Specifically, the lithium battery film passes between the two rollers of the roller mechanism, that is, by changing the spacing between the two rollers to achieve the matching needs of films of different thicknesses. To be more specific, the way to change the spacing between the two rollers is generally to manually move the spacing between one of the rollers and the other roller, but this traditional way of adjusting the spacing between the rollers is relatively cumbersome and takes a long time and effort. In addition, the traditional way of adjusting the spacing between the two rollers has a relatively low accuracy. Therefore, it is necessary to propose a fine-tuning roller structure for film material processing to improve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:

[0022] It should be noted that in the production process of lithium battery film, the bumps on the film need to be flattened in the specific production link, and the film needs to be extruded to form a thickness of specific specifications. Among them, the film is mainly formed into a wider strip and passed between two pressing rollers. The thickness of the film is limited by the spacing between the pressing rollers to meet specific specifications. At the same time, the upper and lower end surfaces of the film are respectively extruded by the two pressing rollers to achieve the effect of flattening the bumps. In order to meet the demand that the film needs to have a variety of thickness specifications, the spacing between the two pressing rollers needs to be adjusted. Specifically, the traditional spacing adjustment method is generally to manually adjust the relative position of one of the pressing rollers to achieve the requirement of changing the gap between the two pressing rollers. However, this traditional adjustment method is relatively cumbersome and has a low control over the accuracy of the spacing. For this reason, the present application proposes a fine-tuning pressing roller structure for thin film material processing to adjust the above-mentioned problem.

[0023] like Figures 1 to 3 As shown, a fine-tuning roller structure for processing thin film materials includes a first roller 10, and also includes a second roller 20 arranged on the side of the first roller 10, and a rolling gap 21 for moving the film is formed between the first roller 10 and the second roller 20; in addition, it also includes a coarse adjustment component 30 and a fine adjustment component 40 connected to the coarse adjustment component 30, the coarse adjustment component 30 is connected to the second roller 20, and the coarse adjustment component 30 and the fine adjustment component 40 are both used to adjust the size of the rolling gap 21 between the second roller 20 and the first roller 10.

[0024] In the present embodiment, the lithium battery film is in the shape of a wider strip and is arranged in a horizontal direction. The first pressing roller 10 is located above the film, and the second pressing roller 20 is located below the film, and the first pressing roller 10 is located above the second pressing roller 20, that is, the film moves horizontally through the rolling gap 21, wherein a coarse adjustment component 30 and a fine adjustment component 40 are provided below both ends of the second pressing roller 20, specifically, both ends of the first pressing roller 10 are rotatably connected to the pressing roller frame 101 through bearing seats, and both ends of the second pressing roller 20 are rotatably connected to the upper ends of the two coarse adjustment components 30 through bearing seats, wherein the middle part of the coarse adjustment component 30 is slidably connected to the pressing roller frame 101 in the vertical direction, and the lower end of the coarse adjustment component 30 is fixedly connected to the pressing roller frame 101, and the middle part, the upper end of the coarse adjustment component 30 and the second pressing roller 20 are driven to rise or fall by driving the lower end of the coarse adjustment component 30 to rise or fall, thereby roughly adjusting the rolling gap 21 through the coarse adjustment component 30 The size of the rolling gap 21 is adjusted by the fine-tuning component 40, thereby changing the size of the gap between the first pressing roller 10 and the second pressing roller 20. Compared with the traditional method of manually adjusting the spacing between the first pressing roller 10 and the second pressing roller 20, the utility model has a higher efficiency in adjusting the gap between the first pressing roller 10 and the second pressing roller 20 and a simpler process. In addition, the upper end of the fine-tuning component 40 is slidably abutted against the middle part of the coarse-adjusting component 30, and the lower end is slidably abutted against the lower end of the coarse-adjusting component 30, driving the fine-tuning component 40 to move in the horizontal direction, and the middle part, the upper end and the second pressing roller 20 can be driven to rise or fall by extrusion, so as to achieve the fine-tuning of the size of the rolling gap 21 by the fine-tuning component 40, thereby accurately adjusting the size of the gap between the first pressing roller 10 and the second pressing roller 20. Compared with the traditional method of manually adjusting the spacing between the first pressing roller 10 and the second pressing roller 20, the utility model has a higher accuracy in adjusting the gap between the first pressing roller 10 and the second pressing roller 20 and a simpler process.

[0025] It should be understood that the two ends of the first pressure roller 10 are respectively connected to the pressure roller frame 101, and the two ends of the second pressure roller 20 are respectively connected to the pressure roller frame 101 through the coarse adjustment component 30, that is, the first pressure roller 10 and the second pressure roller 20 are independently arranged and can be adjusted respectively, so as to facilitate the installation and fixation of the first pressure roller 10 and the second pressure roller 20.

