Description

Technical Field

[0001] This application relates to the field of cigarette production machinery and equipment technology, specifically to cigarette recycling equipment. Background Technology

[0002] In the cigarette production process, a certain number of defective cigarettes are often generated. To achieve green production and reduce production costs, it is necessary to classify and recycle the tobacco, filters, and cigarette paper from these defective cigarettes. Especially important is the recycling of the more expensive tobacco, which requires ensuring high purity. The cigarette breaking and recycling process typically involves separating the tobacco using steam rehydration and mechanical cutting. However, directly breaking and recycling cigarettes with flavoring capsules or powdered flavorings in the filters would cause these capsules or powdered flavorings to mix into the tobacco, affecting the purity of the tobacco, the processing stability of the cigarette, and its combustion stability. Therefore, currently, when recycling cigarettes with flavorings in the filters, the cigarette filters must first be removed before the breaking and recycling process can begin. Currently, most filter removal is done manually, which is inefficient, labor-intensive, and results in significant tobacco breakage. Summary of the Invention

[0003] To at least partially solve the above problems, embodiments of this application provide a cigarette recycling device for recycling cigarettes with filters. The cigarette recycling device includes a cigarette sorting and arranging mechanism, a cigarette filter separation mechanism, and a cigarette paper and tobacco separation mechanism. The cigarette sorting and arranging mechanism includes a vibrating trough and a conveyor belt. The cigarette sorting and arranging mechanism receives cigarettes to be recycled through the vibrating trough and arranges the cigarettes onto the conveyor belt. The cigarette filter separation mechanism includes a first cigarette taking component, a drum assembly, and a shearing component. The first cigarette taking component is used to take cigarettes off the conveyor belt and convey them to the drum assembly. The drum assembly is configured to drive the movement of the cigarettes. The drum assembly and the shearing component are spaced apart to form a [missing information - likely a device or mechanism]. In the gap of the cigarette filter being cut, when the drum drives the cigarette through the gap used to cut the cigarette filter, the cigarette can be cut into a filter part and a filterless cigarette. The drum assembly is also configured to adjust the position of the cigarette on the drum assembly based on the positional relationship between the cigarette filter and the cutting element, so that the filters of cigarettes in different postures on the drum assembly can be cut by the cutting element. The cigarette paper and tobacco separation mechanism includes a second cigarette taking assembly, a cigarette guide rail, a cutter, and a paper suction wheel. The second cigarette taking assembly is used to take the filterless cigarette from the drum assembly onto the cigarette guide rail. The cutter is used to axially cut the cigarette paper of the filterless cigarette on the cigarette guide rail. The paper suction wheel is used to absorb the cut cigarette paper.

[0004] In some embodiments, the vibrating trough includes a vibrating trough frame, a trough body, and a vibrating motor. The trough body is mounted on the vibrating trough frame, and the trough body and the vibrating trough frame are connected by multiple damping plates with the same inclination direction. The damping plates are used to limit the vibration of the trough body within a predetermined dimension. The vibrating motor is mounted on the trough body and is used to drive the trough body to vibrate. The trough body is provided with a material discharge platform, a primary sorting mechanism, and a secondary sorting mechanism. The heights of the material discharge platform, the primary sorting mechanism, and the secondary sorting mechanism decrease sequentially. The material discharge platform is used to receive cigarettes to be recycled. The primary sorting mechanism includes multiple first partitions, and a through groove with a width greater than the diameter of the cigarette is formed between two adjacent first partitions. The secondary sorting mechanism is located below the primary sorting mechanism to receive cigarettes falling from the through groove. The secondary sorting mechanism has multiple V-shaped grooves. The opening size of the V-shaped grooves is greater than the diameter of the cigarette, and the extension direction of the V-shaped grooves is the same as the extension direction of the through groove.

[0005] In some embodiments, one end of the trough is provided with an upper accelerating roller and a lower accelerating roller that are parallel and spaced apart. The upper accelerating roller and the lower accelerating roller can rotate in opposite directions under the drive of an acceleration motor. The lower accelerating roller has an arc groove corresponding to the V-shaped groove. When the cigarette passes through the gap between the upper accelerating roller and the lower accelerating roller, it can contact the upper accelerating roller and the lower accelerating roller simultaneously to throw the cigarette horizontally away from the trough. A conveyor belt is provided at the outlet of the gap between the upper accelerating roller and the lower accelerating roller to receive the cigarette that is thrown horizontally.

