Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a developer filling device. Background Technology

[0002] Printer developer storage cartridges, developer tanks, ink cartridges, etc. (hereinafter referred to as containers) have dedicated filling inlets, but these are often blocked by screws or other obstructions, causing developer to easily clog the filling inlet and resulting in uneven filling. Existing filling methods to address this issue include disassembling some assembly parts before filling, which is inefficient and the disassembled parts cannot achieve the original precision, leading to potential abnormalities. Another filling method is to manually fill the developer after the container is placed upright, but this method is prone to spillage and cannot achieve relatively high-precision grammage filling.

[0003] Developer is usually toner, carrier, or mixture in printers. It appears as powder and is typically found in black, cyan, red, and yellow. Utility Model Content

The fixed base is placed on the platform for placing a container. The rotating shaft is placed on one side of the fixed base for connecting with the gear set of the container. The drive motor is used to drive the rotating shaft to rotate, thereby driving the rod assembly inside the container to rotate.

[0012] The rotating shaft is a cylindrical shape with a cross section, so that there is no relative rotation when the rotating shaft is connected to the rotating shaft; the other end of the rotating shaft is connected to the gear set.

[0013] A further technical solution of this utility model is: the drive motor is placed inside the platform, the output end of the drive motor is connected to the rotating shaft through a transmission component, and the drive motor can rotate in both directions and has adjustable speed.

[0014] To save space, the drive motor is installed inside the platform. The forward and reverse rotation of the drive motor is used to adapt to the forward and reverse rotation of the rod assembly inside the container. The speed of the drive motor is adjustable to meet the different needs of both the debugging and working states.

[0015] A further technical solution of this utility model is: the output end of the drive motor is connected to the rotating shaft to drive the rotating shaft to rotate.

[0016] For situations where space is not limited, the drive motor can be mounted above the platform and directly connected to the rotating shaft.

The sealing component is detachably connected to the discharge port, and the connecting component is placed between the discharge port and the feed port of the container.

[0020] After adding developer into the hopper, the sealing components are then removed, allowing the developer in the hopper to enter the container precisely from the discharge port, achieving accurate filling.

[0021] A further technical solution of this utility model is: the sealing component includes a sealing block that cooperates with the discharge port, and the sealing block has a conical structure.

[0022] To prevent the developer from being carried away during the removal of the sealing component, the sealing block is cone-shaped.

[0023] A further technical solution of this utility model is: the base is detachably connected to the platform or the base is connected to the weighing equipment.

[0024] The entire adjustment structure can be installed at any position on the platform via the base, allowing the feed inlet of the hopper to be adapted to the feed inlet of the container. Alternatively, the base can be connected to a weighing device, and the feed inlet will be closed once the amount of developer in the hopper entering the container reaches the set amount.

[0025] The beneficial effects of this utility model are as follows: In this utility model, the container to be filled is removed as a whole and placed on a fixed base for installation and positioning. The drive motor is started, and the rotating shaft is connected to the gear set of the container, thereby realizing the rotation of the drive motor to rotate the rod assembly inside the container, simulating the normal operation of a printer.

Moreover, the container is filled as a whole and does not need to be disassembled, avoiding the inability to restore accuracy after disassembly and reassembly.

[0026] Therefore, this device was designed to improve processing efficiency, ensure accuracy, and save labor. This invention simulates machine operation by naturally filling the developer container through its original powder inlet and outlet. This achieves the goals of not disassembling the components, eliminating the need for vertical placement which could lead to developer leakage, and avoiding concerns about developer spillage causing weight discrepancies during filling.

[0050] The installation of this utility model is as follows: the developer container 5 can be placed at the upper limit of the fixed base 4. The drive motor in the device drives the main transmission gear in the gear set 52 on the container 5 to rotate, and the container 5 simulates the normal working state of the printer. During the rotation, the developer can be poured into the feeding port 51 of the container 5. The developer can be directly poured into the material hopper 10.

[0051] The working principle of this utility model is as follows: First, determine the container 5 to be filled with developer. Select the corresponding adapter 11, fixing base 4, and rotating shaft 3, install and fix them, and adjust their corresponding positions. Then, install the adjustment structure and the material hopper 10. According to the position of the feeding port 51 of the container 5, install the material hopper 10 in the corresponding position. After completion, connect the power supply of the entire device.

[0052] Confirm the flow state of the developer in the corresponding container 5, determine the rotation direction of the motor rotation adjustment knob 12 according to the flow state, and reduce the initial rotation speed adjustment knob 14 for the experiment.

[0053] Install container 5 onto the fixed base 4. The main drive gear in gear set 52 on container 5 and the rotating shaft 3 are matched. After weighing, the developer is poured into the hopper 10. The drive motor power switch 13 is turned on, and the hopper sealing assembly 8 is pulled up. At this time, the motor speed adjustment knob 14 is slowly adjusted to increase the rotation speed, facilitating the smooth entry of the developer into container 5. After the developer is poured into hopper 10, the motor switch is turned off, and container 5 containing the developer is removed. The next container is then filled with developer.

The container used in this example is a Ricoh MP6054 developing chamber; however, this device can also be adapted to other containers. By developing this equipment, the need for manually disassembling the top cover or manually rotating the gears to slowly add developer has been eliminated. This significantly reduces labor intensity and improves production efficiency. The shift from manual to semi-automatic addition has proven effective in practical use. The filling accuracy has been reduced from an error of over 10g manually to within 2g.

[0055] This device has passed testing and is working well in the processing workshop, meeting the existing enterprise standards. Furthermore, by modifying the corresponding adapter 11, rotating shaft 3, and fixing base 4, this device can be used to fill containers 5 of different sizes with developer. After testing, adjustments, and improvements, it can be used on multiple products, significantly improving the device's utilization rate.
