[0039] In the embodiment, when the lithium strip cutting and thinning device is used, first, the lithium strip cylinder 9 wound with the lithium strip is sleeved and installed on the penetrating cylinder rod 8, the lithium strip is sequentially led out from the lithium strip cylinder 9, passes through the installation plate 6, the strip guiding mechanism, the lithium strip rolling mechanism, the clamping and conveying mechanism at the feeding position, the cutting mechanism and the clamping and conveying mechanism at the discharging position.

[0040] After the device is started, the two clamping and conveying mechanisms (i.e. the clamping and conveying mechanisms at the feeding position and the discharging position) synchronously and intermittently clamp and move the lithium strip, the lithium strip is first rolled by the lithium strip rolling mechanism during the movement process to ensure that the lithium strip is flat, then enters the cutting mechanism, the two clamping and conveying mechanisms are located on the two sides close to the cutting mechanism, and cooperate to clamp and displace the lithium strip, so that the deformation of the lithium strip is greatly reduced, and the cutting quality is improved. The cutting cylinder 5 pushes the cutting male die 4 to move downward to cooperate with the cutting female die 3 to complete the cutting of the lithium strip.

[0041] The lithium strip waste after cutting is continuously conveyed by the clamping and conveying mechanism, the lithium strips before and after cutting are respectively controlled to move by the clamping and conveying mechanisms on the two sides to ensure the continuous conveying and cutting of the lithium strip, the displacement of the lithium strip and the cutting are alternately performed to ensure that they do not affect each other.

[0042] The lithium strip cutting and thinning device is provided with a lithium strip rolling mechanism, which rolls the lithium strip to ensure that the lithium strip is flat before cutting, thereby improving the cutting accuracy and reducing the cutting error. The clamping and feeding mechanism and the cutting mechanism are alternately and synchronously operated and are respectively located on the two sides of the cutting mechanism, which can intermittently clamp and move the lithium strip to ensure the neatness of the lithium strip during the cutting process and avoid deformation or deviation of the lithium strip during the transmission process. The whole device realizes the automatic cutting and conveying of the lithium strip, reduces the manual intervention, improves the production efficiency, and at the same time, the cutting female die 3 and the cutting male die 4 are designed to be detachable, which is convenient for replacement and maintenance, and further improves the production flexibility.

[0043] In a further preferred embodiment of the present application, a guide shaft rod one 10 is rotatably mounted on the mounting plate 6 for guiding the lithium strip, and a strip passing opening 11 is formed on the mounting plate 6 for the lithium strip to pass through.

[0044] In this embodiment, after the lithium strip is drawn out from the lithium strip cylinder 9, it first passes through the guide shaft rod one 10 and the strip passing opening 11 on the mounting plate 6, and then continues to advance along the transmission path of the device. The design of the strip passing opening 11 ensures that the lithium strip can accurately and correctly enter the subsequent guide mechanism and lithium strip rolling mechanism, further ensuring the transmission stability of the lithium strip before cutting. In this way, the lithium strip can always maintain a flat and stable transmission state before entering the cutting mechanism, providing a good basis for the subsequent cutting process.

[0045] In a further preferred embodiment of the present application, the guide mechanism includes a shaft support 12 fixedly installed on the top of the support table 1, the shaft support 12 is located between the mounting plate 6 and the lithium strip rolling mechanism, and a plurality of guide shaft rods two 13 are rotatably mounted on the shaft support 12 for guiding the lithium strip to the corresponding clamping and feeding mechanism for feeding, and the heights of the plurality of guide shaft rods two 13 are staggered.

[0046] In this embodiment, the guide mechanism includes a shaft support 12 fixedly installed on the top of the support table 1, and the shaft support 12 is located between the mounting plate 6 and the lithium strip rolling mechanism. A plurality of guide shaft rods two 13 with staggered heights are rotatably mounted on the shaft support 12, and the lithium strip is guided to the corresponding clamping and feeding mechanism for feeding in sequence through these guide shaft rods two 13. This multi-stage guiding design ensures that the lithium strip always maintains a stable and accurate transmission path before entering the cutting mechanism, providing a good basis for the subsequent cutting and rolling processes.

[0047] The present application further optimizes the transmission path of the lithium strip by providing a plurality of guide shaft rods two 13 with staggered heights in the guide mechanism. The staggered heights of the plurality of guide shaft rods two 13 allow the lithium strip to evenly distribute tension during transmission, avoiding deformation or damage of the lithium strip due to concentrated tension.

[0048] The further preferred embodiment of the present application is that the shaft support 12 is fixedly provided with a stabilizing guide rod 14, the stabilizing guide rod 14 and the plurality of guide belt shaft rods two 13 are sleeved with two width limiting pieces 15, the shaft support 12 is rotatably provided with a bidirectional screw rod one 16, the bidirectional screw rod one 16, the stabilizing guide rod 14 and the guide belt shaft rod two 13 are arranged in parallel, the two thread sections with opposite rotation directions of the bidirectional screw rod one 16 are respectively threaded through the two width limiting pieces 15, and the width limiting pieces 15 are driven to move close to or away from each other, so that the passing lithium belt is limited and guided to prevent deviation.

