DETAILED DESCRIPTION

[0041] The following describes the implementation modes of the present invention with reference to the accompanying drawings so that those skilled in the art can better understand the present invention and implement it. However, the enumerated embodiments are not intended to limit the present invention. In the absence of conflict, the following embodiments and the technical features in the embodiments may be combined with each other, wherein the same components are represented by the same figure marks.

[0042] like Figure 1 and Figure 2 As shown, the two ends of the powder collecting device 11 of the machine have pillars 11-2, and the inner side of the pillars 11-2 is provided with protrusions, which are used to engage with the jaw mouth 1-1 of the jaw 1 (see Figure 11-13 ). A powder collecting port 11-1 is provided in the middle of the column 11-2. After the machine powder collecting device 11 and the toner container 10 are engaged and docked, the powder collecting port 11-1 of the machine powder collecting device 11 is aligned with the powder outlet 10-1 of the toner container 10, and the two are sealed. The general docking process is that the toner container 10 is inserted between the two columns 11-2 of the machine powder collecting device 11, and the two columns 11-2 are pulled up so that the powder collecting port 11-1 is close to the powder outlet 10-1 of the toner container 10, and the docking seal is achieved, so that the carbon powder in the toner container enters the powder collecting port 11-1 of the machine powder collecting device 11 through the powder outlet 10-1, and the carbon powder begins to be transported.

[0043] Figure 3 The toner container 10 is provided with a rotating disk 3 on the side thereof, and a claw 1 is provided on the rotating disk. The claw 1 has a claw mouth 1-1 for accommodating a protrusion of a column 11-2.

[0044] like Figure 4 As shown in FIG. 1 , the toner container 10 is pushed between the two pillars 11-2 of the machine powder collecting device 11, and the pillars are inserted into the jaw mouth 1-1 as the toner container 10 is pushed in. Then, as the toner container 10 is pushed in continuously, the rotating disk 3 starts to rotate counterclockwise, and the jaw mouth 1-1 rises accordingly, driving the machine powder collecting device 11 to rise. Figure 5 As shown. Figure 6 As shown, the powder collecting port 11 - 1 of the machine powder collecting device 11 is closely connected with the powder discharging port 10 - 1 of the toner container 10 to form a passage.

[0045] Figure 7 It shows the state of the powder collecting port 11-1 of the machine powder collecting device 11 and the powder outlet 10-1 of the toner container 10 before the rotating disk 3 rotates. From top to bottom, they are the main view, the bottom view and the cross-sectional view. It can be seen that the powder collecting port 11-1 and the powder outlet 10-1 are misaligned.

[0046] Figure 8 It shows the state of the powder collecting port 11-1 of the machine powder collecting device 11 and the powder outlet 10-1 of the toner container 10 after docking before the rotating disk 3 rotates. From top to bottom, they are the main view, the bottom view and the cross-sectional view, and it can be seen that the powder collecting port 11-1 and the powder outlet 10-1 are aligned and tightly attached.

[0047] Fig. 9 The lifting process is shown from the side.

[0048] The process of removing the toner container 10 is opposite to the process of loading. As the toner container is pulled out in the opposite direction of loading, the rotating disk 3 rotates clockwise, the height of the claw mouth 1-1 decreases, the machine powder collecting device 11 descends, the powder collecting port 11-1 of the machine powder collecting device 11 disengages from the powder outlet 10-1 of the toner container 10, and the toner conveying stops.

[0049] like Figure 9-10 The structure diagram of an embodiment of the clamping claw 1 of the present invention is shown. The clamping claw 1 includes a clamping claw body 1-3, a clamping claw mouth 1-1 and a clamping claw gear fixing shaft 1-2. The clamping claw body 1-3 is in the shape of a semicircular disk, and the clamping claw mouth 1-1 is arranged on the outer side of the clamping claw body 1-3, and the clamping claw mouth 1-1 is in a U shape. The inner side of the clamping claw body 1-3 is provided with a clamping claw gear fixing shaft 1-2, and the fixing shaft 1-2 passes through the rotating disk 3 (see Fig.13 )'s claw hole 3-2 connects the claw 1 to the rotating disk body 3-8 of the rotating disk 3, and at the same time the fixed shaft 1-2 passes through the claw gear hole 5-1 of the claw gear 5 located on the inner side of the rotating disk body 3-8, so that the claw 1 and the claw gear 5 are connected together, and the claw 1 and the claw gear 5 achieve synchronous linkage.

[0050] Fig.11 The other possible structures of the clamping jaw 1 are shown. The shape of the clamping jaw mouth 1-1 can be U-shaped, C-shaped, V-shaped, L-shaped, groove-shaped, trapezoidal, variable-shaped, etc.

[0051] Fig.12 An exploded view of an embodiment of the rotating disk 3 is shown, Fig.13 For the assembled diagram.

[0052] The rotating disk body 3-8 of the rotating disk 3 is in the shape of a disk, with a center hole 3-1 at the center and a notch formed by a first stop notch 3-3 and a second stop notch 3-7 at the edge. The center hole 3-1 is aligned with the fixed gear hole 7-2 of the fixed gear 7, inserted, 8-2 (see Fig.15 ) The fixed gear 7 has a rotation-stopping position 7-1, and the rotation-stopping position 7-1 is connected to an external connection device (for example, a rotation-stopping position 8-4 on the main body 8, see Fig.15 ) so that when the rotating disk 3 rotates, the fixed gear 7 cannot rotate.

