Referring to fig. 1, a cut tobacco recycling apparatus 100 according to a preferred embodiment of the present invention includes a cut tobacco separating mechanism 110, a material guiding mechanism 120, a guiding chute 130, and a screening mechanism 140.

The cut tobacco separating mechanism 110 is provided with a blowing station where the cut tobacco separating mechanism 110 separates cut tobacco from the tobacco pipe by blowing an air flow to the waste smoke 20. The separation of the cut tobacco by means of blowing avoids mechanical contact with the waste tobacco 20, thus maintaining the integrity of the cut tobacco better. The cigarette blowing station can be provided in plurality. Therefore, the tobacco separation mechanism 110 can simultaneously separate the tobacco from a plurality of waste cigarettes 20.

Referring to fig. 2, in the present embodiment, the tobacco shred separating mechanism 110 includes a tobacco feeding assembly 111, an air blowing assembly 113 and a tobacco pressing plate 115.

The smoke delivery assembly 111 may be intermittently moved to deliver the waste smoke 20 to the smoke blowing station. The smoke delivery assembly 111 may be in the form of rollers that cooperate with a conveyor on which the waste smoke 20 is carried for transport. Specifically, in the present embodiment, the surface of the smoke feeding assembly 111 is provided with a plurality of receiving grooves (not shown) perpendicular to the moving direction of the smoke feeding assembly 111, and the plurality of receiving grooves are distributed at intervals along the moving direction of the smoke feeding assembly 111. The waste smoke 20 can be accommodated in the accommodating groove during the transportation process. Therefore, the side wall can limit the waste smoke 20, prevent the waste smoke from rolling off the smoke conveying assembly 111, and avoid the waste smoke 20 on the smoke conveying assembly 111 from being disordered in sequence.

The blowing assembly 113 is arranged on the cigarette blowing station. Wherein, the blowing assembly 113 can blow out pure gas at high speed to generate gas flow. After the waste tobacco 20 enters the blowing station, the blowing assembly 113 can blow air toward the filter tip of the waste tobacco, thereby blowing the cut tobacco out of the tobacco pipe. For the case that a plurality of smoke blowing stations are arranged, the blowing assembly 113 can be correspondingly arranged in a plurality.

The cigarette pressing plate 115 is movably disposed. Specifically, the cigarette pressing plate 115 is disposed opposite to the surface of the cigarette feeding assembly 111, and the moving direction thereof is perpendicular to the surface of the cigarette feeding assembly 111. I.e. in the vertical direction as shown in fig. 1. Wherein the cigarette pressing plate 115 is operable to reciprocate in a direction perpendicular to the cigarette feeding assembly 111 to press or release the waste cigarette 20 at the cigarette blowing station. The part pressed by the cigarette pressing plate 115 is a filter part of the waste cigarette 20. When the waste smoke 20 is processed, the smoke pressing plate 115 moves toward the smoke sending unit 111, and the waste smoke is sandwiched between the smoke pressing plate 115 and the surface of the smoke sending unit 111. Therefore, when the blowing assembly 113 blows the waste smoke, the smoke pressing plate 115 can limit the waste smoke well to prevent the waste smoke from being blown away.

The cigarette pressing plate 115 may be driven by a separate driving member, or may share a driving member with the cigarette feeding assembly 111. The driving part can be a power element such as an air cylinder, an electric cylinder, a stepping motor and the like.

In order to better limit the waste smoke during the smoke pressing process, in the embodiment, the smoke pressing plate 115 is provided with a smoke pressing groove (not shown) on the side facing the smoke feeding assembly 111. The cross-sectional shape of the cigarette pressing groove can be arc, parabola, V-shaped or U-shaped. When the cigarette pressing plate 115 presses the waste cigarette, the waste cigarette can be located in the cigarette pressing groove. At this time, the contact area of the cigarette pressing plate 115 and the waste cigarette 20 is increased by the inner wall of the cigarette pressing groove, so that the waste cigarette 20 can be prevented from being crushed. Meanwhile, the cigarette pressing groove can be matched with the accommodating groove in the cigarette conveying assembly 111, so that the waste cigarette 20 is better limited.

