharge port of the cutting machine box 4, and flow at an angle along the upper surface of the air supply chamber 9.

[0085] The blower 7 discharges air into the inner cavity of the air chamber 9 through one of the air outlet pipes 71, and evenly distributes the air from the inner cavity of the air chamber 9 through the air outlet mesh 901 on the air chamber 9. This blows the filter tip and packaging paper that have been cut and separated on the upper surface of the air chamber 9. During the blowing process, the heavier filter tip is located at the bottom, while the lighter paper falls on top of the filter tip. When the filter tip and packaging paper are discharged from the guide pipe 6, they will fall naturally. The outlet of the other air outlet pipe 71 is located below the side of the guide pipe 6 away from the cutting machine box 4, and the outlet of the air outlet pipe 71 is set towards the guide part 51. Thus, when the filter tip and packaging paper fall, the lighter packaging paper is blown towards the guide part 51 and discharged along the guide part 51 and the discharge channel 53 into the collection box 54, while the filter tip falls naturally under its own weight and is discharged into another collection box 54 through another discharge channel 53.
