As shown in fig. 1, fig. 2 and fig. 3, the developer supply container provided in this embodiment includes a rotary container 1 for conveying a developer and an intermittent regulator 2 for intermittently supplying gas into the rotary container 1 and regulating the internal pressure of the rotary container 1, the rotary container 1 has dual functions of conveying and storing the developer, a powder outlet box 3 is disposed at one end of the rotary container 1, a part of the internal space of the powder outlet box 3 forms an air mixing space 31 for accommodating the developer, a powder outlet 32 for flowing out the developer is disposed at the bottom of the powder outlet box 3, the powder outlet 32 is located below the air mixing space 31, and the powder outlet 32 is also located at the bottom of the powder outlet box 3. The developer is conveyed to the air mixing space 31 in the powder outlet box 3 under the rotation action of the rotary container 1, meanwhile, the intermittent regulator 2 intermittently supplies a fixed amount of gas to the air mixing space 31, and after the fixed amount of gas is mixed with the developer, the developer in the air mixing space 31 flows out from the powder outlet 32 along with the outflow of the fixed amount of gas. Because the intermittent regulator 2 can periodically provide a fixed amount of gas to the gas mixing space 31, the fixed amount of gas can effectively ensure that the gas pressure inside the developer supply container is stable, and the phenomenon that the gas pressure inside the developer supply container is too high or too low as a pump is adopted is avoided, because the pump charging and discharging gas has insurmountable hysteresis, the developer is ensured not to be in an excessive compaction state, namely, the phenomenon of material burst is avoided, and the high precision of the developer supply amount is realized. Compared with the prior art, the intermittent regulator 2 in the present embodiment can intermittently supply a fixed amount of gas, and the intermittent period and the supply amount of gas in the prior art are difficult to control, which easily causes the developer to be compacted.

As shown in fig. 1, 2 and 3, in order to facilitate the developer in the rotary container 1 to flow into the powder outlet box 3, the rotary container 1 further includes a connecting cylinder 11 and a containing barrel 12, one end of the connecting cylinder 11 is rotatably connected to one end of the powder outlet box 3, and the other end of the connecting cylinder 11 is screwed to the containing barrel 12. The setting of connecting cylinder 11 has effectively connected out powder box 3 and has held bucket 12, and connecting cylinder 11 also is favorable to the installation to stir the board subassembly simultaneously. As shown in fig. 8, the paddle assembly is composed of a first paddle 41, a second paddle frame 42, and a third paddle 43 hereinafter. Connecting cylinder 11 with hold bucket 12 and pass through threaded connection even as an organic whole after, when connecting cylinder 11 and hold bucket 12 rotatory, can make the continuous flow of developer to go out powder box 3 to guarantee going out the continuous supply of the interior developer of powder box 3.

As shown in fig. 3, 5, 6, and 7, in order to facilitate the intermittent actuator 2 to perform a stable reciprocating motion and obtain power from the stirring plate assembly, further, the intermittent actuator 2 includes a cam piston 21 having a cam surface 211, one end of the connecting cylinder 11 is provided with a first stirring plate 41, an end surface of one end of the first stirring plate 41 is in contact with the cam surface 211 of the cam piston 21, when the first stirring plate 41 rotates, the first stirring plate 41 drives the cam piston 21 to perform a reciprocating translation along the inner wall of the outlet box 3, similar to the principle of a worm gear structure, but in this embodiment, the first stirring plate 41 only rotates, and due to the unevenness of the cam surface 211, the cam piston 21 performs a reciprocating translation along the inner wall of the outlet box 3. In order to power the intermittent adjuster 2, the cam piston 21 is driven to make reciprocating translation along the inner wall of the toner cartridge 3 by the first stirring plate 41, and the first stirring plate 41 is rotatable with the connecting cylinder 11 to constantly push the cam piston 21 to make reciprocating movement. Further preferably, the intermittent regulator 2 further includes a spring 22, the cam surface 211 is located on one side of the cam piston 21, the other side of the cam piston 21 is provided with at least one sliding rod 23, the other end of the powder discharging box 3 is provided with a box cover 33, the inner wall of the box cover 33 is provided with a sliding column 24 corresponding to the sliding rod 23, one end of the sliding rod 23 is inserted into the sliding groove 114 inside the sliding column 24, the sliding rod 23 is in sliding fit with the sliding column 24, the spring 22 is sleeved on the sliding column 24, one end of the spring abuts against the box cover 33, and the other end of the spring abuts against the other side wall of the cam piston 21. Preferably, two sliding rods 23 are arranged on the other side of the cam piston 21, two sliding columns 24 are arranged on the inner wall of the box cover 33, and the two sliding rods 23 and the two sliding columns 24 can effectively ensure stability, although the number of the sliding rods 23 and the sliding columns is three, four or other numbers. Because the first stirring plate 41 only rotates and does not generate axial displacement, the cam piston 21 needs to be reset under the action of the spring 22 after the axial displacement occurs, otherwise the end part of the first stirring plate 41 is not always attached to the cam surface 211, the resetting action of the spring 22 effectively ensures the smooth reciprocating motion of the cam piston 21, in addition, the sliding rod 23 and the sliding column 24 also have a guiding action, the stability and the reliability of the reciprocating motion process of the cam piston 21 are further ensured, and the possibility of the offset of the reciprocating motion of the cam piston 21 is reduced.
