[0002] In the process of cigarette production, a certain number of defective cigarettes are often produced. In order to improve the utilization rate of raw materials, the tobacco in the defective cigarettes needs to be recycled. In the process of broken cigarette recycling, steam rehydration and mechanical cutting are needed to separate the tobacco, and directly recycling the cigarette with the filter rod containing the burst beads or powder flavor will mix the burst beads or powder flavor into the tobacco, affecting the purity of the tobacco and the process stability, combustion stability and the like of the cigarette. Therefore, when recycling the cigarette with the filter rod containing the flavor, the filter rod needs to be peeled off first, and then the broken cigarette recycling process is performed.

[0036] To address the aforementioned issues, this application provides a self-identifying cigarette filter separation device that can automatically identify the cigarette end and the filter end, completing the cigarette filter separation process without manual pre-sorting, effectively reducing labor intensity. The device features a clever structural design and reliable operation. Simultaneously, it effectively prevents flavor capsules or powdered flavorings from mixing into the tobacco, ensuring the purity of the tobacco during cigarette recycling.

[0037] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0038] Figure 1 is an exploded view of a self-identifying cigarette filter separation device component according to an embodiment of the present application. Referring to Figure 1 In embodiment 1, the self-identifying cigarette filter separation device according to an embodiment of the present application includes a driving component 1, an arrangement component 2, an identification and pre-cutting component 3, a separation component 4, a rack and auxiliary component 5, the driving component 1 is installed on the platform 51 of the rack and auxiliary component 5, the separation component 4 is installed on the vertical plate 52, the arrangement component 2 and the drum 16 and the identification and pre-cutting component 3 are installed on the vertical plate 52; the arrangement component 2, the identification and pre-cutting component 3 and the separation component 4 are arranged along the circumference of the drum 16 in sequence, the cigarette 7 is positioned and arranged by the arrangement component 2, so that the cigarette 7 is more convenient to enter the drum 16; the driving component 1 drives the drum 16 to rotate, the identification and pre-cutting component 3 can identify and adjust the cigarette, accurately cut the cigarette and the filter, the separation component 4 effectively separates the cut cigarette and the filter, and the rack and auxiliary component 5 effectively collects the separated cigarette and filter.

[0039] In Example 2, the pre-cutting component 3 in the application includes a negative pressure positioning block 31, an arc-shaped plate 32, a positive pressure blowing block 33, a sensor support 34, a color sensor 35, a pressure roller support 36, a pressure roller 37, a blade 38, a gas connector 39, a negative pressure electromagnetic valve 391, and a positive pressure electromagnetic valve 392. The negative pressure positioning block 31 is installed on the vertical plate 52. The arc-shaped plate 32 is installed at the rear end of the negative pressure positioning block 31. The positive pressure blowing block 33 is installed at the front end of the arc-shaped plate 32. The color sensor 35 is installed on the positive pressure blowing block 33 through the sensor support 34. The color sensor 35 can effectively distinguish the positions of the cigarette end and the filter end. The pressure roller support 36 is installed on the left side of the arc-shaped plate 32. Two pressure rollers 37 are installed on the pressure roller support 36. The pressure rollers 37 can press and stabilize the cigarettes. The blades 38 are installed on the outer sides of the two pressure rollers 37. The blades 38 can cut the cigarettes and filters at the corresponding positions. The negative pressure screw hole 311 is provided in the middle of the negative pressure positioning block 31. The gas connector 39 is connected in the negative pressure screw hole 311 and connected to the negative pressure electromagnetic valve 391 installed on the back of the vertical plate 52 through a gas pipe. The negative pressure electromagnetic valve 391 is connected to the external negative pressure gas. The positive pressure screw hole 331 is provided in the middle of the positive pressure blowing block 33. The gas connector 39 is connected in the positive pressure screw hole 331 and connected to the positive pressure electromagnetic valve 392 installed on the back of the vertical plate 52 through a gas pipe. The positive pressure electromagnetic valve 392 is connected to the external positive pressure gas. The positive pressure screw hole 331 of the positive pressure blowing block 33 is blown up by the positive pressure electromagnetic valve 392. The negative pressure screw hole 311 of the negative pressure positioning block 31 is sucked by the negative pressure electromagnetic valve 391. Thus, the cigarettes 7 close to the end face of the positive pressure blowing block 33 are blown along the arc-shaped plate 32 to the end face of the negative pressure positioning block 31 at the other end of the cigarettes 7, effectively pushing the movement of the cigarettes 7. At the same time, the negative pressure electromagnetic valve 391 and the positive pressure electromagnetic valve 392 are instantaneously connected. After being connected, they are reset, effectively avoiding affecting the positions of the front and rear cigarettes 7.

