Description

Technical Field

[0001] This invention belongs to the field of tobacco machinery technology, specifically relating to a collaborative cooling and cleaning system and method for a circular cutter in a filter tip assembly machine. Background Technology

[0002] In the production process of a filter tipping machine, the double-length cigarette packs wrapped in tipping paper need to be finally cut by a set of high-speed rotating circular cutters to form individual filter cigarettes. During the cutting process, the blade and sides of the circular cutter continuously contact and scrape the adhesive area of ​​the cigarette tipping paper, causing molten adhesive to inevitably adhere to the blade surface. This adhesive solidifies and accumulates in a very short time, forming hard adhesive residue. The continuous accumulation of this residue coats and dulls the cutting edge of the circular cutter, resulting in a significant decrease in its cutting force, which directly causes quality defects such as roughness or beveled cuts on the filter tip end face. At the same time, the increased cutting resistance also exacerbates the abnormal load on the equipment, affecting the stability of the production process. Ultimately, in order to maintain basic production quality and equipment condition, frequent shutdowns for manual cleaning or blade replacement are necessary, severely reducing the operating efficiency of the entire production line.

[0003] To address the aforementioned glue residue problem, the most common solution in existing technology is to use a mechanical scraper cleaning device. This device typically consists of a pair of rigid scraper blades with adjustable clamping force symmetrically mounted on both sides of a circular cutter disc. Driven by a spring or screw mechanism, the cutting edges of the scraper blades are continuously pressed against the side surface of the circular cutter, forcibly scraping away the glue residue adhering to its surface through direct metal-to-metal contact and interference as the circular cutter rotates.

[0004] However, this mechanical scraper cleaning solution has a series of inherent defects caused by rigid contact and passive scraping. First, to achieve scraping, the rigid contact between the scraper blade and the circular cutter surface continuously applies unintended and harmful mechanical wear, causing gradual wear on the circular cutter's cutting edge and body. This not only directly leads to a significant reduction in its effective service life, increasing the cost and frequency of tool replacement, but also necessitates the simultaneous disassembly, adjustment, or replacement of the scraper when replacing the circular cutter, further increasing operational complexity and maintenance time. Second, as an inevitable result of rigid contact and high-speed relative motion, a large amount of frictional heat is generated between the metal scraper and the circular cutter. This heat accumulates locally at the cutting edge, easily causing thermal softening or deformation of the end face material of the cut filter rod (especially temperature-sensitive cellulose acetate or composite material filters), subsequently leading to process defects such as burrs, trailing, and even bevels on the cut, ultimately affecting the uniformity and stability of the final cigarette product's cutting quality.

[0005] This application is submitted to address the aforementioned issues. Summary of the Invention

[0006] To address the problems of worn blades, frictional heat generation, and passive cleaning in existing mechanical scraper cleaning solutions, the present invention aims to provide a synergistic cooling cleaning system and method for circular cutters in filter tip assembly machines. This system can effectively reduce the blade temperature and decrease adhesive adhesion while cleaning the circular cutter, thereby significantly improving the quality of cigarette cutting and extending the blade life.

[0007] The technical solution adopted in this invention is as follows:

[0008] The first aspect of this invention provides a collaborative cooling and cleaning system for the circular cutter of a filter tip assembly machine, the system being installed at the circular cutter 10 of the filter tip assembly machine, comprising:

[0009] The cleaning execution module includes cleaning units 110 disposed opposite to each other on both sides of the circular cutter 10;

[0010] A cooling module, which includes a gas passage unit 210 for providing cooling gas;

[0011] An anti-adhesion module includes an oil mist supply unit 310 for supplying oil mist to the air passage unit 210;

[0012] The cleaning unit 110 includes a seat 111 with an inner cavity 111a and a flexible cleaning component 112 covering the side of the seat 111 facing the circular cutter 10. The working surface of the flexible cleaning component 112 protrudes from the corresponding surface of the seat 111 to contact the circular cutter 10. The air passage unit 210 is connected to the inner cavity 111a. The oil mist supply unit 310 is connected to the air passage unit 210, so that the flowing cooling gas can carry oil mist and deliver it to the inner cavity 111a. Finally, the oil mist acts on the surface of the circular cutter 10 through the flexible cleaning component 112 to jointly complete contact cleaning, blade cooling and surface coating.

