Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a multi-path longitudinal cutting device for cigarettes. Background Technology

[0002] During cigarette production, some cigarettes that do not meet quality standards are inevitably generated, such as those with insufficient tobacco, creases, or substandard adhesive. These are commonly referred to as "waste cigarettes." The amount of waste cigarettes is particularly large during the start-up and adjustment phases of cigarette rolling machines. If not properly handled, this not only wastes resources but also impacts the production environment.

[0003] Cigarette manufacturers have two methods for handling waste cigarettes. The traditional method involves dedicated personnel regularly collecting and transporting the waste cigarettes to a waste cigarette processing workshop. The waste cigarette processing equipment separates the tobacco, cigarette paper, and filters, and the tobacco is then recycled and downgraded for reuse. The current method involves installing waste cigarette processing equipment next to the cigarette rolling machine. This equipment uses longitudinal cutting technology to cut the cigarettes lengthwise, separating the tobacco, which is then directly fed into the cigarette rolling machine for reuse. This method does not lower the quality grade of the tobacco, and the moisture content and flavor ratio of the tobacco remain unchanged. However, during use, it has been found that the longitudinal cutting speed is slower than the production speed of the cigarette rolling machine, resulting in low efficiency and often leading to the accumulation of waste cigarettes, which affects the operation of the cigarette production line. Utility Model Content

[0004] This invention provides a multi-path longitudinal cutting device for cigarettes, which solves the problems of slow production speed and low efficiency in the longitudinal cutting of waste cigarettes in the prior art.

[0005] This utility model provides a multi-path longitudinal cutting device for cigarettes, comprising:

[0006] A conveyor belt is configured to transport cigarettes along a first direction, and a plurality of strip grooves are arranged around the conveyor belt, the strip grooves extending along a second direction, each strip groove being used to accommodate one cigarette, the first direction being perpendicular to the second direction;

[0007] Multiple slitting machines are provided, and the multiple slitting machines are spaced apart along a first direction on one side of the conveyor belt. Each slitting machine is provided with a smoke feeding pipe along a second direction, and the smoke feeding pipe is arranged parallel to the cigarette on the conveyor belt.

[0008] Multiple blowing devices are provided, and the multiple blowing devices are spaced apart along a first direction on the other side of the conveyor belt. Each blowing device corresponds to a smoke delivery pipe and is used to blow the cigarettes on the conveyor belt into the slitting machine through the smoke delivery pipe.

[0009] The multi-path longitudinal cutting device for cigarettes provided by this utility model also includes a controller, which is electrically connected to the longitudinal cutting machine and the blowing device respectively.

[0010] The multi-path longitudinal cutting device for cigarettes provided by this utility model also includes a feeding mechanism, which is disposed at one end of the conveyor belt. The discharge end of the feeding mechanism corresponds to the conveyor belt and is used to supply cigarettes to the conveyor belt.

[0011] According to the multi-path longitudinal cutting device for cigarettes provided by this utility model, a hopper is provided between the discharge end of the feeding mechanism and the conveyor belt. The upper port of the hopper corresponds to the discharge end, the lower port of the hopper corresponds to the conveyor belt, and the lower port is a strip-shaped outlet. The length direction of the strip-shaped outlet is the same as the second direction.

[0012] According to the multi-path longitudinal cutting device for cigarettes provided by this utility model, the hopper includes a first cigarette dropping plate and a second cigarette dropping plate. The first cigarette dropping plate and the second cigarette dropping plate are arranged opposite to each other. The first cigarette dropping plate is inclined between the discharge end and the conveyor belt. The second cigarette dropping plate is arranged perpendicular to the conveyor belt. A gap is left between the second cigarette dropping plate and the conveyor belt. A flexible baffle is provided at the bottom of the second cigarette dropping plate. The flexible baffle is used to make the cigarettes fall one by one into the strip groove and pass through the gap.

[0013] The multi-path longitudinal cutting device for cigarettes provided by this utility model also includes a conveying mechanism. The conveying mechanism includes a base and a driving device. Both ends of the base are rotatably provided with transmission wheels. The conveyor belt is sleeved on a pair of transmission wheels.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The following is combined with Figures 1-2 This invention describes a multi-path longitudinal cutting device for cigarettes.

[0026] This embodiment provides a multi-path longitudinal cutting device for cigarettes, including: a conveyor belt 1, a longitudinal cutting machine 2, and a blowing device 3.

