[0030] Embodiment 1

[0031] Embodiment 1 of the present application provides a lithium battery separator waste collecting device, which is described with reference to Figure 1 and Figure 2The lithium battery diaphragm waste collecting device comprises a collecting box 1, a winding shaft 2 and a deviation rectifying plate 3. The collecting box 1 is hollow inside and used for accommodating the waste. The bottom of the collecting box 1 is provided with universal wheels 11. The collecting box 1 can be moved to any suitable position for collection through the universal wheels 11 at the bottom in use. The universal wheels 11 also have a locking function, so that the collecting box 1 can be stably stayed at the target position. Since the universal wheels 11 belong to the common prior art, the structure is not described here.

[0032] A winding opening 12 is formed in the top of the collecting box 1, and the waste can enter the inside of the collecting box 1 through the winding opening 12. The winding shaft 2 is located inside the collecting box 1, and the winding shaft 2 is placed at a position corresponding to the winding opening 12.

[0033] The winding shaft 2 is horizontally placed, and both ends of the winding shaft 2 are rotationally connected to the inner wall of the collecting box 1. One end of the winding shaft 2 is coaxially fixed with a driven gear (not shown), and the outer wall of the collecting box 1 is provided with a driving servo motor (not shown). The output shaft of the driving servo motor is coaxially fixed with a driving shaft 13, and the driving shaft 13 is also rotationally connected to the collecting box 1. The driving shaft 13 and the winding shaft 2 are placed in parallel and spaced apart. The driving shaft 13 is coaxially fixed with a driving gear (not shown), and the driving gear is engaged with the driven gear, so that the driving servo motor can drive the winding shaft 2 to rotate through a pair of intermeshing gears.

[0034] In order to avoid the phenomenon of knotting when the strip-shaped waste is wound, the deviation rectifying plate 3 is provided with a plurality of deviation rectifying plates 3, which are vertically placed and correspondingly located above the winding shaft 2. All the deviation rectifying plates 3 are spaced apart along the axial direction of the winding shaft 2. The deviation rectifying plates 3 are parallel and spaced apart. The deviation rectifying plate 3 divides the winding opening 12 into a plurality of independent winding channels 14. Each winding channel 14 corresponds to a strip-shaped diaphragm waste. In the embodiment of the application, the deviation rectifying plate 3 is provided with four plates, which divide three winding channels 14. The number of deviation rectifying plates 3 can be increased or decreased according to the actual size of the winding opening 12, and can correspond to the number of strip-shaped wastes.

[0035] During winding, each strip-shaped waste cut off corresponds to pass through an independent winding channel 14 and is finally wound on the winding shaft 2. The deviation rectifying plate 3 limits the movement path of each waste, so that each waste is wound at the same position of the winding shaft 2, effectively avoiding the entanglement and knotting of the waste during winding.

[0036] In order to make the replacement of the winding shaft 2 more convenient, the winding shaft 2 comprises a fixed shaft section and a detachable shaft section, the driven gear is fixed on the fixed shaft section, and the detachable shaft section is detachably connected with the fixed shaft section. The detachable connection can be clamping, so that the fixed shaft section and the detachable shaft section are coaxially fixed and can also be separated, so that the winding shaft 2 can be replaced after collecting the waste materials. The specific detachable connection shaft body is also a prior art, and the focus of the present application is not on this, and will not be described here again. It can be quickly disassembled.

[0037] Further, in order to make the width of each winding channel 14 correspond to the width of the corresponding strip-shaped waste material, each correction plate 3 is horizontally slidably connected at the winding opening 12 of the collecting box 1. Specifically, the two side edges of the correction plate 3 in the vertical direction are fixed with sliding blocks 31, and the inner wall of the collecting box 1 is fixed with guide strips 15 corresponding to the positions of the sliding blocks 31 and horizontally placed, and the side wall of the guide strip 15 facing the sliding block 31 is provided with a sliding groove, and the sliding block 31 is slidably connected in the sliding groove of the guide strip 15, so that the sliding process of the correction plate 3 is more stable.

