Abstract
Description
Technical Field
[0001] This utility model belongs to the field of information destruction equipment technology, and relates to a toner separation system for a toner cartridge pulverizer. Background Technology
[0002] The toner cartridge is the core imaging component in laser printers and copiers. It converts digital signals into visible images through the photoelectric effect, directly affecting print quality and efficiency.
[0003] Because the printed content inside a toner cartridge is recoverable, a damaged toner cartridge needs to be disposed of through certain means. Currently, the general practice for disposing of toner cartridges is to shred them and then sort the fragments, with metal parts being recycled and sold and plastic parts being discarded. However, a certain amount of toner often remains in the toner cartridge. The above methods cannot effectively recover the toner, and the sorting process often causes it to scatter and drift, polluting the environment. Moreover, if the operator accidentally inhales it, it can cause harm to their health. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a toner separation system for a toner cartridge shredder. The technical problem this invention aims to solve is: how to collect toner from the toner cartridge.
[0005] The objective of this utility model can be achieved through the following technical solution: A toner separation system for a toner cartridge pulverizer, the toner cartridge pulverizer including a cabinet with an internal hopper, characterized in that the toner separation system includes a sieve cylinder with several sieve holes on its outer peripheral wall and penetrating at both ends, and a magnetic conveyor belt, and a stirring mechanism is rotatably connected inside the sieve cylinder along the axial direction, the hopper, the sieve cylinder and the magnetic conveyor belt are arranged sequentially from top to bottom, a separation box is fixed inside the cabinet outside the sieve cylinder, the separation box has an inlet connected to the outlet of the hopper and an outlet located directly above the magnetic conveyor belt, one end of the sieve cylinder is connected to the inlet and the other end is connected to the outlet.
[0006] In the toner separation system of this toner cartridge shredder, the cabinet serves as the main external frame. Besides the internally installed hopper, screen cylinder, magnetic conveyor belt, and separation box, it also houses a shredding box structure located above the hopper. The specific structure of this shredding box can be found in CN202023333212. During operation, the operator feeds the complete toner cartridge into the shredding box through the feeding port on the cabinet. The cutting components inside the shredding box crush the toner cartridge into fragments. These fragments fall into the hopper under gravity. The hopper acts as a transfer point, allowing the fragments to concentrate and enter the separation box through its output port and the separation box's inlet. These fragments also enter the screen cylinder from one end. At this time, the stirring mechanism inside the screen cylinder rotates, continuously agitating the fragments inside the screen cylinder, thus sieving out toner mixed with metal and plastic fragments. The process involves effectively separating residual toner from the drum. The separated toner is then output through the sieve holes on the outside of the sieve cylinder to the separation box and enters the next process. Metal and plastic fragments are output through the other end of the sieve cylinder and through the outlet of the separation box to the magnetic conveyor belt. During the conveying process, the magnetic conveyor belt magnetically attracts the metal fragments. When all the fragments are conveyed to the output end of the magnetic conveyor belt, the plastic parts fall first due to gravity, while the metal fragments fall due to gravity as they move with the magnetic conveyor belt to the non-magnetic area. In this way, the complete drum is effectively screened after being crushed, thus achieving effective classification. This ensures both the rapid processing of metal and plastic parts and the harmless treatment of residual toner, avoiding environmental pollution and ensuring the safety of operators during operation.
[0007] In the toner separation system of the aforementioned toner cartridge shredder, the stirring mechanism includes a rotating shaft driven by a motor. Several stirring rods are fixed circumferentially on the outer wall of the rotating shaft, arranged axially along the screen cylinder. These stirring rods are spaced apart circumferentially along the rotating shaft and close to the inner wall of the screen cylinder. Thus, the motor drives the rotating shaft to rotate within the screen cylinder, and the stirring rods rotate synchronously with the rotating shaft, thereby stirring and agitating the fragments within the screen cylinder, ensuring effective toner sieving. Furthermore, the stirring rods' proximity to the inner wall of the screen cylinder continuously pushes the sieved toner, causing it to slide along the inner wall of the screen cylinder and fall through the corresponding screen holes, preventing toner accumulation within the screen cylinder.
[0008] In the toner separation system of the aforementioned toner cartridge shredder, several connecting rods are radially fixed to the outer wall of the rotating shaft. These connecting rods are divided into several groups along the axial direction of the rotating shaft, and each group of connecting rods is fixedly connected to one of the stirring rods. This ensures higher connection stability between the stirring rods and the rotating shaft.
