The upper end of the horizontal plate 34 is fixed with a servo motor 35 through screws. The rear ends of the two mounting rods 32 pass through the mounting seat 31 and are connected by a conveyor belt 36 to rotate. The output end and the upper end mounting rod 32 are connected by screws. The two mounting rods 32 are provided with a pressure rod 37 at one end close to each other. The outer wall of the pressure rod 37 is fixed with a pressure wheel 38 by screws, and both sides of the pressure rod 37 are fixedly connected There is a mounting block 39. Two mounting seats 31 are provided with a mounting groove 310 on the side close to each other. The mounting blocks 39 are slidably connected in the mounting groove 310, and the mounting block 39 and the bottom surface of the mounting groove 310 are fixedly connected with extrusion The spring 311, the pay-off roller 2 and the winding mechanism 3 are provided with a mounting seat two 4 on the side close to the center of the base 1, and the upper end of the mounting seat 2 4 is rotatably mounted with a leveling roller 5, and the center of the base 1 is also provided with a slitting mechanism 6. The slitting mechanism 6 includes a mounting seat three 61. The upper ends of the two mounting seats three 61 are rotatably connected with a cutting rod 62 through a rolling bearing. The rear side wall of the rear mounting seat three 61 is also welded with a horizontal plate two 63 and a horizontal plate two The upper end of 63 is fixed with servo motor two 64 by screws. The rear side of cutting rod 62 passes through mounting seat three 61 and is fixedly connected with the output end of servo motor two 64 by screws. The outer wall of the cutting rod 62 is also provided with a sliding groove 65. The outer wall of the cutting rod 62 is also slidably connected with a cutting blade 66, and the inner wall of the cutting blade 66 is also fixedly connected with a sliding block 67. The sliding blocks 67 are slidably connected in the sliding groove 65 between two adjacent cutting blades 66 Each is provided with a balance spring 68, and the balance spring 68 is sleeved on the outer position of the cutting rod 62. The outer walls of both sides of the cutting rod 62 are fixed with a mounting plate 69. The upper and lower ends of the mounting plate 69 are fixed on the side facing away from the mounting seat 61 An electric telescopic rod 610 is connected, and the output end of the electric telescopic rod 610 is fixedly connected with a pressure plate 611 by screws.

[0029] In this embodiment, the pressure plate 611 is moved by pressing the electric telescopic rod 610 to realize the adjustment of the position of the cutting blade 66. At this time, under the action of the balance spring 68, the distance between two adjacent cutting blades 66 remains the same. The speed is fast, and it is convenient to slit the capacitor film of different specifications, and the slitting efficiency of the film is well guaranteed.

[0030] The winding mechanism 3 adopts staggered winding up and down to avoid the occurrence of friction and wear between two adjacent capacitor films. In the winding mechanism, the pressure roller 38 is always in contact with the winding under the action of the compression spring 311. The surface of the winding plate 33 is adhered, thereby ensuring the quality of the capacitor film winding.

[0031] Example two

[0032] Such as figure 1 As shown, this embodiment is basically the same as Embodiment 1. Preferably, both sides of the slitting mechanism 6 are provided with a pressing roller 7 and a pressing roller 2 8, and the pressing roller 2 8 is located away from the slitting mechanism 6. On one side, the height of the second pressure roller 8 is lower than the height of the first pressure roller 7.

[0033] In this embodiment, a pressing roller 7 and a pressing roller 8 are arranged on both sides of the slitting mechanism 6, and the height of the pressing roller 2 8 is lower than the height of the pressing roller 7 so that the capacitor The two sides of the film are pressed tightly to ensure more stable cutting of the capacitor film, thereby ensuring the cutting quality of the capacitor film.

[0034] Example three

[0035] Such as figure 1 with 2 As shown, this embodiment is basically the same as Embodiment 1. Preferably, two mounting seats 31 are provided and are symmetrically distributed at the front and rear positions of the base 1, and the mounting seats 31 are all welded on the upper end surface of the base 1, and the mounting rod 32 is provided with two and symmetrically distributed at the upper and lower ends of the mounting seat 31.

[0036] There are multiple winding reels 33, and the winding reels 33 on the two mounting rods 32 are staggered, and the pressing wheels 38 are both provided with multiple winding reels 33 and located on the side of the winding reels 33 near the center of the mounting seat 31, and press The outer wall of the wheel 38 is attached to the outer wall of the winding disk 33, the upper and lower ends of the horizontal plate 34 are also provided with through holes, and the conveyor belt 36 is placed in the through holes. The compression springs 311 are all located on the side close to the center of the mounting seat 31.

[0037] In this embodiment, multiple winding reels 33 are provided to realize simultaneous winding of multiple capacitor films after cutting, which can ensure the winding quality of the capacitor films.