[0006] In some embodiments, the conveyor belt is provided with a plurality of second partitions along its circumference, which divide the circumference of the conveyor belt into a plurality of transport compartments distributed along the circumference of the conveyor belt. The distance between two adjacent second partitions and the width of the second partitions are less than the length of the cigarette. A deceleration brush is provided on the side of the conveyor belt away from the trough, and the cigarettes thrown horizontally can impact the deceleration brush.

The negative pressure drum is at least partially disposed in the hopper. Multiple smoke slots extending axially along the negative pressure drum are formed on the drum in the circumferential direction, and negative pressure holes are formed in the smoke slots. The air valve communicates with the negative pressure holes and is connected to a negative pressure source. The servo motor is driven by the negative pressure drum and is used to drive the negative pressure drum to rotate. The reversing roller is disposed on the path of the cigarette moving from the hopper to the shearing piece. A gap is formed between the reversing roller and the negative pressure drum, allowing a single cigarette in the smoke slot to pass through. The rotation direction of the reversing roller is the same as the rotation direction of the negative pressure drum.

The number of shearing elements is two, which are disposed on both sides of the negative pressure drum and located around the negative pressure drum. The two shearing components are symmetrically arranged at the same position and about the center of the negative pressure drum axis. The two shearing components correspond to the filter positions of the cigarettes in the first and second slots, respectively. The color mark sensor is configured to identify the filter end and the lit end of the cigarette. The first blowing assembly is connected to the color mark sensor and is in communication with external high-pressure gas. The gas outlet of the first blowing assembly faces the cigarette slot. The first blowing assembly controls its working state based on the detection result of the color mark sensor so as to blow the cigarettes in the first slot whose filter does not correspond to the shearing component of the first slot to the second slot.

[0031] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a cigarette recycling device for recycling cigarettes with filters. The cigarette recycling device includes a cigarette sorting and arranging mechanism 100, a cigarette filter separation mechanism 200, and a cigarette paper and tobacco separation mechanism 300.

[0032] The cigarette sorting and arranging mechanism 100 includes a vibrating groove and a conveyor belt 114. The mechanism receives cigarettes to be recycled through the vibrating groove and arranges them onto the conveyor belt 114. The cigarette filter separation mechanism 200 includes a first cigarette-taking assembly, a drum assembly, and a shearing component. The first cigarette-taking assembly removes cigarettes from the conveyor belt 114 and conveys them to the drum assembly. The drum assembly is configured to drive the cigarettes. The drum assembly and the shearing component are spaced apart to form a gap for shearing the cigarette filter. When the drum drives the cigarette through the gap, the cigarette can be sheared into a filter portion and a non-filter portion. The filterless cigarette has a drum assembly that is also configured to adjust the position of the cigarette on the drum assembly based on the positional relationship between the cigarette's filter and the shearing member, so that the filters of cigarettes in different postures on the drum assembly can be cut by the shearing member; the cigarette paper and tobacco separation mechanism 300 includes a second cigarette taking component 302, a cigarette guide rail 304, a cutter 308, and a paper suction wheel 311. The second cigarette taking component 302 is used to take the filterless cigarette from the drum assembly onto the cigarette guide rail 304, the cutter 308 is used to axially cut the cigarette paper of the filterless cigarette on the cigarette guide rail 304, and the paper suction wheel 311 is used to absorb the cut cigarette paper.

[0033] The cigarette recycling equipment provided in the embodiments of this application, through the processing of the cigarette sorting and arranging mechanism 100, the cigarette filter separation mechanism 200, and the cigarette paper and tobacco separation mechanism 300, can sort out disordered cigarettes and separate the cigarette filter and tobacco. It includes the entire process of cigarette recycling, has high operating efficiency, effectively prevents impurities such as flavor capsules and powdered flavorings in the filter from mixing into the tobacco, and can recycle cigarettes without pre-treatment, resulting in low labor intensity.

