[0031] See Figure 5 and Figure 6 As shown, the extraction mechanism includes a pump 1201, a filter cloth 1202 and a bellows 1203; the pump 1201 is installed on the upper rear part of the connecting block 10; the input end of the pump 1201 is connected to the filter space 11 on the connecting block 10; the filter cloth 1202 is provided in the filter space 11 on the connecting block 10, and the filter cloth 1202 is used to filter out the old carbon powder; a bellows 1203 is provided in the docking tube 4, the left end of the bellows 1203 is connected to the end of the docking tube 4, and the right end of the bellows 1203 is rotatably connected to the left end of the connecting tube 8, and the feed pipe of the hose dragon conveyor 14 passes through the inner side of the bellows 1203.

[0032] See Figure 7-Figure 9 As shown, the feeding mechanism includes a feeding hopper 1501 and a baffle 1502; the feeding hopper 1501 is installed on the upper side of the hollow frame 2, and the feeding hopper 1501 is connected to the feeding port of the hose dragon conveyor 14; four baffles 1502 are provided in the feeding hopper 1501, and the material of the baffle 1502 is plastic.

[0033] When in use, the toner cartridge 1 is taken out of the printer, and then the movable door 3 is pulled to the right to open it, and then the bag is put on the discharge hopper 13 to fix it, and then the movable door 3 is pulled to the left to close it, and then the first servo motor 601 is controlled to drive the screw rod 602 to rotate, so that the screw rod 602 drives the sliding frame 603 and the magnet 604 to move to the right, so that the magnet 604 attracts the iron block 605 and moves to the right synchronously, and then drives the sliding block 5, the hollow shaft motor 7 and the connecting cylinder 8 to move to the right synchronously, so that the bellows 1203 is extended, and at the same time the hollow shaft motor 7 is controlled to drive the connecting cylinder 8 to rotate, so that the connecting cylinder 8 drives the rubber strip 9 to rotate, so that the rubber strip 9 is swung, so that the rubber strip 9 can scrape off the old toner adhered to the inner wall of the storage space 101, thereby preventing the old toner from adhering to the storage space 10 1 causes residue on the inner wall, and at the same time controls the pump 1201 to start, so that the pump 1201 draws the old carbon powder in the storage space 101 into the connecting tube 8 through the through hole (when the pressure in the storage space 101 is lower than that in the outside, under the influence of the outside pressure, the outside air will squeeze the baffle 1502 to deform and open, so that the outside air can enter the storage space 101 through the upper hopper 1501 and the hose dragon conveyor 14 to replenish air), so that the old carbon powder in the connecting tube 8 is sucked into the filtering space 11 through the bellows 1203, and then the filter cloth 1202 will filter out the old carbon powder in the filtering space 11, so that the old carbon powder falls down into the discharge hopper 13, and the old carbon powder in the discharge hopper 13 falls down into the bag for collection. In this way, the old carbon powder in the storage space 101 can be automatically cleaned; When the sliding block 5 moves to the rightmost end of the storage space 101, the first servo motor 601 is controlled to drive the screw 602 to stop rotating, and the hollow shaft motor 7 is controlled to drive the connecting cylinder 8 to stop rotating, so that the rubber strip 9 stops swinging, and the pump 1201 is controlled to be closed (when the pressure in the storage space 101 is equal to the outside pressure, the baffle 1502 will automatically return to its original state), and then the container filled with new carbon powder is turned upside down and inserted into the upper hopper 1501, so that the discharge port of the container enters the upper hopper 1501. During this period, when the discharge port of the container contacts the baffle 1502, the discharge port of the container will squeeze the baffle 1502 to deform and open, and as the baffle 1502 The deformation is opened, and the new carbon powder in the container will fall down into the upper hopper 1501 under the influence of gravity, and then the new carbon powder will fall into the hose dragon conveyor 14 through the upper hopper 1501, so as to complete the loading of the new carbon powder, and then control the first servo motor 601 to drive the screw rod 602 to reverse, so that the screw rod 602 drives the sliding frame 603 and the magnet 604 to move to the left and reset, so that the magnet 604 absorbs the iron block 605 and moves to the left synchronously, and then drives the sliding block 5, the hollow shaft motor 7 and the connecting tube 8 to move to the left and reset synchronously, so that the bellows 1203 is shortened, and at the same time the hose dragon conveyor 14 is controlled to start, so that the hose dragon conveyor 14 can transfer the new carbon powder to the upper hopper 1501. The powder is sent into the storage space 101 through the hollow shaft of the hollow shaft motor 7, so as to realize automatic filling of the storage space 101 in the toner cartridge 1, and adopts the powder filling method from right to left, which can make the new toner evenly distributed in the storage space 101. When the sliding block 5 approaches the leftmost end of the storage space 101, it means that the powder filling operation of the new toner is nearly completed. At this time, the container is pulled out from the upper hopper 1501. When the discharge port of the container is separated from the baffle 1502, the baffle 1502 will automatically return to its original state. As the baffle 1502 returns to its original state, the baffle 1502 can not only prevent foreign matter from falling into the upper hopper 1501, but also prevent The new toner remaining in the upper hopper 1501 and the hose dragon conveyor 14 will not float into the outside and cause environmental pollution. The hose dragon conveyor 14 will then continue to convey the remaining new toner to the storage space 101. When the sliding block 5 returns to the leftmost end of the storage space 101, it indicates that the injection operation of the new toner has been completed. At this time, the first servo motor 601 is controlled to drive the screw 602 to stop reversing, and the hose dragon conveyor 14 is controlled to close. Then, the movable door 3 is pulled to the right again to open it, and then the bag is taken out from the discharge hopper 13.

