[0033] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a rubbing drum cleaning device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the air-blowing block in a rubbing drum cleaning device provided in an embodiment of this application. The rubbing drum cleaning device provided in an embodiment of this application includes a mounting base 100, a scraper 200, and an air-blowing block 300. The scraper 200 is connected to the mounting base 100 and has a cutting edge 210 for cleaning impurities from the surface of the rubbing drum. The air-blowing block 300 is connected to the scraper 200 and has an air chamber. The chamber wall has an air outlet 310, a first mating hole 320, and a second mating hole 330 communicating with the outside. The first and second mating holes 320 are connected to an air source component, and the air outlet 310 is used to guide the gas in the air chamber toward the cutting edge 210 to clean the scraper 200.

[0034] Specifically, during the operation of the rubbing drum, the rubbing drum rotates relative to the rubbing drum cleaning device, allowing the tip of the scraping edge 210 to scrape against the surface of the rubbing drum, thus removing impurities from the surface. The air blowing block 300 located on one side of the scraper 200 can guide the gas in the air chamber toward the scraping edge 210 through the air outlet 310, thereby cleaning the scraper 200 in a timely manner and preventing impurities scraped off by the scraper 200 from scattering to other locations and causing blockage of the rubbing drum's suction hole and the process groove on the rubbing drum surface. Through the setting of the first mating hole 320 and the second mating hole 330, one of the first mating hole 320 and the second mating hole 330 can be connected to the air source, while the other can be used to observe and clean the air outlet 310, ensuring the reliability of the air outlet 310 and thus improving the cleaning reliability of the rubbing drum cleaning device.

[0035] It should be noted that during normal operation of the rubbing drum cleaning device, one of the first mating hole 320 and the second mating hole 330 can be connected to the air source component, while the other is blocked, so that all the gas in the air chamber is discharged from the air outlet 310. When the cleaning effect of the air blowing block 300 on the scraper 200 is not good, the one of the first mating holes 320 and the second mating hole 330 that is not connected to the air source component can be connected to an auxiliary air source component to check whether the air outlet 310 is blocked or the air source component is malfunctioning. This allows for timely troubleshooting and ensures effective cleaning of the rubbing drum surface.

[0036] See Figure 1 and Figure 2 In one embodiment, the first mating hole 320 is located on the side opposite to the air outlet 310, and the second mating hole 330 is located in the area between the first mating hole 320 and the air outlet 310. That is, the first mating hole 320 and the second mating hole 330 are set in different positions, so that the appropriate installation position can be selected according to different air source components, thereby improving the adaptability of the rubbing drum cleaning device.

[0037] See Figure 1 and Figure 2 In one embodiment, the rubbing drum cleaning device further includes a sealing head. One of the first mating hole 320 and the second mating hole 330 is used to communicate with the air source component. The wall of the other of the first mating hole 320 and the second mating hole 330 is detachably connected to the sealing head, thereby improving the efficiency of detecting the air outlet 310. In this application, the first mating hole 320 or the second mating hole 330 is connected to the air source component via an air pipe connector 340.

[0038] Furthermore, the plug head is threadedly connected to the wall of the first mating hole 320 or the second mating hole 330.

[0039] See Figure 1 and Figure 2 In one embodiment, the air blowing block 300 is provided with a first limiting wall 350, which abuts against the scraper 200. The air outlet 310 is provided on the first limiting wall 350 and is located on the side of the scraper 200 facing the cutting edge 210, so that the airflow blown out through the air outlet 310 is directed to the side of the scraper 200 facing the cutting edge 210, thereby stabilizing the impurities accumulated on the scraper 200 and blowing the impurities off.

[0040] Furthermore, the air-blowing block 300 is located to the side of the scraper 200, that is, the air-blowing block 300 is located on one side of the axial direction of the rubbing drum, so that the impurities accumulated on the scraper 200 can be blown away from the side of the rubbing drum.

[0041] Furthermore, the rubbing drum cleaning device also includes a collection box, which is located on the side of the scraper 200 away from the air block 300, for collecting impurities blown off the scraper 200.

[0042] See Figure 1 and Figure 2 In one embodiment, there are multiple air vents 310, and each air vent 310 is spaced apart. At least two air vents 310 are spaced apart along the extension direction of the cutting edge 210, so as to blow off the impurities accumulated on the cutting edge 210 in time, so as to ensure the cleaning effect of the cutting edge 210 on the surface of the rubbing drum.

[0043] Furthermore, on a plane perpendicular to the axial direction of the rubbing drum, each air outlet 310 is spaced apart in a direction parallel to the extension direction of the scraper 200, thereby ensuring that the gas can be guided to any area of ​​the scraper 200 to avoid the accumulation of impurities on the scraper 200 and improve the cleaning effect of the scraper 200.

[0044] See Figure 1 and Figure 2 In one embodiment, a boss 360 is provided on the first limiting wall 350, and a second limiting wall 370 is provided on the side of the boss 360 facing the scraper 200. The second limiting wall 370 abuts against the scraper 200 to improve the stability of the connection between the air blowing block 300 and the scraper 200.

