Description

Technical Field

[0001] The invention relates to the technical field of toner cartridges, and in particular to a developer supply device capable of automatically replenishing a developer when the remaining amount is insufficient. Background Art

[0002] The printer device provides developer (toner) through the toner cartridge. The toner cartridge of a general printer is composed of a powder bin, a waste toner bin, a photosensitive drum, a charging roller, a magnetic roller or a developing roller, a powder scraper, a cleaning scraper, a cleaning blade holder, a left end cover and a right end cover. The toner cartridge is combined together to form a toner cartridge, which is installed inside the printer for developing images. With the continuous development of printing and imaging technology, the toner cartridge is a common component of printing equipment. The developer supply inside the toner cartridge is crucial to the printing quality and the normal operation of the equipment. In the traditional developer supply method, it is usually necessary to manually check the remaining developer regularly and replenish it manually. This method is not only inefficient, but also prone to the situation that insufficient developer may affect the printing quality or equipment failure due to human negligence;

[0003] The existing traditional method of replenishing developer is usually manual operation, which requires opening the equipment, replacing the developer box or performing cumbersome replenishment steps. This method is not only inefficient, but also easily introduces impurities such as dust during operation, affecting the quality of the developer and the performance of the equipment. It is also necessary to shut down the printer equipment, take out the toner cartridge inside the printer, open the cover and pour the developer. When the developer is directly poured into the toner cartridge storage position, since the developer is a substance with high environmental requirements, it is easily affected by external factors such as dust and gas, which may reduce the quality of the developer. In the process of replenishing the developer, if the sealing of the developer supply device in the prior art is reduced during the process of replenishing the developer, it is easy to cause problems such as developer leakage and entry of external impurities, affecting the fluidity and stability of the developer as well as the quality of the developer and the reliability of the equipment. Therefore, it is necessary to provide a developer supply device that can automatically replenish when the remaining amount is insufficient, aiming to solve the above problems.

[0016] As a further improvement of the above solution, the outer ring diameter of the sealing gasket is the same as the inner ring diameter of the replenishing material pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the cooperation of the locking link and the locking slide bar, as well as the heart-shaped locking groove design on the movable plate, when the developer is sufficient, the locking slide bar is accurately locked in the heart-shaped recessed position of the locking groove, which plays a role in firmly locking multiple key components. This locking state not only prevents the developer from leaking when it does not need to be replenished, but also effectively prevents the outside gas from entering the system and causing abnormal changes in air pressure, thus ensuring the stability of the internal environment of the developer placement chamber;

[0019] The locking effect of the system is further enhanced by the connection between the arc-shaped locking rod and the movable locking plate. The double locking structure provides a strong safety guarantee for the system, ensuring stability under various working conditions and preventing accidents.

[0020] Compared with the traditional developer replenishing device, this device has the following significant advantages. First, the sensor can accurately detect the remaining developer amount and can trigger the replenishing mechanism in a timely and accurate manner, avoiding insufficient or waste of developer due to inaccurate manual judgment. Secondly, the unique locking and unlocking structure design ensures that when there is no need to replenish the developer, the replenishing box, replenishing material pipe and pipeline are in a completely sealed state, effectively preventing problems such as air pressure entry and developer leakage. Furthermore, the cooperation of compression springs, torsion springs and other components realizes the function of automatic locking and unlocking, which is easy to operate and highly reliable. In the process of replenishing the developer, the synergistic effect of various components makes the whole process smoother and more efficient, greatly improving the convenience and safety of developer replenishment.

[0021] 2. In the unlocked state, the space between the fixed box and the sealed push plate is increased by starting the micro air pump, so that the air pressure in the space between the fixed box and the sealed push plate increases accordingly. With the increase of gas, the gas pushes the sealed push plate to move in the direction of the replenishing tube. The sealed push plate drives the pull plate and the slide plate to slide synchronously in the sealed top plate, and the limit rod is in a stretched state. The movement of the sealed push plate can push the developer between the sealed push plate and the replenishing tube. The developer is continuously replenished into the developer placement chamber through the replenishing tube by the thrust. After the replenishment is completed, the whole is locked to prevent the entry of gas and the leakage of the developer. The inside of the replenishing box is closed to prevent the dust or other substances inside the toner cartridge from entering and causing the developer to be contaminated.

