The travel guide frame is fixedly connected to one side of the crushing and recycling structure. The coordinated design of the crushing and recycling structure and the sorting drive structure facilitates convenient sorting of the inner core and outer shell of lithium batteries, and allows for the crushing and recycling of the separated battery shells while directly recycling the inner core. However, in actual operation, operators need to be in close contact with the crushing equipment to pour the waste lithium batteries into the device, which reduces operational safety. Furthermore, the dust and metal fragments generated during operation may not only threaten the operator's safety but also have adverse environmental impacts.

[0004] Therefore, a closed-loop waste lithium battery crushing device with automatic feeding function is needed. Utility Model Content

The gear set includes a rotating explosion-proof door on the front of the crushing frame, a sliding screening frame inside the crushing frame, two limiting plates fixedly connected to the rear of the crushing frame, a support frame, a servo motor, conveyor rollers, a conveyor belt, connecting plates, and a discharge frame. The bottom plate and the feed frame are fixedly connected to two support frames. A servo motor is installed on the rear of the support frame. Multiple conveyor rollers are rotating inside the support frame. The output shaft of the servo motor is connected to the conveyor rollers on the lower outer side of the support frame. The multiple conveyor rollers are fitted together with a conveyor belt. Multiple connecting plates are evenly distributed on the conveyor belt. The discharge frame is fixedly connected to the support frame.

[0007] As a preferred technical solution of this utility model, it also includes a dual-axis motor, a lead screw, and baffles. A dual-axis motor is installed on the front side of the feeding frame. The two output shafts of the dual-axis motor are connected to the lead screw through a coupling. Two baffles are threaded on the lead screw and slide on the feeding frame.

[0008] As a preferred technical solution of this utility model, it also includes a connecting plate, a rotating rod and a connecting frame. The connecting plate is provided on the left-side tooth crushing roller, the rotating rod is fixedly connected to the connecting plate, and the connecting frame is movably provided on the rotating rod.

[0012] As a preferred technical solution of this utility model, it also includes a transparent plate, which is embedded in the explosion-proof door.

[0013] Compared with the prior art, this utility model provides a closed waste lithium battery crushing device, which has the following beneficial effects: 1. By setting up an automatic feeding mechanism, the operator is prevented from having close contact with the crushing equipment, thus improving the safety of the operation; by designing a sealed structure, dust and metal fragments are effectively prevented from splashing during the operation, which not only protects the safety of the operator, but also reduces the impact on the environment.

[0014] 2. By rotating the lead screw, the baffle moves inward to close the opening of the feed frame, thereby reducing the contact between the chemical substances inside the battery and the air during the crushing process and preventing possible chemical reactions or safety hazards.

[0015] 3. The rotation of the rotating rod will push the connecting frame to move up and down, thereby causing the screening frame to vibrate up and down, thus preventing waste lithium battery fragments from clogging the screening frame and ensuring that the screening process proceeds smoothly.

