Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a heated cigarette cutting and conveying device. Background Technology

[0002] The cigarette making and rolling unit is an important piece of equipment in traditional cigarette production. It first rolls cigarettes to double their length, then cuts them into two single-length cigarettes. These single-length cigarettes are then conveyed to the next machine for further processing. A loading / unloading tray buffer conveyor is installed at the discharge point of the unit. The single-length cigarettes flow into this buffer conveyor for buffering before being fed into the packaging machine, thus completing the cigarette rolling and packaging process.

[0003] Heated cigarettes are a new type of cigarette that has emerged in recent years. They are generally around 45mm in length, shorter than traditional cigarettes. While traditional cigarette making machines can produce 45mm long cigarettes through design optimizations, and the loading / unloading tray buffer conveyor between the making / unloading machine and the packaging machine can also transport and store 45mm long cigarettes after improvements, during actual heated cigarette production, the cigarettes are prone to becoming horizontal during the loading / unloading tray buffer conveyor process, thus affecting the overall production efficiency of the making / unloading and packaging line.

[0066] This utility model provides a heated cigarette slitting and conveying device, which is installed between a cigarette making unit and a packaging machine. It is used to receive double-length cigarettes output from the cigarette making unit, slit the double-length cigarettes, and then feed them into the packaging machine. The heated cigarette slitting and conveying device includes a hopper, a feeding wheel, a cutting wheel, a turning wheel assembly, and an output mechanism. The hopper has a receiving cavity and an inlet and an outlet communicating with the receiving cavity. The feeding wheel is located at the outlet and is used to remove double-length cigarettes from the receiving cavity. The cutting wheel is located behind the feeding wheel and is used to slit the double-length cigarettes into single-length cigarettes. The turning wheel assembly is located behind the cutting wheel and is used to turn a line of single-length cigarettes around. The output mechanism is located behind the turning wheel assembly and is used to feed the single-length cigarettes into the packaging machine. By setting up the heated cigarette slitting and conveying equipment, a brand-new manufacturing process can be used to prepare heated cigarettes. This allows the cigarettes prepared by the cigarette-making unit to be directly output as double-length cigarettes. Then, the heated cigarette slitting and conveying equipment is used to slit the double-length cigarettes and send them directly into the packaging machine. This avoids the heated cigarettes from becoming horizontal during the conveying process, thereby improving the overall production efficiency of the equipment.

[0067] Please refer to the following: Figures 1 to 3In one embodiment, a heated cigarette slitting and conveying device 100 is provided, which is mainly used to solve the problem that heated cigarettes are prone to becoming horizontal during the process of being conveyed from the cigarette making unit to the packaging machine.

[0068] The heated cigarette slitting and conveying equipment 100 is located between the cigarette making unit and the packaging machine. It is used to receive double-length cigarettes output from the cigarette making unit, slit the double-length cigarettes, and then send them into the packaging machine. In other words, the heated cigarette slitting and conveying equipment 100 is an intermediate conveying device between the cigarette making unit and the packaging machine. The double-length cigarettes produced by the cigarette making unit are processed by the heated cigarette slitting and conveying equipment 100 and then directly conveyed to the packaging machine.

[0069] The heated cigarette slitting and conveying equipment 100 includes a hopper 10, a picking wheel 20, a cutting wheel 30, a turning wheel assembly 40, and an output mechanism 50. The hopper 10 has a receiving cavity 11 and an inlet 12 and an outlet 13 communicating with the receiving cavity 11. The picking wheel 20 is located at the outlet 13 and is used to remove double-length cigarettes from the receiving cavity 11. The cutting wheel 30 is located behind the picking wheel 20 and is used to cut double-length cigarettes into single-length cigarettes. In this application, "behind" refers to the relative position between two components, specifically with reference to the flow direction of the cigarettes in the overall equipment. That is, if component A is located behind component B, the cigarettes will first flow through component B and then into component A. The turning wheel assembly 40 is located behind the cutting wheel 30 and is used to turn a line of single-length cigarettes around. The output mechanism 50 is located on the rear side of the turning wheel assembly 40 and is used to feed cigarettes of single length into the packaging machine.

