The top of the bottom plate 1 is connected to the waste trough 13, and is located below the anvil 10.

[0038] In this embodiment, it should be further explained that the limiting post 603 prevents the slider 604 from moving in the vertical direction, the limiting block 609 prevents the pressing block 608 from sliding out of the limiting base 601, and the rotating arc block 612 and the fixed arc groove 613 prevent the limiting groove block 602 from separating from the top of the limiting base 601 when the tool holder roller shaft 4 rotates.

[0039] When the cutting blade 702 needs to be replaced, the pressing block 608 is pressed upward, so that the pressing block 608 and the transmission column 610 move upward, pushing the locking bevel 605 to slide and disengaging the locking bevel 605 from the locking groove 607, driving the slider 604 to slide, and the first spring 606 is compressed by the pressure. At the same time, the knife holder roller shaft 4 is rotated to make the rotating plate 5 vertical, so that the rotating arc block 612 releases the fixed lock on the limit slot block 602, and the limit slot block 602 is removed. The first spring 6 06 rebounds and resets, driving the slider 604 and the locking bevel 605 to reset, which is convenient for re-fixing the limit groove block 602. The tool holder roller shaft 4 is removed, and the pull button 704 is pulled. The second spring 705 is stretched by the tension, driving the tool holder fixing column 703 to slide out of the fixing groove 706. At this time, the sliding tool holder ring 701 is removed from the tool holder roller shaft 4. The pull button is released, and the second spring 705 rebounds and resets, driving the tool holder fixing column 703 to reset, which is convenient for re-installing the tool holder ring 701.

[0040] After that, the knife holder ring 701 that needs to be replaced is sleeved on the outside of the knife holder roller shaft 4, and the pull button 704 is pulled. The second spring 705 is stretched under the tension, driving the knife holder fixing column 703 to slide, so that the knife holder ring 701 can slide on the outside of the knife holder roller shaft 4, and the knife holder ring 701 is moved to the corresponding position. The pull button is released, and the second spring 705 rebounds and resets, driving the knife holder fixing column 703 to reset and slide into the fixing groove 706, and the knife holder ring 701 is fixed and locked. After the installation of the cutting blade 702 is completed, the knife holder roller shaft 4 is placed on the top of the limit base 601, and the rotating plate 5 is slid into the inside of the knife holder roller shaft 4. Then, The limiting groove block 602 is placed on the top of the limiting base 601. At this time, the top of the limiting base 601 contacts the inclined surface of the locking bevel 605 and pushes the locking bevel 605 to slide. The first spring 606 is compressed by the pressure and continues to move the limiting groove block 602 downward. When the bottom end of the limiting groove block 602 is in contact with the top of the limiting base 601, the first spring 606 rebounds and resets, driving the slider 604 and the locking bevel 605 to reset and slide the locking bevel 605 into the locking groove 607, so that the locking bevel 605 fixes and locks the limiting groove block 602. At this time, the replacement of the cutting blade 702 is completed.

[0041] When it is necessary to cut the capacitor film, the capacitor film to be cut is sleeved on the outside of the feeding roller 8, and the capacitor film is passed in turn between the pressing rollers 9, above the anvil 10 and outside the winding roller 11. At this time, all motors 12 are turned on to rotate the runner 3, the feeding roller 8, the pressing roller 9, the anvil 10 and the winding roller 11, so that the capacitor film is automatically pressed flat between the pressing rollers 9, above the anvil 10 and driven by the rotating runner 3 to rotate for cutting. Finally, the rolling roller 11 rolls to collect the cut capacitor film, and the cut waste automatically falls into the waste trough 13 to complete the cutting of the capacitor film.

[0042] Please refer to Figure 1 The side baffles 2 and the rotating wheels 3 are symmetrically arranged in two groups, which are convenient for fixing the tool holder roller 4, the limit assembly 6, the feeding roller 8, the pressing roller 9, the anvil 10 and the winding roller 11.

[0043] In this embodiment, the knife holder roller 4 can be limited by the limiting assembly 6, and the feeding roller 8, the pressing roller 9, the anvil 10 and the winding roller 11 will not tilt during rotation to affect the cutting of the capacitor film.

[0044] Please refer to Figure 1The limiting components 6 are symmetrically arranged in two groups, and each group of limiting components 6 has two symmetrically arranged limiting columns 603, sliders 604, locking bevel blocks 605, first springs 606, locking grooves 607, pressing blocks 608, limiting blocks 609, and transmission columns 610. There are multiple first springs 606 evenly distributed between the other end of the inner side of the limiting groove block 602 and the other end of the slider 604, and two rotating arc blocks 612 are symmetrically arranged inside the limiting base 601 and the limiting groove block 602, so that the limiting of the tool holder roller shaft 4 is more stable.

[0045] In this embodiment, the symmetrically arranged limit assembly 6 allows both ends of the tool holder roller shaft 4 to be limited by the limit assembly 6, and the tool holder roller shaft 4 will not tilt. Each set of limit assemblies 6 symmetrically arranged two sets of limit columns 603, sliders 604, locking bevels 605, first springs 606, locking grooves 607, pressing blocks 608, limit blocks 609, and transmission columns 610 prevent the limit slot block 602 from shaking and affecting the rotation of the tool holder roller shaft 4. Multiple evenly distributed first springs The spring 606 prevents the sliding of the slider 604 from tilting, so that the locking bevel block 605 can slide in and out of the locking groove 607. The two rotating arc blocks 612 symmetrically arranged inside the limit base 601 and the limit groove block 602 enable the tool holder roller shaft 4 to rotate. The rotating plate 5 rotates to drive the rotating arc blocks 612 inside the limit base 601 and the limit groove block 602 to rotate into the limit groove block 602 and the limit base 601 respectively, thereby fixing and locking the limit groove block 602.

[0046] Please refer to Figure 4 There are multiple knife holder rings 701, cutting blades 702, knife holder fixing columns 703, pull buttons 704, and second springs 705, and there are multiple fixing grooves 706 evenly distributed on the outside of the knife holder roller shaft 4.

[0047] In this embodiment: multiple tool holder rings 701, cutting blades 702, tool holder fixing columns 703, pull buttons 704, and second springs 705 enable the capacitor film cutting device to cut a whole piece of capacitor film into multiple capacitor film strips, and multiple evenly distributed fixing grooves 706 allow the positions of the multiple tool holder rings 701 to be adjusted and fixed.

[0048] Please refer to Figure 1 There are multiple motors 12 at the other end of the side baffle 2, and the output end passes through one end of the side baffle 2 and is respectively connected to the runner 3, the feeding roller 8, the pressing roller 9, the anvil 10 and the winding roller 11. There are two pressing rollers 9 symmetrically arranged, and the side surfaces of the two pressing rollers 9 are in contact with each other.

[0049] In this embodiment: multiple motors 12 enable the rotating wheel 3, the feeding roller 8, the pressing roller 9, the anvil 10 and the winding roller 11 to rotate simultaneously; the pressing roller 9 with two sides in contact with each other enables the capacitor film to be pressed flat, thereby avoiding wrinkles in the capacitor film before cutting that affect the cutting.