[0038] Referring to Figure 2 and Figure 3 , further, in order to make the correction plate 3 keep the fixed position after adjustment, the inside of one end of the top of the correction plate 3 is vertically slidably connected with a stopper 4, the stopper 4 is strip-shaped, the stopper 4 is horizontally placed and the two ends of the stopper 4 extend out of the correction plate 3. The two ends of the stopper 4 extending out of the correction plate 3 are fixed with abutting blocks 41, and the bottom of the stopper 4 is provided with a restoring member 32, the restoring member 32 is also located in the inside of the correction plate 3, the restoring member 32 can be a compression spring, the restoring member 32 is vertically placed, and the two ends of the restoring member 32 are respectively abutted with the stopper 4 and the correction plate 3. The top of the stopper 4 is fixed with a pressing block 42, the top end of the pressing block 42 extends out of the correction plate 3 and is vertically slidably connected with the correction plate 3.

[0039] The restoring member 32 is always in a state of being squeezed, and the restoring force generated after the restoring member 32 is deformed under pressure pushes the stopper 4 upward, so that the top surface of the abutting block 41 abuts against the inner wall of the collecting box 1, thereby limiting the movement of the correction block; when it is needed to move the correction block, a downward force can be applied to the pressing block 42 to push the stopper 4 downward, so that the abutting block 41 is separated from the inner wall of the collecting box 1, and at this time the correction block can be moved synchronously.

[0040] In order to further improve the friction between the abutting block 41 and the inner wall of the collecting box 1, the top surface of the abutting block 41 is provided with anti-skid texture 43, which can be a rough surface with many small cylindrical protrusions or serrated protrusions, which can effectively improve the friction and further improve the stability of the correction block.

[0041] Referring to Figure 2Further, an openable material taking door 16 is hinged on one side wall of the collecting box 1, and the material taking door 16 is arranged corresponding to the position of the winding shaft 2, and after the material taking door 16 is opened, the winding shaft 2 is convenient to take and place.

[0042] Further, a storage drawer 17 is horizontally slidably connected to the bottom of the collecting box 1, and the storage drawer 17 can be pulled out. The storage drawer 17 can be used to place the unused winding shaft 2, that is, the detachable shaft segment of the winding shaft 2, so as to facilitate the staff to replace the new shaft segment.

[0043] The implementation principle of the lithium battery diaphragm waste collecting device in the embodiment 1 is that the deviation rectifying plate 3 divides the winding opening 12 into a plurality of independent winding channels 14, each winding channel 14 corresponds to one strip-shaped diaphragm waste to pass through, and during winding, each strip-shaped waste passes through an independent winding channel 14 and is finally wound on the winding shaft 2. The deviation rectifying plate 3 limits the movement path of each waste, so that each waste is wound at the same position of the winding shaft 2, and the entanglement and knotting of the waste during winding is effectively avoided.

[0044] Embodiment 2:

[0045] The difference between the embodiment 2 and the embodiment 1 is that Figure 4 The collecting box 1 is vertically slidably connected with a support rod 5 at the top, and the top end of the support rod 5 is rotatably connected with a horizontal auxiliary guide roller 51. The support rod 5 can be provided with two, and the auxiliary guide roller 51 is horizontally placed and rotatably connected at both ends of the two support rods 5.

[0046] During winding of the waste, the auxiliary guide roller 51 can be used to receive the waste, which is more conducive to the accurate falling of the waste into the collecting box 1. Meanwhile, the support rod 5 can slide up and down to adjust the support height, and a locking piece 52 is sleeved on the support rod 5, which can be a locking nut. The locking piece 52 is threadedly connected with the support rod 5, and only needs to abut the bottom surface of the locking nut against the outer wall of the box to limit the position of the support rod 5.