[0070] During production, double-length cigarettes are pre-buried in the receiving cavity 11 of the hopper 10. The picking wheel 20 orderly retrieves double-length cigarettes from the receiving cavity 11 and passes them towards the cutting wheel 30. After receiving the double-length cigarettes, the cutting wheel 30 cuts them at the center using the cutter in the cutting device 31, forming two rows of single-length cigarettes. These single-length cigarettes are then passed towards the turning wheel assembly 40. Since the two rows of single-length cigarettes face opposite directions after cutting, they cannot be directly used for packaging. After receiving the two rows of single-length cigarettes, the turning wheel assembly 40 turns one row of single-length cigarettes around, so that all the single-length cigarettes face the same direction before being passed to the output mechanism 50. After receiving the single-length cigarettes, the output mechanism 50 passes them to the packaging machine hopper 200 of the packaging machine.

[0071] The feeding wheel 20 is equipped with several U-shaped material grooves, the width of which is slightly larger than the diameter of a single cigarette stick. Each material groove has a negative pressure hole. After the equipment is started, a negative pressure is generated in the negative pressure hole, thereby adsorbing the cigarette stick into the material groove. As the feeding wheel 20 rotates, the cigarette stick is carried away from the receiving cavity 11 and passed downwards. Other drums in this equipment also pass cigarette sticks in this manner. This is a drum transfer method known in the art and will not be described in detail below. In addition, the functional names of each drum in this equipment represent that the drum has a corresponding structure or that the drum has a corresponding structure on its side. For example, the cutting wheel 30 represents that it has a corresponding cutting structure (i.e., the cutting device 31) at the drum, thereby realizing the cutting function; the turning wheel group 40 represents that it has a corresponding turning structure at the drum, thereby realizing the turning function of a row of cigarette sticks. This is known in the art and will not be described in detail below.

[0072] Understandably, in the production of traditional cigarettes using existing technology, cigarettes of single-length length are first output from a cigarette-making unit to a buffer conveyor on a loading and unloading tray for buffering, and then fed into the packaging machine by the buffer conveyor. This completes the cigarette-making and packaging process. Heated cigarettes, however, are a newer type of cigarette that has emerged in recent years. Since heated cigarettes have a similar structure to traditional cigarettes—both are wound—they can also be produced by modifying traditional cigarette equipment. For example, modifications to traditional cigarette-making units and the buffer conveyor on the loading and unloading tray can also enable the production of heated cigarettes. However, heated cigarettes are generally around 45mm in length, shorter than traditional cigarettes. Although adaptive modifications to traditional cigarette equipment can enable the production of heated cigarettes... However, due to the short length of heated cigarettes, during the process of the cigarette rolling unit outputting heated cigarettes to the loading and unloading tray buffer conveyor, and during the process of the loading and unloading tray buffer conveyor receiving and conveying cigarettes, the cigarettes are very prone to horizontal movement, which can cause the cigarettes to easily become blocked and accumulate in the conveying channel, thus affecting the production efficiency of the entire rolling and packaging line.

[0073] This embodiment provides a heated cigarette slitting and conveying device 100, which improves existing cigarette processing technology and makes it better suited for the production of heated cigarettes. Because the heated cigarette slitting and conveying device 100 has a slitting function, the cigarette rolling and sealing unit can directly output cigarettes of double length. In other words, the installation of the heated cigarette slitting and conveying device 100 changes the previous entire processing flow, allowing the cigarette rolling and sealing unit to output cigarettes of double length instead of single length, approximately 90mm long. This better prevents cigarettes from becoming horizontal during conveying, thus avoiding blockages and accumulation at the end of the rolling and sealing unit, thereby improving the production efficiency of the entire rolling and packaging line. Furthermore, the heated cigarette slitting and conveying device 100 can directly slit and convey double-length cigarettes to the packaging machine's hopper 200, further improving the stability of cigarette conveying and increasing the overall production efficiency of the line.