[0022] 3. Compared with the prior art, this solution has obvious advantages. On the one hand, by controlling the air pressure through a micro air pump to push the developer to replenish, it can ensure that the developer replenishment process is stable, continuous and efficient. The traditional replenishment method has the problem of untimely replenishment, and this solution can adjust the air pressure according to actual needs to achieve replenishment. On the other hand, timely locking after replenishment is completed can not only prevent the developer from leaking, but also effectively block the entry of external dust and other impurities, thereby ensuring the purity of the developer. Compared with the problem of loose sealing in traditional devices, this effectively improves the reliability and safety of the developer replenishment system, extends the service life of the developer, and also ensures the stability of printing or imaging quality.

[0050] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0051] In the initial state, the compression spring 611 is in a compressed state, the telescopic shaft of the micro electric gas rod 616 is in a retracted state, the movable locking plate 618 is in the groove of the arc-shaped locking rod 622, the push plate 617 and the movable rod 610 are in a separated state, the pressure plate 615 is at the bottom of the pipeline 702, the tension spring 712 is in an unstretched state, the sealing closing plate 709 is in a vertical state due to the replenishing material pipe 603, the micro air pump 701 is in a closed state, the locking slide bar 606 is in the heart-shaped recessed position of the lock groove 609, and the torsion spring 707 is in a normal torque state.

[0052] When working:

When the push plate 617 pushes the movable rod 610 and the movable plate 608 to move synchronously toward the position of the support plate 604, the locking link 605 rotates on the surface of the support plate 604, and the locking slide bar 606 fixed to the locking link 605 is restricted by the heart shape of the locking groove 609, so that The locking slide bar 606 and the locking link 605 follow the heart-shaped sliding of the locking groove 609, so that the locking slide bar 606 moves from the tip position of the heart-shaped locking groove 609 to the recessed position of the heart-shaped locking groove 609. When the locking slide bar 606 is stuck in the recessed position of the heart-shaped locking groove 609, the locking slide bar 606, the locking link 605 and the moving plate 608 are clamped. At this time, the compression spring 611 is in a compressed state, and the movement of the moving plate 608 drives the mounting frame 619 fixedly connected thereto to move synchronously. The arc-shaped locking rod 622 is kept in place by the fixing frame 621, and the movement of the mounting frame 619 causes the arc-shaped locking rod 622 to move. 2, the movable shaft inside slides in the arc-shaped through groove 620, and when the mounting frame 619 slides, the arc-shaped locking rod 622 rotates around the movable shaft inside the fixing frame 621, so that the end of the arc-shaped locking rod 622 with the groove is clamped on the bottom of the movable locking plate 618, and the position of the movable plate 608 and the movable rod 610 is locked by the clamping force of the arc-shaped locking rod 622 and the movable locking plate 618, and the locking of the movable rod 610 drives the sealing top plate 613 fixedly connected thereto to be locked synchronously, and the locking of the sealing top plate 613 drives the connecting rod 614 and the pressure plate 615 fixedly connected thereto to be locked synchronously, and by The movement of the movable rod 610 causes the sealing top plate 613, the connecting rod 614 and the pressure baffle plate 615 to move synchronously, so that the pressure baffle plate 615 moves to the bottom of the pipe 702. The pressure baffle plate 615 blocks the pipe 702 to prevent the gas from entering and causing the gas pressure to increase when in the locked state, further improving the sealing of the replenishment box 601, ensuring the stability of the internal environment of the developer placement chamber 2, and helping to maintain the quality of the developer. At the same time, the blocking effect of the pressure baffle plate 615 on the pipe 702 and the clamping of the arc-shaped locking rod 622 and the movable locking plate 618 form a double guarantee, thereby improving the reliability of the system.

[0054] The movement of the pressure plate 615 toward the replenishing material pipe 603 can drive the extension rod 703 fixed thereto to move synchronously, and the movement of the extension rod 703 drives the pull rod 710 rotatably connected thereto to move synchronously, and the movement of the pull rod 710 drives the sealing closure plate 709 and the sealing gasket 708 rotatably connected thereto to flip to a vertical state with respect to the replenishing material pipe 603, so that the movable plate 608 and the locking groove 609 close the replenishing material pipe 603, so that the replenishing box 601 is in a closed state as a whole, and the gas can be prevented from entering, and the developer in the replenishing box 601 can be prevented from leaking, and the dust inside the toner cartridge and the gas can be reduced to enter the replenishing box 601 to contaminate the developer, thereby further ensuring the quality of the developer;

