[0044] Unless otherwise required by the content, throughout the following description, the word “including” and its variations, such as “comprising” and “having”, will be interpreted in an open-ended, inclusive sense, that is, as “including but not limited to”.

[0045] In this application, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figures 1 to 12 As shown, the blade cleaning device of this application embodiment includes: a cleaning device body 2; a blade 3, which is rotatably disposed relative to the cleaning device body 2; and a scraper assembly 1, including a scraper 11 and an elastic mounting mechanism 12. The scraper 11 is connected to the cleaning device body 2 through the elastic mounting mechanism 12, and the elastic mounting mechanism 12 is configured to make the cutting edge of the scraper 11 fit against the blade surface of the blade 3 and the pressure of the cutting edge on the blade surface is adjustable.

[0048] By configuring the scraper assembly 1 and connecting the scraper 11 to the cleaning device body 2 using the flexible mounting mechanism 12, the cutting edge of the scraper 11 can always be in contact with the blade surface of the cutter 3 under the action of the flexible mounting mechanism 12. This facilitates the scraper 11 to continuously and effectively remove the accumulated dirt from the surface of the cutter 3, thereby improving the cutting quality of the cutter 3 and extending its service life. Furthermore, when the cutter 3 vibrates during operation, the flexible mounting mechanism 12 can adaptively adjust the pressure of the scraper 11's cutting edge on the blade surface of the cutter 3, ensuring that the scraper 11 maintains reliable contact with the blade surface even under complex working conditions, thus improving the reliability of the cutter dirt cleaning device.

[0049] like Figures 1 to 6 As shown, in some embodiments of the blade cleaning device, the blade cleaning device includes two scraper assemblies 1, and the cutting edges of the scrapers 11 of the two scraper assemblies 1 are respectively attached to the two blade surfaces of the blade 3.

[0050] By setting two scraper assemblies 1 and making the scraper 11 blades of the two scraper assemblies 1 respectively fit into the two blade surfaces of the cutter 3, it is convenient to clean the dirt on the two blade surfaces of the cutter 3 at the same time, thereby improving the cleaning effect of the cutter dirt cleaning device.

[0051] like Figure 8 As shown, in some embodiments of the blade cleaning device, the resilient mounting mechanism 12 includes: a spring 122 configured to apply a force toward the blade surface to the scraper 11; and a spring force adjustment mechanism configured to adjust the spring force of the spring 122.

[0052] By setting up spring 122 and spring force adjustment mechanism, the spring force of spring 122 can be adjusted according to the state of dirt accumulation and the wear of cutter 3, thereby facilitating the adjustment of the pressure of the scraper 11 blade on the cutter 3 blade surface.

[0053] like Figures 8 to 9 As shown, in some embodiments of the blade cleaning device, the elastic adjustment mechanism includes: a guide sleeve 123, including a through guide sleeve hole 1231, the through guide sleeve hole 1231 including an internal thread; an adjusting screw 121, which engages with the internal thread; a sliding sleeve 125, the sliding sleeve 125 being movably disposed in the guide sleeve hole 1231 along the axial direction of the blade 3, the scraper 11 being mounted on the sliding sleeve 125, and a spring 122 being disposed between the adjusting screw 121 and the sliding sleeve 125.

[0054] The arrangement of the guide sleeve 123, adjusting screw 121, sliding sleeve 125, spring 122, and scraper 11 allows for adjustment of the spring force of spring 122, thereby adjusting the pressure of the scraper 11's cutting edge on the cutting surface of the cutter 3. The guide sleeve 123, with its internal guide sleeve through hole 1231, has an internal thread that engages with the adjusting screw 121 and slides along the sliding sleeve 125, allowing the sliding sleeve 125 to move in a predetermined direction. The scraper 11 is mounted on the sliding sleeve 125, enabling it to move synchronously with the sliding sleeve 125. This ensures that even after wear, the scraper 11's cutting edge remains in contact with the cutting surface of the cutter 3, extending its service life. In addition, the design of the guide sleeve 123 facilitates a compact fit between the adjusting screw 121, the sliding sleeve 125, and the spring 122.

