[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 1 to 6 The embodiment of the present application provides a carbon powder collection device, which is applied to a phase regulator excitation brush holder 1. The phase regulator excitation brush holder 1 includes a housing 11, a fixing frame 12 arranged in the housing 11, a carbon brush assembly 13 and a collector ring 14; the carbon powder collection device includes a dust suction pipe 2, a connecting component 3 and a fan assembly 4. The dust suction pipe 2 is arranged on the fixing frame 12. The dust suction pipe 2 has a dust suction nozzle 21. The dust suction nozzle 21 is aligned with the contact position of the carbon brush assembly 13 and the collector ring 14. One end of the connecting component 3 is connected to the output end of the dust suction pipe 2, and the other end is connected to the fan assembly 4.

[0034] In the present application, negative pressure suction is generated by the fan assembly 4, and suction is generated at the dust nozzle 21 of the dust pipe 2 through the connecting assembly 3, so that the carbon powder generated between the carbon brush assembly 13 and the collector ring 14 can be sucked in time, and the cleaning and collection of the carbon powder can be completed automatically, saving labor costs.

[0035] In the related art, during the operation of the phase shifter excitation brush holder 1, the friction between the carbon brush and the collector ring 14 will generate fine carbon powder, which will be scattered on the insulating parts between the collector ring 14 and the brush holder and all over the unit, causing the insulation of the excitation brush holder 1 to decrease. Currently, it is cleaned manually on a regular basis. Before cleaning, the carbon powder is still scattered on the insulating parts between the collector ring 14 and the brush holder and all over the unit, affecting the insulation performance of the excitation brush holder 1. In the present application, the generated carbon powder can be sucked and cleaned in real time during the operation of the excitation brush holder 1, so as to avoid the carbon powder being scattered on the insulating parts and all over the unit and affecting the insulation performance of the excitation brush holder 1. At the same time, compared with manual cleaning, it improves labor saving and reduces maintenance costs.

[0036] Specifically, the fan assembly adopts a centrifugal fan to ensure the suction force of the carbon powder at the dust suction pipe.

[0037] In some embodiments, the dust suction nozzle 21 protrudes to the outside of the outer surface of the dust suction tube 2 , and a gap is left between the dust suction nozzle 21 and the collector ring 14 .

[0038] In the present application, the dust nozzle 21 protrudes to the outside of the outer surface of the dust suction tube 2, so that the dust nozzle 21 can be sufficiently close to the outer surface of the collector ring 14, and sufficient space can be left on both sides of the dust nozzle 21 to facilitate carbon powder to enter the dust nozzle 21 from both sides of the dust nozzle 21.

[0039] In some embodiments, the dust suction nozzle 21 is extended along the axial direction of the dust suction pipe 2, and the dust suction nozzle 21 is a strip-shaped structure.

[0040] In the present application, the dust nozzle 21 is arranged in a strip shape and is extended along the axial direction of the dust suction tube 2, so that uniform suction can be generated at the dust nozzle 21 to ensure the adsorption effect of carbon powder on the outer surface of the collector ring 14, and the dust nozzle 21 will not have insufficient local suction.

[0041] Specifically, the length of the dust nozzle 21 is equal to the axial width of the collector ring 14 , and the carbon powder generated on the entire outer surface of the collector ring 14 can be adsorbed. During the rotation of the collector ring 14 , the entire outer surface of the collector ring 14 can pass through the opening of the dust nozzle 21 .

[0042] In some embodiments, a plurality of dust suction pipes 2 are disposed around the outer circumference of the collector ring 14 , and the number of the dust suction pipes 2 is equal to the number of the carbon brush assemblies 13 .

[0043] In the present application, each dust suction pipe 2 corresponds to a carbon brush assembly 13. Specifically, the dust suction pipe 2 is adjacent to the carbon brush assembly 13 and is located downstream of the carbon brush assembly 13 along the rotation direction of the collector ring 14, so that the generated carbon powder can be cleaned in time to ensure the cleaning effect of the carbon powder.

[0044] In some embodiments, the connecting component 3 includes: a sealing shell 31, which is arranged on the outer surface of the casing 11, and a cavity is arranged inside the sealing shell 31; an air pipe joint 32, which is arranged on the sealing shell 31 and connected to the cavity; a connecting air pipe 33, one end of the connecting air pipe 33 is connected to the dust suction pipe 2, and the other end is connected to the air pipe joint; and a bellows 34, one end of the bellows 34 is connected to the air inlet end of the fan assembly 4, and the other end is connected to the cavity.

[0045] In the present application, a sealed shell 31 is provided, one end of the communicating air pipe 33 is connected to the dust suction pipe 2, and the other end is connected to the sealed shell 31 through the air pipe joint 32, so that multiple dust suction pipes 2 can be assembled into the sealed shell 31, and then connected to the sealed shell 31 through the fan assembly 4 and the bellows 34, so that multiple dust suction pipes 2 can generate stable adsorption force. The situation that the adsorption force of multiple dust suction pipes 2 is uneven and the toner absorption effect is affected is avoided.

[0046] In some embodiments, the carbon powder collecting device further includes a collecting box 5 and a filter cartridge 6 disposed in the collecting box 5 . The fan assembly 4 is disposed in the collecting box 5 , and the output end of the fan assembly 4 extends into the filter cartridge 6 .

[0047] In the present application, the fan assembly 4 delivers the carbon powder into the filter cartridge 6 , which is filtered through the filter cartridge 6 , and the clean air can be discharged through the exhaust port of the collection box 5 .

[0048] In some embodiments, a collection box 7 is further included in the collection box 5 . The collection box 7 is located below the filter cartridge 6 and is used to collect the carbon powder filtered by the filter cartridge 6 .

[0049] In the present application, the carbon powder is filtered by the filter cartridge 6, the carbon powder adheres to the surface of the filter cartridge 6 and falls into the collection box 7 below. The collection box 7 can be pulled out from the bottom of the collection box 5, and the carbon powder in the collection box 7 is cleaned regularly.

[0050] In some embodiments, a back-blowing device 8 is further included. The back-blowing device 8 is disposed in the collecting box 5 . The back-blowing device 8 has a back-blowing pipe 81 extending into the filter cartridge 6 for cleaning carbon powder attached to the filter cartridge 6 .

[0051] In the present application, the back-blowing device 8 adopts pulse control, and can regularly back-blow the filter cartridge 6, so as to clean the carbon powder attached to the filter cartridge 6, so that the carbon powder is collected in the collection box 7 below, thereby ensuring the filtering effect of the filter cartridge 6 on the carbon powder.

[0052] The carbon powder collecting device generates negative pressure suction through the fan assembly 4, and generates suction at the dust nozzle 21 of the dust suction pipe 2 through the connecting assembly 3, so that the carbon powder generated between the carbon brush assembly 13 and the collector ring 14 can be timely absorbed, and the cleaning and collection of the carbon powder can be automatically completed, saving labor costs.