[0040] In Example 3, the adjustment pad 361 is provided between the pressure roller support 36 and the arc-shaped plate 32 in the application. By changing the thickness of the adjustment pad 361, the pressing force of the pressure roller 37 on the cigarettes is effectively changed, thereby adjusting the cutting depth of the blade 38 and reducing the damage of the blade 3 to the tobacco.

[0041] In Example 4, the outer sides of the two pressure rollers 37 are respectively provided with two blade holes 321. The blade 38 is placed in the blade hole 321 and fixed on the arc-shaped plate 32 through a screw, so that the blade 38 is convenient and fast to replace.

[0042] In example 5, the driving component 1 in the application comprises a reduction motor 11, a first pulley 12, a second pulley 121, a synchronous belt 13, a transmission shaft 14, a drum lock sleeve 15, a drum 16, a motor support 17, a bearing seat 18, and an end cover 19. The motor support 17 is installed on the platform 51 by screws. The reduction motor 11 is installed on the motor support 17 by screws. The first pulley 12 is installed on the shaft of the reduction motor 11. The first pulley 12 is fixed on the shaft head of the reduction motor 11 by the end cover 19, screws, and a flat key. The drum 16 is installed on the platform 51 by the bearing seat 18, the transmission shaft 14, and the drum lock sleeve 15. One side of the drum 16 is provided with the drum lock sleeve 15. The transmission shaft 14 penetrates the drum 16 and the drum lock sleeve 15, and the transmission shaft 14, the drum lock sleeve 15, and the drum 16 are connected into an integrated whole by screws. Bearings are installed on the transmission shaft 14 on both sides of the drum 16. The bearings are arranged in the bearing seat 18. The bearing seat 18 is fixed on the platform 51 by screws. The second pulley 121 is installed on the transmission shaft 14. The second pulley 121 is fixed on the shaft head of the transmission shaft 14 by the end cover 19, screws, and a flat key. The second pulley 121 is linked with the first pulley 12 through the synchronous belt 13, so that the drum 16 and the second pulley 121 rotate synchronously. The second pulley 121 is driven by the first pulley 12, and the drum 16 rotates by the rotation of the reduction motor 11.

[0043] In example 6, the arrangement component 2 in the application comprises a hopper 21, a hopper door 22, a reverse roller 23, a pneumatic motor 24, an air valve 25, and a spring 26. The hopper door 22 is hingedly connected to one side of the hopper 21 to prevent cigarettes 7 from leaking out. The hopper 21 is installed on the vertical plate 52 by screws penetrating through the through hole 211 and the first sleeve 27. The pneumatic motor 24 is installed on the vertical plate 52. The reverse roller 23 is installed on the pneumatic motor 24. The rotation direction of the reverse roller 23 is the same as that of the drum 16, which effectively prevents excess cigarettes 7 from being blocked when entering the arc-shaped plate 32. Excess cigarettes 7 not adsorbed in the sink groove 161 will be pushed to the rear by the reverse roller 23. The pneumatic motor 24 is connected to the positive pressure air pipe 28 and is driven by air pressure. The air valve 25 is installed on the vertical plate 52 by the spring 26 and screws. The air valve 25 has a circular arc waist structure. One side is a negative pressure groove 251, and the other side is connected to an external negative pressure air pipe 252. The working position of the air valve 25 is from the bottom of the hopper 21 to the entrance of the arc-shaped plate 32, so that the suction hole 163 of the drum 16 has negative pressure at this operating position. The air valve 25 is installed on the vertical plate 52 in a floating manner, which effectively ensures that the end face of the negative pressure groove 251 tightly fits the end face of the negative pressure blind hole 162 of the drum 16, thereby ensuring the sealing performance.