[0055] like Figures 8 to 9 As shown, in some embodiments of the cutter cleaning device, the adjusting screw 121 includes: an operating part 1212 located at the end of the adjusting screw 121 away from the spring 122, configured to operate the adjusting screw 121; and / or a blind hole 1211 located at the end of the adjusting screw 121 close to the spring 122, the spring 122 being partially disposed within the blind hole 1211.

[0056] An operating part 1212 (such as a slotted, Phillips, or hexagonal slot) is provided at the end of the adjusting screw 121 away from the spring 122 to facilitate operation of the adjusting screw 121 to adjust the elastic force of the spring 122. A blind hole 1211 is provided at the end of the adjusting screw 121 near the spring 122, and the spring 122 is partially disposed within the blind hole 1211, which helps to limit the radial displacement of the spring 122 during compression, thereby improving the stability and reliability of the elastic mounting mechanism 12.

[0057] like Figure 8 As shown, in some embodiments of the blade cleaning device, the sliding sleeve 125 includes: a tubular body 1251, a spring 122 partially disposed in the hollow portion of the tubular body 1251; and a mounting ear 1252 disposed on the side of the tubular body 1251 near the blade 3, with the scraper 11 mounted on the mounting ear 1252.

[0058] The sliding sleeve 125 adopts a structure of tubular body 1251 and mounting ear 1252. The hollow part is used to accommodate part of the spring 122, which helps to limit the radial displacement of the spring 122 during compression. The mounting ear 1252 is located on the side of the tubular body 1251 near the cutter 3, providing a reliable and easy mounting position for the scraper 11, so that the scraper 11 can move synchronously with the movement of the sliding sleeve 125.

[0059] like Figure 8 As shown, in some embodiments of the blade cleaning device, the guide sleeve through hole 1231 is arranged along the axial direction of the blade 3.

[0060] By setting the guide sleeve through hole 1231 along the axis of the cutter 3, the sliding sleeve 125 can slide along the axis of the cutter 3, thereby driving the scraper 11 to move along the axis of the cutter 3.

[0061] like Figure 8 As shown, in some embodiments of the cutter cleaning device, the resilient mounting mechanism 12 further includes a limiting structure configured to limit the extreme position of the sliding sleeve 125 relative to the guide sleeve 123 toward the cutter 3.

[0062] By setting a limiting structure, it is beneficial to limit the extreme position of the sliding sleeve 125 relative to the guide sleeve 123 towards the cutter 3, to ensure that the scraper 11 always maintains a reasonable range of movement within the working stroke, to prevent the scraper 11 from overextending and colliding with the cutter 3, and to improve the reliability of the cutter descaling cleaning device.

[0063] like Figure 8 As shown, in some embodiments of the blade cleaning device, the limiting structure includes a limiting block 126, which is fixed to the end face of the guide sleeve 123 near the blade 3, and the sliding sleeve 125 includes a limiting surface 1253 that abuts against the limiting block 126.

[0064] The limiting structure adopts the form of a limiting block 126, which is simple in structure, easy to process and install, and can effectively limit the extreme position of the sliding sleeve 125 relative to the guide sleeve 123 towards the cutter 3, preventing the scraper 11 from extending excessively and colliding with the cutter 3.

[0065] like Figure 8 As shown, in some embodiments of the blade cleaning device, the elastic mounting mechanism 12 includes a mounting sleeve 124, which is fixedly connected to the main body 2 of the cleaning device and includes a mounting sleeve through hole 1241. A guide sleeve 123 cooperates with the mounting sleeve through hole 1241 and is fixedly connected to the mounting sleeve 124.

[0066] By setting the installation sleeve 124, it is easy to achieve a reliable connection between the guide sleeve 123 and the main body 2 of the cleaning device, which facilitates the installation and replacement of the guide sleeve 123 and improves the convenience of maintenance of the flexible installation mechanism 12.

