The circumferential side wall of the rotating shaft 200 is fixedly provided with a powder scraping sheet 700 and a plurality of helical blade sets which are arranged at equal intervals along the axial direction of the rotating shaft; all the spiral blade groups are positioned on one side of the powder scraping sheet 700 far away from the gear 201; more specifically, the powder outlet 102 is located at a position of the circumferential sidewall of the container body 100 corresponding to the powder scraping sheet 700, the movement track of the powder scraping sheet 700 corresponds to the powder outlet 102, one end of the powder scraping sheet 700 is fixed on the rotating shaft 200, the other end of the powder scraping sheet extends towards the circumferential sidewall of the inner cavity of the container body 100, the outer edge of the powder scraping sheet 700 is 0.1mm-0.3mm away from the circumferential sidewall of the inner cavity of the container body 100, in operation, the spiral blade set pushes the carbon powder towards the powder outlet 102, and when the carbon powder reaches the circumferential sidewall near the powder outlet 102, the powder scraping sheet 700 scrapes the carbon powder on the circumferential sidewall near the powder outlet 102 towards the powder outlet 102 so as to assist the powder outlet 102 in discharging powder.

Wherein each helical blade group comprises a first blade 400 and a second blade 300, and preferably, the structure of the first blade 400 is the same as that of the second blade 300; first blade 400 and second blade 300 are located the relative both sides of pivot 200 circumference lateral wall respectively, and first blade 400 is located one side that second blade 300 closes on powder outlet 102, can make first blade 400 misplace each other with second blade 300 in pivot 200 radial direction like this, can conveniently push away the carbon powder. The first blade 400 and the second blade 300 both comprise a straight line section 401 and a spiral section 402, and the straight line section 401 of the first blade 400 and the straight line section 401 of the second blade 300 are parallel to each other; all the straight line segments 401 are perpendicular to the axis of the rotating shaft 200, one end of the straight line segment 401 is fixedly connected with the rotating shaft 200, the other end of the straight line segment 401 is connected with the spiral segment 402, and preferably, the side surface of the end part of the straight line segment 401 is in arc transition with the side surface of the spiral segment 402, which is adjacent to the circumferential side wall of the inner cavity of the container body 100. One end of the spiral section 402, which is far away from the straight section 401, extends spirally along the circumferential direction of the inner cavity of the container body 100, and the extending direction of the spiral section faces the powder outlet 102, so that carbon powder can be pushed to the powder outlet 102. In addition, the straight line section 401 can fix the spiral section 402 at a position close to the circumferential side wall of the inner cavity of the container body 100, when the container body 100 works, the spiral section 402 rotates along the circumferential side wall of the inner cavity of the container body 100, even if the amount of the carbon powder in the carbon powder box is less, the spiral section 402 can contact the carbon powder and continue to convey the carbon powder, moreover, the container body 100 is generally transversely placed, the spiral section 402 mainly conveys the carbon powder far away from the circumferential side of the axis of the container body 100, therefore, after the carbon powder on the circumferential side of the axis of the container body 100 is conveyed forwards, the carbon powder in the middle of the axis of the container body 100 can sink under the action of self gravity to make up; in contrast, the helical blades in the traditional carbon powder cylinder are mostly concentrated at the middle axis part of the carbon powder cylinder, and when the amount of the carbon powder is less, the residual carbon powder is difficult to convey. In addition, the spiral section 402 is connected with the rotating shaft 200 only through the straight line section 401, compared with the traditional spiral conveying rod, the area of the connecting part between the spiral section 402 and the rotating shaft 200 is smaller, so that the contact area between a conveying part and carbon powder can be prevented from being larger, and the excessive heat generated by friction is avoided; the area of the spiral section 402 is small, reducing frictional heat generation.

The spiral section rotating track of the first blade 400 in any one spiral blade group is at least partially overlapped with the straight section rotating track of the second blade 300 in another adjacent spiral blade group close to one side of the powder outlet 102, preferably, the rotating track of the tail end of the spiral section 402 of the first blade 400 is at least partially overlapped with the straight section rotating track 401 of the second blade 300 on another adjacent spiral blade group which is positioned at one side of the first blade 400 close to the powder outlet 102, and can also be completely overlapped, when the powder dust collector works, the first blade 400 pushes the carbon powder to the pushing position of the second blade 300 of another spiral blade group, and then the second blade 300 can continue to push the carbon powder forwards. The spiral section rotating track of the second blade 300 in any one spiral blade group is located between the rotating track of the straight section of the second blade 300 and the rotating track of the straight section of the second blade 300 in another spiral blade group adjacent to one side of the gear 201, the second blade 300 has the function of assisting in pushing carbon powder, and when the helical blade assembly works, one of the second blades 300 pushes the carbon powder forward to the pushing range of the adjacent first blade 400, so that the first blade 400 continues to push the carbon powder. This improves the efficiency of toner delivery and uniformity of toner delivery. Preferably, as shown in fig. 5, a first blade 400a, a second first blade 400b and a third first blade 400c are defined in sequence from bottom to top, and a first second blade 300a, a second blade 300b and a third second blade 300c are defined in sequence from bottom to top; the first blade 400a and the first second blade 300a, the second first blade 400b and the second blade 300b, and the third first blade 400c and the third second blade 300c respectively form three spiral blade groups, wherein the conveying end of the spiral section 402 of the first blade 400a is positioned above the straight line section 401 of the second blade 300b, so that the rotation trajectory of the spiral section 402 of the first blade 400a and the rotation trajectory of the straight line section 401 of the second blade 300b are partially overlapped; the delivery end of the helical section 402 of the second first blade 400b is positioned above the straight section 401 of the third second blade 300c, so that there is a partial overlap between the rotational trajectory of the helical section 402 of the second first blade 400b and the rotational trajectory of the straight section 401 of the third second blade 300 c; during operation, the first second blade 300a conveys the carbon powder forward to the conveying range of the first blade 400a, the spiral section 402 of the first second blade 300a conveys the carbon powder from the conveying end to the linear section 401 starting position of the second blade 300b, the spiral section 402 of the second blade 300b conveys the carbon powder to the conveying range of the spiral section 402 of the second first blade 400b, then the spiral section 402 of the second first blade 400b conveys the carbon powder from the conveying end to the starting position of the linear section 401 of the third second blade 300c, and the third second blade 300c conveys the carbon powder to the conveying range of the third first blade 400 c.
