Description
Technical Field
[0001] This utility model relates to a toner recycling and sorting device, specifically an automated sorting device for toner recycling. Background Technology
[0002] Recycling waste toner can reduce harmful emissions and mitigate carbon emissions from an environmental perspective. In terms of resource recycling, it promotes sustainable development and achieves a closed loop of "production-use-regeneration," reducing dependence on virgin resources. The core processes of toner recycling include collection and preliminary treatment, sorting and purification, and advanced treatment and reuse. Sorting and purification are the most crucial steps in toner recycling, directly determining the recycling rate.
[0003] Common toner sorting devices include sorting machines, which consist of sorting pipes, vibrating screen structures, and conveying structures. After initial processing, waste toner is continuously conveyed to the sorting pipes. The vibrating screen structure includes a drive structure and a vibrating screen plate. The drive structure causes the vibrating screen plate to vibrate rapidly, thereby sieving the toner. Toner particles smaller than the sorting pores on the vibrating screen plate pass through, while larger particles collect on the vibrating screen plate. This process separates clumped toner and impurities, toner with moderate particle size, and toner with very small particle size, and then conveys them to different recycling devices.
[0004] Because common vibrating screen structures do not have self-cleaning capabilities, as sorting progresses, the amount of toner accumulating on the vibrating screen plate will increase, which can easily cause the vibrating screen plate to become clogged and reduce sorting efficiency. When cleaning the device later, it is necessary to stop the machine, which greatly reduces the sorting efficiency. Summary of the Invention

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1-7 As an embodiment of the present utility model, the automated sorting device for toner recycling includes a chassis 1; The chassis 1 is equipped with a feeding pipe 101, a sorting pipe 2, and a discharge pipe 3; wherein the feeding pipe 101 and the sorting pipe 2 are interconnected. The sorting pipe 2 is provided with multiple sets of screening structures; the screening structure includes multiple sets of second screening plates 8 rotatably installed in the sorting pipe 2; a first screening plate 7 is slidably installed on the second screening plate 8; multiple sets of screening holes are opened on the first screening plate 7 and the second screening plate 8; and the diameter of the screening holes gradually decreases along the vertical direction. Multiple sets of the screening structures divide the sorting pipe 2 into a first chamber 201, a second chamber 202, and a third chamber 203 along the height direction of the sorting pipe 2; Multiple sets of baffles 301 are installed inside the discharge pipe 3; the multiple sets of baffles 301 divide the discharge pipe 3 into multiple discharge chambers, and the multiple sets of discharge chambers are respectively connected to the first chamber 201, the second chamber 202, and the third chamber 203; The first screening plate 7 can drive the second screening plate 8 to rotate. During the rotation, the first screening plate 7 and the second screening plate 8 slide together to accelerate the toner passing through the screening holes and push the toner to move towards the discharge pipe 3.
[0023] In this embodiment, the feed pipe 101 is sealed to the outlet of the toner collection device, and the toner collected by the collection device will enter the sorting pipe 2 through the feed pipe 101.
[0024] Toner first enters the first chamber 201 and gathers on a set of first sieve plates 7 and second sieve plates 8. At this time, toner particles smaller than the diameter of the sieve pores in the first chamber 201 (fine toner particles and medium toner particles) will pass through the sieve pores and enter the second chamber 202, while larger toner particles (clumps or impurities) will remain in the first chamber 201. The toner entering the second chamber 202 will collect on another set of first sieve plates 7 and second sieve plates 8. Toner with a particle size smaller than the sieve pores in the second chamber 202 (smaller particle size toner) will pass through the sieve pores and enter the third chamber 203. Toner with a moderate particle size will remain in the second chamber 202.
[0025] By using multiple sets of screening structures to screen the toner entering the sorting pipe 2, toner of different particle sizes can be effectively separated, preventing mixed toner from entering the regeneration device and reducing the quality of regenerated toner, and improving the utilization rate of waste toner.
[0026] The screening structure drives the first screening plate 7 and the second screening plate 8 to deflect at a small amplitude and high frequency. During the deflection process, the first screening plate 7 and the second screening plate 8 slide and cooperate with each other. This improves the efficiency of toner passing through the screening pores and avoids excessive toner accumulation that could cause clogging of the screening pores. The first screening plate 7 and the second screening plate 8 deflect in the same direction, which can slowly push the sorted toner into the discharge chamber. During the movement of the toner, further sorting can be completed, thereby improving the screening efficiency.
[0027] The screening structure drives the first screening plate 7 and the second screening plate 8 to deflect at a small amplitude and high frequency to improve screening efficiency. The thrust generated by the deflection pushes the toner slowly towards the discharge chamber for timely discharge. This avoids clogging of the screening pores after long-term operation, thereby improving the operating efficiency of the device and reducing subsequent cleaning work.
[0028] As a further embodiment of this utility model, multiple sets of belt rollers 14 are rotatably installed in the multiple unloading chambers; the belt rollers 14 are connected to each other by a conveyor belt 15; and the multiple belt rollers 14 are connected to each other by a belt.
[0029] In this embodiment, when the belt roller 14 rotates, it drives the conveyor belt 15 to rotate, thereby conveying the toner to different recycling devices.
[0030] The sorted toner (clumped toner or impurities) in the first chamber 201 will be moved onto a set of conveyor belts 15 by the sieving structure and transported to a suitable recycling device.
