Description

Technical Field

[0001] The invention relates to the technical field of powder filling, in particular to a powder filling machine for a copier ink cartridge. Background Art

[0002] A copier is an office device that can quickly copy the contents of original materials such as paper documents and pictures onto new paper through optical, electrostatic or digital technology. Its basic working principle is usually to scan the original document first, then transfer the image information to the target paper through media such as toner and carbon powder and fix it to the target paper, and finally output a copy that is consistent with the content of the original. After the toner in the copier is produced, it must first be filled in the ink cartridge. When filling the ink cartridge, the ink cartridge is placed on the pressure sensor on the support table of the filling machine, and the powder outlet pipe is located at the opening of the ink cartridge. Start the filling machine, and the toner will flow into the ink cartridge.

[0003] However, due to the extremely small diameter of toner particles, during the process of filling large quantities of ink cartridges, toner falls from the powder outlet of the filling machine to the bottom of the ink cartridge, which can easily cause the fine toner to be stirred up and scattered into the air from the opening of the ink cartridge, polluting the working environment. In the prior art, a dust collection pipeline is usually set around the filling machine for treatment, but in actual use, it is found that the scattered toner near the powder outlet is difficult to be effectively adsorbed, and setting the dust collection pipeline close to the powder outlet will affect the accurate weighing of the toner. Being in such a harsh working environment for a long time will cause potential harm to the health of personnel. Therefore, the present application provides a toner filling machine for copier cartridges to solve the above problems. Summary of the Invention

[0004] The invention provides a toner filling machine for a copier ink cartridge to solve the problem that toner is scattered in the air and causes potential harm to the health of on-site operators.

After the toner filling is completed, the shell is moved upward and the sealing plate is closed.

[0006] Preferably, the outer shell and the inner shell, as well as the inner shell and the movable tube are fixedly connected via a plurality of connecting rods.

[0007] Preferably, the surface of the movable tube is provided with a top ring, which is fixed to the top of the outer shell, the inner shell and the guide cover. The bottom of the outer shell and the inner shell are threadedly connected with a bottom ring. A guide sleeve is fixed on the top of the top ring. An L-shaped guide rod is fixed on the surface of the powder outlet pipe, and the L-shaped guide rod is movably inserted in the guide sleeve.

[0008] Preferably, the outer shell consists of a vertical part 1 and an inclined part 1, the inner shell consists of a vertical part 2 and an inclined part 2, the bottom ring is threadedly connected to the bottom of the inclined part 1 and the inclined part 2, and the through hole 1 is opened on the inner wall of the vertical part 2.

[0009] Preferably, a filter core is installed between the outer shell and the inner shell, the lowest point of the filter core is higher than the highest point of the through hole 1, and the inner side of the filter core is lower than the outer side.

[0010] Preferably, a drawstring is fixed to the top of the sealing plate, and the drawstring is movably passed through the top ring of the pipe and fixed to the surface of the powder outlet pipe.

[0011] Preferably, a sealing ring is fixed to the inner wall of the inner shell, and there is a gap between the bottom of the sealing ring and the top of the ink cartridge.

[0012] Preferably, a slope is provided on the top of the sealing ring, and the slope is used to guide the toner to fall into the ink cartridge.

[0013] Preferably, an L-shaped connecting rod is fixed to the surface of the powder discharge pipe, a mounting seat is fixed to the bottom of the L-shaped connecting rod, the bottom of the mounting seat and the bottom of the powder discharge pipe are in the same plane, a contact sensor is fixed inside the mounting seat, and several vibrators are fixed on the top of the top ring. The contact sensor is electrically connected to the vibrator. After the powder filling is completed, the outer shell moves upward, the sealing plate is attached to the surface of the frame one, and the contact sensor contacts the top ring. At this time, the contact sensor triggers the vibrator to start.

[0014] Preferably, a magnetic ring is fixed inside the mounting seat. After powder filling is completed, the outer shell moves upward and the magnetic ring is magnetically attracted to the surface of the top ring.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a protective component and a suction machine, when working, the shell is moved downward and the shell is covered on the top of the ink cartridge, the sealing plate will be attached to the second through hole, the suction machine is started, and negative pressure is formed at the through hole. The scattered toner is guided by the guide cover, so that the toner smoothly enters the storage cavity from the through hole one, avoiding the toner from floating in the air and protecting the health of the operator. After the powder filling is completed, the shell is moved upward and the sealing plate is attached to the through hole one to avoid the toner from floating out from the through hole one. The toner will be stored in the storage cavity, realizing the collection of the toner and avoiding toner waste.

