This electrolyte is neither completely liquid nor completely solid, but a "semi-solid" state between the two.

[0044] The specific configuration and functions of the driving structure 4, the positioning structure 5 and the adjusting structure 6 are described in detail below.

[0045] like Figure 1-Figure 7As shown, the support frame 403 is internally rotatably connected with a screw rod 409, the screw rod 409 and the pressure strip 410 are internally threadedly connected, and the upper end of the screw rod 409 is fixedly connected with a first rotating block 412. By twisting the first rotating block 412, the screw rod 409 can be driven to rotate, and the pressure strip 410 can be driven during the screw rod 409. The lower surface of the pressure strip 410 is glued with an elastic strip 411, and the lower end side of the elastic strip 411 is an arc surface structure. The elastic strip 411 with an arc structure on the bottom side is provided to improve the squeezing effect on the semi-solid lithium battery body 7, avoid the phenomenon that the plastic film is scratched, and the elastic strip 411 and the semi-solid lithium battery body 7 have relative movement, thereby facilitating the work of driving out bubbles between the semi-solid lithium battery body 7 and the plastic film. The cross section of the rack frame 402 is "U" shaped, and two auxiliary plates 414 are fixedly connected to the end side of the rack frame 402. The two auxiliary plates 414 are open on one side away from the rack frame 402. By providing the auxiliary plates 414 with open structures on both sides, it is convenient to pass the gear 406 inside the rack frame 402.

[0046] like Figure 1-Figure 4 As shown, the internal thread of the moving block 55 is connected to two sliders 53, and the end sides of the two sliders 53 are fixedly connected to the limit plate 52, and the cross section of the limit plate 52 is an isosceles trapezoid. By setting the limit plate 52 with an isosceles trapezoidal cross section, it is convenient to insert the semi-solid lithium battery body 7 between the two limit plates 52. The two ends of the bidirectional screw 51 are fixedly connected to the second rotating block 56. When the second rotating block 56 is rotated, the second rotating block 56 will drive the bidirectional screw 51 to rotate inside the support frame 408.

[0047] 7. A plastic film packaging device for producing a semi-solid lithium battery according to claim 5, characterized in that: a first spring 54 is fixedly connected between the limit plate 52 and the moving block 55. The effect achieved by the above components is that the limit plate 52 is pressed against the side wall of the semi-solid lithium battery body 7 by the elastic force of the first spring 54.

[0048] like Figure 1-Figure 2 and Figure 5-Figure 8 As shown, the end side of the limit bar 61 is provided with an inclined surface 64. The inclined surface 64 of the limit bar 61 will move relative to the second tooth block 415, so as to realize the pressure-driving work of the second tooth block 415. A threaded hole 65 is provided on the surface of the limit bar 61, and a bolt 66 is threadedly connected to the inner side of the threaded hole 65. By rotating the bolt 66 on the inner side of the threaded hole 65 and clamping the bolt 66 in the position between the adjacent second tooth blocks 415, the subsequent serious sliding of the limit bar 61 can be avoided. A second spring 63 is fixedly connected between the second tooth block 415 and the rack frame 402. When the limit bar 61 is pulled out from the surface of the second tooth block 415, the second tooth block 415 will be moved to the side close to the limit bar 61 by the elastic force of the second spring 63.

[0049] Working principle: After the plastic film is put on the semi-solid lithium battery body 7, the semi-solid lithium battery body 7 is placed between the pressure strip 410 and the support frame 408. The screw rod 409 can be driven to rotate by twisting the first rotating block 412. The pressure strip 410 can be driven during the rotation of the screw rod 409. The pressure strip 410 will drive the elastic strip 411 to stick to the surface of the semi-solid lithium battery body 7. In the process of transmitting the semi-solid lithium battery body 7, the support frame 403 will move through the rack frame 402. By setting the auxiliary plate 414 with the structure opened on both sides, the passing of the gear 406 on the inner side of the rack frame 402 is facilitated. The gear 406 is on the inner side of the "U"-shaped rack frame 402, which improves the first gear on the rack frame 402. The meshing effect between the second tooth block 415 and the first tooth block 413 on the gear 406 can realize the driving and rotating work of the gear 406 during the relative movement between the first tooth block 413 and the second tooth block 415. The gear 406 can rotate relative to the support frame 403 with the help of the rotating pin 405, thereby facilitating the driving and rotating work of the semi-solid lithium battery body 7 inside the oven 3, and can make the plastic film on the surface of the semi-solid lithium battery body 7 uniformly thermoplastic during the movement of the semi-solid lithium battery body 7. In the process of rotating the semi-solid lithium battery body 7, the elastic strip 411 abutting against the surface of the semi-solid lithium battery body 7 will move relative to the semi-solid lithium battery body 7. By setting the elastic strip 411 with an arc-shaped bottom side, The squeezing effect on the semi-solid lithium battery body 7 is improved, and the phenomenon of the plastic film being scratched is avoided. The elastic strip 411 and the semi-solid lithium battery body 7 have relative movement, so that it is convenient to drive out the bubbles between the semi-solid lithium battery body 7 and the plastic film, and further improve the thermoplastic effect of the semi-solid lithium battery body 7. The first rotating block 412 can be rotated to realize the driving rotation of the screw rod 409. The screw rod 409 will drive the pressure strip 410 to move up and down on the inner side of the support frame 403, which is convenient for adjusting the pressure on the plastic film on the semi-solid lithium battery body 7, further improving the squeezing effect of the bubbles between the plastic film on the surface of the semi-solid lithium battery body 7 and the semi-solid lithium battery body 7, and improving the plastic film on the surface of the semi-solid lithium battery body 7. The supporting frame 403 is connected to the conveyor belt 2 by means of the rubber plate 404, so that the toughness of the supporting frame 403 when passing through the bending position of the conveyor belt 2 can be avoided, and the supporting plate can be avoided from being easily broken when passing through the bending section of the conveyor belt 2. In addition, the lower side of the multiple rubber plates 404 is large in space, which improves the stability of the supporting frame 403 during movement. By setting the driving and rotating structure 4, the semi-solid lithium battery body 7 is driven and rotated during the transmission process, which not only realizes the uniform heating of the plastic film on the surface of the semi-solid lithium battery body 7, but also facilitates the extrusion and bubble removal work of the plastic film position on the surface of the semi-solid lithium battery body 7, and improves the thermoplastic efficiency of the plastic film on the surface of the semi-solid lithium battery body 7 to a certain extent.