[0045] Furthermore, the second limiting wall 370 is provided with a locking hole 380. The second limiting wall 370 is attached to the scraper 200 and is connected to the scraper 200 by fasteners such as bolts passing through the locking hole 380.

[0046] See Figure 1 , Figure 2 and Figure 3 , Figure 3This is a schematic diagram of the scraper in a rubbing drum cleaning device provided in one embodiment of this application. In one embodiment, the scraper 200 includes a support section 220 and a scraping section 230. The support section 220 is connected to the mounting base 100. The end of the scraping section 230 is provided with a scraping edge 210, and the side of the scraping section 230 facing the scraping edge 210 is connected to the support section 220 so that the scraping section 230 and the support section 220 are arranged at an angle.

[0047] Specifically, the support section 220 is connected to the side of the scraping section 230 away from the rubbing drum, and the scraping section 230 and the support section 220 are set at an angle. This allows for a reasonable arrangement of the connection position between the support section 220 and the mounting base 100, avoiding interference with the rubbing drum, and also limits the accumulation of impurities on the scraping section 230, preventing them from scattering to other locations under the action of the air force emanating from the air outlet 310, thus improving the reliability of the rubbing drum cleaning device. Furthermore, on a plane perpendicular to the axial direction of the rubbing drum, the air outlets 310 are spaced apart in a direction parallel to the extension direction of the scraping section 230.

[0048] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the scraper 200 is provided with an adjustment hole 240. The rubbing drum cleaning device also includes a fastener, which passes through the adjustment hole 240 and is connected to the mounting base 100. The fastener can move relative to the scraper 200 within the adjustment hole 240 to adjust the gap between the tip of the scraping edge 210 and the surface of the rubbing drum, thereby adjusting the cleaning effect of the scraper 200 on the surface of the rubbing drum and improving the adaptability of the rubbing drum cleaning device. The adjustment hole 240 is located on the support section 220, and the number of adjustment holes 240 is at least two, thereby improving the stability of the connection between the scraper 200 and the mounting base 100.

[0049] Furthermore, in a plane perpendicular to the axial direction of the kneading drum, the adjusting hole 240 extends along the extending direction of the support section 220, and the fastener is slidably connected to the hole wall of the adjusting hole 240 for guidance. Preferably, the fastener is a bolt.

[0050] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 4This is a schematic diagram of the mounting base in a rubbing drum cleaning device according to an embodiment of this application. In one embodiment, the mounting base 100 is provided with a first mounting hole 110 and a second mounting hole 120 spaced apart. The first mounting hole 110 and the second mounting hole 120 are used for the paper guide rail mounting shaft to pass through, so as to fix the mounting base 100 to the paper guide rail mounting shaft. By providing the first mounting hole 110 and the second mounting hole 120, axial rotation of the mounting base 100 relative to the paper guide rail mounting shaft can be avoided, thereby improving the stability of the connection between the mounting base 100 and the paper guide rail mounting shaft.

[0051] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the first mounting hole 110 has a mating groove 130 communicating with the outside on its hole wall. The rubbing drum cleaning device also includes a locking member, which is connected to the mounting base 100 and can press against the groove sidewall of the mating groove 130 to lock the hole wall of the first mounting hole 110 to the paper guide rail mounting shaft.

[0052] Specifically, fastening holes 140 are provided on the sidewalls of the mating groove 130. Locking members pass through the fastening holes 140 and abut against the mounting base 100. The locking members can move relative to the mounting base 100 to push the two sidewalls of the mating groove 130 closer together, thereby reducing the size of the first mounting hole 110 so that the hole wall of the first mounting hole 110 abuts against the paper guide rail mounting shaft, thus connecting the mounting base 100 to the paper guide rail mounting shaft. The first mounting hole 110 is located on the side of the second mounting hole 120 away from the twisting drum.

[0053] In other embodiments, the second mounting hole 120 may also be provided with a mating groove 130 that communicates with the outside, and the hole wall of the second mounting hole 120 may be locked to the paper guide rail mounting shaft by means of a locking member.

[0054] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application also provides a cigarette making machine, including a rubbing drum and the aforementioned rubbing drum cleaning device, the rubbing drum cleaning device being located on one side of the rubbing drum to clean the surface of the rubbing drum. During the operation of the rubbing drum, the rubbing drum rotates relative to the rubbing drum cleaning device, allowing the tip of the scraping edge 210 to scrape against the surface of the rubbing drum, thus removing impurities from the surface. The air blowing block 300 located on one side of the scraper 200 can guide the gas in the air chamber toward the scraping edge 210 through the air outlet 310, thereby cleaning the scraper 200 in a timely manner and preventing impurities scraped off by the scraper 200 from scattering to other locations and causing blockage of the rubbing drum's suction hole and the process groove on the rubbing drum surface. Through the setting of the first mating hole 320 and the second mating hole 330, one of the first mating hole 320 and the second mating hole 330 can be connected to the air source, while the other can be used to observe and clean the air outlet 310, ensuring the reliability of the air outlet 310 and thus improving the cleaning reliability of the rubbing drum cleaning device.
