Description

Technical Field

[0001] This invention relates to the field of tobacco production technology, and in particular to a filter rod conveying device and filter rod conveying equipment. Background Technology

[0002] Currently, common filter rod supply equipment mainly consists of two parts: a transmitter and a receiver. In terms of equipment layout, there is a height difference between the transmitter and receiver; specifically, the transmitter is installed higher than the receiver. This height difference is designed for considerations such as overall equipment layout, process flow, and space utilization. However, this height difference also brings a problem: filter rods cannot be directly transported between the two. A special supply bend is needed to connect the transmitter and receiver, allowing the filter rods to be smoothly transferred from the transmitter to the receiver.

[0003] A unique situation arises during the filter cartridge transport process. During production, the filter cartridge may absorb some coffee particles, which are then carried into the supply bend along with the cartridge. However, existing supply bends have a significant design flaw: they are not sealed. This allows coffee particles to easily spill out of the supply bend and fall outside during transport. These spilled particles not only pollute the production environment, increasing the difficulty and workload of cleaning, but may also adversely affect other equipment and components within the workshop, shortening their lifespan.

[0004] More seriously, when coffee particles are scattered inside the supply bend, they tend to accumulate in the bends and narrow sections. Over time, the accumulated coffee particles gradually increase, eventually clogging the supply bend. Once the supply bend is clogged, the delivery of filter rods is hindered, preventing the cigarette machine from receiving filter rods properly, thus affecting the normal operation of the entire cigarette production line. To solve this problem, the only current solution is to periodically stop the machine and assign dedicated personnel to manually clean the supply bend. While this periodic shutdown cleaning method can alleviate the clogging problem to some extent, it also brings a series of negative impacts. Shutting down for cleaning disrupts the continuity of production, leading to wasted production time and reduced equipment utilization and production efficiency. At the same time, manual cleaning also requires a certain amount of labor costs, increasing production costs. Moreover, if cleaning is not timely or thorough, it may cause the clogging problem to recur, further affecting the stability of production and product quality. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to overcome the shortcomings of the related art, and the present invention provides a filter rod conveying device and filter rod conveying equipment.

[0006] This invention provides the following technical solution: A filter rod conveying device includes a conveying body and a cleaning component.

[0007] The conveying body is provided with a conveying bend, the vertical end of which is connected to an inlet connector, and the horizontal end of which is provided with an outlet connector. The conveying body is also provided with a collection section, which is used to collect coffee particles or debris brought by the filter rod passing through the conveying bend. The cleaning component is provided on the conveying body and is used to clean the coffee particles or debris collected by the collection section.

[0008] As a further improvement to the above technical solution, the conveying body is provided with a collection cavity, which is located below the lower side wall of the conveying bend near the discharge joint. The upper end of the collection cavity is provided with a discharge port that communicates with the interior of the conveying bend. The collection cavity is used to form the material collection section.

[0009] As a further improvement to the above technical solution, the cleaning component includes a collection box, which is installed on the discharge connector. The collection chamber is connected to the collection box through a discharge trough. The lower end of the collection box is provided with a ash discharge port, which is connected to a negative pressure device.

[0010] As a further improvement to the above technical solution, multiple conveying bodies are arranged from top to bottom.

[0011] As a further improvement to the above technical solution, the radius of each of the material conveying bends gradually increases from top to bottom, the collection cavity corresponding to the material conveying bend gradually increases from top to bottom, and the discharge port used for communication between the collection cavity and the inside of the material conveying bend gradually increases.

[0012] As a further improvement to the above technical solution, each of the multiple collection cavities is connected to the main collection box through its corresponding discharge trough.

[0013] As a further improvement to the above technical solution, the side of the collection box is provided with an observation port, and a transparent plate is embedded in the observation port.

[0014] As a further improvement to the above technical solution, the end of the collecting cavity away from the discharge trough is connected to a ventilation pipe, and the ventilation pipe away from the opening of the collecting cavity is connected to an air supply device.

[0015] As a further improvement to the above technical solution, a viewing window is provided on the side wall of the material conveying curve, and a transparent plate is embedded in the viewing window.

