[0027] Example
[0028] ① Generally, screen structures with different screening levels are used for screening. However, after the screen structure has been used for a long time, it is not easy to disassemble it for cleaning or replacement;
[0029] ② The second aspect is that the screen structure often performs screening in a static manner. If the input amount or the number of batteries is large, it is easy to cause the batteries to accumulate on the screen structure, thereby greatly reducing the efficiency of screening and classification;
[0030] To do this, see Figure 1-4 The utility model provides a pre-classification device in the process of recycling and reusing waste lithium batteries, comprising: a sorting frame 1, a movable opening a2 and a movable opening b3 are respectively opened on the two side walls of the sorting frame 1, a screening frame a21 and a screening frame b31 are respectively slidably arranged on the movable opening a2 and the movable opening b3, a screen a22 and a screen b32 are respectively fixedly arranged on the inner walls of the screening frame a21 and the screening frame b31, and a guide is respectively connected to the one side wall of the screening frame a21 and the screening frame b31 through a latch clamping structure 4.

[0031] It also includes a reciprocating transmission structure 5, which is installed on the guide seat a24 and the guide seat b34 and is connected to the sorting frame 1. The reciprocating transmission structure 5 can facilitate the synchronous reciprocating movement of the screening frame a21 and the screening frame b31, greatly improving the screening efficiency;
[0032] Among them, the width of the screening box a21 is smaller than the width of the screening box b31, and the width of the screen a22 is smaller than the width of the screen b32. In addition, the setting of the discharge port a23 is to allow the large batteries that have not passed the screening to fall into the screening box b31, and the setting of the discharge port b33 is to allow the largest batteries that have not passed the final screening to fall into the receiving box 6.
[0033] Further as Figure 1-4 As shown, it is worth explaining in detail that in order to facilitate the disassembly and assembly of the screening frame a21 or the screening frame b31, a pin clamping structure 4 is provided, including a pin block 41 fixed on a side wall of the screening frame a21 or the screening frame b31, and the pin block 41 is movably inserted in the socket provided on the guide seat a24 or the guide seat b34. A T-shaped column 42 is movably inserted in the socket 45 provided at one end of the pin block 41, and a limit block 43 is movably sleeved on the outer side of the T-shaped column 42. One end of the limit block 43 is fixed to the outer side of the guide seat a24 or the guide seat b34, and the end of the limit block 43 away from the socket 45 is connected to the end of the T-shaped column 42 away from the socket 45 through a spring 44, and the spring 44 is movably sleeved on the outer side of the T-shaped column 42.
[0034] The depth of the insertion hole 45 is equal to the thickness of the limiting block 43 .
[0035] Further as Figure 1-4 As shown, it is worth explaining in detail that in order to enable the screening frame a21 and the screening frame b31 to move back and forth simultaneously, a reciprocating transmission structure 5 is set, including a push-pull rod 51 fixed at one end of the guide seat a24 and the guide seat b34, and the other ends of the two push-pull rods 51 are movably extended to the outside of the sorting frame 1, and are fixed with the same linkage rod 52, and the linkage rod 52 is movably sleeved on the outside of the transmission column 53 through the transmission channel opened thereon, and the bottom end of the transmission column 53 is fixed to the top surface edge of the turntable 54, the turntable 54 is fixed to the outside of the output shaft of the motor 55, and the motor 55 is fixed to the rear side wall of the sorting frame 1.
[0036] The length of the transmission channel is greater than the diameter of the turntable 54 , and the width of the transmission channel is equal to the diameter of the transmission column 53 .
[0037] In summary: when using the pre-sorting device in the process of recycling and reusing waste lithium batteries, first introduce the batteries to be screened into the screening frame a21, and by starting the motor 55, the turntable 54 drives the transmission column 53 to rotate, and cooperates with the setting of the transmission channel, so that the linkage rod 52 drives the two push-pull rods 51 to move back and forth, so that the guide seat a24 and the guide seat b34 move back and forth, so that the screening frame a21 and the screening frame b31 can move back and forth, and the small batteries are screened by the screen a22 and discharged from the discharge channel a25. In addition, the large batteries that have not passed the screen a22 slide into the screening frame b31 through the discharge port a23 for re-screening, and follow the aforementioned discharge steps, thereby greatly improving the screening efficiency of the batteries.