Detailed Implementation

[0024] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0025] Example 1: A closed-type waste lithium battery crushing device, please refer to... Figures 1-7 The system includes a base plate 1, a crushing frame 2, a feed frame 3, a cover plate 4, a support shell 5, a stepper motor 6, a rotating shaft 7, a toothed crushing roller 8, a spur gear set 9, an explosion-proof door 10, a screening frame 11, and a limiting plate 12. The crushing frame 2 is bolted to the base plate 1. The feed frame 3 is fixedly connected to the top of the crushing frame 2, and the feed frame 3 is covered by a cover plate 4. The support shell 5 is fixedly connected to the rear of the crushing frame 2. A stepper motor 6 is bolted inside the support shell 5. Two rotating shafts 7 are rotatably mounted inside the crushing frame 2, with toothed crushing rollers 8 mounted on them. The output shaft of the stepper motor 6 is connected to the right-side rotating shaft 7. Both rotating shafts 7 are equipped with spur gear sets 9. The explosion-proof door 10 is rotatably mounted on the front of the crushing frame 2. The screening frame 11 is slidably mounted inside the crushing frame 2. Two limiting plates 12 are fixedly connected to the rear of the crushing frame 2. The base plate 1 and the feed frame 3 are jointly fixedly connected to two limiting plates 12. A support frame 13 has a servo motor 14 bolted to its rear side. Four conveyor rollers 15 are rotatably mounted inside the support frame 13. The output shaft of the servo motor 14 is connected to the conveyor rollers 15 on the lower outer side of the support frame 13. The four conveyor rollers 15 are fitted together with a conveyor belt 16. Multiple connecting plates 17 are evenly distributed on the conveyor belt 16. A feeding frame 26 is fixedly connected to the support frame 13. A hopper 25 is bolted to the inside of the crushing frame 2. A folding plate 24 is installed between the hopper 25 and the screening frame 11. The hopper 25 guides the waste lithium battery fragments, making it easy for the fragments to fall into the container smoothly. A noise reduction shell 28 is installed on the front side of the crushing frame 2. A spur gear set 9 is located inside the noise reduction shell 28 to reduce the noise when the spur gear set 9 is working. A transparent plate 29 is embedded in the explosion-proof door 10 to facilitate observation of the amount of waste lithium battery fragments inside the container.

[0026] When it is necessary to crush waste lithium batteries, firstly, the waste lithium batteries are poured into the feeding frame 26. Next, the servo motor 14 is turned on, and the output shaft of the servo motor 14 rotates, driving the conveyor roller 15 on the lower outer side of the support frame 13 to rotate. Then, the conveyor belt 16 causes multiple conveyor rollers 15 to rotate synchronously, conveying the waste lithium batteries upward into the feeding frame 3. This avoids close contact between operators and the crushing equipment, improving operational safety. Next, the stepper motor 6 is started, and the output shaft of the stepper motor 6 rotates, driving the right-side rotating shaft 7 to rotate. Through the transmission action of the spur gear set 9, the left-side rotating shaft 7 also rotates accordingly. The two toothed crushing rollers 8 move relative to each other, effectively crushing the waste lithium batteries. The sealed structure design effectively prevents dust and metal fragments from splashing during operation, protecting the operator's safety and reducing environmental impact. After crushing, the waste lithium battery fragments fall onto the screening frame 11, which screens out large pieces of material that are not completely crushed, ensuring that only fragments that meet the size requirements pass through the screening frame 11 and fall into the pre-prepared collection container; while larger fragments that fail to pass the screening are left on the screening frame 11 for further processing or re-crushing.

[0027] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 3 and Figure 4 A dual-axis motor 18 is bolted to the front of the feed frame 3. The two output shafts of the dual-axis motor 18 are connected to lead screws 19 via couplings. Two baffles 20 are threaded onto the lead screws 19 and slide on the feed frame 3. A protective shell 27 is bolted to the front of the feed frame 3. The dual-axis motor 18 and the lead screws 19 are located inside the protective shell 27 to prevent foreign objects from getting tangled on the lead screws 19.

[0028] When a certain amount of waste lithium batteries accumulate inside the feed frame 3, the dual-axis motor 18 is started. The two output shafts of the dual-axis motor 18 rotate, driving the lead screws 19 on both sides to rotate, causing the baffle 20 to move inward and close the opening of the feed frame 3. This reduces the contact between the chemical substances inside the battery and the air during the crushing process, preventing possible chemical reactions or safety hazards.

[0029] Please see Figure 5 and Figure 6 A connecting plate 21 is provided on the left-side tooth crushing roller 8. A rotating rod 22 is fixedly connected to the connecting plate 21. A connecting frame 23 is movably provided on the rotating rod 22. One end of the connecting frame 23 is connected to the screening frame 11.

[0030] During crushing, the right-side tooth crushing roller 8 rotates, which drives the rotating rod 22 to rotate through the connecting plate 21. The rotation of the rotating rod 22 pushes the connecting frame 23 to move up and down, thereby causing the screening frame 11 to vibrate up and down, thus preventing waste lithium battery fragments from clogging the screening frame 11 and ensuring that the screening process proceeds smoothly.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
