The opening 101 is a cylindrical nozzle with one or more independently expanding rings 104 on its outer wall. The projected shape of the opening 102 is the same as the cross-sectional shape of the middle section of the powder storage bin 1 along the central axis direction α of the cylinder 116 .

The opening 101 is closed by a first end cap 105 in such a manner as to be inserted into the opening 101 . The shape of the first end cap 105 corresponds to that of the opening 101, both of which are circular. The opening 102 is closed by the second end cap 106 in a manner that the two can be plugged into each other.

In the inner cavity of the toner storage bin 1 closed by the first end cap 105 and the second end cap 106 , that is, in the inner cavity of the cylinder 116 , a toner stirring mechanism 3 for stirring the toner is provided. The toner mixing mechanism 3 includes a cylindrical support shaft 301 , a bracket 302 fixed on the support shaft 301 , a blade 303 fixedly connected with the bracket 302 , and a first transmission head 304 . One end of the support shaft 301 is fixed with a second transmission head 305 . The first transmission head 304 is rotatably fixed at the radial center of the first end cover 105 . The second transmission head 305 on the support shaft 301 is rotatably fixed at the radial center of the second end cover 106 . The position of the support shaft 301 relative to the shaft end 306 of the second transmission head 305 maintains a detachable fixed connection state with the first transmission head 304 along the axial direction of the support shaft 301 . In this embodiment, the position of the support shaft 301 relative to the fixed connection state between the shaft end 306 of the second transmission head 305 and the first transmission head 304 is inserted into the shaft hole provided on the first transmission head 304 through the cylindrical shaft end 306 and It is realized by the way that the bracket 302 engages with the first transmission head 304 at a position deviated from the center of the cylindrical shaft end 306, that is, the cylindrical shaft end 306 and the first transmission head 304 remain fixed in the circumferential direction of the support shaft 301. positioning status. In this way, when one of the first transmission head 304 or the second transmission head 305 receives the rotational driving torque, the support shaft 301 will form a rotation around its own central axis and keep synchronizing with the first transmission head 304 or the second transmission head 305. Rotational movement.

The component blades 303 of the above-mentioned toner stirring mechanism 3 are generally made of soft elastic materials such as plastics, as shown in FIGS. 5 and 6 . The vane 303 has a length corresponding to the inner chamber of the powder storage bin 1 along the axial direction of the support shaft 301 . In the radial direction of the support shaft 301, the distance from the outer edge of the blade 303 along the axial middle section 3031 of the support shaft 301 to the center of the support shaft 301 is smaller than the distance between the outer edges of the blade 303 along the two ends 3032, 3033 in the axial direction of the support shaft 301 to the support shaft 301 distance from the center of the circle. When the toner stirring mechanism 3 is loaded into the toner storage bin 1 , the outer edge of the blade 303 along the radial direction of the support shaft 301 is at least in contact with the cavity wall corresponding to the bottom wall 103 of the inner cavity of the toner storage bin 1 . The contact line formed between the outer edge of the blade 303 along the radial direction of the support shaft 301 and the cavity wall of the inner cavity of the powder storage bin 1 corresponding to the bottom wall 103 presents an arc. The arc forms the following form when the support shaft 301 rotates, that is, the contact formed between the part of the arc corresponding to the middle section of the blade 3031 and the inner cavity of the powder storage bin 1 corresponding to the bottom wall 103 is formed on the support shaft 301 In the direction of rotation β, it lags behind the contact formed between the part of the arc corresponding to the two ends 3032 and 3033 of the blade and the inner cavity of the powder storage bin 1 corresponding to the bottom wall 103 . When the support shaft 301 rotates, the blade 303 will push the carbon powder scattered in the inner cavity of the powder storage bin 1 corresponding to the positions of the two ends 3032 and 3033 of the blade to the position of the inner cavity of the powder storage bin 1 corresponding to the middle section of the blade 3031, so that the carbon powder is relatively concentrated in the The area where the powder outlet 107 is located. Specifically, when the blade 303 is driven by the support shaft 301 to rotate, the two ends 3032 and 3033 of the blade are like the two side walls of a bucket to concentrate the carbon powder to the middle section of the blade 3031 and then to the area where the powder outlet 107 is located.

In the state that the toner storage bin 1 is closed by the first end cover 105 and the second end cover 106 and the toner agitating mechanism 3 is installed in its inner cavity, continue to complete the assembly of the following components.

At one end of the powder storage bin 1 corresponding to the first end cover 105, the first transmission gear 108 is fixed on the side of the first transmission head 304 facing away from the inner cavity of the powder storage bin 1, while maintaining the first transmission head 304, the first transmission gear 108 and The three support shafts 301 are coaxial. When the first end cover 105 is inserted into the opening 101 and kept in a relatively fixed state, the first transmission head 304 , the first transmission gear 108 and the support shaft 301 can be synchronized relative to the first end cover 105 state of rotation. The connection between the first transmission gear 108 and the first transmission head 304 adopts the common non-circular shaft end and the corresponding non-circular bearing hole docking form, as long as the first transmission gear 108 can transmit the rotational torque to the first Transmission head 304 just.