[0074] Understandably, since the cigarette making unit can directly output heated cigarettes of double length, the length of the cigarettes is similar to that of ordinary cigarettes. Therefore, the cigarettes are transported more stably to the loading / unloading tray buffer conveyor, reducing the likelihood of horizontal movement. Furthermore, if the heated cigarette slitting and conveying equipment 100 is directly connected to the cigarette making unit and packaging machine, the upstream and downstream equipment would form a single integrated unit. If the downstream equipment malfunctions, the upstream cigarette making unit would also be unable to perform production. This situation would significantly impact production efficiency, especially during mass production, and is unacceptable. Preferably, in one embodiment, the heated cigarette slitting and conveying equipment 100 is located behind the loading / unloading tray buffer conveyor to receive the double-length cigarettes fed in by the loading / unloading tray buffer conveyor. That is, in this embodiment, the heated cigarette slitting and conveying equipment 100 indirectly receives the double-length cigarettes output by the cigarette making unit, rather than directly receiving them. The equipment distribution in the entire cigarette making and packaging line is as follows: cigarette making unit – loading and unloading tray buffer conveyor – heated cigarette slitting and conveying equipment 100 – packaging machine. The loading and unloading tray buffer conveyor can buffer the double-length cigarettes produced by the cigarette making unit, allowing for direct disconnection between the upstream and downstream equipment. In the event of a downstream equipment failure, the upstream equipment can continue operating, further ensuring production efficiency. For example, if the downstream packaging machine malfunctions and stops, the cigarette making unit can continue operating (until the loading and unloading tray buffer system is full). Similarly, if the upstream equipment fails, the downstream equipment can also continue operating, further ensuring production efficiency. For example, if the cigarette making unit malfunctions and stops, the loading and unloading tray buffer device can choose to continue supplying material to the heated cigarette slitting and conveying equipment 100, which in turn supplies material to the packaging machine for further packaging.

[0075] Preferably, in one embodiment, the hopper 10 is provided with two discharge ports 13, and two picking wheels 20 are provided, with one picking wheel 20 corresponding to each discharge port 13. A converging wheel 60 is also provided between the picking wheel 20 and the cutting wheel 30, and the cutting wheel 30 is located behind the converging wheel 60. The two picking wheels 20 respectively take out double-length cigarettes from the receiving cavity 11 and pass them towards the converging wheel 60. The converging wheel 60 collects the double-length cigarettes and then sends them to the cutting wheel 30 for uniform cutting. That is to say, in one embodiment, the hopper 10 and the picking wheels 20 are a dual-channel material picking structure, which can simultaneously pick up materials through the two picking wheels 20.

[0076] Understandably, traditional filter tip rolling and forming units have a tip feeding system, which can be divided into four-part cutting and six-part cutting according to user process requirements. Traditional four-part cutting and six-part cutting tip feeding systems are usually single material feeding channel mode, that is, only one feeding wheel takes material from the hopper. As the equipment operating speed gradually increases, the rotation speed of the feeding wheel increases rapidly accordingly. However, the excessively high rotation speed will cause the feeding wheel to squeeze the cigarette during the material feeding process, which can easily cause cigarette damage and result in an excessively high cigarette scrap rate. At the same time, it will also cause the frequency of empty slots at the feeding wheel to be too high, which can easily lead to malfunctions and shutdowns, reducing the overall effective operating rate of the machine.

[0077] Furthermore, in the current heated cigarette production process, one process requires a two-stage cutting process. This process typically uses a cutting and turning device to cut, turn, inspect, and reject cigarettes that are twice the length. However, when the cigarette production speed (finished product output speed) and the size of the feeding rollers are the same (the number of U-shaped feed troughs is the same), the feeding roller speed in the two-stage cutting process is twice as high as that in the four-stage cutting process. This means that the feeding rollers in the two-stage cutting process cause a higher rate of cigarette damage during the feeding process, a higher frequency of empty feed troughs, more downtime due to malfunctions, and a lower overall machine efficiency, which is unacceptable in the production process.

[0078] To address the aforementioned issues, including cigarette damage, high empty slot rate, and high scrap rate caused by single-piece cutting and material handling, as well as the stable conveying of 45mm heated cigarettes, it is necessary to modify the production process. First, by improving the traditional cigarette-making unit, the unit outputs cigarettes of double length (90mm). These double-length cigarettes are then conveyed to the hopper 10. The material-picking wheel 20 picks up these double-length cigarettes, which are then cut into single-length (45mm) cigarettes. After necessary inspection and rejection, the cigarettes are turned around by the turning wheel set 40 to ensure consistent filter orientation. Finally, they are connected to the packaging machine via the output mechanism 50. The heated cigarette cutting and conveying equipment 100 connects upstream to convey 90mm-length cigarettes (standard size) and downstream directly connects to the packaging machine's hopper 200, reducing the need for loading and unloading trays. This solves the problem of 45mm-length heated cigarettes easily becoming horizontal during conveying, thus improving production efficiency.