[0013] Preferably, the flexible cleaning element 112 is a felt sheet.

[0014] Preferably, the cooling module further includes a vortex tube 220 for generating the cooling gas, and the gas path unit 210 includes a pipe connecting the cold end outlet of the vortex tube 220 to the inner cavity 111a.

[0015] Preferably, the system further includes a control module 401, which is electrically connected to the oil mist supply unit 310 and is used to control the start / stop or oil supply frequency of the oil mist supply unit 310.

[0016] Preferably, the control module 401 includes a programmable logic controller and a time relay for setting time intervals.

[0017] Preferably, the oil agent used in the oil mist supply unit 310 is food-grade paraffin oil. It should be noted that the selection of the oil agent in this invention has been strictly considered. Food-grade paraffin oil is colorless, odorless, chemically stable, and meets food safety standards. In this system, the oil mist, carried by cooling gas and passing through the flexible cleaning element 112, acts only as a very thin film layer on the surface of the circular cutter 10. Its purpose is to change the interfacial characteristics of the metal blade surface to prevent adhesive adhesion, rather than directly contacting the cigarette. Simultaneously, during the subsequent rotary cutting process, the trace amount of oil film on the surface of the circular cutter 10 is further dissipated under the action of cutting friction and airflow, preventing the formation of perceptible residue on the filter tip. This achieves effective protection while ensuring the smoking safety and sensory quality of the final cigarette product.

[0018] Preferably, the cleaning execution module further includes an adjustment mechanism 120, which includes a mounting base 121 and an adjustment screw 122. The mounting base 121 is used to fix the filter nozzle receiving machine frame, and the seat body 111 is connected to one end of the adjustment screw 122. The adjustment screw 122 is threadedly engaged with the mounting base 121, and by rotating the adjustment screw 122, the entire cleaning unit 110 can be driven to move relative to the circular cutter 10.

[0019] A second aspect of the present invention provides a synergistic cooling and cleaning method for a circular cutter of a filter tip assembly machine, employing the synergistic cooling and cleaning system as described in any one of the first aspects, the method comprising the following steps:

[0020] Step S1: Drive the cleaning unit 110 to move by rotating the adjusting screw 122 of the adjusting mechanism 120 so that the flexible cleaning part 112 and the surface of the circular cutter 10 reach a preset relative position or contact pressure.

[0021] Step S2: Incorporate the oil mist into the cooling airflow to form a cooling gas carrying the oil mist, and supply the mixed gas to the inner cavity 111a of the cleaning unit 110;

[0022] Step S3: The mixed gas is passed from the inner cavity 111a through the flexible cleaning member 112 and applied to the surface of the circular cutter 10 to achieve contact cleaning, blade cooling and surface coating simultaneously in one operation.

[0023] Preferably, in step S2, the oil mist is controlled by the control module to be incorporated into the cooling airflow in a timed or intermittent manner.

[0024] Preferably, in step S2, the cooling airflow is generated by compressed air flowing through the vortex tube 220 for cooling.

[0025] The advantages of this invention over the prior art are as follows:

[0026] 1. This invention replaces the scraping action of a rigid metal scraper with the wiping action of a flexible cleaning component (such as felt). This wiping action relies on the soft, porous, and elastic physical properties of the felt itself, allowing it to conform to the surface shape and create a buffer when in contact with the blade surface. This removes adhesive residue while avoiding additional mechanical scratches and wear on the circular cutter body. The integrated cooling gas supply path is connected to the inner cavity of the cleaning unit, allowing cooling gas to pass through the flexible cleaning component and act on the surface of the high-speed rotating circular cutter. Through direct heat exchange, it continuously cools the surface, effectively controlling the temperature of the cutting area and preventing the filter tip material from softening and deforming due to overheating, thus ensuring the physical quality of the cut. Simultaneously, a specific oil mist (food-grade paraffin oil mist) is incorporated into the aforementioned cooling gas through an oil mist supply unit and acts on the blade surface simultaneously, forming an extremely thin protective film during both cleaning and cooling processes. The film layer mainly functions to change the surface properties of the metal to reduce the adhesion of the adhesive, thereby shifting the cleaning and maintenance mode from passive scraping after the fact to proactive prevention, and improving the durability and stability of cleaning performance.