[0049] In the embodiment, when the lithium belt passes through the guide belt mechanism, it is guided by the plurality of guide belt shaft rods two 13 on the shaft support 12. The shaft support 12 is fixedly provided with a stabilizing guide rod 14, and the stabilizing guide rod 14 and the guide belt shaft rod two 13 are sleeved with two width limiting pieces 15. By rotating the bidirectional screw rod one 16, the two thread sections with opposite rotation directions of the bidirectional screw rod one 16 are respectively threaded through the two width limiting pieces 15, and the width limiting pieces 15 can be driven to move close to or away from each other. In actual operation, according to the width of the lithium belt, the bidirectional screw rod one 16 is adjusted, the distance between the two width limiting pieces 15 is matched with the width of the lithium belt, so that the lithium belt is limited and guided, the deviation of the lithium belt in the transmission process is prevented, and it is ensured that the lithium belt can accurately enter the subsequent cutting and rolling processes.

[0050] The present application further optimizes the guiding accuracy of the lithium belt by providing the stabilizing guide rod 14, the bidirectional screw rod one 16 and the width limiting piece 15 on the shaft support 12. The design of the bidirectional screw rod one 16 allows the distance between the two width limiting pieces 15 to be adjusted by simple knob operation, thereby adapting to lithium belts of different widths. This adjustable limiting and guiding function can effectively prevent the lithium belt from deviating during transmission, ensuring that the lithium belt always remains on the correct transmission path. In this way, not only the transmission stability of the lithium belt is improved, but also the cutting accuracy is further improved, the cutting error is reduced, and the reliability and adaptability of the entire device are improved, so that it can be applied to lithium belt production requirements of different specifications.

[0051] The further preferred embodiment of the present application is that the lithium belt rolling mechanism includes a main roller frame 17 fixedly installed on the top of the support table 1, the main roller frame 17 is located between the shaft support 12 and the corresponding position of the clamping and conveying mechanism, a lower roller 18 is rotatably installed in the main roller frame 17, the upper surface of the lower roller 18 is located on the same horizontal line as the upper surface of the cutting master mold 3, an adjusting cylinder 19 is fixedly installed on the top of the main roller frame 17, a sub-roller frame 20 is fixedly installed on the output rod of the adjusting cylinder 19, the top of the sub-roller frame 20 is fixedly connected with the output rod of the adjusting cylinder 19, the sub-roller frame 20 can slide up and down in the main roller frame 17, and an upper roller 21 is rotatably installed in the sub-roller frame 20. The gap between the upper roller 21 and the lower roller 18 is adjusted by the adjusting cylinder 19, so that the passing lithium belt is rolled.

[0052] In this embodiment, the lithium strip is guided through the guide mechanism and then enters the lithium strip rolling mechanism for rolling treatment. The lithium strip rolling mechanism includes a main roller frame 17 fixedly installed on the top of the support table 1, a lower roller 18 rotatably installed in the main roller frame 17, and the upper surface of the lower roller 18 is located on the same horizontal line as the upper surface of the cutting master mold 3. An adjusting cylinder 19 is fixedly installed on the top of the main roller frame 17, a sub-roller frame 20 is fixedly installed on the output rod of the adjusting cylinder 19, and an upper roller 21 is rotatably installed in the sub-roller frame 20. By the extension and retraction action of the adjusting cylinder 19, the sub-roller frame 20 is controlled to slide up and down in the main roller frame 17, so as to adjust the gap between the upper roller 21 and the lower roller 18. When the lithium strip passes through the gap between the upper roller 21 and the lower roller 18, it is rolled flat, ensuring that the lithium strip maintains good flatness before entering the cutting mechanism, providing high-quality lithium strip for the subsequent cutting process.

[0053] The present application sets up a lithium strip rolling mechanism, which uses the upper roller 21 and the lower roller 18 to roll the lithium strip, ensuring that the lithium strip remains flat before cutting. The design of the adjusting cylinder 19 allows the gap between the upper roller 21 and the lower roller 18 to be adjusted flexibly according to the thickness of the lithium strip and the required flatness, thereby adapting to lithium strips of different specifications. This adjustable rolling mechanism not only effectively repairs the deformation of the lithium strip that may occur during transmission, but also improves cutting accuracy and reduces cutting errors, further improving the production efficiency and product quality of the entire device. In addition, the setting of the rolling mechanism also enhances the transmission stability of the lithium strip, avoids wrinkles or deviation of the lithium strip during cutting, and improves the reliability and consistency of production.

[0054] In a further preferred embodiment of the present application, a discharge shaft 22 is rotatably installed on the top of the discharge side of the support table 1, and the upper surface of the discharge shaft 22 is located on the same horizontal line as the upper surface of the cutting master mold 3, for guiding the cut lithium strip waste out.

