Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a waste smoke treatment tool, specifically a waste smoke conveying device for cigarette machines. Background Technology

[0002] Cigarette rolling machines are one of the key pieces of equipment in the cigarette production process. Their main function is to process materials such as tobacco, filters, and cigarette paper into finished cigarettes. During cigarette production, waste smoke and waste materials are inevitably generated. If these wastes are not treated promptly and effectively, they will not only affect the cleanliness of the production environment and the normal operation of the machines, but may also lead to environmental pollution and resource waste.

[0003] Existing methods for handling waste smoke rely on manual intervention, requiring staff to regularly clean and collect it. This not only consumes significant manpower and time but can also negatively impact production efficiency due to untimely processing. Therefore, achieving automated conveying and efficient treatment of waste smoke has become a crucial issue for improving the automation level and environmental benefits of cigarette production lines.

[0004] Patent document CN219340721U discloses a "PROTOS-M5 cigarette machine waste smoke conveying device," which includes a conveyor frame, an electric roller, a driven roller, and a bearing seat. The end of the electric roller is mounted on the side plate at the front end of the conveyor frame, and the driven roller is mounted on the side plate at the rear end of the conveyor frame via the bearing seat. A conveyor belt is sleeved between the electric roller and the driven roller. The above device improves the sealing performance between the shaft head and the end cover by setting a sealing structure at the end of the electric roller, preventing oil inside the roller from seeping out to the outside. It also prevents tobacco shreds, cigarette paper scraps, and other tobacco residues from entering the inside of the roller, reducing the probability of the bearings or motor being contaminated by cigarette ash. However, the device has a complex structure, is difficult to maintain, and tobacco shreds and cigarette paper scraps stuck in the gaps are difficult to clean.

[0005] In summary, waste smoke conveying methods largely rely on manual operation, resulting in low efficiency and frequent manual intervention, which to some extent restricts the automation level and production efficiency of the entire production line. Secondly, waste smoke and waste materials easily fall between the conveying devices during transport, causing equipment wear and increased production line maintenance costs. Due to the lack of effective vibration and collection mechanisms, waste materials are difficult to collect and process centrally, further increasing the risk of environmental pollution and resource waste. Finally, existing waste smoke conveying devices perform poorly in terms of processing efficiency and continuity, failing to meet the high-efficiency and environmentally friendly requirements of modern cigarette production. Summary of the Invention

[0006] This invention addresses the problems of waste smoke and waste materials needing timely removal during current cigarette production processes, and the waste smoke conveying system suffers from high reliance on manual labor, low efficiency, equipment wear due to waste material leakage, pollution risks due to the lack of a collection mechanism, and insufficient processing continuity. It provides a waste smoke conveying device for cigarette machines.

[0007] This utility model is achieved using the following technical solution:

[0008] A waste smoke conveying device for a cigarette machine includes a frame with a feed plate and a discharge plate connected sequentially at its front and rear ends. The frame includes two fixed plates arranged opposite each other. Each fixed plate has a limit block installed at a corresponding position on its top. A smoke-catching groove for accommodating the waste smoke body is provided between two adjacent limit blocks. A connecting plate is provided between the two fixed plates. Cranks rotatably connected to a rotating shaft are installed on both sides of the connecting plate. The cranks on the connecting plate rotate synchronously. The rotating shaft is rotatably mounted on the fixed plate and driven by a servo motor. Support blocks with a central recess are installed at intervals on the connecting plate. When the connecting plate is in a high position, the central recess of the support block is higher than the highest point of the limit block. When the connecting plate is in a low position, the highest point of the support block is lower than the upper surface of the fixed plate. With each rotation of the crank, the connecting plate supports the waste smoke body and moves it to the next smoke-catching groove.

[0009] During implementation, the machine includes a frame, with a feed plate and a discharge plate connected sequentially at the front and rear ends of the frame. The bottom of the frame, feed plate, and discharge plate are all equipped with height-adjustable support feet. The feed plate and discharge plate are arranged at an angle. The discharge plate has a groove at the end facing the frame to accommodate the passage of the connecting plate, which facilitates the movement of the support plate to transport the waste smoke body.