[0027] 2. This invention replaces rigid scrapers with flexible cleaning components (such as felt), avoiding scraping wear on the circular cutter during cleaning. This significantly extends the service life of the circular cutter, directly reducing tool consumption and replacement costs. The modular design and mechanical adjustment mechanism (such as threaded adjusting screws and mounting bases) of the system make the position and pressure adjustment of the cleaning unit simpler and more controllable. During maintenance operations such as tool replacement, there is no need to simultaneously disassemble and adjust the complex scraper assembly, thereby reducing maintenance time, lowering operational complexity, and improving the overall availability and production continuity of the equipment.

[0028] 3. Based on the integrated system already constructed in this invention (the cleaning, cooling, and anti-adhesion modules are physically connected via air paths), the introduction of a control module (PLC and time relay) enables programmed control of the start / stop and operating duration of the oil mist supply unit. This allows the oil mist to be mixed into the continuously supplied cooling airflow at a preset cycle, thus ensuring a timed coordination between the coating process and the cleaning and cooling process in the operational logic. By maintaining this controlled, intermittent coating operation, the system provides a continuous and uniform anti-adhesion interface for the circular cutter surface. The various functional modules thus cooperate under preset logic, jointly forming a composite operating system with manageable operation and more stable results.

[0029] 4. In this invention, the flexible cleaning unit is not merely an independent wiping component, but a composite terminal integrating wiping, media permeation, and support functions. It connects to the airflow unit through the inner cavity of its base, becoming the final interface for the cooling gas and oil mist mixture. This design allows the flexible cleaning component to perform contact wiping while also acting as a permeation layer for uniformly dispersing cooling gas and oil mist, achieving integration of physical cleaning and media delivery functions. More importantly, the three core modules of cleaning, cooling, and anti-adhesion are connected and transported through the shared airflow unit: one end of the airflow unit connects to the air source of the cooling module, then connects to the oil mist supply unit of the anti-adhesion module, and finally leads to the inner cavity of the cleaning unit. This series-connected physical configuration with the airflow as the hub structurally constrains the cooling and anti-adhesion functions to act on the circular cutter's operating path only through the cleaning unit, rather than operating independently. Therefore, the components, through the aforementioned specific connection method, constitute a system with deep functional coupling and a unified operating process.

[0030] 5. Existing technologies, due to their fundamental mechanism of rigid contact and passive scraping, have long suffered from an inherent contradiction: a difficulty in simultaneously achieving effective cleaning, tool protection, and cutting temperature. This invention creatively integrates three distinct physical processes—flexible contact wiping, pneumatic cooling, and oil mist protection—into a single working terminal using a specific series-connected airflow configuration. This not only successfully overcomes the aforementioned contradiction but, more importantly, establishes a mutually beneficial and interdependent relationship between the functional modules: First, the cooling gas continuously acts on the blade surface, its core effect being to reduce the blade's temperature. This prevents the filter material from softening during cutting and creates conditions for subsequent steps: the low temperature makes it easier for splashed adhesive to solidify and set, rather than remaining in a viscous state and spreading. Second, the oil mist, carried by the cooling gas, forms an extremely thin insulating film on the blade surface. This film significantly reduces the actual adhesion between the adhesive and the metal substrate. Under the combined effect of these two factors, even if a small amount of adhesive solidifies and adheres, its structure is more porous and easier to peel off. Finally, the flexible cleaning component wipes the pre-treated blade surface, which improves its effectiveness and durability in removing such weakened adhesive residue, while reducing its own wear.

[0031] Meanwhile, the function of the cooling gas has expanded from simply cooling to acting as a carrier for transporting and forming an anti-adhesion film; while the oil mist, aided by the power of the cooling gas and the uniform diffusion effect of the cleaning components, achieves precise and stable application on the high-speed rotating blade surface. This interlocking functional complementarity and process unification, achieved through the integration of physical configuration and media, solves the problems of wear, temperature rise, and scale regeneration that existing technologies cannot simultaneously overcome, and achieves long-term, synchronous, and stable maintenance of the three key functions of cleaning, cooling, and protection.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figure 1 This embodiment provides a collaborative cooling and cleaning system for the circular cutter of a filter tip assembly machine. The system is installed at the circular cutter 10 of the filter tip assembly machine and is used for online maintenance of the high-speed rotating circular cutter 10 during continuous operation of the equipment.