[0044] In the embodiment 7, the separating component 4 in the present application comprises a separating block 41, an anti-rotation guide rail 42, a guide rail frame 43, and a shearing guide rail 44. The separating block 41 and the shearing guide rail 44 are combined to form a separating assembly. A second sleeve 45 is arranged between the separating block 41 and the shearing guide rail 44. A pair of separating assemblies are symmetrically arranged on both sides of the drum 16. The separating assemblies are installed on a platform 51 to achieve support and positioning. The anti-rotation guide rail 42 is arranged outside the separating assemblies and is installed on a vertical plate 52 through the guide rail frame 43. The shearing guide rail 44 and the anti-rotation guide rail 42 effectively press the cigarette 7 in the sink groove 161 and make it slide in the shearing guide rail 44 and the anti-rotation guide rail 42, effectively preventing the cigarette 7 from deviating from the cut position and preventing the cigarette 7 from loosening during breaking and shearing. The separating block 41 is designed as a circular arc structure with a thinner inner side and a thicker outer side close to the drum 16. The filter end of the cigarette 7 first contacts the outer side of the separating block 41. The cigarette 7 will be broken at the cut. Then, the cigarette 7 continues to move with the drum 16. When the lower part of the separating block 41, the angle between the drum 16 and the separating block 41 gradually decreases to a negative value. The shearing effect formed will completely separate the filter end of the cigarette 7 from the cigarette end, thereby completely cutting the paper connecting the filter end and the cigarette end together during breaking. In the embodiment 8, the lower end of the separating block 41 is provided with a waist hole 411. The separating block 41 is installed on the platform 51 through the waist hole 411 and a screw. The waist hole 411 can adjust the radial distance between the separating block 41 and the drum 16, thereby changing the separation performance and achieving the best shearing effect of the separating block 41. Meanwhile, the waist-shaped hole provided on the anti-rotation guide rail 42 can adjust the pressing force of the anti-rotation guide rail 42 on the cigarette 7.

[0045] In the embodiment 9, the rack and auxiliary components 5 in the present application comprise a platform 51, a vertical plate 52, a platform support 53, a filter funnel 54, a cigarette guide plate 55, a filter collection barrel 56, and a cigarette collection barrel 57. The platform 51 is installed with the platform support 53 at the lower end and the vertical plate 52 at the upper end. A square hole 511 is arranged on the platform 51. The drum 16 is installed in the square hole 511. Two filter funnels 54 are installed at the lower end of the square hole 511 on both sides of the platform 51. A cigarette guide plate 55 is arranged between the two filter funnels 54. A filter collection barrel 56 is arranged below the filter funnel 54, so that the cut filter falls into the filter collection barrel 56 through the filter funnel 54. A cigarette collection barrel 57 is arranged at the lower end of the cigarette guide plate 55, so that the cut cigarette falls into the cigarette collection barrel 57 through the cigarette guide plate 55.

[0046] In Example 10, the second pulley 121 is provided with a speed measuring screw 63 in a factor relationship with the sink groove 161, and an optical sensor 61 is provided beside the second pulley 121. The optical sensor 61 is fixed on the platform 51 by a optical sensor support 62 and a screw. The optical sensor 61 can calculate the rotating speed of the drum 16 according to the number of pulses formed by the rotation of the speed measuring screw 63, and feedback to the PLC controller to adjust the on time of the negative pressure electromagnetic valve 391 and the positive pressure electromagnetic valve 392 to adapt to different production speeds.

