Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of equipment maintenance and product quality control in the tobacco industry, specifically relating to a tobacco processing equipment, an insect-proof cleaning system, and a cleaning and monitoring method. Background Technology
[0002] In the cigarette production process, the packaging workshop is a crucial step in turning tobacco into finished cigarettes. Packaging equipment has a complex structure, including numerous protective covers, transmission mechanisms, cable trays, and assembly gaps between structural components. During production, fine tobacco fragments and dust inevitably intrude into these hidden corners and hard-to-clean areas inside the equipment.
[0003] Currently, the industry's conventional cleaning method for cigarette packaging equipment mainly relies on operators using compressed air to blow away the surface and visible crevices of the equipment after each production batch. While this cleaning method is simple and quick, it has a significant and inherent drawback: while compressed air blows away surface dust, it also pushes some dust particles into deeper, more difficult-to-reach enclosed spaces within the equipment. These long-accumulated dust particles, rich in nutrients and in a warm, concealed environment, become ideal breeding grounds and breeding grounds for storage pests such as tobacco beetles. Tobacco beetles can complete their entire life cycle—laying eggs, developing larvae, and pupating—within these cleaning dead zones, and their adult insects subsequently spread throughout the workshop, posing a serious pollution threat to the finished cigarettes.
[0004] Once tobacco beetles, their larvae, or eggs are found in finished cigarettes, it will directly lead to a Class A quality incident, causing huge economic losses and damage to the brand reputation of enterprises. Therefore, how to effectively remove accumulated dust in the blind spots of equipment and curb the breeding of tobacco beetles at the source has long been a serious challenge for the tobacco manufacturing industry.
[0005] Existing pest control methods, such as setting up sticky traps and spraying insecticides in workshops, are all passive and reactive measures. Sticky traps can only trap adult insects that have emerged and flown out; they cannot effectively monitor and eliminate hidden sources of pests such as eggs, larvae, and pupae inside the equipment. The use of insecticides must be cautious to avoid secondary pollution of products and the production environment.
[0006] Therefore, there is an urgent need in this field for a technical solution that can proactively and effectively clean the dead corners inside the equipment and simultaneously monitor potential insect infestations at an early stage, in order to make up for the shortcomings of existing technologies and fundamentally improve the quality and safety level of cigarette products. Summary of the Invention
[0007] In order to solve the problem of smoke and dust accumulation in dead corners inside equipment caused by compressed air cleaning methods, and to achieve early monitoring and proactive prevention of pests such as tobacco beetles, this invention provides a tobacco processing equipment, an insect-proof cleaning system, and a cleaning and monitoring method.
[0008] To achieve the above objectives, the present invention employs the following technical solution: An insect-proof cleaning system for tobacco processing equipment, comprising: Suction tubing is installed inside tobacco processing equipment to connect one or more hidden spaces inside the equipment that are difficult to clean. A transparent observation container, the interior of which contains a filter medium, and the upper end of the transparent observation container is provided with an air inlet and an air outlet; the air inlet is connected to the suction pipe network through an air inlet connecting pipe, and the air outlet is connected to a vacuum generator through an air outlet connecting pipe. A vacuum generator is used to evacuate a transparent observation container, creating a negative pressure inside.
[0009] Furthermore, the filter medium is a liquid, and a connecting tube is provided inside the transparent observation container. The upper end of the connecting tube is connected to the air inlet, and the lower end of the connecting tube extends into the filter medium. The transparent observation container is made of a pressure-resistant and transparent material and is used to visually collect and observe impurities drawn out from the hidden space inside the device through the suction pipe network.
[0010] Furthermore, the filter medium is water or a liquid solution containing insecticidal / insect-repellent ingredients.
[0011] Furthermore, the suction network includes multiple branches, which converge into the main pipeline in parallel, and the air intake connection pipe is connected to the main pipeline.
[0012] Furthermore, the air inlet connecting pipe is connected to the air inlet, and the air outlet connecting pipe is connected to the air outlet via quick-connect couplings.
[0013] Furthermore, the interior of the transparent observation container is provided with one or more of a sieve plate, a baffle plate, and a bubble stone to enhance gas-liquid mixing and impurity filtration.
[0014] Furthermore, the vacuum generating device is an industrial vacuum cleaner, and a safety filter is provided between it and the air outlet of the transparent observation container to prevent liquid from being sucked in.
[0015] Furthermore, a suction nozzle is provided at the end of the branch.
[0016] A tobacco processing device that integrates the aforementioned insect-proof and cleaning system.