[0067] like Figures 1 to 5As shown, in some embodiments of the blade cleaning device, the cleaning device body 2 includes a fixing seat 21, which is disposed radially outside the rotation axis of the blade 3, and at least one scraper assembly 1 is disposed on the fixing seat 21; and / or the cleaning device body 2 includes a cover 22, which is configured to cover part of the blade 3, and at least one scraper assembly 1 is disposed on the cover 22.

[0068] By setting a fixed base 21, which is located radially outside the rotation axis of the cutter 3, it is ensured that the scraper assembly 1 maintains a stable relative position with the surface of the cutter 3 during the cleaning process. By setting a protective cover 22, on the one hand, it helps to prevent debris and dust generated by the cutter 3 during operation from splashing outward, thus maintaining the cleanliness of the working environment; on the other hand, it helps to prevent accidental contact by operators, thus improving the operational safety of the cutter cleaning device.

[0069] like Figures 11 to 12 As shown, in some embodiments of the blade cleaning device, the cover 22 includes: a cover body 221, including an arc-shaped cover plate 2211 and an arc-shaped flat plate 2212, the arc-shaped flat plate 2212 being connected to one axial end of the arc-shaped cover plate 2211 and the other axial end of the arc-shaped cover plate 2211 being connected to a fixed base 21; a back plate 222, mounted on the arc-shaped flat plate 2212, having a scraper mounting groove 2221, the scraper assembly 1 being mounted in the scraper mounting groove 2221; and a handle 223, mounted at the opening of the arc-shaped flat plate 2212.

[0070] By providing a protective cover body 221 and a back plate 222, the cutter 3 and scraper assembly 1 are protected, preventing debris and dust generated by the cutter 3 during operation from flying outwards. The back plate 222, with a scraper mounting groove 2221, facilitates the installation and precise positioning of the scraper assembly 1. The handle 223 allows operators to quickly open and close the protective cover 22 for operations such as inspecting, maintaining, or replacing the scraper 11.

[0071] like Figures 1 to 6 As shown, in some embodiments of the blade cleaning device, the main body 2 of the cleaning device includes: a hinge 23, a cover 22 connected to a fixing base 21 via the hinge 23, the cover 22 having a closed state covering the end face of the fixing base 21 and part of the blade 3 and an open state exposing the end face of the fixing base 21 and the blade 3; and a locking assembly 24 configured to fix the cover 22 to the fixing base 21 in the closed state.

[0072] By connecting the cover 22 and the fixed base 21 with a hinge 23, the cover 22 can rotate flexibly relative to the fixed base 21, thus quickly switching between a closed state (covering the end face of the fixed base 21 and part of the cutter 3) and an open state (exposing the end face of the fixed base 21 and the cutter 3). The locking assembly 24 securely locks the cover 22 to the fixed base 21 when it is closed, effectively preventing the cover 22 from accidentally opening due to equipment vibration, thereby avoiding the flying of debris generated by the cutter 3 during cutting.

[0073] like Figures 1 to 6 and Figure 10 As shown, in some embodiments of the blade cleaning device, the locking assembly 24 includes: a first base 241 disposed on the fixed base 21; a second base 242 disposed on the cover 22; and a magnet 243 fixedly disposed on one of the first base 241 and the second base 242, and in the closed state, the first base 241 and the second base 242 are connected by the magnet 243.

[0074] The locking assembly 24 consists of a first base 241, a second base 242, and a magnet 243, which facilitates locking and unlocking of the fixed base 21 and the protective cover 22. When the protective cover 22 is closed, the fixed base 21 and the protective cover 22 remain tightly fitted under the action of the magnet 243, thereby preventing the protective cover 22 from being accidentally opened due to equipment vibration or other reasons.

[0075] like Figure 10 As shown, in some embodiments of the blade cleaning device, the connection position of the first base 241 relative to the fixed base 21 is adjustable along the axial direction of the blade 3; and / or the connection position of the second base 242 relative to the cover 22 is adjustable along the axial direction of the blade 3.

