Combined with the power transmission chain of the second driven roller, the second drive rod, the second transmission chain, and the second driven rod, the second rotating rod and the slitting blade are driven to rotate at high speed, achieving continuous longitudinal cutting. The burr rate at the cut is lower than the industry standard, significantly improving the finished product qualification rate.

[0018] This utility model operates through a two-way unlocking structure composed of a mounting plate and a limiting plate, which enables the cutting components to be pulled out with zero gap and the independent modules to be separated. Operators can remove the cutting blades in the mounting base for re-sharpening or replacement. The design of rotating the adjusting screw to drive the clamping block to move horizontally removes the rigid constraint of the fixed base on the second rotating rod, realizing the overall removal of the cutting unit. This layered maintenance channel design shortens the replacement time of key components and eliminates the need to disassemble the entire machine, greatly reducing the downtime maintenance cost of the equipment.

Detailed Implementation

[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 1-6 This embodiment of a high-efficiency aluminum foil cutting device includes a mounting assembly 1, which includes a mounting frame 101. A servo motor 102 is fixedly connected to the outer surface of the mounting frame 101. The output end of the servo motor 102 passes through the mounting frame 101 and is fixedly connected to a drive roller 103. A drive roller 104, a second driven roller 105, and a third driven roller 106 are rotatably connected to the inside of the mounting frame 101 on one side of the drive roller 103. A conveyor belt 107 is sleeved on the outer surface of the drive roller 103, the first driven roller 104, the second driven roller 105, and the third driven roller 106. The device also includes: The reciprocating assembly 2 includes a connecting frame 202 fixedly connected to the center of the outer surface of the mounting frame 101. A first rotating rod 206 is rotatably connected inside the connecting frame 202. A limit rod 208 is fixedly connected to the outer surface of the first rotating rod 206 through a connecting plate 207. A guide rail 209 is fixedly connected to the inner wall of the connecting frame 202. The cutting assembly 3 includes a mounting base 303 that is slidably mounted on the outer surface of the limiting rod 208. Inside the mounting base 303, a cutting blade 304 is fixedly connected to the limiting plate 306 via a mounting plate 305. The slitting assembly 4 includes a fixed base 401 fixedly connected to the bottom of the connecting frame 202. The interior of the fixed base 401 is rotatably connected to a second rotating rod 404 via a clamping block 403.

[0023] The outer surface of the second driven roller 105 is fixedly connected to the first drive rod 203 through the mounting frame 101. The outer surface of the first drive rod 203 is connected to the first drive chain 204. The top of the first drive chain 204 is connected to the first driven rod 205. The first driven rod 205 is fixedly connected to the outer surface of the first rotating rod 206.

[0024] A connecting plate 207 is fixedly connected to the outer surface of the first rotating rod 206. A limiting rod 208 is fixedly connected to the outer surface of the connecting plate 207. A limiting frame 301 is slidably installed on the outer surface of the limiting rod 208. A guide groove 302 is provided inside the limiting frame 301. The guide groove 302 matches the limiting rod 208.

[0025] The bottom of the limiting bracket 301 is fixedly connected to the mounting base 303. A cutting blade 304 is inserted into the inside of the mounting base 303. A mounting plate 305 is inserted into the front end of the mounting base 303. A limiting plate 306 is inserted into the rear end of the mounting base 303. The mounting plate 305 and the limiting plate 306 are matched. The mounting base 303 is slidably installed inside the guide rail 209.

[0026] Since the limiting rod 208 is slidably installed in the guide groove 302 opened in the limiting frame 301, it can drive the limiting frame 301 to slide up and down. Since the mounting base 303 is slidably installed in the guide rail 209, with the continuous movement of the first driven roller 104, the mounting base 303 can be ensured to reciprocate.

[0027] An adjusting screw 402 is rotatably connected inside the connecting frame 202. A clamping block 403 is threadedly connected to the outer surface of the adjusting screw 402. The clamping block 403 is inserted into the interior of the fixed base 401.

[0028] The clamping block 403 is rotatably connected to the inside of the fixed base 401 by a second rotating rod 404. A slitting blade 405 is fixedly connected to the outer surface of the second rotating rod 404, and a second driven rod 408 is fixedly connected to one side of the outer surface of the second rotating rod 404.

[0029] The outer surface of the second driven rod 408 is connected to a second transmission chain 407, and the top of the second transmission chain 407 is connected to a second drive rod 406. The second drive rod 406 is fixedly connected to the outer surface of the first driven roller 104.

[0030] Since the second drive rod 406 and the second driven rod 408 are connected by the second transmission chain 407, the rotation of the second drive rod 406 can ensure that the second driven rod 408 rotates, thereby allowing the second rotating rod 404 to rotate under the limitation of the fixed seat 401 and the clamping block 403, and using the cutting blade 405 on its surface to cut the aluminum foil.

[0031] The implementation principle of the high-efficiency aluminum foil cutting device in this application embodiment is as follows: The aluminum foil to be cut is placed on the surface of the conveyor belt 107. Driven by the servo motor 102, the drive roller 103 rotates. Under the action of the conveyor belt 107, the first driven roller 104, the second driven roller 105, and the third driven roller 106 rotate within the mounting frame 101. The aluminum foil is conveyed to the slitting assembly 4 by the conveyor belt 107. As the second driven roller 105 rotates... The second drive rod 406 is driven to rotate. Since the second drive rod 406 and the second driven rod 408 are connected by the second transmission chain 407, the rotation of the second drive rod 406 ensures that the second driven rod 408 rotates. This causes the second rotating rod 404 to rotate under the limitation of the fixed seat 401 and the clamping block 403. The cutting blade 405 on its surface is used to cut the aluminum foil. The cut aluminum foil is then conveyed to the cutting assembly 3 by the conveyor belt 107. As the first driven roller 104 rotates, it drives the first drive rod 203 to rotate. Simultaneously, under the connection of the first transmission chain 204, it drives the first driven rod 205 to rotate within the connecting frame 202. When the first driven rod 205 is rotated, it drives the first rotating rod 206 to rotate. Since the limiting rod 208 is slidably installed in the guide groove 302 opened in the limiting frame 301, it can drive the limiting frame 301 to slide up and down. Since the mounting seat 303 is slidably installed in the guide rail 209, with the continuous movement of the first driven roller 104, it can ensure that the mounting seat 303 can reciprocate and slide, thereby cutting the slit aluminum foil paper. By removing the mounting plate 305 and the limiting plate 306 from the front and rear ends of the mounting base 303 respectively, the cutting blade 304 can be pulled out of the mounting base 303, facilitating maintenance or replacement of the cutting blade 304. As the adjusting screw 402 is rotated, the clamping block 403 slides horizontally, thereby removing the limitation of the clamping block 403 and the fixed base 401 on the second rotating rod 404, ensuring that the second rotating rod 404 can be removed separately, and ensuring maintenance and replacement of the cutting blade 405.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. 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.