[0009] In the toner separation system of the aforementioned toner cartridge shredder, the stirring mechanism further includes linkage rings located at both ends of the screen cylinder, with their outer walls attached to the inner walls of the screen cylinder. One end of each stirring rod is fixedly connected to the inner wall of one of the linkage rings, and the other end is fixedly connected to the inner wall of the other linkage ring. Connecting the two ends of each stirring rod via the linkage rings ensures the structural stability of each stirring rod. During the stirring and turning process, it prevents metal and plastic parts from impacting the stirring rods and causing them to vibrate, thereby preventing toner from being dispersed within the screen cylinder and separation chamber due to the vibration of the stirring rods. Furthermore, the linkage rings also limit the movement of the screened toner, preventing it from sliding down the inner wall of the screen cylinder from the end connected to the discharge port of the separation chamber.
[0010] In the toner separation system of the aforementioned toner cartridge shredder, the screen cylinder is inclined downwards from the end connected to the feed inlet to the end connected to the discharge outlet, and the centerline of the rotating shaft coincides with the centerline of the screen cylinder. This allows the screened and filtered metal and plastic fragments to fall from the discharge outlet of the separation box under the action of gravity and with the assistance of the stirring mechanism.
[0011] In the toner separation system of the aforementioned toner cartridge shredder, a conveying pipe is installed inside the cabinet between the hopper and the separation chamber. One end of the conveying pipe is fixedly connected to the hopper and communicates with its output port, while the other end passes through the inlet and extends into the sieve cylinder. This arrangement ensures that all the crushed fragments enter the sieve cylinder within the separation chamber, preventing some fragments from falling into the cabinet through the gap between the hopper and the separation chamber.
[0012] In the toner separation system of the aforementioned toner cartridge shredder, a baffle is vertically fixed inside the separation chamber. One side of the baffle seals one end of the sieve cylinder that connects to the feed inlet. The baffle has a through-shaft hole and a through-pipe opening. The rotating shaft passes through the through-shaft hole, and the conveying pipe passes through the through-pipe opening. The baffle effectively blocks and limits the metal and plastic fragments entering the separation chamber, preventing them from remaining inside.
[0013] In the toner separation system of the aforementioned toner cartridge shredder, the cabinet contains two collection boxes arranged side-by-side. Collection box one is located directly below the output end of the magnetic conveyor belt, and collection box two is located near the output end of the magnetic conveyor belt. After filtration and screening, the separated metal and plastic fragments are transported by the magnetic conveyor belt. Due to the magnetic effect, the metal fragments are attracted to the surface of the magnetic conveyor belt, while the plastic fragments fall in a parabolic trajectory due to inertia and gravity when they reach the edge of the output end of the magnetic conveyor belt and are collected by collection box two. When the metal fragments move to the back of the magnetic conveyor belt, since the magnetic conveyor belt is a non-magnetic area, they fall into collection box one under the influence of gravity for collection.
[0014] Compared with existing technologies, the toner separation system of this toner cartridge shredder has the following advantages: the toner cartridge fragments, which have been shredded and output from the hopper, are received by a screen cylinder fixed in the separation box. The stirring mechanism connected to the screen cylinder is used to sift out the toner from the numerous fragments through the stirring action of the screen cylinder. The toner is then collected through the screen holes on the screen cylinder. At the same time, the remaining fragments are output from the discharge port of the separation box to the magnetic conveyor belt. The magnetic conveyor belt separates and transports plastic fragments and metal fragments and collects them separately through collection boxes one and two. This ensures that the fragments are not mixed with toner, which is convenient for subsequent processing. At the same time, it can prevent toner pollution of the environment and avoid the impact on the operator's health during the processing. Attached Figure Description

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0024] like Figure 1-4 As shown, in the toner separation system of this toner cartridge shredder, the toner cartridge shredder includes a cabinet 1 with an internal cavity. A shredding box structure for crushing complete toner cartridges is fixedly installed in the cavity of the cabinet 1. In addition, a hopper 11 is provided below the shredding box in the tube and is connected to the shredding box by screws, so that the inlet of the hopper 11 is connected to the outlet of the shredding box. The toner separation system includes a cylindrical screen 12 with both ends through and a magnetic conveyor belt 13. A number of spaced screen holes (not shown in the figure) are opened on the circumferential side wall of the screen 12. It is worth mentioning that the shredding box and magnetic conveyor belt 13 disclosed in this embodiment are prior art, and the specific structure of the two will not be described in detail in this application.
[0025] The material hopper 11, screen cylinder 12, and magnetic conveyor belt 13 are arranged sequentially from top to bottom, combined with... Figure 6 Inside the cabinet 1, a separation box 14 with an internal cavity is fixed to the outer sleeve of the screen cylinder 12. The separation box 14 is provided with an inlet 141 and an outlet 142. Specifically, the inlet 141 is located at one end of the separation box 14 and is located near its top, and the outlet 142 is located at the bottom of the separation box 14 and is located near its other end. A conveying pipe 15 is provided between the hopper 11 and the separation box 14. One end of the conveying pipe 15 is fixed to the outlet of the hopper 11 by screws, and the other end passes through the inlet 141 of the separation box 14 and extends into the screen cylinder 12 from one end. The other end of the screen cylinder 12 is connected to the outlet 142 of the separation box 14.
