[0033] As Figures 1-6As shown, in the present embodiment, the cleaning device of the accelerating wheel assembly of the filter rod making machine comprises an accelerating wheel assembly and a flow guide ring 9. The accelerating wheel assembly comprises an accelerating wheel inner sleeve 1, an air chamber 2, a rotating shaft 3 and a bearing 4. The rotating shaft 3 is rotationally arranged inside the air chamber 2. The accelerating wheel inner sleeve 1 is sleeved on the rotating shaft 3. In the circumferential direction of the rotating shaft 3, the accelerating wheel inner sleeve 1 and the rotating shaft 3 have a first air chamber 5 therebetween. The bearing 4 is sleeved on the rotating shaft 3. In the length direction of the rotating shaft 3, the bearing 4 and the accelerating wheel inner sleeve 1 have a second air chamber 6 therebetween. The air chamber 2 is provided with a negative pressure passage 7 and an air inlet 8. The two ends of the negative pressure passage 7 are respectively communicated with the first air chamber 5 and an external negative pressure device. The air inlet 8 is communicated with the second air chamber 6. The flow guide ring 9 is sleeved on the rotating shaft 3 and located in the second air chamber 6. The flow guide ring 9 is provided with air holes 10. The second air chamber 6 is communicated with the first air chamber 5 through the air holes 10.

[0034] Specifically, the air chamber 2 has a containing cavity. The accelerating wheel inner sleeve 1, the rotating shaft 3, the flow guide ring 9 and the bearing 4 are all arranged in the containing cavity. In the axial direction of the rotating shaft 3, the accelerating wheel inner sleeve 1, the flow guide ring 9 and the bearing 4 are sequentially arranged on the rotating shaft 3. The outer periphery of the accelerating wheel inner sleeve 1 is fixedly connected with the air chamber 2. The inner periphery of the accelerating wheel inner sleeve 1 is spaced apart from the rotating shaft 3 in the circumferential direction of the accelerating wheel inner sleeve 1 and forms the first air chamber 5. The air chamber 2 is provided with the negative pressure passage 7. The two ends of the negative pressure passage 7 are respectively communicated with the air outlet of the negative pressure device and the first air chamber 5. The inner periphery of the bearing 4 is fixedly sleeved on the rotating shaft 3. The outer ring of the bearing 4 is fixedly connected with the air chamber 2. The second air chamber 6 is arranged between the opening of one end of the accelerating wheel inner sleeve 1 and the bearing 4 and is provided with the flow guide ring 9. The flow guide ring 9 is in clearance fit with the rotating shaft 3. The clearance amount is 0.05 mm. The flow guide ring 9 is communicated with the first air chamber 5 through the air holes 10. The side wall of the air chamber 2 is provided with the air inlet 8. The air inlet 8 is externally connected with a positive pressure air tank and is communicated with the second air chamber 6 where the flow guide ring 9 is located. Under the action of the bearing 4, the rotating shaft 3 rotates relative to the air chamber 2. The flow guide ring 9 and the accelerating wheel inner sleeve 1 are fixedly not moved. The positive pressure air tank introduces the positive pressure gas into the second air chamber 6 through the air inlet 8. The positive pressure gas rapidly fills the second air chamber 6 through the flow guide ring 9. Then, the positive pressure gas in the second air chamber 6 is blown to the first air chamber 5 through the air holes 10. The positive pressure gas disperses and guides the dust and impurities accumulated and remained in the air chamber 2. Finally, the dust and impurities are adsorbed and discharged through the negative pressure passage 7. The dust and impurities accumulated on the accelerating wheel assembly can be cleaned in time. Manual intervention is avoided. Human and material resources are saved. The air chamber 2 can always be kept clean and the stable negative pressure air draft can be maintained in the daily operation process. The service life of the equipment is prolonged. The flow guide ring 9 can more comprehensively clean the dust and impurities remained in the air chamber 2. The frequency of shutdown and disassembly and cleaning caused by the blockage of the accelerating wheel assembly in the production process can be effectively reduced. The failure rate of the equipment can be reduced. The reliability and stability of the equipment can be improved.