[0034] like Figure 3As shown, in some embodiments, the vibrating groove includes a vibrating groove frame 104, a groove body 101, and a vibration motor 103. The groove body 101 is mounted on the vibrating groove frame 104, and the groove body 101 and the vibrating groove frame 104 are connected by a plurality of damping plates 102 with the same inclination direction. The damping plates 102 are used to limit the vibration of the groove body 101 within a predetermined dimension to ensure that the cigarette moves in a predetermined direction. One end of the damping plate is connected to the lower part of the groove body 101, and the other end is connected to the vibrating groove frame 104. The groove body 101 can vibrate relative to the vibrating groove frame 104. The vibration motor 103 is mounted on the groove body 101 and is used to drive the groove body 101 to vibrate. The vibration motor 103 can be fixedly connected to the lower middle section of the groove body 101. The trough 101 includes a material discharge platform 1011, a primary sorting mechanism 1012, and a secondary sorting mechanism 1013. The heights of the material discharge platform 1011, the primary sorting mechanism 1012, and the secondary sorting mechanism 1013 decrease sequentially. The material discharge platform 1011 receives cigarettes to be recycled. The primary sorting mechanism 1012 includes multiple first partitions, with a through groove wider than the cigarette diameter formed between adjacent first partitions. The secondary sorting mechanism 1013 is positioned below the primary sorting mechanism 1012 to receive cigarettes falling from the through groove. The secondary sorting mechanism 1013 has multiple V-shaped grooves, the openings of which are larger than the cigarette diameter, and the extension direction of the V-shaped grooves is the same as the extension direction of the through groove. Preferably, the opening size of the V-shaped grooves can be slightly larger than the cigarette diameter.

[0035] In some embodiments, one end of the trough 101 is provided with an upper accelerating roller 105 and a lower accelerating roller 106 arranged parallel and spaced apart. The upper accelerating roller 105 and the lower accelerating roller 106 can be fixed to a first accelerating bracket 107 and a second accelerating bracket 108 respectively by bearings. The first accelerating bracket 107 and the second accelerating bracket 108 are fixed to the vibrating trough frame 104. An accelerating motor 109 is provided on the first accelerating bracket 107, and the power of the accelerating motor 109 is transmitted to the upper accelerating roller 105 and the lower accelerating roller 106 through an accelerating synchronous belt 110. The lower accelerating roller 106, the upper accelerating roller 105, and the lower accelerating roller 106 can rotate in opposite directions under the drive of the accelerating motor 109. The lower accelerating roller 106 has an arc groove corresponding to the V-shaped groove. When the cigarette passes through the gap between the upper accelerating roller 105 and the lower accelerating roller 106, it can contact the upper accelerating roller 105 and the lower accelerating roller 106 at the same time, so as to throw the cigarette horizontally away from the groove 101. The conveyor belt 114 is set at the outlet of the gap between the upper accelerating roller 105 and the lower accelerating roller 106 to receive the cigarette that is thrown horizontally.

[0036] In some embodiments, the conveyor belt 114 is provided with a plurality of second partitions along its circumference. The plurality of second partitions divide the circumference of the conveyor belt 114 into a plurality of transport compartments distributed along the circumference of the conveyor belt 114. The spacing between two adjacent second partitions and the width of the second partitions are less than the length of the cigarettes, so as to initially control the posture of the cigarettes, which is conducive to the neat arrangement of the cigarettes. At the same time, it allows both ends of the cigarettes to extend out of the second partitions, which is convenient for further posture correction and cigarette picking in subsequent processes. A deceleration brush 111 is provided on the side of the conveyor belt 114 away from the trough 101. The cigarettes thrown horizontally can impact the deceleration brush 111, which can decelerate the cigarettes and reduce the damage caused by the impact. Two correction baffles 113 are respectively provided on both sides of the conveyor belt 114. The distance between the two correction baffles 113 gradually narrows along the conveying direction of the conveyor belt 114. In this way, when the cigarettes move with the conveyor belt 114, they can be gradually corrected to a posture perpendicular to the movement direction of the conveyor belt 114, so as to achieve neat arrangement of the cigarettes. Preferably, the distance between the two correction baffles 113 can be gradually narrowed to be slightly larger than the length of the cigarette. The conveyor belt 114 can be mounted on the trough 101 via the conveyor belt frame 115. For example, the conveyor belt frame 115 is fixed on the trough 101. The conveyor belt frame 115 is equipped with the conveyor belt 114 and the conveyor belt motor 116. The synchronous conveyor belt 117 transmits power from the conveyor belt motor 116 to the conveyor belt 114. A brush bracket 112 is provided on one side of the conveyor belt frame 115, and a deceleration brush 111 is provided on the brush bracket 112.

