Description

Technical Field

[0002] Cigarettes can be divided into paper-rolled cigarettes and leaf-rolled cigarettes (cigars) based on the rolling material. Here, we're primarily referring to paper-rolled cigarettes: tobacco of varying thicknesses rolled into a special paper. Based on the shape of the cigarette, they can be divided into regular cigarettes (plain cigarettes, made by rolling paper and tobacco directly) and filter cigarettes (regular cigarettes with a filter tip attached and capped with tipping paper).

[0003] Cigarette production primarily involves three processes: cutting, rolling, and packaging. These processes encompass raw material processing, rolling into shape, and packaging finished products. During the rolling process, unsatisfactory rolls can occur, such as skewed labels on cigarettes. These unsatisfactory residual cigarettes require recycling.

[0004] In the prior art, generally include Figure 1 Two tobacco recovery methods are shown: Method (1) uses a cutter to axially cut the cigarette between the filter end and the tobacco end. This method is prone to contamination of the tobacco and can easily pop the popping beads in cigarettes with popping beads. Method (2) uses a blowing mechanism to blow air from one side of the filter end, blowing the tobacco out the other end. The arrow in the figure indicates the blowing direction. This method has the problem of difficult alignment, and the tobacco in cigarettes with popping beads is difficult to blow out due to the obstruction of the popping beads.

[0005] Therefore, it is necessary to improve the method of tobacco recycling and propose a corresponding tobacco recycling device. Utility Model Content

DETAILED DESCRIPTION

[0039] Example 1

[0040] like Figure 2 、 Figures 10 to 12 As shown, the online non-destructive tobacco recovery device for the tobacco roulade assembly includes an air-blast separation mechanism 4 mounted on a transfer drum 3. The transfer drum 3 sequentially transfers the residual tobacco and adjusts the position and direction of the residual tobacco. The air-blast separation mechanism 4 performs an air-blast operation on the residual tobacco at the corresponding position on the transfer drum 3, that is, a needle-shaped air-blast needle 404 is used to blow air into the residual tobacco to blow out the tobacco in the residual tobacco. The residual tobacco involved in this application has the same structure as the cigarette in the prior art, including a filter end 100 and a tobacco end 200. The filter end 100 and the tobacco end 200 are different colors, with the filter end 100 usually being yellow and the tobacco end 200 usually being white.

[0041] like Figure 2 、 Figure 12 As shown, the air-blast separation mechanism 4 includes an air-blast needle 404 driven by a second cylinder 402 to move up and down. The air-blast needle 404 presses down and penetrates the filter end 100 of the residual smoke, and the position where the air-blast needle 404 penetrates the residual smoke is close to the tobacco end 200 of the residual smoke. Air is blown to the corresponding air-blast needle 404 through the connecting tube 406, so that the air-blast needle 404 blows out the tobacco at the tobacco end 200. Figure 2 The arrow in the middle indicates the blowing direction.

[0042] For details, please refer to Figure 10 、 Figure 11 The transfer drum 3 includes a transfer wheel 301 driven to rotate by a driving assembly. The transfer wheel 301 is provided with a slot 302 for clamping the residual cigarette. The transfer wheel 301 is driven by the driving assembly to rotate, so that the slot 302 of the transfer wheel 301 clamps the residual cigarette in the silo and moves with the rotation of the transfer wheel 301, thereby realizing the sequential transmission of the residual cigarette.

[0043] In addition, the width of the transfer wheel 301 is at least greater than the length of a residual cigarette. The same card slot 302 is divided into a first work station and a second work station. The longitudinal projections of the residual cigarettes in the first work station and the second work station may partially overlap or may not overlap, but it is necessary to ensure that the residual cigarette can have a sufficiently long moving stroke in the card slot 302 for position adjustment.

[0044] Air blow pipe 1 306 and air blow pipe 2 308 are mounted on either side of the transfer wheel 301. A color sensor 307 is located between air blow pipe 1 306 and air blow pipe 2 308 on the transfer wheel 301, close to air blow pipe 2 308. A photoelectric sensor 309 is also located on the transfer wheel 301. As the transfer wheel 301 rotates, the residual smoke trapped on the transfer wheel 301 passes through air blow pipe 1 306, color sensor 307, air blow pipe 2 308, photoelectric sensor 309, and air-explosion separation mechanism 4. Air-explosion separation mechanism 4 is equipped with air-explosion needles 404 at the first and second positions of the slot 302, respectively.

