Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.
[0020] like Figures 1 to 3 As shown, a slitting device for producing high-barrier films comprises a workbench 1, a support roller 11 and a slitting mechanism; the slitting mechanism comprises a slitting frame 2, a power device 3, a slider 32, a cross plate 4, a leveling roller 41 and a connecting rod 5; the slitting frames 2 are arranged on both sides of the workbench 1, and the support rollers 11 are arranged on both sides of the slitting frame 2; the support rollers 11 are arranged on both sides of the slitting frame 2 to support and guide the high-barrier film to be slit, thereby ensuring its stability and smoothness during the slitting process.
[0021] The power device 3 is arranged on the top of the slitting frame 2, and a first screw rod 31 is arranged in the slitting frame 2, and the first screw rod 31 is connected to the output end of the power device 3; the slider 32 is arranged on the first screw rod 31; the two ends of the connecting rod 5 are respectively connected to the sliders 32 on both sides; a slitting knife 71 is arranged at the bottom of the connecting rod 5; a slide groove 21 is arranged on the outer wall of the slitting frame 2, and the cross plate 4 is arranged on the outer wall of the slitting frame 2, and the middle position of the cross plate 4 passes through the slide groove 21 and is connected to the slider 32; the leveling roller 41 is arranged at both ends of the cross plate 4; and the projection of the leveling roller 41 on the horizontal plane coincides with the support roller 11.
[0022] The first screw rod 31 is driven to rotate by the power device 3, which drives the slider 32 to move up and down, thereby realizing the up and down movement of the connecting rod 5 connecting the sliders 32 on both sides, and the slitting knife 71 is driven to move by the connecting rod 5 to realize the slitting of the high-barrier membrane. When the slitting knife 71 moves downward, the slider 32 synchronously drives the cross plate 4 to move, and the projection of the leveling roller 41 on the horizontal plane coincides with the support roller 11, so that the leveling roller 41 levels the slit high-barrier membrane, thereby avoiding wrinkles and unevenness on the surface of the high-barrier membrane when the slitting knife 71 contacts the high-barrier membrane, thereby further improving the slitting quality.
[0023] A winding roller 13 is disposed on the workbench 1 , a tension roller 12 is disposed on one side of the winding roller 13 , and the tension roller 12 is disposed between the winding roller 13 and the supporting roller 11 .
[0024] By arranging the tension roller 12 between the winding roller 13 and the supporting roller 11, the tension of the high-barrier film during the winding process can be effectively controlled. This helps to maintain the flatness and tightness of the high-barrier film, avoid wrinkles or looseness during the winding process, and thus ensure product quality.
[0025] A movable groove 51 is provided at the bottom of the connecting rod 5, and a driving device 6 is arranged in the movable groove 51. The output end of the driving device 6 is connected to a second screw rod 61, and the second screw rod 61 is rotatably arranged in the movable groove 51; a movable block 7 is arranged on the second screw rod 61, and the slitting knife 71 is arranged on the movable block 7.
[0026] By driving the second screw rod 61 to rotate through the driving device 6, the positions of the moving block 7 and the slitting knife 71 can be adjusted to meet the needs of different production batches, including changing the slitting size or processing different types of high-barrier films, and the scope of application is wider.
[0027] The slitting knife 71 is threadedly connected to the moving block 7 .
[0028] The slitting knife 71 is threadedly connected to the moving block 7, which is convenient for installation and disassembly. When slitting high-barrier membranes of different thicknesses and materials, the appropriate slitting knife 71 can be quickly replaced to ensure appropriate contact pressure during the slitting process, thereby avoiding poor slitting or damage to the high-barrier membrane caused by being too tight or too loose, and improving the slitting quality and applicability.
[0029] The leveling roller 41 is located above the slitting knife 71 in vertical and horizontal projections.
[0030] By setting the leveling roller 41 above the slitting knife 71, during the slitting operation, the slitting knife 71 first slits the high-barrier membrane, and then, through the connection between the leveling roller 41 and the support roller 11, the high-barrier membrane is leveled, thereby reducing wrinkles and unevenness on the surface of the high-barrier membrane during the slitting operation of the slitting knife 71, and improving the slitting quality. The distance between the leveling roller 41 and the slitting knife 71 is specifically set according to the actual work, so as to avoid the leveling roller 41 and the slitting knife 71 from causing obstruction to the slitting knife 71 when they move synchronously.
[0031] The working principle of the utility model is as follows: First, the high-barrier film to be cut is supported and guided by the support roller 11. When passing through the cutting frame 2, the first screw 31 at the top of the cutting frame 2 is driven to rotate by the power device 3, thereby driving the slider 32 to move up and down. The slider 32 is connected by the connecting rod 5, so that the connecting rod 5 also moves up and down synchronously, thereby driving the cutting knife 71 at the bottom to cut the high-barrier film.
[0032] During the downward movement of the slitting blade 71, the slider 32 simultaneously drives the cross plate 4 to move along the slide groove 21 of the outer wall of the slitting frame 2, so that the leveling rollers 41 and the support rollers 11 disposed at both ends of the cross plate 4 are close to each other. The leveling rollers 41 level the high-barrier film during the slitting process. After the slitting is completed, the slit high-barrier film is continuously transported forward through the support rollers 11, and the tension is controlled by the elastic rollers 12 disposed on one side of the winding rollers 13 to ensure that the flatness and tightness are maintained during the winding process.
[0033] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
