[0023] As Figures 1 to 4 shown, a double-line strip die-cutting machine includes a workbench 1. A support plate 2 is fixedly connected to the top of the workbench 1. Two sets of roller driving mechanisms 3 are arranged between the two sides inside the support plate 2. The roller driving mechanism 3 is composed of a driving wheel 4 and a driven wheel 5. The number of the driven wheels 5 is two and they are respectively meshed with the outer wall of the driving wheel 4. The driving wheel 4 and the two driven wheels 5 are all rotatably connected to the outer wall of the support plate 2. A first servo motor 8 is fixedly connected to the side wall of the support plate 2. The shaft portion of the first servo motor 8 penetrates through the inner wall of the support plate 2 and is fixedly connected to the side wall of the driving wheel 4. A driving roller 6 and a driven roller 7 are rotatably connected inside the support plate 2. The number of the driven rollers 7 is two and they are respectively rotatably connected between the inner walls of the support plate 2. The shaft portion of the driving roller 6 penetrates through the outer wall of the support plate 2 and is fixedly connected to the side wall of the driving wheel 4. The shaft portion of the driven roller 7 penetrates through the outer wall of the support plate 2 and is fixedly connected to the side wall of the driven wheel 5. The driving wheel 4, the driven wheels 5, the driving roller 6 and the driven roller 7 are all arranged on the same vertical line;

[0024] First, place two bundles of strip materials on the first material feeding wheel 20 and the second material feeding wheel 21. Then, pass one end of the two bundles of strip materials through the outer wall of the guide wheel 19 and the top and bottom of the driving roller 6. Then, start the first servo motor 8 through an external power source. The first servo motor 8 drives the driving wheel 4 to rotate. The driving wheel 4 drives the driven wheels 5 at the top and bottom to rotate. Then, the driving wheel 4 and the driven wheels 5 drive the driving roller 6 and the driven roller 7 to rotate, thereby preventing the strip material from wrinkling and being able to drive two strip materials at the same time.

[0025] Further, referring to the attachedFigure 2 and Figure 3 As shown in Figure 3 , a cutting drive mechanism 9 is arranged at the middle position between the inner walls of the support plate 2 and between two sets of roller drive mechanisms 3. The cutting drive mechanism 9 includes a first gear 10, a second gear 11 and a third gear 12. The first gear 10, the second gear 11 and the third gear 12 are all rotatably connected to the inner wall of the support plate 2. The outer wall of the first gear 10 meshes with the outer wall of the second gear 11, and the outer wall of the second gear 11 meshes with the outer wall of the third gear 12. The side walls of the first gear 10 and the third gear 12 are both fixedly connected with an incomplete gear 13 through a connecting shaft. The outer wall of the support plate 2 is fixedly connected with a second servo motor 22. The first gear 10 passes through the outer wall of the support plate 2 through a connecting shaft and is fixedly connected to the output end of the second servo motor 22. A reciprocating rod 14 is arranged at the middle part between the first gear 10 and the third gear 12. Tooth grooves 15 are arranged on both side walls of the reciprocating rod 14.

One side of the cutting knife 17 is mutually attached to one side of the cutting template 18;

[0026] When the cutting drive mechanism 9 is in use, the second servo motor 22 is started through an external power source. The second servo motor 22 drives the incomplete gear 13 and the first gear 10 to rotate. When the first gear 10 rotates, it will drive the tooth groove 15 to rotate synchronously. Subsequently, the tooth groove 15 drives the third gear 12 and the second gear 11 to rotate synchronously. Then, through the mutual cooperation of the incomplete gears 13 on the side walls of the first gear 10 and the third gear 12 and meshing through the tooth groove 15, the reciprocating rod 14 is driven to move up and down reciprocally. When the reciprocating rod 14 moves up and down reciprocally, it will drive the cutting knife 17 to move and mutually attach to the top and bottom strip materials for cutting, so as to process two strip materials, thereby doubling the production efficiency, improving the production benefit, reducing the equipment cost and maintenance cost at the same time, and avoiding the waste of production space and the increase of management difficulty.