[0045] When the transfer wheel 301 rotates and engages residual cigarettes from the hopper for transfer, the residual cigarettes may be in the first station or the second station in the card slot 302, and the positions of the filter end 100 and the tobacco end 200 are random. In order to limit the position of the residual cigarette and thus improve the accuracy of the air-blasting needle 404 penetrating the residual cigarette position, the residual cigarette in the first station is blown to the second station via the blow pipe 1 306. Since the filter end 100 and the tobacco end 200 have different colors, after detection by the color sensor 307, the residual cigarette that does not meet the preset color of the second station is blown to the first station via the blow pipe 2 308. That is, when the color sensor 307 detects that the color of the residual cigarette in the detection area is yellow, the blow pipe 2 308 is activated to blow the residual cigarette to the first station. Then, the photoelectric sensor 309 detects whether there is residual cigarette in the first station or the second station and triggers the air-blasting needle 404 at the corresponding position to perform an air-blast operation. At this time, no matter the residual smoke is in the first or second station, the tobacco end 200 of the residual smoke is close to the edge of the transfer wheel 301. When the photoelectric sensor 309 detects residual smoke in the detection area, it triggers the air-blasting needle 404 at the corresponding position to perform an air-blasting operation.

[0046] Furthermore, the first air blower tube 306, the color sensor 307, the second air blower tube 308, and the photoelectric sensor 309 are all mounted on a support frame 310. The support frame 310 contacts the sidewall of the transfer wheel 301 and is used to limit the residual smoke on the transfer wheel 301. It should be noted that the contact between the support frame 310 and the sidewall of the transfer wheel 301 does not affect the normal rotation of the transfer wheel 301. It only serves to limit the residual smoke on the transfer wheel 301, preventing the first air blower tube 306 or the second air blower tube 308 from blowing the residual smoke away from the transfer wheel 301.

[0047] The drive assembly includes a second motor 303, a driving wheel 304, and a driven wheel 305. The driving wheel 304 is driven to rotate by the drive end of the second motor 303. The driving wheel 304 meshes with the driven wheel 305, and the driven wheel 305 is connected to the transmission wheel 301. The structure in which the second motor 303 drives the transmission wheel 301 to rotate through the driving wheel 304 and the driven wheel 305 is a conventional structure for mechanical motion and will not be described in detail here.

[0048] Please refer to Figure 12 The air-blast separation mechanism 4 further includes a mounting frame 401, one end of which is connected to the housing 11, and a second cylinder 402 is mounted on the other end. The telescopic end of the second cylinder 402 is connected to a lifting block 403. One end of an air-blast needle 404 passes through the lifting block 403 to pierce the residual smoke, and the other end is connected to a connecting pipe 406. The mounting frame 401 is used to mount the second cylinder 402 above the transfer drum 3, facilitating the air-blast needle 404 to perform an air-blast operation on the residual smoke.

[0049] In addition, there are at least two air-blasting needles 404 distributed relatively to each other, and a pressing block 405 for pressing the residual smoke filter end 100 is arranged between the two air-blasting needles 404. The bottom of the pressing block 405 is provided with a pressing groove adapted to the filter end 100. Furthermore, the length of the pressing block 405 below the lifting block 403 is longer than the length of the air-blasting needle 404 below the lifting block 403. By pressing the filter end 100 through the pressing block 405, the displacement of the residual smoke can be avoided, which facilitates the air-blasting needle 404 to penetrate into the filter end 100.

[0050] In a specific embodiment, two groups of air-blasting needles 404 are provided in front and back, and each group includes two air-blasting needles 404 provided on the left and right, which can simultaneously perform air-blasting operations on the residual smoke in the two card slots 302, and can effectively improve the efficiency of tobacco recovery.

[0051] Furthermore, the connecting pipe 406, the air blowing pipe 1 306, and the air blowing pipe 2 308 are all connected to the air blowing equipment (not shown in the figure) through the air pipe to meet the air blowing demand of the recovery device.