[0026] For further reference, Figure 1 and Figure 2 The coarse adjustment component 30 includes a distance adjustment cylinder 31, a sliding plate 32, and a support plate 33 located below the sliding plate 32. The output end of the distance adjustment cylinder 31 is set through the support plate 33 and is connected to the sliding plate 32. The upper end of the sliding plate 32 is rotatably connected to the second pressure roller 20, and the lower end is abutted against the support plate 33. The distance adjustment cylinder 31 is used to drive the sliding plate 32 to move and adjust the distance between the first pressure roller 10 and the second pressure roller 20.

[0027] In this embodiment, the sliding plate 32 is located below the second pressure roller 20, and a bearing seat is provided at the upper end of the sliding plate 32. The second pressure roller 20 is arranged through the bearing seat so that the second pressure roller 20 is rotatably connected to the sliding plate 32. Slide blocks are provided on both sides of the outer side of the sliding plate 32. The roller frame 101 is provided with two slide rails for the slide blocks on both sides. Through the structural arrangement of the slide blocks and the slide rails, the sliding plate 32 is slidably connected to the roller frame 101 in the vertical direction. In addition, the support plate 33 is located below the sliding plate 32, and The upper end surface of the support plate 33 is arranged in abutment with the lower end surface of the sliding plate 32. Specifically, one end of the support plate 33 is fixedly connected to the roller frame 101 with screws, wherein the lower end of the distance adjusting cylinder 31 is fixedly connected to the roller frame 101, and the output end of the distance adjusting cylinder 31 is driven to telescope toward the second roller 20, thereby driving the sliding plate 32 to move, so that the second roller 20 is close to or away from the first roller 10, thereby roughly adjusting the size of the rolling gap 21 and changing the size of the gap between the first roller 10 and the second roller 20.

[0028] In some embodiments, reference Figure 1-3 , also includes a pressure roller motor 34, a fixed plate 35 and a transmission belt 36, the fixed plate 35 is connected to one side of the sliding plate 32, the pressure roller motor 34 is connected to the fixed plate 35, the output end of the pressure roller motor 34 is rotationally connected to a section of the transmission belt 36, and the other section of the transmission belt 36 is rotationally connected to the second pressure roller 20.

[0029] Specifically, the fixed plate 35 is in a U shape, and the fixed plate 35 abuts against the inner side surface of the sliding plate 32, wherein the fixed plate 35 and the sliding plate 32 are bolted and fixed, and the pressure roller motor 34 is bolted and fixed to the fixed plate 35. Specifically, the output end of the pressure roller motor 34 is arranged through the fixed plate 35, and the output end of the pressure roller motor 34 drives the second pressure roller 20 to rotate through the transmission belt 36. Combined with the structural arrangement of the bearing seat, the second pressure roller 20 is rotatably connected to the sliding plate 32, driving the film passing through the rolling gap 21 to move.

[0030] For further reference, Figure 1-3 The fine-tuning assembly 40 includes an inclined surface fine-tuning block 41, and the upper end surface of the inclined surface fine-tuning block 41 is in sliding contact with the sliding plate 32;

[0031] The support plate 33 is provided with an adjustment slope 331 adapted to the slope fine-tuning block. The lower end surface of the slope fine-tuning block 41 is in sliding contact with the support plate 33. The slope fine-tuning block 41 is used to move along the fine-tuning slope to fine-tune the distance between the support plate 33 and the sliding plate 32.

[0032] In this embodiment, reference Figure 2 and Figure 3The inclined plane fine-tuning block 41 is located at the outer side of the sliding plate 32 and above the supporting plate 33, wherein the upper end surface of the supporting plate 33 is provided with a fine-tuning inclined plane, and the inclination angle of the fine-tuning inclined plane is 3-10°. In addition, the lower end surface of the inclined plane fine-tuning block 41 is inclined and matched with the fine-tuning inclined plane, that is, the inclination angle of the lower end surface of the inclined plane fine-tuning block 41 is 3-10°. Specifically, a fine-tuning transmission block is provided on the outer side of the sliding plate 32, and the fine-tuning transmission block is screwed and fixed to the sliding plate 32, and the lower end surface of the fine-tuning transmission block is slidably abutted against the upper end surface of the inclined plane fine-tuning block 41, and the inclination angle of the lower end surface of the inclined plane fine-tuning block 41 is 10°, and the inclination angle of the fine-tuning inclined plane is 10°, and the inclination direction of the inclined plane fine-tuning block 41 is opposite to the inclination direction of the fine-tuning inclined plane, thereby driving the inclined plane fine-tuning block 41 on the fine-tuning inclined plane The first roller 10 and the second roller 20 are moved upward, and the contact surfaces on both sides are provided with an inclination angle, so that the spacing between the inclined surface fine-tuning block 41 and the first pressure roller 10 can be changed, and then the inclined surface of the inclined surface fine-tuning block 41 is moved to drive the fine-tuning transmission block, the sliding plate 32, the second pressure roller 20, the pressure roller motor 34, the fixed plate 35 and the transmission belt 36 to perform synchronous fine-tuning movement. Through the structural setting of the fine-tuning inclined surface and the inclined surface fine-tuning block 41, the size of the gap between the first pressure roller 10 and the second pressure roller 20 can be accurately adjusted, so that the size of the rolling gap 21 can be more accurately changed, so that it can better adapt to films of different thicknesses. At the same time, compared with the traditional method of manually adjusting the spacing between the first pressure roller 10 and the second pressure roller 20, the utility model has higher accuracy in adjusting the gap between the first pressure roller 10 and the second pressure roller 20 and simpler procedures.