[0055] In this embodiment, the cut lithium strip waste is conveyed to the discharge side of the support table 1 by the clamping and conveying mechanism. On the top of the discharge side of the support table 1, a discharge shaft 22 is rotatably installed, and the upper surface of the discharge shaft 22 is located on the same horizontal line as the upper surface of the cutting master mold 3. The cut lithium strip waste is guided through the discharge shaft 22 and smoothly guided out of the device. In this way, the lithium strip waste can be effectively discharged after cutting, avoiding accumulation inside the device, and ensuring smooth production throughout the process.

[0056] In a further preferred embodiment of the present application, a discharge shaft 22 is rotatably installed on the top of the discharge side of the support table 1, and the upper surface of the discharge shaft 22 is located on the same horizontal line as the upper surface of the cutting master mold 3, for guiding the cut lithium strip waste out.

[0057] In this embodiment, a conveyor belt 23 is arranged below the cutting master die 3 to receive the lithium strip raw material cut from the cutting master die 3. The conveyor belt 23 is driven by a conveyor motor 24 to ensure smooth and continuous operation. The conveyor belt 23 is fixed to the top of the support table 1 by a support to ensure its stability during operation. When the lithium strip is cut by the cutting mechanism, the cut lithium strip raw material falls onto the conveyor belt 23, which then transports it to the subsequent process or collection area, thereby achieving automatic transportation of the lithium strip raw material.

[0058] In a further preferred embodiment of the present application, a limiting ring 25 is detachably sleeved on one end of the penetrating cylinder rod 8 inserted into the lithium strip cylinder 9, and the limiting ring 25 is pressed against the side of the lithium strip cylinder 9 sleeved on the penetrating cylinder rod 8, so as to fix the penetrating cylinder rod 8 and the lithium strip cylinder 9.

[0059] In this embodiment, in order to ensure that the lithium strip cylinder 9 can be stably installed on the penetrating cylinder rod 8, a limiting ring 25 is detachably sleeved on one end of the penetrating cylinder rod 8 inserted into the lithium strip cylinder 9. When installing the lithium strip cylinder 9, first sleeve the lithium strip cylinder 9 on the penetrating cylinder rod 8, then sleeve the limiting ring 25 on the end of the penetrating cylinder rod 8, and press it against the side of the lithium strip cylinder 9. In this way, the limiting ring 25 can firmly fix the lithium strip cylinder 9 on the penetrating cylinder rod 8, preventing the lithium strip cylinder 9 from loosening or slipping during transmission, thereby ensuring that the lithium strip can be stably drawn out of the lithium strip cylinder 9 and into the subsequent strip guiding mechanism and cutting mechanism. This detachable limiting ring 25 not only facilitates installation and removal, but also improves the installation efficiency of the lithium strip cylinder 9, reducing the problem of lithium strip transmission interruption or jamming caused by loose installation. In addition, the use of the limiting ring 25 also enhances the operation reliability of the entire device, further improving the production efficiency and product quality.

[0060] In a further preferred embodiment of the present application, a plurality of pressing rods 27 are fixedly installed on the pressure ring bolt 26 in a circular array at the threaded end of the penetrating cylinder rod 8, and the ends of the plurality of pressing rods 27 abut against the limiting ring 25.

[0061] In this embodiment, in order to further enhance the fixing effect of the limiting ring 25 on the lithium strip cylinder 9, a pressure ring bolt 26 is threadedly installed at the insertion end of the penetrating cylinder rod 8. A plurality of pressing rods 27 are fixedly installed on the pressure ring bolt 26 in a circular array, and the ends of these pressing rods 27 abut against the limiting ring 25. During installation, after the lithium strip cylinder 9 is sleeved on the penetrating cylinder rod 8, the limiting ring 25 is sleeved, and then the pressure ring bolt 26 is tightened, firmly pressing the limiting ring 25 against the side of the lithium strip cylinder 9 through the pressing rods 27, thereby ensuring the stability of the lithium strip cylinder 9 on the penetrating cylinder rod 8. This design enables the lithium strip cylinder 9 to remain stable during operation, avoiding loosening or slipping due to vibration or external force.

[0062] In a further preferred embodiment of the present application, the plurality of pressing rods 27 are arranged in a circular array with a diameter larger than that of the penetrating rod 8 and smaller than that of the limiting ring 25, and the pressing rods 27 are inserted to avoid the penetrating rod 8.

[0063] In this embodiment, the plurality of pressing rods 27 are arranged in a circular array with a diameter larger than that of the penetrating rod 8 and smaller than that of the limiting ring 25. This design allows the pressing rods 27 to accurately avoid the penetrating rod 8 during installation and directly act on the outer surface of the limiting ring 25. When the pressing ring bolt 26 is tightened, the pressing rods 27 uniformly apply pressure to the limiting ring 25 through their ends, ensuring that the limiting ring 25 is firmly pressed against the side of the lithium ribbon canister 9, thereby achieving stable fixation of the lithium ribbon canister 9 on the penetrating rod 8.