In addition, in order to further enhance the effect of the cigarette pressing, an elastic layer (not shown) is disposed on the cigarette pressing plate 115 facing the cigarette feeding assembly 111, and the cigarette pressing groove is opened on the elastic layer. The elastic layer can be formed by elastic materials such as rubber, silica gel, foam and the like.

The resilient layer allows the compacting plate 115 to be in flexible contact with the waste smoke when compacting the waste smoke. Therefore, the pressing stroke of the cigarette pressing plate 115 can be properly increased to enable the elastic layer to be extruded and deformed, so that the filter tip of the waste cigarette is elastically pressed, and the cut tobacco cannot be blown out due to excessive pressing.

In this embodiment, the tobacco shred separating mechanism 110 further comprises a cigarette jumping prevention assembly 117 arranged on the cigarette blowing station. The anti-smoke-jump assembly 117 includes a fixedly disposed elastic support 1172 and a pressure rod 1174 mounted on the elastic support 1172. Wherein, the pressure rod 1174 extends along the moving direction of the cigarette feeding component 111 and is opposite to the surface of the cigarette feeding component 111 and arranged at intervals.

Specifically, the elastic support 1172 may be an elastic metal plate, one end of which is fixedly disposed, and the other end of which is a free end and extends to the surface of the smoke feeding assembly 111, and the pressing rod 1174 is disposed on the free end. The resilient support 1172 is resiliently deformable when subjected to an external force to absorb the impact. The distance between the pressure rod 1174 and the surface of the smoke feeding component 111 is slightly larger than the diameter of the waste smoke.

Therefore, in the process that the waste cigarette is driven by the cigarette feeding component 111 to do intermittent motion, the pressure rod 1174 can block the cigarette when the cigarette jumps, so that the waste cigarette can be prevented from jumping to be separated from the cigarette feeding component 111 and finally causing messy cigarettes. Moreover, when the cigarette pressing plate 115 and the waste cigarette are bonded to bring the waste cigarette, the pressing rod 1174 can prevent the waste cigarette from moving upwards, so that the messy cigarette is further avoided. In addition, the cigarette jump prevention assembly 117 does not affect the normal movement of the cigarette feeding assembly 111 because of the specific distance between the press rod 1174 and the cigarette feeding assembly 111.

Further, in this embodiment, there are two pressure rods 1174, and the two pressure rods 1174 are parallel to each other and spaced apart from each other. Wherein, two depression bars 1174 can provide more balanced effort to the useless cigarette of jumping, press the cigarette effect more balanced promptly to the effect of preventing the messy cigarette is better. Moreover, the distance between the two pressing rods 1174 is larger than the size of the cigarette pressing plate 115, so that the cigarette jumping prevention assembly 117 can give way to the cigarette pressing plate 115, so that the cigarette pressing plate 115 can normally perform cigarette pressing operation.

The material guiding mechanism 120 includes a material guiding cavity 121 and a spiral feeding assembly 123. The spiral feeding assembly 123 is rotatably installed in the material guiding cavity 121, and a feeding hole 1121 and a discharging hole 1122 are formed in a side wall of the material guiding cavity 121. The screw feeding assembly 123 can generate a driving force in a specific direction through rotation, so as to drive the material in the material guiding cavity 121 to be fed in the specific direction. Specifically, the feeding direction of the screw feeding assembly 123 is directed from the feeding hole 1121 to the discharging hole 1122.

The material guiding cavity 121 may be formed by metal, and has a generally strip-shaped structure, and the material inlet 1121 and the material outlet 1122 are respectively located at two ends of the material guiding cavity 121. The screw feeding member 123 may be a rotating shaft having a spiral groove on a surface thereof, or may be composed of a rotating shaft and a blade provided on the rotating shaft.

