[0002] In modern industrial production, the slitting process is widely used in many fields, such as packaging material processing, printed product post-processing, leather cutting, electronic material segmentation, etc.

[0003] Traditional slitting devices mostly use fixed-structured cutters and slitting mechanisms, which make it difficult to achieve rapid parameter adjustment. When materials of different thicknesses and widths need to be slid, it is usually necessary to replace the entire cutter die or perform complex and time-consuming manual fine-tuning, and the efficiency of changing the die is low. In addition, in a fixed structure, once a cutter component is worn out or needs to be upgraded, the entire cutter die often needs to be disassembled and reassembled, resulting in a short service life and high maintenance costs. Therefore, those skilled in the art provide a rolling cutter die slitting device to solve the problems raised in the above background technology. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] Please see attached Figures 1 to 9 As shown, frames 2 are fixed on both sides of the upper end surface of the bottom plate 1 in the embodiment of the present invention, and two cutters 4 are rotatably connected between the two frames 2 via an axle seat 3;

[0037] The cutter 4 includes a main shaft 41, a retaining ring 42 is fixed on one side of the main shaft 41, and a screw-connecting column 43 is fixed on the other side. The outer end of the main shaft 41 is sleeved with an outer spacer 45 near the screw-connecting column 43 and the retaining ring 42. A blade 46, a retaining ring spacer 47, a retaining ring 48, and a blade 46 are cyclically arranged between the two outer spacers 45. The retaining ring 48 is sleeved on the outer end of the retaining ring spacer 47, and the inner diameter of the retaining ring 48 is larger than the outer diameter of the retaining ring spacer 47. Because the inner diameter of the retaining ring 48 is larger than the outer diameter of the retaining ring spacer 47, When the retaining ring 48 is subjected to force, the retaining ring 48 will be eccentric to the knife shaft. When adjusting, the outer diameter of the retaining ring 48 is squeezed to the tangent point with the blade, which means it is adjusted into place. Among them, the blade 46 adopts a flat blade, and the two cutters 4 are upper and lower cutters respectively. When the upper and lower blade positions are rolled and cut, the set retaining ring 48 can prevent the material from entering the knife gap during the rolling process. At the same time, the retaining ring 48 can also be used for guiding after cutting, so that the cut materials, such as foil strips, can be better separated, making the discharge smoother.

[0038] Among them, an inner spacer 49 is arranged between two adjacent blades 46, and the retaining rings 48 of the two cutters 4 are staggered. The slitting width of the knife die is determined by the width of the inner spacer 49 and the blade 46. Under the same width of the blade 46, different slitting widths are required, which can be achieved by replacing different inner spacers 49. In addition, because there is a retaining ring 48 outside the retaining ring spacer 47, the inner and outer spacers of the upper and lower knife shafts are staggered. The installation can also better guide the aluminum foil after slitting.

[0039] In this embodiment, the outer end of the screw column 43 is sleeved with a screw sleeve 44, and the screw sleeve 44 abuts against the adjacent outer spacer sleeve 45, and is tightened by the screw sleeve 44 to ensure that the blade 46 is installed tightly. During installation, first install the outer spacer sleeve 45 on the retaining ring 42, and then install the blade 46 → retaining ring spacer sleeve 47 → retaining ring 48 → blade 46 → inner spacer sleeve 49 → blade 46 → retaining ring spacer sleeve 47... and so on, until the required number of slices are aligned, and finally the outer spacer sleeve 45 and the screw sleeve 44 are sleeved.

[0040] In addition, the shaft seat 3 is fixed to the frame 2 by screws, and a knife adjusting block 9 is arranged between the two shaft seats 3. The knife adjusting block 9 is not fixed to the frame 2, but is only clamped between the two shaft seats 3. By replacing the knife adjusting blocks 9 of different thicknesses, different engagement depths (i.e., cutting depths) can be replaced. When the cutting edge of the blade 46 is worn and the blade diameter becomes smaller, it can be adjusted by replacing the knife adjusting block 9 so that the blade 46 can be reused.