[0035] Further, with reference to the drawings Figures 1-6The guide ring 9 includes a middle part 11, a guide part 12, and a sealing part 13. The middle part 11 is clearance-fitted with the rotating shaft 3. The guide part 12 and the sealing part 13 are respectively disposed at both ends of the middle part 11. The sealing part 13 abuts against the end face of the bearing 4. The guide part 12 is disposed at the top opening of the inner sleeve 1 of the acceleration wheel. There are multiple air holes 10, which are spaced apart along the circumference of the rotating shaft 3. Specifically, the longitudinal cross-section of the guide ring 9 is an "I" shaped structure. The guide ring 9 is made of metal material. There is a second air chamber 6 between the guide part 12 and the sealing part 13. Positive pressure gas enters the second air chamber 6 through the air inlet 8. The sealing part 13 plays a certain sealing role, preventing the positive pressure gas from entering one side of the bearing 4. Then, the positive pressure gas is blown to the first air chamber 5 through the air holes 10, which disperses and guides the dust and impurities accumulated in the air chamber 2. The guide ring 9 can more thoroughly clean the dust and debris remaining in the air chamber 2, which can effectively reduce the frequency of downtime and disassembly and cleaning caused by the blockage of the acceleration wheel assembly during production. Finally, it is discharged through the negative pressure channel 7, which can clean the dust and impurities on the acceleration wheel assembly in a timely manner.

[0036] Furthermore, continue to refer to Figures 1-6 The cleaning device for the filter rod forming machine's accelerating wheel assembly also includes a seal. The seal is located at the opening of the accelerating wheel inner sleeve 1, and is fitted around the outer periphery of the guide portion 12 and abuts against the inner periphery of the accelerating wheel inner sleeve 1. Specifically, the seal is made of rubber, providing good sealing. With the seal between the guide portion 12 and the accelerating wheel inner sleeve 1, the positive pressure gas in the second air chamber 6 can only be blown towards the first air chamber 5 through the air hole 10, ensuring the consistency and stability of the positive pressure gas during the cleaning process of the air chamber 2.

[0037] Furthermore, continue to refer to Figures 1-6 The cleaning device for the filter rod forming machine's acceleration wheel assembly also includes a gas connector 14, which is located at the air inlet 8 and connected to the second air chamber 6. The gas connector 14 is also connected to a high-pressure gas tank 15. Specifically, the high-pressure gas tank 15 provides positive pressure gas, which enters the second air chamber 6 and the first air chamber 5 through the gas connector 14 and finally discharges dust and impurities through the negative pressure channel 7.

[0038] Furthermore, continue to refer to Figures 1-6The cleaning device of the accelerating wheel assembly of the filter rod making machine further comprises a start-stop assembly arranged on the gas joint 14, and the start-stop assembly is used to open or close the gas joint 14. Specifically, the start-stop assembly comprises an electromagnetic valve 16 and a timer 17, the electromagnetic valve 16 is electrically connected with the timer 17, the high-pressure gas tank 15 is connected with the gas joint 14 through the electromagnetic valve 16, and the timer 17 is electrically connected with the filter rod making machine. The timer 17 is a time relay, when the filter rod making machine is stopped, the timer 17 identifies a stop signal and outputs a signal to the electromagnetic valve 16, after receiving the signal, the electromagnetic valve 16 connects the gas joint 14, and the positive pressure gas is blown to the air chamber 2 through the gas joint 14 to clean, so that the purpose of completely cleaning the accelerating wheel assembly is achieved. After 30S, the signal of the timer 17 is disconnected, the gas joint 14 is closed, the blowing is stopped, and if the machine is started again, the blowing is immediately stopped. Under the premise that only air suction is ensured when the equipment is running, the purpose of cleaning the air chamber 2 is achieved. Through the automatic cleaning of the accelerating wheel assembly, the abrasion and corrosion caused by the accumulation of dust and impurities to the equipment can be reduced, so that the service life of the equipment is prolonged, and meanwhile, the stability and reliability of the equipment running can be improved.
