Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device for a filter rod cutting machine. Background Technology

[0002] With the generational shift in cigarette consumption patterns, personalized products such as slim cigarettes and window cigarettes are becoming increasingly popular. Filter rods (cylindrical components used in cigarette filters, typically made of cellulose acetate tow, latex, glycerides, etc., with some filters wrapped in a plastic film to absorb harmful components in cigarette smoke) are becoming increasingly diverse in material composition. The content of latex, glycerides, and cellulose acetate tow varies, and some filter rods are even wrapped in plastic film. During high-speed cutting, these new materials are prone to accumulating glue residue (residue from melted or adhered material due to frictional heating during cutting, affecting cutting quality) on the cutting seam of the filter cutting wheel and both sides of the cutter. This results in increased cutting resistance, rough cuts, and decreased cigarette quality, severely impacting production efficiency and product consistency.

[0003] Existing cleaning devices are mostly limited to cleaning the cutter blades of the secondary cutting wheel (final cutting wheel), failing to cover the removal of glue residue from the filter tip cutting wheel and the wheel itself. Due to the complex structure of the filter tip cutting wheel, the glue residue accumulated in the cutting seam of the filter tip cutting wheel is difficult to clean, thus increasing the difficulty of subsequent equipment maintenance. Summary of the Invention

[0004] The purpose of this application is to provide a cleaning device for a filter rod cutting machine that can prevent glue residue from adhering to the cutting seam of the filter tip cutting wheel.

[0005] To achieve the above objectives, this application provides a cleaning device for a filter rod cutting machine, comprising: a cutting blade cleaning system and a cleaning ring;

[0006] The blade cleaning system includes a mounting base and a scraper. The mounting base is located next to the blade, and the scraper is mounted on the mounting base and can abut against the blade.

[0007] The cleaning ring includes a first ring plate and a second ring plate. The cleaning ring is sleeved on the filter cutting wheel, and the first ring plate and the second ring plate are respectively attached to the side walls on both sides of the cutting slit of the filter cutting wheel.

[0008] In some embodiments, there are two scrapers, which can abut against the sides of the cutter.

[0009] In some embodiments, the cutter cleaning system further includes an adaptive mechanism that enables the scraper to always be in contact with the cutter.

[0010] In some embodiments, the adaptive mechanism includes a support, a first rotating arm, a second rotating arm, and an elastic element. The support is connected to the mounting base. The first rotating arm and the second rotating arm are both rotatably connected to the support. The two cutters are respectively mounted on the first rotating arm and the second rotating arm and can abut against each other. The two ends of the elastic element are respectively connected to the first rotating arm and the second rotating arm.

[0011] In some embodiments, the blade cleaning system further includes a position adjustment mechanism that can adjust the position of the scraper.

[0012] In some embodiments, the position adjustment mechanism includes a support rod, an adjustment seat, a drive assembly, a threaded rod, and a threaded sleeve. The support rod is disposed next to the cutter, the adjustment seat is mounted on the support rod, the adjustment seat has a through hole, the threaded rod is rotatably fitted in the through hole, the drive assembly is disposed on the adjustment seat and is used to drive the threaded rod to rotate, the threaded sleeve is threadedly fitted to the threaded rod and slidably fitted with the adjustment seat, the mounting seat is disposed on the threaded sleeve, and the threaded sleeve is movable relative to the adjustment seat along its axial direction to move the scraper closer to or away from the cutter.

[0013] In some embodiments, the drive assembly includes a drive wheel, a timing belt, and a driven wheel. The drive wheel and the driven wheel are rotatably fitted onto the adjusting seat. A timing belt is sleeved between the drive wheel and the driven wheel. The driven wheel is connected to the threaded rod. The diameter of the drive wheel is larger than the diameter of the driven wheel.

[0014] In some embodiments, the first ring plate is provided with a first cleaning boss, the second ring plate is provided with a second cleaning boss, the first cleaning boss and the second cleaning boss are symmetrically distributed, and the gap between the first cleaning boss and the second cleaning boss is slightly larger than the thickness of the cutter.

