Technical Field

[0001] The utility model relates to the technical field of battery raw material recycling, and more specifically, to a feeding mechanism for recycling sheet-shaped lithium battery raw materials. Background Art

They can be said to be the largest application group. With the continuous development of new energy vehicles, the demand for lithium batteries is also increasing continuously.

[0003] Currently, in the waste lithium battery recycling industry, it is necessary to crush and screen lithium batteries. Especially during the disassembly and recycling process of lithium batteries, after the waste lithium batteries are disassembled, the internal lithium battery sheets are broken into sheet materials with dimensions of about 40mm×50mm or 50mm×50mm, etc., and the thickness is about 0.3mm sheet-like objects. After the lithium battery sheets are broken, these sheet materials need to undergo a series of processing to extract the lithium in the sheet materials for reuse, achieving the purpose of recycling waste batteries.

[0004] Due to the soft and other characteristics of sheet-shaped battery raw materials, when they are stacked after feeding, they have a certain degree of adhesion and irregularity. When passing through the feeding channel to the feeding bin opening, they often accumulate, resulting in unsmooth feeding. During the process from the storage bin to the feeding bin opening, a bridging phenomenon is likely to occur, causing the sheet-shaped battery raw materials to get stuck and unable to be evenly and continuously fed, which will affect automated production.

Detailed Embodiments

[0028] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0029] Embodiment 1

[0030] As Figure 1As shown in the figure, the feeding mechanism for recycling sheet lithium battery raw materials of the present utility model includes a rotating device and a driving device for driving the rotating device to swing or rotate regularly back and forth. Among them, the rotating device is arranged inside the feeding channel 1 and includes a rotor core 2 and four blades 3. The four blades 3 are respectively connected to the rotor core 2 and are evenly distributed along the circumferential direction of the rotor core 2. The driving device is connected to the rotor core 2 to drive the rotor core 2 to rotate reciprocally or rotate, so as to realize the regular swinging or rotating back and forth of the four blades 3 to disperse the stacked sheet lithium battery raw materials 4 in the feeding channel 1.

[0031] In this embodiment, the rotor core 2 is detachably installed on the inner wall of the feeding channel 1, and the axial direction of the rotor core 2 is perpendicular to the feeding direction of the sheet lithium battery raw materials 4 in the feeding channel 1.

[0032] In addition, the driving device includes a motor 5, a transmission component (not shown), a rotating shaft (not shown) and a swinging component. Among them, the swinging component includes a connecting rod 6, a rotating arm 7 and a swing arm plate 8. The rotating arm 7 is connected to the rotating shaft, the swing arm plate 8 is connected to the rotor core 2, and the two ends of the connecting rod 6 are respectively connected to the rotating arm 7 and the swing arm plate 8. The motor 5 is connected to the rotating shaft through the transmission component to drive the rotating shaft to rotate, so as to drive the rotor core 2 to rotate through the swinging component. During operation, the motor 5 drives the rotor core 2 to rotate reciprocally in a way of switching between forward and reverse, driving the four blades 3 on the rotor core 2 to swing regularly back and forth.

[0033] During the working process of the feeding mechanism for recycling sheet lithium battery raw materials in this embodiment, when the swing arm plate 8 swings back and forth at a certain angle, the sheet lithium battery raw materials 4 will first enter the space between the blade 3 and the inner wall of the feeding channel 1, and then the blade 3 will send this part of the sheet lithium battery raw materials 4 downward to achieve the feeding effect. The feeding amount is determined by the size of the space between the blade 3 and the inner wall of the feeding channel 1. The faster the rotation speed of the motor 5, the faster the swing, and the larger the feeding amount per unit time. When the rotation radius of the connecting rod 6 and the rotating arm 7 is large enough, the reciprocating motion of the swing arm plate 8 can also be realized. Here, it is better to realize the back-and-forth swing of the swing arm plate 8.

[0034] This embodiment adopts the structure that the rotating arm 7 drives the swing arm plate 8 to swing through the connecting rod 6. Combined with the beating of multiple blades 3, the feeding amount of the sheet lithium battery raw materials 4 can be controlled by setting the length and rotation speed of the swing arm plate 8.

[0035] Embodiment Two

The two driving devices in this embodiment have the same structure as the driving device in Embodiment One and are respectively connected to the rotor cores 2 of the corresponding rotating devices.

[0037] To increase the airtightness, an air inlet 9 for injecting protective gas and an air outlet 10 for discharging replacement gas are provided in the material discharging channel 1 between the two rotating devices. In this embodiment, a double reciprocating swing blade structure is adopted to realize the dispersion and uniformity of the feeding of the sheet-shaped lithium battery raw material 4 in the upper and lower layers.

[0038] Embodiment III

[0039] As Figure 3 shown, the sheet-shaped lithium battery raw material recovery and feeding mechanism of this embodiment includes two rotating devices and two driving devices. The two rotating devices in this embodiment have the same structure as the rotating device in Embodiment I, and the two rotating devices are arranged side by side in the direction perpendicular to the feeding direction.

[0040] The driving device of this embodiment includes a motor and a driving shaft. The driving shaft is connected to the rotor core 2, and the motor is connected to the driving shaft to realize driving the rotor core 2 to rotate through the driving shaft, so as to drive the blades 3 on the rotor core 2 to rotate.

[0041] In this embodiment, two driving devices can be provided, and the two driving devices are respectively connected to the rotor cores 2 of the corresponding rotating devices. In this embodiment, one driving device can also be provided. The sheet-shaped lithium battery raw material recovery and feeding mechanism further includes a driven structure. The driving device is connected to the rotor core 2 of one of the rotating devices and is connected to the rotor core 2 of the other rotating device through the driven structure.

[0042] In this embodiment, the left rotating device can be driven to rotate clockwise and the right rotating device to rotate counterclockwise through the driving device. Because of the rotating force of the blades 3, the sheet-shaped lithium battery raw material 4 can be fed through the rotation of the two rotating devices. The faster the rotation speed, the faster the feeding.

[0043] Embodiment IV

[0044] As Figure 4 、 Figure 5 and Figure 6 shown, the difference between this embodiment and Embodiment III is that when the two rotating devices are arranged side by side in the direction perpendicular to the feeding direction, the sheet-shaped lithium battery raw material recovery and feeding mechanism of this embodiment is provided with an auxiliary rotating device 11 and an auxiliary driving device above and / or below the two side-by-side arranged rotating devices. The auxiliary rotating device 11 has the same structure as the rotating device in Embodiment III and is connected to the auxiliary driving device. The auxiliary driving device of this embodiment has the same structure as the driving device in Embodiment III.

[0045] The design of this embodiment can achieve a better effect of dispersing and uniformizing the sheet-shaped lithium battery raw material, achieving the purpose of dispersed and uniform feeding. The control of the feeding amount in the solution of this embodiment is more accurate than that in the solution of Embodiment III, and the feeding speed can be controlled according to requirements.

[0046] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
