[0042] It should be noted that the machine body 1 is an existing printer.

[0043] See also Figure 2 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.15 and Fig.17 The limiting mechanism 3 includes a movable block 31 slidably connected to the groove wall of the installation groove 2, the movable block 31 is L-shaped, a return spring 32 is fixedly connected to the lower part of the movable block 31, a limiting rod 33 is fixedly connected to the groove wall of the installation groove 2, the limiting rod 33 is slidably connected to the movable block 31, the return spring 32 is sleeved on the outer side of the limiting rod 33, and an adjusting block 34 is fixedly connected to the upper part of the two movable blocks 31, a first rectangular groove 35 is opened in the middle of the surface of the adjusting block 34, and a first rack plate 3 is fixedly connected to the groove wall of the first rectangular groove 35 6. The surface of the first rack plate 36 is meshedly connected with a transmission gear 37, and the outer side of the transmission gear 37 is meshedly connected with a second rack plate 38. The surface of the second rack plate 38 away from the transmission gear 37 is slidably connected with a U-shaped plate 39. The U-shaped plate 39 is fixedly connected to the placement rack 13. The end of the surface of the U-shaped plate 39 away from the placement rack 13 is slidably connected with a positioning block 310. The surface of the placement rack 13 is located on the left and right sides of the U-shaped plate 39 and is fixedly connected with a clamping block 311. Both clamping blocks 311 are installed in cooperation with the adjustment block 34.

[0044] It should be noted that the limiting mechanism 3 can limit the placement of the powder box body 14 to ensure stable matching and installation between the placement frame 13 and the powder box body 14;

[0045] When the powder box body 14 needs to be replaced, the flip cover 11 is opened, and the replacement personnel places the thumb on the surface of the adjustment block 34 between the two card blocks 311, and the index finger and the middle finger are in contact with the surface of the powder box body 14 away from the placement rack 13, and the placement rack 13 is pulled out of the placement slot 12. The thumb exerts force to move the movable block 31 to the upper end of the installation slot 2. In this process, since the first rack plate 36 is fixedly connected to the groove wall of the first rectangular groove 35, the first rack plate 36 moves with the adjustment block 34, and is driven by the transmission gear 37 to drive the second rack plate 38 to move toward the direction close to the placement rack 13, and the positioning block 310 is separated from the used powder box body 14, so that the used powder box body 14 can be easily removed;

[0046] The powder box body 14 containing toner is placed on the surface of the placement rack 13, and the third round wheel 628 is in contact with the surface of the second round wheel 627. The replacement personnel also places the thumb on the surface of the adjustment block 34 between the two blocks 311, and the index finger and the middle finger are in contact with the surface of the powder box body 14 away from the placement rack 13, pushing the placement rack 13 to move toward the inside of the placement slot 12. At the same time, the thumb is used to adjust the adjustment block 34 to move in the direction of stretching the reset spring 32, so that the adjustment block 34 can be separated from the block 311. Then, under the elastic force of the reset spring 32, the adjustment block 34 moves in the direction close to the placement rack 13, and the second inclined groove 6210 and the trapezoidal block 621 slide relative to each other, driving the trapezoidal block 621 to move in the direction away from the block 311, and then the adjustment block 34 is adjusted to move in the direction of stretching the reset spring 32.

[0047] It should be noted that after the adjustment of the adjustment block 34 is completed, the first rack plate 36, the transmission gear 37 and the second rack plate 38 are driven to adjust the positioning block 310 to rotate, automatically completing the placement and positioning of the powder box body 14, shortening the time required to replace the powder box body 14 and further improving the replacement efficiency.

[0048] See also Fig.11 , the initial state of the return spring 32 is a stretched state;

[0049] It should be noted that the reaction force generated by the stretching of the return spring 32 acts on the surface of the movable block 31, and the movable block 31 is fixedly connected to the adjustment block 34, so that the two clamping blocks 311 can stably cooperate with the adjustment block 34, thereby temporarily placing and positioning the placement rack 13, thereby facilitating the replacement of the powder box body 14.

