Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] Please refer to Figures 1-9 The brush cleaning mechanism disclosed in this utility model will now be described. This utility model consists of 5 parts, as follows: Figure 1 , Figure 2 , Figure 3As shown, the device includes a support base plate 1, a carbon block feeding channel 2, a carbon block cleaning unit 3, a drive unit 4, and a dust collection unit 5. The support base plate 1 is horizontally arranged. The carbon block feeding channel 2 is installed on the top of the support base plate 1. The carbon block cleaning unit 3 is installed on the top of the support base plate 1 and is used to clean the carbon blocks in the carbon block feeding channel 2. The drive unit 4 is installed on the top of the support base plate 1 and is located behind the carbon block cleaning unit 3. The drive unit 4 is used to provide power to the carbon block cleaning unit 3. The dust collection unit 5 is installed at the bottom of the support base plate 1 and is used to collect the carbon powder that falls from the carbon block cleaning unit 3.

[0050] In this embodiment, the supporting base plate 1 is used to install the overall brush cleaning mechanism. The supporting base plate 1 has a certain ground clearance and is horizontally set with the ground. The ground clearance should be greater than the installation height of the dust collection unit 5. The carbon block feeding channel 2 is a commonly used device in existing automated production lines. The carbon blocks are arranged in an orderly manner on the carbon block feeding channel 2, and are propelled by an external pushing device to move along the carbon block feeding channel 2. By setting the carbon block cleaning unit 3 and the driving unit 4, stable cleaning force and speed can be provided, effectively removing carbon powder from the surface of the carbon blocks, significantly improving the consistency of cleaning quality and product yield. Furthermore, combined with the automatic conveying of carbon blocks by the carbon block feeding channel 2, continuous cleaning of carbon blocks can be achieved, which greatly improves cleaning efficiency compared with manual cleaning and is suitable for large-scale production needs. By setting the dust collection unit 5 and combining it with an external negative pressure device, carbon powder can be effectively collected, effectively preventing dust diffusion, improving the working environment, and facilitating centralized recycling and treatment of carbon powder, which meets the requirements of green production.

[0051] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the carbon block cleaning unit 3 includes a connecting plate 31, rolling shafts 32, and a secondary cleaning frame 34. The connecting plate 31 is installed on the top of the supporting base plate 1. The rolling shafts 32 are arranged in pairs, respectively on the upper and lower sides of the carbon block feeding channel 2. The rolling shafts 32 are rotatably connected to the side wall of the connecting plate 31. Roller-type brushes 33 are installed on the circumferential side wall of the rolling shafts 32. The secondary cleaning frame 34 is arranged in pairs and installed on the top of the supporting base plate 1. A through groove 35 is provided on the side wall of the secondary cleaning frame 34. The carbon block feeding channel 2 passes through the through groove 35. Cleaning cotton 36 is provided on both the top and bottom walls of the through groove 35. In this embodiment, the connecting plate 31 is located between the carbon block cleaning unit 3 and the driving unit 4. To enhance the structural strength, a reinforcing rib is installed on the top of the supporting base plate 1. The reinforcing rib is located on both sides of the connecting plate 31 and is fixed to the connecting plate 31 by angle iron. Preferably, as Figure 3 As shown, the rolling shaft 32 and the carbon block feed channel 2 are set at an angle of α, with 0°≤α≤30°.

[0052] The specific structure of carbon block feed channel 2 is as follows: Figure 6 As shown, it is worth noting that the carbon block feeding channel 2 has a multi-segment structure. The carbon block feeding channel 2 is disconnected at the rolling shaft 32 and the secondary cleaning frame 34. This design allows the roller brush 33 and the secondary cleaning frame to clean the passing carbon blocks from both the top and bottom, ensuring thorough cleaning and avoiding the need to flip the carbon blocks for cleaning. This design is suitable for smaller spaces. The carbon block feeding channel 2 has an inlet section and an outlet section at both ends, and two channel segments in the middle. The roller brush 33 is positioned between the inlet section and the adjacent channel segment. Limiting rods are installed on the opposite side walls of the adjacent channel segments at the inlet section, extending to the inlet section to ensure that the carbon blocks do not change direction when passing through this area due to the roller brush 33. The secondary cleaning frame is positioned between the two channel segments and between the outlet section and the channel segments. The specific structure of the secondary cleaning frame is shown below. Figure 5 As shown, the secondary cleaning frame includes a base, two mounting plates on both sides, and two upper and lower cleaning cotton connecting plates. The mounting plates on both sides and the two upper and lower cleaning cotton connecting plates together form a through groove 35. When the carbon block passes through the through groove 35, the cleaning cotton 36 on the upper and lower sides will perform secondary cleaning on the carbon block.

[0053] like Figure 7 As shown, the drive unit 4 includes a motor mounting plate 41, a servo motor 42, a drive wheel 43, driven wheels 44, and a synchronous belt 45. The motor mounting plate 41 is mounted on the top of the support base plate 1. The servo motor 42 is mounted on the side wall of the motor mounting plate 41, and the output end of the servo motor 42 passes through the motor mounting plate 41. The drive wheel 43 is mounted on the output end of the servo motor 42. The driven wheels 44 are arranged in pairs and mounted on the circumferential side wall of the rolling shaft 32. The synchronous belt 45 drives and connects the drive wheel 43 and the two driven wheels 44. In this embodiment, the positions of the drive wheel 43 and the driven wheels 44 are as follows: Figure 7 As shown, the rolling shaft 32 passes through the connecting plate 31 and the motor fixing plate 41 in sequence, and is rotatably connected to the connecting plate 31 and the motor fixing plate 41 through a double-cap deep groove ball bearing. The synchronous belt 45 is simultaneously connected to the driving wheel 43 and the driven wheel 44 for transmission. In use, the servo motor 42 starts, the driving wheel 43 starts to rotate, and drives the two driven wheels 44 to rotate in opposite directions through the synchronous belt 45, thereby driving the roller brush 33 to clean the carbon block.