[0052] like Figure 3 、 Figure 4As shown, in order to centrally process the blown tobacco, the transfer wheels 301 are located on both sides of the air-blast separation mechanism 4. The transfer wheels 301 collect the tobacco blown out by the air-blast separation mechanism 4 through pipes and make the tobacco fall into the reflux channel 7. The reflux channel 7 is arranged inside the housing 11. The housing 11 is also equipped with an electric control box 6. The reflux channel 7 is connected to the negative pressure suction mechanism 14. A CCD detection mechanism 10 is arranged between the reflux channel 7 and the negative pressure blowing mechanism 14. The negative pressure suction mechanism 14 sucks out the tobacco in the reflux channel 7 for centralized recycling and processing. The CCD detection mechanism 10 is used to detect whether there are impurities such as small pieces of paper in the recycled tobacco.

[0053] In addition, the transfer drum 3 and the air-blast separation mechanism 4 are both mounted on a housing 11. A protective plate 12 is mounted on the housing 11 to cover the transfer drum 3 and the air-blast separation mechanism 4. A waste hopper 5 for collecting waste is also mounted on the housing 11. The blown-out tobacco is recovered through a reflux channel 7. The remaining tobacco from the air-blast on the transfer drum 301 falls into the waste hopper 5 as the transfer wheel 301 rotates, where it is then drained to a collection box (not shown).

[0054] Example 2

[0055] like Figure 3 、 Figure 4 As shown, the structure of this embodiment is basically the same as that of the first embodiment, except that the recovery device in this embodiment further includes a pretreatment mechanism 1, a lifting mechanism 2 and an elevator 13, the lifting mechanism 2 is arranged between the pretreatment mechanism 1 and the transfer drum 3, and the elevator 13 is used to lift and transfer the residual smoke to the pretreatment mechanism 1.

[0056] On the one hand, if Figures 5 to 7 As shown, the pre-treatment mechanism 1 is used to filter the residual smoke to be processed. The pre-treatment mechanism 1 includes a swingable feed hopper 101 , which is used to receive the residual smoke transmitted by the elevator 13 .

[0057] The residual smoke falls into the feed hopper 101 through the feed port of the feed hopper 101, is separated after being shaken by the grid 102, and is then filtered by the filter plate 103, so that the waste tobacco passes through the filter plate 103 and falls into the waste smoke pipe 9 through the guide plate 106. The residual smoke to be processed retained on the filter plate 103 is guided by the filter plate 103 to the lifting mechanism 2.

[0058] First, if Figure 5 As shown, the feed port of the feed hopper 101 is equipped with a grille 102. One end of the grille 102 is hinged to the feed hopper 101, and the other end is mounted on the feed hopper 101 and is driven by the shaking assembly 8 to shake up and down. The shaking grille 102 is used to disperse the large amount of residual smoke transmitted by the elevator 13, facilitating filtration by the filter plate 103 inside the feed hopper 101.

[0059] Please refer to Figure 6 The shaking assembly 8 includes a cylinder 1 801, a slide 802, a fixed plate 803, a connecting rod 804, and a limit plate 805. The fixed plate 803 is connected to the side wall of the feed hopper 101. The slide 802 is connected to the grille 102 via the connecting rod 804. The limit plate 805 is installed on the fixed plate 803. The limit plate 805 is provided with a groove for engaging the connecting rod 804. The cylinder 1 801 drives the slide 802 to reciprocate on the fixed plate 803, thereby driving the grille 102 to shake up and down. The limit plate 805 is arranged at a right angle to the fixed plate 803. The groove structure of the limit plate 805 engages the connecting rod 804, so that the limit plate 805 can not only limit the upper and lower limits of the slide 802, but also guide the up and down movement of the connecting rod 804, thereby improving the stability of the movement of the connecting rod 804.

