A lithium battery cell consists of a positive electrode, a negative electrode, and a separator. The positive and negative electrodes are collectively referred to as pole pieces. To increase the density of the pole piece surface material and ensure consistent thickness, the pole pieces must be rolled after the coating process. This process is called pole piece rolling. Furthermore, a guide device is used to ensure that the rolled piece maintains the correct orientation when entering and exiting the rollers, thereby ensuring product yield and quality.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 As shown, a rolling mill base guide device for lithium battery pole piece production includes two support columns 1. The middle parts of the two support columns 1 are fixedly connected with a rotating mechanism 2, which can drive the pressing mechanism 3 to rotate. The middle part of the rotating mechanism 2 is rotatably connected with the pressing mechanism 3, which can prevent the rolled pieces from stacking. The lower parts of the two support columns 1 are fixedly connected with a connecting mechanism 4, which can facilitate the sliding of the rolled pieces into the upper part of the feeding mechanism 6. The lower parts of the front ends of the outer surfaces of the two support columns 1 are fixedly connected with a bearing component 5, which can support the feeding mechanism 6. The middle parts of the bearing components 5 are fixedly connected with the feeding mechanism 6, which can convey the rolled pieces.

[0024] In order to achieve the purpose of driving the pressing mechanism 3 to rotate, refer to Figure 2The rotating mechanism 2 includes two guide sleeves 21, which can guide the rotation of the rotating shaft 22. The middle parts of the inner cavities of the two guide sleeves 21 are connected to the rotating shaft 22 for common rotation.

[0025] In order to avoid the accumulation of rolled products, see Figure 2 The pressing mechanism 3 includes a plurality of inclined wedge blocks 31 , the lower ends of the outer surfaces of the plurality of inclined wedge blocks 31 are fixedly connected with an arc-shaped rubber strip 32 , and the rear inner cavities of the plurality of arc-shaped rubber strips 32 are rotatably connected with the outer surface of the rotating shaft 22 .

[0026] When the rolled pieces slide out of the discharge port and enter the upper part of the feeding mechanism 6, the arc-shaped rubber strips 32 will press down the conveyed rolled pieces under the weight of the inclined wedge blocks 31 and lay the stacked rolled pieces flat on the upper part of the feeding mechanism 6.

[0027] In order to facilitate the sliding of the rolled piece into the upper part of the feeding mechanism 6, see Figure 3 The connection mechanism 4 includes a rectangular column 41, a connecting plate 42 is fixedly connected to the outer surface of the rectangular column 41, and a semicircular shell 43 is fixedly connected to the front surface of the outer surface of the connecting plate 42.

[0028] When a rolled piece needs to slide into the upper part of the feeding mechanism 6, the rolled piece will slide along the upper part of the outer surface of the connecting plate 42 into the upper part of the feeding mechanism 6, and the semicircular shell 43 will be stuck on the upper part of a sliding roller 62 on the rear side, thereby achieving the purpose of supporting the connecting plate 42.

[0029] In order to achieve the purpose of carrying the feeding mechanism 6, refer to Figure 4 The bearing component 5 includes two bearing frames 51. The inner cavities of the two bearing frames 51 are spaced apart and rotatably connected with a number of guide mechanisms 52, which can guide and protect the rolled pieces during transportation. The lower ends of the outer surfaces of the two bearing frames 51 are fixedly connected with a support seat 53, and the rear end of the outer surface of the support seat 53 is fixedly connected to the lower part of the lower end of the outer surface of the two support columns 1.

[0030] In order to guide and protect the rolled pieces during transportation, refer to Figure 4 The guide mechanism 52 includes a rotating column 521, a shaping roller 522 is rotatably connected to the middle of the outer surface of the rotating column 521, and the rotating column 521 is rotatably connected to the corresponding inner cavity of the supporting frame 51.

[0031] When the rolled piece is transported on the upper portion of the feeding mechanism 6 , the rolled piece that collides with the side wall of the carrying frame 51 will come into contact with the plurality of shaping rollers 522 , thereby driving the plurality of shaping rollers 522 to rotate to offset the collision force.

[0032] In order to achieve the purpose of conveying rolled products, refer to Figure 4The feeding mechanism 6 includes two fixed plates 61. The ends of the outer surfaces of the two fixed plates 61 that are close to each other are commonly spaced and rotatably connected with a number of sliding rollers 62, which can achieve the function of stable transportation of the processed rolled products, and the sliding roller 62 located on the rear side is movably connected to the inner surface of the semicircular shell 43.

[0033] The working principle of the present invention is as follows: the processed lithium battery pole piece will first slide along the upper outer surface of the connecting plate 42 into the upper outer surface of a number of sliding rollers 62. At the same time, when there are stacked rolled pieces entering the upper outer surfaces of the number of sliding rollers 62, the downward pressure of the number of inclined wedge blocks 31 will spread the stacked rolled pieces flat on the upper part of the number of sliding rollers 62 through the arc-shaped rubber strips 32. And when the rolled pieces are conveyed on the upper part of the number of sliding rollers 62, the rolled pieces that collide with the side wall of the supporting frame 51 will contact with the number of shaping rollers 522, thereby driving the number of shaping rollers 522 to rotate to offset the collision force.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