[0033] For further reference, Figure 1-3 The fine-tuning assembly 40 further includes a distance measuring component 42 , and the distance measuring component 42 is used to measure the moving distance of the second pressing roller 20 .

[0034] In this embodiment, the distance measuring member 42 can be a distance measuring sensor, which is fixed to the roller frame 101 by screws, that is, the distance measuring member 42 and the support plate 33 are relatively stationary. Through the structural setting of the distance measuring member 42, the moving distance of the distance measuring member 42 can be measured more accurately when performing coarse adjustment or fine adjustment. Combined with the vertical display of the distance measuring member 42, the size of the rolling gap 21 can be adjusted more efficiently.

[0035] For further reference, Figure 1-3 The fine-tuning assembly 40 also includes a fine-tuning member 43 for driving the inclined plane fine-tuning block 41 to move along the fine-tuning inclined plane. The fine-tuning member 43 includes a screw rod 431, a reducer 432 and a handwheel 433. One end of the screw rod 431 is connected to the inclined plane fine-tuning block 41, and the other end is connected to one end of the reducer 432. The other end of the reducer 432 is connected to the handwheel 433.

[0036] In this embodiment, the fine-tuning member 43 also includes two fine-tuning fixing blocks arranged at both ends of the screw rod 431. Specifically, the two ends of the screw rod 431 are respectively provided with fine-tuning fixing blocks, and the fine-tuning fixing blocks are bolted and fixed to the roller frame 101, wherein the reducer 432 is bolted and fixed to the roller frame 101. Further specifically, the fine-tuning fixing blocks are arranged at both ends of the fine-tuning fixing blocks, the inclined plane fine-tuning block 41 is located below the fine-tuning fixing blocks, the screw rod 431 sequentially passes through the fine-tuning fixing blocks, the inclined plane fine-tuning blocks 41, and the fine-tuning fixing blocks, and the screw rod 431 and the fine-tuning fixing blocks are connected by bearing rotation. In addition, the output end of the reducer 432 is transmission-connected to one end of the screw rod 431, and the handwheel 433 is transmission-connected to the input end of the reducer 432. Turning the handwheel 433 allows the reducer 432 to drive the screw rod 431 and the inclined plane fine-tuning block 41 to move closer to or away from the reducer 432, thereby driving the inclined plane fine-tuning block 41 on the fine-tuning inclined plane through the structural setting of the reducer 432, the handwheel 433 and the screw rod 431, and then driving the fine-tuning transmission block, the sliding plate 32, the second pressure roller 20, the pressure roller motor 34, the fixed plate 35 and the transmission belt 36 to perform synchronous fine-tuning movement.

[0037] It needs to be explained that when the screw rod 431 drives the inclined plane fine-tuning block 41 to move, the screw rod 431 performs axial rotation motion, that is, the overall position of the inclined plane fine-tuning block 41 does not move up or down. It is because the lower end face of the inclined plane fine-tuning block 41 and the fine-tuning inclined plane are both provided with an inclination angle that the inclined plane fine-tuning block 41 squeezes the fine-tuning transmission block and the sliding plate 32 to perform fine-tuning movement upward.

[0038] For further reference, Figure 1-3 The fine-tuning assembly 40 also includes a locking member 44 , which is connected to the reducer 432 , and is used to limit the movement of the screw rod 431 in the reducer 432 .

[0039] After coarse adjustment and fine adjustment are performed in sequence, the reducer 432 is locked to prevent the vibration of the equipment during operation from driving the screw 431 to move, thereby causing the inclined plane fine adjustment block 41 to squeeze the fine adjustment transmission block to move, and further causing an error in the size of the rolling gap 21. Therefore, the structural setting of the locking piece 44 provides a certain guarantee for the accuracy of the gap between the first pressure roller 10 and the second pressure roller 20 after adjusting the gap.

[0040] It should be explained that, by means of the structural setting of the fine-tuning component 40 including the locking piece 44, the reducer 432 is locked, which greatly resists the fluctuations generated during the rotation of the first pressure roller 10 and the second pressure roller 20, thereby improving the stability of the rolling gap 21, avoiding the influence of fluctuations during the rotation of the pressure rollers on the gap accuracy, and ultimately improving the accuracy of the gap.

[0041] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0042] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