[0079] Specifically, in one embodiment, the discharge ports 13 are provided on the left and right sides of the bottom of the hopper 10, thereby forming a structure for simultaneous material collection from the left and right sides.

[0080] Specifically, in one embodiment, an acceleration wheel 21 is respectively provided on the rear side of the two feeding wheels 20. The acceleration wheel 21 is mainly used to increase the cigarette conveying speed. One acceleration wheel 21 is directly connected to the converging wheel 60, and the other acceleration wheel 21 is connected to the converging wheel 60 through a transition wheel 22. For example, as Figure 1 As shown, the left-side picking wheel 20 picks up cigarettes and feeds them into the left-side accelerating wheel 21, which then directly feeds them into the converging wheel 60. Conversely, the right-side picking wheel 20 picks up cigarettes and feeds them into the right-side accelerating wheel 21, which then feeds double-length cigarettes into the transition wheel 22, which in turn feeds them into the converging wheel 60. The converging wheel 60 has twice the number of feed slots as the accelerating wheel 21 and the transition wheel 22, allowing the cigarettes from the two accelerating wheels 21 to be combined into a single column for subsequent cutting.

[0081] Preferably, in one embodiment, the bottom of the hopper 10 is further provided with two conveying mechanisms 14, one of which is directed towards one of the discharge ports 13, and the other is directed towards the other discharge port 13. For example, as Figure 1 As shown, the conveying direction of the left-hand conveying mechanism 14 is to the left, and the conveying direction of the right-hand conveying mechanism 14 is to the right. The conveying mechanism 14 helps to better guide the material in the receiving cavity 11 towards the discharge port 13. Specifically, in one embodiment, the conveying mechanism 14 is a belt conveyor. Each of the two picking rollers 20 has a cigarette-dispensing roller 15 on its top. When the picking roller 20 removes cigarettes from the hopper 10, multiple cigarettes may be adsorbed in one trough. The cigarette-dispensing roller 15 is used to displace the excess cigarettes mistakenly adsorbed in the trough of the picking roller 20, preventing the roller from becoming clogged. The conveying mechanism 14 is used to transport the cigarettes at the bottom of the hopper 10 towards the picking roller 20, allowing the cigarettes to circulate within the hopper 10 and preventing them from being squeezed and deformed.

[0082] Preferably, in one embodiment, a barrier 16 is provided in the middle of the hopper 10, which divides the receiving cavity 11 into a first chamber 111 and a second chamber 112. One discharge port 13 is located on the bottom side of the first chamber 111, and the other discharge port 13 is located on the bottom side of the second chamber 112. One conveying mechanism 14 is located at the bottom of the first chamber 111, and the other conveying mechanism 14 is located at the bottom of the second chamber 112. This structure can separate the spaces where the discharge ports 13 are located on both sides, thereby avoiding interference between material flows, improving the stability of the material picking wheel 20, and also better ensuring the orderliness of the material in the hopper 10.

[0083] More preferably, the barrier 16 evenly divides the first chamber 111 and the second chamber 112 in the receiving cavity 11, so that the first chamber 111 and the second chamber 112 have equal volumes and can accommodate the same amount of material, thereby improving the uniformity of material intake.

[0084] More preferably, the top surface of the barrier 16 is an inclined surface 161 that slopes to both sides. When a cigarette of twice the length falls into the barrier 16, the inclined surface 161 can guide the cigarette of twice the length to fall to both sides, making the material fall more smoothly and evenly.