[0016] The present invention also provides a filter rod conveying device, including a filter rod conveying device as described in any of the above.

[0017] Compared with related technologies, the advantages of this invention are: The filter rod conveying device provided by this invention addresses the issue that, in actual tobacco production scenarios, filter rods need to be moved from the transmitter to the receiver, and this movement typically involves passing through a conveying bend on the conveying body. Since filter rods inevitably carry some coffee particles or debris during the early stages of production and transportation, these impurities become potential factors affecting normal production when the filter rods pass through the conveying bend.

[0018] By installing a collection section at the feed bend, coffee particles or debris carried by the filter rod can be collected. When the filter rod passes through the feed bend, the impurities it carries are intercepted and collected by the collection section, preventing impurities from scattering and accumulating randomly within the feed bend.

[0019] In addition, the cleaning component can clean the collection section periodically or in real time, promptly removing coffee particles and debris collected therein from the outside of the device. Through this cleaning mechanism, the collection section can always remain relatively clean, and its collection efficiency will not be affected by the accumulation of impurities.

[0020] Because the filter rod conveying device of this invention can effectively collect and clean coffee particles and debris carried by the filter rod, it prevents coffee particles from accumulating and clogging in the conveying bend or falling outside, thus ensuring the normal operation of the filter rod conveying process. Throughout the production process, there is no need to stop for cleaning due to blockages in the conveying bend or accumulation of impurities, greatly improving tobacco production efficiency. At the same time, the clean and tidy production environment is beneficial to the health of workers and meets the environmental hygiene requirements of modern industrial production. Furthermore, by reducing the impact of impurities on the filter rod, the final production quality of the filter rod can be ensured, resulting in filter rods that better meet quality standards and providing a strong guarantee for the quality of cigarettes.

[0030] Combination Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a filter rod conveying device, including a conveying body 100 and a cleaning component 200.

[0031] The conveying body 100 is provided with a conveying bend 110. The vertical end of the conveying bend 110 is connected to an inlet connector 120, and the horizontal end of the conveying bend 110 is provided with an outlet connector 130. The conveying body 100 is also provided with a collecting section 140, which is used to collect coffee particles or debris brought by the filter rod passing through the conveying bend 110. The cleaning component 200 is provided on the conveying body 100 and is used to clean the coffee particles or debris collected by the collecting section 140.

[0032] In the actual tobacco production scenario, the filter rod conveying device provided in this embodiment requires the filter rod to be moved from the transmitter to the receiver. This movement typically involves passing through the conveying bend 110 on the conveying body 100. Since the filter rod inevitably carries some coffee particles or debris during the early stages of production and transportation, these impurities become potential factors affecting normal production when the filter rod passes through the conveying bend 110.

[0033] By providing a collection section 140 at the conveying bend 110, coffee particles or debris carried by the filter rod can be collected. When the filter rod passes through the conveying bend 110, the impurities it carries will be intercepted and collected by the collection section 140, preventing the impurities from being scattered and accumulated randomly in the conveying bend 110.

[0034] Furthermore, the cleaning component 200 can periodically or in real-time clean the collection section 140, promptly discharging coffee particles and debris collected in the collection section 140 outside the device. Through this cleaning mechanism, the collection section 140 can always maintain a relatively clean state, and its collection effect will not be affected by the accumulation of impurities.

[0035] Because the filter rod conveying device in this embodiment can effectively collect and clean coffee particles and debris carried by the filter rods, it prevents coffee particles from accumulating and clogging in the conveying bend 110 or falling outside, thus ensuring the normal operation of the filter rod conveying process. Throughout the production process, there is no need to stop for cleaning due to blockage of the conveying bend 110 or accumulation of impurities, greatly improving tobacco production efficiency. At the same time, the clean and tidy production environment is beneficial to the health of workers and meets the environmental hygiene requirements of modern industrial production. Furthermore, by reducing the impact of impurities on the filter rods, the final production quality of the filter rods can be ensured, resulting in filter rods that better meet quality standards and providing a strong guarantee for the quality of cigarettes.