The material guide cavity 121 is communicated with the discharge end of the cut tobacco separating mechanism 110 through the guide groove 130. The guide groove 130 is a hollow cavity structure with two open ends. The guide groove 130 has an opening at one end thereof on the side of the blowing station and opposite to the air flow direction, and an opening at the other end thereof communicating with the feed port 1211.

As shown in fig. 2, the air blowing assembly 113 is disposed at the right side of the smoke blowing station and blows air from right to left. At this time, the opening at one end of the guide slot 130 is located at the left side of the smoke blowing station and is arranged towards the right. After the cut tobacco is separated from the paper tube under the action of the air blowing assembly 113, stronger air flow still exists at the tobacco blowing station. Therefore, the blown tobacco shreds can directly enter the guide groove 130 under the action of the air flow, so that the tobacco shreds are prevented from splashing under the action of the air flow.

The guide groove 130 may be formed by splicing or winding a metal plate. Further, the guide groove 130 extends generally in a curved line, and has a smooth inner wall to prevent the cut tobacco from being caught therein. The end of the guide groove 130 may be connected to the edge of the feed port 1211 by welding, screwing, or the like. The cut tobacco entering the guide groove 130 may move toward the feed opening 1211 under the gravity and finally fall into the material guide cavity 121. When the tobacco shred recycling device 100 is arranged on a horizontal plane, the material guide cavity 121 is positioned below the tobacco blowing station.

In the present embodiment, the inner diameter of the guide groove 130 gradually decreases in the extending direction from the end of the guide groove 130 close to the feed opening 1121 to the end away from the feed opening 1121.

In general, the guide groove 130 is "thicker" at a portion closer to the feed opening 1121 and "thinner" at a portion closer to the blowing station. In this way, the guide groove 130 is generally in an inverted funnel shape, and the cut tobacco enters from the end with the smaller opening and moves to the end with the larger opening, so that the cut tobacco can be effectively prevented from forming a blockage in the guide groove 130.

The feed end of the screening mechanism 140 is in communication with a discharge 1122. That is, the cut tobacco conveyed by the material guiding mechanism 120 may finally enter the screening mechanism 140 through the discharge port 1122. The screening mechanism 140 is used for screening the cut tobacco, so that impurities mixed in the cut tobacco are removed, and pure cut tobacco is obtained. In this embodiment, the screening mechanism 140 is a multi-layer vibrating screen. The multilayer vibrating screen can carry out flexible screening to the pipe tobacco. Moreover, the tobacco shreds are less damaged by screening through vibration compared with other modes. Therefore, the integrity of the cut tobacco can be further ensured.

When the cut tobacco is recovered, the cut tobacco in the waste tobacco 20 is separated at the tobacco blowing station and enters the material guide cavity 121 through the guide groove 130; the spiral feeding assembly 123 works to drive the cut tobacco entering the material guiding cavity 121 from the inlet 1211 to the outlet 1212, and finally the cut tobacco enters the screening mechanism 140 from the outlet 1212 to realize screening. The guide groove 130 and the material guide cavity 121 can provide a relatively closed environment for the tobacco shred conveying process. Moreover, the cut tobacco is conveyed in the material guide cavity 121 in a spiral feeding mode, and dust cannot fly. Therefore, the dust generated in the tobacco shred recovery process can be effectively avoided.

In the present embodiment, the screw feeding assembly 123 includes a rotating shaft 1231 and a flexible blade 1232 disposed on the rotating shaft 1231.

In particular, the flexible blades 1232 may be molded from plastic, rubber, etc. Therefore, in the process of driving the cut tobacco to feed, the flexible blades 1232 can effectively avoid damaging the cut tobacco, so that the integrity of the cut tobacco is further ensured.

