DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figures 1-3As shown in the figure, the present utility model provides a technical solution: a cutting device for carbon foil production, including a workbench 1. A support rod 3 is fixed on the top of the workbench 1, a top plate 4 is fixed on the top of the support rod 3, a cylinder 5 is fixed on the top of the top plate 4, a cutting knife 6 is fixed on the bottom of the cylinder 5, and a cutting groove 2 is formed on the workbench 1. Thus, when the carbon foil is placed on the workbench 1, by starting the cylinder 5, the cutting knife 6 moves downward. Then, through the cooperation of the cutting knife 6 and the cutting groove 2, the carbon foil can be cut. A sliding groove 7 is formed on the front of the workbench 1, and a flattening mechanism 8 is arranged on the inner wall of the sliding groove 7.

[0022] The above-mentioned flattening mechanism 8 includes a slider 801, a moving frame 802, a connecting block 804, a connecting block 803, a movable rod 805, a connecting seat 806, a rotating rod 807, a flattening roller 808, a threaded rod 809 and a rotary knob 810. The slider 801 is slidably installed on the inner wall of the sliding groove 7. There are two groups of sliders 801, and the two groups of sliders 801 are symmetrically arranged with the center line of the workbench 1 in the vertical direction as the axis of symmetry. A moving frame 802 is fixed on the side wall of the slider 801. A connecting block 803 is fixed on the top of the moving frame 802. A connecting block 804 is fixed on the side wall of the cutting knife 6. One side of the connecting block 804 away from the cutting knife 6 is hinged with a movable rod 805. One end of the movable rod 805 away from the cutting knife 6 is hinged on the connecting block 803. A connecting seat 806 is slidably installed inside the moving frame 802. A rotating rod 807 is rotatably installed inside the connecting seat 806. A flattening roller 808 is fixed on the outer wall of the rotating rod 807. There are two groups of flattening rollers 808, and the two groups of flattening rollers 808 are symmetrically arranged with the center line of the workbench 1 in the vertical direction as the axis of symmetry. Thus, when the cylinder 5 drives the cutting knife 6 to move downward for cutting, the connecting block 804 can be moved downward. Through the movable rod 805, the movable rod 805 squeezes the connecting block 803 away from the support rod 3, so that the moving frame 802 moves. Then, the two groups of flattening rollers 808 can be moved away from each other, and the flattening rollers 808 roll on the surface of the carbon foil. Then, it can flatten the carbon foil on the workbench 1. And the two groups of flattening rollers 808 are attached to the carbon foil and move away from each other. Then, the carbon foil can be in a straightened state. Then, it is convenient for the cutting knife 6 to perform cutting operations. A threaded rod 809 penetrates through the top of the moving frame 802. The penetration part of the threaded rod 809 and the moving frame 802 is in threaded connection. The bottom of the threaded rod 809 is rotatably installed on the top of the connecting seat 806. A rotary knob 810 is fixed on the top of the threaded rod 809. By rotating the rotary knob 810, the threaded rod 809 can be rotated, and the threaded rod 809 can drive the connecting seat 806 to move up and down. Then, the height of the flattening roller 808 can be adjusted. Then, it can flatten carbon foils with different thicknesses. When the cylinder 5 is started and the cutting knife 6 moves upward, through the connecting block 804 and the movable rod 805, the connecting block 803 drives the two groups of moving frames 802 to approach each other. Then, the two groups of flattening rollers 808 approach each other for the next flattening operation.

[0023] Working principle: When it is necessary to cut the carbon foil, place the carbon foil on the workbench 1. By starting the cylinder 5, the cutting knife 6 moves downward. Then, through the cooperation of the cutting knife 6 and the cutting groove 2, the carbon foil can be cut. When the cylinder 5 drives the cutting knife 6 to cut downward, the connecting block 804 can be moved downward. Through the movable rod 805, the movable rod 805 squeezes the connecting block 803 away from the support rod 3, causing the moving frame 802 to move. Then, the two flattening rollers 808 can move away from each other, and the flattening rollers 808 roll on the surface of the carbon foil, which can flatten the carbon foil on the workbench 1. Moreover, the two flattening rollers 808 move away while fitting the carbon foil, so that the carbon foil can be in a straightened state, which is convenient for the cutting knife 6 to perform the cutting operation. By rotating the knob 810, the threaded rod 809 can be rotated, and the threaded rod 809 can drive the connecting seat 806 to move up and down, so as to adjust the height of the flattening roller 808, and then flatten the carbon foil with different thicknesses.

[0024] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