[0085] Preferably, in one embodiment, a separating wheel 70, a detection wheel group 80, and a rejection wheel 90 are further provided between the cutting wheel 30 and the turning wheel group 40. The separating wheel 70 is located behind the cutting wheel 30 and is used to axially separate two single-length cigarettes in the same row. It can be understood that the two rows of single-length cigarettes after being cut by the cutting wheel 30 will be as follows: Figure 3The distribution is shown in a mirror image (i.e., the filter section is on the inside, and the smoke-generating sections are on the outside at both ends). The separating wheel 70 is mainly used to separate the two rows of single-length cigarettes that are tightly attached after cutting by a certain distance, which facilitates subsequent processing and inspection of the cigarette end faces. The detection wheel group 80 is located behind the separating wheel 70 and is used to detect the single-length cigarettes. The rejection wheel 90 is located behind the detection wheel group 80 and is used to reject unqualified cigarettes. The turning wheel group 40 is located behind the rejection wheel 90. The detection wheel group 80 and the rejection wheel 90 together form a detection system used to detect whether the single-length cigarettes after cutting meet the quality standards. Cigarettes that meet the standards continue to be passed on, while unqualified cigarettes are rejected at the rejection wheel 90 by the instantaneous positive pressure in the negative pressure hole. The number and type of detection wheels in the detection wheel group 80 can be selected according to actual detection needs. For example, in one embodiment, the detection wheel assembly 80 includes an end face detection wheel 81 and an HID detection wheel 82. The end face detection wheel 81 is mainly used to detect whether the two ends (filter end and core end) of a single-length cigarette are concave or loose, and whether the tobacco filling is full. The HID detection wheel 82 is mainly used to detect the inhalation assembly of a single-length cigarette, and physical indicators such as ventilation and leakage.

[0086] Preferably, in one embodiment, the turning wheel assembly 40 uses a conical drum wheel for turning the cigarette. Specifically, the turning wheel assembly 40 includes an unloading wheel 41 and a conical drum wheel 42. It is understood that, as Figure 3 As shown, the two rows of qualified single-length cigarettes sent from the rejection wheel 90 are still mirror-image distributed when they reach the discharge wheel 41, and cannot be discharged directly. When the two rows of single-length cigarettes are passed to the discharge wheel 41, one row is passed normally to the rear, while the other row is sent into the conical drum 42. After being turned around by the conical drum 42, it is sent back to the discharge wheel 41, where it merges with one row in the discharge wheel 41, forming a row of single-length cigarettes with the same direction. After the cigarettes have been turned around, they return to the discharge wheel 41 to continue to be passed to the rear.

[0087] Preferably, in one embodiment, an intermediate wheel 101 and a smoke-transfer wheel assembly 102 are further provided between the turning wheel assembly 40 and the output mechanism 50. The intermediate wheel 101 is located behind the turning wheel assembly 40, and the smoke-transfer wheel assembly 102 is located behind the intermediate wheel 101. The drums in the smoke-transfer wheel assembly 102 are arranged sequentially along the height direction. The output mechanism 50 is located behind the smoke-transfer wheel assembly 102. The smoke-transfer wheel assembly 102 is arranged in a nearly vertically upward manner to transfer the single-length cigarettes after cutting and turning upward. The main function of the smoke-transfer wheel assembly 102 is to transfer the material from a low position to a high position, which facilitates the material transportation to the subsequent process flow of the packaging machine, so that the single-length cigarettes can finally dock with the packaging machine's hopper 200.

[0088] It should be noted that the smoke conveyor wheel assembly 102 can be adjusted by increasing or decreasing the number of drums according to the actual height requirements of the downstream packaging machine. For example, in Figure 1 In the illustrated embodiment, the smoke conveyor wheel assembly 102 comprises six drums arranged sequentially along the height direction. Of course, in other embodiments, the number of drums in the smoke conveyor wheel assembly 102 is not limited to this. Figure 1 The quantities listed in the illustrated embodiment are obviously adjustable according to process requirements, with the number of drums in the smoke conveying wheel assembly 102 being adjustable. Furthermore, to ensure the correct direction of the smoke conveying path and the smoke exit direction, the number of drums in the smoke conveying drum assembly 102 must be increased or decreased in pairs.