[0039] The system mainly includes a cleaning execution module, a cooling module, an anti-adhesion module, and a control module 401.

[0040] The cleaning execution module is the execution terminal that directly acts on the circular cutter 10. It mainly includes two cleaning units 110 arranged opposite each other on both sides of the circular cutter 10. Each cleaning unit 110 includes a base 111 and a flexible cleaning element 112. The base 111 is a block structure made of metal or high-strength plastic, with an internal cavity 111a. The flexible cleaning element 112 (preferably an industrial felt sheet in this embodiment) covers and is fixed to the surface of the base 111 facing the circular cutter 10 by mechanical pressing (with a sealing gasket) or by using an oil-resistant adhesive. This installation method ensures a firm connection while relying on the microporous structure of the felt itself as a passageway for gas and oil mist, and uses its overall coverage to achieve edge sealing of the internal cavity 111a, allowing the medium to permeate evenly rather than leak from the periphery. Crucially, the felt working surface of the flexible cleaning component 112 is designed to protrude beyond the corresponding surface of the base 111, ensuring reliable contact wiping between the felt and the side of the rotating circular cutter 10 to remove surface-adhered adhesive residue. Furthermore, the three-dimensional porous structure of the felt allows for media permeation while also absorbing and temporarily storing some oil mist. This not only helps maintain the continuity of the oil film during cooling airflow intervals but also further promotes the uniform distribution of oil mist on the working surface.

[0041] Furthermore, for ease of installation and adjustment, the cleaning execution module also includes an adjustment mechanism 120. Combined with... Figure 2 As shown, the adjustment mechanism 120 includes a mounting base 121 for fixing to the filter nozzle assembly machine frame (not shown in the figure), and an adjustment screw 122 that is threaded into the mounting base 121. One end of the adjustment screw 122 is connected to the back of the seat 111 (e.g., screwed in through a threaded hole or connected through a spherical bearing). When the operator rotates the adjustment screw 122, due to the action of the threaded pair, the entire cleaning unit 110 can be driven to move linearly in a direction perpendicular to the axis of the circular cutter 10, thereby precisely adjusting the contact pressure or gap between the felt sheet and the surface of the circular cutter 10 to adapt to different working conditions.

[0042] The cooling module provides a cryogenic medium, and its core function is to generate and deliver cooling gas. The cooling module includes a vortex tube 220 and an air passage unit 210. The vortex tube 220 (also known as a Rank-Helsch tube) is a widely used and mature existing technology in industrial cooling. Based on the vortex temperature separation effect of compressed air, it achieves gas cooling without moving parts. During operation, its inlet connects to the factory's compressed air network. The compressed air is separated into two streams of different temperatures within the tube, with the lower-temperature stream (cold end outlet) maintaining sufficient delivery pressure. This cooling airflow is delivered through the air passage unit 210 (such as a pipe) to the inner cavity 111a of the aforementioned cleaning unit 110 base 111. Subsequently, the cooling gas, by its own delivery pressure, passes through the porous structure of the flexible cleaning component 112 and directly acts on the working surface of the high-speed rotating circular cutter 10. Through forced convection heat transfer, it continuously removes the heat generated by the cutting friction of the cutter body, thereby effectively cooling the circular cutter.

[0043] The anti-adhesion module provides a medium to prevent adhesive sticking, and its core is the oil mist supply unit 310. The oil mist supply unit 310 (such as an industrial oil mist generator) is connected to the pipe of the gas path unit 210 via a T-connector. The oil mist supply unit 310 stores a specific oil agent (such as the aforementioned food-grade paraffin oil), which utilizes the negative pressure generated by the flowing cooling gas to draw out the oil agent and atomize it into fine particles. When the cooling gas flows through this node, it carries away the generated oil mist, forming a uniform gas-oil two-phase mixture.