[0036] In some specific embodiments, the conveying body 100 is provided with a collection cavity 141. The collection cavity 141 is located below the lower side wall of the conveying bend 110 near the discharge joint 130. The upper end of the collection cavity 141 is provided with a discharge port communicating with the interior of the conveying bend 110. The collection cavity 141 is used to form the collection part 140. The discharge port is an elongated strip arranged along the conveying direction of the conveying bend 110. The width of the discharge port is smaller than the diameter of the filter rod, so that it can smoothly receive the impurities falling from the conveying bend 110, while preventing the filter rod from accidentally entering the collection cavity 141 during normal conveying. Specifically, during the dynamic process of the filter rod passing through the conveying bend 110, the filter rod will inevitably carry some coffee particles or debris impurities in the early production and transportation stages. As the filter rod moves within the conveying bend 110, the adhesion between these impurities and the filter rod is relatively weak. Under the combined effects of vibration, friction, and gravity generated by the movement of the filter rod, the impurities easily detach from the filter rod. After falling into the conveying bend 110, the detached impurities are subjected to the continuous action of gravity. Since the discharge port of the collection chamber 141 is located below the conveying bend 110, the impurities will slide down the inner wall of the conveying bend 110 under the pull of gravity, and finally fall into the collection chamber 141 from the discharge port.

[0037] The collection chamber 141 is designed to collect any coffee particles or debris that fall into it. As production continues, more and more impurities are collected within the chamber. This centralized collection method offers several advantages. Firstly, it prevents impurities from scattering and accumulating within the feed bend 110, thus preventing blockages in the filter rod conveying channel and ensuring smooth movement of the filter rods within the bend 110 without jamming or clogging due to impurities, which could affect conveying efficiency. Secondly, centralized collection facilitates subsequent unified cleaning and processing of impurities, reducing the difficulty and workload of cleaning, improving the automation and continuity of the entire production process, and thus ensuring the stable and efficient operation of the filter rod conveying process.

[0038] like Figure 3 As shown, in some specific embodiments, the cleaning component 200 includes a collection box 210, which is mounted on the discharge connector 130. This placement of the collection box 210 facilitates connection to the collection chamber 141 and optimizes space utilization, resulting in a more compact overall structure. Furthermore, the relatively regular structure at the discharge connector 130 facilitates the installation and fixation of the collection box 210, ensuring it does not loosen or shift during operation. The collection chamber 141 is connected to the collection box 210 via a discharge chute 150. The lower end of the collection box 210 has a ash discharge port 211, which connects to a negative pressure device. When the negative pressure device starts operating, it creates a negative pressure environment within the collection box 210, which is then transmitted to the collection chamber 141 via the discharge chute 150. Under this negative pressure, the airflow within the collection chamber 141 accelerates, generating a powerful suction force. Under the suction force, coffee granules and other materials are rapidly drawn from the collection chamber 141 through the discharge chute 150 into the collection box 210, and then extracted from the outside of the device through the ash discharge port 211. This negative pressure suction method can quickly and thoroughly clean the materials in the collection chamber 141, greatly improving the cleaning speed. Compared with traditional cleaning methods, negative pressure suction does not require frequent manual cleaning, reducing the workload and labor intensity of manual operation. It also avoids the problem of material accumulation caused by untimely or incomplete manual cleaning, ensuring the continuous and stable operation of the filter rod conveying device and improving the efficiency and quality of the entire tobacco production process.

[0039] In some specific embodiments, multiple conveying bodies 100 are arranged from top to bottom, and the total amount of filter rods that can be conveyed by multiple conveying bodies 100 far exceeds the conveying capacity of a single conveying body 100, which greatly improves the conveying efficiency of filter rods.

[0040] In some specific embodiments, the radius of each conveying bend 110 is not constant, but rather gradually increases from top to bottom. During the filter rod conveying process, the conveying bend 110 plays a crucial role in changing the conveying direction of the filter rods. When the radius of the conveying bend 110 is small, the filter rods turn more sharply within the bend, and their travel path is relatively short. However, as the radius of the conveying bend 110 gradually increases from top to bottom, the turning of the filter rods within the bend becomes relatively gentle, and the travel path also becomes longer.

