Description

Technical Field

[0001] This utility model relates to the technical field of printing consumables recycling equipment, and in particular to a toner recycling device for toner cartridges. Background Technology

[0002] With the widespread use of office equipment, printers have become common tools in daily work, and toner cartridges, as their core consumables, are replaced frequently. Discarded toner cartridges usually still contain a large amount of unused toner. If discarded directly, this not only wastes resources but also pollutes the environment. In particular, the problem of toner particle dust dispersion has become one of the key environmental hazards in the recycling and disposal of waste consumables.

[0003] Existing toner recycling methods mainly include manual dumping and vibrating sieving. Although manual dismantling is simple in structure and low in cost, it generates dust during operation and has low recycling efficiency. Vibrating sieving uses mechanical vibration to peel off toner, which improves efficiency, but it is prone to toner clumping, affecting the recycling effect. Utility Model Content

[0004] Based on this, it is necessary to address the existing toner recycling methods, which mainly include manual dumping and vibratory sieving. While manual dismantling is simple in structure and low in cost, it generates dust during operation and has low recycling efficiency. Vibratory sieving, which uses mechanical vibration to peel off toner, improves efficiency but is prone to toner clumping, affecting the recycling effect. Therefore, a toner recycling device is provided, comprising: a recycling box with a lid fixedly installed on its top; and a cleaning and recycling mechanism for recycling toner from the toner drum. The cleaning and recycling mechanism includes multiple electrically operated cleaning brushes disposed inside the recycling box, a recycling component is disposed inside the recycling box, and a feeding component is disposed outside the multiple electrically operated cleaning brushes.

[0005] The recycling assembly includes a fixed frame fixedly installed inside the recycling bin, an air pump fixedly installed on the outside of the recycling bin, the suction end of the air pump extending into the inside of the fixed frame, a movable frame provided inside the fixed frame, and a first filter screen fixedly installed on the surface of the movable frame, the first filter screen being located on one side of the suction end of the air pump.

[0006] The first filter screen is configured as a ring shape, and a first motor is fixedly installed at the bottom of the recycling bin. The output end of the first motor extends to the bottom of the movable frame, and the bottom of the movable frame is slidably connected to the output end of the first motor.

[0007] The bottom of the movable frame is fixedly equipped with a plurality of first contact blocks, and the inner bottom wall of the fixed frame is fixedly equipped with a plurality of second contact blocks, with the plurality of first contact blocks and second contact blocks being distributed alternately.

[0008] The sides of the first contact block and the second contact block that are close to each other are both set to a semi-circular shape, and the first contact block and the second contact block are both distributed in a circumferential manner at equal intervals.

[0009] The feeding assembly includes an air guide frame fixedly installed on the surface of the recycling bin, the air guide frame being located on top of two electric cleaning brushes.

[0010] The air guide frame is set at an angle, and a second filter screen is fixedly attached inside the air guide frame.

[0011] The recycling bin is fixedly equipped with a support frame inside. Both electric cleaning brushes are fixedly installed on the surface of the support frame. A placement rod is provided on the surface of the support frame. A guide plate is fixedly installed on the surface of the support frame. The guide plate is shaped like a frustum and is located outside the placement rod. A second motor is fixedly installed at the bottom of the support frame. The output end of the second motor is fixedly connected to the bottom end of the placement rod.

[0012] Beneficial effects

[0013] The above-mentioned toner recycling device.

[0014] 1. By setting multiple electric cleaning brushes, the surface of the toner cartridge can be cleaned simultaneously, improving toner stripping efficiency; the recycling component provides continuous suction during operation, working with the cleaning brushes to promptly suck up the stripped toner and prevent dust from spreading; the feeding component guides the fallen toner to the recycling path, improving collection efficiency.

[0015] 2. External gas enters the recycling bin through the air guide frame. The air guide frame is aligned with the position of the drum unit.

[0028] The following is combined with Figures 1-4 This invention describes a toner recycling device for toner cartridges.