[0053] The fixed gear 7 and the claw gear 5 are transmitted through the bridge gear 6. The bridge gear 6 has a bridge gear hole 6-1, which is sleeved on the bridge gear fixing column 3-4 on the inner side of the rotating disk body 3-8. The bridge gear fixing column 3-4 has a hole 3-6, and the fixing column 9-1 of the gear fixing plug 9 is inserted into the hole 3-6, so that the bridge gear 6 is connected to the rotating disk body 3-8, and the bridge gear 6 can rotate relative to the rotating disk body 3-8.

[0054] Fig.14 A three-dimensional view of the inner side of the rotating disk body 3-8 is shown. A spring pull rod 3-5 is provided on the inner side of the rotating disk body 3-8 near the stop notch. The spring pull rod is used to connect the spring of the external connection device (for example, the spring column 8-3, see Fig.15 ).

[0055] Reference Fig.12 The gear fixing plug 9 includes a disc-shaped main body and a fixing column 9-1. The gear fixing plug 9 is used to rotatably mount the bridge gear 6 to the bridge gear fixing column 3-4 of the rotating disk 3. The bridge gear 6 can rotate flexibly relative to the rotating disk 3 through clearance fit.

[0056] Fig.15The structural diagram of an embodiment of an external connection device matched with the rotating disk 3 is shown. The external connection device can be a part of the toner container 10. A rotating disk column 8-2 is provided on the upper cover body 8, and the hole 7-2 of the fixed gear 7 and the central hole 3-1 of the rotating disk are inserted into the rotating disk column 8-2. The anti-rotation clamping position 7-1 on the fixed gear 7 cooperates with the anti-rotation clamping position 8-4 on the upper cover body 8 to play a anti-rotation role, so that the fixed gear will not rotate. A stop column 8-1 is provided on the upper cover body 8, and the stop column 8-1 cooperates with the first stop notch 3-3 to slide the second stop notch 3-7 to limit the rotation stroke of the rotating disk 3. Among them, when the stop column 8-1 abuts against the first stop notch 3-3, the toner container 10 and the machine powder collecting device 11 are docked. When the stop column 8-1 abuts against the second stop notch 3-7, the toner container 10 and the machine powder collecting device 11 are separated. The upper cover body 8 is provided with a spring column 8-3, the spring column 8-3 has a tension spring groove 8-6, and a spring 10 (see Fig.19 ) is fixed on the spring column 8-3 and the spring pull rod 3-5 of the rotating disk.

[0057] Fig.16 The perspective view and working state diagram of the rotating disk 3 are shown. The toner container 10 is loaded between the two columns 11-2 of the machine powder collecting device 11. The protrusion on the column 11-2 slides into the U-shaped claw mouth 1-1. The column 11-2 continues to push in the direction of the arrow, and the claw mouth 1-1 is subjected to the thrust F of the column. The claw 1 transmits the thrust G to the rotating disk 3. Because the fixed gear 7 cannot rotate, the rotating disk 3 is forced to start rotating counterclockwise. The spring pull rod 3-5 on the rotating disk stretches the tension spring 10 (see Fig.18 ), one end of the tension spring 10 is fixed to the tension spring groove 8-6 of the spring column 8-3 (see Fig.15 ), and the other end is fixed on the spring pull rod 3-5.

[0058] Because the fixed gear 7 does not move, the rotating disk 3 rotates counterclockwise, thus driving the bridge gear 6 to rotate counterclockwise, the bridge gear 6 drives the claw gear 5 to rotate clockwise, the claw gear 5 links the claw to rotate clockwise, and the claw mouth 1-1 keeps the same direction.

[0059] Specifically, the claw gear fixing shaft 1-2 on the claw 1 is docked and fixed with the hole 5-1 on the claw gear 5 (can be glued together), which can transmit torque, and the claw mouth 1-1 will rotate clockwise synchronously with the claw gear 5, so as to keep the claw mouth 1-1 in the same direction during the rotation of the rotating disk 3, so as to prevent the column 11-2 of the machine powder collecting device 11 from slipping off the claw mouth 1-2. Fig.17 As shown. Then, as the toner container 1- is installed and pushed in, the jaw mouth 1-1 drives the machine powder collecting device 11 to rise, and the rising end point is as shown. Fig.19As shown, the stop post 8-1 contacts the first stop notch 3-3, and the powder receiving port 11-1 is closely connected with the powder outlet 10-1 of the toner container 10 to form a passage.

[0060] The unloading process of the toner container 10 is opposite to the loading process. As the toner container 10 is pulled out in the opposite direction of loading, the rotating disk 3 is subjected to the downward pulling force of the machine powder collecting device 11 and the pulling force of the spring pull rod 3-5 on the rotating disk 3. Under the action of these two forces, the rotating disk 3 rotates clockwise. During this process, the bridge gear 6 is driven by the reaction force of the fixed gear 7 to rotate clockwise, and the bridge gear 6 drives the claw gear 5 to rotate counterclockwise. Since the claw gear fixed shaft 1-2 on the claw 1 is docked and fixed with the hole 5-1 on the claw gear 5, torque can be transmitted, and the claw mouth 1-1 rotates counterclockwise synchronously with the claw gear 5. At the same time, the height position of the claw mouth 1-1 is lowered, and when it drops to the lowest point (see Fig.18 ), the stop post 8-1 contacts the second stop notch 3-7, the powder collecting port 11-1 of the machine powder collecting device 11 is separated from the powder outlet 10-1 of the toner container 10, and the toner conveying stops.

[0061] In cooperation with the toner container 10, two rotating disks are required, one is placed on each side of the toner container 10. The two rotating disks are symmetrical in structure, and the rotating disk described above is located on the left side of the toner container 10.

[0062] The embodiments described above are only preferred specific implementations of the present invention. This specification uses the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments" to refer to one or more of the same or different embodiments according to the present disclosure. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
