[0023] The carbon powder distribution on the surface of the powder feeding roller can be ensured to be uniform by the lead screw 3, the moving block 301 and the semi-ring-shaped scraper 303 in the cleaning assembly, so that the carbon powder accumulation or deficiency in the printing process is avoided, the printing clarity is ensured, and the excess carbon powder on the surface of the powder feeding roller can be effectively cleaned.

[0025] If the powder feeding roller lacks regular cleaning and maintenance in long-term use, dust and carbon powder may accumulate on the surface of the powder feeding roller. At this time, the rotating rod 201 is driven to rotate by the motor 2, then the horizontal bevel gear 202 is driven to rotate, then the horizontal bevel gear 202 is meshingly connected with the vertical bevel gear 203, so that the horizontal bevel gear 202 drives the vertical bevel gear 203 to rotate, and then the vertical bevel gear 203 drives the lead screw 3 to rotate. When the lead screw 3 rotates, the moving block 301 can move on the lead screw 3 because the inner wall of the threaded hole in the moving block 301 is threadedly connected with the surface of the lead screw 3, and then the semi-ring-shaped scraper 303 is driven to move, so that the accumulated carbon powder on the sponge block 604 is cleaned, and the carbon powder on the surface of the sponge block 604 is uniformly distributed, the printing clarity is ensured, the carbon powder scraped off by the semi-ring-shaped scraper 303 can be collected by the storage box 7, and the carbon powder is prevented from falling off on other elements in the printer, the storage box 7 can be disassembled by the bolt fixing mode, and the semi-ring-shaped scraper 303 is prevented from rotating by the anti-rotation rod 304.

[0026] Two support plates 102 are internally provided with rotating shafts 4, the rotating shafts 4 are internally provided with rotating sleeves 401, the rotating sleeves 401 are internally provided with fixed grooves 402, the cross section of the rotating sleeves 401 is in the shape of U, the two rotating sleeves 401 are internally provided with connecting rods 5, the connecting rods 5 are hollow structures, the connecting rods 5 are internally provided with two control blocks 502 and two clamping blocks 501 respectively, the control blocks 502 and the clamping blocks 501 are connected with connecting rods 503, the two clamping blocks 501 are provided with springs a 505, the two connecting rods 503 are cross-connected, and the intersection of the two connecting rods 503 is provided with a pin shaft 504, the two support plates 102 are provided with a roller 602, the roller 602 is provided with contraction grooves 6 at both ends, the two contraction grooves 6 are internally provided with springs b 601, one end of the spring b 601 is connected with the connecting rod 5, the roller 602 is connected with four fixed strips 603, the four fixed strips 603 are provided with sponge blocks 604, the roller 602 is provided with limiting grooves 605 at both ends, the limiting grooves 605 are internally provided with limiting rods 606, one end of the limiting rod 606 is connected with the outer end of the connecting rod 5, the bottom of the carbon powder box body 1 is provided with a storage box 7, the left and right sides of the storage box 7 are connected with the bottoms of the two support plates 102 respectively, and the bottom of the carbon powder box body 1 is provided with a powder outlet 701.

[0027] When it is necessary to install the powder feeding roller on the carbon powder box body 1, since the roller 602 is internally provided with the contraction grooves 6, one end of the connecting rod 5 on one side can be pressed, so that the connecting rod 5 is temporarily contracted in the contraction groove 6, so that one end of the connecting rod 503 on this side can be put into the rotating sleeve 401, then the control block 502 on one side is pressed, so that the control block 502 drives the clamping block 501 to contract through the connecting rod 503, so that the connecting rod 5 on this side is inserted into the rotating sleeve 401, when the clamping block 501 is positioned corresponding to the fixed groove 402, the control block 502 is released, so that the clamping block 501 rebounds under the action of the spring b 601, so that the clamping block 501 can be completely inserted into the fixed groove 402, the clamping and fixing of the connecting rod 5 and the rotating sleeve 401 on this side are completed, then since the contraction groove 6 has the spring b 601, and one end of the spring b 601 abuts against the bottom of the connecting rod 5, the pressure on the connecting rod 5 on this side is cancelled at this time, since the spring b 601 is deformed after being pressed, the spring b 601 stores elastic potential energy in the compression process, and generates elastic recovery force resisting compression, then the connecting rod 5 is ejected in the contraction groove 6, then the other connecting rod 5 is installed with the corresponding rotating sleeve 401 by using the same method, because the two limiting rods 606 are in the limiting grooves 605 in the roller 602, the connecting rod 5 is fixed with the roller 602, and the connecting rod 5 is effectively prevented from being separated from the contraction groove 6 in the process of stretching and contracting, through the four fixed strips 603 outside the roller 602, the self-rotation of the sponge block 604 can be effectively prevented when the roller 602 rotates.

[0028] Working principle:

[0029] If the powder roller lacks regular cleaning and maintenance in long-term use, dust and toner may accumulate on the surface of the powder roller. At this time, the rotating rod 201 is driven to rotate by the motor 2, then the horizontal bevel gear 202 is driven to rotate, then the horizontal bevel gear 202 is meshed and linked with the vertical bevel gear 203, so that the horizontal bevel gear 202 drives the vertical bevel gear 203 to rotate, and then the vertical bevel gear 203 drives the lead screw 3 to rotate. When the lead screw 3 rotates, the moving block 301 can move on the lead screw 3 because the inner wall of the threaded hole in the moving block 301 is connected with the surface threads of the lead screw 3, thereby driving the semi-annular scraper 303 to move, thereby cleaning the accumulated toner on the sponge block 604 and making the toner on the surface of the sponge block 604 evenly distributed, ensuring the clarity of printing. The toner scraped off by the semi-annular scraper 303 can be collected by the storage box 7 to prevent the toner from falling off and falling on other elements inside the printer. The storage box can be disassembled and assembled by screwing.

[0030] When it is necessary to install the powder roller on the toner cartridge box body 1, because the inside of the roller 602 is provided with a contraction groove 6, one end of the connecting rod 5 on one side can be temporarily contracted in the contraction groove 6 by pressing, so that the end of the connecting rod 503 on that side can be inserted into the rotating sleeve 401, and then the control block 502 on one side is pressed to drive the clamping block 501 to contract through the connecting rod 503, so that the connecting rod 5 on that side is inserted into the rotating sleeve 401. When the clamping block 501 corresponds to the fixed groove 402, the control block 502 is released to make the clamping block 501 rebound under the action of the spring b601, so that the clamping block 501 can be completely inserted into the fixed groove 402, completing the clamping and fixing of the connecting rod 5 on that side and the rotating sleeve 401. Then, because the contraction groove 6 has a spring b601, and the spring b601 abuts against the bottom of the connecting rod 5, the pressure on the connecting rod 5 on that side is cancelled. Because the spring b601 is deformed after being pressed, it stores elastic potential energy during compression and generates elastic recovery force to resist compression. Then, the connecting rod 5 is ejected from the contraction groove 6. The other connecting rod 5 is installed with the corresponding rotating sleeve 401 by the same method. Because the two limiting rods 606 are located in the limiting groove 605 inside the roller 602, the connecting rod 5 is fixed with the roller 602, and the connecting rod 5 is effectively prevented from being separated from the contraction groove 6 during extension and contraction. The four fixed strips 603 on the outside of the roller 602 can effectively prevent the sponge block 604 from rotating when the roller 602 rotates.
