Description

Technical Field

[0001] The utility model belongs to the technical field of carbon powder recovery equipment, and in particular relates to a high-efficiency carbon powder recovery device. Background Art

[0002] Waste toner cartridges without physical damage can be reused by replacing the chip and refilling toner. At present, there is a mature toner refilling technology in China. Even if some toner cartridge manufacturers set restrictions on the chip, for toner cartridges that have been damaged and cannot be refilled with toner, the metal, plastic and other parts can be recycled by harmless disassembly methods. As for the toner that can no longer be used, it can also be recycled and reused, which can further reduce production costs.

[0003] However, carbon powder will clump if left for a long time. In order to fully recycle it, China Utility Model Patent CN210546301U provides an efficient tungsten carbide powder recovery device, which can rotate the rotating rod through the power provided by the rotating motor. Through the rotation of the rotating rod, in conjunction with the stirring rod, the tungsten carbide powder inside the recovery box is crushed and stirred evenly. At the same time, the power provided by the vibration motor, in conjunction with the chute, slider and spring, plays a role in vibrating the filter screen to screen the tungsten carbide powder for easy recovery.

[0004] Although the above-mentioned recovery device can achieve the purpose of recycling by crushing lumps and screening carbon powder, the filtering through continuous vibration of the screening can easily cause the screen to become clogged. Once clogged, the subsequent carbon powder cannot be screened quickly. Moreover, the crushing can only be performed once by stirring, and the crushing is not thorough enough, which leads to low recovery efficiency, easy clogging, and the need to clean the filter frequently. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency carbon powder recovery device, which can utilize the high-speed rotation of the filter cartridge to screen the carbon powder and utilize the grinding roller to quickly crush the agglomerated carbon powder inside it at the same time. The incomplete crushing can be continuously crushed, thereby reducing the probability of blockage, having high recovery efficiency and low failure rate.

[0006] The technical solution adopted by the utility model is as follows:

[0012] The sealed outer shell is provided with sealing covers at both ends of the filter cartridge, the feed pipe passes through the sealing covers and extends to the outside of the sealed outer shell, and the feed pipe extends to the inside of the filter cartridge and a bulk hopper is fixedly installed at one end.

[0013] The driving mechanism includes driven gears fixedly mounted on the outer surfaces of both ends of the filter cartridge, a driving gear rotatably connected to the bracket, and a servo motor fixedly mounted on the bracket. The driving gears are symmetrically arranged on both sides of the driven gears and meshed with the driven gears. The servo motor is connected to one of the driving gears through a reducer.

[0014] A synchronous connecting rod is arranged between two sets of driving gears on adjacent sides, and the synchronous connecting rod is connected to the driving shaft of the driving gear via a universal shaft.

[0015] The grinding rollers are arranged in a circular array on the sealing seat, and at least two groups are arranged. A central support roller for supporting the grinding rollers is fixedly installed on the sealing seat. An elastic support ring is rotatably connected to the central support roller, and the grinding roller is fixedly sleeved on the elastic support ring.

DETAILED DESCRIPTION

[0031] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0032] like Figure 1-8 As shown, a high-efficiency carbon powder recovery device comprises a bracket 1, a sealed outer shell 2 fixedly mounted on the bracket 1, a filter cartridge 3 embedded in the sealed outer shell 2, and a sealing seat 4 fixedly connected to the bracket 1 and sealingly rotatably connected to one end of the filter cartridge 3;

[0033] A discharge pipe 21 for discharging materials is provided at the center of the bottom of the sealed outer shell 2, and a feed pipe 31 is provided at one end of the filter cartridge 3 to extend into the inside thereof, so as to facilitate feeding materials into the filter cartridge 3;

[0034] Furthermore, in order to ensure air tightness and prevent carbon powder from leaking, the sealed outer shell 2 is provided with sealing covers at both ends of the filter cartridge 3, and the feed pipe 31 extends through the sealing cover to the outside of the sealed outer shell 2. At the same time, the feed pipe 31 extends to the inside of the filter cartridge 3 and a bulk hopper 32 is fixedly installed at one end to facilitate the falling of carbon powder.

