Description

Technical Field

[0001] This invention relates to the field of tobacco recycling equipment technology, and more specifically to a tobacco shred recycling device. Background Technology

[0002] During cigarette manufacturing, a certain amount of cigarettes that do not meet production standards are generated. To improve the utilization rate of cigarette raw materials, the tobacco from these non-compliant cigarettes needs to be recycled. The recycled tobacco must not contain impurities such as cigarette paper or tipping paper, as these impurities not only affect the purity of the tobacco but also its reuse.

[0003] The existing technology uses a straight-line cutting method to cut the cigarette paper along its axis, and then uses a screening mechanism to separate the tobacco from the outer shell of the cigarette, thereby separating and recycling the tobacco. However, if the cutting point happens to be the joint of the cigarette paper, paper scraps or strips that are separated from the outer shell of the cigarette will be cut out. These paper scraps or strips are difficult to separate from the tobacco and will directly affect the reuse of the recycled tobacco.

[0004] Therefore, this application provides a new tobacco shred recycling device to improve the purity of tobacco shred recycling. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a tobacco shred recycling device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a tobacco shred recycling device, comprising:

[0007] frame;

[0008] The feeding hopper, located on the frame, is used to store cigarettes to be recycled;

[0009] The dispensing roller includes a rotating roller and a picking drum disposed on the rotating roller. The outer surface of the picking drum is provided with uniformly distributed adsorption grooves for adsorbing individual cigarettes along its axial direction.

[0010] A feeding mechanism is located below the distributing roller and is used to transport the cigarettes adsorbed by the picking drum one by one into the conveying pipe.

[0011] A cutting mechanism is used to cut the cigarettes conveyed in the delivery pipe and to spirally cut the outer shell of the cigarettes from the mouth to the mouthpiece.

[0012] The screening mechanism receives the outer shell and internal tobacco of the cigarette sticks cut by the cutting mechanism and screens them.

[0013] Furthermore, the cutting mechanism includes:

[0014] Multiple rotating disks are arranged axially along the front end of the conveying pipe to drive the cigarette screw forward.

[0015] A blade, disposed on the outer peripheral wall of at least one of the rotating disks, is used to cut the traveling cigarette.

[0016] Multiple first power components are used to drive the rotating disk to rotate respectively.

[0017] Furthermore, the vertical projections of the plurality of rotating disks onto the cigarette intersect the axis of the cigarette.

[0018] Furthermore, it also includes a suction mechanism, which includes a suction cylinder sleeved on the rotating roller and a negative pressure impeller connected to the suction cylinder. The negative pressure impeller is provided with a suction pipe for an external exhaust fan. The suction cylinder is provided with a suction groove, and the suction groove is provided with suction holes corresponding to the suction groove.

[0019] Furthermore, the suction tube is provided with a notch, and the bottom of the notch is provided with an arc plate for guiding the cigarette to the feeding mechanism.

[0020] Furthermore, the feeding mechanism includes a receiving trough for receiving cigarettes, an accelerating mechanism for conveying cigarettes in the receiving trough to a conveying pipe, and a support frame for mounting the accelerating mechanism. The accelerating mechanism includes an accelerating wheel for conveying cigarettes and a second power component for driving the accelerating wheel to rotate.

[0021] Furthermore, it also includes a first air-blowing hole disposed on one side of the receiving groove and an air-blowing block disposed on the side of the acceleration wheel away from the conveying pipe, which has a second air-blowing hole.

[0022] Furthermore, it also includes an adjustment mechanism for adjusting the position of the feeding mechanism, the adjustment mechanism including a mounting plate disposed below the support frame, a guide rail that slides with the mounting plate, and a third power component for driving the mounting plate to slide.

[0023] Furthermore, the screening device includes a screen for receiving the outer shell of the cigarette and the tobacco inside after being cut by the cutting mechanism, a conveyor belt disposed below the screen for receiving the tobacco, and a vibration motor for driving the screen to vibrate.

[0024] Furthermore, it also includes a mounting frame for installing the screen, and a guide cylinder is provided between the screen and the conveyor belt.

[0025] Compared with the prior art, the present invention has the following beneficial effects: By setting up a spiral cutting mechanism, when the cigarette moves to the cutting mechanism, the cutting mechanism drives the cigarette to move forward in a spiral. At the same time, the cutter of the cutting mechanism spirally cuts the cigarette shell along the direction from the mouth to the mouthpiece, which wraps the tobacco. This cutting method effectively solves the shortcomings of the straight cutting method, avoids the residue of cigarette paper scraps or strips in the tobacco, ensures the purity of the tobacco, and facilitates the reuse of the tobacco.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-15 .

