The fixed plate 31 is rotatably connected to one end away from the second mounting plate 19 with two first rotating shafts 32. Each of the first rotating shafts 32 is coaxially connected with a lubrication roller 321.

[0032] In this embodiment, a cylindrical cavity 34 is provided at the bottom of each lubrication box 33 and is connected to the liquid guide groove 36. The two ends of the cavity 34 are rotatably connected to a second rotating shaft 35, and a transport roller 351 is coaxially connected to the second rotating shaft 35. A plurality of transport grooves 352 are provided on the transport roller 351 in a circular array.

Two of the second rotating shafts 35 pass through the lubrication box 33 and the fixed plate 31 and are coaxially connected to the transmission wheel 38. The two transmission wheels 38 on the same side are jointly sleeved with a transmission belt 39. The lubrication roller 321 is provided with a circle of friction layer 322 made of rubber.

[0033] In this embodiment, a sealing ring 231 is provided on the box edge of one of the cleaning boxes 23 on the opening side, and an exhaust hole is opened on the top of one of the cleaning boxes 23. When the two cleaning boxes 23 are closed and filled with water, the exhaust hole is used to maintain the pressure balance inside the cleaning box 23.

[0034] The working process and principle of the present invention are as follows:

[0035] The entire device is installed on the filter rod forming machine, and the main shaft 12 is coaxially arranged with the cutter disc 41. When not in use, the hydraulic cylinder 1 is in a retracted state, which does not affect the normal operation of the cutter 4. When the cutter 4 needs to be cleaned after working for a period of time, the cutter 4 is first stopped and the two blades 42 are allowed to remain in an inclined state, and then the hydraulic cylinder 1 is turned on to push the moving seat 11 forward to make the friction disk 14 fit the cutter disc 41. When the moving seat 11 moves into place, the cleaning mechanism 2 and the lubrication mechanism 3 just move to the rotation path of the blade 42. At this time, the cylinder 27 can be turned on, and the meshing transmission of the second gear 271 and the spur rack 272 is used to make the two cleaning boxes 23 close to each other, so that the rotation gap of the blade 42 is retained between the two cleaning rollers 241.

[0036] After the preparation is completed, the second motor 25 and the first motor 16 are turned on. The two second motors 25 will drive the two cleaning rollers 241 to rotate in the same speed and in the opposite direction. The first motor 16 will drive the main shaft 12 to rotate, and the friction disk 14 will drive the cutter disc 41 to rotate slowly counterclockwise. The blade 42 will follow the rotation of the cutter disc 41 and will first pass through the cleaning mechanism 2. The two sides of the blade 42 will be cleaned by the rotating cleaning roller 241 to remove the adhesive and debris adhered to the surface. The cleaned blade 42 will enter the lubrication mechanism 3. When the blade 42 passes through the lubrication roller 321, the blade surface will contact the roller surface on the lubrication roller 321 and will be coated with lubricant. The first main shaft 32 is driven to rotate by friction with the friction layer 322, and the transport roller 351 is rotated by belt drive. The transport roller 351 transports the lubricating liquid in the lubrication box 33 to the liquid outlet 37 through the transport groove 352 while rotating, so as to replenish the lubricating liquid for the roller surface of the lubricating roller 321, and ensure that the lubricating liquid on the blade 42 is completely coated. During the whole cleaning and lubricating process, there is no need to remove the blade 42. After the cleaning and lubrication is completed, the cutter 4 can continue to work by removing the device, which shortens the cleaning and lubrication time, and also shortens the downtime of the filter rod forming machine, thereby improving the processing efficiency of the filter rods.

[0037] After the two blades 42 have completed cleaning and lubrication, the hydraulic cylinder 1 is turned on again to pull the movable seat 11 back to the initial position, and the cleaning mechanism 2 and the lubricating mechanism 3 will leave the cutter 4. At this time, the cylinder 27 can be started to push the two cleaning boxes 23 closer to each other. During the process of the two cleaning boxes 23 approaching each other, the pressing block 294 will push the push rod 292, and the cleaning liquid in the cylinder 29 will be squeezed into the water supply pipe 26 through the liquid guide pipe 282 by squeezing the piston block 291. After the cleaning box 23 is closed, a relatively closed cleaning chamber will be formed. At this time, the electromagnetic one-way valve in the water supply pipe 26 can be opened to supply water to the cleaning chamber composed of the two cleaning boxes 23. The cleaning liquid will mix with the water flow into the cleaning chamber, and then Then, the second motor 25 is turned on to drive the two cleaning rollers 241 to rotate in the same direction. The roller surfaces of the two cleaning rollers 241 collide and rub against each other in the water with cleaning liquid to achieve self-cleaning. After the self-cleaning is completed, the cylinder 27 is turned on to retract and pull the two cleaning boxes 23 apart, so that the sewage can be discharged automatically. At the same time, after the push rod 292 is not squeezed by the pressure block 294, the piston block 291 will slide back under the action of the second spring 293. Under the action of the one-way valve, the cleaning liquid is extracted from the liquid storage box 28 into the cylinder 29 through the liquid extraction pipe 281, so as to prepare for the next self-cleaning. After each cleaning of the cutter 4, the self-cleaning of the cleaning roller 241 can ensure the cleaning effect of the cutter 4 each time.

[0038] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