[0015] In some embodiments, both the first cleaning boss and the second cleaning boss are multiple, with the multiple first cleaning bosses distributed at average intervals along the circumference of the first annular piece, and the multiple second cleaning bosses distributed at average intervals along the circumference of the second annular piece.

[0016] In some embodiments, the air distribution wheel body of the filter cutting wheel is provided with cleaning air holes.

[0017] Compared to the aforementioned background technology, the filter rod cutting machine cleaning device provided in this application includes a cutter cleaning system and a cleaning ring. The scraper cleaning device includes a mounting base and a scraper. The mounting base is located next to the cutter, and the scraper is mounted on the mounting base and can abut against the cutter. The cleaning ring includes a first ring plate and a second ring plate. The cleaning ring is sleeved on the filter cutting wheel, and the first and second ring plates respectively abut against the side walls on both sides of the cutting seam of the filter cutting wheel. During normal operation, the cutter maintains high-speed rotation, while the scraper abuts against the cutter and remains stationary.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0032] like Figures 1 to 8 As shown, the filter rod cutting machine cleaning device provided in this application embodiment includes a cutter cleaning system 1 and a cleaning ring 4. The cutter cleaning system 1 includes a mounting base 11 and a scraper 12. The mounting base 11 is located next to the cutter 100, and the scraper 12 is mounted on the mounting base 11 and can abut against the cutter 100. The cleaning ring 4 includes a first ring piece 41 and a second ring piece 42. The cleaning ring 4 is sleeved on the filter cutting wheel 200, and the first ring piece 41 and the second ring piece 42 are respectively attached to the side walls on both sides of the cutting seam of the filter cutting wheel 200.

[0033] Understandably, the cutter 100 rotates at high speed during normal operation, while the scraper 12 abuts against the cutter 100 and remains stationary. The cutter cleaning system 1 cleans the cutter 100 by scraping it with the scraper 12, preventing glue residue from adhering to the side wall of the filter tube. A cleaning ring 4 is installed at the cutting seam of the filter cutting wheel 200, and the cleaning tube can cover the side wall of the filter cutting wheel 200 at the cutting seam to prevent glue residue from adhering to the filter cutting wheel 200. When glue residue needs to be cleaned, only the cleaning ring 4 needs to be replaced, thereby improving the efficiency of later maintenance.

[0034] In some embodiments, there are two scrapers 12, which can abut against the two sides of the cutter 100.

[0035] Specifically, the two scrapers 12 abut against each other, and the ends of the two scrapers 12 near the cutter 100 form a V-shaped groove structure. The two scrapers 12 abut against the two side walls of the cutter 100 respectively. During the rotation of the cutter 100, the two scrapers 12 can simultaneously scrape and clean the two side walls of the cutter 100, thereby improving cleaning efficiency.

[0036] In some embodiments, the cutter cleaning system 1 is further provided with an adaptive mechanism 2, which enables the scraper 12 to always be in contact with the cutter 100.

[0037] It is understandable that by setting the adaptive mechanism 2, the scraper 12 can automatically fit the cutter 100 under the action of the adaptive mechanism 2, thus ensuring a stable cleaning effect.

[0038] like Figures 1 to 3 As shown, based on the above embodiment, the adaptive mechanism 2 includes a support 21, a first rotating arm 22, a second rotating arm 23, and an elastic element 24. The support 21 is connected to the mounting base 11. The first rotating arm 22 and the second rotating arm 23 are both rotatably connected to the support 21. Two cutters 100 are respectively mounted on the first rotating arm 22 and the second rotating arm 23 and can abut against each other. The two ends of the elastic element 24 are respectively connected to the first rotating arm 22 and the second rotating arm 23.