[0045] The tobacco shred recycling device of the present invention is characterized in that it comprises:

[0046] Rack 1;

[0047] Feed hopper 2, located on the frame 1, is used to store cigarettes to be recycled;

[0048] The material distribution roller 3 includes a rotating roller 31 and a material taking drum 32 disposed on the rotating roller 31. The outer surface of the material taking drum 32 is provided with uniformly distributed adsorption grooves 33 for adsorbing individual cigarettes along its axial direction.

[0049] The feeding mechanism 4 is located below the distributing roller 3 and is used to transport the cigarettes adsorbed by the picking drum 32 one by one into the conveying pipe 41.

[0050] The cutting mechanism 5 is used to cut the cigarettes conveyed in the conveying pipe 41 and to spirally cut the outer shell of the cigarettes from the mouth to the mouthpiece.

[0051] The screening mechanism 6 receives the outer shell and internal tobacco of the cigarette stick cut by the cutting mechanism 5 and screens them.

[0052] In use, the cigarettes to be recycled are fed into the feeding hopper 2. Driven by the rotating roller 31, the adsorption groove 33 on the picking drum 32 carries the cigarettes. The feeding mechanism 4 transports the cigarettes carried by the distributing roller 3 to the conveying pipe 41. The cutting mechanism 5 spirally cuts the cigarettes conveyed by the conveying pipe 41 from the mouth to the mouthpiece. The cut cigarette shell and the tobacco inside are screened by the screening mechanism 6 to realize the recycling of cigarettes and improve the efficiency of cigarette recycling.

[0053] like Figure 3-5 As shown, in one embodiment, the cutting mechanism 5 includes:

[0054] Multiple rotating disks 51 are arranged axially along the front end of the conveying pipe 41 to drive the cigarette screw forward.

[0055] Blade 52, disposed on the outer peripheral wall of at least one of the rotating disks 51, is used to cut the moving cigarette stick;

[0056] Multiple first power components 53 are used to drive the rotating disk 51 to rotate respectively.

[0057] With this design, when the cigarette in the conveying pipe 41 is sent to the cutting mechanism 5, multiple first power components 53 drive the rotating disk 51 to carry the cigarette and convey it forward in a spiral. During the cigarette conveying process, the blade 52 set on at least one rotating disk 51 can cut the cigarette until the outer shell of the cigarette is spirally cut and the outer shell of the cigarette is completely separated from the tobacco inside.

[0058] Preferably, the number of rotating disks 51 is three, and the three rotating disks 51 are arranged in a triangular pattern. This design, by setting the number of rotating disks 51 to three, can stably carry the cigarette, ensure the stability of the cigarette during the cutting process, and facilitate the cutting of the cigarette.

[0059] Preferably, the bottom plate of the feeding bin 2 is inclined, and the feeding bin 2 is provided with an inclined plate 22 for guiding the cigarette sticks onto the bottom plate.

[0060] In one embodiment, the vertical projections of the plurality of rotating disks 51 onto the cigarette intersect the axis of the cigarette. This design, with the vertical projections of the rotating disks 51 of the blade 52 onto the cigarette intersecting the axis of the cigarette, allows the blade 52 to perform helical cutting of the cigarette during forward feeding. Compared to straight-line cutting, this cutting method does not produce cigarette outer shell debris during the cutting process, allowing for complete separation of the cigarette outer shell from the internal tobacco, thus avoiding waste of tobacco.

[0061] like Figure 3-4 As shown, preferably, it further includes adjustment mechanisms 54 for adjusting the positions of the rotating disks 51. The adjustment mechanism 54 includes a slide rail 541 mounted on the frame 1, a sliding plate 542 slidably mounted on the slide rail 541, and a fourth power component 543 for moving the sliding plate 542. The first power component 53 is mounted on the sliding plate 542. This design, by setting the adjustment mechanism 54, allows for adjustment of the positions of the three rotating disks 51 according to different cigarette sizes. This enables the three rotating disks 51 to move the cigarette forward during rotation, facilitating the cutting of the cigarette by the blades 52 mounted on the rotating disks 51.

[0062] like Figure 5 As shown, preferably, the front end of the conveying pipe 41 is provided with a clearance opening 411 for the rotating disk 51 to make way. With this design, by providing the clearance opening 411, while making way for the rotating disk 51, the side walls on both sides of the clearance opening 411 can also assist in positioning the cigarette to be cut, thereby ensuring the normal progress of cigarette cutting.

