[0029] like Figure 1 As shown, the film feeding and receiving tray mechanism 1 includes a feeding shaft 45 and a receiving shaft 46. The feeding shaft 45 is rotatably connected to the material plate 47, and the receiving shaft 46 is rotatably connected to the material plate 47.

[0031] like Figure 2-5 As shown, the die-cutting mechanism 2 includes a die-cutting bracket 4, on which a die-cutting assembly 5 and a film feeding assembly 6 are fixedly connected. The die-cutting bracket 4 has a material inlet 7 that cooperates with the die-cutting assembly 5, and a feeding channel 8 and a discharging channel 9 that cooperate with the film feeding assembly 6. The film feeding assembly 6 clamps the already-cut aluminum film and moves it a preset distance. The aluminum film below the material inlet 7 becomes an uncut aluminum film again. The die-cutting assembly 5 cuts the aluminum film, producing a film sheet, which awaits pickup by the film feeding mechanism 3.
[0032] Specifically, the die support 4 includes a die fixing base plate 38, with die support plates 39 fixed on both sides of the die fixing base plate 38. The die plate 10 is fixed on the die support plates 39. A dust suction baffle 40 is fixedly connected to one side of the die support plate 39, and the dust suction baffle 40 has a notch 41 for aluminum film to pass through. A sealing baffle 42 is fixedly connected to the other side of the die support plate 39, and the sealing baffle 42 has a notch 43 for aluminum film to pass through.

[0038] The elastic guide post assembly 14 includes a pressure plate guide post 28 and a spring 29. The spring 29 is sleeved on the pressure plate guide post 28. The upper end of the pressure plate guide post 28 is fixedly connected to the pressure plate 11, and the lower end of the pressure plate guide post 28 is slidably connected to the die fixing plate 15. One end of the spring 29 abuts against the pressure plate 11, and the other end of the spring 29 abuts against the die fixing plate 15.
[0039] During the punching process, drive mechanism 217 first drives the pusher plate 20 to move upward, pressing the aluminum film. Drive mechanism 16 then drives the die fixing plate 15 to move upward, and the pressure plate 11 first presses against the punching die 10, pressing the aluminum film. The spring 29 in the elastic guide post assembly 14 is compressed, and the toothed cutter 23 moves upward relative to the pressure plate 11, thereby slicing the aluminum film into a sheet. During this process, the pusher plate 20 presses down on the middle, and the pressure plate 11 presses down on the periphery, so that the aluminum film maintains a certain tension, which facilitates the toothed cutter 23 to smoothly cut out the sheet.
[0040] After the diaphragm is cut off, the first drive mechanism 16 drives the die fixing plate 15 to move down, the toothed cutter 23 moves down relative to the pressure plate 11, the spring 29 in the elastic guide post assembly 14 returns to its original state, the pressure plate 11 moves down, the second drive mechanism 17 drives the pusher plate 20 to move down, and the die assembly 5 returns to its original state.

[0042] The aluminum film passes between the conveyor shaft 30 and the pressure roller 31. The drive mechanism 34 drives the pressure roller shaft 33 to move towards the conveyor shaft 30, causing the pressure roller 31 to press the aluminum film. When the rotary drive motor 61 drives the conveyor shaft 30 to rotate, it moves the aluminum film downwards a preset distance. Each time a film sheet is punched out, the film feeding assembly 6 moves the aluminum film once.

A second spring 36 is sleeved on the film feeding guide post 35. The pressure roller support plate 59 has a guide surface 37, which is in contact with the film feeding bracket 32. The guide surface 37 and the film feeding guide post 35 guide the movement of the pressure roller 31 to prevent the pressure roller 31 from deflecting and causing insufficient pressure. The second spring 36 has a certain preload on the pressure roller 31 to prevent insufficient pressure and also has a certain buffering effect.