[0027] The conveyor belt 1 is configured to transport cigarettes along a first direction. Multiple strip-shaped grooves are arranged around the conveyor belt 1, extending along a second direction. Each strip-shaped groove is used to accommodate one cigarette, and the first direction is perpendicular to the second direction. Figure 1 As shown, by setting the conveyor belt 1 to transport cigarettes in a first direction, such as laterally, and providing strip grooves on the conveyor belt 1 that extend in a second direction, such as longitudinally, it can be ensured that the cigarettes maintain good alignment during transport. The design of each strip groove to accommodate one cigarette can effectively prevent the cigarettes from shaking or shifting in position during transport, thereby reducing damage caused by physical contact, such as tobacco falling off or cigarette paper tearing. This not only improves production efficiency but also ensures product quality.

[0028] Multiple slitting machines 2 are provided, and the multiple slitting machines 2 are spaced apart along one side of the conveyor belt 1 in a first direction. Each slitting machine 2 is provided with a smoke supply pipe 21 along a second direction, and the smoke supply pipe 21 is arranged parallel to the smoke sticks on the conveyor belt 1; for example Figure 1 As shown, multiple slitting machines 2 are spaced apart on one side of the conveyor belt 1 along the first direction, i.e. the conveying direction of the conveyor belt 1, which can process multiple cigarettes at the same time, thereby improving production efficiency. The cigarette feeding pipe 21 is arranged parallel to the cigarettes on the conveyor belt 1 to ensure that the cigarettes smoothly enter the slitting machine 2 from the conveyor belt 1 for processing.

[0029] Multiple blowing devices 3 are provided, and multiple blowing devices 3 are arranged at intervals along the first direction on the other side of the conveyor belt 1. Each blowing device 3 corresponds to a smoke delivery pipe 21 and is used to blow the cigarettes on the conveyor belt 1 into the slitting machine 2 through the smoke delivery pipe 21.

[0030] With this configuration, the multi-path longitudinal cutting device for cigarettes provided by this utility model can simultaneously cut cigarettes by multiple longitudinal cutting machines 2, thereby improving cutting efficiency, significantly increasing cutting speed and production efficiency, shortening the production cycle, and making it suitable for large-scale production needs.

[0031] In this embodiment, a controller is also included. The controller is electrically connected to the slitting machine 2 and the blowing device 3 respectively to meet the needs of automated production.

[0032] In some embodiments, the system further includes a feeding mechanism 4, which is disposed at one end of the conveyor belt 1. The discharge end of the feeding mechanism 4 corresponds to the conveyor belt 1 and is used to provide cigarettes to the conveyor belt 1. A dropping hopper is provided between the discharge end of the feeding mechanism 4 and the conveyor belt 1. The upper port of the dropping hopper corresponds to the discharge end, and the lower port of the dropping hopper corresponds to the conveyor belt 1. The lower port is a strip-shaped outlet, and the length direction of the strip-shaped outlet is the same as the second direction.

[0033] This configuration ensures a continuous supply of cigarettes through the feeding mechanism 4, avoiding production interruptions and improving the continuity and stability of the production line. The coordinated work of the feeding mechanism 4 and the discharge hopper ensures the stability of the cigarettes before they enter the conveyor belt 1, preventing cigarette accumulation and blockage. The design of the strip-shaped outlet ensures the consistency of the direction of the cigarettes when they fall into the conveyor belt 1, preventing disorder and accumulation of cigarettes. At the same time, the discharge hopper can play a certain buffering role, reducing the impact force between the cigarettes and the feeding mechanism 4 and the conveyor belt 1, protecting the cigarettes from damage.

[0034] Optionally, the feeding structure can be a belt elevator, which is inclined and has multiple feeding plates spaced apart on its feeding conveyor belt. The smoke is continuously fed into the discharge hopper through the operation of the feeding conveyor belt.

[0035] like Figures 1-2 As shown, in some embodiments, the hopper includes a first cigarette discharge plate 5 and a second cigarette discharge plate 6. The first cigarette discharge plate 5 and the second cigarette discharge plate 6 are arranged opposite to each other and form a strip-shaped outlet at the bottom. The first cigarette discharge plate 5 is inclined between the discharge end and the conveyor belt 1. The second cigarette discharge plate 6 is arranged perpendicular to the conveyor belt 1. A gap is left between the second cigarette discharge plate 6 and the conveyor belt 1. A flexible baffle 7 is provided at the bottom of the second cigarette discharge plate 6. The flexible baffle 7 can be a brush, which is used to make the cigarettes fall one by one into the strip groove and pass through the gap.

[0036] This design, with the first cigarette drop plate 5 tilted, provides a buffer and guide effect, reducing the impact force between the cigarettes and the feeding mechanism 4 and the conveyor belt 1, protecting the cigarettes from damage. The strip-shaped outlets formed at the bottom of the first and second cigarette drop plates 5 ensure that the cigarettes fall into the conveyor belt 1 in the same direction as the strip groove, avoiding disorder and accumulation of cigarettes. By setting up the flexible baffle 7, cigarettes that are not carried away by the conveyor belt 1 can be blocked and fall into the next groove, thus ensuring that only one cigarette is stored in each strip groove.