[0063] Preferably, the cutting mechanism 5 is provided with a housing 55. This design, by providing the housing 55, can prevent workers from accidentally touching the cutting mechanism 5 and ensure the normal operation of the cutting mechanism 5.

[0064] Preferably, a feeding drum 35 is provided above the distributing roller 3. This design can prevent cigarettes from accidentally entering and ensure that the feeding drum 32 can properly carry the cigarettes.

[0065] like Figure 6-10As shown, in one embodiment, a suction mechanism 7 is also included. The suction mechanism 7 includes a suction cylinder 71 sleeved on the rotating roller 31 and a negative pressure impeller 72 communicating with the suction cylinder 71. The negative pressure impeller 72 is provided with a suction pipe 73 for an external exhaust fan. The suction cylinder 71 is provided with a suction groove 74, and the adsorption groove 33 is provided with suction holes 75 corresponding to the suction groove 74. With this design, by providing a suction pipe 73 for an external exhaust fan, the negative pressure impeller 72 is in a negative pressure state. At this time, the suction groove 74 on the suction cylinder 71 communicating with the negative pressure impeller 72 performs suction, and the adsorption groove 33 is provided with suction holes 75 corresponding to the suction groove 74, so that the adsorption groove 33 can adsorb the cigarette, making it convenient for the picking drum 32 to carry the cigarette.

[0066] like Figure 6-10 As shown, in one embodiment, the suction duct 71 is provided with a notch 76, and the bottom of the notch 76 is provided with an arc plate 77 for guiding the cigarette to the feeding mechanism 4. With this design, by providing the notch 76, when the external feeding drum 32 carries the cigarette and rotates to the notch 76, the suction hole 75 has no suction force. At this time, the cigarette falls to the arc plate 77 below under the action of gravity, thereby facilitating the delivery of the cigarette to the feeding mechanism 4.

[0067] Preferably, the negative pressure impeller 72 is mounted on the frame 1, and the inside of the negative pressure impeller 72 is provided with a hollow cavity 78. The suction tube 71 is mounted on the negative pressure impeller 72, and the positions of the negative pressure impeller 72 and the suction tube 71 are fixed and do not rotate with the rotating roller 31. With this design, by fixing the positions of the negative pressure impeller 72 and the suction tube 71, the position of the notch 76 is also fixed. That is, when the picking drum 32 carries the cigarette and rotates to the position of the notch 76, the cigarette can fall onto the arc plate 77 below, which facilitates the delivery of the cigarette to the feeding mechanism 4.

[0068] Preferably, the device also includes a blower pipe 79 disposed at the notch 76 for blowing the cigarette off the adsorption tank 33. This design, by providing the blower pipe 79, prevents the cigarette from failing to fall from the adsorption tank when the feeding drum 32 rotates the cigarette to the position of the notch 76, thus assisting the cigarette in falling onto the lower arc plate 77.

[0069] Preferably, the side panel of the feeding hopper 2 is configured as a detachable baffle 21. This design facilitates the disassembly of the side panel of the feeding hopper 2, making it easier for staff to perform maintenance.

[0070] like Figure 11-12As shown, in one embodiment, the feeding mechanism 4 includes a receiving groove 42 for receiving cigarettes, an accelerating mechanism 43 for conveying cigarettes in the receiving groove 42 to a conveying pipe 41, and a support frame 44 for mounting the accelerating mechanism 43. The accelerating mechanism 43 includes an accelerating wheel 431 for conveying cigarettes and a second power member 432 for driving the accelerating wheel 431 to rotate. The accelerating wheel 431 is located below the receiving groove 42 and contacts the cigarettes and drives the cigarettes to move. An arc-shaped protective plate 49 is provided on the side of the support frame 44 away from the arc plate 77. This design, by setting up a receiving groove 42, allows the cigarette to enter the receiving groove 42 when it falls onto the arc plate 77. Under the action of the arc plate 77, the cigarette can enter the receiving groove 42. By setting up an acceleration wheel 431 and a second power component 432, the second power component 432 drives the acceleration wheel 431 to rotate. When the acceleration wheel 431 rotates, the cigarette moves forward and enters the conveying pipe 41, thereby achieving the purpose of conveying the cigarette to the conveying pipe 41, which facilitates the subsequent cutting of the cigarette.

[0071] like Figure 13 As shown, preferably, the acceleration wheel 431 includes two spaced-apart circular plates 433 and a connecting plate 434 evenly distributed between the two circular plates 433. The cigarette is placed on the connecting plate 434 between the two circular plates 433. This design, by setting two circular plates 433 and the internal connecting plate 434, facilitates the movement of the cigarette by the rotation of the circular plates 433 and the connecting plate 434, and also enables the positioning of the cigarette.