[0037] In some embodiments, the first cigarette-collecting assembly includes a cigarette-collecting plate 203, a cigarette inlet baffle 204, and a hopper 205. Two shovels are formed at the ends of the cigarette-collecting plate 203, forming a concave shape with the body of the cigarette-collecting plate 203. The two shovels are positioned close to the conveyor belt 114 and are located on opposite sides of the second partition. This structure allows the cigarette-collecting plate 203 to scoop up cigarettes from the conveyor belt 114, with both ends of the cigarette resting on the two shovels. The cigarette inlet baffle 204 and the cigarette-collecting... Plates 203 are spaced apart, and the smoke inlet baffle 204 extends downward to the top of the second partition and can contact the second partition to prevent the cigarette from moving backward. The smoke picker plate 203, the smoke inlet baffle 204, and the second partition in contact with the smoke inlet baffle 204 form a cigarette channel. The smoke picker plate 203 extends into the hopper 205 and is inclined downward in the hopper 205. When the conveyor belt 114 is running, the cigarette is pushed by the second partition and enters the hopper 205 through the cigarette channel. The smoke picker plate 203 can be fixed on the hopper 205. As the conveyor belt 114 runs, the cigarette is continuously scooped up by the smoke picker plate 203 and gradually accumulates in the cigarette channel. Subsequent cigarettes will always push forward and move the cigarette upward along the smoke picker plate 203. When the cigarette moves to the part of the smoke picker plate 203 located in the hopper 205, it rolls into the hopper 205 under the action of gravity.

[0038] In some embodiments, the drum assembly includes a negative pressure drum 208, an air valve 214, a servo motor 213, and a reversing roller 215. The negative pressure drum 208 is at least partially disposed in the hopper 205. A plurality of smoke grooves extending axially along the negative pressure drum 208 are formed on the drum along the circumference, and negative pressure holes are formed in the smoke grooves. The air valve 214 communicates with the negative pressure holes and is connected to a negative pressure source. The servo motor 213 is drivenly connected to the negative pressure drum 208 and is used to drive the negative pressure drum 208 to rotate. The reversing roller 215 is disposed on the path of the cigarette moving from the hopper 205 to the shearing piece. A gap is formed between the reversing roller 215 and the negative pressure drum 208, allowing a single cigarette in the smoke groove to pass through. The rotation direction of the reversing roller 215 is the same as the rotation direction of the negative pressure drum 208. The negative pressure drum 208 can be fixedly connected to the drive shaft 209. The two ends of the drive shaft 209 are rotatably connected to the vertical bearing seat 210 and the horizontal bearing seat 211, respectively. The coupling 212 fixes the drive shaft 209 and the servo motor 213. The opening side of the air valve 214 is in contact with one side of the negative pressure drum 208. The backward roller 215 can be installed on the backward roller bearing seat 216 and rotated under the drive of the backward roller motor 217. The backward roller 215, the backward roller bearing seat 216 and the backward roller motor 217 can be located at the upper left part of the circumference of the negative pressure drum 208.

