[0002] Capacitor film, also known as film capacitor or plastic film capacitor, is an important type of capacitor. It uses plastic film as dielectric and metal foil as electrode, which is overlapped with plastic film and wound into a cylindrical structure. According to the type of plastic film, capacitor film can be divided into polyethylene capacitor (also known as Mylar capacitor), polypropylene capacitor (also known as PP capacitor), polystyrene capacitor (also known as PS capacitor) and polycarbonate capacitor.

[0003] At present, when processing capacitor film, slitting equipment is needed to perform slitting operations, and then the film is cut into the required width. However, the survey found that the cutting distance of traditional capacitor film slitting equipment is mostly fixed and non-adjustable. This makes it difficult to meet the use requirements when slitting films of different widths. Different types of cutting machines are often required, which lack adjustability.

[0004] Therefore, in view of this, the applicant has studied and improved the existing structural deficiencies and proposed an adjustable capacitor film processing slitting device to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 5 As shown, an adjustable slitting device for processing capacitor film includes an equipment base 1, and retractable reels 3 are installed at both ends of the top of the equipment base 1, and a cutting frame 2 is installed in the middle position of the top of the equipment base 1. It is characterized in that a cutting part 4 is installed inside the cutting frame 2, and the cutting part 4 includes a bidirectional screw rod 1 41 and a bidirectional screw rod 2 42 rotatably connected to the inner wall of the cutting frame 2, the bidirectional screw rod 1 41 is located above the bidirectional screw rod 2 42, and the pitch of the bidirectional screw rod 1 41 is greater than that of the bidirectional screw rod 2 42, and moving blocks 43 are threadedly connected at both sides of the bidirectional screw rod 1 41 and the bidirectional screw rod 2 42, a curved rod 44 is fixed on one side of the moving block 43, and a slitting knife 45 is installed at the bottom of the curved rod 44, the screw rod 1 41 and the screw rod 2 42 are designed to rotate synchronously in the same direction, and the two moving blocks 43 on the bidirectional screw rod 1 41 are located at both sides of the two moving blocks 43 on the bidirectional screw rod 2 42.

[0023] As mentioned above, by designing the cutting part 4, the slitting knife 45 is set to the common four groups in this case. When the cutter spacing needs to be adjusted, the two-way screw rod 1 41 and the two-way screw rod 2 42 are rotated synchronously in the same direction, so that the two moving blocks 43 on the two-way screw rod 1 41 and the two-way screw rod 2 42 move, and because the thread designs at both ends of the two-way screw rod 1 41 and the two-way screw rod 2 42 are opposite, the moving directions are also opposite. At the same time, through the design of the pitch difference, the moving speed of the moving block 43 on the two-way screw rod 1 41 is greater than the moving speed of the moving block 43 on the two-way screw rod 2 42, so that the four moving blocks 43 remain the same. At this time, the slitting knife 45 is installed at the bottom end of the curved rod 44 to complete the adjustment. Finally, when working, the capacitor film is horizontally operated between the two reel-ups 3 to complete the slitting. It should be noted that the detailed screw parameters are flexibly adjusted according to actual needs and are not limited here.

[0024] A motor 48 is installed on one side of the cutting frame 2, and the motor 48 is connected to the rotating shaft of the two-way screw rod 41. The cutting frame 2 is rotatably connected to two synchronous heads 46 on the other side relative to the motor 48, and the synchronous head 46 is connected to a synchronous belt 47. At the same time, the two synchronous heads 46 are connected to the rotating shafts of the two-way screw rod 41 and the two-way screw rod 42. A clamping block 49 is fixed to the side wall of the moving block 43, and the clamping block 49 slides in the opening of the vertical plate 410, and the vertical plate 410 is fixedly connected to the inner sides and the top of the cutting frame 2. The four curved rods 44 slide outside the horizontal rod 411, and the horizontal rod 411 is fixed to the inner sides of the cutting frame 2. The slitting knife 45 includes a sleeve 451 and a knife head 452. The top opening of the sleeve 451 is inserted by the curved rod 44 and fixed with screws, and the knife head 452 is fixed to the bottom of the sleeve 451.

[0025] As mentioned above, in the optimized design of the cutting part 4, when it is necessary to adjust the rotation of the two-way screw rod 1 41 and the two-way screw rod 2 42, the starting motor 48 drives the two-way screw rod 1 41 to rotate, and at the same time, through the linkage of the synchronous head 46 and the synchronous belt 47, the two-way screw rod 2 42 rotates together, and then the two-way screw rod 1 41 and the two-way screw rod 2 42 rotate in the same direction and at the same speed, which is very convenient. At the same time, the block 49 slides in the opening of the vertical plate 410 to limit the moving block 43, so that it can smoothly move in a straight line on the screw rod. Finally, the curved rod 44 will also slide in a straight line outside the horizontal rod 411 when adjusting the movement, and the horizontal rod 411 provides support for the curved rod 44 to enhance the stability of the curved rod 44. The slitting knife 45 is composed of a sleeve 451 and a knife head 452. When installing, the sleeve 451 is put on the bottom end of the curved rod 44 and screwed to complete the assembly of the knife head 45. This is convenient for disassembly and assembly, which is beneficial to later cleaning and maintenance, and is very practical.

[0026] A support platform 5 having a "U" shape in a top view is installed on the top of the equipment base 1 , the cutting frame 2 is fixed on the top of the support platform 5 , and a dust box 6 is placed in a groove of the support platform 5 of the equipment base 1 .

[0027] As mentioned above, by placing the dust box 6 in the groove of the support platform 5, the fine dust dropped by slitting can be collected to keep the surface of the support platform 5 clean. It should be noted that the dust box 6 is located at the lower position of the slitting knife 45.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