[0054] like Figure 8As shown, the drive unit 4 also includes a photoelectric sensor 46 and a photoelectric sensor cam 47. The photoelectric sensors 46 are arranged in pairs and mounted on the side wall of the motor mounting plate 41. The photoelectric sensor cams 47 are also arranged in pairs and mounted on the end of the rolling shaft 32 that passes through the motor mounting plate 41. In this embodiment, the cleaning ability of the carbon block is achieved by the photoelectric sensor 46 and the photoelectric sensor cam 47 on the servo motor 42 side. The photoelectric sensor 46 records how many revolutions the photoelectric sensor cam has made to adjust the cleaning ability of the carbon block. The positions of the photoelectric sensor 46 and the photoelectric sensor cam 47 are as follows... Figure 8 As shown, the photoelectric sensor cam 47 is mounted on the rolling shaft 32 and rotates together with the rolling shaft 32. The photoelectric sensor 46 has a U-shaped structure. The photoelectric sensor cam 47 extends into the U-shaped opening of the photoelectric sensor 46. Its working principle is as follows: there is a notch on the side wall of the photoelectric sensor cam 47. Whenever the notch passes through the photoelectric sensor 46, it will be detected. From this, the cleaning ability of the carbon block can be obtained. Then, the rotation speed of the rolling shaft 32 can be changed by adjusting the servo motor 42.

[0055] like Figure 7 As shown, two mounting slots 48 are formed on the side wall of the motor mounting plate 41. The servo motor 42 is mounted on one side of the motor mounting plate 41, and two position adjustment blocks 49 are provided on the other side of the motor mounting plate 41. The position adjustment blocks 49 are connected to the servo motor 42 at the mounting slots 48 by bolts. In this embodiment, the tension of the synchronous belt 45 is achieved by adjusting the position of the servo motor 42 and the position adjustment blocks 49. The positions of the mounting slots 48 and the position adjustment blocks 49 are as follows. Figure 7 As shown, the servo motor 42 and the position adjustment block 49 are respectively set on both sides of the mounting groove 48. The bolt passes through the position adjustment block 49 and the mounting groove 48 and is threadedly connected to the servo motor 42. The bolt can slide in the mounting groove 48 to change the mounting position of the servo motor 42, so that the synchronous belt 45 can be tightened on the driving pulley 43 and the two driven pulleys 44.

[0056] like Figure 9 As shown, the dust collection unit 5 includes dust collection holes 51, a dust collection hood 52, a filter screen 54, and a flange pipe 55. Several dust collection holes 51 are formed on the top of the supporting base plate 1, and are respectively located below the rolling shaft 32 and the secondary cleaning frame 34. The dust collection hood 52 is bolted to the bottom of the supporting base plate 1. A through hole 53 is formed on the bottom wall of the dust collection hood 52. The filter screen 54 is installed on the bottom wall of the dust collection hood 52 and covers the through hole 53. The flange pipe 55 is installed at the bottom of the dust collection hood 52 and is used to connect to an external negative pressure device. In this embodiment, the positions of the dust collection hood 52, filter screen 54, and flange pipe 55 are as follows... Figure 9As shown. The dust collection hood 52 is a hollow truncated pyramid structure, and its joint with the supporting base plate 1 is sealed with a square sponge sealing strip; the joint between the dust collection hood 52 and the flange pipe 55 is sealed with a circular sponge sealing strip. The filter screen 54 is designed to allow toner to pass through, but larger pieces of toner cannot. The dust collection hood 52 is connected to an external negative pressure device via the flange pipe 55, which provides negative pressure to recover the toner.

[0057] like Figure 1 As shown, the carbon block cleaning unit 3 also includes a material channel protective cover 6, which is installed on the top of the support base plate 1, and the two ends of the carbon block feeding channel 2 extend out of the material channel protective cover 6; the drive unit 4 also includes a motor protective cover 7, which is installed on the side wall of the connecting plate 31. In this embodiment, the material channel protective cover and the motor protective cover 7 serve a safety function, protecting the operator's safety, and also preventing carbon powder from splashing, thus playing an environmental protection role.

[0058] The usage process of this utility model embodiment is as follows:

[0059] First, the carbon block product that needs to be cleaned is transported to the carbon block feed channel 2. The servo motor 42 is started, which drives the drive wheel 43 to rotate. The drive wheel 44 is driven to rotate through the synchronous belt 45, which in turn drives the rolling shaft 32 to rotate, thereby driving the roller brush 33 to perform the first cleaning of the carbon block.

[0060] Then, after the first cleaning is completed, the frame 34 is cleaned again by the cleaning cotton 36; the toner in the cleaning process enters the dust collection hood 52 through the dust collection hole 51 below.

[0061] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
