[0031] Example
[0032] To address the issues of low efficiency and inability to guarantee consistency between individual copper foils in existing copper foil single-sheet cutting machines, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses a double-roll copper foil cutting and stacking device, including a double-roll sending mechanism 10, a cutting mechanism 20, a stacking conveying mechanism 30, and a material pulling mechanism 40;
[0033] The dual-roll feeding mechanism 10 includes a material rack 11, an upper feeding assembly 12, and a lower feeding assembly 13. The upper feeding assembly 12 and the lower feeding assembly 13 are respectively located on the upper and lower sides of the material rack 11. The material rack 11 is equipped with four guide assemblies 14 for guiding the upper feeding assembly 12 and the lower feeding assembly 13 respectively. The four guide assemblies 14 are arranged in pairs. In specific implementation, the copper foil sent by the upper feeding assembly 12 and the lower feeding assembly 13 will be guided by two guide assemblies 14 respectively and then stacked together.
[0034] The cutting mechanism 20 includes a cutting frame 21, a feeding traction component 22, and a cutting component 23. The cutting frame 21 is located on the left side of the material rack 11, the feeding traction component 22 is located on the right side of the cutting frame 21, and the cutting component 23 is located on the left side of the cutting frame 21. In specific implementation, the feeding traction component 22 pulls the copper foil sent by the upper feeding component 12 and the lower feeding component 13 to the bottom of the cutting component 23 and out from the left side of the cutting component 23.
[0035] The stacking conveyor mechanism 30 includes a base frame 31, a lifting drive assembly 32, and a conveyor 33. The base frame 31 is located on the left side of the cutting frame 21, the lifting drive assembly 32 is located above the base frame 31, and the conveyor 33 is connected above the lifting drive assembly 32. Before the double-roll copper foil cutting and stacking equipment is implemented, the operator first places an empty pallet on the conveyor 33. Each time the copper foil is stacked, the lifting drive assembly 32 will drive the conveyor 33 to descend to a set height. When the copper foil on the conveyor 33 is stacked to the set height, the conveyor 33 will send out the pallet on the conveyor 33 (the operator can set up a handcart outside the base frame 31 in advance to receive the pallet).
[0036] The material pulling mechanism 40 includes a transverse drive assembly 41, a linear guide rail 42, and a clamping assembly 43. The transverse drive assembly 41 and the linear guide rail 42 are located above the front and rear sides of the conveyor 33. The clamping assembly 43 is connected to the transverse drive assembly 41 and the linear guide rail 42 facing the cutting frame 21. When the cutting assembly 23 cuts the copper foil, the transverse drive assembly 41 and the linear guide rail 42 will cooperate to drive the clamping assembly 43 to move to the right to clamp the exposed copper foil at the cutting assembly 23. Then, the transverse drive assembly 41 and the linear guide rail 42 will cooperate to drive the clamping assembly 43 to move to the left to pull the copper foil out to the set length. After that, the cutting assembly 23 can perform the cutting operation. After the cutting assembly 23 has finished cutting the copper foil, the transverse drive assembly 41 and the linear guide rail 42 will continue to drive the clamping assembly 43 to move to the right so that the cut copper foil is stacked on the pallet.
[0037] To prevent external dust from falling into the double-roll copper foil cutting and stacking equipment, this application also includes a dust cover 50 for covering the entire equipment, preventing dust from entering and avoiding unnecessary contamination of the copper foil.
[0038] In a preferred embodiment, the lowering component 13 of this application is connected to the material rack 11 via a hand-cranked horizontal module 15 (the specific structure of which is known technology and will not be described in detail here).

The two hand-cranked lifting modules 141 are arranged one in front of the other on the material rack 11. The guide wheel 142 is connected between the two hand-cranked lifting modules 141. During the specific installation process, the operator can manually adjust the hand-cranked lifting modules 141 to make fine adjustments to the height of the guide wheel 142, thereby achieving precise guidance of the copper foil.
[0041] In one specific implementation, the feeding and traction assembly 22 of this application includes a first cylinder 221, a pressure roller 223, a feeding motor 224, and a guide wheel 225. The first cylinder 221 is located above the cutting frame 21. The pressure roller 223 is connected to the piston rod of the first cylinder 221 via a wheel frame 222. The feeding motor 224 is located below the cutting frame 21. The guide wheel 225 is located below the pressure roller 223 on the cutting frame 21 and is connected to the feeding motor 224 for transmission. In a specific implementation, the first cylinder 221 drives the wheel frame 222 to descend, causing the pressure roller 223 to cooperate with the guide wheel 225. When the feeding motor 224 drives the guide wheel 225 to rotate, the guide wheel 225 and the pressure roller 223 will squeeze and feed the copper foil out.
[0042] In one specific implementation, the cutting component 23 of this application is a guillotine cutting machine with a lifting upper blade 231 and a fixed lower blade 232. The specific structure of the guillotine cutting machine is known technology. In the specific implementation process, when the lifting upper blade 231 is controlled to descend, it can cooperate with the fixed lower blade 232 to cut the double-layer copper foil.
[0043] In a preferred embodiment, the lateral drive component 41 of this application is a servo screw module. In specific implementation, if other types of lateral drive components 41 can achieve the corresponding functions, this technical field can adapt and adopt them.

When clamping copper foil, the clamping spade 432 will be located below the copper foil, while the clamping plates 434 will be located above the copper foil. When the second cylinders 433 drive the clamping plates 434 to descend, they can cooperate with the clamping spade 432 to clamp the copper foil.
[0045] In a preferred embodiment, the lifting drive assembly 32 of this application is a worm gear screw jack (this structure is known technology, and the specific principle will not be described in detail), and the conveyor 33 is located on the lifting platform of the worm gear screw jack. Under the drive of the worm gear screw jack, the conveyor 33 can realize lifting movement.
[0046] In addition to the above structure, to prevent the stacked copper foil from being carried away by the feeding mechanism 40 during operation, this application also provides a flipping pressing mechanism 60 between the stacking mechanism and the cutting mechanism 20. The pressing mechanism includes a pressing arm 61, which has several U-shaped notches 611 on the side facing the stacking conveying mechanism 30. Each of the U-shaped notches 611 has an outwardly extending flipping pressing block 63 hinged to its upper part. The bottom of the flipping pressing block 63 is provided with a hinge block 631. The several U-shaped notches... Each groove 611 has a third cylinder 62 hinged to its lower interior. The piston rod of the third cylinder 62 is hinged to the hinge block 631. In the specific implementation process, if the pulling mechanism 40 pulls the cut copper foil to stack or the belt conveyor needs to transport and unload the pallet, several third cylinders 62 will drive several flipping clamps to rotate 90° to stop and clamp the stacked copper foil. In other states, several third cylinders 62 will drive several flipping clamps to rotate and press the stacked copper foil.
