[0036] See Figures 1-3, A cutting mechanism of a winding device, including a connecting frame 1, a support assembly, a pressing-down assembly, and a blade 2. Specifically, there are two connecting frames 1, which are respectively fixedly arranged on the frame 3 of the winding device and are respectively located at both ends of the frame 3. The two ends of the support assembly are respectively fixedly arranged on the two connecting frames 1, and there is a long strip-shaped through groove 4 in the middle of the support assembly. The length direction of the through groove 4 is the same as the length direction of the drum 10 on the winding device.

[0037] A pressing-down assembly is also arranged on the connecting frame 1. The pressing-down assembly is located above the support assembly. There is a pressing part on the pressing-down assembly that can fit on the top surface of the support assembly. The blade 2 is long strip-shaped and is arranged on the pressing-down assembly, and the cutting edge of the blade 2 faces the through groove 4 in the middle of the support assembly.

[0038] The pressing-down assembly and the support assembly are arranged on the connecting frame 1, and the blade 2 is arranged on the pressing-down assembly. When cutting, the aluminum foil is pressed by the pressing-down assembly and the support assembly, so that the cutting edge of the blade 2 can cut the aluminum foil from the through groove 4.

[0039] Since the pressing-down assembly and the support assembly press and straighten the aluminum foil, during the process of the blade 2 cutting the aluminum foil, the aluminum foil will not be bent, so it can ensure that the cut of the aluminum foil is in a straight state.

[0040] In one specific embodiment:

[0041] A bottom knife 11 with its cutting edge facing the blade 2 is arranged in the through groove 4 in the middle of the support assembly. A shearing structure can be formed between the bottom knife 11 and the blade 2. Thus, during the process of cutting the aluminum foil, it can be cut by a shearing method to ensure that there are no notches on the cut of the aluminum foil.

[0042] In another specific embodiment:

[0043] The support assembly includes a support plate 5, a support rod 6, a triangular block 7, and a motor 8. Among them, there are two support plates 5, which are arranged on the two connecting frames 1 in parallel. A chute 9 is respectively arranged on the two support plates 5. The length direction of the chute 9 is the same as the length direction of the support plate 5, and the length direction of the support plate 5 is perpendicular to the length direction of the drum 10 of the winding device.

[0044] The two ends of the support rod 6 are respectively slidably arranged in the chutes 9 on the two support plates 5. Two support rods 6 are arranged on the two support plates 5 in parallel. There is a gap between the two support rods 6, and this gap is the through groove 4 of the support assembly. The above-mentioned bottom knife 11 is arranged in the through groove 4.

[0045] The triangular block 7 is slidably arranged on the side of the connecting frame 1. The triangular block 7 is an isosceles triangle, and both sides of the triangular block 7 can slide and contact with two support rods 6 respectively. A threaded hole is provided at the bottom of the triangular block 7, and a screw rod 12 is matched in the threaded hole. The motor 8 is fixedly arranged on the connecting frame 1, and the output shaft of the motor 8 is coaxially connected to one end of the screw rod 12. The screw rod 12 can be directly driven by the motor 8 to rotate forward or backward.

[0046] Preferably, two sliding grooves 9 are provided on the top surface of the support plate 5. A spring is respectively arranged in each of the two sliding grooves 9. One end of the spring abuts against one end of the two sliding grooves 9 away from each other, and the other end of the spring abuts against the support rod 6.

[0047] In this embodiment, after the pressing part of the pressing component presses the aluminum foil against the support component, the triangular block 7 is driven by the motor 8 to move in the vertical direction, so that the two support rods 6 are driven to move away from each other through the inclined surfaces on both sides of the triangular block 7, and then the aluminum foil is straightened, and then it is convenient for the cutting knife and the bottom knife 11 to cooperate to cut the aluminum foil.

[0048] In another specific embodiment:

[0049] The pressing component includes a connecting plate 13, a pressing rod 14, a driving plate 15 and a cylinder 16. Specifically, there are two connecting plates 13, which are respectively connected to the connecting frame 1 through a cylinder 16, and the connecting plates 13 are arranged at the end of the piston rod of the cylinder 16. The two connecting plates 13 are respectively located above the two support plates 5, and the length direction of the connecting plates 13 is parallel to the length direction of the support plates 5.

[0050] Two connecting grooves are provided on the bottom surface of the connecting plate 13. The length direction of the connecting grooves is consistent with the length direction of the connecting plate 13. At the same time, the cross section of the connecting grooves is T-shaped, and the pressing rod 14 is matched with the connecting grooves.

[0051] Two pressing rods 14 are slidably arranged on the two connecting plates 13. The two ends of the pressing rod 14 are respectively slidably arranged in the connecting grooves on the two connecting plates 13. And the two pressing rods 14 are respectively located above the two support rods 6.

[0052] Springs are also arranged in the connecting grooves on the connecting plate 13. One end of the spring in the connecting groove abuts against one end of two adjacent connecting grooves on the same connecting plate 13 away from each other, and the other end abuts against the pressing rod 14.

[0053] In addition, a driving plate 15 is respectively arranged on one side of the two support rods 6 close to each other.

[0054] In this embodiment, the cylinder 16 drives the connecting plate 13 to descend, thereby driving the pressing rod 14 to fit with the supporting rod 6. Therefore, the pressing rod 14 is the pressing part of the downward pressing assembly. After the pressing rod 14 presses the aluminum foil against the supporting rod 6, the tops of the driving plates 15 at the ends of the two supporting rods 6 are inserted between the two pressing rods 14. Then, the motor 8 is started to drive the two supporting rods 6 to move away from each other. At this time, the two driving plates 15 drive the two pressing rods 14 to move away from each other, so that the aluminum foil is straightened through the synchronous movement of the pressing rod 14 and the supporting rod 6.

[0055] Preferably, a cross beam is provided between the two connecting plates 13. A cylinder 16 is also provided on the cross beam. The piston rod of the cylinder 16 on the cross beam is connected to the blade 2 and is used to drive you to descend to produce a shearing effect with the bottom knife 11.

[0058] By symmetrically arranging the motor 8, the screw rod 12, the triangular block 7 and the driving plate 15, the movements at both ends of the supporting rod 6 and the movements at both ends of the pressing rod 14 can be in a balanced state.

[0059] The above-described embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
