However, the following problems arise in the actual operation of the toner supply:
1. there is no powder feeding mechanism at the powder outlet at the front end of the powder box, so that the powder feeding is realized by continuously extruding the front powder by the back powder, and thus, the problem exists that when the powder in the powder cylinder is about to be used up, the back powder can not extrude the front powder any more to achieve the purpose of feeding the powder, and as a result, the residual powder amount is increased, and the utilization rate of the carbon powder is reduced, which is not economical for users. Particularly, under the condition of less powder amount in the later period, the remaining powder cannot be conveyed out of the powder outlet through the blades of the stirring frame;
2. because the inner hole at the front end of the powder cylinder is suddenly changed, and the stirring frame has the through hole, the powder feeding capacity of the stirring frame in the whole powder feeding process is the same, so that the problem exists that the same powder feeding capacity cannot enable enough carbon powder to be fed from the large hole end to the small hole end at the suddenly changed position of the inner hole, and the situation is particularly prominent when less powder is available in the later period.

Detailed Description
Referring to fig. 1 and 2, fig. 1 is a perspective exploded view of the toner supply device of the present invention after removing the toner cartridge; FIG. 2 shows a cross-sectional view of the toner supply along the axial direction of the toner cartridge. The toner supply includes a toner cartridge 10, a toner cartridge end cap 1, a stirring frame blade 2, a sealing member 4, and a coupling member 3. The powder tube end cover 1 is sleeved at the front end of the powder tube 10, and the front part of the powder tube end cover 1 is provided with a through hole for the connection component 3 to extend into. The sealing element 4 is tightly matched with the inner surface of the column body of the connecting component 3, the side surfaces of the sealing element 4 and the connecting component 3 are provided with powder outlets, the two powder outlets are corresponding in the circumferential direction but staggered in the axial direction, a normally closed state is realized, and the sealing element 4 can move relative to the connecting component 3 along the axial direction. When the sealing member 4 moves to a certain position, the powder outlet of the sealing member 4 is aligned with and communicated with the powder outlet of the connecting member 3, so that powder is discharged. A control rod 6, which is sleeved with a spring 7, passes through the central hole of the sealing element 4, one end of the control rod 6 extends out of the sealing element and is locked by a cotter pin 8, and the other end extends into the coupling member 3. The axial movement of the sealing element 4 relative to the connecting component 3 is mainly driven by the control rod 6, and after the carbon powder supplier is installed in the imaging device, one end of the ejector rod of the imaging device, which extends into the connecting component 3, is pushed against the control rod 6, so that the two powder outlets are aligned. The stirring frame blade 2 is arranged in the powder cylinder and is fixed at the inner side of the powder cylinder end cover 1 through a screw 9.
Referring to fig. 2-5, fig. 2-5 respectively show the front view, the back view, the top view and the left view of the stirring frame blade of the toner supplier of the present invention. The stirring frame blade 2 comprises a spiral main curved surface, and the main curved surface is provided with a small-diameter outlet end with a tail end penetrating into the end cover of the powder cylinder; two top corners of the main curved surface are respectively provided with a threaded hole 22, and the threaded holes 22 are used for penetrating screws 9 so that the stirring frame blade 2 is fixed on the inner side of the powder cylinder end cover 1; two sides of the spiral main curved surface are respectively provided with a spiral protruding rib 21, and the two ribs 21 are symmetrically arranged on the stirring frame blade along the main curved surface.
Referring to fig. 1, the coupling member 3 is sleeved on the powder cylinder end cover 1 and can move axially along the powder cylinder end cover 1; a connecting member spring 5 is arranged between the connecting member 3 and the stirring frame blade 2, and one end of the connecting member spring 5, which is positioned at the stirring frame blade 2, is propped against one end line of the main curved surface of the stirring frame blade 2 and the two ribs 21.
The utility model discloses the mode that the carbon dust supplier adopted spiral stirring frame blade to send powder at the front end increases its powder feeding ability of hole sudden change department including, and extend this blade send the powder end to the downthehole until going out powder mouth department always, it is important, there are two prominent ribs on this spiral stirring frame blade, and these two ribs distribute at stirring frame blade both sides symmetrical basically, the rib maximum diameter is greater than the minimum diameter play of powder section of thick bamboo end cover, and be less than the diameter of stirring frame blade, the benefit of doing so is guaranteed promptly can not reduce the powder feeding passageway of carbon dust when initial stage powder is many, and guaranteed to increase the powder of sending through these two ribs when later stage powder is low, thereby guarantee its normal play powder volume, so that the remaining carbon dust utilization ratio is higher. Meanwhile, the two ribs can also play a role in supporting the spring, so that the pivots of the original spring are increased from two to four, the spring is not likely to swing left and right during working so as to cause friction with peripheral parts, and the torque during installation is reduced.