[0035] Refer to the attached Figure 2 In order to drive the filter cartridge 3 to rotate at high speed in the sealed outer shell 2 to filter the carbon powder, driven gears 33 are fixedly installed on the outer surfaces of both ends of the filter cartridge 3, and a driving gear 34 is rotatably connected to the bracket 1, and a servo motor 35 is fixedly installed on the bracket 1. The driving gears 34 are symmetrically arranged on both sides of the driven gear 33 and mesh with the driven gear 33. The servo motor 35 is connected to one of the driving gears 34 through a reducer;

[0036] Furthermore, in order to make the two ends of the filter cartridge 3 rotate synchronously, a synchronous connecting rod 36 is provided between the two sets of driving gears 34 on the adjacent side, and the synchronous connecting rod 36 is connected to the driving shaft of the driving gear 34 by a universal shaft 37, which can ensure the stability of power transmission;

[0037] In this embodiment, four groups of driving gears 34 are provided, and only two of them are connected through transmission by synchronous connecting rods 36, and the other two groups rotate with the filter cartridge 3, and their positions are limited at the same time to ensure the stability of their rotation so as not to deviate from the rotating track. Then, the servo motor 35 drives the driving gear 34 to rotate, and the driving gear 34 and the servo motor 35 are engaged with each other to drive the filter cartridge 3 to rotate at high speed inside the sealed outer shell 2, thereby rotating and screening the carbon powder.

[0038] Refer to the attached Figure 3-8 In order to crush the agglomerated carbon powder, a grinding roller 41 and a crushing blade 42 are provided on the sealing seat 4. The grinding roller 41 is attached to the inner wall of the filter cartridge 3, and the crushing blade 42 is provided at the rotation center of the filter cartridge 3.

[0039] Furthermore, the grinding rollers 41 are arranged in a circumferential array on the sealing seat 4, and at least two groups are arranged. In this embodiment, three groups are arranged. A central support roller 411 for supporting the grinding roller 41 is fixedly installed on the sealing seat 4, and an elastic support ring 412 is rotatably connected to the central support roller 411, and the grinding roller 41 is fixedly sleeved on the elastic support ring 412. The elastic support ring 412 can be used to deform the grinding roller 41 to always fit the inner wall of the filter cartridge 3 by its elastic force. Then, the agglomerated carbon powder will continuously contact the grinding roller 41 under the high-speed moving trend of the filter cartridge 3, so as to be continuously crushed. In addition, when encountering a large agglomerate that cannot be crushed, the elastic deformation can also be used for buffering to avoid damage to the equipment.

[0040] Furthermore, in order to improve the crushing efficiency, a connecting seat 421 is fixedly installed at the center of the sealing seat 4, and a crushing blade 42 is fixedly installed at the circumference of the connecting seat 421. The crushing blades 42 are arranged in a circular array on the connecting seat 421, and at least two groups are arranged. In this embodiment, two groups are arranged. By extending the crushing blades 42 in a spiral shape in the filter cartridge 3, and the extension length of the crushing blades 42 is the same as the length of the grinding roller 41, while the grinding roller 41 crushes the agglomerates, other agglomerates can also be fully contacted with the crushing blades 42 during the rotation process, and the agglomerated carbon powder can be fully crushed to ensure that it can be quickly recovered. The spiral structure is conducive to the flow of carbon powder, so that carbon powder at different positions can be fully contacted with the crushing blades 42, thereby improving the crushing efficiency.

[0041] The working principle of the utility model is as follows: when in use, first, the carbon powder to be recycled is added into the filter cartridge 3 through the feed pipe 31, and the servo motor 35 is started at the same time, and the driving gear 34 is driven to rotate by the servo motor 35, and the driving gear 34 is meshed with the driven gear 33 to drive the filter cartridge 3 to rotate at a high speed inside the sealed outer shell 2, so as to perform rotation screening on the carbon powder;

[0042] Secondly, the agglomerated carbon powder will continuously contact the grinding roller 41 under the high-speed movement trend of the filter cartridge 3, thereby being continuously crushed. At the same time, it will also fully contact the crushing blade 42 during the rotation process, thereby fully crushing the agglomerated carbon powder to ensure that it can be quickly recovered;

[0043] Finally, the to-be-recycled carbon powder is continuously added through the feed pipe 31, and the agglomerated carbon powder is continuously crushed by the interaction of the filter cartridge 3, the grinding roller 41, and the crushing blade 42, and then filtered by the filter cartridge 3 into the sealed outer shell 2, and discharged through the discharge pipe 21 for recycling.

[0044] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
