[0002] Toner is a consumable material for printing machines. It needs to be replenished regularly and in time when the printing machine is used frequently. Since the toner itself has small particles and light weight, it is easy to adhere to the inner wall of the toner cartridge. In the southern region with high humidity, long-term accumulation can easily cause toner to adhere to the inner wall. Failure to clean it in time not only affects the utilization rate of toner, but also makes it difficult to clean it later. In order to improve the utilization rate of toner, some people will take out the toner cartridge or toner cartridge and shake or vibrate it to promote the shedding of toner. However, this method only treats the symptoms and not the root cause. The cleaning efficiency is low and it is easy to cause matching errors of toner cartridge parts, which is not worth the loss.

[0003] Announcement No. CN212701438U discloses a toner cartridge carbon stirring device for copying equipment, which utilizes the rotation of the conveying shaft to drive the stirring shaft and the powder scraping rod to rotate, thereby continuously stirring the toner in the toner cartridge. Although this method can avoid the problem of toner sticking to the wall, the toner conveying structure is prone to jamming and toner residue is easily left on the brush, which is difficult to clean, and has poor practicality.

[0017] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 4The utility model comprises a box body 1, which is a cylindrical shell with an axis horizontally placed. A powder outlet 2 is provided on the lower side of the outer edge of the box body 1, and a developing roller 3 is provided at the position of the powder outlet 2; a shaking bin 4 is fixed to the right end of the cavity of the box body 1, and a powder adding port 5 is provided on the right end face of the shaking bin 4; a guide tube 6 is coaxially provided on the inner side of the box body 1, and the left end of the guide tube 6 is fixedly connected to the left end face of the box body 1, and a sleeve 7 is provided on the guide tube 6, and the sleeve 7 can slide along the axis of the guide tube 6, and a sleeve 7 is provided on the outer side of the sleeve 7 A first annular block 8 is provided, the first annular block 8 is spaced apart from the sleeve 7 and an elastic spiral plate 9 is provided at the spacing position, the inner end of the spiral plate 9 is fixedly connected to the sleeve 7, the outer end of the spiral plate 9 is fixedly connected to the first annular block 8, the outer end of the first annular block 8 is provided with bristles 10, the outer ends of the bristles 10 are in contact with the inner edge surface of the box body 1, a pull rope 11 is provided on the inner side of the guide tube 6, the left end of the pull rope 11 passes through the right end of the box body 1, bypasses the right end of the guide tube 6, and is fixedly connected to the first annular block 8 through the sleeve 7.

[0019] A blocking block 12 is arranged at the powder adding port 5, a second annular block 13 is arranged at the left end of the blocking block 12, the second annular block 13 is connected to the blocking block 12 through a spring, and a plurality of spherical protrusions are fixed on the right end face of the first annular block 8 and the left end face of the second annular block 13.

[0020] A threading ring 14 is fixed to the upper and lower ends of the sleeve 7 respectively. The pull rope 11 passes through the sleeve 7 and passes through the threading ring 14 to be fixedly connected to the first annular block 8, and the fixing point is not in the same radial direction as the threading ring 14; a pull ring 15 is provided at the left end of the box body 1, and the pull ring 15 is fixedly connected to the pull rope 11 passing through the left end surface of the box body 1.

[0021] The radial cross section of the cavity of the shaking bin 4 is larger than the radial cross section of the box body 1, but the lower end surface of the shaking bin 4 is always flush with the lower end surface of the box body 1; the right end surface of the shaking bin 4 is a conical surface.

[0022] When the toner is used up, it is only necessary to take out the box body 1, and then place the blocking block 12 vertically downward, and manually pull the pull ring 15 upward. The pull ring 15 drives the box body 7 and the first ring block 8 to move downward along the axis of the guide tube 6 synchronously through the pull rope 11. During the movement, the first ring block 8 can clean the inner wall of the box body 1 through the bristles 10 on its outer side until the box body 7 moves to the rightmost end of the guide tube 6. At this time, the second ring block 8 is placed in the shaking bin 4 and contacts with the left end face of the second ring block 13; because the fixing point of the threading ring 14 on the box body 7 and the fixing point of the pull rope 11 on the first ring block 8 are not in the same radial direction, as shown in the figure below Figure 4As shown, continue to pull the pull ring 14, the pull rope 11 can overcome the elastic force of the spiral plate 9 to make the first annular plate 8 rotate relative to the sleeve 7. The principle is consistent with the compression of the spring. During the rotation of the first annular plate 8, the spherical protrusion on its right end face collides with the spherical protrusion on the left end face of the second annular plate 13 to produce a circumferential collision, and an axial collision is generated under the thrust of the compression spring. The vibration generated by the collision can cause the residual carbon powder on the bristles 10 to be shaken off into the shaking bin 4, and then the block 12 is opened to pour out the carbon powder to complete the cleaning operation of the carbon powder box; after cleaning, it is only necessary to push the first annular plate 8 inward into the innermost end of the box body 1 manually or with the help of a long rod to reset it.

[0023] The utility model can effectively prevent carbon powder from sticking to the wall by arranging an axially movable first annular block 8 in the carbon powder box to clean the inner wall of the box body 1. At the same time, the fixing point of the threading ring 14 on the sleeve 7 and the fixing point of the pull rope 11 on the first annular block 8 are not in the same radial direction. After the first annular block 8 moves to the maximum distance, a torsional force is generated under the pulling force of the pull rope 11, which cooperates with the spherical protrusion of the second annular block 13 to generate vibration, so that dust on the bristles 10 falls off, greatly improving the service life and cleaning efficiency of the bristles 10.