[0010] The frame includes two fixed plates arranged opposite each other. Each fixed plate has a limit block installed at a corresponding position on its top. Between two adjacent limit blocks is a smoke-catching groove to accommodate the waste smoke body. The smoke-catching groove restricts the initial position of the waste smoke body and the target position after each movement, ensuring the accuracy of the conveying.

[0011] Each fixed plate is equipped with a waste trough that slopes towards the waste smoke output end. The waste trough is located directly below both ends of the waste smoke body and is used to collect waste tobacco shreds, cigarette paper scraps, and other tobacco residues that fall off at the end during the waste smoke conveying process. This allows for unified collection and centralized processing, preventing waste from scattering between the frame, fixed plates, and moving parts. This prevents equipment jamming, reduces wear on key moving parts, and greatly facilitates centralized waste collection and processing, reducing disposal costs and environmental risks.

[0012] A connecting plate is provided between two fixed plates. Cranks rotatably connected to shafts are mounted on both sides of the connecting plate. The cranks on the connecting plate rotate synchronously. The shafts are rotatably mounted on the fixed plates and driven by servo motors, which are mounted on the outside of the fixed plates and below the waste trough. Specifically, connecting holes are opened on both sides of the front and rear ends of the connecting plate. A crank is rotatably mounted in each connecting hole, and a shaft is horizontally inserted through the free end of each crank. Each shaft is rotatably mounted on the fixed plate via bearings. One shaft is driven by a servo motor, while the other shafts are driven synchronously by the cranks, maintaining the stable movement of the connecting plate. Alternatively, a transmission device, such as a chain with a sprocket or a belt with a pulley, can be installed on the shafts on the same side as synchronously driven shafts, allowing the two shafts on one side to synchronously drive their respective cranks. The connecting plate is connected to the free ends of the cranks via bearings, converting the circular motion of the cranks into a composite motion of the connecting plate: vertical lifting and horizontal translation (along the waste smoke conveying direction).

[0013] The connecting plate is equipped with recessed support blocks at intervals, each containing a vibrator. If a small electric vibratory motor or electromagnetic vibrator is used, the vibration energy is transferred to the waste smoke itself, breaking down the structure of loose materials such as tobacco shreds and paper. This allows the materials to overcome friction and gravity, falling into the waste trough below. This prevents tobacco residue from falling into the conveying system, thus reducing equipment wear and extending its service life.

[0014] When the connecting plate is in the high position, the middle of the support block is recessed above the highest point of the limit block. When the connecting plate is in the low position, the highest point of the support block is lower than the upper surface of the fixed plate. When the crank rotates one revolution, the connecting plate supports the waste smoke body and moves to the next smoke clamping groove. That is, the support block lifts the waste smoke body at the high point, descends during the forward movement, resets at the low position, and then moves backward back to the starting point, completing one cycle. Each cycle allows the waste smoke to move precisely one station (one smoke clamping groove spacing).

[0015] In use, with the connecting plate in a low position (crank at a specific angle), the highest point of the support block is lower than the upper surface of the fixed plate. The waste smoke body slides into the frame area through the inclined feed plate, falling into the smoke-holding groove formed by the limit blocks on the two fixed plates. At this time, the waste smoke body is completely supported by the limit blocks, and both ends are suspended directly above the waste trough. The servo motor starts, driving the rotating shaft to rotate. The rotating shaft drives the crank on it to make a circular motion. The crank drives the connecting plate to move upward from the low position. As the connecting plate rises, the support block rises accordingly. When the connecting plate moves to the high position, the middle of the support block is recessed above the highest point of the limit block. The waste smoke body is lifted from the bottom by the support block, detached from the support of the limit blocks, and completely supported by the support block. During the lifting process or after the lifting is completed, the vibrator built into the support block vibrates, causing the support block and the waste smoke body on it to vibrate at high frequency. This vibrates the loose waste tobacco shreds, cigarette paper scraps, and other tobacco residue inside the waste smoke body. The waste smoke body is shaken down and falls directly into the waste troughs located directly below both ends of the waste smoke body, achieving centralized collection of waste. The servo motor continues to drive the crank to rotate, and the connecting plate moves forward and downward from the high position. The waste smoke body not only descends but also moves horizontally towards the discharge plate, increasing the distance between the two adjacent smoke-blocking troughs. The crank continues to rotate, and the connecting plate moves to the low position. The highest point of the support block is once again below the upper surface of the fixed plate. The moved waste smoke body falls back into the next smoke-blocking trough in front of it, closer to the discharge plate, and is supported again by the limiting block. Its two ends are suspended above the waste trough. The connecting plate and support block then descend completely below the plane of the fixed plate and no longer contact the waste smoke body. It returns to the initial position and repeats the next cycle. The waste smoke body is gradually conveyed to the smoke-blocking trough at the very end of the frame. The waste smoke body falls onto the inclined discharge plate. Due to the inclination of the discharge plate, the waste smoke body automatically slides out of the device by gravity, completing the conveying process.