[0039] Specifically, the support 21 is horizontally distributed, with one end fixedly connected to the mounting base 11. Both the first rotating arm 22 and the second rotating arm 23 are L-shaped structures. The first rotating arm 22 has a first support arm and a second support arm, both of which have a free end and a connecting end. The connecting ends of the first and second support arms are interconnected, and a first screw pin is provided at the connection point between the first and second support arms. The first rotating arm 22 is rotatably connected to the support 21 via the first screw pin. The second rotating arm 23 has a third support arm and a fourth support arm, both of which have a free end and a connecting end. The connecting ends are connected to each other. The third and fourth arms are connected by a second screw pin. The second rotating arm 23 is rotatably connected to the support 21 through the second screw pin. The two scrapers 12 are respectively installed at the free ends of the first and third arms. The free ends of the second and fourth arms are provided with spring brackets. The top of the spring bracket is provided with a hanging ring. The elastic element 24 can be a spring. Both ends of the elastic element 24 are provided with hooks. The two hooks are respectively hung on the two hanging rings. The center of the support 21 is also provided with a fixing frame. The fixing frame is fixedly connected to the center of the elastic element 24. The fixing frame is used to fix the elastic element 24.

[0040] It is understandable that the elastic element 24 is always in a stretched state, thereby applying a tightening force to the first rotating arm 22 and the second rotating arm 23. The tightening force can drive the first rotating arm 22 and the second rotating arm 23 to rotate, thereby causing the two scrapers 12 to fit together. When the cutter 100 extends into the mating surface of the two scrapers 12, the two scrapers 12 separate under the push of the cutter 100, and drive the first rotating arm 22 and the second rotating arm 23 to rotate, thereby further stretching the elastic element 24 and increasing the tightening force. The tightening force can apply a pushing force to the two scrapers 12 through the first rotating arm 22 and the second rotating arm 23, thereby causing the two scrapers 12 to fit tightly against the two side walls of the cutter 100.

[0041] In some embodiments, the cutter cleaning system 1 is further provided with a position adjustment mechanism 3, which can adjust the position of the scraper 12.

[0042] Understandably, by setting the position adjustment mechanism 3, the position of the scraper 12 can be adjusted to adapt to different cutters 100 and improve versatility.

[0043] like Figures 1 to 5 As shown, based on the above embodiment, the position adjustment mechanism 3 includes a support rod 31, an adjustment seat 32, a drive assembly 33, a threaded rod 34, and a threaded sleeve 35. The support rod 31 is disposed next to the cutter 100, the adjustment seat 32 is mounted on the support rod 31, the adjustment seat 32 has a through hole, the threaded rod 34 is rotatably fitted in the through hole, the drive assembly 33 is disposed on the adjustment seat 32 and is used to drive the threaded rod 34 to rotate, the threaded sleeve 35 is threadedly fitted to the threaded rod 34, and the threaded sleeve 35 is slidably fitted with the adjustment seat 32, the mounting seat 11 is disposed on the threaded sleeve 35, and the threaded sleeve 35 can move relative to the adjustment seat 32 along its axial direction so that the scraper 12 moves closer to or further away from the cutter 100.

[0044] Understandably, when the position of the scraper 12 needs to be adjusted, the drive assembly 33 drives the threaded rod 34 to rotate relative to the adjusting seat 32. Since the threaded sleeve 35 is threadedly engaged with the threaded rod 34 and the threaded sleeve 35 is limited by the adjusting seat 32, it cannot rotate synchronously with the threaded rod 34. The rotation of the threaded rod 34 can push the threaded sleeve 35 to move axially along the threaded rod 34. The mounting seat 11 is set on the bushing, so that the cutter cleaning system 1 moves synchronously with the threaded sleeve 35 to make the scraper 12 move closer to or further away from the cutter 100. This allows the position of the scraper 12 to be adjusted according to the diameter of the cutter 100, which is suitable for cutters 100 of different diameters.