[0041] The collection chamber 141, corresponding to the conveying bend 110, also gradually increases in size from top to bottom. The collection chamber 141 plays a crucial role in collecting coffee particles and other material impurities within the filter rod conveying device. Because the travel paths of the filter rods differ within conveying bends 110 of varying radii, the amount of impurities shaken off during their journey also varies. Generally, as the radius of the conveying bend 110 gradually increases, the travel path of the filter rod within the bend becomes longer, increasing the number of collisions between the filter rod and the inner wall of the bend. Simultaneously, the vibration generated by the filter rod itself due to the bend intensifies. These factors all contribute to an increase in the amount of coffee particles or other material impurities shaken off the filter rod. Therefore, gradually increasing the size of the collection chamber 141 from top to bottom provides sufficient space to accommodate impurities of varying quantities and distributions, ensuring that impurities can fall smoothly into the collection chamber 141 without overflowing.

[0042] Meanwhile, the size of the discharge port used to connect the collection chamber 141 and the conveying bend 110 also gradually increases from top to bottom. The discharge port is the key channel for impurities to enter the collection chamber 141 from the conveying bend 110, and its size directly affects the collection efficiency of impurities. If the discharge port is too small, when the number of impurities is large, blockage is likely to occur, causing impurities to be unable to enter the collection chamber 141 in time, thus accumulating in the conveying bend 110 and affecting the normal conveying of the filter rod. Setting the discharge port to gradually increase from top to bottom can match the amount of impurities shaken off in the conveying bends 110 of different radii. For conveying bends 110 with a large radius, long filter rod travel path, and a lot of shaken impurities, a larger discharge port can ensure that impurities enter the collection chamber 141 quickly and smoothly; for conveying bends 110 with a small radius, short filter rod travel path, and less shaken impurities, a relatively smaller discharge port can also meet the impurity collection requirements, while also preventing the filter rod from accidentally entering the collection chamber 141 due to an excessively large discharge port.

[0043] Specifically, during the actual filter rod conveying process, as the filter rod passes through each conveying bend 110 sequentially from top to bottom, the radius of the conveying bend 110 gradually increases, and the travel path of the filter rod continuously lengthens. This intensifies the collisions with the inner walls within the bends and the filter rod's own vibration, resulting in a gradual increase in the amount of coffee particles or other material impurities that fall off. At this time, the size of the collection chamber 141 and the discharge port corresponding to the conveying bend 110 also gradually increase accordingly. This corresponding arrangement ensures that all coffee particles or material impurities falling off within each conveying bend 110 are fully collected. The collection chamber 141 has sufficient space to accommodate impurities, and the discharge port ensures that impurities pass smoothly, thereby preventing impurities from accumulating and clogging within the conveying bend 110 or scattering outside the device. This ensures the smooth operation of the filter rod conveying process and improves the effectiveness of the filter rod conveying device in this embodiment.

[0044] In some specific embodiments, the multiple collection chambers 141 are connected to the collection box 210 through their respective discharge troughs 150, which facilitates the negative pressure equipment to synchronously suction the material in each collection chamber 141. Synchronous suction ensures that the material in each collection chamber 141 is cleaned up in the same amount of time, ensuring the continuous and stable operation of the entire filter rod conveying device and improving production efficiency.

[0045] In some specific embodiments, the collection box 210 is provided with an observation port 212 on its side. During the filter rod conveying process, the collection box 210 continuously receives coffee particles and other materials conveyed from each collection chamber 141 through the discharge chute 150. After entering the collection box 210, these materials continue to move towards the ash discharge port 211 under the action of the negative pressure device and are eventually discharged from the device. However, in actual operation, due to the influence of various factors such as the properties of the materials, the flow rate, and the operating status of the equipment, materials may accumulate and block the collection box 210. Once blockage occurs, it will not only affect the cleaning effect, but may also hinder the operation of the entire filter rod conveying device, or even cause equipment failure.

[0046] To facilitate timely detection of blockages within the collection box 210 by operators, a transparent plate is embedded in the observation port 212. The transparent plate possesses good transparency, ensuring operators can clearly see the discharge status inside the collection box 210. Simultaneously, the transparent plate must possess sufficient strength and wear resistance to withstand certain external impacts and friction, ensuring it will not be easily damaged during long-term use. Common materials for transparent plates include acrylic glass, which is not only highly transparent but also lightweight and easy to install.