[0016] By setting up frame one and frame two, the opposite sides of frame one and frame two are both planar structures, which enables the sealing plate to form a tighter sealing effect when it is attached to frame one or frame two. Among them, frame one is made of magnetic material. When the sealing plate is attached to the sealing ring of frame one, the magnetic adsorption effect can be used to stably achieve the closure of the frame one position.

[0017] By providing the inclined portion 1 and the inclined portion 2, the inclined portion 1 and the inclined portion 2 increase the space of the storage cavity, so that the storage cavity can accommodate more toner.

[0018] By setting up a filter element, the toner in the air can be effectively filtered out through the filter element, thereby preventing the toner from entering the interior of the suction machine. The inner side of the filter element is low and the outer side is high, so that the toner gathers on the outside of the filter element, effectively preventing the toner from completely covering the surface of the filter element and causing the filtering performance to decline, thereby extending the service life of the filter element. At the same time, since the toner gathers on the outside of the filter element, when the toner falls downward, it can also prevent it from falling into the through hole, preventing the toner from falling from the through hole when it is used next time.

[0019] By setting up a vibrator and a contact sensor, after the powder filling is completed, the shell moves upward, the top ring contacts the contact sensor, and the contact sensor is triggered to start the vibrator. The vibrator can shake the toner on the filter element off and store the toner at the bottom of the storage cavity, thereby ensuring the filtration performance of the filter element.

[0022] The following describes in detail a toner filling machine for a copier cartridge provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known techniques. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0023] like Figures 1-8 As shown, an embodiment of the present invention provides a powder filling machine for a copier ink cartridge, comprising a powder filling machine body 1 and a powder outlet pipe 2 installed at a powder outlet of the powder filling machine body 1. A support platform is provided on the powder filling machine body 1 and below the powder outlet pipe 2. A pressure sensor is installed on the top of the support platform. The pressure sensor is used to detect whether the toner amount in the ink cartridge meets the standard. A limit ring is also fixed around the pressure sensor for positioning the ink cartridge so that the ink cartridge is in the same position each time it is placed. The invention also includes: The protective component 4 includes a movable tube 21 movably plugged into the bottom of the powder discharge pipe 2, and a guide cover 13 is provided on the surface of the movable tube 21. The guide cover 13 is funnel-shaped, and an inner shell 8 is provided on the outer side of the guide cover 13. An outer shell 5 is provided on the outer side of the inner shell 8. A plurality of through holes 11 are provided on the inner wall of the inner shell 8. A frame 12 is fixed at the inner wall of the inner shell 8 corresponding to the through holes 11. The frame 12 is a magnetic frame. A sealing ring is provided around the frame 12. A plurality of through holes 14 are provided on the outer wall of the guide cover 13 corresponding to the through holes 11. A frame 2 15 is fixed at the outer wall of the guide cover 13 corresponding to the through holes 2 14. A sealing plate 32 is rotatably connected to the top of the frame 12. A storage chamber 17 is formed between the outer shell 5 and the inner shell 8. The facing sides of the frame 12 and the frame 2 15 are both flat. A suction machine 3 is fixed to the powder filling machine body 1, and the suction machine 3 is connected to the upper part of the storage chamber 17 through a pipeline. During operation, the housing 5 is moved downward, the sealing plate 32 is opened, the suction machine 3 is started, and the toner scattered from the ink cartridge port enters the storage chamber 17 from the through hole 11. After the powder filling is completed, the housing 5 is moved upward, the sealing plate 32 is closed, and the movable tube 21 can move with the protective component 4 to ensure accurate docking with the ink cartridge during powder filling; the funnel-shaped guide cover 13 can guide the scattered toner to move along the outer wall of the guide cover 13 toward the through hole 11, and cooperate with the negative pressure formed by the suction machine 3 in the storage chamber 17 to allow the scattered toner to enter the storage chamber 17 smoothly. , to avoid toner leakage and contamination of the working environment, the plane design of frame 12 and frame 2 15 allows the sealing plate 32 to fit more tightly, and the magnetic frame 12 can absorb the sealing plate 32. When filling powder, the sealing plate 32 can be rotated to fit with frame 2 15 and open the through hole 11 to collect the scattered toner. After the powder filling is completed, the sealing plate 32 fits with frame 12 again and closes the through hole 11 to prevent the toner in the storage chamber 17 from leaking, thereby realizing toner collection and protection. The whole process only requires moving the shell 5 up and down, and the operation is convenient and quick.

