This design allows the tension adjusting rod to adjust its position in real time according to the running state of the aluminum foil, dynamically balancing the tensile force and resistance of the material. This effectively prevents wrinkles or breakage caused by tension fluctuations, ensuring that the material maintains a constant tension during the slitting process, thereby improving processing accuracy and yield.

[0018] This invention utilizes a servo motor to drive the active rod to rotate, which in turn drives the third connecting block and the first conveying roller to rotate synchronously via a transmission chain.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example: Please combine Figure 1-5 This embodiment of an aluminum foil slitting device includes a mounting assembly 1, which includes a mounting frame 101. The mounting frame 101 has mounting grooves 102 at its front and rear ends. A connecting frame 103 is fixedly connected to the bottom of the mounting frame 101. A feed roller 104 is rotatably connected within the mounting groove 102 at the front end of the mounting frame 101. The device also includes: Tension adjustment assembly 2 includes a tension adjustment rod 201 that is slidably installed inside the connecting frame 103. The front end of the feed roller 104 is provided with a limiting rod 206 that is rotatably connected inside the mounting frame 101. The limiting rod 206 and the tension adjustment rod 201 are connected by a connecting rod 203. The slitting assembly 3 includes a first conveying roller 304 rotatably connected to the inside of the mounting frame 101, a second conveying roller 306 rotatably connected to the inside of the mounting frame 101 and a blade 310 fixedly connected to the inside of the mounting frame 101 by a fixing bolt 311 on one side of the first conveying roller 304 and the second conveying roller 306. The winding assembly 4 includes a winding roller 403 disposed in the rear mounting groove 102 of the mounting frame 101 via a connecting plate 401.

[0023] A first connecting block 202 is fixedly connected to the outer surface of the tension adjusting rod 201, and a connecting rod 203 is fixedly connected to the outer surface of the first connecting block 202. The top of the connecting rod 203 is rotatably connected to the inside of the second connecting block 204.

[0024] The second connecting block 204 is fixedly connected to the bottom of the outer surface of the connecting plate 205. The outer surface of the connecting plate 205 passes through the mounting bracket 101 and is fixedly connected to the limiting rod 206. The limiting rod 206 is rotatably connected to the inside of the mounting bracket 101.

[0025] When the limit rod 206 is rotated, it drives the connecting plate 205 to rotate. The outer surface of the second connecting block 204 at the bottom of its outer surface is fitted with a connecting rod 203, and the bottom of the connecting rod 203 is fitted outside the first connecting block 202. This can drive the tension adjusting rod 201 to slide within the connecting frame 103. By using the up and down sliding of the tension adjusting rod 201, the tension of the aluminum foil can be adjusted.

[0026] A servo motor 301 is fixedly connected to the outer surface of the mounting bracket 101. The drive rod at the output end of the servo motor 301 is connected to a transmission chain 302. The side of the transmission chain 302 away from the drive rod is connected to the outer surface of the third connecting block 303.

[0027] The outer surface of the third connecting block 303 is fixedly connected to the first conveying roller 304 through the mounting frame 101. The first conveying roller 304 is rotatably connected to the inside of the mounting frame 101, and the outer surface of the first conveying roller 304 is fixedly connected to the drive gear 305.

[0028] A force-bearing gear 307 is fixedly connected to the outer surface of the second conveying roller 306. The force-bearing gear 307 meshes with the drive gear 305. An embedded block 308 is fixedly connected to the inside of the mounting frame 101 by a fixing bolt 311. An installation rod 309 is fixedly connected to the outer surface of the embedded block 308. A blade 310 is fixedly connected to the outer surface of the installation rod 309.

[0029] Utilizing the meshing feature of the drive gear 305 and the force-bearing gear 307 on the outer surface of the first conveying roller 304, the second conveying roller 306 is driven to rotate in the opposite direction to the first conveying roller 304, thereby conveying the aluminum foil. The embedded block 308, which is fixedly connected by the fixing bolt 311, has its mounting rod 309 located on one side of the first conveying roller 304 and the second conveying roller 306. The blade 310 on the outer surface of the mounting rod 309 is used to cut the aluminum foil.

[0030] A connecting plate 401 is threadedly connected to the outer surface of the mounting frame 101. A winding motor 402 is fixedly connected to the outer surface of the connecting plate 401. A winding roller 403 is fixedly connected to the output end of the winding motor 402 through the connecting plate 401. The winding roller 403 is rotatably connected to the rear mounting groove 102 of the mounting frame 101. A collecting sleeve 404 is sleeved on the outer surface of the winding roller 403.

[0031] The implementation principle of the aluminum foil slitting device in this embodiment is as follows: After the unslit aluminum foil is placed on the surface of the feed roller 104, the feed roller 104 is inserted into the mounting groove 102. The free end of the aluminum foil passes through the bottom of the tension adjusting rod 201, through the surface of the limiting rod 206, and then through the space between the first conveying roller 304 and the second conveying roller 306, finally fitting onto the collecting sleeve 404 on the outer surface of the take-up roller 403. As the take-up motor 402, which is fixedly connected by the connecting plate 401, starts, it drives the take-up roller 403 to rotate, and the feed roller 10... 4. The aluminum foil on the outer surface is wound onto the outer surface of the collecting sleeve 404 by the tension adjusting rod 201, the limiting rod 206, the first conveying roller 304 and the second conveying roller 306. When the limiting rod 206 is rotated, it drives the connecting plate 205 to rotate. The outer surface of the second connecting block 204 at the bottom of its outer surface is fitted with a connecting rod 203, and the bottom of the connecting rod 203 is fitted outside the first connecting block 202. This can drive the tension adjusting rod 201 to slide within the connecting frame 103. By sliding the tension adjusting rod 201 up and down, the tension of the aluminum foil can be adjusted. Driven by the servo motor 301, the drive rod rotates, and the third connecting block 303 and the first conveying roller 304 rotate under the connection of the transmission chain 302. Utilizing the meshing of the drive gear 305 and the force-bearing gear 307 on the outer surface of the first conveying roller 304, the second conveying roller 306 rotates in the opposite direction to the first conveying roller 304, thereby conveying the aluminum foil. The embedded block 308, which is fixedly connected by the fixing bolt 311, has its mounting rod 309 located on one side of the first conveying roller 304 and the second conveying roller 306. The blade 310 on the outer surface of the mounting rod 309 cuts the aluminum foil. Finally, the collecting sleeve 404 on the outer surface of the winding roller 403 is used for winding. By removing the connecting plate 401 threaded to the outer surface of the mounting frame 101, the winding assembly 4 can be disassembled from the mounting assembly 1. Since the collecting sleeve 404 is fitted onto the surface of the winding roller 403, removing the collecting sleeve 404 allows for centralized processing of the cut aluminum foil.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