[0050] When it is necessary to place the semi-solid lithium battery body 7, the second rotating block 56 can be rotated, and the second rotating block 56 will drive the bidirectional screw 51 to rotate on the inner side of the support frame 408. At this time, the two moving blocks 55 can be adjusted to be close to each other or away from each other at the same time, which is convenient for positioning the semi-solid lithium battery bodies 7 of different sizes, and further improves the effect of uniform heating of the plastic film on the surface of the semi-solid lithium battery body 7 during movement. The product is placed between the two limiting plates 52. By setting the limiting plate 52 with an isosceles trapezoidal cross-section, it is convenient to insert the semi-solid lithium battery body 7 between the two limiting plates 52. After the semi-solid lithium battery body 7 is inserted between the two limiting plates 52, the limiting plates 52 will be affected. The elastic force of the first spring 54 is pressed against the side wall of the semi-solid lithium battery body 7, which facilitates the tight positioning of the semi-solid lithium battery body 7. The sliding of the slider 53 inside the moving block 55 plays a role in limiting the moving direction of the limit plate 52. The semi-solid lithium battery body 7 is squeezed and limited by the limit plate 52, which improves the tightness of the limitation of the semi-solid lithium battery body 7, avoids the phenomenon of the semi-solid lithium battery body 7 moving a long distance during the rotation process, and further improves the rotation effect of the semi-solid lithium battery body 7. By setting the positioning structure 5, the positioning of the semi-solid lithium battery body 7 is facilitated, the stability of the semi-solid lithium battery body 7 during the movement process is improved, and the normal operation of the driving structure 4 is facilitated.

[0051] The slide bar 62 on the inner side of the sliding rack frame 402 can realize the movement of the limit bar 61 during the sliding process. When the limit bar 61 is pulled out from the surface of the second tooth block 415, the second tooth block 415 will be moved to the side close to the limit bar 61 by the elastic force of the second spring 63. At this time, the second tooth block 415 will not move relative to the first tooth block 413 after being pulled out for a distance. On the contrary, in the process of moving the limit bar 61, the inclined surface 64 of the limit bar 61 will move relative to the second tooth block 415, so as to realize the pressure driving work of the second tooth block 415. After the second tooth block 415 is squeezed out from the inner side of the rack frame 402, the second tooth block 415 will move relative to the first tooth block 413, which facilitates the flexible control of the rotation angle of the gear 406. The rotation angle of the control gear 406 can control the semi-solid lithium The final rotational position of the battery body 7 rotates the semi-solid lithium battery body 7 to a position that is convenient for the staff to take out, which facilitates the subsequent removal of the semi-solid lithium battery body 7 according to the staff's habits, and improves the efficiency of removing the semi-solid lithium battery body 7 after the surface plastic film is applied. After moving the limit bar 61 to a suitable position, rotate the bolt 66 on the inner side of the threaded hole 65, and clamp the bolt 66 in the position between the adjacent second tooth blocks 415, which can avoid the subsequent serious sliding of the limit bar 61. By setting the adjustment structure 6, it is convenient to flexibly adjust the number of second tooth blocks 415 on the inner side of the rack frame 402, and it is convenient to flexibly adjust the position of the semi-solid lithium battery body 7 after plastic film processing, so as to facilitate the staff to remove the semi-solid lithium battery body 7 according to the removal habits, and further improve the plastic film processing performance of the semi-solid lithium battery body 7.