[0016] Compared with the prior art, this application has the following advantages:

[0017] This utility model provides a waste smoke conveying device for cigarette machines. Through the design of a servo motor and a rotating mechanism, it realizes the automatic conveying and processing of the waste smoke body, reducing manual intervention and improving work efficiency. At the same time, the vibrator built into the support block can shake the loose waste material inside the waste smoke body into the waste trough for collection when lifting the waste smoke body, avoiding the falling tobacco residue and waste between the conveying devices, thereby reducing equipment wear and extending service life, and solving the problems of equipment jamming and component wear caused by waste scattering. In addition, through repeated lifting, moving and conveying operations, the waste smoke body is continuously processed and conveyed, improving efficiency while collecting waste material centrally into the waste trough for subsequent recycling and processing, significantly reducing solid waste disposal costs, reducing environmental pollution and resource waste.

[0023] The present invention will now be described in conjunction with specific embodiments.

[0024] A waste smoke conveying device for cigarette rolling machines, such as Figures 1-3 As shown: It includes a frame 1, with a feed plate 5 and a discharge plate 7 connected sequentially at the front and rear ends of the frame 1. The bottom of the frame 1, the feed plate 5 and the discharge plate 7 are all equipped with height-adjustable support feet 2. The feed plate 5 and the discharge plate 7 are both arranged at an angle. The discharge plate 7 has a groove 8 at the end facing the frame 1 to accommodate the passage of the connecting plate 12, which facilitates the movement of the support plate to transport the waste smoke body 10.

[0025] The frame 1 includes two fixed plates arranged opposite each other. Each fixed plate has a limit block 3 installed at a corresponding position on its top. A smoke-catching groove is provided between two adjacent limit blocks 3 to accommodate the waste smoke body 10. The smoke-catching groove restricts the initial position of the waste smoke body 10 and the target position after each movement, ensuring the accuracy of the conveying.

[0026] Each fixed plate is equipped with a waste trough 4 that slopes towards the waste smoke output end. The waste trough 4 is located directly below both ends of the waste smoke body 10. It is used to collect waste tobacco shreds, cigarette paper scraps and other tobacco residues that fall off the end during the waste smoke conveying process. This allows for unified collection and centralized processing, preventing waste from scattering between the frame 1, fixed plates and moving parts. This prevents equipment jamming, reduces wear on key moving parts, and greatly facilitates centralized collection and processing of waste, reducing disposal costs and environmental risks.

[0027] A connecting plate 12 is provided between two fixed plates. Cranks 11, rotatably connected to shafts 9, are mounted on both sides of the connecting plate 12. The cranks 11 on the connecting plate 12 rotate synchronously. The shafts 9 are rotatably mounted on the fixed plates and driven by a servo motor 6, which is mounted on the outside of the fixed plates and below the waste trough 4. Specifically, connecting holes 13 are opened on both sides of the front and rear ends of the connecting plate 12. A crank 11 is rotatably mounted on each connecting hole 13. A shaft 9 is horizontally inserted through the free end of each crank 11. Each shaft 9 is rotatably mounted on the fixed plate via bearings. One shaft 9 is driven by the servo motor 6, while the other shafts 9 are driven to rotate synchronously by the cranks 11, maintaining the stable movement of the connecting plate 12. The connecting plate 12 is connected to the free ends of the cranks 11 via bearings, converting the circular motion of the cranks 11 into a composite motion of the connecting plate 12, namely, vertical lifting and horizontal translation (along the waste smoke conveying direction).