[0089] Preferably, in one embodiment, the heated cigarette slitting and conveying device 100 further includes a sampling wheel 103. Along the rotation direction of the intermediate wheel 101, the intermediate wheel 101 sequentially has a feeding position 1011, a picking position 1012, and a discharging position 1013. The turning wheel assembly 40 is disposed at the feeding position 1011, the sampling wheel 103 is disposed at the picking position 1012, and the cigarette conveying wheel assembly 102 is disposed at the discharging position 1013. That is, the sampling wheel 103 is located in the area between the feeding and discharging points of the intermediate wheel 101, and the cigarettes in the sampling wheel 103 sequentially flow through the feeding position 1011, the picking position 1012, and the discharging position 1013. When the equipment is operating normally, the intermediate wheel 101 receives a single-length cigarette from the feed position 1011 and, through its own rotation, feeds the single-length cigarette from the discharge position 1013 into the cigarette conveying wheel assembly 102. At this time, the sampling wheel 103 does not need to sample the cigarette. However, when it is necessary to sample and test the quality of the cigarette, the sampling wheel 103 can be activated to collect samples. The sampling wheel 103 is mainly used to check the quality of the finished single-length cigarettes or to check the accuracy of the rejection wheel 90 in rejecting defective cigarettes. For example, through system settings, the sampling wheel 103 can be configured to sample defective cigarettes with a certain appearance quality defect. If the sampled cigarette matches the set defect type, it indicates that the equipment's rejection and sampling systems are accurate, thus verifying the accuracy of the equipment's operation. If the sampled cigarettes are not the desired ones, it indicates inaccurate rejection, meaning the equipment may be mistakenly rejecting qualified cigarettes while failing to reject defective ones, which are then sent to the downstream packaging machine, resulting in a large amount of waste (usually, when the packaging machine detects waste caused by upstream equipment, all cigarettes from a certain period are considered waste). The sampling wheel 103 allows for self-inspection sampling, better ensuring the reliability and accuracy of equipment operation and preventing a large amount of waste during production. The intermediate wheel 101 has two main functions: one is to pass cigarettes to the sampling wheel 103 for sampling, and the other is to pass the remaining cigarettes upwards to the cigarette transfer wheel assembly 102.

[0090] like Figure 1As shown, in a preferred embodiment, the output mechanism 50 includes a smoke-discharging wheel 51, a horizontal conveying channel 52, and a material-dropping device 53. The smoke-discharging wheel 51 is located behind the smoke-transferring wheel assembly 102, and the horizontal conveying channel 52 is located behind the smoke-discharging wheel 51. The material-dropping device 53 is located behind the horizontal conveying channel 52, and its outlet is connected to the packaging machine. The smoke-transferring wheel assembly 102 transmits cigarettes of single-length intensity upwards, then through the smoke-discharging wheel 51 to the horizontal conveying channel 52, which then transmits the cigarettes of single-length intensity horizontally, and finally through the material-dropping device 53 into the packaging machine's hopper 200.

[0091] like Figure 4 As shown, in a preferred embodiment, the output mechanism 50 includes a smoke-discharging wheel 51 and a horizontal conveying wheel assembly 54. The smoke-discharging wheel 51 is located behind the smoke-discharging wheel assembly 102. The horizontal conveying wheel assembly 54 is located behind the smoke-discharging wheel 51, and the drums in the horizontal conveying wheel assembly 54 are arranged sequentially in the horizontal direction. The horizontal conveying wheel assembly 54 is connected to the packaging machine. That is, in this embodiment, the horizontal conveying wheel assembly 54 replaces the horizontal conveying channel for horizontal material transport. The number of drums in the horizontal conveying wheel assembly 54 can be adapted according to the actual position of the downstream packaging machine. Using the horizontal conveying wheel assembly 54 for horizontal transport facilitates connection with packaging machines at various positions, which can be achieved by increasing or decreasing the number of drums.

[0092] The heated cigarette slitting and conveying equipment 100 solves the problem of horizontal movement of heated cigarettes during the conveying process to the packaging machine in existing technologies, thereby improving the overall production line efficiency. Furthermore, the heated cigarette slitting and conveying equipment 100 adopts a dual-channel feeding method. Compared to similar conventional equipment, the feeding wheel speed is significantly reduced at the same production speed, preventing excessive compression and damage to the cigarettes during the feeding process. This effectively reduces the cigarette damage rate, lowers the empty cigarette slot rate, and improves the effective operating rate of the equipment.

[0093] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