[0039] In some embodiments, the drum assembly further includes an outer guide plate 220 and an inner guide plate 219, a color mark sensor 221, and a first blowing assembly 223. The outer guide plate 220 and the inner guide plate 219 are respectively disposed on both sides of the negative pressure drum 208. Each tobacco trough includes a first trough segment and a second trough segment, both of which can accommodate a whole cigarette. The first trough segment is located inside the hopper 205, and the second trough segment is at least partially located outside the hopper 205, so that when the cigarette in the hopper 205 is adsorbed by the negative pressure drum 208, it can only enter the first trough segment. There are two shearing members, which are disposed on both sides of the negative pressure drum 208 and located on the negative pressure drum 208. Two shearing elements are symmetrically positioned at the same circumferential position of the pressure drum 208 and about the axial center of the negative pressure drum 208, respectively, with the two shearing elements corresponding to the filter positions of the cigarettes in the first and second slots. A color mark sensor 221 is configured to identify the filter end and the lit end of the cigarette. A first air-blowing assembly 223 is connected to the color mark sensor 221 and communicates with external high-pressure gas. The gas outlet of the first air-blowing assembly 223 faces the cigarette slot. The first air-blowing assembly 223 controls its operating state based on the detection result of the color mark sensor 221 to blow cigarettes in the first slot whose filters do not correspond to the shearing elements in the first slot towards the second slot. The first air-blowing assembly 223 can change its operating state by opening and closing a solenoid valve; when air blowing is detected, the solenoid valve opens.

[0040] In some embodiments, the drum assembly further includes a main frame 201, a wall plate 202, an arc plate 218, and an arc pressure plate 225. A support plate is provided on the main frame 201. The wall plate 202 is disposed on the main frame 201 and is perpendicular to the support plate. The negative pressure drum 208 and the servo motor 213 are respectively disposed on both sides of the wall plate 202. The hopper 205 is disposed on the same side of the wall plate 202 as the negative pressure drum 208. The hopper 205 can be fixed to the wall plate 202 at a certain distance by studs. The arc plate 218 is concentrically and spaced apart from the negative pressure drum 208. The outer guide plate 220 and the inner guide plate 219 are respectively disposed on both sides of the arc plate 218. The arc pressure plate 225 is disposed on the shearing member and is used to press down the filter part of the cigarette. The solenoid valves in the arc-shaped plate 218, inner guide plate 219, outer guide plate 220, color mark sensor 221, and first air blowing assembly 223 can be fixed as a whole and located on the upper right side of the circumference of the negative pressure drum 208. The shear block 224 and arc-shaped pressure plate 225 can be fixed as a whole and located on the right side of the circumference of the negative pressure drum 208. A protective cover 206 can also be provided on the main frame 201 to protect part of the structure of the cigarette filter separation mechanism 200. The smoke inlet baffle 204 can be set on the upper part of the smoke take-up plate 203 and fixedly connected to the protective cover 206. A protective door 207 can be provided on the protective cover 206 and is hinged to the protective cover 206.

[0041] In some embodiments, the second cigarette taking assembly 302 includes a shovel tooth and a cigarette taking baffle. The shovel tooth and the cigarette taking baffle are spaced apart, and the shovel tooth and the cigarette taking baffle bracket form a channel for the mouthless cigarette to pass through. The shovel tooth contacts the negative pressure drum 208, and the end of the cigarette taking baffle is spaced apart from the negative pressure drum 208.

The cigarette without a mouthpiece is connected to the transmission of the machine 315. When the cigarette without a mouthpiece on the cigarette guide rail 304 passes through the pressure roller 305, the pressure roller 305 can apply pressure to the cigarette without a mouthpiece. The positive and negative pressure air valves 312 are coaxially arranged with the paper suction roller 311. Multiple through holes are formed on the surface of the paper suction roller 311. The positive and negative pressure air valves 312 communicate with the through holes. The positive and negative pressure air valves 312 are set to apply positive and negative pressure to the through holes based on the position of the cigarette paper on the paper suction roller 311. The tobacco baffle 316 is arranged on the side of the paper suction roller 311 away from the cutter 308. The cigarette taking mechanism, cigarette guide rail 304, positive and negative pressure air valves 312, tobacco baffle 316, and drive motor 315 can all be mounted on the support plate 301. Two bearing seats 319 can also be mounted on the support plate 301. The second cigarette taking assembly 302 is located at the lower right of the negative pressure drum 208. One end of the second cigarette taking assembly 302 is equipped with a second air blowing assembly 303, and the other end is the cigarette guide rail 304. The pressure roller 305, the first drive shaft 306, and the first pulley 307 are fixed together in the bearing seat and located above the cigarette guide rail 304. The cutter 308, the first... The second drive shaft 309 and the second pulley 310 are fixed together and placed in a bearing housing, located below the cigarette guide rail 304.