[0026] Combination Figure 5A stirring mechanism 2 is rotatably connected to the screen cylinder 12 along the axial direction. Specifically, the stirring mechanism 2 includes a rotating shaft 21 that passes through the separation box 14. The separation box 14 is abutted against the frame of the cabinet 1 by the external flange and locked by bolts. Bearing seats are fixed at both ends of the separation box 14 inside the cabinet 1. The two ends of the rotating shaft 21 are fixed to the bearings in the two bearing seats respectively. A driven ratchet is fixed at one end of the rotating shaft 21. A motor is fixed at one end of the separation box 14 inside the cabinet 1, and a driving ratchet is fixed on the output shaft of the motor. The driving ratchet and the driven ratchet are connected by a chain for transmission, thereby realizing the rotation of the rotating shaft 21 inside the screen cylinder 12.
[0027] In addition, the stirring mechanism 2 also includes several stirring rods 211 arranged along the axial direction of the screen cylinder 12 and close to the inner wall of the screen cylinder 12. The stirring rods 211 are arranged at intervals along the axial direction of the rotating shaft 21. Several connecting rods 212 are fixed on the outer wall of the rotating shaft 21 and arranged radially thereon. The connecting rods 212 are divided into several groups along the axial direction of the rotating shaft 21. The several groups of connecting rods 212 and the several stirring rods 211 are fixed together in a one-to-one correspondence. A linkage ring 22 is provided at both ends inside the screen cylinder 12. The outer side wall of each linkage ring 22 is in contact with the inner side wall of the screen cylinder 12. The inner side wall of one linkage ring 22 is welded and fixed to one end of several stirring rods 211, and the inner side wall of the other linkage ring 22 is welded and fixed to the other end of several stirring rods 211. Secondly, the screen cylinder 12 is inclined downward from the end connected to the feed inlet 141 to the end connected to the discharge outlet 142, and the center line of the rotating shaft 21 coincides with the center line of the screen cylinder 12, that is, the inclination of the rotating shaft 21 and the screen cylinder 12 is the same. As an alternative, the stirring mechanism 2 may also include a rotating shaft 21 passing through the separation box 14 and a rectangular rotating plate fixed to the outer wall of the rotating shaft 21 along the axial direction of the screen cylinder 12, and several rotating plates are spaced apart along the axial direction of the rotating shaft 21.
[0028] Combination Figure 7 Inside the separation box 14, a baffle 143 is fixed vertically. One side of the baffle 143 is pressed against one end of the feed inlet 141 of the screen cylinder 12, thereby sealing that end of the screen cylinder 12. A through-shaft hole 1431 and a through-pipe port 1432 located above the through-shaft hole 1431 are provided on the baffle 143. The rotating shaft 21 passes through the through-shaft hole 1431, and the other end of the conveying pipe 15 passes through the through-pipe port 1432.
[0029] The discharge port 142 of the separation box 14 is specifically located near the input end of the magnetic conveyor belt 13. Inside the cabinet 1, a collection box 16 and a collection box 2 17 are arranged side by side below the magnetic conveyor belt 13. The collection box 16 is located near the output end of the magnetic conveyor belt 13 and faces the lower side of the magnetic conveyor belt 13. The collection box 2 17 is located near the output end of the magnetic conveyor belt 13 and is located in front of the collection box 16.
[0030] Working principle: The operator feeds the toner cartridge into the pulverizing chamber through the feeding port of cabinet 1. The cartridge is then pulverized into fragments. These fragments are received by the hopper 11 and fed into the separation chamber 14 through the feed inlet 141 via the conveying pipe 15. Under gravity, the fragments fall into the sieve cylinder 12. At this time, the rotating shaft 21 is driven to rotate several stirring rods 211 to stir and agitate the fragments in the sieve cylinder 12, causing the toner encased in the fragments to detach and fall through the sieve holes on the sieve cylinder 12 into the separation chamber 14. 14. These toner particles are collected separately. Then, the remaining fragments fall onto the magnetic conveyor belt 13 through the discharge port 142 of the collection box under the action of gravity. Due to the characteristics of the magnetic conveyor belt 13, the metal fragments are attracted and transported to the edge of its output end. The plastic fragments fall into the second collection box 17 for separate collection due to gravity. The metal fragments fall into the first collection box 16 for collection when they move to the lower belt surface as the magnetic attraction effect disappears. In this way, the toner cartridge is completely crushed and reasonably screened and collected.