Referring to fig. 1, in the present embodiment, the cut tobacco recycling apparatus 100 further includes a conveying mechanism 150, the conveying mechanism 150 includes a conveyor belt 151 extending from a discharge port 1212 to a feeding end of the screening mechanism 140, and the discharge port 1212 faces a surface of the conveyor belt 151.

The conveyor belt 151 may be sleeved on a plurality of driving wheels to realize conveying. The cut tobacco is discharged from the discharge port 1212, falls onto the conveyor belt 151, and is lifted by the conveyor belt 151 into the screening mechanism 140. Because the screening mechanism 140 is higher in height, the tobacco shreds are lifted by the conveyor belt 151, and the tobacco shred separating mechanism 110 and the material guiding mechanism 120 can be conveniently arranged.

Further, in this embodiment, the conveying mechanism 150 further includes a housing 153 covering the surface of the conveying belt 151, and the housing 153 is provided with a through hole (not shown) communicating with the discharge port 1122.

The housing 153 may be formed of metal and may completely surround or partially surround the conveyor belt 151. As shown in fig. 1, the cover 153 covers the upper surface of the conveyor belt 151. The discharge port 1122 is conveniently connected to the edge of the through hole by welding, screwing, or the like. In this way, the cut tobacco is less likely to leak when transferred from the discharge port 1122 to the conveyor belt 151. Moreover, the area of the conveyor belt 151 for conveying the cut tobacco may be closed by the cover 153, so that the cut tobacco may be prevented from scattering during the lifting.

In this embodiment, the tobacco shred recycling device 100 further includes a receiving mechanism 160, and the receiving mechanism 160 is provided with a plurality of bearing discs 161. The carrying tray 161 is used for carrying the packing box 30, and the packing box 30 is used for collecting the recovered pure cut tobacco. The receiving mechanism 160 can perform an intermittent circular motion, so that the plurality of carrying trays 161 are aligned with the discharging end of the screening mechanism 140 in sequence.

When one of the trays 161 is aligned with the discharge end of the screening mechanism 140, the shredded tobacco discharged from the discharge end of the screening mechanism 140 falls into the packing box 30 on that tray 161. By controlling the interval time of the intermittent movement of the receiving mechanism 160, the next packing box 30 immediately moves to the lower part of the discharge end of the screening mechanism 140 along with the bearing plate 161 after the previous packing box 30 is filled. The receiving mechanism 160 is sequentially circulated, so that the packing boxes 30 on the plurality of bearing plates 161 can be sequentially filled, and workers only need to take down the filled packing boxes 30 and put on new packing boxes 30.

Specifically, the receiving mechanism 160 may be a structure in which a plurality of carrier trays 161 are disposed around the rotating shaft. The rotation shaft can drive the plurality of bearing discs 161 to rotate, thereby realizing intermittent circular motion.

Further, in the present embodiment, the material receiving mechanism 160 further includes a weighing member 163 disposed on the carrying tray 161.

Specifically, the weighing member 163 may be an electronic scale. When one of the carrier trays 161 is moved into alignment with the discharge end of the screening mechanism 140, the weighing member 163 may display the weight thereon in real time. By observing the weight reading, it can be determined whether the corresponding packing box 30 is full.

In the tobacco shred recycling device 100, the tobacco shreds in the waste tobacco 20 are separated at the tobacco blowing station and enter the guide groove 130 under the action of the air flow. The cut tobacco can enter the material guiding cavity 121 from the guide groove 130 under the action of gravity, the spiral feeding assembly 123 drives the cut tobacco entering the material guiding cavity 121 from the feeding port 1211 to the discharging port 1212, and finally the cut tobacco enters the screening mechanism 140 from the discharging port 1212 to realize screening. The guide groove 130 and the material guiding cavity 121 are both relatively closed structures, so that dust leakage can be effectively avoided. Moreover, the cut tobacco is conveyed in the material guide cavity 121 in a spiral feeding mode, so that dust can be effectively prevented from flying. It can be seen that the above tobacco shred recycling device 100 can effectively prevent dust from flying.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