[0029] In one embodiment, a toner recycling device includes: a recycling bin 100, with a bin cover 200 fixedly installed on the top of the recycling bin 100; and a cleaning and recycling mechanism 300 for recycling toner inside the toner drum. The cleaning and recycling mechanism 300 includes a plurality of electric cleaning brushes 310 disposed inside the recycling bin 100, a recycling assembly 320 disposed inside the recycling bin 100, and a feeding assembly 330 disposed outside the plurality of electric cleaning brushes 310.

[0030] In this embodiment, by setting multiple electric cleaning brushes 310, the toner cartridge can be cleaned simultaneously on multiple surfaces after being placed inside the recycling bin 100, which improves the efficiency of toner stripping. The recycling component 320 provides continuous suction during device operation and works in conjunction with the electric cleaning brushes 310 to promptly suck the stripped toner into the recycling path, preventing dust from spreading inside the recycling bin 100. The feeding component 330 can guide the falling toner to collect in the recycling component 320, improving dust concentration and recycling efficiency.

[0031] It should be noted that existing toner cartridge recycling devices typically include a recycling bin 100, a manual disassembly station, a dust collection unit, and a filtration system. They mainly perform rough cleaning of waste toner cartridges through manual disassembly or a single-sided vibration device. Multiple electric cleaning brushes 310 and a feeding assembly 330 are arranged in different positions inside the recycling bin 100. Structurally, they are independent of the main recycling path and do not change the final flow direction of the toner, nor do they interfere with the normal adsorption action of the recycling assembly 320. The electric cleaning brushes 310 only operate within the toner cartridge clamping area and maintain flexible contact with the toner cartridge. The feeding assembly 330, as a dust guiding device, only guides the direction of falling toner and assists in its concentration. Its operation is undisturbed and does not affect the stability of the negative pressure of the recycling channel. Therefore, none of them interfere with or conflict with the overall operation of the toner cartridge recycling device.

[0032] like Figure 2 and Figure 3 As shown, the recycling assembly 320 includes a fixed frame 321 fixedly installed inside the recycling bin 100. An air pump 311 is fixedly installed on the outside of the recycling bin 100. The suction end of the air pump 311 extends into the interior of the fixed frame 321. A movable frame 322 is provided inside the fixed frame 321. A first filter screen 323 is fixedly installed on the surface of the movable frame 322. The first filter screen 323 is located on one side of the suction end of the air pump 311.

[0033] In this embodiment, after the suction pump 311 is started, it creates a negative pressure environment inside the fixed frame 321 through its suction end, and sucks the toner particles peeled off by the electric cleaning brush 310 along with the air into the fixed frame 321. The movable frame 322 remains stable under the action of airflow. The first filter 323 fixedly installed on the surface of the movable frame 322 can perform preliminary filtration of large particulate impurities and toner in the suction airflow, preventing them from directly entering the suction pump 311 and causing blockage or wear. The movable frame 322 is a detachable structure, which is convenient for regular cleaning.

[0034] The first filter screen 323 is set in a circular shape. The bottom of the recycling box 100 is fixedly installed with a first motor 324. The output end of the first motor 324 extends to the bottom of the movable frame 322. The bottom of the movable frame 322 is slidably connected to the output end of the first motor 324.

[0035] In this embodiment, the first filter 323 is set in a circular shape, which can form a closed filter ring around the suction end of the suction pump 311, providing a larger filtration path and enhancing the separation efficiency of toner and airflow. When the first motor 324 is running, it can drive the movable frame 322 to rotate inside the fixed frame 321, so that the first filter 323 moves continuously in the suction path, effectively preventing dust from accumulating and clogging on the filter surface.

[0036] Multiple first contact blocks 325 are fixedly installed at the bottom of the movable frame 322, and multiple second contact blocks 326 are fixedly installed on the inner bottom wall of the fixed frame 321. The multiple first contact blocks 325 and second contact blocks 326 are distributed alternately.

[0037] In this embodiment, when the first motor 324 drives the movable frame 322 to rotate, the first contact block 325 and the second contact block 326 periodically contact and separate during this process, forming a slight mechanical vibration or friction, which disturbs and shakes the surface of the first filter screen 323, helping the toner particles attached to the filter screen to fall off to the bottom of the recycling bin 100.