[0031] The sorted toner (toner with appropriate particle size) in the second chamber 202 will move onto a set of conveyor belts 15 under the push of the screening structure and be transported to the matching recycling device.
[0032] The sorted toner (finer particles) in the third chamber 203 will move onto the standing conveyor belt 15 under the push of the screening structure and be transported to the matching recycling device.
[0033] By using different recycling devices to process toner particles of different sizes in different ways, the utilization rate of toner can be effectively improved.
[0034] As a further embodiment of this utility model, a filter structure is provided between the first chamber 201 and the unloading chamber; the filter structure includes a communication station 16 installed on the sorting pipe 2; a motor 4 is installed on the sorting pipe 2; a magnetic roller 5 is installed on the output end of the motor 4; an impurity box 12 is installed on one side of the communication station 16; a discharge plate 1601 is installed on the communication station 16; the discharge plate 1601 extends obliquely into the impurity box 12; a fixing plate 13 is installed on the impurity box 12; a scraper 1301 that is in close contact with the magnetic roller 5 is installed on the fixing plate 13; the fixing plate 13 is in close contact with a set of conveyor belts 15; the magnetic roller 5 is connected to a belt roller 14 via a belt.
[0035] In this embodiment, after the toner is sorted by the screening structure in the first chamber 201, it will push the agglomerated toner and impurities toward the discharge chamber.
[0036] The radio 16 can generate a high-voltage electric field, which will cause the toner to become corona-charged after passing through it, while the plastic impurities will not become charged; and the magnetic roller 5 is grounded.
[0037] Motor 4 drives the magnetic roller 5 to rotate, and drives the belt roller 14 to rotate via the belt, thereby driving multiple sets of conveyor belts 15 to rotate synchronously to complete the toner unloading process.
[0038] Toner collects on the radio 16, and the rotating magnetic roller 5 comes into contact with the toner, thereby adsorbing the toner and causing the toner to rotate synchronously. When the rotating toner moves to the scraper 1301, it will be scraped off by the scraper 1301. Plastic impurities will move towards the impurity box 12 under the push of subsequent toner, and slide down the discharge plate 1601 into the impurity box 12. This completes the separation of toner and plastic impurities, and prevents impurities from entering the recycling device and causing damage to the recycling device.
[0039] The toner scraped off by the scraper 1301 will gradually fall onto the conveyor belt 15 and be transported by the conveyor belt 15 to the recycling device.
[0040] The filtration structure effectively improves the purity of the toner, thereby increasing its utilization rate. It also prevents impurities from entering the subsequent recycling equipment, thus protecting the equipment.
[0041] As a further embodiment of this utility model, the screening structure includes a linkage shaft 6 rotatably mounted on the sorting pipe 2; the linkage shaft 6 is connected to the magnetic roller 5 via a belt; a first bevel gear 601 is mounted on one end of the linkage shaft 6; a vibrating shaft 9 is rotatably mounted on the sorting pipe 2; a second bevel gear 901 meshing with the first bevel gear 601 is mounted on one end of the vibrating shaft 9; a connecting rod 10 is mounted on the other end of the vibrating shaft 9; a protruding column 1001 is mounted on the connecting rod 10; a sliding rod 11 rotatably connected to the first screening plate 7 is slidably fitted inside the sorting pipe 2; a sliding groove 1101 is provided on the sliding rod 11 to slidably fit with the protruding column 1001.
[0042] In this embodiment, when the magnet roller 5 rotates, it drives the linkage shaft 6 to rotate via the belt, thereby driving the first bevel gear 601 to rotate.
[0043] The rotating first bevel gear 601 will drive the second bevel gear 901 to rotate through meshing, thereby driving the vibration shaft 9 to rotate.
[0044] The rotating vibrating shaft 9 will drive the connecting rod 10 to rotate, thereby driving the protruding column 1001 to rotate synchronously. During the rotation of the protruding column 1001, it will slide back and forth in the slide groove 1101 and squeeze the groove wall of the slide groove 1101, thereby driving the slide rod 11 to move up and down back and forth.
[0045] During the reciprocating lifting and lowering process of the slide bar 11, it will drive the first screening plate 7 to move, and under the restriction of the second screening plate 8, it will reciprocate and deflect. During this process, the first screening plate 7 and the second screening plate 8 slide and cooperate with each other.
[0046] The high-frequency, small-amplitude reciprocating deflection of the first screening plate 7 and the second screening plate 8 can quickly shake the toner, thereby improving the screening efficiency of the screening pores. By pushing the screened toner towards the discharge chamber, the toner is prevented from clogging the screening pores, thereby improving the sorting efficiency of the device and reducing the frequency of subsequent cleaning and maintenance of the device, thus improving work efficiency.
[0047] As a further embodiment of this invention, the conveyor belt 15 is made of rubber and is grounded through a conductor.
[0048] In this embodiment, static electricity between the conveyor belt 15 and the toner is eliminated by a conductor, thereby preventing toner from adsorbing onto the conveyor belt 15 and avoiding contamination and damage to the device.
[0049] As a further improvement of this utility model, an insulating gasket is provided between the impurity box 12 and the communication radio 16.
[0050] In this embodiment, an insulating gasket isolates the impurity box 12 from the radio 16, thereby preventing electric shock hazards and improving the safety of the device.
[0051] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