The second heat fuser 25 is used to perform heat-melting edge sealing on the bottom and top of the film roll. The distance between the second heat fusers 25 on the left and right sides is smaller than the distance between the cutters 2402 on the left and right sides; a compression spring 26 is connected between the second heat fuser 25 and the cutter 2402.

[0037] Before use, first take the toner cartridge 1 out of the printer, then pull the movable door 3 to the right and open it, then put the two rolls with the film rolls on the two expansion shafts 2002 respectively, and then control the expansion shafts 2002 to fix the rolls with the film rolls, then pull the head end of the film roll down against the surface of the discharge hopper 13, so that the head end of the two film rolls pass between the conveying wheels 22 on the left and right sides, so that the conveying wheels 22 and the first heat fuser 23 press the film rolls against the surface of the discharge hopper 13, and then control the second heat fuser 23 to press the film rolls against the surface of the discharge hopper 13. The speed motor 2001 drives the expansion shaft 2002 to rotate, so that the expansion shaft 2002 drives the reel thereon to rotate, so that the reel unwinds the film roll thereon, and at the same time controls the first heat fuser 23 to start, so that the first heat fuser 23 performs heat-melting and sealing on the sides of the two film rolls, and at the same time drives the conveying wheel 22 to rotate through the first speed reduction motor 21, so that the conveying wheel 22 continuously conveys the two film rolls downward until the head ends of the two film rolls are between the two second heat fusers 25 on the upper side, and then controls the second speed reduction motor 21 to start, so that the second heat fuser 23 performs heat-melting and sealing on the sides of the two film rolls, and at the same time controls the first ... The motor 2001 drives the expansion shaft 2002 to stop rotating, and controls the first heat fuser 23 to close, and then controls the second heat fuser 25 to open, and controls the two electric push rods 2401 to drive the two cutters 2402 to move closer to each other, so that the cutters 2402 drive the second heat fusers 25 on the left and right sides to move closer to each other.

The ends of the two film rolls are hot-melted to form a pocket structure with the bottom ends and the side edges thereof. The second heat fuser 25 is then controlled to close. The two electric push rods 2401 are then controlled to respectively drive the two cutters 2402 to move away from each other and reset. In this way, the pocket structure formed by the two film rolls can be used to collect the old toner dropped from the discharge hopper 13, thereby replacing the manual operation of putting a bag on the discharge hopper 13 to collect the old toner. The movable door 3 is then pulled to the left to close, and the toner cartridge 1 is then put back into the printer. After that, when in use, it is only necessary to use the pocket structure formed by the two film rolls to collect the old carbon powder dropped from the discharge hopper 13, and there is no need to manually put the bag on the discharge hopper 13 to collect the old carbon powder; after that, when the old carbon powder in the storage space 101 is cleaned, the second reduction motor 2001 is controlled again to drive the expansion shaft 2002 to rotate, so that the reel unwinds the film roll thereon, and at the same time, the first heat fuser 23 is controlled to start again, so that the first heat fuser 23 performs heat-melting sealing on the sides of the two film rolls, and at the same time, the first reduction motor 21 is used again to drive the conveying wheel 22 to rotate, so that the conveying wheel 22 unwinds the two film rolls. The film roll is continuously conveyed downward for a specified distance (the specified distance is the distance between the top of the first heat fuser 23 and the bottom of the second heat fuser 25 on the lower side), and then the second reduction motor 2001 is controlled again to drive the expansion shaft 2002 to stop rotating, and the first heat fuser 23 is controlled to be closed again, and then the second heat fuser 25 is controlled to be opened again, and at the same time, the two electric push rods 2401 are controlled again to drive the two cutters 2402 to move closer to each other, so that the cutters 2402 drive the second heat fusers 25 on the left and right sides to move closer to each other. When the second heat fuser 25 contacts the film roll again, the second heat fusers 25 on the left and right sides are The two film rolls will be pressed together, and at the same time, the second heat fuser 25 on the lower side will perform heat-melting sealing on the pocket structure formed by the two film rolls, so as to seal and bag the old toner in the pocket structure, and the second heat fuser 25 on the upper side will perform heat-melting sealing on the bottom of the next unformed pocket structure. At the same time, after the second heat fusers 25 on the left and right sides press the film rolls together, the second heat fusers 25 on the left and right sides will stop moving closer to each other. Then, as the cutters 2402 on the left and right sides continue to move closer, the compression spring 26 is compressed. When the cutter 2402 contacts the film roll, the cutter 2402 will cut the film roll, so that the upper and lower pockets are formed. The bag structure is separated so that the bagged old toner falls to the inner bottom of the hollow frame 2 under the influence of gravity, and then the second fuser 25 is controlled to close again, and at the same time, the two electric push rods 2401 are controlled again to drive the two cutters 2402 to move to the side away from each other and reset. During this period, the compression spring 26 gradually returns to its original state. When the compression spring 26 returns to its original state, the cutter 2402 will drive the second fusers 25 on the left and right sides away from each other through the compression spring 26, and then push the movable door 3 to move to the right to open, and then take out the bagged old toner at the bottom of the hollow frame 2, and finally pull the movable door 3 to the left to close.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