[0047] In Example 11, the drum 16 is provided with a plurality of sink grooves 161, and each sink groove 161 on one side of the drum is provided with a negative pressure blind hole 162. Two air suction holes 163 are provided on one sink groove 161 and communicate with the negative pressure blind hole 162. The negative pressure groove 251 of the air valve 25 is in close contact with the end face of the negative pressure blind hole 162 to form a local negative pressure air path. The cigarette 7 under the action of gravity will be close to the circumferential surface of the drum 16. The external negative pressure air is transmitted to the air suction hole 163 of the sink groove of the drum 16 through the air valve 25, and a local negative pressure is generated at the air suction hole 163 in the sink groove 161. The cigarette 7 under the action of negative pressure will be closely attached to the sink groove 161 to avoid falling off. Each sink groove 161 will rotate with the drum 16 after sucking a cigarette 7.

[0048] Working process: The cigarette 7 is put into the hopper 21, and the hopper door 22 axially positions the cigarette 7. The cigarette 7 is close to the circumferential surface of the drum 16. Each sink groove 161 on the drum 16 sucks a cigarette 7 and rotates with the drum 16. The excess cigarettes 7 not adsorbed in the sink groove 161 are pushed to the back by the reverse roller 23. The end face of the negative pressure groove 251 of the air valve 25 is in close contact with the end face of the negative pressure blind hole 162 of the drum 16.

[0049] After the cigarette 7 enters the arc plate 32, the color sensor 35 identifies the filter end and the cigarette end of the cigarette 7. After the filter end of the cigarette 7 is identified, the color sensor 7 does not act, and the cigarette 7 continues to move. When the cigarette end of the cigarette 7 is identified, the color sensor 35 feeds back to the PLC controller, and the positive pressure electromagnetic valve 392 is turned on. The positive pressure gas is transmitted to the through threaded hole 331 of the positive pressure blowing block 33 through the air pipe after passing through the positive pressure electromagnetic valve 392. The positive pressure gas acts on the end face of the cigarette end of the cigarette 7. The cigarette 7 moves axially in the cigarette sink groove 161 to the negative pressure positioning block 31. At the same time, the negative pressure electromagnetic valve 391 is turned on. The negative pressure gas is transmitted to the through threaded hole 311 of the negative pressure positioning block 31 through the negative pressure electromagnetic valve 391. The negative pressure gas acts on the end face of the filter end of the cigarette 7, so that the cigarette 7 moves completely to the end face of the negative pressure positioning block 31. The filter end of the cigarette 7 is attached to the end face of the negative pressure positioning block 31. The negative pressure electromagnetic valve 391 and the positive pressure electromagnetic valve 392 are instantaneously turned on and reset after being turned on. The positions of the front and rear cigarettes 7 are not affected. After the cigarette 7 moves to the left end of the arc plate 32, the two pressure wheels 37 press the cigarette 7 tightly in the cigarette sink groove 161. The pressing force is changed by changing the thickness of the adjusting gasket 361. At the same time, the blades 38 on both sides pre-cut the connection between the cigarette end and the filter end. The front blade 38 pre-cuts the cigarette 7 identified by the color sensor 35 at the filter end. The rear blade 38 pre-cuts the cigarette 7 identified by the color sensor 35 at the cigarette end. When the cigarette end passes through the blade 38, the cigarette end is located between the two blades 38.

[0050] The cigarette 7 continues to move to the separation component 4. The cigarette is pressed in the cigarette sink groove 161 by the shearing guide rail 44 and the anti-rotation guide rail 42, and slides in the shearing guide rail 44 and the anti-rotation guide rail 42. Since the separation block 41 is a circular arc structure with a thinner inner side and a thicker outer side in the direction of the drum 16, the filter end of the cigarette 7 first contacts the outer side of the separation block 41. The cigarette 7 will be broken at the cut. When the cigarette 7 continues to move to the lower part of the separation block 41, the angle formed by the drum 16 and the separation block 41 gradually decreases to a negative value. The shearing action formed completely separates the filter end of the cigarette 7 from the cigarette end. The filter end falls into the filter funnel 54 below the drum 16 and finally into the filter collection barrel 56. The cigarette end naturally falls to the cigarette guide plate 55 after leaving the shearing guide rail 44 and the anti-rotation guide rail 42 and enters the cigarette collection barrel 57.