The paper suction wheel 311, the third drive shaft 313, and the third pulley 314 are fixed together and placed on a bearing inside the positive and negative pressure valve 312. The tobacco baffle 316 is located below the paper suction wheel 311. A cigarette paper conveying pipe 317 is provided next to the paper suction wheel 311. The round belt 318 transmits the power of the drive motor 315 to the first pulley 307, the second pulley 310, and the third pulley 314. The cigarette recycling equipment may also include a filter cigarette paper collection bin 226 and a tobacco collection bin 227, which are placed below the main frame 201.

[0043] The working principle of the cigarette recycling device provided in the embodiments of this application is as follows:

[0044] The trough 101 generates high-frequency vibration under the action of the vibrating motor 103. The damping plate 102 can isolate the vibration from the vibrating trough frame 104. At the same time, the inclined vibrating plate can ensure that the cigarettes jump forward in the trough 101. The disordered defective cigarettes are transported by the elevator to the material dropping platform 1011 of the trough 101. Under the action of vibration, the cigarettes will be evenly dispersed on the material dropping platform 1011 and fall to the first-level sorting mechanism 1012 in a forward jumping manner. The longitudinally arranged cigarettes fall into the lower second-level sorting mechanism 1013 along the through groove formed by several first partitions. The transverse or diagonal cigarettes continue to jump in the first-level sorting mechanism 1012. Finally, the cigarettes become longitudinal and fall into the lower second-level sorting mechanism 1013. Since the V-shaped groove of the second-level sorting mechanism 1013 is slightly larger than the cigarettes, each cigarette continues to move forward in the V-shaped groove under the action of vibration, forming a longitudinal cigarette stream.

[0045] The acceleration motor 109 drives the upper acceleration roller 105 and the lower acceleration roller 106 to rotate in opposite directions. The lower acceleration roller 106 has an arc groove corresponding to the V-shaped groove of the secondary sorting mechanism 1013. One end of the cigarette leaves the secondary sorting mechanism 1013 and enters the upper acceleration roller 105 and the lower acceleration roller 106, and is appropriately compressed, so that the cigarette moves at high speed along the tangent of the movement of the two acceleration rollers. This ensures that the cigarette has a high speed when it leaves the groove 101, so as to ensure that the cigarette has a stable projectile motion before entering the conveyor belt 114, and that the cigarette is still arranged in a regular longitudinal pattern when it enters the conveyor belt 114. At the same time, it can prevent the cigarette from piling up on the secondary sorting mechanism 1013 and causing the cigarette arrangement to become disordered.

[0046] After the cigarette accelerates, it collides with the deceleration brush 111. The brush decelerates the cigarette and it immediately falls onto the conveyor belt 114 below. The conveyor belt 114 is equipped with several second partitions, which divide the circumferential space of the conveyor belt 114 into multiple transport compartments. The cigarette falls into the transport compartments, which can ensure that the cigarette does not become disordered when it falls into the conveyor belt 114 and during the transport process. The conveyor belt motor 116 drives the conveyor belt 114 and carries the cigarette to the cigarette filter separation mechanism 200. The straightening baffles 113 on both sides of the conveyor belt 114 gradually narrow along the cigarette transport direction to a width slightly wider than the length of the cigarette. The wider part makes it easier for the cigarette to fall onto the conveyor belt 114, and the gradual narrowing can align the cigarettes, ultimately forming a neat horizontal cigarette stream.

[0047] Two shovels at one end of the smoke-receiving plate 203 remove the cigarette from the conveyor belt 114 and move along the smoke-receiving plate 203. The right end of the smoke inlet baffle 204 contacts the second partition on the conveyor belt 114 to prevent the cigarette from moving backward. The smoke-receiving plate 203, the smoke inlet baffle 204 and the second partition of the conveyor belt 114 form a cigarette channel. Since the second partition of the conveyor belt 114 always moves forward, subsequent cigarettes will always push forward and move along the smoke-receiving plate 203 into the hopper 205.