[0076] By setting the connection position of the first base 241 relative to the fixed base 21 to be adjustable along the axial direction of the cutter 3; and / or the connection position of the second base 242 relative to the protective cover 22 to be adjustable along the axial direction of the cutter 3, it is beneficial for the first base 241 and / or the second base 242 to be finely adjusted according to the actual position of the protective cover 22 when it is in the closed state, which is beneficial for compensating for assembly deviations caused by deformation of the protective cover 22, thereby improving the adaptability of the locking assembly 24 to different working conditions.

[0077] like Figure 6 As shown, in some embodiments of the blade cleaning device, a blade cooling device 4 is also included. The blade cooling device 4 includes a cooling port 41 and a cooling pipe 42. The cooling pipe 42 is connected to the cooling port 41 and is configured to supply cold air to the cooling port 41. The cooling port 41 is provided on the main body 2 of the cleaning device and is configured to blow cold air to the blade 3 to cool the blade 3.

[0078] By setting up a cutter cooling device 4 including a cooling port 41 and a cooling pipe 42, and by blowing cold air through the cooling pipe 42 to cool the cutter 3, it is beneficial to cool the high-speed rotating cutter 3, which helps to alleviate the melting of glue caused by the heat generated by the cutter 3, and thus facilitates the cleaning of the dirt on the cutter 3.

[0079] like Figure 3 As shown, in some embodiments of the blade cleaning device, a suction device 5 is also included. The suction device 5 includes a suction hole 51 provided on the main body 2 of the cleaning device. The suction hole 51 is configured to collect the dirt cleaned off the blade 3 by the scraper 11.

[0080] By setting up the suction device 5, it is possible to draw the accumulated dirt cleaned from the cutter 3 by the scraper 11 into the suction hole 51 in a timely and efficient manner, thereby effectively preventing the dirt from falling during the cleaning process. This not only helps to maintain the cleanliness of the working environment, but also helps to prevent the dirt from causing secondary pollution to the product.

[0081] The following combination Figures 1 to 12 A more detailed description of a blade cleaning device according to an embodiment of this application will be provided.

[0082] The blade cleaning device includes a main body 2, a blade 3, two scraper assemblies 1, a blade cooling device 4, and a suction device 5.

[0083] The main body 2 of the cleaning device includes a fixed base 21, a protective cover 22, a hinge 23, and a locking assembly 24.

[0084] The fixing seat 21 is mounted on the fixing sleeve radially outside the rotating shaft of the cutter 3 via a threaded connection. A scraper assembly 1 is mounted in a groove on the end face of the fixing seat 21 via a threaded connection. The fixing seat 21 has an annular structure and includes a stepped central cavity that mates with the fixing sleeve and the rotating shaft. The radially outer portion of the fixing seat 21 that mates with the rotating shaft and the cutter 3 is flattened, and the flattened portion is configured to mate with the guide rail (not shown) of the filter cigarette cutting device.

[0085] The cover 22 is configured to cover part of the cutter 3 to form a semi-enclosed space. Another scraper assembly 1 is disposed on the cover 22 at a position corresponding to the scraper assembly 1 on the end face of the mounting base 21. The cover 22 and the mounting base 21 are movably connected by a hinge 23. The cover 22 has a closed state relative to the mounting base 21, covering the end face of the mounting base 21 and part of the cutter 3, and an open state exposing the end face of the mounting base 21 and the cutter 3.

[0086] The protective cover 22 includes a main body 221, a back plate 222, a handle 223, and connecting fasteners. The main body 221 includes an arc-shaped cover plate 2211 and an arc-shaped flat plate 2212. The arc-shaped flat plate 2212 is connected to one axial end of the arc-shaped cover plate 2211, and the other axial end of the arc-shaped cover plate 2211 is connected to a fixed base 21. Connectors for connecting to the hinge 23 are provided on both the inner and outer sides of the arc-shaped cover plate 2211. The side of the connector on the outer side of the arc-shaped cover plate 2211 opposite to the arc-shaped cover plate 2211 has an arc-shaped structure, while the side facing away from the arc-shaped cover plate 2211 is flat. One movable leaf of the hinge 23 is in contact with the flat side of the connector.