[0028] The connecting plate 12 is equipped with recessed support blocks 14 at intervals. Each support block 14 contains a vibrator, such as a small electric vibrating motor or an electromagnetic vibrator. The vibration energy is transmitted to the waste smoke body 10, breaking down the structure of loose materials such as tobacco shreds and paper inside. This causes the materials to overcome friction and gravity, falling into the waste trough 4 below. This prevents the waste smoke residue from falling into the conveying device, thereby reducing equipment wear and extending its service life.

[0029] When the connecting plate 12 is in the high position, the middle recess of the support block 14 is higher than the highest point of the limit block 3. When the connecting plate 12 is in the low position, the highest point of the support block 14 is lower than the upper surface of the fixed plate. When the crank 11 rotates one revolution, the connecting plate 12 supports the waste smoke body 10 and moves it to the next smoke slot. That is, the support block 14 lifts the waste smoke body 10 at the high point, lowers it during the forward movement, resets at the low position, and then moves backward back to the starting point, completing one cycle. Each cycle makes the waste smoke move precisely one station (one smoke slot spacing).

[0030] In use, with the connecting plate 12 in a low position (crank 11 at a specific angle), the highest point of the supporting block 14 is lower than the upper surface of the fixed plate. The waste smoke body 10 slides into the frame 1 area through the inclined feed plate 5, that is, falls into the smoke-trapping groove formed by the limiting blocks 3 on the two fixed plates. At this time, the waste smoke body 10 is completely supported by the limiting blocks 3, and both ends are suspended directly above the waste trough 4. The servo motor 6 starts, driving the rotating shaft 9 to rotate. The rotating shaft 9 drives the crank 11 on it to perform circular motion. The crank 11 drives the connecting plate 12 from the low position. As the connecting plate 12 rises, the supporting block 14 also rises. When the connecting plate 12 reaches its highest position, the middle of the supporting block 14 is recessed above the highest point of the limiting block 3. The waste smoke body 10 is lifted from the bottom by the supporting block 14, detached from the support of the limiting block 3, and completely supported by the supporting block 14. During the lifting process or after the lifting is completed, the vibrator built into the supporting block 14 vibrates, causing the supporting block 14 and the waste smoke body 10 above it to vibrate at high frequency, which dissipates the loose waste tobacco and cigarettes inside the waste smoke body 10. Paper scraps and other tobacco residue are shaken off and fall directly into the waste troughs 4 located directly below both ends of the waste smoke body 10, achieving centralized collection of waste. The servo motor 6 continues to drive the crank 11 to rotate, and the connecting plate 12 moves forward and downward from a high position. The waste smoke body 10 not only descends but also horizontally shifts the distance between two adjacent smoke-blocking grooves towards the discharge plate 7. The crank 11 continues to rotate, and the connecting plate 12 moves to a low position. The highest point of the support block 14 is once again lower than the upper surface of the fixed plate, and the moved waste smoke body 10 falls back into its groove. Ahead, in the next smoke trough near the discharge plate 7, it is again supported by the limiting block 3, with its two ends suspended above the waste trough 4. The connecting plate 12 and the supporting block 14 are completely lowered below the plane of the fixed plate, no longer in contact with the waste smoke body 10, and return to the initial position to repeat the next cycle operation. The waste smoke body 10 is gradually conveyed to the smoke trough at the very end of the frame 1. The waste smoke body 10 falls on the inclined discharge plate 7. Due to the inclination of the discharge plate 7, the waste smoke body 10 slides out of the device automatically by gravity, completing the conveying process.

Moreover, for those skilled in the art, this utility model can have various modifications and alterations. Any modifications, improvements, and equivalent substitutions made within the concept and principles of this utility model should be included within the protection scope of this utility model.