[0044] The control module 401 is used to realize automated operation. It includes a programmable logic controller (PLC) and a time relay electrically connected to it. The output terminal of the control module 401 is electrically connected to the solenoid valve or drive motor of the oil mist supply unit 310. By pre-programming in the PLC and setting the parameters of the time relay, the start-stop cycle and single working duration of the oil mist supply unit 310 can be controlled, thereby realizing the timed and intermittent automatic addition of oil mist.

[0045] The connection and coordination of the modules are key to achieving collaborative operation in this invention: the air path unit 210 serves as a shared passage, connecting at one end to the cold end outlet of the vortex tube 220 of the cooling module, then in series with the oil mist supply unit 310 of the anti-adhesion module, and finally leading to the inner cavity 111a of the cleaning unit 110 of the cleaning execution module. This series physical configuration of air source-oil mist access point-acting terminal structurally defines the integration of cooling and anti-adhesion functions, and ultimately acts on the circular cutter 10 through the cleaning unit 110, which is the only outlet. Specifically, after the cooling mixed gas carrying oil mist is delivered to the inner cavity 111a of the base 111, it passes through the porous felt sheet (flexible cleaning element 112) covering its surface under air pressure. In this process, the cooling gas carrying oil mist passes through the interconnected microporous network inside the felt sheet under pressure. The gas directly exchanges heat with the felt and the surface of the circular cutter 10 behind it, achieving rapid cooling. Simultaneously, the oil mist, after passing through the felt, is evenly coated onto the surface of the circular cutter 10 through continuous wiping contact between the felt and the cutter surface, forming an extremely thin and uniform insulating film. Therefore, while performing its physical wiping and cleaning function, the felt also acts as a uniform carrier for the cooling medium and oil mist, achieving a deep coupling and simultaneous execution of the three functions of cleaning, cooling, and film coating.

[0046] Example 2

[0047] This embodiment provides a synergistic cooling and cleaning method applied to the system described in Embodiment 1. This method aims to simultaneously clean, cool, and protect the circular cutter 10 during continuous production at high speed. The method includes the following steps:

[0048] Step S1: Before the system is put into operation or after the circular cutter 10 is replaced, the operator manually rotates the adjusting screw 122 of the adjusting mechanism 120. The linear motion of the screw drives the cleaning unit 110 to move until the flexible cleaning element 112 (felt sheet) and the surface of the circular cutter 10 reach a preset, moderate contact pressure. This step ensures the effectiveness of cleaning and avoids abnormal wear caused by overpressure.

[0049] Step S2: After system startup, the cooling module and anti-adhesion module begin operation. Compressed air is continuously supplied to the vortex tube 220, and the generated low-temperature cooling gas flows through the air path unit 210. Simultaneously, the control module 401 controls the solenoid valve of the oil mist supply unit 310 to periodically open according to preset program logic (e.g., a cycle of 5 seconds on and 55 seconds off via a time relay). When the solenoid valve opens, oil mist is injected into the flowing cooling airflow, forming a mixed medium of cooling gas carrying oil mist. This mixed medium is continuously supplied through a pipe to the inner cavity 111a of the seat 111 of the cleaning unit 110.

[0050] Step S3: With the circular cutter 10 continuously rotating, the mixed medium supplied in step S2 uniformly seeps out from the inner cavity 111a, passes through the flexible cleaning element 112 (felt) covering its outlet, and acts on the high-speed passing surface of the circular cutter 10. This is a synergistic process that achieves multiple effects simultaneously in one operation: First, the low-temperature gas exchanges heat with the high-temperature blade surface, achieving continuous forced cooling of the blade body, effectively controlling the temperature of the cutting area and preventing thermal damage to the filter tip end face; second, the oil mist forms a molecular isolation film on the blade surface, significantly reducing the adhesion of the adhesive to the metal substrate, inhibiting the firm formation of adhesive residue from the source; finally, any loose residue on the cooled and pre-coated blade surface is easily wiped away by the continuously contacting flexible cleaning element 112. The entire process of steps S2 and S3 is continuous and synchronous, thus achieving stable and long-term contact cleaning, blade cooling, and surface coating protection for the circular cutter 10 in a single operation.

[0051] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present invention should be protected by the present invention.
