Slitting device for automobile battery aluminum strip production

Abstract

This utility model belongs to the field of automotive battery aluminum strip production technology, specifically relating to slitting equipment for automotive battery aluminum strip production. It includes a slitting machine bracket and a controller mounted on the surface of the slitting machine bracket. A drive motor is connected to the surface of the slitting machine bracket, and a protective plate is connected to the surface of the slitting machine bracket near the drive motor. A lower slitting roller is connected to the inner side of the protective plate, and a linkage gear is connected to one end of the lower slitting roller. An upper slitting roller is located at the top of the lower slitting roller. This utility model places the battery aluminum strip on a feeding support plate and simultaneously rotates a lead screw along the surface of the side plate. This causes a limiting plate at one end of the lead screw to advance along the surface of the feeding support plate. This allows the two limiting plates to limit the feeding of the battery aluminum strip, ensuring feeding stability and preventing deviation. The battery aluminum strip is then slitted using the lower and upper slitting rollers.

Description

Technical Field

[0001] This utility model belongs to the field of automotive battery aluminum strip production technology, specifically relating to slitting equipment for automotive battery aluminum strip production. Background Technology

[0002] Slitting equipment for automotive battery aluminum strip production is a specialized piece of equipment that precisely cuts wide aluminum strips or foils into multiple narrow strips according to a set width. It is mainly used in the production of electrode sheets for power batteries in new energy vehicles (such as current collector aluminum strips). Its core task is to complete the aluminum strip slitting under high-speed and high-precision conditions, ensuring that the cut surface is flat and burr-free, meeting the consistency and safety requirements of battery production.

[0003] Specifically, when using slitting equipment to slit aluminum strips for automotive batteries, if the edge alignment accuracy of the aluminum strip is insufficient during the feeding process, a series of problems may occur: after the aluminum strip is unwound by the unwinding mechanism, if the winding deviation of the coil itself or the unwinding tension is uneven, it may cause a lateral shift before entering the slitting mechanism. This unevenness causes the circular cutter to deviate from the preset trajectory, resulting in a narrow strip width deviation after slitting, and burrs or wavy edges. In severe cases, the aluminum strip may get stuck between the cutter shaft and the guide roller, causing wrinkles or even tears, leading to the scrapping of the entire roll of material. At the same time, the additional tensile impact caused by the offset will accelerate tool wear, shorten the blade life, and significantly increase production costs and downtime for adjustment. Utility Model Content

[0019] Please see Figure 1-5 The present invention provides the following technical solution: a slitting device for producing aluminum strips for automobile batteries, including a slitting machine bracket 1 and a controller 2 installed on the surface of the slitting machine bracket 1. A drive motor 3 is connected to the surface of the slitting machine bracket 1. A guard plate 4 is connected to the surface of the slitting machine bracket 1 near the drive motor 3. A lower slitting roller 5 is connected to the inner side of the guard plate 4. A linkage gear 6 is connected to one end of the lower slitting roller 5. An upper slitting roller 7 is provided at the top of the lower slitting roller 5. A feeding support plate 8 is installed on the back side of the slitting machine bracket 1. A side plate 9 is connected to the surface of the feeding support plate 8. A lead screw 10 is connected through the surface of the side plate 9. A receiving block 11 is connected to the other end of the lead screw 10. A limit plate 12 is connected to the other side of the receiving block 11. A rotating block 13 is connected to the end of the lead screw 10 near the receiving block 11. A positioning plate 14 is connected to one side of the limit plate 12.

[0020] Preferably, the side plate 9 and the lead screw 10 are threaded together, and the limiting plate 12 is made of stainless steel. In actual use, the use of the stainless steel limiting plate 12 facilitates the limiting of the loaded battery aluminum strip and avoids deviation. Preferably, the lead screw 10 forms a rotating structure through the opening on one side of the rotating block 13 and the receiving block 11, and the positioning plate 14 passes through and extends to the outside of the side plate 9, forming a sliding connection structure with the opening on the surface of the side plate 9. In actual use, the positioning plate 14 is slidable along the opening on the surface of the side plate 9 to ensure the stability of the movement of the limiting plate 12.

[0021] Preferably, the top of the feeding support plate 8 is connected to a top plate 15, and four fixing blocks 16 are installed on the bottom surface of the top plate 15.

[0022] Preferably, a buffer spring 17 is connected to the bottom opening of the fixed block 16, and a linkage plate 18 is connected to the other end of the buffer spring 17. A telescopic plate 19 is connected to the other side of the linkage plate 18, and the bottom end of the telescopic plate 19 passes through and extends to the bottom end of the fixed block 16. In actual use, by sliding the telescopic plate 19 up and down inside the fixed block 16, the roller 21 can be automatically adjusted in height.

[0023] Preferably, the bottom end of the telescopic plate 19 is connected to a roller bracket 20, and the inner wall of the roller bracket 20 is connected to a roller 21. In actual use, the roller 21 facilitates auxiliary positioning of the battery aluminum strip and ensures feeding stability.

[0024] The working principle of this utility model is as follows: First, the battery aluminum strip is placed on the feeding support plate 8, and the lead screw 10 is rotated along the surface of the side plate 9. At this time, the limiting plate 12 at one end of the lead screw 10 is pushed forward on the surface of the feeding support plate 8. This facilitates the limiting plates 12 to limit the feeding of the battery aluminum strip, ensuring the stability of the feeding of the battery aluminum strip and avoiding deviation. Then, the control controller 2 starts the drive motor 3, which drives the lower slitting roller 5 and the upper slitting roller 7 to rotate. At the same time, the battery aluminum strip is slid through the use of the lower slitting roller 5 and the upper slitting roller 7. In addition, during the feeding of the battery aluminum strip, the roller 21 inside the roller bracket 20 rolls the surface of the battery aluminum strip. According to different thicknesses, the telescopic plate 19 at the top of the roller bracket 20 slides inside the fixed block 16, and drives the linkage plate 18 to squeeze the buffer spring 17, adapting to battery aluminum strips of different thicknesses and ensuring the slitting effect.