[0038] The first contact block 325 and the second contact block 326 are both set to a semi-circular shape on the side that is close to each other, and the first contact block 325 and the second contact block 326 are both distributed in a circumferential manner at equal intervals.

[0039] In this embodiment, the sides of the first contact block 325 and the second contact block 326 that are close to each other are both set to a semi-circular shape, which can achieve flexible contact and buffer impact during the up and down sliding process. The multiple first contact blocks 325 and second contact blocks 326 are all distributed in a ring shape at equal intervals, which can ensure that the entire movable frame 322 is subjected to uniform force during the sliding process.

[0040] like Figure 2 and Figure 4 As shown, the feeding assembly 330 includes an air guide frame 331 fixedly mounted on the surface of the recycling bin 100, the air guide frame 331 being located on top of two electric cleaning brushes 310.

[0041] In this embodiment, when the suction pump 311 is working, it creates negative pressure through its suction end, and external gas enters the inside of the recycling box 100 through the air guide frame 331. The air guide frame 331 is located on top of the two electric cleaning brushes 310 and is aligned with the position of the toner drum. It can guide the airflow directly over the top of the toner drum and flow downward while the toner is peeled off by the brush bristles, thereby forming a stable airflow path from top to bottom, which quickly brings the floating toner into the area where the recycling component 320 is located for concentrated adsorption, reducing the diffusion or drift of toner inside the box.

[0042] The air guide frame 331 is set at an angle, and the second filter 332 is fixedly attached inside the air guide frame 331.

[0043] In this embodiment, external airflow can be introduced into the recycling bin 100 at an angle, effectively guiding the airflow along the surface of the drum. A second filter 332 is fixedly attached inside the air guide frame 331. The second filter 332 can perform preliminary filtration of external dust or particles carried in the airflow before it enters the recycling bin 100, preventing non-target impurities from entering the system.

[0044] A support frame 333 is fixedly installed inside the recycling bin 100. Two electric cleaning brushes 310 are fixedly installed on the surface of the support frame 333. A placement rod 334 is provided on the surface of the support frame 333. A guide plate 336 is fixedly installed on the surface of the support frame 333. The guide plate 336 is shaped like a frustum and is located outside the placement rod 334. A second motor 335 is fixedly installed at the bottom of the support frame 333. The output end of the second motor 335 is fixedly connected to the bottom end of the placement rod 334.

[0045] In this embodiment, a sealing shell is fixedly installed on the outside of the second motor 335. Driven by the second motor 335, the placement rod 334 drives the drum to rotate between multiple electric cleaning brushes 310, so that the cleaning brushes can perform multi-angle and uniform brushing on the outer wall of the drum, improving the toner stripping efficiency. The placement rod 334 is flat and elliptical, which can stably drive the drum to rotate.

[0046] Working principle: Open the cover 200 and place the waste toner cartridge on the placement rod 334 on the support frame 333. The guide plate 336 acts as a limit to ensure accurate positioning. Start the second motor 335 to drive the placement rod 334 to rotate, causing the toner cartridge to rotate between multiple electric cleaning brushes 310. The cleaning brushes work simultaneously at multiple points on its surface, effectively removing residual toner. After the toner is removed, it falls naturally to the feeding component 330. The obliquely set air guide frame 331 guides the airflow from top to bottom through the toner cartridge and carries the toner into the recycling path. The suction pump 311 continuously provides negative pressure suction, which is then passed through the recycling component. 320 draws toner and dust into the fixed frame 321. The airflow entering the fixed frame 321 is first filtered by the first filter 323 on the surface of the movable frame 322. Large particles are blocked and fall to the bottom of the box. To prevent the first filter 323 from clogging, the first motor 324 drives the movable frame 322 to rotate. At the same time, the first contact block 325 and the second contact block 326 periodically contact each other to generate vibration, causing the dust attached to the filter to fall off. All the drawn-in air is finally discharged by the suction pump 311. The second filter 332 set at the air inlet can block impurities carried in the outside air from entering the system, ensuring a clean and stable operating environment for the whole machine.

[0047] It should be noted that the air pump, electric cleaning brush, first motor and second motor mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the air pump, electric cleaning brush, first motor and second motor can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
