[0022] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] Reference Figures 1 to 4 The present application provides an automatic carrier toner separation device, which includes a separation channel 1 with a roller brush 3 for frictional separation of toner and carrier; the two ends of the roller brush 3 are fixed by bearings 4; the bearings 4 are configured to be quick-disassembly structure to facilitate replacement of the roller brush.

[0024] The separation channel 1 is equipped with a roller brush 3 for frictional separation of toner and carrier; the two ends of the roller brush 3 are fixed by bearings 4; the bearings 4 are configured with a quick-disassembly structure to facilitate the replacement of the roller brush 3; the quick-disassembly structure includes snap-fit ​​or threaded connectors to achieve quick installation and removal of the bearings 4.

[0025] Furthermore, a pressure sensor is installed on the inner ring of the bearing 4 connected to the roller brush 3 and connected to the controller; the controller dynamically adjusts the rotation speed or pressure of the roller brush 3 according to the sensor signal. The automatically adjustable roller brush pressure control solves the problem of separation efficiency fluctuations caused by changes in the carrier / toner ratio, avoids excessive friction or incomplete separation, improves separation accuracy, and extends the roller brush life.

[0026] A removable filter screen is added to the inlet of the toner collection section 12; the filter screen is connected to the toner collection section via a magnetic or snap-fit ​​structure. This prevents large particles of impurities from entering the collection section and causing blockage, optimizing the quality of subsequent toner recovery. It simplifies the maintenance process and adapts to recovery scenarios with different purity requirements. A micro-pore array is set on the sidewall of the separation channel 1; the pores are connected to an external air pump, enhancing the separation effect between the carrier and toner through pulsed airflow. This addresses the toner adhesion problem in high humidity environments, reduces the roller brush load, and reduces energy consumption.

[0027] As an example, such as Figure 1 and Figure 4 As shown, an automatic carrier toner separation device includes a separation channel 1, a carrier collection section 2, a roller brush 3, and a toner collection section 12. The separation channel 1 and the roller brush 3 are located between the carrier collection section 2 and the toner collection section 12. A fixing block 5 is fixedly connected to the side of both the carrier collection section 2 and the toner collection section 12 near the roller brush 3. A connecting block 6 is tightly fitted to one side of the fixing block 5. The connecting block 6 contains a positioning component 7 and a fixing component 9. The fixing component 9 includes a sliding plate 91, a fixing rod 92, a connecting rod 93, and a second spring 94. A sliding groove 10 and a recess 11 are formed within the connecting block 6, and a sliding connection is made within the recess 11. There is a sliding plate 91, and connecting rods 93 are fixedly connected to the upper and lower sides of the sliding plate 91. A fixing rod 92 is fixedly connected to one side of the sliding plate 91, and a second spring 94 is provided on the other side of the sliding plate 91. The outer ring of the bearing 4 is fixedly connected to one side of the connecting block 6. One end of the roller brush 3 is fixedly connected to the inner ring of the bearing 4, which is rotatably connected to the outer ring of the bearing 4. The fixing component 9 makes it easy to disassemble and assemble the roller brush 3, so as to facilitate the replacement of the roller brush 3 with severe bristle wear after long-term use. The positioning component 7 provides a positioning effect when the roller brush 3 is installed, so as to facilitate the insertion of the fixing rod 92 into the fixing block 5.

[0028] The slide groove 10 and the groove 11 are connected. The connecting rod 93 and the slide groove 10 are slidably connected, which facilitates the movement of the connecting rod 93. The fixing rod 92 is inserted into the fixing block 5. The second spring 94 is set between the sliding plate 91 and the inner wall of the groove 11, which facilitates the use of the fixing rod 92. The positioning component 7 includes a locking block 71, a first spring 72 and a moving plate 73. A limiting groove 8 is opened in the connecting block 6 to facilitate the positioning of the roller brush 3 during installation. The moving plate 73 is slidably connected in the limiting groove 8. A hemispherical locking block 71 is fixedly connected to one side of the moving plate 73. The first spring 72 is provided between the other side of the moving plate 73 and the inner wall of the limiting groove 8. One side of the locking block 71 is tightly fitted with the recess of the fixing block 5, which facilitates the use of the locking block 71.

[0029] During operation, the device is powered by an external power source. When using the automatic carrier toner separation device, first place the entire device in a suitable position. For the specific usage of the separation channel 1, carrier collection section 2, and toner collection section 12, refer to the automatic carrier toner separation device disclosed in patent publication number CN220419803U. At the end of the separation channel 1 is a roller brush 3. The roller brush 3 can rotate between two connecting blocks 6 under the action of the bearing 4. The resulting friction further separates the toner and carrier. When the brush bristles of the roller brush 3 are severely worn after prolonged use, it needs to be replaced. The user holds the connecting rod 93 and moves it towards the roller brush 3 within the sliding groove 10 opened in the connecting block 6. The connecting rod 93 drives the sliding plate 91 and the fixed rod 92 to move in the same direction. The second spring 94 is under pressure and in a compressed state until the fixed rod 92 is fully compressed. Move the brush 3 away from the fixing block 5. At this time, the fixing rod 92 moves into the groove 11 opened in the connecting block 6. Control the fixing rod 92 at the other end of the roller brush 3 to move into the groove 11 in the same way. At this time, you can hold the roller brush 3 and move it forward as a whole. During the forward movement, the locking block 71 is compressed, which drives the moving plate 73 and the locking block 71 to move completely into the limiting groove 8 opened in the connecting block 6. The first spring 72 is compressed until the roller brush 3 is moved forward as a whole and then taken out. Then place the new roller brush 3 between the two fixing blocks 5 and move it from front to back. Hold the connecting rod 93 and control the fixing rod 92 to move completely into the groove 11 until the locking block 71 and the recess of the fixing block 5 are tightly fitted. Release the connecting rod 93. Under the action of the elastic force of the second spring 94, the fixing rod 92 is inserted into the fixing block 5 to effectively fix the installed roller brush 3 and complete the replacement of the roller brush 3.