[0041] One end of the two cutters 4 is fixedly sleeved with a gear 6, and the two gears 6 are meshed and connected with each other. One cutter 4 is driven to rotate by an external driving device (not shown), and the other cutter 4 is driven to rotate through the gear 6, thereby realizing rolling cutting.

[0042] Parametric adjustment mechanisms 5 are fixed on both sides of the bottom plate 1 , and the parametric adjustment mechanisms 5 are used to adjust the position and angle of the retaining ring 48 .

[0043] Embodiment 2

[0044] See also Figures 1 to 4 As shown, on the basis of embodiment one, the parametric adjustment mechanism 5 includes a mounting plate 51 fixed to the base plate 1, the upper end surface of the mounting plate 51 is slidably connected to a bracket 53 via a guide rail slider 52, the upper and lower sides of the bracket 53 are fixed with an axial pressure roller seat 54 by screws, the inner side of the bracket 53 is rotatably connected to a ring material pressure roller 56, and the ring material pressure roller 56 is in contact with the material blocking ring 48.

[0045] The parameterized adjustment mechanism 5 is used to adjust the angle and position of the retaining ring 48. Because the outer diameter of the retaining ring spacer 47 is smaller than the inner diameter of the retaining ring 48, the retaining ring 48 will have a natural vertical force, so that the retaining ring 48 and the knife shaft are in an eccentric state. Therefore, the angle and position of the retaining ring 48 can be adjusted by squeezing the retaining ring 48 through two ring material pressing rollers 56 to ensure that the tangent point between the retaining ring 48 and the blade 46 is located within the shearing area of ​​the knife shaft.

[0046] Among them, an adjusting stud 57 is sleeved in the middle of the mounting plate 51, and an adjusting seat 58 is sleeved on the outer end of the adjusting stud 57. The adjusting seat 58 is fixedly connected to the middle of the lower end surface of the bracket 53; the rear ends of the two axial pressure roller seats 54 are provided with adjusting grooves 55, and the center of the adjusting grooves 55 is consistent with the screw mounting hole position of the axial pressure roller seat 54. By setting the adjusting grooves 55, the axial pressure roller seat 54 can adjust the installation angle by rotation, and then adjust the angle of the ring material pressure roller 56. In addition, a guide rail slider 52 and an adjusting stud 57 are also provided. When the cutting die needs to be changed, the position of the bracket 53 can be adjusted by rotating the adjusting stud 57 to make space without changing the angle of the ring material pressure roller 56. When the change is completed, the ring material pressure roller 56 is moved by rotating the adjusting stud 57 to extrude the blocking ring 48.

[0047] It should be noted that the ring material pressing roller 56 is rotatably connected to the axial pressing roller seat 54 . When the ring material pressing roller 56 squeezes the retaining ring 48 , the ring material pressing roller 56 will rotate accordingly, thereby reducing the wear on the retaining ring 48 due to contact friction.

[0048] Embodiment 3

[0049] See also Figures 1 to 3As shown, on the basis of embodiment 1, a guide assembly 7 is arranged above the two cutters 4, and the guide assembly 7 includes two mounting frames 71 and a fixing rod 73. The two mounting frames 71 are respectively fixedly connected to the middle of the upper end surfaces of the two frames 2, and two guide rollers 72 are rotatably connected therebetween. The two mounting frames 71 are respectively fixedly connected to the two sides between the two frames 2, and a baffle 74 inclined toward the cutter 4 is fixed on the opposite side. The guide rollers 72 and the baffle 74 are arranged to facilitate guiding the feed.

[0050] In addition, in order to facilitate the discharge of the cut materials, a discharge port is provided on the end surface of the bottom plate 1 away from the cutter 4, and a discharge roller 8 is rotatably connected to the inner side of the discharge port.

[0051] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