[0072] like Figure 12-13 As shown, in one embodiment, it further includes a first air hole 45 disposed on one side of the receiving groove 42 and an air block 46 disposed on the side of the acceleration wheel 431 away from the conveying pipe 41, which is provided with a second air hole 47. The first air hole 45 and the second air hole 47 are connected to an external fan. This design, by providing the first air hole 45 and the second air hole 47, can clean the acceleration wheel 431, avoiding the accumulation of tobacco shreds on the acceleration wheel 431 during the cigarette conveying process, thereby ensuring that the acceleration wheel 431 can stably convey the cigarette into the conveying pipe 41, ensuring the normal operation of the cigarette recycling process; secondly, by providing the air block 46, the air blowing direction of the second air hole 47 is the same as the cigarette's travel direction, and while the second air hole 47 is in action, it can blow the cigarette, assisting the cigarette to enter the conveying pipe 41.

[0073] like Figure 11As shown, in one embodiment, an adjustment mechanism 48 is further included for adjusting the position of the feeding mechanism 4. The adjustment mechanism 48 includes a mounting plate 481 disposed below the support frame 44, a guide rail 482 that slides with the mounting plate 481, and a third power component 483 for driving the mounting plate 481 to slide. This design, by providing the adjustment mechanism 48, allows for the adjustment of the position of the feeding mechanism 4 when a cigarette jam occurs during the feeding process of the feeding drum 32 and the adjustment mechanism 48. This releases the connection between the feeding mechanism 4 and the feeding drum 32, facilitates maintenance by staff, and effectively improves maintenance efficiency.

[0074] Preferably, the mounting plate 481 is provided with two spaced positioning plates 484, and the guide rail 482 is provided with two sensors 485 corresponding to the positioning plates 484. This design, by providing positioning plates 484 on the mounting plate 481 and configuring sensors 485 to cooperate with the positioning plates 484, facilitates the positioning of the feeding mechanism 4 after maintenance, ensuring accurate resetting of the feeding mechanism 4.

[0075] like Figure 14-15 As shown, in one embodiment, the screening device includes a screen 61 for receiving the outer shell of the cigarette and the tobacco inside after being cut by the cutting mechanism 5, a conveyor belt 62 disposed below the screen 61 for receiving the tobacco, and a vibration motor 63 for driving the screen 61 to vibrate. The screen 61 is provided with a first outlet 611, and the frame 1 is provided with a second outlet 621 on the side opposite to the first outlet 611 for the conveyor belt 62 to pass through. This design, by setting the screen 61 and the vibration motor 63, facilitates the screening of the outer shell of the cut cigarette and the tobacco inside, allowing the tobacco inside to fall into the conveyor belt 62 below. Furthermore, by placing the first outlet 611 and the second outlet 621 on both sides of the frame 1, it is convenient to collect the outer shell of the cigarette and the tobacco inside separately.

[0076] like Figure 14-15 As shown, in one embodiment, a mounting frame 64 for installing the screen 61 is also included, and a guide cylinder 65 is provided between the screen 61 and the conveyor belt 62. This design facilitates the installation of the screen 61 by providing the mounting frame 64, and guides the screened tobacco shreds by providing the guide cylinder 65, preventing the screened tobacco shreds from falling into the external environment.

[0077] Preferably, the guide cylinder 65 has a cylindrical structure that is wider at the top and narrower at the bottom, and the side plates of the guide cylinder 65 are inclined inward. This design can prevent the screened tobacco from falling into the external environment during the falling process, and can guide the screened tobacco to ensure that it falls onto the conveyor belt 62 below.

[0078] Preferably, the mounting frame 64 is provided with elastic elements 66, which are multiple springs evenly distributed and sleeved on the mounting frame 64, and the screen 61 is disposed on the multiple elastic elements 66. This design, by providing elastic elements 66, facilitates the vibration of the screen 61, thereby accelerating the screening of the cigarette casing and tobacco.

[0079] Preferably, the bottom of the lower frame 642 is provided with a shock-absorbing pad 641.

[0080] Preferably, the second power component 432, the third power component 483, and the fourth power component 543 include, but are not limited to, linear guide rail 482, cylinder, hydraulic cylinder, or electric push rod.

[0081] Preferably, the first power component 53 and the fifth power component 34 include, but are not limited to, an electric motor, a rotary cylinder, or a rotary cylinder.

[0082] Preferably, the frame 1 is equipped with an emergency stop button 11. This design allows the equipment to be quickly shut down when a problem occurs during operation.

[0083] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