[0050] See also Fig.14 and Fig.15, a first inclined groove 312 is formed on the surface of the positioning block 310;

[0051] It should be noted that the provision of the first inclined groove 312 enables the second rack plate 38 to move in a direction away from the placement frame 13 , thereby driving the positioning block 310 to move in a direction close to the powder box body 14 , thereby placing and positioning the powder box body 14 .

[0052] See also Figure 1 , Figure 3 , Figure 5 , Figure 8 , Fig. 9 , Fig.14 and Fig.18 , the adjusting assembly 62 includes a trapezoidal block 621 slidably connected to the right side of the adjusting block 34, the trapezoidal block 621 is slidably connected to the side of the placement rack 13, the surface of the trapezoidal block 621 away from the adjusting block 34 is rotatably connected to a rotating column 622, the surface of the rotating column 622 is provided with a first spiral groove 623, the groove wall of the first spiral groove 623 is matched with a protrusion 624, the side of the placement rack 13 is located on the right side of the trapezoidal block 621 and is fixedly connected to a connecting ring 625, there are two connecting rings 625, both of which are rotatably connected to the rotating column 622, one of which is fixedly connected to the protrusion 624, and the end of the rotating column 622 away from the trapezoidal block 621 is slidably connected to a first round wheel 626, the outer side of the first round wheel 626 is matched with a second round wheel 627, the outer side of the second round wheel 627 is matched with a third round wheel 628, and the second round wheel 627 is rotatably connected to the placement rack 13;

[0053] It should be noted that when the adjustment block 34 moves in the direction of compressing the reset spring 32 or stretching the reset spring 32, the adjustment block 34 cooperates with the second inclined groove 6210 to drive the trapezoidal block 621 to move, and the rotating column 622 moves with the trapezoidal block 621. A relative movement occurs between the first spiral groove 623 and the protrusion 624, and the rotating column 622 rotates as the trapezoidal block 621 moves. A relative sliding occurs between the plurality of strip grooves 629 and the first round wheel 626, and the first round wheel 626 rotates as the rotating column 622 rotates. The outer sides of the round wheel 626, the second round wheel 627 and the third round wheel 628 can be covered with a layer of rubber ring, so that the rotation of the first round wheel 626 can drive the second round wheel 627 to rotate, and the rotation of the second round wheel 627 can drive the third round wheel 628 to rotate. The rotating ring 611 rotates with the rotation of the third round wheel 628. The adjusting component 62 plays an adjusting role, which can adjust the multiple first rotating rods 618 and the second rotating rods 619 to extend or contract, and can also adjust the multiple first rotating rods 618 and the second rotating rods 619 to rotate to stir the agglomerated toner.

[0054] See also Figure 1 and Figure 3 A plurality of strip grooves 629 are formed on the surface of the rotating column 622 at one end away from the trapezoidal block 621, and the plurality of strip grooves 629 are all slidably connected to the first round wheel 626;

[0055] It should be noted that the provision of the strip groove 629 can limit the first round wheel 626 , so that the rotation of the rotating column 622 can stably drive the first round wheel 626 to rotate.

[0056] See also Fig.10 and Fig.13 A second inclined groove 6210 is provided on the surface of the adjusting block 34, and the second inclined groove 6210 is slidably connected to the trapezoidal block 621;

[0057] It should be noted that the second inclined slot 6210 can generate relative movement with the adjustment block 34 , thereby adjusting the movement of the trapezoidal block 621 .