[0024] like Figure 3 As shown, in this embodiment, the outer shell 5 and the inner shell 8, as well as the inner shell 8 and the movable tube 21, are fixedly connected by a plurality of connecting rods 16. The connecting rods 16 fix the outer shell 5, the inner shell 8 and the movable tube 21 as a whole, ensuring that other components move synchronously when the outer shell 5 is moved, avoiding relative displacement affecting the powder filling and toner collection accuracy. At the same time, the connection method of the connecting rods 16 does not block the through hole 11 and the storage cavity 17, ensuring smooth flow of toner and enhancing the structural stability of the protective component 4.

[0025] like Figure 3As shown, in this embodiment, the surface of the movable tube 21 is provided with a top ring 18, and the top ring 18 is fixed on the top of the outer shell 5, the inner shell 8 and the guide cover 13. The outer shell 5 and the bottom of the inner shell 8 are threadedly connected with a bottom ring 19. A guide sleeve 31 is fixed on the top of the top ring 18, and an L-shaped guide rod 30 is fixed on the surface of the powder outlet pipe 2. The L-shaped guide rod 30 is movably inserted in the guide sleeve 31. The top ring 18 and the bottom ring 19 further strengthen the connection between the outer shell 5, the inner shell 8 and other components. The bottom ring 19 is threadedly connected to facilitate disassembly and cleaning of the toner in the storage chamber 17. The L-shaped guide rod 30 cooperates with the guide sleeve 31 to limit the moving direction of the protective component 4, ensuring that the inner shell 8 is located directly above the ink cartridge to avoid deviation causing powder filling dislocation or toner leakage.

[0026] like Figure 3 As shown, in this embodiment, the outer shell 5 is composed of a vertical part 16 and an inclined part 17, the inner shell 8 is composed of a vertical part 29 and an inclined part 210, the bottom ring 19 is threadedly connected to the bottom of the inclined part 17 and the inclined part 210, and the through hole 11 is opened on the inner wall of the vertical part 29. The inclined part 17 and the inclined part 210 increase the volume of the storage chamber 17, which can accommodate more collected toner and reduce the cleaning frequency. The inclined structure can also guide the collected toner to gather in the direction of the bottom ring 19, which is convenient for subsequent removal of toner from the bottom ring 19 and reduces residue. The through hole 11 of the vertical part 29 is positioned in contact with the guide cover 13 to improve the toner collection efficiency.

[0027] like Figure 3 As shown, in this embodiment, a filter element 22 is installed between the outer shell 5 and the inner shell 8. The lowest point of the filter element 22 is higher than the highest point of the through hole 11. The inner side of the filter element 22 is low and the outer side is high. The filter element 22 can filter the air entering the suction machine 3 to prevent toner from damaging the suction machine 3. The design of the low inner side and the high outer side allows the toner to gather to the outside along the inclined filter element 22 under the action of suction and then fall, avoiding clogging the filter element surface and extending the service life of the filter element. The filter element 22 is positioned higher than the through hole 11 to prevent the collected toner from flowing back to the through hole 11, thereby ensuring stable toner storage.

[0028] like Figure 3 As shown, in this embodiment, a pull rope 20 is fixed on the top of the sealing plate 32, and the pull rope 20 is movable through the top ring 18 and fixed to the surface of the powder outlet pipe 2. In the initial state, the sealing plate 32 is adsorbed on the surface of the frame 12. When the shell 5 is moved downward, the sealing plate 32 is pulled by the pull rope 20, driving the sealing plate 32 to flip and detach from the frame 12, opening the through hole 11; then when the shell 5 is moved upward, the pull rope 20 is relaxed, and the sealing plate 32 naturally falls and fits the frame 12 to close the through hole 11. The shell 5 moves up and down in coordination with the pull rope 20, which can realize automatic linkage control of the sealing plate 32 without additional operation, thereby improving convenience.

[0029] like Figure 3 and Figure 7As shown, in this embodiment, a sealing ring 23 is fixed to the inner wall of the inner shell 8. When filling powder, the outer shell 5 is pulled to drive the inner shell 8 and the sealing ring 23 to move down to the top of the ink cartridge, so that the inner shell 8 covers the ink cartridge opening (such as Figure 3 As shown in the figure, the sealing ring 23 can prevent toner from escaping from the gap between the inner shell 8 and the ink cartridge. At the same time, there is a certain gap between the bottom of the sealing ring 23 and the top of the ink cartridge. The gap is set to prevent the protective component 4 from contacting the ink cartridge and affecting the weighing of the ink cartridge, thereby ensuring the accuracy of the weight of the ink cartridge after filling with powder.

[0030] like Figure 7 As shown, in this embodiment, a slope 24 is provided on the top of the sealing ring 23. The slope 24 is used to guide the toner to fall into the ink cartridge. The slope 24 can guide the toner splashed on the sealing ring 23 into the ink cartridge, avoiding the waste of toner accumulated on the sealing ring 23, improving the utilization rate of the toner, and keeping the sealing ring 23 clean.