[0047] During operation, operators only need to periodically or irregularly check the material discharge status within the collection box 210 through the observation port 212. If obstructed material flow, accumulation, or blockage is observed within the collection box 210, appropriate measures can be taken promptly. For example, the operation of the filter rod conveyor can be paused to clean the collection box 210, check the unobstructed flow of the discharge chute 150 and ash discharge port 211, and adjust the parameters of the negative pressure equipment. This method allows for timely elimination of potential malfunctions, ensuring the continuous and stable operation of the filter rod conveyor, and improving production efficiency and product quality.

[0048] Furthermore, the design of the observation port 212 and the transparent panel also provides a certain degree of safety and convenience. The observation port 212 is located on the side of the collection box 210, allowing operators to observe the material without disassembling other parts, making operation convenient and quick. At the same time, the transparent panel and the observation port 212 are typically sealed to prevent material leakage from the observation port 212, ensuring a safe and clean working environment.

[0049] In some specific embodiments, the end of the collecting chamber 141 opposite to the discharge trough 150 is connected to a ventilation pipe 160, which is connected to an air supply device opposite to the opening of the collecting chamber 141. When the air supply device is activated, the airflow generated by the air supply device enters the collecting chamber 141 through the ventilation pipe 160. The airflow forms a strong blowing force in the collecting chamber 141, blowing up coffee particles and other materials in the collecting chamber 141 and sweeping them along the discharge trough 150 towards the collecting box 210. Driven by the airflow, the materials quickly pass through the discharge trough 150 and enter the collecting box 210. After entering the collecting box 210, since the collecting box 210 usually has a certain tilt angle or has a ash discharge port 211 at the bottom, the materials will be discharged from the outside of the device along the tilt surface or directly from the ash discharge port 211 under their own gravity. This cleaning method, which uses air supply equipment for blowing, can quickly and effectively clean the material in the collection chamber 141, preventing the material from accumulating and clogging in the collection chamber 141, and ensuring the normal operation of the filter rod conveying device.

[0050] Furthermore, to improve the efficiency of discharging coffee particles and other materials from the collection chamber 141, the negative pressure device and the air supply device can operate simultaneously. The negative pressure device creates a negative pressure environment within the collection box 210. When the air supply device blows material towards the collection box 210, the negative pressure generated by the negative pressure device creates a strong suction force, which works in conjunction with the blowing force of the air supply device. The air supply device is responsible for blowing material from the collection chamber 141 towards the collection box 210, while the negative pressure device is responsible for quickly sucking the material into the collection box 210 and discharging it from the ash discharge port 211. This combination of positive and negative pressure greatly accelerates the material discharge speed and improves cleaning efficiency.

[0051] In some specific embodiments, a viewing window 111 is provided on the side wall of the conveying bend 110, and a transparent plate is embedded in the viewing window 111. Operators can easily observe the filter rod conveying situation within the conveying bend 110 using the viewing window 111. During daily production, operators only need to periodically or irregularly check the flow status of the filter rods within the conveying bend 110 through the viewing window 111. If it is found that the filter rods are not flowing smoothly within the conveying bend 110, or if there is accumulation or jamming, it can be preliminarily determined that there may be a blockage. At this time, operators can take corresponding measures in a timely manner, such as stopping the operation of the filter rod conveying device, cleaning the conveying bend 110, and checking for foreign objects blocking the flow or quality problems with the filter rods themselves. In this way, blockage problems within the conveying bend 110 can be detected and resolved in a timely manner, preventing further escalation of the fault and ensuring the normal operation of the filter rod conveying device.

[0052] Furthermore, the design of the viewing window 111 also offers a degree of safety and convenience. Operators can observe the interior of the conveyor bend 110 without disassembling any components; observation can be completed simply through the viewing window 111. This not only saves time and effort but also reduces the risk of safety accidents that may arise from disassembling parts. Simultaneously, the sealing design between the transparent plate and the viewing window 111 prevents dust and other impurities generated during the filter rod conveying process from leaking out through the viewing window 111, ensuring a clean and safe working environment.