[0055] When the sensor inside the developer placement chamber 2 detects that the developer remaining in the developer placement chamber 2 is insufficient, the sensor detects and sends a signal to the controller, and the controller controls the telescopic shaft of the micro-electric gas rod 616 to extend again to drive the push plate 617 and the movable lock plate 618 fixedly connected thereto to push in the direction of the support plate 604, and the movable rod 610 and the movable plate 608 are pushed by the push plate 617 to move when the push plate 617 pushes the movable rod 610 and the movable plate 608 to move, and the locking slide bar 606 moves from the heart-shaped recessed position of the lock groove 609 to the tip of the heart shape under the restriction of the heart-shaped groove of the lock groove 609, and is compressed back by the compression spring 611. The elastic force pushes the movable plate 608 to reset, and at this time the mounting frame 619 follows the movement of the movable plate 608 to rotate the arc-shaped locking rod 622, so that the bottom of the movable locking plate 618 comes out of the groove of the arc-shaped locking rod 622, and the movable plate 608 resets the movable rod 610 to the direction of the micro-electric gas rod 616, and the reset of the movable rod 610 drives the sealing top plate 613 fixedly connected thereto to reset synchronously, and the reset of the sealing top plate 613 drives the connecting rod 614 and the pressure plate 615 fixedly connected thereto to reset, so that the pressure plate 615 is separated from the bottom of the pipe 702, and the pipe 702 is in a state of not being blocked. When the pressure plate 615 is in the blocking state and is separated from the bottom of the pipe 702, the pressure plate 615 drives the extension rod 703 and the pull rod 710 fixedly connected thereto to be pulled synchronously in the direction away from the replenishing material pipe 603, and the sealing gasket 708 and the sealing closing plate 709 are turned over by the pulling force of the pull rod 710, and the torsion spring 707 at this time increases the torsion force, so that the sealing closing plate 709 and the sealing gasket 708 can be opened, and the whole is in the unlocked state at this time, which makes it easier for the developer inside the fixed box 602 to enter the developer placement chamber 2 through the opened replenishing material pipe 603, thereby The developer is replenished in the remaining amount, thereby achieving the unlocking effect, which is convenient for replenishing the developer in the fixed box 602 into the developer placement chamber 2, so that when the remaining amount of the developer is insufficient, it can quickly respond and automatically unlock to prepare for the replenishment of the developer. The efficiency of replenishing the developer is quickly improved through automatic unlocking, which reduces the need for manual intervention and makes the whole process more convenient and intelligent. At the same time, the flip design of the sealing gasket 708 and the sealing closing plate 709 ensures that the replenishing material pipe 603 can be opened in time when the developer needs to be replenished, and the replenishment of the developer will not be hindered due to mechanical failures and other reasons;

[0056] When the movable plate 608 and the locking groove 609 inside the replenishing material pipe 603 are in the unlocked open state, and the pressure plate 615 is detached from the bottom of the pipe 702, the micro air pump 701 is started, and the gas enters the space between the fixed box 602 and the sealing push plate 715 through the pipe 702, so that the air pressure in the space between the fixed box 602 and the sealing push plate 715 increases accordingly. Through the increase of gas, the gas pushes the sealing push plate 715 to move in the direction of the replenishing material pipe 603, and the sealing push plate 715 drives the pulling plate 714 and the sliding plate 713 fixedly connected thereto to slide synchronously in the sealing top plate 613, so that the sealing push plate 715 is pushed in the direction of the replenishing material pipe 603, and the tension spring 712 is in a stretched state at this time, and the movement of the sealing push plate 715 can push the developer between the sealing push plate 715 and the replenishing material pipe 603, and the developer is continuously passed through the replenishing material pipe 603 by the thrust. 03 is replenished into the developer placement chamber 2, so that when the remaining developer inside the toner cartridge is insufficient, the developer is automatically and quickly replenished into the developer placement chamber 2. The start-up of the micro air pump 701 provides power for the developer replenishment, ensuring that the developer can be quickly and stably replenished into the developer placement chamber 2. The push of the sealing push plate 715 pushes the developer into the developer placement chamber 2 more quickly, thereby improving the efficiency and accuracy of replenishment. The stretched state of the tension spring 712 plays a certain buffering role, thereby avoiding the excessive displacement of the sealing push plate 715 or damage to other components during the movement. After the developer is replenished, the replenishment box 601 is locked and closed, thereby ensuring the sealing and safety of the replenishment box 601, preventing the leakage of the developer, and extending the service life of the developer. At the same time, it avoids the contamination of the developer by external dust and other substances, thereby ensuring the quality of the developer, thereby improving the printing or imaging effect.