[0031] like Figure 4 As shown, in this embodiment, an L-shaped connecting rod 26 is fixed to the surface of the powder discharge pipe 2, and a mounting seat 27 is fixed to the bottom of the L-shaped connecting rod 26. The bottom of the mounting seat 27 and the bottom of the powder discharge pipe 2 are in the same plane, and a contact sensor 28 is fixed inside the mounting seat 27. A plurality of vibrators 25 are fixed on the top of the top ring 18. The contact sensor 28 is electrically connected to the vibrator 25. After the powder filling is completed, the shell 5 moves upward, and the sealing plate 32 is attached to the surface of the frame 12. The contact sensor 28 contacts the top ring 18. At this time, the contact sensor 28 triggers the vibrator 25 to start, which can shake off the toner attached to the filter element 22, ensuring the filtration efficiency of the filter element 22, and at the same time making the toner fall to the bottom of the storage chamber 17 for easy collection. The position of the mounting seat 27 ensures that the contact sensor 28 triggers vibration only after the sealing plate 32 closes the through hole 11, so as to avoid leakage when the toner is shaken off.

[0032] like Figure 4 As shown, in this embodiment, a magnetic ring 29 is fixed inside the mounting seat 27. After the powder filling is completed, the housing 5 moves upward, and the magnetic ring 29 is magnetically attracted to the surface of the top ring 18. The magnetic ring 29 magnetically attracts the top ring 18, which can fix the position of the housing 5 and other components after the powder filling is completed, and prevent it from accidentally moving downward and causing the sealing plate 32 to detach from the frame 12, thereby ensuring that the through hole 11 is closed and stable.

[0033] Working principle: First, place the ink cartridge on the pressure sensor on the powder filling machine body 1 and position it through the limit ring. Then move the outer shell 5 downward. The outer shell 5 drives the inner shell 8, the guide cover 13 and the movable tube 21 to move downward synchronously through the connecting rod 16. At this time, the outer shell 5 and the inner shell 8 will cover the opening of the ink cartridge. In this process, under the action of the pulling force of the pull rope 20, the sealing plate 32 flips upward, the sealing plate 32 breaks away from the frame 12 and fits with the frame 2 15 at the through hole 14. Start the suction machine 3. The suction machine 3 works to form a negative pressure at the through hole 11, so that the toner scattered from the ink cartridge mouth during the powder filling process will be guided by the guide cover 13 and smoothly enter the storage chamber 17 from the through hole 11, so as to prevent the toner from floating into the air, thereby protecting the health of the operator. The powder filling work proceeds normally, and the toner enters the ink cartridge through the powder outlet pipe 2 and the movable tube 21; After the powder filling is completed, the housing 5 is moved upward, and the housing 5 drives the relevant components to move upward. The pulling force of the pull rope 20 on the sealing plate 32 gradually disappears, and the sealing plate 32 rotates downward under the action of gravity. The sealing plate 32 is separated from the frame 2 15 at the through hole 2 14 and finally fits on the frame 12 at the through hole 11. Since the frame 12 is made of magnetic material and the side opposite to the sealing plate 32 is flat, the sealing plate 32 can be tightly fitted on the sealing ring of the frame 12 under the action of magnetic adsorption, thereby sealing the through hole 11 and preventing the toner in the storage chamber 17 from floating out from the through hole 11. As the housing 5 moves upward, the top ring 18 gradually approaches the mounting seat 27. When the sealing plate 32 is stably attached to the surface of the frame 12, the top ring 18 contacts the contact sensor 28 in the mounting seat 27. The contact sensor 28 is triggered, and the vibrator 25 is activated. The vibrator 25 vibrates, shaking off the toner attached to the filter element 22 and storing it at the bottom of the storage chamber 17. This not only ensures the filtering performance of the filter element 22, but also improves the toner collection effect. At the same time, the magnetic ring 29 in the mounting seat 27 will be magnetically attracted to the surface of the top ring 18, so that the solid shell 5 and other components will be suspended on the upper side of the ink cartridge. After the ink cartridge that has been filled with powder is transported away, the cyclic filling operation will be carried out; the toner stored in the storage cavity 17 can be subsequently processed, avoiding toner waste.

[0034] It should be noted that the suction pressure of the suction machine 3 is adjustable so that the negative pressure formed at the through hole 11 can ensure the absorption of the scattered toner while controlling the influence on the weighing accuracy of the toner in the ink cartridge within the error range.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
