Description

Technical Field

[0001] The present invention relates to the technical field of printer toner cartridges, and in particular to an intelligent structure for increasing the printing volume of toner cartridges and reducing internal wear. Background Art

[0002] At present, the performance of the toner cartridge, as one of the core components of the printer, directly affects the printing quality and efficiency. In the existing toner cartridge structure, the amount of toner delivered from the raw material bin to the developer bin during operation is relatively fixed and cannot be dynamically adjusted according to the needs of the actual printing task. For example, when printing complex images or text, a higher toner concentration is required to ensure the printing quality, but since the toner flow cannot be increased in time, the printed image or text may be lighter in color and lack clarity, affecting the printing effect; when printing simple documents, excessive toner delivery not only causes waste, but also increases the wear inside the toner cartridge and shortens the service life of the toner cartridge.

[0003] Secondly, since the toner flow cannot be precisely controlled, in some cases, toner may accumulate excessively or be washed at high speed in certain parts of the toner cartridge, especially at the connection between the toner supply pipe and the developer bin and near the developer magnetic roller and other parts. This uneven toner flow and accumulation will aggravate the wear of the internal parts of the toner cartridge, such as the wear of the inner wall of the toner supply pipe and the scratches on the surface of the developer roller. In the long run, it will cause the performance of the toner cartridge to gradually decline, resulting in unstable print quality, toner leakage and other problems, which will increase the user's usage cost and maintenance frequency.

[0004] Finally, the uncontrollable toner flow and internal wear problems further limit the print volume of the toner cartridge. On the one hand, it is impossible to optimize the use of toner according to the actual situation, resulting in insufficient use of toner. When the toner cartridge has not yet reached its theoretical print volume, it may need to be replaced because the print quality cannot meet the requirements; on the other hand, excessive wear of internal components will affect the overall performance and stability of the toner cartridge, so that after a period of use, even if there is still toner remaining, the toner cartridge may not be able to continue to work normally due to damage to other components, thereby reducing the actual print volume of the toner cartridge.

[0005] Therefore, there is an urgent need for an intelligent structure that can increase the printing volume of the toner cartridge and reduce internal wear. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Embodiment 1 like Figure 1 As shown, the smart structure provided by the present invention is applied to a toner cartridge, and its principle is: Toner storage and stirring: Raw material bin 1 is used to store toner and is the source of toner supply for the entire toner cartridge. Stirring rod 2 continuously stirs toner in raw material bin 1 to prevent toner from agglomerating due to long-term standing, ensuring that toner can flow evenly to the toner supply channel, providing a stable toner supply for the subsequent development process.

[0024] Toner delivery and development: The small intelligent regulating valve 9 is installed on the powder supply pipeline between the raw material bin 1 and the developing bin 3, and plays a key role in controlling the toner flow. It can accurately adjust the amount of toner delivered from the raw material bin 1 to the developing bin 3 according to the needs of the printing task through the cooperation of the brake mechanism and the valve core assembly 14. For example, when printing complex images or texts, which requires a higher toner concentration, the intelligent structure will increase the opening and increase the toner flow; while when printing simple documents, it will reduce the opening and reduce the toner flow, which not only ensures the printing quality, but also avoids toner waste and excessive wear inside the toner cartridge.

[0025] The developing bin 3 is a place where the toner is developed. A developing magnetic roller 4 is arranged inside the developing magnetic roller 4, which adsorbs the toner delivered from the raw material bin 1 onto its surface through electrostatic adsorption to form a uniform toner layer, preparing for the next step of imaging.

[0026] Imaging process: The imaging drum 5 is one of the core components of the toner cartridge. During the printing process, an electrostatic latent image is formed on the surface of the imaging drum 5 according to the printing content. When the developing magnetic roller 4 with toner comes into contact with the imaging drum 5, the toner on the developing magnetic roller 4 is transferred to the electrostatic latent image of the imaging drum 5 due to the static electricity, thereby developing the electrostatic latent image into a visible toner image.

[0027] Charging and cleaning: A main charging roller 6 is provided on one side of the imaging drum 5. Before imaging, the main charging roller 6 will evenly charge the surface of the imaging drum 5, so that the surface carries a certain charge, laying the foundation for the formation of an electrostatic latent image. In addition, a cleaning blade 7 is provided. After the imaging drum 5 completes a printing task, some toner that has not been transferred to the paper will remain on the surface. The cleaning blade 7 will scrape off the residual toner and make it fall into the waste bin 8, keeping the surface of the imaging drum 5 clean for the next imaging process.

[0028] Based on the above, refer to Figure 2 This embodiment provides an intelligent structure for increasing the printing volume of the toner cartridge and reducing internal wear. It is arranged between the raw material bin 1 and the developing bin 3. It is a key control component in the entire toner cartridge toner conveying process, and plays a role in accurately adjusting the toner flow, thereby increasing the printing volume of the toner cartridge and reducing internal wear. The intelligent structure is a small intelligent regulating valve 9, which is arranged on the powder supply pipeline of the raw material bin 1. The small intelligent regulating valve 9 is composed of a sealing component, a brake mechanism and a valve core component 14. The sealing components are arranged at both ends of the small intelligent regulating valve 9, the valve core component 14 is arranged in the middle of the two sets of sealing components, and the brake mechanism is arranged above the valve core component 14.

