[0003] Existing die-cutting assembly generally adopts a design scheme with fixed stop rollers and independent chip removal devices, which has the following technical defects:

[0004] 1) The slitting die and dust removal system are set separately, which makes it easy for metal debris to accumulate in the gap between the blades, which not only accelerates the wear of the blade edge, but also causes scratches on the surface of the aluminum foil;

[0005] 2) The rigid positioning structure of the die-cutting side assembly cannot adjust the spacing according to the thickness of the aluminum foil, which results in the dust suction pipe not being able to get close to the die shaft assembly in time. The capture rate of micron-level metal dust generated during the cutting moment is less than 40%, and the residual dust will contaminate the cleanliness of the foil surface.

[0006] Therefore, there is an urgent need to develop die-cutting components with adaptive adjustment and integrated dust removal functions to overcome technical bottlenecks. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Example:

[0033] like Figures 1 to 6 As shown, this application provides a die assembly for a slitting machine for positive and negative aluminum foil of electrolytic capacitors, including: a die body 100, including a die bottom assembly 10, a die front assembly 20 and a die rear assembly 30 disposed on the upper end of the die bottom assembly 10, a die shaft assembly 60 located in the middle of the die front assembly 20 and the die rear assembly 30, and die side assemblies 40 disposed on both sides of the die shaft assembly 60; an adjustment assembly 50 disposed at the connection between the die bottom assembly 10 and the die side assembly 40; the die side assembly 40 includes a side cover plate 41, and a middle part of the side cover plate 41 The die-cutting mold air duct box 42 is provided, the inner dust suction port 43 is opened on one side of the die-cutting mold air duct box 42, and the baffle roller 44 is connected to one side of the side cover plate 41; the adjustment assembly 50 includes an adjustment fixing plate 51 fixedly connected to one side of the die-cutting mold bottom assembly 10, an adjustment screw 52 threadedly connected to the middle of the adjustment fixing plate 51, a top locking rod 53 threadedly connected to the upper end of the adjustment fixing plate 51, an adjustment plate 54 fixedly connected to the bottom of the side cover plate 41, a micrometer head 55 installed on the upper end of the die-cutting mold bottom assembly 10, and a positioning adjustment block 56 connected to the end of the micrometer head 55;

[0034] The front die assembly 20 and the rear die assembly 30 are each provided with a bearing seat in the middle that is adapted to one of the die shaft assemblies 60. The two sets of bearing seats can move along the middle of the front die assembly 20 and the rear die assembly 30 respectively. An adjustment component 50 is also provided at their connection point to finely adjust one of the die shaft assemblies 60, so that it can be used to cut aluminum foil of different thicknesses.

[0035] During the use of the die-cutting body 100, the air outlet on the outside of the side cover plate 41 is connected to the external suction equipment to facilitate dust removal after aluminum foil cutting.

[0036] After adopting the above technical solution, since the adjustment component 50 is set at the connection between the die bottom component 10 and the die side component 40, and the die air duct box 42 is set in the middle of the side cover plate 41, it can solve the problem that the existing die component 100 generally adopts a fixed material blocking roller and an independent chip removal device. The slitting die and the dust removal system are set separately, which makes it easy for metal chips to accumulate in the gap between the blades. This not only accelerates the wear of the blade edge, but also causes scratches on the surface of the aluminum foil. The rigid positioning structure of the die side component 40 cannot adjust the spacing according to the thickness of the aluminum foil (0.01-0.2mm range), which makes it impossible for the dust suction pipe to get close to the die shaft component in time. The capture rate of micron-level metal dust generated at the moment of slitting is less than 40%, and the residual dust will contaminate the cleanliness of the foil surface.

[0037] It should be noted that during the use of the die-cutting body 100, depending on the thickness of the aluminum foil, the gap in the middle of the die-cutting shaft assembly 60 can be changed by adjusting the adjusting component 50 between the die-cutting shaft assembly 60 and the front die-cutting assembly 20 and the rear die-cutting assembly 30. At the same time, rotating the handwheel at the upper end of the base plate 11 causes the handwheel to drive the adjusting screw 52 to rotate along the inside of the adjusting plate 54, causing the adjusting plate 54 to drive the side cover plate 41 to move laterally, and at the same time drive the slider to move along the upper end of the slide rail. Rotating the handwheel in both directions will drive the side cover plate 41 to move laterally. The device moves back and forth. When the side cover plate 41 approaches the mold shaft assembly 60, it will drive the positioning adjustment block 56 to move through the adapter groove, thereby pulling the detection end of the micrometer head 55. The micrometer head 55 can be used to check the moving distance of the side cover plate 41 in time, so that the die-cutting duct box 42 approaches the mold shaft assembly 60. Then, the top locking rod 53 is rotated to lock one end of the adjusting screw 52. Then, the external suction equipment is started to clean the metal debris and dust after the aluminum foil is cut through the die-cutting duct box 42 and the inner dust suction port 43.

[0038] In an optional embodiment, it further includes: an adapter groove formed at the bottom of the side cover plate 41 and adapted to the positioning adjustment block 56, according to the appendix. Figure 3As shown, the positioning adjustment block 56 has an "L" shaped structure. Its end is engaged with the adapter groove. When the side cover plate 41 moves close to the mold shaft assembly 60, the positioning adjustment block 56 can be moved, thereby ensuring that the positioning adjustment block 56 can pull the detection end of the micrometer head 55, so that the micrometer head 55 can check the moving distance of the side cover plate 41 in a timely manner.

[0039] In an optional embodiment, a handwheel is installed at one end of the adjusting screw 52 for easy manual rotation by the user. Alternatively, an electric servo mechanism can be used to drive the adjusting screw 52 to rotate, ensuring that the adjusting screw 52 can rotate smoothly along the inside of the adjusting plate 54, so that the adjusting plate 54 can move laterally along the outside of the adjusting screw 52.

[0040] In an optional embodiment, the bottom of the side cover plate 41 is bolted to a slider, and the upper end of the die-cutting bottom assembly 10 is fitted with a slide rail that is compatible with the slider. During the lateral movement of the side cover plate 41, the slider at the bottom can slide along the upper end of the slide rail at the upper end of the bottom plate 11 to ensure the stability and smoothness of the side cover plate 41 during movement.

[0041] In an optional embodiment, the die-cutting bottom assembly 10 includes a bottom plate 11, a threading guide plate 12 mounted in the middle of the bottom plate 11, and a feed roller 13. By setting the threading guide plate 12, the aluminum foil can be moved along the outside of the threading guide plate 12 during the threading process. Then, it enters the middle of the die-cutting body 100 through the middle of the two sets of feed rollers 13, and is then cut by the die shaft assembly 60.

[0042] In an optional embodiment, the die-cutting front assembly 20 includes a front upright plate 21 and a cutter roller 22 mounted on the upper end of the front upright plate 21. There are two sets of cutter rollers 22, which are symmetrically distributed. After the aluminum foil is cut, multiple sets of aluminum foil will pass through the middle of the two sets of cutter rollers 22 at the same time for subsequent guiding movement. The cutter rollers 22 play an auxiliary role in avoiding burrs, serpentine shapes, straightness and other defects caused by material clamping.