[0060] Secondly, if Figure 5 As shown, the feed hopper 101 is internally provided with a filter plate 103. The filter plate 103 is tilted and guides the residual smoke in the feed hopper 101 into the lifting mechanism 2. The sidewall of the feed hopper 101 is provided with a through slot for the filter plate 103 to extend out. The feed hopper 101 is installed with a baffle 104 at the position of the through slot. The filter plate 103 is used to filter waste tobacco mixed with the residual smoke. The residual smoke retained on the filter plate 103 falls into the lifting mechanism 2 through the tilted filter plate 103. The baffle 104 is used to prevent the residual smoke on the filter plate 103 from falling directly into the residual smoke being transported in the lifting mechanism 2, thereby affecting the horizontal arrangement and transportation of the residual smoke.

[0061] Finally, the discharge port at the bottom of the feed hopper 101 is provided with a guide plate 106, which is connected to the waste tobacco pipe 9. The waste tobacco passes through the filter plate 103 and falls into the guide plate 106. The bottom of the guide plate 106 is tilted to facilitate guiding the waste tobacco into the waste tobacco pipe 9. The waste tobacco pipe 9 is connected to the waste tobacco box (not shown in the figure) for centralized collection of waste tobacco.

[0062] In addition, please refer to Figure 7 To achieve the swinging of the feed hopper 101, the feed hopper 101 is mounted on the housing 11 via a fixed rod 109. The feed hopper 101 and the fixed rod 109 are movably connected via a rotating shaft. A swing rod 108 is also connected to the feed hopper 101, and the other end of the swing rod 108 is connected to the driving end of the motor 105 via a connecting plate 107. The motor 105 drives the connecting plate 107, thereby driving the swing rod 108 to swing, allowing the feed hopper 101 to swing back and forth around the rotating shaft, facilitating the passage of residual smoke through the grille 102 into the feed hopper 101, and effectively improving the filtration efficiency of the filter plate 103.

[0063] On the other hand, Figure 8 、 Figure 9As shown, the lifting mechanism 2 is used to sequentially and horizontally transfer the residual smoke filtered out of the pre-treatment mechanism 1 to the transfer drum 3. The lifting mechanism 2 includes two side plates 201 arranged opposite to each other, a conveyor belt 204, a gear set 203, and a plurality of rotating rollers 202. The conveyor belt 204 is arranged between the two side plates 201. The rotating rollers 202 installed on the side plates 201 form a transmission track. The rotating rollers 202 rotate by driving the gear set 203 driven by the drive motor, thereby driving the transmission of the conveyor belt 204. The rotation of the gear set 203 driven by the drive motor drives the rotating rollers 202 to rotate, thereby driving the transmission of the conveyor belt 204. This is a conventional mechanical structure and will not be described in detail here. It should be noted that a receiving plate 205 is provided on the conveyor belt 204 to arrange the residual smoke horizontally. The width of the receiving plate 205 is adapted to the diameter of the residual smoke to ensure that the residual smoke is horizontally distributed on the receiving plate 205.

[0065] like Figure 8 、 Figure 9 As shown, the structure of this embodiment is basically the same as that of the second embodiment, the difference being that the lifting mechanism 2 of this embodiment further includes a sensing member 206, a blowing member 207 and a guide plate 208, wherein the lifting mechanism 2 includes a material receiving side and a material feeding side, and the sensing member 206 is arranged on the material receiving side of the lifting mechanism 2, and is used to detect the amount of residual smoke transmitted by the pretreatment mechanism 1. When the amount of residual smoke transmitted from the pretreatment device 1 to the lifting mechanism 2 is too much, the swinging and shaking of the pretreatment mechanism 1 is suspended, so that the pretreatment mechanism 1 no longer feeds material to the lifting mechanism 2, thereby avoiding a large amount of residual smoke from accumulating at the lifting mechanism 2.

[0066] In a specific embodiment, the sensing element 206 includes a proximity switch and a swing rod. When the amount of residual smoke on the material receiving side of the lifting mechanism 2 is small, the swing rod is in a stationary state due to its own gravity. When the amount of residual smoke increases to a certain amount, the swing rod will swing accordingly. When the proximity switch senses the swinging swing rod, the pretreatment mechanism 1 is controlled to stop swinging and shaking.