[0029] Wherein, the sealing assembly includes a first sealing mounting plate 10 and a second sealing mounting plate 11, the first sealing mounting plate 10 and the second sealing mounting plate 11 are symmetrically arranged, the first sealing mounting plate 10 is connected to one end of the powder supply pipeline by bolts, and the second sealing mounting plate 11 is connected to the other end of the powder supply pipeline by bolts. The contact surface where the first sealing mounting plate 10 is connected to the powder supply pipeline and the contact surface where the second sealing mounting plate 11 is connected to the powder supply pipeline are both provided with high temperature wear-resistant rubber sealing rings to ensure the sealing performance of the intelligent structure. The middle parts of the first sealing mounting plate 10 and the second sealing mounting plate 11 are both through-type structures, and the through-portion of the first sealing mounting plate 10 is connected to the through-portion of the second sealing mounting plate 11 to form a carbon powder flow channel, the inner wall of the carbon powder flow channel is polished, and its surface is smooth to reduce the flow resistance and wear of the carbon powder, and a valve core assembly 14 is installed at the carbon powder flow channel.

[0030] like Figure 4As shown, the valve core assembly 14 includes a valve core rod 20 and a valve core 21. The valve core 21 is a spherical wear-resistant ceramic material, and the valve core 21 is arranged inside the carbon powder flow channel and is clearance-matched with the carbon powder flow channel to ensure that the valve core 21 can rotate flexibly; the valve core rod 20 and the valve core 21 are fixedly connected by threaded connection, and the thread is coated with anti-loosening fastening glue to ensure the stability of the connection between the valve core 21 and the valve core rod 20 during long-term use. The valve core rod 20 is used to control the powder supply flow of the toner cartridge, and the top of the valve core rod 20 is connected to the brake mechanism through the coupling 16.

[0031] The brake mechanism includes a drive unit 12, which is a small DC motor or a stepper motor. The output shaft of the drive unit 12 is connected to one end of the coupling 16, and the control end of the drive unit 12 establishes a signal transmission link with the control system of the toner cartridge through the Wi-Fi wireless protocol. The control system of the toner cartridge calculates the required toner flow rate through a built-in algorithm based on factors such as the complexity of the printing task (such as the printed page coverage, printing speed, etc.), the current printing volume, and the remaining toner in the toner cartridge, and sends the corresponding control signal to the drive unit 12. The control signal includes parameters such as the speed and direction of the motor. The drive unit 12 accurately controls the opening of the valve core 21 according to the received signal, thereby achieving precise adjustment of the toner flow rate to achieve the purpose of increasing the printing volume and reducing internal wear. For example, when the printing task is complex and the page coverage is high, the control system will send a signal to speed up the drive unit 12, increase the opening of the valve core 21, and increase the toner flow rate; conversely, when the printing task is simple, reduce the opening of the valve core 21 and reduce the toner flow rate.

[0032] like Figure 3As shown, the coupling 16 includes two sets of driving shafts 17 and connecting slots 18. The connecting slots 18 are arranged in the middle of the two sets of driving shafts 17, and a valve core rod 20 is installed inside the connecting slots 18. The two sets of driving shafts 17 are arranged in parallel and symmetrically. The inner sides of the two sets of driving shafts 17 are provided with cylindrical connecting slots 19 for connecting the output shaft of the driving unit 12. A circular sealing cover 15 is also provided below the coupling 16. The circular sealing cover 15 is installed on the top of the valve core assembly 14 through a movable bolt. A flow sensor 13 is provided at one end of the bottom of the circular sealing cover 15. The flow sensor 13 is installed at the toner flow channel between the valve core assembly 14 and the first sealing mounting plate 10 to monitor the toner flow. The flow sensor 13 and the control system of the toner cartridge transmit signals through the Wi-Fi wireless protocol. The flow sensor 13 monitors the toner flow in real time and feeds back the data to the control system. When the flow sensor 13 detects that the toner flow is abnormal, the control system will adjust the action of the driving unit 12 according to the feedback signal. For example, if the flow is too large, the control system will send a signal to reduce the rotation speed of the drive unit 12, reduce the opening of the valve core 21, and reduce the toner flow; if the flow is too small, the opening of the valve core 21 will be increased to increase the toner flow to ensure that the toner flow is stable within an appropriate range, thereby ensuring the normal operation of the toner drum and a steady increase in print volume.

[0033] Therefore, by using the above-mentioned intelligent structure for increasing the printing volume of the toner cartridge and reducing internal wear, the valve core opening can be accurately adjusted according to factors such as the complexity of the printing task, the current printing volume and the remaining toner, by utilizing the cooperation of the braking mechanism (such as a small DC motor or a stepper motor) and the valve core assembly (including the valve core rod and the spherical valve core), and the signal transmission link established with the toner cartridge control system through the Wi-Fi wireless protocol, so as to achieve dynamic control of the toner flow. When printing complex content, the toner flow is increased in time to ensure the printing quality; when printing simple content, the toner flow is reduced to avoid waste and excessive wear, improve the toner utilization rate, and thus increase the printing volume of the toner cartridge; and it also avoids excessive accumulation and high-speed flushing of toner inside the toner cartridge, so that the toner flows more smoothly and evenly in the powder supply pipeline and the developing bin, thereby effectively reducing the wear on the internal components of the toner cartridge, extending the service life of the toner cartridge, and reducing the printing quality problems and maintenance costs caused by wear.