[0017] A cleaning and monitoring method includes the following steps: S1: Install the suction network inside the tobacco processing equipment, put the filter medium in the transparent observation container, and connect the vacuum generator, the transparent observation container and the suction network. S2: Start the vacuum generator. Impurities in the hidden space inside the tobacco processing equipment are sucked into the suction pipe network and enter the transparent observation container with the airflow, where they are captured by the filter medium. S3: During or after the cleaning process, observe the morphology of the captured impurities through a transparent observation container to determine whether tobacco beetles, tobacco eggs, or tobacco larvae are present.
[0018] Compared with the prior art, the present invention has the following advantages: Source control, thorough cleaning: This invention transforms "blowing dust" into "vacuuming dust," fundamentally avoiding the problem of compressed air pushing smoke and dust into deeper, more inaccessible areas. It proactively and effectively removes accumulated smoke and dust that traditional methods cannot reach, eradicating the breeding environment of tobacco beetles at its source and achieving thorough cleaning. Proactive monitoring and early warning: This invention upgrades the cleaning process into a pest monitoring method. By observing the extracted impurities, it achieves "visualized" early detection of pest activity in hidden areas inside the equipment. This monitoring is much earlier than finding insects in sticky traps or finished products, giving companies valuable time to take targeted measures and realizing a shift from passive remediation to proactive prevention. Integrated design, saving labor and effort: This invention integrates deep cleaning and pest monitoring functions into a simple system, eliminating the need for frequent disassembly of equipment, greatly reducing labor intensity and time costs, and making deep cleaning and monitoring work routine and systematic, which is easy to form a long-term management mechanism.
[0019] Simple structure and low modification cost: The core of this invention is a suction pipe network and a transparent observation container. The structure is simple and reliable, easy to modify and install on existing equipment, and also easy to integrate into new equipment. Compared to potential losses from quality accidents, the investment cost is extremely low, making it highly practical and worthy of widespread adoption. Attached Figure Description

An air inlet connection pipe 3 connects to the main pipeline 8. Known dust-prone areas within the packaging unit include the base area of the main drive housing and the interlayer between its sidewall and the protective plate; the area below the wind-driven filament polishing system and the leveling device, and the area of the wire groove; and the gap area below the cutter head and the waste smoke conveying channel. In these locations, holes of appropriate diameter are drilled, and food-grade oil-resistant silicone tubing with an inner diameter of 8 mm is inserted as branch lines 7. A transparent observation container 1 contains a filter medium 2 inside. The upper end of the transparent observation container 1 has an air inlet and an air outlet. The air inlet is connected to the suction pipe network via an air inlet connecting pipe 3, and the air outlet is connected to a vacuum generator 5 via an air outlet connecting pipe 4. The air inlet connecting pipe 3 and the air inlet, and the air outlet connecting pipe 4 and the air outlet, are connected via quick-connect couplings. The transparent observation container 1 is internally equipped with one or more of a sieve plate, a baffle plate, and an air bubble stone to enhance gas-liquid mixing and impurity filtration. Vacuum generating device 5 is used to evacuate the transparent observation container 1 to create a negative pressure state inside it. The vacuum generating device 5 is an industrial vacuum cleaner, and a safety filter device to prevent liquid from being sucked in is provided between it and the air outlet of the transparent observation container 1.
[0023] The filter medium 2 is water or a liquid solution containing insecticidal / insect repellent ingredients. A connecting pipe 6 is provided inside the transparent observation container 1. The upper end of the connecting pipe 6 is connected to the air inlet, and the lower end of the connecting pipe 6 extends into the filter medium 2.

[0025] A cleaning and monitoring method includes the following steps: S1: Install the suction network inside the tobacco processing equipment 9, put the filter medium 2 into the transparent observation container 1, and connect the vacuum generator 5, the transparent observation container 1 and the suction network. S2: Start the vacuum generator 5. Impurities in the hidden space inside the tobacco processing equipment 9 are sucked into the suction pipe network and enter the transparent observation container 1 with the airflow, where they are captured by the filter medium 2. S3: During or after the cleaning process, observe the morphology of the captured impurities through the transparent observation container 1 to determine whether tobacco beetles, tobacco insect eggs, or tobacco larvae are present. Example 2
[0026] For rigid box packaging units, branch lines 7 can be laid out at several key points, such as the space below the label paper conveying channel and the gap behind the inner frame paper cutter, which can eventually converge to different main pipelines 8, located at both ends of the equipment. During cleaning, a set of mobile cleaning units (including an observation container and a vacuum cleaner) can be used to sequentially vacuum the two main pipelines 8, or an observation container with dual inlets can be used for simultaneous operation.