[0058] See also Figure 6 , Figure 7 , Fig.17 and Fig.18 The stirring assembly 61 includes a rotating ring 611 fixedly connected to the surface of the third round wheel 628, and the end of the rotating ring 611 close to the feed port 5 is rotatably connected to a circular block 612. The surface of the circular block 612 is symmetrically provided with limiting holes 613, and the hole wall of the limiting hole 613 is slidably connected with a movable rod 614. One end of the two movable rods 614 is fixedly connected with a top block 615. The surface of the circular block 612 away from the rotating ring 611 is provided with a second rectangular groove 616, and the two limiting holes 613 are both connected to the second rectangular groove 616. The groove wall of the second rectangular groove 616 is rotatably connected with a cross bar 617. The first rotating Rod 618 and second rotating rod 619, the first rotating rod 618 is rotatably connected with the second rotating rod 619, wherein the two first rotating rods 618 are rotatably connected with the cross rod 617, wherein the two second rotating rods 619 are rotatably connected with one end of the two movable rods 614 away from the top block 615, respectively, one end of the two movable rods 614 away from the top block 615 is fixedly connected with a connecting spring 6110, and the other ends of the two connecting springs 6110 are fixedly connected with the groove wall of the second rectangular groove 616, the inner wall of the rotating ring 611 is provided with a second spiral groove 6111, and the top block 615 is installed in coordination with the second spiral groove 6111;

[0059] It should be noted that protrusions may be equidistantly arranged at the surface edges of the first rotating rod 618 and the second rotating rod 619, so that the first rotating rod 618 and the second rotating rod 619 can drive the toner in the toner bin 4 to move like a hair comb combing hair in reality, ensuring that the toner is evenly distributed after adjustment;

[0060] It should be noted that the stirring component 61 can stir the toner inside the powder bin 4, break up the agglomerated toner, and take the broken up toner away from the agglomerated position, so as to ensure that the toner is loose and evenly distributed inside the powder bin 4, thereby ensuring the printing quality;

[0061] Specifically, the first round wheel 626, the second round wheel 627 and the third round wheel 628 drive the rotating ring 611 to rotate. The inner wall of the rotating ring 611 is provided with a second spiral groove 6111. As the rotating ring 611 rotates, the second spiral groove 6111 and the top block 615 move relative to each other. The top block 615 moves toward the direction close to the circular block 612, and the connecting spring 6110 is gradually stretched. The first rotating rods 618 and the second rotating rods 619 are stretched out and inserted into the toner agglomeration in the powder bin 4. , when the top block 615 moves to the end of the second spiral groove 6111 close to the circular block 612, the first rotating rod 618 and the second rotating rod 619 are fully extended, at this time, the first round wheel 626, the second round wheel 627 and the third round wheel 628 can continue to rotate, and the rotating ring 611 rotates with the third round wheel 628, which can drive the circular block 612 to rotate together, that is, after the plurality of first rotating rods 618 and the second rotating rods 619 are extended, they rotate again to stir the toner and break up the agglomerated toner, and then The first round wheel 626, the second round wheel 627 and the third round wheel 628 are adjusted to rotate in opposite directions, and relative movement occurs between the second spiral groove 6111 and the top block 615, and the plurality of first rotating rods 618 and the second rotating rods 619 are contracted. Since the first rotating rods 618 and the second rotating rods 619 have a certain thickness, they can drive the toner to move in the direction close to the circular block 612. Thereafter, the extension or contraction of the plurality of first rotating rods 618 and the second rotating rods 619 can drive the toner to move, and can ensure that the toner is loose and evenly distributed inside the powder bin 4, thereby ensuring the printing quality; the entire stirring and loosening step is carried out in the process of pushing the placement rack 13 and the powder box body 14 into the placement groove 12, that is, in the process of pushing the powder box body 14 into the placement groove 12, the stirring and loosening of the toner in the powder bin 4 is completed at the same time, which optimizes the step of replacing the powder box body 14, thereby improving the replacement efficiency, and can avoid judging the shaking condition of the toner by the feel of shaking during the replacement process, so as to reduce misjudgment, thereby ensuring the printing quality;

[0062] It should be noted that the multiple first rotating rods 618 and the second rotating rods 619 occupy a small amount of space at one end of the powder bin 4 close to the circular block 612, which will not affect the amount of toner stored inside the powder bin 4, and can be disassembled by adjusting the circular block 612 to separate it from the feed port 5, without affecting the re-addition of toner into the powder bin 4.