[0037] In this embodiment, a conveying mechanism is also included. The conveying mechanism includes a base 8 and a drive device 9. Both ends of the base 8 are rotatably provided with transmission wheels 10. The conveyor belt 1 is sleeved on a pair of transmission wheels 10. The drive device 9 is electrically connected to the controller and is connected to one of the transmission wheels 10. The drive device 9 drives one of the transmission wheels 10 to rotate, thereby driving the conveyor belt 1 to convey cigarettes along the first direction.

[0038] like Figure 1 As shown, the drive device 9 is a motor, and a drive wheel is provided on the power output shaft of the motor. A driven wheel is sleeved on one end of the shaft of the transmission wheel 10. The drive wheel and the driven wheel are connected in a transmission connection. Optionally, both the drive wheel and the driven wheel are gears, and the two achieve meshing transmission. Of course, both the drive wheel and the driven wheel can also be pulleys or sprockets to achieve belt transmission or chain transmission.

[0039] Furthermore, it also includes a baffle 11, which is disposed on the side of the conveyor belt 1 near the blowing device 3, and the height of the baffle 11 from the ground is greater than the height of the cigarette from the ground. With this arrangement, the baffle 11 is slightly higher than the cigarette, which limits the bouncing of the cigarette during movement, prevents the cigarette from falling off the conveyor belt 1, and ensures the stability of the cigarette during the conveying and feeding process into the slitting machine 2.

[0040] In this embodiment, multiple detection sensors 12 are also included. The detection sensors 12 can be proximity sensors, such as photoelectric sensors, which detect the presence or position of an object by emitting and receiving light. The multiple detection sensors 12 are arranged at intervals along one side of the conveyor belt 1 in the first direction. The number of detection sensors 12 is the same as the number of blowing devices 3 and their positions correspond one-to-one. They are used to detect the position of the cigarette. The detection sensors 12 are electrically connected to the controller and can send a stop signal to the controller when the cigarette is conveyed to the cigarette delivery pipe 21. That is, when the cigarette is detected to have moved to the position corresponding to the cigarette delivery pipe 21, the controller sends a stop signal to the controller to stop the drive device 9, so that the conveyor belt 1 stops moving. After that, the controller can control the blowing device 3 to blow the cigarette into the cigarette delivery pipe 21.

[0041] This configuration, through the setting of the detection sensor 12, ensures the precise position of the cigarette before it enters the cigarette delivery pipe 21, avoiding misoperation and equipment damage, and improving the reliability and safety of the system. The linkage between the detection sensor 12 and the controller ensures the continuous and efficient delivery of the cigarette.

[0042] In some embodiments, the blowing device 3 includes an air nozzle corresponding to the smoke delivery pipe 21. The air nozzle can be configured to correspond to the filter tip of the cigarette. When the cigarette needs to be blown, the air nozzle opens, and the airflow blows the cigarette along the smoke delivery pipe 21 into the corresponding slitting machine 2. The size of the airflow can be adjusted by the air nozzle.

[0043] like Figure 1 As shown, the working process of the multi-path longitudinal cutting device for cigarettes provided in this embodiment is as follows:

[0044] After the cigarette is lifted by the feeding mechanism 4, it falls down along the gap between the first cigarette drop plate 5 and the second cigarette drop plate 6. The motor drives the transmission wheel 10 to rotate clockwise through the synchronous belt, thereby driving the conveyor belt 1 to move horizontally to the right continuously. At this time, the single cigarette falls into the strip groove of the conveyor belt, and the remaining cigarettes fall into the strip groove behind them in turn under the obstruction of the brush at the bottom of the second cigarette drop plate 6, and move together with the conveyor belt 1.

[0045] When the detection sensor 12 at position A detects the third cigarette, the conveyor belt 1 stops, the corresponding blowing nozzle opens, and the cigarette is blown through the corresponding cigarette delivery pipe 21 into the longitudinal cutter 2 at position A for cutting. After that, the cigarette is blown once every two cigarettes.

[0046] When the detection sensor 12 at position B detects the second cigarette, the conveyor belt 1 stops, the corresponding blowing nozzle opens, and while the cigarette is being blown at position A, it is blown through the corresponding cigarette delivery pipe 21 into the longitudinal cutter 2 at position B for cutting. Then, the cigarette is blown once for every other cigarette.

[0047] When the detection sensor 12 at position C detects the first cigarette, the conveyor belt 1 stops. At the same time as the cigarette is being blown at position A, the corresponding air nozzle also opens, blowing the cigarette through the corresponding cigarette delivery pipe 21 into the slicing machine 2 at position C for slicing. Each subsequent cigarette is blown in the same way. In this way, the three slicing machines 2 can slice the cigarettes at the same time, thereby improving the slicing efficiency.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