[0048] After the cigarettes enter the hopper 205, they are stored at a certain height. The negative pressure drum 208 has several cigarette slots, each with a negative pressure hole. These holes are connected to an air valve 214, which is connected to an external negative pressure source. This creates negative pressure within the cigarette slots of the negative pressure drum 208. A servo motor 213 drives the negative pressure drum 208 to rotate. The cigarettes in the hopper 205, under the influence of gravity and negative pressure, enter the first section of the cigarette slots on the negative pressure drum 208. The cigarettes move with the negative pressure drum 208, and a reverse roller motor 217 drives them to move backward. Roller 215 rotates in the same direction as the negative pressure drum 208. The reversing roller 215 can make slight contact with the cigarette in the tobacco trough, ensuring that there is only one cigarette in each tobacco trough of the negative pressure drum 208. The cigarette passes through the color mark sensor 221 to identify the filter end and the lit end of the cigarette by color. When the cigarette is at the filter end, the solenoid valve of the first blowing assembly 223 does not open, and the cigarette continues to move along the outer guide plate 220. When it is identified as the lit end, the solenoid valve opens, and high-pressure air is introduced to blow the cigarette into the second section of the tobacco trough and abut against the inner guide plate 219. The cigarette stick continues to move along the inner guide plate 219, eventually shearing the filter ends of all cigarette sticks onto both sides of the negative pressure drum 208. The arc plate 218 prevents the blown cigarette stick from deviating from the cigarette groove. After passing through the arc plate 218, the cigarette stick is pressed into the cigarette groove of the negative pressure drum 208 by the arc pressure plate 225 and continues to move. There is a shearing block 224 on each side of the negative pressure drum 208. The end face of the negative pressure drum 208 and the shearing block 224 form a shearing force to separate the cigarette filter. The separated filter tip falls into the filter cigarette paper collection bin 226 provided below. The cigarette stick without a filter tip continues to move with the negative pressure drum 208.

[0049] When the cigarette without a nozzle moves to the second cigarette-taking assembly 302, the shovel teeth on the second cigarette-taking assembly 302 remove the cigarette without a nozzle from the negative pressure drum 208. The cigarette without a nozzle falls into the channel of the second cigarette-taking assembly 302. The second air-blowing assembly 303 at the end of the channel blows high-pressure air pulsed by the solenoid valve onto the cigarette without a nozzle. The cigarette without a nozzle accelerates axially away from the second cigarette-taking assembly 302 and enters the cigarette guide rail 304. After the cigarette without a nozzle moves below the pressure roller 305, the pressure roller 305 presses the cigarette without a nozzle and it continues to move forward. At the same time, the rotating cutter 308 in the cigarette guide rail 304 cuts the cigarette paper of the cigarette without a nozzle longitudinally. The paper suction roller 311 and the pressure roller 305 rotate in the same direction. The positive and negative pressure air valves 312 control the rotation of the paper suction roller 311. When the cigarette moves to the lower position, negative pressure is applied; when it rotates to the upper right, positive pressure is applied. After the cigarette without a mouthpiece leaves the cigarette guide rail 304, the cigarette paper is attracted to the suction roller 311 by the negative pressure and rotates with it. When it moves to the upper right, positive pressure is applied, and the cigarette paper is blown away from the suction roller 311 and enters the cigarette paper conveying pipe 317. The cigarette paper conveying pipe 317 is connected to the filter cigarette paper collection bin 226. After passing through the cigarette paper conveying pipe 317, the cigarette paper falls into the filter cigarette paper collection bin 226. Since the suction roller 311 is circular, after the cigarette paper is attracted to the circumference, the tobacco shreds detach from the cigarette paper and fall into the tobacco shred collection bin 227 below. The tobacco baffle 316 can guide the tobacco shreds to fall accurately into the tobacco shred collection bin 227. The drive motor 315 transmits power to the pressure roller 305, the cutter 308 and the suction roller 311 via the round belt 318.