[0067] The air blowing member 207 is located on the feed side of the lifting mechanism 2. It blows air into the residual smoke, aligning it with the conveyor belt 204 on the feed side. The air blowing member 207 pre-positions the residual smoke by blowing it to the same side for pre-positioning. The air blowing pipe 1 306 on the transfer wheel 301 then blows air into the residual smoke for secondary positioning, ensuring that the residual smoke is aligned with the same side and in close contact with the sidewall of the support frame 310. This facilitates the color sensor 307 to detect the color of the residual smoke within the detection area. It should be noted that the air blowing member 207 and the air blowing pipe 1 306 are located on the same side.

[0068] The guide plate 208 is installed on the feeding side of the lifting mechanism 2 to guide the residual smoke to the slot 302 of the transfer wheel 301. The guide plate 208 can realize the rapid transfer of the residual smoke between the lifting mechanism 2 and the transfer drum 3.

[0069] Working principle: The online non-destructive tobacco recovery device of the tobacco rolling machine unit lifts the residual tobacco to be processed to the top of the pretreatment device 1 through the elevator 13, and the residual tobacco falls into the feed hopper 101 due to gravity. At this time, the residual tobacco that falls in concentrated form can be dispersed by the up and down shaking grid 102 and the swinging feed hopper 101, thereby accelerating the residual tobacco from falling into the feed hopper 101.

[0070] The waste tobacco is filtered through the built-in filter plate 103, and falls into the guide plate 106 and into the waste tobacco pipe 9. It is collected and processed by the waste tobacco box. The residual tobacco retained on the filter plate 103 falls into the lifting mechanism 2 through the inclined filter plate 103.

[0071] The lifting mechanism 2 uses the existing lifting principle to drive the conveyor belt 204 through the driving motor to realize the sequential and horizontal transmission of residual smoke. At the same time, the sensor 206 detects the amount of residual smoke in the lifting mechanism 2. When it is detected that the amount is too much, the feeding is suspended to avoid excessive accumulation of residual smoke in the lifting mechanism 2.

[0072] During the feeding process of the lifting mechanism 2 , the residual smoke is blown to the same side by the blowing member 207 , and then transferred to the transfer drum 3 by the guide plate 208 and connected by the card slot 302 .

[0073] The transmission wheel 301 rotates through the cooperation between the second motor 303, the driving wheel 304, and the driven wheel 305, achieving the transmission of residual smoke. Following the rotation of the transmission wheel 301, the residual smoke passes through the first air blow pipe 306, the color sensor 307, the second air blow pipe 308, the photoelectric sensor 309, and the air explosion separation mechanism 4.

[0074] Air blow pipe 1 306 blows air into the residual smoke, repositioning it to ensure it is on the same side and close to the sidewall of the support frame 310. The color sensor 307 then detects the residual smoke. When the color sensor 307 detects yellow residual smoke within the detection area, air blow pipe 2 308 is activated to blow the residual smoke to the other side of the transfer wheel 301. When the color sensor 307 detects white residual smoke within the detection area, air blow pipe 2 308 is deactivated, keeping the residual smoke in place. A photoelectric sensor 309 then detects whether residual smoke is present in the first or second station and triggers the air-blasting needle 404 in the corresponding position to perform an air-blast operation. At this point, regardless of whether the residual smoke is in the first or second station, the tobacco end 200 of the residual smoke is close to the edge of the transfer wheel 301. When the photoelectric sensor 309 detects residual smoke within the detection area, the air-blasting needle 404 in the corresponding position is triggered to perform an air-blast operation.

[0075] The air-blast operation is as follows: the lifting block 403 is driven downward by the second cylinder 402, so that the pressing block 405 presses and fixes the filter end 100 of the residual smoke, and at the same time the air-blasting needle 404 penetrates the corresponding residual smoke. According to the detection result of the photoelectric sensor 309, the connecting tube 406 at the corresponding position is triggered to ventilate the corresponding air-blasting needle 404, and air is blown toward the tobacco end 200 through the air-blasting needle 404 to blow out the tobacco completely.

[0076] The blown tobacco shreds fall into the reflux channel 7 through the pipe, and then the tobacco shreds in the reflux channel 7 are sucked out by the negative pressure blowing mechanism 14 for centralized recovery and treatment.