After the first transmission gear 108 is fixed, the hollow cylindrical seal 115 is inserted into the powder storage bin 1 , that is, the outer cylindrical wall of the cylindrical barrel 116 . The bumps or protruding rings provided on the inner cylindrical wall of the cylindrical sealing member 115 and the expansion ring 104 on the outer wall of the opening 101 are interlocked together so that the sealing member 115 is fixed on the outer wall of the opening 101 . And keep the cylinder seal 115 between the outer cylindrical wall of the cylinder 116, or at least with the outer surface of the bottom wall 113 around the powder outlet 107 in a manner that the cylinder seal 115 can rotate around the axis of the cylinder 116 Keep sliding contact. Subsequently, the handle—the first end cover 109 is pressed onto the outer wall of the first end 1151 of the cylinder seal 115, and the first end cover 109 is secured by using the fastening block 1154 provided on the outer wall of the first end 1151 fixed. The second end 1152 of the cylinder sealing member 115 tightly abuts against the protrusion 117 on the outer wall of the opening 102 . In this way, the cylinder seal 115 is positioned in the axial direction α of the cylinder 116 . When the first end cover 109 rotates, the cylinder seal 115 rotates accordingly. During this rotation, the window 1153 provided on the seal 115 will form a state of being aligned with the powder outlet 107 or staggered, and the toner cartridge A just utilizes this state to realize the toner supply to the laser printer. After the first end cover 109 is pressed onto the outer wall of the first end 1151 , a part of the first transmission gear 108 is exposed at the notch. The exposed part of the first transmission gear 108 becomes the stressed part that receives the rotational torque generated by the laser printer, and it can complete the torque transmission after it is docked with the corresponding gear of the laser printer.

At one end of the powder storage bin cylinder 116 corresponding to the second end cover 106, the second transmission gear 114 is fixed on the side of the second transmission head 305 facing away from the inner cavity of the powder storage bin 1, while maintaining the second transmission head 305 and the second transmission gear 114 and the support shaft 301 are coaxial. When the second end cover 106 is inserted into the opening 102 and kept in a relatively fixed state, the second transmission head 305 , the second transmission gear 114 and the support shaft 301 can be synchronized relative to the second end cover 106 state of rotation. The connection mode between the second transmission gear 114 and the second transmission head 305 is similar to that of the first transmission head 304 and the first transmission gear 108, and also adopts a common non-circular shaft end and a corresponding non-circular bearing hole docking form, As long as the second transmission gear 114 can smoothly receive the rotational torque transmitted from the second transmission head 305 . After the second transmission gear 114 is fixed, the third transmission gear 110 and the powder feeding mechanism 111 are respectively inserted in a rotatable manner on the side of the second end cover 106 facing away from the inner cavity of the powder storage bin 1, while maintaining the second transmission gear 114 1. The third transmission gear 110 and the component of the powder feeding mechanism 111 - the fourth transmission gear 1113, the three are in a state of meshing one by one, so that the rotational torque transmitted from the second transmission head 305 passes through the second transmission gear 114 step by step Passed to the third transmission gear 110 and the fourth transmission gear 1113, finally the powder feeding mechanism 111 is formed to rotate, and the helical spring 1112 fixed on the transmission shaft 1111, which is a component of the powder feeding mechanism 111, generates a rotation motion. When the second transmission gear 114 , the third transmission gear 110 , and the powder feeding mechanism 111 are fixed, the locking plate 112 is inserted into the locking hole 1061 provided on the second end cover 106 . The locking piece 112 is provided with a transmission shaft 1121 whose axis is parallel to the support shaft 301 . When the locking piece 112 cooperates with the locking hole 1061, the transmission shaft 1121 is allowed to rotate within a predetermined angle range.

After the second transmission gear 114 , the third transmission gear 110 , the powder feeding mechanism 111 and the locking plate 112 are fixed, the bin cover 113 is fixedly inserted into the second end cover 106 . After the bin cover 113 is fixed on the second end cap 106, the second transmission gear 114, the third transmission gear 110, the fourth transmission gear 1113 of the powder feeding mechanism and the locking plate 112 are clamped in the position of the second transmission gear 114 by the bin cover 113 and the second transmission gear 110. In the interlayer cavity formed by the end cover 106, at the same time, the components of the powder feeding mechanism 111—the transmission shaft 1111 and the helical spring 1112, and the transmission shaft 1121 of the locking plate 112, pass out to the outside of the cover 113 respectively. In this state, the cover 113 has a sealing effect on the second end cover 106, so that even if the carbon powder stored in the inner cavity of the powder storage bin 1 leaks out from the pores on the second end cover 106, it enters the second end cover 106 and enters the second end cover 106. 113 and the second end cover 106 formed in the interlayer cavity will also be closed by the warehouse cover 113. On the other hand, after the installation of the above spare parts is completed, the waste toner bin 2 is fixedly nested on the second end cover 106, and the components of the bin cover 113, the powder feeding mechanism 111——the drive shaft 1111 and the coil spring 1112 and the transmission shaft 1121 of the locking plate 112, the four are included in it at the same time. Finally, insert the switch 202 that controls the switch state of the waste toner inlet 201 of the waste toner bin 2 into the inner cavity of the waste toner bin 2 through the waste toner inlet 201, so that the support rod 2021 is docked with the transmission shaft 1121 of the locking piece 112, so that Realizing the predetermined movement of the lock plate 112 in the lock hole 1061 is transformed into the control of the rotation angle of the switch 202 .