[0045] In some embodiments, the drive assembly 33 includes a drive wheel 331, a timing belt 333, and a driven wheel 332. Both the drive wheel 331 and the driven wheel 332 are rotatably fitted onto the adjusting seat 32. The timing belt 333 is sleeved between the drive wheel 331 and the driven wheel 332. The driven wheel 332 is connected to the threaded rod 34. The diameter of the drive wheel 331 is larger than the diameter of the driven wheel 332.

[0046] It is understandable that, since the diameter of the drive wheel 331 is larger than that of the driven wheel 332, the linear velocities of the drive wheel 331 and the driven wheel 332 are the same under the action of the synchronous belt 333. Therefore, the angular velocity of the drive wheel 331 is greater than that of the driven wheel 332. By driving the drive wheel 331 to rotate manually or electrically, the displacement of the scraper 12 can be precisely controlled, and the position of the scraper 12 can be precisely adjusted.

[0047] like Figure 7 and Figure 8 As shown, in some embodiments, the first ring plate 41 is provided with a first cleaning boss 43, and the second ring plate 42 is provided with a second cleaning boss 44. The first cleaning boss 43 and the second cleaning boss 44 are symmetrically distributed, and the gap between the first cleaning boss 43 and the second cleaning boss 44 is slightly greater than the thickness of the cutter 100.

[0048] Understandably, when the cutter 100 extends into the cutting slit of the filter cutting wheel 200 and cuts the filter rod, the cutter 100 will extend into the gap between the first cleaning boss 43 and the second cleaning boss 44. The first cleaning boss 43 and the second cleaning boss 44 can perform preliminary cleaning on the cutter 100 to reduce the cleaning burden on the scraper 12. The gap between the first cleaning boss 43 and the second cleaning boss 44 is slightly larger than the thickness of the cutter 100, thereby preventing the cutter 100 from getting stuck. In particular, both the first cleaning boss 43 and the second cleaning boss 44 are provided with notches, which can prevent the cutter 100 from interfering when cutting.

[0049] Based on the above embodiments, there are multiple first cleaning protrusions 43 and multiple second cleaning protrusions 44. The multiple first cleaning protrusions 43 are distributed at average intervals along the circumference of the first annular piece 41, and the multiple second cleaning protrusions 44 are distributed at average intervals along the circumference of the second annular piece 42.

[0050] Specifically, in this embodiment, the first ring plate 41 has nine first cleaning protrusions 43, and the second ring plate 42 has nine second cleaning protrusions 44. Each corresponding first cleaning protrusion 43 and second cleaning protrusion 44 forms a cleaning group, and a cleaning area is formed between two adjacent cleaning groups. The nine cleaning groups divide the cleaning ring 4 into nine cleaning areas. Each cleaning area corresponds to two smoke-collecting grooves on the two filter cutting wheels 200, so as to realize the segmented cleaning of the cutter 100, avoid the generation of cleaning dead corners, reduce the single cleaning burden of the first cleaning protrusions 43 and the second cleaning protrusions 44, and improve the cleaning efficiency.

[0051] In some embodiments, the air distribution wheel body 201 of the filter cutting wheel 200 is provided with cleaning air holes 5.

[0052] Understandably, the negative pressure device carried by the filter rod cutter can draw air from inside the filter cutting wheel 200 through the cleaning air hole 5, so that negative pressure is formed inside the filter cutting wheel 200, and the negative pressure can remove the glue residue attached to the first ring plate 41 and the second ring plate 42.

[0053] In summary, the filter rod cutting machine cleaning device of this application can effectively remove the glue residue in the cutter 100 and the cutting groove, improve the cutting quality of the filter rod, reduce burrs and cutting defects, realize synchronous online cleaning of the cutter 100 and the wheel body during the cleaning process, reduce downtime maintenance time, improve the overall efficiency of the equipment, and combine negative pressure suction with mechanical scraping for more thorough cleaning, reduce the frequency of manual intervention, have a compact structure, are easy to install and maintain, and are easy to modify and upgrade on existing equipment.

[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
